A simulator that does not support radius compensation (like camotics) is of very little use.
And from my point of view a simulator should offer more then just showing toolpath motion.
A good simulator is topmill from mts (but its not free nor exists a linux version).
The 3D-simulation is nice to look at, but not really important.
What makes this simulator invaluable is the cut-view of the created workpiece with the unlimited variants of measurement. Geometric points snap the measuring tape and you can zoom in and out and visualize any kind of error.
The cut-plane can be moved and there are three cut planes like iso views of technical drawings.
