Wahoo's Guide To G & M-Codes (RS-274)
This guide is intended to show usage of the standard RS-274, or "Fanuc compatible" NC Codes in their standard usage. However, this guide makes no guarantees that this will describe exactly what will happen on your control. Many machine tool manufacturers modify the motion codes to satisfy their machines requirements or take advantage of the machines unique capabilities.
Wahoo welcomes any additional input or comments on anything you would like to added or see changed in this guide. You can contact Wahoo with your suggestions at wahoo@xmlcreate.com.
