What it is

This is a nozzle switch, so that you can easily switch your AMS between the left and right nozzle. This is easier and more convenient than swapping the filaments in the AMS. After switching, briefly run the automatic AMS setup and printing can begin.

The assembly does not require any screws or other additional parts, only the ptfe tubes and “Bambu 4-in-1 PTFE Adapter” or your prefered y-pieces.

NEW!! Buildplate 5 has a parts where you can fit in PC4-M6 Pneumatic Connector for PTFE Tube 

The nozzle switch is attached to the mounting piece of the external spool.

AMS labeling
