OK, thanks. I think that I will requisition a unused Windows computer, (1.5+GHZ) I will put in a new hard drive and install Ubuntu. from your live CD. I had a not as great luck with ubuntu as I had with Fedora, but this seems a special case. > > 2.

I will use Gecko G203v drives, which do seem appropriate for my use. My plan is to go in steps -- to first automate X and Y, and then Z (knee) and later my rotary table, for making gears and whatnot. My hardware experience to date includes rewiring my old TIG welder to use a BASIC programmed uprocessor called Cubloc, and I wrote a BASIC script that makes t a TIG/MIG/any other DC power supply. I would really like to buy a book that is a gentle introduction into CNC concepts. I know related math and linear algebra.
