Computer Numerical Control (CNC) machines are great for projects that require precision and repeatable cuts. Until recently, CNC machines were too large and expensive for consumer use. But that’s not true anymore. Here are five CNC machines you can own.
What to Look for in a CNC Machine
CNC machines come in many shapes, sizes, capabilities, and at many price points. This is one of those cases where spending more typically gets you a higher quality machine or more features.
One of the first things you should ask yourself is what you want to accomplish with a CNC machine. If your goal is to engrave small projects with a logo, then a super-expensive, large machine is overkill. Likewise, if you want to make a guitar body, then a small cheap one won’t do. So, here are a few things to look for:
- Size: The size of the machine limits (or expands) your projects. CNC Machines for the home typically consist of a woodworking router on a rail system that moves around a bed (where you put your wood or other material). The larger the bed, the bigger the project you can tackle. The size also determines the weight of your CNC router, and that’s something to keep in mind. Larger machines sometimes weigh over 100 pounds, so you need a sturdy surface to hold one.
- Software: All CNC Machines require software to work. So, you should check which Operating Systems the CNC machine is compatible with, and which programs it uses. Some CNC software, like GRBL, is easier to use than others. Other programs might require more effort to learn or cost some money. If you aren’t sure what to use, check to see if the CNC router comes with free software—that will give you a starting point.
- Ease of maintenance: Much like 3-D printers, you have to do some maintenance on a CNC machine occasionally. And sometimes, parts wear down or break. On the more expensive CNC machines, you should be able to purchase replacement parts and repair your device as necessary.
- Assembly difficulty: Most, if not all, CNC machines arrive disassembled. Depending on the number of pieces, the size of the machine, and the tolerances involved, you might find assembling your new CNC router difficult. It’s not uncommon to need several hours over multiple days to put together a new CNC router.
Best Overall: BobsCNC E4 CNC Router
The BobsCNC E4 CNC router is a machine that maximizes what you get for what you spend. Other machines with a similar bed size cost hundreds of dollars more. You’ll have plenty of space to work on your bigger projects.
This machine uses a DeWalt router as its cutting tool, but you have to buy bits separately. Unlike most of the other CNC machines on this list, the main structure of this device is wooden. Most CNC routers rely heavily on steel. The benefit of its wood design is weight. Despite being one of the larger CNCs we recommend, this machine weighs just over 40 pounds. So, you can use something other than your sturdiest table to hold it.
BobsCNC is compatible with Windows, macOS, and Linux, and nearly every common CNC software available. It doesn’t come with free software, but you can use a free option, like GRBL. You have to assemble the CNC router, however, so expect that to take several hours, if not longer.
BobsCNC E4 CNC Router Engraver Kit with the Router Included (610 mm x 610 mm cutting area and 85mm depth of travel)
This CNC Machine includes a larger workspace than most at its price point. It’s light, and you get a nice DeWalt router cutting tool, too.

Best Budget: Genmitsu CNC 3018-PRO
If spending several hundred (or over one thousand) dollars is outside your budget, the Genmitsu CNC 3018-Pro might warrant your attention. Its drastically smaller size and cheaper woodworking router considerably bring down its cost.
