Lerneaen_Hydra: beeing offline you probably missed this: http://freenode.net/news.shtml
alex_joni, okay. you go bbl.
That didn't work.
steves_logging is now known as steve_stallings
apparently it got steve's attention..
jepler: same here.. just got home :)
* alex_joni feels very sorry about lilo
jmkasunich: lets talk a bit in emc-devel
Thanks for the heads up re lilo. I just talked with him on the phone a couple weeks ago.
rayh: I know
Interesting how the web creates near personal relationships
near personal, but still disconnected
a regular on a mailing list or IRC channel sometimes just disappears
and you never know what happened
moved? change in interest? ill? dead?
got two more weeks of travel myself then home for a while.
Nice to have wiki working in predictable ways. Thanks guys.
somebody really should mention that installing emc on ubuntu and changinging the kernel to real time disables the printer
why does linux had to be such a godzilla about printers?
the problem is that many emc users use the parport for stepper signals
threeseas: you can still keep the printer and emc, but you'll end up with problems
problems which normal users can't solve
if the linux printer stuff is installed, then you wind up with your machine moving at 2am when the printer server resets itself
right, that's why I could safely assume. but all I wanted it for is simulation to test g-code
it _is_ possible to re-enable the printers
but we figured it was better to disable by default for the majority who are using steppers, and provide re-enabling instructions for the minority that aren't using the parport for their machine control
well this system will never be connected to a machine, only used to test code, so do I get a clue about printers?
I think the info needed in in our wiki
ok where are those instructions? :)
lemme see if I can find a URL for you
[17:34:43] <alex_joni> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?TroubleShooting
that covers the opposite problem
threeseas: you need to read #2
linux printer interfering with emc
and get the idea to edit /etc/modprobe.d/emc2 and comment the line inside
I think he wants emc to stop interfering with linux printing
networking printing would be an alternative.
jmkasunich: I know
alex_joni: I saw that about lilo earlier... :(
does the printer stuff even apply to nfs/samba/other or usb printers?
emc and non-parport printers should get along just fine
hmm, unless maybe cups is completely disabled to keep it from messing with the parport?
even usb printers should be ok
I dunno, I use a network printer
what jmkasunich said.
jmkasunich: cups is not disabled afaik
lpr shoudl still work though, even without CUPS, right?
Lerneaen_Hydra is it setup to network print?
Lerneaen_Hydra LPR can network print to an ip address
oh, ok. I was thinking lpr to <insert interface other than parport>
Lerneaen_Hydra Right, like NETWROK INTERFACE =)
less the typos =)
Lerneaen_Hydra are you 100% nix or do you have 2k/xp too ?
alex_joni: so that's the only line in that file? comment character is ?? # ??
my CAD/CAM only runs under 2k/xp, and I'
m too lazy to set up a VM
* Lerneaen_Hydra mumbles about the distance between ' and <enter>
Lerneaen_Hydra: Ok, there ARE nix services under XP you can install, That'll turn a printer on XP into a nox print server.
yes... answering my own question
If I set up a network printer it'l probably be on my linux box
which I'll also set up to be server for various other things too
Lerneaen_Hydra: I'd do it the ither way around personally, but whatever is best for your situation.
I'm not planning to set anything like that up anyway
Jymmm: a decent printer has LAN on board anyways
and I don't really need a print-server
Lerneaen_Hydra M$ has better driver support for advanced printer features than nix does.
Jymmm: right, but I think nix would make a better print server than windows
IIRC doesn't HP have first party drivers for most of their printers?
alex_joni Not all of us have 150 lb LJ 6 with JetDirect cards =)
* Lerneaen_Hydra seconds alex_joni
Jymmm: if only for the fact that you can easily archive the prints
Jymmm: and with CUPS you still use the M$ driver on the clients anyways
alex_joni you can do that with M$ too.
Jymmm: a decent colour laser printer with LAN is 6-700 $
I think that's affordable
what's a decent B&W laser cost?
speed wouldn't really matter
Isuppose I need to re-boot
alex_joni If you do that much color printing and can afford the $120 per color toner carteidges.
mainly cheap prints/page
Lerneaen_Hydra: it can go very low if you take ebay into account
I got a B&W laser with LAN for $149 new
alex_joni: oh, that's a good idea
Jymmm: even if you don't do that much printing, and change the 120$ only once in a while
The cost of the printer is nothing compared to the cost of the consumables.
Brother 1170N or something like that
jmkasunich: samba, nfs?
hey, it works
you can probably get some old L4 or something like that for 30-40$
I have no idea what the protocol is, I googled for instructions to make it work with linux, and it does
jmkasunich: Well, I know where you got yours from, so that doesn't count (as it was free)
I'll have to check out the gold mine at school this week
linux printing does suck, and I spend as little time as possible dealing with it
hmm.. the Google Site Search on linuxcnc.org works quite well
and finds stuff in the wiki too
they have this trash room where they thow away nice working stuff
jmkasunich WHAT?! You actually BOUGHT it?!
