I used to just mod the basic 5 materials and save as a new name after endless tweaking till I got a material (filament) dialed in well. However, in v5x I expected there to be more choices by default. Am I missing something? I tried adding different printers just to see if some materials would show up for different printers (like with other slicers), but I just see a default 5 materials (PLA, ABS, PETG, PVA and Nylon). Is that correct?
Yes, we usually provide several different stock materials and then you can add a new material if needed by clicking the "..." button beside the material options and choosing "Add new Material option".
