[02:05:17] <DJ9DJ> moin
[02:10:06] <archivist_> eric_unterhausen, people should put in bug reports imo
[03:05:09] <Loetmichel> mornin#
[03:37:37] <James628> Good morrning!
[03:39:19] <James628> I am struggling to load high number of and2 component. "loadrt and2 names=and2.0,and2.1......and2.24" alway fails. I use twopass option in ini file
[03:40:36] <James628> Is there any max. number of components that makes limitation?
[03:40:39] <kengu> morining
[04:44:38] * Loetmichel is on the third day of "steaming" instead of Smoking... being a bit agitated and doesent know where to put my hands... missing the "go out and light a cigarette" part... will make something to eat now to distract myself...
[04:53:03] <archivist_herron> as a non smoker...I dont feel your pain :)
[04:53:53] <Loetmichel> archivist_: you will have another addiction then ;)
[04:54:18] <archivist_herron> erm...books mebe
[04:54:36] <archivist_herron> or irc
[04:55:24] <archivist_herron> http://xkcd.com/386/
[05:11:53] <ReadError> e-cig or something Loetmichel?
[05:12:30] <Loetmichel> e-cig
[05:13:52] <Loetmichel> but while that helps with the nicotine addiction it doesent help with the hands remembering to lit a cigarrette and violently demanding to do so
[05:15:50] <James628> Could anybody give guidance how to "wire" two MPGs (one built-in, one wireless remote MPG) in HAL file? The main issue how to connect the two "scale" and "counts" signals together?
[07:30:41] <Jymmm> Is there any reason SS shim stock is so pricy, or could I be paying for brand name?
[07:39:42] <jdh> do you want 0.010" +/- 0.005" ?
[07:40:09] <Jymmm> Yeah, tolerance is no biggy, need to be FULL HARD though
[07:43:18] <jdh> do they make shim stock like that?
[07:43:36] <Jymmm> yeah
[07:45:10] <archivist_> skunkworks, the registration form asked for the recommending person on http://bbs.homeshopmachinist.net
[07:46:11] <archivist_> just got the moderated email as I typed that :)
[07:51:56] <Jymmm> jdh: Did you have something in mind?
[07:59:54] <Jymmm> Whats the "L" in 304L?
[08:00:23] <Jymmm> This doesn't help "Type 304L has lower mechanical properties than Type 304"
[08:01:58] <jdh> heh
[08:02:30] <jdh> no suggestions. Most shim stock I have seen is made for precision.
[08:02:39] <skunkworks> archivist_: your good then?
[08:02:50] <jdh> otherwise it isn't shim stock, it is just thin stock.
[08:03:20] <archivist_> skunkworks, am now, seems to want to make the job hard though
[08:03:24] <Jymmm> jdh: Yeah, tolerance for this application isn't an issue is all I was saying.
[08:03:44] <skunkworks> archivist_: yeck
[08:05:06] <Jymmm> jdh: I just need the "springiness" of one sample I received, as another vendor's sample folded over big time.
[08:06:43] <Jymmm> jdh: And I have NFC on "finishes" either.
[08:07:10] <Jymmm> I think Andy knows this stuff pretty well.
[08:12:58] <archivist_> skunkworks, ok I replied :)
[08:19:12] <Tom_itx> Jymmm are you making stainless leaf springs?
[08:19:25] <Jymmm> Tom_itx: no
[08:24:18] <skunkworks> archivist_: can you post pictures of your bevel gears? or is that trade secrets? ;)
[08:25:02] <archivist_> they are not right yet
[08:26:04] <skunkworks> ah
[08:26:16] <skunkworks> righter than filing I bet...
[08:26:32] <archivist_> although that shows the form generation http://www.collection.archivist.info/archive/DJCPD/PD/2013/2013_08_16_bevel/IMG_1651.JPG
[08:27:13] <archivist_> filing will be crap, who has a really straight file in a filing machine
[08:28:46] <archivist_> I am rebuilding the cnc as the X was giving trouble
[08:33:01] <archivist_> currently contemplating the stacked rotaries and how they are mounted I wants trunnion equivalent
[08:33:32] <archivist_> but with an extra manual rotation
[08:34:35] <kengu> https://www.dropbox.com/s/6akx33r1ho075w9/20130918_002.jpg
[08:35:51] <cpresser> kengu: are those Co2-Laser-lens?
[08:36:08] <kengu> cpresser: yes. mirror and lens
[08:37:28] <cpresser> they look quite old. how much laser-hours were they used?
[08:40:22] <kengu> how could I tell. (umm.. is there a counter in linuxcnc?-). something every now and then in the last 6 months
[08:41:19] <kengu> or then I need to install a hour meter to some appropriate wire
[08:41:34] * cpresser has a hal component to track every program i run on the machine :)
[08:42:04] <archivist_> spindle/whatever hour meter comp needed :)
[08:42:43] <cpresser> take this man: http://pastebin.com/wGKJvB0b
[08:42:49] <cpresser> (or adapt it to your needs)
[08:44:52] <cpresser> used together with the hal-timer from the wiki: http://pastebin.com/6RsuXihq
[08:45:48] <cpresser> somewhere i also hava a perl script to parse the logfile. that way i can see exactly how much machining time i spend on a project
[08:45:54] <Tom_itx> to track machine time?
[08:45:56] <Tom_itx> i added a couple to mine
[08:46:20] <Tom_itx> one to track start to finish and another to track actual run time
[08:46:47] <cpresser> Tom_itx: my setup basically does the same
[08:47:45] <Tom_itx> should be in this config: http://tom-itx.dyndns.org:81/~webpage/cnc/configs/sherline/
[08:51:49] <Tom_itx> mine doesn't give total machine hours
[08:52:02] <Tom_itx> just per job time
[08:52:43] <cpresser> i hav an additional python-userspace-hal-comp which writes each job to a file. then i can sum then up
[08:57:58] <kengu> why do they have to use some arbitary units, http://www.engraversjournal.com/article.php/2780/index.html
[09:01:16] <jdh> what unit isn't arbitrary
[09:04:18] <Jymmm> hogshead
[09:06:32] <kengu> i think i need better exhaust fan for the laser
[09:08:20] <kengu> the duct is quite long and there is at the moment one that is rated for 777m³/h. It is possible to install another one of those as there are two outvents in the laser but then the ducts after the fans do need to be bigger or better or what ever
[09:08:35] <kengu> there is smoke
[09:08:40] <kengu> umm.. dinner time.
