I think when you buy his plans it only covers that basic plan. Not sure I never bought one. But I am one of the guys that have copied his idea and built a machine from what I saw on his page. He even put a picture of it up on his page. He has since then taken it down. Must of made him look bad, becouse I did'nt buy his plans. He calls me a CNC PARROT. LOL. I have a picture of it on
my site . Its under photo gallery, go check it out.
As far as the stepper motors, controllers, and software I think you will get a ton of info on that stuff here on this site... There are some very smart people here who have "been there done it." You will get a mix of differnt ideas here instead of a onesided ideas there..
