Can tell you 100% It will be a problem from day one if your relying on "feed hold" to stop Instantly because it doesn't. Even with Motion control Card that can process the Code much faster so use lower Lookahead than Mach's PP driver you can't get "feed hold" to stop instantly without losing Steps and that's the whole point of "feed hold" Otherwise you may has well just E-stop and presume lost position.!!
