Stepper Motor Control??

[EddyCurrent]

I certainly don't want to garner any animosity or disrespect by using the word "toy", but the reason for my comment was twofold

1. From your comments I assumed you wanted the cnc machine to do the required job of making guitars. I have made quite a few guitars among other things and I know the amount of rigidity and spindle power that is required to do the job and in a timely manner. You could build a lighter machine that would probably work but you might be dissatisfied with the result so I'm trying to encourage you to avoid that.

2. I'm assuming you want version 1 of the cnc machine to do the job rather than embarking on a version 2 later, why do you think others have had to build a version 2 ?

If you want to build a cnc machine for learning purposes then Neale's reply might be more applicable. Best of luck either way.

A search on the internet for "cnc schematic" produces loads of hits.

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.
