Did Creality test the K2 before shipping to customers?

Hello DeaconPrinter,
If you don’t really need colour change and all the hassels that go along with it …
I also have a Qidi Q1Pro as does @Bonfireman , and find it to be an excellent printer.
There is the added time taken before each new print where it calibrates, but, what you end up with is a perfect print every time.

Cheers.

I can say that alot of the errors people have are user error and lack of knowledge. I understand some of them are actually printer errors that Creality may need to address. But I’ve had my machines since release and I love them so much and they are so reliable that I am selling all of my k1 maxs to buy k2 plus machines. Plus, I e seen Creality’s quality control department. They literally print on every printer before it leaves their factory. I know shipping a big machine like this can result in some internal damage at times. So if you’re just ya ing a horrible time, the. I’d say you have some possible internal damage and need to swap printers. No reason you should have any issues on the k2 as I know many many people with the machine because I do 3d printing in my YouTube channel and they all have success. But we are all very experienced users also. So I’m not sure here. The k2 is def the best printer I e ever owned. Hands down.

I’ve had a very similar issue as OP. I’ve printed almost nonstop and with all kinds of materials with my X1C and P1S and the only issues I’ve ever had were related to cardboard spools and bad nozzle wiping, which were annoying but manageable with mods.

I decided to pick up the K2 Plus recently and it’s been a miserable experience. It’s well-known in the community that these printers aren’t just plug and play, so I’m not sure I would blame user error too much here. Try going to a Creality Facebook group and say you just bought a K2 Plus and that you’re surprised to have run into issue X on a brand new printer. Everyone will just laugh and go “you obviously didn’t do your research on Creality”. It’s truly a Creality thing.

I’ve had all of the following issues on day 1:

  1. Extrusion and retraction issues after 20+ hours of printing and filament changes. Once this issue started, it only got worse until I was no longer able to make it past just a few layers without issues. I was never able to complete this print.
  2. Creality Print absolutely sucks on MacOS (Apple Silicon). Also not very intuitive compared to Orca and Bambu Studio. Creality acknowledged a bug that prevented me from even being able to select the support filament. Workaround was to use the app or the touch screen. It feels like a Windows XP app that was ported to MacOS and barely making it. Hot, very hot garbage.
  3. The software on the touchscreen is horrible. Pausing will sometimes take an excessive amount of time. It’ll even get stuck “resuming” or “pausing” and you’re just SOL until it figures itself out, if it ever does. Toggling the light can even take a few seconds (yes wifi speeds and connectivity are great - 700 Mbps+).
  4. Resuming from extrusion/retraction issues or power outages is hit or miss. When it resumes, it usually (for me) ends up knocking over an object on the build plate.

It’s just mind blowing. A laggy touch screen in 2025 is crazy work.

I really, really wanted this printer to work because everything about it would fit my needs perfectly if it worked, but it truly feels like a product in beta testing. I’ve spent more time researching than actually printing.

Luckily I was able to return it back to Microcenter before things got too far out of hand. Hoping Creality fixes these issues sooner than later.


This is how I received the package. Thanks UPS!!!

cant imagine wat that package have endured

That’s pretty insane, lol. Not even worth opening IMO.

I definitely would NOT have signed for that.

I didn’t and refuse to accept it. Also filed a complaint at UPS. I also informed Creality EU about this and no answer from Creality nor UPS

This matches my experience. And I see you returned yours. I’m about to ship a second K2 back to Amazon for exactly the same problem — failing to extrude and change filaments. It fails almost 100% of the time.

Given how badly this behaves (and the first one was worse!), between the cutter getting stuck all the time (on both units), the filament jamming problems on almost every attempt to extrude, etc., there’s no way this product should EVER have shipped to ANYONE in this state.

This might be a fine single-filament printer, but it is completely USELESS as a multi-filament printer. There are just too many fundamental problems that will almost certainly necessitate a complete redesign of the print head from the ground up, IMO.

Mine is definitely a temperature problem. I just used an IR thermometer to measure my Snapmaker and my K2 both set at 240°C. It’s too small a target to get a perfect measurement, and the gun is cheap, so probably badly inaccurate, but after taking a few dozen measurements, the highest number I saw on the Snapmaker was 203°C, and the highest number I saw on the K2 was 173°C. This is consistent with my observation that it acted like the print temperature was off by about 40°C.

I think I have a bad temperature sensor. [redacted swearing]

’ I feel like the later production batches have not been tuned or checked like the ones that made it to the reviewers.’

You’ve hit the nail on the head there

Worst piece of junk I ever bought. That includes everything I have bought in my life. It is junk

same hear i have a 7 day old printer with a none working extruder (just jams for phun) do they care i dont think so they ask for proof of purches then ignor you for a day then tell yo to check out wicki and youtube i think this is a joke got on to these hear they ask the questions and come back with nothing

I bought a K2 plus with CFS about 5 weeks ago, it has done pretty much non-stop printing since I bought it, and I’ve only had 4 prints fail, and those were down to me not setting up the brim & tree supports properly (still learning with the Creality software). I used to print 4 years ago (with a CR10- S Pro v1 & v2) and stopped, but I am loving my K2 PLUS, it’s a beast!

You can find several posts here in other threads about the other problems I’ve had with this printer, all surrounding PETG filament. But most recently, tried eSun PETG - got it all calibrated and looking great - then the next morning, the nozzle clogged on the first layer and things snowballed after that.

Disassembled the nozzle - found the OEM heatsink grease hardened (already, maybe 50 printing-hours) and was barely effective. Rebuilt the (new) nozzle and heater with boron nitride paste. Discovered that the nozzle was overshooting setpoint by +15c… since I was already running the eSun PETG at 255c (top of its range) that means it reached 270c right before extrusion - leading to the clog. Self-inflicted!

Now it won’t feed, retract, nor extrude properly. Patience long-since gone.

That’s too bad because these are actually amazing printers. I bought 2 more for my studio and love them. If you still need help I’m sure I can help get you through your Aussie if ya wanna get it solved. It’s def not the printer. There’s something you’re doing wrong because they work great. Well unless you have a faulty printer all the way around. But I highly doubt that is the case.
