Filament is leaking above the heather block

Recommended Posts

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

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.

      A: Materials which are hard in a solid piece (like metals, ceramics and carbon fibers) will generally also wear down the nozzle. In general one should assume...

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
