Hi all
I want the Duet3D to control a relay that will shut down my spindle on end project. If i could write a macro to start the spindle via a relay, then it would be even more cool.
I only looking for a clue if this is possible. And maybe where to look.
Best regards

Easily possible.
M453 that places Duet in "CNC Mode" allows specifications of which logical pins to use for controlling the spindle with standard M3/M4/M5. No macros needed.
For logical to physical pin mappings, see documentation at M42
For all this, start here:

@mikethk Let's go a little back closer to basics... what kind of spindle do you have on your CNC?

I got a 230v Dewalt spindle. So i guees i have to use some relays.

@mikethk Indeed, a relay or SSR are your only choices for that!
