[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 😅

I believe that if your layers are printing fast enough, the softer material would bend according to where the top layer is printed.

Sorry, I didn't follow that. Top layer of what? Not the actual top, top layer right?

I meant, the next layer directly on top of where your deformed layers begin.
