Thanks for your reply. I kinda tried that, but can't really reach every spot. Especially behind the point where the thread ends and there is a little gap to the next metal part, it seems there is a lot of stuff stuck.
I was a little bit successful by heating it up repetitively and screwing my steel nozzle in and out, again and again... plastic got stuck in the thread and I could get a bit out that way.
At least I can now change nozzles when I heat the block up enough, because the burnt part of the plastic that was stuck seems gone... as soon as its cooled down, it is hard as rock though. Now I am afraid that more of that stuff will burn when I do a longer print and get the nozzles stuck again.Edited by Guest
You should be able to heat the block up with the printer without the nozzle in their and then use your needle again to clean the block.
