Cmon peeps, is my post just all wrong or is this how a 4 axis surface toolpath should look? Anything at all?

Hi Macharoons...

I would really like to see a smooth interpretation algorythm for 4th axis machining.
http://www.machsupport.com/forum/index.php/topic,27856.0.html
I posted earlier my code and have tried EVERYTHING. It's just "The way it is." However, on a Mazak/Haas/okky etc it would be a smooth wrap right around.
All i wanted to do was mill/face the outside of a cylinder!

No idea why, no idea why I'm having issues with my code, but what ever you do... make it intuitive.

Also, I love my auto tool changing doohickey with Mach3 2010, incorporate it! I'd be lost without it!

General Mach Discussion / Need help smoothing out 4th axis..

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...

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.
