I've had a running Prusa MK3S with a Pi 3B permanently connected, and Octopi working fine with it for a year (also on my second Mk3S). Over the last week the printing stopped "sometimes" - I cannot reproduce it. As of last Monday I could not print at all anymore. To clarify: I see the printer in Octoprint on my Mac, it does connect, but I do NOT see the actual temperatures of the bed and the nozzle. And the "print" and "load" buttons are greyed out.
My apologies if I'm posting in the wrong forum, I've searched for two days to get solutions but can't seem to ask Google the right questions.
I verified all the software settings in the Pi, on the Prusa, and in Octoprint (this is the link describing all steps)
I checked the wiring between the Pi and the Einsy board, even replaced them.
I installed a clean Octoprint version on another Pi, and connected it with the USB cable to the Einsy board. It now runs these versions:
OctoPrint version : 1.8.6
OctoPi version : 1.0.0
This solution works, but it isn't using the RPi connection. So I wired this new Pi to the Einsy. Voila, it works.
Next step: the SD card with the working Octoprint in the original Pi. Also works.
So I'm up and running again (assuming the problem isn't intermittent), and I don't see any differences besides the use of a different SD card.
I may not see the problem for looking at it too long. And I would like to understand what was wrong, please share thoughts on this problem.
Yes, same result
You can download this in OctoPrint's System Information dialog ... no bundle, no support!)
Let me know if this does not work:
