AMS 2 Pro flashing 4 red lights on A1 with AMS Hub, but AMS Lite works fine?
Hi all,
I’m hoping someone has either seen this before or has some ideas, because I’m deep into troubleshooting territory now 😅
I have a Bambu A1 and an AMS 2 Pro. The AMS 2 Pro keeps flashing 4 red lights and won’t connect properly when using the AMS Hub for A1.
What’s confusing is:
• My AMS Lite works perfectly fine on the same A1
• The printer itself works fine
• If I use the AMS Filament Buffer from my P1S instead of the A1 AMS Hub, the A1 prints perfectly with the AMS 2 Pro
• As soon as I go back to the AMS Hub setup, the AMS 2 Pro flashes red again
I’ve also tested the AMS 2 Pro on my Dad’s A1 and it does exactly the same thing there too.
So far with Bambu support I’ve replaced:
• AMS interface board
• 4-pin cable
• A1 mainboard
• AMS Hub
At this point it feels like the AMS 2 Pro itself may be faulty, but it’s strange because it DOES work in certain configurations.
Has anyone else had an AMS 2 Pro work through a filament buffer but fail through the AMS Hub on A1?
Would really appreciate any ideas or experiences before I go further with warranty support.
Thanks!
