This Instructable is not going to be a step by step build log of my machine, but an overview of my design and what I learned over the course of this build. Hopefully I can share a few things to help with your CNC build.

My frame design was based on various moving gantry CNC routers from around the internet, with a few alterations. I chose aluminum as my building material mainly because it was easily cuttable with the tools I had available, and I figured it would have much greater stability than a wood frame.

dbc1218's DIY-CNC-router build (https://www.instructables.com/id/DIY-CNC-Router/) guided me through most of the internals of the system such as the linear guide rails, ACME lead screws and nuts, and also with the CNC controller and stepper motors. If you want a step-by-step guide I would strongly recommend dbc1281's instructable.

Step 1: Frame Build

The frame was built using mostly 1/4in 6061 aluminum from onlinemetals. All of the aluminum cuts were done using a standard miter saw fitted with a carbide blade. Cutting was very precise, and quite fast, even when cutting 1/4x3in plate. A drill press was essential for this project. I learned very quickly that a center punch does not help at all with alignment of holes if you choose to drill by hand.

Do you know the name of the site is instructables it is a place where there is step by step instructions on how to build or make something
<p>That's rude... While step by step is nice there is plenty of information here to make this a good Instructable !! THANK YOU for sharing !!</p>
<p>A picture is worth a thousand words. Thanks for sharing the pictures. Nice build. </p>
<p>It is nice to give lots of instruction, but combined with the references I think your instructable is a good addition to the site. Thanks.</p>
<p>I'm just happy to see someone make a CNC router without gobs of 8020 for a change.</p>
<p>Hi Pfred2, Funny your comment actually introduced me to 80/20... I'd never heard of it. It seems like a great toolkit, so I'm wondering if your comment had more to do with how often people use it, or if you thought it was an inferior (capability-wise, not looks-wise) approach. I don't have a lot of tools around, so it'd appear to be a pretty sweet solution to building metal infrastructure. Is there some flaw I should know about before buying into that scheme, or was your comment more about the aesthetics? Curious. </p><p>Dave </p><p>PS. cdroster, I enjoyed reading about your router build too -- thanks!</p>
<p>8020 is great if money is no object. Well, as great as extruded aluminum can be I suppose. Although be careful, not all 8020 is first run 8020. If you find a bargain you've probably found something else too.</p>
