*When programming the first waypoint, it is helpful to start with a “stowed” position which the robot arm can start from. If you are programming a lot of actions it becomes increasingly beneficial to return the arm to this position to iron out errors as you go along. You can also repeat this waypoint in the final step of the program so the arm can return to the initial position; this makes for a more seamless loop when the program repeats.
+

*It is best to verify and troubleshoot each set of movements as they are completed. If you wait until you have a whole string of movements before checking the program you may run into complications which will be much more difficult to fix.

LMI Technologies HDI 100 3D scanner : Assembling units

Please see the image to get the list of items.

Alt
List of items
  • Attach the HDI 100 scanner (1) to the table-top tripod (2) head by hand-tightening the head knob.
  • Connect the Power and Ethernet Cordset (3) to the Power/LAN connector port on the scanner. Then, hand-tighten the cordset.
  • Connect the Power barrel jack of the Power and Ethernet Cordset to the Power Supply.
  • Connect the Ethernet RJ45 plug of the Power and Ethernet Cordset directly to the computer.

Now that the scanner is all set, let's set up the Rotary Table (5)

    USB to RJ11 cable (6)
  • Connect the Power Supply Adapter (7).
    Alt
    Power Supply (7)
  • Connect the USB connector of the USB to RJ11 cable to the computer.

Now, you can plug the power cords of both the scanner and the rotary table to the power supply.

Configuring the 3D scanner software

  • Make sure the scanner is ON, connect the USB license key (found in scanner box) to the computer then open the FlexScan3D software.
  • Go to the Scanners tab, our scanner should be read as HDI 120.
  • Click on the Auto-Configure button to configure the LAN connection between the PC and the scanner (requires administrator password-see _Space.URI staff for assistance).
  • The connection is now ready and the scanner should show some data on the right hand side of the screen.

Creating a new project

  • To create a new project, select New from the Project tab. Type a project name and press OK to proceed.
  • Make sure to leave a ~50 - 90 cm distance between the scanner and the rotary table. The scanner should be pointing to the center of the table.
  • Put the calibration (checkers) board facing the scanner.
  • Make sure that there's no high illumination, reflective or shiny objects between the scanner and the board or behind the board.
  • Check that the checker board fully appears on the two scenes on the right-hand side of the screen with minimum RED and BLUE areas (perfect scene will appear in grayscale).
  • You can modify the exposure value to get the best result using the Exposure slide in the right-hand side of the screen.
  • Replace the calibration board with the object you need to scan and modify the exposure configuration if necessary.
  • Select the scan tab. The FlexScan3D software is smart enough to provide the optimum configuration to your scene. Check the Rotary, the easy scan and the live scan boxes to benefit from its capabilities.
  • Press the easy scan red button to start scanning.
  • When the scan is finished, check the boxes beside all the scanned images thumbnails then click on combine from the combine tab.
  • All the thumbnails should be combined in a single thumbnail now. Check the box beside it then select Finalize from the combine tab. Press OK to create the finalized 3D object.
  • A new thumbnail should be created with name: ***_final. You can export it by checking the box beside it and clicking Export in the scan tab.
  • The default export format is .obj but you can alter this by clicking on the arrow in the Export button in the scan tab.
  • Select the destination folder and press OK.

Caution

The network connection between the PC and the scanner affects the windows default LAN connection settings. Always remember to restore the network default settings (i.e., DHCP) after finishing to avoid any conflicts.


To Reconnect the Internet

  • Reconnect the Ethernet cable from wall to the back of the computer.
  • Click the internet access icon on the lower right hand corner of the screen
  • Select 'Chang adapter options'
  • Right click on 'Ethernet'
  • Select 'Properties'
  • When prompted ask _Space.URI staff for assistance.
  • Click on 'Internet Protocol Version 4 (TCP/IPv4)' then click 'Properties'.
  • Select 'Obtain an IP address automatically' then click 'OK'
