coordinate X1 and Y1 ,X-X1=A ;Y-Y1=B.
If A is positive and B is positive, the sensor is positioned on the right_up side of
the laser head
If A is positive and B is negative, the sensor is positioned on the right_down side
of the laser head
If A is negative and B is positive, the sensor is positioned on the left_up side of
the laser head
If A is negative and B is negative, the sensor is positioned on the left_down side
of the laser head
In the laser cutting software menu click position sensor calibration, according to
the calculation value position; and the corresponding A and B values to fill the X
sensor offset and offset Y; here we only fill in the absolute numerical results, and the
implementation of the "confirm" closed "position sensor calibration interface.
