[00:04:22] <pfred1> it looks CGI but i guess it is for real?
[00:04:30] <toastydeath> it's for real
[00:05:02] <toastydeath> he's got a good photographer
[00:05:08] <toastydeath> or is a good photographer
[00:05:29] <toastydeath> it's just crosslit and that gives things a very surreal quality to them
[00:09:48] <pfred1> this is fake http://www.hec.nasa.gov/news/gallery_images/hubble_rns_compare_lg.jpg
[00:10:22] <pfred1> well one of them is
[00:12:27] <toastydeath> i'm going to guess it's the one that isn't slightly out of focus and has a crumpled, metallized cloth finish
[00:14:05] <pfred1> they made it with this: http://www.hec.nasa.gov/news/gallery_images/discover_ibm_0309.jpg which I don't think would fit very well onto my desktop
[00:14:50] <pfred1> I wonder if it runs Linux?
[00:15:01] <pfred1> good chance it does
[00:16:10] <pfred1> hmmm they're not saying but I can't imagine it is running anything else
[00:16:49] <toastydeath> there's no reason to have an ssi machine for raytracing
[00:17:01] <toastydeath> so chances are >95% it's linux
[00:17:22] <pfred1> http://www.hec.nasa.gov/news/features/2009/hubble_rns.072809.html
[00:19:04] <toastydeath> runs suse linux, apparently
[00:19:09] <toastydeath> http://www.nccs.nasa.gov/cluster_main.html
[00:19:15] <pfred1> oh it says?
[00:19:34] <pfred1> that looks like a different machine
[00:19:41] <toastydeath> same one
[00:19:59] <Jymmm> Valen: A universal charger perhapse? http://www.mini-box.com/OpenUPS
[00:20:59] <pfred1> yeah you almost have to be retarded today to run a cluster on anything but Linux
[00:23:21] <toastydeath> linux still doesn't do ssi very well
[00:23:33] <toastydeath> so there are some very large clusters out there that run other unix variants
[00:23:41] <pfred1> pretty soon we won't need telescopes we'll just be able to make everything up with CGI
[00:26:20] <Jymmm> http://en.wikipedia.org/wiki/Tandem_Computers
[00:26:37] <Jymmm> (Guardian OS)
[00:27:18] <Jymmm> I will say the Himalaya's were very nice.
[00:28:41] <Jymmm> alex4nder: You ALMOST had me sold on that mobo. I still might, but doubtful.
[00:29:03] <alex4nder> Jymmm: what?
[00:29:07] <pfred1> Jymmm what do you need a mobo for?
[00:29:27] <alex4nder> buy whatever you want
[00:29:36] <Jymmm> alex4nder: It has a realtek nic chipset instead of an intel
[00:29:42] <alex4nder> no it doesn't
[00:29:52] <Jymmm> Yes, it does. Read the specs
[00:29:53] <pfred1> realtek nics are fine
[00:29:59] <alex4nder> Jymmm: dude, I have the board in front of me
[00:30:11] <alex4nder> I pased the PCIe info the channel earlier.
[00:30:21] <alex4nder> +to
[00:31:09] * pfred1 Linux and realtek got back a loooong time ....
[00:31:43] <pfred1> ne2k baby yeah!
[00:32:03] <alex4nder> Jymmm: http://downloadmirror.intel.com/20714/eng/DN2800MT_TechProdSpec02.pdf <- or you could read the specs
[00:32:16] <alex4nder> and see the Intel *257$L gigabit ethernet controller reference in 1.11.1
[00:32:25] <alex4nder> er 82574L
[00:32:43] <pfred1> is intel gigabit better than realtek gigabit somehow?
[00:32:51] <alex4nder> in theory yes
[00:33:46] <pfred1> expound on the theory I'm fascinated
[00:34:06] <Jymmm> alex4nder: ok, they fscked up http://www.mini-box.com/Intel-DN2800MT-Mini-ITX-Motherboard
[00:34:35] <alex4nder> yup
[00:34:38] <Jymmm> alex4nder: But some intel mobo's DO come with realtek
[00:34:43] <Jymmm> nics
[00:34:47] <alex4nder> of course, but not this one.
[00:34:51] <pfred1> yeah because intel knows it don't matter
[00:35:13] <Jymmm> pfred1: There are KNOWN issues under linux for relatek nics
[00:35:20] <Jymmm> and have been a for a coupel fo years
[00:35:44] <pfred1> Jymmm nothing I've ever known about
[00:36:05] <Jymmm> pfred1: ok, so you dont know anything, that doens't change the fact.
[00:36:19] <pfred1> Jymmm got a link?
[00:36:32] <Jymmm> nope
[00:38:42] <alex4nder> well whatever
[00:38:45] <Jymmm> alex4nder: Ok, I may try it. But I'm kinda looking at the Jet with 6 sata ports
[00:39:00] <alex4nder> haha I don't care man, get whatever board floats your boat.
[00:39:10] <Jymmm> O_o
[00:39:16] <pfred1> I think it all boils down to feathres
[00:39:24] <pfred1> features not feathers
[00:39:27] <alex4nder> haha
[00:39:42] <pfred1> hey if you're that way maybe it does all boil down to feathers
[00:40:19] <alex4nder> yah
[00:40:26] <alex4nder> you look at your requirements, and you make a choice.
[00:40:36] <Jymmm> Hmm, I wonder if that OpenUPS + that intel board would be a good match
[00:40:41] <pfred1> or look at what is on sale
[00:40:47] <Jymmm> literally same price
[00:41:10] <pfred1> because in 2 years it is going to be so much junk anyways
[00:41:15] <Jymmm> alex4nder: What cables does it come with?
[00:41:40] <alex4nder> sata, and power for a sata drive from the motherboard
[00:42:01] <pfred1> Jymmm right now you want pcie3 and usb3
[00:42:42] <Jymmm> alex4nder: 1 or 2 pair of cables?
[00:43:12] <alex4nder> 2?
[00:43:24] <Jymmm> k
[00:43:28] <pfred1> why does sata power come off the mobo?
[00:43:41] <alex4nder> because the motherboard has an integrated power supply
[00:43:46] <Jymmm> alex4nder: do they give any specs for the power connectors?
[00:43:54] <Jymmm> alex4nder: internal
[00:43:56] <alex4nder> yah, they're in intel's tech document
[00:44:06] <pfred1> alex4nder is this an atom board?
[00:44:11] <alex4nder> yup
[00:44:13] <Jymmm> ok, only on pg18
[00:45:03] <alex4nder> you need to read the product tech specs
[00:45:14] <alex4nder> section 2.6.1 has a full breakdown on component power consumption
[00:45:27] <pfred1> what is it like 16 watts?
[00:46:02] <alex4nder> the CPU isn't the huge sucker of juice
[00:46:07] <alex4nder> it's all the little bits you can hook to it
[00:46:23] <alex4nder> I'll do a write-up on it once I actually test it on the mill
[00:46:26] <pfred1> forget about that what is it bare?
[00:46:37] <alex4nder> read the specs
[00:46:48] <alex4nder> there are all sorts of different conditions
[00:46:59] <alex4nder> idle is like sub 10 watts or something
[00:47:15] <pfred1> sounds typical for an atom
[00:47:46] <pfred1> dual or quad?
[00:47:53] <alex4nder> dual
[00:50:14] <pfred1> ah ha they haven't even released the quads yet
[00:53:22] <Jymmm> alex4nder: 30¢ for a powee connector?! that's outragous!!!! lol
[00:54:26] <alex4nder> I picked up a DB25 to IDC26 adapter, and a case
[00:54:29] <pfred1> woah the newest atoms aren't very cheap
[00:54:44] <alex4nder> the case has got room for a mesa pcie card
[00:54:50] <pfred1> you could buy a real PC for what they cost!
[00:54:58] <Jymmm> alex4nder: Heh, I got a bag of those =)
[00:55:53] <Jymmm> alex4nder: it sas 8-19VDC, you shoudl try a 9V battery for the hell of it
[00:56:08] <pfred1> it'd work
[00:57:10] <alex4nder> yah
[00:57:13] <alex4nder> until it doesn't. ;)
[00:57:30] <pfred1> take a bit before it fell below 8V
[00:57:41] <alex4nder> I'm using two supplies on my mill right now.. 13.8v and 48v
[00:57:43] <alex4nder> so it works out
[00:58:14] <pfred1> it seems there are no Linux drivers for the latest atom GPU
[00:58:30] <alex4nder> there are
[00:58:36] <alex4nder> they're just binary only, and old.
[00:58:38] <alex4nder> which blows.
[00:59:44] <pfred1> then wikipedia is out of date
[00:59:52] <Jymmm> Cool, they still have BIOS recovery mode. I hope they NEVER get rid of that feature.
[01:00:26] <alex4nder> pfred1: I tried getting them working today.. Meego is shipping with them
[01:00:38] <alex4nder> but they're an older ABI, and I don't want to downgrade X
[01:00:45] <pfred1> alex4nder you have an D2500?
[01:01:14] <alex4nder> dn2800mt
[01:01:17] <Jymmm> pfred1: are you having a bad hair day today by chance?
[01:01:26] <pfred1> Jymmm why?
[01:01:30] <Jymmm> pfred1: are you having a bad hair day today by chance?
[01:01:35] <pfred1> Jymmm why?
[01:01:42] <Jymmm> answer first
[01:01:51] <pfred1> no my hair rox
[01:02:07] <Jymmm> well, other things dont and why I asked
[01:06:42] <alex_joni> what's a 'custom solutions header'?
[01:07:02] <Jymmm> alex4nder: I only see the one sata power connector (I) near edge of heatsink on section 1.1.2, is it a dual cable?
[01:07:27] <Jymmm> alex_joni: This mobo doesn't use ATX 24 connector, it runs from 8-19VDC directly, any source
[01:07:45] <Jymmm> alex_joni: rear panel coax, or on board molex
[01:08:00] <alex4nder> Jymmm: the power cable is multiple connectors.
[01:08:10] <Jymmm> alex_joni: ah, thanks.
[01:08:27] <alex_joni> Jymmm: that doesn't answer my question
[01:08:47] <Jymmm> alex_joni: then rephrase the question
[01:09:18] <alex_joni> http://www.intel.com/support/motherboards/desktop/dn2800mt/sb/CS-032652.htm
[01:09:26] <alex_joni> what is 'X'?
[01:09:57] <alex4nder> alex_joni: it's in the tech specs
[01:10:00] <alex4nder> http://downloadmirror.intel.com/20714/eng/DN2800MT_TechProdSpec02.pdf
[01:10:16] <alex4nder> they should have just called it 'misc. signal connector'
[01:10:23] <pfred1> I can't figure out what CPU alex4nder's board has on it
[01:11:06] <alex4nder> N2800
[01:11:26] <alex_joni> alex4nder: so it's some bits you can access?
