    Re: spindle speed fluctuations and not max speed

    good evening mactec54. Today I tried to measure what you advised me, but I have no tension anywhere. Which cable exactly should I measure? I measured 10v and ground. voltage but only max 1.2 volts :/

    You should only be measuring the output from the Breakout Board, not any cables, if 1.5v then you have a problem with the setup in the control or your Breakout Board is bad, these Breakout Boards have not been very good and most have this same problem with the spindle speed output voltage

    Have you connected the 12/24v to the Breakout Board , 12v is normally best
