Search USB Tutorial

Precautions Before Searching for Devices

• Please connect to SSH before searching for the USB ID Connect to SSH
• Please note that you need to ensure that you log in to SSH via the network rather than via serial port
• Please ensure that the mainboard with the flashed USB firmware is connected, and the data cable connecting to the host computer has data transmission function

Search for Devices

• Ensure that the host computer can connect normally to the network, and ensure that the data cable connecting the downstream device to the host computer has data transmission function.
• After SSH connection to the host computer, 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 feedback at all, this is a system problem with the host computer. We are unable to help. You need to replace it with a confirmed normal system or replace the host computer.
  • If the prompt says there is no lsusb command, you can execute the following command to install:

    sudo apt-get install usbutils

    
• 1d50:6177 belongs to the device you will use this time.
  • Some host computers may not display fully or not display due to system issues.
  • If the lsusb command can display the device but does not show 1d50:6177, please try replacing the data cable and connecting the mainboard to another USB port on the host computer.
• If you have executed the above steps before and successfully burned the Klipper firmware, the mainboard is running normally, and you just need to update the Klipper firmware, please directly refer to the Firmware Update section in the right-hand menu bar of this page.

Note

You must query the 1d50:6177 device before proceeding to the next step

Search for USBID

ls /dev/serial/by-id/*

• Enter the command below and press Enter. If everything is normal, one blue ID will appear. (The following is for reference only)

• If no ID appears after entering the command below, but lsusb shows the device, please replace the host computer or the host computer system.

Note

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

Fill in the USB ID into the configuration

• Open the printer web interface, find printer.cfg under the configuration option in the left sidebar: fluidd is {...}, mainsail is Machine, click to enter.

  

• Copy the blue ID and paste it into the serial: field under the [mcu] node in the printer.cfg configuration file. 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 thermistor properly, configure the thermistor and output pins for the nozzle and heated bed, then save and restart.
