Problems whit the switches in pncconf

OK for normally open switches you don't need inversion.
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.

eg. the home switch MUST stay triggered all the way to the limit switch.

I don't see any mention of limit switches

My machine is small (300mm x 400mm x 55mm) and it only has three switches and I want them to be the home switches

what I have observed:
If I use normally open switches it doesn't work.

the box inv of the switches does is look for home or one side or other. does not work to set the switch open or closed

If I only put the X axis switch it works fine and it can only be normally closed, normally open it doesn't work. if i put other axis the switchs no work

I want is that there are only three switches at the start of the machine, and when I turn on the machine and press the home button, the machine will look for home and be ready to work
 

Both normally open and normally closed switches will work
You need to invert the 7I96 inputs for normally closed switches.

_But_ the error you reported seems to indicate that the (normally open)
home switches closed and then re-opened unexpectedly. This most likely
indicates a mechanical or homing setup issue.

Note that this really has nothing to do with the 7I96 or pncconf

how can i set the switches?

The switch mechanical setup must be done such that the switch
state does not change during the decceleration from home search
velocity to 0 velocity (after the switch is detected).

You may be able to solve your current problem by reducing the home
search velocity.

It's also possible that you may need to debounce the home switches,
but I would check that you are not overrunning your home switch first.
