Hello everyone. Im quite new to the 3d printing and I'm not too sure how to fix few problems. What im struggling with is mk2s keeps clogging with original fillament and extruder motor skills steps leading into failures. It happened a few times before but usually all I do is set temperature to 280 degrees and force the clog out which has worked, but now my 8h print has failed at 96% due to a clog which really annoyed me. So I have taken it apart and i found the clog not in the nozzle, not in the cold side but rather in that tube between the two. So I have heated it up and pushed out the clog. I dont want to put everything together again just to have it clog again. I thought before I do that ill ask someone with more experience. I have tried to clean out the tube completely but it seems solid. It looks like the tube wasn't drilled all the way through ? And when I push fillament through it creates small resistance. Could that be there intentionally ? To stop molten plastic climb up around fillament? Or coild it still be plastic ?
