Duet WiFi web interface only half working

niik

I am having some issues using my Duet Wifi.

The problem started as a file upload issue. I was not able to upload any files larger than about 100KB. I was using Firmware version 1.19.3 when the issues all started.

When I tried to upload gcode files they would fail. I hadn't updated the firmware in a while so I figured id start with that since it was a good idea anyway. Uploading the first couple Bin files worked fine. When I tried uploading the web control files the smaller ones (<100KB) worked fine but the larger ones failed. I then removed the SD card and loaded the files directly to SD. The firmware upgrade completed and the web interface loaded, connected to the printer, but still would not let me upload gcode files.

Next, I figured it could be the SD card so I got a new one and copied all the files from the old SD to the new one. I put that in the printer and nothing worked. Turnes out I bumped the erase button and deleted my firmware. So out comes the USB cable and I follow the directions to get firmware back on the board. Everything seems to go according to plan, no error messages or anything. Once the firmware is loaded again and the new SD card is installed I try to load the web interface.

Now for my current problem. The web page loads partially, sometimes more than others. when I load the page I get a range of results. Sometimes it just loads unformatted text, other times it loads the whole page but its non-responsive and only shows "printer disconnected" status. I have tried reloading all the parts of the firmware; Duet2CombinedFirmware, DuetWiFiServer, and DuetWebControl just to make sure I did it right. None of my efforts have been successful at resolving the website issues.

Other odd behavior I noticed is when I connect over USB using Repetier I get a "No start signal detected - forcing start" message but the connection continues and I am able to send commands to the printer. Also, I get random disconnects while connected USB.

Connection and M122 results

Webpage screen shot

Thanks for your help. I am out of ideas.

Scachi

I had this issue with the page showing up like that too some time ago.
I cleared my browser cache (firefox) and tried a different browser, both without success. Opening the webpage from my phone did work.
Rebooting my router (fritzbox) did the trick finally.

Danal

Clearing cache, different browser, different device, all good advice.

Reboot the router? Hmmm... must have some interesting proxying going on in that router. Or it doesn't like parallel TCP streams between local devices, or ...

Certainly worth trying. I have had Duet not get on the network at all, until the router was rebooted. What a PITA.

Danal

Also, when you upload new firmware via the web interface, it both uploads the files to the /sys directory and installs them into the flash memory on the board and/or wifi module by issuing separate M commands.

If you've had trouble getting this to work, it is at least possible that your alternative methods (physical copy to the SD, etc, etc. ) got the files to /sys, but never loaded them to the board(s).

As such, repeat the uploads via the web interface, or if that is too broken, look up the G-Code to actually install the firmware. Be sure the files on the SD /sys are correct, and issue those commands.

niik

Thanks for the recommendation. I got momentary success but lost it again.

I had previously cleared the cache but it didn't fix the issue, but I had not restarted my networking equipment. I had also previously removed and re-added the pairing in the access points web interface but that did not resolve the problem.

Restarting the access point, router, and switch and also clearing cache fixed the problem. I'm not 100% sure what action resolved the issue this time since I did them all at the same time.

I was able to connect to the page for a minute but then got another error "request timed out."

List of actions.

clear cache in Edge.
restart network equipment
restart duet
connect to the webpage using edge
everything working, uploaded gcode. FIXED!!
try connecting using firefox (my main browser)
page half loads (Img 1) in firefox, at the same time I get "request timed out" in Edge window (Img 2) BROKE!!
close both browsers
restart duet
try connecting with Edge "page cant be reached"
repeat steps 1-4
"page cant be reached"

Throughout all of this, I am watching ping and am getting responses when I should.

We were so close.

Thanks for the advice. I followed the guides and due to my own mistakes had to go as far as flashing a fresh firmware using USB and BOSSA since I accidentally delete everything. I am getting USB connection now and the board is reporting 2.04RC1, and webServer 1.23 with webControl 1.22.6 which is the firmware I was trying to install, so it seems like the process worked. However, the firmware upgrade mostly seems to have made the issue worse since originally I could connect fine just not upload but now I can't even connect.

This is absolutely key. Given that you can ping, the network is functioning correctly.

So... even though we think it is all good... re-flash the Duet. Specifically:

Be sure the sys/Duet2CombinedFirmware and sys/DuetWiFiServer.bin files on the SD are the versions that you want. A fresh download won't hurt.
Issue M997 S0:1 and wait for it to complete!!
Power Cycle the Duet

After more troubleshooting, I have no idea...

