We have a simple but severe problem. Only motors connected to port 1 and 10 follow commands, We need 6 motors for the wheel drives and we really need the other ports to work. How do I get them to work?
Motor ports 1 and 10 have a speed controller built in to the Cortex, meaning you can plug a 2-Wire 393 Motor into those ports directly. To use motor ports 2-9, you must use a Motor Controller 29 between the Cortex and the motor.
