Welcome to RawCNC


Raw is a DIY CNC machine that anyone can build with parts from us or others. There is many similar machines and they are all good, but if you want to use your machine professionally you need to make it stronger and that’s the whole purpose with the Raw project. For our Swedish visitors you can visit www.cncmaskiner.org if you like.

So how do i build this awesome machine?
It’s easy, just purchase the partlist and the drawings. Go to the page “Start here” that you will find on top of this page. When you have the plates or the kit you can start building the machine. The build is well documented with pictures and YouTube videos.

If you are new to all this
We will publish articles that will help you to understand DIY CNC machines. It might look complicated but with some help it’s relatively simple, but you will need some activity in your brain to pull it off, but not much…

So start of buy reading some articles and you are half way in. you will find the articles in the menu above or below
