Jam in Nozzle or Print Head




Clearing the Fiber Nozzle

From time to time the fiber nozzle on your printer can occasionally get clogged. This is especially common after a failed print.

In the event that your fiber nozzle appears to be clogged, remove the nozzle and check to see if the PTFE tube is clogged. If it is clogged, replace the PTFE tube and reinstall the nozzle; this will fix a majority of clogged nozzle issues. If the PTFE tube is not clogged, continue to the steps below. For more information about removing and replacing the nozzle or PTFE tube, please see Replacing the Fiber Nozzle.

To clear a Fiber Jam on your print head:

  1. Select the Menu from the upper right corner of the printer's touch screen.

  2. Select the "Utilities" tile from the available options.

  3. Select the "Manual Control" tile from the available options. 

  4. Select the "Temperature Control" tile from the available options.

  5. Select the "Heat" option on the screen when prompted.

  6. Select the "Fiber Nozzle" option on the screen when prompted.

  7. Press the "Done" icon to exit from the manual heating utility.

  8. Remove the thumb screw that connects the Fiber Bowden tube to the print head.

  9. Look down through the print head channel to see if there is any blockage; if so, cool the print head and remove the nozzle to check the following:
    1. Attempt to pull any fiber strands from the PTFE tube and nozzle; if the fiber blockage cannot be pulled free, replace the blocked component.
      Note: If only the PTFE tube is blocked, you can just replace that without needing to replace the nozzle.
    2. With the Bowden Tube and Nozzle removed, check the print head channel again to see if there is blockage. If so, please Contact Support before trying to remove the fiber or continuing with any troubleshooting steps.
  10. Replace the nozzle and Bowden tube and run the "Load Fiber" routine to confirm that fiber can be loaded through the nozzle.
    Note: If you have confirmed that everything is cleared but fiber still can't be loaded, please Contact Support.
