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 usually print a calibration square at whatever the filament’s recommended nozzle/bed temperatures are. From that I will fine tune the extrusion multiplier until it’s a perfect first layer. I prefer to do this instead of adjusting the Z offset for each filament.
This seems to keep my nozzle cleaner and my prints looking better because the nozzle doesn’t drag through printed lines or drop buildup in a random place. Printing the square only takes 11 minutes, so it’s worth the time.
