hi, all of the sudden I am having problems with the top layer of my prints, I do a lot of coasters and plaques, now the top layers are coming like the photos show, rough, with a lot of bulge and marks, how can I fix that, what am I doing wrong, is this the printer or something to do with the slicer settings?, its happening with different brands of PLA, I have the Bambu Lab P1S, thanks
