Best 4x4 CNC Routers [2021] for Hobbyists & Businesses

If you are a hobbyist, maker, or small business owner looking for a CNC that has a cutting area of 4'x4', this guide will help you pick the one you need.

The key advantage to buying a 4x4 CNC router is that it gives you the ability to work on 4x8 sheets at a much lower cost compared to a full-fledged 4x8 CNC machine.

This is achieved using a software feature called tiling.

As a 4x4 CNC has to travel 4' length in X and Y directions, the linear motion components need to be seamless and the frame should be rigid enough for that long travel.

Considering all the important factors for a 4x4 machine, I chose the best high-quality 4x4 CNC routers on the market for this guide.

There is quite a variation in the prices of these machines due to the differences in speed and accuracy.

I break everything down for you so that you can make a wise choice.

Quick summary of Avid CNC PRO4848

Avid CNC is a US-based CNC brand that specializes in CNC routers for serious hobbyists and small businesses.

Avid offers two products with a 4x4 cutting area, the CRP4848, and the PRO4848.

I chose the PRO4848 for the extra speed and power it offers.

Also because I think the price difference between the CRP4848 and PRO4848 is not that significant.

Avid CNC is designed to be modular so that you can start out small and then add upgrades later to meet your demands as they grow.

This means you can convert this 4x4 CNC router from Avid into a 4x8 CNC router or a 5x10 CNC router later by only adding the extra components.

This expandability is a major advantage to buying the Avid CNC compared to a welded frame CNC.

The NEMA 23 version of this CNC Router with standard gantry and 8” of Z travel will cost around $4,725.

The frame for the NEMA 34 version will cost $100 more.

However, this will only contain the framework and linear motion components.

You will have to purchase stepper motors, spindle, electronics, and controllers separately.

You can purchase these additions from Avid CNC or else you can use components of your choice.

Avid CNC provides everything else you need as a bundled kit to make buying easy.

Size and Build

PRO4848 CNC Router has a 49-½" x 49-½" work area with a footprint of 67” x 65 ¾” x 43 ⅜” and weighs around 313 lbs.

This means you have the space to work with a 4'x4' sized sheet.

You can also mill a 4'x8' full-sized sheet on this CNC as the sides of the bed are open.

The best way to do this is by a technique called tiling.

For using the tiling technique, you need a CAM software that offers that functionality like the Vectric Aspire CAM.

However, tiling does reduce your efficiency a bit as you have to manually move your sheet material after it's done with one half.

For full efficiency, you need a dedicated 4x8 CNC router like the Avid CNC PRO4896.

If you get the optional leg kit with the PRO4848 the overall height increases to 77 ½” and the weight becomes 377 lbs.

You can also add a secondary Z-axis on an Avid CNC PRO which lets you use two tools without the need for a tool change.

This will need you to have an extended gantry that adds 10” to the X-axis footprint. However, the available work area would still remain the same.

If you want to make or use a table of your own, you will have to provide a table that is strong and rigid.

This is because the motion in Avid CNC is quick which can cause substantial jerks/vibrations in the entire setup.

You will need a rigid table to withstand and prevent jerking.

You can cut materials with a maximum thickness of 8” on the Avid CNC PRO 4848 and if you were to shell out around $150 more you can use the increased Z-axis travel of 12”.

The frame is made of heavy-duty aluminum and steel plates which provides it excellent rigidity and allows you to cut hard materials fast.

Aluminum CNC milling is quick and easy on the Avid PRO4848, and you can find several tutorial videos on YouTube showing you how this machine performs with Aluminum.

Milling steel is also a possibility, but if steel milling is a main part of your workflow, then this machine is far from ideal.

You need either the Avid benchtop pro or a proper benchtop CNC mill.

Linear Motion

The X and Y axes use a rack and pinion drive mechanism that is fast and accurate when compared to other drive mechanisms.

The key advantage of a rack and pinion drive system is the high speed it offers compared to screw drive systems.

Rack and Pinion systems deliver this high speed without compromising on accuracy.

The gantries slide on precision-made profile linear guide rails that add to the overall rigidity of the machine.

The X and Y axes have a resolution of 0.0005”.

The Z-axis is driven by a precision ball screw mechanism which gives it a resolution of 0.0002”.

It has an accuracy of 0.005” or better and repeatability of 0.002” making it an excellent choice for high precision jobs.

The rapid speeds on Avid CNC Pro4848 are 500 ipm for the NEMA 23 version and 1000 ipm for the NEMA 34 version.

You can achieve a cutting speed that is around half of the rapid speeds on both variants.

