Fig. 6.3 Lubrication and Maintenance of X/Y Axis Linear Guide Rails
The Z-axis motion components include linear bearing and ball screw. It is recommended to re-apply
Perfluoropolyether grease or lithium soap based grease to the Z-axis motion components once every
6 months (The rear plates of the printer shall be removed).
1. Power off the printer and unplug the main power cord.
2. Remove the 4 locking screws at four corners of the rear cover with a wrench.
3. Apply Perfluoropolyether grease or lithium soap based grease to the linear guide rail and
ball screw with a soft brush. Excessive grease may have a negative impact on motion.
4. Install the rear cover back to its original position and fix it, plug in the main power cord,
then turn on the printer, and move the Z-axis up and down 10 times to evenly smear the
grease.
