Hi I have a P1S (new to bambu) and 2 AMS units. I downloaded an STL off of thingaverse and would like to print it in PETG which is loaded in my AMS and is configured (color, brand, filament type) under device settings. When I go to print the plate it gives me the select popup but the PETG is gray…

Have you assigned the PETG in the ‘Prepare’ tab? If not, right click on the model and scroll down to ‘change filament’ and select the PETG.
