Both Devices are exactly the same. I am moving the Drive+Motor setup physically to his desk. For the code, i have attached the entire code in another reply.
ethercat slaves -v outputs the same data in both systems and both are PREOP + Update: all package dependencies to build the master are same along with version. I was initially assuming (for the sake of ruling out the hypothesis) that some package dependency might have gotten updated since i last built the master in my system. However, all package dependencies are the same. Also, i now tried the Etherlab gitlab stable 1.5 branch in his PC with --disable-eoe option and it works (sparring a few watchdog timeout errors). Why is it not working for the stable/vectioneer branch?
