I use a CAM program to create my GCode files, but I often want to put a note or two at the beginning of the file, or in the file before tool changes. I'd like to put the name of the file, its revision, and what tool and material to use, for example. And on tool changes, I'd like to put the tool name, diameter etc.
How do you do this in GCode so that Mach doesn't read it or trip over it? Is it just a semicolon in front of the comment, like in other programming languages?
Alternately, can I get Mach 3 to display info based on what it reads in GCode? Nah. It would be best to just read the line or two in the GCode header.
Thanks so much for the help.
