For the LDM to work properly it need to be calibrated in position. That is, the offset in X and Y of the laser beam compared to the probe must be typed into the software.
Measure the offset like this:
1. Go to Measuring Points tab - 3D.
2. Turn the laser on by checking LDM ON.
3. Click “Position Scanner manually” to open the positioning dialog.
4. Move the scanner head using the step-by-step movement buttons until the red laser dot is at the origin of coordinates.
5. Remember the X and Y position.
6. Turn the laser off.
