Network support is the next thing I'd like to include, but it's unfortunately not that easy in a hardware-only design .

i will have a look at FlexiHAL, but FPGA's are not comparable to MCU's and i wanted to avoid to include a soft core

Great job. I have to admit that I only understand 10% (maybe) of what you are doing here. I really like the enthusiasm you are showing.

Could LinuxCNC-RIO also be an EtherCAT slave with something like this:

Thank you !
EtherCAT is not planned and I do not think that it will come

Excited to see the Tang Nano 9K as I recently got one to dabble in the FPGA world. Looking forward to your work on this as I am very new to this area.
