The path has is a quite subdivided. Possibly the bug is caused by some "bad" node which can have small tangetns. Try to make all segments straight before applying Engraving.
To do that - go to edit nodes tool (F2), select all nodes (Ctrl+A) and make all segments straight - by pressing the button in the toolbar.
Use the Console, Luke.

Yes i have subdivide the path because if i set some simple node the engraving done segment where curve would be done...
I have ever try make straight all segment but same errors and many others done.

Here another try with less node but you see many artifact, bad path and the deformation of the letter !

hmmmm.... i'm not sure... but this may be a bug with simulation software, or with tools definition (wrong angle at the shape definition).
It would be great if you will be able to do the actual cut and see will this bug occur or not.
Use the Console, Luke.
