    I have a variable speed spindle motor (pot controlled not PWM) connected to grd and pin 13 on the UNO.
    Is there a way to post just M3 on the open builds controller to turn the motor on and just M5 to turn it off
    rather than having to send G0 etc. first??
    I have a relay circuit connected to the Uno to turn the spindles power supply on and off.
    Thanks.

    GRBL by default just need M3 S1000 (if $30=1000) - no need for G0 first
