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), followed by the position of the switching point in the object either as
an absolute value via word L or as a relative value via word O. 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*)