[09:08:55] <kengu> not related.
[10:15:45] <jmasseo> can linuxcnc drive a plasmacam machine?
[10:16:48] <jmasseo> I guess 'yes' to 'can' and 'no' to 'will out of the box'
[10:17:02] <kengu> ye
[10:17:03] <kengu> s
[10:17:31] <kengu> http://www.plasmacam.com/machspecs.php this?
[10:18:04] <jmasseo> yeah
[10:21:18] <jmasseo> i think it's a 'DHS'
[10:21:21] <jmasseo> DHC?
[10:22:04] <archivist_> seems to have its own controller
[10:22:18] <jmasseo> it's controlled over parallel
[10:22:30] <jmasseo> the 'machine controller' is more like a pendant
[10:22:49] <jmasseo> it's a smooth machine and it runs and cuts well
[10:22:53] <jmasseo> but the software is terrible.
[10:25:27] <cradek> before retrofitting your machine you probably want to install linuxcnc in simulator mode and work on the part of the problem where you convert your work (drawings?) to good compatible gcode
[10:25:50] <cradek> that seems like where you'd find any terribleness to compare :-)
[10:52:28] <JT-Shop> yuck, plasmacam must be messy without a water table
[11:59:11] <IchGuckLive> hi all B)
[12:03:00] <kengu> hi
[12:14:34] <jthornton> maybe it is a tuple in a list that I seek
[12:15:11] <jdh> seek and ye shall find.
[12:15:36] <jdh> unless it isn't there, then you just waste some time.
[12:25:53] <IchGuckLive> the USA is printing milions of dollar per second to keep yu folks running !
[12:31:49] <jdh> it's ok, we are buying worthless paper with the printed money.
[12:32:32] <jdh> nifty trick, isn't it. Especially if you are the one selling craptastic bonds to the fed.
[12:32:33] <IchGuckLive> Gov VAT said to use for industrial mashining
[12:33:45] <uw> gotta love the FED
[12:33:52] <uw> and whatever goes on in there
[12:33:55] <IchGuckLive> But the USA maybee loose one of its biggest trophy today to NewZeeland
[12:34:11] <uw> because thats right, nobody knows
[12:34:31] <uw> wht are we loosing to NewZeland?
[12:34:43] <kengu> i would say sailing
[12:34:49] <IchGuckLive> B)
[12:34:56] <jdh> nifty boats.
[12:35:02] <uw> oh that
[12:35:07] <IchGuckLive> 8:1 is the count it finishe to 9
[12:35:13] <jdh> I like the guys climbing the sails and slapping duct tape on them.
[12:35:17] <uw> yea as an american, i can assure you we dont care
[12:35:35] <IchGuckLive> its the hell of a raice
[12:35:37] <jdh> heh, I'm sure someone does
[12:35:40] <IchGuckLive> race
[12:36:16] <uw> thats true, IchGuckLive seems to care
[12:36:24] <uw> but something tells me he's not american lol
[12:36:28] <IchGuckLive> someone ever has linuxccn asked from NewZealand
[12:37:17] <uw> new zealand; hmm thats the country like "austraila's canada" right?
[12:37:36] <IchGuckLive> from Sf to wellington is not that Far bu you loose a hole day
[12:37:42] <kengu> depends on what is the canada
[12:37:55] <kengu> but well.. how much smoke there should be in my laser cutter
[12:38:11] <jdh> doesn't smoke attenuate the beam?
[12:38:27] <kengu> cutting some hdpe is causing a lot more smoke than acrylic
[12:38:45] <IchGuckLive> kengu: 100W
[12:38:58] <kengu> it surely is not helping.
[12:39:19] <kengu> 80W
[12:39:24] <CaptHindsight> kengu: is the exhaust fan running?
[12:39:45] <kengu> sure it is. or was and the smoke was going somewhere but slowly
[12:40:11] <kengu> there might be need for some more juice on that side
[12:40:49] <kengu> the smoke was inside the cutter. that is good
[12:41:12] <IchGuckLive> be aware of laser fire
[12:41:30] <IchGuckLive> not the first shop that woudt burn down
[12:41:38] <IchGuckLive> on China laser cut
[12:41:50] <IchGuckLive> homemade ore plug and play
[12:42:13] <kengu> umm.. this is not burning down. that is good
[12:42:55] <kengu> something might burn but pretty .. mm.. safe
[12:42:57] <kengu> ly
[12:43:28] <IchGuckLive> hi PCW
[12:43:42] <pcw_home> Buy low sell high
[12:44:05] <IchGuckLive> pcw_home: question what is the preferd resistor for the 7i76 out 24V to 5V optokoppler
[12:44:36] <pcw_home> depends on the current desired
[12:44:54] <IchGuckLive> i guess the optkoplers take 10mA
[12:45:37] <IchGuckLive> i need to reduce the head on mashine standing
[12:45:39] <pcw_home> so 5 ma would be about 4.7K
[12:45:49] <IchGuckLive> 2.2K
[12:48:32] <IchGuckLive> hi Einar all systems working
[12:49:26] <Einar> One PC seems OK now. Had to reinstall, recompile..... done.
[12:49:38] <IchGuckLive> :D
[12:50:23] <Einar> The other sort of. Latency Servo thread jitter is 500 000 - 1 000 000!
[12:50:48] <IchGuckLive> you did all the help
[12:51:43] <IchGuckLive> Einar: get you a mutch cheeper PC
[12:52:09] <Einar> It seems I have to go dumpster diving. :-)
[12:52:17] <IchGuckLive> agree
[12:53:58] <uw> anyone here ever make a 6 axis robot?
[12:54:11] <IchGuckLive> Einar http://search.eim.ebay.no/?elc=3&kw=fujitsu+5925&ect=
[12:54:12] <uw> (thats someone repeatable)
[12:55:00] <IchGuckLive> Einar: the 5915 is better for the Linuxcnc if you find one take them
[12:55:54] <Einar> I found this: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Latency-Test
[12:59:47] <Einar> As I understood it need not have exceptionally numbers when using the USC to issue the stepper pulses?
