You have a MX2500 st ? And if i read you right , your looking to save the tool offsets with/when down loading the program? (or just output to card). Do you use the toolsetter with the b axis at zero when setting tools .
I know the mx machines iv used the tools didnt leave the machines so uploading the offset wasnt done. New part ment new jaws, rest g54/g55 and the passoff point for the sub spindle, and run the parts.Any time the top axis had to be moved I used the M400 and all the offsets were recalculated. Way sweet.If your not useing the M400 have your dealer show you how it works
Do you have a lower lathe turret on your machine?
