G-Codes¶
This document describes the commands that Klipper supports. These are commands that one may enter into the OctoPrint terminal tab.
G-Code commands¶
Klipper supports the following standard G-Code commands:
- Move (G0 or G1):
G1 [X<pos>] [Y<pos>] [Z<pos>] [E<pos>] [F<speed>]
- Dwell:
G4 P<milliseconds>
- Move to origin:
G28 [X] [Y] [Z]
- Turn off motors:
M18
orM84
- Wait for current moves to finish:
M400
- Use absolute/relative distances for extrusion:
M82
,M83
- Use absolute/relative coordinates:
G90
,G91
- Set position:
G92 [X<pos>] [Y<pos>] [Z<pos>] [E<pos>]
- Set speed factor override percentage:
M220 S<percent>
- Set extrude factor override percentage:
M221 S<percent>
- Set acceleration:
M204 S<value>
ORM204 P<value> T<value>
- Note: If S is not specified and both P and T are specified, then the acceleration is set to the minimum of P and T. If only one of P or T is specified, the command has no effect.
- Get extruder temperature:
M105
- Set extruder temperature:
M104 [T<index>] [S<temperature>]
- Set extruder temperature and wait:
M109 [T<index>] S<temperature>
- Note: M109 always waits for temperature to settle at requested value
- Set bed temperature:
M140 [S<temperature>]
- Set bed temperature and wait:
M190 S<temperature>
- Note: M190 always waits for temperature to settle at requested value
- Set fan speed:
M106 S<value>
- Turn fan off:
M107
- Emergency stop:
M112
- Get current position:
M114
- Get firmware version:
M115
For further details on the above commands see the RepRap G-Code documentation.
Klipper's goal is to support the G-Code commands produced by common 3rd party software (eg, OctoPrint, Printrun, Slic3r, Cura, etc.) in their standard configurations. It is not a goal to support every possible G-Code command. Instead, Klipper prefers human readable "extended G-Code commands". Similarly, the G-Code terminal output is only intended to be human readable - see the API Server document if controlling Klipper from external software.
If one requires a less common G-Code command then it may be possible
to implement it with a custom
gcode_macro config section. For
example, one might use this to implement: G12
, G29
, G30
, G31
,
M42
, M80
, M81
, T1
, etc.
Additional Commands¶
Klipper uses "extended" G-Code commands for general configuration and
status. These extended commands all follow a similar format - they
start with a command name and may be followed by one or more
parameters. For example: SET_SERVO SERVO=myservo ANGLE=5.3
. In this
document, the commands and parameters are shown in uppercase, however
they are not case sensitive. (So, "SET_SERVO" and "set_servo" both run
the same command.)
This section is organized by Klipper module name, which generally follows the section names specified in the printer configuration file. Note that some modules are automatically loaded.
[adxl345]¶
The following commands are available when an adxl345 config section is enabled.
ACCELEROMETER_MEASURE¶
ACCELEROMETER_MEASURE [CHIP=<config_name>] [NAME=<value>]
: Starts
accelerometer measurements at the requested number of samples per
second. If CHIP is not specified it defaults to "adxl345". The command
works in a start-stop mode: when executed for the first time, it
starts the measurements, next execution stops them. The results of
measurements are written to a file named
/tmp/adxl345-<chip>-<name>.csv
where <chip>
is the name of the
accelerometer chip (my_chip_name
from [adxl345 my_chip_name]
) and
<name>
is the optional NAME parameter. If NAME is not specified it
defaults to the current time in "YYYYMMDD_HHMMSS" format. If the
accelerometer does not have a name in its config section (simply
[adxl345]
) then <chip>
part of the name is not generated.
ACCELEROMETER_QUERY¶
ACCELEROMETER_QUERY [CHIP=<config_name>] [RATE=<value>]
: queries
accelerometer for the current value. If CHIP is not specified it
defaults to "adxl345". If RATE is not specified, the default value is
used. This command is useful to test the connection to the ADXL345
accelerometer: one of the returned values should be a free-fall
acceleration (+/- some noise of the chip).
ACCELEROMETER_DEBUG_READ¶
ACCELEROMETER_DEBUG_READ [CHIP=<config_name>] REG=<register>
:
queries ADXL345 register "register" (e.g. 44 or 0x2C). Can be useful
for debugging purposes.
ACCELEROMETER_DEBUG_WRITE¶
ACCELEROMETER_DEBUG_WRITE [CHIP=<config_name>] REG=<register>
VAL=<value>
: Writes raw "value" into a register "register". Both
"value" and "register" can be a decimal or a hexadecimal integer. Use
with care, and refer to ADXL345 data sheet for the reference.
[angle]¶
The following commands are available when an angle config section is enabled.
ANGLE_CALIBRATE¶
ANGLE_CALIBRATE CHIP=<chip_name>
: Perform angle calibration on the
given sensor (there must be an [angle chip_name]
config section that
has specified a stepper
parameter). IMPORTANT - this tool will
command the stepper motor to move without checking the normal
kinematic boundary limits. Ideally the motor should be disconnected
from any printer carriage before performing calibration. If the
stepper can not be disconnected from the printer, make sure the
carriage is near the center of its rail before starting calibration.
(The stepper motor may move forwards or backwards two full rotations
during this test.) After completing this test use the SAVE_CONFIG
command to save the calibration data to the config file. In order to
use this tool the Python "numpy" package must be installed (see the
measuring resonance document
for more information).
ANGLE_CHIP_CALIBRATE¶
ANGLE_CHIP_CALIBRATE CHIP=<chip_name>
: Perform internal sensor calibration,
if implemented (MT6826S/MT6835).
- MT68XX: The motor should be disconnected from any printer carriage before performing calibration. After calibration, the sensor should be reset by disconnecting the power.
ANGLE_DEBUG_READ¶
ANGLE_DEBUG_READ CHIP=<config_name> REG=<register>
: Queries sensor
register "register" (e.g. 44 or 0x2C). Can be useful for debugging
purposes. This is only available for tle5012b chips.
ANGLE_DEBUG_WRITE¶
ANGLE_DEBUG_WRITE CHIP=<config_name> REG=<register> VAL=<value>
:
Writes raw "value" into register "register". Both "value" and
"register" can be a decimal or a hexadecimal integer. Use with care,
and refer to sensor data sheet for the reference. This is only
available for tle5012b chips.
[axis_twist_compensation]¶
The following commands are available when the axis_twist_compensation config section is enabled.
AXIS_TWIST_COMPENSATION_CALIBRATE¶
AXIS_TWIST_COMPENSATION_CALIBRATE [AXIS=<X|Y>] [AUTO=<True|False>]
[SAMPLE_COUNT=<value>]
Calibrates axis twist compensation by specifying the target axis or enabling automatic calibration.
- AXIS: Define the axis (
X
orY
) for which the twist compensation will be calibrated. If not specified, the axis defaults to'X'
.
- AUTO: Enables automatic calibration mode. When
AUTO=True
, the calibration will run for both the X and Y axes. In this mode,AXIS
cannot be specified. If bothAXIS
andAUTO
are provided, an error will be raised.
[bed_mesh]¶
The following commands are available when the bed_mesh config section is enabled (also see the bed mesh guide).
BED_MESH_CALIBRATE¶
BED_MESH_CALIBRATE [PROFILE=<name>] [METHOD=manual] [HORIZONTAL_MOVE_Z=<value>]
[<probe_parameter>=<value>] [<mesh_parameter>=<value>] [ADAPTIVE=1]
[ADAPTIVE_MARGIN=<value>]
: This command probes the bed using generated points
specified by the parameters in the config. After probing, a mesh is generated
and z-movement is adjusted according to the mesh.
The mesh will be saved into a profile specified by the PROFILE
parameter,
or default
if unspecified.
