What stepper motors and drivers to use

[matias_r]

Hello I am new to this. I want to build a cnc router for creating carvings mostly in hard wood like oak, maple etc. The dimensions I had in mind are 4' x 8' that way I can fit a sheet of plywood in it. I am not sure what motors or drivers to use. My design so far would be for a direct drive to the lead screw. If anyone can point me in the right direction as to what I need for the drive system on this I would appreciate it. Thanks
