EMC u can customize up using HAL to pretty much any setup you care for. if thats enough you can wire your own modules to go into hal to do near anything. you can sync two axis/spindles or more while doing a spindle sync move. the list is huge in setups and customizing. EMC is doing things the new fanuc controls and likes are only just getting to grips with if something comes up you wish to do it can always be added its no longer a huge fee cost of a parameter unlock or PLC reload, i find EMC like old Phillips controls what you see is what you get in term of features, if the NC control can do it its there to be used.
before we made the upgrade we did look at new controls, Fagal, Fanuc, Mitsubishi etc but when you start going 5 axis, large program space. then add on new servo drives and motors. a new machine would be the cheaper option in some respect. its all swings and roundabouts in areas. > Forget the fancy math.
