I have checked my code and we are not doing it either!
I've added an issue to remind me to fix this.
I am out of time now until this evening.
Happy to accept a PR to correct this in the meantime.

I added the "Go to zero" function to "axis_tool_button.py" but it makes little sense from the user's point of view.
What do you think about adding the ability to add such functions in an easier way, maybe in an ini file?

Attached is a screenshot of the output.
Realtek is the onboard NIC.
The Intel NIC works well and has a MAX ping of 0.36 after one hour. 
This command 
 hardware-irq-coalesce-rx-usecs 0
I have not yet tested this command for the new Intel NIC.

Apparently others have already had a problem with the driver!?

Addendum
I have just looked again at my laptop, i.e. the first device on which I installed LinuxCNC, to see which NIC driver is installed there. The r8169 RTL8168 is also listed there. I also had the problem with the laptop with the long ping time.  I have also attached a screenshot of the laptop.

Thank you all for your help.

I managed to find out that this drive works in Cyclic Synchronous Position Mode when using the EMC-MC01 card, which in turn works with Tamagawa encoders that have Data+ and Data- wires and power +/-. (Without the Clock signal!!!)
It is unclear if such cards are available for sale, as I have not yet found a price for them. However, they are mentioned in several documents. I will inquire with the dealer whether such a card exists and if it can be purchased now.

For now, I can only work (in position) with this drive in Profile Position Mode (6060 = "1").
I hope this information will be useful to someone

I commited the PR to conform with the standerd pin names which should make it easier for you to try this component. It needs testing!

Please try my cia402 homecomp.
github.com/rodw-au/cia402_homecomp/tree/main

I went back to the original homecomp code so it should work. I only get small bursts of time to work on this so I forget what is meant to be supported. (My first homecomp was obsoleted by massive changes to the framework)

Note my pin  names are different. There is a PR there to change them back to the default names which I am deliberating over accepting or not. Give me your thoughts on this.

I've had some help from scottlaird and was hoping once this is tested, it would be distributed with the hal ethercat driver.

First there was cia402.comp
Then came custom homing.
marcoreps forked the cia402.comp from here
github.com/dbraun1981/hal-cia402
It definitely switches to homing mode but it was developed on a drive that homed to index 
But it never worked with cia402 external switches. I ried very hard before concluding changes to homing.c were required, then the homecomp was released.

I have also worked on a cia402 homecomp and was hoping it would become part of the ethercat repository in time and the need for cia402.comp would be obsoleted.

Yes, 3 times.... same result.

ok, found the processes....
it's bounding between  halui  and  milltask.
see the image and the file..
So, what's up????


UPDATE
In reading the DEBUG doc, I set

   

Chris.
thanks. I thought about changing the debut in the .ini, but that would only hide the problem.
I'll see if I can find the pid in system info. not sure how to do that but I'll look into it.

#289146  from earlier in the Plasmac Post Processors thread. I am trying to import the tool library file included in that post into Fusion 360 (which is where the error came from).

Hi guys, I have an older PC that had the Debian Wheelzy iso with linuxcnc 2.7.14, I updated the repository link in Synaptic and then updated Linuxcnc to 2.8.4, but the "tandem items" do not appear when I go configure the parallel port pins.
 On one of the axes I have two motors and I want to do square homing as done in this video , but I don't have the "tandem option" to select the two motors and sensors which are on the same axis.
 I'm not using a mesa card, I'm using a PC with a parallel port, how can I solve it? Because from what I researched on the forum, from version 2.8.* of Linuxcnc there should already be this 'function' with tandem items...
 Thanks.

Hello, I get aurh error on last line of these cmds

cd ~
git clone --depth=1 --branch v2.9.2 github.com/linuxcnc/linuxcnc.git ~/linuxcnc-dev
cd linuxcnc-dev
./debian/configure uspace
mk-build-deps
mv linuxcnc-build-deps_$(cat VERSION)_all.deb ../linuxcnc-build-deps_$(cat VERSION)_all.deb
su -c "apt install ../linuxcnc-build-deps_$(cat VERSION)_all.deb -y"

I checked my pwd, I can login ok

but still get auth err when last l line asks for pwd

i tried to circumvent using
sudo apt install ../linuxcnc-build-deps<tab for autocompletion>
but ended with broken packages

this fails as well, same way
su -c "ls"

help!

But implementing the home offset is out of my knowledge

If you want you could give the modified component in the attached folder a try.
halcompile the component el8_homecomp_mod
and then change the name in your ini fromHOMEMOD=el8_homecomp

to
HOMEMOD=el8_homecomp_mod
The modified component compiles on my system but I cannot test anything due to a lack of hardware.
Note this assumes that 'cia402.0.pos-fb' is reset to zero by the homing procedure, if that is not the case we could try the other option used in homing.c, so please check if that pin is reset to zero or not.
 

Also, for anyone wanting to use a touchscreen with Pi5, know that the on screen keyboards seem to be completely unusable at the moment.
