    Hi there, I'm exhausted on researching so I got a quick question…

    My 2 phase motor ratings are:
    Rated voltage=3V
    Current/Phase = 3A
    Impendance/Phase = 1 ohm
    Inductance/Phase = 4.3mH
    Degree/Step .9…

    I take it I set my dip switch on my DQ542MA driver to 2.84 peak amp/2.03 RMS setting. Correct me if Im wrong on that, if you feel Im safe to up it, please let me know. In the start up guide, smoothie says to set amp config to your motor settings, it gets me confused since driver setting are set lower than the 3amps, should I still set the config to 3.0?

    Thank You!

    Hi Aaron,
    You can always adjust the current (with the dip switches) after you try a couple practice runs to see how warm/hot the motors get, they should get warm.
    2.84A should be good.
    The Current setting in the smoothieware won't do anything for you as the DQ542MA drives are not digitally controlled by the smoothie board.
