Programming

Explanation
SPP
Size of path section (maximum distance between strokes); modal
SPN
Number of path sections per block; non-modal
Function
Path segmentation
When punching or nibbling is active, SPP and SPN
cause the total traversing distance programmed for
the path axes to be divided into a number of path
sections of equal length (equidistant path
segmentation). Each path segment corresponds
internally to a block.
Number of strokes
When punching is active, the first stroke is executed
at the end of the first path segment. In contrast, the
first nibbling stroke is executed at the start of the first
path segment.
The number of punching/nibbling strokes over the
total traversing path is thus as follows:
Punching:
Number of strokes = number of path segments
Nibbling:
Number of strokes = number of path segments + 1
Auxiliary functions
Auxiliary functions are executed in the first of the
generated blocks.
