Make a new back taking top plane and rotating it around the X Axis. The default back is wrong for lathe on the screen, but most time will post good code. In your case sounds like you need a correct back. I will normally make a correct back and correct bottom plane from the start and use them verses the default back and bottom because of this very issue. 

I just tried it. Both duplicating the top, front and back plane then rotating them. But it still only post when X axis is in the wrong direction. I manually replaces all negative Z and Y numbers with positives after posting it this time. But I still need to solve this

I have a similar problem. But I can only get it to post if I choose BACK. But choosing BACK flips the Z axle around, negative numbers become positive and the other way around. For the lathe operations I have wcs Top and Tplane: lathe upper left.
