Solved Laser Safety Switch

[chimaeragh]

I am making a magnetic mount for a diode laser module to be attached to my CNC router. Since the module will be held in place by magnets only, I was thinking of implementing a measure that will cut power to the laser and pause/halt the machine in case the module falls off during operation. I was thinking of integrating pogo pin connectors into the mount to act as a sensor when the module is attached and detached.
This would only be enabled during laser mode and disabled after switching back to CNC mode.
What would be the best way to wire and configure this on a Duet 2 Wifi with firmware 3.4.5?

@chimaeragh You would define it as external trigger and use daemon.g or your own macro to control it. The motion would stop after the current motion has finished. So it would be good to chop straight moves in shorter portions. (segmentation: see M669 Txxxx)
It would be good to switch off the 24V power too when the contact fails. (heater port in your other thread)