See the PROBE command for details on the optional probe parameters. If
METHOD=manual is specified then the manual probing tool is activated - see the
MANUAL_PROBE command above for details on the additional commands available
while this tool is active. The optional HORIZONTAL_MOVE_Z
value overrides the
horizontal_move_z
option specified in the config file. If ADAPTIVE=1 is
specified then the objects defined by the Gcode file being printed will be used
to define the probed area. The optional ADAPTIVE_MARGIN
value overrides the
adaptive_margin
option specified in the config file.
BED_MESH_OUTPUT¶
BED_MESH_OUTPUT PGP=[<0:1>]
: This command outputs the current probed
z values and current mesh values to the terminal. If PGP=1 is
specified the X, Y coordinates generated by bed_mesh, along with their
associated indices, will be output to the terminal.
BED_MESH_MAP¶
BED_MESH_MAP
: Like to BED_MESH_OUTPUT, this command prints the
current state of the mesh to the terminal. Instead of printing the
values in a human readable format, the state is serialized in json
format. This allows octoprint plugins to easily capture the data and
generate height maps approximating the bed's surface.
BED_MESH_CLEAR¶
BED_MESH_CLEAR
: This command clears the mesh and removes all z
adjustment. It is recommended to put this in your end-gcode.
BED_MESH_PROFILE¶
BED_MESH_PROFILE LOAD=<name> SAVE=<name> REMOVE=<name>
: This command
provides profile management for mesh state. LOAD will restore the mesh
state from the profile matching the supplied name. SAVE will save the
current mesh state to a profile matching the supplied name. Remove
will delete the profile matching the supplied name from persistent
memory. Note that after SAVE or REMOVE operations have been run the
SAVE_CONFIG gcode must be run to make the changes to persistent memory
permanent.
BED_MESH_OFFSET¶
BED_MESH_OFFSET [X=<value>] [Y=<value>] [ZFADE=<value]
: Applies X, Y,
and/or ZFADE offsets to the mesh lookup. This is useful for printers with
independent extruders, as an offset is necessary to produce correct Z
adjustment after a tool change. Note that a ZFADE offset does not apply
additional z-adjustment directly, it is used to correct the fade
calculation when a gcode offset
has been applied to the Z axis.
[bed_screws]¶
The following commands are available when the bed_screws config section is enabled (also see the manual level guide).
BED_SCREWS_ADJUST¶
BED_SCREWS_ADJUST
: This command will invoke the bed screws
adjustment tool. It will command the nozzle to different locations (as
defined in the config file) and allow one to make adjustments to the
bed screws so that the bed is a constant distance from the nozzle.
[bed_tilt]¶
The following commands are available when the bed_tilt config section is enabled.
BED_TILT_CALIBRATE¶
BED_TILT_CALIBRATE [METHOD=manual] [HORIZONTAL_MOVE_Z=<value>]
[<probe_parameter>=<value>]
: This command will probe the points specified in
the config and then recommend updated x and y tilt adjustments. See the PROBE
command for details on the optional probe parameters. If METHOD=manual is
specified then the manual probing tool is activated - see the MANUAL_PROBE
command above for details on the additional commands available while this tool
is active. The optional HORIZONTAL_MOVE_Z
value overrides the
horizontal_move_z
option specified in the config file.
[bltouch]¶
The following command is available when a bltouch config section is enabled (also see the BL-Touch guide).
BLTOUCH_DEBUG¶
BLTOUCH_DEBUG COMMAND=<command>
: This sends a command to the
BLTouch. It may be useful for debugging. Available commands are:
pin_down
, touch_mode
, pin_up
, self_test
, reset
. A BL-Touch
V3.0 or V3.1 may also support set_5V_output_mode
,
set_OD_output_mode
, output_mode_store
commands.
BLTOUCH_STORE¶
BLTOUCH_STORE MODE=<output_mode>
: This stores an output mode in the
EEPROM of a BLTouch V3.1 Available output_modes are: 5V
, OD
[configfile]¶
The configfile module is automatically loaded.
SAVE_CONFIG¶
SAVE_CONFIG
: This command will overwrite the main printer config
file and restart the host software. This command is used in
conjunction with other calibration commands to store the results of
calibration tests.
[delayed_gcode]¶
The following command is enabled if a delayed_gcode config section has been enabled (also see the template guide).
UPDATE_DELAYED_GCODE¶
UPDATE_DELAYED_GCODE [ID=<name>] [DURATION=<seconds>]
: Updates the
delay duration for the identified [delayed_gcode] and starts the timer
for gcode execution. A value of 0 will cancel a pending delayed gcode
from executing.
[delta_calibrate]¶
The following commands are available when the delta_calibrate config section is enabled (also see the delta calibrate guide).
DELTA_CALIBRATE¶
DELTA_CALIBRATE [METHOD=manual] [HORIZONTAL_MOVE_Z=<value>]
[<probe_parameter>=<value>]
: This command will probe seven points on the bed
and recommend updated endstop positions, tower angles, and radius. See the
PROBE command for details on the optional probe parameters. If METHOD=manual is
specified then the manual probing tool is activated - see the MANUAL_PROBE
command above for details on the additional commands available while this tool
is active. The optional HORIZONTAL_MOVE_Z
value overrides the
horizontal_move_z
option specified in the config file.
DELTA_ANALYZE¶
DELTA_ANALYZE
: This command is used during enhanced delta
calibration. See Delta Calibrate for details.
[display]¶
The following command is available when a display config section is enabled.
SET_DISPLAY_GROUP¶
SET_DISPLAY_GROUP [DISPLAY=<display>] GROUP=<group>
: Set the active
display group of an lcd display. This allows to define multiple
display data groups in the config, e.g. [display_data <group>
<elementname>]
and switch between them using this extended gcode
command. If DISPLAY is not specified it defaults to "display" (the
primary display).
[display_status]¶
The display_status module is automatically loaded if a display config section is enabled. It provides the following standard G-Code commands:
- Display Message:
M117 <message>
- Set build percentage:
M73 P<percent>
Also provided is the following extended G-Code command:
SET_DISPLAY_TEXT MSG=<message>
: Performs the equivalent of M117, setting the suppliedMSG
as the current display message. IfMSG
is omitted the display will be cleared.
[dual_carriage]¶
The following command is available when the dual_carriage config section is enabled.
SET_DUAL_CARRIAGE¶
SET_DUAL_CARRIAGE CARRIAGE=[0|1] [MODE=[PRIMARY|COPY|MIRROR]]
:
This command will change the mode of the specified carriage.
If no MODE
is provided it defaults to PRIMARY
. Setting the mode
to PRIMARY
deactivates the other carriage and makes the specified
carriage execute subsequent G-Code commands as-is. COPY
and MIRROR
modes are supported only for CARRIAGE=1
. When set to either of these
modes, carriage 1 will then track the subsequent moves of the carriage 0
and either copy relative movements of it (in COPY
mode) or execute them
in the opposite (mirror) direction (in MIRROR
mode).
SAVE_DUAL_CARRIAGE_STATE¶
SAVE_DUAL_CARRIAGE_STATE [NAME=<state_name>]
: Save the current positions
of the dual carriages and their modes. Saving and restoring DUAL_CARRIAGE
state can be useful in scripts and macros, as well as in homing routine
overrides. If NAME is provided it allows one to name the saved state
to the given string. If NAME is not provided it defaults to "default".
RESTORE_DUAL_CARRIAGE_STATE¶
RESTORE_DUAL_CARRIAGE_STATE [NAME=<state_name>] [MOVE=[0|1] [MOVE_SPEED=<speed>]]
:
Restore the previously saved positions of the dual carriages and their modes,
unless "MOVE=0" is specified, in which case only the saved modes will be
restored, but not the positions of the carriages. If positions are being
restored and "MOVE_SPEED" is specified, then the toolhead moves will be
performed with the given speed (in mm/s); otherwise the toolhead move will
use the rail homing speed. Note that the carriages restore their positions
only over their own axis, which may be necessary to correctly restore COPY
and MIRROR mode of the dual carraige.
