Chances are both these models use Steppers not servo's. If they do use servos they most likely will be Brushed DC servos and use 0-10v with maybe custom drives so do some research before buying if paying big money.
If controller is working then check out it's spec, memory etc and how it accepts G-code etc. If your planning on doing 3D work then often the controller is the weak link so paying for a machine with a working control is wasted money as you'll most likely rip it out.!!
They have the same name and model from what I can tell. What is different between them? Trying to learn from what you are spotting as to what is important and what is not.
