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?
