libatk1.0-0 violations..... im scared.. i llove livux...but :-! what to do now.... its good to have friends...:)
"violations"? what did it say
Error: Dependancy is not saisfiable:libatk1.0-0
im a linux screw-be
with a pretty honkin' linux box too.... i can MAKe g-code for 5 axis stuff and EMC2 can run it if i get a little help from my friends.... post processor's are LawrnenceG's fortee
i'm using ubuntu 6.06 lts right now & have libatk1.0-0 installed ( tho the version is listed by Synaptic as 'l1.11.4-0ubuntu1' ) so it >is< satisfiable (somehow)
where did you find that ver??
try using Synaptic to install that file, and see what it reports ( it wont screw up anything to try, as Synaptic will stop shy of destroying your system....afik )
i found it by opening Synaptic ( Syetm"admin|Synaptic then searching for 'libatk'
i found it by opening Synaptic ( Syetm|admin|Synaptic then searching for 'libatk'
i likely have universe & multiverse enabled as sources
as repositories and yes i also have 'restricted' allowed
then try 'update', then search
bbl... wife's home .... its fightin' time.... ;0
again, best o luck ;)
it ain't luck....it's concentrated power and skill....if all i went in was with luck i'd have been outta dodge 5 yrs ago
still a downward spiral WITH altitude........ i can still save ME...and THE KIDS.....
what is it one runs to update library paths!?!?
sheesh, windoz solution initiated :).
dang, do 'man ldconfig'
DO NO SUCH THING
i man (man ldconfig)
(board soldering... see?)
i wish i didn't.
I wonder if Cadence will import part libraries from eagle
I was doing a design rules check on my part, and it gave me 3 error messages
one for "documents", one for "and", and one for "settings" in my path
David Ball - Riding With Private Malone(1).mp3.. find that
cadance.... tell me if you get it to work...
I'm almost there
heh, I had "strata" of sawdust under the chute on my table saw - I was alternating between cutting tempered hardboard (dark brown) and pine
cleaning up the pile - it had stripes, like sandstone at a road cut
but the board layout software rejected all the parts I made myself
she will spark up TOO... be carefull
there have been reports of explosions, but they are incredibly difficult unless you are forcing small particulates into the air
I've been forcing them into my shopvac
no boom yet
that would be a thump in your case
the guy that did the 'chips' penguin, his mail list has been talking about using a mechanism for a satellite dish for an A B head. but they never mention the part, any ideas? sounds like a cheap way to get a 'knucklehead'
i can lite up coffee whithener... dont fack with FINE "particulate"... as i call it.. and dont BLOW UP
yeah, but those things have gotten fairly rare
it's a dc motor with a big gear
he has a nice web site
just a motor & worm? oh, i thought it was some azimuth, other thingy, thingy
the biggest explosion I ever was close to was a 8oz planter's peanut can full of acetylene
acet-oxy mix I bet
(if it was actually an explosion and not just poof
not really, it was a pilot light
it shook the building, probably just a very energetic poof
pure acet (or any other fuel gas not mixed with air or oxy) just burns fast - foomp, not boom
hell... ive been 100 m from a full 18' x 24' drift.... PLUG YOUR EARS AND STAYBACK......
we had these torches that would leak acetylene so there was a pilot light and you didn't have to strike each time
there probably was a little oxy in there
but it was a yellow flame
not bench top stuff
dmess: you get enough of it, and even a foomp turns into a boom
it was digiing 8 feet into the direction of the blast..
over-break.... 3-5 ft was sweet enuf for us.... straight DOWM
that doesn't compare to a 8 ounce planter's peanut can
thru HARD ROCK... PLS
anybody can do a large explosion with a large explosive
thats on top of an 8' drill and break
I wonder if Trek keeps good enough records that they would be able to figure out I used to work there
we worke small and personal..... its mine in the morning
im sure your name is good enuf to be where it should be...
i recall.... find me a 2nd
proto or whatever...
id ride an old fat one these days......