[13:00:56] <pcw_home> probably anything better than 50 usec or so latency should be OK
[13:03:30] <IchGuckLive> Einar: why are the norway people selling there older pc in parts not complete is ther no second hand market
[13:04:58] <IchGuckLive> the ibm A50 is worldwide sold and second IT as i use this PC for around 80Mashines and they work so glad
[13:05:20] <Einar> Uhh? I did'nt know that we do. Second hand market is low. Also because computers are so cheap here. One of the few things that are cheap in fact.
[13:05:21] <IchGuckLive> non in the scandinavian world
[13:05:48] <IchGuckLive> Einar: beer O.O
[13:06:08] <Einar> Is NOT cheap here!
[13:06:16] <IchGuckLive> i do know
[13:07:31] <IchGuckLive> you can get a full 20 bottle beer crate here in germany for less then ONE buttole in Olso
[13:07:42] <IchGuckLive> OSLO O.O
[13:08:02] <IchGuckLive> i think olso is also a Norway city :D
[13:08:49] <Einar> Then you had too many ..... ;-)
[13:09:05] <andypugh> I was initially more worried that you knew the price of buttholes in Oslo, then realised it was a typo.
[13:09:09] * roycroft brews his own beer
[13:09:16] <roycroft> cheaper and better than the commercial stuff
[13:09:56] <roycroft> some folks in my brew club moved to norway a couple years ago, though, and they say homebrew supplies are very hard to get in the scandanavian countries
[13:10:53] <Einar> I used to. Have to take it up again, because it was not just cheap, but better than most of the pi** you get in the shops.
[13:10:58] <IchGuckLive> roycroft: agree but you need to be came a long time after brew
[13:10:58] <roycroft> yup
[13:11:06] <Einar> HB supply have become good the last years, after it was allowed to DIY.
[13:11:28] <IchGuckLive> Einar: isent there the ligtning festival this days
[13:11:34] <roycroft> and i can brew stuff that's not available here, like kölsch or beliner weiße
[13:11:45] <roycroft> or things that don't travel well like bavarian hefeweizen
[13:12:31] <IchGuckLive> roycroft: its less then 2Days for the biggest beer fest in the world
[13:12:36] <kengu> andypugh: (:
[13:12:47] <roycroft> yes, i know
[13:12:53] <roycroft> and i brewed a märzen last march
[13:12:59] <IchGuckLive> the USA flights towards munich are expected tomorrow
[13:13:00] <roycroft> it's carbing now, and will be ready to serve by week's end
[13:13:11] <roycroft> i'm having a get-together here
[13:13:31] <roycroft> i'll have that, and a dunkelweizen that i just brewed, and a little maibock left
[13:13:43] <roycroft> and i mostly don't brew german styles
[13:13:46] <Einar> Is there any use in trying a Shuttle PC? I have a bunch of them.
[13:13:47] <jmasseo> i want a maibock
[13:13:50] <jmasseo> i've only had the spaten
[13:13:51] <IchGuckLive> also 8 Flights of austrailian girls are expected to arrive this weekend
[13:13:52] <roycroft> but for oktoberfest, one must
[13:13:52] <jmasseo> and it was divine
[13:14:06] <roycroft> the maibock is very nice and malty
[13:14:16] <jmasseo> the spaten is the only maibock i've ever had
[13:14:17] <roycroft> for those of you who know about homebrewing, i do triple decoctions for my bocks
[13:14:24] <jmasseo> labor intensive
[13:14:38] <andypugh> Einar: Boot from LiveCD and try the latency test.
[13:14:45] <roycroft> this all is not germane to the purpose of this channel, so if anyone is annoyed, i'll happily zip my lips
[13:14:56] <roycroft> but it's a labor of love
[13:15:11] <jmasseo> :)
[13:15:30] <roycroft> i don't decoct my bavarian hefeweizen/dunkelweizen, although i know several breweries in bavaria still do so
[13:15:33] <andypugh> To further digress, I managed to use the word "germane" to mean two different things in one sentence in my PhD thesis. :-)
[13:15:35] <roycroft> i should try that some time
[13:15:35] <IchGuckLive> in most Big citys in the USA there are good Beer stores with worldwide stuff
[13:16:15] <roycroft> how so, andypugh?
[13:16:18] <roycroft> it's a great word
[13:16:24] <roycroft> but i only know of one basic meaning
[13:16:26] <andypugh> http://en.wikipedia.org/wiki/GeCl4
[13:16:47] <roycroft> ah
[13:17:06] <cradek> Einar: is it related to http://www.linuxcnc.org/docs/html/man/man1/shuttlexpress.1.html
[13:17:10] <andypugh> Sorry, wrong compound: http://en.wikipedia.org/wiki/GeH4
[13:17:54] <roycroft> a rather obscure use of the word
[13:18:00] <roycroft> i never knew it as a noun
[13:18:46] <roycroft> if i were discussing the compound germane i'd surely find a way to use the adjective form in the same sentence
[13:18:54] <roycroft> it would be impossible for me not to do so
[13:19:06] <andypugh> Yes, I decided to not even fight the temptation.
[13:19:19] <Einar> cradek: No. It's a range of PC's: http://www.komplett.no/search?category=10149_Kabinetter%2FBarebone&q=shuttle
[13:19:27] <roycroft> and i'm not even british!
[13:19:35] <roycroft> it must have been even more compelling for you to do so than me
[13:20:27] <roycroft> subtle, clever wordsmithing is not appreciated on this side of the pond as it is in england
[13:20:29] <cradek> oh ok
[13:20:48] <andypugh> Einar: I am not seeing many parallel ports, or much scope for PCI cards.
[13:21:42] <Einar> Some of those (older ones) I have does have 1-2 PCIslots.
[13:22:01] <James628> Hi All, Could someone give guidance howto to connect signals from two MPGs in HAL file? I have one MPG built in, and second one is wireless MPG.
[13:22:51] <CaptHindsight> James628: what's on the PC side of the wireless MPG?
