Don't use the lathe module of Lazycam since the tooling was never completed / dosen't work right.
Lazyturn is free, has a manual, and will do outside profiles quite easily. It was created to replace the turn module in LazyCam.
I use Dolphin Lathe. Price for a hobby version is around $400.
Someone posted a lathe program called EZILATHE which you may want to check out, it's free. I have not taken the time to
test the generated code.
You may want to look into BobCad, as that has lathe capability. Think Hood uses it and may reply to this thread.
