To achieve faster speed printing for functional and draft prints, I wanted to try a 1.0mm nozzle with my Neptune 3 Plus. This is the first time I replace a nozzle so I followed YouTube videos and replaced the nozzle. After replacing the nozzle I leveled the bed with manual + automatic leveling. The extruder seemed to be working, taking and extruding the pla filament. Success? Sure not yet .
I started fiddling with cura profiles, increased line width, layer height, temperatures for head and bed, decreased speed.. Tried a few times to achieve adhesion and printing. So things looked good. After the trial and errors I was satisfied that I could print now.
I started a 1 and a half hour print. It started well and I went for some tv and started checking the video feed. Things started well, but in time some warping occurred. It was evident that the print would fail. However I wanted to see how things will end up so let it continue. Sure it ended with some spaghetti.
Everything is as expected up until now. So I returned back to stop the spaghetti. But there was a strange blob at the end of the extruded filament spagetti. And the nozzle was there?!? I am still confused how the nozzle ended up out of the extruder being intact.
Yes exactly this is.
After this I used a 0.8 nozzle. And could print with it. So threads are still there.
I suppose I mistakenly didn't fully screwed the 1.0 nozzle. With the large layer width Pla stuck on the nozzle, as the print was a rectangular shape on each turn that pla applied some tork and nozzle unscrewed.
