Fiber Extruder Replacement


Topics:


Supplies:

  • 2mm hex key
  • 2.5mm hex key

 

Remove the Fiber Extruder

Note: Take care not to discard any hardware you remove during this procedure, as you will need it during the reinstallation.

  1. Completely unload all print material. For more information, see Unload Plastic and Unload Fiber.
  2. Cool the print head (Menu > Utilities > Manual Control > Temperature Control > Cool).
    Note: The print head may take several minutes to completely cool.
  3. Power off your printer and manually move the print head away from the extruders.
  4. Using the 2mm hex key, slightly unscrew the top left socket head cap screw on the fiber extruder.
    Note: Do not unscrew it all the way. It should require no more than one full turn to loosen.



  5. Remove the fiber Bowden tube from the extruder.
  6. Using the 2mm hex key, slightly unscrew the top right socket head cap screw on the fiber extruder.
    Note: Do not unscrew it all the way. It should require not more than one full turn to loosen.
  7. Remove the fiber feed tube from the extruder. Let it hang freely.
  8. Using the 2.5mm hex key, loosen the four screws that secure the fiber extruder to the printer chassis.
    Note: The bracket on the extruder has keyhole slots that enable the extruder to slide out without the screws being removed.

    Note: You may need to use pliers to remove the 4-wire connector. Be careful not to let the base of the extruder sever the wires.
  11. Remove the fiber extruder.

Reinstall the Fiber Extruder

  1. Insert the 3-wire and 4-wire connectors into the corresponding ports on the new fiber extruder and ensure that they are plugged in all the way.
  2. Seat the new fiber extruder on the printer chassis such that the keyhole slots on the extruder bracket align with the screws.
  3. Tighten the four screws that connect the base of the extruder to the chassis.
  4. Securely insert the fiber Bowden tube into the front of the fiber extruder and tighten the top left screw.
  5. Securely insert the fiber feed tube into the back of the extruder and tighten the top right screw.
  6. Power on your printer.
  7. Reload materials. For more information, see Load Plastic and Load Fiber.
