12.2.1 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.

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.
