M600 - prevent power cut of motors

[tak21]

I want to use M600 in my slicer to make color changes with a single extruder.
It works flawless - if I am fast enough / close enough to the printer to do the change before "something" shuts down the motors and cuts the temperatures.

What I do not know (and do not find information about) is this "something".
What script / service / ... is shutting down the heaters and motors after some time if "nothing happens"?
Can I change the behaviour? (E.g. motor shut down: NOOOO, bed shutdown: please not, extruder shutdown: yes).

Thank you in advance!

@tak21 Sounds like you have a motor idle current factor configured, try to set it to 100% in your config. See M906 I.

@tak21 idle current reduction will reduce current to the motor after 30 seconds by default. However, if the heaters are shutting down, that must be something else. Does your filament-change.g file if you have one, or your pause.g file if you don't, turn heaters off?

Can you share your config.g and pause.g or filament-change.g file? Can you also share your firmware version?

@all: From your reactions I assume, that this is not a standard behaviour. As I used - as a base a configuration - a Caribou3d 320 config including macros I will now search for a macro / service which is not comming ootb and triggers this behaviour.

Question please: if I would want to implement a "shut down the heaters if nothing happens for some time", where would I start to implement it?

[tak21]

@chrishamm I think I did not configure this as the documentation says: do not use it.

In daemon.g

@dc42 Thank you! I found it
