M144 opt. H parameter (default=0) for single-extr. printers

I don't understand the use case either. Why don't you want to deselect the tool when you put it into standby?

Thanks for the fast reply!

I guess you could call it lazyness or philosophical:
The concept of tools might be really needed if one would have more then one tool. With single-heatplate single-extruder printers, I just ask myself, why I cannot avoid everything related to "tools"?

With that optional H paramter within M144 I think I could throw out all tool-related stuff everywhere, but in the config.g, where it simply selects the one and only tool 0 in the end of it, and that´s it. -> Would only need tools on those printers that have more then one

(hm - I know I know - a lot of ideas that I post here - )

Is there any other way to call via command-line the extruderheater (H1) to standby without having to deselect the whole tool?

Edit: I have always asked myself what is DWC sending to the mainboard when I click on the picture to toggle through the states to go from "active" to "standby" (and finally "off" until it starts again)

?

Edit-edit: To put it straight, by my firmware-wish, I could get rid of all tool-related macros like "tfree0.g","tpost0.g" & "tpre0.g"

Maybe you close this. This is maybe too far off.

I just cannot wrap my head around why I can toggle between "active" & "standby" for the heatplate but do not find any information to do the same for the tool (without de-/selecting it)

I think I rather go to sleep now -> Next morning the world might look better already

It's the generalized nature of RRF that gives it its power and flexibility.

Thanks! Yep, guess there is some truth in that statement.
Could you please close this post -> Will open a new "help" post in the "general" field to see how far it get´s me
Also my intent was to get things "simpler", having more and more option is a difficult way to contribute to the KeepItSimple-principle. Too many new stuff: Variables, conditions Guess next should be to contribute to the documentation of all that

I thought about it and I guess I settled with the idea that for the single-extruder I will be fine by just setting the active temp from 0 to whatsneeded and just ignore to use standby (or do I just do not get how to access standby-temperature without de-/selecting a tool?)

Phaedrux

standby is still useful in a single tool printer. like lowering the temp on pause.

Thanks for replying.

I just do not get what is the G-/M-code for doing it (not using DWC or PanelDue)?

Ah, but then I am again back fiddling with Tools, which I wanted to avoid to fiddle with as long as the printer is single-extruder. Thanks anyway. I guess currently there is no way to toggle between active/standby temps without using Tools. Thanks so much for tryin to help me here! There are other things more important -> let´s close this post. I do not wanna "euch auf den Keks gehen" as we say in Deutsch (guess it translates to something like: I do not wanna walk over your cookies or so if that makes any sense)

The paradigm is tools. That's just the basis of how it all works.

Not sure why it's such a hang up though.

If Tn is used to select tool n but that tool is already active, the command does nothing. Otherwise, the sequence followed is:

If another tool is already selected and all axes have been homed, run macro tfree#.g where # is the number of that tool
If another tool is already selected, deselect it and set its heaters to their standby temperatures (as defined by the R parameter in the most recent G10 command for that tool)
If all axes have been homed, run macro tpre#.g where # is the number of the new tool
Set the new tool to its operating temperatures specified by the S parameter in the most recent G10 command for that tool
If all axes have been homed, run macro tpost#.g where # is the number of the new tool. Typically this file would contain at least a M116 command to wait for its temperatures to stabilise.
Apply any X, Y, Z offset for the new tool specified by G10
Use the new tool.

I get the sentiment.
