Picture of Building a CNC router
This instructable will show you how I built my CNC router. I hope you can draw some inspiration from my build and that this instructable will be helpful for your future projects. This instructable shows all the steps I went through in designing and building this CNC router.

The main thing I like about a CNC router, is that it is so versatile. You can use it as a drilling machine, a router, a saw, a mill and even as a lathe. Because my workshop is very small (it’s more like a shed), I didn’t have the  room for all of these tools, but I still wanted to be able to make very precise parts for different projects. That’s why I started to think about building a CNC router.

After doing some research I decided to design and build my own machine. It took me almost 6 months to build and design the machine from start to finish. Before starting the actual designing of the machine, I did a lot of research on the web. I recommend taking a look at the following websites: and These websites will provide you with a ton of information and answer most of your questions on CNC related topics.

Please note:
I built this CNC router as final project for school (also called 'profielwerkstuk' in the Netherlands). When I started the build, I was 16 years old and I finished it when I was 17. Although I have done a couple of larger projects in the past and have been doing FTC robotics for the last few years, I didn’t have that much experience with building CNC machines. This machine actually is the second CNC machine I built.  The first one was a wooden test machine, which I built to gain some experience and learn more about CNC machines. I tried to build this machine as good as possible, with the tools, the knowledge and the budget I had at the time. I think the machine came out pretty nice and I hope you enjoy reading about it.

What kind of materials can it cut?

Benne (author)  buckslayer243 days ago
It can cut all materials softer or as hard as aluminum. Aluminum works well, but I'm currently building a new machine that's a lot more high end and ridgid that will work even better for this. I haven't tried steel, but I don't think it's ridgid enough for that.

like your cnc i want to build one can you send me your drawings and about how much does it cost my email plzzzzzzzzzzzzzzzzzz

Benne (author)  kingkhalid2 months ago
Both the total cost and the drawings that I have are in the Instructable

Hi! Nice Job! Any chance to see a video of it in action? And can you do 3D parts by using the appropriate software to e.g. sculpt wood moving all 3 axis simultaniously? Is this a hardware or software limitation if one can move all 3 axis at once? I have noticed that a lot of people use two motors on the x axis. Have you noticed any need for that? Have you ever thought about driving the nut on the z axis and not a threaded spindle? Would there be any advantage of not moving the z axis stepper motor along with the z-axis? Yes and like one other commenter already stated you did an very good job writing English. Easy to read and understand!

wow you amazing i love to build this router please can you send me the plane and the sketchup drawings

Benne (author)  hasannebso5 months ago

I just added the Sketchup drawings to step 1 of the Instructable. The drawings are not very detailed and not fully complete but I hope they will be helpful. I dont have a full set of plans, but the sketchup drawing and the pictures + documentation should be enough to build your own machine.

hi first of all thanks for sharing this info... great project i want to build this same design but in 2x scale is the same electronics will work and motors torque should be enough for acrylic or aluminium ??? and if possible please send me the plan on i should be really thanks-full to you thanks

How much did this cost overall?

Is there any substitute for the Leadshine M542 co troller because it is'nt available in India.

hey dude, i am salam siddique from mumbai

i have build a cnc mill myself and below are the pics you can see

i have to tell you that it is very tough to find cnc electronics here in india

i myself ordered tb6560 3-axis cnc driver from ebay

so it is good if you order from ebay or you can make one, there are lots of articles on the internet but if you are a beginner i recommend you to buy one

if you need anything just google it........

best of luck....

Gruwelijk vet van je dat je het op Instructables hebt gezet. Dit is echt vet.

lcsmbs11 months ago

I am also designing and building a CNC router but I am not to sure about the dimensions. I want it to be pretty similar to your as I think it is one of the best designs around. Could you please email me the sketchup plan. Email is:

Much appreciated.

Hi and from me very nice project and really understantable posting. I am thinking of making a cnc on my own and i want some help in selecting dimensions of linear rails,bearings etc. and cutting bed?how i will configure the area of cutting?


Benne (author)  todos11 months ago

What materials you should use depends on the size of the machine you want to make, your budget, the precision etc. You'll have to provide a bit more information, so that I can help you better. I used 16mm fully supported rails for the Y and Z axis. You definitely want supported rails, when your machine is larger than 500/500mm. The cutting area will be about 20cm smaller in each axis than the lenght of your rails, but this also depends on your design. A good website with more information is: There you'll find most answers to your questions. Good luck with building your CNC router!

todos Benne11 months ago

Generally i want to cut aluminium and wood as you did and for the frame i will use also aluminium.So your length of the rails in your project is x:1050mm,y:840,z:400 and the travel area almost 20cm smaller in every axis.

It is worth to make a bigger cnc?If i want a cutting area of 1100mmx925mm i will use 1300mm x 1150mm rails?

If i made a bigger from yours i will lose precision and where i should pay attention?It change anything in the z axis;

If it easy for you can you send me some sketch up or any other information for my first steps.I sent my email to you with pm.

Sorry if i am asking stupid things but i am trying to understand what is the best dimensioning for my project.

Thanks and keep going with nice projects!

Benne (author)  todos11 months ago

I just send you an email with the sketchup drawings and some more information that might help you. Hope this helps.

Benne Congratulations on an impressive piece of designing and construction. Is there any chance that you could edit the instructable to include some critical dimensions and a bill of materials and parts (BOMP). Bog Trotter

Benne (author)  Bog Trotter11 months ago

I haven't made a BOM, because most of the materials I ordered locally or from Dutch suppliers. In the instructable you can find the main components I used and the dimensions of the cutting area, rail lenght etc. I can send you the sketchup drawings, if you pm me your email address, but the drawings arent very detailed. If you want to make a copy/similar CNC router, I'm afraid that you will have to figure out a lot of dimensions yourself and see what materials you can use. But the sketchup drawings and all of the pictures probably can help.

I can not tell you how much I admire the work you did here, and the quality of the instructable you have made. You will do well in whatever you undertake. I'd like to add that your English is fantastic.

Benne (author)  benwade11 months ago

Thank you very much for your comment, I really appreciate it!!!

Benne (author)  Nazir Naseer11 months ago

Nice, so you even made your own electronics, very cool!

mbrock1311 months ago

First off great build! Your work has inspired me to build one as well. I had one question for you though. I am wondering what the dimensions of the side plates of the gantry were? thank you in advance for your help!

Benne (author)  mbrock1311 months ago

Thanks! The side plates are: 200x530x15mm. I can send you the sketchup drawings, but I'll need your email address. The sketchup drawings are not extremely detailed nor fully complete, but they probably will be helpful if you want to build your own.

nice, how much did jtcost you to make
