Hi Ed,

>>I have a small, homemade 4-axis CNC milling machine made from surplus precision ball-screw linear slides with stepper motors.

I am very impressed.

CAM software can be expensive, there was at one time software available freely, such as "CNCsimulator" but find all links to that now dead.

I will e-mail around to see what is still available.

I would have no problem, if you like, to create path info for you freely, just a need for me to know your available tooling.
