Don wasn't suggesting that you connect two
motors to one controller.
He was suggesting that you connect two
controllers to one DSC PWM port with a PWM Y cable. This is common and accepted practice.
Of course, if you did this you would have to connect the encoder to the cRIO (via the DSC).
Then, you would read the (single) encoder, use it to compute the appropriate output command (using PID or other control algorithm in your cRIO software), and send the computed command to the DSC PWM port... and the Y cable would send the signal to both motors.

However, we've decided to cut back to one motor in order to be able to use the built in CAN functions for positioning.

I'm not sure if there's any accepted and field-proven way to use one Jag's built-in position controller to sync properly with a second motor.
