Replace the Print Head

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

     

  2. While supporting the print head with your hand, use the 2.5mm hex key to tighten the two screws that connect the print head to the print head base.



  3. Reinsert the ribbon cable into its connector until both tabs snap into place, then slide the cable clip back onto its bracket.
    Note: Be careful not to break the cable, clip, or board. Ensure that the cable is secure. The clip will keep the cable from dragging on parts or becoming damaged.
  4. Reinstall both Bowden tubes and tighten the respective thumbscrews into the print head.
  5. Power on your printer.
  6. Reload print material into your printer. For more information, see Load Plastic and Load Fiber, if applicable.
  7. Plug the provided USB drive (see Supplies, above) into your printer.
  8. Select the menu icon from the dashboard.

  9. Select the Storage tile from the menu options.
