Hey guys,

I have a 4th axis setup and I want to run a pass along the outside of the cylinder to smooth it up.

My post processor (All the ones I have tried) post the surface mill the same way... like this...

( OPERATION: FINSH)

( N1 T1 = 3FEM )

N45 G21 G17 G40 G80 G90 G94

N50 G15 H1

N55 G0 X0. Y0. Z20.0

N140 X-104.845 Z-2.02 A70.457

N145 X-104.844 A70.412

N150 X-104.829 Z-2.0 A65.837

N155 X-104.816 Z-2.022 A62.115

N160 Z-2.021 A62.07

N165 X-104.799 Z-2.001 A57.226

N170 X-104.786 Z-2.022 A53.639

N175 A53.594

N180 X-104.769 Z-2.001 A48.616

N185 X-104.756 Z-2.022 A45.028

N190 A44.983

N195 X-104.739 Z-2.001 A40.005

N205 A36.372

N210 X-104.709 Z-2.001 A31.394

N215 X-104.697 Z-2.022 A27.896

N220 Z-2.021 A27.851

N225 X-104.679 Z-2.001 A22.783

N230 X-104.668 Z-2.02 A19.599

N235 A19.555

ETC ETC. Problem is... when the code runs, either with rot rollover on, it rolls all the way around for each change in X-location, with it off, it start/stops...start/stops... SLOW AND ANNOYING.

Is there a way to make mach 3 interpret this into one smooth motion?

Thanks.
