I was hoping that the other makers having problems with fused hinges was just some mistake on their part, but I don't think that is the case anymore. I started with a filament that was decently tuned (and dried) and had fused hinges. I then tried my absolute tuned in print profile (I use this profile for a commercial design I sell) and still got fused hinges..
I don't doubt that the model prints perfectly for the creator, but I can say that with my tuned filament profiles I had fused hinges.
