G Codes For Mach3
So you’d like to play with G-Code but don’t have any sample g-code files?
Nov 19, 2013 DXF to TAP and then to MACH3. This is the high resolution video of the older upload.
For starters, be sure to check out our Free G-Code Tutorial. It’s full of examples on a case-by-case basis.
Want completed programs?
No worries, here’s a bunch of examples:
G-Code Examples for Milling Machines

Griffin Relief.ncc: 3D profiling job for a gryphon logo.
HomeSwitchRearPanelEngrave: A control panel for my CNC electronics.
SupportLogo.ncc: CNCCookbook logo for my tooling rack.
G-Code Macro Examples
Warm Up Program: Runs your spindle and axes to warmup the CNC machine.
How do i turn off microsoft office updates on mac. Peck Drilling: Customize your peck cycle with this macro.
G-Code Examples for Each G-Code and M-Code
Our handy g-code reference lists have links to specific g-code examples for each g-code and m-code.

Create your own G-Code Examples with Conversational Programming
With Conversational Programming, it’s easy to create your own g-code examples…
Conversational Programming is a way to create simple g-code programs with CADCAM software. You simply answer questions in a simple Wizard format and it will generate the g-code for the operation. Our G-Wizard Editor Software has a free built-in Conversational Programming Module you can use to generate all sorts of g-code examples.

Do You Have Some Cool G-Code?
We’re always on the lookout for cool g-code files to add to this page. If you have some you think is worthy, we’re interested. If we wind up adding it to this page for download, we’ll give you a free lifetime copy of our G-Wizard Editor.
Here’s the sort of thing we’re looking for:
- Quick fun projects someone could CNC in a weekend.
- Useful g-code utilities such as subprograms others may want to include in their own g-code.
- G-Code that demonstrates some clever technique others can learn from.
If you think you’ve got just the ticket, send me an email via bob@cnccookbook.com. Include your g-code, tell me what sort of control it runs on, what it is, and briefly say why you think it should be added to our g-code page. I’ll let you know quickly whether I’m going to add it and whether you get your free copy of G-Wizard Editor.
Cheers!
