Rod,
I wish some of our LinuxCNC Gurus would know some of the ROS Gurus and
jointly meditate over this. We should possibly not discuss this too much
as a sole CNC/robotics problem. This tech is useful whenever you need to
synchronize something between multiple machines/devices.
I truly don't know what we should be doing as a community. Anyone close
to ROS?
Best,
Steffen

You have done some amazing work and we now know what we are dealing with
rather than just guessing as we've done before.
I think its not about the last 20 years but about the next 20. I think we
will see an increasing number of ethercat capable devices in use as more
vendors adopt the technology.
There are also an increasing number of linuxcnc users using the software on
commercial projects and retrofits of commercial machines.
ROS appear to be simply embedding the SOEM in a sub folder in their
ethercat master wrapper based on an article they link to in the readme. I
guess they can do this under the GPL.
Any restrictions appear to be placed on users of the technology, not the
software developer. Linuxcnc does not use software, our members do. This is
an important distinction.
I think this allows Linuxcnc to treat the proposed driver as being GPL'd at
a distribution level like ROS has.
Now we know of the SOEM's existence, it would be preferable to use it over
the IgH ethercat master if it's compatible with our architecture. It's a
much tighter integration then.
It's clear that membership is not required. I can't see any impediment to
building a separate repository like has been done with mesaflash that
embeds the SOEM like ROS has done. If the rules change, it will be simple
to excise the orphaned child or just remove the SOEM subfolder.

Hi Marc,
yes, something like http://wiki.ros.org/soem ? I have not followed that
up.

Hi Steffen,
By ROS, are you referring to Robotic Operating System (
https://www.ros.org/)?
