ONLY SYSTEMS WITH A TIP DETECTOR:
• Click NEEDLE Z DETECT to test the setup.
• Click YES/OK when prompted for conrmations.
NOTES:
- When the system performs a Needle Z Detect, it automatically performs a
Needle XY Adjust directly after performing the Needle Z Detect.
- Refer to “How the System Responds to Needle Z Detect or Needle XY
Adjust” on page 44 for a detailed description of the system response to
a Needle Z Detect selection.

SYSTEMS WITHOUT A TIP DETECTOR:
• Click NEEDLE XY ADJUST to test the setup.
• Click YES/OK when prompted for conrmations.
Refer to “How the System Responds to Needle Z Detect or Needle XY
Adjust” on page 44 for a detailed description of the system response to a
Needle XY Adjust selection.
The system is now properly set up and calibrated. Refer to “Programming” on
page 48 to create programs.
How the System Responds to Needle Z Detect or Needle XY Adjust
NOTE: On systems with the optional tip detector, both the Needle XY Adjust and Needle Z Detect buttons are
present. On systems without the optional tip detector, only the Needle XY Adjust button is present.
When you click NEEDLE Z DETECT, the system performs the following actions:
• Moves the dispensing tip over the Tip Detector sensor and lowers it until it touches the sensor.
• Measures and compares the difference between the last measurement and the current measurement.
• Requests conrmation for any change in the tip-to-workpiece offset (Z clearance).
• Realigns all points in the currently open program to the new tip-to-workpiece offset (Z clearance).
• Automatically performs a Needle XY Adjust sequence (shown below).
When you click NEEDLE XY ADJUST, the system performs the following actions:
• Moves the dispensing tip to a preset location on the workpiece.
• Dispenses a dot of uid.
• Moves the camera over the deposited dot of uid.
• Compares the alignment of the dot with the mark image saved in the Mark Library.
• Requests conrmation for any change in the camera-to-tip offset (XY offsets).
• Realigns all points in the currently open program to the new XY offsets.