I was just reading some history of the company, talk about revisionism, whew
not nice to say that about her
for some reason they call this building a barn: http://blog.guykawasaki.com/2007/08/my-visit-to-tre.html
it is a steel pole building that was attached to a concrete building that you can see in the background
seen it 2 x in the last 2 yrs... it sucks for us who have to make the changes
I was in the concrete block half of the building when the peanut can blew, both buildings shook
was it a stress member??
the peanut can
I think someone had it to put water in
but it was upside down on the table
just add water http://www.cannon-mania.com/bigbang.htm
I have a cannon, never used it
it's funny having worked for a company that some people care enough about to keep history

[13:23:40] <BigJohnT> http://i47.photobucket.com/albums/f163/johnplctech/Plasma%20Cutter/Plasma012.jpg
I have a micro switch on the floating head of my plasma cutter that is connected to probe in
my plan was to use this for both touch off on plasma cutting and for centerpunching
I've ran into a problem with centerpunching with a spring punch
I get an error if I try to go in the same direction as the touch off
any thoughts on this?
I don't recall the exact verbiage but something like this probe all ready tripped
for example when I touch off with the torch and go back up all works as expected
ah.. you can't move while the probe is tripped
not down only up
you need to unhook it from HAL if you want that
or use one of the other probe moves
SWPLinux: won't those halt immediately?
as the probe is hit?
yes, but no error :)
* BigJohnT looking at them
ok I see a G38.3 gives you no error thanks SWPLinux
sure. it also won't move though, so ...
(if the probe is tripped)
you can also probe looking for the input to deactivate
with the centerpunch I need to find the surface then move 3/4" down more
so g38.<xx> move up until probe not tripped
then move down until tripped
if it's not tripped, the first one will perform no motion
so the second one exits me from the probe routine?
the first one insures the punch is clear
the second brings the punch to the surface
though it seems you'd be making all sorts of bad marks if the punch were dragging around on the surface :)
I move it up after the punch
is the switch getting stuck, or is it just that you may try to punch with the torch near the work?
so all I need to do is move to my spot then G38.3 till I touch then G91z-0.75
no the switch is good
and the torch is off
ok. I guess I don't understand why you'd get the error them
after probing the switch is still closed and I try to g91z-.75 and I get and error
do I need to g91z.25 then g91z-1
to reset the probe?
I didn't have much time last night to try different options...
I'm not sure how to get around that actually. when the probe input is tripped, you don't want to move down, or you'll break it
hmmm, not in my case...
actually, I have no time now to help out - gotta go get breakfast before getting on a plane
see you later
thanks and have a safe trip
I have tried to use emc2 for a couple of years, but always the problem is hardware and unbuntu 6.06 live cd aren't compatable
anything going on to update to a later version?
my guess is if your hardware is so old that ubuntu won't work it's not going to get better...
no the problem is the hardware is newer than 6.06
however, on one machine I just changed the hard drive and all was ok and on another I had to change the video card and then all was ok
I see its the other way around
there's an 8.04 liveCD, but it isn't "official" yet: http://www.linuxcnc.org/hardy/ubuntu-8.04-desktop-emc2-aj07-i386.iso
my guess is if you can load the newer version of ubuntu on your machine then when emc comes out on 8... you will be ok
so test it out and report back :)
I'm using the java client to connect to irc and the url you posted isn't fully shown
it should be clickable, but here's the directory: http://www.linuxcnc.org/hardy/
[13:47:22] <SWPLinux> http://www.linuxcnc.org/hardy/
[13:47:30] <SWPLinux> http://www.linuxcnc.org/hardy/ubuntu-8.04-desktop-emc2-aj07-i386.iso
ok, now it's really time for breakfast
got it will give it a try
can I unhook the probe input with g code?
or do I need to use M66 for touch off and punching...
what do you mean unhook?
digital output (m62-m65) with an and gate in hal?
oh I should have read back
which error are you getting BigJohnT?
