When I first stepped into the world of CNCs, I was overwhelmed by the many software programs used in the process.
I wanted to figure out how these software programs worked and which software was best for a particular purpose (like hobby CNC and Production CNC work).
Here I walk you through all the best software choices for CNC routers and explain the advantages and disadvantages of each.
In a CNC machining process, there are four kinds of software involved. These are:
- Computer-Aided Designing (CAD) software: Creates 2D, 2.5D or 3D designs
- Computer-Aided Machining (CAM) software: Converts the designs to G-code, a language understood by machines
- Control Software: reads the G-code and creates signals to control the stepper motor drives
- Simulation software: reads the G-code and predicts errors that may arise while machining
However, many software programs can do more than one function among the four.
There are dedicated software programs for each of these functions, but there are all-in-one software bundles that do everything as well.
After carefully considering the ease-of-use, reliability, compatibility, and community support, I have put together a list of some of the best software for your CNC application.
Some of these software are paid while some are free. The free ones are mostly Open-Source CNC software.
I have also categorized them so that its easier to understand what each software does.
What's in this review?
Best All-in-One Software for CNC Applications
These software programs have the functions of CAD, CAM, control, and simulation software rolled into a single package.
An all-in-one software can save you a lot of time and money.
Quick Summary of Easel Software
The Easel software from Inventables is a truly all-in-one software which lets you do everything from CAD, CAM, and Control within a single software.

|Carbide Create||Yes||Yes||Only with Carbide 3D CNCs||Yes||Free|
Quick Summary of Carbide Create Software
If you want a do-it-all software, Carbide Create is a good choice. It combines CAD, CAM, G-code Sender and simulation capabilities into a single package.
Carbide Create was made by Carbide 3D, the makers of the famous Shapeoko CNC machine, and hence it was designed keeping the needs of hobbyists in mind.
It is simple to use, and you are not required to have any CAM software expertise to run it. You can import DXF and STL files to create G-code.
You can create 2D shapes directly from Carbide Create and convert them into G-code and use it to control your CNC machine.
Carbide Create is free to use and is compatible with Windows and MacOS operating systems.
Carbide Create can do 2.5D machining. For 3D machining, you can use MeshCAM, which is a paid software but quite powerful.
2.5D machining is when you can move two axes simultaneously ( x and y) and move the third axis (z-axis) while the other two axes are still.
In 2D machining, you can move the x and y-axis together or independently. In 3D machining, you can move all three axes simultaneously or independently. So 2.5D lies somewhere in between 2D and 3D machining.
Carbide Create is a good all-in-one solution for Shapeoko users and a great CAD+CAM solution for non-Shapeoko users.

Best CAD Software for CNC Applications
The first step in CNC machining is creating the model or designing. Here I talk about the best design software choices for CNC routing/machining.
1. VCarve Pro
Quick Summary of VCarve Pro Software
Vectric's VCarve Pro is a CAD plus CAM solution for CNC machining.
Unlike other CAD modelling software like Fusion 360 and solidworks which have broad functions, Vectric makes software exclusively for CNC work.
This means there are more specific features and tools for CNC work in VCarve Pro compared to the others.
This software lets you make 2D and 2.5D models with which you can generate toolpaths (CAM) using VCarve itself.
Some of the features offered include 2D designing, image tracing from an existing photo, trueshape nesting (for optimum space use).
CAM features offered are toolpath generation for Machining, pocketing, drilling, inlays, threading and engraving.
VCarve Pro sells at $700 for a single license.
The only missing feature in this CAD plus CAM solution is 3D modelling.
Although you can import 3D models into VCarve Pro, to do 3D modelling you will need Vectric's Aspire software.
In CAM, the 2 sided machining feature is really handy for machining two sides of an object in a single session.
VCarve Pro does not have adaptive milling in it's CAM module and that's a key difference from Fusion 360 which has adaptive milling.
Adapative milling is a really useful feature for metal machining that helps to maintain a consistent chip load and ultimately higher accuracy.
Vectric has brought out dozens of free videos that teach you how to use the software with your CNC machine and this is a great advantage for beginners.
This software is easier to learn and has a much lower learning curve compared to Fusion 360. However that also limits the capabilities a bit.