[01:11:56] <alex4nder> alex_joni: yes and no, it's more of a grabbag
[01:12:18] <alex4nder> SMB_{CLK,DATA}_RESUME, 3.3v standby. PWRBT#, HDMI CEC, Watch Dog Timer, Ground
[01:13:11] <alex_joni> ah, so not really usefull ;)
[01:13:31] <alex4nder> I guess that depends on what you're doing. ;)
[01:13:36] <alex4nder> someone cares about it
[01:14:30] <Jymmm> alex_joni: Here you go... http://www.pcworld.com/article/143777/the_secret_feature_on_your_hdtv_hdmi_cec.html
[01:14:56] <Jymmm> alex_joni: You can now control your pc via tv remote
[01:15:57] <alex4nder> I think it's more like, now your custom digital signage control boards can now receive that signal and do something with it.
[01:16:06] <alex4nder> like turn your machine on and off.
[01:16:09] <alex_joni> Jymmm: when it works :)
[01:16:10] <Jymmm> alex_joni: Err, I meant to say your CNC fro your TV Remote =)
[01:16:31] <Jymmm> alex_joni: Hit the REWIND button and see what happens =)
[01:17:03] <alex_joni> they don't mention linux support for it :D
[01:17:08] <alex_joni> http://www.intel.com/support/motherboards/desktop/sb/cs-008326.htm
[01:18:10] <pfred1> alex4nder so this is what you have? http://www.amazon.com/Intel-BOXDN2800MT-Desktop-Board-DN2800MT/dp/B006XFIK08
[01:18:26] <Jymmm> alex_joni: That's only becasue those lazy ass romaian developers haven't written one yet!
[01:19:05] <pfred1> freaking romaians we should throw them back to the Klingon empire!
[01:19:21] <Jymmm> I say the wolves
[01:19:24] <Jymmm> alex_joni: http://en.wikipedia.org/wiki/HDMI#CEC
[01:20:47] <Jymmm> alex_joni: Glorified Karioki machine maybe?
[01:22:01] <Jymmm> Hmmm, now to find a LCD panel that fits
[01:23:32] <Jymmm> alex4nder: the ONLY thing they missed was making the coax connector switch out the internal/external power.
[01:24:14] <alex4nder> pfred1: yup
[01:24:28] <pfred1> alex4nder Intel says it could be cheaper
[01:24:41] <alex4nder> Jymmm: I don't really understand the importance of something like that
[01:24:43] <pfred1> Recommended Customer Price $96 - $101
[01:24:57] <alex_joni> pfred1: was that meant for me?
[01:25:10] <alex_joni> Jymmm: but this way you can power something else from it
[01:25:22] <pfred1> alex_joni I don't think so
[01:25:47] <pfred1> /msg alex4nder Intel says it could be cheaper
[01:26:21] <alex_joni> pfred1: no, I meant the comment about romanians and klingons
[01:26:45] <pfred1> alex_joni do you have pointy ears?
[01:27:37] <alex_joni> pfred1: I might develop them later
[01:27:45] <pfred1> alex_joni green blood?
[01:28:33] <alex_joni> in appropriate lighting
[01:28:52] <pfred1> then you should go back to the Klingons
[01:29:21] * alex4nder sets up a Debian repository
[01:58:45] <DJ9DJ> moin
[02:17:27] * Valen looks at installing a terminal server farm :-<
[02:27:06] <Jymmm> alex4nder: If it had a switched coax connector on the rear, you could (potentially) make the internal connector a battery
[02:28:11] <Jymmm> a standby battery
[02:28:53] <Jymmm> I guess you could do it anyway, but would need to add some intelligence to it
[05:16:23] <r00t4rd3d> e-ndy, you are not important enough to have an away nick.
[05:16:29] <r00t4rd3d> no one cares
[05:39:23] <e-ndy> a still tongue makes a wise head
[05:54:16] <r00t4rd3d> my tongue didnt move during the typing of that sentence.
[06:04:04] <e-ndy> but that doesn't imply, that you are wise :)
[06:07:12] <jthornton> e-ndy, please turn off your status reporting it seems to toggle back and forth constanly and floods with messages about your being away from your keyboard
[06:14:01] <Loetmichel> mornin'
[06:40:52] <jthornton> morning
[06:55:35] <Tom_itx> hey
[07:45:43] <jthornton> logger[mah], log
[07:45:44] <logger[mah]> jthornton: Log stored at http://linuxcnc.mah.priv.at/irc/%23linuxcnc/2012-04-30.html
[10:20:28] <jdhNC> pcw?
[10:23:04] <pcw_home> ?
[10:25:12] <jdhNC> is there a way to keep my pwmgen from floating high when linuxcnc is not running?
[10:25:30] <jdhNC> 7i43/7i47
[10:28:17] <pcw_home> One of the 7I47outputs will be low before Linux CNC starts. chose this output
[10:29:15] <jdhNC> one of the pair?
[10:29:44] <pcw_home> (this is the inverting output = +)
[10:29:55] <jdhNC> when I use the other half of TX0, the pwm is reversed
[10:30:22] <pcw_home> Then invert the PWM output (is_invert)
[10:30:51] <jdhNC> nice. i'll try that tonight. Thanks.
[10:31:28] <pcw_home> sorry tag is "invert_output"
[10:32:18] <Gromits> Anyone familiar with Gladevcp reload object?
[10:35:50] <pcw_home> so its something like
[10:35:53] <pcw_home> setp blah.blah.blah.gpioN.invert_output true
[10:37:05] <jdhNC> I found an example where you answered a similar question a few months ago.
[10:47:12] <JT-Shop> pcw_home: we had a power failure yesterday and trying to restart the BP with the 5i25/7i77 only the analog pins show up on the 7i77 when I view them in show hal config. Any suggestions?
[11:00:57] <pcw_home> Check field power
[11:02:08] <pcw_home> 7I77 is like the 7I76, all bit I/O is powered by the 12/24V field power
[11:03:45] <JT-Shop> field power 24v CR3 is on
[11:07:26] <pcw_home> so you restart EMC and only the encoders/analog show up?
[11:10:04] <JT-Shop> yes, I powered down everything then powered back up a couple of times
[11:10:12] <JT-Shop> let me look to see the encoders show up
[11:10:57] <JT-Shop> yes encoders show up under 5i25
[11:13:08] <pcw_home> Well I guess the next thing is to check the 24V and then the 3.3V on the field I/O isolated side
[11:13:46] <pcw_home> also (5I25 part of) dmesg may help
[11:20:25] <JT-Shop> where do I check the 24v and 3.3v?
[11:23:15] <pcw_home> 24V is on the input (VIN = TB2 pin 5) relative to TB2 pin 8 (field power gnd)
[11:25:25] <pcw_home> 3.3V is on the bottom side of L1 (little ferrite inductor on center left of TB2) above lower electrolytic (C33)
[11:27:12] <JT-Shop> ok, I checked 24v on TB2 and that is ok
[11:30:27] <JT-Shop> what is the gnd for L1?
[11:34:45] <pcw_home> tb2 pin 8 (field power gnd)
[11:37:52] <JT-Shop> ok
[11:40:59] <JT-Shop> 3.28v on L1
[11:42:01] <JT-Shop> I'll clear dmesg and reload the config with an input
[11:42:11] <pcw_home> OK so maybe its a I/O fault of some kind. can you pastebin the dmesg
[11:48:45] <JT-Shop> hmmm, for some strange reason I had to reboot and now it works
[11:55:16] <pcw_home> power cycle or just reboot?
[11:59:09] <JT-Shop> reboot
[12:06:53] <pcw_home> Well thats mysterious then...
[12:38:26] <Tom_itx> logger[mah]
[12:38:26] <logger[mah]> Tom_itx: Log stored at http://linuxcnc.mah.priv.at/irc/%23linuxcnc/2012-04-30.html
[12:44:16] <Tom_itx> ok, what do you use to bleed off the main caps on power off? i asked this yesterday and someone said the power led was sufficient. i considered a 500 ohm 10w r or so. will the led's bring it down in a timely manner or should i look for another bleed off source. ~20,000 uf caps ~50v
[12:44:37] <Tom_itx> and does it matter if the logic supply comes online before the main supply?
[12:45:01] <Tom_itx> steppers with a 7i43 7i47 board
[12:47:34] <pcw_home> well a fairly hefty LED current of 10 mA would be 5K Ohm = 100 seconds time constant
[12:48:00] <Tom_itx> my psu board will have a place for 3 leds
[12:48:45] <JT-Shop> Tom_itx: on my phase converter I put some panel indicator lights AB for each phase and they work good to drain the caps...
[12:48:48] <pcw_home> do you like bright LEDs (newer LED are so efficient that they are often blinding at 10 mA)
[12:49:05] <Tom_itx> also, i'm coming off the centertap of one transformer to get a lower voltage for my 5v smps for the logic
[12:49:18] <Tom_itx> i don't care about the leds. i can hide them if i don't like it :)
[12:49:41] <Tom_itx> i've got some old old leds that should work good for this
[12:50:29] <pcw_home> for servos I would have an active charge dump but at 50V and step motors thats too much trouble
[12:51:07] <Tom_itx> i considered a relay or a dpdt power switch and use one leg for a resistor drain
[12:51:31] <Tom_itx> simple but effective
[12:51:42] <pcw_home> Yeah that good for servos as it will do braking as well
[12:52:24] <Tom_itx> i hope to get some wiring done on the stepper drivers today
[12:53:36] <pcw_home> Shorting out step motors doesn't work the same way it does with servo motors unfortunately
[12:54:03] <Tom_itx> the short would be at the psu caps
[12:54:38] <pcw_home> yes this brakes servo motors
[12:54:53] <Tom_itx> oh really? even thru the driver?
[12:54:59] <pcw_home> yes
[12:55:05] <Tom_itx> good to know
[12:55:11] <Tom_itx> i guess that makes sense
[12:55:20] <Tom_itx> since they act as a generator
[12:55:44] <pcw_home> the driver is just a single or 3 phase bridge rectifier if theres no gate drive
[12:56:05] <pcw_home> (with the DC out on the capacitor terminals)
[12:58:31] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/cnc/psu/psu_index.php
[12:58:34] <Tom_itx> progress report
[12:59:06] <Tom_itx> i need to find / build a box for all the driver psu stuff
[12:59:37] <Tom_itx> i lucked out on that heatsink material. scrap yard bonus
[13:04:20] <Tom_itx> the sherline spindle motor was bitchin about taking a full cut off those fins for a mounting flange
[13:05:12] <Tom_itx> i miss the Okumas
[13:05:43] * Thetawaves nuked his power supply project yet again so just went and bought a danfoss s1000
[13:06:33] <Tom_itx> mine were surplus and so far are working out quite nicely
[13:06:51] <Thetawaves> the transformers?
