Replacement hot end

[Newlands]

I’ve been struggling for the last couple of days with repeated blockages on my Creality 3 v2. I had bought a decent filament feeder some time ago which I hadn’t got round to fitting, so I put that on and calibrated it, with some improvement, but it didn’t cure the nozzle blockages. And every time I dismantle the hot end to clean it, the ptfe tube is impossible to remove as the fittings bite into the tube so hard it has to be cut.
Is the Micro-Swiss hot end a decent replacement?

Is the Micro-Swiss hot end a decent replacement?

Mine was, but took a bit of fettling.

I fited a hot end I got from a member here for my E3 but I have now replaced that machine and donated it to a local school. I do have a couple of spare E3 hot ends here that kind members had sent me so if you want them for spares let me know.

One thing I have found is that a loose nozzle results in the filament coming out through the threads and gives you a messy hot-end (ooer missus).

Micro-swiss is frequently recommended for the V3 KE. Nozzles are more expensive but I've only heard good reports of them.

Not sure why I didn’t think of it before but I’ve just had a look on YouTube and of course there are a million videos on this topic. At least I think I understand why the standard hot end is prone to blocking - what I found when I tried to sort it was exactly what others are describing - the plastic tube goes too far into the hot end and deforms with the heat. I think I’ll order a Micro Swiss as it has a heat break tube between the nozzle and the tube.

I might have to come back and ask you what this means. - I’ll have to level the bed again but that’s no problem, maybe have to use different nozzle temperature??