There is a free unlimited trial offered for this software which lets you test its features except saving toolpaths and exporting functions.
Vectric brings out newer versions of their software occasionally and to do the upgrade, you need to pay an upgradation fee.
Vectric has a highly active user base. The community at the vectric forum can be really helpful for learning and troubleshooting.
Overall, VCarve Pro is a great tool for CAD modelling and CAM toolpath generation if you're working wood, aluminum and other non-ferrous metals.

AutoCAD has a very large user base and has a subreddit that you can use for troubleshooting. It also provides user-friendly and reliable official support.
Best CAM Software for CNC Applications
Controller software and motion controllers cannot read 2D or 3D design files. The design file needs to be converted into direction and speed commands called G-code.
CAM software takes in the design files (e.g. STL, DXF) and converts them into G-code.
This G-code is then used by the control software to output signals that result in the movements of the CNC.
Although there are CAD plus CAM solutions like Easel and VCarve Pro, there are advantages to using dedicated CAM software.
The following software programs are considered as the best dedicated CAM software programs on the market.
1. Mesh CAM
Quick Summary of MeshCAM Software
Mesh CAM is a paid CAM software developed and sold by GRZ software.
This software is almost a plug-and-play solution, which highly reduces the amount of machining knowledge you need to know.
The software chooses most parameters automatically based on the quality level that you pick.
For an experienced machinist, this means there's less freedom to customize while for beginner's it makes things really simple.
MeshCAM accepts STL and DXF files from all 3D CAD programs.
If you have a 2D file, then MeshCAM lets you load the file into it and extrude the 2D drawing into a 3D model. This 3D files is then used to generate toolpath.
One highly popular feature of MeshCAM is that it can convert a JPEG image into a machinable 3D file. Which makes things much quicker by not having to model it in CAD first.
MeshCAM is sold in two versions, MeshCAM and MeshCAM PRO. The standard version sells for $250 while the PRO version is sold at $500 for a single license.
MeshCAM Pro offers a toolpath simulation tool apart from all the features in the standard version. This helps in identifying any errors before doing the machining.
Although the single license is intended for a single user, MeshCAM allows you to install it in up to 3 computers.
The Nomad 3 CNC from Carbide3D uses MeshCAM as its default CAM software for 3D models.
MeshCAM claims to have more toolpaths than all other competing CAM software and that makes it easy machine even highly complex parts using this software.
2-sided machining is made easy in MeshCAM due to a feature that lets you add support/tabs on the sides of the stock without needing a vise.
These tabs greatly help in keeping the stock zeroed and also helps hold down the part after its flipped over for machining the other side.
MeshCAM can run on both Windows Os and Mac OS.
If you're unsure of whether MeshCAM is the right fit for you, they offer a 15 day free trial for their software.
GRZ software offers email support for any queries related to MeshCAM for their customers.
Overall, MeshCAM is a great, quick and easy CAM solution for most kinds of CNC machining work.
Quick Summary of CamBam Software
CamBam is a CAM software made by HexRay Ltd. and is highly popular among CNC users.
This software is a paid one and sells at $150 for a single license.
CamBam has all the CAM features you need for any CNC machining task.
Unlike MeshCAM, CamBam is less the plug-and-play type and requires you to manually choose several parameters which MeshCAM chooses for you.
This means there is a learning curve with CamBam compared to MeshCAM which doesn't required much knowledge of machining.
However, if you're someone who loves to manually set each parameter and wants full freedom with your CAM software then CamBam is a great choice.
In comparison with MeshCAM Pro, CamBam doesn't have a inbuilt toolpath simulator, but CamBam is much cheaper in comparison.
You can use a separate simulator like NC viewer which is free, for simulation.
A major drawback of CamBam was that it did not support spline editing. Now CamBam support spline objects as well in its CAM software.
CamBam offers a free trial which lets you run 40 sessions with all the features to test everything.
Unlike MeshCAM which works with a Mac OS, CamBam works only with a Windows OS.
Also, a lot of users prefer MeshCAM for 3D milling whereas CAMBAM is preferred if the primary use is to do 2D and 2.5D milling.
