Description

PDF

The stock runout sensor that uses a spring and some bearings got too much resistance, and limited my extruding capability! so I made this optical version, that's smoother, lined to the teeth with ptfe tubing

Very “clear” shortcoming includes: not able to detect clear (pun intended) filaments in it's path

Features:
- 4 Different variants for wide variety of couplers
- 2 LED output paths to be able to see the indicator, everywhere!
- Lined with ptfe for as smooth of a filament path as possible
- Uses a widely available optical endstop sensor

NOTE:
- Not able to detect clear filaments
- For neptune users, you have to cross the 2 outer wires for it to work
- For other users, the pinout is written on the pcb, wire after it
