10.3.6 Proximity Point Search
In the memory operation mode, if the proximity point search (DI) is
turned on and the cycle start is carried out, the block in the nearest
position to the current position of the nozzle is searched as described
below, and the nozzle is positioned at the start point of this block and
becomes feed hold state.

(
Xe, Ye, Ze
)

Ls
P (Xp, Yp, Zp)
S (Xs, Ys, Zs)
Point P: Current position of the nozzle (Xp, Yp, and Zp)
Point S: Start point (Xs, Ys, and Zs)
Point E: End point (Xe, Ye, and Ze)
Decision
If the distance Ls between the block start point (Xs, Ys, Zs) and the
current nozzle position (Xp, Yp, Zp) does not exceed the specified
distance L, and the distance Le between the block end point (Xe, Ye,
Ze) and the current nozzle position is longer than Ls, the start point S
is judged to be the proximity point.