I tried updating the firmware using fallback procedure #1 (as @Danal recommended) and ran into some more issues, details below. I have also included another m122 result since I am now seeing errors in the console maybe the m122 will have more relevant info.

Actions:

downloaded firmware
Duet2CombinedFirmware.bin (from 2.04RC1)
DuetWiFiServer.bin (from 2.03)
iap4e.bin (from 2.03)
loaded to SD card
connected to board over USB using repetier
sent M997 S0:1
waited for completion (console counted to 100% then I listened for the USB device to disappear and reappear)
5)restarted
pressed connect on Repetier → "Com port does not exist"
try the other ports. still not working.
check device manager → "Bossa port" showing instead of Duet
decide to try another firmware version
download Duet2CombinedFirmware.bin, DuetWiFiServer.bin, DuetWebControl.zip, iap4e.bin from version 1.21 and load them to the SD card
loaded firmware using "BOSSA" app following fallback procedure #3
connect to Duet over USB issue M997 S1 to load the WiFi server that matches the main.
restart
try to connect to webConsole → half loads. (img 3) and console reports Error: Can't open 0:/www/img/diabase_calibration_diagram.png.gz to read, error code 1
I get multiple of those errors depending on what is trying to load.
remove SD And check that the files are on it. They are.
delete and recreate the www folder and extract the WebControle files to it again
put SD card back and try again. same issue

Another observation is that after I try to connect to the webpage sometimes the Duet disconnects from USB and I drop like 2-3 pings, so it seems like it is getting reset.

I get multiple of those errors depending on what is trying to load.

That is really odd. There is no such file in a Duet's /www directory as distributed. In fact, there is no such directory as /www/img. DWC does not use images (png).
(It does use a favicon.ico.gz file, but no other images).

I do see that the functions that are built into DWC to automatically put various files in their correct directory, by file extension, WILL build a /www/img directory and put any .png, .jpg, or .jpeg files there. So, at some point in the past, some files with those extensions got uploaded.

My advice at this point:

First, try to fix the www directory:

Put the SD in your PC and delete /www (and everything under it). Back it up first, if you wish.
Download DuetWebControl-Duet2.zip This is R2.0.0-RC7, which should work fine with the firmware you've loaded. If you want another release, see here
Unzip it into a new, empty /www on the SD. After the unzip, the directory should look like:
css (dir)
fonts (dir)
js (dir)
index.html.gz
favicon.ico.gz
... and maybe one or two other files, but NO 'img' directory!
Put that in the printer and see what you get.

If (and only if) that does not work, build a physically new SD. Be sure and start by formatting the new SD as a "FAT32", and be sure and UNcheck "quick format". Then copy stuff over. Including the newly built www directory.

Shaun

I had the exact same. so this is what i had to do to fix this.

Check your wifi security on your router. duet doesnt seem to like multi mode authentication. Set your router to WPA2-PSK and your problem should be resolved. It wont drop off and the browser will work fine.

Formated another SD card using SDformatter.exe with settings FULL(overWrite) FORMAT, SIZE ADJUSTMENT ON. The card was previously used in a Pi so I could not format it with windows until the Linux partitions were removed.

Confirmed FAT32 file system

Copied all files from SD1 to SD2.

Results: FIXED!!!

Page loaded and connected to the printer. I uploaded a file a ran a test print.

Couple small errors

M141: not chamber heater has been configured for slot 0
Failed to get file list - directory 0:/filaments not found

I think these are relatively self-explanatory errors and I can work through them.

Summery

After all the stuff I think I have an idea about how everything happened.

I had a network issue that caused my original upload problems.
1.1. Updating the firmware was probably not necessary
My first and second SD cards were bad leading to unexpected and unpredictable results.
2.1. SD1 has been in since I got the board so could have worn out.
2.2. SD2 is an almost new card that was used for pictures like once. So must have been defective or the format I ran on it when I first set it up completed with unknown errors.
SD3 was a card I had in a Pi and it seems to have fixed the issues I was having.

droftarts

SD card specification for Duet is here: https://duet3d.dozuki.com/Wiki/SD_Card
(I've just updated the bit about formatting, and size limit)
For M141 error (it's Cura) see: https://forum.duet3d.com/topic/11546/cura-4-2-1-to-duet2wifi-plugin-problem
You need to create a filaments folder on the SD card.
