Stepper Motor Dir/Step help program.

you got me there haha.
Yeah i mean moving simultaneously not in sync. haha what am i thinking when i said that.
Anyway i really cant think of a way to program the arduino for the 2 stepper to be moving at different step at different speed.
i kept going to for loop which in turn make it rotate both motor at the same time but the number of step for each is the same. now I am stuck.
