Crashes, communication errors, and failed prints.
SO, I have a RPi2 running octoprint. Connected to an Arduino Mega / Ramps 1.4 based printer running Repetire Firmware. Over the last week or two, the printer would freeze and kill the print at random points during the print. I noticed that the logs for the octoprint said there was a connection issue, that it can happen during long commands, and that it was unable to reconnect. For me to reconnect I have to turn off BOTH the octopi and the printer. An other thing, is that the display on the printer turns bright white. Also, when the printer is off, and connected to the octopi, the arduino is getting power from it so its running. When I turn the printer on (its relay controlled by the octopi), the display get much brighter. Could this be a voltage issue? As if its getting voltage from both sources? I can print successfully using my laptop (Windows 10) and Repetire Host. Im not sure where to start looking to troubleshoot this. As it seems random, and was working fine a few weeks ago.
