Why real time kernel is needed with board like MESA?

Well guys, I didn't say that it's easy to write a firmware for FPGA (but in Mesa they can, someone just has to give them food!) Or that it's easy to change the code analyzer and the path planner. Easy things are not for us, are they?
What's worse is that we do not appreciate our strategic lag behind the Far Eastern countries !!! There, as you can see, this is a question that always stands, even in front of the scientific institutions for which finances are provided. Are there no such in the Western world? We forget how Arduino, Raspberry and others appeared in the first place!
But, what to do, one day, someone else will try, if it already makes sense. The Chinese people will have flooded the market with cheap $ 100 controllers with a menu half English / Chinese, and we will watch them.
I think that the main difference between - working software (open source) + controller and commercial product, may even be just the installation training and maintenance. While most people think that the difference should be mainly in the built-in functionality.
That's why I'm sure what I'm talking about already exists, but it's not an open source.

Yes, you may think I'm naive, but the truth is that we will have to fight against a very organized "enemy", which scientific developments created by universities with public finances, then distributes them to any company that wants to produce and export them!
I deviated again, sorry!

Can you point out any examples of LinuxCNC not controlling axis's precisely?

Well, it's very difficult to list them, but starting with the one I have on my XC609M metal mill - as well as almost all the Chinese controllers you can find today are made that way. I can look for pictures of the XC609M inside to see its device.
It is no accident that I am writing these things. Their scientific developments yesterday gave them the opportunity today to have a flexible system with incredible capabilities.

teardown xc609m, i think it build from linuxcnc

can build like this controller with RPI + mesa over spi

Personally I like the way the LinuxCNC project is now.
If folk want to have a commercialised arm to LinuxCNC then it is simply a matter of forking it and getting like minded individuals, corporations or whatever on board and doing it. Then you can do what you want and leave us folk that are happy to work on a project not contaminated by $$$ behind.

I never meant to offend anyone. I just Linuxcnc to grow.

In fact, this is also widely used by the Chinese for me, but in the lowest price class controllers - Free DOS + FPGA

DOS (because of it's signle threaded nature) is real time too.
