[00:01:39] <r00t4rd3d> <MattyMatt> ah 5am. gn
[00:05:17] <r00t4rd3d> http://www.thingiverse.com/thing:17175
[00:06:52] <r00t4rd3d> that one in the video uses a Arduino Mega as a controller
[00:07:07] <r00t4rd3d> http://reprap.org/wiki/Rostock#Calibration
[01:55:02] <Loetmichel> mornin'
[02:03:25] <theos> o/
[02:19:37] <Jymmm> hola
[03:27:17] <DJ9DJ> moin
[05:33:41] <mrsun> hmm, anyone heard of someone that has built his own hexapod cnc milling machine? :)
[05:35:45] <archivist> there is one on yourtube http://www.youtube.com/watch?v=G_UmhUjZhNo
[05:36:38] <mrsun> oh a beefy one =)
[05:37:23] <mrsun> expensive build i recon
[05:37:29] <mrsun> tho, no linear guides needed =)
[05:41:47] <Valen> we are building a new router currently
[05:41:59] <Valen> or thinking about how to best go about said thing
[05:42:10] <Valen> think a hexapod is a good way of doing it?
[05:43:23] <Valen> how are they generally for accuracy
[05:44:55] <archivist> I imagine any play is magnified
[05:45:15] <archivist> so I wont be making one
[05:47:26] <Valen> 's what i figured
[05:47:30] <Valen> neat, but sloppy
[05:50:42] <jthornton> I'd hate to program that
[05:53:34] <Valen> thats what the kins module is for
[05:53:51] <Valen> you just write a G1 X50 and it makes all the motors move to do that for you
[05:53:59] <Valen> the homing sequence could be interesting though lol
[05:57:18] <mrsun> hexapods from what i understand is extremly rigid, but like archivist said .. play would be a problem
[05:57:23] <mrsun> i would like hexapods to be able to get away with say milling or grinding stone etc without a chance of grit getting on the ways etc =)
[05:57:25] <mrsun> as there is no ways
[05:57:39] <mrsun> just cover all "axles" with bellows and voila
[05:58:00] <archivist> with the right covers normal ways can be used for stone
[05:58:56] <mrsun> true, but you do not get the 45 degree tilting for free like you do with hexapods =9
[05:59:35] <archivist> stone saw/mill http://www.collection.archivist.info/archive/DJCPD/PD/2012/2012_08_10_York_stonemasons/IMG_1307.JPG
[06:01:42] <mrsun> yeah thats also a way to do it, get the guideways off the ground level =)
[06:02:00] <archivist> you see the upper right saw cuts http://www.collection.archivist.info/archive/DJCPD/PD/2012/2012_08_10_York_stonemasons/IMG_1306.JPG
[06:23:17] <MattyMatt> awallin, no it's arduino controlled
[06:26:01] <MattyMatt> that semi-delta bot with vrtical guides will be less sloppy than a true delta with elbows
[06:27:31] <MattyMatt> you could do one of those with 6 slides and get hexapod kins
[06:28:23] <MattyMatt> or put the pan & tilt on the head
[06:36:24] <MattyMatt> archivist, what's going on in that pic? has the cnc removed excess material is preparation for the lion to be carved by hand?
[06:37:16] <archivist> yes they have removed a chunk with the saw
[06:38:25] <archivist> it was Yorkminster stomemasons open day aug 10th
[06:38:52] <MattyMatt> I guess they're not ready to let a machine do the fine carving yet
[06:39:26] <archivist> they do have dremel type tools for getting a qty out
[06:40:00] <MattyMatt> I mean automatically from 3d scans of the original
[06:41:45] <MattyMatt> with CNC'ed moulds, all modern concrete buildings could look like cathedrals for not much extra cost
[06:44:05] <MattyMatt> I've got some public housing drawings somewhere with gothic arches on the walkways etc.
[06:46:12] <MattyMatt> give the kids on the estates some gargoyles to throw stones at, I say
[06:49:38] <MattyMatt> churches get all the best stonemasons
[06:50:22] <MattyMatt> but the devil has the best tunes :D
[06:52:20] <archivist> the gargoyles puke on the kids http://www.collection.archivist.info/archive/DJCPD/PD/2012/2012_08_10_York_stonemasons/IMG_1298.JPG
[06:53:21] <MattyMatt> yep vital feature
[06:53:53] <archivist> the set depict illnesses around that tower
[06:54:09] <MattyMatt> my walkways all had planters fed by rainwater, so there's always some soil for the kids to puke/piss/bleed into on their way home at night
[06:59:11] <MattyMatt> and flat walls atttract grafitti, so every wall would have an interesting texture
[07:00:16] <MattyMatt> I should rationalise my drawings into a single tower block and get it all in the computer. it should only take me as long as it takes to qualify as an architect
[07:24:01] <r00t4rd3d> so 5 minutes
[07:24:44] <r00t4rd3d> most architects are fucking retards that dont know real world shit and can only draw shit to scale.
[07:33:39] <r00t4rd3d> 10 years as a construction laborer should be a architect requirement.
[07:35:50] <archivist> that should be widened to no designer of any sort to design without direct manufacturing experience
[07:35:56] <sebastian1> hello
[07:36:36] <sebastian1> is there any documentation or tutorial for writing something like image-to-gcode?
[07:37:56] <r00t4rd3d> im sure there is some linux version where you could look at the source.
