My CNC is built from 2 DC servo motors for X, Y axis and 1 stepper motor for Z axis.” Watch this video on YouTube. “Motor voltage: 24 VDC, 38 VDC (E-type).

The controller in question is a 4QD Porter 10 so an extra component is a DC-to-DC converter to provide a floating ground for the Arduino.

So long as the 0V rail is connected to the Arduino 0V rail, the positive rail can be any dc voltage – more or less that the Arduino, so great for 12V motors. And it is compatible with both 5V and 3V ...
