I’m afraid there’s an issue with the translation software. I can’t find the function you mentioned in Cura either. The name displayed to me in German is likely a fanciful creation by the AI.
I found it. There are two methods: either as a cut or as a modifier. I’ve now placed two modifier cubes at the two critical points and reduced the speed there from 200mm to 50. The test will only run once the print bed is free.
So thanks!
I have now found the solution to my interface issues:
Interfaces with 2 layers on top/bottom, smoothed, and 0.0 Z-distance.
Changed PETG from Generic-PETG (16mm³/s) to 270°C for both model and supports.
Reduced the model base on the supports via Modifier to 30mm/s.
Changed PLA from Generic-PLA to 6mm³/s (probably unnecessary, since the interface is already at 50mm/s) and 250°C.
Now, small interfaces hold on the supports, and the PETG holds on the interfaces.
Gray is the PLA, and on top of it are two ~1cm long black strips of the object. This should be the transition to full speed.
The same with only one layer of the object
Copy & paste it.
