Earthing?

[Edward]

Thank you, Neil, I'm with you. Though in my head I am initially thinking that it may not be so easy to implement on a vertical mill, say, the X axis, sensor somewhere in the middle, hitting targets at either extreme...
I can see the opposite working, i.e. sensor stationary in the middle and triggers at the extreme ends moving.

Neil answered for me but no difference if sensor moves or Target moves. Infact it's common on mills for the Switch to be stationery and the targets or Ramps if mechaincal type Switch to move with table or saddle. See pic.

You do whatever seems best to you, you cannot actually go far wrong. Don't worry about me an Jazz, I like winding him up and he likes screaming obscenities at his computer, it's a match made in heaven, no lasting damage has been done.

Robin you don't whind me up and believe it or not don't curse you to the PC, like you it wouldn't listen.! . . . You do Piss me off with the one line sarcastic unhelpful replys and excrament which comes from your fingers.

However much as I'd like to go at it with you decided In the interest of not hi-jacking (more) Edwards thread and fact can't be arsed after long day I'm not going to endulge your delusion of whinding me up by replying to your challenge regards Screening and Metal enclosures.

Anyone who want's to follow your Stupid approach is very welcome to go for it.!! . . . . They will soon see who was correct.

Thank you, Dean. The picture says it all. Not only do you save on wiring, but you save on sensors too! I think I will implement something like this.
