cradek: not really
cradek: to busy building the boat, are you guys considering migrating to git ?
cradek: never used git, used svn quite a lot but my main problem with git has always been the lack of a central "authoritive" copy or server for a company that's a problem
yeah, we will have one that works that way.
cradek: head great things about the merge capabilities in git, but then again i'm also a bit scared of the idea of every developer having his/her own branch
cradek: makes me think of something one of my teachers told us first day working repositories "Branching is easy, merging is hard"
I think development will still be fairly linear, but sometimes we desperately need more...
we avoid big features/changes currently because if they take long, it causes great pain.
cradek: Also the last time I checked git only ran on linux, might not be a problem with emc though
git merge makes keeping up to date much easier.
there is git/windows now.
cradek: there is a google talk lecture my linux on git if I remember correctly
but yeah, not sure if anyone will use it.
cradek: i'll see if I can find it
I've seen it
he's an ass, but I won't judge git by that.
I ment to say "by linus" :Ð
yeah, he's arrogant, does not mean his not right, and I see his point for OSS projects
at first I avoided git because of his attitude - but that's a poor reason.
in any case, it's bound to be better than CVS :)
I'm sure that's true.
cradek: you might also want to consider perforce
can I put you down on the "in favor" side? the board is trying to at least get a basic opinion from all the active developers.
cradek: i'm in favor yes
cradek: From what I have heard, Perforce is supposed to be really good and it's free for OSS projects
perforce is not free software - I think it's not a good choice for us because of that.
cradek: but then again it's not OSS
IMO that's a show-stopper
cradek: It's good to keep it OSS imho, I've just gotten to used to giving in to pressure from spoiled devs :)
mshaver: what were your feelings about the big git switch? I don't remember if you were there for the big discussion at fest
cradek: I was around for the discussion but, "I don't have a dog in this race". I think that most projects have decided they want something more modern than cvs. Some early "switchers" went to svn. git came out a short while back, and I'd never heard of bzr until fest. I'm sure _any_ of these would be perfectly acceptable, and Jeff (as the release manager) probably has the "biggest dog in the race"!
I'm glad we waited past svn... :-)
yes jeff and I have done the most with releases.
I think a decision has been made, and you guys should stick to it, unless some other idea wins your support because of its merit. So far, no one has presented a convincing argument otherwise.
I doubt you'll lose any developers over this no matter which way you go.
My personal wish? Move the mailing list! :)
sf is slower lately, but that comes and goes
From SF to another server system. It just seems there are big delays from posting to receiving my own post back.
mshaver: yeah, sadly
mshaver: want to add your "in favor"/"opposed" to the list? http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?EMC2_Development
For example: You posted today that you may have made a mistake in your list of all committers. This was at 4:59 EDT. I don't think I've received the e-mail you are referencing with the list of "committers".
Wow. Only 27 commits! I need to hurry up and make some changes! I think I'll change all the whitespace! :)
Anyway, "In Favor".
indent --wrong-settings / cvs commit
while(1) indent --random-settings / cvs commit;
That'll get my stats up!
I did have it, just didn't read it closely enough, sorry. What you said, "For someone who is savvy enough to be contributing to a
free software project, this is just not going to be a hurdle", says it all.
anyway, going downstairs now to look at this cnc mill that I've got from Smithy for testing. I've got some work to do on it and I'm going to make a list of the parts I need! It will feel good to do real world stuff for a change!
thanks for sharing your thoughts
this isn't real?
cradek: Opinions are like... well let's just say everyone has them!
"those French. They have a different word for *Everything*!"
SWPadnos: It's not real unless you can get hurt doing it! Of course, if you count hurt feelings then I suppose it's real enough...
now I'm leaving!
err, I mean good night
To the docs maintainers: In the 20090516 Integrator's Manual, 31.4.2 Realtime Module (ClassicLadder), "The fastest that ClassicLadder can refresh the rungs is one *millisecond*." I think this should be *microsecond*, because...
