Buying Guide for DIY CNC Routers

A user should know some important things before purchasing and using a CNC router at their place. So, we have gathered some important points that would help you in making this decision of yours.

Apart from the general factors that you should consider before making your purchase, we will also discuss some features found in DIY CNC routers and what it would mean if you had them.

Programming and software

As you know that every CNC router is programmed and operated differently than others. If the model is entirely a new entry to the market, don’t buy the product unless you’re sure about the software used and the codes you would have to insert.

We’ve seen that different versions of the software can be used to operate the machine. It will certainly be a plus point if you’ve already used a CNC machine earlier, as you would be somewhat familiar with the G-code and operating procedures that go with it.

For operating the spindle motor (milling) and laser module, multiple open-source applications produce excellent results. The Laser Module Software v3.0.14 and the GRBL 1.1 are widely used for operating desktop CNC routers.

It is easier to work on vector images, but you may face difficulties learning how to operate them. For this, you can always refer to user manuals and even watch a YouTube video online to get yourself acquainted with it.

Spindle motor

This is the high-precision motor that is located normally on the Z-axis of the machine. They rotate on that axis and are controlled by the software on the system or the offline controller. You should know the amperage draw, the size, the type of spindle, the rating, and the RPM that the spindle has. A standard CNC router would feature a 775 spindle with a max rotation speed of 10000 RPM.

Brands

There is definitely immense competition in the market when it comes to desktop CNC routers. With so many brands, it becomes tough to choose one even after comparing their features. For those that want to use an imported machine, always check the availability of customer support services beforehand.

Price

When you’re stuck between choosing one of the shortlisted CNC routers that contain similar features, the deciding factor should be the price. This includes considering the price of something extra offered by one of those choices, e.g., an enclosure. Compare the effective price of the router and the availability of the parts used to assemble it.

Spare Parts

Some spare parts are included in deals mentioned on Amazon and other online sites. You can look at the individual prices of those components in case they get damaged or overused.

This is a critical aspect of using some of the high-end industrial-grade CNC machines, but for these desktop CNC routers, you can easily find these parts in a nearby hardware store. These parts are usually affordable, and if they’re unavailable locally, you can always purchase them on Amazon.

User manuals & instructions

Going through the user manuals that come with the CNC router kit helps assemble and operate the machine, especially if it’s user-friendly. It lists all technical specifications that would assist you in buying replacement parts later on.

Sadly, as we’ve read throughout the product reviews, the majority of the routers come with confusing instructions, which waste a lot of time for the users. Many customers have instead referred to online videos for assembling the machine and operating the software.

Enclosure

Some models also feature an enclosure around the aluminum frame, made from acrylic sheets and fixed on all sides. This enclosure provides protection against any scattering and flying pieces of wood and other materials. You can see perfectly well what’s happening inside while saving yourself from any work-related injuries.

Laser engraving

Some routers also feature a laser module for engraving. This laser module ranges from 3W to 7W power output in desktop CNC routers, featuring an emitting aperture. You can manually adjust the focal length of the laser by rotating the knob that is positioned at the module’s head.

To provide improved performance, they are made from durable aluminum with a heat sink groove. This ensures that the temperature level doesn’t rise too much and heat is dissipated frequently from the module for safety.

Weight and dimensions

Always look at the weight of the CNC router and the dimensions of the frame. This would help you position your machine better on your desktop. Having a heavier CNC machine is generally considered a sign that quality parts are used to make it, but this isn’t always the case. Sometimes, heavy parts make it difficult for the frame to remain stable, making it difficult to move it to another place if your work demands you to do so.

Type of materials

With these CNC routers, you cannot engrave nor cut hard metals like steel, as the engraving tool nor the motor is powerful enough to do this.

Despite this, you can use it on many materials like acrylics, plastics, carbon fiber, PVC, PCB, wood, epoxy resin boards, sponges, and even engraving on aluminum, copper, and silver.

This would obviously depend on the brand of router you’re buying, so you’ll have to see whether your choice of router is capable of engraving and cutting through these materials. You can do some amazing DIY projects and also construct signboards and 3D designs from them.

Supported OS

Before buying, check whether the software used to operate the CNC would be compatible with the type & version of OS you’re running on your system. As we’ve seen, the majority of the routers are compatible with Windows, while it becomes difficult finding those that can work on Linux and MacOS.

You can also ask the manufacturer if you’re unsure about the supported operating system, as sometimes product descriptions are not that accurate.

Offline controller

Modern CNC machines are equipped with an offline controller that is powered by a control board. This removes the need to stay connected to the PC while engraving. You can simply load the vector images on a memory card and then plug them into the controller to make them work. You don’t have to worry about the storage capacity as they support up to 1GB of data.

Having a controller works best when your router doesn’t work on your system’s OS. Some brands also feature more aesthetic controllers with an LCD screen to enhance the user experience.

Final Verdict

These routers are designed to complete small projects and tend to be an excellent way for beginners to start wood engraving work. They are way cheaper than industrial machines, but they can deliver reasonable performance for DIY tasks.

These machines are priced low because they do not come pre-assembled. The parts come separately, and you have to spend some hours trying to put them together. With the help of a guide online, you can do this easily as well.

Overall, the routers mentioned in our list are highly recommended and frequently bought by customers in the market.
