Let's say tool 1 is a 1/2" end mill and tool 2 is a .250" drill. Since the drill is longer the Z Offset has to be set. I put a .001" feeler gauge on the top of the part. Then I jog the head down and touch the feeler gauge with tool 1 and press Z, ABS/Set to zero it out. Then load tool 2 and go to the jog function and touch this to the feeler gauge. Once that touches the feeler gauge, I can go back to the tool table and under the the Z offset column and press ABS/Set This automatically calculates the difference and sets the Z zero point for that tool.
Do I have this correct?
