cd rom cnc machine not working

So I tried to make a cnc machine with an arduino uno, an easydriver and stepper motors according to this https://www.youtube.com/watch?v=RFo5MKSrM-k i almost have no experience in electronics. and the machine isn't working. I have two ideas why it isn't working it according to what I have searched. It could be either my stepper motor drivers are burned out or I have wrong wirings on my easydrivers. On the wrong wirings part, I may have soldered the wrong wires on the wrong motor coil but im sure that the motor coil that i soldered onto the pins are a correct pair. So I'm not sure what's the problem of the machine

Have you tried setting up the stepper driver potentiometer?

It would be almost impossible to fault find remotely with so many possible areas that may be broken.

I would suggest you disconnect everything. Check for free mechanical movement and start again - Just do 1 axis at a time and get it working before you press on.

You will then have the electronics from the second axis to help you with narrowing down the fault.

In general when fault finding start with SIMPLE things like power supplies.

The check control signals - An LED & 330 ohm resistor will let you do that.

The check output voltages to the motors.

Do one thing at a time AND only change one thing at a time so you can keep track of where you are.
