Thank u so much. It resolved my problem
I just had the very same issue, thats how I found this forum. For me, I noticed that different models allowed different filaments. To solve this, I made sure my filaments were configured in the “Project Filament” on the left in the model I want to print. Then under “Process” I select the object, find it under the list and right click, down near the bottom is a “change filament” I can then change the default filament to what I want.
Not sure if this is the best process as it’s time consuming for each and every model I print.
I wonder if there is a way to set Bambu Studio to always default to my loaded filaments rather than those saved in the object file?
I had the exact same issue and after 30 minutes of googling this comment saved the day thank you so much!!!
