    It has a 5V 3A regulator on it for the raspberry

    have you considered the load on the 1A fuse for the fans when you're taking a good chunk out for the 5v buck?

    Yes you are right. I thought the always on Fan are directly connected to VIN

      Now you are right. I thought the always on Fan are directly connected to VIN

      might not be a problem, you should have 3-400mA left for fans driven by Vin, I was just trying to make sure you'd take it into account.

      edit: I've used some of these type of things to tap the fuse for putting on a step down for fans (mini - not low profile, ATM or ATP fuse)

          i got the same, but as long as you can use Bossa to do any programming after the inital flashing you don't need the IAP binary

            So tested my PCB today. Its working fine. 🙂 So I just miss the IAP that I can flash the duet trough DWC.

              With SBC there is no SD card needed in the duet right?

                it explicitly needs to not have a SD card with a config.g on it. (at least for now (RRF3.2), been some discussion on changing that)

                  I got it 😄 I removed the SD Card now my config is working

                    @Dougal1957 DSF is absolutely the same. It does neither know nor care if it's a D3 or a D2 on the other end.

                    not 100% accurate .. if one were to suffer from pendanticitis(?) .. upon first connection it says "Welcome to your new Duet 3" .

                    ...good thing i don't 😎

                      @bearer Have you found a solution building DuetIAP?

                      maybe @wilriker can help us?

                        sort of; wait for 3.2 release candidates as I don't really need it.

                        I just send M997 P"ERASE" M999 P"ERASE" and upload firmware with bossac from the pi.

                          It's actually M999 P"ERASE". 😉

                          Anyway, I remember I had that compiler error as well. I just don't remember what I did to fix that. I can most likely only check on Monday in more detail. Meanwhile I try to upload my IAP binary to Dropbox and then share here.

                          EDIT: find the IAP here: https://www.dropbox.com/s/rkcb3chqk878nkm/Duet2_SBCiap_2SBC.bin?dl=0

                              That's a victim of recent refactorings. Currently looking into how to fix it best.

                                After some testing with the sbc configuration, I have problems with homing my tool changer.

                                I have configured 3 additional axes. However I do a home all, all axes getting homes besides the last "W" axes and the printer hangs forever. After some time the printer then resets itself automatically.

                                If I home all axes separately it is working fine so far. Also the whole configuration what working fine before.

                                I also made a short video:
                                https://photos.app.goo.gl/1YnQmdPAnkXtDG2X8

                                Is there a possibility to grab logs why it is crashing?

                                  So building IAP is fixed on dev-wilriker branch in DuetIAP repo.

                                  @smoki3 First of all you can ignore the error at the end of your log excerpt. That will be fixed in the next DSF version and has nothing to do with resets. The Bad checksum statements on the other hand really are the cause of the reboot.

                                  Can you please post again which resistors you use on which line and also both your DCS config.json as well as (if you use an actual Raspberry Pi) it's /boot/config.txt.

                                    I use 360 Ohms in MISO MOSI and SPCK. No additional resistors on NPSC0 and EDR because the duet 2 already have 2.2kOhms on board.

                                    I am using a RPI 3:

                                    Boot config:

                                    GNU nano 3.2 /boot/config.txt
                                    # For more options and information see
                                    # http://rpf.io/configtxt
                                    # Some settings may impact device functionality. See link above for details
                                    # uncomment if you get no picture on HDMI for a default "safe" mode
                                    #hdmi_safe=1
                                    # uncomment this if your display has a black border of unused pixels visible
                                    # and your display can output without overscan
                                    #disable_overscan=1
                                    # uncomment the following to adjust overscan. Use positive numbers if console
                                    # goes off screen, and negative if there is too much border
                                    #overscan_left=16
                                    #overscan_right=16

                                    # overscan.

                                    # uncomment if hdmi display is not detected and composite is being output

                                    # uncomment to force a specific HDMI mode (this will force VGA)

                                          @smoki3 The second file http.json is for the DWS (Duet Web Server) not relevant for the problem here.

                                          This is a shot in the dark but please try adding

                                          # Fix core frequency to have constant SPI clock speed
                                          core_freq=250
                                          core_freq_min=250

                                          to your /boot/config.txt and reboot the RPi. It might be that Duet 2 does not like RPi's default SPI frequency shenanigans (neither do I 😂 )
