Web interface - shutting down during printing

[chrishamm]

@jan-doubrava You could do this either via USB or register a trigger via M581 and use an external switch. Nevertheless it would be nicer to resolve this problem but I am not sure what exactly could be causing your problem. Unfortunately I cannot reproduce it with my printer. Perhaps an M122 dump will help.

[gnydick]

I've had this happen when rapidly clicking the baby-step button

[dc42]

@Jan-Doubrava, have you tried pressing F5 to reload the web interface?

[atfphoto]

This may be totally unrelated but I was having the same problem with the Ethernet port disappearing during long prints. Usually after the first hour or so.

Turns out my motor and motor cables were not grounded. After I installed shielded cabling, the problem has never reappeared. Even with 23 hour prints I haven't had the problem return.

Could be static.

[gnydick]

@dc42 yes, and disconnected and reconnected the cable.

update - issue not resolved
printer was not running since last time
today small 2h print, web interface is down
I canot connect with pronterface for M122
repetier host returns after connect atempt

I suspect babystep button. testing if it is related

Still not working

[dc42]

Is it still giving that "JSON error: unexpected token" message when you try to reload DWC, or was that a one-off message?

[Jan Doubrava]

@dc42 yes, only M999 helped

[dc42]

Next time you get that JSON parse error message, please press F12 to get the developer console. It should display the complete unparsable JSON response. Please post that here.

[Jan Doubrava]

Is there a way to log info from web control into file? I need the info that has been lost douring the WC shutdown. (print time etc.)

[dc42]

The print time is already logged to file if you enable logging using M929.

1. Did you have just one browser connected to the Duet before that happened, or multiple browsers/devices? I'm trying to work out what provokes this situation.

2. I have made a change for 2.02RC6 to return a 503 status response to DWC if the firmware runs out of buffers. I hope this will allow the apparent deadlock to be broken.

[gnydick]

@dc42 I got the 503 error but the dwc still went dead after several minutes. It won't even TCP handshake on port 80.

[dc42]

Is this still happening? There were changes made in RRF 2.04 and 2.05 to address the issue with running out of buffers.
