MAX-VELOCITY global = bad

Ouch!!!

MAX_VELOCITY not being on a per axis basis can be severely limiting. On
my machine X and Y are cable drives and Z is a lead screw drive with a
completely different motor and everything. Z will never be as fast as X
and Y without a complete rebuild... If I were to add the planned rotary
table it may (or may not!) even be as fast as the z axis is now. This
could drag the machine down to a crawl for no good reason. My AHHA
control has individual maximum velocity settings on each axis so it
isn't a problem normally. It just slows down when needed.

In my opinion per axis MAX_VELOCITY settings should be on the very top
of the "What do we want" list! I guess that with a little creativity a
work around could be done. In my case I could set the max_velocity to
the speed limit of the X and Y axes and use a feed rate command whenever
I move Z at maximum rate. It wsould work but what a pain.
