Interestingly, this technology is not lost, and it is in a current vinyl cutter/plotter, the Silhouette Curio 2:

But this is quite a new model and I don't remember seeing this technology anywhere else for a long while, so perhaps they had to wait for some patent to expire?

These machines also have swappable tools (effectively a two tool changer).

I think ultimately the plotter largely became the vinyl cutter.
