If you want to switch between different (colors of) materials, you first need to unload the filament that is already in the Ultimaker 2 Extended+, after which you can insert the new filament.
Removing old filament
Removing the filament can simply be done by following the steps below.
Go to “Material” > “Change” in the main menu.
Wait a moment while the print head is heating up. Heating up the print head ensures that the filament melts when it goes through the nozzle.
When the nozzle is hot, the Ultimaker 2 Extended+ will automatically start turning the feeder wheel, through which the filament will be rewind completely. If the filament doesn’t come out of the feeder completely, you can pull it out by hand.
Loading new filament
After removing the filament you can start loading the new filament in the same way as done during the first use of your Ultimaker 2 Extended+. Make sure the old spool of filament is removed and the new one is placed on the spool holder with the filament in counter-clockwise direction.
1. Insert the end of the filament into the bottom of the feeder and push it until the filament is grabbed by the feeder.
2. Wait until the filament reaches the first black bowden tube clip and then press the button to continue. The Ultimaker 2 Extended+ will automatically load the filament through the bowden tube, into the print head.
3. Press the button at the front once the filament comes out of the nozzle