[13:07:04] <Tom_itx> yeah
[13:07:17] <Thetawaves> it is nice to use transformers in home made psu, i can't find that kind of iron though
[13:07:20] <Tom_itx> 50v dc at about 18A
[13:08:03] <Tom_itx> i checked the output of each one before i combined them
[13:09:04] <Thetawaves> you know about hooking them up in the same direction and such
[13:09:13] <Thetawaves> yeah?
[13:09:14] <Tom_itx> yes
[13:09:17] <Thetawaves> k
[13:09:27] <Tom_itx> i joined them after the bridges though
[13:09:38] <Thetawaves> why?
[13:09:43] <Tom_itx> otherwise i would have checked the phases
[13:09:51] <pcw_home> Nice heatsink
[13:10:01] <Tom_itx> because i originally was gonna make 3 supplies but decided one was better
[13:10:04] <Tom_itx> so i had the parts
[13:10:13] <Tom_itx> pcw_home i got about 8' of it
[13:11:37] <Tom_itx> Thetawaves, i did join the primaries on the transformers though
[13:15:01] <Tom_itx> this is way overkill for the sherline but i'm building for future expansion
[13:15:49] <JT-Shop> Tom_itx: looking good
[13:24:30] * Jymmm lol @ Tom_itx
[13:26:50] <Jymmm> Tom_itx: nice find on the heatsink though
[13:27:22] <andypugh> A guy on the forum is using some useful looking servo amps, 220VA input, and they take step/dir or quadrature or analogue or serial input.
[13:27:33] <andypugh> (22VAC I mean)
[13:27:55] <andypugh> No, I don't mean that either. I mean 220V AC
[13:28:02] <Jymmm> =)
[13:28:24] <Jymmm> I liked the 22V AC better
[13:29:13] <Jymmm> 22V AC @ 220VA works for me =)
[13:30:52] <Tom_itx> Jymmm you don't like my wiring job? :)
[13:31:24] <Jymmm> Tom_itx: Your wiring is perfectly fine
[13:31:47] <Jymmm> I like the c channel for the xfmr mounts too, easy to carry without pinching fingers
[13:33:01] <Tom_itx> i'm just using stuff i have on hand
[13:33:27] <Tom_itx> i hope to find / make a box for it all
[13:33:46] <Jymmm> Tom_itx: I might have used grommets on the holes though, I can't count the times there has been a micro-slice in the insulation and cause intermittant shorts.
[13:34:00] <Jymmm> hard to locate too
[13:34:04] <Tom_itx> yeah i put thick heatshrink around them
[13:35:41] <Jymmm> those edges still look sharp, did you deburr them?
[13:35:46] <Tom_itx> yup
[13:35:51] <Tom_itx> both sides
[13:36:37] <Jymmm> still look sharp to me but *shrug*
[13:36:41] <Tom_itx> it's probably all gonna come apart again anyway once i get the boards for my caps
[13:37:14] <Jymmm> Tom_itx: I'd bevel the edges with a reamer or large drill bit
[13:37:26] <Jymmm> no 90deg edges
[13:37:27] <Tom_itx> i used a debur bit
[13:37:41] <Jymmm> ok, maybe it's just the photo then =)
[13:38:21] <Jymmm> Why did you mix/match solder/crimp-ons?
[13:38:57] <Tom_itx> did i?
[13:39:15] <Jymmm> Looks like it to me... http://tom-itx.dyndns.org:81/~webpage/cnc/psu/psu4.jpg
[13:40:04] <Thetawaves> servo motors seem expensive and weak compared to steppers, whats the deal?
[13:40:13] <Tom_itx> i cheated and took the sleeve off some of them so i could get both wires in then i soldered all the wires in place and put heatshrink over the bare ones
[13:40:36] <Tom_itx> Thetawaves they're not weaker, you use them differently
[13:40:48] <Jymmm> Tom_itx: you soldered the crimpons?
[13:40:56] <Tom_itx> sure did
[13:41:10] <Thetawaves> Tom_itx, how so?
[13:41:12] <Jymmm> Tom_itx: not a good thing to do just fyi
[13:41:12] <Tom_itx> i don't like stuff coming loose
[13:41:20] <Thetawaves> gear down because they run faster?
[13:41:23] <Tom_itx> and pray tell why not?
[13:41:50] <Thetawaves> soldered crimpons are bad for cables, things that move
[13:41:57] <djdelorie> Thetawaves: servos provide MUCH more torque at higher RPMs
[13:42:05] <Thetawaves> the copper will fatigue at the end of the solder
[13:42:08] <Tom_itx> i don't think those are gonna move
[13:42:17] <Jymmm> Tom_itx: the solder makes the wire strands a solid and brittle, more tendancy to break
[13:42:29] <Thetawaves> it's not an issue for case wiring
[13:42:34] <djdelorie> Tom_itx: I used to solder crimps too, but no longer.
[13:43:32] <Thetawaves> djdelorie, how comparable are servo motors for small movements?
[13:43:39] <Jymmm> I used crimpsons all the time, but I have a $100 pair of crimpers too. The wire will break before coming out of the crimp.
[13:43:44] <djdelorie> if tuned right, I can hold 0.09 degree
[13:43:44] <Jymmm> s/used/use/
[13:43:45] <Thetawaves> where the higher rpm isn't necessarily used
[13:43:49] <Tom_itx> it's funny how forums and opinions vary
[13:44:03] <djdelorie> and since they're encoder based, I *know* where they are when they're "microstepping"
[13:44:28] <jdhNC> I know where my steppers are too... somewhere between the real steps.
[13:44:31] <djdelorie> Mine can do 100 oz-in continuous, 350 oz-in intermittent, and that's from dead stop to 3000 RPM
[13:44:34] <syyl> mh a correct done crimp will never come loose
[13:44:40] <Tom_itx> Jymmm, i have a $10 pair and kept the $90
[13:44:43] <syyl> soldering makes it only bad :(
[13:44:54] <Jymmm> Tom_itx: you used a lighter to shrink the tubing?! *sigh* what am I going to do with you
[13:44:56] <Thetawaves> so the screw design for servo systems isn't usually direct drive?
[13:44:57] <djdelorie> jdhNC: the difference is "somewhere" vs "I know exactly where"
[13:45:19] <Jymmm> Tom_itx: and thuse why you dont trust it well enough that you think you need to solder it too.
[13:45:28] <Thetawaves> sort of djdelorie, your encoders aren't exact
[13:45:31] <djdelorie> Thetawaves: I geared mine up/down to match the screw rods, but I suspect direct drive is popular.
[13:45:31] <Tom_itx> i wouldn't anyway
[13:45:42] <djdelorie> Thetawaves: how do you know?
[13:45:57] <Thetawaves> i suppose it depends on the encoder technology
[13:46:10] <djdelorie> Another advantage of encoder-based systems: you can't possibly "miss" a step, you just lag behind until you catch up
[13:47:00] <djdelorie> so, for example, my controllers keep track of the motor position even when the motor power is removed, and can correct when power is restored
[13:47:10] <Thetawaves> so 350 oz-in from dead stop to going... that is pretty handy and also not mentioned anywhere in the specs about these motors
[13:47:30] <Thetawaves> i assume you have 100oz-in rated servos
[13:48:10] <Thetawaves> ac? brushless dc? brushed dc? what kind of servos
[13:48:58] <djdelorie> http://www.electrocraft.com/files/ead_bldc.pdf page 9, mine are the DA34GBB-13 graph
[13:49:24] <djdelorie> ok, 340 oz-in ;-)
[13:50:11] <Jymmm> JT-Shop: what was the name of the place you got your power supply from?
[13:50:46] <djdelorie> They're marked DA34FBB-3AA, brushless DC, 160v design voltage, 134 oz-in continuous stall, 335 oz-in peak, 5000 RPM max
[13:51:14] <Jymmm> what is "continuous stall" ?
[13:51:28] <djdelorie> continuous stall is the equivalent of a stepper's "holding torque"
[13:51:40] <Jymmm> ah
[13:51:50] <Jymmm> funny name
[13:52:09] <Jymmm> continous hold seems like a better name
[13:52:20] <djdelorie> the terms assume the motor is running at some RPM, so "stopped" means there's so much load on it that the motor stalled
[13:52:37] <JT-Shop> Jymmm: Antek not Antec which is the first to show up with a google search even if you type in antek
[13:53:01] <Jymmm> JT-Shop: ty
[13:53:09] <Thetawaves> why can't i find the column for the 34G in that table?
[13:53:09] <JT-Shop> http://antekinc.com/
[13:53:57] <JT-Shop> dang my 24v power supply is shorted in the CHNC...
[13:54:21] <Tom_itx> probably used heatshrink instead of grommets :)
[13:54:55] <Jymmm> JT-Shop: Does the CHNC has fuses internally on the 24V line?
[13:55:06] <Jymmm> s/has/have/
[13:56:24] <Jymmm> JT-Shop: If there are 24V relays, pull them till no more short. I bet one might have arc'ed closed or some such nonsense.
[13:56:53] <JT-Shop> circuit breaker and the power supply has a fuse but it is not blown
[13:57:18] <JT-Shop> Jymmm: been there done that, the only thing that trips the breaker is the power supply
[13:57:58] <Jymmm> JT-Shop: 24V breaker?
[13:58:09] <JT-Shop> 120vac breaker
[13:58:27] <djdelorie> those tend to be slow-trip
[13:58:28] <JT-Shop> Jymmm: it is the power supply for sure
[13:58:30] <Jymmm> JT-Shop: is the PS original to the chnc?
[13:58:37] <JT-Shop> yes
[13:59:14] <Jymmm> JT-Shop: Ah, well shit... that's an easy fix =) I thought you meant the OTHER side of the PS.
[13:59:29] <JT-Shop> what other side
[13:59:36] <Jymmm> The Dark side!
[13:59:41] <JT-Shop> I thought so
[13:59:56] <Jymmm> JT-Shop: the 24V side of the PS, not the AC side.
[14:00:26] <Jymmm> JT-Shop: Doesn't your new PS have 24V too?
[14:00:32] <JT-Shop> it's on the inside not the AC side or DC side
[14:00:59] <JT-Shop> the Antek is for the plasma and it has 5v and 12v
[14:01:06] <Jymmm> oh
[14:01:06] <Tom_itx> winding shorted?
[14:01:07] <JT-Shop> for/in
[14:01:37] <JT-Shop> dunnno Tom_itx
[14:01:55] <Jymmm> JT-Shop: Heh, contact antek and see if you get qty discount =) LOL
[14:02:45] <Jymmm> JT-Shop: Oh ghetto it together using wallworts temporarily =)
[14:03:04] <Jymmm> JT-Shop: Ghetto Swamp!
