Thanks. A couple test runs of this look promising. I will try this out on an actual servo as soon as I find time.
I extracted the zip file then sha256summed it:
sha256sum servo_tuning
9f2f5cb11561d13a6a3a4a62ac4788c9b2ea742844b31f8aeb7327cae0cb9cb9
next I marked it executable:
chmod +x servo_tuning
Then I started it:
./servo_tuning

@MaxEkb77 is it possible to get the source of this?
Unfortunately this does not run my Linux box.
Thank you.

It seems to me that we are all wandering around like blind people in the fog...
I suspect that the cause of the problems lies where no one tries to look for it...
Let me tell you a story.
Some time ago I bought integrated Lichuan Ethercat servo steppers.
I set up LinuxCNC and basically everything worked.
After some time, I decided to buy identical drives for a second machine, essentially identical, only slightly larger, so I used the configuration from the older one.
Everything worked, except the engines did not rotate and the drives did not want to enter the correct mode.
I started looking for the cause, changed various parameters and restarted LinuxCNC until they worked properly, but after another restart they did not work again.
I already knew that the engines were working, but something must have been misconfigured, so I started writing the configuration file from scratch, first with one drive, then adding others...
It worked and everything has been working as it should since then.
Except that these two files (working and not working) are basically identical, and the only difference is in the block order.
If Ethercat is so sensitive to syntax that changing the order causes it to fail, then you can look for tiny errors until you die...
