Yes, I have an enclosure, I tried numerous rolls of filament, including a brand new roll of Sunlu PLA. It bridges just fine, but it botches overhangs. I tried slicing with Cura just to see if it was a superslicer problem too. Also 2 different extruders, same results. Better cooling can't hurt, and I'll have to be more careful with CAD, trying to do gradual overhangs.
Realistically I could use supports but when the overhang is small I don't see why I should have trouble doing it when I can do a 2" bridge with no problem.
