anyone tell me how to set pin 4 7 and 14 on the parallel always to high.... and is it possible to use 4 pins for step sequence or will I need to edit and recompile emc to get it to use a 4 pin sequence instead of step and direction 2 pin method?
you can use 4 pins
see the HAL manual - there are about 14 different "step types", including several that use 4 pins
to set certain parport pins always high, link them (in HAL) to a signal that is always high
ty very much
did not know where to start to look and the hal files I have not checked
something like "net high parport.0.pin-04-out parport.0.pin-07-out" then "sets high 1"
for the stepping type, you'll see most hal files do "loadrt stepgen step_type=0,0,0" you will want to change the zeros to some other number

BigJohnT: as if that means anything to you guys ;)
good to know they have express slot serial cards now that I don't need one anymore
BigJohnT: doesn't work tho
apparently, it's no better than a $5 USB thing
there is two USB to serial things that work for my PLC communications, the cheap ones don't work
the one I have is fairly expensive, but it's USB->serial->parallel
hmm Keyspan is the one I use
I forget the other one at the moment
Well,... This sucks ^_^

SWPadnos: Hey, did I tell ya that I got vmserver2 installed?
yep, I think you did
SWPadnos: Well, I had vBox previously, so I wasn't sure
oh - vmserver - maybe not :)
SWPadnos: Yeah, the console is web based. So you can Remote Consolle into a VM via a browser plugin
a 25mb plugin, but if you connect once locally, you have it for when on the road.
SWPadnos: You can even restrict VM access to per person.
hmmm. I should clean one of my desks
then I can put acomputer there
then I can actually migrate over to the new workstationn
then I can mess with vmware/vbox ;)
then I can clean the other desk, then the floor, then the closet
then I can rip out the walls and actually get the network wiring installed correctly
vbox has that dual license, and the OpenSource one has no USB
and *then* it'll be tax time again
The other lic is Personal use only, and has USB
vmware-server is free and supports USB just fine
SWPadnos: When I got it installed (vmserver2), I cp a vm from the mac, it asked if I moved or copied it, and started up perfectly
yep. that's the major draw for me
I've thought about setting up a computer with a minimal OS and VMs on their own partitions
SWPadnos: BTW... It's running on that crappiertop under ubuntu 8.04.1 AMD64 w/ 3GB
upgrade OS, no problem
JymmmEMC: /ALWAYS/ say you moved it, lol
JymmmEMC: atleast, if you want to keep it's networking settings
fragalot: Nope, copy it
I just upgraded my laptop - it's got a 200G drive and 4G RAM now
I may look into CPU and video upgrades at some point
cpu upgrades on it?! yeow
JymmmEMC: I have custom network settings for the VM's, if i say I copied it, I lose those,.. thats why i always make it think i moved them.
it still lasts close to 2 hours on a charge (actually doing things)
that's part of the reason why it's so big - it's actually pretty modular
SWPadnos: gotcha. So, when you installing that paraport module =)
bah - who needs it? :)
it does have expresscard though, so if there's a parport card available I could
SWPadnos: Um, I can think of one person who did =)
I just tested the RT kernel - it's actually not too bad on the base thread - maybe 15000 latency
the servo thread had gazillions of ns though
SWPadnos: you play with git yet?
[14:30:45] <anonimasu> http://unit.aist.go.jp/amri/group/finemfg/English/research/Microfactory/CPT2002.pdf
not too much, but some
SWPadnos: cool, I might hit you up as some of it I dont get
me either ;)
anonimasu: me likes.
I think it's very cool :)
micro machines :)
SWPadnos: Well, since I'm popping my cherry on revision control as it is, it's not helping much. But I watched a couple videos to try and understand the feature set, and really liked the distributed aspect as well as "via email" too
git is somewhat confusing, even for people who have used version control before
at least for this person who has
SWPadnos: I'm hoping that my lack of knowledge of cvs/svn will help
SWPadnos: But once I "get it", I can use a handful of gmail (and other) email accounts as a backup repository =)
I haven't seen anything on that, but you may be right
SWPadnos: apt-cache search git- and you
[14:40:53] <anonimasu> http://www.physikinstrumente.com/en/products/prdetail.php?sortnr=300710
SWPadnos: apt-cache search git- and you'll see a an email module
SWPadnos: a highly structured email, but still.
what's the package called exactly?
(not on Linux ATM)
ah - git-email
SWPadnos: git-email - fast, scalable, distributed revision control system (email add-on)
I don't think that allows you to use an email account as a repo. it just makes emailing patches and things easier
SWPadnos: You can even use git as a front end to subverison with checkin/outs to it
that would be cool to use for SLS machine
[14:44:45] <fragalot> http://www.collegehumor.com/video:1831461
nice utility. I'm still pretty sure you can't use an email account to hold a repository
SWPadnos: I can try =)
SWPadnos: But, either way, the whole 2.6 kernel takes up 1.5GB, and gmail now allows 20MB attachements, so split sound slike a winner
renz0r is now known as renesis
[14:54:19] <JymmmEMC> http://www.kernel.org/pub/software/scm/git/docs/git-mailinfo.html
SWPadnos: I can dream at least =)
you can email patches around, but they still get put into a repository of some sort - the emails themselves aren't the repo
SWPadnos: I understnad.
