error finishing read!

Hello,
if I enter the following 

   auto enp1s0
     iface enp1s0 inet static
     address 192.168.1.120/24
     hardware-irq-coalesce-rx-usecs 0

in the file interfaces then the hm2.readTime deteriorates from 800000 to 900000. I have entered everything manually, it cannot be a character set (e.g. at -)
If I enter the following command.
     sudo ethtool -C enp1s0 rx-usecs 0
Then ping and readTime (250000-400000) improve significantly.

Is there a possibility to use the command
    sudo ethtool -C enp1s0 rx-usecs 0
automatically when starting LCNC?
If so, how?
perhaps with grub?
Greetings

 

The entry in the interfaces file should do it but unfortunately
you don't get an obvious warning message if there is a syntax
error in the interfaces file.

You might try:

ethtool -c enp1s0

To see if your interfaces file setting was actually run
 

The file interfaces contains the following:
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

source /etc/network/interfaces.d/*

# The loopback network interface
auto lo
iface lo inet loopback

auto enp1s0
iface enp1s0 inet static
address 192.168.1.120/24
hardware-irq-coalesce-rx-usecs 0



The output of the command can be seen in the appendix.
 

That's the output after rebooting without running ethtool -C?

What Ethernet hardware do you have?

lshw -class network

will show this.

You might check if there is any difference in the settings
from the interface file or manually

This is without the command:
sudo ethtool -C enp1s0 rx-usecs 0

If I do not comment out the lines in interfaces then the command does nothing.

If I comment out the lines, the command brings a big improvement.

lshw see attachment

The second picture in the appendix shows the good readTime. Here I have commented out the lines in the interfaces file and used the command
sudo ethtool -C enp1s0 rx-usecs 0

That's really weird, I have never seen that behaviour before
with Intel MACs.

You can run a program at linux startup by adding the command to rc.local
(simple) or using systemd (more complex)

As far as I understand he has to comment out this line:

source /etc/network/interfaces.d/*

Hello Julian,
I had already commented out this line as a test, but that didn't help.
I now simply call the following line when starting via rc.local:
     sudo ethtool -C enp1s0 rx-usecs 0
I leave it like that.

The installation of LCNC was really annoying! 
In contrast, I like the configuration with hal and ini very much.
I could configure a test axis relatively quickly (homing, limit switch and glass scale) - see: .
Now I'm waiting for LCNC 2.10. This version should include QT-Dragon-Lathe. With simCNC (which I use on my milling machine), the complete screen can be created and programmed quite easily (Python). I'm curious to see what it looks like with Qt-Dragon. 
However, as I haven't yet found a used table lathe for conversion to CNC, I won't be bothering with LCNC for the time being.


Greetings Anton
