When the wire is stretched between two points in two planes each with its
own XY table then the wire will touch the part as a tangent. There is
fairly simple math to compute where each XY table needs to be for the wire
to touch the part at a certain position. The XY tables need to know
nothing but simple G codes to follow this program.