...it is followed by "You can put it in a faster thread but it will not update any faster. If you put it in a slower [than] one microsecond thread then ClassicLadder will update the rungs slower. The current refresh rate will be displayed on the section display, it is rounded to microseconds."
Plus on my one-rung ladder, on a 1 millisecond servo thread, the CL display bounces around the 4-19 microsecond area.
anybody here who does isolation milling for circuit boards? on which hardware? what kind of precision (on the board) do you get?
morning, Spida i have made some boards on my mill using isolation routing, seemed to work reasonably well
[08:44:42] <pjm__> http://pjm.dyndns.org/cam/pcb_test.jpg
was one of my very early tests
can you tell me something about the dimensions of the lines/spaces?
the small pads with adjacent grounding pads are for 0805 smt
how many lines can you put parallel in one cm?
a few i'd imagine, the minimum line width is about 0.2mm
and the minimum isolation-space width?
depends on the voltage you're planning ;)
alex_jon1 is now known as alex_joni
alex_joni: of course, but if I am planning for something like 5V, I guess the performance of the machine is the limiting factor....
pjm thats some nice machining right there
what were you using for a spindle?
archivist: is that your page?
Valen1 that was with my dremel attachment!
a bit crappy i know
were those links meant to be there?
between the rows at the top
pjm__: how long do you use your tools? I heard they wear out pretty fast...
ah yeah i tend to just regrind them each time i think they are getting blunt
pjm__: how often is that? I heard something about once for each board...
depends on the tooling you use
Spida, no not mine
yeah i tend to grind up my own cutters for the pcb's
if you use carbide cutters/drills I think they are good for ~25k holes but they also need ~25k rpm
basically get a carbide drill, put it in the dremel, with the dremel running quite fast, put it on a grinding wheel and make a shallow angle taper
then grind a flat one side of the point
Valen1: 25k holes, but how long for milling?
how many circuit boards?
one, ten, hundred?
people drilling 25k holes aren typically milling their PCB's
Valen1 is now known as Valen

[Global Notice] Good Afternoon all, this coming Thursday (June 11th) we'll be pruning the Services databases, clearing out stale nicks and channels. To prevent your grouped nicks being dropped and to avoid disappointment, please make sure to IDENTIFY. More information can be found at http://bit.ly/10nqla
Thank you for using freenode and have a good day.
Spida: one of my efforts: http://media.unpythonic.net/emergent-files/sandbox/tqfpboard.jpg
Spida: in my experience, the tools last until I make an error and break them. perhaps someday I'll become careful enough to run a tool until it dulls, instead.
interesting how the cuts look raised in the pics (optical delusion)
jepler: how many lines do you get on 1cm?
Spida: inchland here .. I generally use a trace width and separation of 10mil, so the distance between two trace centers = 20mil ~ .5mm
(1mil = .001 inch = .0254mm)
if I recall correctly, the central package is a .8mm tqfp. I wouldn't enjoy soldering anything finer
it's quite easy actually even on finer
[12:34:09] <jepler> http://media.unpythonic.net/emergent-files/sandbox/tqfpboard-composite.jpg
[12:34:22] <Spida> http://www.spida.net/tmp/platinen/whirlygig-bottom.jpg
<- this is tqfp 144, 0.5mm
etched pcb, handsoldered.
how do you silkscreen it?
I had that done at f-l.de
jepler: ever used tips like the one on the right? http://www.curiousinventor.com/images/guides/smt/tips.jpg
thats some commercial service here.
does boards with a maximum of 100*160mm (in small parts, too) for 40 euros a piece...
jepler: I have one thats looks like that, but didn't try it yet...
aeh, that was for alex_joni
alex_joni: the tip I use is http://www.parts-express.com/pe/showdetl.cfm?Partnumber=372-127
1/32" conical tip
jepler: you need to try one with a bevel
alex_joni: perhaps so
it's soooo much easier to solder
you need solder paste
applies on all pads, then you stick the part ontop
and using the bevel tip you just run once over all pins
and it's done
if I apply too much solder, it ends up creating bridges, particularly between fine smd pads. how will solder paste not do the same?
