Per,
Limit switches (NC) should be wired in series to the estop relay. If
you pass that information back to the PC thats one I/O. If you hit a
limit it should be obvious which one it is. On home switches (NO) I
have mine wired in parallel and home one axis at a time, Z, then Y
then X. Another I/O. A singe port should be fine without spindle
control. How to do spindle control is entirely dependent on which
hardware you select. A PLC may be the best answer for that.
