Sensor for driver temp RRF3.1.1

[AlexLin]

Hi
I'm using RRF3.1.1 on Duet2 wifi and have this in my config.g:
M308 S5 Y"drivers" A"Drivers"

But the reading are always 0.0C...it works fine for mcu-temp.....

Have I configured it incorrectly?
Cheers
Alex

That's correct. The drivers don't report their actual temperatures, just normal, warning, and shutdown. RRF maps these to 0C, 100C, and 130C. The idea is that you can use the warning to turn on a thermostatic fan.

It's good for me. It's normal because it's report only warning and error flags

OK that is fine then when it is a warning 100C will trigger the fan
