Problems with the cortex

I seem to be having a problem with my cortex I only have two ports that are work which is 1 and 3. It doesn’t make sense because I know that they both are on the same circuit. All the motors work we tested them. Could it be the motor controller that is not working.

First of all, have you programmed all the ports to do something? If you have only programmed ports 1 and 3, only 1 and 3 will distribute the allotted power to the plugged in motors. To test this effectively, ensure that all motor ports are programmed for the same power/joystick button, and test each one. If 1 and 3 only work, it’s not the program.
Secondly, you can check the motor controllers. Swap them around and see if some don’t work.
Let me know if you get anywhere with this.

We got it to work there was a problem with the program but we got it fixed thanks for the help
