Testing and running | Program run
Example of multi-level block scan
You run a main program with several subprogram calls in the
NC program Sub.h. You work with a touch probe cycle in the main
program. You use the result of the touch probe cycle later for
positioning.
After an internal stop you wish to start up in NC block 8 in the
second call of the subprogram. This subprogram call is in NC block
53 of the main program. The touch probe cycle is in NC block 28 of
the main program (i.e., before the desired start-up point).
