PLA sticks too well
I usually print with PETG for mechanical parts but went with PLA for this model body shell. I used the smooth heatbed as recommended instead of the textured that I use for PETG.
The PLA stuck so well to the heatbed that it had to be scraped off and still left this ghost outline. The gcode is from the Prusa slicer (PLA, 215 nozzle, 60 heatbed). Has anyone seen anything like this?
RE: PLA sticks too well
I have seen similar but faint outlines like that on my smooth sheet too.
Like you I use the textured one for PETG and the smooth for PLA ( default temps). The outlines did not completely disappear with a good dishwashing soap either. On the other hand, I had not seen a change in adhesion so I looked at it as just a cosmetic issue.
A few months later when soap washing did not seem to work well anymore I used acetone (smooth sheet) and the marks pretty much disappeared.

Not unusual. Doesn't have any impact on the sheet's performance.
