Web interface - shutting down during printing

chrishamm · 22 Nov 2018, 12:24

You can reboot WiFi by creating and running a macro file that contains

M552 S0
M552 S1

When the printer becomes unusable again, could you send the output of M122 from a USB connection?

Jan Doubrava · 22 Nov 2018, 12:57

how do I run that macro when I can not connect to a web interface?
"M122: Diagnose" surely I can.

chrishamm · 22 Nov 2018, 14:15

@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.

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

dc42 · 24 Nov 2018, 23:54

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

atfphoto · 25 Nov 2018, 00:46

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 · 25 Nov 2018, 06:14

@dc42 yes, and disconnected and reconnected the cable.

Jan Doubrava · 29 Nov 2018, 15:06

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 · 30 Nov 2018, 09:49

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 · 30 Nov 2018, 15:34

@dc42 yes, only M999 helped

dc42 · 2 Dec 2018, 19:26

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 · 6 Dec 2018, 08:16

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 · 6 Dec 2018, 16:38

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

@jan-doubrava said in Web interface - shutting down during printing:

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.
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.
