Update - 1/20/2015

As I stated earlier the Intel DMUD board is not a good fit for CNC use.

That said, I ordered and received a new mini-ITX board. It's an ASRock D1800B-ITX board.

So far so good.  It does not seem to suffer from any of port driver problems and I have run several jobs without errors.

The board has several advantage over the previous board I was using.

  1. It's faster (2.5Ghz)
  2. Supports VGA and HDMI ports
  3. Includes system monitoring software
  4. Has both USB 2 and USB 3 ports
  5. Looks to be a well stocked board
  6. It costs less
  7. !! It Works !!

While preliminary tests show that board is a good CNC PC fit, I will be doing much more testing. 

So far it can use the same support componets to get the board up and running. Even the tiny plug-in PSU is working fine.



In this series I will show you what I do to build a dedicated CNC PC. I will provide links to components I have tested and take you through my build process.


In the following photos I show the Intel DMUD board. I no longer recommend this board. Use the ASRock board instead. (shown above)


Please keep in mind the computer components are a constantly in flux.  Boards that I have tested a year ago are no longer available today.


The mini ITX board shown here is a good example of the PC component supply flux.  This AMD board was my board of choice until recently. It is now no longer available.


I compiled a complete set of components that I have tested.  They can be found here.

Test Assembly

Let's take a look at a basic test assembly. Note that the CPU comes with the board and is already installed.

Attach power supply and adapter

Install monitor.  Note that you may need an adapter to connect to a HDMI port.

Install Memory.

Install power switch, reset switch, power LED, and hard drive LED.

Install WiFi adapter and keyboard. Note that this keyboard has touch pad for mouse input.

The Wifi adapter will provide internet access so you can perform updates to your OS. The board has wired LAN connector so you can use that instead if you wish.

Install solid state hard drive.

You will need a temporary DVD drive so you can install Windows. You will also need a copy of Windows.  Currently I prefer Windows 7 as my CNC OS.



Once your test machine is complete and you have installed Windows, you will want to start looking for an enclosure. One of the reasons I like using a mini ITX form factor and mini PSU, is so that I can install the board just about anywhere.

Here I have installed the board in the base I created for the KRmf70 micro CNC.


One of My Builds

Testing is going well, I have used this CNC PC to control my KRmc01, KRmf70, and KRMx02 machines.

This is a little plastic enclosure that I built. It is small enough to keep out of site if need be.
