[Emc-users] LCNC TED Talk style

[Sven Wesley]

Friends!

I've been asked to do a 25 min catchy speech for approx 100 super skilled
developers on a tech conference. They want to break the standard
What-you-can-do-with-this-cool-framework lectures and show something
completely different.

I'm thinking, I should have a few really awesome LinuxCNC videos running
during the presentation. I have a few on my own machines, but I would like
to show them that this is something you can run on your Pi or any other
small board computer. Please help me with some nice links!

Robots? There is at least one nice CNC welder out there.

I am going to emphasize how simple the setup is for a small desktop
machine, and how you can grow your machine with GPIO cards etc.

What more should I address?

And another: https://www.youtube.com/watch?v=nSbgQOF7OUU

That video doesn't show the "behind the scenes" stuff, but the system is
controlled by LinuxCNC running custom HAL files (no g-code, just joystick
control and a PyVCP panel for homing, etc).

Well, my 11x36 Sheldon is about ready to help me fit a new barrel on old
meat in the pot. Bertho Stultiens much improved version of the hm2_rpsi
driver is issueing commands to the 7i90 at 41.666 MHz write speeds, and
reading the results flawlessly at 25 MHz. That last kernel change Bertho
suggested is working very well indeed. As are my jogging dials and the
gui addtitions that show what they are doing.

Next I need to enlarge the tooling mix, more tool holders for the
Phase-II QC post, and maybe get a tooling grinder, and make a few more
accessories like a backend spider. The best I could do today is a video
of it running the lathe-pawn.ngc program cutting air. Beginning with a
tour of the controls, featureing an rpi-3b, a Mesa-7i90 card you can
almost see because its well hidden under 3 of the Mesa 7i42-TA's which
put surge protections and noise filtering for the 7i90 into play in
addition to supplying a decent place to connect all the wires.

I am fairly happy with how it runs now, and its now time to tool it up
and put it to work.

When is this thing scheduled to take place?

As in how much time do I have to shoot it with my semi-hidef Sony digital
Handi-cam, which does 720x480, and edit it into something that is not
sleep inducing? And giving me time to add CSS to the spindle speed in
this program, which would show better than the fixed 200 rpms its doing
now. And for cutting air, other speeds could be upped too. This would
be a good excuse to further fine tune the MAXVELS etc in LinuxCNC.

Oh, you've got to at least flash some of Stuart Stevenson's
videos from the old MPM Cincinnatti 5-axis machines.
https://www.youtube.com/watch?v=Nn1bJ3YAQdI&t=21s
https://www.youtube.com/watch?v=mxxdq6y8z8M
Stuart may have some more he can recommend. There's at
least one more that I couldn't find, where the head moves
out toward the camera, and everybody in the room leans back
in their chairs.

Sam Sokolik (there are two of them, father and son) have
some big machines and posted various videos of them doing
stuff. But, I couldn't find those on you tube - he goes by
skunkworksinc
on youtube.

RUGBOT!!! :D That is so nerdy I must show it!
And of course Chris' jukebox for the finale. :)
Anyone with a Raspberry or a Beagle? Would be perfect to show the wide
range. Think Raspberry CNC and the Stuart's monster.

What is the most complex code in the code base. I want to point out that
this really is some hardcore stuff. The people I'm talking to are really
good programmers so I want to give them some weird stuff. :)

I manufacture the CRAMPS board that adds 6 stepper drivers
and some heater FETs to the Beagle Bone for 3D printer
setups. All the brilliant stuff was done by Charles
Steinkuehler, especially mating the step generator and PWM
functions running on the Bone's PRU processor to a real-time
HAL component that runs on the ARM.

I'm not sure of complexity, but Robert Ellenberg's new
trajectory planner is VERY well thought out (Hell he got a
PhD out of it!) and is one of the biggest improvements in
LinuxCNC is the last few years. He gave a talk at one of
the Machinekit meets describing all the intricacies, and I
was barely able to follow the general concept.

Jon,

I would love to show a video or photos of the Beagle setup, do you have any?

