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.

Example:
N10 G1 G91 SON X10 Y10
N20 SPP=3.5 X15 Y15
When the total traversing distance is 15 mm and the path segment length 3.5 mm, the quotient
is not an integer value (4.28). In this case, the SPP value is reduced down to the next possible
integer quotient. The result in this example would be a path segment length of 3 mm.
Number of SPN path segments
SPN defines the number of path segments to be generated from the total traversing distance.
The length of the segments is calculated automatically. Since SPN is non-modal, punching or
nibbling must be activated beforehand with PON or SON respectively.
