Web Control keeps disconnecting

Aurimas

@Phaedrux interface says "disconnected"
reconnects then after some time looses connection again
nothing to do with IP or the network - connected directly to the board and the board keeps running.
it just interface keeps resetting/relaoding

Phaedrux

Can you confirm that the DWC version is also 3.5-rc2?
What browser?
When you can't connect, are you still able to ping the Duet IP?
Can you open a command prompt window and have a continuous ping to the duet IP running? When you get a disconnection does the ping continue normally or does it fail as well?

Aurimas

@Phaedrux yes it is 3.5-rc2 - all firmware matching
it is not IP that is lost - its the DWC that throws an error when status changes from idle to disconnected and then refreshes page by itself. its not the IP. if it would be IP issue as I understand I would have to hit refresh in the browser
browser is always Chrome.

Phaedrux

Are you able to roll back to 3.4.6 for firmware and DWC and see if the disconnects still happen?

Aurimas

@Phaedrux not really - i think older version will not support my setup. I have 16 axis setup right now using 16x 1XD

Phaedrux

Yes I understand, but I'm trying to determine if the issue is hardware related or with the firmware/DWC release candidate. This is why I ask to see if the ping succeeds or fails when the disconnects are happening.

@Aurimas It looks like your board runs out of output memory, @dc42 and I need to look into it:

Used output buffers: 13 of 40 (40 max)

Do you only have a single web interface tab open when this happens? Is there a PanelDue or other display connected to your machine as well? Would you mind sharing your whole config.g file?

Aurimas

@chrishamm No screen connected, the pc is directly connected to the board via ethernet cable - so no hub or anything in between.
Config file has paneldue configured, but it is not connected at this stage

here is the config file:

; Default config.g template for DuetPi
; Replace this with a proper configuration file (e.g from https://configtool.reprapfirmware.org)

; Enable network
if {network.interfaces[0].type = "ethernet"}

@Phaedrux I have been pining target and had disconnect - ping had no issues at all.

@Phaedrux
Unfortunately I am ”able” to report the same problem.

6XD+3HC and Panel Due, all updated from 3.4.6/1 to 3.5.0 rc2.

With 3.4.6, there was not any problem in DWC, it started only after updates. Updates were really necessary, because of some other bugs, most related to Panel Due it seems.
DWC works, but it keeps disconecting. Closing web browser, rerstarting computer, did not help.

Usually I am working on Chrome, but it seemed to be the same on Opera or Firefox. In fact, I was not able to fully connect with those too, but the same was with Chrome, after restarting the computer.

I am on Win11 Pro, I3-12100 and 32G RAM, however, I think that they are not an issue... by far.

The problem is just annoying, is is possible to work... barely.

L.E. I updated DWC to 3.5.0 rc2 too. The problem seems to be solved.

I am also having a similar issue. I am on 3.5.0 b4. Uploading files is hit or miss. DWC will disconnect and refresh. If I keep retrying it will eventually work. The larger the file, the more I need to retry. It was fine when I was on 3.4.5. I upgraded firmware to address other issues.

Running 3.5.0 rc2 causes layer shifts when using input shaping so upgrading is not an option
