Well, the Mxx idea would work in a single controller easy enough If the
device itself was mechanical. That other brilliant idea using another
computer would only work If there is not consequence when a bit is up or
down at any point in the X and Y..... I guess that is what I don't quite
get. Do you let the X-Y continue on and the Z can lift randomly anywhere
? If it can lift anywhere, at any time, I would just apply the Z motion
externally with a variable speed DC motor like a typical Soindle Sander.
Then at least it is somewhat adjustable to whatever feedrate things are
running at.

If it were control based, I don't think it is that big of a deal
provided a control developer has time to do it. If this is common on
Stone machines you have seen, by all means, Run this past Rick at FC.
Sounds like a simple "ignore" Z axis moves in code, Allow a separate
"setup" file to dictate lift/plunge durations, heights and speeds when
in THAT mode...
