USB Firmware Compilation

Check DIP Switch

Note

• When in normal use, please set the DIP switch to the up position
• When switching the DIP switch, please push it all the way up, otherwise it may fail to connect to the lower-level machine!!!

SSH Connection to Host Machine

Warning

• Before compiling the firmware, you need to use WiFi to connect to the host machine via SSH

• First, please: Use WiFi to connect to the host machine SSH

USB Firmware Burning

Tip

• A pre-compiled USB firmware is available in the FLYOS-FAST system, so there is no need to manually compile the firmware; just execute the command below to burn it.
• Alternatively, you can choose to manually compile the USB firmware and compile the firmware yourself.

• Enter the following command through SSH connection to the host machine

fly-flash -d c5 -h -f /usr/lib/firmware/klipper-h723-128k-usb.bin

Klipper固件编译和配置页面操作说明

tip

请确保键盘输入法为半角模式，即英文模式

1. 键盘上键↑，下键↓，用于上下移动光标来选中菜单项
2. 确认键Enter 或 空格键Space，用于勾选菜单或进入子菜单
3. 退出键ESC，用于返回上一级菜单
4. Q键，用于退出Klipper固件配置页面
5. Y键，在退出Klipper固件配置页面时，如果有提示，则点击Y键保存配置文件

warning

如果配置页面选项比较少，请先勾选[ ] Enable extra low-level configuration options，用于显示部分隐藏选项

Below is an introduction on how to compile the firmware:

• After connecting to SSH, enter the following command and press Enter:

  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 Q key, a Save configuration prompt will appear, then press Y key

• Now the configuration should be saved, and you should have returned to the command line interface

• Enter the following command to start compiling, this process takes some time

make -j4

• Finally, if the output is as follows, the compilation is successful

tip

Execute the following command to burn the firmware

fly-flash -d c5 -h -f ~/klipper/out/klipper.bin

Search for USB ID

1. Open the browser and enter the IP address of the host computer in the address bar, for example, if the IP address of my host computer is 192.168.101.179, simply enter it and press Enter.

2. Open the WEB interface of the host computer, find in the configuration options on the left sidebar:

For fluidd: {…}, click to enter, you can find printer.cfg

For mainsail: Machine, click to enter, you can find printer.cfg

3. Click into printer.cfg, then click DEVICES on the top right

4. Click SERIAL, then refresh

Refresh for fluidd

Refresh for mainsail

5. Copy the ID, click the arrow to copy

For fluidd, check whether ttyAMC exists and ensure Path by ID exists, this is the USBID

For mainsail, check whether ttyAMC exists and ensure Path by ID exists, this is the USBID

Fill in USB ID

1. Close DEVICES and fill in the ID

Note

• Please modify the configuration file as follows:

[mcu] 
serial: /tmp/klipper_host_mcu

to

[mcu host] 
serial: /tmp/klipper_host_mcu

• Add:

[mcu]
serial: <replace with the ID you just queried>

Find [MCU] in fluidd

Find [MCU] in mainsail

2. Fill in the ID in the configuration

tip

• After filling in the ID, click SAVE & RESTART on the top right

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

dangerous

Note: All IDs mentioned in the document are examples. Each motherboard has a different ID, please fill in the actual obtained ID.
