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.

Grease is bad for those PEI sheets. I wipe it off with alcohol before every print. They need to be hot, too. Around the glass transition temperature of your material. I exclusively print PETG. 70°C will fail, while 85°C will stick great.

    Glue stick on glass. Got it. I'll go to Lowe's first thing in the morning to get some cut to size.
