Jerking during movement

Jerking during movement was created by foxington
hello,
anybody knows how can be added e1000e.ko driver or 8190too.ko driver beside generic.ko driver of ethercat control network adapter?
I have this hardware
Ethercat is on enp16s0 = rtl8139 and should be at enp25s0 = e1000e.
I have just probem with jerking during movement... It looks like hardware problem but I do not know on which side... If it is on slave side or master.
I have just benchtop setup for experimenting purposes and error runs through all axis in the same time...
I have checked everything from slave DC, custom component code, shielding of cables, core isolation, etc....
I am controling the servos with this component
Component is very similar to cia402 from mr. dominik braun but It was customized for incremental interface of ds402 standard...
thanks for any ideas
anybody knows how can be added e1000e.ko driver or 8190too.ko driver beside generic.ko driver of ethercat control network adapter?
I have this hardware

description """
HAL Interface for ds402 Devices,
this component acts as a glue layer between hardware to Hal modules like Ethercat, CAN-Bus or others.\n
It translates raw IO Data from the PDOs to the common linuxcnc Hal pin structure and has build in logic\n
for the ds402 State Control, feedback handling, external homing and build in scaling functions.\n
It delivers two functions: read_all and write_all.\n
The concept of integration in the correspondending task should be as following: \n

By default the component is set to CSP Mode,\n
CSV Mode could be selected with an:\n
setp ds402.0.csp-mode 1 in hal.\n
Mode changing in runtime is currently not supported, to avoid\n
unwanted behaviour.\n
For using the servo drives internal homing procedure configure your\n
joint homing to Home on Index Pulse only and connect the components\n
home Input to the index-enable Pin:\n
HOME_SEARCH_VEL = 0.0\n
HOME_LATCH_VEL = 0.2 (Any value but zero, the homing speed is predetermined by the drives configured speed)\n
HOME_USE_INDEX = TRUE\n
If you are using PIDs, don't forget to connect the PIDs index-enable pin.\n
Even though this component exports many pins, you can choose which functions you want to use:\n
If you would like to use the DS State Machine, connect Statusword and Controlword.\n
For single use of the scaling function connect only the fb and cmd pins from position or velocity.\n
If no Drives homing is needed, let the Pins unconnected.""";

}Component is very similar to cia402 from mr. dominik braun but It was customized for incremental interface of ds402 standard...
thanks for any ideas

The only way I am aware to change from generic is if you built the IgH ethercat from source. I am not sure how to change from "generic" other than simply trying your device in the ethercat conf file when you "sudo pico /etc/ethercat.conf". I think what you are looking for would need to be done from a source build as I have not changed anything under the repo build that Rod Webster put up.
I really think this is a configuration problem but that does not mean it isn't a hardware problem as you believe. I have not seen Dominik here in a bit to give any input.
When I do the IgH build, I disable the rtl8139. Give me a few hours and I will post you a set of instructions to do the source build. I am busy, but have a set of instructions I was going to post anyway. That way you can try it out and see if it helps you.
Thanks,
Robert

Source is here
gitlab.com/etherlab.org/ethercat
Build instructions is here
gitlab.com/etherlab.org/ethercat/-/blob/master/INSTALL.md
And yes their repo used in the Ethercat sticky only includes the generic driver.

@foxington,
Rod Webster had replied to you while I was putting the instructions up, and gave you the IgH links... If you didn't get it figured out you can take a look if it will help you.
I have an error in the "clone" sections of the instructions as it turned them into hyperlinks when I posted it. I will get it fixed, but wanted to point it out if you did take a look at it.
Thanks,
Robert

hello,
I think I should found the problem of jerking... It was probably like everyone from you said DC.
There issection with active windowand this I just edit to "600" and it runs more smoothly and without jerking. I do not know it should help anybody... but it should

hello folks,
have anybody had experiences with weird behavior of ethercat, when there are more network adapters on board?
I have hooked up ethercat on first enp25s0 with generic driver(original for ethernet is e1000e) and second enp0s16 is for ethernet with (8190too realtek).
When I have plugged and installed ethercat on single of them, it works fine.. But if I connect ethernet on one of them and ethercat on other of them at same time, ethernet works just fine and ethercat starting freezing... drivers go to bootup menu and lcec crached... should be there some problem with kernel or something else?
Where can I just started digging?
regards Slav
