BASIC MAINTENANCE
Changing Filament
Changing filament from one material to another is as easy as inserting filament as seen
above in the Inserting Filament into Extruder section. !
1. Make sure your extruder is heated to the
extruding temperature when changing
filaments. !
2. Once your new filament is inserted into the
extruder, manually push the filament through
the extruder to observe filament being
extruded from the heated nozzle. !
3. Close the Filament Drive Door and turn the
Drive Door Lock Knob clockwise until its
tight. !
Filament Gear
The filament drive gear teeth is what feeds the extruder while printing. You may find that
using a low quality filament or through rigorous retractions and extractions, your filament can
get degraded by the gear teeth and will stop extruding. If you find this is the cause of your
print failure, follow the following steps:!
1. Open the filament drive door to get to the filament gear. !
2. Remove the top filament portion (coming from the filament spool).!
3. Make sure your nozzle is heated to the extrusion temperature of your filament.!
4. Using tweezers from your tool kit, gently wiggle out the filament upwards and through
the open filament drive door. !
5. Clean out the filament drive gear teeth with pressurized air or simply by blowing out the
ground filament.!
The filament drive gear requires very little maintenance other than regularly removing any
filament particles inside the gear housing with a light blast of air. !
