I have a problem with my Prusa MK2S and I hope that someone here knows how to deal with it.
I've had a few prints just stop in the middle. When I went to the printer, I believe the screen showed "card inserted" or something like that. My suspicion is that the SD card got momentarily disconnected, which caused the printer to pause. (By the way, resuming afterwards didn't help. For some reason the extruder wouldn't heat up until I adjusted the temperature manually, and then the printer made wrong moves and crashed into the existing print. But that's a question for another time.)
Any idea whether my diagnosis is true, and if so, what I can do about it?
Thanks for your help,
