12.5 Smooth the path and the feedrate.
By default, the CNC calculates the space and the feedrate on the main three axes and the
rest of the axes follow their corresponding feedrate. This way, on a machine that moves more
than tree axes and has the kinematics and RTCP active, the tool tip moves at the
programmed feedrate. However, when these machining operations show discontinued
movements on the main axes, this process can generate irregularities on the velocity profile
and, therefore, the resulting movement might not always be continuous.
To solve both situations, the CNC offers several instructions that make the movement a lot
more continuous, thus improving part finish quality and reduce machining time considerably.
These instructions are incompatible with each other.
12.5.1 Smooth the path (#PATHND).
This instruction being active (#PATHND ON), the CNC calculates the space between all the
axes and obtains a smoother movement. If this instruction is not active (#PATHND OFF),
the CNC calculates the space on the three main axes.
In either case, the CNC applies the programmed feedrate to the three main axes; the rest
of the axes move at their corresponding feedrate to end the movement of them all at the same
time.

Properties of the function and Influence of the reset, turning the
CNC off and of the M30 function.
Instructions #PATHND and #FEEDND are incompatible with each other. On power-up, after
an M02 or M30 and after an emergency or a reset, the CNC assumes the behavior set by
the machine manufacturer (parameter FEEDND].
