If you have any backlash in there, it will show in this manner too.
I use Mach mill for my lathe because I have the tailstock motorized for drilling.
I have just bought Dolphin Turn and will be using it on my new lathe build.
What I do for my code on the 7-12 that I cnc'ed is to do most of it by hand. I use a standard peck drill cycle from Sheetcam for the tailstock. Always the same one. Then I just use the teach Wizard. This got me my first code and I was then able to just write the code myself after a short time. All very simple parts though.
I use the backlash in every move. I had to program that in. Move positive direction before I move into the part.
My parts are more accurate now. This is not coded for the actual distance it travels now though. It is all done by trial and error and editing the code in Mach until I have exactly what size parts I need.
This is why I bought Dolphin for the new lathe. I expect to have near 0 backlash on it.
