14.3.7.1. Fix Camera Scale Calibration

The fix camera calibration must be performed before performing fiducial camera offset

calibration.

First, teach the fiducial mark on the upper surface of the fix camera and perform

calibration of the fix camera scale using the CNT20 nozzle.

 <5. Fix 1 Camera> button

This calibration is performed to calibrate the Scale (um/pixel), Rotation (deg) and

Position (mm) of the fix-camera.

In order to perform this calibration first, the R-Offset Calibration must be performed in

advance and the calibration-nozzle must be used. Use Hole #1 as the ANC hole

exclusively used for the calibration-nozzle.

The following is the procedure to calibrate the Fix Camera Scale;

1. If the <5. Fix1 Camera> button is clicked, the message “First, We must Put all Nozzles

From Heads on Manually. To Move down Z Axis, Click [Next]” appears in the

message box. Click the <Next> button to move down the Z axis of the head in order to

manually move all nozzles inserted in the nozzle holder of the head.
