Tips for autotuning a very large heated chamber?

chrishamm

@p8blr Can you press F12 or open the dev tools in your browser session and check for potential errors in the console? If nothing shows up there, can you please check the duetcontrolserver log? See the section about journalctl in https://github.com/Duet3D/DuetSoftwareFramework/wiki/SBC-Setup-Guide#increasing-log-level.

It doesn't look like DSF loses connection to the Duet so I suspect something else is going on.

@chrishamm I'll have to put that code back and run a PID autotune again, I'll get back to you with an update.

p8blr

@chrishamm I changed the settings and restarted and got the error, I didn't even have to autotune.

journalctl -u duetcontrolserver -f

Also I should mention that putty freezes up very frequently when this error happens.

chrishamm

@p8blr If PuTTY freezes as well that probably means the Pi stops working at some point. In that case I'd rather check the electronics again. Are you operating the Pi from the Duet's 5V rail? If yes, consider removing the 5V -> SBC jumper and hook up the Pi to an external 5V PSU.

p8blr

@chrishamm I'm powering the pi via a usb C supply. My suspicion is that because the freezing happens at a regular pace, perhaps it has to do with the daemon.g. Is that possible?

chrishamm

@p8blr I need the full DuetControlServer log to answer that. Your excerpt didn't show anything significant.

p8blr

@chrishamm How do I generate that?

chrishamm

@p8blr journalctl -u duetcontrolserver --no-pager -b

@p8blr I believe this is a duplicate of this report. Can you try out one of those DWC builds and check if it is fixed then? See here.

@chrishamm I can, I'll get back to you on it...

p8blr

@chrishamm So far I'm not getting any more issues connecting to the web interface with the heaters combined now, just errors that the DWC versions don't match.

@p8blr have you refreshed page? this bites me on occasion on upgrades!

p8blr

@T3P3Tony refreshing the page seems to work fine. I know what you mean though, sometimes before when I refreshed the page it wouldn't reconnect.

T3P3Tony

@p8blr yep if DWC is upgraded the page needs to be refreshed before it's upgraded in the version you browser is displaying!
