A CNC router machine is probably the most useful tool a hobbyist can own, but the price for a CNC machine on the market is way more than the average hobbyist is willing to spend. You can build your own CNC with very basic tools, little knowledge of machinery, mechanics, or electronics, but be warned, these machines are inherently dangerous, so wear the proper protection and use common sense. At the very least, read the instructions and precautions on every tool you use.
Now, a CNC stands for Computer Numerical Control, but that is gibberish. It does hint you to the fact that something is controlled, and probably by a computer. It's really a mechanism that interfaces to a computer to control its movements, similar to a robot, but this machine has a specific function. It cuts or shapes things with this control. In essence, a computer precisely controls a cutting tool, like a router for instance, to cut materials such as wood, plastic or metals into shapes only bounded by your imagination.
This five-part video tutorial will show you how to assemble a CNC router kit. With this CNC Router kit, you can easily set it up in no time, just by following along to the instructions here.
The CNC Machine Version 1.2 Kit is quite an advanced kit to put together. Most kits that you find on the market today use plans and paper instructions to assist in the assembly, but these are videos. By showing the assembly through a video process, you will fully understand how to put this machine together. Remember, this is not furniture, it's a machine full of moving parts that require care and attention.
