Engrave is a Pro only toolpath option — we’ll need to update that in the instructions.
If you use the Carbide 3D (Nomad) license in MeshCAM it will take care of feeds and speeds for any materials which it has support for.
As noted, the new Carbide Create has updated tool libraries and feeds and speeds — pretty much all the tooling Carbide 3D sells should be in it, and the descriptions are general, and one can use the feeds and speeds for similar materials — for instance, use Softwood if you’re cutting MDF.
