      heat and/or high currents are the common culprits with dead mosfets - usually a result of a short circuit somewhere.

      yes, you could wire pretty much any pin from a duet2 to the gate on a compatible mosfet and set it up as a fan with M950+M160. (pull up/down and series resistance as required, refer to the duet schmeatic for examples)

      however its common for the mosfet to fail before a fuse, as the fuse just isn't fast enough to prevent the initial surge from a short circuit, its there to prevent damage from overloading the board or wires in the event of a prolonged fault current. that said its still a good idea to add a fuse.

        Connecting a fan the wrong way round (i.e. wrong polarity) can also cause a mosfet to blow, depending on the fan.

          @dc42 Okay. I was very diligent to mark + & - wires when extending my wiring and tested continuity to make sure, which is why the first test was fine. I had it correct.
          Then yesterday all of the sudden all three just stopped working, nothing in the wiring changed.
          So... I have a question, why are the PWM fan ports not protected by a fuse? The only issues I have ever had with this board has been these MOSFETs . I love this board, but this is a serious Debbie Downer...
          And my question still stands, if I blew the MOSFETs then why do I measure voltage change when I toggle the F0 or F1 ports with M126? Last time this happened to me with a clone board, I read 0 volts, and I learned my lesson to triple check everything before plugging back in and powering up

          What are my options here?
          1.) Could this be a bad board that I could get replaced under warranty? Purchase was in April2020 via Filastruder
          2.) Can a [DueX2 expansion](https://www.filastruder.com/collections/electronics/products/duex2-and-duex-5-expansion-board[link text](link url)) allow me to get PWM functionality back?
          3.) Or could just this Expansion Board give me a couple PWM ports back?
          4.) am I missing something else that's affordable?????

            Your easiest option would be as bearer suggested above and remap a spare heater output as a PWM fan control.

            If you have already upgraded to RRF3 it's quite easy. You'll need to identify what heater port you want to use, find it's pin name, and then use M950 to define that pin as a fan. Then your M106 fan command can refer to it.

            I think when you extended the wiring there was either a short or a change to polarity that caused the mosfet to fail. Perhaps at a crimp there was a stray wire?

            They are, but as described the fuse is much too slow to protect from the initial surge. Fuses are meant to protect from a short circuit drawing too much current and setting something on fire. The mosfets are unfortunately delicate, so great care must be taken with fan wiring. And even when great care is taken, I've even seen fans from amazon that had the black and red wires switched. Peeling back the label to show the fan PCB revealed that the black and red wired were swapped at the - + silk screen terminals.

              @Phaedrux Okay. I just finished the upgrade to RRF3.
              So by doing this M950+M160, I will be able to have a layer fan that is controllable by Gcode? and a thermostatically controlled HE fan?

              Lastly, now that I've finished my RRF3.1 upgrade I get these 2 issues:
              1.) My inductive probe (NC) isn't stopping now when I do a G30 and put a wrench under it
              2.) and when I try to home X or Y, the head moves 5-10 mm and stops?

              Can you point me to a page that explains the RRF settings for these sensors? It used to be this in my config.g for RRF2.x:

              M574 X1 Y1 S0                        		   ; set active low and disabled endstops (To enable Z-endstop add "Z1 or Z2" after y
              M574 Z1 S2                                         ; Define Z to use probe. S2=Home to min
              
              and  for my ABL:
              M307 H3 A-1 C-1 D-1      ; (Duet3d method)  disable Heater7 to free up PWM channel 5 on Duex board for BLTouch
              M558 P5 H5 F600 A1 I1	; GLH8 EndstopABL, Mode P=5, StartProbeH=5mm, Speed=600mm/min, #probes A=3, Invert signal for Endstop I=1

                one of them if you have heater E1 unused; so I'd wire hotend to always on and layer to heater E1 output.

                  @bearer okay so that works for me! I've already moved my HE fan to always on.

                  Just for future plans sake, if I decide I need more PWM fans, can I get either the expansion board with 2pwm ports or a Duex2/5 and restore my PWM function with those?
                  Or does the main board damage prevent me from doing that?

                    can't say for sure but most likely that damage is isolated to the the mosfets for the fans (mosfets can be replaced, its a bit of a tight spot and some groundplanes, but with proper tools its perfectly doable; you can ask around locally or maybe https://forum.duet3d.com/topic/13875/community-repairs)

                    as for the expansion breakout i don't think you drive a fan off that directly. duex2/5 will be fine.

                      and  for my ABL:

                      M558 P5 H5 F600 A1 I1	; GLH8 EndstopABL, Mode P=5, StartProbeH=5mm, Speed=600mm/min, #probes A=3, Invert signal for Endstop I=1 
                      
                      

                      The issue is probably the inversion in M558 for the probe trigger signal. I1 is replaced in RRF3 by using a ! in front of the pin name.

