      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?

      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.

            @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 
            
            

            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.

            This document also has the best overview of the changes.

              @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

                          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?

                                    @Phaedrux i tested the TR8 mosfet for E1 and i only get 4.5v out of it. my guess it was also blown. @bearer is helping setup external mosfets to control my fans via the 50pin expansion header. I think i am set there.

                                    I played with the probe settings after noticing the same things u just mentioned.
                                    I tried both probe types 1 & 5, I tried inverting the signal with a "!" in front of the C var, i tried changing the end stops for XYZ from 0, 1, 2.
                                    Nothing works, the only thing i notice is the probe reading is 1000 for P1 and 983 for P5 when no metal is present (probe light off). When i put a metal object under it, the reading drops to ~20.
                                    It acts this way for every permutation of the above code changes.
                                    I know this, my optical sensors were wired in RRF2 to the same pin as they are now, just ~1m extra wire in between. These sensors have to run 5v+, not 3.3v per the way the OEM wired them. But if i download the sensor Mfgr's data sheet it says, it needs 12-24v in. GL_8H Sidewinder X1 Endstops Data Sheet.pdf

                                    Do you suppose the extra length of wire causes enough resistance that the 5v that previously worked, now is not sufficient? If so, i could re-wire to pull off the main's power in... just a lot of extra work that i may not need to do...

                                      @jallen810 said in Possible PWM port issue & RRF3 Question:

                                      When i put a metal object under it, the reading drops to ~20.

                                      I think that would be the inversion, so you'd need the ! in the pin name.

                                      You might also need the pullup resistor enabled by adding a ^ to the pin name

                                        @Phaedrux okay I will try that, what exactly is the application for this pull up resistor? Could it be the reason my endstops are acting funny?
                                        It almost acts like the machine thinks it’s homes as soon as I push the home button... very weird.

                                        My homex,y,z and all fills are updated from S to H.. so that looks fine... any other ideas other than I just need to try running 24v of power to them?

                                          @jallen810 A pull-up (or pull-down) resistor is a resistor used to ensure a known state for a signal. A switch should either send a 3.3V, or be connected to GND (0V), but some switches 'float' and give a partial voltage, which can lead to unexpected triggering. A pull up resistor will make sure that voltage is 3.3V. However, I don't think this is your issue.

                                          Your probe:
                                          Old RRF2 config: M558 P5 H5 F600 A1 I1 The 'I1' means the probe is inverted. A1 is the number of times the probe will probe each point (1 is default). No travel speed 'T' set.
                                          New RRF3 config: M558 P1 C"zprobe.in" H5 F600 T6000 Wrong probe type, not inverted. Try:

                                          M558 P5 C"!zprobe.in" H5 F600 T6000
                                          

                                          See https://duet3d.dozuki.com/Wiki/Gcode?revisionid=HEAD#Section_M558_Set_Z_probe_type for details.

                                          Your endstops:
                                          Old RRF2 config: M574 X1 Y1 S0 endstops on low end, S0 means active low
                                          New RRF3 config: M574 X2 S1 P"xstop" and M574 Y2 S1 P"ystop"
                                          Both set at wrong end (X2 and Y2 should be X1 and Y1, unless you've changed the position). S1 is fine (says it's a microswitch), but needs to be inverted. Try:

                                          M574 X1 S1 P"!xstop"
                                          M574 Y1 S1 P"!ystop"

                                            Thank you all for your help with this upgrade to RRF3, I did finally get everything working properly again! I am running my first print now! Woot woot!

                                            One last question to you @droftarts, I figured out that I had to invert my endstop signals ~2hr before your comment but I had to do the following:

                                            CONFIG.g

                                            ;----Endstops--------------------------------------------------------------------------------------------------------------------------------------------------------------------------
                                            M574 X1 S1 P"!xstop"                                       ; configure active-low endstop for low end on X via pin xstop
                                            M574 Y1 S1 P"!ystop"                                       ; configure active-low endstop for low end on Y via pin ystop
                                            M574 Z1 S2                                                 ; configure Z-probe endstop for low end on Z

                                            G1 H1 Y-340 F360  ; move slowly to Y axis endstop once more (second pass)
                                            G1 H2 Z-5 F6000  ; lower Z again
                                            G90              ; absolute positioning
                                            

                                            Question is: Why did I have to switch my "home" coordinate for both X&Y from 305/340 to -305/-340 when I switched to RRF?
