godot-cnc-toolpath

Godot 4.7+ 3-axis tool surface (BarMesh). Raster/waterline toolpaths are archived on archive/raster-waterline-toolpaths — see ARCHIVE.md. We get the tool surface right before generating paths from it.

BarMesh (barmesh/)

CAD Z-up throughout:

File	Role
barmesh.gd	Node / Bar / BuildRectBarMesh — cutter locations (x, y, z)
tool_contact.gd	Ball-nose drop along tool axis −Z from a point above
draw.gd	ImmediateMesh; only Y-up conversion for Godot (x, z, y)

Play scenes/main.tscn (or Build tool surface) to watch the contact lattice drape over the part.

Units: metres in-scene; UI in mm. Play: MMB orbit, Shift+MMB pan, wheel zoom.

git clone https://github.com/DynamicDevices/godot-cnc-toolpath.git
