Installation

Install Klipper, Moonraker, and Fluidd on the Raspberry Pi by following the KIAUH installation instructions.

Flash the controller firmware

The initial Klipper firmware installation on the BIGTREETECH SKR 1.4 Turbo must be performed with a microSD card.

1. SSH into the Raspberry Pi and configure the firmware build:

   cd ~/klipper
   make menuconfig

   Select these options:

   • Micro-controller Architecture: LPC176x
   • Processor model: lpc1769 (120 MHz)
   • Bootloader offset: 16KiB bootloader
   • Communication interface: USB

2. Compile the firmware:

   make

3. Insert a FAT32-formatted microSD card into your computer. From the computer, copy the compiled firmware from the Raspberry Pi directly to the card, renaming it to firmware.bin:

   scp your-user@raspberrypi.local:~/klipper/out/klipper.bin \
     /path/to/mounted-microSD/firmware.bin

   Replace the SSH user, Raspberry Pi hostname, and microSD mount path as needed.

4. Power off the printer and disconnect its USB cable. Insert the microSD card into the SKR board, then power the printer on. The board flashes the firmware during startup and renames the file to FIRMWARE.CUR when successful.

5. Power the printer off, remove the microSD card, reconnect USB, and power it back on.
