There is alot of software out there for cutting KCAM,CNC Pro,DeskNC, TurboCNC, Mach3, Foamworks etc. etc etc., and being close to finishing my machine I would like to know what are you guys using
thanks!

For CNC you cut the top first. Template cutting usually is bottom first so that the cut foam will settle into
the shucks and "compensate" for the kerf of the hotwire. It does not really compensate, it replaces one error
with another error but it is good enough for most applications, definitely good enough for combat. Any decent
CNC cam software will modify the tool path to compensate for the kerf and GMFC does this rather well. Cutting
the top surface first leaves the work in place WRT the reference surface (the top of the table.)
There are quite a few conceptual differences between template cutting and CNC cutting. The top first vs bottom
first is just the beginning.
Post some shots of your machine.
I have built 4 different machines with a few different people and am currently building a new one for myself.
The one Terry and I built has cranked out uncountable wings/fuses for combat, slope and even sport flying.
It has been a very prolific machine. The machine I built with my brother is up in northern California and It
is now in the hands of the guy who cuts all the Battle Floyds. That machine was stable at 10 mm/Sec, we found
that the foam became the limiting factor in cut speed, in the past it was always the machine.