[13:23:15] <IchGuckLive> James628: http://www.linuxcnc.org/index.php/russian/forum/18-computer/26168-hal-file-to-enhace-mpg-pendant-usb-wireless
[13:23:26] <James628> CaptHindSight: and USB receiver
[13:24:13] <James628> this one: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Using_A_XHC-HB04_Wireless_MPG_Pendant
[13:25:23] <IchGuckLive> James628: this will conect the same way then our joypads
[13:25:52] <IchGuckLive> less /proc/bus/input/devices
[13:26:03] <IchGuckLive> look if the pc alredy good the divice
[13:27:21] <IchGuckLive> James628: http://www.youtube.com/user/magic33de look i made a video on this
[13:27:36] <James628> The wireless MPG is working correctly if there is no other MPG. But I have one built in in the control panel. I want to switch between the two MPGs
[13:28:21] <IchGuckLive> with a pysicle button or a virtual
[13:28:39] <James628> physical,
[13:29:24] <James628> with A and B signals going to the encoder input of Mesa 7i43
[13:32:19] <IchGuckLive> ok im off BY
[13:32:25] <andypugh> James628: No need to switch, just add the two encoders together in HAL.
[13:32:26] <IchGuckLive> Night here James628
[13:35:11] <James628> andypugh: I have this line: net jog-counts xhc-hb04.jog.counts , but then how to add the same counts input from the second MPG?
[13:37:43] <andypugh> loadrt sum2 // addf sum2.0.servo-thread // net jog-counts-1 xhc-hb04.jog.counts sum2.0.in0 // net jog-counts-2 xhc-hb04__2.jog.counts sum2.0.in1 // net jog-counts sum2.0.out
[13:39:00] <PCW> the hal file parser ought to expand + into that :-)
[13:39:57] <cradek> eviiiiil
[13:41:16] <andypugh> pin maths would be handy sometimes.
[13:41:24] <cradek> use ladder
[13:42:16] <andypugh> I was hoping to make the HAL file clearer, not opaquer.
[13:42:47] <cradek> heh well yeah
[13:43:57] <andypugh> What could I use a 150m range laser rangefinder (which requires a reflector) for?
[13:44:21] <jdh> visible laser?
[13:44:33] <andypugh> Infra-red
[13:44:39] <CaptHindsight> andypugh: alignment of really big machines :)
[13:45:53] <andypugh> One of these: http://www.kulttempel.de/elektronik-gesamt/pepperl-fuchs/pepperl-fuchs-visolux-entfernungsmessgeraet-edm-120-ssi-neu/a-4152/
[13:46:01] <andypugh> (I paid a lot less)
[13:46:57] <James628> andypugh: this is what should work ?: net jog-counts-1 xhc-hb04.jog.counts sum2.0.in0 # MPG no.1 // net joint-selected-count hm2_7i43.0.encoder.00.count sum2.0.in1 # MPG no.1 // net final-counts sum2.0.out => axis.0.jog-counts //
[13:48:16] <andypugh> Well, it looks OK, does it work?
[13:50:05] <James628> andy: I hope so, but it takes some time to change everything in HAL. I'll try.
[13:50:29] <James628> andy: thanks a lot!!
[14:04:37] <Einar__> One of the Shuttle PC's looks promising. Installing to HD .....
[14:12:31] <andypugh> This is fun: http://io9.com/5947112/watch-32-discordant-metronomes-achieve-synchrony-in-a-matter-of-minutes@bricken

[14:24:38] <Einar__> Strange you should point to that video. Just as I wonder why this PC sounds like a metronome! And it's not the HD.
[14:29:39] <Einar__> Max jitter is around 15 000 on both threads while watching The Fox on youtube and watching System Monitor. CPU usage=100.0% !!
[14:31:17] <Einar__> Looks like a good candidate if I can find a PCI parport. Tomorrow is Dumpster Diving Day. :-)
[14:34:15] <andypugh> If you can find a PCI parport, then use it. But I wouldn't buy one, the 5i25 is a much better bet for only about 4x the price.
[14:35:23] <Einar__> I have a USC on it's way.
[14:35:39] <JT-Shop> happyness is a sharp slitting saw
[14:35:55] <andypugh> Ah, in that case you need a parport.
[14:45:52] <JT-Shop> http://imagebin.org/271387
[14:46:10] <JT-Shop> quite fun to make them
[14:46:57] <Einar__> I already did the git clone to linuxcnc-dev. And I put it on a USBstick. Can I just pull it back from there instead of git?
[14:47:54] <andypugh> Yes, git archives are pretty portable.
[14:48:19] <cradek> Einar__: usb sticks rarely preserve filenames, permissions, owner, etc., because they are generally dos-related filesystems
[14:48:19] <andypugh> Einar__: But you might find the buildbot to be a lot easier
[14:48:28] <cradek> so it's really better to not do that
[14:49:40] <Einar__> OK. Then I'll do it exactly as it says in http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Installing_LinuxCNC
[14:49:47] <James628> andy: I made the changes in the HAL file, but jog-counts are s32 type, but sum2 is float type, so type mismatch... convert_s32_float could help?
[14:52:11] <andypugh> I popped home from work today to make a part for a test car. (I needed it in a hurry)https://picasaweb.google.com/lh/photo/zd_hdikVulibabqJdCcxltMTjNZETYmyPJy0liipFm0?feat=directlink
[14:52:31] <andypugh> All done on a lathe with a 4-jaw chuck.
[14:53:30] <andypugh> James628: Yes, though switching to float and back to int isn't a very nice idea.
[14:54:35] <JT-Shop> nice
[14:56:43] <James628> andy: I supposed that :) What else can I do?
[14:58:20] <andypugh> I am looking to see if any other components "acccidentaly" add s32 together
[15:01:03] <andypugh> You _could_ write a custom component to add the counts together. This would also be a way to arbitrate which axis jog-select switch was obeyed.
[15:02:03] <andypugh> I am imagining that it would look to see which jogwheel was moving and pass through the jog-selected from that encoder rather than the other.
[15:02:19] <andypugh> (otherwise I don't know how you will manage that)
[15:03:57] <James628> andy: Writing components is to complex for me. Could I take the sum2 component and just based on it create sum2_float comp?
[15:04:28] <cradek> do you both realize that it doesn't matter if the counts jump, as long as that wheel input is disabled?
[15:05:25] <andypugh> I am not sure I follow?
[15:05:43] <cradek> I assumed you were adding them together so you wouldn't get a jump when you switch between wheels
[15:05:54] <cradek> or do you really want them both active at the same time?
[15:06:07] <andypugh> I was trying to avoid switching between wheels, and leave them both active.
[15:06:13] <cradek> ah ok
[15:06:30] <James628> cradek: No, I use one MPG at a time, not in parallel..
[15:06:48] <andypugh> And aren't they disabled at destination rather than source, so the problem remains?
