Sorry, just realized I never stopped back in this thread to let you know the end result. It was indeed a programming issue. We had been telling the motor "If this button is pressed, you're ON. Otherwise you're OFF." But then, with a whole different button, we were telling it to go the other direction when pressed, otherwise off. This confused the motor in case two, and it was trying to be both OFF and REVERSE at the same time. We fixed it with some nested select statements in LabVIEW.

Thanks for the insight everyone!
