Short overview of how good the nesting capabilities of various 3D slicer are.
The task is simple: placing as many of these shapes on a 200x300mm printed as possible. Manual (quick and dirty for reference): 6 pcs.
Ranking:
- Ultimaker Cura: 7 pcs.
- human (me): 6 pcs.
- Orca slicer: 5 pcs.
- PrusaSlicer & BCN3D stratos: 4 pcs. By switching (for this particular part) from the worst (Prusa) to the best (Cura) slicer the nesting performance improved by a whopping 75%!

You can do that on the Prusa. The firmware let you cancel a part mid print but continue the rest.
