Duet 2 WiFi - Web Control Connection Issues

tec_bamm · 7 Sept 2018, 09:17

Hi guys! New to the forum.

Setting up our large scale 3D printer, using the DuetWiFi with the Duex5 extension. We had some trouble connecting it to our office network (WiFi connects, but IP address that's stated on YAT and console doesn't exist on our network), and I tried to connect it using M587.

To remove and add networks, I do M588 S"" and M589 S"", then I re-enter the network IDs through M587 S"XXXX" P"XXXX" Ixxxx Jxxxx Kxxxx. I reset the WiFi module M552 S0 and S1.

On the other hand, we connected it to a tethered phone, through the same means, which worked, but the Duet Web through my local 192.168.x.xx IP disconnects a few seconds after it's been connected to the board.
On the LCD screen we have, Console is saying that we are experiencing a "WiFi reported error: incomplete write".

Can anyone please advise on what to do, since it seems like we're going around in circles with our current process.

Are you sure that the IP address you are specifying in the M587 command is available on your office network? It needs to be on the same subnet, and not already in use. It's usually better not to specify an IP address and let your router allocate one using DHCP.
Is it a small office WiFi network, or a corporate network? Some corporate networks require a logon procedure that is not supported by the Fuet WiFi.
Regarding the "incomplete write" error, please connect YAT and send M122, then report the main firmware version and WiFi firmware version from the report.

1: Yes. I know all of the used IP addresses on the network, and our Duet is connecting to an unused IP. It was initially done, not specifying an IP address through DHCP, but it still doesn't appear on our office router. Since it never managed to connect to it through automatic means, I entered manual numbers, which still doesn't appear to run the Web Server.

2: It's a small office WiFi network. The router we're connecting it to doesn't require the corporate login.

3: I shall report to you what M122 states. I am hoping that it's both at 1.21. I'll reply with the M122 results in a few minutes.

There are only two problems right now though:
1: It cannot connect to our office WiFi
2: It connects to my tethered phone, although it drops after 30 seconds, after successfully connecting, so config.g is inaccessible from the timeframe that it's active.

@dc42 Do you perhaps know how to split the lines on YAT? M122 only separates them with <LF> but keeps on going the single line. It now says that I've run out of bytes.

I just separated the <LF>s manually so you can see it more clearly, but that's all that the lines give me. I notice it saying DuetWiFi 1.02, but I really don't recall even touching that version on the downloads list. Does that mean that I've forgotten a file and it didn't install when I did M997 S0:1:2?

In the YAT text settings, change the line ending to LF only.

The WiFi firmware version comes later in the report.

Ok. I shall find out what the full M122 says. Thank you for the reply!

Thanks. Your firmware is up to date with latest stable release. Please upload and re-install DuetWiFiServer.bin from the 2.01 release area (https://github.com/dc42/RepRapFirmware/releases/tag/2.01) and see if that fixes the "incomplete write" error. If it doesn't then ask for your Duet to be replaced under warranty.

tec_bamm · 9 Oct 2018, 09:17

Thank you for your reply! I completely forgot to re-name the file inside the sys file for the WiFi Server, previously, so it never managed to install it at all.

I have reset the board once more and performed the M997 S0:1:2 for the complete reinstall.

I'm currently trying to load the web server, but it's taking a long while to load up. Once it's fully loaded up, I'll have a check on its connection reliability, so you're also up-to-date with the information. I hope this does

Is it normal for the Duet Web Server to take ages to load upon first boot? Everytime I do M552 S0 and S1 now, it times out while trying to connect, unless I've done S1 twice.

[EDIT]

Ok, I found out why my web server was taking ages... It was because my phone was updating apps in the background, hindering the local tether bandwidth. I've disabled it now, and the web server loaded instantly - so at least that's sorted.

[EDIT 2]

So far, no disconnections have happened. It's been connected for nearly 10 minutes now, which broke it's old record of an uptime of 30 seconds, so good news as of now. I will create an Edit 3 once I have further analysis.

[EDIT 3]

It's been connected for over 30 minutes now! That's done the charm! Now it's time to sort out the configs for the printer, then I will work out on how to connect it to our office WiFi.
