Hi guys, I am trying to control a Stepper Motor using a NI 6008. I've done a little research and I know that there are some problems using the 6008 with a stepper motor, but for my project it should work just fine. What I need: A VI that will control a stepper motor and rotate the motor to the angle typed. The motor has an increment of 7.5 degrees. I construct a VI that will rotate the motor to the desired angle everytime I press the button "GO". But It only works for the first time that I press "GO". The problem: After the first iteration, if I press "GO" again, it won't apply voltage to the next pin, because it restarts the loop. And that causes the motor to go crazy. The solution: (that I am not sure how to implement) Make the motor go back to the initial position when I press the button "RESET". In the case, everytime I want to change the angle, I just have to press "RESET" and then "GO", and the motor would go to the desired position. Or even better: when I press the "GO" button the motor would automatically go back to the initial position, and then go to the desired position. BTW: I would like to go back to the initial position without having to do a 360 loop. I know how to do that. The VI that I created is attached to this message. Please HELP. Thanks.

Hi, Gear, I tried to drive the step motor by an pre-definded array and rotate it by each step. Hope it help.
