Ah ok

I cleaned it with the wipes Prusa included. These are apparently alcohol-soaked wipes. I've now cleaned the bed with soap and water. With that in mind, cheers 😉

Every once in a while clean with dish soap and water and in between prints I use 99% isopropyl alcohol. Don’t have issues with adhesion if I keep the plates clean in this way

Nothing else works as well.

Rule 1: never touch the printing surface of any print sheet. 

Rule 2: alcohol dilutes oils and produces a very nice invisible sheen on print sheets.  Proof of this sheen is when nothing sticks to the sheet.

Rule 3: detergents are surfactants that lift the oil away from the sheet so it can be rinsed away with flowing water.  

Rule 4: a clean sheet beads water that then sheets off leaving a clean dry surface.  

Alcohol can be used to remove certain plastic residue, but detergent and hot water are often required after the alcohol to actually clean the sheet.   I have on occasion used an ounce of alcohol to clean a sheet ... that's OUNCE, or 1/16th a pint bottle... And many paper towels to sop up the liquid before it evaporates leaving whatever oils it had moved around. Pour the alcohol, briefly scrub, then dry with a fresh towel. But even using copious amounts of alcohol you will still end up with an oil film.

Cheerio,

My edges are curling when the printer repeatedly moves back and forth to print the frame of this support structure. I'm using the default settings of the Prusa Slicer with original Prusa filament PLA. Perhaps someone can tell me something about this. As you can see in the picture, the other edges are perfectly fine. I've already increased the print bed temperature to 70 degrees Celsius. The same result is achieved with the default settings of 60 degrees Celsius.
