When the H2D is used with a single AMS 2 Pro, all functions, including automatic feeding and drying, can be utilized without an external power adapter.
When the H2D is used with more than one AMS 2 Pro, if some AMS 2 Pro units are used for multi-color printing while others are used for filament drying, then the AMS 2 Pro units used for drying require an external power adapter. The external power adapter can be purchased from the Bambu Lab official store.
X1 Series and P1 Series are compatible with AMS 2 Pro. If only using the automatic filament feeding function, only the 6-pin bus cable, 4-pin bus cable and Filament Buffer/AMS Hub are required, and no external power adapter is needed. However, if you need to use the drying function, an external power adapter is required for the AMS 2 Pro.
Note: Be sure to use the new 6-pin cable included with AMS 2 Pro and AMS HT. Using the 6-pin cable from the previous generation AMS may cause unstable communication between the AMS and the printer, while the previous generation AMS is compatible with the new 6-pin cable.
All the accessories can be purchased in the upgrade kit of the AMS 2 Pro add-on section.
If you previously purchased the X1/P1 standalone unit (without AMS), in addition to the accessories mentioned above, you will also need to buy a pneumatic connector.
The AMS 2 Pro is compatible with X1/P1 series printers for multi-material printing. The filament drying feature for these older generation machines will be fulfilled through an OTA update by the end of April.
AMS 2 Pro compatibility with A1/A1 mini printers will be added through an OTA update in Q3 2025.

Yes, you can use both AMS and AMS 2 Pro on one H2D.
Currently, drying is not supported for AMS 2 Pro/HT that are actively involved in the printing process, including those that may be used for automatic refill during the current print job. Printing while drying is not yet supported.
The only "dry while print" scenario currently supported is: the printer uses some of the connected AMS 2 Pro/HT units or an external spool holder for printing, while the AMS 2 Pro/HT units not involved in the current print job can be used for drying.
If the printer is feeding or printing, and at the same time powering 1 AMS 2 pro for drying, the drying power will be automatically reduced, in order to ensure that the printing power is prioritized. So it is recommend to use the external power adapter for best drying results.
The H2D printer supports powering one AMS 2 Pro for drying directly from the printer. If you need to dry filament in multiple AMS 2 Pro units simultaneously, the additional AMS 2 Pro units require power supply via a power adapter (purchased separately).
When using the AMS 2 Pro drying function, the AMS 2 Pro must be connected to the printer via a 6-pin bus cable to ensure that the printer is powered on and set to filament drying mode.
The AMS 2 Pro cannot perform standalone drying without a connection to the printer.
Please use the 6-pin cable for AMS 2 Pro and AMS HT. The cable for the previous generation of AMS is not compatible with AMS 2 Pro.
The port at the rear of the top cover is specifically for TPU filament. Due to the softness of the TPU filament, it is easy to fail when using the AMS 2 Pro automatic feeding function. When using the TPU, insert it into the AMS HT and ensure the material tray rotates in the correct direction. Insert the material tube into the TPU bypass port and manually push the filament through the PTFE tube until it is fully loaded into the extruder.
Note:
When using TPU, AMS HT cannot use the automatic feed and return function, but can be used as a drying box to prevent material moisture.
AMS HT won't be able to run filament drying while feeding filament and initiating a print via the bypass port.
AMS HT compatibility with X1 and P1 printers will be added through an OTA update by the end of April.
If only connecting one AMS HT to a X or P series printer, a filament buffer is required to be purchased separately. If connecting multiple AMS HT units,we recommend that you purchase an AMS Hub.
AMS HT compatibility with A1 and A1 mini printers will be added through an OTA update in Q3 2025.
Printing while drying is not yet supported, including all the AMSs that are related to the on-going print job (eg. The AMSs assigned for auto-refill). However, you can dry filament in AMSs that are not assigned to the on-going print job.
X1 and P1 series printers support up to 4 AMS HT connections at the same time.
H2D and X/P/A series printers are connected to AMS HT and use drying function. Each AMS HT requires an external 220V power supply for drying It is not supported to draw power from the printer for drying (The power adapter is pre-included with the product package).
When using the AMS HT drying function, the AMS HT must be connected to the printer via a 6-pin bus cable to ensure that the printer is powered on and set to filament drying mode.
The AMS HT cannot perform standalone drying without a connection to the printer.
Please use the 6-pin cable for AMS 2 Pro and AMS HT. The cable for the previous generation of AMS is not compatible with AMS HT.
