I had a problem with my unit sensing material height on .02" material that I’ve cut hundreds of times in the past. Had the error in October but everything has been fine for a month until today. It gives the “Material Height” error and won’t let me run the print.
This only ever happens on a job where I’m printing duplicates of the same file. So I tried placing just one in the center of the material, set manual focus to .02", and hit print- it gave a time estimate and no error. Cancelled that. Then I added the rest of the duplicates, and hit print again, and it’s working now.
Hope this helps if anyone else is getting this error for silly things now and then. I tried everything else I could find on the forums before this with no luck.
