Web interface AJAX timeouts
-
Happening to me as well. I get a stretch of a bunch of them in a row, and then nothing for a while. Had a print finish last night, and no timeout since then, but last night there were many.
-
As these disconnects are so sporadic, my guess is that they may be caused by temporary loss of the wireless connection. DWC doesn't allow for that, so it's on my list to allow at least one retry after a timeout.
-
Same here, about one timeout related disconnect every 15 minutes. AJAX timeout set to 20s.
-
Haven't had any timeouts yet tonight. Currently 36 minutes into a print.
-
It's really weird that some nights I get the timeouts constantly, and some nights I make it 4+ hours without one.
-
I'm seeing the same behavior here.
-
Not sure what just happened, but I had an AJAX timeout in the middle of uploading a file, and the web interface lost the ability to upload files until I reloaded the interface page (in Chrome). When I clicked Upload & Print, it would open the file selection dialog, and then upon selecting the file nothing would happen. Persisted through power cycling the printer. Reloading the web page (which took ~20+ seconds) fixed it.
-
This has just happened to me as well, except I was unable to reload the web interface without power cycling the duet
-
The AJAX errors are really my only complaint at this point, everything else has been smooth sailing.
-
Reloading the web page (which took ~20+ seconds) fixed it.
Not sure that I'm right, but it seems like such long times with page reload caused by this: https://www.duet3d.com/forum/thread.php?pid=402#p402

I'm printing now but I keep getting timeouts. I got two in a row after restarting the same print (had to power cycle the printer both times) and then this one got a ways in before it timed out. The print is still going, but I need to reconnect to increase the temp by 5 degrees. Its been 25 minutes since the DC and I still can't connect.

Nyl0cke, check out the resolution on this thread:
https://www.duet3d.com/forum/thread.php?id=38&p=2It will be interesting to see what effect this has
-
Seems like this fix is only for static files (css/html/js) coming from Duet to browser. But not for dynamic ajax responses.
-
Yeah I'm also still getting a lot of errors. About the same amount, maybe more but its a small sample size so it might be coincidence.

1. Those of you who are getting Ajax disconnects: is the Error Reason at the bottom of the box always given as timeout?
2. If you ever find that you can't reconnect after a disconnect, please try the following if possible:
A. Close the browser tab, open a new one and try to connect in that.
B. If that doesn't work, use Pronterface or PanelDue to send M552 S0 followed by M552 S1 to restart the wifi module. Then try to connect.
C. If that doesn't work, run M122 from Pronterface and see what the number of free buffers is.
-
Yes for me. I canceled the print I had going (had a mechanical problem I had to fix) and I updated the web server and now I can't keep connected for more than a couple minutes it seems. its been anywhere between 30 seconds to 8 minutes right now.
I'll try what you said when it happens again
-
-
It certainly is for me.
-
- A. Connect from another browser instance (machine) works but is slow
B. Hasn't been necessary yet and I have no paneldue on this machine
C. Will try next time if I can't reconnect
Seems to be worse after I went from wired-wifi connection to wifi-wifi after I moved my laptop. Upload speeds dropped to ~250k (even seen 30-40k on smallish files!).
Hope you can find a fix for timeouts as well as speed.

Okay, If it disconnects I can not reconnect by opening a new tab and trying to connect. If I connect to the board via serial I can turn off the server and turn it back on and I can connect.
I can leave it connected but I can't test while printing for a while, the mount I used for my hotend isn't working very well, the hotend is moving around in its mount (flying extruder) a good 3mm or so.
I also tried reconnecting on a different computer to no avail.

I've been chasing timeout problems on my thread here too. I also can not reconnect after a timeout but can do things from PanelDue. When I first commissioned Duet WiFi using the installed firmware, it was up and running for well over 48 hrs with no time outs. I then attempted to install a custom DWC.bin (simple hack) and it has been disconnecting within 1 minute since and once disconnected, I can't stay connected. I copied and pasted all of the error dialogs and exactly what I did on my thread. I'm now going to go back and reinstall all of the original binaries and see what happens and do some network captures in wireshark.
-
I think I've always been able to reconnect without power cycling. Maybe once did I have to, otherwise a reload of the page or clicking the connect button worked.
Have not upgraded to the recently released firmware though.
