I have not received my unit yet, so maybe I am just confused and don’t understand the calibration issue.
What I read from the forum is that the solution to many calibration issues (and the head trying to move past where it physical can) is to turn off the unit and then move the head.
my concern with moving the head: when you move a system with a motor attached you will create current. Does the glow forge have protection in the system to handle this current that is being produced by a motor when the system is off? Does Glowforge recommend that you only move the head when it is still plugged in (so that the ground is still functional).
it would be nice to include this type of information in the manual.
