Thanks so much for showing this! There was a small piece of filament, just like you said, easy to clean out. About to put it back together and hopefully start my first big peint on my N4 Plus
I've had my N4 Pro since release. A couple of things I do to avoid this issue are always let the hot end cool down before turning the printer off. If you power it off before it has cooled, the heat from the hot end will climb up the tube and melt the filament. The fan will power off by itself when cool. On older printers, just make sure you are below 70c.
Thanks for the information about this problem? I have the Neptune 4 Plus and it is a new 3D printer as I only had it 3 Weeks now! I was printing fine with it using a new 0.8 mm hardened nozzle instead of the normal Brass 0.4 mm. I had just changed over to a 0.4 mm Hardened nozzle as I needed the finer printing again but just had the extra hardened nozzle sizes and thought is be better to use them? I had a long print over night and saw in the morning the print had not been done just a few layers. I thought like you that the nozzle was blocked, So I did the normal un-clogging by heating up the normal higher than the printing I been doing and tried to remove the top filament 1st and it broke off just on the top of the entry hot end hole on the top of the head. I checked and there was no melted filament coming out of the nozzle! I normally would remove the filament then use cleaning filament to help clean out the hot end insides and the nozzle. I found that the cleaning filament could not enter the feeding hole at all? I at first thought then it must have a broken off bit of filament in the top section of the cooling zone above the heat break? But I think it is like yours now as I taken the head apart and there is no filament in the top of the cooling section or the nozzle so it must be in the heat break! You said to undo those two black small screws to slide out the heat break But mine won't come out at all? The screws are most of the way out so those are not holding it in, so why won't it slide out on mine? Like you I think the design of the hot end is bad, making it hard to do this sort of hot end repair work! My Qidi X-Plus-3 hot end and extruder is far better to strip down and fix clogs and jams. It just a few screws to take it apart and the extruder is a nice simple design with two screws to open it up fully and take the gearing apart to clear filament jams so easy and it's hot end is easy to do too. Shame Elegoo did not think like this when they did theirs? I thought about buying a un-clogger, But it is very pricey here in the UK at £19. Any idea why my heat break and heater block will not come out?

Oh absolutely, that's why I pointed out that when you run long prints or many back to back you can get heat creep
Now this would be good information to know!!! I love my printer but the documentation is sparse!!!
Try running the clog needles through the nozzle when you first put a new one in it seems to help get rid of roughness from factory
Oh I have used the needles before
