Art,
If you also open up the "point knob.txt" file, you will see that all z values are about 2.5xx inches in elevation.   I have another file that all z values are exactly at 3.500 inches.   

In other words, the output is roughly equivalent to a xerox copy.       I'm almost there.  Just one more dimension. 
 
Thanks,
Dave

Here's a picture of a knob.  The txt file is also included.

On the right monitor screen, I have been able to improve it some.  But I get a double line.  One red and a parallel white line.   I doubt if this is good.

Tonight I hooked up the laser the camera and I:

1st, I calibrate and I get a Scan Angle.  (mixed results and never got the correct angle and correct z distance at the same time)

2nd, I change the feed rate to 5

3rd, I change the StepOverY to .01 

4th, I changed the ScanY to 3 (because my object is 2 inches wide)

5th, I press Scan  (The table moves 3 inches at 5 in/min then returns). 

6th, I run MachCloud and view the results.   My results actually look like my object except the thickness is zero.   My cloud is laying on the zero surface. 

I'll try to get an image in just a minute.

I've got problems viewing the video on screen both left and right hand monitors.

I'm not sure what I'm supposed to be seeing in the right monitor.   What ever I'm seeing, it doesn't look correct.   

There is a slider between the monitor screens.  What does this do.  When I raise it, I seem to get some speckles on the right screen. 

The format and source buttons are not reliable.   I crash about half time when I touch these buttons.   

Those are some of my results. 

Over all,  success, I'm making progress.

I got mine too.   I didn't measure my line, but 1/64 of an inch is smaller then my laser's line.  I'll measure it tonight.  Maybe I'll get the camera and laser mounts made tonight too.

Tom,
The light bulb is not burning to brightly right here. 

Your description makes me think that the program scans a narrow camera view in the X direction, then translates in the Y, a distance equal to the narrow view.  Then repeats the X scan.  How am I doing?   

Makes me think of a Zamboni cleaning ice, except all scans are directly adjacent to each other.

Tom,
I went back to Arts pictures to confirm your description and wow you are correct the laser line is in the YZ plane.   I thought the laser line would be in the XZ plane.   In another thread, Art indicated that the gantry movement was in the Y direction, which doesn't make sense to me.   I thought we'd want to step in a direction perpendicular to the laser line.   

What am I missing?

hi every time i try to start the video window or video probe i get DRIVER WATCHDOG TRIGGERED what is this & can i get over it?
thanks mick winship

Mick,
What version of Mach3 are you running?  It must be R2.60. 
I take it that you have a camera installed?  Is the camera installed correctly?  Does the camera's video software run without Mach3 and run correctly?
