Guys thank you so much for the replies.
I tried some things out and when i unplugged the step motor cable from the 2003a unit. When i unplugged it, the 4 leds are blinking as crazy as the should do. But when i plugin the motor, only the first led is on ( as you can see on the pictures i posted ).
Since i dont know alot about electricity, is it possible that the stepmotor isnt getting enough power?
My setup is the same as the pictures, only the inputs are on 2,3,4,5, just like the code Tom gave me.
Thanks !!
