UM3 Stuck Printcores

Recommended Posts

Hey All,

 

I was after some advice my UM3 printcores are stuck. I had a massive pla disaster. Which covered the printhead in pla. I got it all cleaned off and the machine works fine. BUT i cant get the print cores out.They can move up and down just fine but will not click out no matter how hard i compress and pull.

 

Any thoughts?

    • "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.