[endstop_phase]¶
The following commands are available when an endstop_phase config section is enabled (also see the endstop phase guide).
ENDSTOP_PHASE_CALIBRATE¶
ENDSTOP_PHASE_CALIBRATE [STEPPER=<config_name>]
: If no STEPPER
parameter is provided then this command will reports statistics on
endstop stepper phases during past homing operations. When a STEPPER
parameter is provided it arranges for the given endstop phase setting
to be written to the config file (in conjunction with the SAVE_CONFIG
command).
[exclude_object]¶
The following commands are available when an exclude_object config section is enabled (also see the exclude object guide):
EXCLUDE_OBJECT
¶
EXCLUDE_OBJECT [NAME=object_name] [CURRENT=1] [RESET=1]
:
With no parameters, this will return a list of all currently excluded objects.
When the NAME
parameter is given, the named object will be excluded from
printing.
When the CURRENT
parameter is given, the current object will be excluded from
printing.
When the RESET
parameter is given, the list of excluded objects will be
cleared. Additionally including NAME
will only reset the named object. This
can cause print failures, if layers were already skipped.
EXCLUDE_OBJECT_DEFINE
¶
EXCLUDE_OBJECT_DEFINE [NAME=object_name [CENTER=X,Y] [POLYGON=[[x,y],...]]
[RESET=1] [JSON=1]
:
Provides a summary of an object in the file.
With no parameters provided, this will list the defined objects known to
Klipper. Returns a list of strings, unless the JSON
parameter is given,
when it will return object details in json format.
When the NAME
parameter is included, this defines an object to be excluded.
NAME
: This parameter is required. It is the identifier used by other commands in this module.CENTER
: An X,Y coordinate for the object.POLYGON
: An array of X,Y coordinates that provide an outline for the object.
When the RESET
parameter is provided, all defined objects will be cleared, and
the [exclude_object]
module will be reset.
EXCLUDE_OBJECT_START
¶
EXCLUDE_OBJECT_START NAME=object_name
:
This command takes a NAME
parameter and denotes the start of the gcode for an
object on the current layer.
EXCLUDE_OBJECT_END
¶
EXCLUDE_OBJECT_END [NAME=object_name]
:
Denotes the end of the object's gcode for the layer. It is paired with
EXCLUDE_OBJECT_START
. A NAME
parameter is optional, and will only warn when
the provided name does not match the current object.
[extruder]¶
The following commands are available if an extruder config section is enabled:
ACTIVATE_EXTRUDER¶
ACTIVATE_EXTRUDER EXTRUDER=<config_name>
: In a printer with multiple
extruder config sections, this command
changes the active hotend.
SET_PRESSURE_ADVANCE¶
SET_PRESSURE_ADVANCE [EXTRUDER=<config_name>]
[ADVANCE=<pressure_advance>]
[SMOOTH_TIME=<pressure_advance_smooth_time>]
: Set pressure advance
parameters of an extruder stepper (as defined in an
extruder or
extruder_stepper config section).
If EXTRUDER is not specified, it defaults to the stepper defined in
the active hotend.
SET_EXTRUDER_ROTATION_DISTANCE¶
SET_EXTRUDER_ROTATION_DISTANCE EXTRUDER=<config_name>
[DISTANCE=<distance>]
: Set a new value for the provided extruder
stepper's "rotation distance" (as defined in an
extruder or
extruder_stepper config section).
If the rotation distance is a negative number then the stepper motion
will be inverted (relative to the stepper direction specified in the
config file). Changed settings are not retained on Klipper reset. Use
with caution as small changes can result in excessive pressure between
extruder and hotend. Do proper calibration with filament before use.
If 'DISTANCE' value is not provided then this command will return the
current rotation distance.
SYNC_EXTRUDER_MOTION¶
SYNC_EXTRUDER_MOTION EXTRUDER=<name> MOTION_QUEUE=<name>
: This
command will cause the stepper specified by EXTRUDER (as defined in an
extruder or
extruder_stepper config section)
to become synchronized to the movement of an extruder specified by
MOTION_QUEUE (as defined in an extruder
config section). If MOTION_QUEUE is an empty string then the stepper
will be desynchronized from all extruder movement.
[fan_generic]¶
The following command is available when a fan_generic config section is enabled.
SET_FAN_SPEED¶
SET_FAN_SPEED FAN=config_name SPEED=<speed>
This command sets the
speed of a fan. "speed" must be between 0.0 and 1.0.
SET_FAN_SPEED PIN=config_name TEMPLATE=<template_name>
[<param_x>=<literal>]
: If TEMPLATE
is specified then it assigns a
display_template to the given
fan. For example, if one defined a [display_template
my_fan_template]
config section then one could assign
TEMPLATE=my_fan_template
here. The display_template should produce a
string containing a floating point number with the desired value. The
template will be continuously evaluated and the fan will be
automatically set to the resulting speed. One may set display_template
parameters to use during template evaluation (parameters will be
parsed as Python literals). If TEMPLATE is an empty string then this
command will clear any previous template assigned to the pin (one can
then use SET_FAN_SPEED
commands to manage the values directly).
[filament_switch_sensor]¶
The following command is available when a filament_switch_sensor or filament_motion_sensor config section is enabled.
QUERY_FILAMENT_SENSOR¶
QUERY_FILAMENT_SENSOR SENSOR=<sensor_name>
: Queries the current
status of the filament sensor. The data displayed on the terminal will
depend on the sensor type defined in the configuration.
SET_FILAMENT_SENSOR¶
SET_FILAMENT_SENSOR SENSOR=<sensor_name> ENABLE=[0|1]
: Sets the
filament sensor on/off. If ENABLE is set to 0, the filament sensor
will be disabled, if set to 1 it is enabled.
[firmware_retraction]¶
The following standard G-Code commands are available when the firmware_retraction config section is enabled. These commands allow you to utilize the firmware retraction feature available in many slicers, to reduce stringing during non-extrusion moves from one part of the print to another. Appropriately configuring pressure advance reduces the length of retraction required.
G10
: Retracts the extruder using the currently configured parameters.G11
: Unretracts the extruder using the currently configured parameters.
The following additional commands are also available.
SET_RETRACTION¶
SET_RETRACTION [RETRACT_LENGTH=<mm>] [RETRACT_SPEED=<mm/s>]
[UNRETRACT_EXTRA_LENGTH=<mm>] [UNRETRACT_SPEED=<mm/s>]
: Adjust the
parameters used by firmware retraction. RETRACT_LENGTH determines the
length of filament to retract and unretract. The speed of retraction
is adjusted via RETRACT_SPEED, and is typically set relatively
high. The speed of unretraction is adjusted via UNRETRACT_SPEED, and
is not particularly critical, although often lower than RETRACT_SPEED.
In some cases it is useful to add a small amount of additional length
on unretraction, and this is set via UNRETRACT_EXTRA_LENGTH.
SET_RETRACTION is commonly set as part of slicer per-filament
configuration, as different filaments require different parameter
settings.
GET_RETRACTION¶
GET_RETRACTION
: Queries the current parameters used by firmware
retraction and displays them on the terminal.
[force_move]¶
The force_move module is automatically loaded, however some commands
require setting enable_force_move
in the
printer config.
STEPPER_BUZZ¶
STEPPER_BUZZ STEPPER=<config_name>
: Move the given stepper forward
one mm and then backward one mm, repeated 10 times. This is a
diagnostic tool to help verify stepper connectivity.
