I had issues with mine, nothing was sticking to it causing 100% failures. I forgot where I read it but I ended up scrubbing it good with one of those slightly abrasive green pads in warm dawn dish soap, drying it with a clean microfiber cloth and putting it on the bed with the heat set to 60c for a few minutes. It now works extremely well with pla or petg, I just wipe it down with a bit of 90% alcohol between prints. Never had any issues with the smooth and satin sheets.

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.
I chipped so many glass beds back in the day with PLA and Elmer's glue stick. I'd often put them in the freezer in hopes that they'd just release on their own. Alas, they chip there, too.
Tbh I've used hairspray and glass with no issue as well. It cheap after and easy to clean. ¯\_(ツ)_/¯

Yes. Mine has worked amazingly well.
My textured one is perfect for petg, never have sticking issues. With tpu, I need some glue stick as a release agent because it sticks too well.
I only print pla on the smooth sheet, works well.
And have had mixed luck with both petg and pla on the satin sheet.
Have had a very similar experience with the sheets on my mini, and now on the core1
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?
Its PEI, powder coated. Everything should stick to it with out any adhesives. Soap?
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?
I clean mine with isopropyl alcohol every other print or so.
So, to clarify, you've EVER gotten yours to work? EVERY SINGLE part I've printed on that sheet has partially or totally failed, and I've cleaned it repeatedly.
I've been printing on glass and glue stick since the Obama administration, and that actually works. You know what? Fuck magnetic sheets, I'm going back to glass and binder clips, because they actually goddamn motherfucking work. I'm sick of people unsolving problems.
Yeah its been better than the smooth one, but I long ago got into the habit of using hairspray on every print.
I've been using hairspray for years too. I don't get how people prefer chunky glue sticks or $80 "specialized" bed adhesion fluid over a nice uniform spray from an $8 bottle of Suave unscented.
I find the smooth one works adequately for PLA. I don't have a satin one, and I think I'd have better luck printing on an inch deep tank of cod liver oil than the textured sheet.
I'll go back to printing on glass and glue stick before I start fucking around with hair spray.
I've tried all 3 and found hairspray the absolute winner of bed adhesion and it's not even close.
I've printed PETG on glue stick on glass since Obama was president and until this week I would have told you PETG doesn't peel the corners up like ABS does.
The only times I've had that happen was when the sheet wasn't clean enough (which yours definitely is if you've scrubbed it with dishsoap), bed temps too low or first layer being too close to the bed (though the textured sheet wants more squish)
The satin sheet is imo their best sheet, buildtak does some great surfaces in that size (pei sheet is great for even abs, their new surfaces are great too). I moved to using fr4/garolite sheets (I use this on my former mk3s, have a larger one for my voron too), not really found I needed adhesive for petg or pla on that.
Yeah the texture sheet works, but I would never use it with PLA. I only use mine for TPU and sometimes polycarbonate. Anything else is either smooth or satin sheet.
I use a textured sheet for all of my Prusament PLA prints on my Core One and XL, and it's never given me a hint of trouble. I'm using the Prusa-provided profiles with zero tweaks.
I just hit it with a bunch of 99% IPA while it's cold and scrub it with paper towels before every single print. I don't heat it up until all of the IPA has dissolved, since apparently PEI is incompatible with hot IPA. I've never washed my sheets with soap, I've never applied any sort of bonding agents to them, and I've never sanded them.
Maybe you just have a bad print sheet?
You mentioned using Dawn. Did you use the hottest water you can get from your tap, and maybe wash several times? I remember having lots of trouble with my textured sheet initially, but after a few good scrubs with really hot water and dawn, it finally started working just fine. Like there was some residue from manufacturing left on it that took some work to get off.
Per Prusa's Knowledge Base I washed it with "warm water (not hot!) and a few drops of liquid dish soap (not hand soap)."
I'll go get out my canning pot, boil up 5 gallons of water, and scrub it with a brillo pad and some brakleen. Can't fuck it up any worse than Josef himself did.
PETG on textured sheet from prusa here. Works like a charm, and I don't even use a gluestick.
Is your sheet perfectly clean? Scrub it with a dish washing brush, dish soap and warm (not hot), and dry it with a lint free towel. Even fingerprints (visible or invisible) is enough to ruin adhesion.
Mine works beautifully for petg but pla not so good. Trick is absolutely clean. Fingerprints are enough to ruin it. Keep using dish soap and be sure to rinse well with warm water. Forget about isopropyl! Use a fine dry microfibre cloth before printing. You can use a spray of 1L water mixed with a few drops of dish soap on the cloth but if the plate is already clean a dry cloth can be enough most of the time.
Finally make sure your first layer height is adjusted correctly. The plastic needs to he squished slightly more into the textured surface. If in doubt go closer until you are defiantly too close (like almost scraping) and then back up up again. Then you are sure.
I’ll use the textured with Prusament PLA on my MK4S with great success but have to set bed temp to 70C. Prints with sharp corners will still lift if they are large.
Textured with Prusament PETG and Sainsmart 95A works without changing profile settings.
Satin for most of my PLA though. My smooth sheets have accrued PLA residue and are more trouble than they’re worth.
I'm the kind of guy that, when I find something that works, I'll stick to it for a decade. Hence why my Folger 2020 i3 with its mirrored glass print beds were in service until 2026. PLA prints well on the smooth sheet, so that's what I'll do until America elects a female president in 2036. So PEI is going to be my fascist era print bed. I printed on glass when we were a republic. Polymer print sheets are for dictatorships I guess I've decided.