                      I suggest you use the configurator to generate a config for RRF3 and then compare the output to your own to see the differences.

                        @Phaedrux that is the RRF Config output! Lol That’s why I was confused. I could have selected the wrong setting somewhere.
                        Thanks for the link, I’ll dig in after the kiddos go to bed.

                          @Phaedrux When you tag into E1 heater and Heater 7, just to clarify, I would hook up to E1 to the positive lead to fan. Then I would hook up "13) heater4" (as an example) pin to the negative lead of the fan?

                            Post your config.g then. Maybe you had RRF2 selected?

                            I'm not sure what you mean by this.

                              @Phaedrux I had a blonde moment, I can't use a normal 2pin fan can I?
                              I need a 3+ wire fan right? (sorry never actually used PWM function of fans before)

                              My artillery sidewinder specs:

                              Xaxis: homes at 0, left side (Panasonic GL8H optical NPN NC sensor)
                              Yaxis: homes at back, but 0 is actually at the front (Panasonic GL8H optical NPN NC sensor)
                              Z = Inductive ABL probe (Panasonic GXHL15A NPN NC sensor)

                              Lastly, here is my RRFconfigurator custom config.g for RRF3.1:

                                I had a blonde moment, I can't use a normal 2pin fan can I?
                                I need a 3+ wire fan right? (sorry never actually used PWM function of fans before)

                                to use with E1 output? you can use 2 pin fan. 3pin fans have tachometer for RPM feedback, 4pin fans have PWM input but i'd hesitate to drive the PWM input from a pin on the duet without doin some research

                                  @bearer okay so @Phaedrux said I can tag into the E1 heater for the 24v and then pick a heater pin on the expansion slot. My question is how do I actually physically wire this thing up?

                                  Red wire [from fan +V] ---> Heater4 (pin13)
                                  Black wire [from fan -V] ----> E1+24v

                                  Like this:

                                    So... I have a question, why are the PWM fan ports not protected by a fuse? The only issues I have ever had with this board has been these MOSFETs . I love this board, but this is a serious Debbie Downer...

                                    They are, on version 1.03 and later boards... but sadly fuses blow much more slowly than mosfets do.

                                    On later production we've switched to mosfets with a higher peak current rating, although that's unlikely to help when the output is shorted.

                                      both wires to E1 output if the fan is 24v.
                                      red wire to Vin
                                      black wire to E1-
                                      (E1- is switched to ground when the output is enabled, to use heater4 or any of the other pins on the expansion you'll need an external mosfet to sink more current than the microcontroller can handle)

                                        Just in case it wasn't totally clear, both fan wires will go the the E1 heater connector.

                                        Then in your config.g you would need the follow assuming you're going to use it as Fan0.

                                        Where you have: M950 F0 C"fan0" Q500 you would change it to M950 F0 C"e1heat" Q500

                                        The pin name e1heat comes from this list: https://duet3d.dozuki.com/Wiki/RepRapFirmware_3_overview#Section_Pin_names_for_Duet_2_WiFi_Ethernet

                                          @Phaedrux so I talked with @bearer and he explained this and we tested my wiring across E1vin and mains negative. Fan worked, wiring correct.

                                          1.) Then I hooked up fan negative to E1negative and changed the config line u said above.
                                          Powered up and nothing, using fan control on both DWC and PanelDue are non responsive. my E1 LED is not lighting up. It’s almost like we forgot to associate something? Ideas?

                                          2.) Also, we’re you able to see anything in the config I posted that would suggest why my probe isn’t working and why my homing isn’t working?
                                          3.) Lastly, I’ve tested X,Y,Z movement. Y & Z work as expected. But X only moves in the negative direction (left as it is configured currently) it does not respond when asked to move +x. Does this mean I swapped one of my stepper wire pairs? How do i identify and test that without blowing something up?

                                            Can you post the changes you've made for the fan?

                                            Well your probe settings from your 3.1.1 and 2.03 are very different. One is using probe type P1 and the other P5. What I'm not familiar with probe you list, but if it worked with P5 before it should work with P5 in RRF3. So try to compare and match your settings. The only major difference between RRF2 and RRF3 there is the pin name is now included in the M558.

                                            For your x movement problem, it could be a case of motor rotation direction or incorrect homing switch location.

                                            In your 2.03 config your endstops are configured as low end, but in your 3.1.1 config you have them listed as high end. Which is it?
