This is somewhat tricky. You can wire the step and direction inputs in parallel, and
as long as the computer port has the capacity to drive both, they should move in sync.

But, getting them in sync in the first place is tricky. You need some way to move one motor
at a time. What you would do is move both motors to the home position simultaneously.
When the first motor reahes home, you stop moving that one, and keep moving the other
until it also is at home. Then, you go back to moving both at the same time. I can think
of some fairly simple digital circuits that could stop the first axis when it gets to home.

Your machine needs to have some kind of joints so it doesn't bind when the motors
get out of sync.
