Mine is also having this problem. I’m scared to turn it off now that i got rid of it. But what i did. 1) turned off the machine, 2) opened lid 3) Put the laser head in the center under the camera 4) turn on the machine 5) let it sit for like 15-20 mins 6) close the lid and let it go through its cycle
if your lucky it will slowly go through calibration and pass the centering/focus problem.
Let me know if it works for your machine or its just something that works on mine.
That’s been reported before when they’re loading something to your machine - it can hang up if it’s also trying to center. Leaving the lid up lets the update finish before it tries to center.
