Dual Extruder Snapmaker breakaway nozzle clogged

Hello,
I have problems printing with the second nozzle of the dual extruder.
I use the nozzle for the Snapmaker Breakaway filament. I have currently set up Cura so that only the interfaces (roof and floor) are printed with the filament to save costs. It works great for small projects. I have major difficulties with larger projects because the nozzle then becomes completely clogged and the filament then burns? It will be brown.

I print it at 225°C.

It happens that my settings for standby and the retraction when changing nozzles are not optimal.

Can someone give me some tips and settings for Cura for the filament?
