LOW COST DIY 500€ CNC MILL

by Vulcaman

Hi,

in this Instructable I want to show you, how you can build your own CNC-Mill for less then 500€less then 500€. I designed this machinefor CNC-beginners, who don't want to spend a lot of money for their rst experiences with CNC machines but alsoexpecting a rigidrigid and professionalprofessional looking CNC.

This machine is perfect for maker, tinkerer and everyone who wants to start CNC-Machining.

In the pricerange of sub 500€ you will not nd any other CNC with these features:

710 Watt spindle710 Watt spindle motorMGN linear-rails on all axis linear-rails on all axis1204 ballscrews on all axisballscrews on all axise ective workarea of 250x220mm250x220mmmax. travelspeed of 3000mm/min (at 12V)3000mm/min (at 12V)high accuracyaccuracy of 0.1mm0.1mm in all axissuper rigidrigidportal frameportal frame (out of one piece of wood and aluminium extrusions)

Below on this site, you will nd a detailed instruction + a bill of materials (BOM) with links, where you can source therequired parts.

The complete CNC is build out of CNC milled screen printing wood plates. So assembling will not be a problem. For thebuild you don't need any expensive tools like (3D-Printers, CNC or Lasers). The only special tool is a M5 and M6 threadcutter.

LOW COST DIY 500€ CNC MILL: Page 28

Step 21: Software

For the electronics I am using an Arduino Uno with aCNC-shield. This is the cheapest methode to controll theCNC.

For the connection you have to connect the X-Motor tothe X-Motor-Port, the Y-Motor to the Y-Motor-Port andthe Z-Motor to the Z-Motor Port. Then you have toconnect 12V to the board at the blue terminal pins. Afterthat connect it to your PC and ash the software (GRBLor ESTLCAM) to the Arduino.

Now you should be able to move your machine.

(coming soon):

On the machine there are also holders for inductive12mm end switches in the CNC milled frame. I am stillwaiting for delivery, so when they arrieved, I will updatethe instruction.

LOW COST DIY 500€ CNC MILL: Page 29

Step 22: Configure Estlcam for This Machine

To controll the machine you need 3 types of software:

1. CAD software:1. CAD software:

Inside the CAD software you create your 3D-File, whichyou want to manufature. I personally use Fusion360 forthis kind of application.

22.CAM software:.CAM software:

In the CAM software you de ne the tool path of yourCNC machine, here you can also use Fusion360, becauseit has a build in CAM-module.

3. G-code Sender: 3. G-code Sender:

The G-code sender took the G-code le, from the CAM-Software and sends it to the controller of the machine.Because I am using an Arduino as the controller you canuse GRBL as a software on the Arduino and a G-codesender like "Univerversal-Gcode-Sender" or "bcnc"

As an alternative I also want to mention Estlcam. InEstlcam, the CAM and controller part are combined inone software (If you use an Arduino as your controller).Also it is more simple to use compared to other CAMSoftware.

I personally recommend to use Estlcam over GRBL for this CNC because of these aspects:

It is a lot easier to con gurate than GRBLIt has a build in CAM, so you don't need any additional Software

LOW COST DIY 500€ CNC MILL: Page 30

Controller and CAM are combined in one Software

Now I want to show you which con guration you have to do, that the machine will work propably:

1. Open Estlcam and go to "Einstellungen" then click on "CNC Steuerung"

2. After

that a window will open with some con gurations. There you will see all the basic values for this machine. Once you haveall the settings like in the picture, connect your Arduino to your computer, select the right COM-Port, click on"Steuerung-Programmieren":

LOW COST DIY 500€ CNC MILL: Page 31

3. If the programming of the Arduino was a success, close "Estlcam" and open "CNC-Controller". Now you should be ableto move your machine.

Can anyone point me to the .dxf files for the machined parts?

This looks awesome, thanks. Unfortunately not having the cutout files would be a real pain.Someone has to do the work finding all the measurements and from there extrapolate theshapes. You don't even ship the cutouts to Canada. The community needs a truly open-sourcemachine.

Great machine. Love mine. I got great help from Haraldhartmann78. First prosjekt I made aenclosure for the electronics. Second a dustshoe

I built the machine including small changes. control with estlcam incl. limit switches.

Mee to can't seem to find the files for the CNC parts. I am thinking about having them jetted outof alu. Are those files still available?

Hi,

How can I download your parts. I want to do it by different materials, but I dont see and can'tdownload some of your part. If you can, will you share your design with my Fusion 360 account1511026@hcmut.edu.vn.

Thanks so much and best wish for you!

The parts list unfortunately lacks the 2 250 mm aluminum profiles required in step 12.

I already informed him in july via email.Step 17 lacks some m4 6mm t-slot-nuts and some shorter m4x12, because you have to mounttwo angle brackets in the portal aluminium profile

I am stuck in my build in this stepp. I ordered the last profile on aliexpress. My steppers waswithout conections, so I orderd a crimp pilers to.

I made it! It works like a charm. I milled some slade plate, too.From the remainder of the cutouts I have milled some clamps and tensioners.Since I photographed every step, I made a stopmotion out of it, have a look.

