Question #: 14267

Question: What Relay do I need for the Mach3 usb motion card?

Current Solution

You will need a 24V DC Solid State Relay to accompany the Mach3 USB Motion Card as the outputs on that motion card requires a 24V Power Supply.

Until we start supplying this relay, you can find these relays here:

  • What is the relay coil on the USB motion card for?

    A 24V connection to the USB motion card is only needed if you are using limit switches (inputs), powering the spindle/VFD speed and direction, and for the outputs, for powering other devices (mist, coolant, etc.).

    If you are using a VFD (Variable Frequency Drive, also called Inverter) for a spindle, they typically have a 24V out terminal that can be used with our USB motion card. If you are not using a spindle/VFD (we highly recommend one), then you will need to purchase a 24v power supply to power that side of the board.

    The outputs mentioned above are to connect to external devices and will require a relay (a mechanical switch that is controlled by a digital signal). This mechanical switch can turn on a device like coolant and mist, or even a router, if you are using one. A relay is required to turn on these devices because the devices are typically higher voltage, like mains (110v or 220v). So, a relay can turn on or off a high voltage device with a lower voltage (24v) signal.

  • What functionality is lost if 24V power supply not provided to "Mach3 USB Motion Card"?

    If the Mach3 USB does not have a 24V power on the limit switch/output/DAC side of the board, then those functions (limit switches, outputs and the DAC) will not work. If you have a spindle, you can use the 24V output from the VFD (Variable Frequency Drive) to serve as the 24V supply.

  • I have a 64 bit operating system and the Mach3 usb control board. What do i need to communicate between the two?

    You will need a USB cable to connect the computer and the Mach3 USB. The 64-bit operating system must be Windows and you will need the Mach3 CNC control software installed on the operating system.

    You will need to install the USB driver called RNRMotion.dll. You can find the driver here: https://www.buildyourcnc.com/item/electronicsAndMotors-electronic-component-breakout-Mach3-USB-Board

    Move the file to your Mach3 Plugins folder Example: "C:/Users/ProgramFiles/Mach3/Plugins"

    Mach3 will prompt you to select a driver and this is where you can select the "RnRMotionController" and check "Don't ask me again". This will allow your board to communicate with Mach3.

    You will also need the xml file found on this page: https://www.buildyourcnc.com/item/electronicsAndMotors-electronic-component-breakout-Mach3-USB-Board

    On that page, you will need to download the XML Mach3 Config File by right clicking on the link and selecting "save as". Save the Mach3Mill.xml file in your Mach3 root folder.

    That file is the main configuration file for the Mach3 board. It has all of the typical settings that the Mach3 board needs.

  • the tutorial for the discontinued usb card is great but i have your usb motion card stb4100 i need with AD AP +5v wired to the cp+cp-cw+and the cw-

    The connections for the Mach3 USB CNC Machine interface card you refer to is connected as follows:
    - All of the "D" connections such as XD, YD, ZD and AD are the direction connections and are connected to the CW- connections on the drivers.
    - All of the "P" connections such as XP, YP, ZP and AP are the pulse connections are are connected to the CP- connections on the drivers.
    - The 5V connections on the USB board are connected to the CP+ and CW+

  • The mach3 USB card requires 24V, how do I supply this?

    If you are using a spindle with a VFD, there is a 24 volt power supply that will provide the correct power for the V+ and V- on the Mach3 USB. The 12V option is only if you are using the limit switches on that side of the board, but if you are using it to control spindle speed and for the outputs, it's best to use a 24V power supply, or the 24V output on the VFD.
