I tried to get help on this in the quick help, but had no luck. I'm waiting for creality support to get back to me about this too. But have no idea about their timeline and would like to get this sorted asap.
I have an Ender3 V3 KE. I was changing PLA filaments and the new one would not feed through. The blockage is in the part with the metal fins (heat sink ?), just above the nozzles and umm hot end (?). Creality give you a long pin tool to clear blocks and I've used this before with good results. This time it remains blocked. I tried heating it up to 240 but that didn't help. I would appreciate it if someone had experience with a block like this that has some tips on forcing that blockage through, or another solution.
#How to clear a block in the heat sink (?) part, just above the nozzle

I have done methods 3 and 4 benchybot. As well as similar attempts as 1 and 2 describe as well, though not exact replications. I could not find any help on how to completely dismantle the entire extruder/hot end set up, though I did pull most of it apart, checked the gears and the nozzle etc. I'm not sure though, how to get the 'heat break' out or how much force is safe to exert on the part.
For example, with my trade background, I thought of taking the nozzle out and using a drill bit and a hammer to force the blockage loose, then push it back down out of the tube. However, I don't want to damage anything. I'd prefer not to have to buy a new part as the printer is basically only a month old.

Still hoping for someone who's had a similar problem that might be able to offer advice 🙂

Did it like this? Don't need nylon filament

Thanks mate. I'd not heard of that before. I'll try it. I did try it with the hot end at about 30. But I'll watch the video now and give it a crack 🙂 Much appreciated.

The automatic bot responses are kind meh sometimes
A few pulls is usually all it needs
Make sure to take the tension off of the exruder while pulling

ok I will not forget to do that. Watching the video now. it says to begin with to heat up the hot end as high as it goes and then retract the filament. I'll do that first. Mind you I already took the old filament out. but I wont skip that step.

I was having no luck with a piece of filament. So I used the long pin Creality give you to clean blocks out with. And at 300 I thought I'd done it. It broke through. Right down to the nozzle tip. smoke would come out the tip as I poked it. But I couldn't get the filament to go through any further than before. So I tried cold pulling it with the pin tool, but although it got a little, it still hasn't cleaned it enough to feed filament through it. And the guy in the video did say if you don't have a bowden tube you'd have to pull the gears apart... well the KE is a direct feed, so no bowden tube and it does have gears. I wonder if there's a plastic sleeve inside that area that might need replacing ? I can't find a schematic or video showing me that set up to know what parts are in it. I remember seeing one video where the creator was talking about replacing the plastic tube with metal ones. I'm just not sure if it's in the same place or if it's relevent to mine. Any further tips by any chance ?

KE has an all metal hotend so no replacing needed as far as I know

ahh right. bugger lol. I guess I'll keep trying to clear the blockage and see how long Creality support take to get back to me ?
tame sorrel
yes. I've used that to clean a blockage before that was giving issues. It's just a basic clean out. This is much more stubborn 🙂

Right. I thought I'd update this in case anyone (especially newbies like myself) with the Ender3 V3 KE has a similar issue with a jam or blockage. I had pulled apart most of the extruder etc, but I wasn't sure how to get the 'heat sink' off(and I did have the right name for it originally), and I had no idea what it all looked like inside it. It turns out the 'heat break' actually goes up into the heat sink, which is where the actual jam was. So once I got the heat sink off, and could get at the grub screw to take the hot end and heat break off the heat sink, the jam was fairly easy to clear since I had run it up to 300 for a while during attempts to 'cold pull' the blockage out. It crumbled up well and then by removing the nozzle and plugging it in and heating it up, I got the last of the junk out from inside it. I put a new nozzle in it, because I had had enough of mucking with it for now, and didn't want to try and rescue the nozzle that was in it. But I might do that later. Anyway, thanks @m.von.wo? | KP3S Pro S1 Klipper, for leading me in the right direction and giving me some needed advice. I also want to share this video which is how I found out how easy it was to get the heat sink off. I am printing my first print post issue now and it seems to be working great. Now I just need to find some spare nozzles to fit it in Australia lol.

you need to retype that into a single line, edited wont work 😄 glad you got it in the end