[07:39:02] <sebastian1> ok thx, i think i got it
[07:39:24] <sebastian1> i think it's possible to use any console application
[07:39:40] <r00t4rd3d> why you wanna do this anyway with lots of other programs already out there
[07:40:35] <sebastian1> i need a preprocessor for some gcode files
[07:41:27] <r00t4rd3d> i got some
[07:41:49] <r00t4rd3d> oh wait those are post processors
[07:42:01] <sebastian1> ohhh ok
[07:42:21] <sebastian1> no i want to edit the gcode file before loading into EMC
[07:43:56] <r00t4rd3d> what is it you are trying to do? Why the edit or what ever?
[07:47:11] <sebastian1> i want to add gcode for a tangential knife (don't know if it's called that way in english)
[07:48:25] <jdh> in english, it is tangential knife.
[07:48:31] <r00t4rd3d> lol
[07:48:36] <r00t4rd3d> cant you just edit the tool table?
[07:48:48] <jdh> it's a special tool
[07:48:51] <r00t4rd3d> add your tool then set it in the gcode
[07:49:15] <jdh> you need to control the knife angle
[07:49:23] <sebastian1> jdh is rigt
[07:49:50] <sebastian1> i think i'll write a little java program that calculates the angles
[07:50:20] <jdh> you just move the knife as an A axis?
[07:50:58] <r00t4rd3d> you have a link for this tangential knife?
[07:51:10] <jdh> I could google it for you if you would like.
[07:51:38] <sebastian1> jdh yes as an A axis
[07:53:23] <jdh> looks like there is an inkscape plugin that exports gcode for tangential knives.
[07:56:39] <sebastian1> yes i've noticed that, but writing a preprocessor for EMC would be the easiest and most elegant way
[07:58:20] <sebastian1> i've also tried gantrykins from the linuxcnc forum
[07:58:21] <sebastian1> http://www.linuxcnc.org/index.php/english/component/kunena/?func=view&catid=10&id=4163
[07:58:48] <jdh> not tangentkins?
[07:58:57] <sebastian1> sry tangentkins
[07:59:21] <sebastian1> :-[
[08:05:30] <sebastian1> thats the right thread
[08:05:31] <sebastian1> http://www.linuxcnc.org/index.php/english/component/kunena/?func=view&catid=10&id=13083&start=6
[08:14:01] <r00t4rd3d> anyone wanna make a chair/ladder like this ? http://i.imgur.com/wHbNn.jpg
[08:15:09] <r00t4rd3d> http://i.imgur.com/d3p0z.jpg
[08:15:42] <mrsun> hmm i wonder what effects you would need to cut like 2mm of rubber
[08:15:44] <mrsun> laser
[08:16:07] <r00t4rd3d> vbit would probably work too
[08:16:22] <jdh> tangential knife
[08:16:26] <r00t4rd3d> lol
[08:16:36] <mrsun> ahh true
[08:17:27] <mrsun> but laser would be neater :P
[08:22:09] <mrsun> http://www.cnc-plus.de/product_info.php?info=p1363_schleppmesserhalter-fuer-schleppmesser-.html something like that then ? :)
[08:25:35] <jdh> ahh... the old Schleppmesserhalter
[08:25:57] <jdh> that's just a free-spinning drag knife?
[08:50:00] <r00t4rd3d> http://i.imgur.com/mN3AH.gif
[08:55:36] <r00t4rd3d> http://www.liveleak.com/view?i=d56_1345637909
[08:55:53] <r00t4rd3d> ride one of those around the world
[09:00:29] <Jymmm> mrsun: Laser used to make rubber stamps all the time, but STINKS !
[09:03:34] <mrsun> Jymmm, ahh
[09:03:45] <mrsun> jdh, i guess? :)
[09:05:35] <Jymmm> mrsun: http://www.gccworld.com/laserproi_en/engr_showcase_detail.php?ID=English_040916195346
[09:07:01] <mrsun> http://www.laserables.net/uk/
[09:07:02] <mrsun> :P
[09:07:50] <Jymmm> lies, smells way less, but still smells
[09:08:17] <Jymmm> It's not real rubber like on tires
[09:08:41] <Jymmm> just fyi
[09:08:53] <mrsun> as long as it resists the blast of sand blasting im happy :P
[09:09:23] <Jymmm> it's pretty soft and squishy
[09:09:27] <mrsun> atm im just trying things out, my ex mom called me and asked if i could engrave in stone =)
[09:09:39] <mrsun> so found that they sand blast stone
[09:09:43] <mrsun> with stencils
[09:09:45] <Jymmm> Oh, the laser can do that
[09:09:50] <Jymmm> no stencils
[09:09:57] <mrsun> ahh yeah ..but i have no laser :(
[09:10:02] <mrsun> was thinking of building one :P
[09:10:08] <mrsun> but if its to high effect its to high cost =)
[09:10:26] <jdh> ex mom?
[09:10:32] <Jymmm> there are sand blasting mediums for that
[09:10:47] <mrsun> my exes mom :P
[09:10:50] <mrsun> or whatever :P
[09:11:04] <mrsun> tried with al oxide now, didnt eat stone to well
[09:11:32] <Jymmm> soda?
[09:11:35] <Jymmm> nm
[09:13:15] <mrsun> gah
[09:13:24] <mrsun> what was the last thing that came trought from me ?
