What is the problem? Octoprint will not connect to printer. My deltamaker printer had been working great, then during a print it lost some steps and after a reboot would not reconnect to the printer.
What did you already try to solve it? rebooted into safemood, replaced Pi, updated Firmware, rolled back firmware, replaced SD card, replaced USB cable from Pi to control board, replaced control board, cussed at it tried separate power supply for the PI, cussed at it some more.
