Thanks for the help John,
the pin??-in-not works great!
The typo is located in my computer in
emc2/configs/stepper/standard_pinout.hal. Also, the user manual chapter
4.3.1 is infested with the same typos. There are several lines near the
bottom of the page with the parport number missing. I have changed the
pin numbers and fixed most of them and I don't remember exactly which
lines need fixing.
Is there any way to link more than one axis limit pin to one parport pin
and not fault the other axis while homing? One obvious solution to me is
a physical switch to turn off the limit switches during homing. Easily
doable... But not so elegant!
Thank for the help,
Clint

instead of:
linksp some-signal parport.0.pin-??-in
use:
linksp some-signal parport.0.pin-??-in-not

You found a typo in the sample config. It should be:
parport.0.pin-11-in
That means pin 11 of the first parallel port. If you had two ports you
would access the other one with parport.1.pin-whatever
Exactly what file did you find that in? I just tried to find it to fix
it, and I can't....
