Is it possible to switch to metric units and can the thread pitch of the lead screw also be set to any free value, except the 20, 10 and 5 TPI ?

Phil,

Another update, metric units are now available. Also HPGL import. Back end now support more TPI/pitch, 20,16,12,10,5 TPI and 1.5mm and 1.25mm pitch. It is now easy in the backend to add more TPI/pitch, so if you don't see it here, PM me for specific value needed. Is easy to add now, but requires me to add it. Also a few ither minor features for re-centering cross sections and fuselage have been added.

Grasshopper for Rhino

I use Grashopper for Rhino to generate g-code when cutting complex geometry and run the code with mach3. Grasshopper is a parametric plug-in which is embedded in the Rhino 3d modelling environment. The complete four axis g-code updates in real time as the geometry is changed which reduces the time spent on preparing the cutting big time!

If you are after a 4 axis Gcode generator designed for foam wing cutters then cncworkbench maybe an option.

You can download a free demo version from www.rcplans.com.au

For a overview have a look at......

Eric, I am thinking to build hot wire CNC with
TB6560 4 Axis CNC Stepper Motor Driver Board Controller and there are so many different motors available on e-bay, but I kind of like this ones http://cgi.ebay.com/ws/eBayISAPI.dll...STRK:MESELX:IT
Will you recommend them?

Try HobbyCNC, thier smallest motor is more than adequatre for wire cut and half the price of the one you pointed to.

http://www.hobbycnc.com/products/stepper-motors/

Wire cut machines have very little drag on the wire if any as the wire burns away the foam and there is nothing to hold the wire. So low power motors work well with them.

Have you seen this site? http://www.alltronics.com/cgi-bin/ca...ry=55&start=20

They seem to have good prices in case Ebay doesn't have exactly what you want.....

Bought the TB6560 and everything works fine with Mach3 and the Nema23 steppers. I want to use GMFC and therefore you need a timer. Thats no problem to make.
Just need some help how to assemble this timer to the parallel cable and how the pin layout should be.
Someone experience with this combination??

i use the timer from the GMFC site

The #23-130-DS8 motor at Hobby CNC is a little more than half the price of the one your link pointed to. If you find motors that cost less then that is what I would get.