[09:15:07] <Jymmm> mrsun: my teddy bear in granite http://i54.tinypic.com/k2mo7n.jpg
[09:15:21] <mrsun> nice =)
[09:15:26] <mrsun> laser etched i guess? :)
[09:15:30] <Jymmm> yeah
[09:16:14] <mrsun> know what media to use for sandblasting stone? :)
[09:16:58] <Jymmm> OH, I remember.... vinyl
[09:17:20] <Jymmm> like they use for cars, windows, etc
[09:17:29] <mrsun> huh ? :P
[09:18:10] <Jymmm> http://doityourselflettering.com/
[09:19:07] <Jymmm> get a local shop tocut what you want, apply it to the stone and blast away
[09:20:16] <Jymmm> mrsun: ^^^^^^^^^
[09:20:41] <mrsun> well do not have much of local shops around here ;P
[09:21:14] <Jymmm> no sign shops?
[09:21:59] <mrsun> hmm, there is one but dunno if they cut rubber =)
[09:22:15] <Jymmm> how many do you have to make?
[09:22:31] <mrsun> Jymmm, dont know, if they sell well for them there can be quite alot :P
[09:22:44] <mrsun> they want someone that they dont have to order 100 - 200 pieces or so minimum order from
[09:23:22] <Jymmm> well, add the sot of vinyl lettering per onesy twosy
[09:23:27] <Jymmm> cost
[09:23:46] <r00t4rd3d> wtf
[09:24:46] <Jymmm> mrsun: The ppl I know that do that larger qty use metal stencils for blasting
[09:25:04] <Jymmm> but for one offs, vinyl lettering
[09:25:43] <mrsun> does venyl resist enough for sand blasting ?
[09:25:50] <r00t4rd3d> local headstone place uses 1/8 rubber sheets
[09:26:47] <Jymmm> http://www.etchworld.com/ecom-catshow/Sandblasting+Vinyl.html
[09:27:44] <Jymmm> http://www.nationalstencil.com/rubber_sand_blast_stencil.html
[09:54:32] <Jymmm> cnc punch http://www.youtube.com/watch?v=IAHU0a03OPM
[09:57:56] <syyl> pretty slow cnc punch ;)
[09:58:01] <Jymmm> I'll take two please... http://www.youtube.com/watch?v=EU3SKaBFHIk&NR=1&feature=endscreen
[10:01:47] <Jymmm> nm, it uses windows.
[10:02:01] <Jymmm> ;)
[10:36:14] <Loetmichel> uhhhh
[10:37:10] <Loetmichel> teh punch si REALLY slow... ne of my supplyers has a big Trumopf CNC punch... full size sheets, up to 6mm steel
[10:37:21] <Loetmichel> that punches about 10 times that speed
[11:02:32] <Jymmm> whats usually cheaper, 302 or 304?
[11:02:45] <Jymmm> is sheet stock
[11:23:25] <Tom_itx> Jymmm i bet your local vendor could answer that
[11:24:26] <Jymmm> Not vender, but mfg. and they have a tendancy to just qutoe what they are told and not what you describe
[11:27:15] <Tom_itx> 302 is considered a specialty alloy in sheet where 304 is common
[11:27:25] <Tom_itx> http://www.onlinemetals.com/merchant.cfm?id=836&step=2&top_cat=1
[11:28:05] <Jymmm> they dont even list 316 either, hmmm
[11:28:49] <Jymmm> I WANT 316, just dont know if I can AFFORD 316 =)
[11:29:06] <Tom_itx> if you wonder... you can't
[11:29:24] <Jymmm> ah found 316 http://www.onlinemetals.com/merchant.cfm?id=232&step=2&top_cat=1
[11:29:41] <taiden> what is dmsg and how do I check it?
[11:29:54] <Tom_itx> from a terminal type 'dmesg'
[11:29:57] <Tom_itx> then read it
[11:30:37] <Tom_itx> 316 must be more common than 302 too
[11:30:58] <t12> speaking of strange stainless
[11:31:13] <taiden> incoming text bomb
[11:31:14] <t12> anyone happen to know what this weird stainless is that seems to be used on 50-60's european scientific equipment
[11:31:37] <t12> seems to get SLIGHT surface corrosion, very dull grey
[11:31:50] <taiden> http://pastebin.com/RBFRK6i0
[11:32:00] <Jymmm> Tom_itx: how so? I got a quote for 302 and 316, the 316 was about 5% higher
[11:32:08] <taiden> i stress tested my computer overnight with no jumps
[11:32:29] <taiden> today im cutting a part and computer skips enough steps to throw my toolbit 2 inches deep into my fixture
[11:32:43] <Tom_itx> Jymmm did you price 302?
[11:32:52] <Tom_itx> err 304
[11:33:05] <Jymmm> no just 302 and 316
[11:33:10] <Tom_itx> heck if i know
[11:33:20] <Jymmm> =)
[11:33:31] <t12> taiden: any messages immediately before that?
[11:33:32] <Tom_itx> i figured it would be higher since it was listed under 'specialty'
[11:33:40] <t12> 1/10th second hang is pretty big
[11:34:23] <taiden> i will pastebin the whole log
[11:34:32] <Jymmm> Tom_itx: Yeah nfc. I'll call the mill and find out what a master roll costs for each grade.
[11:35:03] <taiden> http://pastebin.com/Daf1h0hS
[11:35:09] <taiden> i dont know what to do
[11:35:20] <taiden> i have about 6 hours on this computer of cnc time
[11:35:22] <taiden> and this has never happened
[11:35:36] <taiden> i was not doing anything out of the ordinary
[11:35:44] <taiden> terminal and linuxcnc open and that's it
[11:35:53] <taiden> with one instance of vim
[11:37:37] <t12> large job file?
