Duet3/pi DCS is unavailable after wiring 24V
-
looks like you maybe captured the wrong network interface? admittedly instructions were a bit lackluster.
i'll be in later, for now its blue skies and a "strange bright light" outside:)
-
@bearer I don't think so? This is the only interface that gives no pulse until I turn on the networking service on the Duet
-
I'm not seeing any traffic to suggest there is a Duet on the network; nor any traffic with the IP shown in the serial output.
if you enter a display filter of
ip.addr == 192.186.0.11and hit enter (after starting the capture), you can verify you're getting the right stuff.
-
I assumed the network was okay as you've shown the browser loading the DWC page; but you're setting a static IP and have both wired and wireless network.
Can you elaborate a little on how its all connected, and maybe run
route printon the computer to see how the networking is configures? -
@bearer well I don't know what to say;
-The duet is wired to my laptop using an ethernet cable
-Laptop is connected to wifi router
-I set M552 with a static address becauseM552 S1 P0.0.0.0doesn't return a dynamic IP; nothing shows on my IP scanner either
-I chose 192.168.0.11 because that's the one Octoprint was always dynamically assigned to on this rpi
-Even with the static IP, every second time I enter it in the browser I get the DWC loading screen, or a timeout
-The wireshark filter doesn't return any match
-route printdoesn't show any 192.168.0.11So it looks like all I can do is half access DWC on my browser, but it doesn't show any traffic?
-
@bearer here; I can see the DWC loading on my browser, but see the route print:

(And this is why we say "If you don't like the weather in Bergen wait 5 minutes" ... its snowing now)
Aaanyways, I suspected something like that after briefly looking at the capture.
The computer doesn't have any network configured for the wired ethernet interface, so you'd have to set a static IP on the computer as well (and on a different network than 192.168.0.11) OR see if you can connect the ethernet cable from the Duet to your wifi router.
As to why you can load the front page I can only put down to caching somehow, which I hoped to avoid by using a private or incognito browser window.
So run the cable to the router or set static IPs for both the duet and the computer, choose something like 192.168.1.11 and 192.168.1.12 for the two (note 0 changed to a 1)
-
@bearer hey you're from norway
I visited Oslo once for a weekend while I lived in Sweden; I know what you mean lolWell chief at last we made some progress
Connected the duet to the router, dynamic IP assignment worked for the first time, and DWC is FINALLY loading properly, at least locally:
How would I move forward making sure it works when running it through the RPi now?

Not sure, even if the rPi were to suffer similar networking issues it still didn't find the Duet on the SPI bus so we're not gonna make much more progress on that front I suspect.
I'd proceed to getting things set up and running as is while the Duet people are working on getting RRF 3.01 to a stable release. The config you make for the Duet in stand alone mode should transfer to using with a pi afaik.
-
@bearer but it worked fine over the pi before; I can't leave the machine wired to the router, I don't need the latest 3.01 either
Is there a way to make it work with the pi with RRF 3.0?
-
It should have worked with the clean Pi image and RRF3.0 afaik.
I think I missed that it previously worked; what happened when it stopped working?
You can go back to the pi and we can chase down the network if thats the problem, but I wouldn't hold my breath.
If you don't make any progress on using the Pi as intended, we can turn it into a wifi bridge so you can get on with things without having the cable running to the router. (Or you could set a static ip for your computer - possibly even use internet sharing if your windows has that feature)
-
@bearer thanks, I'd be keen to troubleshoot the network issue on the pi first.
I don't think I did anything crazy since it last worked; I had to plug/unplug the ribbon a few times as I was still using that pi for octoprint on another printer while waiting for the final parts of that new printer to show up
I never unplugged the ribbon while powered, and only noticed the DWC connection issue when I first powered the Duet through VIN

I don't think the pi issue is network related, but if you capture the traffic with wireshark I'll take a look.
do make sure to not try to access the pi 5 minutes before starting the capture (should ensure wireshark picks up the ARP traffic, or run
arp -d *in an elevated command prompt)If you still find
Apr 12 15:58:56 duet3 DuetControlServer[4530]: [error] Duet is not available
when running
journalctl -u duetcontrolserver -e(don't think you should needsudofor that, but stick sudo in front if it doesn't work) then its not going to work no matter what we do to the network. -

so it never worked through VIN?
-
@bearer Ok I plugged the pi back, changed sd card and replace the config file, as well as flash the board back to rrf3.0
- Still not working
- I don't know how to run that arp command; here's what I get:
pi@duet3:~ $ arp -d * Desktop: Unknown host pi@duet3:~ $ sudo arp -d * Desktop: Unknown host pi@duet3:~ $-
Journal command still reports unavailable Duet
-
Either way here's the capture; pi's IP is 192.168.0.11, I start by logging in SSH, then try to launch DWC in browser, first normal then private session. That's what's in it: https://we.tl/t-2T4XTTek8p
-
A friend of mine will let me borrow his Pi 4 tomorrow to narrow down whether the issue comes from the duet or the pi
-
It powers up through VIN but behaves just like powered through USB; DCS unavailable
Thank you

my bad, instructions uncear. that would be a windows command, as we'd want to clear the arp cache on the host running wireshark. (but its moot point, no doubt about which host the pi is, and seems to be no firewall issue)

thats a problem between the pi and the Duet over the spi bus. can you do
ls -l /dev/spi*on the pi?@fractalengineer said in Duet3/pi flashing Diag LED after wiring 24V DCS is unavailable:

i might be paranoid, but i'd get Peter Griffins volcano insurance just in case.
I'll have a (closer) look at the wireshark log a bit later, but when DCS reports the Duet is unavailable then thats where the problem is.

thanks for clarifying; I can try the arp command again if that capture doesn't work
thats a problem between the pi and the Duet over the spi bus. can you do ls -l /dev/spi* on the pi?
Sure here's what I get; I did remember very clearly enabling SPI during the setup process
pi@duet3:~ $ ls -l /dev/spi* crw-rw---- 1 root spi 153, 0 Apr 12 15:45 /dev/spidev0.0 crw-rw---- 1 root spi 153, 1 Apr 12 15:45 /dev/spidev0.1i might be paranoid, but i'd get Peter Griffins volcano insurance just in case.
Lol what do you mean?
And thank you again for all the support; looking forward to hear what you see in that capture
Cheers

No need, and capture looks about as expected, computer connects to Pi they switch to websockets and everyone is happy as far as I can tell.
Problem likely lies in that DuetWebControl which runs on the pi and cannot connect to DuetControlServer because its cannot find the Duet on the SPI bus and doesn't start.

You're not using the image from here? https://duet3d.dozuki.com/Wiki/SBC_Setup_for_Duet_3 (it should have SPI and other stuff ready to go)
In any case I don't think I can pinpoint problems any further than its beetween DCS and the Duet3 board. Maybe dropping the SPI speed could be worth a try, if no one beats me to it I'll see if I can't post some instructions later.

Seems to be the same as the one linked in the "get started" guide, so I'd say yes
I have no clue how to do the spi speed thing so I'll be on the lookup; thanks

neither did I..
and a few quick searches didn't bear fruits, however https://forum.duet3d.com/post/109561
the config.json file would be
/opt/dsf/conf/config.json
