does anyone know how to use s32out in classicladder?
I figure I should use the ASSIGNMENT output thingy
I've tried various things for the Expression but I get errors saying I should use format @xxx/yyy@ and something with := in it "to make operate"
so I have no idea what it's supposed to do
BigJohnT: do we have much for classicladder docs other than the wiki page?
yes I have a few examples in addition to the regular stuff on classicladder
look, ladder docs
which thing is the OPERATE button?

looking here ^
is it the = ?
* BigJohnT looking
what I'm trying to figure out is how do I get values on S32outs?
yes it is the =, not sure why they called it that
hm, I tried %OW1=10 but got those two erorsr
when I add a "=" I get ASSIGNMENT, not OPERATE
are you putting an operate on the right most colum?
I'm on the wifes windows laptop so I can't look at classicladder at the moment
seems like the operate is just an assignment ...
it should be a %Wnn=10
%W are now internal, the s32in are %IW0, I think s32out are %OW0
but I'll try %W for fun
aha %W does work
my cat is keeping me from leaving my chair for the moment
cradek: just noticed this in a comment: /* verify if there is the '=' or ':=' */
but I guess the :, if present, is just eaten
hm %W2 doesn't end up as any classicladder.0.s32out-*
oh maybe it's QW not OW
dumb question did you configure any s32's for your classicladder
I have the hal pins
got it, duhhh
ok, I'll update the manual
%IW is s32in, %QW is s32out
(this is a new change he made)
so trunk only
sounds like a typo
yes I think so
how new is the change?
JymmmEMC: no, %Q are bit outputs, so %QW are word outputs
cradek: what is 'O' then?
JymmmEMC: I don't think it's anything
ok, that has been since he sent me the info for trunk
cradek: That's where I think it might be a typo... Input, Output - like you said
I timed a truck today - took me a long time to figure out that A=Before and R=After
Oh, these work nice, even under nix... http://www.dealextreme.com/details.dx/sku.474
Hey, anyone live outside US, but has fair trade agreement with US ?
I want a laser that can't be shipped to US =)

does anyone know the best way to put the board outline in an Eagle design?
I think you draw it with "wires"
eric_u, do you want to mill it out of the blank pcb? ie cut the board out? put a .1" wide wire trace around board outline on layer 46
(I use a surplus .1" rasp type pcb mill to cut out my boards
I want to send it to barebonespcb
hmmm... not sure what they want for production
they say "NOTE: Be sure to include board outline in your Gerber files"
the only board house I have used accepted eagle project files directly.... no gerbers needed
if you have any, you can use mechanical layers, you don't have to use copper
arg, curse fanuc, curse curse
aka 'wonder if I have any 6-40 screws'
cradek: what are you cursing about?
trying to wire up an old fanuc jog wheel but it wants (I think) 6-40 screws which I don't seem to have
6-32 would have been just fine
minor deal, sorry
jmkasunich: i am reading an email from japan panasonic about a motor they make for asian market.
under 'evaluation items' , item 'burnout test' ...
the result is ' no ignition, not more than the specified amount of smoke ' :)
whats the unit of measure :)
we screwed up a 5hp induction motor by doing something wrong with the field voltage
it filled the room up with smoke really nicely
actually, the motor still seems to run fine
careful, the smoke is from insulation ( dope or paper )
i call the laquer 'dope'
could be other, not up on new insulation materials
jst thought the 'specified amount ' of smoke was funny
eric_u: tomp is right - you may have damaged the winding insulation
could be, we aren't using that motor anyway
magnet wire varnish, or stuff that the winding was impregnated with after it was wound
it ran fine afterwards
might run fine for a while, but fail down the road, or fail hipot
motors are pretty darned rugged, but if significant amounts of smoke come out, they are NOT the same as they were before
advanced circuits has an explanation about how to zip up your design files, but not anything about the files themselves
they have a web DFM (design for manufacture check) that will tell you if there are any errors
I was going to use that
they do tell you about the formats they support: RS274D or RS274X
excellon drill files, blah blah drill master, etc
I saw that, but it needs to be a little simpler

