Editing Fusion’s default Tormach post processor can be a daunting task – especially for those unfamiliar with how a post processor works or those who are not comfortable with programming. Before we can look at some of the quality-of-life changes we have made to our own post processors, let’s talk about how to edit a post processor.
Using Visual Studio Code to Understand & Modify Post Processors
VS Code is a free code editor published by Microsoft. Autodesk has developed a plugin that works alongside Visual Studio to directly compare your posted program with the post processor that created it, letting you easily find and edit the lines you want to change. It is a game changer modifying posts!
Post Processor Basics
For those unfamiliar with editing posts, we highly recommend also checking out these videos on the basics.
Adding Timestamps to Posted g-code
We are constantly making small tweaks to our manufacturing processes and CAM operations. This can lead to many different (albeit still quite similar) G-code files on the machine. Take a look at this quick and easy trick to add the current timestamp to your posted files so you can always be sure you are using the most recent version.
Custom Tool Change and End-of-Program Locations
Another useful change you can make to your post is to change the position of the machine table both during a tool change and after the program finishes (e.g. to make the parts accessible to the operator for the next setup).