[11:37:41] <JT-Shop> did you run the latency test for an extended period of time?
[11:37:50] <taiden> same as the other hours i was running
[11:37:54] <t12> (what kind of laptop)
[11:38:05] <taiden> i did a 18 hour test with glxgears, do loop, and ping
[11:38:19] <taiden> and set up my latency in stepconf about 25% higher than my findings with that
[11:38:40] <awallin> that what was someone else was reporting on the list also? that latency-test runs fine but linuxcnc complains about realtime-errors?
[11:38:52] <mrsun> yeey finaly the first part of my wood workshop is getting into the final stages =) started to put in a door today! =)
[11:39:08] <taiden> fwiw i am running this on an old p4 desktop
[11:39:12] <mrsun> ceiling almost done, walls done, flood done =)
[11:39:15] <mrsun> floor
[11:39:18] <taiden> but bios doesn't give the option to disable hyperthreading
[11:40:00] <taiden> since i logged into irc my times are 8.7k / 10.5k
[11:41:37] <mrsun> isnt that a matter of how the delays in stepconf is setup ?
[11:41:40] <mrsun> if it complains or not? :)
[11:42:01] <taiden> i believe it matters if the delay exceeds your settings
[11:42:10] <taiden> then it gives that dialog
[11:42:23] <mrsun> yeah thats what i ment =)
[11:42:23] <taiden> i came up with my settings by doing to aforementioned 18 hour stress test
[11:42:36] <taiden> i am not sure how else to come up with the numbers to use
[11:42:59] <taiden> i believe something strange is happening that is causing a single spike of latency and apparently my 18 hour test didn't capture that
[11:43:24] <taiden> so short of crossing my fingers and hoping i don't wreck parts again i'm not sure what to do at this point
[11:43:33] <awallin> latency-test and linuxcnc don't necessarily measure the same thing. I think that was the conclusion from the discussion on the list.
[11:43:48] <taiden> alright
[11:43:59] <taiden> hm
[11:44:07] <taiden> i hate to ask this question, is it time for Mach?
[11:44:21] <awallin> but the usual tweaks are bios-settings, possibly "isolcpus" kernel-argument, etc.
[11:45:00] <taiden> yeah but
[11:45:07] <taiden> i have no way to measure these spikes that i know of
[11:45:19] <taiden> since my latency test doesn't record anything about 10k 15k
[11:45:50] <taiden> are there any controllers that interface with emc2 that dont rely on the cpu for stepping timing?
[11:46:31] <awallin> mesa-cards are popular. but you still need reasonable latency on the pc
[11:47:26] <awallin> there is motion-controller.time and motion-controller.tmax which might be monitored
[11:47:37] <awallin> or motion.servo.overruns or motion.servo.last-period
[11:48:30] <awallin> but if you monitor last-period you will just see a big number at the same time as linuxcnc shuts down because of that number. I think..
[11:49:41] <t12> 100ms seems like it'd be a
[11:49:46] <t12> maybe a driver hanging
[11:49:53] <t12> hard drive hanging in ISR?
[11:50:00] <t12> that is an old maxtor
[11:50:23] <awallin> I got these 155ms delays on one motherboard. repeated every 10 minutes. never figured that out, just changed motherboards.
[11:50:36] <joe9> taiden: check out smi
[11:50:40] <t12> i've seen machines where hard drive io would cause system time lose
[11:50:43] <t12> loss
[11:50:46] <joe9> taiden: what you are talking about seems smi related
[11:51:00] <joe9> taiden: hold on, I take that back
[11:51:10] <joe9> taiden, the 18 hr test should have captured that.
[11:51:46] <JT-Shop> mesa cards like the 5i20 only use the slow thread
[11:52:01] <awallin> but 100ms is a killer even with a mesa card...
[11:52:36] <JT-Shop> [ 2912.484753] This time, there were 226010134 which is so anomalously
[11:52:37] <JT-Shop> [ 2912.484755] large that it probably signifies a problem with your
[11:52:37] <JT-Shop> [ 2912.484758] realtime configuration. For the rest of this run of
[11:52:37] <JT-Shop> [ 2912.484760] EMC, this message will be suppressed.
[11:53:26] <archivist> taiden, did you abuse the graphics/video while the latency test was running
[11:57:26] <t12> smartctl -a /dev/sda ?
[12:03:21] <Jymmm> Alright, which one of you did this??? http://i49.tinypic.com/5lny9x.jpg
[12:04:40] <Jymmm> kinda looks like Swapsourri in the background
[12:10:33] <Tom_itx> that's Jymmm's campin style...
[12:10:44] <IchGuckLive> hi all B)
[12:10:55] <Jymmm> Nah, too short ;)
[12:11:19] <Jymmm> and no 60" big screen
[12:18:25] <joe9> i have a weird issue. want to check what could be wrong. I bought a taig mill a few months ago. Today, when doing the z touch-off with a round dowel I notice the below behaviour
[12:19:27] <joe9> dowel passes under at Z-4.945 -> Z-4.946 (passes) -> Z--4.947 (does not pass) -> Z-4.946(does not pass) -> Z-4.945(passes)
[12:19:39] <joe9> I repeated the above more than a few times
[12:20:07] <joe9> and do not understand why it would NOT pass with -4.946 on the way up, but the dowel passes on the movement down.
[12:20:16] <joe9> Is something off on my machine.
[12:20:26] <joe9> ?
[12:20:30] <joe9> any thoughts, please?
[12:20:50] <joe9> I did not use the machine much but for a few hours, in total.
[12:20:58] <Jymmm> backlash?
[12:21:11] <Jymmm> do you have a dial indicator?
[12:21:15] <joe9> 0.001inch backlash seems to be high, don't you think?
[12:21:16] <JT-Shop> backlash
[12:21:24] <joe9> Jymmm: yes, I have a dial indicator.
[12:21:33] <JT-Shop> acme screws?
[12:21:43] <joe9> is that acceptable backlash? on a few month old machine?
[12:21:45] <Jymmm> joe9: Toss it on your Z and run some cycles
[12:21:59] <JT-Shop> acme screws?
[12:22:23] <joe9> JT-Shop: i did not change anything. they are the factory screws.
[12:22:41] <Jymmm> joe9: Are the factory screws acme or ballnut?
[12:22:49] <joe9> btw, before I start worrying about this, Should this be a worrisome issue?
[12:22:49] <JT-Shop> are they acme or ball screws?
[12:23:05] <joe9> JT-Shop: i think the factory screws are acme screws.
[12:23:12] <IchGuckLive> joe9: if you can live with it its not an issue
[12:23:15] <Jymmm> joe9: pic?
[12:23:16] <joe9> Jymmm: ^^
[12:23:35] <JT-Shop> check to see if you have a 1/2 nut and if it is loose due to you just getting the screw and nut broken in
[12:24:29] <Jymmm> JT-Shop: 1/2"-20 leadscrews on X,Y,& Z
[12:24:36] <Jymmm> http://www.taigtools.com/mmill.html
[12:26:08] <Jymmm> parts list at bottom. and with a $19 nut, I doubt that's ballnut =)
[12:29:04] <joe9> Jymmm: ok, thanks.
[12:29:17] <joe9> JT-Shop: will check if there is any adjustment around.
[12:29:55] <IchGuckLive> dont tight to hard jo
[12:30:57] <joe9> i have a starret edge finder. Two times, I think I went too close to the edge and the bottom edge contacting portion unscrewed itself.
[12:31:22] <joe9> I pulled out the spring and screwed the bottom portion back in.
[12:31:48] <joe9> It still seems to work. Not sure if you would still consider it a "good" edge finder?
[12:31:55] <joe9> or, would you recommend trashing it?
[12:32:28] <IchGuckLive> if it works for you its ok
[12:32:35] <joe9> i am not a machinist. I find that instead of relying on the noise of the edge finder, putting a finger at the edge finder joint is more reliable.
[12:33:08] <joe9> when the lower portion is out of alignment from the top portion and I can feel it with the finger, I know that I have reached the edge.
[12:33:14] <joe9> Is this a good practice?
[12:33:16] <JT-Shop> joe9: if it is repeatable it might be fine
[12:33:57] <joe9> yes, other than similar behaviour (Z-4.945 -> Z-4.946 (passes) -> Z--4.947 (does not pass) -> Z-4.946(does not pass) -> Z-4.945(passes)) on all axes, it is repeatable.
[12:34:02] <joe9> JT-Shop: ^^
[12:34:04] <IchGuckLive> repeatable is the goal
[12:34:09] <joe9> ok, thanks.
[12:34:20] <JT-Shop> when I use an edge finder max RPM is 1000, slowly move till the bottom jumps to the side and your done
[12:34:55] <IchGuckLive> 1000 ? 300-400
[12:35:12] <joe9> JT-Shop: mine is not jumping to the side. I can feel it with my finger but there is no jump.
[12:35:16] <JT-Shop> also check for loose thrust bearings if you have any
[12:35:26] <joe9> until I get too far, then it makes the noise.

[12:37:01] <IchGuckLive> http://www.youtube.com/watch?v=cA1IP379leA Hommade egefinder with a bearing
[12:37:34] <IchGuckLive> same precision lower cost more space
[12:51:41] <IchGuckLive> taid still here
[12:51:49] <IchGuckLive> do you got a kondenser line
[12:51:53] <IchGuckLive> all motors powerd by one device
[12:52:17] <taiden> EPP
[12:52:23] <IchGuckLive> taiden: can you give a short setup of the mashine motor type driver comunication part
[12:53:10] <IchGuckLive> -> Nema23 4,2A 24V ,Gecko, BOB12
[12:54:04] <IchGuckLive> if it worked for that long time its shure not the PC
[12:54:15] <taiden> it is because
[12:54:26] <taiden> linuxcnc gave me unexpected realtime delay error
[12:54:43] <IchGuckLive> at 17+ hr
[12:54:49] <taiden> only while running
[12:54:56] <taiden> p4 pc > mobo parallel port > geckco g540 > keling 381 oz in
[12:54:59] <IchGuckLive> is there a real mashine running that time
[12:55:03] <t12> taiden: dd if=/dev/zero of=/tmp/somefile.dat bs=8192 count=10000 will write 800 mb
[12:55:13] <t12> increase count to increase amount written
[12:55:22] <taiden> excellent thank you
[12:55:54] <IchGuckLive> taiden: Powersorce volt 48?
[12:56:01] <taiden> yes
[12:56:12] <taiden> this is awkward, latency test wont run anymore
[12:56:15] <t12> you can also run iostat -m 1
[12:56:19] <taiden> oh nvm emc2 was open
[12:57:54] <taiden> this may actually be a trivial fix
[12:57:54] <t12> the number should stay fairly stable
[12:57:54] <taiden> i think i may have screwed up somethign really simple previously
[12:57:54] <t12> run that while dd i think
[12:57:54] <t12> oh
[12:57:54] <t12> what?
