6. If the calibration procedure is completed properly, the result as shown in the following
figure is displayed and then the message, “Move (Fiducial/Teach) Camera Offset is
Finished. Remove Tool Plate!” appears. At this point, remove the flat board calibration
tool placed on the Fix 1 Camera. Otherwise, damages may be caused by collision with
the head.
Memo The reference values for the calibration of the Camera Offset is as
follows.
Camera Offset (FOV 12)
Offset X : -76.0mm ~ -74.0mm
Offset Y : 54.0mm ~ -56.0mm
14.3.7.4. Head Z / R Offset Calibration
The distance from the upper surface of the PCB to the Z axis home is set mechanically. For
the Z offset calibration, measure the offset for this distance based on the upper surface of
the PCB by using pneumatic pressure.
For the R offset calibration, measure the offset of the angle to align the nozzle holder
based on zero (0) degrees.
The following is the process that the Z offset calibration is performed. The nozzle used for
calibration is the CN040 nozzle.
1. Click the <Head Z / R Axis Offset> button.
2. Click the <Nozzle Prepare> button and remove all nozzles inserted in the nozzle
holders of all heads. Insert the CN040 nozzle into the No. 14 hole of the ANC.

Machine Calibration
Since the position at which the Z offset is measured deviates from the calibration tool
position (center) by 3mm, if any foreign material on the calibration tool is present,
remove it.
3. In the <Grid> group, select the Z axis for which the calibration is to be performed and
click the <Detect Z Offset> button after selecting the <Automatic> check box.
4. Click the <Next> button.
5. The head moves to the designated position on the ANC automatically. Then the
machine creates pneumatic pressure and performs calibration while moving the
spindle down from Head 1 to Head 6 in order.
6. If the calibration is completed, the calibration result is reflected on the Z column of the
<Grid> group automatically.

7. Press <Update> button to apply the calibration result to the machine
Memo The reference values for the Z-offset are as follows.
Head1~ Head6 : -1.5 ~ 1.5 mm
If the Z offset value exceeds this range, it means that the head has a
serious problem. Therefore, check for the home location, spindle,
LM, and verify if the motor operates normally.
The following is the procedure to perform the ‘R-Offset Calibration’.
1. In the <Grid> area, input “0” for all R-axis values of the heads for which the
calibration is to be performed.
2. In the <Grid> group, select the R-axis for which the calibration is to be performed and
click the <Nozzle Holder Check> button. (Set value to head 1 by arbitrarily.)
3. Then a message reading, “First, We must Put all Nozzles from Heads manually. To
Moving Down Z Axis, Click [Next].” will be displayed in the message box. Click the
<Next> button to manually remove the nozzles attached to all heads.
At this time, for the ANC, the virtual nozzle CNT0 is set for the No. 1 hole of the ANC
and it is regarded that the corresponding head picked the CNT0 nozzle.
