[SOLVED] Any ideas what causes this in overhangs? (lemmy.world)

When I do an overhang test, I always have this problem at about 35°. Does anyone have a suggestion what could be causing it?

Slicer: Orca
Layer height: 0.2mm
Infill: 0% (this has improved it a lot, I think the infill was causing bulging)
Outer walls: 2
Overhang speed: 10 or 20mm/s (both look the same)

Solution: I mistakenly thought overhang speed in Orca was based on overhang angle, it is percentage instead (which makes much more sense for different layer heights). My 10-25% overhang speed wasn't set to slow down and that must translate to about 35° at 0.2mm layer height. I now have it set to 30mm/s and it now looks great 👍 And sorry, I was wrong when I stated the overhang speed 😅

Thanks. I'll experiment with temperatures first but I've got some different filament on the way too as it happens, so hopefully I'll manage to escape the problem one way or another 😁
