Ethernet connection to Mesa 7i76e disconnecting on its own after one minute was created by RMJ fabrication
I ran pnconf wizard and made a configuration for my CNC plasma table. I am able to home and jog my machine for about a minute until I get this error.
It seems like the ethernet connection is disconnecting on its own somehow. Any ideas on how I could get the ethernet to stay connected so I can use my machine.

Is this possibly Plasma/EMI related?
That is, do you still get communication loss when the Plasma source is off?

I don’t think it is Plasma/EMI related. My plasma cutter was not connected or turned on.

What does:
sudo chrt 99 ping -i .001 -q -c 60000 [card_ip_address]
report? (it will run 1 minute then print statistics)
[card_ip_address] is either 10.10.10.10 or 192.168.1.121 depending on 7I76e jumpering

Did you try another LAN cable?
Is the machine and the PC grounded properly?
Use a DVM and measure between Mesa 24V GND and machine case, in AC mode, while the machine is ON, post result.

Can you power off the machine and leave only Mesa powered?
