Confusion re DWC 'control heaters'

jens55

Is there maybe a setting in DWC that I must enable to allow the 'turn everything off' button to function?

jens55

OK, this is getting really weird .... I have two printers that run Duet boards. One runs a Duet 2 wifi with a Duex board attached and it runs DWC 3.4.0. The second printer runs a Duet 6HC board with 4 tool boards. It runs Duet 3.4.4 and it is the printer that I have noticed this problem with.
I just went through all the combinations of menus that display the heaters with the 6HC board printer - none of the possible menu combinations I tried did anything when hitting the 'turn everything off' button. Out of desperation and with nothing to loose, I looked at the printer running the Duet2 wifi ..... for some bizarre reason, the 'turn off everything' button works totally as expected !!!!! WTF ???? While the Duet2 does run 3.4.0, the Duet3 had the issue when 3.4.0 was installed on it!

jens55

Yup, tried it again and yes, I press te button and everything turns off. Not only does everything turn off but the 'turn everything off' button that was blue before, changes to a non-blue version of itself. The Duet3 'turn everything off' button is blue but stays blue after it is clicked!
On the Duet3, the 'turn everything off' button is blue only if a heater is active or in standby. This is the same as how the Duet2 system works.

So .... is the inability of turning things off related to the 6HC board? Is it related to all heaters except the bed being run off tool boards? Is there something in config.g that needs to be set a particular way ?

So, it would seem that the way I am trying to operate the 'turn everything off' button is actually correct.

Let me rephrase my question based on the newly discovered info: If you have a Duet 6HC board, does your 'turn everything off' button work? Do you have your heaters running off the main board or are you using heaters that run via tool boards?

Is the Duet3 6HC in SBC mode?

jens55

@Phaedrux, I do not have an SBC connected and I use the standalone files when I update. Is there a seperate flag that turns on the SBC mode ?

Phaedrux

No, and it's not that there is a known problem with SBC or anything, just wondering what your setup it.

Maybe it's because they are toolboards? They are all on the same firmware version as the mainboard?

jens55

@Phaedrux, yes, they are all on 3.4.4 which I just installed the other day via the zip file in the repository. As far as I know, if I upload the zip file then everything gets automatically updated.
I will double check ....

jens55

Double checked - all boards report 3.4.4

jens55

@Phaedrux, which Duet board do you run and do you run tool boards or is everything connected to the main board?

@jens55 I confirm there is an issue. I have a delta with one extruder and a bed heater, and Turn Everything Off works as expected. I also have a tool changer, on which 2 of the 4 tools use tool boards; but on that machine Turn Everything Off does nothing. All boards running RRF 3.4.4. I will investigate and report back.

@dc42,
THANK YOU THANK YOU THANK YOU !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I am soooo glad I am not going insane !

@jens55 We have identified the problem and it will be fixed in the upcoming V3.4.5.

jens55

@chrishamm, great news, thank you !

@jens55 FYI it's related to how many tool heaters the machine has. The length of the commands that DWC sent to turn the heaters off was too long to fit in the HTTP input buffer, and RRF was not returning an error code when this happened. We have fixed both.

jens55

@dc42 , cool, thanks for that extra info!
