Printing stops after 30 - 50 minutes
Raspberry Zero W
Prusa Link 0.5.2
MK3s 3.10.0
I have started three different prints, two via Prusa Link and one directly from the SD card, monitored by Prusa Link. After 30 - 50 minutes, the printing is repeatedly aborted with the following messages.
Aug 18, 2021 7:16:00 PM Printer state chaged to READY
Aug 18, 2021 7:16:00 PM Printer state chaged to ERROR
Aug 18, 2021 7:16:00 PM Printer state chaged to STOPPED

I suspect the serial connection will be re-established and the printer will reset or restart. I checked the uptime of the Raspberry - it did not restart.
same gcode file each time?
Are you printing the same gcode but it is aborting at different durations?
was the hotend still at the printed object?
I had a print fail that was caused by the file I uploaded not uploading completely. I ssh'ed in and checked the file size against the duplicate gcode I saved at the same time I sent it to PrusaLink/Connect
^^ That. I've had transfers interrupted a few times when I slice and send a complex part and then wander off to the kitchen and use the microwave...
That's a good catch. How about adding a checksum check to the upload? Digest or TLS (I assume TLS is harder in our use-case).
We are working for some simple check file mechanism now. Thanks for report.
