wedm con ejes xyuv

hola a todos quiero poner linuxcnc en una cortadora de hilo de molibdeno de 4 ejes xyuv, hay un modo de hilo caliente  pero el problema que tengo es que los ejes uv estan montados al marco o sea se mueve la mesa para x e y  pero  el problema es cuando quero usar los 4 ejes no se como deberia configurar los ejes uv ya que si quisiera hacer un cono los ejes uv deberian moverse solo en la diferencia entre X y U  y entre Y e V. muchas gracias a todos.

hello tommylight thanks for answering, the configuration for foam does not work for me, I have a 4-axis commercial wire machine in this the table moves. the axes U and Y are mounted on the bridge, so when I make figures in 2d it works, the problem is when I make 3d in axis it is configured for 2d that they move together X, u and Y, v but in the machine I have for 2d it only needs to move in X and Y so u and v don't have to move

hello andypugh thanks for answering, of course it is difficult to explain in this machine the table moves like in a milling machine and the u and y axes are assembled in the z head for explaining it in some way and what I should do I think that the u and y axes should move by themselves in difference between x and u and between y and v but I really don't know how to do this

I have a similar wedm machine that I started retrofitting but have not got to the point where I started playing with the u and v axes.

Basically, the u and v axes move relative to the bottom wire guide and that determines the angle between the wire and the xy plane. The angle is also affected by the distance between the upper and lower wire guides.

I think it would help to know how these machines were programmed originally.

For example, if you want to produce a cone shaped hole that is say 20mm in the bottom and 30mm Dia at the top, and the guides touch the work surfaces (not possible, but just to make the point) ....then the gcode would be something like this

Starting at x10 y0 and u5 v0
G3 i-15. (For xy)
But the u and v axis should then follow a similar circular path, but with a radius of 5. And I don't think it is possible to program that in one line,which I believe is the problem described above.

Maybe there is a simpler way?

BTW. How are you dealing with the spark generator?
