The way M6 is processed (with Les Newell's fix) would be ideal if it
could be integrated somehow into the pause behaviour.
I guess that Stop, Pause and M6 all have the

Reminds me - must be able to toggle spindle off/on during pause.

the tool where it wont hit anything on the way back. I don't think
that's unreasonable. Some in the "nanny state" seem to think that is,

oor. I've been able to up my feeds by 20%

Only drawback is it doesn't do re zero during a pause, yet. I can live
with that, for now. But - as I said in my original post, it's only

It's highly desirable for jog while paused too. Never broke an insert
