Hello Hbaba,

Here is a drawing of my setup. I show the camera and and laser axes in the XZ plane but Mach3's 3d Probe Plugin presumes that the camera and laser axes are in the YZ plane.
http://www.machsupport.com/forum/index.php/topic,5023.msg42913.html#msg42913It is important that the laser and camera axes intersect at 90 degrees so that the laser plane is parallel to the camera lens detector planes.
> Laser angle to object
Laser angle is 30 degrees clockwise from Z axis.
> Camera angle to object
Camera angle is 60 degrees counter clockwise from Z axis.
> Camera distance to object
See drawing for layout.
-Camera Model/Spec
3Com Watchport/V CCD USB Webcam with 648h by 480v square pixels for VGA format. I use a 12mm focal length f/2 lens. This gives the camera a 14 x 18 degree field of view. At the target that is about 1/2 inch square.
> Also, any plugin settings you can share would be awesome.
I use a 1/4 inch square bar to calibrate. The corners are slightly rounded since this is just extruded stock. I have a scan of a key.
http://www.machsupport.com/forum/index.php/topic,6596.msg44274.html#msg44274Calibration would be more accurate if I milled the calibration bar so that the bar surfaces intersect at a sharp 90 degrees. I have not measured anything in the point cloud so cannot yet comment on precision. My probe is being shown at the CNC Workshop in Illinois right now. I will have it back in a week or two and will then be able to do more testing.
