Hi Devmonkey

I downloaded and set up the camera software from Github.
setting up is quite a process, a mate who is a far better programmer than me led me through the environment variables setup. I am not used to this sort of programming environment.
Once installed correctly the software compiled without an issue.

I was only using the webcam on my laptop and a hand held laser line (not point) generator. It worked very well.

A logitech webcam was also tried it worked but there were strange fresnel like circles produced with the laser. The logitech camera had a quite large lens. The laptop camera did not display the same aberrations. its camera is tiny.

I also tried a fuzzy pencil line drawn on paper that worked OK too.
A piece of wire should be no problem.

Over the weekend when I have time I will set up a test on a granite surface plate with some precision gauges. and a proper camera with and without a lens on a stand.

It will be very interesting to get a better idea of repeatable accuracy. I am sure it will be very good.

Congratulations Joe, great job.

Regards
John

PS:
I have started to draw up the flat surface generator I described,
I want to make it 90% from Laser cut 5mm steel plate. Using a single universal beam as the main frame (100ub 23) I know that that profile is available in Australia and the UK Hopefully Europe and the US too. It will hold an up to 100x100mm RHS Workpiece. To be used as linear rail support beams for routers and mills.
I hope it works! There is only one way to find out.
