SBC Disconnects from Duet 3 Mini - Network error

SputnikOC3d

Crickets ?

Seems kinda big issue and one thats prior known - is there a article or thread that shows a resolution i cannot locate it via search here or on google

@sputnikoc3d The m122 output shows some errors with the SPI connection between the Duet and rPi (1 disconnect, 1 failed transfer and 4 checksum errors). The dsf log on the rPi may show more. This often indicates that there is some sort of electrical noise on the connection between the two boards. Perhaps a picture of how you have the two boards connected would provide some clues as to what the problem is?

Pics removed ... those were old and a temp setup - got underneath it and took a new photo or two --- its same pretty much but with no CLIP on there - Id forgotten I used that t form the cable over night with no power ... Ive zip tied it since

SputnikOC3d

@gloomyandy - good catches - but will be interesting to see how this relates to wifi networking not working at the same time these failures occur ... odd coincidence perhaps ?

@Phaedrux - any chance you can point me in the right direction here for threads to read - Ive don quite a bit of searching. I find some threads with related issues I think, but none of them seem to have a resolution. Several just end up ditching the SBC and go stand alone ...

I want the pi for the video out and user interface inputs vs. a panel due.

the loss of connectivity kills my objectives.

@sputnikoc3d you could try making up your own shorter cable. It only uses 5 or 6 connections

SputnikOC3d

@jay_s_uk - actually - pretty good idea. I hadnt seen that was a possible issue but Im not too happy with the way that is now - lol, and if it helps - then win-win.

@dc42 Hey man. Any help here?

I even opened a chromium browser on the pi and went to /localhost - usually that works reliably if needed - but even that had same issue a few times.
Surely the connectivity between the SBC / Duet cannot be reliant on wifi connectivity to the pi - can it ?

How are you accessing DWC if not through localhost on the pi?

If the print hasn't been interrupted than the duet and pi are still in communication.

Did you turn on the local logging on the Pi?

@phaedrux - when my system boots it automatically loads DWC in an interface that seems to be a modified chromium window in full screen mode - I see some info about ... DCS - not sure what that is.

I did not turn on local logging - wasnt aware that I was supposed to.

I am definately noe getting prints interrupted .. however if I want to say STOP the print - I get network error

If I want to M572 more PA - i get errors
If I wanted to increase fan speed - network error
Increase temps or lower temps - network errors - intermittently and usually when I see that the wifi network is temporarily not associated" with the network I see 2 red x on the network indicator icon upper rt corner

with a phrase like ... machine not associated with wlan0

Funny I come across this, I had a customer who's mini would disconnect from his tablet he was using as an AP and then reboot. And would happen randomly but only in print. Haven't been able to replicate it. Updated his firmware but still happens on occasion. Was going to take him a proper wifi AP when he gets back from his trip and see if it helps. He's running in stand alone mode though.

SputnikOC3d

@shauncro - but why should my wifi access point's functionality impact duet 3 mini and rpi 4 communicating over SPI cabled connection ?

Instruction state:

Once done, run

ls /dev/spidev*
and verify that /dev/spidev0.0 has been created.

Mine is - /dev/spidev0.1

@sputnikoc3d It might help if you post a picture of the browser interface you are using showing the errors you are getting. I assume that you are using the interface displayed on the screen you have attached to the rPi and it is on this screen that you are seeing errors?

It would also help if you explain exactly what it is you are doing and when you get the errors. So for instance, do you get an error if you boot the printer and just leave it alone? What happens if before you start a print you enter commands in the DWC (the web display console), do you get errors then? If you start a print and do not enter any commands after that does the print complete? Do you get any errors?

Yes thats exactly correct. The default screen that the dcs/dsf etc ... gives me after Ive installed the fw on the sd card running in the Pi. it launches automatically - im not launching the DWC app im given - it jsut shows up on boot and reboot of the pi. Everyone is acting as if thats not the norm ???

Its just a chromium interface i imagine without browser "options"

It would also help if you explain exactly what it is you are doing and when you get the errors. So for instance, do you get an error if you boot the printer and just leave it alone? What happens if before you start a print you enter commands in the DWC (the web display console), do you get errors then? If you start a print and do not enter any commands after that does the print complete? Do you get any errors?

Tried to explain above ... just normal actions one would take while a print is underway ... maybe like babystepping on 1st layer / changing temp / changing fan % / Emergency stop / Pause / Resume

Those commands in the DWC window if wifi connection drops - will fail to execute and produce an error in console and in the bottom right corner of dwc screen : M11-whatever... failed : Network Error

SputnikOC3d

@gloomyandy - the errors only seem to happen if the pi loses connection to the wifi. Which makes zero sense to me.
