I implemented this in trunk. It involved a lot of changes, so it
needs some testing. Any help anyone can give is most appreciated.
Here is the commit message that describes the intended change.
As discussed on emc-developers: wait for the spindle to be "at
speed" (as shown by a hal input to motion) in these cases: before
the first feed move after each spindle start or speed change;
before the start of every chain of spindle-synchronized moves;
and if in CSS mode, at every rapid->feed transition.
John T, can you please add this information to the docs wherever it
describes the inputs to motion or the spindle-to-motion interface?
Chris