I bought it brand spanking new from Office Max
* Jymmm hides his head in the shame of it all! =)
Jymmm: Brother _used_ to be very bad
nowadays they _all_ are equally bad
which are worse
lol, not all surprisingly but most
Jymmm: the usual consumer crap
if you can afford a nice one (1k+) then it's probably good
I've had my LJ4p for over 10 years and it's still goin.
Jymmm: right, that's a very good one
I had some LJ1100 now a LJ1200
the LJ1100 had problems with feeding, so I brought it to a HP certified repair shop
I just sold a LJ4L for $25, worked perfect, just needed another toner cart.
and they didn't notice it's an US model, so they plugged it in 220V mains, and fscked all the components
alex_joni so what did they give you for a replacement?
did they say they were sorry?
jepler: not even
Jymmm: don't get me started..
it's a rotten society ;)
I'd call HP Corp and tell them their CERTIFIED repair are dumbasses
but then I ran out of people to call..
did you call the presidents office?
I would have needed to call HP US and tell them HP Romania are dumbasses
didn't bother for a 300$ printer
ick.. the 'new' yahoo mail doesn't work with Opera :-/
alex_joni: you got a replacement, right?
Lerneaen_Hydra: they said it wasn't covered by warranty
when they broke it?
and they won't cover any costs outside the initial work extent
didn't they break it?
Lerneaen_Hydra: they said I didn't tell them it's not an EU model :)
steve_stallings is now known as steves_logging
oh, random noticing, pressing up/down in MDI doesn't have similar behavior as a bash console would
IMO that would be rather practical
Lerneaen_Hydra: no sh*t ;)
Lerneaen_Hydra: actually it's a very nice feature.. but not really easy to implement
so why isn't that implemented?
jepler did it for halcmd
if you run halcmd -kf
then you have tab completion for names, and up/down history, etc
yeah, that's really nice
though IMO in MDI only up/down is of real use
as g-codes are so short
and have different parameters each time
history would be really good (r) though
Lerneaen_Hydra: patches happily accepted :D
I can't code. yet.
so wait a couple years ;)
I can wait.. no issues
so you can get wonderful undergrad-esque code
better than none
do I need to change anything in "make menuconfig" before building RTAI 3.4test2? or defaults are all OK?
acemi: never tried 3.4test2
but usually are defaults ok
İ tried it but I have some problem
isn't the real 3.4 released?
acemi: what kind?
for example EMC cannot remove module when shutting
cradek, no, the last stable is 3.3
Lerneaen_Hydra_ is now known as Lerneaen_Hydra

Guest402: is that Bas ?
Hi Alex, yes this is Bas experimenting with IRC
Guest402: any luck so far?
as you see we're not quite always responding imediately
oh, I see that you have an EMC & Ubuntu live CD
* robin_sz returns from taking his kids climbing
its amazing how cooperative they are when you have them dangling 20m above the ground on the end of a rope
darn Bas left
cradek: yup :(
might be getting late there
LiveCD with emc2
Hey skunkworks. How's it going?
Good. Been busy this summer. Nothing exciting done.
skunkworks: there's always next summer
Hopefully this winter I will be playing with emc some more.
alex_joni: what is the live cd based on?
rayh: how is the embedded emc2 controller coming?
just fiddling for now.
the halui stuff makes it a lot easier to hard wire a control panel.
more "stuff" to play with :)
It gets better all the time.
rayh: cool, let me know how it goes :)
I've got to get back to Roland's and update the Mazak.
* alex_joni dreams of large panels stuffed with knobs and switches
I made one of the servo drives - but have not had a chance to play with it much other than sending it a pwm signal and running a motor.
That sounds like progress.
rayh: btw, I never showed you pics of my 'new' machine ;)
No you didn't, alex
alex_joni is waiting for me to come back and say I burned up the ir2111 ;)
[22:05:47] <alex_joni> http://dsplabs.utt.ro/~juve/blog/index.cgi/projects/01157974398
skunkworks: I'm not waiting
I _KNOW_ it will happen
:) SO far so good.
skunkworks: actually I hope you'll never have any problems with it..
nice. I like the way you built the base to stabilize the xy table.
alex_joni: that should be fun to play with
I hope so
it is nice having 3+ axis's
skunkworks: but what do I know.. it's your mother tongue
I blame it on my schooling
There is some possible argument about proper word construction with plural axis.
You do nice welding, alex.
it was probably done with a robot :)
rayh: I should :)
skunkworks: nah, manual
and that is a pretty crappy weld..
only the thick powdercoat over it makes it look nice :D
I'll have to photo a good weld next time we fabricate somehting .. one of our guys is an artist with a MIG torch
ah. The wide gap welding stick, eh.
I say it's spelled axisses
cradek: 2A @ 45V from a L297/298 is not too much.. is it?
not a lot.
no but you want a nice heat sink
45 might be near the limit, better check
I use 42 I think
(with very good snubber diodes)
the diodes are the key really
it bothers me that axes can be "more than one axis" and "more than one axe"
yeah ... thats english for you
alex_joni: is it moving yet?
cradek: it was moving at one point :D
you can smelt copper
and he smelt a rat
nah, the PWM was audible
about 14-15kHz I'd say, really annoying
so I asked my coworker to do something about it :)
you can't hear it over the sound of the spindle can you?
