Controlling multiple steppers - How Best?

MarkT:
5 wire means unipolar only really. Normally you'd use ULN2803 or similar to drive
widings to ground and have the common wire connected to the motor supply.

For multi-axis control there are projects like GRBL, although these usually only
support step+direction bipolar drivers.

If your motors are quite old they won't have NdFeB magnets in them and probably
have quite modest torque specs, note.

Modest, hell, they are positively anemic. 7 in/oz 24v. Better than nothing, but not by a helluva lot.

I have some ULN2003 driver boards coming over on a slow boat from China. Don't know how they compare to ULN2803.

Right now I'm just playing around. When I get serious, I'll get some serious steppers.