This is the biggest advantage of Avid CNCs because they are astonishingly fast compared to almost any other CNC under $10k.

Spindle

The default package does not come with a spindle and you will have to purchase one from Avid CNC or any other manufacturer.

Avid CNC offers a 4 hp and 8.7 hp spindle for the Pro 4848. The 4 hp spindle costs around $1,995 and the 8.7 hp spindle costs roughly $3,995.

Additionally, you will have to spend $116 for the 4 hp spindle mount and $140 for the 8.7 hp spindle.

The 4 hp spindle has an ER20 collet that can hold tools with a maximum shank diameter of ½” and the 8.7 hp spindle has an ER32 collet with a capacity to hold ¾” shank tooling.

The depth of cut for the 8.7 hp spindle is 2.3 times that of the 4 hp spindle for the same speed, tool, material, and feed rate.

Both of these spindles come with a Delta VFD for speed control and is a plug-and-play system.

An upgrade that you should consider if you run a business, is the S30 ATC spindle upgrade from CNC Depot.

This is a third-party spindle upgrade for Avid CNC machines that converts the single tool spindle to an Automatic Tool Changer.

If you buy the S30, you don't need to buy the spindle from Avid CNC, however, you'll need to buy the spindle mount.

Having an ATC can dramatically improve production if you constantly work with multi-tool projects.

Controller and Electronics

Plug and play control system from Avid CNC
Plug and play control system from Avid CNC

Avid CNC has two controller options to choose from, either a NEMA 23 build or the NEMA 34.

The NEMA 23 motors have a torque of 420 oz-in and the NEMA 34 motors have a torque of 960 oz-in.

Avid CNC Pro4848 uses two motors on the X-axis to improve accuracy and prevent racking.

An industrial-grade NEMA enclosure is used for housing the controller and drivers which allows this CNC machine to have an industrial-grade machine appeal.

The controller uses an ethernet smooth stepper that is fast due to parallel processing and is compatible with various software and operating systems.

The controller has support for several electronics hardware like limit switches, E-stop buttons, and Z-probe.

The electronic hardware and cables from Avid CNC are designed to be plug and play and do not require you to solder or crimp them.

Software

The most used control software for Avid CNC Pro4848 is the Mach4 software.

Mach 4 can give you industrial-grade precision and control and is quite fast when compared to other control software programs.

Mach 4 software costs around $200 for a lifetime license and it can work offline without the need for an internet connection.

Sadly, it runs only on Windows OS computers.

Note that if you buy the Plug and Play CNC Control System from Avid, Mach3/Mach4 is your only compatible choice.

In any case, going with GRBL based control is less than ideal here as it prevents you from adding a 4th rotary axis down the lane.

A rotary axis is really useful for woodworkers for CNC turning pens, spindles, or any rounded products.

Assembly

As it is a customizable machine you will have to assemble each part and it can take you a whole weekend to put it together.

The assembly instructions are clear and detailed, with well-illustrated images for reference.

Community and Support

The customer support is US-based and is prompt and reliable in providing you assistance from assembly to any issues that you may face while running.

Avid CNC provides a one-year warranty on all its mechanical and electronics products.

This CNC has stood the test of time and is highly popular among woodworkers and people who work with 4' sized pieces.

If you run a business, this CNC is my top recommendation for a 4x4 CNC Router.

For linear motion, 8mm stainless steel lead screws are used that are rigid and have good accuracy. The use of thrust bearings reduces the vibration and improves the smoothness of linear motion.

The gantries move on V-slot extrusions using polycarbonate V-wheels.

One good thing about V-wheels is they do not require frequent lubrication like other mechanisms.

Workbee uses four NEMA 23 stepper motors with holding torque of 175 oz-in for moving the axes.

The Y-axes use dual-drive wherein two stepper motors are used, one on each side to prevent racking. 

You can achieve a maximum feed rate of around 98 ipm with an accuracy of around 0.0039” on the Workbee Z1+.

Spindle

Workbee does not come with a spindle, you can select one of the routers that they have to offer at the time of purchase.

You can also use a spindle or router of your choice. Make sure you add or purchase a proper mount for the spindle/router you choose.

One of the router options that Ooznest offers is the 1,000 W Mafell router. It has a variable speed that ranges between 4,000 RPM and 25,000 RPM.

It has a ¼” collet and is silent and more powerful than the 710 W Katsu router that Ooznest offers.

Additionally, the router comes with a one-year warranty.

If you are adding a router to your kit, make sure you select the appropriate socket plug as these routers come with US and EUR plugs.

Controller and Electronics
