Have you CAMed a part for your machine and the G code still needed some tweaks after? Do you need to add some small lines of initialization code to your G code? Ever wonder how the post processor gets called and executes? Well here is a walkthrough of the various parts in a post processor.
The post processor is needed to output the cam information into a G code file formatted for your machine. We will review all the major functions of the post processor and describe how they interact with the CAM engine. I also describe some of the changes I made to my processor to better suit my machine and situation.
This is a fairly high level walkthrough so if there is anything specific that you would like to see please comment or email me [email protected]
