This is the wax and grease remover. Better in a post than a link you have to click on. I have some solvent based wax and grease remover too but it doesn't work as well as the water based. Just my observations.

The very light sanding made a big difference and alcohol wiping worked most of the time and soap and water worked most of the time but the best, most reliable wipe I've found is water based wax and grease remover made for automotive painting. I painted a car a year ago and the irritation we have when we lose a print after a few hours is nothing to what you feel after spending months prepping a car for paint and then have a problem when you are laying down the last coat. You don't take chances on stuff that "should work". This water based wax and grease remover takes off everything and prints stick.

I've tried everything when the bed arrived without any success, only the sanding give me a little grip with pla. I will try to scrubs with dish soap again , but it's very frustating to throw a lot of half printed object in the bin.

I ordered a TheKKIINNGG knock-off which has been exactly what I was expecting. I don't like going the clone route, but I was spending too much time trying to work around this "quality of life" feature.
Prusa's not acknowledging this is a problem, and if you contact support, they'll tell you it's a consumable, even if it fails on the 1st print out of the packaging. I'm surprised they can get away with that in the EU, but I'm in the US so have no recourse. Very disappointing after waiting more than 14 months for the thing.

I'm in europe but it's the same thing , if you have time to waste you can try to obtain satisfaction but it is difficult. I talked with the support but they talk always about z level , soap and all the other things , but I really think there are some lot of items that don't work fine and they don't want to admit it ( and refound the people ). Certainly this experience will count in my opinion of the brand Prusa.

I'm looking at the bed you are talking about and seems difficult to find in europe. I will look for other alternatives.

I had the same experience with the textured powder-coated sheets. There seems to be a lot of variability. Some people are getting great results. I never got good adhesion, even with PETG. I've given up on PLA due to a similar experience with wasted attempts. I'm giving the blasted thing away.

Hi,
After few prints after the sanding , the PLA start to detach again . I'm so annoyed about this situation. Has anyone tried to use hairspray ?
Note that sanding is a seldom to never operation.
Scrubbing with dish detergent every few days - as needed. When IPA wipe is not working.
Scrubbing with IPA and fresh paper towel after every print to every few prints.

@pablosimone

Thank you for the idea of lightly sanding the textured sheet. Night and day difference. I had a PLA part that always curled, even with vigorous scrubbing with Dawn and alcohol. Just a little light wet sanding and it sticks like it's glued. No lifting at all! All I had was 1500 wet and dry but even with using that, the sanding marks are not visible to the naked eye.

What a difference that made.

thank you, thank you.
