The filament is stored on a spool (right) in a plastic bag, as PLA absorbs moisture from the air and will become brittle and snap if it is not kept dry. The first step is to place the spool in the filament holder (left), and thread the end through the beginning of the filament tube (on the bottom left of the filament holder). Push it through enough that it will stay in there, but not enough that it is sticking out the end of the tube (on the top left of the filament holder)

Once the filament is loaded into the filament holder, close the holder. Open the front door of the printer, and slide the filament holder into the slot on the far right side with the same orientation as shown to the right.

On the printer itself, go to filament-> load filament and hit ok. This will load the filament into the whole system, and you will be ready to print!
