I see a lot of people claim they tune/calibrate their printer any time they use a new spool of filament. But does anyone actually do this? It feels like a waste of time when filament is so consistent, even between brands. I can understand doing it for specialty rolls, but for basic pla? Seems unnecessary
I calibrate flow rate for each filament, and looking at my SuperSlicer profiles I have values between 0.95 and 0.99 for PLA from different brands/product lines. I also have different temp settings for some, but that’s more a result of adjusting after prints than having actually calibrated it. I’ve been experimenting a lot though and have never bought the same filament twice but I would probably not recalibrate for a new spool of something I already have.
But if not calibrating works for you then there’s ofc. no point in doing it.
