Bug?: Tool and Heater/Sensor Relationship Switching Around
-
Hi all,
I have two chamber heaters configured on my machine, one of which heats the actual main chamber, and one which heats a filament dry-box.
For the most part, it all works fine. However, DWC commonly decides that the sensor and active/standby settings attached to the drybox should be attached to the main chamber. I have not nailed down when this happens, there seem to be multiple provoking factors; A print starts/ends or I just walk away for a while... and bam, DWC is confused.
It should look like this (look at chamber tool/heater columns)
But sometimes decides to reconfigure tools/heaters to this
It attaches Chamber 0 to the "Dry-Box" sensor, instead of the appropriate "Chamber" sensor. Current, Active, and Standby columns all attach to Chamber 1 in this state; the current temperatures will change in lockstep, and if I change the Chamber 0 active/standby settings, it seems to be Chamber 1 that actually is commanded to change. So basically, the Tool is still saying "Chamber 0", but everything else on that row is behaving as it would if it were "Chamber 1".
I suspect that this is a DWC bug, because any time I reset the machine it always reverts back to the way it should be, then eventually (and always, eventually) gets confused at some point. It never spontaneously fixes itself, only spontaneously breaks. Since it's always correct on reset, it makes me think my config is good, but here are my heater configs:

If someone knows how to fix this, it's much appreciated, otherwise, consider it a bug report!

@Maestro Is there another instance 'talking' to the chamber heaters? Like a macro or slicer start code?
Maybe there you've scrambled the setup? -
First I would try clearing the browser cache and doing a hard reload of the page. Maybe even re-upload the DWC files for 3.4.5 just in case.
If it's still occuring, I would try another browser to confirm.
Then perhaps try with the 3.5 beta to see if it's a bug that's already been resolved.

Thanks Phaedrux, I had tried all of that with no luck.
o_lampe wins the prize, my end-of-print macro contained
M141 H2 S0 M141 H3 S0When it needed to contain
M141 H2 S0 M141 P1 H3 S0Sending "M141 H3 S0" immediately--and unsurprisingly--replicates the problem, so, there we go.
Thank you both very much! My printer otherwise seemed to be in perfect working order, so this was really bugging me more than it needed to.
