Duet 3 - over-temperature alarm

[CelloMike]

Hi,

Is there any way using the Duet to set up a temperature sensor to give an alarm or shut down the machine above a certain temperature?

I have my CNC in an enclosure, and I've added a PT100 inside there to monitor the temperature but I'd like to be able to leave it alone and have it set off an alarm or stop machining if it gets too hot in there.

Is this something DWC is capable of?

@cellomike you could use a daemon.g file to monitor the temperature. If it gets too hot then you could use M25 to pause the print, then M81 to turn power off if you are controlling the PSU.

@dc42 Thanks! I hadn't come across the daemon.g file (my firmware download didn't come with one)
Looks like this will work - do you have any guides to how the syntax and variable names etc work? I've not been able to find much documentation about it
