the cleaning procedure

coupling collet while pulling the Bowden tube upwards, out of the print head. Select Confirm to continue
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
Use pliers to prevent injuries to your hands in case the material breaks.
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 on the right

out again. Select Confirm to continue
Cold 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 extrude some material. Select Confirm to continue