Overall, if you want more control over your CAM work and not a plug-and play solution then CamBam is a good choice.
Quick Summary of Estlcam Software
Created in 2014, by a German software Enigneer named Christian Knüll, Estlcam is the most simple and least expensive (except the opensource Openbuilds CAM) option in this list of CAM software.
Estlcam lets you do 2D and 3D toolpath generation by cutting out all the complexities for a quick operation.
At $60 for a single license, Estlcam is truly a hobbyist friendly CAM software.
What is remarkable about Estlcam is the much lower learning curve and quick turn around times which a lot of hobbyists prefer compared to the bulk of other CAM solutions.
Many beginners in CNC work use Estlcam as their first CAM software to learn CAD and CAM and then later opt for pricier software after they learn the trade.
Estlcam offers a limited time free trial with all the features for you to test before buying it.
This CAM software runs only on windows OS and not on Mac OS.
There is no dedicated forum for Estlcam, however this software is really popular among users of Mostly Printed CNC (MPCNC) and their forum has an active community of Estlcam users.
Overall, this is a good choice for a hobbyist who's looking to make quick inroads into CNC work, but as you learn and your requirements change you might feel a bit limited.
|Openbuilds CAM||No||Yes||Yes (with Openbuilds Control)||Free|
Quick Summary of Openbuilds CAM Software
Openbuilds CAM is a free web based CAM software made and supported by the creators of the online community Openbuilds.
Now, Openbuilds is an end to end CNC manufacturing company which sells their own machine kits and software.
True to the philosophy of the open source maker movement, the software made by Openbuilds is free and open for use to anyone.
Openbuilds also makes the openbuilds control which is a G-code sender software which I have talked about below in the Control software section.
One important drawback of Openbuilds CAM is that it only works with Openbuilds Control G-code sender and you cannot use any other control software.
However once the G-code is input into Openbuilds control you can send it to any GRBL based controller board.
This CAM software needs an active internet connection to work.
The great thing about Openbuilds software is the community around it who have great experience in using and troubleshooting it.
Instead of support from a brand like with MeshCAM you get support from the Openbuilds community, which is expected as its a free software.
Overall, this is a good CAM software for hobbyists and people who love the simplicity of a free software and the great community behind it.
Best Controller Software for CNC Applications
The G-code generated by the CAM software is fed into an interface between the computer and the control board of the CNC.
This interface softaware is used to send the G-code from the computer to the CNC controller board. Therefore this interface is also called as a G-code sender.
Some examples of stand-alone G-code senders include Universal G-code sender (UGS), GRBL Candle, and bCNC.
The G-code that's received in the controller hardware is interpreted by the firmware that's installed in the control board.
The firmware then instructs the board to send out signals that result in the motion of the CNC.
Examples of standalone firmwares include GRBL, Marlin.
GRBL is generally used in Arduino based controllers.
I talk in detail about the best GRBL based controller here-Best CNC GRBL Controllers for Hobbyists.
Now, there are software programs that can do both the g-code sending and interpreting tasks.
These all-in-one control software do all the tasks that's to be done after g-code is generated. Examples include Mach3, Mach4, LinuxCNC, PlanetCNC.
All-in-one control software
These software programs do the process of sending the G-code as well as interpreting the G-code for outputting signals for motor movement.
You don't need a separate controller firmware or G-Code sender if you use these sfotware.
1. Mach 3
|Mach3||No||Yes (with LazyCAM add-on)||Yes||Paid|
Quick Summary of Mach3 Software
Mach 3 is a control software that you can install on a 32-Bit Windows PC to control the motions of your CNC machine through a graphical user interface.
You can either import the G-code from your CAM software to Mach 3 for machining or use the LazyCAM add-on to convert DXF, BMP, JPG, and HPGL into G-code.
With the LazyCAM add on, Mach3 can be called as a CAM plus Control Software that does everything except CAD modelling.
For Mach3 to work the computer should be connected to the CNC using a parallel port cable.
You cannot directly connect to the CNC via USB when running Mach3 (Unlike GRBL). This is because Mach3 runs in real-time and USB does not support real time access.
A workaround to this is to use a breakout board like Smoothstepper as an intermediary.
