Hmmm.

This may be what you want, but it's a deviation from the RS274NGC spec.
The Txx command is only supposed to prep the next tool. This is useful
on machines with large toolchangers you can issue a tool prep code just
after switching tools, so the carousel will be at the correct slot when
you finish with the current tool. The M6 is what is supposed to
actually change tools. That's when the new offsets are supposed to be
applied (actually, during the first motion after a toolchange). At that
point, if your machine is configured to ask the operator to change tools
(rather than using an ATC), you would have to press cycle start or
whatever to get going again.

M6 is actually supposed to do something :)
