I have recently only been trying to get together profiles also but I still not sure what I have done. I will make some up soon and make notes on what they are and then get some where I hope.

I wish I was just making quick changes on each print but I am starting to do a few quick changes but there are so many more things I am not sure of that could be changed.

I am only mainly changing Shell Thickness, Support Type, Platform - Raft, then clicking on Advanced but not doing much there yet, I see Preferences under File but have not changed anything there yet and I should be changing things under Expert/Open Expert Settings which there are things there I should be changing. Will I ever understand it all?

I recently bought some PETG filament which was all right but not as good as the PLA+ (PLA plus) which is the best filament that I have had success with. It is strong but flexible so I'll keep going with the PLA+.