so there are tools to help you format patches to send, and to extract patches from emails, but that doesn't give you a repo in an email account
unless I'm wrong :)
SWPadnos: Well, you have to be able to get/send them, and maybe there is a checkout via email
(so to speak)
SWPadnos: Either way, I still like the idea of email -offsite
SWPadnos: If the datacenter blows up, I still have the latest
SWPadnos: The offsite backups, was the one issue I had to deal with still. This MIGHT work
it's shower time for me. bbl
SWPadnos: lol (bastard)
SWPadnos: Even in irc, your sarcasim still comes through =)

sweet surface finish on aluminum, EMC rocks
i tried to make the "Demo" pawn that comes with it, but the 0.5mm in feed was too much for my little steppers, they stalled out and i got to learn all about homing.
i think the max these steppers are good for is about 0.3mm in feed at a time
dunno if anybody cared, but i felt the need to tell SOMEONE, the excitement is overwhelming
and surprisingly not many people appreciate how exciting it is.... i tried to explain why this is so cool to a few people and they just looked at me and started messaging on their cell phone
dareposte: sounds good, take some pics if you can
it's always nice to hear positive responses from people
[16:31:29] <dareposte> http://www.youtube.com/watch?v=6Cr9SjoEmYk
thats parting a piece of stock
and here's turning just a cylinder to see how it works: http://www.youtube.com/watch?v=Ckg_XqZU7f8
yes i would have to say that EMC has exceeded my expectations so far, I had heard it wasn't so good for lathes, but I now beg to differ
heh, glad you feel that way
do you plan to do threading?
dareposte: pretty heavy facing cuts there
almost a rapid
yeah i was just jogging it
seeing if it would stall or not
the sound for the cylinder "finish cut" seems wrong
like it's cutting rough
alex_joni: I do plan to do threading, but I haven't hooked my index pulse up yet since I've relocated it
jmkasunich: noticed that too :/
Hmm wonder what I can do about that
maybe a new insert?
the parting sounds nice tho
that one is getting pretty old
dareposte: could help.. yes :p
i didn't have any coolant on it either, or lube
just dry cut on aluminum
yeah, that was what I was gonna suggest
about halfway through the parting cut it got a squirt of wd40
it sounds "dry" if that makes any sense
WD40 is excellent for aluminum
oh it was bone dry for sure
what spindle speed was that?
cooling + open case == win
i've heard crisco works as well as anything for aluminum, from an old time machinist at work
WD is easier
1000 RPM * 1" dia * pi / 12 = 261 sfpm, fine for carbide
but at that speed I bet the aluminum chip softens enough that it wants to stick to the tool
my text says 250-300sfm for aluminum, so thats what i was shooting for
the "dry" sound is the chip sticking, then being ripped off
I bet some WD would help the chip flow off the tool smoother
i will try that next time i fire it up, i've shut it down now to get the E-stop circuit and the spindle index pulse wired back in again
fragalot: what do you mean by "open case", you lost me there
I think he means that if you use flood coolant on a machine without guards, you will get wet ;-)
dareposte: nothing to keep the... exactly
i have a sliding door i've built for it
speaking of which - you should figure out something to protect your screws from chips and such
yeah that's high on the list too, some sheet metal guards for the screws
its by no means "completed", but i couldn't wait any longer to see if it would work or not :)
I understand that completely ;-)
the half enclosure it's in right now is fully sealed, and I have a front panel with sliding door built on some drawer slides that will go on it once it's ready for coolant
:D I'd do the exact same
right now, the control circuits and all are just slopped on the bench underneath, so I need to get them out of the way before I even consider something wet in the area
thanks for the critique on the dry cut, it should help next time. the surface finish looked good though once it was done, i wasn't going to complain
consider something wet in the area.. so the metal chips are no issue for the baords? :p
my usual result when I have that sound is a rough finish - tiny bits of aluminum stuck to the surface
dareposte: nice vid, congrats
tomp: thank you, EMC made it all possible :)
get yourself some tap magic aluminum (with the cinnamon scent) - it makes a very nice finish on aluminum
[16:54:09] <fragalot> http://nl.youtube.com/watch?v=-a_ipqppf0k&feature=related
now, THAT is a lathe ^_^
spray/dab it on as needed - it shouldn't splatter too much
I don't like how close the handwheel is to the giant chuck tho :p
SWPadnos: Is that different from the regular tap magic?
fragalot: it almost looks like a giant piece of foam or something?
concrete it says
gotte be hell on the lathe ways
Speaking of lathes....
How much does it cost to get a small toolmaking lathe?
And how stupid would it be to try using one with no experience with metal-lathing?
spasticteapot: that is a tough question
spasticteapot: gotta start somewhere
I started out metal lathing when i was.. 13 i think
how much does a used car cost?
jmkasunich: too much?
jmkasunich: Depends on how much car you want.
same with lathes
fragalot: Luxury vehciles are quite cheap these days...
dareposte, yes. the aluminum formula is different
lol at the anti-chatter methods in that concrete lathe video
there was an old one that I don't know much about (it was carcinogenic so it was removed from the market)
but the new one works really well for milling or turning
The minimum priceI I saw paid for a 2003 Lexus IS300 was the same as the maximum paid for a 1993 Geo Metro.
