Quick: What’s the Best Free CAD Software out there? How about the Best Free CAM Software?

Download cnc studio for free. System Utilities downloads - CNC Studio USB by GoCNC and many more programs are available for instant and free download. The game that started the C&C series and introduced the world to GDI, Nod, Kane, Tiberium and Mammoth tanks!

We can help! Here’s your guide to the best free CNC software that’s out there. Some of it is ours, some is from 3rd parties.

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.”

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, we might have come out a lot better. And sometimes free has sneaky hidden costs.

Keep all that in mind as you check out our choices for the best Free CNC Software you can find.

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.

So check out our free stuff!

G-Wizard Calculator

We do a terrible job advertising it, but most of G-Wizard Calculator is free. Seriously. You sign up for the free trial, and when that ends, even if you don’t purchase, most of the tabs will go right on working for you. There’s a giant treasure trove of useful calculators, utilities, and reference information there including:

Fancy scientific calculator with automatic unit conversions and much more.
The ultimate productivity hack for busy people–the same ToDo list with Pomodoro timer system I use myself to get all this crazy stuff done for CNCCookbook.
Geometry and Trig Calculators for Right Triangles, Oblique Triangles, Bolt Circles, Dovetails, Tapers, Chamfers, Drilling, Chords, True Position, Points, Turner’s Cubes
Fits and Tolerances for ISO 286, ANSI B4.2, and DIN 7172
Thread Database with all the dimensions, tapping drills, and more
Drill Chart
Fastener Database with dimensions for Socket Head and Flat Head Cap Screws
Weights and Volumes for standard metal structural shapes as well as standard lumber sizes
Thermal Expansi0n Calculator
Electrical Ohms Law Calculator
Resistor Color Codes
CNC Servo and Stepper Motor Sizing Calculators
G- and M-Code Quick Reference
Hardness Quick Reference with Rockwell (A, B, C, D, 15H, 30H, 45N), Brinell (Std, Hultgren, Tungsten), Vickers, and Shore scales
Rigidity Calculator to help figure your tool rigidity
Chatter Calculator to figure the right spindle speed to stop chatter
Geometric, Dimensioning, and Tolerancing Quick Reference

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! ]

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 G-Code Editor? Free G-Code Simulator? Free Conversational CNC?

G-Wizard Editor

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-code faster. Take the free 30-day trial and see for yourself.

Downloader Beware: The software mentioned above this section is our software, so we know it is wholesome and safe to download. Below this line you’ll find free CNC software from others.

Every now and then a great piece of free software will save you time and money. Just be aware it is a big bad world online, and free software or freeware is a tool used from time to time by those up to no good. CNCCookbook isn’t vouching for any of this software and we don’t necessarily use it ourselves. It’s just stuff we’ve come across or had recommended to us by readers. Make sure your antivirus program is tuned in and turned on if you decide to download freeware and start using it. Just sayin’!
