[filament clogging UMO+ /w imgs]

Thanks for the help. I think its working now.

I cleaned the nozzle and all the parts very very much, tested the coupler (everything fine) and so far i dont have problems. i think the issue was some alien parts in the nozzle that stopped the filament from pushing through.

The printer is 2 months old. I printed in many layer-heights, temps and speeds with good results.

Suddenly the Printer stopped pushing filament through the nozzle.

I opened it up, found this situation, cleaned it, closed it, used it and it happened again immediately.

It seems, the filament melted before it got into the peek isolator and clogged the hot end isolator.

What, why, and how to fix?
