beginning steps to building my cnc

[njhussey]

Most of the electronics are modular so all you do in effect is wore between the PC and the breakout board and that breakout board and the drivers and the drivers to the steppers...a bit simplified but that's the gist. As Maryin said you can get an old PC tower case and put all the electronics inside.

Have you read any of the threads I linked to in my earlier post? You can see the components as they go together. Also shows you that mist builds evolve over the build thread from the initial design :)

Yes those are how the components basically go together although for the X axis you'll have one rail and one ball screw on each side of the table like you've sketched.
