Limit&Home at one pin

Hello,
I'm trying to configure LinuxCNC (3axis) to work with limit and home switches connected to one pin, but when I press 'home all' button, Machine move to Limit switch and show message 'Limit error'. I think software should know in homing cycle not use limit switches. When I connect all home sw to one pin and all limit sw to the other pin everything works fine. Is there anything else in .ini file I should turn on? Please help.

please post your hal and ini files as attachments

I attach the files, this is modification of example mp1000 plasma machine. When it start homming and machine trigger the Z limit switch I got error for joint 0 and 1 limit switch.

Thank You for reply, unfortunatelly didn't help:( I got the same errors. Maybe it's impossible to do that, in stepconfig input setup there isn't an option to gather all limit and home? I attach files after changes and errors screenshot.

Limit errors appears in the same time switch is closed in homing cycle (switches are normally open). I will try to check how it works in case of homing first axis only.

you can actually have all the switches on one pin , and use limit switch as home etc , linuxcnc is very flexable . check to see what state your switches are in hal configuration
you may need to invert the logic of the input , you would be better to have closed switches and wire them in series .

by your hal file you showing the limit switches unused
#net all-lim <= parport.0.pin-10-in-not
#net all-lim => axis.0.neg-lim-sw-in axis.0.pos-lim-sw-in
#net all-lim => axis.1.neg-lim-sw-in axis.1.pos-lim-sw-in
#net all-lim => axis.2.neg-lim-sw-in axis.2.pos-lim-sw-in
and the input pin inverted ,

are you trying to wire these in parallel ?

check what linuxcnc says the state of the switch is and go from there , do you need the input inverted ? etc

Yes, actually I have connected all switches to one pin, switches are connected parallel. Probably I was trying reverse limit input by negation, but after modification .ini file I will try one more time. Limit switches are use in hal together with home like below, net is called home but there are both function there:

net all-home <= parport.0.pin-13-in-not
net all-home => axis.0.home-sw-in axis.0.neg-lim-sw-in
net all-home => axis.1.home-sw-in axis.1.neg-lim-sw-in
net all-home => axis.2.home-sw-in axis.2.neg-lim-sw-in
