G4? Or do you want to put the delay in the machine configuration? On the mazak we connected the spindle VFD's "at-speed" output to EMC's feed-hold input (inverted of course), so the machine won't move until the spindle gets up to speed. I'm not sure thats the right approach, but it worked. Some other things, like tool-change, use a request/reply handshaking model, where one HAL pin tells the external "stuff" to do something, and another pin tells EMC that its done. I suppose we could do something like that for spindle run, and by default loop the request right back to the response so the existing behavior doesn't change. Then you could add a delay or other interlock if you want it.