FORCE_MOVE¶
FORCE_MOVE STEPPER=<config_name> DISTANCE=<value> VELOCITY=<value>
[ACCEL=<value>]
: This command will forcibly move the given stepper
the given distance (in mm) at the given constant velocity (in mm/s).
If ACCEL is specified and is greater than zero, then the given
acceleration (in mm/s^2) will be used; otherwise no acceleration is
performed. No boundary checks are performed; no kinematic updates are
made; other parallel steppers on an axis will not be moved. Use
caution as an incorrect command could cause damage! Using this command
will almost certainly place the low-level kinematics in an incorrect
state; issue a G28 afterwards to reset the kinematics. This command is
intended for low-level diagnostics and debugging.
SET_KINEMATIC_POSITION¶
SET_KINEMATIC_POSITION [X=<value>] [Y=<value>] [Z=<value>]
: Force
the low-level kinematic code to believe the toolhead is at the given
cartesian position. This is a diagnostic and debugging command; use
SET_GCODE_OFFSET and/or G92 for regular axis transformations. If an
axis is not specified then it will default to the position that the
head was last commanded to. Setting an incorrect or invalid position
may lead to internal software errors. This command may invalidate
future boundary checks; issue a G28 afterwards to reset the
kinematics.
[gcode]¶
The gcode module is automatically loaded.
RESTART¶
RESTART
: This will cause the host software to reload its config and
perform an internal reset. This command will not clear error state
from the micro-controller (see FIRMWARE_RESTART) nor will it load new
software (see
the FAQ).
FIRMWARE_RESTART¶
FIRMWARE_RESTART
: This is similar to a RESTART command, but it also
clears any error state from the micro-controller.
STATUS¶
STATUS
: Report the Klipper host software status.
HELP¶
HELP
: Report the list of available extended G-Code commands.
[gcode_arcs]¶
The following standard G-Code commands are available if a gcode_arcs config section is enabled:
- Arc Move Clockwise (G2), Arc Move Counter-clockwise (G3):
G2|G3 [X<pos>] [Y<pos>] [Z<pos>] [E<pos>] [F<speed>] I<value> J<value>|I<value> K<value>|J<value> K<value>
- Arc Plane Select: G17 (XY plane), G18 (XZ plane), G19 (YZ plane)
[gcode_macro]¶
The following command is available when a gcode_macro config section is enabled (also see the command templates guide).
SET_GCODE_VARIABLE¶
SET_GCODE_VARIABLE MACRO=<macro_name> VARIABLE=<name> VALUE=<value>
:
This command allows one to change the value of a gcode_macro variable
at run-time. The provided VALUE is parsed as a Python literal.
[gcode_move]¶
The gcode_move module is automatically loaded.
GET_POSITION¶
GET_POSITION
: Return information on the current location of the
toolhead. See the developer documentation of
GET_POSITION output for more
information.
SET_GCODE_OFFSET¶
SET_GCODE_OFFSET [X=<pos>|X_ADJUST=<adjust>]
[Y=<pos>|Y_ADJUST=<adjust>] [Z=<pos>|Z_ADJUST=<adjust>] [MOVE=1
[MOVE_SPEED=<speed>]]
: Set a positional offset to apply to future
G-Code commands. This is commonly used to virtually change the Z bed
offset or to set nozzle XY offsets when switching extruders. For
example, if "SET_GCODE_OFFSET Z=0.2" is sent, then future G-Code moves
will have 0.2mm added to their Z height. If the X_ADJUST style
parameters are used, then the adjustment will be added to any existing
offset (eg, "SET_GCODE_OFFSET Z=-0.2" followed by "SET_GCODE_OFFSET
Z_ADJUST=0.3" would result in a total Z offset of 0.1). If "MOVE=1" is
specified then a toolhead move will be issued to apply the given
offset (otherwise the offset will take effect on the next absolute
G-Code move that specifies the given axis). If "MOVE_SPEED" is
specified then the toolhead move will be performed with the given
speed (in mm/s); otherwise the toolhead move will use the last
specified G-Code speed.
SAVE_GCODE_STATE¶
SAVE_GCODE_STATE [NAME=<state_name>]
: Save the current g-code
coordinate parsing state. Saving and restoring the g-code state is
useful in scripts and macros. This command saves the current g-code
absolute coordinate mode (G90/G91), absolute extrude mode (M82/M83),
origin (G92), offset (SET_GCODE_OFFSET), speed override (M220),
extruder override (M221), move speed, current XYZ position, and
relative extruder "E" position. If NAME is provided it allows one to
name the saved state to the given string. If NAME is not provided it
defaults to "default".
RESTORE_GCODE_STATE¶
RESTORE_GCODE_STATE [NAME=<state_name>] [MOVE=1
[MOVE_SPEED=<speed>]]
: Restore a state previously saved via
SAVE_GCODE_STATE. If "MOVE=1" is specified then a toolhead move will
be issued to move back to the previous XYZ position. If "MOVE_SPEED"
is specified then the toolhead move will be performed with the given
speed (in mm/s); otherwise the toolhead move will use the restored
g-code speed.
[hall_filament_width_sensor]¶
The following commands are available when the tsl1401cl filament width sensor config section or hall filament width sensor config section is enabled (also see TSLl401CL Filament Width Sensor and Hall Filament Width Sensor):
QUERY_FILAMENT_WIDTH¶
QUERY_FILAMENT_WIDTH
: Return the current measured filament width.
RESET_FILAMENT_WIDTH_SENSOR¶
RESET_FILAMENT_WIDTH_SENSOR
: Clear all sensor readings. Helpful
after filament change.
DISABLE_FILAMENT_WIDTH_SENSOR¶

ENABLE_FILAMENT_WIDTH_SENSOR
: Turn on the filament width sensor and
start using it for flow control.
QUERY_RAW_FILAMENT_WIDTH¶
QUERY_RAW_FILAMENT_WIDTH
: Return the current ADC channel readings
and RAW sensor value for calibration points.
ENABLE_FILAMENT_WIDTH_LOG¶
ENABLE_FILAMENT_WIDTH_LOG
: Turn on diameter logging.
DISABLE_FILAMENT_WIDTH_LOG¶
DISABLE_FILAMENT_WIDTH_LOG
: Turn off diameter logging.
[heaters]¶
The heaters module is automatically loaded if a heater is defined in the config file.
TURN_OFF_HEATERS¶
TURN_OFF_HEATERS
: Turn off all heaters.
TEMPERATURE_WAIT¶
TEMPERATURE_WAIT SENSOR=<config_name> [MINIMUM=<target>]
[MAXIMUM=<target>]
: Wait until the given temperature sensor is at or
above the supplied MINIMUM and/or at or below the supplied MAXIMUM.
SET_HEATER_TEMPERATURE¶
SET_HEATER_TEMPERATURE HEATER=<heater_name>
[TARGET=<target_temperature>]
: Sets the target temperature for a
heater. If a target temperature is not supplied, the target is 0.
[idle_timeout]¶
The idle_timeout module is automatically loaded.
SET_IDLE_TIMEOUT¶
SET_IDLE_TIMEOUT [TIMEOUT=<timeout>]
: Allows the user to set the
idle timeout (in seconds).
[input_shaper]¶
The following command is enabled if an input_shaper config section has been enabled (also see the resonance compensation guide).
SET_INPUT_SHAPER¶
SET_INPUT_SHAPER [SHAPER_FREQ_X=<shaper_freq_x>]
[SHAPER_FREQ_Y=<shaper_freq_y>] [DAMPING_RATIO_X=<damping_ratio_x>]
[DAMPING_RATIO_Y=<damping_ratio_y>] [SHAPER_TYPE=<shaper>]
[SHAPER_TYPE_X=<shaper_type_x>] [SHAPER_TYPE_Y=<shaper_type_y>]
:
Modify input shaper parameters. Note that SHAPER_TYPE parameter resets
input shaper for both X and Y axes even if different shaper types have
been configured in [input_shaper] section. SHAPER_TYPE cannot be used
together with either of SHAPER_TYPE_X and SHAPER_TYPE_Y parameters.
