[Emc-users] Those ESR testing gizmo's on banggood?

[Gene Heskett]

Hi all;

They came in today, with zero assembly instructions, but there wasn't a 
very long list of things to do.

1. Strip all the craft paper off both sides of the plastic precut box 
parts.

2. Find some fresh 9 volt batteries, I had two for 2 kits.

3. Figure out how it mounts on the back panel and use the 4 shorter 
bolts, 4 tubular nylon standoffs and nuts to mount it, pull the battery 
connector out from under the back of it and attach it to a battery.

4. Arrange the 4 side/end parts, placing the side with the cutaway so it 
matches the zif sockets lever when its closed, and fasten the top/front 
panel on with the 4 longer screws and nuts.

5. Find a capacitor and form its leads to fit the zif socket, plug it in 
and close the socket.  One could plug test leads, not supplied, into the 
zip socket, in which case the leads ohmage will also be displayed added 
to the DUT's results I assume.

6. Press the button switch.  It will say testing for a few seconds as it 
displays the battery voltage to 3 digits + decimal, then report the ESR 
in xx.xx ohms format, % of power lost, and the microfarads of the 
capacitor, in my case nominally .32 ohms for the ESR, about a 1.5% power 
loss, and 2389 uf for a cap I've had for a couple years marked 2200uf.  
And it will shut itself off in 30 some seconds to go easy on the 
battery.

7. Wipe silly grin off face, it works1

One of them had broken the teeny little plastic tab that secures the lcd 
to the green backlighting panel, but a teeny drop of Go2/goop fixed that 
right up.  There are some holes and cut slots in the back where it looks 
like one might be able to cobble up some sort of a clamp to keep the 
battery restrained, but w/o any instructions my imagination wasn't 
working well enough to decipher that puzzle. Also a square hole in one 
of the side panels where leads soldered to the board could exit from. 
But for about 30 bucks delivered for 2 of them, I believe I got my 
money's worth.

Its supposed to be able to identify whatever, maximum of 3 leads, it is 
that you plug into the zif socket but I've not tested that yet.  So 
diodes, transistors, maybe even inductances can be measured.

I'll find out in the next days.
Cheers, Gene Heskett

It wasn't that cold when I was there for 6 months before turnkey, and a 
bout a year after as I was doing the portal door cctv maintenance after.

High 60's estimated.  And to around 90F when they had switched to 
generated power full time, a month or so before turnkey. Big 6 cylinder 
diesels, biggest IC engine piston I'd ever seen till then, nominally a 5 
gallon bucket for a piston. Top had a hole in it, some AH had left a 
wrench inside when the head was bolted down at the makers site.  I guess 
it started and ran with it hammering around in there for about 10 
minutes. That triple head and triple cylinder casting were, shall we 
say, beyond a simple resleeving rebuild.  No profit left in that bid.

But Dave, that would need someone in power to have common sense!

I don't have it handy, but I am dead certain there is a Murphy's Law 
about that which absolutely prevents it. :)

Cross posting to EMC-Developers

Dewey,

Thanks for that. I probably should have started this thread on the developer
list. I will test it tomorrow.

> Also, I cannot jog over linuxcncrsh ...

Updating the master branch for improved
joints-axes functionality necessitated changes to linuxcncrsh jogging to
support both axis coordinate jogging (TELEOP_MODE) and joint jogging (not
TELEOP_MODE).

In general, changes for the master branch are described in the "Updating
LinuxCNC" section of the devel docs:
http://linuxcnc.org/docs/devel/html/getting-started/updating-linuxcnc.html

Linuxcncrsh is specifically included at para 7.9 of:
http://linuxcnc.org/docs/devel/html/getting-started/updating-linuxcnc.html#_
linuxcncrsh

The linuxcncrsh man page has also been updated to some degree for jogging
methods:

http://linuxcnc.org/docs/devel/html/man/man1/linuxcncrsh.1.html

Because there are few users, the changes for linuxcncrsh have been lightly
tested.

Re: [Emc-users] LinuxCNC

Only half kidding; the power room of a Titan I missile site would just 
about do. 55 F year around. IIRC the measuring system needs about 4X the
resolution of the tolerance you need to hold. Concrete and steel have 
approx the same thermal coeff of expansion.


I like the idea of access to a major waterway. I really could not 
believe it when the contractor for the new sections of the Narrows bridge
opted to ship by truck. ( I90 Chicago to Tacoma)  Got held up for quite 
a while at the WA border while everyone fought of regs and paperwork.
My thought was the they had decent waterway all the way and basically 
could have lifted them off the ship ... or off a barge into place.

But then what do I know. Politics and logic are rarely in the same room. ;-)

Most interesting project.

