      I am trying to connect a Fly RRF36 to my SKR 2 via the dfd board (yes, I know it's recomended to go with the efd board, but I guess I like doing things the hard way 🙂 ). I have installed the jumpers for spi mode, and both jumpers for 120 ohm on the dfd and the toolboard; I replaced

      can.csPin = PA_4
      

      with

      can.csPin = PD_12
      

      in board.txt, which I think is the correct pin, I updated the firmware on the toolboard to the newest version and I can confirm that there is no issue with the wiring (can_L to can_L; can_H to can_H).

      Now, upon power-up, the led on the toolboard flashes rapidly continuously, which indicates that there is no connection established between it and the mainboard, and sending M115 B124 confirms it by giving an error message.

      Is there something that I'm missing?

        @justGuner You can't use a DFD board in a driver socket on the SKR2, it does not have hardware SPI connected to the drivers and the CAN-FD module needs hardware SPI. That's why we recommend the EFD version.

          @gloomyandy I guess that explains it...
          Is there anything stopping me from just connecting it to a breadboard withs some wires to the exp ports?

            @justGuner nope, nothing stopping you doing that

            Owns various duet boards and is the main wiki maintainer for the Teamgloomy LPC/STM32 port of RRF. Assume I'm running whatever the latest beta/stable build is

              @justGuner schematics for the DFD are here https://github.com/Mellow-3D/RRF-spican-modules/tree/main/Hardware

                  @jay_s_uk I have done the following connections according to the schematics:

                  MOSI --- PA_7
                  MISO --- PA_6
                  SCK --- PA_5
                  CS --- PA_4
                  CAN_L --- CAN_L
                  CAN_H --- CAN_H

                  And yet, the led on the rrf keeps on blinking rappidly, and I get "Error in start-up file macro line 24: no CAN buffer available" in console on boot-up.

                  Is there again something else that I'm missing?

                    @justGuner Post the output from M122, M122 P200 and a picture showing how you have the two boards connected.

                            @justGuner That looks ok to me. But your CAN-FD module is not being detected. Things you could try....

                            1. It looks like the dfd module may expect an extra ground pin (pin 8 on the dfd connector, basically the pin at the opposite end to your current VCC connection. I'm not sure if it is needed, but it would normally be connected. Make sure you check the schematic before adding that wire though.
                            2. You could try lowering the SPI frequency used to talk to the DFD. try adding:
                            can.spiFrequencyHz = 10000000
                            

                            To your board.txt file. If that is still not working try:

                            can.spiFrequencyHz = 5000000
                            

                            Other than that I'm out of ideas other than checking the actual wiring and that the pins actually go where they look like they are going.

                              @gloomyandy The other thing you could try is to connect the power for the DFD directly to the 12/24V supply. The SKR2 has a rather wacky power circuit for the drivers that may mean power for the DFD is being delayed, and it could be that the detection code has run before the DFD has settled down.

                                @gloomyandy I have connected the dfd directly to the 24v supply, and immediately began to experience mainboard reset loops upon power-up. I've removed the gnd wire, and now everything powers up as before, but there is stil no can comunication (I did try the above mentioned frequencies).

                                I am reaching the point where it might not be worth it to try and make this work and just buy the EFD and wait 2 weeks.

                                  To add salt to the injury, I thought that maybe I needed to connect the additional int0 and int1 pins. That didn't deliver the expected outcome... (I fried the DFD, hopefully nothing else)

                                  And so, I will post an update on the situation after receiving the EFD in I'm guessing about 2 weeks.

                                  Finally, a little suggestion: you might want to add the reason for why it is recommended to go with the EFD on the teamgloomy website. Not just for the skr2, but for other boards as well.

                                    @justGuner A quick follow up. I've just tested a EFD with an SKR2 and RRF 3.5, seems to be working fine. Jay has also updated the documentation to say that only the EFD will work on those boards for which this is the case.

                                      After recieving the EFD, I can confirm that I have a connection between the skr and the toolboard. However, upon boot, I receive "invalid Z probe index" errors, and an incompatible software warning.

                                      curent software versions:

                                      I also tried with rc.3; same outcome

                                        @justGuner You need to use the same version for all of the components, your screen shot shows a mixture of rc.1 and rc.2. If you think you have the correct versions installed run M122 and M122 B124 and post the output here.

                                        M574 Z1 S2 ; configure Z-probe endstop for low end on Z

                                        You also have the above in your config. See the following notes for option S2:

                                        The S2 option of M574 is intended for use only when axes other than Z are using the Z probe for homing. The only printers known that do this using Duet electronics are the RepRapPro Ormerod, Huxley Duo, and Mendel Tricolour machines. When using the Z probe to home Z, M574 Z has no bearing on the probe setup or usage. A Z probe and a Z endstop can both be configured at the same time. G30 calling the probe setup with M558, and G1 H1 Z moves calling the endstop configured with M574 Z.

                                        That may be generating the probe error as at that point in the config, you have not defined a probe. Either way you almost certainly do not need that setting and should probably delete it.

                                          @gloomyandy I updated every component to rc.3 and now everything works as it should. Originally I thought that the latest version for the rrf36 was rc.1; apparently I just wasn't patient enough for it to update over usb and it would boot up with the old one.

                                          Thanks for the help.

                                            @justGuner Once a version of RRF is installed on the toolboard you should be able to update via CAN-FD no need to do it via USB.