[15:07:04] <James628> I have switch button and LED for selecting between the MPGs
[15:07:08] <cradek> yes at destination
[15:07:25] <andypugh> So, how do you disable one and not the other?
[15:07:45] <cradek> you'd need to mux them as well
[15:08:07] <cradek> I didn't fully bake this idea
[15:08:53] <andypugh> James628: Do you _want_ to switch? If I was doing this I would try to leave both knobs active at the same time.
[15:09:23] <andypugh> (which is why I am suggesting adding them together)
[15:10:25] <James628> Andy: I would prefer to switch between them, just for the safety, if the remote one is not enabled explicitely, then noone can make some nasty things on it.
[15:10:47] <andypugh> For switching between them, you want mux_generic. But he only exists in Master :/-/
[15:11:59] <andypugh> Otherwise, it's mux2 and that also only does float.
[15:12:30] <James628> This will be a production machine, maybe better to stay with stable version
[15:12:33] <andypugh> (but creating an S32 variant is relatively easy)
[15:13:51] <kwallace> Has anyone used CSS with parting? I'm concerned about throwing a part when CSS gets to MAX RPM.
[15:14:19] <andypugh> Actively enabling the remote is one thing, but would you really want enabling the remote to disable the local?
[15:14:21] <James628> A picture of the machine: http://www.cnctar.hunbay.com/Varga%20Istv%e1n/Mar%f3g%e9p%205t/Burkolat%203.jpg
[15:14:49] <andypugh> kwallace: The G-code that turns on CSS lets you specify a max RPM
[15:15:23] <James628> Andy: you are right, the local can be enabled too.
[15:23:07] <James628> Thanks Andy for the hints. I have to leave. Bye.
[15:26:03] <kwallace> I had visions of letting CSS go to a highish RPM, then back off when the neck gets thin. The problem is that the g-code generator gets complicated because another set of entry boxes are needed. I'm trying to decide what is worth doing. Pecking gets into the mix too.
[16:21:21] <DJ9DJ> gn8
[16:41:29] <JT-Shop> well he didn't stay long
[17:34:12] <Tom_itx> nice shower passin thru
[17:40:02] <JT-Shop> we have 80% tomorrow
[17:40:41] <Tom_itx> narrow band but heavy for a bit
[19:18:58] <andypugh> Argh! After staring at the driver code for an hour, trying to work out why even though the driver is now stable and functional, I wsn't reading valid data from the encoder, I realised that it was because the encoder has a purple cable, not a blue one. And it was the blue one plugged in to the 7i76..
[19:19:39] <Tom_itx> woops
[19:32:46] <somenewguy> does anyone have expereicne trying to use linuxCNC on a modern laptop with a PCIE parallel port installed?
[19:33:41] <somenewguy> I have seen in the wiki that "laptops aren't good enough" but unless there are driver issues w/ the parrele card, I am translating that statement to be "laptops old enough to have a parallel port aren't good enough to run a mill"
[19:34:02] <somenewguy> and I know I need to make sure the card is actually parallel port, and not USB card emulating parallel
[19:34:03] <Tom_itx> all the power saving stuff should be shut off
[19:34:25] <Tom_itx> it's not a good combination
[19:34:53] <Tom_itx> have you run the live cd on it?
[19:35:08] <somenewguy> My reasoning is my NEWEST PC that I can spare for teh shop is a P4, so it is pretty dated
[19:35:26] <somenewguy> but I have an inspirion 6400 xfr that is iirc 3ghz dual core
[19:35:26] <Tom_itx> P4 might work ok
[19:35:29] <somenewguy> no, but I can do that right now
[19:35:34] <somenewguy> I havea p4, and it works ok
[19:35:42] <somenewguy> currently running Mach3 on windows
[19:35:53] <Tom_itx> still need to run a latency test
[19:36:02] <somenewguy> but whenever the CPU peaks, all the axis jitter, as if all the pins are pulsing at random till the processor calms down
[19:36:10] <somenewguy> I'll do that right now
[19:36:23] <somenewguy> I don't have the parallel card yet, but latency test is only testing the processor and system, right?
[19:36:40] <somenewguy> not the actual port
[19:36:48] <Tom_itx> i beleve so
[19:36:56] <Tom_itx> believe*
[19:38:11] <jp_mill_> hmm why is the analog signal pegged at 10v when i enable my drives?
[19:38:40] <somenewguy> I also want to get the parallel card so I can finally make that logic analyzer I want
[19:38:53] <somenewguy> already have a few buffer chips floating around, so why the heck not, you know?
[19:38:56] <Tom_itx> i got a Saleae
[19:39:04] <somenewguy> I have a logic analzyer, but it doesn't do realtime
[19:39:38] <somenewguy> I stumbled across that like 3 months after I finally bought mine, wish I had got it
[19:39:44] <somenewguy> or a buspirate
[19:39:57] <somenewguy> although the one I have was cheap enough, and it does work, just annoying it won't do realtime
[19:40:19] <somenewguy> ooooh man, i forgot the angry noises the CD rom on this laptop made
[19:40:44] <somenewguy> I refusee to admit steve jobs was right that we don't need media, but it has probably been since the last OS install that I actually popped a CD into this machine...
[19:45:25] <somenewguy> that answers that
[19:45:28] <somenewguy> miserable latency
[19:45:33] <somenewguy> 350mS
[19:45:38] <somenewguy> errr
[19:45:40] <somenewguy> 350uS
[19:48:37] <jp_mill_> andypugh: you around?
[19:49:31] <andypugh> I might be
[19:50:16] <jp_mill_> trying to figure out why one analog out on a 7i77 might be going full scale on start up
[19:51:31] <jp_mill_> http://pastebin.com/J5uPn6Ky
[19:51:52] <jp_mill_> x and y are fine but z axis pegs at -10V
[19:52:16] <jp_mill_> same tuning i used on with the 7i43 and 7i33
[19:52:23] <andypugh> somenewguy: The reason that laptops are normally bad is that they tend to have poor latency. Bear in mind that latency has _nothing_ to do with performance. Often older, slower, simpler machines will give the best latency. One all-time favourite for LinuxCNC was a cheap Intel Atom board.
[19:52:23] <PCW> check the scale
[19:53:17] <andypugh> jp_mill_: Can you look at the input to it too? Is it possible that is what the PID is actually requesting?
[19:53:19] <jp_mill_> Input,output?
