DeskProto is a 3DCAM program that can be used to create 3-axis, 4-axis, and 5-axis CNC milling machines. It can import 2D vector (DXF), SVG, AI, EPS, EPS, AMS, AI), 3D geometric (STL, DXF), bitmap (any digital image), and calculate CNC toolpaths for the design. Finally, it can export a toolpath file to the machine you have selected - there is a long list of supported machines. DeskProto is available as a free, entry, expert, and multi-axis edition. Hobbyists can purchase a low-cost hobby licence for the last three.
