Robin2:
I find it hard to understand how you are thinking of using an L298 if you had read stepper motor basics. Use a Pololu DRV8825 stepper driver. The Pololu A4988 and the BigEasydriver would be struggling with a 2 amp motor and the DRV8825 has a little more headroom.The title of your Thread is also rather irrelevant to your problem.

the reason on why im still using the L293b is beacause were i live it aint easy to get a pololu driver, it will get me a month to get it, and i need it quick, so i guess i'll try again with an L299n.