Smoothstepper has a parallel port end which connects to the CNC and the other end that connects to the computer can be a USB or ethernet port.
The USB version is called as a USB SmoothStepper (USS) and the ethernet version is called Ethernet SmoothStepper (ESS).
In the absence of the breakout board, Mach3 turns the host computer into the motion controller.
However, a breakout board is highly recommended as it results in much lower latency and immunity from electrical noise compared to connecting directly from the computer.
Mach 3 can control a maximum of 6 axes and is compatible with several breakout boards.
It also provides a wide range of customizability for the user interface and a collection of operations through the wizard. You can use these to create the most common designs without the need to generate G-code.
Mach 3 is a paid software, but you can use the demo version, which has several limitations on functions and the number of lines of code.
You can purchase a single license and use it on multiple machines if you are a hobbyist.
The license for Mach 3 will cost you roughly $175 and can be purchased from their website.
Mach 3 has a large user base. Therefore you will be able to find solutions to most of your problems online. However, the official updates for Mach 3 have been stopped.
The software has a simulation mode that unlocks all the features. However, you’ll have to uninstall the parallel port drivers to enable it. Meaning you cannot control the CNC machine while simulation mode is enabled.
2. Mach 4
|Mach4||No||Yes (with LazyCAM add-on)||Yes||Paid|
Quick Summary of Mach4 Software
Mach 4 is designed for newer computers and works using the USB port to connect to your CNC machine via a motion controller.
It has a better graphical user interface than Mach 3 and can handle large files. Hence Mach 4 requires 512 MB of Video Card and 1 GB of RAM.
Mach 4 is priced at $200 for the hobbyist version and can only run on a single PC, the ID of which should be mentioned while obtaining the license.
For industrial use, the Mach 4 will cost you around $1400.
It has a remote link that you can use to control and monitor your CNC machine remotely.
It has a modular design, meaning you can easily add, remove or create features and provide great customizability. Sadly, it runs only on Windows, just like Mach 3.
Control software acts as the interface between your computer and the controller of your CNC machine. It reads the G-code instruction and converts them into commands that the breakout board can understand. It can also be used to manipulate your CNC machine manually.
Quick Summary of LinuxCNC Software
LinuxCNC is a control software developed using the open-source Linux platform and hence is a free CNC software.
LinuxCNC has been around for a long time and has been used to develop other software such as the Mach 3 software on this list.
It can control up to nine axes simultaneously. However, a USB interface is not recommended as USB communication is slower in transferring instructions than parallel ports.
LinuxCNC can only be run on PCs with the Linux OS installed, and the system requirements are low. You can even run it on Raspberry Pi4 and above.
It uses the parallel port on your computer to interface with your CNC machine. You can also use the ethernet port to interface your machine via ethernet breakout boards (the most popular ones are from Mesa).
Just like Mach3, LinuxCNC converts the host PC into the motion controller and does not need necessarily need a breakout board.
However, using an ethernet card (such as mesa) helps in hardware step generation and encoder counting rather than using just a parallel port cable.
The most popular choice of ethernet card for LinuxCNC is the Mesa 7i76e.
LinuxCNC has a large online community, and the software itself has a forum-like feature that lets you post questions to other users around the globe.
It has a graphical user interface that is highly customizable, and it supports touchscreen interface devices and pendant controllers.
|PlanetCNC||No||No||Yes (only with PlanetCNC hardware)||Free|
Quick Summary of PlanetCNC Software
PlanetCNC is a free CNC machine control software that you can use to control your CNC machine using G-code.
However, PlanetCNC is a combined hardware and software solution. The control software works only with the CNC USB controller Mk3/4 hardware that's sold by PlanetCNC.
The software comes free with the hardware.
Unlike LinuxCNC and Mach3, PlanetCNC has a USB connection between the Mk3/4 controller and the computer.
This controller is then connected to stepper drivers. If you don't want to use separate stepper drivers, PlanetCNC sells their Mk3/4 board with integrated steppers as well.
If you wish to connect this controller to a parallel port stepper driver like Gecko, you need to buy the DB25 adapter that's sold by PlanetCNC.
