Hi people,
Im having a lot of problems with my UM2, it started 1 month ago, now its impossible to make a single piece. I checked a lot of threads and used your advises but now im just lost, nothing worked.
The print start normally, but passed 2 o 3 min, it starts to and the filament clogs. When i pull the filament after this, there are always a ball bigger than the tube.
I did the atomic method, and the filament is always damaged, no matter the times i do ( last time i did like 10 times and the result after 4-5 was the same).
I used a 0,3mm hypoalergenic needle to clean the nozzle, but nothing changed.
I tried to eliminate the tension on the feeder using just 1m of filament, but the tension is not here.
I thing my teflon coupler is the responsible of this,
sorry for my english :(
Any ideas?
