  cd ~/klipper && rm -rf ~/klipper/.config && rm -rf ~/klipper/out && make menuconfig

• Where rm -rf ~/klipper/.config && rm -rf ~/klipper/out is to delete previous compilation data and firmware, make menuconfig is to compile the firmware, after execution, the following interface should appear

  

• Select Enable extra low-level configuration options and press Enter

  

• Enter the menu Micro-controller Architecture then select STMicroelectronics STM32 and press Enter

  

• Enter the menu Processor model, select STM32H723 and press Enter

  

• Select Bootloader offset, select: 128KiB bootloader

  

• Select Clock Reference (8 MHz crystal), select: 25 MHz crystal

  

• Communication interface, select: USB (on PA11/PA12)

  

• Press the Q key, and then press Y key when Save configuration appears

Search for USB ID

1. Open the browser and enter the IP address of the host computer in the address bar. For example, if my host computer's IP is 192.168.101.179, directly type it in and press Enter.

2. Open the host computer's web interface and locate the following configuration options in the left sidebar:

For fluidd: {…}, click into it and you can find printer.cfg

For mainsail: Machine, click into it and you can find printer.cfg

3. After clicking into printer.cfg, click on DEVICES in the top right corner.

4. Click SERIAL and then refresh:

   Refresh for fluidd

   Refresh for mainsail

5. Copy the ID; click the arrow to copy:

   Check if ttyAMC exists in fluidd, and ensure that Path by ID exists; this is the USB ID

   Check if ttyAMC exists in mainsail, and ensure that Path by ID exists; this is the USB ID

Fill in the USB ID

1. Close DEVICES and fill in the ID

   Note

   • Please change the following in the configuration file:

   [mcu] 
   serial: /tmp/klipper_host_mcu

   to

   [mcu host] 
   serial: /tmp/klipper_host_mcu

   • Add:

   [mcu]
   serial: <Replace this with the ID you just found>

   In fluidd, locate [MCU]

   In mainsail, locate [MCU]

2. Fill the ID into the configuration.

   tip

   • After entering the ID, click SAVE & RESTART in the top right corner.

3. If Klipper displays a warning ADC out of range, this is normal. Connect the heated bed and thermistor to the mainboard, configure the thermistor pins for the nozzle and heated bed, then save and restart.

dangerous

Note: All IDs shown in this document are examples. Each mainboard has a unique ID; please use the actual ID you obtained.
