Absolute vs Relative G-Code Coordinates
I just added a chapter on Absolute versus Relative G-Code Coordinates to our G-Code Tutorial.
You might not realize it, but you already have a pretty good intuitive grasp of how absolute versus relative coordinates work. Suppose you’re in a grocery store and you ask the clerk which aisle the cookies are on. If he responds, “Go to Aisle 14 for the cookies,” that’s an absolute coordinate that is relative to the first aisle–the grocery store’s “part zero”. If instead he responds, “It’s three aisles down that way,” that’s a relative coordinate. We’re used to both kinds in everyday life and both are useful depending on the situation. Read the chapter to see how this all works when writing your part programs.
