Yes it is that bug, thanks I'll try the fixed build in pastebin so i can get the M122 output.

@droftarts

SD card checks out ok, also the 500 errors I get shouldn't be requiring reglular loads from SD, I'd say SD failure is more likely to impact loading the site pages themselves not the API server, looking at the code.

But moving Z for example when not printing doesn't.

@dc42

Updated to 3.4.2rc2. Updated DWC and the Wifi server as well just to be sure. Problem still persists.

M122 causes my machine to reset with no output to console beforehand (tried telnet and via DWC) . Sorry how am I supposed to use M122 ?

Also reinforcing either interference or too busy microstepping. Call me crazy but the disconnects seem to happen very much around the time of a layer change. (I don't have the slicer inserting any gcode for layer transitions)

@dc42

I have everything set to x16 microstepping and interpolation, other than the coupler that has the interpolation disabled in the default E3D provided config)

M350 E16:16:16:16 I1
M350 C16 I10
M350 X16 Y16 Z16 I1

C being the coupler (this is an E3D Toolchanger)

Recently I added:
M350 A16 I1

A axis being the height adjustment stepper for my Pebble Wiper

@notepad

Oh now that is interesting as I recently added another stepper and a servo for a wiper solution, and thinking about it I don't think I had this problem before then.

There is no reason for either to be powered whilst printing, so I'll try adding something to power them down and see if that makes a difference.

@phaedrux

Sorry for the delay.

When it happens I am getting a 503 from the API

Tried turning the console refresh down to 1000ms as the default of 250 seemed excessive. But issue still exists.

@phaedrux

Sorry should have said, Duet2/Duex5.

Browser, mostly use Firefox on a Mac, but have the same issue with Safari, and Firefox on Linux

I have a strange (and recent issue).

DWC keeps disconnecting (regardles of client I connect from) but only whilst printing. (see below)

I don't think this is a network issue as duet2 doesn't report any network disconnects and if I run a constant ping in the background I get 0% packet loss, even at the same time the web client is disconnecting

Other things (such as a gcode transfer are never interrupted) and if the printer isn't printing it almost never occurs.

Version 3.4.0

It has only recently started to occur, most recently I upgraded paneldue to 3.4, but have made another few changes such as enabling a servo on duex.pwm5 (on my duex5 board) for a wiper and configuring pressure advance. but it's hard to see how these changes would have caused it. Are there any particular diagnostics I should look at?

@droftarts

Thank you, hadn't even noticed that my paneldue version should match, updated and problem is resolved.
