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 thought curling as well, but I would expect that on higher angles instead. Its easy to confirm this if you watch the print. The solution would be lowering nozzle temp and slowing down the print (well, not less than 10 mm/s). I've seen that also too much cooling can cause curling, but thats for super strong part cooling
