DIY Laser levelling using webcam and laser level

**Kitwn** · 16-09-2020

Romeo,
I ended up following Joe's route and going with taut wires (we actually owe John McNamara for that idea) but went even more old school and simple than you are planning using a simple electrical contact to detect when my probe was just touching the wire. Details here if you're interested http://www.mycncuk.com/threads/13627...ith-Taut-Wires

Hi All

Firstly, glad to hear you have moved to the Apple isle Kit, its a great place to live.
I have made the project open source.

I decided to open a GrabCAD page and have posted the CAD files there. I will update them as the design progresses. The model was built with AutoCAD 2017 so anyone with that version or later can view the files.

You can also download a free viewer from Autodesk. https://knowledge.autodesk.com/suppo...-TrueView.html

The files are located on GrabCAD here:

Regards
John

Hi Joe

Firstly I am very glad to hear you are fit and well in these difficult times.

Thanks for the heads up on using standard IO as a way of getting the data out.
Soon it will be time to start building a machine to test all the hard work done by many hands.

Regards
John
