  • Please prepare a data cable with data transmission capability. If the length is particularly long, it is recommended to use a cable with a magnetic ring.

    Precautions Before Searching for Devices​

    • Before searching for the USB ID, please first connect to SSH
    • Please make sure you are logging in via network SSH rather than serial port SSH
    • Please ensure that the motherboard with the USB firmware installed is properly connected, and the data cable connecting it to the host computer has data transfer capability

    Search for Devices​

    • Now that you have successfully logged into the host machine, you can enter lsusb to search for devices. You will encounter one of the following scenarios:
      • If entering lsusb prompts that the ls command is not found, you can enter the following command to install the command: 
        sudo apt-get install usbutils
      • If entering lsusb produces no response, this indicates a system issue beyond our control. You need to change the system or use a confirmed working system.
      • If you see the information shown in the image below, note that this is just a reference. You only need to confirm the characters after the ID.
    • 1d50:614e belongs to the device you will be using. Ignore the rest of the prompt as the system issue may cause it to display incompletely or not at all.
    • If none of the above occur, please check if the data cable is properly connected and if the firmware is correctly installed.
    Note

    You can only search for the USB ID when you have 1d50:614e.

    Search for USB ID​

    ls /dev/serial/by-id/*
    • Enter the command below and press Enter. If everything is normal, a blue ID will appear (the one below is just an example).
    • If no ID appears after entering the command below, but lsusb shows devices, try changing the host machine or the host machine's system.
    Note

    If multiple IDs appear, select the appropriate one based on your motherboard's MCU model.

    Fill in the USB ID in the Configuration​

    • Open the printer web interface, find the configuration option in the left sidebar: for fluidd, it is {...}; for mainsail, it is machine, and click to access printer.cfg.

    • Copy the blue ID and fill it into the [mcu] section of the serial: parameter in the printer.cfg configuration file. Save and restart to connect to the motherboard. If Klipper displays ADC out of range, it is normal. Connect the bed and thermistor properly, configure the hotend and bed thermistor and output pins, then save and restart.

    Note: All IDs mentioned in the document are examples. The actual ID for each motherboard is unique. Please modify according to the actual ID obtained.
