yeah - I was all "mindset' to spent hours hoisting that beast into position, and now I find it isn't here...
hi, is it possible to run scripts/emc when not loged in as root. I did the make setuid setp but cannot run as normal user
rtai fails to allocate shared mem
works fine as root
error is RTAPI: ERROR: failed to map shmem
I can run "realtime start" with no errors
take up manual machining?
David36_LA: most of the developers are pre-occupied at the moment.

David36_LA: how did you install?
David36_LA: that works fine with a live cd or an install done with a live cd. also, i think its make ; sudo make install when i build a run-in-place system from cvs
[02:54:46] <Jymmm> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?RtaiSteps
another bug.. it seems udev deletes the shared memory device files <Not a bug - udev maintains a dynamic /dev, creating and deleting devices on demand.> ... this is confirmed by rebooting, and /dev/rtai_shm and /dev/rtf[0-9] disappear. a temporary fix to this problem is to re-make the device files, then tell udev not to delete them. sudo (cd /usr/local/src/rtai-3.2/ ; make dev ) sudo cp -a /dev/rtai_shm /etc/udev/devices/ sudo cp -a /dev/rtf[0-9] /etc/udev/d
but that was last updated 2005
wtf are they doing
did they just ship machines in
they've been there for years
i am half excited, my place of business might use emc for a diamond turning machine
which would be a cool project to get paid to do
toastydeath: for turning lenses?
they used to be manual machines
and the controls they stuck on them suck really bad
so if it works one one, it might make sense to put it on the other three
because it doesn't use g-code
and doesn't have any real control mechanism other than basic feedrates/repetition
which is a problem, because while it has "roughing" cycles, EMC does not
and that's a major part of the operation
if i had any sort of legitimate programming ability i would try to code type I roughing
You just gotta love it when you're uploading at 1M BYTE /s
you're talking about lathe roughing cycle?
type II would be difficult to code
but type I doesn't allow a decrease in X
where can I find a good description of how type I is programmed and what it does?
or the Haas manual i believe has a pretty good description
[03:12:50] <cradek> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?HaasRoughingFinishing
someone (maybe you?) made this page
i've never been to the wiki
that's quite the
long example for something that's a bit simpler than that
unfortunately the page is not descriptive enough to implement
anyway type I roughing is usually g71
maybe it needs an example or something
the important parts are the P and Q words
it reads the block that starts with P
and ends at the one with Q
it looks for the profile
whatever toolpath is defined
then turns down to it, in steps
cradek: 2 words.. rigid tapping. Your getting sidetracked ;)
could you draw a picture with the dimensions and toolpath shown?
i think i can just find one
give me a minute or ten
that would be helpful
skunkworks: I've written some lathe programs here for demos, and the roughing is tedious
here's a fanuc example
[03:17:19] <toastydeath> http://toolingandproduction.com/archives/1098/1098sptk.asp
please note after a g71/g72 roughing cycle, after the Q block
calling g70 after it (no words necessary) will cause the lathe to follow the toolpath exactly
that the last g71/72 cycle turned to
the example i found didn't mention that
I'm puzzled by the M.08 (doesn't help that it's floating between two lines)
oh I see, it's on N6
too bad I can't see those dimensions :-/
the haas cnc lathe programmer's guide
like, has twelve pages on the subject or something
but i can't find it, sorry
anonimasu: check your email now or when you wake up
hmm, this is a lot more complicated than I expected
are you looking at type I or type II
in type I, you may only increase X as you get closer to the spindle
so there's no clearance issues
type II is the one with clearance issues
it is aggrivating that the most important lathe canned cycle is the hardest to write
poor old jmkasunich... gets to ditch work for a week and STILL stuck behind the computer coding.

