I'm a step closer to the root of that issue. It seems that I have a "block" somewhere in my kernel. There are a couple of reports that the X-Windows system and the linux kernel have some problem with internal blocks of processes when the system runs low in memory. I have that problem at the moment with 100% memory usage plus 13GB swap. The CPU load is around 10-12. On a Threadripper with 24cores and 2 threads per core.
You may to make sure that you do not have a problem with your host. :?

Update: I restarted the bloody Firefox (Beta), that gave the Chromium enough resources to communicate properly with the Duet.
This modern browsers open a lot of tcp connections and keep them open for a very long time. You may like to test if you have that problem with a fresh started workstation.

I have bought a brand new duet 2 ethernet board and am still having the same problems. Was hoping using an ethernet board would help.
I updated the new board to firmware 3.1.1 and this is my results for M112 immediately after it reconnectsM122

@mike5490 said in Random disconnects DuetWifi 3.01 RC12:
After updating to the official 3.1.1 it seems to disconnect less randomly and seems to occur most often after an endstop is triggered while homing.
Are any of the endstop switches connected to the DueX5?
-
@mike5490 can you post your current config.g, preferably in you reply as text using the code tags? (I can’t read attached files on my phone!) Are you using a fixed IP address (possible IP address clash)? Have you tried connecting to the DWC using a different device (phone/tablet/PC)?

I have tried both a fixed ip address and one assigned by the router and it hasn't helped.
I have tried connecting on my desktop (windows 10), macbook pro, ipad, and iphone and the same problem happens on all these devices -
@mike5490 said in Random disconnects DuetWifi 3.01 RC12:
As the disconnections seem to be happening when endstops are triggered, and particularly because you are using plug in connections (very tidy, but each pin is not insulated from others on those connectors, by the look of it), trace the endstop wiring very closely from board to endstop, through those connectors, and check there's no wire strands shorting out on another pin. Do disconnections happen on both X and Y endstop activation?
Other possibilities:
What endstops are you using? I can see you have 3 wires going to each endstop connection. If you're using bare microswitches, you only need to wire two wires. The third may be causing interference on endstop activation.
Check you have no wiring running alongside, or parallel to, the ribbon cable connecting the Duet and Duex. Ribbon cable is unshielded, so can pick up interference, causing false triggering or interrupted signalling. Your probe wires are close
Maybe extend the endstop cables and connect them to the Duet, and see if the problem disappears?
I know in your first post you said you have tried a different SD card, but did you try a different SD card when you swapped the boards, or are you using the same one? I'd try using a freshly formatted card, using the official SD card formatting tool. For SD card specification see https://duet3d.dozuki.com/Wiki/SD_Card#Section_Specification and the section after for formatting. There's also a section on testing write speed on that page.
I can't see anything obviously wrong with your config.g. Note that in M92, M566, M203, M201 and M906, only Extruder axes can have extra parameters (because each is an extra axis); other axes can have only one parameter, so replace all the 'Z[nnn]:[nnn]:[nnn]' with 'Z[nnn]' in these gcodes. The firmware should just ignore the extra parameters, but in older firmwares it caused problems.

I'll double check the connectors for any shorts tonight.
Yes the disconnects happen on both the x and y axis endstops, it doesn't seem to happen more often on one or the other.These are the endstops I'm using. I had them wired in the same way on the previous version of my printer and didn't have any issues.
Currently I'm using the new SD card that came with the new board. I'll try a freshly formatted one too.
-
Did you have the endstops wired like this? https://duet3d.dozuki.com/Wiki/Connecting_endstop_switches#Section_Makerbot_Mechanical_Endstop_v1_Num_2
-
One possibility is that the Y endstop wires are picking up noise when it is triggered (assuming it is a normally-closed switch) and that is causing an excessive rate of interrupts from the DueX5 to the Duet. In which case, one of the following may resolve it:
- connecting it to an endstop input on the main board instead
- using shielded cable for that endstop
- adding a pullup resistor between that endstop input and +3.3V (between 1K and 10K)
- adding a small capacitor (e.g. 1nF) between that endstop input and ground
-
After extending and moving the y-axis endstop connector from the duex to the duet I haven't had any more disconnects and everything seems to be working correctly.
Thank you so much.

@Phaedrux I get a lot of these disconnects using Vivaldi to run DWC and far fewer disconnects when using Google Chrome.
Vivaldi allows the user to reload tabs at user specified intervals but this doesn't seem to help.
Vivaldi is based on Chrome but has it's own settings for tab hibernation. Sadly it cannot be turned off. People would like control over this but so far there is none.
I should search for a browser that doesn't hibernate tabs and just use it for running DWC.

@gbartsch You can run a web page as a chrome app. That might give you more of what you want.
First you can turn off tab sleep
Go to chrome://discards/ (open as a URL).
Find the tab of interest.
Look at the "Auto Discardable" column, click "Toggle" to disable it.then you can make it appears as an app window rather than just a tab.
Add a shortcut to a website as an app
For Windows, Linux, and Chromebook users, you can add a shortcut to a website on the internet as an app in Chrome.Open Chrome.
Navigate to the website you want to add as an app.
At the top right, click MoreMore.
Click More Tools.
Click Create shortcut.
Enter a name for the shortcut and click Create. -
@Phaedrux Thank you! I've done this and will test it for a while.
