Hey is it still working fine? I got mine and loving it my only concern is people commenting with problems I have yet to see any my only problem so far is during the print the extruder plugged. And it paused it then I hit re try 3 times it un cloged and started the print were it left off no failed yet
I had a lot of issues with mine when I first got it, and they seem to mostly have subsided. I had some issues with filament with the CFS enabled but eventually I realized the sensors were bad on my CFS and Creality finally sent me the replacement hub a few months back and it’s good now.
I still haven’t tested much PETG, but I’ve probably done 100+ hours of PLA with the K2 Plus without the CFS. It’s great with PLA. Absolutely no tweaking required and 0.16mm structural prints come out with almost indistinguishable layer lines.

Sorry for the very late reply. I bought a K2 Plus Combo during March and absolutely love it! A few points to be aware of if you haven’t made your purchase yet, or for anyone else looking to purchase one.
- The CFS cable to the printer, or perhaps the connector in the printer, can cause connection problems. Mine worked perfectly until I accidentally bumped into the plugged in cable. Slowly moving the cable while plugged in solved the problem and it hasn’t recurred (yet). I’ll take the time to check if it is possibly broken solder at a later date.
- The connectors used to hold the tubes that guide the filament from the cfs to the buffer, from the buffer to the machine, and from the external filament to the machine, can be a bit difficult to manage, especially if you use them single handed. I made the mistake of trying to pull the tube out of one without pressing in the end of the connector (which releases the tube), and managed to damage one. Fortunately the machine does come with 1 spare, and after breaking one I’m not making the same mistake again!
- When changing between colors, you may end up with more waste material than is actually printed into your print. Something to keep an eye on.
Other than those little issues, the printer has been an absolute dream to use.
I’ve had my K2 plus for about a month now with two CFS units hooked up. I’ve had little to no issues with it aside from the CFS units getting jammed on occasion with the spring tension on the four-way spit being too much there’s a couple of fixes for it on YouTube. Other than that great printer good speed good quality. If you’re going to get into bigger printers like this, especially a new series then there’s bound to be some growing pains, but overall great printer, and worth the money in my opinion.

I had that problem with PETG. Fixed with setting changes:
Speed of the first cooling move: 2.2 → 20
Speed of the last cooling move: 3.4 → 10
Number of cooling moves: 4 → 6
I haven’t had clumps of PETG clogging the nozzle since making those changes. That said, I also reduced the print temperature, because after replacing the nozzle hardware and the main board, it no longer was (as best I could tell) running 20 to 30 degrees cooler than it said it was. 
So there were a lot of variables for me, and I can’t say for sure whether that will actually help you.
I have had my K2 Pro Combo for only 3 days and I can honestly say this machine is an absolute BEAST!!!
I love it to bits. Upgraded from Ender-3 V3 SE that I still have.
Straight out of the box has performed beautifully.
This was my first upgrade from the Ender3 series. From initial setup to first print it would be perfection compared to what I was use to lol.
The K2P has had a few little quirks to iron out but overall has been a very solid printer. First upgrade was the graphite bed and once leveled it is never more than .018 at any temp. Second upgrade was the hotend, this has better heat-break cooling.
I did have to replace the pressure sensor the nozzle mounts to as it had a defect that was slowly getting worse the more the printer was used. But with over 2000 hours of use I really won’t complain about $15 parts. As for the CFS units that a lot of complaints are about, mostly user error. Don’t leave filament sit in the CFS for weeks then wonder why it breaks and jams the unit. Had 4 units connected to the K2 and eventually moved 3 to other printer’s since I would very rarely print with more than 4 colors and swapping filament is a breeze.
Other than that, any other repairs I had to do was just maintenance or from user error.
As another has said, I may be a little bias towards Creality products as I run 5-K1 Max and now 2-K2 Plus units. Plus still use the Ender3 V3 Plus, Ender3 V3 KE bed slingers, a custom built 450x450x600 XY (mostly Creality parts), and 1 Non Creality AD5X which literally will sit inside a K2 Plus.
Second reply on this thread. Now coming up on a year of printing on and off. Over 800 hours on the printer. Various relatively minor issues. Power/sensor board for the hot end had the pins break. Creality replaced under warrantee and I rebuild the original which is still working surprisingly. Have been testing out a number of other filament mfgs, the worst so far was Sunlu easy ABS. Most of my printing is with ABS and easy abs is very finicky and not like ABS much at all. I did get it to print but even at half price the hassles were not worth the time lost. No issues with other Sunlu or other mfg filaments to date. A fair bit of operator error which the K2 has shouldered. Replaced the extruder shell as the PTFE tube fitting is a design flaw and I am still working on something better. The CFS recently pack in and would not feed with over retracts and loads of FR2836 (and others). Days of debugging and only being able to print from the external spool had me running the CFS with the combiner out. Seem there was a bad batch of optical filament sensors that was used in the CFS and a chat with Creality with video showing no filament in the sensor but it detecting it has a new combiner on its way to me. Truly fantastic customer service. I have done some board level sensor removal and bypassing had have a 2 way combiner for now and some new optos inbound. A word to the wise, U4 is for slot A1, I took out U1 and it broke hence a 2 slot not a three slot lol. We shall see if I can rebuild a 10 dollar board for several thousand in labour (I am not cheap!) and $15 in parts. After nearly a Year I would still recommend the K2 Plus. Solid printer, can be finicky but support is excellent! Update on the rebuild. Both channels with the Omron optical sensors failed BUT failed off so I did not have to hot wire them so I was back to a two slot. I did buy a new sensor board for $20 and it arrived before the warranty replacement. Put it in and all is working fine. Still would recommend.

Looks like how my K2 Pro arrived. Fedex apparently likes to play dice with heavy things.
I bought a Creality K2 Combo from Creality Singapore, and so far everything has been working flawlessly 
What really stood out to me was the after-sales support — the staff were very responsive and patiently answered all my questions. Overall, a very smooth experience and definitely reassuring for a big purchase like this.
Not many announce positive feedback, they only post their negative experiences 99.9% of the time.

I have had great experience with creality support all 3 times I had to use them last year. They were responsive, helpful, and sent me the parts I needed right away.
こんにちは。今まで、プリントは外注に頼んでいました。外注先からFDMは受け入れが出来ないと言われ、昨年8月K2ProとCFS２台を購入しました。３Dプリンターは初心者です。２ケ月程で歪みセンサーエラーが起き、ドンと言う大きな音とプレートをノズルがひっかく音がして何が起きたのか？どうしたらよいのか分からない時間を経験しました。サポートによりホットエンドやプレートなど交換部品が送られてきました。それから大きな問題もなくプリントしてます。（エクストルーダーにカッターが無かったり、チューブにフィラメントが詰まったりはありました）３Dプリンターの出来ること出来ない事をRhinoserosでデータを作り確認してますが、私にとって外注していたプリントの仕上がりと比べて素晴らしいと思いました。造形時間も１/３ぐらいに短縮。
皆さんの様に設定を変更して使うほどの知識やレベルはありませんが、K2proCFSは私にとって頼もしいパートナーと思います。エラーが起きたらサポートと連絡を取り問題を解決する事だと思います。
Biggest headache I’ve ever had with a 3d printer. And the support feedback is non existent
I’ve had a great experience with the Creality K2 with CFS — smooth printing, reliable performance, and easy setup. Worth checking out!

Coming up on a year of printing on the K2 plus. 9 kilometers of filament, 611 prints, 930 hours of uptime. Longest print 25 hours. Moderate use in my books.
FYI, Fluidd is a far better interface for finding the above information.
Creality print has been more than adequate for all my printing needs though. On the latest rev now.
Two needed contacts with Creality support. One for hot end connector board and one for a the CFS 5 way sensor board. Both fast, efficient and got me running. I bought or repaired both for restoring immediate operation though.
The K2 plus is still my go to printer of 5.
I have a number of epoxy build plates and a number of spare parts. I have modded the CFS for gravity hold down (not springs) with more travel to allow the use of different diameter filament spools. I have modded the bowden input to the hot end and changed out the connector thrice, still not completely happy with it, work in progress there. I have modded the CFS buffer by removing the tape inside it between the spring and the housing and just LIGHTLY greasing the housing where the spring contacts the housing. It was tearing up the tape and causing spring issues. I also added a free end locating screw to hold the spring in line with the internal slider so the spring would not buckle sideways during buffer operation. No more issues with that now.
Over the course of the past year the Creality presets in Creality print have become significantly better and have noticeably reduced print failures.
It can be finnicky on first print after protracted downtime but is getting better.
After the third try of doing the same thing I was finally able to upload one of my designs to the Creality Cloud today. It had been user hostile until my second try today, no idea what it did not like but seems to work now?
Overall, kudos and thanks to the Creality team for a capable piece of equipment, quite good support when needed, the dedication and honour to continue the improvement of the printer and its surrounding ecosystem for the past year. Keep up the good work.
I have a K1C and a K2 w/CFS. The “K2” has been an absolute breeze and i seriously question the sanity of youtuber’s when they show their final prints and say how great it looks, when mine look 10x better with no effort. Full disclosure im only printing in Hyper PLA/PETG and just started with PCTG.
Highly recommend the “K2 with CFS”, even if the price were a bit more.
With that said, I’m going to point something out that no one seems to care about but makes me furious beyond belief…
I have a K2…
NOT a K2 Pro
and NOT a K2 Plus
Which makes searching for things related specifically to my printer an absolute PITA!
Searching forums, print settings, filament settings… even in this very thread, people refer to their K2 Pro/Plus as just a K2. Ex: If someone is referring to their K2’s chamber heating, that means they have a Pro or Plus.
So you have to be careful when troubleshooting, that your not following advice for a different printer.
Regarding the negativity towards the K2’s, i can only speculate that the original K2 Plus (2024?) came with some issues and that was the only model K2* available until 2025, when the “K2” and “K2 Pro” were released.
@CREALITY Please,please,please rename the “K2” to the “K2C” or similar.

I have had the worst time with the customer service. We got our K2 Plus with 2 CFS for Christmas and it stopped working January 7. We kept getting all kinds of errors. I have reached out to customer service through multiple mediums after troubleshooting everything we could find on the site. They take multiple days to get back to simple questions via email. Then they tell us to troubleshoot with their videos that we’ve already watched. I have NEVER been sent any replacement parts - only told that I can’t return it because it’s outside the 30-day return window. I have no idea how to get help for this. @CREALITY I need someone to provide a resolution now that it’s coming up on 3 months!!!
I have the same experience looking up stuff…infuriating, at best.
I have had a similarly good time thus far with minimal issues with the same “K2 w/ CFS”. I also have the diamondback 0.4 nozzle and it works pretty great, I have had no clog issues since changing up the nozzle
Sounds like some BS post.
We bought the K2 combo last week, arrived Saturday, complete newbies on 3D printing, so we did not change any settings.
With the standard Ender Fast PLA I started with a box cutter, a scraper, yogurt lid (added embossed text), all flawless printouts.
#4 was a poop chute (3D Printer Files | 3MF File | Lightweight Creality K2 Poop Chute-Purge Waste).
Man, that looks so perfectly satin smooth I know it couldn’t be bought any better.
One of the plus is the Linux version of the Creality Print slicer software.