jepler: the solder is inside the tip
there's a cavity where it gets collected
and it only "comes" out when it has sides to fuse on
you need a bit of skill to handle the angle and the speed for the tip though
if you go too slow then you get too much solder, and bridges
bbl, must go to work
I meant flux not paste
you can see at around 5:19 here: http://www.youtube.com/watch?v=3NN7UGWYmBY
jepler: I looked at my aluminum pile this morning and I have some plate that's about .25 x 2.7 x infinity. I also have some plate .5 x infinity x infinity. have you figured out what thickness you need for the motor mounts?
cradek_ is now known as cradek
infinity fits in a pile?
you want half? :-)
been pricing ally for a machined pile
is it high over there?
dropped a bit /me hopes it drops more
[13:07:56] <cradek> http://www.kitconet.com/charts/metals/base/spot-aluminum-5y-Large.gif
in the US, the time to stock up is now
looks like it
I wish I had spare cash at the moment
[13:09:21] <cradek> http://www.kitconet.com/charts/metals/base/lme-warehouse-aluminum-5y-Large.gif
wow, stockpiles are way up, maybe it will still drop more
where do you buy your .5 X infinity x infinity? ;)
skunkworks_: inifinity is relative to the ~ 1x2" parts we're planning to make
cradek: probably .25
I know some screw heads need to be counterbored - I wasn't sure what they would be.
you're right, I should make sure of the head dimension
I was thinking of the bearing thickness only
this table says head height .138 inches
so if the counterbore goes .15 inches, that leaves .10 inches
I Get mine from infinity^2 metal company. They extract the metal from black holes.
someone's trying to sound funny today
trying? I thought I was always annoyingly funny.
in my mind anyways.
cradek: does anything nice happen to the formula if you simplify tan(acos(x)) ?
also, does your formula assume R1 < R2?
I don't know, and I don't know
I doubt it assumes that
it would be nice if it could be simplified further
what trig identity am I missing?
tan(acos(x)) == sqrt(1 - x**2) / x
does that seems simpler?
[14:17:01] <skunkworks_> http://git.sympy.org/?p=sympy.git;a=commitdiff;h=334917603895aba3e9f7b7d2171afeaf9f4c0bcb
yeah that's the identity I was finally working out
it does come out the same for the few values of x I tried ;)
tan theta = sin theta / cos theta; sin theta = sqrt(1 - cos^2 theta)
other than zero, that's a good identity
added a camera shot of my derivation... http://timeguy.com/
would be cool if someone can simplify it
oh, was that the original problem
I would just use the calculator at sdp-si :)
is the intent to use toothed pulleys or flat?
when I did this, it was for V - doesn't matter though
I wanted the correct answer
toothed belts have specific lengths, so you have to fiddle with the separation to get it to work
I was designing a set of step pulleys and I wanted certain ratios and same c-c distance
ah - a different problem
(but mostly the same)
2*R1*(pi - acos((R1 - R2)/D) + D*(1 - (R1 - R2)**2/D**2)**(1/2)/(R1 - R2)) + 2*R2*(acos((R1 - R2)/D) - D*(1 - (R1 - R2)**2/D**2)**(1/2)/(R1 - R2))
(-2*R1**3*acos((R1 - R2)/D) + 2*R2**3*acos((R1 - R2)/D) - 6*R1*R2**2*acos((R1 - R2)/D) + 6*R2*R1**2*acos((R1 - R2)/D) + 2*D*R1**2*(D**(-2))**(1/2)*(2*R1*R2 + D**2 - R1**2 - R2**2)**(1/2) + 2*D*R2**2*(D**(-2))**(1/2)*(2*R1*R2 + D**2 - R1**2 - R2**2)**(1/2) - 4*D*R1*R2*(D**(-2))**(1/2)*(2*R1*R2 + D**2 - R1**2 - R2**2)**(1/2) - 4*pi*R2*R1**2 + 2*pi*R1*R2**2 + 2*pi*R1**3)/(-2*R1*R2 + R1**2 + R2**2)
hm, I don't care much for the "simplification"
but it has R2D2 in it
man, what a bummer. Simon and Garfunkel are playing on our anniversary
but they're playing in Sydney, Australia
For some reason I thought they where mortal enemys
I think they were for a long time
then they ran out of cash?
could be :)
jepler: Chocolate Chip Cookie Recipe?
SWPadnos: But if it had C3PO you could always metl it down for gold scrap
but I think he's just gold plated
Oh, then hook him up with Kathy Griffin and go on the gay/lesbian comedy circuit
do we know if it is even gold? it is a galaxy far far away..
skunkworks_: it should not surprise you to hear that this has been debated at length. http://boards.theforce.net/classic_trilogy/b10002/15044060/r15044297/
SWPadnos: In your cameras, are you streaming mpeg2?
SWPadnos: then what are you streamng?
the cameras take photos, those are downloaded, scaled, cropped, and placed on a server
then someone else takes the images and makes quicktime and flv files out of the stills
no still, video
I have no video cameras, and I have done no work with the live view modes on the still cameras
hence my answer - no streaming
I thought you did some very hi speed video cameras
the end product is a moving picture (video), but the source, and everything I deal with, is stills
and this is what you were working on when we were tlaking about gig switches and the like?
or 10GigE pipes?
how big is one still?
for MTV, they started at 3 MP
the cameras can do 12 MP
and we may have 100 cameras in the next rig
SWPadnos: do you have a sample from the mtv awards?
hmmmm, ke I'll take your word for it, but the numbers don't add up
framerate for the stills?
how about 48 of them: http://www.mtv.com/photos/2009-mtv-movie-awards-fashion-360/1611667/3945724/photo.jhtml
Jymmmm, one frame every few seconds, but maybe faster later
SWPadnos: very cool :)
yep, it worked out well
SWPadnos: how many cameras on the link?
this setup had 48 cameras
oh Isee them now, abut 8" apart?
geo01005: I don't understand it
15-3/8" or so :)
the last line is not simplified, and where did b come from?
Just one what of simplifying your equation, the second part assumes that (R1-R2) is equal to b and -(R1-R2) is -b
SWPadnos: And what did you do? Create the electronics to control and manipulate the cameras and storage?
I designed the trigger system (hardware and software), wrote all the scripts to capture and process the images, and put together the netwok to move all the data (12 computers on the truss, one server, plus several mac clients)
organizing that amount of data, in that environment, is a real pain
SWPadnos: You know, you could have made things similer just by using Barbie USB camera and a shake-n-bake oven
or Speak and Spell
there were plenty of Barbies arounf
somebod did a good job on hiding the cabling
cradek: Sorry I forgot to re-simplify, here is the result http://imagebin.org/51947
yep. that took quite a bit of time
the triangular truss helps a lot, we stuck some black wireway inside it
SWPadnos: Did you guys have to adj a camera or two during the shoot?
in what way?
no, not really
it might have been good to re-align at some point, but that process is a real pain
ok, I noticed one or two cameras were off a bit
hold your eyes on the cameras during a flick, you notice the position errors
I think the truss ended up being not-quite-circular, you can see the cameras weave around a little bit
if you look at the gap between the edge of frame and a camera, it changes a little
it was probably also not quite flat
usually, we try to hide the rig, so you wouldn't notice that kind of thing
in this case, they wanted to see it - it was part of the "look"
[Global Notice] Hi all! This coming Thursday (June 11th) we'll be pruning the Services database, removing expired nicks and channels.

I don't know why I did it, but the auto upgrade to ubuntu 9.04 seems to have gone smoothly
eric_unterhausen: on a non-emc2 machine?
from what to 9.04?
yes, on my desktop, 64 bit
it was 8.10 or something like that
that should be ok
I just booted up one of the power supply controllers, and it's running dapper
I'm debating whether to upgrade it to 8.04 or not
I have a hard time convincing myself to upgrade something like that
I guess I can still get emc2.3 for dapper, so the additional featuers of comp should be available
this is for one of the engineers to experiment with other things on
I have some control computers still running Redhat 9.something
so the UI and easy programming features are more important than having an identical system to the installed ones
does youtube work for you?
working here too now
[18:17:02] <alex_joni> http://www.youtube.com/watch?v=M8ijWbg_seI
alex_joni, probably like I cant get www.ab.com from here, silly routing problem somewhere
alex_joni: are the steppers setup in velocity mode?
skunkworks_: I think so
at least that's what he said
I'm hoping that's a mm machine
.005 is a pretty big FERROR in inches
SWPadnos, is the lathe running?
cradek has one running, correct?
I haven't applied power to it anywhere
and Kirk Wallace
for mine - a while. I have a lot of work to do this summer
of course :(
(then again: :) )
refit fodder 320379862655
wants too much money though
money is bad
I have no room for one either
so glad my machines are servo... that looks soooo slow
for one of the video shots I could tell from the sound that it was rapiding, but I couldn't tell what was moving
I want to get a bicycle-sized sandblasting cabinet
no room for that either
but if it's homing steppers to index, that's pretty neat.
to scale index even
cradek: what video?
[18:44:08] <archivist> http://www.youtube.com/watch?v=M8ijWbg_seI
izzat a deckel?
those are some robust sounding steppers anyway
looks like rapid is 10mm/sec
need a netflix account to keep yourself sane
I don't know what it is, but it looks stout
there is at least one other brand of mill that is configured like that
also, looks like he's done some updating to tkemc
interesting mention of touch screen,
* archivist hopes for info to be fed back
I am hoping to get my touchscreen to work, but the same can be said for my mill :)
ive downloaded a few things to try the touchscreen here but got no joy yet
EbiDK is now known as EbiDK|AWAY
archivist: I have the tkemc version somewhere
alex_joni, would be interesting to try, see if this screen works
hmm.. don't think I have the latest
[19:10:03] <EbiDK|AWAY> http://www.instructables.com/id/Birth-of-Man-Mixing-Board/
I'm a little curious how this story works but hey, cool mixer anyway :P
[19:10:10] <alex_joni> http://pastebin.ca/1454159
thanks alex_joni /me saving it and having a read
archivist_emc: might not hold those changes
I'll ask for a newer one
DEFAULT_LINEAR_VELOCITY: It's in [TRAJ] in configs/max/max.ini, and in [DISPLAY] in configs/sim/.axis.ini. Where should it be really?
mshaver, they do different things, so both may be necessary
I think in the DISPLAY section, it's used to set the initial position of a slider (can't remember the name of it at the moment)
SWPadnos: I'm not sure that's true
the TRAJ one doesn't do much iirc
it should be in [DISPLAY], and it's used for the default linear jogging speed
The Integrator Manual says DEFAULT_VELOCITY goes in [TRAJ], no mention of ANGULAR or LINEAR.
ANGULAR and LINEAR are probably AXIS specific
it's newer than the other GUIs
So, DEFAULT/MAX/MIN_ANGULAR/LINEAR_ACCELERATION/VELOCITY all go in [DISPLAY]?
Like the Integrator Manual says?
those are AXIS specific and go in the DISPLAY
Cool! Thanks! I was just looking for confirmation of this!
um. there are different meanings in DISPLAY vs TRAJ
I don't know that there is any reason for _ACCELERATION to be in DISPLAY, since (AFAIK) AXIS doesn't have any accel control
for _VELOCITY, the numbers in DISPLAY will define the top end of the various UI sliders
SWPadnos: Right, but I was looking for their "GUI meaning" so that Smithy's EZ-Trol would be consistent with AXIS.
whereas in TRAJ, those will be hard limits
there is no acceleration in display
OK, I was only really concerned with <something>_VELOCITY. SO the <something>_ACCELERATION ones go in [TRAJ]? That's what I would expect.
