Machine zero point: 10
– The PCB-camera center is the reference at the gantry. All positions at the incremental encoder
of X/Y-axis refer to this camera center.
– A drilling is optically centered with the PCB-camera on a defined position at the calibration tool
support.
– Than the Zero point correction of the gantry axes are changed that if the PCB camera is above
this hole and the Positioncounter shows exactly the value of:
MA nullpunkt_x_PG1 631300 / MA nullpunkt_y_PG1 1298000. ( pg means gantry group)
MA nullpunkt_x_PG2 1368700 / MA nullpunkt_y_PG2 702000 ( See Fig. 10.2 - 2)
PCB camera: 10
– the Pixel size of the CCD sensors of the camera is determined in µm. Measured and calcu-
lated with Ax/Bx/Ay/By calibration values. Saved in KAM_DAT.MA as:XU_Pixel / YU_Pixel
(in 11600 nm Standard-PCB camera SST 5), (in 9900 nm Multicolorillum. PCB camera SST 18)
– The camera center is determined.
– This camera center is now the reference for all Position and Offsets of the gantry!!
– The Mounting angle of the CCD-chip in the camera to the Ma-coordinate system. Saved as
‘Kamera_winkel’ at the Data bloc of the PCB camera in KAMDAT.MA.
Calibration tool position:(optional) 10
– Calibrate the X and Y pick up position of the calibration tool.
Travel range:(optional) 10
– For travel range calibration move the respective axis: -to the Zero-pulse
– Then to the Hardware-limit switch
– Measure the position value at the position counter
– Calculate the position for SW-limit switch (Y +/- 1.5 mm , X +/- 0,5 mm)
