Adaptive milling on lathe gives wrong nc-code

[gvisserVMT]

I try to mill a pocket using live tooling on a lathe. (see attachment)

Now the main spindle turns and x-as moves very slow.

I want the main spindle to be stationary and the x and y axes to move

Can someone tell me how to program it right?

What is your machine and post processor? Some machines don't really like going below centerline in XY milling (Haas, as an example), so the post prevents that from happening. Other machines and posts, Doosan, for example, permit you to input a minimum negative X value. For my Lynx, that number (to be safe) is around -25mm.
