Filament runout sensor for 1.75mm filament diameter. Use the digital output of the sensor.
May also be used as a filamentwidth sensor if you use the analogue output, but haven´t tested that yet.
To adjust the sensivity ( distance and or strenght of magnet to sensor ) use the trimpot.
Additional Parts required:
