    Anyway the purpose of this post is to describe a new app I put together today for laying the master rail straight. I decided it would be easier to use a taut wire rather than the laser for this and a cheap USB microscope.
    [...]

    The microscope is attached to a hiwin carriage and the new app accurately locates the wire allowing you to zero the tool then reports the error as you slide the carriage back and forth.
    [...]

    Nothing new in the process that other people have performed other than the app that lets you achieve excellent accuracy with little effort.
    [...]

    The wire locating algo is quite different from the laser gausian model and seems extremely robust.

    With apologies for absence ... it's been a while since I was here :

    That sounds like a great development, Joe
    I obviously need to read the next couple of pages, but please let me join those requesting that you share the App
