Just helps with accuray, doing it by hand and eyeballing the dials it can be easy to off track by a thousandths, espicially with backlash or slop if you do not account for it, backlash is the amount you turn before the feed engages, so say if your machine has 5 thousandths of a back lash and you zero out your machine and you need to make a 20 thousandth cut, if you don't account for the 5 backlash and do your cut at 20, your actual cut is 15, you would need to cut to 25 to get the 20 and account for the backlash. A dro takes care of all that, it doesn't start registering until you actually move on the x,y or z axis
