I think I have found my problem(s)
I had neglected to load the MB2 profle when starting Mach 3. ( I had missed this step somehow. ) I only noticed it when I watched cncrooms's u tube video in Thai.
The manual seems to be wrong as well... Output 1 drives the SPD output, so I will use that to start/stop the VFD via a 24V relay.
Output 2 is Coolant ( I think ) and Output 3 is Mister ( or vise versa )
Just waiting for a 24V relay to arrive and I can try it.
The diagram above appears to be wrong as well.
