Hi Jarrett,
I sent this to you in an email also, but if you could tell us a bit more information we will be able to help figure out the problem.
  • What programming language are you using?
  • Are you using the included PWM cables, or other ones that your team had previously?
  • Have you tried calibrating the controllers or doing a reset?
  • Does the issue happen as soon as the power is turned on or only after the robot is enabled in the driver's station?

Please also check that power and motor connections. If motor and power connections were swapped, motors could spin uncontrollably regardless of the robot state.

If you send us a photo of your electronics setup, it might be easier to diagnosis the problem. Also if you would prefer, we can talk you through it over the phone.
You can reply to the email I sent you or send me a private message here on Chiefdelphi.


Thanks,

Greg
