3. Press the control wheel again, and the extruder will move onto the second
calibration point. Repeat the previous process, then do the same again for the
third calibration point.
4. Finally, the extruder will move across to the centre of the base, and you will
be asked to verify the distance between the nozzle and the print base once
again. Once you have done so, press the wheel to exit the levelling program.
It is recommended that you repeat the levelling process as many times as
necessary, in order to make sure the base is correctly levelled.
