7i76E Ethernet setup

hmm, maybe due to copy and paste?

I retyped line by line into the interface. Is there more that must be done to the interface file once it has been corrupted?

How did you edit the file? Usually this kind of damage comes from non-ASCII editors
Can you attach the file here?

By:
sudo nano /etc/network/interfaces

and then manually edited in the interface.

so i guess the answer is GNU nano 3.2 editor

nano should be OK

You can save time by setting the interface down and up manually

sudo ifdown -s
sudo ifup -a

rather than rebooting when testing your edits

didnt know if you literally meant -s or if i was supposed to put something else there.

ifdown: option requires an argument -- 's'
ifdown: Use --help for help

auto eno1
iface eno1 inet static
address 10.10.10.1
netmask 255.255.255.0

isnt woking either

Sorry its:

ifdown -a

If the interfaces file do not make the expected
changes in the "ip a" report it usually means there is an
error in the interfaces file

mmarmino@debian:~$ sudo ifdown -a
[sudo] password for mmarmino:
ifdown: /etc/network/interfaces:1: misplaced option
ifdown: couldn't read interfaces file "/etc/network/interfaces"

Well thats what i get! Ive followed another persons bench top mill conversion and we have the same components. If something is wrong with that file could i replace it with his if both setup are identical?

You could also try mine:

well that seemed to work! now i have a ping and can see it. Are these numbers better?

Not great but probably OK,
Worst case you may need to reduce the servo thread rate
from 1 KHz to 500 or 750 Hz