(And I didn't look very hard.)
who the hell would pay 13K for _any_ metro?
especially a 15 year old one
especially a 15 year old one?
jmkasunich: you mean the guy standing on the tool post
It was a pink convertible metro.
yeah, and the crescent wrenches, and such
And 60mph from a tuned XFI variant was VERY appealing when gas hit $5/gallon on the west coast.
18mpg from a V6 luxmobile...wasn't.
jmkasunich: and people standing on the wrench (bit later)
understood - but still, 13K for a POS is nuts
spasticteapot: you do know that out here it's $10/gallon.. and has been for quite some time?
around here a 15 year old metro would probably be falling apart
jmkasunich: they wouldn't even last that long
fragalot: Yes, but you live in the real world. I live in the USA.
spasticteapot: :D 5 weeks till doomsday!
I just got a funny error message from youtube

I wanted to figure out what it said

I have what I hope is an easy-peasy first project for a lathe:
Fancy brass goggles.
lathe.. goggles.. in one piece?
Partially because I like the steampunk look, partially because I want some safety goggles I don't look like a doofus in, and mostly because, once I get the hang of making them, I can sell them for mucho dinero on the interwebs.
[17:06:05] <spasticteapot> http://www.brassgoggles.co.uk/images/MikeSTBrassGoggles.jpg
i was thinking i'd put mine to work making those bronze or zinc .50BMG projectiles you see selling for $5usd /ea
ah like that
that looks awesome... but.. the.. no doofus part,.... :p
I need to get an old Norton motorcycle to go with those.
Regardless....they look pretty easy.
All I need is to find some brass stock that does not cost more than the moon.
* spasticteapot curses the high price of copper.
you too huh
y'know what I want?
something i can wear OVER my normal glasses
that's not a full face shield
[17:08:41] <dareposte> http://www.riflebarrels.com/images/50bullets.jpg
<--- outta be a piece of cake with a cnc :)
these guys need to learn about chipbreaking: http://www.youtube.com/watch?v=Uans3Q_Mb94&feature=related
jmkasunich: naaah :;p
jmkasunich: it's more fun when it digs into the toolbit and rips the machine apart
fragalot: Get some perscription goggles.
* spasticteapot is nearsighted, so he can usually just take his off to work.
spasticteapot: too pricey. And I can't find those.. all i have is swimming goggles, and sunglasses
[17:10:42] <spasticteapot> http://www.flickr.com/photos/mikest/247903419/in/set-1552863/
How did he cut these is what I'm wondering.
Both the pattern, and the method of cutting.
* spasticteapot is confused as to how you would do this.
first make the goggles on a lathe,.. then take them out, and do the rear shape with a mill?
a 4-axis lathe would work too
y'know what the fun part is of talking to less experienced people? You can say the tool chatter is decorative, and intentional. :p
Here's one of those 50bmg projectiles next to a standard .308 cartridge: http://www.tenxbullets.com/Images/50+308w-web.jpg
I'm still a bit confused as to how you'd go about sloping them.
cnc mill with a rotary would be easiest
Assuming I don't have one of those?
spasticteapot: can you fit a drill to the toolholder? :p
dareposte: That thing is enormous.
Has anyone ever built a handgun that fires one?
yes they have, i've seen a picture
anonimasu: I prefer the smaller round than the .50... that barret one,.. .472 or something ?
and shortly thereafter they broke their wrist
I have thought about shoulder-mounted recoil compensation systems.
[17:16:55] <dareposte> http://airbornecombatengineer.typepad.com/photos/weapons_fireams/thunder50diagonalace.jpg
The best way I could think of to do it is to connect all axis (axes?) of movement to pneumatic pistons.
there's the one i've seen
dareposte: thats insane, lol
I've heard its not so effective though, as it really needs a minimum of 30" of barrel length to get up to speed
[17:18:19] <spasticteapot> http://airbornecombatengineer.typepad.com/airborne_combat_engineer/2005/01/the_maadi_griff.html
here's a dangerous looking fellow holding it... http://californiahuntingtoday.com/hogblog/wp-content/uploads/2007/02/tripleaction50bmg1.jpg
anonimasu: i meant the .416
it's smaller, lighter, but the range is like a third longer...
I'd prefer the .338 lapua honestly, but the market for .50bmg lathe turned projectiles is pretty good
the .416 is also excellent
I mean.. it's supersonic for over 2500 yards,.. and still effective up to 3250
I like thunder 50BMG handgun is optimal.
can it be chambered in a remington 700?
if you're talking about the .416 barrett, then oddly enough it was developed because some states banned the .50bmg as being too dangerous
the irony is that the new one is effective further, smaller, and more efficient :)
just goes to show, if we can't do it, we'll find another, better way
Getting back to the subject of goggles....
heh... sorry spasticteapot
Is there a way to produce the curve on the back of them without substantial milling skill (or a CNC machine)?
