I’m switching from a 0.4mm SS nozzle to 0.4mm hardened steel. Do I need to recalibrate flow rate and K factor for my filaments? What about if I go to a 0.6mm nozzle
There might be a slight change in the PA (K) Value if you change between SS and Hardened steel within the same nozzle diameter. Change of Nozzle diameter will have a bigger effect on the PA compensation.
