Why isn't the actual slanted path shown in lcnc's axis interface?

  I used the bridgeMill routine of the axis interface to simulate that the milling machine path is different from the z-axis path in axis. The cutter path of analog milling machine is inclined, axis is vertical, why is this?

The pink lines on the left show the actual tool tip positions recorded as gcode is executed (this includes all the calculations that happen in the custom kinematic)
The white lines on the right show the preview which is created from a dummy run of the gcode by the interpreter when the gcode is loaded. This interpreter has no knowledge of any custom kinematic and lives in trivial kinematics only.

But I saw a video on youtube, and run the same routine, and it was completely normal, which is confusing.Here's the youyube link:https://youtu.be/65Wd6ZGoWys?si=MS6gWgkNu8SoDB1t

Apologies, I forgot:

For this you need to change this line in the [DISPLAY] section in the file '5axis.ini'
From this:
GEOMETRY = XYZCBW

To this:
GEOMETRY = XYZ!C!BW

Thank you.

Thank you so much for showing the axis of rotation correctly in the interface.

I am sorry to send a duplicate post, I tried various methods also did not find how to delete, thank you for your help.
