Failed Print not noticed-Filament Backed up into Print Core-Jammed

Recommended Posts

Hello,  I had a failed printed  on my Ultimaker 3 that I didn't notice.  The filament backed up (badly) into the two print cores, but mostly into core 2.  I am trying to remove the excess filament, but it is a glob.

The good news is that the UM3  will still extrude filament  from both nozzles.

The bad news is that it is so jammed, I can't change the print cores.

I keep heating up the print cores and trying to scrape off the blobbed material.  I then use a need nose pliers to pull stuff off.  I then cool it down and try again.

 

Any ideas on how to remove the GLOB?

 

Thank you.

 

Tricia

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
