FAQ #2.10:

I am using the Motorized-Stage Configuration of VisionGauge® and sometimes - for no apparent reason - the stage and / or column starts moving on its own.

Solution:

In the vast majority of cases when the stage and / or column is moving on its own, it's because the external joystick is not properly calibrated. The "un-calibrated" joystick is sending "move" commands to the stage and / or column. To rectify the situation, we suggest that you carry out the following steps: a) shutdown VisionGauge® b) erase the file called "VisionGauge.joy" located in the main VisionGauge® sub-directory (probably "c:\VisionGauge") on your computer's hard disk.  c) startup VisionGauge®. VisionGauge® will walk you through the different steps required to calibrate the joystick. This should solve the problem. Please note that you can use password protection (described in chapter entitled "High-Precision Measurements" of the User's Guide) to stop operators from un-calibrating the joystick.
