About the Filament Buffer – P2S
The filament buffer for the Bambu Lab P2S (Bambu Lab part SA011). Its function is to provide a buffering effect for the filament between the AMS and the printer. Bambu Lab: “To connect one or two AMS 2 Pro unit(s) to P2S, a P2S Filament Buffer (SA011) is required” and “The standalone P2S (without AMS) does not include a filament buffer.” The P2S Combo already includes one, so you only need this part when you add an AMS or AMS 2 Pro to a P2S bought without one.
Key Features
- Fits the Bambu Lab P2S only
- Required to connect an AMS or AMS 2 Pro to a standalone P2S; Bambu Lab also lists a Bambu Bus Cable (CAB035) for that connection
- Included in the P2S Combo