[14:03:09] <JT-Shop> nothing was cooperative enough to leave a smoke trail
[14:03:31] <JT-Shop> we should have some power supplies at the other shop on the shelf
[14:04:10] <JT-Shop> about 1/10 the size of this mod squad era power supply
[14:04:23] <Tom_itx> gotta lovem
[14:04:37] <Jymmm> mod who?
[14:04:58] <JT-Shop> Jymmm: I don't need an Ankek power supply for the CHCN
[14:05:12] <JT-Shop> just a little 24v one for some relays
[14:05:27] <Jymmm> Tom_itx: And your telling me this, why?
[14:06:36] <Tom_itx> telling you what?
[14:06:59] <Jymmm> Tom_itx: nm
[14:07:06] <Jymmm> JT-Shop: I was kidding.
[14:07:18] <Tom_itx> send me a torroid and i'll use it
[14:07:47] <Jymmm> Tom_itx: Fine, it's 1/2" across, now use it!
[14:08:32] <Jymmm> I've never understood why xfmr mfr's NEVER put specs on them.
[14:09:01] <Jymmm> I find zillions of torroids/xfmrs and it's a guess at what they are.
[14:09:48] <Thetawaves> only a few minutes left on the clock http://www.spacex.com/webcast.php
[14:10:50] <Jymmm> Tom_itx: how much of that heatsink you have left?
[14:10:56] <Thetawaves> T-0:47
[14:10:59] <Tom_itx> plenty
[14:11:07] <Jymmm> Tom_itx: width?
[14:11:10] <Tom_itx> 5"
[14:11:22] <Jymmm> Hmmm
[14:11:45] <andypugh> Hang on, I have watched James Bond films, it's impossible to stop a countdown!
[14:11:47] <JT-Shop> clock is stuck
[14:12:01] <Jymmm> andypugh: =)
[14:12:11] <Tom_itx> andypugh they are set to stop at .001 sec
[14:12:16] <Jymmm> andypugh: It's Bond, James Bond I thought.
[14:12:45] <andypugh> Evil Overlord rule 4. Have the bomb detonate at 7 on the timer.
[14:12:47] <JT-Shop> someone call Wernher he can count down in several languages
[14:13:13] <alex4nder> yoh
[14:13:40] <andypugh> If the rockets go up / who cares where they come down? / He's our kind of Nazi is Werner von Braun.
[14:14:26] <JT-Shop> yep
[14:18:36] <andypugh> Is there any update on what is going on? (other than the Twittter feed, as I am not a twit)
[14:23:17] <andypugh> T -13 mins
[14:24:43] <JT-Shop> what's a twit?
[14:26:08] * JT-Shop will let someone else answer how to make a CNC color by numbers kit...
[14:26:19] <andypugh> Someone who uses Twitter, I assume
[14:26:43] <JT-Shop> must be... wonder what a Twitter is?
[14:27:23] <Tom_itx> a twizzle of tweets
[14:27:58] <JT-Shop> do they taste like Quail?
[14:47:00] <Jymmm> JT-Shop: possum
[14:47:28] <Jymmm> JT-Shop: gritty and mean as hell!
[14:47:33] <Jymmm> at least momma is
[14:48:22] <Loetmichel> soo, a step further... 16V 20A Spindle power: done! 32V 3A Stepper power: done! now i have to make a 5V 0,5A supply for the Stepper driver and a 12V 0,5A suppy for the Limit switches. -> http://www.cyrom.org/palbum/main.php?g2_itemId=13155
[14:50:20] <tom3p> i cant take advantage of this deal, but its 4 axis cnc edm with 16posn atc, servos and linear scales, 64amp p/s, dead clean, free delivery http://tinyurl.com/d82vzxu
[14:50:32] <tom3p> hope someone gets it
[14:51:05] <FinboySlick> tom3p: It is indeed quite lovely.
[14:51:06] <Jymmm> Loetmichel: or jsut use a PC power supply
[14:51:10] <djdelorie> holy pricetags batman!
[14:51:48] <tom3p> dirt cheap look around
[14:51:50] <Loetmichel> Jymmm: the PC PSU is "downstairs"
[14:51:59] <Loetmichel> (in the other compartment)
[14:52:02] <tom3p> include erowa nose on the c axis
[14:52:17] <Loetmichel> i dont WANT to use the PC psu for the stepper power
[14:52:39] <FinboySlick> Loetmichel: Are you being picky again?
[14:53:20] <Jymmm> Loetmichel: I've harvested 12/5V PS from external hdd cases before, perfect size
[14:53:24] <Loetmichel> and the 5V and 12V are no problem, the left Toroid Transofter has fitting windings already, just some rectifiers, son caps and a 7805/7812
[14:54:11] <Jymmm> Loetmichel: Look for the old external scsi drive cases, they have an internal PS and a IEC connector on the back, usually fused and EMI/EFI filter built in.
[14:54:23] <Jymmm> EMI/RFI
[14:54:29] <Loetmichel> Jymmm / FinboySlick: no, not picky, but i dont want to use the PC PSU cause i can switch the PC on and off without activating the Stepper PSU
[14:54:54] <Jymmm> Loetmichel: I'm not saying use THE pc ps, I said use A pc ps
[14:55:02] <Loetmichel> Jymmm: the transformer is already there, why not use it?
[14:55:13] <FinboySlick> Loetmichel: I wasn't even following the discussion... It just seemed like a good opportunity to pick on you.
[14:55:16] <Loetmichel> you mean: another one?
[14:55:22] <Jymmm> Loetmichel: xfmr is AC, you still need the rest
[14:55:58] <Jymmm> Loetmichel: Look for the old external scsi drive cases, they have an internal PS and a IEC connector on the back, usually fused and EMI/RFI filter built in. Cheap too
[14:56:00] <Loetmichel> so what? like i said: some Capacitors, a 7805, a 7812, a little Heatsink, done ;-)
[14:56:11] <Loetmichel> all components i have here
[14:56:56] <Loetmichel> to be honest: i am no fan of SMPS, i avoid them where i can
[14:57:19] <Loetmichel> to bad overload capacity and to noisy dc ;-)
[14:57:25] <Jymmm> I undestand not liking sw ps,
[14:57:36] <Jymmm> Just a Q&D solution is all
[14:57:54] <Loetmichel> Jymmm: MORE dirty as the photo i just showed?
[14:58:17] <Loetmichel> that "§$"§&%( machine will bie CRAMMED with electronics down in the base ;-)
[14:58:21] <Loetmichel> be
[14:58:33] <FinboySlick> While on this topic though, how realistically small could one make a 20V DC 9Amp PSU?
[14:58:42] <FinboySlick> (from 120VAC.
[14:58:53] <Loetmichel> xformer or SMPS?
[14:58:54] <Jymmm> Loetmichel: NOTHIGN is that dirty, not even a $2 crack whore on 'get down and dirty for free day' =)
[14:59:12] <Loetmichel> hrhr
[14:59:51] <FinboySlick> Loetmichel: I assume that a transformer would make it bigger.
[15:01:06] <Loetmichel> you assume richt
[15:01:08] <Loetmichel> right
[15:01:27] <FinboySlick> the design priorities would be 1, no electrical (and preferably acoustic) noise. 2 compact.
[15:01:50] <Loetmichel> oh, no noise.
[15:01:54] <Loetmichel> -> no smps
[15:02:09] <Loetmichel> the filters will be bbigger than the xformer ;-)
[15:02:24] <FinboySlick> Basically, I want to replace this: http://shop.lenovo.com/SEUILibrary/controller/e/webca/LenovoPortal/en_CA/catalog.workflow:item.detail?GroupID=460&Code=0A36227&category-id=1BD1071447A5491FBFADF0D7ECCCFC10&hide_menu_area=yes
[15:02:30] <Loetmichel> do you have three phase?
[15:02:47] <Loetmichel> why?
[15:03:12] <FinboySlick> Because it wouldn't take much for it to be bigger and heavier than the laptop it powers.
[15:03:26] <FinboySlick> It's enormous.
[15:03:33] <Loetmichel> oh.
[15:04:01] <FinboySlick> I'm exagerating... But still, I'm having trouble finding laptop cases that can accomodate the PSU comfortably.
[15:04:09] <FinboySlick> And I figured it'd be an interesting electronics project.
[15:04:15] <Loetmichel> lets put it this way: i have to dismantle and modify Notebook PSUs in my daily job.
[15:04:16] <Jymmm> FinboySlick: There are MANY aftermarket PS like that. Do you really need 170W though?
[15:04:33] <FinboySlick> Yes, the laptop will get angry with 95W
[15:04:34] <Loetmichel> the PSUs are as cheap and compact as it gets
[15:05:19] <FinboySlick> Loetmichel: OK. I assumed putting more time/money on it might help me.
[15:05:28] <Loetmichel> there is NOTHING to omit to make it smaller
[15:05:54] <FinboySlick> It's also hissing so I figured I'll need a replacement at some point.
[15:06:09] <Jymmm> FinboySlick: It's an i7, not under warranty still?
[15:06:22] <Loetmichel> hissing mustn be a sign of an early death
[15:06:56] <FinboySlick> Jymmm: Yes. I'll have it replaced, but I would have enjoyed replacing it with something that doesn't weigh 2 pounds.
[15:07:16] <Loetmichel> most of the time the hissin is just a not perfect moulded HF transformer
[15:07:16] <Jymmm> FinboySlick: At 170W I doubt it.
[15:07:47] <Jymmm> FinboySlick: or at least not something you would trust too much.
[15:07:56] <FinboySlick> Jymmm: I get that now... I figured I'd ask the guys who know that stuff first though.
[15:08:21] <Loetmichel> if you buy some chines stuff and open it you will get a nice laugh, though
[15:08:36] <Jymmm> FinboySlick: =)
[15:08:45] <FinboySlick> I see these picoATX PSUs within that sort of power range so I wondered.
[15:08:56] <Jymmm> FinboySlick: Sad that's also 10% of the cost of the laptop too.
[15:09:11] <Loetmichel> here a charger for a keychain cam: http://www.cyrom.org/palbum/main.php?g2_itemId=8991
[15:09:12] <FinboySlick> Jymmm: Not that sad in my case.
[15:09:28] <Loetmichel> one has to admit: the chines have cojones.
[15:09:33] <Jymmm> FinboySlick: 10% for a PS, yeah it is.
[15:09:34] <FinboySlick> You throw in a Quadro 2000 and fast SSD and a few upgrades and it.
[15:09:36] <Loetmichel> to sell something like this ;-)
[15:09:45] <FinboySlick> ... ups the ratio.
[15:10:05] <Jymmm> FinboySlick: and how long does the abttery last?
[15:10:19] <Jymmm> 48 minutes?
