I might point out that max velocity is not in percent.
It is an absolute setting of units per minute (mm per minute in your case)
That does explain why it works strangely to you.
And yes I'm aware that possibly no commercial control works this way.
IIRC it was an easy way to implement overriding of rapids at the time.
Rapid override would be a great addition - I have a patch on the dev list
just not sure it is the best way to go yet.
When upgrading major versions (eg 2.5 to 2.6) one should expect big changes.
We try to outline them in the wiki.
One should be extra careful when upgrading major versions because of these
type of changes and also because they are inherently less tested.
That's the perils of upgrading
(which you don't need to do unless there are new feature you need/want)
If your keen on more input to the development of linuxcnc, might I suggest you
subscribe to the dev list.
