These would be the new .hal and .xml file + the error code i got after starting
I made this data like the video told me to, expect the card config but im using supported base cards so i just changed the names for them

There was a guy here just the other day that had EL1014 with a different PDO mapping
forum.linuxcnc.org/ethercat/57773-etherc...slave-signals#338260
Maybe it is something like that?
Can you also post the output from the command "sudo dmesg | tail -30" for error messages from Ethercat master.

Check "ethercat -p 3 pdos" and "ethercat -p 4 pdos", if they have PDOs at 0x3101 than that's the problem.
Check the link for how to configure those EL1014 with lcec_configgen -typedb=falseĀ 
and insert this into ethercat-conf.xml for slave 3 and 4, the EL1014s.
