      @dc42 thanks for your reply. i cloned from https://github.com/Kriechi/Cura-DuetRRFPlugin/ . this seems to work fine

      it seems to have the ability to crash cura - staying with saving gcode to file and downloading this file to rpi.

        please consider filing a bug report to the github page for the plugin; it might just help get it fixed by the developers

          While I'm sure there are plenty of reasons to carefully consider purchsing S3D

          like any sw, one should ge informed, I "trusted someone" and didn't, was too late when I figured out who I'm dealing with 😞 so I say to everyone just check the forum, if you feel confident about that company and want to be part of that community (where forum is heavily censured, where promisses are never held, where everything is presented as shiny big and huge while... also one important thing I learned from using s3d is to always, always check who I'm dealing with on glassdoor ).
          It is still a great slicer none the less!

          getting prints to a(ny) Duet isn't one - I have used the curl commands with a Duet2

          For RRF3 on Duet2 I use

          rrf3.bat "[output_filepath]" 
          

          where rrf3.bat is

          @echo off
          
          for %%a in (%1) do (
              set filepath=%%~dpa
              set filename=%%~na
              set extension=%%~xa
          )   
          set if=%filepath%%filename%%extension%
          
          G:\bin\curl-7.50.3-win64-mingw\bin\curl.exe -G --data-urlencode "gcode=M30\"%filename%%extension%\"" http://ender5.local.lan/rr_gcode
          G:\bin\curl-7.50.3-win64-mingw\bin\curl.exe  --data-binary "@%if%" "http://ender5.local.lan/rr_upload?name=gcodes/%filename%%extension%"
          
          

          works like a charm except if file name comes with space then it fails

          something similar can for sure be made to work with RRF3+SBC, if you can upload trough web interface, you can send it using CURL ... you put this in the script tab in s3d and forget... it works great

            gtj0 posted the POST endpoint for running gcode and i think the PUT endpoint i added to that should to the trick (i incorrectly assumed it'd be a bigger deal as it wasn't already supported and turned to ssh/scp that would achieve the same thing)

              the 3rd rpi has just passed away.

              the printer was switched off for 1 week. after switchin it on it started up fine and i started to print but after ~5minutes it stopped, the http-interface did not respond any more. a reboot of the rpi failed (the green led flashed a few times and was switched off).

              i'm tired messig around with rpis (i've got two others and both are up and running for years now).

                I am somewhat puzzled at the point of this post. In an effort to understand the relevance, I need to enquire:

                Do you in some way feel that the duet-3 is responsible for the demise of the Rpi?

                  version of them? and post failure which leds do what, is it the same for all of them? (edit: and how are they powered and conneted to the duet?)

                    @bearer Raspberry Pi 4 Modell B; 4 GB, ARM-Cortex-A72 4 x, 1,50 GHz, 4 GB RAM, WLAN-ac, Bluetooth 5, LAN, 4 x USB, 2 x Micro-HDMI

                    when powering up the red led is switched on. than the green led flashes a few times and nothing more happens.

                    when i put the sd-card into another rpi it boots fine.

                    yes, all the rpis passed away the same way - print stopped, rpi does not respond not even to a ping request and does no longer boot up.

                    the rpi is powered from an original rpi psu, the duet is 5v powered via the ribbon cable (5v->sbc and sbc->5v both closed as instructed by dc42).

                      @CaLviNx as it is the 3rd rpi demised in conjunction with my duet3 6hc) while 2 other rpis (not connected to a duet board) live for years now, i feel the duet is somewhat responsible for the deaths.

                        so in short the Pi and the Duet are always powered on at the same time? that was mostly what I was after.

                        understandably frustrating as those things aren't exactly cheap; is there anything else connected to the Pi and have you tried alternative boot medias to the SD card post failure? If you're not interested in spending time and effort on postmortem analysis thats understandable.

                          the rpi does not boot from another sd-card (which works fine in another rpi) and the rpi boots fine from the sd-card of the dead rpi.

                          there's an rpi display and an rpi camera connected to the rpi - unconnecting these devices and the duet ribbon cable does not change anything.

                            i was thinking USB or PXE or something not an sd-card?

                              @bearer preparing a memorystick using dd. hopefully the rpi is able to boot from usb device.

                                Horse Manure.....

                                As long as the duet is not sending an over-voltage to the Rpi (and you have said yourself the Duet is not the one sending the Rpi voltage) then I dont see how it is possible for the duet to kill the Rpi.

                                The logic is flawed i'm afraid.

                                  @CaLviNx what do you mean "the logic is flawed"? please explain!

                                  edit: the rpi has been working fine fine in conjunction with the duet for more than 4 months.

                                    @bearer no, the rpi does not boot from usb-stick but i do not know if it would have done before. the only visible difference is that the green led stays on.

                                      i think calvinx is hinting at causation without correlation btw

                                      anyways, no the pi4 needs an update to the boot eeprom to boot from anything other than the sd card, not sure if you can accomplish that easily without being able to boot from the sd card. maybe trying to recover the boot eeprom is worth a try, but if you say the green led does blink at boot then it sounds like it should be ok (it'd still be interesting to see if it was able to boot from another medium, however that requires changing or interfacing directly to the spi eeprom i think)

                                        @bearer tried to follow the recovery section in https://www.raspberrypi.org/downloads/ but currently i do not have an empty sd-card. going to order one but i think unless the rpi can boot and operate from usb this will not solve my problem.

                                        reconfigured my printer to operate without rpi - maybe this is an persistent solution although i'm going to lose some workaround.

                                        still wondering what might be the reason for 3 dead rpis.

                                          @spllg you could image a card that is not empty, format it, put the recovery stuff on it, and restore the original content after attempting the recovery as an alternative to ordering a new card.

                                          the pi4 can boot from usb, but weather or not you're able to make the seemingly damaged pi's boot from usb is another matter all together, its just a long shot to determine if the issue is the sd interface or something else.

                                          does the screen show anything when you attempt to boot the dead pi, and is there any difference with or without an sd card?

                                            I can think of a couple of situations in which the Duet cold send over-voltage to the Pi:

                                            1. If you are powering a servo for the Duet +5V supply as well as the Pi. Servos inject current into the +5V rail when they decelerate. I've seen Vcc on a Duet 2 rise temporarily to 8V when driving a servo.

                                            2. If you have a static discharge to +5V, which would typically be from an un-grounded stepper motor body or from the hot end.
