Best Free CNC Software from CNCCookbook
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 peruse our choices for the best Free CNC Software you can find.
CNCCookbook Free CNC Software
We always provide a 30-day 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 checkout our free stuff!
We do a terrible job advertising it, but most of G-Wizard Calculator is free. Seriously. You sign up for the 30-day 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 30-day Trial a try:
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 1 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 1 horsepower cut–tiny machines just aren’t rigid enough. That means a lifetime of Feeds and Speeds, limited to 1 HP, for just the cost of 1 year of subscription. It’s perfect for the hobbyist trying to save.
And, if you ever get a more powerful machine, just re-subscribe to unlock the limit. No muss, no fuss.
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.
