Alpha testing — please read
This is pre-release software and it writes machine instructions. Review every program, use the built-in verification and simulation, set your machine up carefully, and run at your own risk. Stones & Sculpture accepts no liability for damage to machines, tools, materials, workpieces or people. The app asks you to accept these terms the first time it starts.
What it does
- Places an STL — or a grayscale image — on your stock: rotation, mirror, exact width or percent, offsets.
- Generates roughing, semi-finish, rest and finishing passes for a flat mill and a tapered ball nose, honouring the tool’s real shape.
- Verifies every move against the model and simulates what the cut will leave, before you export.
- Writes Mach3, GRBL or LinuxCNC g-code plus a printable setup sheet with zeroing instructions and times.
- 3D preview with a replay of the job, hover readouts, section view and gouge markers.
Free, as-is, community-supported. Found a bug? The setup sheet and a screenshot are the most useful things to send.
