Been printing successfully for months on my A1. Printing a small part (20mins) and the A1 paused mid-print. Moved head to purging section and cooled down while fan remained on, but it sat there for minutes. Pressed play, nozzle heated back up, moved over part and then sat there doing nothing. Ended up canceling the print. No added pauses. Only change I had was adaptive layer height in the area where it paused. I’ve printed multiple iterations of this part while I refine it as well, so not the first time. Anyone experience this before?
Usually when it does that, it’s a filament feed issue…but you didn’t mention that.
I would try a different SD Card…even if you sent the file from BS to the A1…it downloads to the SD Card.

Interestingly, I sent it to print again and walked away for a bit. Came back and entire model was a blob. Luckily it was on the build plate and not the end. Going to clean the plate and try again.
This has happened to me twice in a row on 2 separate A1 Mini printers and has also paused both printers at the same time so this is likely a bambu cloud issue. So this needs to be looked into. This isn’t something that should be happening. And it’s not a single case because it happened on 2 separate units within the same timespan and it has happened twice in a row too. Though the second time was on a single unit as the other print had already concluded. So whatever is causing it it makes most sense for it to be related to the cloud or wifi device or something similar.
There is another solution to this. If your printers are on the same circuit as a fridge with a compressor that’s kicking on it can stop the prints. I never had any issues until today when I installed 2 plugs that had previously been in place but not yet had replacements installed. And the compressor on the fridge only caused this issue for my monitor. I just moved the fridge and felt the compressor bump into something so the printers are probably pausing when the compressor kicks on and off. So yeah anyone else having this issue should probably check what else in their local power is causing micro outages.
If the print job started, it’s unlikely the cloud as the file downloads and prints from the SD card. Try swapping out your SD card. This fixed my issues. Not the first one here to a report bad SD card, so BL should be looking at providing better quality ones.