I think he has it at 40kHz now, and it's not moving at all
cradek: who said I'll have a spindle?
* alex_joni still ain't sure what to do with it
maybe a probe..
a felt-tip pen
even that ;)
how about invisible ink?
to make invisible paintings... :)
looks like you already have that
do you have 3 drivers already?
I have 2 G201's
and this homebrewed
alex_joni: your going with servos?
wish I had bought more geckos
skunkworks: stepper geckos
aww - thats cheating
skunkworks: I have plenty of G340
but I have no idea how to mount encoders to this small mill :)
I'm used to big iron ..
and the motors I have around, can probably tear it to pieces
I bet :)
although I have some _really_ nice ones on the new robots
about 20x10x10 cm
that must be a tight little package
(sorry - sounded almost sexual.)
lol.. the main idea is : high voltage, low current for the same power
which means smaller wires, smaller package
and usually lower inertia too
only advantages ;)
makes you wonder wth the chip manufacturers didn't make high voltage power mosfets sooner
cause its hard to make a good high voltage mosfet
actually, its not always better ...
by the time you add a gearbox,, the effective inertia of the motor goes up square law
robin_sz: these are usually with 1 level reductions only
so a fast spinnng low inertia motor with a 20:1 gearbox can end up higher effective inertia than a slow, heavy motor with a 5:1 box ...
well I have been running emc2 all weekend on the computer that was reverting back to the login screen - it has been running. Odd
it is a 400mhz pentium II compaq that seems to like the 600mhz pentium III I stuck into it. Nice speed for me.
It took me a bit to get the case open - it has a security solenoid that was tripped. The bios didn't have a password in it and I was able to get in and deactivate the solinoid.
yay about the live cd
I thought there was a live cd a while ago - was that the breezy live cd?
skunkworks: yes, I think it was breezy
no install option
this is live + install if I understand correctly
and latest updates
I was in the middle of installing dapper, then emc2 from cvs when I heard of new cd, will I miss anything?
live CDs are just a convenience thing
dapper + cvs is as up-to-date as you can get
tomp: can I ask why you didn't use the install script?
did use it
1st I install dapper, then run the emc2-install.sh
then what did you mean by "dapper, then emc2 from cvs" ?
i download dapper iso, and install it, then run the shell script
then get release version
what, should shell script be the end of the line?
the shell script _does_ get you the released version (I think)
users of the released version don't have anything to do with cvs
emc-wiki instructions are to use cbs to get released version, I cant argue with the instructions
can you point me at that wiki page?
because that is wrong, and needs fixed
cvs != released
thats the whole point of cvs, it is the bleeding edge development version
it could be that you, tomp, need the cvs because you want to experiment with some bleeding edge features that aren't in the released version
but that should be a concious decision made by you, not something you are lead into by a bad wiki page
john, i know you know better, but the instructions are ther for getting 'release' and i followed the instructions, conciously yes, but ver batim
so what instructions did you follow? if you give me the url, I will fix them
[23:47:36] <tomp> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl/emcinfo.pl?Installing_EMC2#Getting_the_source_with_CVS
those are two separate methods of getting EMC2
1 is for precompiled packages
section 1 is the section you wanted
2 is for CVS
section 1 sends you here http://www.linuxcnc.org/index.php?option=com_content&task=view&id=21&Itemid=4
short and sweet.
I think you get more with cvs, but that you can run with method 1
cvs gives you the source code
which you only need if you are going to be editing the code
I dont know enuf to argue it, i just wondered if the live cd offered more or newer, thanks
cvs can also get you the latest development version, instead of the released version
the LiveCD probably has some updates that the stock Ubuntu 6.06 doesn't (around 300M, last time I checked)
unless you're installing from a very recent 6.06 (6.06.1)
updates entirely unrelated to EMC tho
yes, but updates that you'll be asked about until you install them ;)
some of which are important, such as X updates
ok, i did use 6.06.1 and thanks again
which you can do with a click once the install is done
sure. it's just the 300M of download (though a 600M ISO is more, so it's not really a savings to get it)
its a savings if you haven't already downloaded the original dapper CD
yes, just finished the updates, phew! after over an hour i was afraid of a hangup, and was looking at the live cd and a wipe of the partition
heh - yep
emc2 runs, thank you all.
if you went to ubuntu.org today and downloaded an iso, you'd get the latest, right? or would you still need 300M of updates?
tomp: thats good
they did an interim release - 6.06.1
otherwise, you'd need all the updates
I think their policy is to change the ISOs as infrequently as possible
well, I can agree with that
install, then use the update manager to stay up to date
when there are so many updates that the manager needs to dl 300M, then its time for new isos
right. I'm not sure why they did an interim release, but it could be due to X or installer issues
I'm guessing to save people bandwidth
that too ;)
especially if you have dialup and mailed away for the CD, you don't want to do the install and then find out that half the damned cd is out of date and needs downloaded anyeay
at the rate they ship, it's faster to download on dialup ;)
