Lubricating the Cables and Linear Guides

The XYZ-Axes support the Dispensing Head and allow it to travel within the dispensing area. To ensure

smooth Dispensing Head movement, the rails and linear guides must be lubricated approximately every

three months. The location of the Mechanical Drive Cables is shown in Figure 5-3.

Lubricating the XYZ-Axis Cables

1. Remove the X and Y axis covers as described above.

2. Move each axis to its home position. (X-axis far left, Y-axis rear, Z-axis upward)

3. Using a new lint-free cloth, wipe all cables to remove old grease or contamination.

4. Move each axis to its opposite end of travel and continue to wipe the cables clean.

5. Apply a light film of cable grease to all cables.

6. Move each axis back and forth over its entire length of travel four times to distribute

the grease.

7. Wipe off any excess grease.

8. When finished, replace the axis covers and tighten the screws.

" NOTE When replacing the X-axis cover, make sure to place it on the spring pins.
