4.1.1 Switching points, H-function
The switching point function (or H-function) provides programmers with a means of using
binary path-specific switches. The number of the switching point must always be specified
first (H<Number>), followed by the position of the switching point in the object either as
an absolute value via word L<Position> or as a relative value via word O<Position>. In the
example below, switching point 2 is being deactivated at position X =40/Y=25 (after the
first quarter of the object).
Example of a relative H-function:
Example of an absolute H-function (the user should know the path length):
N90 G1 X20 Y20
N100 G1 X100 Y40 H-2 00.25

Note!
• Only a limited number of switching point switching actions
(MAX_SWITCHES) can be performed for each path object.
• A switching point position can only be inserted in the CNC text editor! It will
appear as a green dot on the curve in the graphics-based editor.
N1 G1 X100 Y100 H1 O0.5 (*switch on H1 after a half path element*)
N2 G1 X200 Y100 H-1 O0.75 (*switch off H1 after 3/4 of the path element*)
N0 F200 E1000 E-1000
N1 G1 X100 Y100 H1 L75 (*switch on H1 after 75mm*)
N2 G1 X200 Y100 H-1 L50 (*switch off after 50mm*)
N3 G1 X300 Y100 H2 L-50 (*switch on after 50mm after the end of the path element H2*)
