Command to turn heaters active/standby/off?

Got it - thanks.

And I am currently doing as suggested G10 P0 S-999 R-999 which is a bit non-intuitive but it works.

@fcwilt may I ask why you need to turn off (as opposed to set to zero) tools?

It's just the way my mind works.

In my home I can set the mode (off, heat, cool, auto) of the thermostats independently of the heat/cool set points.

Sort of, vaguely, in a round about way, kind of the same thing.

Finally, someone other than me that thinks having the ability to control heater states independent of tools or temperature is a good thing.

I've brought this up several times over the past few years but it never goes anywhere or the response is "Let's talk about it with the next release". I guess it's time for me to start pushing it again.

My examples were to do preheating of tools before use, ease of toggling bed and chamber heaters without mucking with the temps, being able to testing and tune during printer construction, etc.

Well to me it makes perfect sense since they are independent properties.

As it is, as shown, I have to set both temps to a large negative number before the heater will turn off.

@fcwilt Exactly.

I'll make another run at @dc42 with my latest patch that adds that capability.

@gtj0 I'd vote for this too!

It may be more of a DWC thing, but I run a chimera. If I set a print going using only one nozzle, I'd still like to be able to manually set the unused too standby in some cases (e.g. because I notice it's hitting the print), when it would usually just be off. I've not yet found a way to put a tool into standby without affecting the active tool (which is not ideal if that tool is printing!)

Another use case I can think of would be manually changing filaments in a docked tool on a tool changer

We already have plans for this, which I originally hoped to include in 3.2 but we ran out of time, so it will be in 3.3.

I have added a comment th the PR from @gtj0.

Hi,
juast asking as an end-user:
As far as I understood your "pull-request", it could be that my usecase could already be implemented by your suggested changes, but: Since e.g. within M144 the letter "S" is used, would it make sense to use that also for your suggestions, I have seen "A" is proposed? Or to keep things consistent change M144 "S" also to "A" for state? Or is M144 on the long run going to be depracted?

all the best

One use case that I would need it for would be a pause in printing.
Since you are not always on site I would like to switch off T0 and T1, but without changing or losing the set active and standby temperature.
So that when you continue printing, the correct temperatures are available without having to make this setting.

hey, sorry if i'm creating a double, but does the feature been added ?
i've checked changelogs and Gcode dictionary, but i havn't find the answer.
If it's added what's M or G code it is ?

@kenny_mc_cormick it's added in 3.3RC2 which is soon to be released.

@dc42 awsome !! can't wait to have it !
you guys doing such a good job !

edit:
@Phaedrux i check that. I guess it's "M568 P2 A1 ; set tool 2 heaters to their standby temperatures" to use, but does it set the tool on standby or does it just turn the heating on ?

It turns the heaters on too.