I loaded 8.04 on a Dell 566 cell. triple booting W2K & 6.06 320mb ram intel 810 e no hitchs exept I deleted a partition and needed to renumber my boot.ini partition thanks jepler and all
I don't see any problem with moving down after the probe trips.
cradek sorry stepped away
when I try to move down after touch off I get and error and can not move down
what error? move down using jog? mdi?
using a g1 move
<BigJohnT>I don't recall the exact verbiage but something like this probe all ready tripped
if the probe trips during a non-probing mdi move, the move will abort
but it sounds like it should have already been tripped in your case.
yes it is tripped when I try to move
should I try and move up then back down after the probe?
I'm not at the machine now so I will have to test this evening
no, that will trigger the error for sure
if it stays in contact after the probe move, I think you should be ok
maybe you have a bit of noise on the switch. halscope would show for sure.
I can check this evening...
Morning all. I'm tryin to get my head around helical motion in 3-axes. if I'm at x1 y0 z0, and I want to make a one turn spiral ending at x1 y0 z1 with a radius of 2 units, the code would be "g2 x1 y0 z1 i-1 j0 k.5"? err... umm... right?
a helical motion is just like a regular circle
only that you add a Z-word
you don't need the K in the code you wrote
G2 x1 y0 z1 i-1 j0 <- should be enough
ok. what is the "k" used for if not that?
Jessica579 take a look on the emc wiki site for the socket head cap screw g code generator. It outputs helical motion
Jessica579: the K is used when you have an circle in the XZ or YZ plane
usually circles are in XY (so you only use I & J)
alex.... I think I get it. In my example, my z is a linear progression from z0 to z1. so no need for k. Now, if i wanted to cut a curved dome shape, I'd use "K". right?
you'd use a lot of circles
yes for a helix, two axes move in a circle, the other moves straight. the two that move in circles can be any two; you use the appropriate I,J,K letters for those two
also you have to select the right plane (g17,18,19)
Ok. Thanks guys!

Guest156 is now known as skunkworks_
this is really cool: http://openfarmtech.org/weblog/?cat=13
they make it sound so simple...
BigJohnT: at least they use emc ;)
yes i saw that
where did you see that?
in the section where they have a cnc torch
boundry layer turbine looks interesting
fenn_ is now known as fenn
hello is this where i can ask questions about setting up an emc system?
sendo: yes, just ask away ( but most people here at USA night-time ) if anyone can help you, they will
I resolved the G38 problem by just moving up and off the probe switch to finish the G38 move then I could Z down as far as I liked! SWEET!
for whoever is interested in solar-powered boundry layer turbines: http://dspace.mit.edu/bitstream/1721.1/37400/1/122931954.pdf
(and lots of 3d printer fun)
ok i´m converting an old LPKF mill (PCB mill) X and Y axis were no problem but Z axis is actually a solenoid and i´m kind off stuck on how to resolve that
i´m going to use PWM to achieve that
but how do i tell emc the axis is PWM driven?
it's just up/down?
you can use the 'comp' window comparator to turn a solenoid on if Z is within a certain range
i´m not sure i will have to experiment with that to get proper trackwidth and the LPKF info i have is inadequate
i´m guessing that to drill a hole in a pcb it will use 100% duty cycle but for making the tracks i´m not sure
sendo: does the Z axis have any provision for "feedback", so that the position the solenoid has been driven to can be measured in the PC?
does it have damping for feed
in emc, the way an axis moves is a black box -- emc produces a commanded axis value on the pin called axis.#.motor-pos-cmd and monitors a feedback axis value on a pin called axis.#.motor-pos-fb.
sendo: i think the depth of a drill is set deeper with the little plastic ring/collar on the bit
because most pcb drills would shatter if slammed into the board, there has to be a feed mechanism
archivist: i was thinking some kind of spring linkage
with a damper
some people hook stepgen in there, some people hook PID in there to control servers, but you can do anything that you can express in hal or with a custom hal component.
fenn: i use a modell servo for drilling PCB
but its bad
I would change the feed from solenoid to something else
seems like pcb drilling would also need to take place at a controlled speed
fenn there is a ring to adjust depth but its at 2 micrometer per notch or something i think that is to finetune trackwidth nothing more
there is however something i have never seen before it looks like a adjustable button with no wires attached as i said i really have nearly no info on the machine
take some pics and maybe we can help
the button is probably a damper
the "button" pushes in the Z+ direction
and return spring
yes i think so there is indeed a return spring i´ll upload a picture
hmm lvdt/opto and pwm to the solenoid may produce a workable servo
archivist: but without feedback?
with lvtd or opto grating
oh I should read what you're saying :-P
but if the damper is unidirectional
can the software servo deal with different damping rates dependent on direction
yes of course, you just can't (yet) do FF in one direction
in this specific case, having the drill or router bit snap back up quickly doesn't seem like it would hurt anything
or am I not thinking things through again?
[18:06:41] <sendo> http://img519.imageshack.us/my.php?image=img0669pb9.jpg
dang internet is lumpy today
the solenoid is on the fixed part of the machine and puches the spindle down
the threaded thing is the damper i think
i think jepler is correct about snapping up there will be only 2 tools used a spiral drill and a universal pcb cutter (engraving needle)
[18:16:09] <sendo> http://img132.imageshack.us/my.php?image=img0675qe6.jpg
thats from another angle
[#emc] "This is the #emc channel - talk related to the Enhanced Machine Controller and general machining. Website: http://www.linuxcnc.org/,
wiki at http://wiki.linuxcnc.org/"
sendo: if the 'z axis' only has 2 positions ( up and down ),
then stop thinking of it as an 'axis',
begin thinking of your machine as XY with a special function ( plot on/ plot off ).
The members here might think of a real positionable axis when you say 'z axis'. ;)
To do this you need a special ( tho simple ) setup ( it has X Y but no Z ) and maybe an M function to do Plot on / Plot off
it's just a word, but may help you get a solution ;)
like pen down and pen up
right ( HPGL)
thanks thats an idea i got to look into
sendo look at M64/65
but i was thinking that i might have nothing to do with actual positioning but rather a difference in duty cycle press down soft for making tracks and press down hard for drilling
sendo: that won't work without feedback
oh, if you want to do a 'floating head' then BigJohnT and Dallur have done similar for torches
btw, nice dust collection collar on the unit
hehe its an old machine from the school i attend and i got to do an essay on PCB milling and when i asked to do some testing they said they didnt have a machine for it
sendo: you can send the y-coordinate using pwmgen
a few days ago they said we found something but you got to fix it first.....
gefink: sendo said "Z axis is actually a solenoid"
tomp2: yes he want pwm to move slow
yeah annyway i would like to thank you all for your input but i got to go now
like close a relay slow with pwm? ok, cool
tomp2: i think on a voicecoil or how this is named
yes voice coils use pwm, and are solenoids
i got the datasheet of the solenoid and it can take a dutycycle of 15%
still need feedback ( and coil quality like voice coil motor ) you might make it into an r/c airplane like servo where it seekssome value ( like a sewing machine foot with pot tell it where the surface is ) but this is pretty custom
if you can be sure where the surface is, then you can skip all this
well thanks everybody but really got to go now
tomp2: thats right. i think thats not worth
and mechaniclly set up & down
bye have fun
alex_joni: did you see that I solved the probe issue?
heh.. nice name for a package "gstreamer0.10-plugins-ugly-multiverse"
* alex_joni heads to bed
good night all
tomp2: i like the sewing machine foot idea, better than an IR noncontact probe (less noise and immunity to dirt/swarf)
there are those spring loaded engraving spindle-carriers but it seems like trouble to me
what kind of repeatability and precision can one expect from a linear pot?
i bet you need < 0.001"
over short distances
hi fenn, a linear pot should be reasonable but no where near what you would need for precision cnc
for a start they are usually fairly linear, but not 100% linear over their track
pjm: this is just for measuring the height of engraving surface
in that case it could give you an idea certainly
what sort of accuracy u looking for ?
