5. Calibrate the Z Axis Offset
When the Extruder is at the home position of Z Axis, we need to make sure that the
distance between the nozzle and print bed is close to zero, no more, no less, in order to
make the print model attached to the print bed well.
If the nozzle is too high, the model will not stick well on the print bed.
If the nozzle is too low, the filament can’t come out smoothly and it will even damage the
print bed.