Can someone please point me the to Robert's trajectory planner? If he got a
PhD out of it, the CEO for the conference will pee his pants of joy.

Oh, you should contact Matt Shaver. We worked on an aborted
project to weld pipes in situ. If we had the Beagle Bone, I
think the project would have flown. I believe he has some
videos of it working. He wrote a looped G-code program in
LinuxCNC that performed all the trig to make the welding
torch follow the saddle shape of the seam.
It was all under NDAs, but since the project died, and the
company that wanted to make it no longer exists, the NDAs
may be considered null. I have no idea if he will feel free
to release anything, but it is worth a try. If you don't
know how to contact him, I can do it.

No, but I believe Charles Steinkuehler does have some
videos. He would certainly know.

> Can someone please point me the to Robert's trajectory

His trajectory planner is certainly in Machinekit, and I
BELIEVE it has also been put into the latest LinuxCNC distros.
I am not an expert in this area of the code, but I THINK
this is where it is :
src/emc/tp/blendmath.c
and
spherical_arc.c

tp.c also includes the include files for the above, so these
functions must be part of the trajectory planner.

I guess I could get some pics of my CRAMPS test fixture with
the Beagle Bone. Not sure that would really interest anybody.

I also have drivers on an ARM processor but it is located together with the power electronics on a separate card. Ordinary motor and stepper I have done but are in the process redesigning the card and are still not happy with the software. Real time computer I am still thinking about but have seen BBB, raspberry and Cort-M*.

Amazing.

[Ralph Stirling]

I don't believe Robert Ellenberg's PhD thesis was related to
his LinuxCNC motion planner work. His thesis title is:
"A Stability-Estimator to Unify Humanoid Locomotion: Walking,
Stair-Climbing and Ladder-Climbing"

The link to it is:
https://idea.library.drexel.edu/islandora/object/idea%3A4538/datastream/OBJ/download/A_Stability-Estimator_to_Unify_Humanoid_Locomotion.pdf

My recollection is that Tormach paid him to work on the motion
planner (for both LinuxCNC and Machinekit). I could be wrong,
but perhaps he will pop in here and give the definitive answer.

Certainly no one today would get a Phd for writing a CNC controller. But I
would not be surprised at all if he did not need to do a considerable
amount of work involving motion planning if he was working with statically
unstable walking robots.

Likely some of that work found it's way in to a CNC motion planner. The
logic involved is the same no matter the application. You build a
trajectory line through space then chop the line in time at the control
period and then "magic" happens and you end up with joint rates.

If you look at the vita attached to the thesis, you will see that he
lists the work he did for LinuxCNC.

Yes, I can believe that his thesis did not come directly out
of LinuxCNC, but I think there WAS some tie-in. There may
have been some mathematical problems that he solved for one
of these projects that was helpful in the other.

The basic TP problem with the old EMC was lookahead, and
that was the problem that Robert tackled. A general
solution to executing a series of moves as fast as possible
while always obeying velocity and acceleration limits. I
can see why similar problems might come up in any kind of
motion system that makes complex movements.

> There's quite a big difference in the academic world when you can claim a
PhD or not. My wife has a PhD in Medicine from Karolinska in Sweden. It
took 5½ years and required 4 published articles, at the same time you write
one article for a technical degree and it takes 3 years. For sure you can
write many articles under your PhD studies and they can include a broad
spectra of issues. If he used LinuxCNC to prove ideas they are a part of
his PhD.
But there's no need for us to guess about it. I'll ask him directly. :)

The Tormach web site was very nice video. All their stuff in Linux CNC based.
Here is a demo where they cut steel. To me the most impressive part is where
they tap a hole on steel in about 2 seconds.

There is quite a loot of video from people selling turn-key systems

Hi Sven,
here is short video of a art project of one of my students, Maria
Manske:

https://vimeo.com/148933185

The six axes are controlled by a BBB and LinuxCNC.

See you
Florian

i replied direct to dave, so the user list didnt see this

it maybe of use for the talk

hi dave
maybe it was

while we're at it
rudy de prez's paper may be interesting

and the antenna array using linuxcnc
....i didnt find it yet :-(
