  • Optimize the information prompted by the indicator light:

    • When the controller is in idle state, the red LED will blink when opening the door.

    • When the controller is receiving a file, the yellow LED will blink.

  • Optimize the processing flow of exceptions:

    • If SD card is not detected or the specified file cannot be opened, the user will be prompted by buzzer and indicator.

    • When the controller recovers from the abnormal state, it will reset the system coordinates so that the toolhead will work from user’s expected position.

  • Optimize the button handling logic, now the button is only responsible for startup work:

    • Short press: try to start running boundary.
