One other thing you need to consider . Youneed to do your math model where it is self supporting as to being able to run without outside references such as reading a dro for position correction.

It is NOT that mach cannot do it BUT to do it that way you will have to run the entire GCODE side from inside the macro as well AND MachVB with Gcode running inside do not always play well together at this time.(;-)

THe gcode side has ALL the math functions you should need.(;-)

Just a thought, (;-) TP

YOu should be able to develope a math model to do your shape in the 2 basic planes ZX and ZY so your parabola will be accurate

Cheers. I had a re-think about this and I'm working on a different approach to cutting parabolas. The algebra is rather involved though, and I haven't had a lot of time to sit and think seriously about it. I'm taking over a factory and setting up some seriously hefty gear in there next week ... I'll get back to this when I can.
