This is my second DIY 3 axis cnc machine. It is designed in solidworks 2008 (~50-60 hours) and built mostly out of MDF. Provided are all the source files and drawings in both Solidworks and edrawing formats. This machine is possible to make with just some hand & power tools, but I used my first cnc machine to make most of the smaller parts.

The machine uses chinese linear rails and ballscrews from ebay seller linearmotionbearings2008. With the 1.8Nm stepper motors I use with geckodrive g540 it achieves up to 5m/min rapids and 3m/min feedrates. The working area is about 110cm x 60cm x 10cm.

Expected cost to build a machine like this from scratch is 1000-1300 euros. It also took me over 80 hours to construct.

I have been running different machine tools for 40 + years. I believe you can cut just about anything. It depends on how sturdy your setup is and how sharp tool is.How deep cut, So if you try something and it does not feel right, Too much chatter, you may want to try less depth of cut. I have a CNC machine and I want to change CNC guts in it. Also just traded for another CNC machine. It is supposed to be in working order. Have a Makerbot Replicator 2. So you see I am having lots of fun. If at first you do not succede, Study situation and figure out how you can do it differently and keep on trying. The harder you work, the more likely you will to increase your luck.

oeps I used the wrong name i see ;-( my post is two the owner METALFUSION

Hi Jfrancis first off very nice build!!!! I have a newby question ;). I downloaded the files but i could not find the BOM list. could you tell me the name if its in de total filelist or provide me the BOM list? This would help me with knowing what 2 buy. also did you made a step by step guide on how two get all parts together? This will be my first try in the asome world of cnc ;-) and maybe this build will help me get it done for it is a nice build. Almost forgot.... Could i use this machine for cutting aluminium? not that this will be done anywhere soon because i will be doing wood builds for a while ;-)

This is a fantastic machine! Thanks for sharing!

Hi, the zip file of solidworks parts here is corrupt. can you revise it?

You are right, there seems to be a character encoding problem with some of the part files.
I have packaged the latest version of the model with SolidWorks 2011 and added it as a separate download. I don't have the older files or SW 2008 installed anymore but hopefully this helps.

Awesome, Thanks so much!

hi, i am new to cnc machines and i find the "plans" confusing and I cant understand the lists in the pdf. would you be able to help?


Well, I originally made the 3d model and 2d drawings with only my own use in mind. All the parts are named in Finnish. The names aren't that informative even if you understand Finnish, though. :-P

There are dimensioned drawings of all "hand-made" sub-assemblies, and those have the different parts numbered with balloons pointing at them. The the BOM ( Bill Of Materials) then tells you the dimensions of the piece and how many of them there are in that sub-assembly.

Downloading the edrawings
3d model and exploring that by hiding parts etc. is probably the best way to get a general idea of how it is built.

hi, I would like to know the brand of Router, is it a 2HP Router? Where can I find it? If possible, please provide the link. Thanks! :)

It is a Co / Tech 2kW model. I would suggest getting a kress 1.5kW or a bosch instead.

I've been following your building process in CNC harrastus forum. Impressive work, I say!

It seems there are many cnc hobby people around Tampere area. We should meet some time and share experience and knowledge... Of course it's nice to get to know new people and meet face-to-face.

I've seen something similar on http://buildyourcnc.combuildyourcnc.com, did you pull from that, or build it from scratch?

Inspiration and design ideas are from multiple sources, but the complete design and build is mine. My first router was strongly based on the buildyourcnc basic design though. It all started from an empty solidworks file and later a pile of rectangular mdf pieces. Nearly all of the router machines with moving gantry look alike. ;)

what software do you use to generate toolpaths for it?

Very nicely build! Would be interesting to see it in person someday - I saw that you

are from Tampere / Finland also :)

My workshop is at the center of Nokia (town). I have also made few DIY cnc-machines and converted one small lathe for cnc. Currently I'm building Mendel Prusa 3D printer with an Cupcake 3D printer.

Would be nice to grab a cup of coffee sometime somewhere and perhaps get to see your great work!

hanks for sharing the plans! My builds are at http://yty.net/cncyty.net/cnc and http://yty.net/cnc/v2yty.net/cnc/v2. You are also welcome to visit my workshop if interested. Just mail me, first dot last at the gmail dot com.
