Ethercat Setup help needed for beginner

That sounds promising... @andrax
To the folllwing error: fault on my side. The servo was set too soft, and when decelerating there was too much play. Set it a bit harder and now it works. 
Mesa card arrives tomorow. Gonna try my best.

When you have come this far with EtherCAT you can just keep on going.
No point in switching to Mesa now. Unless you want a Mesa system of course.

Mesa for my i/o, as i dont have any ethercat 24v i/o. As there might be glass scales in the future, not sure yet. But for general i/o as a jogwheel, pneumatics, Buttons etc. And for spindle vfd. Run, dir, pwm... Mesa cheaper than endless Beckhoff units.
