I am using a proximity switch in NC mode. I do not use any resistor
(e.g. 4.7k) and it still works. Do I need a resistor for my limit
switches and what are the advantages/disadvantages with using a
resistor?
Thanks,

I'm trying to finish up my gantry router and I'm at the limit switch
part. Here's what I was thinking of doing. Take the 5v from the pc
and run it through a 4.7k resistor to a NC limitswitch and then to
the
11,12, or 13 pin on the port. Does anyone know if this will be a
problem and if there is a better setup? I thought it would be
better
to ask than to cry.
