Bambu Lab Filament Cutter Lever - P2S

The Bambu Lab Filament Cutter Lever – P2S is a genuine OEM replacement for the filament-cutting mechanism inside the P2S toolhead. The lever operates the cutter blade directly above the hotend, allowing loaded filament to be cleanly severed before the printer retracts the old material and feeds new filament.

Reliable filament cutting is particularly important when using an AMS or performing automatic material changes, because the filament must be properly cut before it can be withdrawn from the toolhead. A damaged, worn, sticking, or incorrectly operating cutter lever can result in incomplete cuts, failed unloading, filament jams, or interrupted material changes.

The FAC168 replacement restores the correct cutter-lever geometry and actuation for the Bambu Lab P2S. Replace the lever if it is physically damaged, no longer moves freely, or cannot reliably actuate the filament cutter.
