Hello Przemek,
yeah, you are right. The world is changing to more commerce, less
character rapidly. I think this started when the iron curtain fell -
strangely enough, the communist system seems to have been the last part
on manhood to keep up ethics and moral standards. I'm not going for more
and more money since I have been lying on that cool stainless steel
plate in the hospital several times, watching tmy heart impulses dwindle
away on the monitor and awaiting the narcotics syringe and not knowing
what I would be seening next - the world I was used to or St. Peter.
This was OT.
Of course, Linux is in every screwdriver nowadays, but not visible to
the user or customer, i.e., without a UI. It does its work as a stable
operating system without failure. So don't get me wrong, I was using
Unix on work stations as an OS long before the first PC was sold ( I
used to be very familiar with it but all this was overrridden by the
daily office use of Windows products). I learned that with a complicated
system (CATIA) in production, you have to have a reliable software
partner, beginning with system installation and update work and ending
with emergency calls.
If there were software houses offering this service I think LinuxCNC had
a big chance on the market. But we have been discussing this commercial
aspect a while ago in this mail group. It also means that there would
have to be a rigid publication management for releases and their timing.
This all would completely destroy what I like with LinuxCNC. Of what I
heard, Ubuntu, being the base of it, is already turning more commercial
at this time so we can just wait until we need another OS - just what I
meant by "reliabilty and continuity".
You see, I had a Siemens Facility Management system running in my
company for more than 25 years with no trouble other than occasional
errors or part failures. Even the central hard disk was junked later on
without ever having failed during all those years. They even kept up the
ancient OS (BS 1000, the predecessor of BS 2000) although nobody in the
world knew about it any more - they taught their personell only for us
and for the Moscow airport, the only customers left I knew of. That's
continuity! In the end we switched to another system, much more user
friendly, and I can only hope that the company that is selling the new
system will keep on going for a long time.
Of course there is a used machinery market in Germany. But for one,
there is the tax aspect: you can detract more from your tax if you buy
more expensive machines. This is dealt this way by the federal
government in order to encourage investments in new equipment. Then, new
machines are better, have less failures and out times, need less
maintenance and service, are more user friendly, need fewer operators
and can be run by less experienced operators. Thus, they are cheaper to
run. So, the used machine market is a low price market. This way it was
easy for me to buy machinery for my hobby workshop from my allowance
money :-)).
For the mechanical workshop of my former company, of course, I bought a
5-axis Deckel-Gildemeister CNC mill with all the tricks of the trade. It
has a shrink tool holder with modern tools and works so unbelievably
fast that everyone expects the tools to break or at least to become dull
after a few seconds. The spindle turns up to 20 000 rpm in stainless
steel, so all the experienced workers shook their heads when they saw
this for the first time. But aside from the speed, the programming
feature enables the designers to devise parts which were not even
thinkable before, e.g. a cell sieve with 500 by 500 holes of 0.3 mm
diameter made from stainless steel.
When the iron curtain fell, all the used machine dealers in West Germany
had filled their storage with used machines, partly real wrecks,
expecting the easterners to buy all this junk when the border was
opened, and hoping for a great profit. However, East Germany got support
from the federal government (i.e., our tax money) and used the chance to
make a completely new beginning, investing only in brand new machines,
so in the end it came out that they were better equipped than West
Germany after all (which is also true with the roads over there compared
with ours). At the dealers, they had stacked lathes and mills on top of
each other - in fact, I picked my machine sitting in a cradle hovering
on the crane high above a huge heap of used lathes. I used the chance
and bought my lathe really cheap this way. Many dealers went bancrupt at
this time, just as mine did. When I came back to his place after about
half a year in search of more change gear wheels for the lathe even the
building was gone.
So, I had to make my own gears using my home brew software on my home
brew CNC mill. This is what inspired me later to take up dealing with
LinuxCNC. Anyway, to answer your question: retrofitting machines is good
for home and hobby use, not on an industrial base. Don't get me wrong,
I'm very in favour of repairing things (which I am doing constantly
aroud the house). I have been visiting a lot of used dealers, junk
yards and flea markets (and also Ebay) to complete my shop equipment. At
any rate, with a shop full of old equipment you won't win many public
calls for tender (or what may be the correct term for that), because in
many cases the shops inventory will be considered for the decision who
gets the contract. I once had a case that an engeneering company got a
million order because they had a color DIN A3 laser printer while others
didn't.
I think that the US government would do a good thing encouraging its
country's infrastructure to be improved, which is also true with
electrical, water and other energy supply, as well as traffic and
renewable energy systems. Squeezing the last drops of oil out of the
some greasy rocks under ground is the wrong way to compete with future's
demands.

Post by Przemek KlosowskiPeter,
I have nothing but respect for German reliability---but I live in the US
which may have originated the 'fail fast' attitude that, on the whole, is
quite successful. I was raised in the cultural meme of a failed businessman
who would shoot himself in the head out of shame, so it was an eye opener
for me to learn that an average successful entrepreneur in the US failed
and went bankrupt several times before achieving success. We probably pay
for that with less stable economy---when it's cranking it's really
productive, but it's susceptible to bubbles and subsequent recessions.
I think the times are changing and for better or worse the 'fail fast'
model is gaining popularity around the world. Specifically about Linux,
when I look around me I see that all my phones, my cable modem, half of my
computers, and even my TV and DVD player all run Linux. It's an interesting
dynamic---of course all those manufacturers care about stability and
quality, so I imagine that they have internal teams that assure that it
will work out. There's nothing that would prevent a large industrial
equipment manufacturer from doing the same to adopt LinuxCNC. I think it's
bound to happen when the price pressures arise and force people to look at
the component costs---I noticed we have Chinese participants on this list,
who sounded like they are more than hobbyists.
As an aside, is there a market for second-hand machinery in Germany? a lot
of the motivation for LinuxCNC is because people get depreciated machines
from original owners, and they are either broken, or too expensive to
maintain in the original configuration, so LCNC retrofit makes a lot of
sense. I can see how this might be not a thing to do in Germany--would you
agree?
