it seems to me there is no official firmware to combo “K1C + CFS + Upgrade Kit”, i am right?
My K1C frequently has its screen “lock” after print something. To this the only solution is to turn off and on. Or simply ignore the issue and send commands using only PC or Mobile App.
And even if i look into printer software looking for firmware upgrades, always is the same message “you are using the latest firmware version”.
I’m struggling with exactly the same issue. I’m really not sure spending money on CFS is good idea. It causes too much trouble.
I am also having all kinds of issues with this upgrade as I replaced so many parts as I purchased a second kit without the spool case.. but I get rid of one issue to only get another.. the biggest issue is when a part is using more then one color, it slows down feeding the filament. I tried everything to fix it, but not going well. And now the filament gets clogged in the hot end and has to be taken apart and cleaned out manually, to just clog up again.. as this is the newest unicorn hot end.. Any help would be appreciated?
I’m seriously considering to get rid of K1C and divorce from Creality at all. The whole CFS thing is not working with Orca Slicer. I really hate Creality Print, it is extremely buggy and user unfriendly.
This week I found that the Firmware that was shipped with the CFS Upgrade was probably not the right one for my K1C, which has main board version CR4CU220812S12.
I was checking the official firmware page ( Flagship Series Firmware Download | Creality 3D Printer Firmwares ) and I notice a newer firmware for my main board model: CR4CU220812S12_ota_X2000E_V1.1.0.27.20251225.img
However I am currently running the latest firmware that was provided by Creality: v2.3.5.34 and the file name is: CR4CU220812S11_ota_img_V2.3.5.34.img
Which means that this firmware is for a older main board version. Not sure if that could be the root cause of some of the issues.
Anyway, I copied the latest firmware for my mainboard to a pen drive to try updating it. And guess what?
My K1C is not detecting new firmwares via pendrive…
Now I am not sure if this is an issue with my printer or with the current firmware or because there is some sort of version checking that prevents it to be installed since the most recent one for my main board has a smaller version then the firmware I currently have.
Does anyone knows? And how can I force the installation of the new firmaware using pen drive?
HI @jgesser were you able to solve your problem? I’m in exactly the same boat - I’m hoping getting the right OTA file to load might help with layer shift.
Still in the same place, I have contacted Creality support, they told me that the firmware CR4CU220812S11_ota_img_V2.3.5.34.img was the latest compatible with my printer and they had no plans to fix the issue with layers counting twice since it was a minor issue.
I also have issue with the bed temperature when printing ABS right after had finished printing something else using ABS, the printer waits until the bed cools down to 50 degrees celcius, so I have to wait a lot of time. And it starts printing before the bed reaches 100 degrees, which causes problem with adhesion.
Anyway, still suffering with same issues.
versão do firmware correto (segundo o suporte creality): CR4CU220812S11_ota_img_V2.3.5.34.img
The response i received from CS, Dear Customer
“Hello! Your request has been updated. To add additional comments, please reply to this email. You also can click Creality Wiki to learn more: https://wiki.creality.com/en/home (Official Knowledge Sharing Platform).
We fully understand your concerns and frustration. This is currently related to the firmware design, not a hardware issue with the printer. We will urge the R&D team to look into it, as this is not a hardware problem at this time.”
So much for stellar support, they have already moved on to the K3, which means eventually they won’t support the K2 eventually
I wonder if there will be more support for the K1C. I bought it last year and added the CFS, but the CFS version is stuck on firmware 1.1.3 and it fails constantly. I know there have been updates, but not for the K1C. It’s honestly so frustrating how they release a new K1C 2025 and just leave the previous one forgotten. At this point, I regret investing in the CFS and this printer.
