M3 FAQs

Q: HOW DO I PERFORM A GAGE CIRCLE CONSTRUCTION?

A: The “gage circle” is constructed from (2) probed line features, and (1) created circle feature of a desired gage diameter.

Procedure:
  1. Measure the (2) line features that will contain the constructed gage circle.
  2. Create a circle feature, with a specified diameter. This diameter will define the diameter of the gage circle construction. The positional location of the created circle is irrelevant.
  3. Select the “Measure Circle” button.
  4. Select the (2) probed line features and the (1) created circle feature from the feature list or part view.
  5. Press “Done” to complete the gage circle construction.
  6. Both the created circle and the constructed gage circle will remain in the part view and feature list. These (2) circles will be the same diameter and at the same positional location. The created circle can then be deleted, if desired.

Q: WHEN I MEASURE FEATURES IN MY M3 SOFTWARE THE FEATURE SIZES ARE INCORRECT BY A LARGE OR SIGNIFICANT AMOUNT. WHAT COULD BE THE CAUSE?

A: More than one cause can be attributed to incorrect feature results:

  1. Check that the currently selected magnification level on your measuring machine, matches the magnification selector it the M3 software.
  2. Confirm that the unit type you intend to observe results for is the currently selected unit type in the M3 software. Check the unit selector button located on your top toolbar.
  3. Confirm that the Magnification that you are using has been calibrated in the Video Setup screen, found in the M3 settings menu. If you do not have access please consult your supervisor. See the M3 Setup guide for more information on teaching pixel size in the M3 software.
  4. The encoder resolution for your system may be incorrect. Please select the simple crosshair tool. Position it at the edge of a known length standard. Zero the X axis DRO and travel the standard length. Observe the results and make adjustments to the Encoder resolution or direction in the Axes Setup screen of your M3 settings menu.

Q: WHY DON'T I GET POINTS WHEN I TRACE THE EYE MEASURE PROBE ON A FEATURE EDGE IN MY VIDEO SCREEN?

A: This can be caused by a poor edge contrast within the given Field of View. The manual edge teach routine can be performed to improve edge detection capability for a specific edge profile.

Procedure:
  1. Select the Measure Logic video probe from the probe menu.
  2. Press or click and hold on the edge that you would like to measure.
  3. Position the magnification box so that the small target circle settles on the zoomed portion of the edge you are measuring.
  4. Release your finger and wait for the teach points disappear.
  5. Repeat the measurement with the Eye Measure Probe.

Making adjustments to your machines lighting may also improve the edge point detection of the various M3 video probes.

Q: HOW DO I MEASURE LINES AND CIRCLES WITH THE MEASURE LOGIC PROBE WITHOUT THE FEATURE BEING “FINISHED“ AUTOMATICALLY?

A: Any feature can be measured in a way where a “Done” button press is required to complete the measurement. Simply request the measurement explicitly, that is, press the measure feature button for the feature you are measuring. Once the desired number of points is reached, press “Done” to complete the measurement.

Q: MY PART PROGRAM DOES NOT SUCCESSFULLY PLAYBACK FOR SOME OF MY PARTS. I SOMETIMES GET AN ERROR MESSAGE INDICATING THAT THE REQUIRED NUMBER OF POINTS HAS NOT BEEN FOUND. HOW CAN I ADDRESS THIS?

A: More than one cause can be attributed to inconsistent part playback performance:

  1. Confirm that features chosen to serve as playback registration features, represent significant positional import to the target part coordinate system. For some parts this is difficult, however remember that these registration features do not need to have any other value for the inspection routine, and can even be deleted from the feature list, so they are not included in the routine results.
  2. Increase the Search Zone setting, found in the program edit properties. This search zone setting controls how many pixels the M3 software will search in playback, for a given edge, and from a recorded nominal point position. This value represents the entire search zone in pixels, including both directions away from a nominal point location.
    Procedure:
    1. Open the part program that you would like to open the playback search zone for.
    2. Press play to initiate playback.
    3. Press the “Edit” button at the top of the feature list.
    4. Increase the current search zone value. Perhaps start by increasing by a factor of .25, and increment up until the value is doubled, checking playback at each change.
    5. Save the part program when the desired value is determined.
  3. Decrease the minimum number of points required for a successful measurement in program playback. This setting is found in the Program setting screen, found in the main M3 settings menu. The value should be entered as a percentage of the total points to constitute a successful measurement.
  4. Confirm that the lighting is sufficient and that there are no other significant changes for the video image, as it appears. This can be confirmed by identifying problematic feature measurements, and attempting to measure them in non-playback, or interactive mode.

Q: I HAVE ADDED A TOLERANCE TO A FEATURE INCORRECTLY AND I WOULD LIKE TO REMOVE IT. HOW DO I REMOVE A TOLERANCE FROM A FEATURE?

