To adjust the distance between the probe and the needle:
CAUTION! Only an Asymtek-trained service technician should perform this procedure.
1. Using the Z-axis controls, raise the Dispensing Head so that neither the needle tip nor the probe
tip is touching the work surface.
2. Install the needle you will use.
3. Make sure the probe is in the GD position.
4. Using the 1/16-inch hex key, loosen the probe set screw accessed through the hole on the right
side of the Height Sensor (see Figure 10-3).
5. Move the probe to the new distance from the needle.
> The recommended distance between the needle tip and the probe is about 1 mm (0.04 in)
(Figure 10-5).
6. After adjusting the probe position, tighten the probe set screw.
7. Run the
Height Sensor Setup procedure on page 10-7.
