Solved Jammed nozzle!

Hi there folks,

I would like to first mention that I have the Hexagon all metal Hot End.

I was just beginning a print with some relatively new material (I have used it once before) and I found that no material at all was put down on the bed. I stopped the print and checked that the extruder wasn't eating away at the filament, I then heated the hot end up to try and remove the filament and it wouldn't budge!

I ended up using slightly excessive force and broke the filament off just below the hole after the extruder. I proceeded to remove the hot end from the main body, heat it on up and tried to pull the filament out of there. Still nothing!

Finally I bought a guitar e-string and tried clearing out the nozzle end while hot and found I could get the string up as far as the material started to become solid so it seems all clear.

Can someone please give me some advice as to how to remove this piece of filament from the hot end so i cant get printing again?

Thanks alot!

Matt

 

Heat it up (170+) and just pull it out.

 

Agreed. If 170 doesn't work then keep bumping it up until it does. It should either pull out or you should be able to push it through the hotend.

 

Aha! It required a hefty tug with a pair of pliers, turns out the filament is ever so slightly too thick for the hot end. Not sure whether it is the whole reel or just a section of it. Thanks guys

 

I got the material from 3Dfilaprint.com, does anyone know if this is a regular problem from external suppliers?

 

Measure the filament diameter with calipers.

Also ensure your hot end fan is running.

 

The hot end fan is running fine thanks!

I have come to the conclusion that there is variation in the thickness of the filament which caused the jam, just need to decide whether I can use the rest of the spool or whether to send it back.

Thank you everyone for your help
