Prusa i3MK3 stops printing over USB/serial
After 4 month of successfull work, my (new) Prusa i3MK3 stops printing over USB/serial.
First fails stopped randomly @ 25% or 50 % or 66%,
now the printer stops after heating/bed levelling.
Using Octoprint@Raspberry Pi for years, suddenly stops.
Changed power supply, USB Cable ... nothing.
Tried Octoprint @QNap NAS ... nothing.
Tried printing with Slic3r PE & Windows ... nothing.
No physically (print) crashes @ all.
BUT: PRINTING FROM SDCARD WORKS FINE 🙁
What could be the reason ???
Example:
Loved my MK3 so far ... best printer ever ...
Re: Prusa i3MK3 stops printing over USB/serial
Check to see if your RPi Port became enabled somehow. I don't think you should be able to heat/level if it did, but I can't remember the exact symptoms.
See if you can make it do anything with Pronterface. If you can home the printer, then the USB port is fine.

2 Days later
Pronterface dont work ... after 2 or 3 (manual) movements printer stands still.
And now: printing from SDCard also stops after a random period of time.
ONLY THING THAT WORKS IS FLASHING FIRMWARE 🙁

Hi Christian,
that sucks. I would recommend to got to Prusa's support chat and debug with them.
IMHO that is not normal. Maybe your PSU is failing - or your EINSY? Or some other component? I would expect that Prusa support stuff would be able to figure it out.

i had something similar but with layer shifting for no reason and while I watched. This was in the first 2 weeks of printing with it and the full factory reset fixed it...
This is sort of like the base response of a malfunction in a computer being a reset. (in the early days of PCs in the 70s and early 80s they had hardware reset buttons and on one computer I had it would also clear the NVR if another button was pushed at the same time, the basic access items that enabled you to load the OS then had to be reinstalled via a punched paper tape... we used to joke about the problems that required this drastic step being caused by random cosmic rays... one person in the computer center at my college we were certain was cursed 😯 as the PDP10 (programed with punch cards) seemed to go haywire when he was around. 😕
