      I finall ytook the plunge and converted my machine to RR3 (complete config wipe and created a new file to get rid of old gunk), but I cannot get my chassis fan to work properly.

      In RR2 i did this:

      M106 P2 I1 H100:101 T45:55 L0.3

      After a lot of reading i configured RR3 like this:

      ; Heaters
M308 S0 P"bedtemp" Y"thermistor" T100000 B3950 R4700        ; configure sensor 0 as thermistor on pin bedtemp
M950 H0 C"bedheat" T0                               ; create bed heater output on bedheat and map it to sensor 0
M307 H0 B0 S1.00                                    ; disable bang-bang mode for the bed heater and set PWM limit
M140 H0                                             ; map heated bed to heater 0
M143 H0 S120                                        ; set temperature limit for heater 0 to 120C
M308 S1 P"e0temp" Y"thermistor" C7.060000e-8 B4725  ; configure sensor 1 as thermistor on pin e0temp
M950 H1 C"e0heat" T1                                ; create nozzle heater output on e0heat and map it to sensor 1
M307 H1 B0 S1.00                                    ; disable bang-bang mode for heater  and set PWM limit
M308 S2 Y"drivers" A"DRIVERS"   					; configure sensor 2 as temperature warning and overheat flags on the TMC2660 on Duet
M308 S3 Y"mcu-temp" A"MCU"   						; configure sensor 3 MCU Temp

; Fans
M950 F0 C"e1heat" Q22500                              ; create fan 0 on pin fan0 and set its frequency
M106 P0 C"Print" S0 H-1                             ; set fan 0 name and value. Thermostatic control is turned off
M950 F1 C"fan1" Q500                                ; create fan 1 on pin fan1 and set its frequency
M106 P1 C"Heat sink" S1 H1 T45                      ; set fan 1 name and value. Thermostatic control is turned on
M950 F2 C"!Fan2" Q500                                ; create fan 1 on pin fan1 and set its frequency
M106 P2 C"Chassi Fan" H2:3 X0.05 B0.5 T45:55                      ; set fan 1 name and value. Thermostatic control is turned on

      But even with DWC shoing MCU at 62C the fans are off. (My MCU is not really that hot, but i have not put in my M912 yet)

      So, where does my thinking go wrong here? (yes, I am using e1heater for print cooling. BerdAir and all that)

        Sooo, I completely miss-read the documentation for the X parameter. All good now.