[15:10:35] <FinboySlick> Jymmm: Surprisingly good. I actually never got it below 50% in my current use.
[15:10:44] <FinboySlick> I estimate at least 5h.
[15:11:03] <Jymmm> O_o
[15:11:38] <FinboySlick> I don't typically have the laptop working that hard when it's on battery and it manages things well I guess.
[15:11:38] <Jymmm> A laptop that needs at 170W PS with a 9 cell battery lasts 5h???? I'm not seeign it.
[15:12:03] <Jymmm> maybe
[15:12:19] <FinboySlick> If I had it actually doing real work, it would probably devour the battery in an hour and a half.
[15:12:25] <Loetmichel> Jymmm: if the i7 cuts 3 cores and halves the clock in battery mode: why not?
[15:12:56] <FinboySlick> Jymmm: It also shuts down the nvidia video card and runs on the intel.
[15:13:52] <FinboySlick> It's definitely the nicest laptop I've had.
[15:14:01] <FinboySlick> All kinds of thoughtful goodies on it.
[15:14:32] <Jymmm> FinboySlick: If it can run THAT GOOD, why would it require a 170W PS. It just doens't makes sense.
[15:14:46] <FinboySlick> That likely I'll never use, like the wireless hdmi whatever.
[15:14:50] <Jymmm> 120W, 95W ok. But 170W
[15:15:56] <Jymmm> My Lenovo laptop will run on 9VDC, but it won't charge till 15.1VDC, and comes with a 20VDC PS. It's just weird.
[15:18:07] <Loetmichel> Jymmm: horray for widerange SMPS ;)
[15:18:48] <Loetmichel> the internal Swtichers can step the 9V up and down to the needed voltages
[15:19:13] <Loetmichel> but the battery is charged directly from the psu input
[15:19:30] <Jymmm> No, I used a bench test PS, not a PC PS
[15:19:35] <Loetmichel> so the batter can only be charged if the voltage there is higher than the battery voltage
[15:19:50] <Jymmm> The battery is 12VDC
[15:19:53] <Loetmichel> Jymmm: the INTERNAL SMPS in the Notebook
[15:20:02] <Loetmichel> i dont think so
[15:20:10] <Jymmm> It says right on the label
[15:20:42] <Loetmichel> its either 10,8V or 14.4V
[15:20:56] <Loetmichel> or is it a PB battery?
[15:21:08] <Loetmichel> (HOW old is the laptop? ;-)
[15:23:03] <tom3p> your Smithy config directory has a load of goodies, eg add an MPG to a 5i20 ( see Naiky.hal); f
[15:23:08] <tom3p> or laser based tool setter, see Keyence files.
[15:23:09] <tom3p> and what was ez-trol anyaways, a custom Smithy-linuxcnc front end? http://www.youtube.com/watch?v=DkFLhIU0SCw
[15:23:28] <tom3p> i just used the NAIKY as a model for my Fanuc MPG, works great
[15:26:23] <JT-Shop> dang it was a shu-shu
[15:26:32] <andypugh> Hmm?
[15:26:52] <Loetmichel> oh MAN! i am lucky my wife is in GB at the moment... i (thoughtless) lit my cigarrette in the workshop (= part of the appartment) instad of gount on the balcony...
[15:27:13] <Loetmichel> THAT would have got me in truible if she was here ;-)
[15:27:31] <skunkworks__> eztrol was a closed front end to linuxcnc.
[15:27:40] <FinboySlick> Blackmail material.
[15:27:57] <Loetmichel> FinboySlick: dont think so
[15:28:28] <Loetmichel> 'cause: as long as nothing angers her nose on friday when she comes back everything is fine
[15:28:49] <djdelorie> blow up a few capacitors and resistors to hide the smell? ;-)
[15:29:34] <Loetmichel> djdelorie: just open the balcony doors on both sides of the house
[15:29:40] <Loetmichel> the wind does the rest ;-)
[15:29:48] <tom3p> skunkworks ah, it looked like it was hooked to the Synergy cad system
[15:30:18] <skunkworks__> actually - I remember something about that... It could have been
[15:33:22] <tom3p> anyway i just wanted people to now, browsing the code body, even the configs, shows up a lotta cool stuff
[15:33:28] <tom3p> know
[15:34:03] <tom3p> and thx to the Smithy guys ( Ray & Jeff i spose are in there )
[15:35:47] <skunkworks__> neat
[15:38:57] <skunkworks__> also matt
[15:50:26] <FinboySlick> Anyone familiar with the Emco Compact 5 ?
[15:51:00] <FinboySlick> Wondering if it can be had in north america... Or if there's an equivalent.
[15:51:00] <tom3p> i meant matt (doh!)
[15:51:12] <cradek> I think they have ballscrews and are kind of cool
[15:51:21] <cradek> teeny tiny ballscrews
[15:51:34] <FinboySlick> They seem very nice.
[15:51:50] <FinboySlick> And just the right size for me.
[15:52:16] <tom3p> emco maier is from novi michigan
[15:53:17] <tom3p> make that 'also from'
[15:55:20] <andypugh> Not ballscrew, going ny the pictures: http://www.ebay.com/itm/Emco-Compact-5-lathe-with-milling-accessory-extras-made-in-Austria-Free-Shipping-/251039723482
[15:56:09] <andypugh> But here is/was a Compact 5CNC: http://www.lathes.co.uk/emco/page11.html
[15:57:36] <cradek> andypugh: that's not a cnc - I'm pretty darn sure the cnc one is ballscrew
[15:58:04] <andypugh> cradek: Second link?
[15:58:18] <DJ9DJ> gn8
[15:58:29] <cradek> first
[15:58:36] <Thetawaves> hip hip horray! i've got two job offers
[15:58:38] <cradek> the 5PC is cool
[15:58:50] <cradek> all you need is an XT to run it
[15:59:20] <andypugh> I am vaguely thinking of making an Emco style toolpost for my lathe.
[15:59:23] <cradek> weird - that's not an XT keyboard
[15:59:49] <andypugh> But then it would be a cheap, rubbish, Chinese lathe with even more time and money thrown at it.
[16:00:11] <andypugh> cradek: Your geekiness is showing
[16:01:05] <cradek> :-P
[16:03:23] <andypugh> I feel under-intellectual. EBo is talking about "higher order osculants" and I am tallking in terms of "jerk the accel down if you are about to miss the endpoint"
[16:11:19] <cradek> if it helps, I have no idea what he's talking about either
[16:11:45] <andypugh> It does help, because you ahve actually written a trajectory planner.
[16:11:45] <cradek> on the other hand, he's talking while you're writing code
[16:12:20] <andypugh> talking of which, is t * t * t a sensible way to cube?
[16:12:39] <cradek> yes many people have talked about writing planners, while my code has been making machines run for years
[16:12:50] <cradek> looks sensible enough to me
[16:13:03] <JT-Shop> :-)
[16:14:56] <cradek> yishin is the first one who's actually presented code for testing and seems interested in getting it working right
[16:16:43] <andypugh> I need to get into the habit of typing "if (". I always have to go back and bracket the condition.
[16:17:36] <cradek> if, if(, and (if all show up in languages I use...
[16:17:58] <cradek> thankfully I can usually avoid if {
[16:18:13] <andypugh> if { would be?
[16:18:18] <cradek> tcl
[16:18:22] <andypugh> Eeew
[16:18:55] <andypugh> Hmm, what is actually required, in C, in if (cond=1) {z = pi ;}
[16:19:07] <andypugh> I think I can drop at least some of {;}
[16:19:17] <cradek> you can lose the {}
[16:19:28] <cradek> you might mean cond==1, but not necessarily
[16:20:34] <andypugh> Ah, yes, I do that a lot too. Luckily the compiler politely suggests that I might want to parenthesise the assignment used as a condition. (rather than saying "you idiot, this isn't BASIC"
[16:31:01] <asdfasd> hi guys
[16:31:13] <andypugh> Hi
[16:32:03] <JT-Shop> I'm sure I could turned those two flat head bolts from 3/4" bar stock faster than it took me to make a die and hot forge them...
[16:32:46] <andypugh> JT-Shop: True, but the texture would have been wrong.
[16:33:03] <JT-Shop> yes the top of the head would not look cannon-like
[16:33:36] <JT-Shop> I did get some great experience in forging 101 today
[16:35:08] <andypugh> 101?
[16:35:40] <JT-Shop> hmm a primer class like school...
[16:35:59] <JT-Shop> but it was the school of hard knocks I went to
[16:37:28] <andypugh> Ah, I thought it was some sort of metal alloy grade.
[16:41:46] <andypugh> Argh! Sombody on the internet is wrong! http://answers.yahoo.com/question/index?qid=20061104024241AA5YISI
[16:41:55] <andypugh> And it is 6 years too late to fix it.
[16:43:17] <JT-Shop> crap
[16:44:09] * JT-Shop goes to wander around at Caswell coatings for some plating material
[16:47:26] <andypugh> The "EN" in "EN8" is "Emergency Number" not "Euronorm". The confusion comes from the fact that all British Standards are now BS EN (which is a Euronormed British Standard). The EN-numbered steels are a set of standard alloys from WWII, which rather stuck, despite being abandoned in the 1980s. For example EN24 is now 817M40 and that would be SAE 4340 in the US.
[16:47:51] <JT-Shop> I see
[16:48:34] <andypugh> (I had to look up the US number on www.matweb.com )
[16:49:31] <JT-Shop> dang brass plating kit doesn't come with a power supply http://www.caswellplating.com/electroplating-anodizing/brass-plating-kits/brp265.html
[16:52:08] <andypugh> brass plating is evil and wrong. :-)
[16:52:22] <JT-Shop> why do you say that?
[16:52:26] <ds3> how does one plate brass? thought you cannot plate an alloy?
[16:52:46] <andypugh> Because it is purely a way to pretend that something is made from something it isn't.
[16:52:47] <JT-Shop> brass plate steel
[16:53:32] <JT-Shop> well sometimes it works out better to plate steel rather than paint it
[16:53:52] <andypugh> So use chrome or nickel, a functional plating.
[16:54:10] <andypugh> Or use solid brass.
[16:54:14] <JT-Shop> it wouldn't look right
[16:54:30] <JT-Shop> could not find solid brass acme nuts and screws
[16:54:46] <andypugh> You might have to make then, it's true.
[16:54:48] <JT-Shop> the rest could have been made from brass
[16:55:13] <andypugh> Though I think that the elevation screw would have been wrought iron.
[16:55:38] <djdelorie> brass? or bronze? which is better for high-wear surfaces?
[16:56:08] <andypugh> Bronze, generally.
