Word of warning to those with Prusa MK4 and Satin beds. There is a chance that the auto bed leveler will mess up and destroy your print surface. (lemmy.world)

I've tried to report the issue to Prusa support but they keeps trying to diagnose it as user error. But at this point I'm at a loss and presume that it's either a firmware issue or a sensor issue on my unit.

Either way im very disappointed.

And before you ask, this is the opposite side

EDIT: I will note that this print sheet is ruined for my use case, since those patterns will be shown on the underside of my prints. But the print surface still works and can be used without issue... if you ignore the gouges that are being detailed into every print.

Are you sure the surface is damaged, and not just some material stuck on the sheet? Looks to me just a very thin layer of material on the sheet.

Oh I wish it was. I was even printing in clear. But sadly no it's permanent.

I had a similar thing happen to my smooth PEI sheet. Forgot to change sheet profile before printing and printer made some noises during printing. At first thought that the sheet is damaged, but after several days noticed that the sheet is actually fine. The noise was the extruder skipping because there wasn't enough room for the material to go anywhere, and the lines on the sheet were just a very thin transparent layer of the material. Difficult to say from the images, but the lines seem to have the texturing intact? That implies the sheet is fine. The thin lines are difficult to remove without damaging the surface, especially because you have textured sheet, so you can't use any solvent like acetone.
