I’m trying to add eSun filaments to the Filament Manager but the only type it allows me to add is PLA+. I know I could add other types as generic but I’d really like to see them listed as eSun, so I can readily see what I have. Is there a way to get Filament Manager to do what I want? For that matter, is there a way to make Filament Manager actually uselful with Bambu Studio? It won’t even track my filament usage when using the AMS Lite and I can’t see how I can readily populate the external spool holder with a filament from the Filament Manager. Quite frankly, at this point I’m starting to wonder why I’m bothering with it at all, as it seems like it’s a framework for a good idea but has yet to be implemented beyond the most elementary level.
I have similar problems with the presets, and I have decided to just give up on them and add some random ones other people made (there are a couple of them on makerworld I believe), at least that what I tried when I printed TPU for the first time in an attempt to improve print quality. Now I can set that profile as a preset, so yeah, it’s really annoying but 
It’s the same for me. I can’t use manually added filaments—or rather, they aren’t being accepted.
I decided to just give up and created my own filament inventory system. It’s web based, running on my own server, so that I can access it from anywhere. It obviously won’t automatically track usage but it’s very much simpler to use than the one in Bambu Studio. e.g. After a print I can just type a negative number into a filament’s weight column to subtract that amount. I’d be happy to share it but as it’s designed very specifically for my server setup it’s not easily transplanted.
