I really find the new H2D specific features in Bambu studio not very intuitive. Is there any documentation on them? I haven’t found any.
When you just have a single material print, I don’t understand why you must change filament grouping settings to manually choose a nozzle, and then select compatible filament specific to that nozzle. Why can’t you just choose from a full list of compatible filaments?
Could you please provide more context for the questions you have? It is already possible to select a nozzle, then select the type of filament to use, which are compatible with the nozzle.
Have you tried the H2D Academy Course and the Bambu Studio Academy Course?
They might offer you more information and help you get the most out of your printer.
