Hello friend
You can use Glade 3.8.6 software and edit the file responsible for the image in LinuxCNC

 

OK, thank you!

What is the shorting of pins supposed to do?
I have tried both suggestions, but the command still results in the same error.

I don´t have a rpi4.
I am a bit sad about this, i don´t want to buy a rpi4 just for flashing.
Stupidly i thought this would be a good Mesa card choice for me, i now wish i had bought something with ethernet. Then i wouldn't be stuck with rpi.

Hello friend
You can use an oscilloscope on the pulse output of this board, use the test axis feature in the image below

 

I recommend leaving the drives activated at this point, as remote activation may not be enabled in this test.
I also recommend not using the board indicated in your link, as it is not reliable, it does not have electrical isolation, and when the system loads it activates the outputs by itself, making the machine move before the releases and safety.
I recommend using the 7i96s electronic board, which is very safe and high quality.

I put in the MAC-address for the new adapter into /etc/ethercat.conf, and restarted ethercat service.
There were no initial datagram UNMATCHED messages, so I use the plasma table for some minutes.
Even after a day there were no datagram UNMATCHED messages, so I call that a win.
I even went back from isolcpus=1,2,3 to no isolpcus, it works just fine without that.

 
 

The verdict is: it works.
The stiff cable is a problem. And overall making a nice package of this will be a challenge.

My first experiment was to add an M.2 to PCIE adapter, and put in an Intel I210 card I have.Here is what that looks like 

There is the small M.2 card that goes in the slot and then there is the rather stiff cable that connects to the PCIE slot. And I plugged in the I210 there.

The biggest problem with this setup is that relatively stiff cable. It runs right over the screw that secures the M.2 board in place. I had to bend the cable, it is quite stiff. The cable became sandwiched between the adapter board and the M.2 system disk that sits on top. I got it there in the end but not ideal. 
 

As for the function - brilliant! After startup, the I210 showed up as a PCIE network adapter, it showed up in the interfaces list. I did nothing, just started the mini-PC. 

Hello Mr. PCW, I would like to thank you very much for all the help I have received here on the forum. I am very happy with the quality of the Mesa boards and the countless possibilities for any type of project. Exceeding all expectations. I would like to thank the Mesa manufacturer team for all their support. I wish you much peace, health and prosperity.

My project has been completed and I can't wait to continue new projects using your technology.
I am very pleased to recommend this technology to everyone.
See you soon.

I didn't say I'd used it.

Okay, okay, I did! It's definitely more useful for looking at small sections of the HAL.
The whole thing is a little too much for the tool, but if there's a subset that you're trying to understand better, it's definitely useful.

Thanks for writing it -- I found it because I was setting out to do the exact same thing, also using graphviz, but decided I should look around to see what was already available. You saved me a bunch of work!

For some time I have been setting up a plasma system using a N100 mini-PC and ethercat drives 3xECT60 and one of my own Metalmusing EaserCAT-7000 board for IO and torch height. It is working fine, but there is the occasional, sometimes more than occasional message in dmesg/journal, datagrams UNMATCHED

In this case it is not a catastrophe, the ethercat cards easily recovers.
It means that the EtherCAT server sends out a packet and expects a packet back. For some reason it doesn't come back in time (I think).

So the focus is on this mini-PC, a T8 Firebat pro plus. It has two network ports, both Realtek. It is small, draw around 10 W, three HDMI and three USB 3 ports. Had the network worker better it would have been good, but no.
 
The network ports areI have of course tested with the realtek dkms driver, and added boot options. It gets better with the dkms driver but there is still the occasional datagram UNMATCHED. I don't want them.

I have seen in the past that all Intel network adapter perform better than this. So I will add an Intel network adapter to this mini-PC.
What I have in mind is to replace the WiFi card with some kind of ethernet card. The WiFi is an M.2 card, size 2230.
That's the options I have. No PCIE, no mini-PCIE. Just a M.2 2230 E-key WiFi card position.


 

Hi Guys,

Thanks for feedback.

Now we added hal pins for jogging xyz in pause state.

The halui pins are unreachable from within the tpmod component.
Then tpmod has it's own hal pins for jog in pause.
 

For the one's who still want to do keyboard jogging in pause state, like plasma cnc's  :

• enable the jog keyboard hal pin.

This to prevent unwanted moves by accident.

Yes, it sound like the old firmware issue.

One known way to fix this is to reflash the firmware on a RPI4

Another possible fix is to temporarily short RPI GPIO8 to GPIO25 (40 pin pins 22 and 24)
or if that does not work, temporarily short RPI GPIO25 (40 pin header pin 22) to Gnd

Then remove the connection once the card has been re-flashed.