See config reference for more
details on each of these parameters.
[manual_probe]¶
The manual_probe module is automatically loaded.
MANUAL_PROBE¶
MANUAL_PROBE [SPEED=<speed>]
: Run a helper script useful for
measuring the height of the nozzle at a given location. If SPEED is
specified, it sets the speed of TESTZ commands (the default is
5mm/s). During a manual probe, the following additional commands are
available:
ACCEPT
: This command accepts the current Z position and concludes the manual probing tool.ABORT
: This command terminates the manual probing tool.TESTZ Z=<value>
: This command moves the nozzle up or down by the amount specified in "value". For example,TESTZ Z=-.1
would move the nozzle down .1mm whileTESTZ Z=.1
would move the nozzle up .1mm. The value may also be+
,-
,++
, or--
to move the nozzle up or down an amount relative to previous attempts.
Z_ENDSTOP_CALIBRATE¶
Z_ENDSTOP_CALIBRATE [SPEED=<speed>]
: Run a helper script useful for
calibrating a Z position_endstop config setting. See the MANUAL_PROBE
command for details on the parameters and the additional commands
available while the tool is active.
Z_OFFSET_APPLY_ENDSTOP¶
Z_OFFSET_APPLY_ENDSTOP
: Take the current Z Gcode offset (aka,
babystepping), and subtract it from the stepper_z endstop_position.
This acts to take a frequently used babystepping value, and "make it
permanent". Requires a SAVE_CONFIG
to take effect.
[manual_stepper]¶
The following command is available when a manual_stepper config section is enabled.
MANUAL_STEPPER¶
MANUAL_STEPPER STEPPER=config_name [ENABLE=[0|1]]
[SET_POSITION=<pos>] [SPEED=<speed>] [ACCEL=<accel>] [MOVE=<pos>
[STOP_ON_ENDSTOP=[1|2|-1|-2]] [SYNC=0]]
: This command will alter the
state of the stepper. Use the ENABLE parameter to enable/disable the
stepper. Use the SET_POSITION parameter to force the stepper to think
it is at the given position. Use the MOVE parameter to request a
movement to the given position. If SPEED and/or ACCEL is specified
then the given values will be used instead of the defaults specified
in the config file. If an ACCEL of zero is specified then no
acceleration will be performed. If STOP_ON_ENDSTOP=1 is specified then
the move will end early should the endstop report as triggered (use
STOP_ON_ENDSTOP=2 to complete the move without error even if the
endstop does not trigger, use -1 or -2 to stop when the endstop
reports not triggered). Normally future G-Code commands will be
scheduled to run after the stepper move completes, however if a manual
stepper move uses SYNC=0 then future G-Code movement commands may run
in parallel with the stepper movement.
[mcp4018]¶
The following command is available when a mcp4018 config section is enabled.
SET_DIGIPOT¶
SET_DIGIPOT DIGIPOT=config_name WIPER=<value>
: This command will
change the current value of the digipot. This value should typically
be between 0.0 and 1.0, unless a 'scale' is defined in the config.
When 'scale' is defined, then this value should be between 0.0 and
'scale'.
[led]¶
The following command is available when any of the led config sections are enabled.
SET_LED¶
SET_LED LED=<config_name> RED=<value> GREEN=<value> BLUE=<value>
WHITE=<value> [INDEX=<index>] [TRANSMIT=0] [SYNC=1]
: This sets the
LED output. Each color <value>
must be between 0.0 and 1.0. The
WHITE option is only valid on RGBW LEDs. If the LED supports multiple
chips in a daisy-chain then one may specify INDEX to alter the color
of just the given chip (1 for the first chip, 2 for the second,
etc.). If INDEX is not provided then all LEDs in the daisy-chain will
be set to the provided color. If TRANSMIT=0 is specified then the
color change will only be made on the next SET_LED command that does
not specify TRANSMIT=0; this may be useful in combination with the
INDEX parameter to batch multiple updates in a daisy-chain. By
default, the SET_LED command will sync it's changes with other ongoing
gcode commands. This can lead to undesirable behavior if LEDs are
being set while the printer is not printing as it will reset the idle
timeout. If careful timing is not needed, the optional SYNC=0
parameter can be specified to apply the changes without resetting the
idle timeout.
SET_LED_TEMPLATE¶
SET_LED_TEMPLATE LED=<led_name> TEMPLATE=<template_name>
[<param_x>=<literal>] [INDEX=<index>]
: Assign a
display_template to a given
LED. For example, if one defined a
[display_template my_led_template]
config section then one could
assign TEMPLATE=my_led_template
here. The display_template should
produce a comma separated string containing four floating point
numbers corresponding to red, green, blue, and white color settings.
The template will be continuously evaluated and the LED will be
automatically set to the resulting colors. One may set
display_template parameters to use during template evaluation
(parameters will be parsed as Python literals). If INDEX is not
specified then all chips in the LED's daisy-chain will be set to the
template, otherwise only the chip with the given index will be
updated. If TEMPLATE is an empty string then this command will clear
any previous template assigned to the LED (one can then use SET_LED
commands to manage the LED's color settings).
[output_pin]¶
The following command is available when an output_pin config section or pwm_tool config section is enabled.
SET_PIN¶
SET_PIN PIN=config_name VALUE=<value>
: Set the pin to the given
output VALUE
. VALUE should be 0 or 1 for "digital" output pins. For
PWM pins, set to a value between 0.0 and 1.0, or between 0.0 and
scale
if a scale is configured in the output_pin config section.
SET_PIN PIN=config_name TEMPLATE=<template_name> [<param_x>=<literal>]
:
If TEMPLATE
is specified then it assigns a
display_template to the given
pin. For example, if one defined a [display_template
my_pin_template]
config section then one could assign
TEMPLATE=my_pin_template
here. The display_template should produce a
string containing a floating point number with the desired value. The
template will be continuously evaluated and the pin will be
automatically set to the resulting value. One may set display_template
parameters to use during template evaluation (parameters will be
parsed as Python literals). If TEMPLATE is an empty string then this
command will clear any previous template assigned to the pin (one can
then use SET_PIN
commands to manage the values directly).
[palette2]¶
The following commands are available when the palette2 config section is enabled.
Palette prints work by embedding special OCodes (Omega Codes) in the GCode file:
O1
...O32
: These codes are read from the GCode stream and processed by this module and passed to the Palette 2 device.
The following additional commands are also available.
PALETTE_CONNECT¶
PALETTE_CONNECT
: This command initializes the connection with the
Palette 2.
PALETTE_DISCONNECT¶
PALETTE_DISCONNECT
: This command disconnects from the Palette 2.
PALETTE_CLEAR¶
PALETTE_CLEAR
: This command instructs the Palette 2 to clear all of
the input and output paths of filament.
PALETTE_CUT¶
PALETTE_CUT
: This command instructs the Palette 2 to cut the
filament currently loaded in the splice core.
PALETTE_SMART_LOAD¶
PALETTE_SMART_LOAD
: This command start the smart load sequence on
the Palette 2. Filament is loaded automatically by extruding it the
distance calibrated on the device for the printer, and instructs the
Palette 2 once the loading has been completed. This command is the
same as pressing Smart Load directly on the Palette 2 screen after
the filament load is complete.
[pid_calibrate]¶
The pid_calibrate module is automatically loaded if a heater is defined in the config file.
PID_CALIBRATE¶
PID_CALIBRATE HEATER=<config_name> TARGET=<temperature>
[WRITE_FILE=1]
: Perform a PID calibration test. The specified heater
will be enabled until the specified target temperature is reached, and
then the heater will be turned off and on for several cycles. If the
WRITE_FILE parameter is enabled, then the file /tmp/heattest.txt will
be created with a log of all temperature samples taken during the
test.
