Points noted @great white . The difference between a skirt and a brim is the skirt doesn't touch the part. If you reduce the distance of the skirt so that it touches the part, now you have a brim. Semantics...

yes a brim...A skirt doesn't help one iota for a lifting print because it is not attached to the print. A brim is most likely what you are referring to.
Maybe I got too excited towards the end of my build and skipped that part by racing aheadI just purchased the newest Prusa Mk3+ and getting near the end of the build. When reading through their 3D printing basics book, they explained in detail the purpose of each pre-print detail. Skirt, brim, rafts, etc.
According to Prusa, the skirt provides some sort air dam barrier between airflow across the heated bed and the portion of your print that is adhering to the bed. Basically you are creating an area of turbulent airflow inside the skirt area, keeping the temperature immediately around your print more stable.
I don't know why either. I basically did what you wrote, and the results were not as expected.I'm not sure why you're having so much trouble with petg. I just dial in a print temp somewhere in the middle of the filament range (printed on the spool) and same with the heated bed (don't recall temp offhand, I think around 80-90c)).
Hit print and it comes out fine. I hardly touch the settings at all in cura.
I have had a lot of spalling lately on my glass build plates though. PETG seems to grip build plate pretty tenaciously. So I switched to stainless steel build plate and no more spalling problems.
acetone??I don't know why either. I basically did what you wrote, and the results were not as expected.
There's a couple of mitigating factors, I was printing thin walls vertically because my bigger piece had vertical thin walls, and maybe the filament was damp. The PETG has been in a tight bag with silica gel for a while now. I'll try again in a bit.
Unfortunately when I printed a thin structure test cube in vase mode, the 40 x 40mm base sort of fused to the sheet. Can't get rid of all of it. Most of it is gone, but it's maybe 0.25mm higher in the dead middle of the satin sheet. Can I use a metal scraper to get it off? Tried a pla scraper but it didn't take off much.
Sorry, I'm not familiar with "satin sheet" build plates so can't offer any help there....I don't know why either. I basically did what you wrote, and the results were not as expected.
