What are the power requirements of the stepper motors you have? (careful -
they may not all be the same).

You should see a rating of the number of amps, or the resistor winding ohms
- you need to know that before you can select a stepper motor controller as
some steppers have a high current drive.

Since this is a non-functional 3D printer, perhaps you can even look and
see what chips they used to drive these stepper motors
