1 question from me is that,. If I have a NO estop I'll need NO limit switches yes? Or does it not matter if estop is NO and limits are NC?

I plan on getting an ess in the future and use one board running axis/spindle and one board running estop/limits.
You think it works well because you have nothing to compare it against.! When you get the new controller with higher pulse freq etc you'll see the difference.

Regards the N/O question then provided you use separate inputs then you can use different switch types. Obviously if wiring in series and sharing the same input they must all be the same type.

Also if your thinking to buy Warp9 ESS then I'd look at others like UC300 because they are better than ESS and you are not stuck with mach3/4.
