Re: Jaguar Issues...

seen this before! ..... we had the same problem last year while using a CAN bus and a Jag for position control on a swerve drive. You need to find a way to flatten the voltage spikes. What worked for us was to apply a 20msec rate limit to the position request to the Jag. As a back-up we came up with a function (tied to a joystick button) to save the encoder readings, disable the Jags, and re-enable them.

At what rate are you making the speed requests? The older IFI controllers ran at something close to 26msec.