[16:56:11] <JT-Shop> yes, I think the elevation screw was made from iron
[16:57:54] <JT-Shop> hmm bronze plating kits are 1/2 the cost of brass plating kits
[16:58:45] <JT-Shop> anyhow I just want to put a tiny bit of bling on it :-)
[17:07:55] <elmo401> bling sells better, too
[17:18:13] <ThadiusB> Hey everyone. When I load a file to be cut into Linuxcnc, it shows the apparent dimensions, however they are way off from what the machine physically cuts. For instance, have a part thats 5inches, reads as such in linuxcnc but when i goto cut it goes way beyond that. I dont recall messing with anything, it only recently started happening.
[17:20:46] <cradek> sounds like your scale (steps per inch) is wrong
[17:21:09] <cradek> either you changed those settings or something about your hardware, perhaps microstep settings
[17:21:45] <andypugh> Could be a jumper or DIP switch on the drive.
[17:22:07] <andypugh> Or a visit from the metric leadscrew fairy.
[17:22:26] <cradek> how far is it off? if it's a factor of 25.4 then it's just a gcode problem
[17:22:33] <ThadiusB> way off
[17:22:38] <cradek> haha
[17:22:41] <cradek> can you be more specific?
[17:23:08] <ThadiusB> well I didnt measure exactly, but a five inch part roughly has my machine traveling in excess of double the distance
[17:23:13] <djdelorie> it is bigger/smaller "off", or "not where I told it to be" off ?
[17:23:30] <cradek> you should probably measure it
[17:23:33] <andypugh> Not exactly double the distance?
[17:23:44] <cradek> incremental jogs and a dial indicator are good for that
[17:24:52] <ThadiusB> i'll check the jumps on my drive, and double check in the ini, and of course get a measurement as well
[17:26:29] <ThadiusB> quick question before i head out to the shop, between driver settings for full 1/2 1/4 or whichever on Microstepping, does linuxcnc need to coincide, or set to zero?
[17:27:38] <andypugh> No, you can just re-home. It doesn't matter what random units historical steps were in
[17:28:04] <ThadiusB> ty

[17:59:58] * JT-Shop still can't figure out what Andy said...
[18:09:16] <archivist> I like the last line "Well if you don't gloat whats the point!?"
[18:11:48] <JT-Shop> lol
[18:13:25] <archivist> but he has used the ide port in a way not intended
[18:15:13] <JT-Shop> archivist: I just had to dress up a tiny thread on a model steam engine and my needle files looked like giant files under the microscope... what do you use to file tiny things?
[18:15:45] <archivist> tiny files :)
[18:16:29] <skunkworks__> logger[psha]:
[18:16:29] <logger[psha]> skunkworks__: Log stored at http://psha.org.ru/irc/%23linuxcnc/2012-04-30.html
[18:16:39] <Tom_itx> can't believe rue's site made a post here :)
[18:16:58] <archivist> the normal needle files are a bit big, watch and clock making ones are available in smaller sizes
[18:17:07] <Tom_itx> that made it on hackaday btw
[18:17:20] <skunkworks__> I saw it on cnczone
[18:18:45] <archivist> JT-Shop, crap website but the files are good http://www.vallorbe.com/Standard.php?p=510&m=4&l=3
[18:21:47] <JT-Shop> archivist: thanks
[18:22:01] <archivist> JT-Shop, I also got some second hand files from clock fairs etc
[18:22:28] <JT-Shop> not much of that going on in my neck of the woods :-)
[18:24:12] <archivist> one thing clockmakers do is be careful what the files are used for
[18:25:11] <JT-Shop> so not to damage them I assume
[18:25:31] <archivist> yup, getting a mirror finish with a pivot file is a bit of an art
[18:26:10] <archivist> really its part file and part burnisher
[18:26:57] <djdelorie> and part micro-hand-plane
[18:27:46] <archivist> JT-Shop, the smaller files are the "escapement files"
[18:29:09] <andypugh> Designed for baking into pies?
[18:29:45] <archivist> so a watchmakers escapement file should be ok for sharpening a gnats cock
[18:30:40] <JT-Shop> ok, I see now
[18:31:13] <skunkworks__> they need to be sharpened?
[18:32:01] <archivist> a "gnats cock" is a british standard small measure
[18:32:58] <JT-Shop> ok, mine are for sharpening the beak of Alaskan mosquito's

[18:36:31] <archivist> home brew burnisher is a bit of hss that you rub on an oilstone to get the lines side ways on the metal
[18:40:36] <djdelorie> in woodworking, a "burnisher" is something different - a mirror smooth bit of extremely hard steel you use to turn an edge on a scraper.
[18:40:50] <djdelorie> stupid words. Mean one thing already! :-P
[18:40:53] <r00t4rd3d> http://www.ebay.com/sch/jtg1969/m.html?item=160773149605&sspagename=STRK%3AMEWNX%3AIT&_trksid=p3984.m1439.l2649&_trksid=p4340.l2562
[18:40:58] <r00t4rd3d> ^^ very good ebayer
[18:41:04] <r00t4rd3d> if you need bits
[18:41:58] <r00t4rd3d> I ordered two bits and he send them in a case :)
[18:44:58] <andypugh> JT-Shop: Be cautios about buying an aftermarket seat: http://www.autoblog.com/2012/04/30/man-being-hard-on-bmw-for-20-month-erection/
[18:46:24] <andypugh> djdelorie: I think both tools are doing the same thing, being very hard and pushing metal about.
[18:46:43] <djdelorie> yup
[18:47:06] <andypugh> I think that agate burnishers are used in some other craft.
[18:47:15] <djdelorie> except that in woodworking, you never touch the burnisher with any kind of abrasive
[18:47:35] <djdelorie> the burnisher isn't the cutting tool itself, it's used to form the cutting tool
[18:47:38] <andypugh> Ah, yes, leatherwork.
[18:48:10] <djdelorie> one cheap source of WW burnishers are car engine valve stems
[18:48:32] <andypugh> Yes, but your woodworking burnisher doesmuch the same to the scraper as the watchmaking one does to the pivot.
[18:49:02] <JT-Shop> he just needs to go to McDonalds and spill some coffee on his problem...
[18:49:23] <djdelorie> andypugh: really? It sounded like a watchmaker's burnisher is a miniature file
[18:49:24] <archivist> pivot file in use http://www.youtube.com/watch?v=1s-VVfda1ns
[18:49:28] <Tom_itx> then sue McDonalds for having hot coffee
[18:50:30] <archivist> the file has a cutting end and a burnishing end
[18:51:11] <JT-Shop> the bow is cool
[18:51:28] <JT-Shop> didn't they use something similar on early lathes
[18:51:34] <Jymmm> It's McDonald's "Hot Coffee" all over again... http://www.cbsnews.com/8301-504763_162-57423319-10391704/nutella-health-claims-net-$3.05-million-settlement-in-class-action-lawsuit/?part=webmd-cbsnews
[18:52:09] <archivist> I hate doing it on a support like that as the support can act as a grinder screwing your new surface
[18:52:53] <JT-Shop> from the chips?
[18:53:01] <djdelorie> WW burnishers are used to bend over a sharp edge: http://woodgears.ca/scraper/burnishing_angle.png
[18:53:12] <djdelorie> they don't cut or polish, they just push
[18:53:27] <Tecan> http://www.dalkescientific.com/writings/diary/archive/2007/06/01/lolpython.html
[18:54:41] <andypugh> djdelorie: I think that the clock pivot burnisher is mainly pushing metal about to make a smooth and hard surface.
[18:55:06] <archivist> JT-Shop, yes
[18:55:07] <djdelorie> that sounds plausible, unless there's polishing compound involved
[18:55:10] <andypugh> Smearing out the cut-marks from the file
[18:55:40] <djdelorie> it *sounded* abrasive in that video. WW burnishers are nearly silent
[18:56:21] <djdelorie> maybe "burnishing" is a class of operations, not a specific one. Stupid English! ;-)
[18:59:06] <toast2> burnishing is a metal forming operation that causes the surface irregularities to flow into one another
[18:59:19] <toast2> andypugh is correct
[18:59:34] <toast2> i.e. the high points get crushed and fill in the nearby low areas
[18:59:48] <Tecan> is modbus ethernet based ?
[19:00:56] <PCW> can be
[19:01:57] <PCW> can also be async serial

[19:06:46] <Tom_itx> not boeing surplus?
[19:07:02] <Jymmm> Tom_itx: Where's that located?
[19:07:04] <Tom_itx> i guess that's in seattle
[19:07:09] <Tom_itx> we had one here for a while
[19:07:18] <Jymmm> ah, no in San Jose
[19:07:31] <Jymmm> It was the LAST industrial surplus place around too.

[19:16:40] <Tom_L> that's the one i have
[19:16:49] <jdhNC> me too, so it must be good.
[19:17:16] <ReadError> what kinda jitter you getting?
[19:17:19] <Tom_L> http://www.newegg.com/Product/Product.aspx?Item=N82E16811154091
[19:17:23] <Tom_L> with that box
[19:17:26] <Tom_L> psu included
[19:18:06] <andypugh> D525MW is about 6k jitter
[19:18:20] <r00t4rd3d> is that bad?
[19:18:27] <jdhNC> I can get mine higher than that.
[19:18:29] <asdfasd> are these boards suitable for driving motors via LPT, if the video is integrated?
[19:18:30] <andypugh> It's excellent
[19:18:43] <andypugh> asdfasd: Yes, absolutely
[19:18:53] <Tom_L> i'd suggest mesa cards though
[19:18:57] <r00t4rd3d> i fking buying one
[19:19:32] <andypugh> Tom_L: Aye, so would I, but only really because 25 pins isn't really enough.
[19:19:41] <ReadError> r00t4rd3d; you finished the cnc router?
[19:19:43] <Tom_L> yup
[19:20:01] <jdhNC> I'm only using 24 pins on my yi43
[19:20:11] <Tom_L> so far
[19:20:44] <JT-Shop> yep I have a D525MW and get sub 10k latency... nice compact board
[19:20:55] <Tom_L> add a pendant, touch probe, coffee maker timer....
[19:21:09] <JT-Shop> hey your good to go then
[19:21:10] <jdhNC> can you use a mesa3x20 in linuxcnc?
[19:21:34] <PCW> Yes its supported
[19:22:04] <PCW> not that it makes a lot of sense
[19:22:17] <ReadError> so lower latancy = faster cuts with less lost steps?
[19:22:29] <r00t4rd3d> ReadError, not yet. Close.
[19:22:38] <ReadError> 1 of Aluminum 6061-T6511 Square Bar, AMS QQ-A-200/8, ASTM B221, 1" Thick, 1" Width, 36" Length $20.35

[19:23:00] <ReadError> awwwwwwww yea
[19:23:08] <r00t4rd3d> I need one more paycheck to get it going and finally be able to cut and try to cut something
[19:23:12] <asdfasd> Im asking for the shared video because I read that: Many onboard video chips cause bad realtime performance. The ones that use some of the system RAM for video ("shared memory") are the worst
[19:23:15] <ReadError> pics r00t4rd3d?
