Recently i had to recompile for the Creality* Ender 3v2 (not NEO!) a new Klipper firmware based off the Klipper  0.11.

As per the instructions of the installation of Klipper you will have to flash the microcontroller as follows:

cd ~/klipper/
make menuconfig

During “make menuconfig” select the following settings:

  • Enable extra low-level configuration options
  • Micro-controller Architecture (STMicroelectronics STM32)
  • Processor model (STM32F103)
  • Bootloader offset: (28KiB bootloader)
  • Communication Interface: (Serial (on USART1 PA10/PA9))


Once you have compiled the firmware using make you can flash it by copying the file out/klipper.bin to a SD card and turning on the printer with the card inserted. The firmware filename must end in “.bin” and must not match the last filename that was flashed.
