3.3.2-Positioning the 3D Systems Haptic Device

The correct placement of the device will vary from one user to another. You may want to experiment to find a
placement that feels right for you.
• The device should be positioned so that you are comfortable when working with it.
• You should not feel any strain on your wrist or forearm when working with the device.
• If you are left-handed, you may find it easier to work with the haptic device placed to the left of the keyboard.
• Remember to take breaks often to stretch your hands, wrists, and elbows.

Physical Limits of the Device

3.4
The haptic device has six degrees of motion provided by six axis points. All the degrees of motion have physical limits.
When you reach one of these limits you will feel a sudden stop; this is the mechanical stop designed into the device.
Forcing the device past any of these stops risks damaging the device. Take some time to become more familiar with
the physical limits of the haptic device before using the device by moving the device through its full range of motion
at each axis point.
1. First make sure the device is not active; the inkwell should not be lit. If the inkwell is lit, close any haptic applications
you have open.
2. Grasp the stylus as you would a pen, with the free end of the stylus (the eraser end of a pencil) pointing toward you
and the point of the stylus (the end connected to the arm) pointing toward the unit. Using the following illustration
as a guide, gently move the stylus in all directions to feel each mechanical stop. Now, you will perform macro
movements. That is, you will move the device at the "body," "shoulder," and "elbow" of the haptic device.
Encoder articulation: Macro movements. Showing movement of the haptic device arm and the body.
