Stepper motors are easy
Use pololu drivers [
www.pololu.com]
Only 3 lines to control enable, step and directions
See ramps test code for a simple eg on how to move them [
reprap.org]
The pins are for a ramps board, but just change the pins to match what ever you use as a controller
The main issue is you will need some way to set zero position, as steppers do not know where they are on power on.
NB the steppers you have need to much current for full torque, pololu steppers are only really good for 1.7 amps, your steppers are 2.8amp
cant find the voltage..... or the torque specs
