Servo Taig from Supertech

Does anyone here have any expereince with the Taig based CNC mills
sold by Supertech? What about Supercam software?

I have the Servo system on the way.

Questions;

1. The controller is an EMC-XYZGS-BX. Is this proprietary? Can I use
things such as Bobcad and Master5 with this controller?

2. How much should I worry about the "tuning" of the servos in the
future? Supertech is setting it up initially, so I assume that it
will work out-of-the-box, but what about later?

Thanks for any input.
