Hi Don,
thinking a little more about your situation. I suspect that learning to use a CAD/CAM may be a hurdle.
Evidently you are quite capable of conversational programming and manual programming.
I myself use MillWizard from NFS ($75), it adds what amounts to conversational programming. There is one feature of
that program that may appeal to you. Its the 'Polyline' feature. You program a series of points with either lines or
arcs between each point and MillWizard will generate the Gcode.
I have attached a couple of pics that might explain it a little better. The first pic is where I have programmed a number (5)
points (X, Y coordinates) with a straight line in between each. The second pic is the toolpath that MillWizard generates.
There are other options as well, tool offsets, direction of cut etc. While it is tedious to program in the points its perfectly
doable and in fact very simple.
Such a method would not be practical if you had a point cloud of a thousand points but probably useful up to 100 points.
Download a copy and try it. As a demo you can't save the Gcode but is in all other ways fully functional. The advantage of
MillWizard is that you can be producing Mach compliant code within 1/2 an hour.....its so straight forward.
