Sorry, I'm unable to help you with your code since our team uses LabVIEW, but from your description, it does sound like you're using PWM. Also, there shouldn't be a need to use the USER button on the jaguars. Holding down the button for 4 seconds will reset the Jaguars to the default factory state, which shouldn't be necessary. I would recommend checking all of the things that were mentioned before and see if any of those fix your problem.
