Ver 2.9.4 iso clean install Trouble when disabling EOE

Thanks everyone. 

Now I can make Yaskawa Sigma X  OP state and jog move from LinuxCNC stably.  ( Just did EoE disabled. )
Slave : SGDXS-xxxxA0x EtherCAT(CoE) SERVOPACK Rev02.09

According to the specification on Web, ( www.e-mechatronics.com/product/servo/sgm...c/xs_ether/spec.html )

LRD, LWR and LRW   seem to be supported. (attached image)
 
​​​But Sorry, I'm not familier with this problem.

Which configuration seems to be better in this situation?

refClockSyncCycles="-1" , with messages "Failed to get reference clock time: Input/output error"
refClockSyncCycles="1" no messages

Should I check some error from log? 



 

+1 if you have good latency

Ok, well that went over my head. Was so focused on the LWR issue.

You need to get rid of most of the "UNMATCHED" messages in the syslog.
"UNMATCHED " are usually caused by bad latency or very commonly by using RealTek network adapters.
If you have a Realtek network adapter, you should install the r8152-dkms or r8168-dkms driver via apt.

Can you show the output of "lspci -k"? Only the network interfaces are of interest.

Thank you so much.
I had been using N100 PC (or such Atom CPU )  for CNC machine, but this time, I installed LinuxCNC to Dell small PC ( 4 core i5 CPU ) just because of having smaller latency and more CPU power.

I have attached lspci - k output. 

I use N100 miniPC with good success. Anyway.

Yes, you have a Realtek network adapter.
 

Please install the r8168-dkms driver
"sudo apt install r8168-dkms"
 

Did you build ehtercat yourself?
My two cents, don't use the official build, make one yourself with disable EoE disabled, and use good shielded cables.
