Thanks for all the info. Gerrys screenset seems the way to go for me. Are you able to use say pin 1 and have all your limit switches wired in series and home switches to use pin 2 and also wired in series? This will leave pin 3 for touch plate? Not sure if this makes sense so please correct me if it doesnt.
I also forgot to mention i have 5 proximity switches on order so i will have to wire all 5 into my router. I have found some connections to use which both come in 4 pole and 8 pole. Any idea which ones are normally used for proximity switches?
Thanks
