// Z Axis 3200, / 8mm pitch leadscrew = 200*16 /8 = 400 :: (STEPS_PER_REVOLUTION_Z / PITCH_OF_Z_ROD) // Z Axis 3200, / 2mm pitch leadscrew = 200*16 /2 = 1600 :: (STEPS_PER_REVOLUTION_Z / PITCH_OF_Z_ROD)It also means the Z-Axis stepper motors will have to work less to lift the Z-Axis load.

It will give enough torque to straighten any crooked frame and overcome stubborn guides A must for most hobby 3D printer.
A good machine will prefer an 8mm pitch.
