    I installed my Revo 6 PE on my MK3S+ about a 10 days ago and have been changing nozzles quite a bit. it's great. Love the easy nozzle changes.

    But I've noticed now that I'm experiencing increased resistance toward the end of the installation of the nozzles. There is enough resistance that it is becoming hard to get it threaded all the way in with just my fingers, and unthreaded later on. (And the result of not getting it all the way in, of course, causes Z-cal issues.)

    It almost feels like there is extra material bits (like filament threads maybe) in the receiver causing this resistance. Though, close examination of the nozzle threads does not reveal any visible debris.

    Has anyone else experienced this?

    So now I'm thinking: How can I clean the threads without too much disassembly or potential damage? Maybe a (long) thread tap that I can thread in from the bottom to clear any foreign debris? Maybe compressed air from the top? Other ideas?

    My issue is similar in that I had thread binding on my 0.8mm nozzle when trying to remove it after using it for maybe 30 hours of printing. I noticed that there were some small imperfections on the male threads of the nozzle. When I looked at my other nozzles from the set - 0.25, 0.40 & 0.6, all had similar imperfections. They have been stored in the original box when not in use. The 0.25 nozzle has never been used. The marks are at about 45° to the axis of the nozzle and spiral around the threads.
