I have a gear cutting file that I want to nest inside a subroutine. This I have done but for what ever reason Mach3 can't see the "M99" at the end of the program. When you look at the code in the window of the Mach3 at the very end of the GCode M99 is not there but when you open the "Edit G-Code" it is there.
The file was a "Tap" and I changed the extension to "nc" before I added the extra code not sure if that is the problem.
Also I wanted to move the repeat X56mm so I have used G52 to do it not sure if that is the best way.