That might still be a good idea, because it seems that such a machine

rolled steel sections seems like a likely solution.
There will be some tyre-creep, but the laser (or acoustic) feedback
could correct it.
I heard of a system where you have a microphone in each corner of the
room and a "clicker" that is localised in space by clever acoustic
processing.
The application was measuring accelerometer positions when
instrumenting a car or van body. If you have ever "walked" a Faro arm
round a van body you would know why the system seemed attractive.

Re: [Emc-users] Homing XYAY configuration

[Dewey Garrett]

(oops -- posted to wrong thread earlier)

linuxcncrsh (actually src/emc/usr_intf/emcrsh.cc)
has been updated to a *limited* extent for the
master branch with joints-axes updates.

The extent of updates has primarily been to
maintain the scripts that are used in the runtests
suite of tests.  These scripts are run on the
buildbot (for all supported operating systems) at
each new commit.

In src/emc/usr_intf/emcrsh.cc:setHome(), the code
for "Home All" (== -1) is rejected in both the
master branch AND 2.7.  The absence of this
particular functionality is likely indicative of
the limited usage of linuxcncrsh in the wild.

I've pushed a commit to add this "Home All"
capability and verified the runtests are still ok
on my test machine.

The commit, for the master branch only, is:
https://github.com/LinuxCNC/linuxcnc/commit/b3568fb9094b0075087242fc543c8db0d8e3ad40

#--
There may be other features available in guis
that are not implemented in linuxcncrsh.  If you
make changes and push them to the master branch of
git, it will be important to run the runtests
suite to ensure that the expected output of
existing test scripts is not altered since
alterations may cause test (and buildbot)
failures.

that are not implemented in linuxcncrsh.  If you
make changes to add missing features and push
them to the master branch of git, it will be
important to run the runtests suite to ensure
that the expected output of existing test scripts
is not altered since alterations may cause test
(and buildbot) failures.

Ref runtests scripts:

I jumped through the hoops of fire. It works.

Thanks for the patch and support.

[Emc-users] Homing XYAY configuration

[Eric H. Johnson]

All,

I am running Lcnc 2.8.0-pre1 in an XYAY configuration. I use the linuxcncrsh 
interface for my user interface. It is looking like there are additional 
commands that need to be supported.

Home all, for example, on axis runs differently than doing the same thing over 
linuxcncrsh. Also, I cannot jog over linuxcncrsh, but can with axis. MDI 
commands, and presumably gcode files do work over both interfaces.

It so happens I wrote linuxcncrsh. Are there additional commands that need to 
be supported?

Thanks,
Eric

Thanks,
Eric

I think the scheme (I had some of the old Yaskawa ServPack 
drives and motors once) is the C channel looks like A and B, 
but the phase relationship between them tells what 
electrical quadrant you are in.  So, immediately on 
power-up, the drive knows which coils to drive to move the 
motor.

Re: [Emc-users] Axis -> EMCMOT -> Yaskawa SMC-2000

[theman whosoldtheworld]

I think you have come solution: not use yaskawa controller at all ...
instead use Lcnc+mesa card and connect it to drive ... or use Lcnc and
customize rs422 mesa bord signal for your porpose or add some rs422 to your
pc linux and make your own program.
But the use is for sheet metal working in professional mode (big production
> 100 pcs) with "Z" or omega profile etc etc? In these case inform you
about these: Lcnc project is born for chip machines .. so all the necessary
trik into sheet metal working (Calculate the retraction, the angle of fold,
the positioning of the stopper etc etc) is out of scope. For shure you can
implement all these features in kinematics module + your ouwn program for
calculate these .. probabily in phyton ... and you can add these module
into axis Gui or other gui on Lcnc. If you are familiar with these
calculations, the only problem you will have is to create the interface ...
but I see that all the manufactorer start from mach3 or similar and realize
their own Gui interface.

As you see the rs422 comunication is a little part in these project.

That's odd;

Just a thought, but after you applied the patch, you did rebuild /
install? The patch applies in the working tree, but the build process
copies and renames axis.py (One of the last steps, I think).

Re: [Emc-users] MDI edit/UI question

[David Berndt]

I got no joy on this one, or I don't understand the expected result of the  
patch.


In 2.7.8 that I pulled/built a few months back. Changes appear to apply  
just fine, but when scrolling through the history list I can't press home,  
left, right, end, etc to begin edittng.


Turns out insert works, which I didn't know previously. I restored the  
pre-patch axis.py and tested again, insert works there as well, so no  
actual change. But having any key that lets me get into edit mode is all I  
really needed. The choice of insert seems a little dubious to me.

I've ran into this problem, too; best as I could see, it wasn't possible
to use the keys with that particular entry box, so I made a few
modifications to the axis.py script to give me left + right, home and
end keys. It seems to have worked fine for me, for > 6 months.
