John,
No, the video isn't relevant to the original question, the attitude expressed
in the video may be. "I figured it out, it took me 5 seconds, 5 months, and
after I did I wondered why it took so long because it was so easy" . I think I
know why he does that 🙂
Some folks like figuring thing
Thanks Martin,
His question and the subsequent discussion on the MACH group has morphed in now
discussions on whether to use closed loop steppers and ethercat. Not sure why
everyone is so fond of leadshine closed loop steppers but what do I know. I
like my AC servos.

Hi John,
I am a member of the Mach group from Yahoo times, I don't have the rights to
post (don't want them either) but sometimes​ the discussions are interesting.
I do know the original poster has a robot but didn't want to use it because it
is too expensive for the task.
With that in mind m

I have rarely run LinuxCNC on an antique computer. Most of my
installations have been on brand-new hardware.

Interesting video and an impressive amount of work done.
I have some comments:
I think it would be nice if all of the LinuxCNC I/O could be connected
using standard ethernet and IEEE1588 for time synchronization. This means
that a servo drive needs to be developed
that has an ethernet connection t

I think you have just described Ethercat. There are open source Ethercat
master and slave implementations (soem and soes). The slave requires a
Microchip interface device (LAN9252). I would like ethercat interface to
steppers of various sizes, and may work on that this summer.

Actually What I described is not exactly Ethercat but more similar to
Ethernet/IP with CIP Motion. Ethercat is not standard Ethernet and that is
why the slave requres the mictochip interface device. But if open source
master and slave implementations are available maybe that would be a good
possibi
I do wish that Ethercat was truly open source from the ground up.

Greetings all;
I've a cascade of scripts that build LinuxCNC on my rpi4, or did, but
something has changed, and my make-debs, now bails out quickly.
I have a script that builds to the end of runtests, works fine, then the
next one makes the debs, but its stopped working with this error chain:
