Ultimaker 3 Extended Maintenance

Hot pull
1.
Insert the filament into the print head until you feel some resistance
2.
Hold the filament with pliers and gently apply pressure to the material for ±1 second
so that it extrudes from the print core or until it cannot be pushed any further, and
directly pull the filament out with a quick, firm pull
3.
Cut off the tip of the filament that you have just pulled out.
4.
Check the color and the shape of the tip of the filament and compare it with the
image below. The goal is to have a clean tip
5.
Repeat this procedure until there is no more degraded material visible on the tip of
the cleaning filament. The tip of the filament should look as clean as the example
below
Caution:
Use pliers to prevent injuries to your hands in case the material breaks.
Caution:
Do not use a needle to unclog the CC print core. If the point of needle
touches the ruby, this can irreparably damage it.
