Clearly this is a good reason for "Black Box" control techniques. Using
a "proprietary" language (which of course could be shared if the
developer desired to), communicating with external hardware via USB or
even serial port can eliminate some of that. I have heard rumors

Maybe by a "hand cranker".... but, On a CNC mill or Router ?? Now I am
lost..... Even on my simple 3 axis router, I assure you I can and do
have more than one motor turning, and in opposite directions at any
given time, even for simple 2d profiles. How could one cut a 2d arc
where I would need to have negative movement in X and positive movement
in Y, yet having only one direction available ?? I hate to even get into
full 3d continuous motion work where if I do not have the option to run
motors at any direction at anytime.......

Not sure I'd want to give up the ability for turning any motor any
direction I want, at any time.......

I probably missed something. My better half says I never listen very well !

My eyes don't read so good either anymore, not to mention the brain that
is slowing down !

Now this I am a little familiar with as Flashcut had a hard time driving
them. To my knowledge, Marriss and Flashcut have discussed it
thoroughly. As far as I know, FC can run them now. I know FC has added a
few extra driver adjustments in order to get a good "grip" on every
driver one might end up using.

Not being confrontational, Just was trying to get an idea where you
wanted to use that concept. I'm sure there is a use for everything.
