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 would be your recommendation for "power supply 2 (24vdc)" connecting to USB motion card? Are there any videos explaining it's connection to the relay coil? (not quite sure what relay coil is)

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.

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

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.

Any of the following power supplies will be fine for powering the Mach3 USB controller:

Yes, you can add a relay to the Mach3 USB controller. The relay must be a 24V relay on it's input side and be able to be set to active low. I demonstrate this in a video on the following page:

The Mach3 usb controller/interface has instructions and videos on this page:

There is a 5 step process on that page to install the plug-in and the configuration xml file that is necessary for the proper functioning of the controller.

The videos on that page also demonstrate in detail how to install the software, plug-ins, xml file and wiring and testing most of the features of the Mach3 USB interface.

Hope this helps.

Hi. The relay that we sell here:
https://www.buildyourcnc.com/item/electronicsAndMotors-breakout-Relays-relay-board-250V-12A-5V

Has the same relay as the parallel breakout board:
https://www.buildyourcnc.com/item/electronicsAndMotors-parallel-breakout-relay

And contains three terminals: "S", "P" and "P". The "P" is always connected and will be the connection between the "S" or the "O" depending on if you need the connection to be Normally Closed (NC) or Normally Open (NO).

- Use the "O" if you need the connection from "P" and "O" to be Normally Open, meaning that the circuit will close (be connected) if the relay engages.

- Use the "S" if you need the connection from "P" and "S" to be Normally Closed, meaning that the circuit will open (be disconnected) if the relay engages.

Yes, Mach3 (the software profram) will work with Windows 7, and windows 10 when coupled with the Mach3 USB interface. If you intend to use the parallel port driver, stick with Windows 7 in 32-bit mode.

Additional Information:
Rnrmotion.dll is a dynamic link library which is very similar in function to an executable program, or app. Since a dll is executable, malicious code can be embedded in that type of file, so windows will automatically flag all files of this type. You just need to make sure you are downloading from a trusted source. The emotion.dll file on our site is clean, but still run run windows defender against it to make sure.

You can use any of the inputs on the mach3 controller. If there is a free terminal input terminal, use that one. You will need to modify the input number in the inputs tab in config->Ports&pins to assign the limit to the correct input number. When adding the pin number, make sure that the port number is 3.
