Print Core Jammed in Ultimaker 3

[Ivonna 0]

Hi all,

Has anyone encountered the problem of a jammed printcore? In using my UM3, the AA nozzel became unusable strikingly fast. After about 25 prints (~70 hours of printing) the printcore was completely fried. But now as I'm trying to remove it, the darn thing seems completely jammed. I've properly cleared the core and have retracted the material several inches, but I just can't get it to wiggle.

Any help would be hugely appreciated!

Thank you

Hi Ivonna,

Thank you for your post. I'm sorry to hear you seem to have some difficulties with your print core. Could you perhaps illustrate your story with some photo's? Maybe that would make it easier to identify the exact problem.

Before it was stuck, how was your last print? Did your last print go fine?

Thank you for your time!

To remove the print core make sure there is no filament in the "trumpet" (that top part of the core). Then let it cool completely. then lift a bit on the nozzle while you squeeze the finger things together (the black and clear tabs). And then pull out firmly.

If you are removing the right hand core I think it helps to lower it first but it probably doesn't matter.

I have had zero issues with cores. I have issues with some things but my cores extrude just fine. All the time.
