That is how index is handled by LinuxCNC

Typically LinuxCNC's motion component sets index-enable true
for homing to index or spindle synchronized moves. Then, when the hardware
(or software) encoder component detects the index, it clears its hal position pin
and sets index-enable false to tell motion that index has be detected.

You are right, I was wrong.

Well, I must finish my lathe model for real test...

@deroj

Because I installed it with poetry i can only run the command poetry run litexcnc install_driver inside the folder with sudo

cnc@debian:~/Desktop/LiteX-CNC-11-add-external-extensions-to-litexcnc$ sudo -E env PATH=$PATH poetry run litexcnc install_driver

and the files are really in the /usr/lib/linuxcnc/modules/ folder?

how did you install LinuxCNC?

I am using the official debian with LCNC 2.8.4
www.linuxcnc.org/iso/linuxcnc-2.8.4-buster.iso

another thing you can try, what helped me.

open terminal
> poetry shell
> litexcnc install_driver

Thank you, that helped. But after flashing the board and trying to check with hal im getting this error:

[code]halcmd: loadrt litexcnc_eth connection_string="eth:10.0.0.10"
litexcnc: loading litexCNC etherbone driver version 1.0.0
failed to resolve remote socket address (err=-8 / Servname not supported for ai_socktype)
LitexCNC-eth: ERROR: failed to connect to board on 'eth:10.0.0.10'

<stdin>:2: waitpid failed /usr/bin/rtapi_app litexcnc_eth

<stdin>:2: /usr/bin/rtapi_app exited without becoming ready
<stdin>:2: insmod for litexcnc_eth failed, returned -1

[/code]

Removing the eth: doesn't work either.

So when you cannot ping it, LinuxCNC wouldn't find it either....

Do you use the left or right LAN port from the board?
Only one will work.

And is 10.0.0.10 the IP address you set in the JSON config?

Now i can ping the 10.0.0.10 because I should've used the other ethernet port but i still get the same error

So, what board do you have?

And don't use the "eth:" part in the connection string
