Duet3/pi DCS is unavailable after wiring 24V

fractalengineer

@bearer Ok;

I just flashed to RRF 3.01 RC6 with the previously updated DSF 1.3.1 ; still blinking, still can't connect to DWC

Tried RRF 3.0 with 1.2.4 earlier before original post; wasn't working either.

Nuking the card now; let's see if it does anything

Not 100% sure the blinking is a problem though; the unable to connect bit on the other hand is.

Make sure the board shows up with the Duet3 vid/pid and responds to M115 and/or M122.

Plus any combination of reccomended versions as pr the link where dc42 and chrishamm list their reccomendation and then see if one of them have anything to add I guess. I'm off for a bit.

@bearer Thank you for all the help; I agree the flashing led is not an issue; just a symptom I want to mention as it's supposed to be shut in normal operation.

Nevertheless, just completed the flashing and setup on fresh install, and still the same issue.

Here's the current status:

It appears that the Duet can communicate with my computer over serial USB, but can't communicate with the Pi for some reason.

See

Apr 12 13:32:45 duet3 DuetControlServer[1405]: [error] Duet is not available

Any ideas how to take it from there? Thanks everyone

it leaves the spi connection over the ribbon cable, or problems with the DSF package on the pi. Double check the ribbon cable, although i don't think it would work if it was off by a row/column.

while waiting I suppose you could try populating the SD card with /sys/config.g + DWC in /www and run it without the Pi to see if it helps determine if there are any problems with the board.

fractalengineer

@bearer sure of course I'll try anything to make it work

The ribbon cable looks mint and was very clearly connected properly

I just replaced the config.g file with the machine one and inserted the SD card in the boar but how did you mean to connect to it?

The diag led is still blinking

but how did you mean to connect to it?

when the Duet3 has an SD card with a config.g file it will for all intents function as a Duet 2 Ethernet, so having DuetWebControl on the SD card and using the Ethernet connection it should function without DSF on the Pi. No change needed to the firmware, it will detect the config file on the SD card in the SD card socket on the Duet 3.

fractalengineer

@bearer I see; I never had a Duet 2 this is my first board; thank you for clarifying.

Well I then followed the Duet 2 Ethernet Dozuki and enable networking; this is what I get now;

Still can't connect, led still blinking

Different error message though

The diag led is still blinking

That is what it is supposed to do on a Duet 3 in normal operation. It shows that the Duet is alive and running RRF. When expansion boards and/or tool boards are connected to the Duet 3 via CAN bus, the LEDs on those boards blink in sync with the one on the Duet 3 to indicate that time synchronisation has been established between them.

There have been problems with the 3.01-RC6 and DSF 1.3.x combination, and new releases will be available soon. Until they are available, it's best to run either RRF 3.01-RC6 in standalone mode (i.e. without the Pi), or RRF 3.01-RC5 with DSF 1.2.5 (and DWC 2.0.7 in either case).

A Former User

Hmm, if you're using a compatible version of DWC that should rule out problems with anything DSF and Pi related.

Looking at the https://github.com/dc42/RepRapFirmware/releases/tag/3.0 page it says DuetWebControl 2.0.4. Or go with 3.01-RC6 + DWV 2.0.7 as suggested by dc42.

fractalengineer

@dc42 thanks for the response; ok so the blinking led is just a status light. I didn't remember it flashing before but now I know.

Ok so I started by flashing to 3.01-RC6 in standalone; still no chooch

DWC is still in 2.0.7 stable from the last status update.

what would you advise to do next? There's probably nothing that will come from trying to run it off the Pi if it doesn't even run by itself?

A Former User

I'd look at the network traffic next; using wireshark to capture the packets to/from your computer.

And yeah, whatever the problem is, it will be the board itself or something networking related so might as well keep it simple and leave the Pi out of it for now. However if the issue is networking its strange DCS said DuetControlServer[4530]: [error] Duet is not available when on the Pi.

fractalengineer

@bearer good day,

Man that's getting very technical I've never worked with such software.

Is this the only way to troubleshoot moving forward? @dc42

fractalengineer

@bearer ok I managed to get wireshark to run and show interfaces; needed some troubleshooting too to work on Win10

It's capturing now; what should we be looking for?

Thanks

upload the file and I can take a look if I see anything to suggest where the problem lies?

(Edit: Start the capture, open a private browsing window or incognito window or whatever your browser calls it, try to open the Duet web page and then stop the capture. Don't have anything you'd consider sensitive going on at the same time)

fractalengineer

@bearer Thank you; sure here's a capture file; I started recording right before sending the M552 S1 command so there shouldn't be anything missing

I then attempted connecting to the DWC until the network error message showed up

https://we.tl/t-gPUhISpL9Z

A Former User

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:)

fractalengineer

@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

A Former User

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 == 192.186.0.11 and hit enter (after starting the capture), you can verify you're getting the right stuff.

A Former User

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 print on the computer to see how the networking is configures?

fractalengineer

@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 because M552 S1 P0.0.0.0 doesn'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 print doesn't show any 192.168.0.11

So it looks like all I can do is half access DWC on my browser, but it doesn't show any traffic?
