    How do I connect both the IOT and a 0-10v VFD to the Blackbox?

    Grbl only has one Spindle output so that would be an either/or situation for spindle control

    Unless you want to use the IOT relay for something else, then use the Coolant output (M8/M9 to turn it on/off)

    Actually I wanted to use the IOT relay for the spindle water pump so it sounds like I can just connect the IOT to the coolant output?

    :) Thanks for the extra details, it helps to have it

    Yes, according to the datasheet (attached), the IOT Relay can use a control signal of 3-48v DC (so the 24v Coolant output should do nicely)
    Haven't tested if personally, but please let me know if you have any issues
