I did a laser/web cam with mach using point cloud software written by (art) same guy that made mach3.
I made up a small carriage for the Phlatprinter with the correct web-cam/laser pointer angles and tried some test, but never really got any good results, I think because of the lacking point cloud software.
I hope that you are more successful.
Here is the YouTube video of it in action






The material is 1/4" foam and the bit is 1/16" Attached files 3D Probe Stand.cnc (20.9 KB)Â 3D probe Stand.skp (440.2 KB)Â

 

What is the concept here Mark? Is the webcam supposed to convert points of light from the laser pointer into useful data? It sounds interesting.

 

Sorry I should have posted more info on this.
Here is one guy that shows you how its done. This is a great page for DIY web-cam/laser scanners
