Home + Limit from just 1 input pin: HAL config explained

Actually, now I understand what you have done!
so simple, silly me.

I will give it some thoughts,
thanks for now.

Well, reproducing your test, I got different results
For the sake of completeness, that is what I did:
1. Loaded LinuxCNC with sim.axis config (I am away from real machine and don't have a parport available)
2. Opened HAL Configuration and typed this:And got this:
 

Have you added lut5 to a thread?

Of course not
Felling stupid.
Thanks!

Hey Guys,
Just to close this topic, I was getting LUT5 function the wrong way, in fact, what happens is that the function 0x10000 means LUT5 will output true only when IN4=TRUE, IN3=IN2=IN1=IN0=FALSE

This means that Limit switches of the joints will only be TRUE when:
1. the serial circuit of switches is open (IN4=TRUE)
2. none of the joints are in a homing operation (IN3=IN2=IN1=IN0=FALSE)

Thank you all
