Hey digibbs,
Keep in mind that I've only had my Slant Pro for about a month......
I set up a boring bar block as my initial tool to use for all my setups. I think I numbered it something like tool 99. I used the face to set my zero (using the tool offset page zero, not the zero on the main screen), I then set the edge of my block to set an approximate X value (again, in the offset tab). Once this is done, I run through and add my tools using the offset tab and set everything up.
Now, when I go to chuck up some new stock I throw back in my boring block, type in tool 99 or M6 T9999 in the MDI, jog it over to the face of the stock and hit the zero button on the main screen. From that point on all my other tools are good to go with the new reference.
Just me newbi $0.02 worth.
Later,
Awall
