When obtained the platform height
value of all 9 positions. Find out the
smallest value among the 9 calibration
points.
As you can see in this case, the
calibration point 1 has the smallest
platform height value, it is actully the
highest point on the platform. Therefore
the platform does not need to rise as
high as the other points to reach the
nozzle

We set this mimimum platform height as
"Nozzle Height" since it is where the nozzle
first start to touch the platform. Now go to
calibration point 1 and rise platform to 208.
Click the button" Set Nozzle Height" to
finish.

2. Setting Compensation Values
Afte setting the nozzle height, the drop down menu next to the
buttons will be available. A compensation value between 0 - 1.0 mm
will be available for selection.
To calculate compensation value:
Platform height - Nozzle Height = Compensation Value
Platform Values at 9 calibration points (hypothetical):
1: 208 2: 208.5
4: 208.6 5: 208.9
7: 208.8 8: 208.9
As shown in the left, when platform is
at the "nozzle height", only part of the
platform is close enough to the nozzle.
Therefore we need to set compensation
values for all other calibration points to
inform the printer about the distance
between nozzle and print sur face
throughout the XY plane.
