Ethercat linuxcnc not seeing any slaves

So, I installed linuxcnc fresh, then began the ethercat install per instruction thread. It *seems* to have worked, but there are no slaves displayed when I type ethercat slaves...

So, for sanity I went into twincat, and it DOES scan the servo drives, however it triggers a communication error of wrong data type. I wonder if the 2 are related and something is set wrong on the drives.

Servos drives are omron R88D

Any thoughts on what may be wrong here?

Try

from ethercat master.... seems maybe its not working at the network card level. What did i break? haha

Link down. Did you customize /etc/ethercat.conf ?

I did only what the instructions said up to the point of typing ethercat slaves.

so yes, that would have included typing in the MAC in that file per instructions

checked that file again. seems fine. reran enable, start, status... nothing changes.

 

Mac address and generic driver.
Two network interfaces and you picked the wrong one? Has never happened to anyone...
Ethercat master prints in /var/log/messages. Have a look there or at the end of the huge output of "sudo dmesg" for signs of why it won't use the network interface

only one network port on this machine plus the wifi for the internet.
I *think* im using the right one. haha. I dont see how i cant be.

dmesg spits out 10000 things. last one mentions lan at 100base though

network ip/mac

switched to the second one which i thought was the wifi.. now it says link up. still no slaves though