In addition, PlanetCNC has CAM software capabilities as well. You can import DXF, NC Drill (Excellon) files, PLT/HPGL files, Gerber files and convert them into G-code.
Apart from generating G-code, you can also edit the G-code you have imported and scale the design according to your workpiece size.
You can run it on 64 and 32 bit Windows, MacOS(High Sierra or higher), 64 and 32 bit Linux, RaspberryPi 3 and 4.
The interfacing with the motion controller can be via USB or ethernet.

CNC Controller Firmware
These are software that are run only on the controller hardware of the CNC. Usually the user does not interact with the firmware and that's done through another GUI like UGS, GRBL Candle or Openbuilds Control.
Quick Summary of GRBL Firmware
GRBL is an open source firmware that controls Arduino ATmega328P boards (Arduino Uno).
This firmware is connected to the computer through a USB connection and does not need a parallel port, which is a major advantage.
It's a free, open-source firmware that was developed over the years primarily for CNC milling.
The current version of GRBL is v1.1.
GRBL currently allows only up to 3 axis control and that's one limitation of this firmware.
GRBL_HAL and GRBL_Esp32 are variations of GRBL that have been developed for 32 bit boards unlike GRBL which works only with 8 bit boards.
GRBL is highly used in budget CNC machines (like desktop CNCs) and in DIY CNC builds by hobbyists. Primarily due to the popularity of Arduino.
Almost all 3018 CNCs available on the market use GRBL plus UGS combination as the controller software.
Well known CNC brands that use GRBL based controllers include Carbide 3D, BobsCNC, Openbuilds and Spark Concepts.
There's a large community of people who contribute to GRBL and that helps in the constant development of the software.

Factors to consider while choosing a Software for your CNC Application
1. Capabilities and Features
It is important to know your application with the software. For example, if you want complex designs, you will require a dedicated design software.
If you intend to do basic milling operations, a 2D CAD will be sufficient, whereas if you plan on doing 3D relief carving on wood, you would require 3D design software such as Solidworks or AutoCAD.
Most CAM software clearly list the features which are supported in them. E.g. for metal milling, adaptive milling is a great feature to have in the CAM software.
A controller or simulation software has a fixed number of axes that it can control, so choose a software that can accommodate all the axes of your CNC machine.
2. Learning Curve
Operating any machinery or software requires certain skills, and therefore, it is necessary to consider the skills required to use the software.
If you intend to use a professional software like AutoCAD, you need to understand the basic design principles and spend some time learning the software.
On the other hand, software like Easel provides you with a simple design interface where you have access to pre-designed shapes that you can combine to create your designs.
But then again, it all depends on the level of perfection and detail you want to achieve.
Open-source software like LinuxCNC and Inkscape are free to use. You should consider the functions required to create the product and check whether free software can provide them.
Paid software provides better official customer support and has a variety of specialized functions, and can be easy to use owing to innovative features.
It is easy to overpay for software with several bells and whistles, but if they were to serve no real purpose for you, the expenditure would be a waste.
4. Subscription v/s Perpetual License
Licensing is to be considered carefully. Do you want to pay a certain amount every year or do you want to pay a one time flat fee.
Although, even software with perpetual license might charge you for version upgrades like the Vectric VCarve Pro.
5. Cloud based v/s Non-cloud based
If you work in your garage or at a place where it's difficult to get a good WiFi signal, then the performance of a cloud based software will be questionable.
In such a case, you should opt for a software which does not require an active internet connection to work.
6. Active Community
You'll most likely run into issues at least occasionally when using CNC related software. This is because there's a lot of variation in the application requirement of each person.
An active online community can help you with troubleshooting and queries. An alternative to this is to have the vendor's customer support answer your queries.
If your chosen software doesn't have an active community, then it should at least have excellent tech support from the vendor.
Multipurpose or Dedicated CNC Software?
Multipurpose software are best suited for small production runs with simple designs.
The sole purpose of dedicated software is to improve the quality and ease of production of complex parts.
If you need intricate designs and perfect control over your production runs, you may choose dedicated software for each purpose as they provide you with better quality at each step.
If you are a hobbyist or DIY enthusiast, an all-in-one CNC software would be easy to use and learn.
