For some reason my ellipse shapes are being milled with a slight hesitation between each line of code.  I have the constant velocity checked.  I have imported a dfx from Autocad into Bobad to generate code.  The ellipse in Bobcad is broken into segments and not a continuous line.  Not sure how to correct this.  Thought the constant velocity being generated in Mach3 would take care of this...any ideas out there!

M3 can only do circular or helical interpolation on move like G02 i think, not elliptical. If your CAM generates curves as small straight segments using G01 M3 can't I believe link them together.
