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.