In the introduction you mentioned "The only special tool is a M5 and M6 thread cutter."The M5 thread cutter isn't mentioned further. I think you have to use it in Step 6 "The PortalSide", right?

Hi,

you only need the thread cutter for the aluminium extrusions, to create the front threads.

Danke für das Gespräch auf der Maker Faire!Viel Glück beim Wettbewerb. Habt meine Stimme.

Freut mich zu höhren, dass es ihnen gefallen hat. Vielleicht sieht man sich irgendwo ja nochmal :-)

Excellent guide, really well made and useful.I have only one question: how did you align axis? How do you guarantee the perfect coplanarityof the X-Y axis and the perpendicularity between the 3 axes? Are there any adjustments?Thank you

Me again. Just voted for you in the Make a Tool competition. Good luck with that.You've probably already thought about crowdfunding: if you were thinking of offering a completekit of parts you'd obviously have some upfront costs in obtaining everything and holding stock. Acrowdfunder would be a great way to get the money to be able to start offering full kits. I am sureit would be popular.

Very nice instructables, one of the very best i have ever seen! Every part explained very well, ican't wait to start building mine! :)

Thanks for your feedback! I can't wait to see your version of the CNC :-)

Are you going to publish your Arduino sketch file ? Please.Don't want to buy frame parts without the ".ino" file.Thanks

Thanks for your feedback. I will publish the config files for the Arduino tomorrow. However, pleasetake a look at Estlcam, it is super easy to configure. In Estlcam you only need to set yourdimensions, steps per mm and max. feedrates. Then Estlcam will flash the Arduino automaticly.And you are done with the configuration.

Thanks for your quick reply, look forward to seeing more, always wanted to make a cnc mill. I amat the other end to you .I'm 75 and still building.

LOW COST DIY 500€ CNC MILL: Page 34

I have added a step, where you can see, how the software needs to be configurated. I have alsoadded a video of a test run. Please take a look at step 22.

Thanks for such a detailed instructable, it is very inspiring. I'm currently learning fusion360 forCAD/CAM and gcode.I can't find the files for the CNC milled parts or the fusion file. Will you publish also that file? Will help me a lot to learn from an experienced user! All best /l

Thanks for your feedback. I don't want to publish the Fusion file. But you can use the 3D-Onlineviewer. There is a measurement function, so you can take all the dimensions manually. So withknowing the dimensions it should be possible to reconstruct the CNC. This is also a good trainingto learn fusion 360.

Ok thanks for the fast answer. I thought to get those files or the single parts, there was something related to the online viewer oron the fusion software that I was not catching.Good luck with the project.

There is only 1 type of plywood that is made well enough to not have voids, and be stiff enoughto be successfully used in a CNC machine. That being Baltic Birch and those parts are not BalticBirch. The metric equivalent to 1/2" Baltic Birch has 9 plies all birch. The metric equivalent to 3/4"has 11 plies all birch. It is sold in 1500mm x 1500mm sheets (5' x 5") That machine is likely goodenough for wood projects, but not metal.

Very well-done and well-documented. Nice work!

Can that machine mill aluminum ?

Yes it is possible to mill aluminium on that machine, but do not expect the best results. I think foraluminium sheets with up to 3mm it will work good, but you will not be able to produce aluminiumparts like in my other instructable: https://www.instructables.com/id/DIY-IRONLESS-LINE...If you want to mill aluminium the right way, you need a more rigid frame (out of aluminium) and aspindle, where you can controll the speed. I think if you will build this machine completely out ofaluminium and use a spindle with a speed controll, you would be able to produce parts like in myother instructable.

Congratulations ! I thing you engineered a pretty capable CNC router. I see nothing wrong aboutit. Straighteners for the Xends, a pretty stiff spindle carriage, good rails and correct transmission.Well done !

Thanks for your feedback :-)

WOW, Great instructable... Detail explain on steps.. Did lots of work..

Thanks for your feedback :-)

Can you advise (approx) postage/freight costs for the CNC-Milled parts to Brisbane, Australia.

The shipping costs to australia will be 62€.

Good job, thank you for sharing. Just checking if Nema 17 is good for it or maybe Nema 23 would be a better choise.

For this CNC, a Nema 17 is a good choice, a Nema 23 is kind of over powered for thisapplication. Because of the ballscrew , you will get enough force to cut though material withoutloosing any steps.

LOW COST DIY 500€ CNC MILL: Page 35

Thank for this ...The link to your site is no longer valid !!!Super project, not having a CNC (a bit for that I look at your sharing) I would be interested in thisone. Could you give this one?Merci ;)

Thanks for your feedback. That is curious, I have checked all the links and they work correctly.What link do you mean exactly? Do you mean my website? Here is the link for it:https://www.vulcaman.de/

Nicely done. One of the few instructable on CNC's posted that included limit switches in thedesign.

I just wanted to throw this out there, if you're going to build this do not put this in an unheatedshop, damp basement, or unheated garage.CNC's are precision machines. Because it includes wood material, it will shrink or swelldepending on the weather. And. That will destroy any sort of tolerances.

Considering using plastics or metal instead of wood for the frame

Well done! Thank you for sharing your files and plans :D