ew eeeeevil mafffs
that maths is waaay over me
in that case you'd better stick to trivial kinematics machines
(me too, really)
has anyone rigged up a grinding setup to make round nosed lathe tools?
seems like it couldn't have any top rake, but that's probably ok, I'd just use it for finishing
archivist: that math is easy... the anwer is 42 no matter what the question is =)
oh wait, no RAID6
uh, here: http://www.newegg.com/Product/Product.aspx?Item=N82E16816116064&Tpk=16-116-064
SWPadnos: is that your christmas stocking stuffer pick of the year?
there were a few RAID cards in the "cyber monday" specials from NewEgg
and jymmmmmmm was looking for one
here's a better stocking stuffer: http://www.newegg.com/Product/Product.aspx?Item=N82E16822152102&Tpk=22-152-102
the newegg board photos look like a totally different layout from the board photo on the box (for the raid controller)
(you could at least fit it into reasonable-sized stockings)
yes, they do look a little different, don't they?
SWPadnos: All 4 port =( Only give about 3TB if you have a hot spare. I'd love 8 port then I can do 6TB+2 hot spare
wow, that's an awful lot of porn
hm, what's it cost to build a quad core / 4GB / 1TB these days. I need to, uh, test emc on one
yep, I was pre-coffee when I saw the first one - read "pci express x8" as "pci express, and 8 SATA connectors" :)
SWPadnos: I did too
jepler, $800 or less, probably
cradek: And you point is?
cradek: Not to worry, it's all QUALITY porn =)
but it depends on whether you use Intel or AMD
SWPadnos: I don't have a whole lot of brand loyalty for CPUs, I tend to go for lower price first, lower power dissipation second, and brand last.
that's a good order :)
personally, I'm not convinced there's 6TB of good porn on the whole planet
but maybe I'd stick performance in there somewhere
AMD has a couple of quad-cores that are 65W
SWPadnos: surely outside the "budget" lines there are no poor-performing CPUs anymore.
also relatively inexpensive at $170
poor perfromance is relative ;)
the quad-core Phenom compiles EMC2 (after a make clean) in about 20 seconds
though that's sim I think
here's an 8 SATA-II connector RAID card, dunno if it's not crap in some other way though. http://www.newegg.com/Product/Product.aspx?Item=N82E16816115026
but it does include depending everything
jepler, the computer I put together for ~$1300 a couple of months ago would now cost < $1000
oh, oops -- I wasn't paying attention to the raid features. it's worth doing raid in the card these days, not in the os?
and that's with 8G RAM, a WD Raptor 300G hard drive (3x the cost of 1TB today), and a Radeon HD4870, the fastest video card on the market (barring multi-GPU madness)
it is if you want to boot from a RAID-protected partition
so you can take your pick between being f**ked when your boot drive goes for being f**ked when the card goes
just boot from SSD :)
hey, I should patent that!
I think I'd pick door #1, steve
yes, if you've made proper backups and all, that would be the preferable door
which is darned hard to do with 6TB of data
but of a small boot partition it would be easy
well, it does require large numbers of tapes or a $manyK tape drive
in fact, as you suggest, you could just have a cupboard of SSDs all loaded with the kernel and initrd
you should keep your root filesystem to 1.44MB so you can back it up easily (minix advice)
the likelihood of an SSD failing is hopefully lower than that of a rotating media device failing
sorey, can't do that with bzImages :)
jepler: High Point raid anything == icky poo poo
I wish modern linux distribs would still use a small root partition with just the necessary things for booting. it would make disaster recovery much better.
yeah, the last disaster I had wasn't fun to recover from
Filesystem 1K-blocks Used Avail Capacity Mounted on
/dev/ad8s1a 507630 38842 428178 8% /
^ modern freebsd install
it mostly involved waiting for a tape restore of about 20k of files from /etc, but without that the system was useless
That was kinda the purpose of getting a REAL 8 port raid card... No backups, just swap out hdd offsite every so often. Especially now that 1TB drives are $100
8 port card will give me 6 drives (~5TB) + 2 hot spares
how can a 1TB offsite drive hold your 5TB of data?
cradek: The drives would be rotated off site
oh so you have several copies of at most 1TB of data?
or rdiff-backup to a secndary system offsite, but not too sure the expense (bandwidht) there
with 8 port card could do RAID 50, but no hot spares
mirrored Raid 5
"RAID 15" .. I think
0 strip, 1 mirror
I remember the 0 becasue that what you have left if a drive fails....zero
stop stripping the p from my striper
stripers are fish
(if you believe Billy Joel)
I dun know, cradek made a good point I didn't consider. Hmmm and all of of ports too - for hot spares
and way too long too long to rebuil the whole array
Hmmm, dual 4 port raid cards each running Raid5, then mirror em
at separate locations :)
SWPadnos: That's a LOT of bandwidth, even if just diff's
well, that's the idea behind "offsite backup" though ...
SWPadnos: any update would be a gig minimum
as they said in the 1970's: "never underestimate the bandwidth of a station wagon full of tapes"
crap load of drives, sure
today they'd say the same thing, but it would be an SUV full of hard disks
unless they have a1PT tapes now
unless they have 1PT uncompressed tapes now
500GB native is the largest I've noticed, but I was only looking at AIT/SAIT
I think there are higher capacity Ultrium tapes though
the tape industry REALLY needs to keep up with the hdd industry. they stopped doing that back in early 90's
well, there are 800/1600GB tapes
at $40 or so each
SWPadnos: did the vesa driver fix the odd video for you?
the drive is expensive as hell
skunkworks, haven't tried it yet
Hmmm, I think I can live with 3 TB +1 hot spare.... but it'll be kinda tight
bah! SWPadnos see what you started! LOL
* SWPadnos whistles innocently
SWPadnos: I do appreciate the lookout for RAID cards though =)
SWPadnos: I've been keeping my eye out for 1TB drives so as soon as I find/get a RAID card, will hit 3 or 4 frys
is fry's below $100 yet?
check out the WD Green drives by the way - several watts less power for each drive
SWPadnos: $98 I think - google 'mercury frys', first hit
SWPadnos: frus ads alternate content every two weeks
err evey other week
just run what I say thru typo translator
sounds like the grapevine in "Johnny Dangerously" :)
"Johnny and the mothers are playing stompin at the Savoy in Vermont tonight"
SWPadnos: on those green hdd's, what's the drawback on them?
"what, Vermin's going to kill my brother tonight?"
"that's not what I said"
"nah, but I know this grapevine"
they're not quite as fast as some others - not noticeably so, but it's inthe specs
RAID isn't what it used to be
used to be all about inexpensive drives....
it still is - there are hardly any expensive drives in the SATA space
go for high reliability drives, and the price goes up almost exponentially (if you can find them)
I just need mass storage, not speed
heh, I have Stompin at the Savoy by the Ink Spots :)
how come no realtime issues?
"don't buy these sysetms"
too late! :)
probably because the CPU has the memory controller in it, and the video subsystem has to wait
which is what causes the graphics problems - the video system doesn't get the data it needs for the display
selecting vesa probably does one of the other things he mentions -- changes color depth, resolution, or refresh rate
does VESA support 32-bit color?
it definitely looks better (but not great) in 1280x1024 mode, though I never tried 16-bit
I think the VESA standard does, who knows what vesa modes the device reports, though.
they work great for workstations.
the argument could be made that it's up to the driver to know these bandwidth limitations and refuse modes that exceed them
I loaned mine to a friend for a gaming con and the first thing he did was install video cards that weren't "dog slow"
could be - it's probably exacerbated by faster CPUs too
SWPadnos: at least 24bbp I believe
with the cost of reasonably high end video cards (some with 512M) under $50, it's a relative no-brainer to fix the problem :)
oh wait - 256M on board. still a no-brainer though
I've seen those cards that say something about "xxxMB memory, (xxx/2)MB on board" and wasn't sure if those are just as bad as shared-memory video solutions in terms of realtime performance
have you used them in machines with rt?
I've never used one
I think that just means that they use AGP/PCIe memory as video memory, like it was originally intended
err - main memory for textures ...
I don't know if they reserve that memory by default though, or just grab it when necessary (like when running a game)
[17:04:07] <SWPadnos> http://www.newegg.com/Product/Product.aspx?Item=N82E16814121235
not much point though
alex_joni: did you ever hear from that guy with the index patches for one of those cards hardly anybody has? ax1524 or whatever it is?
So - there was a reason why it got better at lower res's... If I would have lowered the color depth a bit I could have stayed with the detected driver.
it's mostly OK at 1024x768, 24bpp (=32 bits/pixel framebuffer)
I'll bet it's OK at 1280x1024@16bpp
(I'm just trying to figure out where to put the depth setting in the almost-nonexistent xorg.conf :) )
jepler: it was stg I think
jepler: stg, the guy was max something
and no, I didn't hear back
he said he was going to test the fix I commited on TRUNK
yeah, I wasn't sure if it had gone anywhere since then
didn't forget about it though..

