Filament is leaking above the heather block

[Mirobieb 0]

We have a brand new UMO+. The first prints looked fine, but we probably made an error when we putted the nozzle in the heather block.

Now it's leaking filament above the heather block.

I tryed to fix it. But because there's filament every were I can't get it loose or tighter.

Is there a trick to solve this problem.

I think I have to get it all loose en clean it and then put it together again.

But i can't get it loose

Just heat it up and you'll be able to take it apart. The leaked plastic in the threads acts as a very strong glue when it's cold.

I used bottle of air to push the leaked filament with the head hot. But for safety reasons this is something you shouldn't do. But it worked for me. But don't do it

After that it was just a matter of atomic pull and tight the nozzle properly. (Don't overdo or the bozzle/heater block) can suffer.

Heat the block to 180C and then just start removing the extra PLA and then you can unscrew things while hot. Be gentle using wrenches as brass and aluminum are not as strong as steel.
