12.4.2 Zero Point Offset
The machine zero point (measurement point for each gantry) serves as the reference point for the X and
Y axes to the machine coordinate system. This means that both axes know exactly where they are in the
machine.
This machine point (fiducial) is approached with the help of the PCB camera and is measured in the X
and Y direction. The resulting offset is added to the fixed zero point correction value for the X and Y axis.

12.4.3 PCB Camera
Determining the calibration factors, relation of camera pixel size to resolution of machine
measurement system (X, Y).
The camera center point is determined in the X and Y directions.
Determining the rotation angle of the CCD sensor in the PCB camera.
The evaluation of the maximum and minimum
travel range for machines with A364 is
performed via the hardware bumpers. These
values are required for monitoring the travel
range, the speed and the gantry.
The X axis moves to the left and right bumper
and measures their positions with a safety
distance of 2.0 mm. A safety distance of
0.5 mm is also taken into account by the
software.
The Y axis moves to its minimum position
(gantry 1/2) or maximum position (gantry 3/4).
