Filament (tough PLA) stuck in the print core

Recommended Posts

Posted · Filament (tough PLA) stuck in the print core



I sent a print job with tough PLA. It was working normally. When I went to check the printer the material wasn't coming out the print core 1 (AA 0,4mm)


The filament was broken in several parts inside the bowden tube. I remove it


Then I heated up the core to 240ºc and push down with a piece of filament. It didn't come out. Also pushing in with a needle. It seems it doesn't melt. It might be stuck in a position where it doesn't get hot.


After a lot of work with a small utility knife and managed to cut the filament right above the print core to be able to remove it (is there an easy way to do this?)


What can I do?


I understood I can't dismount the print core. I might damage irreversibly

    I managed to remove the filament.


    First, I drilled a hole of 1,2mm. It doesn't have to be that size, but close


    Then I put in a small screw and pulled.


    With the help of a thin fiber I had I checked and the path is now clear


    I had mounted and calibrated already a new core so I won't put this back, so I don't know if it works properly.


    In any case, here I leave this info in case it helps somebody
