What is the problem?
I've had my Ender 3 Pro for a few months and have been printing from OctoPi from day one. I recently printed my longest print which two 24 hours. I rested the printer for about a half a day and then started printing another item estimated to take 14 hours. about 4 hours in, it just stopped. I send it to print again and again at the same point in the print process (the two items look to be around the same height) it stops printing again.
At this point I think its the GCODE so instead of printing the same piece, I print another item estimated to take 5 hours. about 2 hours in, it stops too. This time I was by the printer and saw that the Ender 3 Pro screen flashed, showed the logo, then the regular screen. It looked like it rebooted.
What did you already try to solve it?
I searched for possible issues and saw that it could be the power supply unit (PSU) to the Raspberry Pi. I changed it and saw that i no longer had that power issue warning in OctoPi. Thinking I solved the issue, I went back to print the first one that failed. Right around the same point it fails once again.
Additional information about your setup (OctoPrint version, OctoPi version, printer, firmware, what kind of hardware precisely, ...)
Ender 3 Pro
Not sure about firmware - i haven't touched it.
