The Z-axis cover is mainly responsible for protecting the Z-axis screw and other components of the printer’s drive system. It also prevents these components from becoming dirty during the printing process and from being reached while the printer is running. The cover is divided into three individual parts that are secured in the printer.

You can easily remove the cover to access the Z-axis screw, X/Y axis motors, or short belts for maintenance or repairs. Also, once the cover in your printer becomes worn and dirty, you can replace it with a new one. This manual shows the removal of one part of the cover, the other two parts are replaced in the same way.
