Reading and Viewing Motherboard ID

Precautions Before Searching for Devices​

  • Before starting to get the ID, please first connect to SSH
  • Please ensure that the data cable connecting the lower-level machine to the upper-level machine has data transmission capabilities
  • After connecting to the upper-level machine via SSH, enter lsusb and press Enter. Several devices may appear as follows:
  • If the system does not support lsusb, you can execute the following command to install it:
sudo apt-get install usbutils
  • Please confirm whether the motherboard firmware has been correctly flashed.
  • If it is a USB firmware, 1d50:614e should appear after lsusb.
  • If it is a USB bridge CAN firmware, 1d50:606f should appear after lsusb.
  • If it is RS232, it needs to be paired with UTOR or G2T. G2T does not require searching for firmware, while UTOR should appear 1a86:7523 after lsusb.

Precautions While Searching for Devices​

Note

Search ID commands cannot be mixed!

  • Please note that USB firmware can only use the USB ID search method.
  • Please note that USB bridge CAN firmware can only use the CAN ID search method.
  • Please note that RS232 firmware can only use the RS232 ID search method.
  • If 0483:df11 appears, it may be due to the firmware being flashed but the motherboard not being powered off and restarted. If the motherboard remains unchanged after power-off and re-power-on, please check if DFU (jumpers/dip switches/buttons) has been disconnected.
  • If 2e8a:0003 appears, it may indicate that the wrong firmware was flashed. Please note that RP2040 can only flash UF2 firmware compiled, not other types of firmware. After 2e8a:0003 appears, disconnect BOOT (jumpers/dip switches/buttons) to avoid flashing failure!!!
  • The UF2 firmware for RP2040 is compiled with No bootloader selected during compilation.

Precautions before searching for devices​

  • Before searching for the USB ID, please first connect to SSH
  • Please note that it is necessary to ensure that the SSH is logged in using the network rather than the serial port.
  • Please ensure that the motherboard with the USB firmware flashed is connected, and ensure that the data cable connecting the upper computer has a data transmission function.

Search for devices​

  • Please ensure that the upper computer can be connected to the network normally, and ensure that the data cable connecting the lower computer to the upper computer has a data transmission function.
  • After connecting to the upper computer via SSH, enter lsusb and press Enter. If the information circled in the image below appears, you can proceed to the next step.
    • If there is no information feedback, this is a system problem of the upper computer, and we are powerless. You need to replace the system with a confirmed normal one or replace the upper computer.
    • If the lsusb command is not found, you can execute this command to install it: 
      sudo apt-get install usbutils
  • 1d50:6177 is the device you need to use this time. The suffix OpenMoko, Inc. stm32f407xx has a certain reference value, but it is not used as a judgment basis.
    • Some upper computers may have incomplete or no display due to system problems.
    • If the lsusb command can display the device, but there is no 1d50:6177, please try to change the data cable and try to connect the motherboard to other USB ports of the upper computer.
  • If you have previously performed the above steps and successfully burned the Klipper firmware, and the motherboard is operating normally, but only need to update the Klipper firmware, please directly view the Firmware Update chapter in the right sidebar of this page.
Precautions

The next step can only be performed after the 1d50:6177 device is found.

Search for USBID​

ls /dev/serial/by-id/*
  • Enter the following command and press Enter. If everything is normal, a blue ID will appear in the following line. (The following is just for reference)
  • If there is no ID after entering the following command, but there is a device in lsusb, please replace the upper computer or the upper computer system.
Precautions

If multiple IDs appear, please select the corresponding ID according to the MCU model of your motherboard.

Fill in the USB ID in the configuration​

  • Open the printer web interface, find in the configuration options on the left sidebar: for fluidd: {…}; for mainsail: Machine, click to enter, and you can find printer.cfg.

  • Copy the blue ID and fill it in the serial: of the [mcu] node in the printer.cfg configuration. After saving and restarting, the motherboard can be connected. If Klipper prompts ADC out of range, it is a normal phenomenon. Connect the heated bed and the thermistor, configure the thermistor pins and output pins of the nozzle and the heated bed, and then save and restart.

Note: All IDs appearing in the document are examples. The actual ID of each motherboard is different. Please modify and fill in according to the ID actually obtained.
