DWC intermittently stops tracking job data

kingofthegeeks · 10 Apr 2021, 05:10

On occasion while running a print job the DWC stops displaying job related data and all the fields are blank except for the slicer job time. Its been kind of annoying but hardly a big deal until it happened on hour 3 of a 72 hour print.

I'm assuming there is nothing I can do on this print job but any ideas when its complete ?

@kingofthegeeks
You could configure auto-safe on power failure (M911).
When it happens next time, just pull the plug and restart everything (including browser, just to be sure)
If the duet board had enough time to safe the data, you can see a resurrect.g file in /sys folder.
Run it, or send M916 or use the 'resume print' button to start from there.

It's a good idea to test pause/resume and power failure behaviour on a less important print

@o_lampe seems like a reasonable solution, so I guess this is a common occurrence and to be expected then?

@kingofthegeeks
I can't tell if this is to be expected. I have used it during printer setup a few times ( after I hit 'pause' but not 'cancel job')

I've lost DWC connection twice last week on a Maestro-ethernet with 12864 LCD. (*)
It would be cool to write a daemon.g job, which checks for interrupted connections ( WiFi, ethernet and LCD/PanelDue) and calls pause -macro. But I guess that would trigger too when I close the DWC window. @chrishamm or @OwenD is there a way to detect a real connection lost error?

@kingofthegeeks What firmware and DWC version?

When this happens is DWC completely disconnected from the Duet? Are you able to reload the page?

If this is a Duet Wifi is the blue LED on the module still lit up?

Can you provide the results of M122?

@phaedrux

I can reload the page, everything seems to be reported as expected with regard to positioning, tool and temps but there is no job specific data available such as time to completion or layer data etc.

@phaedrux
As for disconnecting, I am unsure, when I set up the print and started it everything appeared to be working fine, when I returned a couple hours later there was no job specific data. I really appreciate the attention to the matter but its not a critical thing for me.

Thank you.

@kingofthegeeks said in DWC intermittently stops tracking job data:

It sounds like DWC tab has been slept or something and the data for the layers etc isn't being captured during that time.