[19:53:29] <jp_mill_> one sec
[19:54:07] <jp_mill_> pid command is 1.6e-6
[19:54:38] <jp_mill_> saturated = true
[19:54:49] <jp_mill_> output = -10v
[19:55:15] <andypugh> saturated=true is a strange thing at 1.6e-6
[19:55:33] <jp_mill_> yeah and error is low as well
[19:56:36] <PCW> what I would do to rule out a hardware problem
[19:56:36] <andypugh> I really don't see the value in hm2_[HOSTMOT2](board).. as a construction :-/
[19:56:37] <PCW> is test via halrun
[19:57:04] <PCW> it makes the hal file all the same
[19:57:34] <PCW> hm2-servo.hal is common to most FPGA cards
[19:57:54] <andypugh> Yeah. halrun // Loadrt hostmot2 // loadrt hm2_pci // setp hm2_5i25.0.7i77.0.1.analogout2 0 (and other values)
[19:59:10] <PCW> I would just setp the analogena true
[19:59:11] <PCW> if you get a full scale output then you have a bad 7I77 card
[19:59:55] <jp_mill_> guess i could just test a different output as well
[20:00:30] <PCW> I would try the halrun test to eliminat and possible hal file issues
[20:00:41] <PCW> eliminate any
[20:02:00] <somenewguy> does a MESA board offload the work the pc has to do, or does it only really give you more flexible and more numerous I/O pins?
[20:02:24] <PCW> Both basically
[20:02:42] <somenewguy> I have a couple of older PCs, and if I can throw $150 worth of hardware at it make it future proof for my machine, I would be pleased as punch
[20:03:11] <somenewguy> I currently have a 4 axis mill, but I intend to add cooling, motor speed control and as many tool homing/probing features as I can reasonably afford/justify
[20:03:13] <PCW> more I/O and fast hardware step generation /analog out/encoder counting
[20:03:37] <somenewguy> I am trying to browse the MESA site, but its mostly greek to me
[20:03:43] <somenewguy> I think alot of them are overkill for me
[20:03:52] <somenewguy> but I can barely tell
[20:04:05] <somenewguy> are there other well supported brands, or is MESA the be all end all?
[20:04:50] <PCW> Pico systems, Vital systems, Beagelboard...
[20:05:15] <somenewguy> dang
[20:05:23] <jp_mill_> hmm i got nothing
[20:05:30] <somenewguy> am I overdoing it? I feel like I am jumping in too fast here
[20:05:40] <somenewguy> I already have a full setup, I just need a reliable pc
[20:05:45] <Tom_itx> mesa has good support here
[20:06:01] <PCW> if you have a setup that can be driver from one or 2 parallel ports, a 5I25/6I25 may make sense
[20:06:09] <PCW> driven
[20:06:12] <somenewguy> better than the rest?
[20:06:22] <Tom_itx> i don't own the rest
[20:06:28] <Tom_itx> i just went with the best
[20:06:28] <somenewguy> haha
[20:06:41] <somenewguy> if mesa is the best, I am willing to spend a little more to not have to spend twice down the road
[20:06:52] <somenewguy> I currently have a 4 axis and a gecko 540
[20:07:15] <somenewguy> I don't even have homeswitches hooked up yet, but they should show up tomorrow
[20:07:18] <somenewguy> will make my life a lot better
[20:07:33] <somenewguy> a few less e-stops I hope, and the ability to reset from that damn jitter
[20:07:40] <somenewguy> i blame windows
[20:08:03] <andypugh> 5i25 + G540 is a good setup.
[20:08:10] <somenewguy> fingers crossed goign to linux fixes that, but if not then i probably need to revamp the whole PC
[20:08:21] * somenewguy quickly reads up some specs on the 5i25
[20:08:30] <Tom_itx> run the latency test beforehand
[20:09:08] <jp_mill_> PCW: what scale were you refering to?
[20:09:38] <PCW> mumble maxscale
[20:10:04] <somenewguy> what do thye mean when they mention "breakout cards"?
[20:10:05] <jp_mill_> would that chage from a 7i33 to a 7i77?
[20:10:16] <somenewguy> I already did a latency test, I don't remember what the numbers were but they were very good
[20:10:39] <somenewguy> well, I thought they were very good sicne it was such an old machine, but since apprently that is not how latency works, they were still quite good numbers
[20:10:47] <PCW> Yeah its somewhat different on the 7I77
[20:10:56] <andypugh> If the latency is good, and you have a parport, then try running like that.
[20:11:34] <somenewguy> I think it was 10-15uS, but it has that damn intermittent spaz in Mach3
[20:11:37] <somenewguy> yes it does have a prallel port
[20:11:41] <jp_mill_> PCW: ah whats different?
[20:12:01] <somenewguy> someday I will learn how to spell that word
[20:12:31] <andypugh> 15uS and a G540 is probably perfectly usable.
[20:12:46] <andypugh> Though I am another Mesa fan.
[20:13:21] <andypugh> It certainly makes sense to see how the setup you have works before deciding if you want to spend more.
[20:13:27] <PCW> Yeah a parallel port may work just fine if you are not pushing speeds to the limit
[20:14:34] <PCW> and who knows, you may find that you don't like linuxcnc (sacrilege I know)
[20:16:19] <andypugh> Right. that was a drive-by commit of a major reorganisation of the SSI driver. And now I am going to sleep. I am taking a long weekend, won't be back online until sunday.
[20:17:08] <PCW> jp_mill_: I would make sure that the three scaling and limit parameters per axis make sense (halcmd show parm | grep 7i77.0.1)
[20:17:23] <somenewguy> sounds good
[20:17:27] <Tom_itx> have a good one andypugh
[20:17:35] <somenewguy> heck for all I know there is a second parrallel port on the MOBO that I just need to breakout to the back panel
[20:17:39] <PCW> 'nite Andy
[20:17:58] <somenewguy> OH, I misread, that MESA board is only 90 bucks. that makes my future a lot easier
[20:18:31] <somenewguy> But I will stick to the rig I have now, get dual boot up and running (got some windows license I don't want to lose) and save my money to spend on the cooling rig
[20:18:53] <somenewguy> I have an old parts washer that has a date with a saw and torch to become a tank for a flood cooling rig
[20:19:36] <somenewguy> just need to settle on which corner of the shop is getting covered in a fine mist of coolant and glass (setting up a galss bead cabinet as well)
[20:19:51] <somenewguy> and don't worry, the mill will live under a tarp to protect it from abrasivs
[20:33:53] <PCW> bbl
[20:34:35] <jp_mill_> PCW: it was just a polarity issue followed both dive and board manuals but none the less i had to invert
[20:38:03] <jp_mill_> guess i could of inverted my input scale or something
[20:56:02] <roycroft> i have my media blasting cabinet in my welding shop
[20:56:20] <roycroft> i do all sanding/grinding/etc. out there, keeping it away from my machine shop
[20:56:53] <roycroft> but i have to share the machine shop with woodworking tools, so there's a dust issue
[20:57:00] <roycroft> i keep everything covered, but it's still suboptimal
[20:57:25] <uw> yea agreed woodworking is worthless
[20:57:42] <uw> i graduated to metal a long time ago, never looked back
[21:00:42] <Chemeleon> worthless?
