About 1 1/2 years ago I was told Fadal was coming out with a new controller and it was supposed to be at WESTEC this past year, so its a good thing they are finally going to release it.
I would like to see them support the NURBS G code (G62.2 ?). My cam system will output NURBS and right now roughly 90% of my work coming in is entirely NURBS surfaces. For the most part my controller (-5) works fairly good, but when the toolpaths start to contain lots of simultaneous XYZ points on steep surfaces (especially "L" shaped), the machine starts to jerk and can't keep up with the programmed feedrate.
