Filament change during print on Sermoon V1 Pro

Hello printfriends, I need your help. I try to do a filament change during the print and can’t find a working solution. I’m using the Cura slicer but had the same problem also with other slicers, such as Creality Print, Prusa Slicer, etc. On Cura, I use the pause at height script and change it to layer number. I tried Marlin (M0), BQ (M25), etc., but nothing works. Sometimes the printer doesn’t even stop, with other settings it stops and the head moves to the park position. But when it’s parked, I can’t change the filament or do anything else except stop the whole print by pressing stop. Sometimes the screen freezes, and I have to switch off the printer.

Does anyone have step-by-step instructions for me on how I can pause my Sermoon V1 Pro at a specific layer height to change filament and restart the print?
