Many disconnects - Duet Ethernet
-
I'm getting lots of disconnects and it's a big problem. I usually have to restart or reconnect multiple times every time I want to upload a new file/print. But it's not just when uplaoding. I get disconnects all the time and some times I see DWC grays out and disconnects while working in another window.
I have not found any spesific pattern.
I have Duet 2 Ethernet 1.04, the only thing is that I'm using an ASUS media bridge to give it wifi. I have no cabled network there now. Considering setting up my mac to share internet with it or an RPI. Pinging constantly shows no disconnects. My router shows no issues. and good connection
I'm able to log in to FTP but not upload or download any files. I was able to create filaments directory as it kept complaining about it missing. It seems the FTP connection is stable.
Some issues I see:
- Spurious disconnects
- Seems the browser doesn't always want to connect. The page stops loading without any error and is blank.
- Failed to get file list, network error
- Failed to upload dwc2settings.json, Could not complete action because the connection has been terminated

@strips I can't see anything particularly obvious, and no errors are being generated. The power supply seems a bit variable:
Supply voltage: min 23.7, current 23.9, max 24.1
Is it in good condition? Check main power cables are making good contact and are in good condition, so there's no ground leakage via other wires. Does it happen only when the printer is running, or just heaters on, or at any time (even when printer is idle)? Could be interference related.If it's happening during file uploads, it's possibly SD card related. Have you tried backing up the SD card, reformatting it with the official SD formatting tool from https://www.sdcard.org/downloads/formatter/index.html, and copying the files back on? SD card issues was actually my first thought.

Thanks for the reply.
I'm pretty certain it happens with heater on or off but I need to verify that. I have not found any ground issues. The PSU is stock Ender 5 Plus and I have all stock heaters. Just a smaller motor on the Titan extruder but that should use less current.
I have tested two SD-cards and had the same issue with 3.01-RC5 and 3.01-RC6. When upgrading to 3.01-RC6 I reformatted and copied over the new Duet Web Control 2.1.0.
I just got the following error as well. I have seen this multiple times.
"Failed to upload dwc2settings.json
Could not complete action because the connection has been terminated"This is how is usually is. The bed heater was on during these disconnects:
-
@strips Hmm... frustrating one. I'll share this with my colleagues, see if they have any ideas.

logging a session with wireshark might help shed some light on the issue, but i'd be very temped to rule out wifi of the equation.
-
randomly searched for a post of dc42 recommending grounding and this was the first post; suddenly seemed very relevant.
-
I need to check how the frame and motors are grounded. I have some electronics background and I would prefer not to have a reference between the high voltage side and the low voltage side. Any noise/static should affect both V+ and V- and cancel each other out. I need to borrow a scope
@bearer
Logging network traffic could be done. Not exactly sure what I would be looking for.As an update I get just as many disconnects while no heater or motor is running. Well the motors were holding so some current is passing through. I'm just to start a new print so I'll have to verify tomorrow.

@strips I agree with the above, that you need to try it without the ASUS media bridge. I'd guess wireshark would show up if this was the problem, though.

me neither, but if you upload the file I'll take a look tomorrow. preferably without a capture filter
-
Ok,
I still need to eliminate the media bridge and analyse the traffic. I could just make a long TP-cable running down the stairs. My wife would freak out but it would only be temporary
Update:
I'm getting the issue with nothing turned on. I just tried to upload a file and i got a disconnect. Then I did a M999 to reboot. The first command after opening a new browser window 3 minutes after was M122. I got the output printet in console then a disconnect immediately after.08/04/2020, 10:53:01 Connection established 08/04/2020, 10:52:59 Failed to upload dwc2settings.json Could not complete action because the connection has been terminated 08/04/2020, 10:52:59 Connection interrupted, attempting to reconnect...

@strips Unfortunately, I can't see anything obviously wrong in that M122 report because the reset has cleared any errors. Is it possible to connect a PC/laptop/RPi to the USB port and log the debug information? If you can, send
M111 P1 S1to log network debug info, andM111 P2 S1to log webserver debug info to the USB port.If you can run a long cable to it, it would remove one possible failure point.

I just bought a RPI 4 and Pi-cam to use on the printer. I'll let the RPI be the wifi-bridge. Then I can have a closed network between RPI and Duet. It gives me the best way to analyse the traffic as well.
Just bear with me a few days and I'll report back when I got everything running. Depending on my wife I could have it fixed by tonight...
-
haha, with respect to the other issues is usually easier to get acceptance* if you present a worse alternative; i.e either there is a cable running downstairs, or the printer comes upstairs. Suddenly the cable looks like good option.
*) but you'll still "pay" for it I guess..
-
@bearer said in Many disconnects - Duet Ethernet:
if you present a worse alternative
Better still, don't present it, when she says no cable simply start to carry the printer upstairs. When she SEES the alternative she'll insist you run the cable.
