Set the Home Position

This document lists the steps required to adjust the home position of the motion platform using DigiSize. We assume that the user has a good working knowledge of Windows and is very familiar with DigiSize.

Required Tools

In order to complete this procedure, you must have the following:

Procedure

  1. Secure the scan subject (For best results, a Cyberware calibration cylinder should be used) to the motion platform using a few pieces of clay. Try to center the subject over the axis of rotation.
  2. Launch CyDir.
  3. [CyDir]
    CyDir
  4. Press the Scan button. This will open Guee, a program for controlling the scanner.
  5. [Scan Button]
    CyDir - Scan Button
  6. Select the appropriate script, according to your particular Cyberware motion platform, at the top of the Guee window. These scripts (*.ee) are located in the '...\DigiSize\' folder.

  18. Observe the default alignment of the scans. There are two possibilities here:
    1. If there are no obvious gaps in the alignment of the scans, continue to the next step.
    2. If there is some misalignment, complete the following procedure:
      1. Using the scroll bar on the right edge of the CyPie window, scroll to a middle latitude. Basically, you want to see only the middle of the scan subject, not the base or any support features.
      2. Check the Use current lat checkbox.
      3. In the CyPie window, click the Auto Align button.
      4. [CyPie]
        CyPie - Auto Align Button
      5. The scans should now be aligned. At the bottom left of the display section of the CyPie window, you'll see "pos:", followed by a number. This number is the home position adjustment value.
