Hello Rafael,
First; As I said, I am setting up a test bed, not even a CNC, just to
work out how to make some combination of linux-cnc, stepper drivers and
stepper motors work.
Second; When I get it figured out, and I am sure I will, because this
list/forum is great in providing solutions, suggestions, pointers and
positive directions in general etc. I
probably won't use X forwarding, but then again, I might,
who knows.
third; I have no Idea what a caw is, however on my travels I once heard
a breed of parrots being referred to as a caw, and indeed, it would not
make much sense to put a saddle on a bird
like that. Unless you meant cow, in that case, and because of
losing track of the topic, I would have carved out some time to spend on
reading/writing English from those decades
of research if I were you.
fourth: Your email sounds like a Chevy vs Ford, Windows vs Mac vs Linux
rant, no one probably cares.
The fact you, and few others, don't have a solid understanding of linux,
is not an argument. The fact it is open source isn't either. HPC, super
computers, worth hundreds of millions, run
some version/distro of linux. One of the reasons being that the ways it
can be configured, tweaked, modified are enormous, better then one
single OS vendor would ever be able to provide.
Also, I am not sure, but most on this list/forum, are probably not even
professional machinists, there are probably a lot of "CNC enthusiasts"
around, some know a bunch about
CNC machining, some are more software/programming inclined, some are
more OS or electronics inclined. That's probably how linux-CNC came of
the ground, which is pretty cool.
If you look at it, linux-CNC is pretty slick. Granted I had some trouble
installing it, using it, it is not based on the OS of my choice (but I
don't mind/care, and
no one else, except you, probably really does.). The reason for my CNC
"troubles" , I am sure, largely have to do with my own shortcomings, not
exactly knowing
a lot about linux-CNC, or CNC machining in general. It is an open source
project, which means that it is available to anyone. It might not be the
perfect solution, BUT, what is?
One of the big advantages is that as soon as a few people come up with
and idea to implement something, even if a majority doesn't like the
idea, they still can.
With an OS/Application vendor, you're pretty much dead in the water if
you want something they don't/won't implement.
Also, returning back to the topic, you might have heard of LOM, (Lights
Out Management), of equipment, including CNC machines, during your
decades of research where it
actually might be convenient, if not mandatory, to remotely check in
with CNC machines running autonomously. So X11 forwarding might be
useful, who knows.
Anyway, last but not least, to those of you actively contributing to
linux-CNC, most of us here, I am sure, would like to thank you for your
countless hours spent
on making this open source project possible. There will always be those
that are whining and complaining, but they are vastly outnumbered by
those of us
that are happy this projects exists.
</RANT>
thanks!

So X-forwarding would work, and is easy

Running X-windows on CNC machines makes as much sense as mounting
saddle on a caw.
Based on my research LinuxCNC is undesirable in production
environments or as an option in new CNC products. I spent countless
hours to find out if any CNC manufacturer is recommending or including
LinuxCNC with their products. Most small to medium size CNC machines
in built or kit forms, come with Mach or some other thing. When the
subject matter comes up I don't recommend their product because it's
only available on crippled OS.
After decades of proven good records, there is a lot of
misunderstanding about using Linux in small business environments. I
hate to write it, but LinuxCNC is not ready for software option with
new or DIY CNC machines. When I tried to get small business owners or
others at trade shows interested in LCNC I get questions that are
impossible to answer. What kind of computer and other electronics HW
are needed, who's supporting it, how much does it cost, etc.
I can't tell people to come ask questions on this mailing list.
Discussions more often than not degenerate from the lists main purpose.
Suggestions to find a used PC or a motherboard with parallel port are
just silly. That's fine for hackers with more spare time than $$$ in
their pockets but not for serious business owners. During my visit to
EU I could not find a used PC to demonstrate LinuxCNC around.
LinuxCNC is like Apache and such in the 1990s. No serious commercial
use and support. I haven't seen any job listing LCNC as one of the
requirements advertised anywhere.
If things were different, open source community would embrace LCNC
instead of putting their effort into GRBL for example. My choice would
be a headless Linux based CNC controller with suitable drivers for
different size machines. GUI would be running on separate system
connected over ethernet, USB, or even wireless in some cases. Numerous
robots work that way.
