Skip blocks are skipped during machining.
When executing a jobshop program, it is converted into a G-code program.
In the program, the measurement results screen display is activated while machining.
Program processing stops at the points you defined as relevant to stop before the program
started. These may be, for example, especially critical points, at which you can check the
correctness of the sequence or exclude collisions.
You can specify NC functions (auxiliary functions, subprograms) and NC function transitions as
being stop-relevant.
As standard, the following conditions can be selected as relevant to stop in the "Program con‐
