Using a probe I have a program written to probe a tooling ball on a fixture mounted on a 4th axis and I have the values from that probing assigned to system variable #'s so I can do the math calculations to get to the actual fixture zero. What I want to do is take those values from the system variables and apply them to the g5# work offset values so when the machine is turned on daily It knows where it is. This is a setup program and only needs to be run once when the fixture is first set up.
