Jacobean's K2 Plus firmware
A complete alternative firmware stack for the Creality K2 Plus.
It includes a custom Linux system and my Kalico fork, with ground-up implementations of CFS control, closed-loop motor control, power-loss recovery, and other K2-specific systems.
The stock firmware remains available after installation. You can switch between stock and custom whenever you want without reinstalling either one. Each keeps its own configuration and files.
To install it, follow the installation guide.
