    Going to take this discussion/build to a forum that doesn't continually play with site settings.

    Thanks for that Gerry, it looks pretty much ideal for what I'm aiming to do.
    I just need something suitable running Mach3 now, as my only currently functioning mill does't run Mach!

    First - I know this is an old thread, but it says what I want to do.

    I need to do a contour map of an object and reproduce it in wood. It does not have to be accurate to the angstrom. I am trying to make a wooden insole for a shoe, so a 'bed of nails' digitisation would be OK and probably a 2mm grid would be fine enough.

    I would start with a plaster cast of the foot and then 'scan' it, before putting it through software to end up with Gcode.

    My probe is yet to be made, but I have about 20 4mm square 'pills' of QTC (Quantum Tunnelling Compound) and one of them could make a Z axis probe switch.

    So I am relying on the forum to give me some ideas, is there any bolt-on software to Mach3? (does Probe-it fit the bill or is there anything better on my virtually zero budget?).

    Help please

    Probe-It is ideal for contouring, but it doesn't really do Z digitising other than for basic probing for establishing heights.

    If a bed of nails approach would work for you, then Mach already has a free bed of nails digitising wizard included.

    It just demonstrates to me what a narrow subset of knowledge I have about Mach3. I will investigate today. Thanks m_c.

    I don't know if this would help you but I take an image of an item within a known size box or put a ruler in the shot, save in grey scale import it into Vetric Aspire and produce a 3d map you can also produce vector outline's of the imprint to clean up the imprint, save as STL file create the toolpaths save as G-code and away you go.
    But as plaster is white you might have to colour the imprint a little to get best results.

    Thanks Phill, but I don't have Vectric Aspire, and as I am only a 'poor old pensioner' It is out of my budget. If I were using a non-contact digitising method, then I would use alginate to make the cast.
