How do I fix ams filament tangled / spool stuck?

  1. 1

    Open the AMS and check for filament tangles. If filament crossed over itself on the spool, carefully unwind and re-spool it.

  2. 2

    Inspect PTFE tubes inside the AMS for kinks, wear, or debris. Replace worn tubes and blow out debris with compressed air.

  3. 3

    Check the AMS assist motor gear for jammed filament fragments. Manually feed filament through to verify the path is clear, then click "Retry".

Pro tip: AMS feed issues waste print time. Ensure filament is properly wound on spools and PTFE tubes are in good condition.
