On each axis is a scale that is marked with .2” graduations. These scales are used to establish HOME.
Home is a reference point that can be easily found and repeated. The .2” scales are just an aid to find
thishomepoint.
Establish Home: Explanation
How HOME is established
The HOME location will repeat itself from start-up to start-up within .00005”. So when you start up the
machine from one day to the next it will repeat itself very closely.Thepointisestablishedbythefollowing:
On the end of the servo motor that drives the axis is an encoder that tells the control how far the slide
has traveled. This encoder follows the slide travel incrementally. The encoder does not know exactly
where the slide is, only how far it has traveled.The encoderworksbycountingfinelinesprintedon a disk.
The drawing above is a sketch of this type of rotary encoder. The inside ring of lines is counted to maintain
location. The outside line is used to find a definite location. The encoder will ”see” this line once every
revolutionof the ball screw used to position the slide. TheballscrewusedontheOmniTurnmovestheslide
.2” / revolution. So if we position the slide within .2” of what we want to call HOME and then tell the
control to slowly rotate the screw while looking for the single pulse we can establish this as an easily repeat-
able location. This is how HOME is established.

Jogging with the Joy Stick
The method for moving the slide is to use the ”Joy stick” actuator on the operators panel. Deflecting this
actuatorinthefourdirectionsavailable produces the followingmotions:
Up X axis minus (away from you on attachment; up on GT-75 & Jr)
Down X axis plus (toward you on attachment; down on GT-75 & Jr)
Left Zaxisminus (towardspindle)
Right Z axis plus (away from spindle)
Jog
The purpose of the jog mode is to:
• Establish your ”HOME” position. This is always done after starting up the control.
• Set tool offsets
• Move the slide manually
• Bore soft jaws or collets
To enter the jog mode:
If you are just powering up the control it will automatically take you to the jog screen after the servos are
turned on.
If you are at the main menu as shown below, type ”J” .

To set a floating zero
Depressing ”S” will cause the present position of the axis to become the zero point. This setting of zero
does not effect the location of the Home. This is a local zero that is used in the manual mode if the
operator cares to use it. When this option is used, the control will prompt you to ”PRESS X TO ZERO
X, Z TO ZERO Z”. You can terminate this procedure at any time by pressing the ”ESC” key.
To send the slide HOME
Depressing ”H” will bring up the message ”PRESS X TO HOME X, Z TO HOME Z”. It is suggested to
depress Z first, as this will home Z axis and get the tools back out of the way. Then depress X and the slide
will home in the X axis. This function is used to check that the Home you have set is still where you think it
shouldbe.Neverusethisfunctionuntilyouhave first gone through the ”REFERENCEZERO”procedure
