consider the factor you’ve changed and how it could affect the calibration, swapping the plate probably wont affect what’s coming out of the nozzle, swapping the nozzle for a new one of the same size will though. however you might want to consider bed temps, starting temps and first layer cooling etc.
As for a general question from me, has anyone figured out a way to get feedback from the printer regarding the values of the dynamic flow calibration? I realize that theyre variable and that they’d change as soon as you change nozzle temp but if you could get that info back you’d probably be able to adjust the two calibration passes to be faster.
