Goals:
Removing the Plastic Extruder
To remove the Plastic Extruder on your printer:
- Unload plastic and fiber filament. (for instructions, click here for plastic, and here for fiber)
- Allow your print head to cool down.
Note: The print head will take about five to seven minutes to completely cool.
- Turn off your printer, and manually move the print head away from the extruders.
- Use a 2mm Allen wrench to loosen the top left set screw on the Fiber Extruder front plate.
- Remove the Fiber Feed Tube inlet from the Fiber Extruder and slide the Fiber Feed Tube out of the channel through the bottom of the Plastic Extruder.
- Unscrew the thumb screw that connects the Plastic Bowden Tube to the Plastic Extruder.
- Remove the Plastic Bowden Tube from the Plastic Extruder and let it hang freely.
- Use a 2.5mm Allen wrench to remove the bolts that attach the Plastic Extruder to the printer chassis.
- Carefully pull the large connector from behind the stepper motor next to the Plastic Extruder. After it is accessible, disconnect the clip by pressing on the indicated area.
Note: Do not pull on the wires, only pull on the white clips.
- Disconnect both wire clips behind the extruder. A tweezer may be used to help snag the connector out.
Note: Do not pull on the wires, only pull on the white clips.
- Remove the Plastic Extruder from the printer.
Reinstalling the Plastic Extruder
- Place the new Plastic Extruder in the printer.
- Re-attach the three white wire clips onto the Plastic Extruder and the connection on the left of the extruder.
- Place the screws in the holes to secure the extruder on the printer chassis.
- Slide the Fiber Feed Tube through the channel at the bottom of the Plastic Extruder towards the Fiber Extruder.
- Slide the metal inlet on the Fiber Feed Tube into the V-shaped groove on the left side of the Fiber Extruder. Using 2mm Allen wrench, tighten the set screw until the metal inlet is secured but not flattened
Note: Make sure the metal inlet is slid all the way in, and pressed against the Fiber Extruder.
- Reinstall the Plastic Bowden Tube in the Plastic Extruder and tighten the thumb screw.
- Turn on the printer and reload materials.
