3rd cut side A, .3 deep. Etc. Alternating side to the bottom of wall.

Also try smoothing at .001".
Good to know. I'll put that in my notes and use it the next time I have a thin wall project.

I did some reading on the Autodesk Forum about tolerance and smoothing. What I got out of it is the combination of the two should equal your machine tolerance holding capabilty. Then adjust the tolerance to smoothing ratio from 1/1 to 4/1. The focus of the subject post was to minimize file size and decrease generation time. Nothing was mentioned about improving surface finish. All this being said I have to start somewhere so I'll use .001" for smoothing and tolerance and see what that does and adjust from there. I've got a couple of mods going on with the mill, Y axis bellows cover and Z axis lubrication pump, then will get back to it.
