    on the left side, under "Out Mode" "Monitor" is selected, right?
    if yes, please post a screenshot from smc

    The settings looks fine for me. you can try to change Fpid to lower the calculations and see if that would do something. You can also try an older smc version and arduino sketch.
    i also had some problems with a chinese arduino and changed to a original UNO R3
