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)
Looks like the deformation is happening on the same layers where the overhangs of the number 35 are.
It starts just underneath actually, but it still could be related 🤔 Maybe I need a test without numbers.
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.
If 35° (or something close to it) is the slicer setting for overhang detection it likely changes the cooling/speed/flow settings. If that is the case you can set it to a lower detection value and maybe get better results or change the normal cooling/speed/flow to be closer so it isn’t as drastic of a change.
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 🤞
