If you would like to study or compile the BMCU source code, we recommend using Visual Studio Code with the PlatformIO extension.
The recommended folder structure is as follows:
BMCU/
├── platformio.ini
└── src/
├── main.cpp
├── main.h
├── motor_control.cpp
├── motor_control.h
└── ..............
📄 platformio.ini Example

The BMCU and AMS interfaces are illustrated in the figure below.
The Original AMS Lite comes with an interface that mirrors the AB signal cable, so you cannot use the original AMS cable from Bambulab to connect the BMCU to the printer.
