Top layers invariably have "melt" dots along with overhangs as the model grows in size
I have been struggling to determine the source of the "melt" dots that you can see in the attached image within square marked 1. They are pronounced on larger prints. On small prints, the dot is much smaller, but always there at the retraction point. For whatever reason, the print is great in the center of the model, it's just that as you get to the boundary, it all goes south. I'm effectively using OOB settings in PrusaSlicer-2.2.0.
I don't really know when the behavior started. I was getting great prints when I first assembled my MK3S. I have since added the MMU2 to the printer. Perhaps there was a setup area that I missed. This is starting to be a problem as I am trying to print involute gears and the 1mm overhang that I'm getting is affecting the mesh of the gears.
PLA; 205 extrude temp; 0.2mm layer height; 5 top layers; 20% infill; defaults for Retraction
