Rotating Magnet Filament Monitor The Duet3D Rotating Magnet Filament Monitor very accurately senses filament movement. Connect it to a Duet 2 Wifi, Ethernet or Maestro and the controller will use the indicated movement to determine a wide range of extrusion issues including: • Filament run out
• Extruder skipping stepps
• Nozzle starting to jam (causing skipped steps or grinding)
• Filament beginning to grind in the extruder

It does this so accurately because it is effectively an extruder in reverse. The filament movement rotates a custom machined hobbed magnet assembly; the magent rotation is sensed and constantly reported to the Duet.This method has proven extremely accurate across a wide range of filaments – frequently capable of pausing the print before a filament jam or other issue has already caused the print to fail.
