New Firmware Update (2026-02-02) for the K2 Series - Feedback

[LoriAnneBrown]

I have gotten that message a few times and use Creality Print so assume it is a bug they will fix soon.

I got my K2 Pro about a week ago. I first printed the included benchy and it worked perfectly. I didn’t print anything else. I then upgraded to the new firmware version 1.1.3.6. After that I wasn’t able to print anything. Not from Orcaslicer, not from Creality Print and not even the included benchy. I also did a factory reset, but that didn’t help. It’s always the same issue. The print starts calibrating and after that I get the message “Print canceled”. (I don’t remember any error messages). I now downgraded to v1.1.0.94 and everything is working.

New Firmware Update (2026-02-02) for the K2 Series - Feedback

Hello, a new firmware update came out (2026-02-02) for the Creality K2 Series printers.

I would like for anyone who did this update to give us your feedback, so others can finally trust it and proceed with the update.

I’m still waiting for the feedback to finally install it, as I’ve heard about some problems with older firmwares, mostly nozzle crashing and dragging through the build plate.

Many are saying that the best feature was the new UI, a lot faster and more functional .

Here are the main changes:

K2 SE - 2.3.6.49 - New printer, new update - It seems to OK. Vladimir

So I decided to update my K2 Pro although it’s been working fine since I bought it last year.
I could not despite all suggestions get it working with Orca Slicer. The file would upload, Orca would switch to the device tab and crash. The printer would just sit in the printing menu doing nothing. I could not pause or cancel the print, the only thing that worked was a power off reset.
I tried with Creality Print v7 and it has been working ok.

What I do not like is that Creality has released a version that crashes Orca Slicer, although the previous version worked just fine. I just hope that Creality is not going down the Bamboo Labs route of locking things down

Hi Lori, make sure you have the latest version of Creality Print, a new version came out last week.

[Nuno_Penas]

Yes, Dave, I’ve been printing since October almost 24/7 with that update (1.1.0.94) without a single issue. Maybe some printers have a different chip, it happened with my old Ender 3 S1 Pro, it had two different chip versions . Back then, I didn 't upgrade to the last update because it was too unstable. So, I recommend you stay with the former firmware and wait for a new release. I’m sure Creality will release a new firmware in the next few months.

Same happened to me after the update but on my K2 base. From Orca it doesn’t start printing and from Creality slicer it auto cancels the print. But on the K2 Pro the update works perfect both with Orca and Creality Slicer.

No issues after the update.

I just updated the firmware on my K2 pro

and so far is working real good

I only get that message on my k2 pro if I get a stl or 3mf file from another source and some of the code isn’t the same in which case Creality slicer usually inputs it’s equivalent code and omits what it doesn’t have which usually relates to the infill I’ve noticed so far. Accepting and modifying the infill to what you prefer has yielded satisfactory end results.
