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 you can buy the parts from www.cncmaskiner.org , motedis.com or others. You will how ever need the plates. You can purchase them pre-cut or make them your self with our stencils. Go to www.cncmaskiner.org to find out more.  When you have the plates you can start building the machine. The build is well documented with pictures and YouTube videos.

Help us to improve Raw1.3!
We want you to contribute, we need Raw1.3 machines with laser, 3D printing and plasma add-ons. By switching the Z-axis all this will be possible. We will have a section where you can present your ideas. Let us know if you want to participate.

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

4 motors on a 3-axle machine?

4 motors on a 3-axle machine? As you may have seen most that build a 3-axis machine (up-down, left-right, front-rear) have 4 lead screws or belts and 4 motors. One motor for the Z-axis (up-down) one for the X-axis (left-right) and two for the Y-axis (front-back). XYZ axes can be confusing. When we talk CNC machine Read more

Home or limit switches

Home or limit switches A switch is a small on/off button that sits at 5-6 spots on your machine. One on each side of an axis. The z-axis (up down) has only one on top. These switches are the machine’s way to understand where it is located or if it traveled outside their area of Read more
