Problems whit the switches in pncconf

Hi everyone, I have a normal CNC milling machine and it has three home switches, an emergency stop and a probe to detect the part, the card I am using is a MESA 7i96

I have tried various configurations in pncconf for the home/limit switches but it gives me an error.
Can somebody help me?

thanks you

What error ?

Hi, if i select in the tab TB3 the switch X, Y, X home when i push the Button Home All in the screen down of the left the error image missing https://i.imgur.com/O4GplYE.png

My swith is usually open, it switch off in contact with the axis

Are the home switches normally open or normally closed?

If normally closed, you need to invert the home switch inputs

Also you have the EStop pin set as an output, this is not correct

normally Open.

If I put the EStop like the switch the LinuxcNC is blocked 

How to fix it?

Thanks you so much

OK for normally open switches you don't need inversion.
The error means that when linuxCNC homing detected the home switch,
stopped and then wanted to back-off the switch, it was already open.

Can LinuxCNC overrun the closed switch position at home?
 If so, you probably need to change the home switch mechanics
or slow the home search velocity. so it cannot overrun the closed
switch position.

On a 7I96, You should not set any of the GPIO 0 through 11 to outputs
It sounds like you may need to invert the EStop input polarity
