      Hello everyone!
      I am using the 1HCL expansion board in order to control the step motors with encoders. I would like to use them also for cooling motors using funs. I saw the temp_0 pin in documentation for thermistor pt1000 and some output pins. But I can’t find any examples of this configuration. Can anyone help me make this configuration for cooling motors in a closed loop?

        @Kiryl What you mean is "fan" not fun 🙂
        I think you can configure the thermistor and a thermostatic fan like it's done for a hotend fan.

        M308 Sm P"temp? " Y"thermistor" T100000 B4725 C7.06e-8   ; define thermistor 'm'
M950 Fn C"fan?" Q500   ; create fan 'n'
M106 Pn T40 Hm   ; switch on fan 'n' by reading thermistor 'm'
