Path segmentation for path axes

Length of SPP path segment
SPP is used to specify the maximum distance between strokes and thus the maximum
length of the path segments in which the total traversing distance is to be divided. The
command is deactivated with SPOF or SPP=0.
Example:
N10 SON X0 Y0
N20 SPP=2 X10
The total traversing distance of 10 mm will be divided into five path sections each of 2 mm
(SPP=2).
Note
The path segments effected by SPP are always equidistant, i.e. all segments are equal in
length. In other words, the programmed path segment size (SPP setting) is valid only if the
quotient of the total traversing distance and the SPP value is an integer. If this is not the
case, the size of the path segment is reduced internally such as to produce an integer
quotient.
