Thanks. I will look at this when I get a chance. I may end up
reworking an old Bezier spline driver module to straight step direction
code if it comes to that.

For simple simker EDM I implemented reversing in a gcode loop sensing an
analog input:
http://code.google.com/p/sector67-sandbox/wiki/FrequencyBasedAnalogInput
this was simple for my application, could stand to be refined somewhat, and
would get complicated for anything but straight down/up.

If this is purely a die-sinking application then I suggest not

Do the whole thing in HAL with a custom component, and maybe you
