First Build

I am building my first cnc. It is a fixed gantry design with ball screw x and y. The z is a 1/2"-20 threaded rod. The question I have, is this motor and controller setup a good one. Here is the link
【German Ship】3 axis Nema23 stepper motor 425oz-in Dual & Drivers DM542A CNC kit | eBay
I realize the motors are probably overkill but I am looking for opinions.
Thanks
