I've never seen the sysv error before. 
Odd others have got the new method working already.
You need to use sudo for systemctl and journalctl. Can you redo and share?

check the output of these command

Code:
systemctl status ethercat.service sudo journalctl -xeu ethercat.service --no-pager dkms status | grep -i ethercat        # module built for running kernel? uname -r                              # running kernel matches? lsmod | grep ec_                     # loaded? sudo modprobe ec_master              # manual load - shows real error


Is your /etc/ethercat.conf properly set?

[Forum/internet is being really unresponsive, bear with me]

Thanks gents for having a look.  Here's the terminal outputs:

You need to use sudo for systemctl and journalctl. Can you redo and share?
Warning: Spoiler!


Is your /etc/ethercat.conf properly set?
Yes.  Added MAC addr for enp2s0 and "generic"

check the output of these command
Code:
mill@debian:~$ sudo dkms status | grep -i ethercat [sudo] password for mill:  ethercat/1.6.9: added mill@debian:~$ uname -r 6.12.86+deb13-rt-amd64 mill@debian:~$ lsmod | grep ec_ typec_ucsi             69632  1 ucsi_acpi typec                 114688  1 typec_ucsi roles                  16384  1 typec_ucsi usb_common             16384  3 xhci_hcd,usbcore,typec_ucsi mill@debian:~$ sudo modprobe ec_master modprobe: FATAL: Module ec_master not found in directory /lib/modules/6.12.86+deb13-rt-amd64

So it looks like something didn't get installed properly despite just pasting the linuxcnc-ethercat apt stuff from GH instructions.

And the contents of make.log referenced in the "Error!" line in last post:

try the commands below

Code:
sudo apt install autoconf automake libtool pkg-config linux-headers-$(uname -r) sudo apt --fix-broken install      # clears half-configured linux-image/headers sudo dkms autoinstall dkms status | grep ethercat        # want "installed", not "added" sudo modprobe ec_master sudo systemctl start ethercat.service

This is mostly due to missing dependencies, I will add the additional dependencies to the package, should not happen next time.

That seems to have worked, sort of.

I got the following errors while pasting the commands:
Warning: Spoiler!


fix-broken install and dkms autoinstall seemed to have worked (no errors)

dkms status | grep ethercat reported "installed"

systemctl status ethercat.service:
Warning: Spoiler!


But final commands got an error:
Code:
mill@debian:~$ sudo chmod 666 /dev/EtherCAT0 chmod: cannot access '/dev/EtherCAT0': No such file or directory mill@debian:~$ ethercat slaves Failed to obtain number of masters: Failed to open master device /dev/EtherCAT0: No such file or directory I wonder if the "dev" folder is for a RIP install?

sudo apt update and upgrade seems to have fixed whatever was wrong.

after reboot:

mill@debian:~$ sudo systemctl start ethercat.service
[sudo] password for mill: 
mill@debian:~$ ethercat slaves
0  0:0  INIT  E  AS715N_sAxis_V0.10
1  0:1  INIT  E  AS715N_sAxis_V0.10
2  0:2  INIT  E  AS715N_sAxis_V0.10
3  0:3  INIT  E  AS715N_sAxis_V0.10

I think I'm in business.

Thanks a ton for the assistance.

Spumco, great work. If you have to manually start the service each time. sounds like you overlooked the udev rules in the first post, Sorry about the formatting errors but its an awful post to edit

sudo geany /etc/udev/rules.d/99-ethercat.rules
and the following code block.

Rod - I hadn't actually gotten to that section of the installation yet.  The first 'ethercat slaves' check is before the 99-ethercat.rules line.

I just stopped when I got the errors starting ethercat service for the first time.  Bulldozing ahead past errors has not served me well in the past, despite my habitual attempts.
