Hi, the BB core of our ultimaker 3 extended seems to be clogged very badly. I have tried repeatedly the atomic method to solve the problem, but it never worked. The filament won't come out of the nozzle. I took a look inside the nozzle for a better understanding of the situation and as I can see, there seems to be a huge chunk of melted filament in the way.
I haven't tried the needle option yet, because I don't own such a needle, but it should be the next step. Still I don't have much hope for that solution because of the state of the nozzle.
Does anyone already had that problem before?
