For example, this is helpful if you want to confirm the Z = 0 location relative to the tool paths. The plot area image can be manipulated by using the view cube in the top right section of the plot area. This is very helpful if you are not exactly sure where to set the origin when setting up your part on the machine. The X, Y, Z = 0 location is represented by the intersection of the red green and blue lines. The following list of tips will help you get the most out of looking at your g code in NC Viewer.
User Tip – If you do not see a tool path, try zooming out or panning around the screen. To step through the G Code line by line, click a line of G Code in the G Code window and us the up and down arrow keys. You can also step through the code line by line. Step 3 – Click the “Plot” button in the G Code window Step 4 – Click the “Play” button in the plot area to see a simulation of your g code. You can either use the file menu in the top left portion of the window or copy and past your g code into the g code window on the left. Step 2 – Load you G Code into the program. Main Features of NC Viewer Step 1 – Click the link to navigate to NC Viewer. The main screen of NC Viewer is annotated in the image below with the key functions of the tool. The following is specific to NC Viewer but the process will be similar for other simulators.

No need to download or install a program. This runs directly in your browser window. Ok, so I want to use a g code simulator, where do I get one? My favorite is called NC Viewer a free browser based tool. nc file just as your CNC machine would and creates a graphical representation of the tool paths and movements of the machine.

What is a G Code SimulatorĪ g code simulator or g code viewer is a software tool that lets you test g code you created. I could test the g code without risking my machine or walking downstairs into the garage. This was a perfect case for a g code simulator. I didn’t trust the g code the programs were generating. That is, programs the generate g code to engrave text. I started using a g code simulator when I was experimenting with engraving programs.
This is where a g code simulator can really help. What if something doesn’t work they way you expect and you need to modify the g code. How do you know if it will work? You could take it to your machine and set your x, y & z origin (0,0,0) location safely away from the work table and then run the program. Say you have a g code program that you just created or downloaded. However, as I learned more about CNC machining, I found myself using a g code simulator to save time. I’m a hobby machinist, why do I need a g code simulator? I asked the same question for a long time.
