Hello guys
As promised
I did a remake of my old filament sensor because there were to many parts, and it was heavy.

So this sensor detects jams in the hotend also running out of filament.
It uses a sensor and an arduino

How does it work?

- filaments spins the toothed wheel in the sensor, the sensor goes high to low and vice versa. The arduino calculates if the time between HIGH and LOW is between the programmed time, if not the arduino pin will go high and sends a signal to your buzzer
(more info in the arduino sketch)


Use dark plastic for the toothed filament roller, i noticed if you use light plastic the sensor readings where not reliable, so i covered the tooth with paint...
if the filament slips use double sided tape in the toothed roller, i
