The MEASUR soft key is usually used for setting Work Coordinate systems. If you use an edge finder to pick up the left edge of your part, and you want that edge to be G54 X0, just highlight any field (X, Y, or Z) in the G54 offset, then type X-.1 and press [MEASUR]. If G54 is active, the X Absolute position should now read -0.1000 |
