Placing the spool with filament
After bed leveling it’s time to further prepare the Ultimaker 2 Extended+ for the printing by loading the filament.
Place the spool with the filament on the spool holder. Make sure to put it with the filament in counter-clockwise direction, so that the filament can enter the feeder from the bottom. Straighten the filament a bit so it can easily enter the feeder. Next, wait a minute while the print head heats up. Heating up ensures that the filament melts when it goes through the nozzle.
Caution: Ensure that you don’t touch the nozzle during this procedure as it will become hot.
Loading the filament
Insert the end of the filament into the bottom of the feeder and push it until the filament is grabbed by the feeder. Wait until the filament appears in the bowden tube and then press the button to continue. The Ultimaker 2 Extended+ will automatically load the filament through the bowden tube, into the print head. Now you just have to wait until the filament comes out of the nozzle.
Note: Don’t be surprised if the filament that initially comes out of the nozzle is not the color you expect. There is probably some residue from the test print left in the nozzle. Wait until you see the color of the filament that you loaded coming out of the nozzle.
