Window Motor Problem?

[cdizzle]

Hi everybody,

Our team is trying to use a window motor on our robot using LabView, but when we program the motor to turn clockwise with one button and counterclockwise with another button, the motor spins perfectly counter clockwise. When we try to spin it clockwise, the motor twitches instead of moving smoothly.
At first we thought it was a jaguar problem, so we replaced it with a victor, but it still has the same problem.

Any thoughts on why?

Thanks,
-Team #2367
