Troubleshooting Scanning Performance
Occasionally there can be some scanning preference issues that cause slow scanning speed and crashing. Please review the scanning troubleshooting steps below to improve these processes. Each computer installation is different, so the base performance of a computer will vary.
1. Hardware Scanning Requirements
- Make sure all cached and paged memory is being saved locally on the computer and not to a network drive.
Files and information can be saved to a network location after the scanning session as doing this during can create additional problems and corruptions.
- If you are scanning on a laptop, try changing the Windows power settings: the default configuration of the power setting is Balanced or another power saving configuration.
Changing the processor power management to 100% usage can reduce scanning lag.
- Turn the PCI Express Link stat power management to off and in the Intel Graphics setting to "maximum performance." These options are in the Change Advanced Power Settings under the Change Plan Settings in Power options under the Control Panel. These options are set to default to extend the lifetime of a charge of battery and is a trade off in performance.
2. Software VersionAs newer versions of Geomagic Software are released scanning performance may improve. Check to make sure you have the newest version here.
Confirm that when using the software you are running the software as an administrator. Temporary files are created when scanning that usually require administrative permissions to create.
3. Device Driver VersionVerify that you have the latest version of the Plug-in or SDK provided by the scanning vendor/manufacturer. This can change from scan arm to scan arm. Keep in mind that updates to the driver occur independently from the Geomagic Software.
For a Romer arm, with version 2016.1 and newer of Design X and Control X, we recommend using Hexagon RDS version 4.1 or newer. If you are using an version before 2016.1 using RDS version 3.6 has shown to be the most stable. Use the version that performs best in your local system.
4. Hardware Graphics DriverUpdate the graphics card drivers to confirm that they are the most recent version released for your graphics card. You will be able to locate these on the card manufacturer's website. NVIDIA Driver
5. Optimize Dedicated GraphicsIf using a laptop, ensure that the software is explicitly using the High-Performance Video Card setting.
a. Disable the on-board graphics card, usually an Intel. This is done in the Device Manager or through the system BIOS. To access the BIOS restart your computer. When the Windows logo appears on the screen press and hold F12. This will bring up a menu. Navigate to the switchable graphics section and turn this off.
b. Adjust the Program Settings to use the appropriate graphics card’. This will force Windows to assign Geomagic and related applications to use only the High-End card.
c. Turn off power saving mode in the graphics card control panel, if this option is available. This is usually only on a laptop and is used to conserve battery life.
6. Scanner OEM Recommendations
Scanner OEMs can have a specified recommended scanning profile. Check with the Scanner OEM to see if this exists.
Typically this is a reduced value of the full capabilities of the scanner and are specified in the scanner driver designed to stabilize slower computers.
7. Data collection method
Due to the hardware on the computer there may be an effective limit on the scanning performance. You can optimize the scanning settings in the software to prevent gather data that is not useful or to optimize the preference.
a. Scan in Ordered Points in Geomagic for SOLIDWORKS, Wrap, and Control. Scan in Points, not Mesh, in Design X and Control X.
b. Decrease the Grid Size to match the needed accuracy of the project. If there is need for .1mm scan density, there is no need to have grid spacing at .001mm. Go by half or a quarter of needed specifications. (0.1mm ~ .05mm or 0.025mm spacing).