[17:22:23] <fragalot> http://www.collegehumor.com/video:1800939
hahah thats awesome.
spasticteapot: hand tools?
to make those goggles you need either a cnc mill with rotary table, live tooling and a 4 axis lathe, or a shaper of some sort
or just lay it out and scribe lines, get it pretty close with a manual mill, then file it to final dimension
dareposte: some proper manual labor could do the trick too
And a lot of filing.
hacksaw or bandsaw would also work if you are careful and patient
yeah, that'd work
belt sander all the way if you're lazy and don't mind burning your fingers over and over :p
or slap a dremel and encoder on your lathe
ststoppI love the goggles :)
well, belt sander works too
(sorry saw that was alread mentioned
wh a 5 axis machine?
5axis would work
oh 4 axis lathe ;)
well, a 3 axis mill will do..
Let's assume that I just have access to a cheap lathe and a drill press.
Because I suck.
spasticteapot: I don't even have access to those things for personal use,.........
I'd mark out holes..
then dril drill drill..
or use a bandsaw(or a hacksaw)
and cut out the contours
I'd cut it with my dremel
sand it down with the dremel
and file it to shape..
lots of perussian blue :p
do some minor filing, and then hand sand it down all the way :)
or wathever it's name is
(19:27:05) fragalot: Naib: if you'll design me an USB, or ethernet, (or SATA or SCSI or whatever :p just no serial or parallel port) 3 axis stepper controller that works with EMC2 (linuxcnc.org)
(19:27:23) Naib: deal
well, it's kindof his job,.. Don't think he was as serious as I was tho :(
the asimos are so fluid they almost look animated..
[17:28:41] <fragalot> http://www.prognar.com/PalinFlowChart.jpg
dareposte: yeah! :D it's pretty amazing isn't it
all those tiny servos in there.. it's madness... like... SPARTAAAA
yeah i'm having a hard time believing its all "real"
but i guess technically they are just replaying a programmed series, so they don't have to balance or think any other than remember joint positions from memory
I'd like to kick it over.
what happens ;)
anonimasu: They have programming for that.
Pretty sophisticated stuff.
you wanna see something a bit more worrisome on the robotic front? Boston dynamics has a fully autonomous balancing robotic dog, that runs on a chainsaw motor
I bet the engineers at honda dont kick as hard as I do.
i think there's a video somewhere hang on
[17:35:44] <dareposte> http://www.youtube.com/watch?v=W1czBcnX1Ww
old stuff already :p
that's hilarious.... a chainsaw motor :p
they have much cooler stuff going on ;)
so it can't sneak up on you
or you run away 'cos you think it's a bunch of bees
that'd be a cool place to work at
just temporary until the 30-year nuclear silent battery gets installed
we need fuelcells badly
damn dude you just can't knock that thing over o.0
lol even on ice it doesn't go all the way down
yeah i am thoroughly impressed by it
* anonimasu nods
I mean.. it's carrying 340lb arround meanwhile
and going up a snowbank
lol it can even bounce forward :p
its only a matter of time before they put a gun on it
[17:39:33] <fragalot> http://www.youtube.com/watch?v=YgrR-h7AXjY&watch_response
boston dynamics are looking for robotics engineers..
[17:40:17] <dareposte> http://www.youtube.com/watch?v=VXJZVZFRFJc&NR=1
I want the job at the bottom. http://www.bostondynamics.com/content/sec.php?section=jobs
cad cam cae.. and huydralics..
anonimasu: you wanna be a copyright?
I dont give a crap, about that..
sounds like a neat job :p
I'd go for the 2nd last one
mainly because it doesn't mention "experience" anywhere without the word "or" infront of it
well, I just lack the degree -_-
me too, .. at the moment
2 more years >.>
I've got 5 -_-
resume submitted :-D
* fragalot points a water jet at dareposte
well, there's still lots of fun stuff left in robotics.
hey once we get one person on the inside...
convert it over to run on EMC, so all the further developments are open sourced :)
i'd like to get some work on that new human exo skeleton they're using, saw a video of some GI testing it and he did a few hundred chinups before he got bored
[17:48:50] <dareposte> http://www.youtube.com/watch?v=h2jlIRKswnQ
I always wondered how long it'd take to make that
it is also awaiting the 30 year life nuclear battery to become really useful
all it needs is fingers.
dareposte: what output does that battery give anyways
been a while since i've heard about it
1000 volts at 10,000 amps
oh i don't think it actually exists
i was just fantasizing...
it's beeing researched...
no doubt i'm sure it is, but i haven't heard anything about any real life prototypes that have been around
ideally it would be about the size of a lantern battery, put out from 100-400 vdc at 100 amps, for a minimum life of 30 years. and cost under $20
i'd buy two
apparently those things have existed since the 50's,.. and have an effeciency of (hold on) 0.7 to 5%
but only last 10yr
hey that would be sufficient
[18:07:15] <alex_joni> http://www.youtube.com/watch?v=qFCam2GFyT8&feature=user
I think somebody got bored
oh its a kit
I have a paper on the exoskeletong
on the huydralics
I love the stuff they talk about how exoskeletons are less vunerable the human in battle..
