TSL1401CL filament width sensor¶
This document describes Filament Width Sensor host module. Hardware used for developing this host module is based on TSL1401CL linear sensor array but it can work with any sensor array that has analog output. You can find designs at Thingiverse.
How does it work?¶
Sensor generates analog output based on calculated filament width. Output voltage always equals to detected filament width (Ex. 1.65v, 1.70v, 3.0v). Host module monitors voltage changes and adjusts extrusion multiplier.
Sensor readings done with 10 mm intervals by default. If necessary you are free to change this setting by editing MEASUREMENT_INTERVAL_MM parameter in filament_width_sensor.py file.
