Hi Fabric8r,
Yes, XP and XR are similar, so the book will not be wasted. From what we have seen of online previews, XR will actually surpass XP considerably, in ease of use. This in itself will make OneCNC XR easier to pick up, even if you're a typical user who doesn't read the help or do the tutorials. ![Big Grin](images/smilies/biggrin.png)
Many of the new features in XR seem to have been developed based on the user feedback on XP, which showed which areas the users had the most difficulty with. Some issues which XP users struggled with, will never even cross your mind when using XR, because of all the work that has been done in the meantime.
However, last word I heard from the author of the Mastering OneCNC book, was that she would review and write for XR when it is finally ready, too.
However, for newbies in particular to the world of cadcam, I believe the present book to be an invaluable resource to get you off on the right foot. There is no sense in being handicapped by lack of understanding when you own a licence to such cutting edge software.
XR is still in beta testing, but is very close to release. I won't say when, because I don't want to get my hands slapped
First you get good, then you get fast. Then grouchiness sets in.
