Well I have decided to build a cnc machine now what? I plan to use Mach 2 or 3 software to control it. I would like to build a small say 2'x2'x6" to start but I want to be able to do wood and metal ( metal to make parts for bigger system in future) I will be doing 3 axis for now 4,5,6 with bigger machine. So the big question is what size motors what motor controlers Plans and a material list? I really dont get how the threaded rod is suspended and driven backlash and loaded nuts etc.. Could someone explain the construction of a nice cheap gantry system with pics for the Newbie PLEASE. I want accuracy at a fair level I really dont know what is considered good in accuracy .001 is what I would like to get or better.
Thank You