[pause_resume]¶
The following commands are available when the pause_resume config section is enabled:
PAUSE¶
PAUSE
: Pauses the current print. The current position is captured
for restoration upon resume.
RESUME¶
RESUME [VELOCITY=<value>]
: Resumes the print from a pause, first
restoring the previously captured position. The VELOCITY parameter
determines the speed at which the tool should return to the original
captured position.
CLEAR_PAUSE¶
CLEAR_PAUSE
: Clears the current paused state without resuming the
print. This is useful if one decides to cancel a print after a
PAUSE. It is recommended to add this to your start gcode to make sure
the paused state is fresh for each print.
CANCEL_PRINT¶
CANCEL_PRINT
: Cancels the current print.
[print_stats]¶
The print_stats module is automatically loaded.
SET_PRINT_STATS_INFO¶
SET_PRINT_STATS_INFO [TOTAL_LAYER=<total_layer_count>] [CURRENT_LAYER=
<current_layer>]
: Pass slicer info like layer act and total to Klipper.
Add SET_PRINT_STATS_INFO [TOTAL_LAYER=<total_layer_count>]
to your
slicer start gcode section and SET_PRINT_STATS_INFO [CURRENT_LAYER=
<current_layer>]
at the layer change gcode section to pass layer
information from your slicer to Klipper.
[probe]¶
The following commands are available when a probe config section or bltouch config section is enabled (also see the probe calibrate guide).
PROBE¶
PROBE [PROBE_SPEED=<mm/s>] [LIFT_SPEED=<mm/s>] [SAMPLES=<count>]
[SAMPLE_RETRACT_DIST=<mm>] [SAMPLES_TOLERANCE=<mm>]
[SAMPLES_TOLERANCE_RETRIES=<count>] [SAMPLES_RESULT=median|average]
:
Move the nozzle downwards until the probe triggers. If any of the
optional parameters are provided they override their equivalent
setting in the probe config section.
QUERY_PROBE¶
QUERY_PROBE
: Report the current status of the probe ("triggered" or
"open").
PROBE_ACCURACY¶
PROBE_ACCURACY [PROBE_SPEED=<mm/s>] [SAMPLES=<count>]
[SAMPLE_RETRACT_DIST=<mm>]
: Calculate the maximum, minimum, average,
median, and standard deviation of multiple probe samples. By default,
10 SAMPLES are taken. Otherwise the optional parameters default to
their equivalent setting in the probe config section.
PROBE_CALIBRATE¶
PROBE_CALIBRATE [SPEED=<speed>] [<probe_parameter>=<value>]
: Run a
helper script useful for calibrating the probe's z_offset. See the
PROBE command for details on the optional probe parameters. See the
MANUAL_PROBE command for details on the SPEED parameter and the
additional commands available while the tool is active. Please note,
the PROBE_CALIBRATE command uses the speed variable to move in XY
direction as well as Z.
Z_OFFSET_APPLY_PROBE¶
Z_OFFSET_APPLY_PROBE
: Take the current Z Gcode offset (aka,
babystepping), and subtract if from the probe's z_offset. This acts
to take a frequently used babystepping value, and "make it permanent".
Requires a SAVE_CONFIG
to take effect.
[probe_eddy_current]¶
The following commands are available when a probe_eddy_current config section is enabled.
PROBE_EDDY_CURRENT_CALIBRATE¶
PROBE_EDDY_CURRENT_CALIBRATE CHIP=<config_name>
: This starts a tool
that calibrates the sensor resonance frequencies to corresponding Z
heights. The tool will take a couple of minutes to complete. After
completion, use the SAVE_CONFIG command to store the results in the
printer.cfg file.
LDC_CALIBRATE_DRIVE_CURRENT¶
LDC_CALIBRATE_DRIVE_CURRENT CHIP=<config_name>
This tool will
calibrate the ldc1612 DRIVE_CURRENT0 register. Prior to using this
tool, move the sensor so that it is near the center of the bed and
about 20mm above the bed surface. Run this command to determine an
appropriate DRIVE_CURRENT for the sensor. After running this command
use the SAVE_CONFIG command to store that new setting in the
printer.cfg config file.
[pwm_cycle_time]¶
The following command is available when a pwm_cycle_time config section is enabled.
SET_PIN¶
SET_PIN PIN=config_name VALUE=<value> [CYCLE_TIME=<cycle_time>]
:
This command works similarly to output_pin SET_PIN
commands. The command here supports setting an explicit cycle time
using the CYCLE_TIME parameter (specified in seconds). Note that the
CYCLE_TIME parameter is not stored between SET_PIN commands (any
SET_PIN command without an explicit CYCLE_TIME parameter will use the
cycle_time
specified in the pwm_cycle_time config section).
[query_adc]¶
The query_adc module is automatically loaded.
QUERY_ADC¶
QUERY_ADC [NAME=<config_name>] [PULLUP=<value>]
: Report the last
analog value received for a configured analog pin. If NAME is not
provided, the list of available adc names are reported. If PULLUP is
provided (as a value in Ohms), the raw analog value along with the
equivalent resistance given that pullup is reported.
[query_endstops]¶
The query_endstops module is automatically loaded. The following standard G-Code commands are currently available, but using them is not recommended:
- Get Endstop Status:
M119
(Use QUERY_ENDSTOPS instead.)
QUERY_ENDSTOPS¶
QUERY_ENDSTOPS
: Probe the axis endstops and report if they are
"triggered" or in an "open" state. This command is typically used to
verify that an endstop is working correctly.
[resonance_tester]¶
The following commands are available when a resonance_tester config section is enabled (also see the measuring resonances guide).
MEASURE_AXES_NOISE¶
MEASURE_AXES_NOISE
: Measures and outputs the noise for all axes of
all enabled accelerometer chips.
TEST_RESONANCES¶
TEST_RESONANCES AXIS=<axis> [OUTPUT=<resonances,raw_data>]
[NAME=<name>] [FREQ_START=<min_freq>] [FREQ_END=<max_freq>]
[ACCEL_PER_HZ=<accel_per_hz>] [HZ_PER_SEC=<hz_per_sec>] [CHIPS=<chip_name>]
[POINT=x,y,z] [INPUT_SHAPING=<0:1>]
: Runs the resonance
test in all configured probe points for the requested "axis" and
measures the acceleration using the accelerometer chips configured for
the respective axis. "axis" can either be X or Y, or specify an
arbitrary direction as AXIS=dx,dy
, where dx and dy are floating
point numbers defining a direction vector (e.g. AXIS=X
, AXIS=Y
, or
AXIS=1,-1
to define a diagonal direction). Note that AXIS=dx,dy
and AXIS=-dx,-dy
is equivalent. chip_name
can be one or
more configured accel chips, delimited with comma, for example
CHIPS="adxl345, adxl345 rpi"
. If POINT is specified it will override the point(s)
configured in [resonance_tester]
. If INPUT_SHAPING=0
or not set(default),
disables input shaping for the resonance testing, because
it is not valid to run the resonance testing with the input shaper
enabled. OUTPUT
parameter is a comma-separated list of which outputs
will be written. If raw_data
is requested, then the raw
accelerometer data is written into a file or a series of files
/tmp/raw_data_<axis>_[<chip_name>_][<point>_]<name>.csv
with
(<point>_
part of the name generated only if more than 1 probe point
is configured or POINT is specified). If resonances
is specified, the
frequency response is calculated (across all probe points) and written into
/tmp/resonances_<axis>_<name>.csv
file. If unset, OUTPUT defaults to
resonances
, and NAME defaults to the current time in
"YYYYMMDD_HHMMSS" format.
