The popularity of the CNC router is rapidly increasing, from hobbyist to large and small businesses alike. People are always finding new ways to utilize these amazing machines.

Looking to Buy?
Maybe you have already decided to make the investment and purchase a CNC router for personal or business use, but would like to know how to select the right broduct for your needs. Many questions arise when shopping for a CNC router.

What size do I need? What features should I get? How much should I expect to pay

There are literally hundreds of models and features available. Each machine is designed to operate in certain conditions and perform certain tasks.

So you may be asking yourself, “Where do I start?”

This is where our Buyer's Guide will help you. It will coach you through every step of buying a CNC router. It will cover everything from identifying the right router for your application to discussing pricing and optional features.

Looking to Build Your Own?

Building a CNC router can be a rewarding experience. It can save you a lot of money and allows you the option of designing and building a machine to fit your need specifically. Not to mention its a lot of fun is a very rewarding and a great learning experience.

At this point you may have some idea of your design and how you want to build it. Or maybe you have no idea and are still gathering parts. Either way, you have come to the right place.

No matter what stage of your project you are in, take a look at our Builder's Guide. NO it is not one of those blue prints you can buy that shows you how to build that specific design. In the Builder’s Guide you’ll find things like:

A complete a breakdown of all the parts you’ll need and their function.
Frame design and materials selection
Money saving Tips
and more!

It will look at every part of these machines down to the wire, literally. The guide outlines the do’s and don’t and explains some common design flaws in many homemade versions.

Need General Information?

So maybe you don’t want to buy or build a CNC machine. You may just be looking for some general information on these machines. Well, you’re still at the right place. Here you will find everything from the breakdown of all the types of CNC machines down to their individual parts and how they work, to the software and electronics needed to make them operate.

Routers are amazing machines and we want to offer as much information about these machines as possible. So thank you for visiting our site and please bear with us as we update and populate this website daily.

If you do not find the information you were looking for, please do not hesitate to contact us with any questions or comments. We will respond as soon as possible.
