Duet 2 Ethernet WC 3.3.0 crashes, have to reset to reconnect

trobison

@dc42 G'day dc42. Can you provide a way to test the ports on the DueX? I can move the servo to the next port, reconfigure the config.g and send a command to move the servo, but nothing happens. When I configure them from the console, no errors are present. It looks like hardware, but you are correct. It could be a bug.

@trobison I have tested this on my setup and cant see the difference between 3.3 and 3.4

As a complete test you could try temporarily downgrading to 3.3 and see if it changes the result.

@t3p3tony I completed this task earlier on 4 April. There was no difference with the servos, but the network does not disconnect and reconnect with a M122. I still can't get Ports PWM5 and PWM5 to function.

@trobison ahh apologies i missed that. in that case it looks like a hardware issue. not sure why it would come up in sync with a firmware update. Please email warranty@duet3d.com highlighting this thread.

Hey, just removed a part from the bed, without moving it, just a smack with a wooden handle, came back to desk and duet disconnected.. really thought I had figured this out but bed movement is not what is doing it.. would explain why I can not reproduce it on demand by moving the bed..

@airscapes I am seeing a very similar situation. This was completely stable until 3.4.0 for me, and after that upgrade my Duet 2 Ethernet drops connections to DWC randomly, and once cost me a big update to a macro I was doing as it crashed out.

Now I don't use DWC to edit anything because its liable to reconnect often through the entire print, or even at idle! Same error you are seeing, with no change in config other than the firmware being updated.

@airscapes You have filament sensors on your printer (rotating magnet style?). I noticed tonight that my DWC instance will crash and need to reconnect if I have mine enabled, I posted about it in another thread.

Nope, only magnet is on the door to the enclosure and that is far from the Duet. Being an IT admin and before that an Auto Mechanic.. this issue is very odd, not being repeatable on-demand is really annoying. My board was replaced but the replacement had a serial number that was 2 off from the first one. The Ethernet module was also replace and the drops still persist. I have seen it drop and reconnect a few times as well.

This issue is still alive for me and getting worse. It is heat related as after half a day of printing when removing the part no matter how gentle I am, the network drops. I have even tried locking all motors so as not to cause any voltage spikes with no avail. The ground of the duet 2 is not attached to the frame and I do not think it matters, duet 3 does not have this issue and no external LCD on either. The Ethernet module was replaced with no change in behavior. Getting tired or powering off and on, reloading height map and micro steps after every print job. Any other guesses? firmware is fairly up to date at 3.5.2 and when it was updated to that, no change in behavior. Not expecting an answer just frustrated and grasping at straws..

@airscapes it would be worth updating to firmware 3.5.4. If your system includes a PanelDue, please update that to the latest firmware (3.5.1) too.

airscapes

@dc42 No PanelDue.. it is really heat related.. If I print TPU no issue.. bet set at 70 or more issue arises..
I have been just using the machine with the Duet 3 as I don't want to deal with resetting everything after each job..
