Without setting the Encoder lines, the Jaguar will not be able to report the position nor speed.
We drove the wheels in speed control, voltage control and even spinning by hand, and we did have the encoder lines setting correctly set. The problem was resolved by replacing the encoders with a different model, as of yet we have not determined precisely why the older encoders did not work, as I checked them on the oscilloscope and they were most definitely feeding the correct signal in to the Jaguar. We also re-used the wiring harness when we switched the encoders, in addition to beeping them out with the multimeters, so we know the wiring is/was always intact. This one is a mystery....
