I've had a MK4S for over a week now, and 100% of the prints I've tried to make on the textured sheets have partially or totally failed. PLA prints beautifully on the smooth sheet, but PLA, PETG and ABS, I think I could print on the surface of a 10 inch tank of oil with more success than the textured sheet. Plastic doesn't stick to it. I've wiped it with isopopyl, I've washed it with dawn...it's a bad print surface and I want my money back.

Back when I had a Prusa I never had any success with the textured sheet and PLA, however it worked perfectly with PETG.

    PETG, PLA, ABS, I haven't gotten anything to stick to it. It's "powder coated" but it doesn't say what powder. Is it teflon?

    Stupid question, you sure you are using the right bed temperature? The feature of a PEI textured sheet is that it self released the part when the bed cools down,.

    That is not a stupid question. That is a valid question. I'm using Prusa's provided templates in PrusaSlicer. This includes Prusament PETG with the Prusament PETG template. This is a stupid question: As many parts as Prusa makes printing Prusament PETG on Prusa printers with Prusa build sheets, wouldn't that material template be well tested?
