Quick summary of Avid CNC PRO4824

If there is a 2×4 CNC router that balances performance and price perfectly then it’s this CNC router.

The Avid CNC PRO4824 is perfect for small businesses that need to move volume at an affordable cost.

PRO4824 CNC kit has to be bought along with the recommended electronics kit, software, and accessories.

Avid CNC lets you choose components and custom-build your CNC router, and your final price will vary considerably depending on the components you choose.

Size and Build

The PRO4824 CNC router kit has a 40 ¾” x 67” footprint that gives you a cutting area of 49 ½” x 24” with a standard Z-axis travel of 8 inches.

Avid CNC offers extension kits to expand the frame of PRO4824. You also have the option to increase Z-axis travel up to 12 inches. 

You can use a spoilboard or vacuum hold down to make the workbed for workpiece holding.

Its chassis is made of heavy-duty aluminum extrusions and steel components, which give the CNC a solid foundation for challenging projects.

The gantry of PRO4824 has a width of 67 inches, which can be extended to 77 inches at an extra cost. The extended gantry is helpful for dual Z-axis operation.

The best thing about Avid CNC routers is their modular design which lets you upgrade this 2×4 CNC router to either a 4×4 CNC router or 4×8 CNC router down the road by buying extra components.

Linear Motion

PRO4824 CNC router uses PRO rack and pinion with linear rails to provide linear motion in X and Y-axes, which gives you a resolution of 0.0005 inches.

Its Z-axis is ball screw driven and has a resolution of 0.0002 inches.

Rack and pinion drive systems give you incredible speeds while working without compromising precision.


Avid CNC offers two stepper motor versions to drive the axes of PRO4824, the NEMA 23 and the NEMA 34.

For light production work, I suggest the NEMA 23 type stepper motor.  Using Avid CNC electronics, you can get a maximum rapid traverse of 500 ipm and a maximum cutting speed of 250 ipm.

If your business requires high production rates, then a NEMA-34 type stepper motor is suitable for you. You can get a maximum rapid traverse of 1,000 ipm and a maximum cutting speed of 500 ipm.

Similarly, you have the option to choose between two spindles for the Avid PRO4824 CNC machine.

I suggest the 4 hp (3 kW) spindle for small businesses and the 8.7 hp (6.5 KW) spindle for maximizing production.

The 4 hp spindle has a material removal rate of 95 cubic inches per minute but the 8.7 hp spindle can remove material 2.3 times faster, so if you need to make deep cuts fast you should go for the larger spindle.

Both are plug-and-play VFD spindles and can be easily connected to the Avid CNC controller without any additional components.

Controller and Electronics

Avid CNC provides you the option to customize your PRO4824 router according to your production requirements.

You can either purchase the plug-and-play Avid CNC electronics kit or custom-build the electronics for the PRO4824 CNC machine.

Hobbyists and home-based businesses only need the Plug and Play NEMA 23 CNC Control System.

If time is a critical factor for you in your production process, get the NEMA 34 CNC control system for faster milling.

To complete the electronics build, you will need stepper motors with an appropriate controller, auto Z and corner finding touch plate, and Pepperl + Fuchs proximity sensor kit.

If you get the kit from Avid CNC, the controller, breakout boards, stepper motor drivers, and power supply modules are housed inside an industrial NEMA-type enclosure.


Avid CNC recommends Mach4 CNC motion control software for PRO4824 CNC machines.

Mach4 is an industrial-grade CNC control software and is quite responsive for use with large G-code files.

It is a robust software program and fast enough to provide instructions to make complex cuts quickly and allows you to control the CNC remotely.

Mach4 is compatible with computers running on Windows 7 or higher OS, and with the LazyCAM add-on, the software can perform CAM operations.

It has an easy-to-operate user interface. Additionally, you will get good community support to resolve your queries.

You can use any CAD/CAM software and use the G-code from it on Mach4.

Alternatively, you can use other popular software that can run ethernet Smoothstepper controllers like LinuxCNC.
