Description:
This MD is evaluated only if bit0 is set in MD20110 $MC_RESET_MODE_MASK (see
there).
For each entry in MD20154 $MC_EXTERN_GCODE_RESET_VALUES (that is for each G
group), this MD is used to determine whether, on reset/part program end, the
setting in MD20154 $MC_EXTERN_GCODE_RESET_VALUES is used again (MD = 0) or
the current setting is retained (MD = 1).
Example for ISO dialect M:
Here, the basic setting for the 14th G group (settable work offset) is read
from MD20154 $MC_EXTERN_GCODE_RESET_VALUES at each reset / part program end:
MD20154 $MC_EXTERN_GCODE_RESET_VALUES[13]=1 ; the reset value for the 14th G
group
;is G54
MD20156 $MC_EXTERN_GCODE_RESET_MODE[13]=0 ; the basic setting for the 14th G
group
;after reset / part program end
is defined by
;MD20154
$MC_EXTERN_GCODE_RESET_VALUES[13]
;
However, if the current setting for the 14th G group is to be retained beyond
reset / part program end, this results in the following setting:
MD20154 $MC_EXTERN_GCODE_RESET_VALUES[13]=1 ;reset value for the 14th G group
;is G54
MD20156 $MC_EXTERN_GCODE_RESET_MODE[13]=1 ;current setting for the 14th
;G group is retained even after
;reset / part program end
Description: Number of motion blocks across which a spline section is calculated with the
cubic spline (CSPLINE) function.
The larger the value, the closer the generated contour is to the ideal math-
ematical cubic spline, which in the boundary condition CUBIC_SPLINE_BLOCKS =
reaches infinity.
However, the higher the value, the longer the block search calculation time.
