APPENDIX BProgramming Examples in G Code

There are many ways to approach G-code program generation. One way is to solely rely on the output generated from the postprocessor file your CAM program uses. Yet another way is to manually write each line of code yourself–with or without the aid of a G-code programming editor. A third method is to use a combination of the two previous approaches.

I often tend to favor the third method of producing cut files, especially when there are multiples of the same part needing to be done on a sheet of material. There are several advantages behind using this type of a combined approach:

• You are only dealing with one instance of G code for the artwork rather than having multiple instances of the same file to ...
