    Hello All,

    This is my first post on the OpenBuilds forum, but so far have been loving browsing the ideas some great minds have had. I'm currently working on designing a pallet system that will be belt driven through a series of machine components, and one of the many design constraints is that the top surface of the pallet (24" x 18") needs to be flat to .3 mm from its highest to lowest point. A leveling/adjustment mechanism is already being worked on, but the current challenge I foresee with this is the ability to measure this flatness so I know what adjustments need to be made.
    I had a few ideas in mind (using a positioning indicator probe on a gantry system, having a laser tripping system oriented parallel to the surface that's lowered at various X and Y increments), but would love to know if any of you have seen or created a flatness measuring system and would like to offer any insight. Thanks in advance, and good luck with all your builds!

    Hello @Jesse Henkel
    I do not know much on the subject but what comes to mind is you could possibly work up a sweeping laser on one side with a receiver on the other for a hopefully inexpensive way to measure flatness.
    This may interest you - Laser - Use Of A Laser To Measure Flatness
    All the best with your build, look forward to seeing what you come up with.