[12:57:54] <IchGuckLive> taiden: whar do you mill more then 17+ hr
[12:57:55] <taiden> yeah
[12:57:55] <taiden> this is pretty ridiculous
[12:57:55] <taiden> so apparently i fed stepconf my servo thread numbers
[12:57:58] <taiden> instead of my basethread numbers
[12:58:11] <IchGuckLive> i made only a 9hr full speed test with last move to the dials
[12:58:18] <taiden> so i had it specced slightly below actual base thread jitter
[12:58:56] <IchGuckLive> at steppers it will stay at 100k
[13:00:10] <IchGuckLive> taiden: did you go with G5430 setup
[13:00:16] <taiden> yes
[13:00:17] <IchGuckLive> G540
[13:00:21] <taiden> nice controller
[13:00:44] <IchGuckLive> so change to other and go with double numbers
[13:01:00] <taiden> 17,000 jitter, 25000 min base period, 40000 Hz max step rate
[13:01:04] <taiden> seem to be what im going to use
[13:01:08] <IchGuckLive> thats still fast for every mashine
[13:01:30] <taiden> which ini file are these numbers contained within?
[13:01:31] <taiden> hal?
[13:01:50] <IchGuckLive> taiden: if you look into them you will see more
[13:02:02] <IchGuckLive> base 100k and servo 1mio
[13:02:32] <taiden> ?
[13:02:40] <IchGuckLive> look into the ini
[13:03:07] <taiden> is it CYCLE_TIME that i am changing?
[13:03:10] <taiden> to 0.017
[13:03:16] <IchGuckLive> no
[13:03:27] <IchGuckLive> cycle time is not to be changed
[13:03:39] <taiden> EMCMOT = motmod
[13:03:39] <taiden> COMM_TIMEOUT = 1.0
[13:03:40] <taiden> COMM_WAIT = 0.010
[13:03:40] <taiden> BASE_PERIOD = 30000
[13:03:40] <taiden> SERVO_PERIOD = 1000000
[13:03:50] <IchGuckLive> there is the issue
[13:04:03] <taiden> i'm not seeing it :(
[13:04:15] <IchGuckLive> get the Base to 50k
[13:04:35] <taiden> shouldn't it be 25,000?
[13:04:42] <IchGuckLive> it has always to be a devision of servo
[13:04:44] <taiden> based on what stepconf told me
[13:04:54] <IchGuckLive> double it
[13:05:15] <taiden> i thought that was min base period
[13:05:18] <taiden> ?
[13:05:31] <IchGuckLive> Base 50k and your done
[13:05:48] <taiden> ok so base 50k
[13:05:53] <taiden> what about comm_wait
[13:05:54] <IchGuckLive> also double the gecko 540 values and your good
[13:06:00] <taiden> huh?
[13:06:11] <taiden> that makes no sense
[13:06:19] <taiden> not to be rude but anyone else care to chime in here?
[13:06:30] <IchGuckLive> with 10k steps per second
[13:08:05] <taiden> alright
[13:08:08] <taiden> i changed that to 50k
[13:08:20] <taiden> now how can I change my jitter time?
[13:08:24] <IchGuckLive> the Gecko is on the min requirerments timing as it is the fastest but i woudt not go for that on 17+Hr working
[13:09:22] <IchGuckLive> taiden: what speed are you G0
[13:09:43] <IchGuckLive> at 400 stepsd per rev or more
[13:12:15] <IchGuckLive> 5min to go for me
[13:13:04] <JT-Shop> starrett just replied to my query about the 827A and said ~1000 RPM
[13:13:27] <IchGuckLive> ok
[13:13:56] <IchGuckLive> if your edge is wright its asa it is
[13:14:06] <IchGuckLive> O.O
[13:14:40] <IchGuckLive> i teatch my students at 400-600 with 500 as it is at the box marked
[13:15:49] <JT-Shop> the Starrett has no markings on the box or instructions on the inside that's why I just emailed them to ask
[13:16:13] <JT-Shop> maybe different manufactures have different reccommended speeds
[13:16:28] <IchGuckLive> i guess so
[13:18:02] <IchGuckLive> JT-Shop: the mitutoyo is have the price
[13:19:26] <JT-Shop> ?

[13:22:18] <IchGuckLive> ok im off BY

[14:01:45] <Loetmichel> r00t4rd3d: BAD boy!
[14:01:46] <Loetmichel> ;-)
[14:24:43] <JT-Shop> what's worse than spilling 1,000,000 turnip seeds on the floor?
[14:28:25] <tjb1> picking them up
[14:29:38] <archivist> vacuum cleaner with a new clean bag in it
[14:36:34] <jthornton> spilling 2,000,000
[14:37:23] <Tom_itx> who's counting anyway?
[14:38:17] <jthornton> not me
[14:40:58] <syyl> worse?
[14:41:11] <syyl> waiting untill the germ out the carpet
[15:34:22] <Nick001-Shop> With a Mesa 5i20 and 7i30 card, is there a way of seeing the index signal as its moving? I can see the encoder counts but not the index.
[16:13:52] <taiden> i'm trying to set up my .ini file to change the settings that are based on my jitter numbers
[16:14:05] <taiden> i'd use stepconf but i have backlash and stuff setup in my ini so i dont want it to overwrite all that
[16:14:28] <taiden> any guidance ?
