SOLVED UM3 extreme clog midprint...

[Handmade 0]

Dear everyone UM,

We have been printing with the UM3 for about a year now without any big issues.

This weekend however, something went terribly wrong.

Somehow, this giant PLA clog formed around the nozzle, eventually pushing out the front fan cover (see included pictures).

Now, we have no real clue on what has happened and what do next?

We have not used a new routine for printing than we have always used and never had anything similar.

What I suspect is that the fan cover might have opened up during printing (one of the magnets did come loose before), forming this bucket for the print material to clog.

Only, I have no idea what caused the front cover to open. Anyone any suggestions?

I have dismantled the print head and now just have the big clunk of PLA stuck to the print cores.

Any idea if it is even doable to remove the material and any tips on how to remove it?

Any help is greatly appreciated!

Kind regards,

Jesse

please contact your reseller to help you out.

you can slowly warm up the core a little bit and start removing the PLA but you will probably need a new aa core and probably a new fan bracket.

Nothing actually printed? Usually this happens when the print detaches from the plate.

I guess it could happen that the front cover opens itself somehow and this would certainly cause a mess.

As korneel suggested it is cleanable but you probably need some new parts

Hi guys,

Thanks for the responses.

Managed to clean the Ultimaker, just one printcore sacrificed.

We have contact with our reseller, so we will see from here.

Cheers,

Jesse
