I had a look at my router setup last night while my mill was quietly getting on with another job - having been set up using Z, edge, and centre probing! It does work when you figure out the mystic incantations. The new probing screen seems to have the same features as the previous one, but all in a different place.

I'll see if I can I write down a simple guide to at least Z straight probing later today to give you a start. At least, the way I use it, you don't have to use the probe ball diameter for that. I'm assuming that that's what you need, at least for the time being?
