You could do worse than trying FreeCAD . I would download the latest version https://github.com/FreeCAD/FreeCAD/releases see Pre 0.17 You should be able to open SCAD or CSG files with it and it has a Path Workbench for CNC. Note: The Path workbench is still under development. OpenSCAD files with minkowski requests can be a bit tricky, but worth a try. You probably want to set the preference in the OpenSCAD workbench to control the point where polygons get converted to circles. If there are no minkowski and hull requests then the FreeCAD version will not contain meshes ( STL type ) which I would have thought was better for CNC. If you hit any problems/issues report them in the FreeCAD forum https://forum.freecadweb.org -- View this message in context: http://forum.openscad.org/Using-CNC-Machine-OUTPUTS-How-tp21653p21654.html Sent from the OpenSCAD mailing list archive at Nabble.com.

I just export a .stl from OpenSCAD, then process it in MeshCAM. List of opensource options for it here: https://www.shapeoko.com/wiki/index.php/CAM#3D I did project (projection?) one file into slices which were saved (as DXFs?) which I then processed using MakerCAM (somehow I got them to SVGs I think).