I think they are forgetting that if you shoot into a single joint..
or a single board.
or damn a bus connector it's all over.
that's the greatest typo ever
or a bus cable..
which one of them
i make alot :p
i think the idea would be that its so strong it can also carry ballistic armor
21:08 < anonimasu> I have a paper on the exoskeletong
anonimasu: they said "battle"
anonimasu: they didn't say in a gunfight
fragalot: oh, other sources do ;)
anonimasu: also, if you add armor plating to that,..
it doesn't really care that much about weight, does it
I think it's more usefull in packaging facilities to help load the trucks
i bet it would be pretty useful for the heavy machine gunner too
or under my christmas tree.
fragalot: I know about the armor it's just that the general public seems to think that they are solid :p
haulin that thing around
hauling some really heavy guns with one is cool :p
add a backpack helicopter to that exoskeleton
okay now that is just outrageous
what are you guys on about... the robo dog??
fullblown "come on in" exoskeleton
that appears to work
have you seen him?
sounds like warhammer :p
yes i seen that before too
the bummer of the idea is that it can't be used in 'part'... like if you just need one strong arm to lift a half ton or so, you still need the skeletal support all the way to the ground
well, down to your hips should be fine..
if you can get it light enough
and likewise as anonimasu pointed out, if a single leg joint or support structure failed then the whole thing becomes pretty useless
likewise you can have armor
but F = A*p for huydralics
an interesting reliability engineering challenge for sure, especially in "battle" conditions
and at very high loads that becomes fun..
like if you add armor to it ;)
just wrap it in kevlar
did that suit use hydraulics? I didn't look that closely but it looked like it had servos
they user huydralics
electric-servohuydralics actually :)
fancy valves ;)
pretty good response for hydraulics
it's pretty damn awesome
I've been trying to buy thoose valves they use for work..
hydraulic push pull actuators
but i think the "gentle touch" part of the skeleton requires experience
but they are too much $$$$$
wouldn't want to give it a handshake
it has a CLAW
FEAR THE CLAW
[18:27:35] <anonimasu> http://www.servovalve.com/
lets say that thing takes a hit
just step out of it :/
the knee and hip joints look like rotary something or other, not push pull
yeah or it crushes you and twists in ways the real body isn't supposed to...
or the 3000 psi hydraulic line explodes and cuts part of your leg off :)
that's my concern ;)
they usually dont explode.
but well, extreme flexing make them break
and the pressure might be way higher then your system pressure when that happens
dareposte: as if getting a .50 in your hip is a better alternative :p
i personally don't like either alternative

those look like hydraulics again
basically a gain loop with your body movements as the input it looks like
quote: I give all credit for the exosuit invention to Robert Heinlein because of his explanation and description in the book Starship Troopers.
that seems to happen a lot... the creative authors and artists come up with awesome ideas and describe them, but don't have the skills to bring them to life. Then a group of scientists or engineers who otherwise might not have thought of it read the book and make it happen
asimov ftw ;)
yeah prime example
cradek: you around?
anyway, I thought I'd let you know I got the tool post working on this lathe using classicladder.
CL does seem like a good tool once you get used to whole "ladder logic" thing.
It's just rather different for a "chip oriented" person!
I've spent the last couple days finishing the wiring and estop stuff. Now I need to finish the machine logic.
Can someone explain what I need to do to run AXIS in lathe mode?
put LATHE=1 in the DISPLAY section of the ini
I've seen the LATHE=1 thing (or true I don't remember)
but it seems not to like have only 2 AXIS sections
check out the sim/lathe sample config that runs on your version
even if I say there are only 2 axes in the traj section
the way you specify X,Z has changed
X and Z are 0 and 2, so you have to do something I don't know to get rid of Y
pretty sure you need AXES=3, for a reason that's obscure but spelled out in the docs
ok, I'll look at the latest sim/lathe
are you running trunk or 2.2?
do you know where in the docs? TRUNK
about a day or two old
[19:40:10] <cradek> http://linuxcnc.org/docs/devel/html/config_ini_config.html#sub:%5BTRAJ%5D-section
in trunk I think you say [TRAJ]AXES=3 and then have [AXIS_0] and [AXIS_2]
that with [DISPLAY]LATHE=1 should give you a useful display
and make sure COORDINATES = X Z maybe
OK, that may not be a combination I've tried! ;)
Cool! I'll try this here shortly!
look at an example first though. I don't know what I'm talking about :)
Also, I'm writing a post to emc-users wondering if there's a way to use a HAL pin to display an operator message (that will work in auto mode).
sure - do something like hal_manualtoolchange
SWPadnos: this goes without saying for both of us!
that has a couple of HAL pins, and it pops up a message for the operator to change tools
mshaver: what is the original goal that you hope to solve with that?
