Profile for Creality K2Pro (OrcaSlicer) for PLA.

I wasn’t satisfied with the results using the stock Creality profile, so after dozens of hours of calibration, I’ve implemented my own tweaks. The print quality has significantly improved.

I have also switched from CrealityPrint to OrcaSlicer (v2.3.1) because it offers a much wider range of settings and control.

Important: This profile is intended for firmware version CR0CN200400C10_ota_img_V1.1.3.6 and later. If you are on an older version, you must manually disable "Arc Fitting" as it is not supported. Also, this is designed specifically for high-flow nozzles.

Make sure to perform a thorough manual calibration of your K2 Pro (Temperature, Bed Level, Flow Rate, and Pressure Advance). I strongly advise against relying on automated calibration, as it lacks the necessary precision.

You can use these settings as a baseline, but keep in mind that you’ll need to fine-tune them based on your specific nozzle, ambient room temperature, filament type, and even the pigment (color) of the plastic. All of these factors affect the final result.

For the test that you see in the photo, I used a 2 cm high model:

I will continue to update this profile as I find further optimizations.

When printing large parts, plastic bumps formed on the first layers. The problem has been fixed and a number of edits have been made.

//19.03.2026//
An error was found with an incorrect parameter for the internal bridge (overhang).

//20.03.2026//
Added support for 0.24 mm

//28.03.2026//
Added Fuzzy Skin profile

I've changed the command in the start G-code from M104 S to M109 S. Previously, the nozzle purge temperature (220°C) wouldn't switch to the print temperature set in the slicer (210°C). With this fix, the printer now waits to reach the target temperature and prints at the required 210°C.

There is also a profile for PETG:
