2.
Adjust Z-axis height and fine tune the knob on the camera.

When the photo in camera sight becomes enough clear, click

. The
system records the current height.
It proves that when the magnification factor sets to 15X, the camera
gets the best adjusting result. In this case, working distance needs to
be within 120mm~130mm.
Once the working plane is set, it will be the height for Z-axis in the processes of
measuring magnification factor, CCD-spindle offset, picking template and shooting.
In addition, the height is independent to workpiece coordinate system.
Setting CCD Magnification Factor
Image takes pixel as unit, but machine moves in millimeter. Therefore, the
relationship between the pixel and millimeter is the magnification factor.
Characteristic point on the workpiece is used to decide the magnification factor.
