Thanks to CNC COOKBOOK pointing it out I now cant get it out of my head. It looks like one hell of a deal for around $2000 fully loaded, but I'm curious what I would need to actually use it.

I have a G540 with 3 steppers and I'm electronically challenged. As I understand it I would have to buy a servo separate, encoder, driver, bob, PS, and figure out how to add another PP to my control computer... Is that right? I'm thinking this is what its needed because the open driver on my G540 cant run a larger servo???

I have a friend thats good with computers that could help with the pp, but how would one configure the computer (or mach3) to send signals to the 2nd pp only for A axis moves?

Or am I way off?
