Removing the Plastic Extruder

To remove the Plastic Extruder on your printer:

  1. Unload plastic and fiber filament. (for instructions, click here for plastic, and here for fiber)
  2. Allow your print head to cool down.

    Note: The print head will take about five to seven minutes to completely cool.

  3. Turn off your printer, and manually move the print head away from the extruders.
  4. Use a 2mm Allen wrench to loosen the top left set screw on the Fiber Extruder front plate.

  5. 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.

  6. Unscrew the thumb screw that connects the Plastic Bowden Tube to the Plastic Extruder.

  7. Remove the Plastic Bowden Tube from the Plastic Extruder and let it hang freely.

  8. Use a 2.5mm Allen wrench to remove the bolts that attach the Plastic Extruder to the printer chassis.

  9. 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.

  10. 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.
