Confusion re DWC 'control heaters'

[Phaedrux]

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?

[dc42]

@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 !

[dc42]

@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.

@dc42 , cool, thanks for that extra info!
