Duet control no longer shows in the browser

drthomasw3

I can no longer see Duet control in the browser. The console on the printer says connected. The browser shows connected no errors but blank.

which browser/operating system?

try a private/incognito tab, this will ensure there is no (local) cache issues and may prompt an error.

No joy on incognito! Tried Chrome, Explorer Page is unsecured but I have allowed permission to access. The same goes for my laptop. I have been using web control fo months and several hours today. Suddenly nothing. I took out the sd card and checked that nothing changed in the network settings of the config.g and reseated the card. The printer is working fine. I am currently printing via the touch screen because of this issue. Hopefully, someone has a suggestion

two things; firstly try specifying http:// in addition to hostname / ip (to avoid issues https)

secondly see if you can open a new tab, hit F12 to open developer console before entering the address, if it fails there will be some clues in either the console or network tab.

Failed Https the tab had the Duet icon in front of the address but the screen was blank
With the developer console Message, this sight cannot be reached.

you missed the : in http://10.9.65.119/ <- that should eliminate any typos

then if that still doesn't get you anywhere, it would be the Response part of the headers that would be of most interest.

drthomasw3

Http://10.9.65.119 changed to 10.9.65.119 after hitting enter. nothing showed up in the console

No reply; wrong thread.

What is the Response part of the headers ?

A Former User

The picture you posted only showed what the PC sent the Duet. But as the URL was malformed in that case nothing was returned. If you start fresh with a new incognito tab, open the developer console and type in the url http://10.9.65.119/ it really ought show what we need to know to determine where to look. If nothing is shown then the problem is likely local to the computer somehow.

Well thats interesting! You're actually getting an empty reply, unexpected..

Either somehow the /www/index.htm(l?) file on the SD card is corrupted or something stole your Duets IP address and you're actually connecting to something else?

M552 on the console should print your Duet IP just to confirm. Alternatively download fresh DWC files appropriate for your firmware version and try to update the /www folder on the SD card.

DWC files

When I start the Duet the screen on the display says: WiFi module is connected to access point
"My network with correct IP address"

What firmware version are you running on the Duet?

It is unlikely to be a problem, but verifying the IP was just the first step, to be 99% sure you're actually talking to the Duet, we'd need to confirm the MAC address as well. It will be part of the M122 output, and running arp -a on the command line on the computer* should allow you confirm they match.

I think I'd confirm the version as dc42 asks for. Output of M115 for RRF firmware version and M122 for the DuetWifi firmware version, then proceed from there.

edit:
*) shortly after trying to access the web interface, otherwise the MAC address will not be in the ARP cache.

RepRap firmware for Duet 2 WiFi/Ethernet FIRMWARE_VERSION: 2.03 ELECTRONICS: Duet WiFi 1.02 or later FIRMWARE_DATE: 2019-06-13b2
Thank you

the M122 gave info about ram but no MAC information. The arp -a command, showed the IP and MAC for the Duet

drthomasw3

I just ran M540 the MAC addresses do not match Duet looks odd a5:a5:a5:a5:a5:a5

A Former User

It should be under the Network section of theM122 output, something like (if your terminal line ending is not set to LF it could be truncated)

WiFi firmware version 1.21
WiFi MAC address 60:01:94:nn:nn:nn

known "bug", for wifi its part of M122.
