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.

I did not try another LAN cable.
The machine and PC are grounded properly.
I dont have a DVM at the moment but as soon as I get one I will measure those.
I believe this is a software issue because even with qtplasmac not running I get the disconnected error every 45 seconds

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