Ethercat installation from repositories - how to step by step

I used it and it worked perfectly with your instructions!!!

 Hi, I'm getting an error running the command：   
    sudo systemctl start ethercat.service
 I don't know what it is, but with that method it works on another device and on this one I'm having problems. 

Any help would be appreciated.
Thanks.
 

hello on my raspberry 5 come this Status

ethercat.service - EtherCAT Master Kernel Modules
     Loaded: loaded (/etc/systemd/system/ethercat.service; enabled; preset: enabled)
     Active: inactive (dead)

raspberrypi systemd[1]: Dependency failed for ethercat.service - EtherCAT Master Kernel Modules.

thank you
 

Hi,
Figured it is time to update my outdated (but still working) instructions for my customers and to switch to Bookworm and a newer version of LinuxCNC, so I'm now running the LinuxCNC 2.9.3 Debian 12 Bookworm PREEMPT-RT ISO.

Next is installing EtherCAT so I started this step by step instruction but get stuck in the beginning.

it works fine on my Raspberry 5 after a clean install

There is another sticky to fix the expired security key

Since I am new to the topic of Ethercat, here is another question. I have now installed a servo( As715N) in my test series, but what is it written as in the ethercat-conf.xml 

   <master idx="0" appTimePeriod="1000000" refClockSyncCycles="-1">
    <slave idx="1" type="EK1100"/>
    <slave idx="2" type="EL1008"/>
    <slave idx="3" type="EL2008"/>
     <slave idx="4" type="AS715N"/>

is that right?

 

I would like to know what steps to take to have qtplasmac gui to work with ethercat
not trying to be lazy, just trying to avoid another 3 months delay because I could not get my ECR86 drivers to work.
rtelligent service actually helped me out and I finally had the axis moving...
I took notes of everything and I will post my findings here ...

I would probably get a working xyz Ethercat config with axis.
Then I would use pncconf to build a qtplasmac config then merge them together by hand

You will need to work out how to sense torch voltage. I would look for an Ethercat module that sensed analog voltage.
This has been done in the past but it was before QTplasmac.

Hello. I installed ethercat following all the instructions. I can see my servo motors. But I can't do anything else. I cannot create the lcec.conf file. Please can you help? (I can't find a clear source because I use Google translate)
