well, at least I can tell its a skeleton..

  Narrow your FOV, it may be too high, dont worry about height, just set it to 50 degrees, Im curious if that stops the stretching or smooshing..

 Not too bad for a first attempt though.. at least its recognisable..

Yup, M3P files stands for "Mach 3 Plugin" and they are autoinstalling, I just copy them to my desktop, and double click it. It will go away and install itself to the right spot..

After that, you need to run MAch3, select config/config plugins, check the enable box beside the "3d Probing Plugin" lline, and restart mach3. The video prober will then appear in your menus'.

( M3S files are mach3 screens... same deal.. )

Buck:

 Should work to any distance, but small items will get lost , the closer you are the better , but too close and the laser line gets fuzzy, I use some
filtering to calcuate the center of even fuzzy laser lines, ( the red line shows center of line offset from the white raw data, but Im not sure of the total
spec of it, Ive only run a few hndred scans, overall, they keep getting better, still lots to do yet though.. complex stuff, Ill take a few days break from it now..wait to
see what others get for results..

Dave:

 For this version at least, it scans only a linear section. When its all working Ill add a rotary scanner, but
its a challenge to get it linear only as yet. The idea is to allow you to copy a large carved door or something that lies on the
table in multiple stipes of aquisition. Lots of hurdles to cross, but its an incremental process..

Hi:

  When you go to calibrate, make sure you slide the threshold upwards till you can see the entire width of the calibration cube. Distance to the camera may be a bit off , I sometimes get the same thing. Ive working on that , but the only ill effect is registration of the striped data if you scan in the x dimention, I only scan in the Y at the moment.
  If the points cloud is empty, try changing the "Ignore points less than n in Z" to -100 and see if it then posts points. If the nagle gets computed backwards, then its possible your points are upside down..

  To compute the depth, the system finds a point on the upper point of the cube, and makes a 3d plane equal to the angle of the laser and uses that as an intersection plane.. since Ive only used it here, I cant verify it works on all lase rplanes, but Im curious what you get if you allow any point to be set. If it scans, then the only thing that woudl stop points coming out is the Ignore Points setting.. Let me know what you get..

One other note:

  This thing is pretty CPU intensive, so performance will vary.
