Configuring RevWorks for MicroScribe Digitizers

 

The MicroScribe digitizer requires no hardware configuration in order to use. However, for 3D series arms you must make sure that the machine is in its proper "home" position before turning it on. When a 3D series MicroScribe is turned on in the home position, it is automatically calibrated. For M and G series arms there is a separate Home button located next to the USB connection point that may be pushed to home the device after power is provided. If not placed properly in the correct home position, any data provided by the device is corrupt even if real locations seem to be provided. When RevWorks first attempts to communicate with the device, it automatically determines the type of device and the form of communications being used, either USB or serial and connects as appropriate. If the device needs to be Homed the MicroScribe Calibration Wizard automatically displays and leads you through the homing process.

To Configure RevWorks for USB Communications with a MicroScribe M, i, or G Series Digitizer

RevWorks automatically detects when a USB connection is being used with your digitizer. There are no configuration options presented.

To Configure RevWorks for Serial Communications with a MicroScribe G, i, or 3D Series Digitizer

  1. With the MicroScribe connected and powered up, from the RevWorks toolbar, select , or select Options… from the RevWorks menu.

The Options dialog appears.

  1. Select the Devices tab.

  2. From the Current Device drop-down list box, select MicroScribe if it is not already selected.

The Options tab automatically reflects configuration options for the digitizer.

  1. To have RevWorks automatically search for your MicroScribe digitizer when using the serial communications interface (preferred), select the Auto Search checkbox in the Communications group.

  2. To manually set the serial communications parameters, deselect the Auto Search checkbox in the Communications group.

The Port and Baud Rate fields become available for data entry.

  1. On the Communications group, select the communications Port to which you connected the digitizer.

  2. In the Communications group, select a Baud Rate of 9600, 14400, 19200, 38400, 57600, or 115200

  3. Select OK to accept the specified options.

Your MicroScribe digitizer is now ready to start.

Probe Approach Tolerance

RevWorks tracks probe movement to assist in determining the proper offset direction for features measured with a ball probe. The sensitivity for probe movement may be adjusted by changing the Probe Approach Tolerance. The Probe Approach Tolerance specifies how much the probe must move before that movement registers as probe motion for the sake of determining the offset direction. The default value of 2 millimeters should be adequate for most measurements. If you are measuring features, such as a bore with a ball probe that is nearly the size of the bore, you may want to reduce the Probe Approach Tolerance, if the probe cannot be moved at least the specified amount before the first point is taken. RevWorks may not be able to determine the correct offset direction unless you approach the first point of the feature by at least the distance specified by the Probe Approach Tolerance. If RevWorks seems to be randomly offsetting in the wrong direction, the value for Probe Approach Tolerance may be too small.

Note: The Probe Approach Tolerance must minimally be set larger than twice the inherent accuracy of the device.

Note: RevWorks displays measurements in the same units as the currently active part or assembly document. You can enter values in any other supported unit of measure by adding the recognized abbreviation after the value you enter.

To Configure the Probe Approach Tolerance

  1. Select , or select Options… from the RevWorks menu

The Options dialog appears

  1. From the Current Device drop-down list box, select MicroScribe if it is not already selected.

The Options tab automatically reflects configuration options for the digitizer.

  1. In the Probe group, change the default value for the Probe Approach Tolerance.

  2. Select OK to accept the change.
