This is for informational purposes only. I don’t need help. But an explanation could certainly hold value!
Turned on the machine, it “headbanged” from top-left to mid-left. I’m sure you’re familiar with this event as many, including me, have demonstrated it. But I’ll explain further… As it traveled from top-left to center-left, it was as if it was scraping itself against the left wall. Okay… After that it just sat there. Did nothing at all. For several minutes. Okay, fine. Powered off. Manually homed to under the camera. Wouldn’t be the first time it was necessary. Turn it back on. It just sat there. Never calibrated. Never moved. Just sat there. Again, left it alone for several minutes. Turned it off again. Moved the head ever so slightly to, like, perfectly under the camera. Turned it on. Went through its normal calibration within just several seconds (less than 1 minute) like it usually does. Engraving just fine.
Figured Support should be aware so it can never happen to anybody ever again.
