The following procedure is often referred to as an Atomic (or Cold) pull. This is a useful procedure when you want to clean or unclog a nozzle.
We recommend performing an atomic pull once or twice a month for optimal performance.
Always check that you're printing using the right temperature for your filament and that the Capricorn tubing is not entangled or twisted, causing unwanted friction before attempting to unclog a clogged nozzle.
- Heat up the Hotend to the recommended filament temperature.
- Lift the lever on the extruder while manually pushing the filament through till you know that the filament has reached the nozzle.
- Turn off the Hotend in the manual controls (Settings » Extras » Manual controls) and wait for it to cool down a bit.
- When the Hotend reaches 80°C for PLA or 120°C for ABS (see indicator on-screen) push the Titan lever up once again and give the filament a quick pull.
- Inspect the end of the filament for signs of carbon particles.
- Repeat the whole process again until the filament you've pulled out is clean from debris.
- When the filament is clean, heat up the Hotend once more and use the unclogging needled provided in your supplied toolbox. Also, use the tweezers to clean the outside of the nozzle.
