Mixture always wrong

[nicoch]

I use Cura 4.5.0 on Mac and I configure the model to be printed by the first extruder.
But all the time the "Mix" Settings are overwritten by the printer. I used the reset button but nothing changed.

If I toggle the mixture to 100,0,0 before printing it always jumps to 59;19;22 and I have to manually set to 100,0,0 as fast as I can, to get the first layer right.

So the question:

Are the settings overwritten by my printer (is there an option to not overwrite anything?) or can I change something in Cura to get the Mixture right ?

Thanks !!

Hi, you can check your start gcode.
If there is M 163
M164's color mixing instruction can delete it.
