Industrielle Linux CNC 5achs Fräsmaschine

Guten Tag,

Ich möchte eine Industrielle 5achs Fräsmaschine auf Linux CNC umrüsten. Das Ziel ist es eine zuverlässige und genaue Maschine. Der Umbau dient als Testversuch um später evtl unsere Produktionsmaschinen ebenfalls auf linuxcnc umzurüsten.
Die Maschine hat servos mit encodern verbaut, es können aber gerne neue Motortreiber verbaut werden.
Der grobe Plan bis jetzt ist: Mini PC mit Linux CNC, Motoren über ethercat ansteuern. 

Die Frage ist jetzt ob das gleich zuverlässig und schnell wie eine mesa karte ist, und welche Komponenten die ideale lösung sind.

Ich freue mich über Tipps!
 

Ja bezüglich der mesa karte, wie ist das mit Latenzen? Welche würdest du empfehlen für 5achsen servos mit encodern?

Once your drives are connected with LinuxCNC, it won't care if you have Mesa cards or ethercat.
Ethercat may be more complex to install 

So do you have any recommendations wich brand of ethercat drives to use for minimal setup and maximum stability? How big of an issue is hosst PC performance with ethercat ?
Is the importance of host PC performance comparable to a mesa card? Or more or less important? The thing is that for the first evaluation of Linux CNC we will use a mesa card, as it's the cheapest and quickest way to test it, but later we would like to use ethercat drives.

In my opinion, Ethercat is a great solution for small machines that can use integrated drives.
I have mills where the individual axes are connected to the rest of the machine via a one patch cord and one power cord, and things like homing limit switches  or other sensors are connected locally to additional drive inputs.
Such a machine is simple to wire and, in my opinion, more reliable.
However, if all the control is to be located in one cabinet and long and multi-core cables are to be run, Ethercat loses its advantages for now. It's just expensive and difficult to set up, and what's best about it becomes secondary...

Nonsense. ethercat drives whole factories. The advantages of ethercat remain regardless of the size of the machine. Ethercat should be a more efficient protocol than mesa hm2 so it should have more efficient bandwidth utilisation. Linuxcnc won't care if you use mesa or ethercat

We don't talk about what is used in industry and why. We are talking about using Ethercat in a machine controlled by LinuxCNC. And here we have factors such as the availability and quality of documentation, sample configurations, or tools, and here Ethercat loses to Mesa. Therefore, I believe that unless there are compelling arguments for Ethercat, it is better to use Mesa. 
"Ethercat is faster" is not a valid argument, because anything that is faster than the required minimum will be sufficient.
