How to get the idle cooldown to work?

[FlashErase]

Hi,
I want to use S3D for my Snapmaker J1S printer. Normally it works fine but I was not able till now to get the idle cooldown function to work in two color print. I placed my settings and the resulting gcode here: https://www.dropbox.com/scl/fo/7sgl7m6s ... uz3gg&dl=0
The Sequence "S150" for the cooldown temperature is to find only 27 times in the gcode for a model with 259 layers.
Is it really necessary to make the temperature settings for both extruders in both processes (means 4 different temperatures).
Hope you can give me a hint how to configure the temperature controllers for this project to get the idle cooldown to work.

I fixed it. Thanks!
