I'm in the planning stages of building a cnc router . I like the idea of servos and have looked at the clifton cheap servos . --Next step is the power supply and driver . How many amps would be reqired to use four of these on a gantry design at 30 v ? ---Next question is the servo driver . I came across these and was wondering if anybody had had any experience with them ?

At $275 for four it looks like a pretty good deal ?
