In this video I will show you how I built the simplest CNC machine with minimum parts possible and without using a 3D printer. That’s right. I’ve been using 3D printers for most of my recent projects because, of course, they are great for prototyping as we can easily make any shape we want with them. However, not everyone has a 3D printer, so therefore I wanted to show you that we can also make stuff even without the help of 3D printers or other CNC machines.

Followed this guide & built my very own engraver today! I was able to convert the drawings into stls & 3d print all. I had to change a few things to get it to fit / work. But overall Happy! I'll make a video

What I loved your part is, you can easily make those drills and cutting in CNC. But did it in handy. you give a hope to everyone who haven't accessable a CNC router. You made a confidence like you can do it.

What a great project to get started with Arduino and CNC.

[PiefacePete]

Thanks Dejan, that one is a "keeper". I already have everything except the rails, and it will be a perfect project to share with my grandson who is just starting to show an interest in these types of project. I think a pen plotter would be a good place to start.

Nice build! Keep in mind you need to have your belts parallel to the axis. Yours are angled slightly which means the belt gets tighter/looser as it gets closer or further away from the end points.

Thanks for this. I have looked at many, many, many CNC machines and this is by far the easiest and least expensive to build. I'm not a fan of the slider blocks used here because they get dirty so easy but since this is a laser CNC and not cutting wood like other CNC's, I think they will work just fine. Great job!

Hello sir,
Why my stepper motor is not continuously and moving in perticular axis while pressing the arrow keys and even movement is not content sometime it moves to Relatively large distance some times very little, sometimes not at all no matter how long I press the moving command keys or at any Step Level and sometimes the software misbehave ( not only this but other cnc software giving same problem), 1st i thought its Smps causing the noise I changed I even rapped stepper wires around choking ferrite but same issue so far it moves somewhat constantly but very tiny amount why?
I am using clone uno with ch3 type installed driver?

Wow, thank you for this. I appreciate the frugal take on this. I'm in design and part purchase phase. But I also want to create a machine with upgrade ability if i want to eventually get a CO2 tube. So I am going with a fairly sizable extrusion frame. But I was debating on a tslot/vslot combo, a tslot/linear rail combo, or tslot/linear rail (x)/linear rod(y&z) combo. But the ingenuity of using wood has me reconsidering because I can get more laser for my buck if I cut costs and use what I have in lumber and just buy rails. I so appreciate you taking the time to do this.

truly the highest quality content, you never fail to deliver. I've been wanting to make something like this myself for a while

[adamderbent]

Izvrsno. Bravo majstore. Imam prijedlog, kako povećat preciznost. Kod kalkulacije step/mm, koristiti maksimalnu raspoloživu dužinu raila. Ako je raspoloživo 400 mm, mjeriti i kalkulitati na cijeloj dužini. Naime, ako je greška očitavanja 1%, na 10mm to je jako puno. Na 400 mm, greška je prihvatljiva.

Awesome video, you are actually one of the reasons I study mechatronics now. Thank you for your content and your exelent way of showing how interesting mechatronics is !

[snapman]

Please list the parts in addition to the links to buy them, as the current amazon links you posted are out of date.

[sufaraba]

Can you tell us more about stepper and driver spec.?

This is a nice project to learn cnc control as this could be upgraded slightly to use a small engraver motor, however, the use of MDF, the dust from MDF contains FORMALDAHIDE which is very toxic, so dust mask and good extraction, ANY wood material will absorb moisture from the air, so, you could either use same thickness large plastic (nylon)chopping board which will not warp with heat or moisture or water down PVA white glue to make an emulsion to paint all surfaces of the MDF after cutting to size, this will make it waterproof, make all screw holes self tap or drill holes and add emulssion, removing excess with a cocktail stick from screw holes.

Nylon chopping boards can be found quite cheap, and are very strong and stiff when used in the proper dimentional axis to force, it can bend but will not compress easy so proper use is a must, along with PVA emulssion treated MDF, a very strong stiff frame can be made, though this project is very nice and the use of good linear rails is very commendable.

Super excited to give this DIY laser engraver a try! Looks like a fun project to tackle 🔥💪🏼

[OGMann]

Don't forget focal point. Should be in the laser specs. As pointed out, the belt positioning is also important. Curious as to resolution with this setup? I see these steppers are 1.8 degrees. Without additional hw, I'm assuming no half or finer stepping.

[danielricardoaugustowood]

Great work, thank you very much for sharing your work and teaching how to do it!

[mubarak]

I made thisss finallllyyy. Thank you so much..it workssss..this is my first doing something awesome. I can't thank you enough for this

[nfaaszcompany]

dear, In my Project One of the motor it's working only one side what can i do for 2 side work?

[KevOXO]

I like the way you show how to build this, no 'this is what I prepared earlier' or pretending every hole was precisely on target.
