Hi Gene. I have had a similar problem to what you are seeing on a mill. It turned out to be an issue with the tool table I was using. Somehow I fat fingered something and ended up with an extra entry in the table unrelated to tool diameter or length offset. Cleared that out and everything started to work again. I had to enable the tool editor to show all of the possible fields, and it became very obvious what was wrong. I think what happened for me was while I was setting tool length I somehow ht an "X" or "y" key just before bringing up the dialog for setting the tool table and the height got stuffed into one of those fields.
I see this as a possible bug with the G43 command bringing into play offsets other than just the tool length. I have become much more deliberate in how I set up the tool table now. Ray --J.

And those traits we detest, sharpness, greed, acquisitiveness, meanness, egotism and self-interest are the traits of success. And while men admire the quality of the first they love the produce of the second. -John Steinbeck, novelist, Nobel laureate (1902-1968) On Sun, Dec 7, 2014 at 6:46 AM, Gene Heskett <ghesk...@wdtv.com> wrote: > Greetings; > > According to the AXIS window title: > > Sim version of AXIS 2.7.0pre0-616-gcd4180d > > I have this board end carving routine almost working. > I can do a right end of y_top motion arc just fine.
