finding CAM software
But that’s just the design phase. The next step is generating “toolpaths” in the form of gcode.
With 2D, that’s fairly easy - same as for a laser cutter. But for 2.5 or 3D, the free and low-cost software out there is limited, especially for Linux or Mac.
Only ones I’ve found in a brief search:

I've used DeskProto (€ 145, "Deskproto.com":http://www.deskproto.com/products/entry-ed.htm) which is pretty decent but does not run in a Windows virtual machine.
A free alternative is "PyCam":http://pycam.sourceforge.net/ . Development is slow, as is generating toolpaths. It's open source and can be used at no cost, so it might be worth spending some time on this and figuring it out.
