Important: If any axis word from the current plane is designated in the
block, the L-word is ignored and the control calculates the end point from
the angle and the axis word. If an angle (,A) or a length (L) is
programmed in a block that also contains both axis words in the current
plane, then QuickPath Plus is not performed and the control ignores the ,A-
and the L-words in the block.

No Intersection Known
This feature of QuickPath Plus allows the programmer to define two
intersecting, consecutive, linear tool paths without knowing the point
where the actual intersection takes place. Both of these blocks must be
linear blocks and programmed in absolute mode. The angle of both of
these lines must be known.
This is done with a sequence of two linear blocks (in the current plane) in
which QPP is used to calculated the end point of the first block. The start
point of the first block is the current tool position.
Important: The second block of these two blocks must be programmed in
absolute mode. Any attempt to program the second block in incremental
generates an error.
