I have a Mk3/4 board with an Output Board. I have connected the spindle as shown using the instructions on your website. All is working very well.
I don't seem to see a way of having both the spindle and coolant connected and controlled with Mk3/4 and the Output Board, am I wrong?
As a reference I followed this instruction link:

Thank you
