Product Introduction

FilGuard Filament detector is compatible with VZ-Hextrudort-Low extruder, supports filament breakage detection, clogging detection, and comes with customizable buttons.

Wiring Tutorial​

  • On-board PH2.0 5P terminal makes wiring more convenient

Firmware Light Status Introduction​

  • Out of filament: Red flashing
  • Feeding: Blue flashing (the faster the feeding speed, the higher the flashing frequency)
  • Retracting: Green flashing (same as above)
  • Filament present but no feeding or retracting: Orange breathing light

Klipper, filament breakage and clogging reference configuration​

warning

In the clogging detection configuration, detection_length: 2.0

2.0mm is the minimum detection length required for the normal operation of this smart consumable detection module. If you encounter false triggering issues, try increasing the detection length by 1 mm until the problem is resolved.
