Fiber Jam Detection


Topics:

 

Supplies:

  • 10mm torque wrench
  • Tweezers

 

Note that the print head is factory-calibrated; do NOT adjust or disassemble in any way unless specifically instructed to do so by Markforged Support. Warranty claims for assemblies that have been adjusted, disassembled, or modified may not be honored.

 

Automatic fiber jam detection is enabled by default. We recommend that you enable fiber jam detection so that, in the event of a fiber jam, your printer will be able to prompt you to take appropriate action.

 

Enable / Disable Fiber Jam Detection 

  1. Select the menu icon from the dashboard.



  2. Select the Settings tile from the available options.



  3. Select the System Info tile from the available options.



  4. Select the gears icon from the row of icons at the bottom of the screen.

Detect and Debug Fiber Jams

In the event of a suspected fiber jam, your printer will stop the print to allow you to resolve the issue. Once a jam is detected and corrected, the print can resume from where it stopped.

    1. Select Debug Jam button on the touchscreen.



    2. Clear any excess fiber from the nozzle and ensure that the print bed has clearance to lower completely, then press Next.



    3. Wait for the nozzles to cool completely.



    4. Use the 10mm torque wrench to unscrew the fiber nozzle and check the nozzle for any obstructions, then press Next to continue debugging.



    5. Remove the fiber Bowden tube from the print head and verify that there are no obstructions in the print head’s fiber nozzle channel, then press Next to continue debugging.



    6. Verify that the material on the fiber spool is neither tangled nor becoming unspooled, then press Next to continue debugging.



    7. Verify that the fiber is not caught in the Bowden tube and press Next.



    8. Ensure that there is nothing in the way of the print bed and print head returning to their pause positions.
      Note: You should always remove foreign objects from the print chamber before initiating a print job.



    9. Follow the onscreen prompts to return to the pause screen on your printer.

Ensure that you reinstall any components you removed during this procedure before attempting to print.