* archivist is waiting for some shiny new object to appear in front of the webcam "look what we made!"
me mostly make a mess
<-- some stuff done on the lathe
archivist: we haven't made chips on mazak yet
nice cnc threading here would be very nice
scroll down for the "evil bullets" also made on lathe: http://axis.unpy.net/01181527543
emc2.1 does threading .. emc2.2 will add some more lathe features as detailed in that second URL
Im just quoting for some parts where I need to "borrow" a local cnc
www.archivist.info/p6130001.jpg for example shapes
doesn't look like anything too tricky, but you need the right equipment (I don't have it either)
yes a local machine shop has a new hass tl2 and no operator, so if the price is right I can go and play with it
in some respects it looks slower than using the capstan here
does emc do tapered threads
jepler: here: http://axis.unpy.net/01181319466
I cannot download the file go-rtai-smp.sh
is that file available?
in axis, trigger a limit switch in auto mode. then, do the following sequence: trigger estop (f1), trigger estop reset (f1 again), and click "Override limits." the resulting EMC_AXIS_OVERRIDE_LIMITS would not work (but it should), and emc drops the message packet without any sort of response message (at least not in DEBUG = 0X 7FFF...). yet another bug...
for the lazy folk who ask for repeatability procedures but are unwilling to try them out: "would not work" in this case means that clicking on the "override limits" would mark its check box momentarily, after which the check mark would disappear again.

hai ricevuto la mia mail?
stamattina ho preparato la macchina con ubutu 6.06 amd64
ho chiesto sopra per il file...ma jepler ancora non ha risposto
ah, io l'ho mandato a Radek
no è jepler
ho spedito i CD all'AITEm
domani vengo in dipartimento
ma è rimasta una copia per me?
ancora devo vedere quello con il filmato
il filmato va bene, la voce è quella di Roberto....
si fa quello che si può...
l'hai visto quel box linux?
hai capito che fa?
è più o meno quello che ho io
una scatola tutto compreso
c'è dentro un embedded, una scheda per la gestione dei motori, e l'alimentatore
e quanto ne vogliono?
non c'èil prezzo
se non ricordo male
e quale linux li pilota?
non c'è scritto...ma non c'è scritto neanche che software usa
mi pare strano che abbiano fatto un software loro...
ma la macchina 64 bit funziona?
ha solo il sistema operativo installato e funziona
ho dovuto solo sistemare la scheda video
in modalità vesa
quindi ora si dovrebbe cambiare il kernel
ma il file che non si riesce a scaricare cosa dovrebbe fare? Cosa è SMP?
appunto, ma la procedura descritta fa riferimento ad un file che non c'e'
no, a quanto ho caipto è una procedura che crea dei file .deb per aggiornare la macchina
senza stare li a copiare comandi astrusi
quindi crea tutto quello che serve? Oppure serve solo ad attivare l'SMP...non ho capito bene perchè il nome del file è go-rtai-smp
SMP = Symmetrical multi processing...ma non so bene cos'è, posso intuirlo dal nome
I can't read most of that, but there is a file missing from my website. I can't put it online until next week when I am home
after monday, remind me if I have still not put it online
what exactly do that file?
jepler, thank you
Vado a cenare, a domani

ds2: Hey Fry's has a 8 port 10/100 switch for $5 today is the last day of the sale on it.
ds2: what, you dont' do networking?
he only uses 2 port switches
ds2: you carry around a floppy between your computers?
alex_joni: LOL xover huh?
JymmmmEMC: I have a pile of about knee high of switches
ds2: switches or hubs?
also got hubs
get rid of the hubs QUICK! just toss em in the trash
the hubs are integrated part of the router
what this "router" from 1942 or what?!
hm, I thought `s/hubs/switches/` was true, not the other way.
nothing that nice
maddash: you mena performance wise? Hun's are layer 1, switches are layer 2/3 you want a switch, not a hub.
maddash: or broadcast traffic will suck the life out on your lan.
stop broadcasting then!
chuck samba and windows
ds2: disable arp, yeah... riiiiiiiiiiiiiiiiiight
you do NOT need ARP to work
why don't I just disable anything above layer 1 while I'm at it.
only if they broadcast
disabling arp enhances security of your network
if it isn't doable, why do you think the option is offered by ifconfig?
why not just use string and tin cans instead!
wiretap issues with strings ;)
because it's nix, and you can do anything!
there are places who have for practical purposes did away with ARP
and most wireless routers offer that option
ARP is about as required as DHCP is required
* robin_sz got his new toy today
got the nitrogen generator today
the final stage compressor is "interesting"
20HP motor, 3 stages
dunno what it acheives in practice, but the guage on the third stage goes to 10,000 psi
nice bit of kit though, decent PLC and HMI on it
Is it possible to add a REVERSE switch to most common household box fans somehow?
robin_sz: You got a hooker as a toy? Nice!
robin_sz: You adding that to the "company perks" so your employee doens't have to go Thailand now?

