3.9 Adjusting the Height Sensor Probe
The height sensor probe must be adjusted each time a different type of dispensing valve or a different
length of needle is installed.
To adjust the height sensor probe:
1. Ensure that there is air pressure to the system.
2. Within FmXP, click on Tools, I/O Test, (Dispenser Icon) and select the tab for Outputs 0-31.
Click on the button that says “HS_PROBE_EXTEND” (this will extend the height sensor
probe).
3. The probe and a small setscrew will now be visible from the front of the Z-head.
4. Using a 1.5 mm hex key, loosen the height sensor probe locking screw at the back of the
Z-axis plate (Figure 3-10).
5. Move the probe to the desired location (approximately 10 mm below the needle tip in the
extended position).
6. Tighten the height sensor locking screw. Do not overtighten.
7. Click again on the "HS_PROBE_EXTEND" button to retract the probe.
