By the way Scott, I finally figured out there's no space before the axis letter because it still wouldn't work even after fixing the other stuff you pointed out. I took out the spaces & voila!
The wacky way I home my lathe is strictly due to my being self taught from scratch years ago & my method is what got me up & making parts. Home X at zero, set all tool offsets ref'd from there & home Z to the end face of the part with an opto probe. I have no limit switches, just careful setup.
I've made a lot of good parts with it & my neighbor/customer needs some more soon. That's why I was wanting to to get it back to what I'm comfortable with. My almost 70 year old world is gyrating wildly enough already without changing up everything. 
I do want to study the Centroid lathe manual & do a more conventional system later with limit switches & then learn more about machine coord's & work coord's. I'm weak in that area and it's causing me problems.