A: When viewing the detail view for a feature, the currently applied tolerance types can be viewed, added, and removed from the “Tolerance Entry” feature detail screen. Pressing a tolerance button from the bottom toolbar will add or remove that given tolerance for the selected feature. Newly removed tolerances for a feature will appear with a “Red Colored” slash through the entry field. This tolerance will be removed from the feature and the screen the next time the tolerance detail view is accessed.

Q: I AM APPLYING A TOLERANCE TO A FEATURE THAT REQUIRES A REFERENCE FEATURE SPECIFICATION. HOW DO I SPECIFY THE REFERENCE FEATURE TO BE USED FOR MY TOLERANCE?

A: Reference features can be specified for Parallelism, Perpendicularity, Angularity, Concentricity, and Runt out tolerance types.

When one of the tolerance types above is applied to a given feature, the reference feature dropdown list will be displayed in the Tolerance feature detail screen, directly to the right of the tolerance value field, as seen below:

IMPORTANT: Only features measured previous to the feature being tolerance can be specified as a reference feature.

Q: HOW CAN I RENAME A FEATURE?

A: Feature re-naming can be performed from either the Feature Detail view, or from the Report view.

Feature Detail View:

In the “large” Feature Detail view select the feature whose name you want to change. Select the Feature Name field in the top left corner. The name field will turn green indicating a new name can be entered. Press the “Done” button in the bottom right toolbar to accept the new feature name.

Report View:

In the Report View select and highlight the report line for the feature that you would like to change the name of. Press the “Edit Cell” button from the bottom toolbar, some feature lines will turn pail green, indicating they can be edited. Select the Feature Name field, the name field will turn darker green. Type in the new feature name and press the “Done” button to accept.

Q: HOW DO I PRINT ONLY SOME OF THE COLUMNS FROM MY CURRENT REPORT VIEW?

A: Column selection can be used for printing and exporting report data. When you select a report column by pressing, or clicking, in the column header, the selected column should become highlighted. Only highlighted columns will be included in exports or printouts.

Q: HOW DO I RE-CENTER, AND RE-ALIGN MY CROSSHAIR?

A: The simple crosshair can be translated and rotated within the field of view. To re-center and re-align the crosshair click or press and hold on the pan/rotate tool button, found in the top left corner of the video window. The crosshair will re-center and the rotation angle will be “zeroed”.

Q: HOW DO I SPECIFY A ROTATION VALUE FOR MY SIMPLE CROSSHAIR.

A: Press and hold on the Q Axis DRO button. A Q Rotation entry field will be displayed. Entered the desired angular rotation and press “Done” to rotate the crosshair.

Q: HOW CAN I SAVE A COPY OF THE CURRENT LIVE VIDEO IMAGE, TO A FILE?

A: M3 VED systems all support Image Archive capability. To archive an image:

Procedure:
  1. Set the camera image view to occupy the main viewport of your M3 software.
  2. Press the “Markup Menu” button(pencil icon) in the bottom toolbar.
  3. Press the “Archive Image” button from the markup sub-menu.
  4. An image file will be saved to your default images export folder.

Q: I HAVE CONSTRUCTED A CIRCLE, LINE, DISTANCE, OR ANGLE FEATURE FROM OTHER FEATURES, AND THE RESULTING FEATURE IS NOT THE ONE I NEED. HOW CAN I CHANGE IT?

A: Most feature constructions have additional feature result “sub-types”. As an example, if you construct a distance between some features, you may be looking to calculate the farthest, nearest, or center distance between those two features. If you are measuring a line between to circles, you may need to change the line to the alternate tangent. For any case, feature subtypes are accessed by selecting the desired feature from the feature list or partview, and pressing the change feature button, found in the bottom toolbar(button icon appears as triangle design incased in a circle). The currently selected sub-type for a given feature will be reflected in the partview, and indicated in the feature detail view(s).

Q: WHEN I LONG PRESS, OR CLICK, ON MY M3 SOFTWARE I CANNOT ACCESS THE EDGE TEACH FUNCTION, OR THE GESTURE WHEEL MENU FUNCTION. I ONLY SEE A RING OR HALO AROUND MY FINGER. WHAT IS WRONG?

A: This is due to a Windows 7/8 setting that takes control of the long press function, interfering with operation in the M3 software.

Procedure:
  1. Access the Windows 7/8 Control Panel. If required, set the view type to “small icons”.
  2. Select the “Pen and Touch” control panel screen.
  3. Select the “Touch” tab from the top of this screen.
  4. Select the “Press and Hold” touch action item from the list.
  5. Press the settings button and uncheck the box for “Enable press and hold for right-clicking” item.
  6. Confirm settings change using the “OK” and “Apply” Windows buttons.

Q: HOW CAN I PERFORM A BACKUP, SO THAT I CAN RESTORE MY M3 SOFTWARE SETTINGS AT ANY TIME?

