I got my K1C exactly 3 months and 1 day ago and just now got my first filament jam. I'm very use to taking my Ender 3 S1 Pro hot end apart to have to fix a jammed filament, and it sucks. It takes forever, I usually have to take a lot of parts off (and even take the hot end off of the carriage). So I was expecting it to be similar (or worse) for the K1C.
To my surprise, it was very easy and quick (thanks to this video). I was dreading having to put the hot end back on and run some calibrations or test prints, but I was able to fix this jam in about 10 minutes (would have been even quicker, but I couldn't lift the extruder part out of its seat) without even taking the hot end off of its carriage.

Im on Reddit a lot and I see people give a lot of crap about this printer. I almost didn't even get one because of it. Im very glad I decided to try it out. I will probably even get the K2C (with AMS) when it comes out.

This is exactly what I needed & I’m back to printing with no issues now. Thank You!

[BillBard]

First week of owning the K1C, had my first jam last night. This video was just what I needed! Thanks!

Done this multiple times with a month old K1 over the last 4 days. New type extruder fitted from factory. Still jamming after 30 minutes of printing. Replaced the hot end with a Micro Swiss Flow tech today, and it's still doing it. I've just sent Creality support email asking for a replacement extruder. Not happy to be honest. If it still does it after that I'll try and return it. Will go back to my old Biqu B1, as that was bullet proof.

Wow this worked for me. I found a very tiny piece of filament on one of the wheels inside, Thanks

i have a feeling that its because you guys made where the ptfe on the top and buttom connect is made to narrow so when filament is abit larger it will cause a jam ! its the outer part of the extruder i talk about that you take of in the video ! the round circles has a middle part where the filament is guide though ! that can be damaged to i have seen many where the tin wall has broken because of a jam ! might help to drill the hole abit larger also makes it more easy to load the filament to =) remember to align the gears correctly !

[mjethier]

just had to do mine. wasn't jammed in the extruder but between the ghetto setup of the heat-break etc. Creality didn't respond to my tech support question for 6 days straight. Took it upon myself to diagnose, repair and order a micro swiss unit so I don't have this BS happening 10 minutes into the 2nd ever print after the benchy.

Not cool. Not cool.

Beautiful machine. Reminds me of my bambu units which seem to be software aside, rock solid. Time will tell.

[LukeyBoyAndTheCatlings]

I don't know why but I kind of enjoyed taking this apart and fixing it.
I can get enough of this machine 😂

[eltonq]

Mine is jammed after the blue tube and before the nozzle in what looks like a cylinder. Help.

[yudylorenarojas]

Hi, very kind of you. Do you know if the extruder motor of the Creality K1 can be repaired? One of the cables came loose.

[nikanasto]

Why can't I disassemble the extrusion so simple? It seems stacked and I'm afraid to push any harder. Does this happen only to me???

[berniemailloux]

Mine just needed a few degrees more in nozzle temp and it works fine now

[karellamac]

no to se ti to vytahuje novy filament :-D ale ve skutecnosti je zkrouceny, vyhraty narvany jak v trubicce tak tom tenkem pruhodu, pri tisknuti malych ploch je toto zasekavani extruderu porad dokola, po desatem rozdelani se vam pro jistotu jeste vytahne konektor od motoru, je to past vedle pasti. nekupovat!

[DigitalGenXer-zisu]

At 45 seconds into the video the operators lifts up and removes the extruder. Mine does not come out. Why is that?

[Tippedten]

So it’s the same thing but it’s stuck lower

[rubensdecarvalho]

You are the best, thank you very much.

[AlbertoHernandez-jmxk]

Dia uno con la creality k1c, primera impresión con la creality k1c ¡y ya tengo que estar desarmando la maldita porquería que lleva unas horas fuera de su caja!

[squirralien]

That’s fine, but why is this jam appear to be common and how do we prevent it.
My K1 Max has done this after after less than 20 hours printing, my two Dnder 3 S1 Pro’s have done hundreds of hours each and never happened.
On the K1 Max it has done 3 prints perfect and then the third has messed up the first layer a little and then I think it was the third layer it was jammed.
Is it a poor extruder?

[Jonathan-lake]

I got my extruder out when I did that accidentally ripped the wires off the motor. Be careful

If you're lucky and stuck here, this might be a good solution. But unfortunately, the wire gets stuck in the cooling fin, which requires the whole thing to be completely disassembled. If you're a regular, you'll have it in an hour. Fortunately, it only happens once a day.
