Need Help!- adding one more relay

[electric2u]

i have a relay i would like to add, but don't know how to do it (program part). when the g code is done running i won't a relay to open (when it's running it closed) so that it well shunt the power to the cnc down (kind of like i walked away and fallen a sleep and i what it to turn off when it done) i know how to wire it, just don't know how to tell mack 3 to do this. sorry for the odd question but i'm an electrican and this stuff is fun to me.

thank you

Create a macro and call it at the end of the g-code. if the relay is wired to Output one, the macro should be

ActivateSignal(Output1)

or

DeActivateSignal(Output1)

Name the macro something like M555.m1s and put it in the macro folder. When Mach3 gets to M555 in the g-code, it should turn off.
