Printer stops mid print
There are known defects in 3.8.x that cause odd positional problems while printing. They probably can also affect printer state. These defects are often avoided by simply disabling the filament sensor.
I'll try that.. Not even sure the filament sensor is useful when using octoprint, so will disable it and see if I can get through this print.. Just in case, not starting it until tomorrow - don't want it burning a hole in the print when not watching it. 🙂
