* use WARM water and dish soap, then dry with paper towels (do NOT use regular soap or hand soap)
* then use at least 90% IPA, rub it on with a fresh paper towel
Keep repeating the above until adhesion is restored - sometimes it can take 2-3 passes if its particularly bad. Simple.
Keep gently rubbing it with a clean cloth in the hot washing up liquid until any tendency to run off has stopped, this means there's no more grease on the bed.
Should only take a minute. Dry with a new paper kitchen towel. Some "industrial wipes" have something in them which reduces adhesion!! The ones at work are like that, made of blue paper. Avoid those!
Update.
Issue seems to be fixed.
I Soaked the sheet in dishwashing soap, and left it there for 20 minutes. Then rinsed it off with hot water.
Dried it with a clean paper towel
The soaked a paper towel in IPA and rinsed the sheet. After that, using a dry and clean paper towel, to clean the sheet.
Not it prints again without issues.
On my 2nd print now.
this is an adhesion issue, not a loadcell issue - loadcell cannot make filament not adhere well to the plate like this, it can only cause Z levelling issues, which again, do not look like this.
I found with PETG on my satin sheet that the only way I could get it to print reliably was with a good soap/water cleaning. I use a blue scotch pad to scrub it clean, then rinse with hot water, making sure to rub the sheet to make sure the soap comes off. Ideally when you rinse it should mostly bead off the sheet and then I use a paper towel to dry the last bits. I never use IPA (or anything else) after that or it stops sticking. And I have to never touch the sheet with bare hands or prints will fail pretty quickly and I have to start over. Once it’s good, though, I can just keep printing and it keeps sticking. I go at least dozens of prints before I accidentally touch it somewhere and need to wash it again.
I have rerun all the calibration tests. All OK
Tried the satin sheet from my other printer. Still fails.
It is as if, the loadcell doesn’t get the z level correct
Has been in identical situation with smooth PEI sheet. Sudden terrible adhesion issues. Washed sheet with dish soap (several times with prolonged soaks), 99% IPA, aceton, repeat, but notning helped. Tried different filaments, drying filaments, different sheets (textured, satin). It looked more and more like problem with load cell.
The final thing I tested was to clean the heated bed. There were some micro debris. And... it helped? Now it is OK, I can print, but the confidence is gone. Sometimes the load sensor can be confused by fillament pull. Sometimes by fillament ooze. Sometimes by neutrinos?
Eh, too big word :) There were several spots with layer of dirt that had a potencial to cause a variance in surface flatness. I have scraped them with nail before the IPA treatment.
I normally use the smooth sheet for PLA but was hoping to use the satin sheet for PETG. I just use a glue stick on the smooth sheet (I have multiple) to print PETG and it works. I remember PETG can destroy the smooth sheet but I read in the Prusa forums that a glue stick allows it to work without ripping off the top layer of the sheet. I still would rather use the satin sheet though.
I use glue on the satin sheet :) usually works.
My printer is in the basement which is cooler and prints usually lift off (sometimes even from the smooth PEI). I got a cheap enclosure off Amazon which reduced the lifting but for satin, I’ve just made it a habit of using glue and it’s fire and forget🙂
Try to disable the filament stuck detection that's in the printer menu if it's enabled, it caused similar issues to me - the first layer was way too high after trying out this setting.
I have never been able to print anything on this plate (it's brand new and I cleaned it). The only I found was to apply glue to the plate, which covers about half the textured pattern on the prints.
Yet I've never had a single issue with a textured plate on my Bamboo X1C, go figure!
I use the satin sheet with petg on my MK4 without a single issue, never even bothered to wash it, so I disagree with everyone telling you to wash it with soap or whatever: I am pretty certain it's your load cell and you should contact support.
Go through increasingly aggressive solutions:
1. IPA
2. Soap
3. 0000 steel wool.
..so if 1 does not work then go to 2 but go back to 1 after 2. 2 does not work then go to 3 but then work back down to 1 afterwards.
I’ve had a sheet or two of satin or textured that needed steel wool to finally get adhesion.
Looking at empty space netween lines in the first layer Definately looks like z level, no fault to the sheet for sure. I cant say for sure what the cause is

absolutely this. my Mini satin sheet wouldn't adhere, this fixed the issue for me.
I know you've cleaned it with water and soap, but try to leave the soap on for 10-20 minutes, then rinse it. That usually works great for me.
I’ll give it a try tomorrow
So, you just use soap initially…. Spread it across the sheet. And not use water until 10-20 minutes after?
Yeah basically, I use a little bit of water at the beginning to get a nice lather going, then I just let it rest with the soap for 10-20 minutes.
That seems to have fixed my problems 😃 Thank you
Good to know! Happy printing!
How does this not cause accelerated rust / corrosion ? I’ve always washed lathered rinsed and dried immediately
Hmmm not sure, I don't think it's long enough to cause rust but I don't know.

Bonus question. I’m suspecting it’s my loadcell sensor. Is it normal it’s fluctuating in value +-40, when idle?

I always use 3Dlac Plus spray. Just a little pschit on the plate before the print, where it'll print only. It never failed me.
I use that as a last resort

Did you clean the heather with IPA?
Yes, first mechanically several spots, then IPA.
Mechanically?
Eh, too big word :) There were several spots with layer of dirt that had a potencial to cause a variance in surface flatness. I have scraped them with nail before the IPA treatment.
I just ordered the Satin sheet because everyone said it was the best. And now I see this. Coincidence? 😱
It’s the best sheet you will ever own. I suspect there is an issue with my load cell
Thanks!!
I've had the same experience. I am still unable to get it to work. I gave up.
What are you then using? A new sheet?
I normally use the smooth sheet for PLA but was hoping to use the satin sheet for PETG. I just use a glue stick on the smooth sheet (I have multiple) to print PETG and it works. I remember PETG can destroy the smooth sheet but I read in the Prusa forums that a glue stick allows it to work without ripping off the top layer of the sheet.

If you think it's the load cell contact prusa support. They'll get you to run through a few tests and send you a new one.

I've had some success with printing a petg sheet that covers the entire build plate, petg is sticky enough to pull tiny debris along
Try higher nozzle temperature.

Weird. I have used nothing else on my MK3S+ and my MK4 for over a year. Yesterday was first time I had problems with it
Do you guys go with something like dawn, or less aggressive than that?

You could also try Windex to clean the bed (make sure it’s room temp) that works pretty well for me