[16:14:47] <taiden> .ini documentation doesn't mention jitter anywhere
[16:18:50] <JT-Shop> it's not an ini item unless you make it one
[16:23:22] <Tom_itx> JT-Shop will solidworks read a .scad file?
[16:23:27] <Tom_itx> some open source cad
[16:26:31] <r00t4rd3d> it should
[16:27:06] <Tom_itx> well of course it should
[16:27:27] <r00t4rd3d> download one and try
[16:27:51] <Tom_itx> i am
[16:27:56] <JT-Shop> dunno let me see if that is an opton
[16:28:16] <cpresser> i dont think so; open-scad is not really a cad-format. its more of a scripting language
[16:28:36] <Tom_itx> crap. will it export iges or something?
[16:29:27] <cpresser> "OpenSCAD is not an interactive modeller. Instead it is something like a 3D-compiler that reads in a script file that describes the object and renders the 3D model from this script file"
[16:29:38] <JT-Shop> 30 types of files but none with .scad
[16:32:29] <JT-Shop> recess time
[16:34:23] <taiden> so this is interesting
[16:34:48] <taiden> i am using the more advanced latency testing tool
[16:35:03] <taiden> /usr/real*/testsuite/kern/run
[16:35:10] <taiden> kern/latency/run ***
[16:35:19] <taiden> and it's finding 100ms spikes
[16:35:32] <taiden> that the linuxcnc latency test doesn't find for some reason
[16:35:37] <taiden> and they are seemingly completely random
[16:35:52] <taiden> i have only found two so far
[16:38:03] <r00t4rd3d> background process probably
[16:38:21] <Tom_itx> is 10.04 lucid?
[16:38:49] <taiden> hardy
[16:38:54] <taiden> 10.04 ran horribyl on this machine
[16:40:40] <DJ9DJ> 10.04 is lucid
[16:40:45] <Tom_itx> it's lucid
[16:40:47] <DJ9DJ> 8.04 is hardy
[16:40:55] <DJ9DJ> https://wiki.ubuntu.com/DevelopmentCodeNames
[16:40:59] <r00t4rd3d> "hardly"
[16:41:06] <taiden> sorry i thought you were asking me what i was running
[16:41:34] <taiden> r00t4rd3d: any tips on trying to track down which background process it is?
[16:42:05] <DJ9DJ> gn8
[16:42:26] <taiden> brb i'm going to restart and try to catch it, it seems that it happens right after startup
[17:18:57] <taiden> this is a nightmare
[17:19:10] <taiden> now anytime i try to jog i get following errors
[17:19:27] <taiden> i just want something that works
[17:21:17] <taiden> alright i need guidance
[17:21:27] <taiden> in ini file i had BASE_PERIOD at 30,000
[17:21:38] <taiden> IchGubLieb or whatever his name is said to change it to 50,000
[17:21:45] <taiden> after doing that i got following errors
[17:21:52] <taiden> i just set it to 25,000 and it runs fine
[17:22:00] <taiden> so i have no idea what's going on
[17:22:06] <taiden> docs seem to show it set at 50000
[17:24:01] <taiden> stepconf creates a file that is BASE_PERIOD 100,000
[17:32:09] <r00t4rd3d> <taiden> i just want something that works
[17:32:16] <r00t4rd3d> Intel Atom D525
[17:34:19] <taiden> what are the guidelines for setting BASE_PERIOD?
[18:18:05] <joe9> i have to make a notch in a pcb to fit this: http://www.digikey.com/product-detail/en/UB-MC5BR3-M404-4S-TB%20NMP/455-2567-1-ND/2538132?cur=USD
[18:18:31] <joe9> any suggestions on how I can do that? I do not want to pocket this as it might too hard on the bits.
[18:18:43] <joe9> but, not sure if that is actually not such a bad idea.
[18:18:49] <joe9> anyone with experience, please?
[18:18:57] <Tom_itx> ok cool. it can export stl and solidworks will import that
[18:19:50] <joe9> i was thinking of a nibbler but it might be a bit too hard.
[18:20:03] <joe9> could also use a file, but, probably not a good idea given the FR4 dust.
[18:41:02] <taiden> alright it happened again
[18:41:09] <taiden> at the exact same time as last time
[18:41:19] <taiden> RTAPI: ERROR unexpected realtime delay
[18:41:37] <taiden> threw my tooling off abut1 inch in the y
[18:41:49] <taiden> this just started happening overnight,
[18:45:16] <joe9> taiden: have you thought about using a ram linux image, ramdisk, if you suspect that it is the hard disk?
[18:47:54] <r00t4rd3d> did you update anything?
[18:48:03] <taiden> didn't touch anything
[18:48:07] <taiden> computer sat for about four days
[18:48:08] <taiden> started it up
[18:48:17] <taiden> now it does this
[18:48:23] <taiden> also
[18:48:38] <taiden> i havne't tried a ram linux image, but i did test latency while creating large blank files
[18:48:42] <taiden> and it had zero effect on latency
[18:49:10] <taiden> i can purchase an atom
[18:49:18] <taiden> but the bigger issue is time
[18:49:24] <r00t4rd3d> run the livecd and see what happens with that
[18:49:44] <r00t4rd3d> or try a fresh install of everything
[18:49:56] <taiden> i'm wondering if mach3 is better suited to small production environment?
