That was my impression, but the language could be said to be fuzzy at times. Where, or how, does this fit in with the tp's version? For smooth limits, I'd assume the tp is slightly slower yet than the slowest linear axis? But I don't normally pay that much attention since it's Z (on a mill) thats generally both the slow poke AND doesn't often have that far to move.
