As I've 2 lan cards (the onboard and a second PCI board), I tried to launch
ip a
when connected to both, and this is what I get:
connected to Mesa (onboard card):

joccnc@JocCnc:~$ ip a

Going by your most recent answer I interpret the above:

It appears to me you have two network configurations "Web" and "Mesa 7i76e" In both configurations you appear to have the first network port selected. This means, when you click on the "Mesa 7i76e" network, the pc tries to connect to the Mesa card via the network port that is connected to your LAN.

To fix, right-click on the network icon, click "edit connections", click on "Mesa 7i76e", click on the little gear at bottom "edit the selected connection", click on the "Device" dropdown, and select the correct device, click on "IPv4 Settings" tab, make sure the "Gateway" field is empty. click "Save", close the network edit window, and try reconnecting to both networks. On my system, I have both networks connected at the same time.

Don't change settings for the "Web" connection, from what I see, that one is likely configured correctly.

It'5 days i'm away for work, hopefully tomorrow evening i can come back to my cnc.
Anyeway, to give an answer to tommilight and nwe.
I've 2 phisical lan cards. The 1st (let say A) is the MB's onboard lan card, the 2nd (let say B ) is a separate PCI card.
A is connected directly to mesa card. B is connected to my domestic LAN (then to my router). 2 different phisical cables. This because, if I remember, mesa cards don't love to be connected via router.
Untill 2 years ago, when I worked with my cnc, I used to connect to A (I don t remember if eth0 or eth1), that case my cnc worked perfecly, but i didn't have any access to the web or to my nas.
Then, if I connected to B (in case I need to access the web or my Nas) obviusly the cnc wasn't available.
But I remember I hade 2 different networks (eth0 and eth1).
This year something happened (I didn't do anything but start the pc), so if I connect to the web, i can access internet,but if I connect to mesa (and linux tell me "you're connected to mesa 7i76e) linuxcnc gives me errors.
Now, ok i can try to setup again the network as tommylight suggests, but could it be better to phisically remove the PCI card (B )? I do not need internet or access to my nas whe I use my cnc (that pc is exclusively dedicated  to the cnc machine), I can easily use a normal usb pendrive to transfer the cnc files (I design and program my jobs on another pc),I just care about having my cnc working......


 

For step/dir, Mesa 7i96S is the right choice, and if you do need more IO add Mesa 7i84 with 32 inputs and 16 outputs and wires to 7i96S with a simple cut down LAN cable.

If need more I/O than a 7I96S can provide, a 7I76EU is a one card solution (basically a 7I96S+7I84U on one card)

You have setup 2 networks on the same 1'st physical network card, the 2'nd network card has nothing set.
WHY????
That will not work, so start new and use this:
forum.linuxcnc.org/27-driver-boards/3559...ethernet-mesa-boards

If mesaflash reported that error, update mesaflash
(instructions on the git site or above in this thread)

github.com/LinuxCNC/mesaflash

If LinuxCNC reported the issue, you need t o update LinuxCNC.

(You don't actually have to update LinuxCNC as it will work fine but will complain about the card every time you start LinuxCNC)
 

I'm having the exact same problem, has anyone figured out what's going on?

Tks

Perfect!

I swapped computers for a i5 and now it all works fine, thanks!!

It's not a laptop, it's an i3 mini PC, I'll swap it for a i5 I have laying around and see what happens.

I'm a huge fan of your videos, I was actually watching one of them when you replied!!

This PC may not be suitable. Is it a laptop? If so, replace it with a desktop.
There is no simple fix as it is a culmination of things required to tune the RT Kernel.

Hallo

Seit langen wieder eine Frage.
Meine aktuelle Eckdaten.
-Lenovo W520 
-Linuxcnc 2.9.8  auf Debian Trixi
-Mesa 7i76e

Ich habe folgendes Problem.

Meine Servo thraed schiesst  sporadisch in die Höhe und es führt zum Abbruch von Linuxcnc.

Meiner Meinung scheint der Netzwerk Controller Intel 82579LM sporadisch zu aussetzer von rund 1Sekunde.

Jetzt ein paar Fragen.

1.Welcher Treiber wird von Debian Trixi  für Netzwerk Controller Intel 82579LM benutzt?
   - e1000e ???
2. Wie soll ich folgende Abfrage "ethtool -c enp0s25" interpretieren  ?

Ausgabe:
3.Warum werden nicht alle Einstellungen angezeigt?
4.Kann man den Netzwerk Controller Intel 82579LM so einstellen, das ich die Aussetzer weg bekomme?

Ich hoffe mir kann einer von Euch was zu diesem Thema sage.

Gruß Califax


 

I'm starting a PrintNC build, as far as the control side, my setup is as follows:

• Dell Optiplex 3040 (disabled all power management, VM and internal wifi fron BIOS)
• MESA 7i76EU
• DM556Y from stepperonlineI created a new configuration in linuxCNC, and connected one of my drivers and steppers to it to make sure i was doing things correctly, I can jog the stepper from the UI, but after a few seconds I get this:hm2/hm2_7i76e.0: error finishing read!I'm new to all this so i have no idea where to even look, thanks!!

so far all works well, you did a great job thanks. for now this will do.

regards Adrian

The current firmware puts the PWMgen on P1 pin 1

If you want the PWM  on a 7I85 RS-422 output, that would
require different firmware.

thanks a lot. tomorrow i try if it works. it is getting to late. the 7i85 board is not connected yet. i first want to make all working. then i will connect the encoders on the motors and connect the 7i85 board. what pins do i use without the 7i85 board to use the pwm?
