Flashing Firmware

When using any MCU with Klipper, it is important to first flash Klipper firmware. Follow these steps to flash your MCU with Klipper firmware:

Important

For MCU's using CANbus, follow this guide.

1. SSH (PuTTy) into your Raspberry Pi

2. Run the following commands:

   cd ~/klipper
   make menuconfig
   

3. Enter your MCU board's firmware settings, as explained later in this page.

4. Save (Q)

5. Run the following command:

   make flash FLASH_DEVICE=/dev/serial/by-id/<your-mcu-id>
   

Tip

To find your serial port, open a new SSH window, unplug your controller board, and run:

 ls /dev/serial/by-id

Next, plug in your controller board, and re-run the command. The newly added line is your controller's serial address.
