Filament Runout sensor 1.75

14.96 incl. BTW


Product Description

With this sensor it is possible for the 3D printer to detect when the filament has run out, so that it can pause and wait to switch to a new roll of filament, for example. Mechanically, it is a microswitch in a plastic housing (factory-made), with a channel to feed your filament. With this sensor you no longer have to worry about your filament running out.

Code for marlin:

  #define FIL_RUNOUT_INVERTING false // set to true to invert the logic of the sensor.
  #define ENDSTOPPULLUP_FIL_RUNOUT // Uncomment to use internal pullup for filament runout pins if the sensor is defined.

For more information and to configure the runout sensor in marlin. See link.
