Does the AMS 2 Pro Work With the Bambu Lab A1 and A1 Mini? Compatibility Rules
Bambu Lab’s multi-model connection guide lists an A-series connection path, but warns that you must NEVER use the standard X1/P1 filament buffer or AMS Hub on an A-series printer—doing so damages the buffer or hub and voids the warranty. You must use the A1 dedicated AMS Hub and check your exact printer model’s firmware notes before buying. Last checked October 25, 2026.
Owners of the Bambu Lab A1 and A1 Mini (which normally use the open-frame AMS Lite) frequently ask whether they can upgrade to the enclosed, heated AMS 2 Pro. This guide collects what Bambu Lab’s official compatibility wiki states as of October 25, 2026, without guessing where documentation is incomplete.
What Bambu Lab’s wiki states about A-series printers
| Topic | What Bambu’s Wiki Says | Source |
|---|---|---|
| A-Series Connection Listing | The AMS 2 Pro Part Introduction and Multi-Model Compatibility guides include a section titled “Connect the AMS 2 Pro to A1 series printers” and list A2L (v01.01.00.00+) in the firmware table. | Intro Guide, Multi-Model Guide |
| Buffer / Hub Hardware Warning | Do not use the filament buffer or AMS Hub designed for X1/P1 printers to connect an A-series printer. It can cause the buffer or hub to malfunction or become damaged, voiding the warranty. | Multi-Model Guide |
| Required Hub for A1 Series | Bambu states: “Please use the A1 dedicated AMS Hub to connect the AMS.” | Multi-Model Guide |
| 6-Pin Cable Requirement | Always use the new-version 6-pin cable (2.5 mm step height) included with the AMS 2 Pro. | Multi-Model Guide |
Critical hardware warning: X1/P1 Buffer vs. A1 Dedicated Hub
If you buy AMS 2 Pro Upgrade Kit 1 or Upgrade Kit 2, those kits are built for the X1 and P1 series and contain the standard filament buffer or standard AMS Hub. Bambu Lab’s multi-model compatibility guide issues a direct warning:
- Plugging the standard filament buffer or standard AMS Hub into an A-series printer can electrically or mechanically damage the unit.
- Damage caused by using the wrong hub on an A-series printer is excluded from warranty coverage.
- Only the A1 dedicated AMS Hub should be used when bridging enclosed AMS units to supported A-series machines.
What about the AMS Lite vs. AMS 2 Pro?
- AMS Lite: Open-frame 4-spool feeder designed specifically for the A1 and A1 Mini; has no enclosure and no active heater.
- AMS 2 Pro: Enclosed 4-spool unit with a 65 °C active heater, electromagnetic air vents, and brushless feeding motor; requires a 24V 4A Switching Adapter for drying if the host printer cannot supply drying power over the bus cable.
What is not confirmed yet
Bambu Lab’s public store listings vary by region on whether both the original A1 and A1 Mini have received stable consumer firmware for full AMS 2 Pro drying menu control, or if full integration is rolling out via phased firmware updates (the FAQ explicitly lists firmware version 01.01.00.00 for the A2L and notes “Other printers will receive the feature in future updates”). Check your specific A1 or A1 Mini firmware release notes before ordering.
