To start execution of a certain program section in a complete
program, place the cursor directly on the required destination block
(using "Search", if necessary).
When you then select a calculation method, consider:
The "External without calculation" method performs a search without
considering the machine functions. That means execution of the
program can only be started a points at which all relevant machine
functions, such as feed, spindle speed, etc. are performed.
For safety reasons, you should therefore choose the "to contour" or
"to end point" method. However, these calculation methods require
more computation time.
