General Mach Discussion / Re: wiring diagram for limit switches
« on: June 15, 2008, 09:22:58 PM »Dont really need a wiring diagram, all you need are normally closed switches and run them all in series, ie have a wire from an Input pin of the parallel port(or breakout board) run this to one wire of first switch, other wire of first switch goes to one wire on second switch, other wire on second goes to third switch and so on until all your switches are connected then the last wire goes to a ground on your port (or breakout)
Doing it that way will mean you only use one pin of the parallel port for all limits and Home switches. If you prefer to have each axis seperate then you can wire all the switches on each axis in series and use one Input pin for each axis.

What about pullup resistors?
