Cleaning the extruder drive gear
Extruder is located inside the printer chamber, upper right corner.
The design of the extruder allows cleaning of the drive gear
without disassembling it. Use hard brush or plastic tip to remove
any stuck plastic from the drive gear. The drive gear teeth can
sometimes become filled with plastic parts from filament, when
the print head has been clogged and the drive gear has "dug"
into the filament.
Replacing the extruder drive gear
Drive gear can be replaced without disassembling the extruder.
Remove the filament first. Then turn the gear by hand so the
fixing nut is visible and loosen it. The gear should come off.
