PEI sheet.. surface?
is this normal? 4 PLA prints into my new MK3S, and it is printing perfectly, and no "height" issues, have had perfect bed leveling, but the PEI sheed seems to already beginning to loose surface?
printed the Benchy / flute / marvin, so those are not this, and this was 1 headphone holder yesterday, so this is "one time" PLA on that area.
RE: PEI sheet.. surface?
I've heard that these are just small bubbles in the adhesive due to any number of things, most commonly removing prints before the bed has completely cooled. They should go away on their own, and they have for me over time.

These small air bubbles are quite common and there is nothing to worry about. At best, over time they will become smaller or completely disappear.
It is important that beds cool down before attempting to remove the printed parts. Then you avoid unnecessary damage to your bed.
