Does anyone have any opinions on what is the best CAD/CAM software for a CNC milling machine? I am building a 3 axis gantry type machine driven by steppers. The motors will be controlled by Pic List "Linistepper" drive boards.

I intend to be milling PCBs as well as nonferrous metals & plastics. Both the metals & plastics I expect to be fairly complex 3 dimensional shapes.

I will be using a pentium based PC running XP. Cost is an issue, but getting a good package is more important than outright cost.

Your advice would be most appreciated.

Tony.
