Hi again, no animosity taken.

Has previously stated, I am not a novice at CNC, my first CNC was a converted "HOBBYMAT BFE65" desktop milling machine, this was about 12 years ago, may be more. I fitted Steppers to this machine, X.Y & Z Axis, it ran on MACH3 and a Desktop PC, a DELL if I remember right. It worked perfectly well, only used it a few times, small parts made. I was then given an offer I could not refuse. I was offered double the money I had spent, a no brainer at the time, as my hands and skeleton where then OK, and I could still use hand tools, since then of course Arthritic has set in in both hands and I now find it difficult to use them, with hindsight I wish I had kept the machine, built another with the money I made, and simply learned more about programming etc; then I might not have to ask many questions.
