How to clean the nozzle or clogging?

When the nozzle of your Printer is clogged or blocked, this will prevent the material (or hardly any) from being extruded. 

This may lead to incomplete print or under – extrusion problems.


After printing for a long time or switching materials from one to another. The hot end nozzle should be cleaned at the proper Temperature.
The following the temperature for each material for cleaning, the nozzle is mentioned below.
PLA - 210 to 240 degrees at hot end recommended.
ABS - 240 degrees at the hot end recommended.
HIPS -230 degrees at the hot end recommended.
PETG – 235 degrees at the hot end recommended.

For cleaning the nozzle first, preheat the nozzle to the corresponding temperature and unload the filament from the nozzle.

Use a long T shape 1.5mm Allen key to clean the nozzle from the top.


If the nozzle is not properly extruding checking for the clog and removing it is mandatory.
