A fork of OrcaSlicer adding Z Contouring (also known as Z Anti-Aliasing / ZAA) — non-planar slicing that varies the Z height of each extrusion to follow the model surface, reducing the staircase effect on curved surfaces.

Enable per-object via Print Settings → Quality → Z Contouring.

Key settings:

• Z Contouring enabled — turns on non-planar extrusion for this object
• Minimize wall height angle — reduces perimeter height on shallow slopes (default 35°, set 0 to disable)
• Minimum Z height — minimum layer step size (default 0.05mm)
• Don't alternate fill direction — useful for some surface types

See OrcaSlicer's build instructions.

This project is a fork of OrcaSlicer by SoftFever and contributors, licensed under AGPL-3.0.

The Z Contouring feature is ported from BambuStudio-ZAA by zaalbarxx.

OrcaSlicer is built on:

• BambuStudio by Bambu Lab
• PrusaSlicer by Prusa Research
• Slic3r by Alessandro Ranellucci and the RepRap community

I take zero credit for this, this is 100% Claude. I don't even know C++. But it did such a good job, I'm putting it out there.
