The DIYLILCNC: Open-Source Plans For a Low-Cost, Easy-to-Build CNC Mill. (v1.0.2)

The DIYLILCNC: Open-Source Plans For a Low-Cost, Easy-to-Build CNC Mill. (v1.0.2)
The DIYLILCNC project is a set of plans for an inexpensive, fully functional 3-axis CNC mill that can be built by an individual with basic shop skills and tool access.

CNC devices are used to fabricate physical objects with a high degree of precision. Some CNC devices, including the DIYLILCNC, feature a gantry-mounted cutting tool (like a router) that can move in two or more directions. The operation of the tool is controlled by a computer, which is tasked with translating a digital design into actual tool movement.

The DIYLILCNC can be built for around $700. This cost includes all the stock hardware and sheet material used in construction. CAD files for custom laser-cut parts are distributed along with the plans. Anyone with access to a laser cutter can use these files to fabricate all the panel parts necessary for construction; those without ready laser-cutter access can use local or online laser-cutting services.  Some users have even adapted the files to be cut using another CNC mill.

Plans and instructions for building the DIYLILCNC are distributed freely and intended for wide distribution and modification with few restrictions. The plans are formatted to facilitate easy fabrication, especially for beginners. The DIYLILCNC can be built by an individual, a student group, or a class. Besides being immensely fun, building the DIYLILCNC is a great way to learn about motion control and CAD/CAM/CAE.

Specs
-Cutting bed size: ~12” x 14” x 2”
-Spindle speed: 0-35,000 RPM
-Total cost for hardware, sheet material, motors and driver board: ~$700
-Tested cut materials: foam, hardwood, acrylic, MDF, thin copper sheet

This project is a fusion of two instruction sets published by Stuart McFarlane/Oomlout: CNC1/desktop CNC router (2007) provided the basic design for a functioning CNC mill; How to Make Anything (Using Acrylic and Machine Screws) (2009) details a solution for constructing 90° joints in laser-cuts stock using simple hardware.

The plans and source files presented below were adapted and expanded by: Chris Reilly (www.rainbowlazer.com, www.chris-reilly.org) and Taylor Hokanson (www.taylorhokanson.com) with generous support in the form of funding and facilities from the School of the Art Institute of Chicago (SAIC).

How big are your stepper motors and where did you get them?

nice

So... you use a CNC machine... to make more CNC machines? quite diabolical.

Very nice. I hope to make one soon, once i get a job.

Im a Junior in highschool and we are building this exact model from the guys at DIYLILCNC and so far everything is running great. Its a very well rounded group project that needs a verity of skills.

Great Instructable!!! Im making a CNC machine of my own but I have a few questions. Has anyone used the HobbyCNC EZ Driver Board Kit or the PRO series? Im not sure how to adjust the boards output voltage to match my steppers

Project looks good. i know some folks who built a very similar model. It looked great, thanks for the post!

Does it work with USB?

Search "USB real time", read, then decide for yourself. For me the answer is no.

It looks like the following page also provides a method for making your own CNC mill:

Has anyone tried building it?

Does the software contain the calibration to tell the step settings, how do you configure software to the motor.

Is this CNC meant only for wood or can it be used on harder materials as steel etc?
Looks like a nice piece of machinery.
Jul 2, 2011. 3:23 PM88nightrider says:
Maby a better question.
What is it that limits how hard of a material this CNC can work with?
Jul 2, 2011. 12:02 PM88nightrider says:
If applying this design to metal parts instead of MDF would it not be more rigid?
And converting all the movement to threaded shafts.
Then using bigger motors, and maby something other then my dremel, then It might machine harder materials?
Just looking at designs that would work for me.
Jul 3, 2011. 7:39 AM88nightrider says:
Thank you for your answer.
Well then im thinking about (like I have read in the comments) using Acrylic instead if the MDF.
The Acrylic should have no trouble with the use of coolant/lubrication right? Or heat?
So structurally there should be no problem to mill steel?
I am realy liking the idea of being able to make things in steel or aluminium myself, making parts for for my RC car etc.
Casting of parts would also be cool to do, but I dont see myself doing that with smaller parts.
No problems involved with making changes to the design? Like height and size of the table?
Jan 20, 2011. 9:58 AMmgauvin8810 says:
ok I received 3 quotes for having all the parts laser cut for me. On 1/2" MDF or Acrylic they were all over 3K$. Who would cut these for blue collar pricing???
May 12, 2011. 6:53 AMarthurwhitt says:
I will be glad to quote you blue collar pricing for all your laser parts. Please send me drawings of what you want lasered and I will give you a quote. If there is an interest here I will be glad to provide a complete kit of required lasered parts at one Price. If anyone is interested, I need a set of plans to bid on. If you would be interested in the kit please also send me a email so that I can determine if there is enough interest to go ahead with the kit project. Please send to arthurwhitt@gmail.com. My mailing address is Laser Etch 531 North 150 W, Kaysville, Utah 84037. My telephone number is 801-682-8711.

from your website "Sorry, panel kits are currently out of stock! "
Jan 20, 2011. 11:10 AMmgauvin8810 says:
Thanks, I realized the size mistake, I guess I overlooked that in the excitement of the project. Would Acrylic work for this as well? Also, I would pay $250.00 all day long for these parts! Have a great day! (^^,)

700 dollars? what? Seems like a lot....
Feb 9, 2011. 10:00 PMjohnfanok says:
Assuming I build a machine to accommodate a 4' x 8' piece, will the software allow for any size material parameters? Also, how do you keep the material in place while it's cutting? thanks!
Jan 11, 2011. 12:50 PMtgsnyder says:
I'd really love to see the plans in a format readable by free software (maybe svg for inkscape). I haven't been able to get the files open with any of the software I can get my hands on, to see if the TechShop RDU laser cutter bed is large enough. I don't think it is.

Other than my file format problems, the instructions and parts list in this project are great!
Jan 11, 2011. 8:01 PMtgsnyder says:
I have tried the AI files in the sandbox section, but the version of AI I had access to was too old, and both inkscape and Corel both didn't want to import them. I tried a lot of different (free) software to open the dxf, and only had luck with one (which helpfully merged all the layers for me).

Unfortunately, the laser cutter at TechShop RDU is 18" x 24" so this version is out. I'll definitely keep an eye on the site though.

Thanks for the great documentation on this project!

tgsnyder,
While both of those programs should be able to read the plans just fine, how about trying an intermediary program. There are actually many versions of the DXF format (and then some are binary and some are ASCII), so you might need something that can play well with the distributed files and your software. DraftSight is totally free and works really well. It's from the makers of Solidworks. It's out for both Mac and PC. Here's a link:
http://www.3ds.com/products/draftsight/download-draftsight/?xtor=SEC-6-GOO-[]-[]-S-[draftsight]

Open the files in DraftSight and then "save as..." them, making sure to use R2000-2002 Binary Drawing .DXF. (I know the years are right, the only thing you might need to change is to ASCII)

After that, the file should open in either piece of software just fine. Hope that helps!

has anyone put this on Ponoko ?
Jan 14, 2011. 10:16 AMGlobalVillageIdiot says:
>>Anyone with access to a laser cutter can use these files to fabricate all the panel parts necessary for construction . . .

Could you use the DIYLILCNC to cut the panel parts for a second (third, etc.) DIYLILCNC instead of a laser cutter?

I built one from scratch that could handle a 4 X 8 sheet of plywood for around 1500.00 for making signs. It was mostly wood and used roller blade wheels.
This one is nice, I like it!
