Duet Laser Filament Monitor


Limited stock remaining. Currently shipping v2.0.

The Duet3D Laser Filament Monitor uses a IR laser optical motion detector to  detect filament movement. The detected movement is transmitted to the Duet 2 Wifi, Duet 2 Ethernet or Duet 2 Maestro which uses the indicated movement to determine if the filament has run out, jammed or been ground away in the extruder. It is available for 1.75mm diameter filament only.

The monitor PCB comes with two Molex KK-style 3 way plugs and pins, along with ~60mm of Capricorn XS Ultra Low Friction PTFE tubing to act as the filament guide. The 3D-printed enclosure and M3 mounting bolts are not included. Please see the documentation for more information:  Documentation for the Duet3D Laser Filament Monitor.
