Sorry for the ignorance inherent in this post but I'm really new to CNC design. I have the following parts from Techno Isel.

4 Voyager VB1 Belt Slide, 600mm travel, Servo Motor, 2 Carriage Type.
2 Transmission Bar and Coupling sets [ 2 bars and 4 couplings].
1 MP Servo Controller 4 Axis.
4 Servo Motor and Encoder Cable pair (16 ft in length).

I want to add z axis capability to my design using a company other than Techno Isel as their only option is too large.

My question than is: How do I incorporate an outside company's servo motors to be controlled by the MP servo controller I have from Techno Isel?

Any help you can provide me would be greatly appreciated. Thank you.
