Steps permm of filament settings
The EEPROM of my p802e Tronxy says extr .1 is 90 steps per mm. the motor moves 1.8 deg per step so 90 steps equals 162+ deg which translates to 7.9 mm when measuring the diameter of the drive gear. I'm up grading from remote extruder to a geared direct extruder and a reprap smart display. how do i figure the steps i need for the new extruder.
