I should be ok with the linux bit as the stepconf wizard is nice and easy when setting up the parallel port pin id's. However if I'm wiring X+, Y+ and Z- in series then what option would I choose for that input?

The switches I'm using a only basic, in fact they probably aren't the best for my machine as they aren't lever type ones, just a small plunger. But they are all I could get my hands on for free!

The images show the limits mounted in x and y, I haven't yet mounted the z as I need to make a suitable bracket first.
Ok I would not use a limit switch on Z- just the home switch z+ at the top because there generally is no defined position because of tool length etc.
Also be aware that if you do it in stepconfig and then edit the .ini file the file will be overwritten the next time you use stepconfig. hope this helps.
