Fusion does offer FEA and other simulation types.

You can buy very accurate electronic tool setters for ~$100 on ebay. Cheaper and better than the Tormach height gauge system and way cheaper than the Tormach ETS. The Hallmark ITTP is also far better...

It's also worth noting the Skyfire CNCs come (optionally) with a 5-axis controller.

There's no driver or connection available in the electrical cabinet for a 5th axis, so as far as I'm aware nobody has done it.