so as long as it's locally continuous (no backlash or switch bounce)
lewin1 is now known as lewing_
pjm: not entirely sure.. sixty degree cone, 0.005" features, somewhere around .001" i guess
plus of course the res would be limited to the resolution of the ADC measuring the output of the pot
can one use the term backlash in describing a sensor? or is that called hysteresis?
it might be easier to find one of the cheap ebay digital vernier based scales that has a serial output and modify that
for one thing, it's discrete steps of 0.0005", which will cause hell
and they're too slow
tooooo effin slow
how is the height of the table set? anything u could bolt an encoder on to?
anyone know exactly how slow they are?
i'd guess something like 1Hz
fenn i stuffed one on a lathe
too slow to work with
never used th serial connection, maybe the display is just slow
I think the electronics is slow to save battery power
pjm: this is a hypothetical machine, discussing sendo's options
i have one on the Z of my milling machine and it must update at around 10Hz at a guess, its quite responsive
he's retrofitting a plotter-thingy
i did find in my 'crap' an old Z axis off a multicam CNC plotter, only problem is the travel is only about 150mm or so
btw i think your mill's column is too skinny
my project mill?
with 100mm box?
yeah i cant decide about that, still umm'ing and ahh'ing about what to do re the Z
eh, i guess either it's satisfactory or it isnt
the only concern i have at the moment is high frequency vibrations
caused by the lack of mass supporting the Z
basic spring of the col will be a pain
a big cast iron lump would be better but this is what I have to hand
yeah try sand, or sand mixed with gravel and oil
yeah that is a good idea
(toxic waste disaster when you want to move though)
i'm gonna use one of the 'little machine shop' mini-mill heads
ah i guess one could mix soap with the oil before mixing it into the sand
which isnt massive in terms of motor HP
so i'm not sure that would bend the actual box section
the ones with plastic gears?
i have the belt drive mod kit..
i read all that stuff about the gears ;-)
pjm: HF uMill?
same thing pretty much
its the same as http://www.mini-lathe.com/Mini_mill/Reviews/Homier/Homier_mill_p3.htm
your choice of mt3 or r8
Yeah, that plastic gear crap went away REAL quick here to a belt drive.
only because its the same as my manual mill
but that particular mini-mill head looks quite interesting in terms of the motor controller
i think i'll go with mt3 also
since its PWM apparnently
or maybe mt2
well i'm collecting this mini-mill head on thursday so hopefully i'll have it running pretty soon
for the PWM I'm gonna try and get EMC to control it
K`zan, so u have one of the same type of mini-mill head as that one in the above link?
pjm: Nope that is mines big brother, I have the micro-mill, that is the mini-mill.
ahh ok got ya
and what u think of the micromill head in general?
i've only be able to go on the reviews i've read of the mini-mill
Original SUCKED, much better with the belt drive kit.
Between the variable speed and the pulley system it works out pretty good now.
ah yes i read a lot of people got tired of replacing the plastic gears
also the noise of them was commented about quite a lot
Plastic gears, what in hell where they thinking? I would have suspected they would have been offering a belt drive kit to make up for it, err, grub a few exta $$$.
well yeah exactly
Noise wasn't horrid, but it did NOT sound well at all.
the annoying thing is that i looked in the UK for one of those mini-mill heads
and the cost was just a joke
Overall the uMill sucks, but it is a hell of a lot better than no mill at all :).
less than 1/2 the price in the USA even taking the $/£ into account
Interesting, guess it is set up for what they market will bear rather than cost+profit.
it was cheaper to buy in the US and buy a plane ticket to go and get it
so i'm going tommorow to atlanta to pick it up and coming back monday
My new wireless antenna (bi-quad) gets me about 2x the number of sites I get with the stock antenna, but all weak and none open :-/.
Ahh good old ATL :).
Great place to be away from.
hehh i'm only going there as a stop gap to visit a ham radio fest in dayton
Good, been a LONG time since I went to Dayton. Miss the flea market to be sure.
ah cool, m0eyt here ;-)
amazing how many hams are into machine tools too
Live in an apartment with high voltage power lines and an industrial park across the street, so I am not real active as you might guess :).
near where i live the local hams have either a lathe or mill in their garages
Ah, thought that was G, guess enough folks coming aboard they had to expand.
ew /me was licensed
yeah it used to be G but apparently it ran out...
