Replacing the Print Head

To replace the print head on your printer:

  1. Carefully place the new print head onto the print head base. Be careful to align the pins on the print head base with the holes on the print head so that the pins are not damaged.

  2. Use a 2.5mm Allen wrench to tighten the two bolts that connect the print head to the print head base.

  3. Reconnect the Axon cable and the Axon cable clip.
    Note: Be careful not to break the cable, clip, or board. Be sure the cable is secure. The clip will keep the cable from dragging on parts or becoming damaged.
  4. Replace the Bowden Tubes for both materials and tighten the thumb screws into the print head.
  5. Turn your printer on.
  6. Reload plastic and fiber material into your printer.
  7. Run the Adjust Laser Offsets utility (Menu > Utilities > Print Head Alignment > Laser-Guided Offsets).
