I did a little research on this idea, here's what I came up with:
In the program I could write the following at the start:
#2003=[#2003+#2010] (T03 Line)
#2004=[#2004+#2010] (T04 Line)
#2005=[#2005+#2010] (T05 Line)
Then by adjusting the X value of offset T10, the relative changes would be transfered to each of the three tool offsets at the start of the cycle.
Where #2003 is the X value of the T03 offset and so on. I am not sure if Citizen is using the tool wear offsets or the geometry offsets on its single offset page? If so, those variable numbers may be different.
If anyone has a better implementation, I am all ears...