[19:23:19] <asdfasd> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Hardware_Requirements
[19:23:25] <Tom_L> ReadError you should visit my scrap yard
[19:23:27] <r00t4rd3d> i dont have any new ones atm
[19:24:07] <PCW> I think that (local RAM video causeing high latency) used to be true but is no longer true
[19:24:19] <roycroft> so i got the kiln today - it's gonna work out fine
[19:24:25] <ReadError> i figure the aluminum bar will last me a while
[19:24:28] <roycroft> it doesn't have a thermostat, but it has a duty cycle timer
[19:24:31] <roycroft> and a pyrometer
[19:24:39] <ReadError> i can cut it in to segments
[19:24:44] <skunkworks__> pcw: that is what I am seeing also.. (onboard video not causing problems)
[19:24:48] <roycroft> so i will run it at 100%, and when it approaches the temp i want i can dial it down
[19:25:02] <roycroft> and adjust it so that it holds the temperature i want, so i can soak big pieces
[19:25:04] <skunkworks__> *on newer motherboards
[19:25:29] <asdfasd> that is nice then...
[19:25:54] <PCW> Probably older shared RAM video was a bandwidth bottleneck but DDR SDRAM has enough to go around
[19:27:02] <asdfasd> I tried several boards (a bit old, but DDR) with integrated video they dont work with mach3
[19:27:15] <asdfasd> but I didnt have a chance to try many with emc2
[19:28:35] <PCW> you probably wouldn't know until you run the latency test as its video driver related as well
[19:29:35] <PCW> but both the Atoms and the Hudsons seem to be fine with integrated video
[19:29:43] <shdhdfghd> If you have it you can try but if you are looking to buy.... then it will be a risk
[19:30:43] <andypugh> ReadError: Lower latency = lower step-rate granularity. It's rare to run out of absolute stepper speed (except with enormous numbers of microsteps) but at high step rates you might be asking for instantaneous 20% speed increases between 5-thread-cycles-per step and 4-thread-cycles-per-step. A hardware generator (Pico or Mesa) has megahertz rather than khz base frequency.
[19:32:32] <PCW> if brute computing performance is not an issue, the Atoms seem pretty reliable latency wise (someone just posted the latest Atom 2800 numbers and they looked good as well)
[19:35:10] <PCW> The Intel Atom motherboards I should say (at least there seems to be more experience the the Intel MBs)
[19:35:37] <Tom_itx> i think they're price popular
[19:36:16] <JT-Shop> and fit in a bread box
[19:37:14] <Tom_itx> i put a backup server on mine
[19:37:49] <Jymmm> PCW: Intel brand or intel chipsets?
[19:38:01] <PCW> intel brand
[19:38:36] <Jymmm> My biggest gripe with intel barand desktop boards is they ALWAYS limit ram capacity.
[19:38:45] <A0Sheds> we are starting to use Gentoo + Linuxcnc + AMD APU's for everything
[19:39:59] <Jymmm> PCW: I kinda like alex4nder's thin atom mbo, but I also like this http://www.newegg.com/Product/Product.aspx?Item=N82E16813153212
[19:40:05] <A0Sheds> memleak is working on a Gentoo + RTAI + Linuxcnc install script, should be posted sometime soon
[19:40:18] <andypugh> Jymmm: But then LinuxCNC doesn't need much RAM, at all.
[19:40:35] <PCW> the dn2800t looks nice power wise (~10W) a noticeable improvement on the d525
[19:40:39] <ReadError> anyone compiled custom modules for the RTAI kernel?
[19:40:46] <ReadError> ive only done kernels from scratch
[19:40:54] <ReadError> not this .deb jibba jabba stuff
[19:41:19] <andypugh> ReadError: define "custom modules"
[19:41:23] <Jymmm> andypugh: No, but cad/drawing does.
[19:41:24] <ReadError> wifi
[19:41:35] <ReadError> no standard module compiled
[19:41:56] <andypugh> Ah, kernel driver modules?
[19:42:05] <andypugh> Yes, but really no.
[19:42:39] <ReadError> i figured i could DL the source
[19:42:43] <ReadError> patch, rebuild
[19:42:45] <jdhNC> I just pulled up a web page and all the ad links have that mini-itx case tom posted
[19:42:48] <ReadError> but jeeze thats a PITA
[19:42:59] <andypugh> Well, that's not really "custom"
[19:43:21] <andypugh> I thought you meant writing the driver from scratch :-)
[19:43:35] <ReadError> no
[19:43:40] <ReadError> but its not compiled for this kernel
[19:43:53] <ReadError> aka, no precompiled binary/module
[19:44:02] <andypugh> That shouldn't be all that hard then. Is there a makefile?
[19:46:17] <andypugh> This motion planner looked really hard until I tried to make it move at negative velocities, then all my maths breaks down.
[19:49:50] <PCW> Ah theres a d525 follow on: D2700MUD
[19:50:29] <PCW> also d2800 based so a little lower power and perhaps a little faster
[19:53:10] <PCW> also Intel MAC like the DN2800MT which is nice
[19:53:36] <andypugh> MAC?
[19:53:48] <PCW> Ethernet
[19:54:08] <PCW> Media Access Controller
[19:54:29] <andypugh> Ah, OK. Could be useful. ;-)
[19:55:08] <PCW> looks just like an updated D525
[19:55:57] <PCW> http://www.mo-co-so.com/Intel-D2700MUD-Mount-Union-DVI-Mini-ITX-Motherbo-p/mcs-int-mud.htm
[19:57:29] <Jymmm> PCW: http://www.amazon.com/Intel-BOXDN2800MT-Desktop-Board-DN2800MT/dp/B006XFIK08
[19:57:40] <Jymmm> PCW: Runs on 8-19V directly
[19:58:05] <andypugh> Now that's a big win
[19:58:13] <Jymmm> and half height
[19:58:33] <Jymmm> thank alex4nder for that find, and he says he's getting 5000 jiter on it
[19:59:27] <PCW> also lower power and a little faster than the previous Atoms
[19:59:39] <andypugh> r00t4rd3d: That one Jymmm just posted will save you the price of a PSU
[19:59:59] <Jymmm> r00t4rd3d: http://www.amazon.com/Intel-BOXDN2800MT-Desktop-Board-DN2800MT/dp/B006XFIK08
[20:01:13] <Valen> sounds like it wants to be a carputer
[20:01:37] <Jymmm> car, embedded, custom application, vesa mounted, etc
[20:01:58] <Valen> outside a car a regulated 12v supply is easy to come by
[20:02:03] <Valen> generally
[20:02:26] <PCW> too bad they wont run on 24V
[20:02:30] <Jymmm> Valen: 8-19VDC, who cares, just grab one and 80% would work =)
[20:02:32] <andypugh> It would be an unusual CNC machine without 12V
[20:02:45] <Jymmm> andypugh: 24 instead of 12 maybe
[20:02:51] <djdelorie> there's no 12v in mine
[20:02:56] <Valen> andypugh: though would you hook the controller to that 12v? ;->
[20:03:04] <andypugh> My touchscreeen needs 12V
[20:03:17] <Jymmm> andypugh: It has LVDS connector too
[20:03:24] <djdelorie> 120v, sure, but no 12v...
[20:03:48] <Jymmm> eh 24 to 12 step down pcb, easy enough
[20:04:43] <Jymmm> hell 24 to 19 if it's adjustable =)
[20:06:54] <r00t4rd3d> i dont see a parallel port
[20:07:03] <r00t4rd3d> does it have a header for one i guess?
[20:07:08] <PCW> it has a header
[20:07:11] <Jymmm> r00t4rd3d: It's on a header on the mobo, along with two serial ports
[20:07:58] <andypugh> I think I want to withdraw my previous statement.
[20:08:02] <Jymmm> there is also a connector on the mobo for internal power connection if you dont want to use the external coax connector.
[20:08:17] <Jymmm> andypugh: whys that?
[20:08:31] <PCW> if you have (and have room for) a standard PS the D2700MUD may make more sense
[20:08:46] <andypugh> I was making a statement about all CNC controllers, despite limited experience of any but my own.
[20:09:03] <Jymmm> andypugh: oh, and the logs never lie. You said we have proof! =)
[20:09:12] <andypugh> I have a PicoPSU in mine, but that needs 12V
[20:09:49] <Valen> andypugh: 12 or 13?
[20:10:18] <Jymmm> Valen: My PicoITX want 12V, no battery to charge.
[20:10:36] <andypugh> 12V but I don't think it is particularly fussy
[20:12:01] <andypugh> Hmm, I think I need to consider both roots of this quadratic equation, for both possible jerk signs. That's a job for tomorrow then.
[20:12:11] <andypugh> Night all.
[20:12:18] <Valen> that sounds like the start of a bad porno
[20:12:24] <PCW> 'nite
[20:15:53] <r00t4rd3d> so what do you power that with, a 9v battery?
[20:16:44] <r00t4rd3d> I got some tenergy's and a battery holder that puts them in series and they output 12v
[20:17:09] <PCW> that would work (~1A)
[20:18:04] <r00t4rd3d> hmm
[20:20:09] <r00t4rd3d> im about to test my m10000
[20:20:24] <r00t4rd3d> and see what the latency test says
[20:20:42] <r00t4rd3d> it will probably say : GTFO!
[20:21:12] <r00t4rd3d> it runs windows 7 okay though
[20:22:22] <r00t4rd3d> i really hate ubuntu too
[20:22:39] <PCW> some earlier VIA MBs with Unichrome graphics were OK with LinuxCNC so maybe its OK
[20:22:41] <djdelorie> there's a zillion other linux distros, pick something else :-)
[20:22:53] <r00t4rd3d> thats what i got, unichrome
[20:23:20] <r00t4rd3d> djdelorie, Im not sure what im going to do for software yet
[20:24:07] <r00t4rd3d> so the live cd with everything i will have to suffer through
[20:24:29] <elmo000> why suffer?
[20:24:37] <r00t4rd3d> ubuntu sucks balls
[20:25:12] <elmo000> indeed
[20:25:27] <elmo000> so use Debian.
[20:25:39] <elmo000> apt-get emc :)
[20:31:29] <r00t4rd3d> whats the best way to do the latency test
[20:31:47] <r00t4rd3d> rm -f / ?
[20:32:20] <Tom_itx> run it from the menu?
[20:32:23] <roycroft> watch four hd pr0n films simultaneously
[20:32:54] <roycroft> while calculating pi to 10^17 decimal places
[20:33:36] <Valen> dd if=/dev/urandom of=/dev/sda bs=1M is much more effective r00t4rd3d
[20:33:53] <Valen> (note don't actually do that)
[20:34:06] <roycroft> oh, you're no fun anymore
[20:36:34] <r00t4rd3d> my nick is a lie

[20:50:55] <ReadError> joe9,
[20:51:01] <ReadError> want to shoot for like

[20:51:28] <joe9> readerror: where?
