I too am sorry to hear about Tom. He was a real giant in video probing. I knew he had health problems but since I don't visit this page that often was surprised to hear the bad news. We had emailed each other many times. It explains why he did not repond to an off line email I sent him about 2 weeks ago about a new green laser that I wanted his opinion about.
While Tom was working more specifically on video probing my associates have been working on topographical scanner that at this time doesn't use mach3 .
A preview of what can be done can be seen at
www.grasp3d.com . The software is not quite ready and there is a patent that is being processed. So there are no need for questions at this time. We are hoping all is done by the end of this year.