Here I know no hams at all. NEver get out and FM I just have a real hard time with.
but anyway one of the drivers behind making a CNC is to make parts for microwave receivers
that need a fair amount of precision, things like scalar feeds and conical feeds etc
Tried to get active on 6m, 2m and 70cm ssb/cw but antennas are a problem :-(.
The higher in frequency the better :-).
pjm: wtf you are flying to the US to get a chinese mini mill part??
pjm I used to do 10g tv
yeah exactly.. my lowest freq band is 2.3GHz and higest 20.2GHz
HF holds almost no interest for me, I can do that on my cordless or cell phone :).
fenn, cos the cost in the UK is about 4X that of the USA
.me envies pjm
so its cheaper to combine it with a trip ;-)
* K`zan envies pjm
that's just so wrong
well that is rip off britain for you
I stuck on the DC bands, highest is 70cm...
it was cheaper to buy a plane ticket and physically go and get it, than buy it from a UK outlet
can't you just have it shipped?
Well out of date, but: http://wrlabs.shacknet.nu/~vw/hamradio/
fenn, yeah i could have it shipped, but 40.5lbs to the UK aint cheap
it was about 2/3 the price of the plane ticket...
plus i have friends in atlanta so its an excuse to go and visit them for a catchup and some beers
I should get off my arse and go screw with the pipedream...
* archivist waits for the duty and vat charges on pjm's return
hmm but it was 2nd hand and i have the receipt to prove it!
or be screwed by the pipedream, as the case may be :).
K`zan: have you cut anything with it yet?
LOL, give the gov what it gives you so well.
K`zan, my radio pages are at www.uhf-satcom.com
pjm I imported my 100meg to 26gig sig gen from the states
fenn: Ran the EMC program it defaults to with a pen in the chuck, I got a LOT of work to do as far as alignment and strengthening goes.
pjm: I'm afraid to look :)
archivist, handy item...
yup sure is
and some network analyser bits
i only have a few bits of test gear here, mostly old stuff
well 1990's vintage
1990's thats new
but yes hopefully when i get back with this mill head in one piece
it should only be a matter of weeks before the machine is in a state to start cutting metal
wxtrack only wincrap :-(.
Too many nice pix there :).
ah yes that is a problem, it does run under wine..
Cool, will give it a go, have my ancient xp under vmware, but I do so loath to run anything wincrap.
ah btw i have a Q on the EMC live cd perhaps someone will know the answer too
its regarding services that run at boot time
Gotta go make a hole to get to work on the pipedream.
laters es 72/73 :-)
and i noticed from looking at the output of dmesg that stuff like bluetooth is started, so how can i stop all that stuff i dont need?
should i edit the /etc/rcx.d/whatever or is there a tool to do that?
I wish it would support my wireless card...
that damn SysV init crap is insane...
yeah i'm a slackware guy too
so these modern OS's are a pain ;-)
so ditch the %@##@%#$%$@#%$ distros
write your own rc scripts
It used to be better, but some damn geek had to wave his weenie to get it in, sigh.
use whatever init you want
ds2: In my copious free time, right? :-)
pjm did you ever go to the batc events about 10 years ago
it is quicker then dealing with that crap
<-- did it once for SLS
archivist, no not really been into the ATV stuff
ds2: I can't argue that....
archivist, mainly uWave etc
there is likely some silly gnome/gui tool to edit which services get started
pjm I was doing uWave testing at the annual rallies for a couple of years
archivist, this was a nice story on /. http://science.slashdot.org/article.pl?sid=05/12/19/041205
think on the F'ed stuff, sysconfig had something for it
archivist, ah that is interesting... perhaps I know you
fenn, yeah i looked at that 'boot up manager' but havnt installed it as yet, but it seemed to be a handy UI for editing boot time services
ok i need to go, gn all cul
6.06 silly gnome/gui tool 1 -> System ->Preferences->Sessions is where I put an emc --(ini) so my machine starts on boot up.
