Describe your issue:

I had a print running for about 9 out of 10 hours, when it suddenly stopped while reporting the print being successful. I have not found an error or warning in the klippy.log, just

Finished SD card print
Exiting SD card print (position 46833012)

I have not found any errors in the moonraker.log either. The print still need about an hour or about 10-20 layers. Any advice on how to find the culprit here? The SD Card is barely half a year old, and the gcode I downloaded from the SBC seems fine. According to the klipper log analyzer, CANBUS doesn’t seem to have caused any problems. I started another print afterwards, it started without issues, but hasn’t finished yet.
Happy to provide any additional information, the SBC has not been rebooted thus far.

Welcome Mitrimo,
It could be your gcode. Please post it.

I’ll upload it later tonight, it’s too big to upload and I can’t properly edit it on the phone so the zip is <8MB.

Here’s the zipped gcode of the print in question. Only thing I’ve changed was to remove the thumbnail generated by Orca. If I import the gcode into OrcaSlicer, it shows the full print - by my estimation it stopped the print at layer ~77-80. Nothing seems out of the ordinary to me for now…

My idea was “non-ascii characters”, but your file looks good. Sorry, no other idea.
