What Software Should I Use With My CNC Machine?

Choosing CNC software can be way more confusing than choosing the machine itself. Every program claims to make CNC easier, but some of them feel like you need to take a college course just to cut a rectangle.

The right software depends on what you want to make. Someone cutting basic SVG signs does not need the same program as someone designing mechanical parts or carving detailed 3D relief STL files. Your machine also matters because some programs can control the CNC directly, while others only create the G-code and require a separate program to send it.

Personally, I use Easel. It is not the cheapest option once you need its paid features, but it is easy to understand and I can normally get from a file to a finished toolpath without fighting the software for an hour. For me, that matters.

That does not mean Easel is automatically the best CNC software for everyone. There are cheaper programs, more powerful programs and programs that make a lot more sense for specific types of work.

First, What Kind of CNC Software Do You Actually Need?

Before comparing programs, it helps to understand that CNC software generally does one or more of three different jobs.

CAD or Design Software

CAD stands for computer-aided design. This is where you create or edit the artwork, vectors, dimensions or 3D model.

Inkscape, Adobe Illustrator and similar programs can create 2D vector files such as SVGs. Fusion can create precise 3D parts. Aspire and Carveco can build 3D relief artwork. Some CNC programs, including Easel and VCarve, also have built-in design tools.

CAM or Toolpath Software

CAM stands for computer-aided manufacturing. CAM software takes the design and decides how the CNC should cut it.

This is where you select the bit, depth of cut, feed rate, plunge rate, stepover and toolpath type. For a 3D relief carving, the CAM software may create a roughing pass with a larger bit and a finishing pass with a smaller ball-nose bit.

The CAM software then creates G-code, which is the set of instructions your machine follows.

CNC Control or G-Code Sender Software

The controller or sender connects to the machine and sends the G-code while the job is running. Depending on the program and machine, it may also let you jog the router, set the work zero, change speeds, pause the job and monitor its progress.

Universal Gcode Sender, CNCjs, OpenBuilds CONTROL, Carbide Motion, Candle, Mach4 and LinuxCNC are examples of controller or sender software. Which one you need depends heavily on your CNC and its controller.

Some programs handle more than one part of the process. Easel can design a project, create toolpaths and send the job to many supported machines from the same browser-based program. VCarve, Carveco, Fusion and MeshCAM create toolpaths and G-code, but you will normally use separate control software to run the machine.

The Quick Answer: Which CNC Software Is Best?

If you do not want to read the entire comparison, this is the short version:

• Best CNC software for beginners: Easel
• Best for an easy all-in-one workflow: Easel
• Best one-time-purchase option for serious router work: VCarve Desktop or VCarve Pro
• Best for creating your own 3D relief models: Aspire
• Best for artistic relief design without Aspire: Carveco Maker or Maker Plus
• Best for Carbide 3D machines: Carbide Create and Carbide Motion
• Best for mechanical parts and precise CAD work: Fusion
• Best for quickly turning an STL into G-code: MeshCAM

There is no single winner because these programs are built for different people. The easiest software is not always the most powerful, and the most powerful software is not always the smartest choice for the work you actually do.

Easel: One of the Easiest Places to Start

Easel is a browser-based CNC design, CAM and control program from Inventables. It is especially popular with X-Carve owners, but it supports many other CNC machines and can also export G-code.

Its biggest advantage is that it makes the entire process easy to understand. You set the material size, place or import your design, choose the bit and cut settings, preview the toolpath and start the carve. The interface is clean enough that a new CNC owner can usually make sense of it without watching 40 hours of tutorials.

Easel can import common formats including SVG, DXF, G-code and STL files. However, 3D carving and STL toolpath generation require Easel Pro. Easel's free and lower-priced plans can handle basic work, but the advanced features most serious users eventually want—including 3D carving and V-carving—are part of the Pro subscription.

That is the biggest downside. You are not buying the software once and owning it forever. You have to keep paying monthly, annually or through a longer subscription if you want continued access to those Pro features.

Would I rather not have another subscription? Obviously. I still use Easel because it saves me time and does not make every project feel harder than it needs to be. Software can be cheaper and still cost you more if you waste hours trying to figure it out.

