How to Build Your Own CNC Router – A 2020 DIY Guide

CNC machines have been around for quite some time and they were first presented to the public all the way back in the 1950s. During that era, these devices basically transformed how we manufacture specific items. They have also helped with various processes, which in return, allowed engineers all over the globe to create products by themselves.

If you are thinking about building your own, DIY CNC router, you might find this article to be quite helpful. The text below is going to feature a guide for making a CNC router, as well as some things that you might want to consider before you start your project. Let’s take a closer look at the guide:

What Should I Consider Before Starting The Project?

The most difficult thing that you might come across is determining where you should start. Now, before you start comparing various parts and kits, there are some questions that you should ask yourself first. The questions that you need to answer before starting your project include:

  1. What Will I Make With The Device? – The first thing you should know is that these machines are quite versatile and naturally, they can create various items. But, different types will be better for different things. Hence, you should start by determining what you will make with the CNC tool. By knowing this, you can also learn what pieces you might need to make it.


  1. How Much Time Should I Spend Building it? – The answer to this question will depend on whether you are interested in making this machine for a hobby or profit. Of course, you should spend as much time as you can work on it, but, this is not the only thing to consider. If it is your first time building something like this, you should start smaller and simpler. Hence, you’ll be able to do it properly.


  1. How Much Should I Spend on it? – Similarly to the questions and answers above, it will depend on whether you want to use it for a hobby or a business. Of course, it is always best when you get what you paid for. So, you will need to determine what parts you will need for building your device – and if you do not need something, do not buy it!

A Guide For Building A CNC Machine

You will need a CNC kit is you want to build your machine in an easy and effective way. This happens because the kits come with everything you need to assemble it. Most manufacturers do have optimization features, which means that you can choose the right items that you need.

The Steps You Should Follow When Assembling

  1. Gather The Necessary Components

Of course, the first thing you should do is purchase the necessary parts. The electrical parts that you must get include a processor, stepper drivers & shield, motors, as well as the power supply. Next, choose the mechanical parts such as the tools you will need, the frame, bearing, guides, spacers, washers, nuts, screws, supports, and bolts.

  1. Design How it Will Look Like

By designing the device, you will be able to get a clear picture of how it will look like when it is assembled. You can, for example, start with a sketch and they convert the drawing to CAD by utilizing a program that you feel comfortable with using. This will make everything easier.

  1. Build a Frame

The frame is the most crucial part because it will hold all the parts together. Hence, this is the first thing you should make. Metals such as aluminum are is a good option since they are stable and rigid. Using aluminum can help you boost the longevity of the device, as well as other components.

  1. The Gantry Comes Next

Of course, your machine does not have to feature a gantry, but, it is a quite popular item that people love to add to their DIY CNC device. A gantry is what can allow it to move to the Y-axis, and it will keep it in place above or on your work surface.

  1. Add The Z and the X-axis

The device will move up and down the “Z-axis”, however, you should also have a space that will house the machine. Next, you need to add the bearing and the guide rails which are important parts because they will allow your tool to move up and down the X-axis, which is something that you’’ want it to do.

  1. Add The Drive System And Electrical Parts

Once you are done with the aforementioned things, you will need to make it move. Hence, you should add the drive system, which is usually created from various components, including a motor, pulley, screws, bolts, nuts, as well as the spindles that you will need for your machine.

When you finish with the drive system, it is time to add the electronic parts. Of course, the most important thing is the motor, and then the PSU, rivers, the processor, and the breakout board. Additionally, add the tabletop on, because it will hold the components together. It can be made from basically any material including wood, metal, as well as MDF.
  1. Opt For a Controller And Program

The last thing on your list is the controller and program that you will use. The controller will spread signals that are provided by your computer and processor and then transmits them to signals to the electronic parts. By now, the machine is almost operation. The last thing you should do is choose the program that will make your CNC machine operational.


As you can see, it is not that difficult to assemble and build your own CNC machine. And, by following the tips and steps from the article above, you’ll be able to make the process of building a CNC machine easier, less time-consuming, as well as less expensive. So, now that you know what you should do, do not waste any more time. Instead, start answering the aforementioned questions and start building a machine that will allow you to do wonders.