I guess I was trying to say that it's not either/or
you may want both DISPLAY and TRAJ MAX_VELOCITY settings
(I'm not sure why, but you might :) )
Right. They could be in both? Need to find this out for the manual to be right.
yes, they're different limits
in the DISPLAY section, the MAX_VEL will set the top end of the "speed limit" slider in AXIS (whatever it's called)
in the TRAJ section, it will set the (constant, read at startup only) overall TP velocity limit
Yes, it's just that these params aren't qualified with LINEAR or ANGULAR in the description of [TRAJ] in the Integrators Manual.
So it's not the exact same string of chars
I'm not sure, but I think they were split out because angular and linear axes use different units
THey should be, but it's not described in the manual that way.
just an observation....
I don't know if I'm more reliable than the manual. I suspect I'm not :)
BJT-Work, while I think about it look at todays log KimK left a documentation comment
SWPadnos: "To thine own self be true, and it must follow, as the night the day, thou canst not then be false to any man."
modern translation: "be confident, and eventually you'll convince others you're right"
or something like that :)
Or... If you can't dazzle them with brilliance, baffle them with bullshit.
* BJT-Work goes home to play with the tractor
I'd feel like an idiot if my price list didn't allow copy/paste
SWPadnos: Seems strange... pay you all that money only for 48 photos =)
SWPadnos: not the paying you part, as much as the only 48 photos part.
there were 59 people, two takes each, each take was 48 photos
it's a lot more than 48 photos
SWPadnos: Well, I mean 48 videos
they had to take some down because the traffic borked their site
got an URL?
[20:23:37] <SWPadnos> http://www.mtv.com/photos/2009-mtv-movie-awards-fashion-360/1611667/3945724/photo.jhtml

lets slashdot it :D
tou and 100000 others
I don't know if you noticed, but you can zoom in on those images
it says powered by Nikon, not SWPadnos
yeah, strange, isn't it
SWPadnos: I noticed, and was looking for you mug
I'm in the blue tent, wearing a white shirt
I'm sure you can't see me well in any of them
I'll have to loo again
I think you'll only catch my white-clad arm
SWPadnos: I can see you
[20:27:31] <alex_joni> http://www.mtv.com/photos/2009-mtv-movie-awards-fashion-360/1611667/3947240/photo.jhtml
oh, I think I stuck my head out for Megan Fox :)
6th foto from the end
same here: http://www.mtv.com/photos/2009-mtv-movie-awards-fashion-360/1611667/3947609/photo.jhtml
SWPadnos: So, how many sample Nikon's were you able to keep?
I have 11 D300's here
but no D700
seen the new canon 5d mkII ?
should probably have been just as good
not for this
the shutter lags aren't consistent enough
that's a pretty neat effect
hmm.. if you say ;)
I like the through network live preview part
is it the people or clothes that (are supposed to) make this interesting?
SWPadnos: Waas the post procesing live?
in this case, both
cradek: must be the combination
each taken by it's own are boring :D
looks like people I don't know, wearing slightly odd clothes :-)
Jymmmm, the post processing was done in < 90 seconds for each effect
actually, the time from capture to finished flv and quicktimes was < 90 seconds
you can see camera lag hand rotating this one http://www.mtv.com/photos/2009-mtv-movie-awards-fashion-360/1611667/3947609/photo.jhtml
look at her face and hands
she didn't move - I'd bet any artifacts are from jpeg compression or something happening to the rig
she was one of the last people we shot
SWPadnos: Ah, ok. So you grabbed the image via USB, did you have hubs in the scafolding?
we had computers
4 cameras per computer
ethernet to the server
archivist: if you look closely you'll see the cameras aren't perfectly aligned (hard to do in field condition, so the fotos might be slightly up/down)
her expression changes
(look at the line of cameras while rotating)
who painstakingly blocked out all the computer cases?
I'm sure the rig got bumped several times, so the alignment was likely a little off by the time she came around
you can see the computers
they're small black boxes
her face size changes
covered in black
in the jpegs
normally, we would have done a better job with the stabilization and color/exposure matching
but they actually wanted it to look a little "raw"
also, we'd normally have more than a 1.2MPixel image, and it sure as hell wouldn't be jpeg compressed to hell
SWPadnos: How did you deal with banding (not sure if that's the right term
not sure what you mena
oh, lens correction?
um, I can't remember the term... it's when the outside is semi fish eyed
yep, that's it
we didn't deal with it
oh, cause that is a real bich dealing with it manually
if you figure out the right incantations, imagemagick can do it for you
I took shots of a 100yo factory that was being destryed of one wal that was 200 foot or so long, and moved the camera in 10-15ft inrements to get a mural image, turned out icky
watch that for 5 minutes
[Global Notice] Hi all! This coming Thursday (June 11th) we'll be pruning the Services database, removing expired nicks and channels. Please make sure you IDENTIFY to NickServ to avoid disappointment. A few more of these notices will be sent in the next 24-36 hours - but please do visit http://bit.ly/10nqla
for more information. #freenode is here to help! Thank you for using freenode and have a good evening!
there are some filters that do nice barrel distortion based on focal length and focus distance
(even from EXIF)
I could just look at the source images instead :)
there are even a few at full res
yeah, but it doesn't constantly spin like that :P
You can see the treelace is off in the link alex_joni gave
it's too bad they didn't use the second take of that one - she jumped for that one
Jymmmm, you can see the minor position and rotation corrections in that flv as well
SWPadnos: are the white square reflecters or lights?
just for looks
oh, not IR ?
are they lit?
yes, that's why they show up as qhite squares
heh that link reminds me of those music boxes with the dancing ballet
SWPadnos: Nice job btw!!!
SWPadnos: If that's not licensed, you could set that up at a carnical and make some money
cruise ships, etc
it seemed to be a big hit - there are half a dozen new jobs out for bid
Jymmmm, yep, loads of places to use something like that
SWPadnos: you mean to do what you did?
you need to do HDTV on those cameras next
err.. HD videos I mean
to go use that system, or another just like it
yeah, that would be nice
lots more data though :)
SWPadnos: do you have a non compete clause?
I don't own any of that equipment, and it would cost me about $200k to get it
not sure about the Dx00 but the canon can only shoot to CF HD vids
so non-compete is meaningless
yes, the Nikons that do video also will only shoot to CF, AFAIK
maybe Jymmmm wants to sponsor one
SWPadnos: I think you could make your money back easily and you could get sponsorship
SWPadnos: I'm sure Nikon would love to get new things out like that
I don't have a non-compete, but it would be pretty shitty of me to go and compete with my customer
assuming they pay all those large invoices :)
SWPadnos: From what youve mentioned to me, they were pretty bitchy, or was that soemone else?
alex_joni, is that a registration only or ? /me cannot read german
they tend to be fickle, but since there's a big success at the moment, they seem more willing to pay up on time
archivist: crap, thought you can see the pic
let me imagebin it
[20:57:13] <alex_joni> http://imagebin.org/51980
that I can see :)
still german :P
good night alex
I am trying to run EMC on Jaunty, I know that it is not supported on Jaunty but I am hoping somebody can help me anyway.
I have compiled a rtai kernel and installed rtai 3.7 and the rtai tests work great.
I might can some.
I can compile emc both 2.3.1 and trunk as run in place but I always get the same error.
when trying to run no errors compiling
RTAPI: ERROR: failed to map shmem
HAL: ERROR: could not open shared memory
halcmd: hal_init() failed: -9
NOTE: 'rtapi' kernel module must be loaded
do you have enough memory
I have 1 MB installed in machine
sorry that is 1GB opps
heh slight difference
I have emc2 running on jaunty here.
can you run it as root (sudo)?
yes it loads when I run sudo ./scripts/emc from my install folder
ok. I had the same problem.
