Sub-program information:
Overview
Program repetitive sequences or patterns in a sub-program. Enter
sub-programs in the program after the end of the main program. Call
sub-programs from the main program.
 A sub-program can use any code or move type. For example, to cut
a contour twice (one rough pass and one finish pass), program it as
a sub-program. You can call the sub-program from the main program
as many times as required, but you enter the parameters only once.
 sub-program(s) must be stored in the same file as the main program
that calls them.
 You can store sub-programs anywhere in the program after the main
program. They do not have to be entered in numerical order or begin
on any specific block number.
 It is possible to nest Calls to sub-programs within other
sub-programs, not just from the main program.
 Loop (repeat) sub-programs moving along any axis in increments
each time the loop runs.
 Rotate, Mirror, and/or Scale sub-programs.
Ending the Main Program
The main program should always be defined in every program with the
EndMain command, although this is absolutely required when using a
sub-program. The EndMain command must come before any
sub-program definitions.
 Select "Sub Programs" and then "EndMain" from the pop-up menu.
 Conversational format: EndMain.
 G-code format: M2.
