That is a very interesting question Gene... I have no idea. The standard screw comp works in both direction so it takes into account backlash compensation. But you want to correlate the lathe X compensation with the Z movement to comp for bed wear/error. . I'm going to try the standard screw comp out next week on a brand new ball screw that must have been made with a hammer, anvil and file. The screw it out something like 0.030 over 12 inches in one spot. This is a new screw supplied by Flow for a Flow water jet. I can't believe they sell this junk. After the screws were purchased Flow said that they screw map each screw with a laser... and now I know why!
