Key Takeaway:
Since it’s conventional cut, Ensure both halves of the tip is fully cut immediately in one continuous swoop; do not allow the cut to start half way through it (i.e. parachute in at the tip itself), cut half of it, and then do the other half later because it will be unsupported in the conventional cut (which is spinning outward away from the material core and will yeet the entire taper knife edge into mount doom as a chip because theres only a knife-edge slither of material left which can’t take the strain and is weaker than the force to cleave the chip away clean - so it all comes away instead.
Positioning literally anywhere else except for right on the tip node of the corner to enter/exit the cut solves for this; even if its literally just before the corner - just don’t divide the corner into 2 halves by entering right at the tip. Also, less critical but potentially reduces chances of chipout further by providing the option to swapping to climb-cutting but I haven’t verified this - certainly theoretically sounds like it might help be more forgiving but would require testing

Proposed:
C3D - please seriously consider this feature request applied to both the ‘advanced vcarve - endmill and vbit’ toolpaths to promote the green scenario. It would paradigm change the performance of your advanced vcarves for Facegrain (and by extension, endgrain). I have used your advanced vcarve toolpath extensively so I wouldn’t bring this up if I didn’t feel this is worth your time to improve the competitive edge of your product.