A: The M3 software manages all of its software settings files from within the Metlogix\Settings folder in the Windows 7/8 Public Documents folder. Settings files for general operation settings, error correction, and camera settings will all be contained in this folder. Simply make a backup of the entire Settings folder and place in a safe location, preferably on a different computer.

Backups of the settings can also be restored from the Metlogix\Backups folder. The core settings files are updated to this folder at some regular interval, and date stamped for identification. These files can be copied, renamed, and placed into the Metlogix\Settings folder to restore these system settings to the time when they were originally generated.

WARNING: The operations above can have significant impact on the functionality of your M3 system. Please consult your Metlogix Representative prior to manipulating these files.

Q: WHEN I LAUNCH THE M3 SOFTWARE I RECEIVE AN ERROR THAT THE INTERFACE BOX HAS BEEN DISCONNECTED OR RECONNECTED, AND THESE MESSAGES PERSIST. THE SOFTWARE IS NOT FUNCTIONING PROPERLY AS A RESULT. WHAT COULD BE THE CAUSE OF THIS?

A: This typically indicates that your USB scale interface box is not detected by the windows system. This can be as a result of that it is not powered on, the USB is disconnected from the PC, or because the drivers have not been successfully loaded, or have failed.

Please confirm that the Metlogix Encoder Hardware has been successfully installed in Windows:

  1. View the Printers and Devices screen, from the start menu in Windows 7/8.
  2. If the device displays with a yellow alert icon or red X icon, the driver is either not installed or has failed. If the device display screen shows the “Metlogix USB 4 Axis Card” device, as seen below, you have successfully completed the Metlogix Interface hardware installation.

If the drivers are not correctly installed, please see pages 7 and 8 of the M3 Setup Manual. The Setup Manual can be downloaded here. (Link to M3 Setup Manual PDF.)

Q: MY VIDEO IMAGE IS NOT DISPLAYED WHEN I LAUNCH THE M3 SOFTWARE. INSTEAD I SEE A BLACK AND WHITE IMAGE OF SOME SHAPES WHERE MY VIDEO WOULD TYPICALLY APPEAR. WHAT MAY BE CAUSING THIS?

A: The black and white image displayed is a Metlogix sample bitmap image that we utilize as a place holder in the event that no video signal is detected for the current M3 configuration.

More than one cause can be attributed to the video signal not being detected:

  1. A valid camera signal, and licensed Metlogix Hardware, must both be detected by the Windows 7/8 system in order for an image to appear in the M3 software.
  2. First, access the M3 settings screen and confirm that you Image Source has been specified in the “Video” Setup screen. Restart the software. If you still have no image, continue below.
  3. Exit the M3 software. Power off the PC. Confirm that USB cables and Power are connected from both your Metlogix source(Encoder Box) and your camera source, from you measuring machine. Restart the PC and your M3 software. If you still have no video image, continue below.
  4. Confirm that the Metlogix Encoder Hardware has been successfully installed in Windows:
  5. View the Printers and Devices screen, from the start menu in Windows 7/8.
  6. If the device displays with a yellow alert icon or red X icon, the driver is either not installed or has failed. If the device display screen shows the “Metlogix USB 4 Axis Card” device, as seen below, you have successfully completed the Metlogix Interface hardware installation.
  7. If the drivers are not correctly installed, please see pages 7 and 8 of the M3 Setup Manual. The Setup Manual can be downloaded here. (Link to M3 Setup Manual PDF.)
  8. If you still do not have a video image, please consult your Service Representative for assistance.

Q: I HAVE SAVED PARTS, REPORTS, AND IMAGES FROM MY M3 SOFTWARE. WHERE CAN I FIND THEM ON MY SYSTEM?

A: After the first launch of the M3 software a folder, named “Metlogix”, will be created at the following path:

[Drive Letter]:\Users\Public\Public Documents\

This folder can also be reached through the Win7 libraries folder in Documents\Public Documents.

The Metlogix file output folder will contain the following sub-folders:

  • Backups: Will contain settings, and error correction backup files. Backups are generated every 7 days by default however this backup interval can be configured within a Metlogix configuration file. Please contact your Metlogix representative for assistance with making this change.
  • Exports: This folder will contain measurement data export files. Files containing measurement data will be exported from the M3 software's data view to this folder location in either .txt or .csv format.
  • Images: This folder will contain images saved from the Image Archive feature of the M3 software.
  • Parts: This folder will contain saved part program files from the M3 series software. Files saved to this directory will have the extension “.mlxpart”.
  • Settings: This folder will contain the core settings files of your M3 software installation. The setup file “SettingsM3.xml” will be stored in this folder. This file contains all major file settings parameters for your M series software installation. This folder may also contain additional configuration files(metlogix.ini), camera settings files(LastDeviceDetected.xml), or error correction files(NLECnew.txt).

**The Backup, Export, Images, and Parts folders can be assigned to custom output locations or folders using the “File Locations” settings screen, located within in the main settings screen.
