A number of you are really good friends. I'd like to keep it that way.
I plan to keep hanging out in #linuxcnc-devel and I'll try to provide my

Wow! it has been great to have your help with LinuxCNC!
While there may have been some amount of friction, and
possibly some "interesting" side projects that might have
happened in a different way, when you start playing with
moving dangerous machinery, software enters a whole
different arena, and some good deal of caution is very
warranted! I never ran the latest release of LinuxCNC on my
Bridgeport, as all software at least has quirks, and I'd
like to know that MOST of them are at least known before
starting to cut metal with them. I have had AMAZING luck
with LinuxCNC, and have not had a real crash since 1998!
Back then, the RT thread ran without saving the FPU state,
and would cause occasional lockups of not just the GUI, but
the whole X Windows manager. But, EVEN THEN, it would
finish the part, you just had no control other than E-stop.
Please use the remainder of this thread to reminisce about the good
times. For instance, I fondly remember two events in particular from
the CNC Workshops I attended in Galesburg:
1) We're all sitting at the pizza place, and Jon Elson and John Kasunich
are both trying to out-do the other with stories about mishaps with
power electronics. I've still got nothing on even the tamest of their
tales.
I remember a NUMBER of great interactions at Galesburg, and
your completely writing and testing the integer low-pass
component for smoothing MPG jog dials while I talked to
somebody for ONE MINUTE!
It would have taken me a lot longer!
I'm sure John K. has MUCH better stories about big power
mishaps than I do, but I do have a bag of "war stories".
I wish you all, and the project itself, the best.
Thanks for all your hard work! The contributions by Robert
Ellenberg were a huge breath of fresh air, and fixed a
number of issues that some higher-end users ran into. And,
of course, John Kasunich's development of HAL completely
broke the stasis that EMC was stuck in around 1995 -- gasp,
was it REALLY that long ago??!!?? So, I guess it is time for
somebody else to drop in and make some major contributions.
As for me, I'm just barely capable of fixing tiny bugs in my
one driver (ppmc) and getting them committed.
Jon
