How to Fix AMS Cutter Stuck / Failed to Cut

Step-by-step fix for ams cutter stuck / failed to cut on Bambu Lab printers including X1C, H2D, P1S, and A1.

How do I fix ams cutter stuck / failed to cut?

  1. 1

    Pull the cutter handle out manually — it may be stuck with filament debris. Gently pull it outward until it clicks back.

  2. 2

    Clean the cutter blade area with compressed air. Filament strands accumulate around the blade over time, especially with CF/GF materials.

  3. 3

    If the cutter repeatedly fails with TPU: consider bypassing the AMS and feeding from the spool holder instead.

Pro tip: A stuck cutter halts multi-material prints. Keep the cutter clean as part of regular maintenance.
