Thank you so much.

Result:
A12 Servo driver alarm has vanished.
I could "ServoOn", "Jog move". without any error in Servo Driver LED.

Buf I got this  message "Failed to get reference clock time: Input / Output error"  many times. (screenshot)

I attached dmesg log.

But you see automata's posts here? Do not be surprised if it still does not work.
Thankfully, automata has kindly posted the solution here.
Please report back how it goes and if there are problems with lcec
I hope automata will guide you to use his solution.
 

Thanks, I will report back as much as I can for a while.  ( I'm borrowing Yaskawa-Sigma-X motors for just a few weeks)

But I'm not familier about EtherCAT master, I'm not sure what to do next, so please guide me, everyone 

And I'd like to summerize procedures what I have done with your great help to get Yaskawa worked with LinuxCNC for those who are not so familier with EtherCAT master in detail like me.

 

A couple years ago I bought two BOBs and never did anything with them. Just now dug them out for a closer look. So I have two different BOBs, both look different from yours. It seems to me, if your BOB had a ground screw that had direct connection to the metal shell of the parallel cable, that would be a prime location to connect the shields of any cables connected to the BOB. That is what I am referring to as frame ground.

You are not running as root are you?

is this a normal Linux installation?

What does

report?

This is a fresh installation from LinuxCNC website.
But I downloaded  www.linuxcnc.org/iso/linuxcnc_2.9.7-amd64.hybrid.iso instead of provided  www.linuxcnc.org/iso/linuxcnc_2.9.4-amd64.hybrid.iso  by replacing 4 with 7 in the URL.

I am NOT running as root, because other commands require sudo.

Connecting all grounds to the buss bar sounds great.

One way to track down redundant grounds is to disconnect the known grounds then take an ohm reading to find out whether it is still connected to ground via an unexpected route.

Like I said, you can cheat some. I am not real strict on my projects about having no redundant grounds, but it is one of the things I work on if there are interference problems.

In your case, I would suggest concentrating on the shield grounds right at the BOB as that seems to be a pain point what with it acting up as soon as you so much as connect stepper signals and start the vfd.

Please, did you try moving those AC wires that are parallel to the BOB and within inches of it?

thank you for testing. i have been getting a very different result but will go back and see if it was something i was doing wrong.

No warnings without sudo.

I was just working on a mdi command, so it was easy to have a look at this in FlexGui.
Starting with  G0G55X0Y0

 

Then pressing the button with MDI command

 

and it goes to    G0G54X0Y0

 


the subroutine:

o<work_zero> sub
G90 G54 G0 X0 Y0
o<work_zero> endsub [1]

Here is a piece of code from mesaflash:

Hello all! I'm new here on the forum, I've been searching for a day or so now and can't really seem to figure this out. I've been using the machine with a rpi4, with the 7c81 running the 5abobx2 bitfile setup for a little while now and decided to expand with the 7i73. From what I've read, when using pncconf I should see the 7i73 or at least a way to set pins on the smart serial interface, right? So far, it never seems to show up. I have it connected to the 7c81 via a cat6 cable, and I have a power light on the 7i73. I've set the jumpers on the 7i73 to all the default locations (terminated serial, no lcd, no keypad). when using mesaflash to check the config of the 7c81, I can see the smart serial interface. I feel like there's something very simple I'm missing. I hope this isn't a repeat question, I couldn't find it here. I appreciate any help you can offer

Wow, that's a lot to take in. I may have a ground loop to the machine frame. There is a ground wire in the spindle cable that is grounded to the motor frame, which is in contact with the rest of the mill. But I also do have a ground wire on the frame going to the ground bus in the breaker box. I will remove that.

There is continuity from the BOB end of the parallel cable to the PC when the PC power is disconnected, so it probably is shielded.

I currently have all the grounds and shielding grounds running to the ground bus in the breaker box. Are you saying this is causing issues? What would be the BOB's frame ground?

I have most of the electronics mounted to a piece of sheet metal, which is connected to main ground by the green/yellow terminal block by the contactor. Should I not do this?

Do get a warning when not using sudo?

If not, something really basic is broken here.

You need root privileges (or setuid root) to access PCI hardware

What version of mesaflash do you have?

@Mark

Andys Marcos are great, but i think its something different. you only can do one task at a time as far as i know, right?

@aDm1N
You said in your last post "as far as I know, LinuxCNC doesn’t really offer something like this out of the box." That confuses me, because I already wrote about NativeCAM on the previous page. You didn’t respond to it specifically, but I simply assumed that you were already familiar with it. It’s possible that you overlooked it or that you just don’t like the tool. both are perfectly fine. However, if you simply missed it:NativeCAM does exactly what SIEMENS ShopTurn does. You write your program directly on the machine, editable and with a preview.The only thing is that the contour function was never fully completed back then and would need to be added by someone who can program. It’s called “Polyline” and already exists in milling, where it works perfectly. It just hasn’t been implemented for turning yet:

I just tried with and without sudo, I also tried while LinuxCNC is running.
Result is the same all the time:
