How much time does it take to build a custom CNC machine from scratch?
Building a custom CNC machine from scratch is a difficult task. The difficulty stems from the fact that the machine needs to be accurate, robust, and capable of performing even the most difficult cutting tasks. More importantly, the pulley system that facilitates movement along the x, y and z axes should not affect the accuracy of the cut in any way. It should also be sturdy enough to support the weight of the router and facilitate movement along the z-axis. Therefore, taking all these factors into account requires planning and careful design. This means that the build phase actually begins when you set out to design the CNC machine and ends when you finally put the parts together. Therefore, building a custom CNC machine from scratch can take anywhere from a few weeks to a few months.

How much time does it take to assemble an off-the-shelf CNC machine?
If you don't have the ability to build a custom CNC machine, don't rush. You can buy an off-the-shelf CNC kit/machine and build (assemble) it. These CNC kits/machines are shipped by the manufacturer in a disassembled condition with various parts already cut or machined. Therefore, as a buyer, you do not need to use milling or cutting equipment. Instead, all you need to do is follow the instructions in the package, which should guide you on how to do everything.

How much money do you want to spend on a CNC machine?
Your answer will come in part from whether you intend to use the machine for professional or personal use. However, in both cases, it is always worth trying to get the most bang for your buck. Therefore, you should evaluate which parts and components are necessary for the machine you want to build. If you don't need them, don't buy them! Set a budget for yourself that you know you can afford and stick to it. (We discuss costs in more detail below).

What skills should you have to build a CNC machine?
Building your own CNC machine will be easier if you already have some of the necessary skills. Therefore, the goal is to complete a project that makes use of your experience.

If you already have experience in woodworking or metalworking, then you may want to try a more challenging project. At the same time, a newcomer may want to start with a simpler project. In fact, CNC Cookbook suggests that if this is your first build, you can start with a simpler machine. That way, you're more likely to finish it rather than gritting your teeth and giving up.
