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.

again

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.

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.

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.

richardmckenna

@dc42 Recently, I'm seeing this on a my Duet2 WiFi running 2.x not sure of the exact version, but will check when I go home at lunch. I've not updated it in a while as other than this it has been running fine.

I access DWC to start the print usually from my iPad, leave the browser/put the iPad in standby or something along those lines. Go back to check the status an hour or so later, refresh the page as it says it has lost connection, it will not load.

The strange thing about it, up until a few weeks ago it did not happen and connected fine each time. I've not updated the firmware on it in several months.

Let me check what Firmware/DWC versions I'm running and if needed I will update to the latest RRF 2.x to see if it still happens.

richardmckenna

@dc42 yeah I’m on 2.03RC5 so I will update and see what happens.
