Mcam9 Lathe setup for new machine

[whelzorn]

I'm very new to the lathe part of mastercam, and I have a machine I retrofitted here, but the default setup in mastercam was not meant for a lathe with the tool coming in from the front of the machine (like most non-CNC lathes), instead it makes the tool paths for a machine that has the tool on the back side. How can I change it so that mastercam accounts for this?
Thanks!

EDIT: Well, I got that set I think, but now I have run into another problem; I cannot figure out how to make the toolpaths go inward, toward the center of the workpiece. The piece can start off rounded (imagine a chess pawn) but when it gets to the middle of the 'ball' it just goes straight, instead of going back in toward the center, so I end up with a rod with a rounded tip, not a pawn. I have no idea how to do this. Anyone?

I'm assuming that the Z keeps going minus without the X changing. If so try the "plunge parameters" on the rough and finish parameters pages.
Let me know if that's not what you want

Is this a lower turret setup or upper?
But sounds like the decond thoght is as Mark stated look in to the Plunge controls to let it plunge in eather both axis or just one.

Yep, that was it. The plunge parameters were set to skip over any gaps on the x-axis for some reason. Thanks for the help!

I don't know anything about Mastercam Lathe, just Lathes. (Trying to learn though) Try a 35 degree tool that looks like a point or a "V". You will be able to make most of the Sphere with this type of tool. You will need a 80 degree Front and a 35 Degree Back turning tools as well for this type of part. MC is only doing that tool path to avoid a tool collision with the work.
