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 😅

You may actually be right even though I thought I had checked this. Orca's overhang speeds are based on overhang percentage and not angle, I previously just looked at the number and assumed it was degrees 🤦‍♂️I will match the speeds for all overhang percentage ranges and see if that solves it 🤞
