Thank you all for the advice,
I am competent with electronics and have evan made my own PCB's, I just need schematics to go off of.
Candle, I like your advice about holding onto the driver, that makes absolute sense to me. I would greatly appreciate if you could provide me with a schematic for the interface. Do you have any cheap drivers in mind that would get me started with these large steppers? I was looking into building one that I found here
http://pminmo.com/ but I don't know enough yet to pick a good one. If I found some ok drivers online for cheap I could go that route as well.
I have read discussions about using "G-code" for machine control, I have decent skills with AutoCAD but have no idea how to go from .dwg files to G-code. Can someone advise me on this as well.
I guess I am actually asking for a crash course in how to build my own CNC and operate it. I have been reading alot of the forums but sometimes its hard to gleem the right information that I need from them.
