Printing over USB #
When printing over USB the LEDs may not automatically change to green after a print completes. This may be fixed in a later firmware release but for now, the workaround is simple.
To accomplish this all that is required is to add the below GCode line to your slicer ending GCode after all the other existing code that is there.

Please note that this will only work with files sliced after the update is made to your slicer scripts.
You can also place this in the “After print job completes” section of OctoPrint to achieve the same effect with the lighting instead of placing it in your slicer ending gcode scripts.
