Nice work, excited to test it out!

I am reminded of Excessive Overkill's youtube channel (around 18:39):  

 

Yes, this does not seem to be a latency issue but a connection issue.
Not really sure what the cause is. I have a 800 G1 here running
LinuxCNC without any Ethernet connection issues so I don't know.

Is is possible to try another PC to try and isolate the issue?



 

Rod, no amount of tuning is gona help on a disconnected link.
-
Did you change the cable?
Do you have a USB-to-LAN adapter to test with?
Do you have another PC to test with, any PC with a different cable.
-But, only after the Mesa is connected and trying to run LinuxCNC.

There are a lot more tuning settings required but lets get the main one
Can you type: echo $(nproc)
and then back in grub customizer add isolcpus=X where X = $(nproc)-1 from what is printed from the line above.
Then reboot.

My bad the PC is actually a HP Elitedesk 800 G1 USDT 
AMT is not disabled in BIOS where can I find those settings?   

OK a 8300 USDT uses Intel hardware and should be fine

Is AMT disabled in the BIOS?

So some background information my plasma table electronics and mesa 7i76e are not new the PC is new a newer HP elite 8300 USDT I swapped it out recently following issues with this post forum.linuxcnc.org/plasmac/53087-qtplasm...e-0-in-middle-of-cut 

I am not sure how do I find host hardware? 

is the

ip a

result still reasonable?

What is the host hardware?

how cool is that! great work! that opens a huge door for older Heidenhain scales to ethercat without the need of exe's. thank you very much!

I still get the same error after disabling eee 

The sudo grub-customizer did not disable eee for me.   

you will need to connect the joint position hal pin to the respective vismach hal pin.
This can be done in either the INI or a hal file.
For an example see

I do actually like the way the spindle encoder is mounted. Unfortunately, I already sourced a SICK absolute multiturn SSI encoder ATM60-A4A 13x13 bit a long time ago and only paid 65 EUR for it - or I'm going to use my leftover Baumer OG73 S SN1024 1V_pp encoder, which I received as a gift a long time ago. In case neither implementation works out as it should, I'll have a detailed look at your encoder ( AliExpress Link )

Back to the modified EL5021 terminal: I couldn't believe that it was that easy to modify it and be able to read the encoders back. That's when - as any sane person would do xD - I got into the car, drove to my parents' house, and tested the modified terminal on the Maho CNC mill. What can I say, it's working like a charm, even on the first try :o So, yes, an EL5021 Beckhoff terminal can actually read 11µA_pp signals and you only have to modify 9 resistors in total. A rudimentary schematic is attached I'm not able to measure the capacitance of the capacitors due to the installed resistors within the circuit, but their values shouldn't really matter (maybe an RC low-pass filter is no longer tuned as it should be, but that shouldn't cause problems here - I hope). I documented the very first test of the modified terminal and uploaded the video to YouTube.

I've also attached a screenshot of the CiA Danfoss VFD diagnostic tool for anyone interested