You need both of the following lines in /etc/security/limits.conf
* soft memlock 10240 #EMC2
* hard memlock 20480 #EMC2
I had the hard memlock as I had already seen documentation on that, but needed the soft memlock as well.
jepler pointed me to a page on the wiki which mentioned that way at the bottom, but I can't find the page right now...
Yes I to added the hard memlock entry but did not see anything about the soft memlock
Ah, here it is: http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?RtaiSteps
that did the trick for me.
do I need to restart after the change?
never mind I just read the page that say to log out and then back in
yeah, just a logout works
I'll be back later. let me know if it works
Its working thanks a lot
Anyone here familiar with classicladder, specifically the one-button touch off example documented on the wiki?
[23:14:37] <sliptonic> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?ClassicLadderExamples#Single_button_probe_touchoff
do you have a specific question about it?
I had it working well under 2.2. After upgrading to 2.3 it stopped working. I've renamed the pin as described in the wiki but it's still not working.
ok, interesting. can you post your HAL file(s)?
The probe works and it sets the touch-off correctly but doesn't retract.
Also, it only runs one time.
sounds like the two (r) resets in the bottom rung aren't getting executed
or M3 isn't finishing
That's what I was thinking too. I don't know much about classicladder. How do I troubleshoot it?
you can watch it execute - the GUI is animated if the realtime stuff is running when you start it
I think the AXIS machine menu has a classicladder entry
Here's my jgro.hal http://pastebin.com/d310b98b8
there's got to be more, that one doesn't load CL
ok. you should definitely take a look at the CL GUI while running through a touch-off cycle
if you can post your CL file, that could also help (though it won't help me, I'm not a CL expert ;) )
where is the cl file?
it should be in the same directory as the hal files
Would it have a .clp extension?
Touch_OFF_Button.clp - from your custom.hal file
Here tis: http://pastebin.com/m11962f7f
not that it's human-readable :)
No wonder I never bothered to look deeper.
I'm not sure I have a PC running that I can load this with
(and like I said, I'm not an expert with CL)
When I ran the touch off cycle I got pink lines up to the %M1 and %T0 in the bottom section.
Then an error about 'probe tribed during non MDI move'.
oh, interesting. Did you get that error before?
or did it just not finish (and refuse to repeat)
I'd never seen the error before. I just re-ran it and got the same pink lines but no error. Just halted and refused to run again.
The error might have been caused by me trying to manually trip the probe.
could be. there are various error conditions that probing looks for (or optionally not, depending on the G-code you use)
it'll take me a minute to set up a sim config that I can load this ladder in
np. Any help at all is great.
My timer symbol in the gui is different than what is documented on the wiki. Mine has 2 connectors on either side. Could that mean anything?
it sure could
but I don't know what .)
I couldn't find a way in the GUI to produce the symbol shown and assumed it was done with 2.2. A number of the variable names changed like %Q2 -> CLoutB2 so I didn't think much about it.
those should be OK, as long as you change any references in the HAL files
the block labeled "TM" in the editor has only two connections
Mine has 4 labled E,C,D,R. The vertical from %B1 is connecting to E.
well, I'm sure there's someone who knows just what changed. unfortunately that person isn't me
This config was copied from the files on cnczone in 2.2 and not manually entered.
yep, I'm not sure what happened between 2.2 and 2.3 (except what I read on the wiki)
Ahh. What I have is what you get if you use 'old timer block'
oh wait, the wiki tells you what to do :)
connect the C pin to the E pin ;)
[23:54:24] <SWPadnos> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?UPDATING#Classicladder_changes
Do I just do that with a vertical connector? Doesn't seem to have an effect.
you may need to connect a short horizontal and a vertical
I don't know that you can have a vertical directly on the pins
Whoa! It did something. Let me retry this.
Sweet! That did it.
