You will see that circumstantially when you apply your A-axis that the continuation of the increment makes sense and is desirable.For instance if you are 'incrementally' doing a negative a-axis combined with a positive a-axis move,you will certainly be keeping track of where you are and where you've been within the 360 numbers.Otherwise,you'd be traversing some distance in some other axis rather than just rotating the axis in one place and as with the example of say milling a cone,you would calculate how many turns you need as you went in some axis to cut a proper end and cusp of the cone,prior to cutting and included this in your code which could be accomplished with three moves of three axis at once.This number would be greater than 360 and where the continuing display of your degrees past 360 is a desirable knowledge because it is what you would come up with in your calcualtion for the height and cusp versus rotational turns.-Keith
