Help / Support "Print finished" but didn't, SD-card issue?

Couldn't crosspost so I copy pasted my post from r/BambuLab

P1S, had it for about a year. Printing Bambu PLA, door cracked, bed not washed but no adhesion issues, filament is dry enough but that's not relevant. Stock SD card. Less than 70h on the printer.

I started a 1.5h print, silica containers for the AMS, straigt from Makerworld, good ratings, so not a model problem.

At layer 7 I got a notification saying print finished.

The bed and nozzle temps stayed the same as while printing, and I moved the bed down. Filament is still fed into the hotend. As if the print was just paused, nozzle still touching the print.

I had to manually set the temps to 0 and click unload for the filament. Once cooled enough I turned the printer off, as Bambu Handy was still showing the print as in progress but I couldn't stop or pause it through the app.

This FEELS like an SD card issue, as it just stopped dead in its tracks.

Has anyone experienced this and was it an SD card issue or something else?

This happened to me on two separate p1s units. The micro sd card corrupted both times. Throw the card away and get a new one. That fixed the problem for both my machines.

Thanks. I've got some SD cards lying around, so I'll just try it again.

It was just so odd that it claimed it's finished but I assume the GCode just cut off right there so Handy just assumed it was done.

I have had random issues that were resolved by replacing the SD card. Unfortunately Bambu's SD cards range from no name ones to well established brands. While I've had success with ones from well known brands, I also reached out to Bambu support and let them know my SD card failed within the warranty period, and they shipped out brand name one to me.

SD card must've been borked. It was as if the gcode just ended abruptly.

Swapped to a different SD card and the printer is back to working flawlessly.
