The information included in this library describes machining codes (G-code, M-code, and more). This information is also included in our mill Operator’s Manual, which you can download from our support site.


The following sections define the languages that are understood and interpreted by PathPilot, and is only intended for reference:

To learn about the principles of the control language (so that you can write programs by hand from first principles, for example), we recommend that you consult an introductory textbook on G-code programming.

To create and edit G-code files, we recommend using a text editor like Gedit or Notepad++. Don’t use a word processor to create or edit G-code files, which leaves unseen codes that may cause problems or prevent a G-code file from working.