Easel Pros

• Very easy to learn
• Design, CAM, simulation and machine control in one place
• Runs in a web browser
• Imports SVG, DXF, STL and G-code
• Easy roughing and finishing setup for relief carvings
• Works with many hobby CNC routers
• Good project preview and beginner-friendly workflow

Easel Cons

• 3D STL carving requires Easel Pro
• Advanced features require an ongoing subscription
• Not a full 3D modeling program
• Less control than advanced CAM packages
• Browser-based software may not appeal to people who want everything stored and run locally

Easel is a strong choice if your priority is getting projects onto the machine without becoming a CAM expert. It is especially good for signs, SVG projects, V-carving and purchased 3D relief files. It is not the program I would choose to design a complex mechanical part or build a detailed 3D model from scratch.

VCarve Desktop and VCarve Pro: Powerful Without a Subscription

Vectric's VCarve is one of the most popular CNC router programs for a reason. It handles 2D design, V-carving, 2.5D projects, toolpaths and imported 3D models in one program. Unlike Easel Pro, VCarve uses a traditional license that you buy and keep. Major future upgrades may cost extra, but the version you purchase does not stop working because you quit paying a subscription.

VCarve Desktop and VCarve Pro share the same basic workflow and can both import common 3D model formats, including STL files. The biggest practical difference is job size and production features. VCarve Desktop supports job sizes up to 24 × 24 inches without tiling. It can cut larger projects by dividing the toolpaths into tiled sections, while VCarve Pro allows unlimited job sizes directly and adds tools such as nesting, templates and other features aimed at larger machines and production work.

If you own a 4 × 2-foot or 4 × 4-foot CNC router, VCarve Pro is normally the version that makes sense.

VCarve is more powerful than Easel, but it also takes longer to learn. The interface contains far more buttons, settings and toolpath options. It is still much easier to understand than some engineering-focused CAD/CAM programs, and Vectric has a large training library and user community.

VCarve Pros

• Buy it once and keep using that version
• Excellent for signs, inlays, V-carving and general router projects
• Imports and machines 3D relief STL files
• Detailed control over tools and toolpaths
• Strong simulation and preview tools
• Large user community and extensive tutorials
• Easy upgrade path from Desktop to Pro

VCarve Cons

• Higher upfront cost than basic software
• More complicated than Easel
• Requires separate machine-control or G-code sender software
• Can import and machine relief models, but it is not a complete 3D relief-modeling program
• Desktop is limited to 24 × 24-inch jobs unless you divide larger projects into tiled sections

VCarve is a great fit for someone who has outgrown entry-level software, uses a CNC router regularly and would rather own the software than keep paying a monthly subscription.

Aspire: Best for Creating Your Own 3D Relief Designs

Aspire is Vectric's high-end design and CNC software. It includes the 2D and toolpath features found in VCarve, then adds the ability to create, combine, sculpt and edit 3D relief models.

This is an important distinction. You do not need Aspire just to cut an STL file that someone else created. VCarve, Easel Pro, Carveco Maker, Carbide Create Pro and MeshCAM can all generate toolpaths from imported 3D files.

Aspire makes sense when you want to create original relief artwork, modify individual 3D components, sculpt details or build more complicated 3D compositions inside the same software you use for machining.

The downside is the price. Aspire is professional software, and its cost can be difficult to justify if you only want to import existing STL files and carve them. It also has a deeper learning curve because it can do so much more.

Aspire Pros

• Full 3D relief creation and sculpting tools
• Combines design, editing, toolpaths and simulation
• Can import and modify external 3D artwork
• Built for decorative CNC router work
• One-time license rather than a required monthly subscription

Aspire Cons

• Expensive
• More software than many hobby users need
• Takes time to learn
• Requires separate control software to run most machines

Aspire is probably overkill if you only want to buy a Form Arcade STL file and carve it. It becomes much more valuable if you want to create the actual 3D relief files yourself.

Carveco Maker and Maker Plus: Strong Tools for Artistic CNC Work

Carveco is based on the same general software family as the old ArtCAM products. It is designed around signs, decorative carving, engraving and 3D relief work rather than mechanical engineering.

Even the entry-level Carveco Maker can import STL models, position and scale them, turn full 3D models into reliefs and create machining toolpaths. It also has vector drawing, V-carving and relief tools. Maker Plus adds more advanced production, design and toolpath features.

Carveco is powerful, but the interface can feel overwhelming when you first open it. There are a lot of tools, menus and concepts to learn. Someone who enjoys having detailed control may love it. Someone who wants to import a file and start cutting five minutes later may find Easel or MeshCAM easier.

Carveco is also primarily subscription-based at the Maker level, although higher editions and plans may offer different license options. It is Windows software, and it does not include the controller that sends G-code to your CNC.

Carveco Pros

• Built specifically for decorative CNC and relief work
• Imports STL and other 3D formats
• Strong relief editing and positioning tools
• Good V-carving, engraving and artistic design features
• More creative flexibility than simple CAM software

Carveco Cons

• Steeper learning curve than Easel
• The interface can feel crowded to a beginner
• Subscription cost for Maker plans
• Windows only
• Requires separate G-code sender or controller software

Carveco is worth considering if 3D relief carving is a major part of what you want to do and you want more design control than Easel provides.

Carbide Create and Carbide Create Pro: A Good Fit for Shapeoko Owners

Carbide Create Core is the free design and CAM software included with Carbide 3D machines such as the Shapeoko and Nomad. It handles common 2D and 2.5D work including vectors, text, pockets, contours, engraving and V-carving.

Carbide Create Pro adds 3D modeling, 3D toolpaths, STL import, rest machining, ramping, tiling and the ability to save standard G-code for CNC machines outside the Carbide 3D ecosystem.

The program is easier to approach than Fusion and less expensive than some professional packages. It is especially convenient if you already own a Carbide 3D machine because Carbide Create works directly with Carbide Motion, the company's machine-control software.

For a non-Carbide CNC, you will generally need Create Pro to export standard G-code, so the free Core edition is not automatically a free solution for every router.

Carbide Create Pros

• Core is included with Carbide 3D machines
• Relatively easy interface
• Pro can import STL files and create 3D toolpaths
• Good integration with Shapeoko, Nomad and Carbide Motion
• Pro offers both annual and perpetual license options

Carbide Create Cons

• Core is focused on Carbide 3D machines
• STL import and advanced 3D work require Pro
• Less powerful for custom artistic relief design than Aspire or Carveco
• Non-Carbide machines require more setup and the correct G-code workflow

This is an easy program to recommend to a Shapeoko owner. For everyone else, it is still worth testing, but compare the Pro cost and workflow with Easel, VCarve and MeshCAM first.

Fusion: Extremely Powerful, but Not the Easiest Place to Start

Autodesk Fusion combines professional CAD and CAM in one program. It is excellent for designing precise parts, furniture components, brackets, fixtures, joinery, molds and other projects where exact dimensions matter.

Fusion can generate 2D and 3-axis CNC toolpaths, and it gives experienced users a huge amount of control. It is also one of the most complicated options in this guide. The interface and workflow make sense once you learn them, but it can feel like an airplane cockpit when your only goal is to carve a decorative STL into a board.

Fusion offers a limited Personal Use license for qualifying non-commercial hobbyists. That word matters: non-commercial. If you are using Fusion to make products for a business or to sell what you create, you need to make sure you are using a license that allows commercial work.

Fusion Pros

• Professional CAD and CAM in one program
• Excellent for precise and mechanical parts
• Powerful 2D and 3-axis machining tools
• Detailed tool libraries, simulation and toolpath control
• Limited free Personal Use option for qualifying non-commercial users

Fusion Cons

• One of the steepest learning curves on this list
• Overkill for many basic signs and relief carvings
• Free Personal Use licensing is non-commercial and feature-limited
• Requires separate software or machine control to send G-code
• Cloud-connected workflow and Autodesk's licensing model are not for everyone

Fusion is a great program when you need the CAD power. It is not what I would recommend to someone who just bought their first CNC and wants the quickest way to cut SVGs or relief STL files.

MeshCAM: A Simple Way to Turn an STL Into G-Code

MeshCAM is different from most of the other programs in this guide because it focuses on doing one job: taking a 3D file and creating CNC toolpaths without forcing you to become a CAM expert.

You load an STL or another supported file, choose your cutters and quality settings, and let the software calculate the roughing and finishing toolpaths. Advanced settings are available, but the basic workflow is intentionally simple.

MeshCAM runs on Windows and Mac, uses a one-time purchase instead of a subscription and supports standard G-code machines through its post-processors. It is a strong option for someone who already has finished STL files and does not need a large set of design tools.

The tradeoff is that MeshCAM is not a full design program. If you need to create signs, edit vectors, add text or build complex layouts, you will probably use another program first. You will also need separate control software to send the G-code to your CNC.

MeshCAM Pros

• Very straightforward STL-to-G-code workflow
• Designed for people who are not CAM experts
• Useful roughing and 3D finishing strategies
• Runs on Windows and Mac
• One-time purchase with no required subscription
• Works with many standard G-code CNC machines

MeshCAM Cons

• Limited design and vector-editing tools
• Requires separate control software
• Less of an all-in-one workflow than Easel
• The interface is functional but not as modern as some alternatives

MeshCAM makes the most sense when you already have the design and just want a relatively painless way to machine it.

CNC Software Comparison

Software features, pricing and license terms can change, so always check the current version before purchasing a plan or license.

What Software Do I Need to Cut a 3D Relief STL File?

If you download a 3D relief STL file, you need CAM software that can import the STL and create 3D roughing and finishing toolpaths. Importing the file is only the first step.

At a minimum, the software should let you:

• Set the exact material width, height and thickness
• Scale the STL without distorting it
• Position the model within the material
• Set the maximum carving depth
• Create a roughing pass with a larger bit
• Create a finishing pass with a ball-nose or tapered ball-nose bit
• Control stepover, feed rate, plunge rate and depth per pass
• Preview or simulate the finished toolpath
• Export G-code using the correct post-processor for your machine

Easel Pro is one of the easiest ways to do this. VCarve, Carveco, Carbide Create Pro and MeshCAM provide more options depending on the level of control you want. Fusion can do advanced 3D machining, but it is not the most beginner-friendly way to cut decorative relief art.

The quality of the STL matters too. No CAM program can magically turn a bad 3D model into a clean carving. Start with a relief file that was designed with CNC machining in mind, then use a realistic bit size and finishing stepover for the amount of detail you want.

Do Not Forget the File License

Software permission and design permission are two separate things. Paying for commercial CNC software does not automatically give you the right to sell products made from every design you import.

Always check the license that comes with the SVG or STL file. Some files are personal-use only, even if you paid to download them.

Every Form Arcade CNC relief STL file includes commercial-use rights for the finished physical products you make. That includes the free files. You can use compatible CNC software to create the toolpaths, carve the design and sell the finished piece. The digital file itself cannot be resold, shared or redistributed.

So, Which CNC Software Should You Choose?

Start with the easiest program that can reliably make the projects you care about.

If you are brand new and want the least frustrating path from design to finished cut, I would start with Easel. The subscription is annoying when you need Pro features, but the software is genuinely easy to use.

If you use your router constantly, want more control and would rather buy software once, VCarve is probably the strongest overall upgrade. Choose Desktop for a smaller machine and Pro for a larger work area or production features.

If you want to create your own detailed relief models, look at Aspire or Carveco. If you make mechanical parts and need exact CAD tools, learn Fusion. If you already have finished STL files and only need a simple way to create G-code, try MeshCAM. If you own a Shapeoko, start with Carbide Create before buying something else.

Most of these programs offer a free version or trial. Download two or three, import the same real project and see which workflow makes sense to you. A feature list can tell you what software is capable of doing. It cannot tell you which program will make you want to throw your laptop across the shop.

Frequently Asked Questions

What is the easiest CNC software for beginners?

Easel is one of the easiest CNC programs for beginners because it combines basic design tools, automatic toolpath creation, simulation and machine control in one interface. The downside is that advanced features such as V-carving and 3D STL carving require Easel Pro.

What software can open an STL file for CNC carving?

Easel Pro, VCarve Desktop, VCarve Pro, Aspire, Carveco Maker, Carbide Create Pro, Fusion and MeshCAM can all work with 3D files in some form. For decorative CNC relief STL files, Easel Pro, VCarve, Carveco and MeshCAM are among the most direct choices.

Do I need both CAD and CAM software for a CNC router?

You need both CAD and CAM functions, but they do not have to be separate programs. Easel, VCarve, Aspire, Carveco, Carbide Create and Fusion combine design and CAM tools. If you buy a finished STL or SVG file, you may only need CAM software to create the toolpaths.

Can I use free CNC software to make products I sell?

That depends on the software license. Some free programs are open-source and allow commercial use, while other free licenses are limited to personal or non-commercial projects. Fusion's Personal Use license, for example, is intended for qualifying non-commercial hobbyists. Always check the current software license before using it for a business.

Is Easel free for CNC?

Easel has free and paid plans. The free plan can handle basic design and carving, but it limits how often you can carve or export G-code. Features including 3D carving, V-carving and unlimited carves are part of Easel Pro.

Can Easel carve Form Arcade STL files?

Yes. Easel Pro can import Form Arcade's relief-style STL files and create the roughing and finishing toolpaths needed to carve them on a compatible three-axis CNC router.
