I am putting together a cnc based guitar pickup winder and need some help with power. The winder has 2 stepper motors - one rated at 3.4v / 1.68a and the other at 2.8v / 1.68a

How do I power these motors? Do I need 2 power supply's for the different voltages?

Also any recommendations on good, cheap, easy to set up drives and breakout board would be appreciated.

As you can tell, I am very new at this. If this project goes well I am going to build a cnc for guitar body's and necks.
