Hot Pull Clean not doing anything

Recommended Posts

Posted · Hot Pull Clean not doing anything

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?

What material are you using for the hot pull? Are you also up for reaming it out with a needle? I have used an old airbrush needle when needed. Gotta be real careful with that or you can make the nozzle bore misshapen.

Using Ultimaker PVA. My colleague suggested using a pin to try and clear it out but I wondered if there were something I should try first or something I'm missing with the Hot Pull technique?

Thanks

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.

Are those stiff enough to poke through solided up, cooked materials?

if you hold it with pliers (no finger burn) close to the nozzle and shove in it bit by bit. It is soft, yes, but very available. For harder wire I use strands of a metal wire brush.
