Ultimaker S5 Print Core AA meltdown

Recommended Posts

Posted · Ultimaker S5 Print Core AA meltdown

Hi Community,

I am using the Ultimaker S5 Pro Bundle, which had worked fine since delivery (2 months).

But this morning, the over night print job was ruined due to a melt down on Print Core AA!

Please see pictures attached.

I replaced the defective Print Core with a spare Print Core.

During startup of the first print job after Print Core AA replacement, an error ocurred, telling that Active Leveling could not be performed.

This happened twice.

I investigated the Print Head, but could not find any anormalities.

But somehow it seems that the Print Head has been misaligned by the defective Print Core.

I took a picture of the empty Print Head. Please see attached.


Can anyone help me on this issue?

Best Regards.

Hi again,

I investigated the Print Head once again, and I found that the small metal sheet at the bottom was bent.

You might be able to see it on my last picture.

I took it out, made it flat, and assembled the Print Head with Print Cores.


After this, I was able to start a print, including the Active Leveling.


I guess that I accidentally had bent the metal sheet during removal of the defective Print Core.

Since a lot of printing material was melted around the Print Nozzle, some material did also stick to the metal sheet.


So the problem is now solved.

How do I mark the post "Solved"?

No worries, fixed that for you! You can add it as a new tag. Happy to hear you got it back to work.

      Through this post I would like to further explain what we are doing, and what you could be doing. 
      Our efforts consist of 2 layers. First; connect medical institutions and hospitals to (local) 3D Printing hubs to help them print parts of which a 3D model already exists. And second, contribute to design the necessary part and then have it printed via a (local) 3D printing hub. Experts are available from within Ultimaker and from within our network of 3D printing experts.
