Rods lubrication
It is recommended to grease the rods from time to time, especially when they suffer from difficulties moving or make
more noise than usual. Place a few drops on the rods, and move the axes so that the same mechanism distributes

Filament spools should be stored in a cool, dry place, heat and humidity affecting this kind of plastic. If a coil is not to be
used for a long period of time, store it in a sealed plastic bag.
Ensure that the filament is neatly coiled. A loose coil can cause it to curl wrong, and cause jerks affecting printing and the
machine components.