SHAPER_CALIBRATE¶
SHAPER_CALIBRATE [AXIS=<axis>] [NAME=<name>] [FREQ_START=<min_freq>]
[FREQ_END=<max_freq>] [ACCEL_PER_HZ=<accel_per_hz>][HZ_PER_SEC=<hz_per_sec>]
[CHIPS=<chip_name>] [MAX_SMOOTHING=<max_smoothing>] [INPUT_SHAPING=<0:1>]
:
Similarly to TEST_RESONANCES
, runs
the resonance test as configured, and tries to find the optimal
parameters for the input shaper for the requested axis (or both X and
Y axes if AXIS
parameter is unset). If MAX_SMOOTHING
is unset, its
value is taken from [resonance_tester]
section, with the default
being unset. See the
Max smoothing of the
measuring resonances guide for more information on the use of this
feature. The results of the tuning are printed to the console, and the
frequency responses and the different input shapers values are written
to a CSV file(s) /tmp/calibration_data_<axis>_<name>.csv
. Unless
specified, NAME defaults to the current time in "YYYYMMDD_HHMMSS"
format. Note that the suggested input shaper parameters can be
persisted in the config by issuing SAVE_CONFIG
command, and if
[input_shaper]
was already enabled previously, these parameters
take effect immediately.
[respond]¶
The following standard G-Code commands are available when the respond config section is enabled:
M118 <message>
: echo the message prepended with the configured default prefix (orecho:
if no prefix is configured).
The following additional commands are also available.
RESPOND¶
RESPOND MSG="<message>"
: echo the message prepended with the configured default prefix (orecho:
if no prefix is configured).RESPOND TYPE=echo MSG="<message>"
: echo the message prepended withecho:
.RESPOND TYPE=echo_no_space MSG="<message>"
: echo the message prepended withecho:
without a space between prefix and message, helpful for compatibility with some octoprint plugins that expect very specific formatting.RESPOND TYPE=command MSG="<message>"
: echo the message prepended with//
. OctoPrint can be configured to respond to these messages (e.g.RESPOND TYPE=command MSG=action:pause
).RESPOND TYPE=error MSG="<message>"
: echo the message prepended with!!
.RESPOND PREFIX=<prefix> MSG="<message>"
: echo the message prepended with<prefix>
. (ThePREFIX
parameter will take priority over theTYPE
parameter)
[save_variables]¶
The following command is enabled if a save_variables config section has been enabled.
SAVE_VARIABLE¶
SAVE_VARIABLE VARIABLE=<name> VALUE=<value>
: Saves the variable to
disk so that it can be used across restarts. All stored variables are
loaded into the printer.save_variables.variables
dict at startup and
can be used in gcode macros. The provided VALUE is parsed as a Python
literal.
[screws_tilt_adjust]¶
The following commands are available when the screws_tilt_adjust config section is enabled (also see the manual level guide).
SCREWS_TILT_CALCULATE¶
SCREWS_TILT_CALCULATE [DIRECTION=CW|CCW] [MAX_DEVIATION=<value>]
[HORIZONTAL_MOVE_Z=<value>] [<probe_parameter>=<value>]
: This command will
invoke the bed screws adjustment tool. It will command the nozzle to different
locations (as defined in the config file) probing the z height and calculate
the number of knob turns to adjust the bed level. If DIRECTION is specified,
the knob turns will all be in the same direction, clockwise (CW) or
counterclockwise (CCW). See the PROBE command for details on the optional probe
parameters. IMPORTANT: You MUST always do a G28 before using this command. If
MAX_DEVIATION is specified, the command will raise a gcode error if any
difference in the screw height relative to the base screw height is greater
than the value provided. The optional HORIZONTAL_MOVE_Z
value overrides the
horizontal_move_z
option specified in the config file.
[sdcard_loop]¶
When the sdcard_loop config section is enabled, the following extended commands are available.
SDCARD_LOOP_BEGIN¶
SDCARD_LOOP_BEGIN COUNT=<count>
: Begin a looped section in the SD
print. A count of 0 indicates that the section should be looped
indefinitely.
SDCARD_LOOP_END¶
SDCARD_LOOP_END
: End a looped section in the SD print.
SDCARD_LOOP_DESIST¶
SDCARD_LOOP_DESIST
: Complete existing loops without further
iterations.
[servo]¶
The following commands are available when a servo config section is enabled.
SET_SERVO¶
SET_SERVO SERVO=config_name [ANGLE=<degrees> | WIDTH=<seconds>]
: Set
the servo position to the given angle (in degrees) or pulse width (in
seconds). Use WIDTH=0
to disable the servo output.
[skew_correction]¶
The following commands are available when the skew_correction config section is enabled (also see the Skew Correction guide).
SET_SKEW¶
SET_SKEW [XY=<ac_length,bd_length,ad_length>] [XZ=<ac,bd,ad>]
[YZ=<ac,bd,ad>] [CLEAR=<0|1>]
: Configures the [skew_correction]
module with measurements (in mm) taken from a calibration print. One
may enter measurements for any combination of planes, planes not
entered will retain their current value. If CLEAR=1
is entered then
all skew correction will be disabled.
GET_CURRENT_SKEW¶
GET_CURRENT_SKEW
: Reports the current printer skew for each plane in
both radians and degrees. The skew is calculated based on parameters
provided via the SET_SKEW
gcode.
CALC_MEASURED_SKEW¶
CALC_MEASURED_SKEW [AC=<ac_length>] [BD=<bd_length>]
[AD=<ad_length>]
: Calculates and reports the skew (in radians and
degrees) based on a measured print. This can be useful for determining
the printer's current skew after correction has been applied. It may
also be useful before correction is applied to determine if skew
correction is necessary. See Skew Correction for
details on skew calibration objects and measurements.
SKEW_PROFILE¶
SKEW_PROFILE [LOAD=<name>] [SAVE=<name>] [REMOVE=<name>]
: Profile
management for skew_correction. LOAD will restore skew state from the
profile matching the supplied name. SAVE will save the current skew
state to a profile matching the supplied name. Remove will delete the
profile matching the supplied name from persistent memory. Note that
after SAVE or REMOVE operations have been run the SAVE_CONFIG gcode
must be run to make the changes to persistent memory permanent.
[smart_effector]¶
Several commands are available when a smart_effector config section is enabled. Be sure to check the official documentation for the Smart Effector on the Duet3D Wiki before changing the Smart Effector parameters. Also check the probe calibration guide.
SET_SMART_EFFECTOR¶
SET_SMART_EFFECTOR [SENSITIVITY=<sensitivity>] [ACCEL=<accel>]
[RECOVERY_TIME=<time>]
: Set the Smart Effector parameters. When
SENSITIVITY
is specified, the respective value is written to the
SmartEffector EEPROM (requires control_pin
to be provided).
Acceptable <sensitivity>
values are 0..255, the default is 50. Lower
values require less nozzle contact force to trigger (but there is a
higher risk of false triggering due to vibrations during probing), and
higher values reduce false triggering (but require larger contact
force to trigger). Since the sensitivity is written to EEPROM, it is
preserved after the shutdown, and so it does not need to be configured
on every printer startup. ACCEL
and RECOVERY_TIME
allow to
override the corresponding parameters at run-time, see the
config section of Smart Effector
for more info on those parameters.
RESET_SMART_EFFECTOR¶
RESET_SMART_EFFECTOR
: Resets Smart Effector sensitivity to its factory
settings. Requires control_pin
to be provided in the config section.
[stepper_enable]¶
The stepper_enable module is automatically loaded.
SET_STEPPER_ENABLE¶
SET_STEPPER_ENABLE STEPPER=<config_name> ENABLE=[0|1]
: Enable or
disable only the given stepper. This is a diagnostic and debugging
tool and must be used with care. Disabling an axis motor does not
reset the homing information. Manually moving a disabled stepper may
cause the machine to operate the motor outside of safe limits. This
can lead to damage to axis components, hot ends, and print surface.
