Coggled nozzle what to do
The nozzle is one of the most important components of the 3D printer. It is the piece from who the melted filament comes from.
Sometimes the nozzle coggle, consequently, the filament is no more able to pass through it. Nozzle cleaning can be helpful, but only if done correctly otherwise you can damage it irredeemably. In this post, we’ll see how to correctly clean the nozzle in the easiest and safest way. We’ll also see which are the more suitable tools and how to use them. Finally, you’ll find tips to prevent the nozzle coggling.
How to clean the nozzle
Firstly you must make sure that the nozzle is really coggled. To do that, heat the nozzle at the ordinary printing temperature and manually push hard the filament. If it blocks before to be extruded, then the nozzle is coggled and you can proceed to the next step.
Take out the filament and increase the temperature of some degrees. Now take the smallest cleaning drill and enter it inside the nozzle rotating it gently. Once the cleaning head is fully entered, take it out and proceed with a bigger one until you get the one of the same diameter as the nozzle (usually 0,4mm).
Once finished you can proceed with a deep cleaning using a specific filament for nozzle cleaning (like this). Remember you don’t need to use too much, 20-30mm are enough.
How to prevent nozzle coggling
To avoid coggling the nozzle you can use some tricks. Usually, a nozzle coggle because of impurities in the filament (like dust). Impurities can also be inside the filament if it is a bad lot or a cheap brand.
To solve the external impurities problem we can adopt a really simple solution: we can position a sponge around the filament to capture the impurities. You can easily print this tool from here.
Once printed the model you need to insert inside it two little sponges as in the picture and place it just before the filament to enter in the 3D printer.
Another reason for the nozzle to coggle is to have some filament that cools and solidifies inside it. You can solve this problem simply removing the filament from the printer as soon as 3D print ends, or you can add at the end of the GCode the command G1 E-200 to automatically retract the filament at the end of the print.
Remember also to always print every filament at its correct temperature. Always read the box or the filament’s datasheet.
