Moving to an Absolute Position

Absolute moves are measured in real world units (e.g. millimetres), relative to the
Home position.

1) Click the position display.

Fig. 4.3   Absolute Position Popup Window

2) Enter 3.0 into the pop up window

3) Click ‘OK’. Notice that the position display counts up to 3.000 to indicate a move

to the absolute position 3.00mm.
