Hi, I have a K1 with extruder already in the updated version. I also installed a nozzle from the Creality Nozzle Kit, in 0.4 copper alloy. The first prints (cube and 3DBenchy) are perfect. The temp tower also printed well. Then I tried to print the test, downloaded from this Cloud, All in One, using the same previous settings (Pla+ 230/70). The filament gets stuck inside the hotend, creating a tangle inside. I thought the temperature was too high, so I lowered it to 210/70. I repeated the print 3 times and the hot end got clogged 3 times. I purchased a replacement hotend online in the "red" version (it should be the one from the K1 Max). Do you think it's a defect in the original hotend? Thank you.
