3 Axis Stepper and Spindle Control Circuit Diagrams

[Mad Professor]

Good Day All.

This is my 1st post so I do hope this is the right place.

I am looking at building myself a little cnc rig to drill holes in prototype pcbs.

I am going to need 3 axis and spindle control.

The rig it's self I am going to be building out of old broken printers and scanners.

The stepper motors I have collected so far are a mix of unipolar to bipolar, I don't know witch would be best suited for my rig.

I would like to be able to control the rig via my computers printer port, I am looking at using the Mach3 software.

I would be looking at building my own driver board, but as I have not worked with stepper motors before I am in the deep end.

If possible I would like to build a driver board that would support both unipolar and bipolar stepper motors.

Could anyone please point me the way to find some Circuit Diagrams that will be able to do what I am after.

Thanks for your time.

Best Regards.
