@dc42 said in Duet 2 wifi - Reprap 3 MPU fan thermal control:

I have my electronics cooling fan set up to monitor both the driver and MCU temperatures, with a temperature range of 45:55. That way, the fan will start to spin if the MCU temperature exceeds 45C, and it will be full on if either MCU temperature exceeds 55C or there is a driver overheat warning.

@dc42 can you please share the code. Thanks a lot.
