now that the ribbon cable is correctly polarized, I have simulated running the machine three times for a longer period of time.
Started the machine and simulated the axes. I then let the machine stand still to see what happens.
The following three errors occurred after each start and referencing of the machine, each time between 10-25 minutes.

The error is because of excessive network latency
There are a couple steps that can improve this,
but some background information is required.

1. What computer hardware are you using

2. What is the result of the command
cat /proc/cmdline

3, What is the result of the commands:

ping -i .2 -c 4 10.10.10.10
sudo chrt 99 ping -i .001 -q 10.10.10.10
(wait a couple of minutes after the last command and then hit control C)

4. Do you have all power management options disabled in the BIOS?
are hyperthreading, AMT (if present) disabled?

... some background information is required.
I learn with background information and it's always good for my brain ;o)

1. what computer hardware are you using?
We have already discussed the hardware in great detail in this thread.
Please see my post ...
forum.linuxcnc.org/39-pncconf/52373-pncc...7i76?start=30#298972
... Of course, Debian/LinuxCNC is now installed instead of Linux Mint.

2. what is the result of the command
cat /proc/cmdline

The result is ...
cnc@cnc:~$ cat /proc/cmdline

3. what is the result of the following commands?
ping -i .2 -c 4 10.10.10.10

4. have you disabled all power management options in the BIOS?
Are Hyperthreading and AMT (if available) disabled?

I can't really answer that as this topic has not been dealt with further in the thread either. We got stuck on the disassembly of the PC at the time.
I disassembled the Barbone PC, applied new thermal paste and made modifications that significantly improved the cooling. After that, the issue remained unaddressed. As I don't know the terms and the effects in the BIOS, I don't screw around without the support of cracks ;o)

That 13.566 is really bad, but no idea why and what is causing it.
Did you try to use a USB-LAN adapter?

Edit, removed info about power supply as it is not relevant to this case.

Sorry for maybe repeating stuff, but we read everything on this forum, so it is hard to keep exact track of info.

Repeating a post from a month ago:

The 13 ms ping delay is not caused by a power issue (the 7I92 cannot
restart in 13 ms, if it loses power it will take about 1 second to recover),
The delay is most likely caused by some power management running on the host PC.
If this cannot be discovered and changed on the host PC it may be that that
PC is not suitable for real time use.

Ooohh i had that thought on the back of my mind when typing that, just was not sure, hence the sorry there as i was certain i am missing something.

Yes, I connected the USB Ethernet adapter between the PC and Mesa until the beginning of this week - but in the last few weeks there have been repeated disconnections, first with the Internet, but then also with the Mesa card. So the card no longer responded to the ping. After shutting down and restarting the PC, the connections were restored after a few minutes.

But in this case I have to connect the adapter again and do the same tests as PCW suggested, maybe it will give a better result?

You recommended a Maxwell 5V power supply at the beginning of the thread and I wrote to you that I was already using one which I think delivers 5.06V. I understood your feedback to mean that this is ok?
forum.linuxcnc.org/39-pncconf/52373-pncc...7i76?start=20#298909
Well, I mean the current one is new and if I had to get another one I would buy the same Maxwell again, purely because of the space available. But what does the power supply unit have to do with the 13,566?

Hey, no problem - I wanted to save myself some time and saw my comment as the shortest possible answer. Please don't take it personally, sorry ?
This should not be understood as a reproach. I can only begin to imagine what you do with your support for LinuxCNC, to which I am deeply indebted.
I have also decided that when my machine is running and I return to my usual working environment (CAD/CAM/FEA), I will donate to you who live for Linux ;o)

Are you saying that you are using a USB --> Ethernet adapter to connect to the 7I92?
if so, this is not likely to work.

Normally you would connect the 7I92 to the motherboard Ethernet port
and if needed, use a USB --> Ethernet adapter for internet access
