I've not seen a tutorial but then I wasn't looking for one. I'm not much of a programmer but it might be easier to modify an already existing program. A lot of people really like mach3. I can tell you that usb control for CNC is still experimental. I thought I saw a thread on it a few days ago. I'll see if I can find it.
