UM3 Stuck Printcores

[neo-ninja 1]

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?

Did you remove the filament from the top?  Sometimes I still have the filament going into the core and forget you can't pull them out until you remove the filament first.

 

The whole head comes apart if necessary:

By the way it sounds like you are describing a head flood.  It can be caused by your magnets not gripping well - if so pry them out with a screw driver about 1/2mm.

 

Or it can be caused by your prints not sticking to the bed.  Here is the fix for the second cause:

The cause was the print not sticking I was just a bit unlucky. The link just showed how to remove the cable is there another for the whole print head?
