Oh... one good reason is to allow for safety shutdowns, and also have
everything handled by messages and all the speed, time, actual position
data loggable, and requested toolpaths tweakable and all switches
throwable from the emc screen for debugging and performanc increasing
reasons.  And then another reason to redesign anything is to improve on
what came before by making it all tougher, simpler, more like a hockey
puck.  And then there's price.