[19:23:10] <skunkworks> http://www.electronicsam.com/images/KandT/servostart/amp.JPG
just haven't been motivated to work on it
actually finding the time is my issue
sould get a little better in the winter.. No outside work to do.
yep, the time issue is the same problem here...
I'm hoping there is some work to do at all this winter :/
well - there is work and work
jepler: what is your next project?
I have a chance to pick up a couple of servos from a mill, what do I look for on them to know if they are usable?
depends on a lot of things. How old? Brushed servos are the easier to find drives
brushless are a bit harder.
skunkworks: nothing really in mind at the moment
(my drive is for brushed)
not sure but not new for sure
will the brushes be easy to spot?
Just this once .. here's the log: http://www.linuxcnc.org/irc/irc.freenode.net:6667/emc/2008-12-01.txt
hey - tab complete works now on the pjirc java client.
if they are free - get them and sort it out later :)
that was my plan
you should see this mill it has a huge ring for a tool changer that circles the mill

* jymm buckles in for the ride...
this one is a 4' diameter ring or bigger
This is only 60 tools ;)
BigJohnT: Heh, the way you said it the first time, made it sound that the ring encircles the whole mill!
"for God's sake man strap yourselves in"
jymm yep looks like a halo
BigJohnT: the seatbelt was for the upcoming netsplit
jymm: they said it's back already
lol you lil devil... that's the ONLY way you'll see a halo for a while =)
alex_joni: Well, so did a 9yo girl sitting in front of a TV with static on the screen too!
BigJohnT: that is how we got these servos. http://www.electronicsam.com/images/KandT/DSC_0242.JPG
these are big like those
