Cannot Connect to Duet 3 Web Control

Phaedrux · 7 Jul 2021, 17:29

If you connect ethernet between your computer and Duet you must configure a static IP address on both. If you're connecting to the router, the router can issue a DHCP IP address to both as long as the Duet is configured to request one.

You can retrieve your config.g from the SD card in the Duet by putting the SD card in your PC and looking for it in the /sys/ folder.

@phaedrux My config.g file has been untouched and when I had access to the web control, it was extremely empty.

@phaedrux When I type in M552, it reports "Ethernet is enabled, configured IP address: 192.168.2.2, actual IP address: 0.0.0.0 <LF>ok<LF>". I set my computer IP address to 192.168.2.1. Also when I type in M552 S0 and then M552 S1 P192.168.2.2 (to set the IP address), I only get ok <LF> as a response. Not sure if this is normal.

@frank-0
Bolded portions are taken off the guide/documentation linked in my original post (Step 10).

DHCP: Most home routers are setup to assign IP addresses by DHCP. Send M552 S0 to disable networking, then M552 S1 P0.0.0.0 to enable networking and have your router assign an IP address.

When I type in M552 S1 P0.0.0.0, I simply get ok<LF> as a response. It doesn't reply with Network running and the IP address the duet is using. Typing in M552 after to check, it just says "Ethernet is enabled, configured IP address: 0.0.0.0, actual IP address: 0.0.0.0 <LF>ok<LF>".

Fixed Address: You can set the Duet to use a fixed IP address. Note that if you use a fixed address, care should be taken that it does not conflict with other devices on the network. Send M552 S0 to disable networking, then M552 S1 Px.x.x.x to enable networking, where "x.x.x.x" is the IP address you want to use, eg 192.168.1.15.

When I type M552 S1 P192.168.2.2, I get the same response of ok<LF>. Then when I type M552, I get "Ethernet is enabled, configured IP address: 192.168.2.2, actual IP address: 0.0.0.0 <LF>ok<LF>".

In both cases, after 10-30 seconds the board should reply with Network running and the IP address the Duet is using. Send M552 to check the settings.

-This does not happen for me. I never get the network running response.

Do you see the link light on the ethernet port on the Duet light up at all?

Frank 0 · 7 Jul 2021, 18:16

@phaedrux Where is that? Right under the ethernet port? I do not see a light on.

Phaedrux · 7 Jul 2021, 18:23

Do you have the ethernet cable connected to your router or your computer?

Can you please post your config.g from the SD card? I'd like to see what it's set to do at startup.

Can you also send M122 in the terminal and copy and paste the results?

Frank 0 · 7 Jul 2021, 18:34

@phaedrux Right now I have it connected to my computer and I am trying to configure/set an IP address. I also set an IP address on my computer. I also tried connecting it to the router, but that did not work either.

I can't see anything in your photo. What am I looking at?

Please configure YAT to use the correct line break format so we can see the fulll report.

@phaedrux I realized the image was impossible to read. Sorry. It was meant to be the config.g file.

.

When I was on the web control, I changed the 0.0.0.0 to 192.168.2.1

Frank 0 · 7 Jul 2021, 18:37

@phaedrux My version of YAT does not have these settings. It looks different.

Frank 0 · 7 Jul 2021, 18:41

@frank-0 Is the "ETHERNET(blocked,211)" section of this text a concern?

Phaedrux · 7 Jul 2021, 20:04

Are you using a single board computer like a raspberry Pi with your duet3 right now?

Frank 0 · 7 Jul 2021, 20:25

@phaedrux No I am not. I realized the error with the network commands was because the SD card got loose. I am trying to get a wired network connection (ethernet) and access the web control page.

https://duet3d.dozuki.com/Wiki/Setting_up_networking_on_Duet I have read and looked at this page as well.

Phaedrux · 7 Jul 2021, 21:33

So with the SD card back in place are you having better luck?

Frank 0 · 8 Jul 2021, 17:06

@phaedrux Better, but still not completely working. Is it possible to connect via just USB instead of using the ethernet/networking?

Phaedrux · 8 Jul 2021, 18:22

How does it behave now? Are you able to connect to the web interface or not?

Does the SD card have the correct files in the /www folder?

You can stream gcode over USB from a sender program like octoprint or simplify3d or pronterface, but you lose a lot of features including speed and quality.

Frank 0 · 12 Jul 2021, 19:29

@phaedrux When I try to set up the networking, I get this on YAT: . Visiting this address on a browser does not work. I just want to connect to the Web Control

fcwilt · 12 Jul 2021, 19:48

@frank-0

You have to have on the SD card a basic config.g and the files for the web interface.

Do you have those on the SD card?

Visiting this address on a browser does not work.

What do you actually see in the browser when you try to go to that address?

Are you able to ping that address from your computer?

What IP address does your computer have?

This will help us confirm if you're able to communicate with the Duet over the network.

Can you show us a screenshot of the contents of your SD card?

At minimum it should have a folder structure similar to what is shown here: https://duet3d.dozuki.com/Wiki/SD_Card#Section_Creating_the_file_structure

If the /www folder is missing or empty, you won't be able to connect to the web control even if the network connection is good. If it's missing or empty, you can replace the files using this zip file.

https://github.com/Duet3D/RepRapFirmware/releases/download/3.2.2/DuetWebControl-SD.zip

Extract the contents of that zip file into the /www folder.
