If I am not mistaken, the simplest method is to fix the wire path and
just move the table.

this requires a simple X-Y movement and not a 3rd or 4th axis. That
makes it much more simple.

The software problem is to sense some process related value and feed
that to the tool path.

this might mean a dynamic feed rate.

getting the 'value' back into the software could be as simple as
using a pair of high and a pair of low inputs.

if the amps (or volts) measured is between a pair of set values, then
the 'current' feed rate would be used.

if it fell in between the high and highest, then a somewhat slower
speed. If it fell between low and lowest, then a faster speed. or
vice versa, depending on what is being measured.

the other simple option is to use an analogue signal to maintain the
feed rate, but I thing that would be a lot of work.

I see that a reverse tool path would be beneficial, but that would
only need to be a very few in the even the system shorted. if a full
reversal were required such as if one cut an interior shape that
needed to be left, then either cut the wire and rapid out, or a full
line reversal. that I thing would be a PITA.

Any way you slice it, Wire EDM is complicated from the software side.
