There is a parameter that controls the absolute position display at 'reset'. I think its at 1201.
Then there are parameters to control relative positions at 3104. I think he may be hitting reset at some point of picking up tool lengths and the display changes position and its relativity. If he zeros out his relative Z (when the machine is at machine position "0") it should stay. If he hits reset and the Z changes, then either stay off the reset button (and maybe MDI) or change the parameter (3104 bit 3 I think controls the relative and absolute values for each other). Do you have a book?