But then I also autologin
tool 2 -> System->Administration->Services also has a few we might not need.
I have emc2 installed (used live cd for install). I want to install vismach. Anyone here that can walk me through that real quick?
tool 3 System ->Administration->System Monitor. Then View All Processes.
But I still don't see bluetooth
what are these tool 1 / tool 2 / tool 3 things you're referring to?
6.06 silly gnome/gui tool
fenn, thought there might be such tools.
oh, the services manager also, but that's more for apache / sshd etc
that would be too l2 :)
Sure. I'm not seeing anything quite like the init.d manager from some other distributions.
hmmm. I saw one on some Ubuntu, but it might be a package I installed
had columns for the runlevels and services/daemons as rows
Seems like I had one of those a while back also.
Excuse me. Could someone answer a few quick questions?
you have two more questions. :)
lol... First, I want to install vismach. How do I go about that. I mean... where does vismach.py belong, etc...
I can't answer that one. next!
Where does emc keep all of its files (executables)?
(I think vismach can be more or less anywhere, but it may need to know the ini file or something)
installed or run-in-place?
I don't know what you mean, installed or run-in-place. I have installed emc2 on my hard drive (i installed from the livecd
ok, that's "installed"
you can find out where all the files are by running the command `dpkg -L emc2`
I believe configs are in /etc/emc2/
binaries are in /usr/bin
manuals in the correct man dirs ...
gotta run for a bit. see you later
HighOctane: if you use the sample configuration "scara" you will get a configuration which uses vismach to display a representation of a machine
HighOctane: in the file /usr/bin/scaragui (it's a text file; a program written in the python language that uses the vismach module) you can read the description of the machine. In the file scara_sim_4.hal you can see how the "joint-pos-fb" values are connected to pins of the "scaragui"; this is how the visualization knows what position to display
HighOctane: if you want to write your own machine description, you can use scaragui, hexagui, and pumagui as examples, and see a list of available primitives by executing 'pydoc vismach' at the commandline.
O.K. - Trying it now.
HighOctane: outside of what you see in pydoc there's essentially no other documentation.
Will the scara config run on a virtual machine?
yes, it should run OK (though you'll get the "unexpected realtime delay" messages)
It runs really slowly. Like 2-3 frames per second.
it uses opengl; if you are in a setup without hardware-accelerated opengl it is likely to not be fast
I bet glxgears runs really choppy also
all those sentences would have made great your mom jokes
"i gave your mother an unexpected realtime delay last night"
you're weird :)
looks like simple matrix math is patentable. well, who here is surprised at that. http://www.google.com/patents?id=k1eAAAAAEBAJ
(or if it's not the matrixes that are patented, it's "a method of putting multiple pieces of electronics in a single plastic shell"
USA patent system needs a kick in the bits
put the patent lawyers in front, ( come de revolution)
VAPT is all matrix math
Jepler: That's pretty cool, vismach is. I gotta get that on a real machine, with a good graphics card. What do you recommed. 512 VRAM and 2 gigs ram, or what?
well ATI have done it with the all-in wonder series..
^ have had good luck with the ati rage and 128 for opengl
i live on the old ATI cards...
always say unsupported but sometimes shit just works
the remote works on the linux box... but we lots it ....
i never did get the tv-in working... but who cares
HighOctane: well, for running emc and controlling real hardware, you want a simple graphics card and you don't want to install the proprietary opengl libraries (e.g., nvidia)
HighOctane: for visualization but not running real hardware, any of the chipsets with accelerated opengl support will work nicely (intel, ati, and nvidia being the majors there)
almost all users report that installing the nvidia closed-source drivers mean they get constant "unexpected realtime delay" messages, and often they find that after uninstalling nvidia they can't get any opengl programs to work anymore without major surgery
Even the open source NV driver has been known to cause problems. Might need to use the generic vesa driver
hey guys quick question, gecko's want an active low signal right? can this be done by just inverting the parport step pin?