I've actually never looked at that
I have some error conditions that I would like to have cause a program pause or abort (done with HALUI) and display an explanatory message
e.g. tool post fails to index correctly, or VFD fault detected
or a couple of AC cycles lost, but not enough to crash the PC
seems like halui could issue one of a list of previously defined operator messages, in a similar way to how it does mdi
so you're looking for the HAL equivalent of (msg, "oops")
yes, and yes
[HALUI]MESSAGE = "you didn't frob the dingle"
I was thinking of extending HALUI in exactly that way
=> halui.message-01, bit
go for it
the mdi stuff is very close to that already
Oh, you mean actually do this myself?
What a novel idea!
<mshaver> I was thinking of extending HALUI in exactly that way
maybe I didn't understand these words properly? :-)
Oh you understood them!
It's just that I am full of good intentions...
do you get operator messages simultaneously on all guis?
I've never messed with this.
but sometimes lacking in the execution dept.
I think it's an NML message, so I would say yes
I should look at that
I think there are 'messages' and 'errors' that (may) get displayed differently, but I'm not sure
some of the GUIs have a "message area" for things that don't need acknowledgement
I'm fixing to go home to MD from MI tomorrow and I might have some more "in front of the PC time"
to do this.
but I wanted to know if I had overlooked some other obvious way of doing this
not that I see
at least I wouldn't be re-inventing an existing function
ok, I'll proceed!
letting ladder and/or hal report errors in english really isn't there afaik
make it so
for a small number of messages, a somewhat modified hal_manualtoolchange might be a better alternative
I don't agree
that already has some logic to display a dialog, allow its dismissal, etc.
I'll look at that too, I assume it';s a HAL component with built in messages?
halui doesn't do anything with an acutal GUI at the moment
one of the jobs of the emc gui is to show messages and errors
it has one message "insert tool %d and press done" or similar
/does a /ForceNickChange skunkworksemc JeanLukePicard
* JymmmEMC does a /ForceNickChange skunkworksemc JeanLukePicard
HALUI isn't a GUI though, so it isn't necessarily a good place to start
AFAIK, the only way to display operator messages is with new NML messages
(assuming you want all the GUIs to do it)
I'm talking out my ass if I pretend to know how messages work
me too, but I wasn't going to say
I'll study up on it.
SWPadnos: OH! Is that cradek's photo you posted earlier?
"So let it be written. So let it be done."
me too, hungry
the above line _really_ works well on my wife...
mshaver: "me too, hungry" ???
meaning, "I'll be back later as well! I'm hungry and desire to eat something now."
mshaver: If that works on your wife, does she have a sister?
I've never really developed a knck for this instant messaging shorthand...
mshaver: such as?
such as bbl and things like that
I get it! Someone has surprised you with a barbecue!
but.... it's in the shape of a bunny with a pancake on it's head!
thus the WTF
anyway, now to eat, soon to try lathe mode in AXIS - back in a little while!
Does anyone here know where I can buy brass pipe that's 1.5" in diameter with 1/4" walls?
spasticteapot: where are you from?
I wasn't aware that brass tube required a permit or had any regulations....
I thought it was like toothbrushes and kitty litter, not uranium.
then I'm out of ideas :)
it's a weapon!
spasticteapot: why cant you just buy it?
www.onlinemetals.com or something?
anonimasu: I was asking WHERE I could buy it.
Most places max out at 0.12"
you might have trouble getting them in very short lenghts
1/4 wall is pretty thick for a 1.5" tube, I think
ah tube.. that's probably harder then solid stock
I don't need strength.
It's for goggles.
Well, solid stock should be much easier to buy
* spasticteapot needs to learn how to use a lathe.
and probalby cheaper
I might just be able to use some plate on the end of a piece of much thinner tube.
Anyone here know where to get dichroic glass?
hmm.. solder it togther?
* spasticteapot is very good at soldering things.
Still...dichroic glass, anyone?
it looks like you can get bronze in 1.5/.25 tube, but not brass (at least Mcmaster doesn't have that)
Bronze is not as shiny.
Speaking of which, can anyone recommend a good coating for copper to keep it from oxidizing?
I've tried spray polyurethane, but it ends up all rubbery.
And it ruins the shiny finish.
in soviet russia
shiny finish ruins YOU
toastydeath: Well, THAT was helpful....

when building the latest CVS -trunk i recived the following errors, Error in latexParagraphs: You should not mix title layouts with normal ones.
I think you need another package - something like tetex-extras or similar
(I believe that error is due to a missing document template)
yea hardy, ill take a look thx
spasticteapot: i think you're sposed to use lacquer
sure. I hope I remembered the right answer :)
fenn: What sort?
spasticteapot: myself, i'm a fan of paste wax (furniture polish)
Paste wax works on copper?
seems like it ought to
try 'copper and Brass sales' (thuysen)
i use it for steel and iron all the time
brush it on with a stiff acid brush, let dry, then buff with a paper towel
it won't last forever, but hey that's what brasso is for right?
[20:47:04] <tomp> http://www.copperandbrass.com/cnb/index.htm
for brass tube
haha googling for brass brought up lots of places but some were 'bras' :)
SWPadnos, that worked
added it to the wiki for others
does any one have any good info on tuning servo drives?
there is a bit on the wiki, and lots more on the web
it really varies from machine to machine and person to person
so i have found out lol, realy just wanna know basic what i am looking for when performing the tuning as such then i can take it from there
what kinds of drives do you have? what kind of equipment do you have (scope, meter ...)? what kind of experience do you have?
(not that I can help much if you answer, but those are the kinds of things that change what you should do :) )
right now i have a samsung servo motor and drive on a 4th axis, the drive its self has a auto tune to set its own loop
with machine its self it has the old drive and motors still which only have tuning pot so EMC will have to fully tune thoes drives at moment just having play with 4th axis to get idea of tuning before i fit the control onto the rest of the machine
sorry - dunno about that hardware, and I've got to run.
good luck with that ;)
spasticteapot: I think the flat plate on a thin tube has a lot going for it
I suggest you calculate the weight of the thick walled version, and decide if you want that resting on your nose/eyesockets, before you spend $ and time
SWPadnos, np cya
I'm trying to find dichroic filter glass.
some specific color?
Whatever looks the coolest.
crotchetyGuy is now known as crotchet
A couple days ago, upon being prompted by the little orange indicator, I installed an rtai kernel upgrade on my 8.04 system (added EMC2 with the install script).
Now, when I run-in-place I get "can't load rtaihal, file exists".
are you sure it was an upgrade of the rtai kernel?
Sure enough, right after booting, a bunch of rtai kernel modules are already loaded.
I look at the GRUB menu and it's -16 rtai
seems like everybody and his brother has had problems like that, but we've been assuming (in the absence of reliable info) that the problem was an ubuntu generic kernel upgrade
that's the only choice I've got
that is an important piece of the puzzle that we haven't had till now
well, i've got it! anything you'd like to know?
unfortunately I don't know much about it beyond that
alex_joni or maybe jepler would know more
I didn't know they had rebuilt the RT kernel lately
I haven't tried rmmodding the stuff that's pre-insmodded for me yet
interestingly, I have the choice of installing rtai kernels and such from within synaptic
all that's currently installed (apt wise) is the modules I think
the RT kernel and EMC2 packages were just updated due to a previous build error on x64
sure, once the EMC repository is added to the list, synaptic can manage EMC packages just like ubuntu ones
ok, so that explains the update to the RT kernel
now, why is it resulting in people having modules loaded at boot?
are you using m5i20 cards?
seb used the kernel firmware loading mechanism (hotplug and friends) in an attempt to be more "linuxy"
the damned OS is detecting the 5i20 card at boot time and trying to load its firmware
treating it like a piece of computer hardware, instead of a device dedicated to an individual program
yep, I get some messages about that
that stuff _should_ be loaded at EMC runtime, not boot time
I think they're in dmesg
I think the rtai modules are getting loaded because of a dependency chain - the 5i20 results in the driver being loaded, which depends on something, which depends on something else, which depends on RTAI modules
so modprobe in its annoyingly helpfull way cluelessly loads it all
so, maybe I should look around in dmesg, and /var/log/messages?
and see what gives?
spasticteapot: Does Edmund Scientific have dichroic glass?
var/log/messages is the same as dmesg
ah, didn't know that
dmesg is the in-ram kernel buffer, /var/log/messages is the file that it eventually gets written to
the in memory version obiously starts no sooner than the last reboot, and may start later than that if the buffer got full
the file version can be very long
OK, I wonder if there's a way to say, "ignore this hardware please"
there might be
but I don't know
I thought there was some udev or modules.aliases-foo to do that
I was never very thrilled about the hotplug based approach
or to not try to re-load the modules and firmware in the emc script
IMO its a bug, but I don't know what the best workaround or solution is
KimK: I'll look.
for most users, it isn't a bug
for users with a 5i20 installed it is
once the correct firmware has been installed in /lib/firmware, it's a good way of getting the FPGA programmed early on
"early on" as in at boot time?
there may be a bug because the firmware gets loaded and the module does too, which is a problem for us
that is too fscking early IMO
the 5i20 is _anything_ I/O
it's hardware, it's supposed to work this way. But it's not very convenient for me as I want to change the fpga image from time to time
but for most people, it's hostmot2 or hostmot or <whatever_they've_made IO
that means what it is gonna be shouldn't get decided until I invoke a program that uses it
what it has to be is dependent on what it's physically connected to
well, we've had this argument before, and I lost
for most people, that will not change often, if at all
it is kind of application specific hardware, not a shared resource
like a disk or sound card
I don't particularly like the request_firmware method either, but I think it has merit for many users
but regardless of the philosophy, there is a problem in the implementation if ANYTHING other than the firmware load is happening at boot tome
yes, that is definitely a problem (maybe a bug, maybe a philosophical problem with the way EMC uses modules)
you mean the rtai modules getting loaded?
