In joystick mode the stage Z scrollbar thumb button is centrally positioned and
may be dragged up or down to move the Z ttavel. Again the further from the
centre the faster the movement, and movement is stopped when the button is
released. The scroll bar increment and decrement functions give a single shot
magnification related movement.
Joystick mode may be used before the stage is initialised (i.e. when it's true
position is entered) and in this case the position indication may be erroneous.
Goto Mode
The stage may only be selected to GOTO mode when it has been initialised (i.e.
when it's true position has been defined). In this nK)(Je the window represents the
XY co-ordinate space of the stage and it's current position is indicated by a RED
dot The mouse may be used to select a point within this space to defme the
absolute stage position required. A BLUE dot is used to indicate the required
position. When the required position is requested the stage will move to it. If a
stage request is made while the stage is already in motion then the current motion
will be aborted.
The stage Z scroll bar in GOTO mode indicates die cun-ent Z position by the
thumb button, this may be dragged to a desired ABSOLUTE position or the
coarse/fine scroll bar functions used to adjust the position of Z.

on/off to indicate that backlash correction should be perfonned when in Goto
mode. and an Execute Backlash command which initiates a backlash correction