[21:01:44] <roycroft> it's not at all worthless
[21:02:05] <roycroft> but wood dust does not get along well with metalworking machinery
[21:02:50] <roycroft> and working with metal is definately not a "graduation" from woodworking
[21:03:00] <Chemeleon> yea, sadly I came to the conclusion that mixing sparks with my sawdust would be a bad idea
[21:03:01] <roycroft> that's a very bias that's not at all contructive
[21:03:09] <roycroft> constructive
[21:03:11] <Chemeleon> of course, I dont have the room for more giant machinery anyway...
[21:03:32] <roycroft> i don't either, which is why i have to share space
[21:03:49] <Chemeleon> next shop will, but who knows when that'll actually happen
[21:04:13] <roycroft> i'm getting to be of an age where the dream of the ultimate shop may end up being just that in the end
[21:04:23] <roycroft> i've not given up on the dream yet
[21:04:24] <uw> very bias? so wood products are known to last longer than metal ones?
[21:04:44] <uw> i guess it's just my opinion
[21:04:46] <roh> *sigh* *wait*
[21:04:46] <Chemeleon> wood doesnt rust ;)
[21:04:53] <roycroft> but as the days pass it's less and less likely
[21:04:58] * roh wants a toolchanger. even a manual one would do.
[21:05:13] <roycroft> you mean an apprentice? :)
[21:05:15] <Chemeleon> I've run the numbers and know exactly what I need to make it happen, but it'll require one of my projects to significantly improve sales
[21:05:33] <roycroft> the shop building itself is not the issue
[21:05:39] <roycroft> i don't have enough room on my property
[21:05:40] <Chemeleon> and even once I've got the 300k on hand I'll need, it'd still take at least 6 months from start to move in
[21:05:57] <Chemeleon> same, my current shop is as big as my town would allow (900sqft)
[21:06:01] <roycroft> i would dearly like to sell and buy some acreage
[21:06:01] <somenewguy> I am a youger dude with no space
[21:06:08] <roh> roycroft: hrr.. those get paid over here
[21:06:08] <somenewguy> so I am making do, and my engine stuff takes up most of the space
[21:06:11] <Chemeleon> next move, I'm aiming for 100 acres, and an 8k sqft steel building, divided into half shop, half house
[21:06:24] <roycroft> that's the problem
[21:06:46] <Chemeleon> I could *maybe* have done metalworking too if I'd just stuck to small machines for the woodworking
[21:06:47] <roycroft> 10 acres would make me happy
[21:06:50] <Chemeleon> but the big stuff is just too neat...
[21:07:01] <roh> roycroft: also it would need another z touch-off needed after changing the tools... so i am cycling workpieces now, doing the same steps all the time, waiting for the machine to complete its 5-10minute long step
[21:07:17] <Chemeleon> I can find plenty of land in this region for 1-2k/acre, so 100 acres seems like the sweet spot between space and cost to me
[21:07:19] <roycroft> a 5000 ft^2 timber frame shop, a geodesic dome for a house, and a brewery in a treehouse
[21:07:23] <Chemeleon> and gives me room for a trebuchet or two :)
[21:07:25] <roycroft> that is my dream :)
[21:07:32] <somenewguy> good dream
[21:07:34] <Chemeleon> fancy dream :)
[21:07:43] <Chemeleon> not sure about the brewery in a treehouse though
[21:07:44] <roycroft> but by the time i can do that i may not be able to climb up into the treehouse any more
[21:07:47] <Chemeleon> sounds tiring to lug the casks out :)
[21:07:56] <roycroft> that's what lifts are for
[21:08:01] <somenewguy> I live in damn new england and need to stay close enoug hto the city to work, when I find more than an acre in my price ragne I get excited
[21:08:20] <Chemeleon> luckily I work for myself, as long as I have internet and power, I'm good to go
[21:08:27] <somenewguy> I'm working on that
[21:08:34] <somenewguy> half self employed, thats how I jsutify the tools
[21:08:37] <Chemeleon> only reason I'd stay in this general area is because most of my family lives in this state
[21:08:45] <somenewguy> same
[21:08:48] <somenewguy> all 200 of em
[21:08:50] <roycroft> i'm on the west coast
[21:08:59] <roycroft> i'm here because it's such a great place to be :)
[21:09:01] <Chemeleon> gotta love being able to write off the toys on your taxes huh somenewguy? :)
[21:09:08] <somenewguy> yeap!
[21:09:27] * somenewguy goes and gives his new lincoln 300 a little pat
[21:09:28] <Chemeleon> that was actually one of my reasons for starting to write cam software, ensures the irs cant fuss ;)
[21:09:35] <roycroft> i generally dislike the east coast, but i could be happy living in boston, if i had a money tree or two
[21:09:47] <somenewguy> I would reccomend 2
[21:09:51] <roycroft> at least
[21:10:09] <roycroft> it's an awesome city though
[21:10:16] <roycroft> as far as cities go
[21:10:21] <Chemeleon> steel building wouldnt be the prettiest "house", but its by far the most cost effective option I can come up with for large size
[21:10:32] <Chemeleon> and I figure building what essentially amounts to a house inside it should make it very well insulted
[21:10:37] <somenewguy> I keep looking at converted barsn
[21:10:39] <roycroft> aesthetics are really important to me
[21:10:44] <Chemeleon> and that'd still leave 4-5k for shop space
[21:10:48] <somenewguy> there is a pretty decent number out this way, but they are never near ANYTHING
[21:10:51] <uw> Chemeleon, will last longer i reckon too ;)
[21:10:51] <roycroft> i can't function well in a space where i'm not comfortable
[21:10:59] <Chemeleon> uw, yep, quite likely
[21:11:10] <Chemeleon> and would be weather tight very quickly, so I could camp out there while building the house
[21:11:27] <roycroft> at any rate, it's dinner time
[21:11:30] * roycroft ciaoders
[21:11:42] <somenewguy> I seriously thought about buying this mess of a barn to convert o a house/work space
[21:11:51] <somenewguy> I have a VW bus so I can always live out of that in the drivewayy til lits donw
[21:11:52] <somenewguy> done
[21:12:08] <uw> somenewguy, hey what year bus do you have?