I agree with Matt's view - it is application specific hardware, not a sound card
sure, so it may as well get programmed with that application firmware early on
most people won't change its use on the fly
(with EMC anyway)
you and I are different ;)
(from the others, as well as each other )
all people would be able to use it if the firmware was loaded at EMC runtime
Not that I don't enjoy a good philosophy discussion, but...
but you want a workaround
what do you think I should do?
lsmod and paste the top of the list here
yea, sort of...
crap, might be more than just the top
pastebin the whole thing
usually EMC related modules are at the top of the list cause they're loaded when EMC runs and removed later
OK, give me a minute it's on another system, but it's net connected
but if they're loaded at boot they could be 40 lines down
near the top
So if I were working out the bugs for two different machines (servo mill and stepper lathe, say) both using 5i20 (5i22?) and I had two different "anything" external setups on the bench, and I went back and forth from time to time, there would be a lot of rebooting?
pastebin the whole list anyway
back in a moment with a link to it!
or at least, there shouldn't be
there will be a lot of manipulation of symlinks in some system firmware directory
but you _should_ be able to load either firmware without rebooting
IMO anything that makes you reboot your system is evil
17:45:54 up 104 days, 20:30, 5 users, load average: 0.70, 0.49, 0.53
that should be normal......
17:41:25 up 50 days, 21:12, 5 users, load average: 2.23, 2.07, 2.02
likewise that - that is my 3-in-1 machine, that runs seperate EMC configs for mill and lathe mode
I've switched many times since the last reboot
Thanks, glad to hear of minimum rebooting. BTW, I've not been paying attention, any news on 5i22? (hostmot2?)
seb is doing ongoing work on it
I haven't been paying much attention
I should, since I have a card and want to convert my machine from software stepping one of these days
does he post a blog? or should we monitor CVS?
[21:55:43] <jmkasunich> http://cvs.linuxcnc.org/cgi-bin/cvsweb.cgi/emc2/src/hal/drivers/mesa-hostmot2/
there is a TODO file in there with some of his notes to himself
or just ask on the emc-developers list
dmesg right after boot: http://www.mattshaver.com/dmesg.txt
also a README
lsmod right after boot: http://www.mattshaver.com/lsmod.txt
trying to run emc: http://www.mattshaver.com/emcrun.txt
hmm, nothing 5i20 related in lsmod
jmkasunich: Thanks, I'll keep checking it from time to time
I don't know where I saw that
I wonder if the module is loaded, loads the firmware, then unloads itself, leaving behind the RTAI stuff?
it doesn't print anything if that's the case
"bad image file", what is that?
the popup image?
is dmesg the same stuff that's echoed to the screen during boot up?
yep, sorry about the bad image
I'm not sure how closely they match
I think some of the earliest screen stuff might not make it into dmesg
does it run if you try it a second time?
I wonder where else I could look?
check /etc/rc2.d, and see if realtime is in there
before I recompiled I was getting "mismatch 531 vs 533" or something like that
hold on, I'll look
rtai_fifos and rtai_sem show 0 under "used by"
you should be able to rmmod them
sudo /etc/init.d realtime stop should take care of it
or halrun -U
that should then make rtai_sched have zero, and you can rmmod that
and finally rmmod rtai_hal
or do what SWPadnos says, and save a lot of typing
or rmmod rtai_fifos rtai_sem rtai_sched rtai_hal (order is important ;) )
OK, going to try this - back in a moment | 2
as an experiment, you might want to physically remove the 5i20, reboot, and lsmod to confirm that with the card not there, the rtai modules do NOT get loaded
that's what the check in rc2.d is for - maybe there's S##realtime or something
right now we're assuming that the 5i20 is getting detected and causing this, it would be good to test that assumption
One more quick Q about recent issues: If I install (reinstall?) from the EMC2 ISO (not Ubuntu+EMC2script), will updater offer updates for EMC2, RTAI kernel, (other?) and if so should I allow them?
updater will offer updates for every installed package
yes, using either install method, the updater will show available updates
allowing them (or turning off the updater) is a personal choice
I generally do, FWIW
I typically accept all updates
OK. But for the time being, there are issues with Ubuntu+script, correct?
there is one issue, which is easily worked around
the issue is that the RT kernel isn't marked as the default after the install
when Ubuntu updates the generic kernel, it tends to put the generic kernel at the top of the boot list instead of the RT kernel
the answer is to edit /boot/grub/menu.lst
before you reboot, after an update of the generic kernel
you can move the RT kernel above the automagic kernels list, and it should end up as default for a long time (even after an RT kernel update, so you'd have to manually edit again)
and whatever is at the top of the boot list is the default?
you can also uninstall the generic kernel once you're satisfied that the RT kernel works
there is actually a place in the file where you can specify a number
it's usually zero, which is top of list
then you'll only get updates for the RT kernel, and the most recent will generally be the default
OK, thank you both. mshaver back yet?
I don't see him. surprising that he didn't connect on the EMC box :)
Oh, and what was the name of that other (competing?) RT kernel project?
there are a few
Xenomai was the one I was trying to recall. Any of them likely to eventually replace RTAI?
SWPadnos: it does work the 2nd time
emc clears out the preloaded modules
the runscript cleans up after the apparent "failed run"
so, I guess that's the workaround!
or add halrun -U to some startup script ;)
that'd work too!
so, I think I was going to try AXIS lathe mode when all this came up. I think that's what I'll do now...
heh - enjoy :)
Thanks for your help. Back in a few minutes...
