My servo driver uses ethercat and my io uses rv901 fpga card. They both work well together on Orange Pi 5 Plus.

I was afraid to deal with relatively new architectures and ordered a mini PC on a six-core AMD processor:
aliexpress.ru/item/1005007068086214.html
It is also single-board inside.

Tell me, please, was it difficult to configure EtherCAT on Orange Pi 5 Plus and is the performance sufficient? I want to use the computer not only to run Gcode, but also to develop my interface.

 

So the underlying problem is the trajectory planner of halcore. This consumes too much time as it
is also added to the servo update thread. It slows down the servo update thread. I think this is the cause
that the production machine on the parport also run's not good.

So i will qreate a chrono timer, to first measure the total time of the trajectory planners cycle.
I expect it will exceed the 1ms time of the servo update cycle, but i don't know for sure at the moment. We will find that out.

I am following this thread ever since it started as I would be interested in the result of this work, but I have not felt I could contribute in way yet. 
Regarding this slow down update of the servo thread, I don't know if you are aware of how OpenCN (forked from linuxnc) works, I know that instead of using realtime kernel, they've done something where a core of the CPU is allocated to ethercat master and only that core is realtime, while the rest of the cores are doing the calculation work. 
I think this video can explain it better: 
Most likely you were aware of this but I said it doesn't hurt asking. 

I think you have missed the udev rules as per the sticky.

Our old pc hardware on Lathe got broken and we got some other older pc hardware to test with. Everything is running ok with AMD FX-4300
setup. That pc hardware is also very old so, we deciced to upgrade it AMD Ryzen 5 5600G. Software is starting ok and Linux etc. is working ok
also latency test is running ok. When we start the Lathe software, pc restart and there is no error messages in any log?

We got another older pc to test and everything is working ok on AMD Ryzen 5 1600 pc. We even tested newer cpu (Ryzen 5 5600G) on Ryzen 5
1600 motherboard and same issue, pc reboot when starting lathe software. Same motherboard and hardware with Ryzen 5 1600 is working ok.
Motherboard for those test was asus prime x370-pro (compatible for ryzen 5 1600 and ryzen 5 5600g)

First line in setup witch reboot the pc is: addf hm2_5i25.0.read servo-thread (if we comment that line out, software start(no reboot), but not
working ok).

Now we are out of ideas why this reboot happens and is it possible to fix?

hello,

i did ethercat master driver reinstallation from generic to natural which is on the chipset on the board for some performance configuration for time period reduction... everything works well till I do not switch power of slave 24V mains off... after that ethercat master service is still active but bus is death... I have to do 
for restart the ethercat bus ... how to do it automaticly or am I missing something?

regards...

Last night I had the same problem on Raspy 5,
I must have solved it with --fix-missing
as it tells you at the bottom in the terminal
hi

My suggestion is to give up ecat-io and look for other solutions, such as mesa card or fpga or arduino (I don't know how fast they are

But I like ethercat
But it  adds additional expense and complexity.
I am tempted to get one of these to play with it. Once I finish the mesa control box I am working on...

Thanks man, sorry about the frustration.....

Very sorry. I don't have write access to the website so depend on others who I give the ISO to.
Please try my ISO in Google drive, I know it works as I have tested it on real hardware.

I used the latest I could find

Just to be on the same page
Did you use this one:
 

from here:
linuxcnc.org/downloads/

Note, for the gcode to reload you need to switch to the 'AUTO' mode screen in gmoccapy.

Seems likeI lost the hashbang in the first line of the python code in my last post.
I just fixed that, so copy/paste the fixtd python code above and try again.

The kinematic compensates for tool length.

Are you sure you have connected the required pins:
