Woffler,
Goto ports/pins >spindle, and set your spin CW delay to 2 seconds, in your M3 macro, have a user led like 2000, turn on, have a Brain watch that LED, when it turns on gothrough a timer with a 2 second ON single shot pulse. That will do your Stack Light Buzzer. In your M5 put the User Off for LED 2000 to reset it for the next tool.
