Awful top layer on large flat prints
For some reason, large, flat objects get bad top surface defects on certain areas of the print, while other areas are "ok". I put ok in quotes because the top layers are never great, just accptable. But I print mostly functional parts so looks aren't terribly important, but this just sucks. I tend to leave mostly default settings, as historically they have worked fine for most of the things I print. And on objects that are not flat and large, everything is pretty good. However large, flat top layers, well, suck.
This was done using prusament PETG using the standard .020 balanced profile and the prusament PETG filament profile.
Two prints, both looking crappy in the same area, - left rear quarter of the plate. Going to calibrate again, and try again...
You shouldn't be having any exposure to drafts so make sure your print sheet is really clean and consider using a brim or 'Mickey Mouse ears' - helper discs on the corners.
Cheerio,
RE: Awful top layer on large flat prints
Thanks, but I'm not getting any corner or lifting otherwise - they remain solidly adhered to the Glacier plate I am using, so how is the plate condition relevant? The objects i showed are about 1/2" (14mm) thick (tall)
Also, I spent years printing on my Mk3s and Mk4si which are open bed slingers, and never had such issues?
Show us the underside of a failed print.

Will do, a bit later.
