    I am interested in making a Linear Stop using Openbuilds
    something similar to this
    http://rexelpoland.com/en/catalog/view/9/3/manual-length-measuring-stop-pr-1

    I would like to be able to Set a Distance and have it move to that position. but also be able to move it manually by hand if needed and have it report back the current length.

    Any advise regarding getting a arduino or other controller to do this would be appreciated.

    do you need a motor encoder on a stepper. I thought it was already built in

    Yes and no. Theoretically you can count steps but if you get it moving too fast it can lose track of them.

    So a Servo Motor would seem a better solution

    I wouldn't say so. For this I think a servo is a bit overboard. I'm guessing speed isn't a concern, so a stepper is probably the most economic route. You could even throw in a homing routine. How long do want to make this?

    Trying to make a Digital End Stop for cutting pieces to an exact length.
    like this http://proscale.com/products/woodworking_related/prostop2.htm
    but more automated. so i can set 10.4 inches and it will adjust to the exact spot needed
    so i can make accurate cuts.
    so it would likely be Arduino based, have a control keypad a simple LCD Display to show position
    I should also be able to slide it manually by hand without it loosing its position. thats why the servo or an encoded stepper
