How to clean the Bondtech extruder (Sigma Series)

It is necessary to keep the extruder gears clean, in order to avoid printing issues.









After some hours of printing, or if you have experienced under extrusion issues, it’s possible that there are rests of filament on the bondtech gears, which could cause issues when loading filament or printing.




If you have an air compressor, compressed air can or a soft brush you can clean the bondtech extruders externally.

If you need to do an in depth cleaning of the bondtech extruders, disassemble these, and then proceed with the cleaning and reassembly.
