Overview If you need to dry the filaments in more than one AMS 2 Pro at the same time, you will need to use the Bambu Lab official Switching Adapter to power the additional AMS 2 Pro. If the X1, P1, A1 series printer is used with the AMS 2 Pro and uses the AMS 2 Pro's drying function, each AMS 2 Pro requires an official Bambu Lab Switching Adapter to power it. For H2D Printer: Connecting a Single AMS 2 Pro: A single AMS 2 Pro can be powered and dried by the H2D printer directly, no additional Switching Adapter is required. Connecting multiple AMS 2 Pro units together: If the drying function is enabled for multiple units, each AMS 2 Pro requires its own Switching Adapter. Even if only one unit is drying, the system power may automatically reduce, leading to insufficient drying. It is recommended to use a power adapter to ensure optimal drying performance. For X1/P1 Series Printer: Drying Function Requirement: A power adapter must be used when enabling the drying function to ensure sufficient power. Connecting multiple AMS 2 Pro units together: If the drying function is enabled for multiple units, each AMS 2 Pro requires its own Switching Adapter. Non-Drying Function Use: The Switching Adapter can be omitted if the drying function is not used. Notes: The AMS 2 Pro is compatible with X1/P1 series printers for multi-material printing.
