Not a specific recommendation, but in general I would suggest
hardware with a Intel rather than RealTek Ethernet interface
(as this avoids the needed DKMS driver installation with RealTek
and newer kernels)

G-code file loading at G53 instead of G54

Category: Qtvcp

Ok great we are getting there.
I'm now betting that these debug lines are showing the problem:
libnml/buffer/shmem.cc 320: Shared memory buffers toolCmd and toolCmd may conflict. (key=1004(0x3EC))
libnml/buffer/shmem.cc 320: Shared memory buffers toolSts and toolSts may conflict. (key=1005(0x3ED))
libnml/buffer/shmem.cc 320: Shared memory buffers emcError and emcError may conflict. (key=1003(0x3EB))

Unfortunately I don't know what would cause this message.
Hopefully someone else will see and help us. I'll look at your INI some more tomorrow.

G-code file loading at G53 instead of G54

Category: Qtvcp

Thank for your the response. Here is some more information in response to your suggestions.

This first image is the machine showing G53 coordinates. The tool is in the center of the work envelope, as you can tell by the non-zero coordinates (0, 0, 0 is the top front left corner). 
File Attachment:

This next image is after having switched to G54 using the gui button. As you can see, I set the G54 origin to be the current position, so it reads 0, 0, 0 while the tool is in the center of the work envelope. The work envelope image shows the work offset origin (3 vector arrows) as at the current position, as expect. This is all behaving as I expect.
File Attachment:

But when I look at the offsets table, it hasn't reflected the changes to the G54 origin. No values have updated.
File Attachment:

More so, when I clicked on the G54 Z value of 4 and tried to directly change it, I got this error, with the full text copied below.

I just tested it. When I restart the system, the link is down. with
lsmod | grep ec_generic
sudo modprobe ec_generic
lsmod | grep ec_generic

it works again

This is enough of a workaround for me. I can also do updates in the future with a clear conscience?

Wow! It works.I was ready to give up.
I don't know why it didn't work for you, exactly. More than there was a problem to load the ec_generic module using the ethercatctl script.
It will probably not work next time again.
I don't know of a permanent fix, but the two commands "sudo rmmod ec_generic" followed by "sudo modprobe ec_generic" will probably load the ec_generic module.
I don't know why it didn't work right away. But there is a fix.

thank you for your answer,
so the code block is included like your post and i didn't get an error.
The change of the length in Z is working (with apply) but the diameter doesn't change still not.

Intel I226 I see. I like those I226es. Then there is possibly the option to use the igc driver instead of the generic driver. You can always test that.

Let's continue with the ec_generic.
The output shows that it is back to the ec_generic module not loading.

Can you show the output of these three commands? It should manually load the ec_generic module.
lsmod | grep ec_generic
sudo modprobe ec_generic
lsmod | grep ec_generic

G-code file loading at G53 instead of G54

Category: Qtvcp

Ok ill see nothing error ing in qtdragon.
I do see some weird errors about tool stat. But let's put test aside for the moment.

What I see based on your screen shots.
- g54 has zero offset for x and y so will be the same as machine zero position.
- you have a small offset in g54 z and while hard to see i think that it is honoring that.
- the offset table shows the same but also shows you have a rotational offset. Yes those z offset numbers seem weird.

I would cancel the rotational offset.

If you wish to move the g54 offset move the machine where you want g54 0 to be and press ZERO on each axis you wish to zero.
After that is done switching between ABS and G54 should make the DRO change the amount of offset and the offset will be shown on the offset table.

This is interesting...
Looks the same. I changed my device to the same settings you have and it still works.
Is it a Realtek device? Which kernel module does it use? Find with the command "lspci -k" and find the network adapter.

I looked in the source code for when it rejects a device and this is what it says in the ecdev_offer() function in module.c:
* The master decides, if it wants to use the device for EtherCAT operation,
 * or not. It is important, that the offered net_device is not used by the
 * kernel IP stack. If the master, accepted the offer, the address of the
 * newly created EtherCAT device is returned, else \a NULL is returned.

There are some debug outputs that can be interesting. Unfortunately the debug attempt before failed
because the master is configured before the debug can be set in the way we tried before.
But here is a way.
First stop the ethercat server with the command "sudo /usr/sbin/ethercatctl stop".
Then copy the the file /usr/sbin/ethercatctl (it is a script) to a new name like ectl and change the line as shown
sudo cp /usr/sbin/ethercatctl ectl
# ... edit ectl and add debug_level=1 to this line a shown around line 126 in ectl

    # load master module
    if ! ${MODPROBE} ${MODPROBE_FLAGS} ec_master \
            main_devices="${DEVICES}" backup_devices="${BACKUPS}" debug_level=1; then
        exit 1
    fi

# Make executable
chmod +x ectl
# and start the ethercat master, then reset debug level to 0. It produces a lot of info
sudo ./ectl start
ethercat debug 0

sudo dmesg

Then have a look at the output, the lines around the configuration is important.
