Hot Pull Clean not doing anything

Recommended Posts

I suspect I have a clogged BB Print Core on my Ultimaker 3 and I can't seem to get the Hot Pull cleaning method working no matter how much pressure I try or how long I leave it to heat up.

There is no extrusion of material and the print core won't load material.

Any advice?

recognise these? the clips inside garbage bags or small plastic bags for sandwiches etc.? Don't know if these are common in other countries... But they are perfect to unclog a nozzle, there are always plenty of them unused, and the metal strand inside is small enough to enter the nozzle and doesn't damage or break anything.