[20:51:45] <ReadError> can you get down by where i work?
[20:51:49] <ReadError> we stagger our lunch to keep ppl there
[20:51:56] <joe9> ok.
[20:52:00] <ReadError> but if i tell them like 1
[20:52:06] <ReadError> then ill lock it in
[20:52:11] <ReadError> but ill be on IRC in the morning
[20:52:22] <joe9> yeah, let's stick with 1pm.

[20:58:39] <pfred1> why is diesel more than everything else?
[20:58:49] <pfred1> I always thought diesel was less refined

[21:00:06] <r00t4rd3d> I went to Applications, CNC, Latency Test and click and nothing happen. Is there a log file or something I have to look at?
[21:00:24] <pfred1> when that well blew up in the gulf and filled the Atlantic ocean with oil i became suspicious about this whole oil is a limited resource conspiracy
[21:00:25] <r00t4rd3d> or does it run in the background, should i run from a term?
[21:00:33] <pfred1> r00t4rd3d check /var/log/syslog
[21:01:17] <pfred1> tail -f /var/log/syslog
[21:02:09] <pfred1> you should run that command from a term
[21:05:26] <r00t4rd3d> Im getting a APIC error, available but not enabled :/
[21:06:01] <pfred1> r00t4rd3d you think that is what is causing you problems?
[21:06:24] <r00t4rd3d> i dont see how but thats the error that comes up when i click the latency test
[21:06:41] <pfred1> nothing in syslog huh?
[21:06:48] <r00t4rd3d> yeah, thats it
[21:07:38] <r00t4rd3d> i think i seen something in the quickstart about apic
[21:08:01] <pfred1> well at least you have something to investigate now
[21:08:20] <pfred1> you can check /var/log/messages too but it is a lot like syslog

[22:36:02] <r00t4rd3d> pfred1, me?
[22:36:34] <r00t4rd3d> I read I should do a latency test to see if my computer was worthy
[22:36:46] <pfred1> r00t4rd3d yes when LinuxCNC starts it doesn't automatically load the RTAI kernel extensions only when yo udo something like latency test or start a front end does the module load
[22:39:39] <r00t4rd3d> so looks like this computer is gonna be no good
[22:39:58] <pfred1> r00t4rd3d unless there is a solution

[22:43:40] <pfred1> r00t4rd3d some stuff in Linux is a pain to setup but once you have set it up it'll run until the wheels fall off your PC

[22:44:25] <pfred1> least that has been my limited experience with Linux since 1995
[22:44:57] <A0Sheds> the wheels fell off my Linux box and it still works
[22:45:22] <pfred1> djdelorie I've heard tale told of Linux servers getting built into walls and for years no one even knows where they are but the ykeep on working

[22:48:33] <Jymmm> gas doesn't count.
[22:48:34] <pfred1> since a line guy moved in down the street its gotten better
[22:48:56] <pfred1> he is my favorite neighbor
[22:48:56] <djdelorie> Jymmm: nope, seven day supply of propane on-site
[22:49:16] <Jymmm> djdelorie: That's not the "natural" I was speaking of =)
[22:49:42] <Jymmm> djdelorie: as in organic
[22:49:47] <djdelorie> whole house generator, automatic switchover, UPS... the power *doesn't* go out for the servers.
[22:50:02] <pfred1> this is Jymmm --> http://www.google.com/imgres?imgurl=http://upload.wikimedia.org/wikipedia/en/5/57/Mr_Natural.jpg&imgrefurl=http://en.wikipedia.org/wiki/Mr._Natural_(comics)&usg=__k9EwJLQtAEhXWAblqyHEVMno5Vw=&h=145&w=200&sz=19&hl=en&start=1&zoom=1&tbnid=fCrws2jTHM75hM:&tbnh=75&tbnw=104&ei=8lqfT_nONOHa0QHEzciIAg&prev=/search%3Fq%3DMr.%2Bnatural%26um%3D1%26hl%3Den%26sa%3DN%26gbv%3D1%26tbm%3Disch&um=1&itbs=1
[22:50:07] <Valen> I reboot mine rather more often, security updates
[22:50:24] <Valen> but my servers are clustered, so theres no actual downtime ;->
[22:50:38] <pfred1> Valen I don't run any public servers
[22:51:57] <Jymmm> djdelorie: how many kw is the gen?
[22:52:02] <djdelorie> 17
[22:52:13] <r00t4rd3d> linuxcnc wont work on ubuntu 11 ?
[22:52:17] <Jymmm> djdelorie: just propane?
[22:52:28] <djdelorie> just propane

[22:53:06] <Jymmm> djdelorie: k. There's a tru-fuel kit for my Honda EU2000i I'd like to get, unleaded, NG, and LPG
[22:53:12] <Jymmm> tri-fuel
[22:53:20] <djdelorie> I don't have NG available here, and gasoline goes bad over time
[22:53:22] <r00t4rd3d> or 12.04 i guess its upto now
[22:53:27] <djdelorie> even with stabilizers
[22:53:50] <pfred1> diesel doesn't
[22:53:51] <Jymmm> djdelorie: Yeah, now you know why I want the kit =) Plus I now have 3x 20# tanks
[22:54:17] <djdelorie> mine's a 330
[22:54:35] <djdelorie> I think. Big horizontal "submarine" shaped tank.
[22:54:47] <pcw_home> r00t4rd3: did you fix your lapic issue?
[22:54:52] <Jymmm> djdelorie: Yep, I'm fully aware of it, been there, done that
[22:55:12] <Tom_itx> is it a good idea to run a shielded signal wire to your step and directon signals?
[22:55:16] <djdelorie> quiet, reliable, automatic power... worth every penny
[22:55:35] <Jymmm> djdelorie: As long as the gas man is on time =)
[22:55:43] <pfred1> I worked on a job where we built a data center for wall st. they weren't messing around they had 3 generators on site the size of freight locomotives and a room the size of a basketball court filled with racks of batteries
[22:55:46] <r00t4rd3d> pcw_home, nope
[22:55:52] <djdelorie> Tom_itx: on mine, I ended up putting a pretty small load resistor at the controller end of those, to absorb EMI
[22:56:06] <djdelorie> Jymmm: they need up to three days to refuel, hence the seven day supply :-)
[22:56:15] <Jymmm> pfred1: Sounds liek a typical DC to me
[22:56:24] <Jymmm> djdelorie: ah
[22:56:32] <pfred1> Jymmm an electrician burnt the place to the ground
[22:56:32] <pcw_home> r00t4rd3d: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?TroubleShooting#emc2_doesn_t_run_missing_lapic
[22:56:47] <r00t4rd3d> tried that, same
[22:56:59] <Jymmm> pfred1: There's a DC here, where the gens are on the roof
[22:57:08] <djdelorie> pfred1: best story like that was my dad's. He worked on a tugboat, was taking a class at the engine factory. They had seven or so boxcar-sized engines in a "cold standby" state for power backup, went from cold to online in about seven seconds.
[22:57:23] <pfred1> Jymmm no way could you have put these things on the roof they needed 3 foot thick concrete pads int othe ground
[22:57:34] <Jymmm> pfred1: if they dont have fire supression to put ot any fire, they fubared on the design.
[22:57:58] <Jymmm> pfred1: I have nfc how they do this crap sometimes
[22:58:04] <Tom_itx> djdelorie like a pulldown type setup?
[22:58:04] <pfred1> djdelorie hospitals have huge flywheels
[22:58:13] <pfred1> Jymmm we were building the place
[22:58:33] <djdelorie> Tom_itx: yes. I tried various resistors until I found one still big enough to leave a useful "high" level
[22:58:59] <Tom_itx> ok, i'll see how 'noisy' it is first
[22:59:09] <Tom_itx> 10k?
[22:59:12] <pfred1> Jymmm the electrician wanted 3 more months of solid work
[22:59:20] <Jymmm> heh
[22:59:27] <djdelorie> Tom_itx: I don't recall the value, it depends on what kind of a logic high you need
[22:59:32] <Tom_itx> yeah
[22:59:41] <Tom_itx> i'll be using 5v logic i think
[22:59:44] <pcw_home> smart drives use differential step/dir
[22:59:51] <Jymmm> pfred1: he got busted I hope
[22:59:55] <djdelorie> Mine is 5V logic, but a "high" is anything from 2.2v up
[23:00:11] <pfred1> Jymmm he might have I mean i heard it was an electrician so someone must have known who it was
[23:00:30] <pfred1> there was a garbage pile on the site and he fired it up
[23:00:40] <djdelorie> CMOS 5v logic might need 4v or more, for example.
[23:01:06] <pfred1> I thought 2.7 was a solid high?
[23:01:34] <djdelorie> pfred1: for TTL, sure. Modern ICs are CMOS. You need to read the spec for your controller.
[23:01:57] <pfred1> that is the problem they have with CPUs you can only lower thevoltage so much before you don't have enough ratio beat the S/N
[23:02:13] <Tom_itx> i've got some nice shielded aircraft wire i may use
[23:02:18] <djdelorie> right, but your controller might have an opto input, so it's current that matters, etc.
[23:02:28] <pfred1> Tom_itx twisted pairs
[23:02:33] <Jymmm> Tom_itx: teflon coated?
[23:02:44] <pfred1> that is how you beat noise
[23:02:49] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/emc/small_probe7_small.jpg
[23:02:49] <djdelorie> differential over twisted pairs is best, assuming your PC has that as output and your controller has that as input.
[23:02:52] <Tom_itx> Jymmm yes
[23:03:14] <Tom_itx> fine strand stranded shielded
[23:03:18] <pfred1> though shielding never hurts
[23:03:37] <Tom_itx> Jymmm also surplus :D
[23:04:24] <Jymmm> Tom_itx: Just a BITCH to strip is all =)
[23:04:40] <Tom_itx> takes some patience
[23:04:58] <Jymmm> or a $200 electric stripper =)
[23:05:02] <pfred1> sharp scissors and then it is all in the wrist :)
[23:05:19] <Jymmm> pfred1: not teflon coated
[23:05:22] <pfred1> yup
[23:05:31] <pfred1> teflon coated that is how yo udo it with scissors
[23:05:33] <Jymmm> jacketed I mean
[23:06:00] <pcw_home> some drives with OPTO inputs leave them uncommitted (no common) so they can be driven differentially
[23:39:52] <alex4nder> hey
[23:51:22] <Jymmm> ho
[23:51:57] <alex4nder> sup
[23:52:23] <A0Sheds> anyone looking for a wire edm unit?
