Hey @jokubasver , great job!
Thanks alot for your work and for sharting it with us.

I got one question: Can I use the original firmware PID and e-steps values? Or should I install your firmware, get new values and then only flash the personalized version with my values?

Just flash the pre-compiled firmware and then calibrate PID and e-steps. Editing these values in the source code is not necessary - adding the values in firmware just adds a piece of mind that if your EEPROM was ever cleared - your personal calibrated values will not disappear.

All calibration can be done via USB using Octoprint or Pronterface. PID can be calibrated on the printer itself using the screen. I'm not running Marlin on my Kobra Neo anymore, switched to Klipper, but I think my changes in the firmware allow you to change the e-step values on the screen as well, so it might be possible to do everything via the screen - without Octoprint or Pronterface.

Of course you can choose to not touch those values and just use the factory or my own personal values, but your print quality might suffer a bit because of this.
