Each given layer contains a set of contours, which bounds the material regions from the nonmaterial
regions of the layer.
Each contour itself consists of one outer boundary and a number of inner boundaries, which
describe holes inside the material area of the outer boundary.
Each boundary consists of a number of line segments, which are connected to a closed poly-line.
For each of these line segments, a G-Code command line is written to the file, which gives the
NC control the coordinates needed to move the x- and y-axis from the actual position to the
start position of the next line segment.
HINT: If a spot compensation is applied (by calculating hatches or supports), these modified
boundaries are written to the file. Otherwise the original boundaries are written to the file, which
could result in a deviation of the part geometry due to the tool or beam radius deviation.
Contour start:
Here you can specify any command lines to initialize the generation of a new contour.
HINT: Depending on the NC control and the NC device you could for example tell the control to
change the tool, the material or anything else that is needed.
Contour segment:
Here you can specify the command line for a single contour line segment. This simply tells the
control how to move from the start coordinates of the actual segment to the start coordinates of
the next segment by using G01 and macros as placeholders for the coordinates ([NEXT_X],
[NEXT_Y], ..).
You should also consider to specify a feed rate value here using the macro [FEED_CONTOUR] or
[FEED_CONTOUR_OPT].
HINT: In addition to the movement itself you can specify additional parameters for the line
segments, e.g. a spindle speed (S-command).
Example:
Profile: N[CL_NR] G01 [NEXT_X] [NEXT_Y] [FEED_CONTOUR_OPT] S1
