    i have to setup all values to the same later but fot testing it works !

    so all motors moving with the test values or in manual mode as they should !

    BUT in Simtools Engine i have Problems with COM7. these 2 motors doesnt work as they should they randomly go up and down ... i dont know what it is: config for test:

    all the same with different Axis :
    Interface 1: [A<Axis1a>][B<Axis2a>] works fine
    Interface 2: [A<Axis3a>][B<Axis4a>] works fine
    Interface 3: [A<Axis5a>][B<Axis6a>] does not work !

    test with roll and Heave:

    It is easy to miss and many of us have had similar experience at some point in our projects, which is why it is good to have an active community to bounce stuff off.
