linuxcnc 2.9.2 ethercat problem

I installed it on another computer a few weeks ago and there was no problem.
I think Linuxcnc's ethercat support can be turned off by someone who provides this support whenever they want.
I think Linuxcnc is not suitable for professional use because an installation that could be done last week cannot be done this week.
For example, let's imagine a person who is building a machine with Linux, everything is finished and it is at the operating stage. There is an ethercat problem right now and it can't be solved. How can it wait for it to be fixed? It can't wait, that's why it doesn't use Linuxcnc, it uses professional devices. Yes, Linuxcnc may be free, but it doesn't matter if it is free if it doesn't work when it should.

I buy and use professional devices, I pay money for these devices. I only shared this to prevent anyone from getting hurt. Because I can't do something I did a week ago a week later. For example, who can guess that something that worked a week ago won't work a week later. And since I worked it before, I could start a new job thinking it would work again and I could be disappointed. My aim is to prevent others from falling into these situations. .

I think you are far from professional CNCs. Devices with inputs and outputs that can control 256 axes are 1000 euros.

Also, a person who needs help is a novice in these matters, how can he contribute? Did you start this job by helping directly? Did you not need help at all in the beginning? I have been working on it for a month, I opened a few issues in just a few days, and I only got a half-answer on 1 issue.
