So, if you have G42 in force (tool on right), then you can only make left turns. Any turn to the right would make a concave (inside) corner, and would not be sharp, it would necessarily have the radius of the cutter. If you want to make inside corners, you need to blend the straight segments into an arc move with a radius greater than the cutter's radius.
A smaller end mill will not fix it if the diameter is even slightly greater than zero, if you try to make inside corners with straight lines only.
