Adjust the Z-offset by turning the knob
counter-clockwise to raise the value, or clockwise to
lower it. The Z-offset is a negative number, with zero
being identified as the top of the heat bed washers.
A larger negative Z-axis value brings the hot end nozzle
closer to the print surface. A smaller negative Z-axis
value will move the nozzle further away from the print
surface.
When you have adjusted or restored your Z-offset,
select Store Settings from the Configuration menu
to save it. You will hear a beep, indicating that the
settings have been successfully saved.
