Comment
: Before loading N15, an M70 intermediate block is generated
in which the spindle is stopped, and M70 is output to the PLC.
Comment
; Output of the implicit M70 to the PLC, no intermediate
block.
Comment
; Output of the implicit M70 to the PLC.
Comment
; Output of M70 to the PLC.
; No generation of an implicit M70 because
axis mode already exists.
