Hello!

I'm nearly done with the hardware of my CNC tube cutter and I'm getting into sorting out Mach3 settings and selecting a good CAM program.

But I'm a newbie and still learning a lot.

What would be the best program to make g code for this type of machine? the tube is in a chuck so with every tube radius change the number of motor steps changes per millimeter.

Is it correct that entering the diameter in Mach3 only influences the feed rate?

Is it correct that the G code will send out signals in degree's in stead of millimeters?

There are so many CAM program's What program can create the file type I need and is affordable/easy to use?
