How the System Responds to Needle Z Detect or Needle XY Adjust
NOTE:
On systems with the optional tip detector or tip aligner, both the Needle XY Adjust and Needle Z Detect
buttons are present. On systems without these devices, 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 confirmation 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 fluid.
• Moves the camera over the deposited dot of fluid.
• Compares the alignment of the dot with the mark image saved in the Mark Library.
• Requests confirmation for any change in the camera-to-tip offset (XY offsets).
• Realigns all points in the currently open program to the new XY offsets.
