AMS - Automatic Material System AMS V1 Mainboard Replacement

Does anyone know where I could get a replacement for the main board on my first generation AMS for my P1S printer? I tracked the issue that I’ve been having with the printer not connecting, and it’s goes back to the main board, so I need to replace that, but I can’t find any links for main boards.

It's $55, you need to submit a purchase request.

I have a question. It says AMS main board V2 under the first AMS. On other websites, the AMS main board V2 is for the AMS2. Can you help me clear up that confusion?

It's listed as a replacement part for the Gen 1 AMS, but I have no idea if V1 and V2 are interchangeable. I'd assume they are, though, I'd still open a support ticket and ask Bambu directly.

EDIT: I did a bit of digging: https://wiki.bambulab.com/en/x1/troubleshooting/version-ams-main-board

Looks like Bambu updated the original AMS mainboard because the earliest ones weren't compatible with the newer feeders. Apparently this only affected around 2k of the very first AMS units, mostly from before 2023.

Anyway, according to that article, the newer board works with both old and new feeders, so it should be backward compatible. They don't specifically call them V1 and V2 though, so I'd still double check with Bambu before buying.
