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​

Important Notes​

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, you must ensure its GND is connected to the mainboard's GND (sharing the same 24V/12V power supply will achieve this).

RS232 Notes​

  • Besides the D8, D8PRO, and C8P, which support the RS232 interface, other mainboards do not support the RS232 interface.
  • For unsupported mainboards, you need to use a G2T or UTOR for connection.

Searching for the RS232 ID​

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

  1. Open the host's WEB interface, and find the following in the configuration options on the left sidebar:
  • For fluidd: {…}, click to enter, then find printer.cfg.
Loading...
  • For mainsail: Machine, click to enter, then find printer.cfg.

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

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

  • Refreshing in mainsail.

  1. Copy the ID. Click where the arrow points to copy.
  • In fluidd, check if ch341-uart exists, then click Path_by_hardware. This is the RS232_ID.
Loading...
  • In mainsail, check if CH341-UART exists, then click Path_by_hardware. This is the RS232_ID.

Notes
  • When using UTOR to connect the toolboard, two RS232_IDs often appear. Please try them one by one.

Filling in the Toolboard RS232 ID​

  • Below is a reference configuration.

    Notes
    • 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
    • Adding the toolboard ID must be [mcu toolboard] followed by serial: and then the toolboard ID you searched for.
    • Below is a reference configuration.
    • Please note this tutorial is for toolboard ID search and configuration. Normally, it is already properly connected to the mainboard.
    • The mainboard must be [mcu], and the toolboard is [mcu toolboard].
    • Click SAVE & RESTART in the upper right corner. Clicking will automatically save and restart Klipper.

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