The pin for the inverted state would be 'hm2_7i76e.0.7i76.0.0.input-29-not'

Try and use the pin 'hm2_7i76e.0.7i76.0.0.input-29' in your hal instead of 'hm2_7i76e.0.gpio.029.in_not'

Using LINIXCNC 2.9.2 on Debian 12 in combination with a Mesa card 7i76e. Both limit switches of each ache are setup in parallel (LJ12A3-4-Z/BX  like NPN) with a pull-up resistor of 100k ohm. My Aches are attached to mesa digital in X => 27, Y => 28, Z => 29. The signal has to be inverted because is up if the limit switch is not used. So far so good. Now configuring my LINIXCNC to have a shared both limit and home together.net both-home-z     <=  hm2_7i76e.0.gpio.029.in_not
net both-home-z     =>  joint.2.home-sw-in
net both-home-z     =>  joint.2.neg-lim-sw-in
net both-home-z     =>  joint.2.pos-lim-sw-in
 The INI contains this settings for the Z-archesHOME_OFFSET = 0.0
HOME_SEARCH_VEL = 2.000000
HOME_LATCH_VEL = 0.500000
HOME_FINAL_VEL = 0.000000
HOME_USE_INDEX = NO
HOME_IGNORE_LIMITS = YES
HOME_IS_SHARED = YES
HOME_SEQUENCE = 1
 Now to the issue, if I home the machine the limit switches get ignored. This applied to all aches. To simplify the troubleshooting I focus on Z-aches only. If I use a piece of metal and hold it in front of the limit switch the mesa digital in 29 acts as expected, but not the chained signals.

Any advice are welcome.

DAMN!!!!
That is 99 degree C all cores all the time, no wonder the PC is giving up it's ghosts, slowly and painfully!
The good thing is, you have it easy to remove the CPU cooler and clean both the CPU and cooler, then find some thermal paste and apply some to the CPU and mount the cooler back.
Tooth paste works instead of thermal paste, albeit for a day or two only.

sensors at the time of error:
 
Also this is how I have my pc mounted with plexiglass. Should I holesaw a vent for it through the plexiglass? 

Other things to check:

1. Do you have an Intel or Realtek Ethernet chip?
( there are chip specific things you can do to improve latency)

lshw -class network

Will list your Ethernet (and wireless) network hardware if you are not sure

2. Have you run a simple ping test like:

ping -i .2 -c 4 10.10.10.10
sudo chrt 99 ping -i .001 -q 10.10.10.10

(use 192.168.1.121 instead of 10.10.10.10 if your 7I76E is set for that IP address)

The first command populates the ARP cache so the ARP lookup doesn't add time to the first ping
The second command should be run for a few minutes (and then stopped with a control C)
and the results posted here.
 

open a terminal and type
sensors
see what temperature the CPU is at while LinuxCNC is running, anything above 60 degree C should be mitigated by re-pasting the cooler or replacing the fan or with better cooling.
Some processors will handle over 90 degree, some Intel Xeons will throttle badly at 63 degree only!

I am still getting the same error even after disabling these. Is there anything that can be done further maybe give the computer more margin for error if thats possible?

Thanks gentlemen for the bump and the bit file!

Sorry didn't notice

 
 

Bump as it seems it has been missed.

Versuchs mal so:

Ich nehme an dass Joint 1 der Y Achse zugeordnet ist.
Der Signalname 'limit-home-y' ist frei gewählt.

Hallo zusammen!

Ich hab mal wieder eine Anfängerfrage:
Wie gehe ich bei den Verknüpfungen vor, wenn ich auf einer Achse nur einen Switch habe, der auf der einen Seite als gemeinsamer Home/Limit Switch funktioniert, auf der anderen Seite aber als Limit Switch für den Endanschlag fungieren soll?
Auf der Home/Limit Seite ist mir das klar, da ist das Manual ja eindeutig. Nur - da ist auf der gegenüberliegenden Seite ist ein zweiter  Schalter gezeigt, bei mir fährt der einzige Schalter für die Portalachse auf der Z-Achse mit, also nur ein Switch.
DIe Verknüpfung bisher sieht so aus:# --- MIN-HOME-Y ---net min-home-y <= hm2_7i76e.0.7i76.0.0.input-06
Kann ich den gleichen Eingang jetzt als max-Y definieren? (offenbar nicht, da gibts die Fehlermeldung "...hm2_7i76e.0.7i76.0.0.input-06' was already linked to signal 'min-home-y'")

Danke für Eure  Antwort dazu!

You need to disable turbo boost, C states > C1 and speed-step

All power management is disabled in BIOS but I do have Intel turbo boost, C states, and Intel speedstep enabled. Here is the halcmd show param info 

and here is the hardware clockspeed info
