NibblePro is a free CAM application for turret punch press machines. It imports DXF drawings, allows tool assignment from a configurable revolver, and exports NC programs ready for AMADA punch presses.
v1.1: Auto-machining — automatic toolpath generation from DXF contours.
Features:
- DXF import with multi-part sheet layout
- Configurable tool revolver (.arw format)
- Auto-machining: holes, grids, SPEC shapes, slots, corners
- Punching, nibbling lines/arcs, hole grids, corner notches
- NC export (G-code, repositioning G25/G27)
- NC simulation with step-by-step navigation
- Split/merge nibble operations
- Available in Polish, English, and German

Windows SmartScreen may flag the installer with a "Windows protected your PC" warning, because the executable isn't code-signed with a commercial certificate (those cost too much for a free hobby project). The installer is clean. You can verify it yourself: the SHA-256 on the GitHub. To proceed past SmartScreen: click "More info" →
