The CNC stepper motor driver schematics are very complex. Use the board file to create the gerber files if you want to send it out to get fabricated from a PCB .
The resistors are for protection against shorted wiring. If you short the wiring to your stepper motor you could burn out the stepper chip, as you could many other.