[21:12:15] <somenewguy> the thing was HUGE, more sq feet than anyone would know what to do with
[21:12:23] <somenewguy> 73 and 77
[21:12:33] <Chemeleon> somenewguy, I'm a firm believer in that being impossible :)
[21:12:41] <Chemeleon> no matter how much space you have, eventually you'll fill it up
[21:12:52] <uw> very cool i had a 74 westfalia
[21:12:52] <Chemeleon> the only question is how long that'll take :)
[21:12:53] <somenewguy> the 77 has been cut up to feed the 73, but the 77 was my first car, got me thru college when I lived in it
[21:13:04] <Chemeleon> hippy ;)
[21:13:40] <somenewguy> them's fighting words
[21:14:02] <somenewguy> I am an engineer thankyouverymuch
[21:14:07] <Chemeleon> heh
[21:14:11] <somenewguy> I belive in reality and ppl suck so I will stick to my machines
[21:14:22] <Chemeleon> here here
[21:14:36] <Chemeleon> you know, I wish land listings included the important stuff
[21:14:44] <Chemeleon> what sort of internet is available in the area, whether 3ph power is possible, etc
[21:14:51] <roh> heh. you got it warm enough to survive a winter in a vw?
[21:14:54] <Chemeleon> I dont care that theres a lot of ducks on it dangnabbit
[21:14:56] <somenewguy> cable guage etc?
[21:15:07] <somenewguy> I'm a polar bear it turns out
[21:15:17] <Chemeleon> same
[21:15:29] <Chemeleon> though from my pov, I'm normal, everyone else are just major wimps when it comes to temperature ;)
[21:15:29] <somenewguy> 5 below was pretty miserable, but after a winter of that, you don't complain any more!
[21:15:45] <Chemeleon> f or c?
[21:15:53] <somenewguy> I didn't have any heat, but a pretty damn nice down blanket made a big difference
[21:15:55] <somenewguy> F
[21:16:01] <Chemeleon> yea, thats a little cool :)
[21:16:07] <somenewguy> tid bit nipply
[21:16:16] <somenewguy> although there were some lasting effects
[21:16:20] <Chemeleon> I dont even drop the "summer" clothes until its below 20f typically
[21:16:23] <somenewguy> I can no longer sleep without my arms and blanket over my head
[21:16:29] <Chemeleon> heh
[21:16:31] <uw> yea i wouldnt want that and i thought i was an ice bandit yike
[21:16:32] <uw> s
[21:16:38] <Chemeleon> I thought you were going to say lost some toes or some such :P
[21:16:44] <somenewguy> from trying to stay warm in the bus for 2 years, now even in the summer I NEED to have my arms over my head
[21:16:58] <somenewguy> sharing a bed w/ anyone, they take a while to get used to it
[21:17:12] <somenewguy> sucks cause I over heat in the summer, but I just don't feel comfortable otherwise
[21:17:21] <somenewguy> its wierd, but a fun story!
[21:17:38] <Chemeleon> in the winter, unless I'm expecting visitors I dont even heat the house beyond a few deg above freezing to keep water flowing
[21:17:53] <somenewguy> more money for toys!
[21:17:56] <Chemeleon> yup
[21:18:00] <Chemeleon> I tried heating it one month
[21:18:13] <Chemeleon> $500 bill for just the last 3 weeks of the month convinced me cold is fine
[21:18:36] <Chemeleon> I've put some more insulation in, and have a good sized wall heater in my office for when it gets annoyingly cold out
[21:18:54] <Chemeleon> but I see no point in spending a couple hundred a month to heat the whole house when I'm comfortable without it
[21:19:19] <Chemeleon> and thanks to the house design, AC isnt needed in the summer :)
[21:19:38] <Chemeleon> it can be pushing 100F outside, and inside it'll barely break 80
[21:20:30] <Thetawaves_> 500/month is high even for a alaska
[21:20:58] <Chemeleon> yea, thats what happens when you try to heat a mid sized century+ old house that had almost no insulation :)
[21:21:12] <somenewguy> I can back up that claim
[21:21:17] <Chemeleon> attic is now insulated beyond whats recommended around here
[21:21:23] <Chemeleon> but theres still a ton of very large old windows
[21:21:30] <Chemeleon> not even remotely cost effective to replace them
[21:21:43] <somenewguy> I live in an old colonial now, even with added insulation we've put in over the years, we are down from 600 to 200, but still, those are real numbers
[21:21:49] <Chemeleon> and impossible to insulate the walls short of building false walls over top the current
[21:21:56] <Thetawaves_> it is cost effective at 500/month
[21:22:08] <somenewguy> if you heat, replacing the windows makes a huge difference, but clearly you have solved your expesne problem with a different approach
[21:22:15] <Thetawaves_> (also, get the cellophane stuff that goes over your windows)
[21:22:23] <Chemeleon> I have 27 windows, with an average size of 3'x6'
[21:22:40] <Chemeleon> even if I just did storm windows on the outside, it would cost a big chunk of cash
[21:23:26] <Chemeleon> I can run the infrared gas heater in the office full blast all month long and stay in the double digit cost range
[21:23:34] <Chemeleon> and most of my time is spent in the office or workshop anyway
[21:23:49] <Chemeleon> and at night, a down comfortor or two and a pair of siberian huskies take care of heat there :)
[21:51:55] <CaptHindsight> http://hackaday.com/2013/09/19/beaglebone-black-does-cnc-with-ramps/ I would have gone for one or two more stacks of boards just for fun

[22:08:51] <Valen> what is the latency like on that thingie?
[22:10:47] <CaptHindsight> Valen: I think I heard around 30-35uS
