Cleaning the feeder

After a lot of printing, the knurled wheel in the material feeder can accumulate small plastic particles. The knurled wheel can easily be taken out and cleaned in the following way.

  • Remove the filament from the Ultimaker Original.
  • Open up the feeder by loosening the lever and pulling out the black plastic part.
  • Remove the feeder bolt clip (the black clip that keeps the knurled wheel in place).

  • Take out the extruder gear with the knurled wheel attached to it and simply remove the dust by blowing some air against it or using a brush.
  • To re-assemble the knurled wheel, reverse the previous steps.
