232 Wiring Diagram​

  • Before searching for the ID, connect the tool board to UTOR using an XT30 data cable. The reference wiring diagram is shown below.

Searching for the RS232 ID of the Toolboard​

Precautions​

Important Preparations
  1. Firmware Requirement:
    The toolboard must be flashed with the RS232 firmware, otherwise communication will not be possible.
  2. Mandatory Common Ground:
    ⚠️ Before connecting the toolboard, ensure its GND is connected to the mainboard's GND (using the same 24V/12V power supply achieves this).

RS232 Notes​

  • Only the D8, D8PRO, and C8P mainboards support the RS232 interface. Other mainboards do not.
  • For unsupported mainboards, use G2T or UTOR for connection.

Searching for the RS232 ID​

  1. Open a browser, enter the host's IP address in the address bar (e.g., if the host IP is 192.168.101.179, enter it and press Enter).

  1. Open the host's WEB interface. In the left sidebar configuration options, find:
  • For fluidd: {…}. Click to find printer.cfg.
Loading...
  • For mainsail: Machine. Click to find printer.cfg.

  1. Click printer.cfg, then click DEVICES in the top right corner.

  1. Click SERIAL, then refresh.
  • Refreshing in fluidd.

  1. Copy the ID. Click the indicated arrow to copy.
  • In fluidd, check if ch341-uart exists, then click Path_by_hardware. This is the RS232_ID.

  • In mainsail, check if CH341-UART exists, then click Path_by_hardware. This is the RS232_ID.

Note
  • When connecting the toolboard using UTOR, two RS232_IDs often appear. Try each one.

Configuring the Toolboard RS232 ID​

  • Below is a reference configuration.

    Note
    • In the configuration below, toolboard refers to the toolboard name. If it has a different name, replace it accordingly.
    dangerous
    [mcu toolboard]
    serial: <Replace here with the ID you just queried>
    baud: 250000
    restart_method: command
    • When adding the toolboard ID, it must be [mcu toolboard], followed by serial:, and then the toolboard ID you found.
    • Below is the reference configuration.
    • Please note this tutorial is for toolboard ID search and configuration. Normally, the toolboard should already be properly connected to the mainboard.
    • The mainboard is always [mcu], and the toolboard is [mcu toolboard].
    • Click SAVE & RESTART in the top right corner. This will automatically save and restart Klipper.

Note: All IDs appearing in this document are examples. The actual ID for each mainboard is different. Please use the ID you actually obtained. ::​
