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
