I use SolidWorks & SolidCAM and Mach4 for my simple 2 axis lathe.
Looks like SolidCAM can not do elliptic so wonder if there is a plugin like software for Mach4 that allows one ellipse turning?

By the way, my lathe have an encoder attached to the spindle.

What you mean elliptic? Fillet? Arc?
Why not solidcam can't?
If you can upload an example to see.

You need to change your post-processor to mill-turn and your lathe need to have 3 axis. You must change the spindle motor to a servo or something to make movement than speed. Mach4 and solidworks-solidcam is capable for this, no plugin need.

I don't think the spindle needs to be a servo. The lathe in the video has an induction motor driven by a VFD. But the spindle have an encoder with hall, same as mine. He uses LinuxCNC though.

As i said you need a way to use your spindle as movement and not speed. Don't believe that worth to try with encoders e.t.c
To do something like that with encoder, you need to have a high resolution encoder not just a hal to know where exactly is the spindle. That info need to know mach4 and use is as an Axis ( A, C e.tc.) or have some kind script/plugin to use that info when you want.
If is possible, yes i believe it is, if it worth it, i think not.
The video is turn cutting with rpm sensing and the 1st video was face cutting like a mill.
Ofc someone maybe know more..

You have to treat it as a milling profile so the spindle is the A axis and that way you can sync it to the X axis, the only problem you may have is depending on the shape you may need the tool to rise and fall on the Y axis to maintain the cutting centre line so the back of the tool is not fouling the part.
