[Emc-developers] Commercial Services

[andy pugh]

A forum discussion seems to suggest that there is some market for
commercial LinuxCNC support.
http://www.linuxcnc.org/index.php/english/forum/38-general-linuxcnc-questions/29872-linuxcnc-propaid?limitstart=0#64660

Before I go ahead and create a forum section (or see if I am able to
create a forum section) where people can offer LinuxCNC services for
money I thought I would run it past the members of this list.
The section should probably have a sticky message saying that LinuxCNC
itself is free and can not be charged for, and that any contract is
purely between the integrator and the purchaser with no liability owed
by the LinuxCNC project.

Any other thoughts? Any objections?

I have absolutely no plans to ever offer any commercial services myself.

Somewhere in that Chinglish blurb, it says something about 
Load LinuxCNC, INSTALL DRIVER and go.
So, I guess they have a custom driver.

That's $140 just for the PC with LinuxCNC loaded.
The Ethernet driven "servo" card is $249.00  (Looks like step and 
direction output)

So the package is $400.00

I can see them making that work money wise in China.

I suspect you can pickup a 525 clone motherboard over there for $40 or less.

GPL...  ?   As long as they state that they are not selling LinuxCNC, 
how could get they get trouble with that?
I don't know if they actually state that or not.

Besides, doesn't all licensing and licensing legalities stop at the 
China border?I'm pretty sure that Mach3 is freely exchanged in China.
When I was there a couple of years ago the local engineers told me that 
they routinely bought American movies on DVDS as soon as they were 
released to the theaters in the US.

He said the DVDs cost the equivalent of one dollar US or less.

Re: [Emc-developers] linuxcnc-features in linuxcnc?

Hello Sebastian,

I must admit you took me by surprise when you wrote you wanted to 
include features in next stable release.
I knew it would be interesting but I though that it needed some more 
refinements before.

I have a tight schedule currently and cannot spend much time to rush the 
project.

It seems that you deleted bringing_features and I do not blame you. I 
hope you still think that it is a very good add-on
to linuxcnc, nothing else comes close. Since I wrote more than 90% of 
the code I am the one that knows it best and I will help you.

But you should not work with version 2.0 it is outdated, having been 
released about 4 months ago.
Version 2.01 released last month is much better. They both have much 
code and files to delete.
Those releases were the first I made and it was some kind of market test 
to find the interest.

I believe version 2.02 will be ready to include in stable linuxcnc and I 
am proposing you what I know will work.
Please correct me on what does not fit your view.


Features depend on a good directory structure and links to those 
directories.

APP_PATH : /usr/features
files in this dir : features.py
 features.glade
 features.ui
 CHANGES
 README.md
sub-dirs :  catalogs
 lathe
 mill
 examples
 graphics
 images
 ini
 lathe
 mill
 lib
 support

Working dir : $HOME/linuxcnc/features
 link to APP_PATH/features.ui
 links to APP_PATH/...
 catalogs
 examples
 graphics
 ini
 lib
 support

USER_DATA : $HOME/linuxcnc/features/user (not $USER, full access)
 (preferences file will be saved there, no need to create)
sub-dirs :  catalogs
 lathe   (files that will be saved here : default 
template and history)
 mill(user will save his modified menu.xml)
 graphics
 ini
 lib
 scripts (or the name you think is best, this is where 
resulting file 'features.ngc' will be saved)
 xml
No files need to be created. This is where the user puts his 
modified files.
Features will first search files in USER_DATA and use it if 
found, else it uses APP_PATH


Links needed :
 /usr/local/bin/features to APP_PATH/features.py (stand alone from 
anywhere, no need for args, everything from defaults or preferences file)

 /usr/share/pyshared/gladevcp/features.glade -> APP_PATH/features.glade
 /usr/lib/pymodules/python2.7/gladevcp/features.glade -> 
APP_PATH/features.glade
 /usr/share/pyshared/gladevcp/features.py -> APP_PATH/features.py
 /usr/lib/pymodules/python2.7/gladevcp/features.py -> 
APP_PATH/features.py

 optional :
 /usr/share/pyshared/gladevcp/features_user -> USER_DATA


Files to edit :
 /usr/share/pyshared/gladevcp/hal_pythonplugin.py
 /usr/share/glade3/catalogs/hal_python.xml


Linuxcnc ini files
 axis-features.ini, axis_mm-features.ini and axis_lathe-features.ini 
could be added in sim.axis
 without any other files
 OR
 sim.axis.features dir could be created with the needed files

 Similar option for gmoccapy


This is what I am preparing for release 2.02
I hope to have it ready in less than one month. Some new features I am 
adding are very difficult to implement, gcode is terrible IMHO.


Regards
Fernand

Selling a PC with LinuxCNC preinstalled is "commercial distribution", so
absolutely they have to take several positive actions to be in
compliance with the GPL.  See the GPL version 2 section 3.

Yes, I know that as a matter of practicality nobody is going to 'get
these guys' for copyright infringement, whether of LinuxCNC or Mach or
any other software.

I don't take a position on whether to add this to the forum.

However, if the consensus is to add it, and you haven't done so yet,
please wait until after the forum transition to add this forum.

That should be this weekend if all goes according to plan.

Thanks,

  And that price is for the pc only. The controller pcb is sold for $248. 
Even for the pc by itself the price don't look right. The components 
only for that should be in the order of $215

Re: [Emc-developers] Spotted on Ali-Express (Via the forum)

[TJoseph Powderly]

another misconception on my part.

i thought use of ethernet & hardware stepgens
drastically reduced the need for fast pc threads.
that latency didnt matter as much.
i thought that 25 or 35uS latencies didnt matter.
that even a 525 would work well given proper interface boards

for me it's always buy/try/toss/repeat.

i've got the inventory of boards listed on the latency test pages
that just do not yield the same ( or remotely near) results

people on the boards forums lists constantly pontify about some new mobo.
caveat emptor: make sure of the return policy first. then test for a week
( consider that Fanuc and Mitsubishi and Heidenhain might do as much )

Thx for letting me know your actual experience.
i consider that to be of value.

i must agree that cheap and good rarely get together

I would not buy this device.

Whatever "motcat" is, there is no driver for that in the software from
linuxcnc.org.

I would also be very surprised to hear these guys are meeting their
obligations under the GPL, too.

That seems a bit cheap. Also the D525 is not the best choice. I have on 
on my mill and it suffers a bit with performance.

No  objections.  It is my impression that we have a sufficiency of people 
here who CAN help out commercially as some are, Viesters being a good 
example but not the only one.  The problem is one of suitable pricing so 
that the individual can actually make money doing it.  So I'd say that 
any fees charged, would have to be timed from when the key goes into the 
switch to go to the problem site.

Other than that, the best support by far, with only one other mailing 
list of the many I am on, having support on a par with what I have been 
freely given on these 2 lists. For the support I have been given freely 
right here on these two mailing lists, I try to make sure the thanks go 
back to the person answering my occasionally dumb questions.  I hope 
that I haven't slighted anyone.  My apologies if I have, it certainly 
wasn't my intention.

And yet, with your knowledge Andy, you would be a good candidate.  I 
suspect in your case since your $dayjob seems to be involved with an 
automobile maker doing control software, that the problem is one of 
finding the time to do it.

Yes, I would be far more tempted to swap money for more spare time
than spare time for more money.
