Hi I looked at the MX4660 and you still need a motion controller so that's adds up. The MX at 60V and 6A is attractive for bigger motors then you have. 60V is very attractive. The 3D printer boards are a BOB, motion controller and machine controller, computer in one.

Don't need a computer to run either as its a computer by itself. Front end (GUI) is different to a CNC GUI but can do the same job with lots of options....I'm wading thru this stuff at the moment So you get the whole deal + 4 drivers for $108USD Peter
