Yes, I'd thought about that already.

I'd use this:

M9 (to shutoff running coolant)
M7 (to start buzzer - simulated "Mist")
G4 P3 (to pause for 3 seconds)
M8
M30


I still have a question about the voltage and where to connect the actual wiring for the 12v buzzer?

+12v comes from your power supply through the relay contacts and to the buzzer then to your 12v supplies 0V. The coil of the relay is operated by the pin you set up for your M7.

I think I get it.

You're saying that I just connect the 12v positive wire from the power supply to the "VCC in" pin, connect one end of the buzzer to the NO pin, the other end of the buzzer to the ground of the power supply and use Mach to toggle the relay?

Not familiar whith that board but sounds right as long as the VCC is actually the common pin of the relays contacts.
