  1. I am a new member, I just receive my first motor multiplexer for my lego EV3 brick.
    I downloaded the associated block to drive the board for my two motors and i builted a small program to test it, I found I can control my motor only in reverse direction and the braking mode does not work. I tried other motors, wires, and swap motor port M1 and M2 but it always do the same problem, I finally found if I program a forward direction for one turn and I help the motor to start turning, it will continu very slowly the full turn and than stop without brakink.
    I think my new board is not operating properly!, any idea to help me running my two motors properly with my new multiplexer?

    What is the power you are applying to the green connector of the NXTMMX?
