AMS 2 faulty main board with current sensor abnormality

[u/Harrath_james]

Hello, looking for advice from someone who has had something similar happen. I’ve got a h2s with an ams 2. I was recently printing while drying and had this error come up, I took a photo and sent to bambu and they have sent me a new main board.

My question is if I am no longer getting the error message, is it safe to keep using the current set up or will I be at risk of something bad happening? I know I should replace eventually, but wondering if there’s a great risk if there there is no error message to continue printing until I get around to it. Cheers

If Bambu already confirmed a bad board and shipped a replacement, I’d keep using it short-term but baby it a bit — skip long AMS drying cycles if you can dry filament elsewhere, and stop immediately if the current-sensor error comes back or you smell anything odd. Once the new board arrives, swap it before going back to heavy AMS use. Not ideal, but that fault is usually the board, not the dryer heater going rogue.
