Hello everyone, I am currently suffering from kind of a problem with my Ultimaker 2+, which worked flawlessly up to this day. I really wanted to contribute to the community soon, so having to ask for help as my first post is not really how I hoped to start here.
When I wanted to switch my nozzle today, the nozzle wouldn't even move at all. After like 20 minutes I finally got it out, with way more force than I like to put on delicate parts like my print head. It was so hard to turn it, that even my 3d printed torque wrench gave up and broke on me. I hope my print head is ok.
Now, I have already figured out the problem. It seems that some plastic, probably a string from when I changed materials and nozzles earlier on, got in between the thread of the nozzle and the inner thread of the Olsson Block. I even found some burnt debris inside the housing.
Now, removing it from the nozzle was easy with a lighter and a fine needle to make it a bit softer and then scrape it out of there... but I have no idea what I can do with the inner thread of the Olsson Block. How can I free up that? Does anyone already have to deal with that kind of situation and what did you do?
Thanks in advance for your help and responses!
