As i understand it can be found on the printer screen not in Bambu Studio. I think this allocation is permanent whenever the right filament and the right nozzle are installed.
Or if you mean on the printer itself, you have to start a print, then the “Next” button, and on that page you can select a hotend/filament using the “Right extruder” icon/button.
Found it. But i fear its only for the actual print file. I thought that i can combine a filament (i.e. TPU for AMS) with a nozzle (i.e. 0,6mm) so whenever i print with this filament the correct nozzle is automatically chosen.
Ah, yeah, that’s on the wishlist for many users, especially given as how the advertising strongly hinted at that feature. But as far as I’ve seen or read so far, there’s no way to make the filament ↔ hotend mappings “stick” beyond the current print session. And for “special” hotends, like for TPU or CF material, it’s still a manual process of keeping track because at this point there’s no way to tell which actual material was last used in a nozzle, besides the color (sorta). Not useful when all your “engineering” filaments are black.
