      Tried to search for it, but either i searched for the wrong stuff or it haven't been asked bedfore.

      But how to go around to assign "Fan2" as a thermostaticly controlleded by the MCU?

      In RRF2 i have "M106 P2 T45:65 H100:101:102", but from what i recon this won't work on RRF3 right? Or am i overthinking it?

        You need to define an extra sensor for this (see M308) and then map it using the H parameter of M106. In RRF3 the M106 H parameter specifies the sensor number and not the heater number. The sensor type should be mcu-temp and/or drivers.

            Yeah that's what i thought, but i got a little threw off course since i have no "P" parameter, i guess it "P" just ain't needed since mcu-temp and/or drivers are virtual heaters?

            Doing the intial leap to RRF3 now so i'm still a little shaky on the "new stuff" in regard to RRF2 🤕

            So if i do the following:

            M308 S100 Y"mcu-temp"
            M308 S101 Y"drivers"
            

            Then i can use:

            M106 P2 T45:65 H"100":"101"
            

            Or am i missing something?

              Yes. See the RRF3 example here: https://duet3d.dozuki.com/Wiki/Mounting_and_cooling_the_board?revisionid=HEAD#Section_Cooling

              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 as thermistor on pin e1temp for left stepper
              M950 F2 C"fan2" Q100 ; create fan 2 on pin fan2 and set its frequency                        
              M106 P2 H2:3 L0.15 X1 B0.3 T40:70 ; set fan 2 value
              

              Creates sensors for the driver overtemp flag and the MCU temp reading using M308 as S2 and S3. Creates a fan port for Fan2 with M950. Then creates a fan command to link those sensors to fan2 with a temp range of 40-70 using M106.

              Note that the MCU temperature must be calibrated to get an accurate temperature reading. See here: Calibrating the CPU temperature

              You'll get there. I assume you've seen this? https://duet3d.dozuki.com/Wiki/RepRapFirmware_3_overview

              Between that and the gcode wiki you can get a lot, but some of the more esoteric things such as this require an example and explanation since they aren't really intuitive. But that's what we're here for.

                Yeah i did the M950 already so that's all nailed, but i didn't see that first link with the how-to before. That sure helped, thanks! 😅

                Yeah some stuff migrating to RRF3 is a little hard to get your head wrapped around, but i think i got my config.g and homing files more or less gtg now. Sure as h**l would be even more dificult without the forum to lean on 🥵

                  Physically what PIN of the board should I use in this example to connetc the fan? The Fan 2 pin?
                  this one:

                  In case would it be possible to use other pins? FAN0, FAN1 and FAN2 in my board are already busy....

                    I'm using FAN2 yeah, if your using RRF3 it's quite simple to assign it to something else to. If your not using your second heater port for example?

                      yes! just a question: the fan I want to control is a parallel of three fans, one above the Duet, one above the Raspy and one in front of the Mosfet... I'm starting to think that maybe the total impedence of the parallel could be too low and could damage the board... is it possible?

                          uh I don't know exactly, they are 2 120mm fans for the 2 boards and a 40x20 Noctua for the Mosfet... all of them 12vdc

                            @the_dragonlord Check the labels on the fans to see if you can find some specs.

                            The biggest thing will be to make sure you're not drawing more current than the single fan port can handle.

                            We recommend no more than 1.5A continuous current draw from each fan output, although up to 3.5A for a few seconds while the fan starts up will not harm them.

                            I'd be most concerned with the large 120mm fans.

                            12vdc and the fans wattage would give you the current for each. add them up and see if it's more or less than 1.5A.

                                the two 120mm fans declare to need 0.19A each, I don't know about the Noctua but I don't think it's more than the 120mm...just to overestimate the load let's suppose a load of 200mA each, putting them in parallel I'll obtain a total load of 600mA wich is more than safe for the board... am I right?

                                    1. I always see the drivers temp=0

                                    47034135-c719-43ef-b08a-a6872df7cc8b-image.png

                                    As you can see from my config.g I've setted 20 as trigger temperature for both of them but the fans only blips at startup and then doesn't spin at all....what am I missing?

                                      You've got the M950 in your first fan block uncommented, but then the m950 in the lower block commented.

                                      So I think you're being affected by this

                                            The drivers don't report a temperature, they report a flag for normal, warning, and overtemp.

                                            The MCU does report a temperature, and is why it is used as a proxy for general board temperature.

                                            If you want to add a temperature for the drivers, you'd need to add a thermistor to the chip.

                                            But generally, as long as there is some cooling, the drivers are highly unlikely to enter overtemp in normal usage.

                                              (I hope we get 4 or even 5 controllable fans on duet3mini - I wouldn´t even bother if only 3 or 4 can do pwm if the other 2 could be made on/off("bang/bang") via conditional g-code...)

                                                and how about the drivers temperature to 0?

                                                uh ok... so the two values of the T parms in M106 aren't one for the mcu and other for the drivers?

                                                  Yes they are, the mcu will function on temp basis to control the fan and the driver over temp still functions in a similar way, you're just not getting a temp reported.

                                                    M106 P2 H-1 S1

                                                    This is the result of the M98:
                                                    Cattura.JPG

                                                    And if I send M106 P2 H-1 S1 the fans spin at 100% only for the time setted in the B parm of M106

                                                    But making experiment I've noticed somehing very very strange...I've increased the blip time like this:

                                                    ; Fans
                                                    M950 F0 C"fan0" Q500 ; create fan 0 on pin fan0 and set its frequency
                                                    M106 P0 S0 H-1 ; set fan 0 value. Thermostatic control is turned off
                                                    M950 F1 C"fan1" Q500 ; create fan 1 on pin fan1 and set its frequency
                                                    M106 P1 S1 H1 T50 ; set fan 1 value. Thermostatic control is turned on
                                                    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 as thermistor on pin e1temp for left stepper
                                                    M950 F2 C"fan2" Q500 ; create fan 2 on pin fan2 and set its frequency
                                                    M106 P2 H2:3 L30 X100 B10 T32:70 ; set fan 2 value
                                                    M950 F3 C"e1heat" Q500 ; create fan 0 on pin fan0 and set its frequency

                                                    well, I put my finger over the MCU, when it reaches the 32°C the fans start to spin ato 100% spin for 10 seconds and then stop...it's a mistery for me

                                                      The drivers don't give a temperature readout. The 'drivers' virtual sensor will read 0 when the drivers are not overheating, 100 if a driver is warning that it is hot, and 130 if a driver has shut down due to overheating.
