 One, the firmware on the motion controller may not be in sync with the firmware on the other device(s). Our fix for this is to flash a known version to the motion controller and a compatible version to the print heads. However, this is not usually the root cause unless you are working with some older equipment which has not been properly updated during 2016 or later.

 If we still haven't restored the heartbeat, there is some issue with the motion controller itself, so we should flash the current firmware onto it again:
