## What Software Do Beginners Need?
Here’s the lowdown for anyone who is a CNC Beginner. There are many kinds of software for cnc, but the minimum software you will need includes:
- CNC Control Software. This is the software that actually runs your CNC Machine. If you bought a machine assembled or as a kit, it may very well come with CNC Controller software. If not, the CNC Controller software we list below is excellent, especially for CNC Routers

- CAD Software. CAD Software is what you’ll use to create drawings or 3D models of the parts you want to make. Plenty of good choices down below

- CAM Programs. After creating a drawing or 3D Model, the next step in the CNC workflow is to use the CAD software file to generate g-code using CAM Software. BTW, if you want to learn more about g codes, check out our free course

- Feeds and Speeds Calculator: CNC’ers tell us that Feeds and Speeds is one of the hardest parts of CNC to learn. We can make it simple using our G-Wizard Feeds and Speeds Calculator and cut out a big piece of your learning curve

The Control Software is self-explanatory, but the other three programs are what’s needed to produce the g-code files that control your CNC Machine’s motions. For more on how these various packages work, check our CNC Router Software article. It’s a good introduction

## Is “Free” The Right Choice?
This may seem an odd way to get started, but I need to ask the question in all seriousness. You may have heard the expression, “There ain’t no such thing as a free lunch.”
You’ll be spending more hours in front of your CAD and CAM Software than you will in front of your CNC Machine, so choose it carefully

Sometimes free is totally awesome and there are no strings attached. Other times free makes us choose vastly inferior solutions. We spend so much time fighting with the free software that in the end, had we spent just a little bit on paid software, we might have come out a lot better. And sometimes free has sneaky hidden costs


Remember these packages take time to learn. Your time investment learning the software is lost if you make a bad choice and wind up switching packages

For those reasons, we include a section of “Almost Free” software that we think might be better than the free software. At least check out these packages so you’ll know for yourself

Keep all that in mind as you check out our choices for the best Free CNC Software you can find. And keep in mind risk versus return. CNC Hobbyists aren’t risking a lot except their time. Small business users are risking their income and perhaps even their business if they make a wrong choice

## CNCCookbook Free CNC Software
We always provide a free trial for our software. In addition, when we’re introducing new products, we release them for free while in Beta test and don’t charge until we finish the software. Typically you use it for many months if not a year or two when that happens. We don’t believe in shipping software until it is great. In addition to all that, some of our software is filled with a ton of free features even if you never subscribe

Phew! I can hardly keep up with all of it myself. I know there a lifetime subscribers who are still delighted at the new things they discover. And we just keep adding more all the time!
I thought I’d make a quick video showing how it all works:
All of this will save you time digging through machinery’s handbook or trying to Google for it. It’s all stuff that I use constantly and you will love having it at your fingertips. So what are you waiting for–give the G-Wizard free Trial a try:
## [ I Savvy, Get Me My Free Trial Now! ]
Something else to know is that G-Wizard Calculator has special features not just for CNC Mills and CNC Lathes, but also for CNC Routers. If you have a CNC Router, you’ll love the following:
- Support for hundreds of wood species and plastics. These are the materials most CNC Routers cut the most often, and many other Feeds and Speeds Calculators don’t cover them at all

- Tool Deflection and Machine Rigidity Calculations take into account the special needs of CNC Routers

- Our exclusive Vacuum Pop-Off Calculator will limit cutting forces on small parts so they stay down on your vacuum table

- And much more…
BTW, you have the choice of buying the software outright (lifetime subscription) or subscribing. Now I hear all the time from hobbyists who don’t think they can afford G-Wizard. First thing is that one year is cheap–not much more than a single cutter costs. But okay, let’s suppose you still think that’s too expensive. The thing is,
*at the end of that 1 year,* *Feeds and Speeds keep right on working too*

What’s the catch?
The catch is that once the subscription expires, there’s a spindle power limit equal to 2 horsepower for each year you subscribe. This is perfect for a hobbyist. A small CNC Router may not be able to use more than a 2 horsepower cut–tiny machines just aren’t rigid enough. That means a lifetime of Feeds and Speeds, limited to 2 HP, for just the cost of 1 year of subscription. It’s perfect for the hobbyist trying to save

It gets better too. The 3 year subscription has a 5 Horsepower limit when the subscription expires. Now come on, hobbyists. 5 HP for life? If you have a bigger machine than that you don’t need free


And, if you ever get a more powerful machine, just re-subscribe to unlock the limit. No muss, no fuss

 I want a FREE Feeds and Speeds Calculator
OK, I hear you. At least try the G-Wizard free trial because you’ll get top drawer feeds and speeds free for 30-days. When that’s done, if you’re still looking for free, we’ve got your back:
 [ FREE Feeds and Speeds Calculators ]
## Free G-Code Editor? Free G-Code Simulator? Free Conversational CNC?
 G-Wizard Editor
**G-Wizard G-Code Editor and Simulator**
Everybody who tries G-Wizard Editor loves it because it’s the first G-Code software whose focus is on simplifying g-code, and it’s also the first to build in Conversational CNC. With conversational CNC, you can work without using CAD. Just answer a few simple questions and GW Editor will write the g-code for you. It’s for all those jobs you were thinking would be faster on a manual machine, and it’s a totally free additional module you get with G-Wizard Editor

As far as simplifying g-code, GW Editor is the shizzle for that too. It tells you what each line of g-code does in
*Simple English* in a little hint window. Seriously! Tons of schools are using it because it works to help students understand g codes faster. Take the free 30-day trial and see for yourself

## More Free CNC Software
## Best Free CAD Software
CAD Software (Computer Aided Design) is used to create drawings or 3D models of the parts you’ll be making. There is CAD Software for CNC and CAD Software for other purposes like architecture. You want the CAD Software for drawing a CNC design. Avoid the temptation to choose drawing programs like Adobe Illustrator or Inkscape. You want a CAD program, not a drawing program

In addition to finding the package that has a user interface that is the most intuitive to you, there are some other things to be on the lookout for:
- File Types: You want a program that can handle dxf files and stl files. DXF is a 2D file format that’s great for cutting outlines. CNC Routers and Plasma Cutters will thrive on it. STL is a 3D file type. There are more modern file formats–those two are pretty generic. But they’re what you’ll see most often in this class of software

- Personal Use: A lot of the free packages are only free for personal use. They’re not suitable for businesses

- CNC Routers need more artistic features as you’ll be making signs and other decorative items for the most part. Milling Machine users need more functions aimed at precision. That probably means more functions in general–think something like Fusion 360 instead of the simpler programs when choosing your best cnc software

- A lot of free software is Cloud Based. There are pros and cons to it, but I wouldn’t shy away just because the software is cloud based

My favorites on that list are Carbide Create, because it is simple and clean, and Fusion 360, because it is powerful and cheap. Our CNC With Jaime video course for CNC Beginners will start out using Carbide Create

## Free CAM Software
CAM Software takes a CAD drawing from your CAD software and converts it to g-code files that your CNC machine can run. Free cam software won’t have as many kinds of tool paths or other advanced features as paid, but it should be enough to do most simpler jobs. In some cases, like Fusion 360, it can do quite sophisticated jobs too


Note that some software does both the CAD and CAM functions. It’s typically called “CAD CAM Software”. It can be advantageous to combine the functions to create a more consistent user interface. The very simplest CAM programs only do 2D work. That’s fine for something like a plasma cutter and even for many cnc router jobs. But someday, you may want 3D tool path capabilities

I need to burst another bubble here. Many beginners want to skip CAD altogether and convert images to g-code. Some CAM programs can do an image trace, but you’re going to find this is very restrictive and you’ll outgrow it in a hurry. Sorry, but you’re better off learning CAD from the get go

## Free CNC Control Software
Control Software is what takes the g-code and converts it to control signals to operate the motors and other components of your CNC Machine. Think of it as the CNC Machine’s

There are only 3 good choices for free Control Software to use with your CNC Machine:
|GRBL||Free CNC Control Software. Can run on a Raspberry Pihttpsgithub.com/gnea/grbl|
|
|LinuxCNC / EMC2 |Free CNC Control Software||httpswww.linuxcnc.org/|
|
|PlanetCNC Software |Software is free, but you have to buy their controller hardware, so is it really freehttpsplanet-cnc.com/software/|
Try to avoid software that relies too heavily on parallel ports. Fewer and fewer PC’s are available with a parallel port these days

## Free Laser Cutter Software
Note: I’m not delving into this space yet. Laser Cutters are specialized beasts and I want to wait until I have more experience with them and their software before commenting

## Free 3D Printing Software
Note: I’m not delving into this space yet. It’s once again specialized

## Almost Free CNC Software
As I said way up above, you’ll spend more hours in front of your CAD and CAM Software than you will in front of your CNC machine. It might just be worth your time, considering how many hours you’ll spend, to investigate inexpensive CNC Software that may actually be much more productive than free software. It’s hard to underestimate how much having the right CAD and CAM software can improve your CNC satisfaction and success!
Here are some packages I recommend you evaluate because they offer more than most of the free software but they’re not that expensive:
 MeshCam: The world’s easiest CAM Software
When beginners first hear about CAM Software, they assume it is almost completely automatic:
- Load a CAD model into it

- Push a Button

- Output g-code that’s ready to cut

Unfortunately, nothing could be further from the truth for most CAM programs. You’ll spend hours showing it exactly how to machine your part, almost as if it doesn’t really understand much about machining

I dubbed MeshCam the world’s easiest CAM Software after trying it the first time. It literally comes closest to that 3-step ideal beginners expect than any of the other CAM programs I’ve tried. Will it be the last CAM you ever need?
No, you will eventually outgrow it. But you can go very far indeed before doing so. If you just want to get making parts FAST, MeshCam will greatly accelerate your progress compared to something like Fusion 360

More good news (and a full disclosure): I liked the software so much when I came across it that I begged GRZSoftware to let me resell it. So now you can buy directly from CNCCookbook:
Show Me Your MeshCAM Offerings
 Fusion 360, Paid Edition
Fusion 360 can be had for free, but if you plan to make money with it, you’ll eventually have to pay. It has a STEEP learning curve up front, but I want you to know it can carry you for the long haul because it’s CAD and CAM Programs are full-featured. I just want you to consider that it might be worth getting one of the cheaper paid subscriptions up front

Having wiped out a lot of competition with their initial Free market entry, Autodesk are now engaged in ratcheting up pricing to make actual money for shareholders. It’s an old and somewhat nasty game competitors play, but it is here to stay


The free version of F360 does some pretty annoying things, like not supporting tool changing and not running rapids for fast moves. These are artificial limitations that make your CNC work slower and more inconvenient. Even the cheapest paid version eliminates these speed blocks

 Rhino3D: My favorite CAD Software
Everyone is different when it comes to which CAD or CAM will be easiest and most intuitive for them. That’s why I encourage you to try 3, and try them seriously. They’re all very hard to learn so it takes time to try 3. But it will be worth it

My favorite is Rhino3D. I found out through spending time with a lot of packages, that Rhino3D makes me more productive than the other packages. I can bang out CAD models much faster with it, even compared to much more expensive software like Solidworks. I’d encourage you to give it a try

 G-Wizard Calculator: “Lite” Versions
In addition to CAD and CAM, you are going to need help with Feeds and Speeds. CNC’ers tell us it is one of the HARDEST things to master:
I respectively recommend our G-Wizard Calculator to cover that base and make feeds and speeds easy. After all, you have so much to learn about CNC, why not knock out your hardest obstacle up front?
And here’s the best part–it’s CHEAP!
Get the 1 year version of G-Wizard. It costs little more than a nice end mill

When the 1 year is over, G-Wizard will become G-Wizard Lite. The ONLY thing that changes is it will have a 2 Horsepower limit on calculations. Most hobbyist CNC Machines are less than that anyway! What a smokin’ deal