maddash_ is now known as sudo_maddash
robin_sz: how much did your laser cost?
sudo_maddash, which one?
grep -ri debounce *
my trumpf YAG laser cutter?
robin_sz: the cheaper one. i'm thinking of getting one myself, because my bits are getting chewed up.
the price for a new one, or second hand?
mmm ... about 200K dollars should find a good used one, maybe 8 to ten years old
* sudo_maddash goes back to breaking bits
mine was about 500K USD new
how many watts are those YAG laser cutters?
ds2, they vary ... mine is 800w, but there is a 1200W version too
equivalent to about 1500 and 2500w of CO2 laser
robin_sz: is that enough to cut copper sheets?
hint: the mirrors in CO2 lasers are made from what metal?
aren't they gold sputtered? (guessing)
psht. what can an laser do that a wire edm can't?
sudo_maddash, and cut at 20m/minute
robin_sz: my cnc bits cut plastics fine
sudo_maddash, you asked: what can an laser do that a wire edm can't?
er, did you haphazardly tack on a zero?
robin_sz: lasers do 20 meters/minute?
what kind of power does one need to do SLOW engravings on balsa wood?
robin_sz: at what thickness?
sudo_maddash, yes lasers do 20m a minute in thin stuff, like 1mm
10W?! sigh so much for solidstate lasers
the biggest solid state lasers I see around are about 1W
you are kidding arent you?
no; just basing on what I actually found (not what I read about and no one seems to sell)
robin_sz: what about 50 mm?
<-- laser newbie
sudo_maddash, 50mm is generally too thick for laser ... plasma or waterjet
ds2, most industrial pump diodes are 25 to 100w
robin_sz: in actually use outside of a lab?
ds2, yes, in common useage
obviously, you dont use them on their own
i should see where I can find one of those cheap/surplus
you arrange a few kw of them in a bank to be useful
ds2, try ebay
robin_sz: sorry, but I am morally oppose to doing business on ebay.
(which might be why I don't see the higher power lasers as being 'available')
for balsa Id use a 10W sealed CO 2 tube
expect to pay about $100 to $200

well, you can order them direct from Coherent if you prefer
a packaged 40w bar will set you back around 10K
thats why a 10w sealed co2 is a better plan then
isn't the power supply a hassle?
go to a medical eqpt auction
what about cooling? seems the commercial ones use liquids
by a complete co2 system for a few dollars
that would be ideal
$friend went to a medical eqpt auction this week
bought a hi tech YAG for 50
several smal co2 went for <20
sudo_maddash_ is now known as maddash
I'd offer to pay $40 for something like that =)
first find your local med eqpt auction
damn, how does this debounce gadget work?
donno how to do that around here
or, offer someone on here a say, 25% comission to buy you one on ebay
robin_sz: I just offered 100%+ commision!
see if anyone takes it up
* robin_sz is in the uk
my other lasers are argon and co2
wow, apple macs .. moronic or what
$mate just maile dme .. he has a mac, and a file in ".hqx" format, ie compressed. obviously, it doesnt handle this natively, you need some sort of add on decomressor

each one is supplied in a compressed format
