CNC routers continue to grow in popularity in the woodworking community. As that popularity grows, the number of companies producing outstanding routers grows as well. 2021 is poised to be another huge year in the 4×8 CNC router industry.

Prices should continue to drop as the technology behind these wood CNC routers becomes more widely available. What woodworkers once had to pay for a small-sized router will now buy them a full-sized, 4×8 CNC router.

The projects that suddenly become possible with a router of this size are impressive. These machines are capable of handling a full sheet of plywood which makes material prep a breeze. Whether you are a hobbyist woodworker or run a professional woodworking shop there are a ton of possibilities with these CNC routers.

Custom made cabinets, camper van build-outs, business signs, and huge art pieces are all CNC projects that are possible with a full-sized CNC.

What to Look for in a 4×8 CNC Router

When you start the search for a new wood CNC router there are a number of considerations to take in mind. Here are a few things to look out for.

Machine Size

Despite the cutting area being 4 ft by 8 ft on all of these machines, their size and footprints can still vary by quite a bit.

Compare, for example, the Zenbot 4×8 CNC router to the Grizzly G0895 4×8 CNC Router. The Zenbot comes in with a footprint of 108″ x 60″ and weighs approximately 400 pounds. While the Grizzly has a footprint of 124″ x 84″ and weighs 2,500 pounds.

Granted these are very different levels of CNC machines but space and weight have to be a consideration for getting them into your shop and how much weight your space can hold.

Power Requirements

4×8 wood CNC machines are offered in a variety of power options. These go from your normal, household 110v socket all the way up to 220v 3-phase power.

While 110v and 220v outlets are found in most wood shops, or at least can easily be run, 3-phase power usually is only found in industrial locations.

3-phase converters are available to add on to your existing power supply and some of these CNC machines even come with converters already built in. But there will be a little more work and cost involved with going that route.

Hold Down Capabilities

The most basic level 4×8 CNC routers will come with no built-in hold down capabilities. That means either screwing your workpieces directly into the spoil board, installing your own t-track system, or installing an aftermarket vacuum pump system.

Many of the higher end CNC routers come with a vacuum clamp system built in. In a production environment, a vacuum hold down system is certainly the way to go as it will minimize waste and speed up processing time dramatically.

Build Quality

In looking at the price ranges of the available 4×8 CNC routers it is pretty obvious that build quality is going to be all over the place.

With that said I don’t think any of these CNC routers are bad machines. Some are just geared for more of a hobbyist environment where they don’t get frequent use and tolerances may be a bit more forgiving.

In production environments where these machines will be running all day, every day then build quality is obviously a huge deal. You’ll want to be looking for systems that are prebuilt with solid steel frames. Not only can these machines handle more abuse but they also run at far higher speeds which dramatically increases productivity.


Some of the hobbyist level 4×8 CNC packages will be built to work with standard palm routers. Others are supplied with liquid-cooled, CNC grade spindles that are both quieter and capable of handling a much higher workload.


The speed at which the router can both cut and traverse across the table are a bit factor in how productive your CNC can be.

Cut speeds can range from 200 IPM (inches per minute) to over 2,000 IPM on the higher-end models. Traverse speeds can also vary dramatically and that is not insignificant when working on a large, 4×8 surface area.


CNC routers are offered both with or without a built-in controller system. The controller is used to manually move the spindle head for setting up new cuts.

Routers with a built-in controller also typically offer flash drive or memory card connectivity so you can download cut patterns directly to the machine. Others require a computer to be connected directly to the CNC to set up new cut paths.


Prices for 4×8 CNC routers can range from $3,000 at the low end to easily over $30,000 for well-equipped packages that include upgraded routers, vacuum pumps, etc.
