Introduction
What you need
Step 1
Remove Fan Cover
- Remove the 3D printed plastic cover by lifting up and to the left. The latches in the back should lift right out, however this can be tricky since the 3D printed connections don’t always sit in place well.

Step 3
Removing the Filament
- Set up the printer as you would use it normally by connecting the USB cable from the rear of the printer to your computer and then turning it on.
- Once connected to your computer bring up the included up software and click 3D print at the top and select Maintenance. Under the new maintenance window, click withdraw.
- Wait for the printer to beep to indicate it has fully withdrawn the plastic before you remove the remaining end from the extruder assembly.

Step 4
Remove Extrusion Assembly
- Unscrew the 3mm hex screw, on the underside immediately behind the nozzle heater that holds the entire extrusion assembly in place.
- Be careful when unscrewing this as there are two small flat washers that can easily fall off. Be mindful that unscrewing this screw will mean that the entire extrusion assembly can come free of the printer body.

Step 5
Remove Connectors
- Disconnect the three and four pin connectors on the top of the extruder assembly by gently wiggling the connectors side to side until they become loose and pull out.
- These connectors are designed to latch in once in place, so they may be hard to remove.

Step 9
Clean The Stepper Motor Gear
- Clean the stepper motor gear by brushing it with a fine stiff brush and ensure that all of the plastic remnants and dust have been removed.
- If needed, use q-tips dipped in rubbing alcohol (higher percentage the better) to swab out the remaining particles left over.
