Only Polylite PLA shows up in my materials even though many others are in the folder. Can’t seem to add any to favorites, even though others say they have imported successfully
Material profiles have to match the machine_identifer, which is both printer model and toolhead specific, as well as filament diameter.
For example, here’s just part of the material profile for polylite pla 2.85mm:
So if you’re importing materials profiles from somewhere else, they probably don’t have the machine/toolhead combination. Or it’s the wrong diameter.
Material profile dependency hierarchies in both Cura and PrusaSlicer are kinda a mess to deal with.