[temperature_fan]¶
The following command is available when a temperature_fan config section is enabled.
SET_TEMPERATURE_FAN_TARGET¶
SET_TEMPERATURE_FAN_TARGET temperature_fan=<temperature_fan_name>
[target=<target_temperature>] [min_speed=<min_speed>]
[max_speed=<max_speed>]
: Sets the target temperature for a
temperature_fan. If a target is not supplied, it is set to the
specified temperature in the config file. If speeds are not supplied,
no change is applied.
[tmcXXXX]¶
The following commands are available when any of the tmcXXXX config sections are enabled.
DUMP_TMC¶
DUMP_TMC STEPPER=<name> [REGISTER=<name>]
: This command will read all TMC
driver registers and report their values. If a REGISTER is provided, only
the specified register will be dumped.
INIT_TMC¶
INIT_TMC STEPPER=<name>
: This command will initialize the TMC
registers. Needed to re-enable the driver if power to the chip is
turned off then back on.
SET_TMC_CURRENT¶
SET_TMC_CURRENT STEPPER=<name> CURRENT=<amps> HOLDCURRENT=<amps>
:
This will adjust the run and hold currents of the TMC driver.
HOLDCURRENT
is not applicable to tmc2660 drivers.
When used on a driver which has the globalscaler
field (tmc5160 and tmc2240),
if StealthChop2 is used, the stepper must be held at standstill for >130ms so
that the driver executes the AT#1 calibration.
SET_TMC_FIELD¶
SET_TMC_FIELD STEPPER=<name> FIELD=<field> VALUE=<value> VELOCITY=<value>
:
This will alter the value of the specified register field of the TMC driver.
This command is intended for low-level diagnostics and debugging only
because changing the fields during run-time can lead to undesired and
potentially dangerous behavior of your printer. Permanent changes
should be made using the printer configuration file instead. No sanity
checks are performed for the given values.
A VELOCITY can also be specified instead of a VALUE. This velocity is
converted to the 20bit TSTEP based value representation. Only use the VELOCITY
argument for fields that represent velocities.
[toolhead]¶
The toolhead module is automatically loaded.
SET_VELOCITY_LIMIT¶
SET_VELOCITY_LIMIT [VELOCITY=<value>] [ACCEL=<value>]
[MINIMUM_CRUISE_RATIO=<value>] [SQUARE_CORNER_VELOCITY=<value>]
: This
command can alter the velocity limits that were specified in the
printer config file. See the
printer config section for a
description of each parameter.
[tuning_tower]¶
The tuning_tower module is automatically loaded.
TUNING_TOWER¶
TUNING_TOWER COMMAND=<command> PARAMETER=<name> START=<value>
[SKIP=<value>] [FACTOR=<value> [BAND=<value>]] | [STEP_DELTA=<value>
STEP_HEIGHT=<value>]
: A tool for tuning a parameter on each Z height
during a print. The tool will run the given COMMAND
with the given
PARAMETER
assigned to a value that varies with Z
according to a
formula. Use FACTOR
if you will use a ruler or calipers to measure
the Z height of the optimum value, or STEP_DELTA
and STEP_HEIGHT
if the tuning tower model has bands of discrete values as is common
with temperature towers. If SKIP=<value>
is specified, the tuning
process doesn't begin until Z height <value>
is reached, and below
that the value will be set to START
; in this case, the z_height
used in the formulas below is actually max(z - skip, 0)
. There are
three possible combinations of options:
FACTOR
: The value changes at a rate offactor
per millimeter. The formula used is:value = start + factor * z_height
. You can plug the optimum Z height directly into the formula to determine the optimum parameter value.FACTOR
andBAND
: The value changes at an average rate offactor
per millimeter, but in discrete bands where the adjustment will only be made everyBAND
millimeters of Z height. The formula used is:value = start + factor * ((floor(z_height / band) + .5) * band)
.STEP_DELTA
andSTEP_HEIGHT
: The value changes bySTEP_DELTA
everySTEP_HEIGHT
millimeters. The formula used is:value = start + step_delta * floor(z_height / step_height)
. You can simply count bands or read tuning tower labels to determine the optimum value.
[virtual_sdcard]¶
Klipper supports the following standard G-Code commands if the virtual_sdcard config section is enabled:
- List SD card:
M20
- Initialize SD card:
M21
- Select SD file:
M23 <filename>
- Start/resume SD print:
M24
- Pause SD print:
M25
- Set SD position:
M26 S<offset>
- Report SD print status:
M27
In addition, the following extended commands are available when the "virtual_sdcard" config section is enabled.
SDCARD_PRINT_FILE¶
SDCARD_PRINT_FILE FILENAME=<filename>
: Load a file and start SD
print.
SDCARD_RESET_FILE¶
SDCARD_RESET_FILE
: Unload file and clear SD state.
[z_thermal_adjust]¶
The following commands are available when the z_thermal_adjust config section is enabled.
SET_Z_THERMAL_ADJUST¶
SET_Z_THERMAL_ADJUST [ENABLE=<0:1>] [TEMP_COEFF=<value>] [REF_TEMP=<value>]
:
Enable or disable the Z thermal adjustment with ENABLE
. Disabling does not
remove any adjustment already applied, but will freeze the current adjustment
value - this prevents potentially unsafe downward Z movement. Re-enabling can
potentially cause upward tool movement as the adjustment is updated and applied.
TEMP_COEFF
allows run-time tuning of the adjustment temperature coefficient
(i.e. the TEMP_COEFF
config parameter). TEMP_COEFF
values are not saved to
the config. REF_TEMP
manually overrides the reference temperature typically
set during homing (for use in e.g. non-standard homing routines) - will be reset
automatically upon homing.
[z_tilt]¶
The following commands are available when the z_tilt config section is enabled.
Z_TILT_ADJUST¶
Z_TILT_ADJUST [HORIZONTAL_MOVE_Z=<value>] [<probe_parameter>=<value>]
: This
command will probe the points specified in the config and then make independent
adjustments to each Z stepper to compensate for tilt. See the PROBE command for
details on the optional probe parameters. The optional HORIZONTAL_MOVE_Z
value overrides the horizontal_move_z
option specified in the config file.
[temperature_probe]¶
The following commands are available when a temperature_probe config section is enabled.
TEMPERATURE_PROBE_CALIBRATE¶
TEMPERATURE_PROBE_CALIBRATE [PROBE=<probe name>] [TARGET=<value>] [STEP=<value>]
:
Initiates probe drift calibration for eddy current based probes. The TARGET
is a target temperature for the last sample. When the temperature recorded
during a sample exceeds the TARGET
calibration will complete. The STEP
parameter sets temperature delta (in C) between samples. After a sample has
been taken, this delta is used to schedule a call to TEMPERATURE_PROBE_NEXT
.
The default STEP
is 2.
TEMPERATURE_PROBE_NEXT¶
TEMPERATURE_PROBE_NEXT
: After calibration has started this command is run to
take the next sample. It is automatically scheduled to run when the delta
specified by STEP
has been reached, however its also possible to manually run
this command to force a new sample. This command is only available during
calibration.
TEMPERATURE_PROBE_COMPLETE:¶
TEMPERATURE_PROBE_COMPLETE
: Can be used to end calibration and save the
current result before the TARGET
temperature is reached. This command
is only available during calibration.
ABORT¶
ABORT
: Aborts the calibration process, discarding the current results.
This command is only available during drift calibration.
TEMPERATURE_PROBE_ENABLE¶
TEMPERATURE_PROBE_ENABLE ENABLE=[0|1]
: Sets temperature drift
compensation on or off. If ENABLE is set to 0, drift compensation
will be disabled, if set to 1 it is enabled.
