@spllg said in my second raspberry has just passed away:
is there any howto to implement this configuration?
pretty much just like the Duet 2 Ethernet setup, take your existing config.g add M552 S1 and move it to the first (or only) fat32 partition along with DWC files etc.
edit: curious as to what would cause the Pi to die, can you add some high res pictures of them, or maybe get them to someone for an "autopsy" of sorts?

there are no visible damages at the rpi. it just stopped working ant won't boot. just the same as the first died rpi. i bought a new rpi connected it to the duet3, inserted the sd-card. the rpi booted and worked fine for about 2 months until it died yesterday.

as i do not know what you mean by 'the DWC files etc', could you provide a reference?
is it possible to connect the duet3 via usb to an rpi? this would enable me to control the duet using wifi via the rpi by means of octoprint.

Are you powering the Pi from the Duet, or independently? Is it possible that you have created a ground loop, either by powering the Pi independently or by connecting something else to the Pi? See https://duet3d.dozuki.com/Wiki/USB_ground_loops.

i am powering the duet 5v from the rpi via usb (internal 5v enable, 5v->sbc and sbc->5v are open) - a configuration which has been working fro ~2 months.
btw.: tried sbc->5v (internal 5v enable open) but this did not work.

Odd, that should have worked.
Does the PSU that powers the Pi use a mains ground pin? If so then you may have a ground loop, and you should power the Pi PSU and the Duet PSU and nothing else except Pi peripherals from the same power distribution block.

the psu that powers the pi dues not use a mains ground pin.

ah, i thought you might have been using previous duets

@spllg I've updated the SD card page, showing how to set up a new SD card for Duet 2 Wifi/Ethernet/Maestro and Duet 3. See: https://duet3d.dozuki.com/Wiki/SD_Card

@droftarts , @bearer thanks - i replaces config.g, .. with my customized versions and connected the duet with a cable to my network -> it prints.
but the issue is not solved. i think if i would install a new rpi it will die after a whils.

@spllg Which Raspberry Pi model? Anything else connected to the Pi? Trying to build up a picture of voltage/current issues, as has been reported in this other thread: https://forum.duet3d.com/topic/15709/undervolts-on-pi

rpi 4b with a display ( https://www.amazon.de/-/en/gp/product/B07YZ3ZVTW/ref=ppx_yo_dt_b_asin_title_o09_s00?ie=UTF8&psc=1 ), nothing else.

@spllg I'd love to get my hands on that pi to figure out why they died, I guess I'm not the only one :). Are those RPI 3B or ?
-
ah rpi4, have you tried powering it trough the 5V on the header and not trough the usb ? (stand alone, not connected to duet)
-
@arhi i have powered the pi from the duet using the header but did not succeed powering the duet from the rpi using the header.

would you like to buy it?
btw: duet 3 running in stand alone mode seems to over extrude quite a bit - at least my extrude settings ceased to work - had to lower it to 80%.

Yes, would be an interesting project to figure out why it died, but it is impossible to get anything in .rs now due to quarantine and police hour. Let's discuss this after this #%$^^&_#@ is over, I'm def. interested.

Do you have both the 5V->SBC and the SBC->5V pins jumpered? They both need to be connected to power the Duet from the SBC.

You guys discussed this a little above, and then moved on. This absolutely will not work (as Dave pointed out). The fact that it does work for @spllg would seem to be the key to whatever is killing these.
As a "cold read" bystander of this thread, I believe you guys should go back and dive into this quite a bit more.

@Danal sorry, i should have written
i am powering the duet 5v from the rpi via usb (internal 5v open, 5v->sbc and sbc->5v are open)
instead of
i am powering the duet 5v from the rpi via usb (internal 5v enable, 5v->sbc and sbc->5v are open)
if it is not possible to 5v-power the duet using the usb port, how can i 5v-power the duet except from the 24v psu by means of internal 5v enable?
-

both? this is contradicting
https://duet3d.dozuki.com/Wiki/Duet_3_Mainboard_6HC_Wiring_Diagramwhich states:
'If you want the SBC to provide 5V to the Duet then remove the jumper from 5V->SBC and from Internal 5v En. Place a jumper on SBC-5V*' (which does not work)
now i'm even more confused.
