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.

If this was during an auto level, it's my humble opinion that this is a manufacturer's defect in the machine that caused the damage. There should be proper coding to ensure that any increase in sensor pressure by (delta p) halt that machine and that there should be a pressure offset in the sensor such that a loss of signal or anomalous zero reading or lack of reading is done prior to levelling to ensure that a sensor failure has not occurred. My XL freaks out if a fan isn't spinning at the right speed, so they clearly know that a nominal operational check before the print starts is proper engineering design.

Of course you won't get anywhere. Unfortunately, a lot of 3D print failures really are user error so I suspect that's their default response and it takes them a good deal of proof to push them of that mark.

I 100% agree, however I went Prusa for their replacement parts and long term support of said parts. Rather than their quality which outside of the bed levels on uneven surfaces has been good.

Oh, I didn’t mean to come off as dissing Prusa in general. I ponied up for an XL and it’s night-and-day better than any previous printer I’ve owned.
