Laser Coolant sensor auto Laser protection

[CNCModeller]

Hi All,
I've got a pulse generating flow sensor in my laser tube coolant line and it's registering as a fan 2 speed in DWC.

My question is how can I disable the laser or pause the cutting operation if the flow drops below a certain threshold TBD.

I was thinking perhaps daemon.g could check the fan speed and then if the speed is too slow trigger a warning. If the laser is running a job, it'd pause the cutting operation, sound an alarm and wait for user input.

I'm also going to embed a temperature sensor in the coolant tubing with the idea of doing something similar for coolant temperature. And above the cutting bed to detect a fire .

I'm assuming I can pull the speed and relevant temperatures from the object model?

Any thoughts or useful example code snippets would be much appreciated!

My first foray into daemon.g, wish me luck

All the best

Am going to use the laser setup here as a template...

Will report back on how I get on.
