Hi Bryan Howard

Gee It was great to see this project moving again.
Devmonkey inspired me when he first posted this great idea

I am still very keen to build an open source surface straightening device using a webcam and stretched wire. Using a small milling cutter to flatten a surface point by point. All I need is a signal that tells me the webcam software has found center of the wire, from a PC or microprocessor via a hardware port. Ideally a digital Value +- signal to enable me to find the wire more easily when moving the camera over the wire.

I know I can build the hardware and provide the XYZ Motion control, Its just the webcam reading code that is beyond me.

Extensive testing that proves the accuracy of stretched wire was done, all my results were posted earlier on this thread a few pages back.

I also posted an early concept open source 3D model on Github

Cheers
John
