If your printer is moving but nothing is coming out or the printer is making a clicking sound on the filament.


It is most likely that you have a build up of plastic dust inside the print head.


Please watch this video to see how to clean the extruder hear gear.

This build up of dust around the gear can be caused by the following:

  • The gap between the platform and the nozzle is not at an equal distance in all four corners of the platform, thus causing lifting, which in turn obstructs the material coming out and thus 

the drive gear eats into the filament and produces dust around the gear.

  • The gap between the platform and the nozzle is too close, thus obstructing the plastic from coming out, thus the drive gear eats into the filament and produces dust around the gear.
