Hi Gene,
So once you've bought the controller, there is no other restriction. And

No, they don't charge twice.

I was not specificaly seeking the monetary cost, more the loss of rights,

As far as Beckhoff are concerned this isn't a free lunch. Similar to

Rod,
Thank you tons for these pointers. This is a nice examples for a) and b)
of my motivation coming togther.
I'd love to see EtherCAT properly hooked up with LinuxCNC (I actually
thought this was the case already) and I happily help to get there. The
problem: I am not competent to make any
Stefan,
One area that could reduce dependency on Mesa hardware would be to bring
Ethercat into the Debian repos. We mention it is being supported in our
shiny new repository entry but it's not and it's difficult to install on
newer distros.
There is an ethercat driver for linuxcnc here:
See:
I have asked this myself. Why did I want this to happen - and I think
the answer is two-fold:
a) community-forming - not necessarily I am after contributors to
LinuxCNC but I see the extra stimulus to package other CNC-related
software for Debian from which then LinuxCNC benefits
b) less stress
This is amazing... This will make Linuxcnc even easier to access.. Game
changer? Maybe!
