4.7 Lubricating the Cables and Linear Guides
The X-, Y-, and Z-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 4-5.

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.

the grease.
