3.02 What is a PNC Calibration?
•
In order to get precise PNC results, you must calibrate the camera. This is nothing more than letting the
Skycut know how far away the camera lens is located relative to the tip of the blade. Because the camera is
manually installed inside the blade carriage, the distance from the camera’s center to the tip of the blade will
vary from one Skycut to the next.
•
This calibration only needs to be done one time. If you have travelled with your Skycut or it’s been bumped
fairly hard, you might want to run a test to make sure your calibration hasn’t changed. It’s also
recommended that you check your calibration after any firmware updates are installed.
•
The process, which is conducted through the control panel involves:
(1) Having the Skycut draw a test shape. At that point the camera takes a photo and displays it on the
control panel, along with a
red
+
and a large
blue dashed
+
.
(2) Aligning the
red
+
with the center of the test shape display several times until the
blue dashed
+
is
centered with the test shape.
3.03 Camera Calibration Procedure
3.03.1 What You Need for Calibrating
•
You need the following items for this calibration:
Sheet of paper
Test pen that came with your Skycut
3.03.2 Calibration Process
(1) Insert the test pen into the Skycut. Place the sheet of paper into the Skycut. You can use the cutting mat to
hold the paper or insert the paper directly.
(2) On the control panel, move the test pen over the sheet of paper.
(3) Select
Speed/Force
and set
SPEED
to ~ 8 and
FORCE
to ~ 30. Click on
Test
to verify that a square is
clearly drawn. If it is too faint, increase
FORCE
as needed and repeat.
(4) Move the pen an inch or two away from the test so that there is room for the calibration shape to be drawn.
(5) On the
Main Screen,
press
Set
and then
Camera
:
A custom shape is cut
around the printed image.
