on a dual-process lathe, both processes can be in solid-tapping mode at
the same time assuming that they have separate controlling spindles
you must disable CSS before performing solid tapping; an attempt to
execute the tap phase of a solid-tapping cycle with CSS results in a
decode error
cycle stop and feedrate override are acknowledged throughout the cycle,
but can be disabled by G63
you can use active reset to abort the cycle after the cycle stop request
has been acknowledged
to retap a hole, a Q-word must have been programmed when the hole
was originally tapped
block retrace is possible during the tap-in portion of the cycle, but not
during the tap-out
