Cold Pull
A cold pull works by pulling semi-soft material back through the nozzle, along with any debris clogging the nozzle. It works best with slipper, soft materials like nylon. Special cleaning filament can be used to clean the nozzles on a regular basis.
- Heat the hotend up to the working temperature of the filament to be used
- Push the filament through the hot end until the previous material is cleaned out
- Let the hotend cool
- Heat it again to 110°C and pull on the filament while holding the extruder release until the filament comes out.
- Cut off the melted end and repeat until it comes out clean and the nozzle is clear
- Typically only a couple of cycles are needed
