Each axiscan be zeroed out independently, to then show its position relative to whereyou selected to zero that axis. To zero out a specific axis, press HAND JOG,and then press POSIT. When you Handle Jog the X, Y, or Z axis and then pressORIGIN, the axis that is selected will be zeroed. Or, you can press an X, Y, or Zletter key and then ORIGIN to zero that axis display. You can also press the X, Y,or Z key and enter a number (X2.125), then press ORIGIN to enter the numberin that axis display.MACHINIST’S CNC REFERENCE GUIDE13
