CNC routers come in all shapes and sizes, from small benchtop machines to large industrial machines – and one of the most popular is 4×4 CNC routers (or “4 foot by 4 foot”).
This larger size is ideal for industry professionals, folks looking to start a CNC business, or serious hobbyists looking to create larger CNC projects.
But how do you find the best 4×4 CNC router for you?
Inventables X-Carve Pro 4×4 is the best choice for most people looking to invest in a 4×4 CNC machine for their small business. It offers unparalleled speed, accuracy, and precision, with easy setup and a wide range of software compatibility.
If you’re on a tighter budget it’s worth checking out BobsCNC KL744 4×4 CNC Router or the Zenbot 4848 4×4 CNC Router Kit. These picks are both capable of precise milling and will cover the vast majority of your home workshop needs.
In this guide, I’ll share my hands-on experiences with some of the best 4×4 CNC machines around.
We’ll take a close look at how the specs and features of each machine compare so that you can make the right choice so that you can easily pick out the right one for you – and avoid the common beginner oversights!

X-Carve Pro is the upgraded version of Inventables’ standard X-Carve, and in our opinion is the best 4×4 CNC router in the $10,000 price range.
It’s designed for speed, accuracy and precision, and despite being 4×4 feet, can cut full 4×8’ sheets, just with the 4-foot limit on width, and 4-inch depth limitations. This is due to the Tiling features in Easel Pro (it comes with a free 3-year subscription), which is specially designed for the X-Carve Pro 4×4 and 2×4 versions for cutting 4×8 sheets.
Easel Pro is an all-in-one CNC software, and if you have other CNC routers in your workshop, it’s also optimized for over 30 other types — but if you prefer, you can still use AutoCAD, Fusion 360, Solidworks, or other CAD CAM software with the X-Carve 2×4.
The Inventables X-Carve 4×4 features a 1.5kW, 2hp air-cooled spindle and pre-programmed VFD, offering 8000 to 24000 RPM and 0.001” accuracy. The 25mm ballscrews and linear guides make for unmatched rigidity and durability — it is quite rightly sold as “industrial-grade CNC at small-business prices.”
You have both the 2×4 or 4×4 CNC option — you’ll pay just under $9,000 for the 2×4, or just over $10,000 for the 4×4, but both with the Tiling Mode features can cut full 4×8 sheets.
Inventables have made efforts to make setup as simple as possible, and you can get started in under 2 hours with the X-Carve 4×4 CNC. The new dust shoe also improves dust and debris collection during work.
When you buy via Matterhackers, the full bundle comes with controller and cables, separate control with pause, resume and reset button controls, a z-probe, e-stop, v-bit with 0.25” shank, a clamp set, dust control system comprising a dust show and hose arm, a planning bit, and a 0.25” high-speed 2-flute uncut bit.
The X-Carve 4×4 CNC router can cut:
- Woods: plywood, hardwoods, softwoods, MDF
- Plastics: HDPE, Polycarbonate, acrylic, Corian, Delrin
- Metals: aluminum, brass, copper

BobsCNC Evo 4 – Best Smaller CNC Router
- Price: $1,130.00 — Available on Amazon here
- Weight: 47lbs
- Material Compatibility: wood, plastics, foam, acrylic, and aluminum
Affordable and powerful.
Stable and durable machine.
Great features are available.
2×2 machine so will take slightly longer to use than a 4×4 CNC machine.
If you’ve read our guide and decided you don’t need all the space of a 4×4 router, or if they’re slightly out of your budget, a 2×2 CNC router is a good alternative that still offers decent working space.
The BobsCNC Evo 4 is our recommended 2×2 CNC router as it’s affordable yet powerful, accurate and durable. You can still create most of the same projects as you can with a 4×4 CNC machine, but it may just take slightly longer using a smaller router.
This CNC is a super stable machine with 0.0002-0.0004” repeatability, thanks to the laser-cut wood frame and SG20U supported rail system. The use of wood in the frame rather than metal also means it’s a lot quiter than many other routers. However, you can still work on a wide range of materials including soft metals like aluminum.
There are some great features that set this apart from other 2×2 routers. For example, it has adjustable eccentric spacers for keeping the bearings tight to the rails, as well as a TR8 Acme Rod on the Z-axis to improve Z-travel speed. The Derlin Acme nut also means you don’t need to lubricate the Z-drive.
This router is also very user-friendly and ideal for hobbyists. It’s really simple to set up, uses the intuitive Arduino software, and there are over 100 videos on the BobsCNC YouTube channel for free training.
The Evolution series of machines, which stand out for their laser-cut wooden frames and somewhat unusual designs, with the Evo 4 being the best in the line, are possibly the most well-known products from BobsCNC.
A Closer Look at 4×4 CNC Routers
When it comes to buying a CNC router, arguably the most important factor to consider is your work area size. After all, you need to have a large enough machine to create your business’ products or hobbyist projects.
A 4ft x 4ft CNC router is fairly large in comparison to many other machines. For example, many hobbyists and beginner CNC enthusiasts choose to go for desktop machines, which are very small and can easily fit in your home or working studio. Desktop CNC machines come in different dimensions, such as 300mm x 180mm — called 3018 CNC machines — or 600mm x 400mm: 6040 machines.
You can pick up these smaller machines for a couple of hundred dollars and they’re the ideal size for small home projects. In contrast, a much larger 4×4 CNC router table will set you back several thousands of dollars.
The larger size of 4×4 CNC routers means they’re widely used by small businesses and in industrial production. For example, the larger size means they’re much better suited to carpenters making things like doors and cabinets, and advertising companies making large signs.
4×4 isn’t the largest size a CNC router can come in. 4×8 CNC routers are also popular, while there are even larger machines used in high intensity industrial production. But with a 4×4 machine, you can create a wide range of projects working with a variety of materials like wood, plastics and metals.
