Reading and Checking the Mainboard ID

Note

• This tutorial describes how to read and check the ID of a mainboard.

Notes

Note

• Make sure the motherboard has flashed the USB firmware before operating;
• This tutorial is only applicable for searching the Motherboard ID, not for Toolboard ID;
• Please ensure the host computer is properly connected to the motherboard before proceeding;
• For instructions on viewing the Toolboard ID, please refer to the relevant product documentation.

Connect to SSH

• Please log in to SSH via the network first
• Please ensure you are logging in to SSH via the network, not via serial port

Search for Device

• Please ensure the host computer is connected to the Internet and that the data cable connecting the device to the host computer supports data transfer.
• After SSH connecting to the host computer, enter lsusb and press Enter. If you see the information circled in the image below, you can proceed to the next step.
  • If no information is displayed, this indicates a system issue with the host computer. We cannot assist with this, and you will need to replace the system with a confirmed working one or change the host computer.
  • If the lsusb command is not found, install it by running the following command:

    sudo apt-get install usbutils

    
• 1d50:614e is the device you will use in this process.
  • Some host computers may fail to fully display or not display the information due to system issues.
  • If the device is shown after running the lsusb command but 1d50:614e is missing, try using a different data cable or connect the main board to another USB port on the host computer.

Note

You must proceed to the next step only after one of the 1d50:614e devices is found.

Search for USB ID

ls /dev/serial/by-id/*

• Enter the command below and press Enter. If everything works properly, a blue ID line like the one below will appear. (The example below is for reference only)

• If no ID appears after entering the command, but the device shows up in lsusb, please try using a different host computer or operating system

Note

If multiple IDs appear, please choose the corresponding ID based on your motherboard's MCU model.

Fill in the USB ID into the Configuration

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

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

Note: All IDs shown in this document are examples. The actual ID varies for each motherboard. Please modify and fill in based on the ID you obtained.

Fill in the USB ID

• Locate [mcu] and replace it

Note

• In the configuration file, replace:

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

• Reference examples

Example for fluidd

Example for mainsail

• Click SAVE & RESTART in the upper right corner. It will automatically save and restart klipper
