For testing purposes with just a parallel port, you could use 2 pins for one signal and invert one in hal
to get differential signals.

As long as the output bits come from the same physical port (say PP pins 2..9),  and the hal addf
order and thread is correct. the outputs will change simultaneously.

The reason ethtool is not found is that it's installed in /usr/sbin/
and that's not on the default user path. (but is in the default root path)

Thank you, but I have to modify the ini and hal file....?
I tried it with KI, but not working...

Awesome work Patrick!
Regarding the spindle, here is my solution for a similar setup, the idea was to be able to keep the drilling operation possible. It works well 
 

Its not working but i got everything to work.

github.com/mgiaco/ecam_cnc/ => axis
github.com/mgiaco/ecam_cnc/tree/probe_basic => probe basic

Now i am try to get manual tool change to work as i like.

Hi, I am new to linuxcnc. Now i got my machine running with linuxcncn and mesa. If someone like to see my config ongoing

github.com/mgiaco/ecam_cnc => axis
github.com/mgiaco/ecam_cnc/tree/probe_basic => probe basic

So my long time goal is to write a program with fusion360 oder freeCAD and then mill with auto tool change on my machine.
So before i go more forward i would like to ask if i need this tool_length_probe  change (github.com/TooTall18T/tool_length_probe) also for the current version of probe basic.

As a beginner it´s really a little bit confusing because it seems that there is alsmost everything ther in probe basic now in the actual version. I wachte the  video from ToolTall18T but this is 2 Years old i think. So can someone give me some help here?

Thanks alot.



 

once all that's done, do the ping command PCW asked for and share it. It should be pretty good now.

type: sudo ethtool --set-eee eno1 eee off

this will be lost on boot so to make it permanent
type
sudo grub-customizer
open the second tab and on the line it says quiet, add: igb.EEE=0
save and reboot. 
check eee is off again with ethtool

With energy efficient Ethernet enabled, sometimes your NIC has a holiday which is not good for latency

Also type man hm2_eth and follow the instructions so disable coalescing if you have not done that yet on your 10.10.10.1 NIC

Very nice
Set BASE_PERIOD to 5000. spindle_at_speed works correctly.
Thanks for help !

sudo ethtool works 

I have several motor controllers that are driven by differential signals (CLK, #CLK, DIR, #DIR) – the inputs (5V, Ri = 120 Ohm) are not optically isolated. At first glance, it seems that controlling it with my Mesa 7i76EU works perfectly.

For testing purposes, I'd like to use the parallel port or possibly a RP2040 – in addition, I have a "Benezan Mini Breakout Board" left over from a previous setup that I could use.
It would be great if there were a solution for this.

probably needs sudo ethtool

I installed ethtool and I am still getting command not found 

I did a video recently about this
