Filament (tough PLA) stuck in the print core


Recommended Posts

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

Hi,

 

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

 

thanks

    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

     

    cheers,
