Dialing in overhangs
I recently got and assembled my Prusa Core One+ and it works great... for the most part, my current biggest issue is overhangs, every time my printer does gradual angle overhangs they curve up and the nozzle runs into them, and the underside looks ATROCIOUS, my Ender 3 Pro had better 45 degree angle overhangs. Any advice on fixing dialing the settings in?
RE: Dialing in overhangs
It happens with all of my filaments, from my Inland PETG to my overture PLA and I'm about to test out my new Overture PETG
Please show us a picture of the problem.
Cheerio,

FWIW, most of my flat overhangs are a disaster, or at least a bit ugly. I think the slicer could do a better job, but the answer is usually supports, or redesigning the part with angled transitions rather than flat overhangs. Bridges are better, but I think they could be vastly improved with a few more bridge-specific settings in the slicer.

Only way to control this is by properly calibrating your filament for both temperature and max volumetric flow. The built in PrusaSlicer profiles are really just a best guess. Some types of plastics even behave differently across colors. For most overhangs that are at a steep enough angle to cause problems, I paint on tree supports.
RE: Dialing in overhangs
Absolutely true regarding colors. Even in professional practice with injection molding machines, it is similar. For example, white PC worked perfectly fine, all you had to do was pour green PC from the same manufacturer and problems started when the moldings stuck to the mold and it took several hours to set the parameters so that it started working. And then another color change came and the torment began again. Unfortunately, this is the fate of everyone who tries to somehow force plastics to behave the way you want.
