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. 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.

Try It! Back to Homepage. Hi Denis, thanks for the comment. First let me say, I have never used Aspire. Note, you will not be able to save your creation as a. You will need to click the Save Toolpath button to generate the gcode.
You will want to select a GRBL post processor if available. Otherwise select a generic post processor. It helps me so much and its fantastic, that people like you help others with their knowledge.
I spent hours researching the internet, found your site and followed the instructions. And now I have drawn my first circle on a piece of paper. Heiko, Congratulations! I am thrilled the information was helpful. I appreciate your comment. Enjoy your CNC machine. Feel free to contact me if you have any questions. Very nice article which is best informative.

Parametric programming with macros is something that emerged after the basic standards were in place. Fanuc Macro B is probably the most common standard for it. Many controls are very limited in their capabilities around Macro Programming and there are a lot of detail differences around exactly how Macros work. Many G-Codes need additional information to do their job, so they use other words letters to collect that information. Exactly which words collect which information can vary from one control to the next.
Some controls allow G0 or G Some insist on G Some allow numbers with no decimal, others insist on a decimal or even a trailing zero. If you follow along with our exercises with G-Wizard Editor, you should run a Machine Profile for the Fanuc Controller, preferably by downloading our canned profile.
To learn more about Post Processors, check out our article on them. Look up what g-code dialect your CNC machines use. Are they Fanuc? Or something else? Does the manufacturer claim compatibility with a standard? Here are some common types:. Note: arrows show table motion in positive g-code direction. Handedness is spindle motion and reversed! The cylinders in each drawing represent the spindle of the machine. Be sure to have a look at exactly how the axes are laid out on your machine.
Much more complex configurations are possible when you have more axes. For example, here is a 5-axis setup:. Note that we have added two rotational axes to the basic mill diagram to provide an A-Axis and a B-Axis. Now that we know what the coordinate systems are, how do we express coordinates in G-Code? Spaces between the letter and its value are optional.
For example, a position that is 1 inch from 0 along X, 2 inches along Y, and 3 inches along Z is written as:. You get used to reading them all run together like that quickly, but you can format them with spaces to make them more readable:. The example I just gave used inches, but in actuality the controller can be set to use either metric or Imperial. Try not to change units in the middle of a program, do so at the very beginning and then stay with the same units.
The G-Codes to change units only affect how the machine interprets the numbers. Rotating the 4th axis to the 90 degree position might be done as A90, for example. Sometimes, it is very convenient to refer to Incremental or Relative instead of Absolute coordinates. This is easily done with relative moves:. There are lots of cases where relative moves are handy so the ability to switch back and forth comes up a lot. Sometimes, we refer to relative coordinates with special axis letters.
On some controllers, UVW may be used alongside XYZ to refer to relative coordinates without needing to change back and forth between relative and absolute modes. For now, it is enough to be aware that incremental coordinates exist.
A little later, we have an entire chapter just on the subject of incremental versus absolute coordinates. The last Coordinate System concept I want to cover is that of Offsets.
Offsets are another fancy way to think about relative motions. Each is held in a vise on your table at the same time. How do you make one program that can do both parts without having to change the program for the position of each part? The answer is that we use a Work Offset. More detail on those later, but for now, imagine that Work Offsets let us position the X0 Y0 Z0 origin in more than one place. We can put one on the first vise and another on the second vise.
Now just by changing the work offset the same program can work to make the part on either vise. Most CNC controllers have an offsets screen where you do that. I mention this because any time you get a chance to learn about offsets, take the time to do so.
A plane is a flat 2 dimensional space defined by two axes. For example, the default plane on most mills is XY. If you draw an arc without specifying a change in the plane, it will be drawn on the XY plane.
There is a plane for each combination of the linear axes XYZ:. More on GG19 when we talk more about arcs.
Hey one more thing, just in case you were wondering. Get out the manual for your machine and find the diagram that shows how its coordinate system works. Make sure to leave the manual handy, whether it is paper or online. There are views for Perspective, Top, Front, and Right.
Download the sample engraving file from our download page. Have a look at it in each view. Would you like a handy cheat sheet that tells you everything you need to know to do quick and dirty CNC Tasks? I want to refer you to a special G-Code Cheat Sheet article that goes over all of this in full details and even gives you printable cheat sheet charts you can use. G-Code Cheat Sheet.
We talked a bit about CAM Software already. Our very own G-Wizard Editor is once such program. You could use a Notepad or some similar text editor.
One of the best things about our G-Wizard Editor is it gives you hints in plain English that tell you what each line of g-code does. The hint appears right below the backplot:. For example, lines of g-code are often numbered. What a pain it is to renumber by hand, but the g-code editor can do that for you automatically. Simulators may also be called Debuggers, Backplotters or Viewers.
Their role is the same. You can see the graphical backplot of the toolpath in the G-Wizard Editor screen shot above. You can tell at a glance from a backplot exactly what moves the tool will make when the program is run. A very high quality simulator like the one in our G-Wizard Editor , has a more capabilities than just a backplot:.
If your CAM program includes a true CNC g-code simulator, then yes, it does have a simulated backplot and by all means use it. They just plot the same geometry information that was used to create the g-code output by the postprocessor. This allows for subtle bugs to creep in that are not detectable in the CAM backplot.
