If you are looking for a kit, try here...

They sell a kit with all parts already machined. You just need to assemble.

Sir,

It would be a help if you could describe the size, application, and general specifications of the machine you want to build. There are different approaches according to size, type of material you are going to cut, etc.
We could then offer ideas to fit your desired machine.

Need to have Step angle 1.8º, right?

i found this items

Motor 2 - Voltaje 12V Corriente 0.60A Torque 100N.CM (141oz/in)10.135g.cm Price $60
Motor 3 - Voltaje 12V Corriente 6.60A Torque 200N.CM (282oz/in) 20.270g.cm Price

wich is the Torque Value that i need to use in an nice CNC machine? 200-300 N.cm are ok or if i buy an bigger will be betteR?

Sir,

If you will email me, I'll send you pictures of the machine which I made; it uses readily available parts, steppers, Gecko drives, and any CNC controller such as TurboCNC etc. I think your steppers have too high a voltage; there are better choices.
