    Hi

    I have a load of plastic control boxes that i need to machine. What is the best and most accurate way to find the center for zeroing?

    I have the 2010 screen set now which has great scripts for zeroing but unsure if any of the can do the job.

    Heres the box

    Isn't the 2010 screenset more aimed at probing?
    Regardless, if you know the size, touch of two adjacent sides, and work it out from there (half probe diameter + half width/length will give you centre zero)

    Either that, or you have to touch of opposing sides, and calculate the centre. Simply take the position from the touch on opposing sides and average them out (add them together then divide by two - you don't need to worry about probe diameter as it cancels itself out when averaging).

    If you've got lots to do, I'd be making a repeatable jig/stop so you don't have to re-centre for every box. It doesn't have to be fancy, just a couple physical stops so you can repeatably clamp the box in position.

    Use the X an Y pocket routines in the 2010 Probing Wizard.

    It was intended to be a better interface for Mach3, with automatic Z zeroing during tool changes.
    The probing portion was added later, and was never the intended goal. So I wouldn't say it's "aimed" at probing.

    Thank you.

    I don't suppose you have any examples on how to use it to find the center of a box. Similar to the one I have posted?

    Find left edge, zero DRO, find right edge, set DRO to half the displayed value, zero is now centre line of part.
    Repeat for front & back.
    It's so quick and easy I don't see why automation is required?
    You think that's too expensive? You're not a Model Engineer are you? :D

    Jog over the box, and down into it.
    Check the box to zero the X and Y coordinates.
    Press the X Pocket button.
    When it stops, press the Y Pocket button.
    Done

    What kind of probe does that need for a plastic box?

    Fair point. I think I'll have to maybe stand my edge finder up and quickly move it as it probes......

    You'd need to use an actual probe, rather than the tool and a conductive plate.

    But you could use the touch plate, and manually move it from side to side if you are quick enough.

    Impressed with the screen set. I just used a old tool and stood my probe plate vetical against the side of the box and probed z and y. Worked a treat..
