I personally would go with this type https://www.ebay.co.uk/i/22256467184...4960578&crdt=0

No moving parts to go wrong.

To tell the truth Ive bought that kind for my home switches, was thinking about going mechanical for my limits because of all the forum threads I have seen about connecting proximity switches and different types (npn, pnp) and the problems people have in connecting them. I guess its not complicated and if I get confused I could always get my multimeter and figure out whats going on.
But I just dont want anything more complications right now :)

Yes you are correct they don't need to be accurate for limits and easier to connect in one loop.

Am I right in thinking it's pointless to use limit switches if you're only going to wire them to the Estop as the home switches can do the same job? They become useful when fitted to an external override like a latched relay?

Is this correct?

You are thinking of wireing them to the estop input on the bob only?

at moment yes I have crashed into the side of my machine already lol it's doesn't do a lot just fires a stall protect didn't meant to was see how close I needed to get to the microswitches. Something like Thor you got big issues but with 2nm and AM882's it seems a non issue.

since all my switches with wired NC if the machine fails to stop machines probably crashed and stuck in a loop which is probably extremely rare in linuxcnc.

I know lots of people trust bob inputs and software and do similar installations like you are planning. It was this forum that made me question this and think more industrial ;)
But almost all of the time your way will work haha
