Single Setup for Duet 3

Dougal1957

Is there an Image available for a PI4 that we can download and burn? Or relatively simple build instructions for those that are Linux illiterate

@Dougal1957 the same image should work on both

Further to my previous post, new firmware for Duet 3 is now available at https://github.com/dc42/RepRapFirmware/releases/tag/3.0beta10.

@4lathe So I just setup my rpi4 in advance of receiving my duet 3 this week. No errors were thrown using the oem duzuki instructions. However when I http://127.0.0.1 on the pi I get
This page isn't working
127.0.0.1 is currently unable to handle this request.
Http error 500

When I run the journal I can see some errors but I have no idea what to do with any of it.
Any help much appreciated!

Maybe post some of the errors?

@4lathe error shown in journal was
Cannot assign requested address /var/run/duet.sock

4lathe

@4lathe that came right after
Request starting HTTP/1.1 GET http://127.0.0.1/

@4lathe actually others are just a repetition of that error.

i think that would suggest you either don't have permissions, or its already in use. did you use sudo to run as root?

4lathe

@bearer I was logged in as pi when I executed all the dozuki instructions. Many of those use sudo. I did have to add sudo in front of one of the commands though.

@4lathe DSF wont serve anything is the Duet is not connected.

4lathe

@T3P3Tony ahhhhh. What was that error? Any good way to test that the web server is running?

Ah, as tony says, thats not gonna work. everything depends on DuetControlServer, and it won't start without the Duet3 connected.

4lathe

@bearer ok so just leave it for now?

yeah, might as well, you won't be able to verify the software anyways.

Although I'm puzzled by the fact that you say you get a HTTP 500 error if the Duet3 isn't connected, which is why I glossed over that bit initially.

4lathe

@bearer no idea.

The DuetWebServer will start but it communicates with the DuetControlServer via that /var/run/duet.sock socket which is created by the DuetControlServer and that won't even start if it doesn't get a response from the Duet3 via the SPI bus. So when you access the web server, it responds with a 500 because it can't connect to that socket.

@gtj0 ah, must have changed the behavior at some point then, previously it would terminate right away if started manually without DuetControlServer; and the systemd service won't even start.

Anyways, moot point, gotta wait for the board in any case.

@bearer thx much for the explanation.
