    I got the 400w spindle in my kit so its got a PWM Speed Controller dial to control the speed of the spindle. In stead of using the dial, can this be connected and controlled using the BlackBox unit?

    all information i can find only describes connections for a VFD Inverter.

    Pictures / datasheet / manual for your spindles controller and what it needs in terms of a PWM input would help us check

    Suitable for the 5v 1khz PWM output straight out of Grbl then. Should work. GnD and PWM is labelled on the Toolhead connector. M3S??? Where ??? Is a number between the values of $31 and $30 (0-1000 in default config)
