Search Toolboard RS232 ID​

Precautions​

Important Preparation
  1. Firmware Requirements:
    The toolboard must be flashed with RS232 firmware, otherwise communication is not possible.
  2. Mandatory Common Ground:
    ⚠️ Before connecting the toolboard, ensure that the toolboard and the motherboard share the same GND (using the same 24V/12V power supply is sufficient).

RS232 Precautions​

  • Except for D8, D8PRO, and C8P, which support the RS232 interface, other motherboards do not support the RS232 interface.
  • Motherboards that do not support RS232 need to use G2T or UTOR for connection.

Search for RS232 ID​

  1. Open a browser and enter the IP address of the host computer in the address bar. For example, if my host computer IP is 192.168.101.179, simply enter it and press Enter.

  1. Open the WEB interface of the host computer. In the configuration options on the left sidebar, find:
  • For fluidd: {…} , click it to find printer.cfg
Loading...
  • For mainsail: Machine, click it to find printer.cfg

  1. Copy the ID by clicking the arrow indicated.
  • In fluidd, confirm if ch341-uart exists, then click Path_by_hardware. This is the RS232_ID.

Note
  • When using UTOR to connect the toolboard, there are usually two RS232_IDs. Try each one.

Fill in the Toolboard RS232 ID​

  • Below is a reference configuration.

    Note
    • In the configuration below, toolboard refers to the toolboard name. If you have a different name, replace it accordingly.
    Danger
    [mcu toolboard]
    serial: <Replace here with the ID you just found>
    baud: 250000
    restart_method: command
    • To add the toolboard's ID, it must be [mcu toolboard] followed by serial: and the toolboard ID you found.
    • Below is a reference configuration.
    • Please note that this tutorial is for searching and configuring the toolboard ID. Normally, the toolboard should already be properly connected to the motherboard.
    • The motherboard must be [mcu], and the toolboard must be [mcu toolboard].
    • Click SAVE & RESTART in the upper right corner to automatically save and restart Klipper.