[18:50:28] <r00t4rd3d> never tried it
[18:52:02] <taiden> it just pinkles my wrenis
[18:52:08] <taiden> that this setup was working flawlessly
[18:52:10] <taiden> until today
[18:52:22] <taiden> but i suppose complaining wont get me anywhere
[18:52:51] <taiden> r00t4rd3d: is there anything else you can think of? what is the simplest thing it could be?
[18:52:52] <r00t4rd3d> reinstall it all and see
[18:52:56] <taiden> reinstall
[18:53:07] <taiden> alright
[18:53:15] <r00t4rd3d> you got nothing to lose
[18:53:17] <taiden> i will reinstall
[18:53:28] <taiden> and i will rerun stepconf from fresh
[18:53:39] <taiden> and i will do my minor tweaks after
[18:53:46] <r00t4rd3d> just seems od 4 days ago it was okay and now its not
[18:53:51] <taiden> you got that right
[18:53:56] <taiden> my old setup would crash all the time
[18:54:09] <r00t4rd3d> makes me think hardware is going south
[18:54:13] <taiden> this one would hum along for days on end without any problems, 10k/15k solid on latency no matter how long i ran it
[18:54:21] <taiden> or how stressed it was
[18:54:33] <r00t4rd3d> all your heatsinks and fans clean?
[18:54:42] <taiden> actually
[18:54:46] <taiden> that's a good point because
[18:54:58] <taiden> i haven't cleaned it since i first put it up for cnc use
[18:55:02] <r00t4rd3d> lol
[18:55:13] <taiden> good thought i'll check that
[18:55:18] <taiden> in the mean time im going to order an atom box
[18:55:20] <r00t4rd3d> ive seen heat do some weird shit
[18:55:36] <taiden> do we know for certain that the d525 is the best of the bunch?
[18:55:41] <taiden> for realtime kernals
[18:55:44] <r00t4rd3d> i got a intel atom d525 and lots of others around here do too, they just work
[18:57:02] <r00t4rd3d> http://www.ebay.com/itm/Intel-D525MW-Mini-ITX-Motherboard-w-Atom-525-CPU-/200542103383?pt=Motherboards&hash=item2eb13da757
[18:57:08] <r00t4rd3d> i bought mine from him
[18:58:16] <r00t4rd3d> then this for memory:
[18:58:17] <r00t4rd3d> http://www.ebay.com/itm/RAMAXEL-4GB-DDR3-2x2GB-PC3-10600S-1333MHz-Laptop-Memory-Mac-Thinkpad-HP-Dell-RAM-/390449877210?pt=US_Memory_RAM_&hash=item5ae8a050da
[18:58:23] <r00t4rd3d> 15 bucks fills it
[19:01:19] <taiden> what are you using for storage again?
[19:01:30] <r00t4rd3d> sata hd
[19:01:39] <r00t4rd3d> http://www.ebay.com/itm/Brand-NEW-APEX-MI-008-250W-Mini-ITX-Case-/200708342703?pt=US_Computer_Cases&hash=item2ebb2643af
[19:02:00] <r00t4rd3d> that is the case you might also want, then its ready to go
[19:02:28] <r00t4rd3d> minus harddrive or what ever
[19:03:02] <r00t4rd3d> do you have a mini itx case already?
[19:03:23] <taiden> nope
[19:03:28] <taiden> only atx stuff
[19:03:35] <taiden> i have a brand new 450w atx power supply haha
[19:03:48] <taiden> would be a shame to waste it
[19:03:54] <Tom_itx> case on newegg is like $39 with psu
[19:03:54] <r00t4rd3d> you can use it
[19:04:12] <r00t4rd3d> you will just need a case that accepts a standard power supply
[19:04:43] <r00t4rd3d> or a atx case that accepts a mini itx board, some do
[19:04:43] <Tom_itx> umm...
[19:05:36] <r00t4rd3d> a 450w power supply is super overkill for a d525 but it will work

[19:06:12] <Tom_itx> same thing
[19:06:20] <r00t4rd3d> more $$
[19:06:29] <Tom_itx> 5 less
[19:06:31] <r00t4rd3d> w/ shipping
[19:06:43] <r00t4rd3d> 45.99+7.99
[19:06:51] <Tom_itx> i got mine for 39 with free shipping
[19:06:53] <Tom_itx> same case
[19:07:21] <r00t4rd3d> i think you have to spend over 100 to get free ship
[19:07:42] <Tom_itx> no it was advertised that way then
[19:07:46] <r00t4rd3d> oh
[19:07:58] <Tom_itx> i like the case
[19:08:02] <r00t4rd3d> i had one
[19:08:15] <r00t4rd3d> not a apex
[19:08:36] <r00t4rd3d> mine is more old vcr shaped
[19:09:36] <r00t4rd3d> http://i.imgur.com/AZ1dr.jpg
[19:12:22] <r00t4rd3d> ive since put my controller power supply in the case
[19:12:36] <r00t4rd3d> soon its all going on a rolling cart
[19:25:51] <joe9> taiden: what about removing the hard disk and just running off of livecd?
[19:27:29] <Tom_itx> i'm watching the system monitor on my atom and one cpu was at 100% then i looked back again and it was down to like 12% and the next one was at 100%
[19:27:40] <Tom_itx> does it load balance based on heat or something?
[19:27:58] <Tom_itx> it keeps swapping cpu cores
[19:35:00] <tjb1> Im on budget for my plasma build :)
[19:35:54] <taiden> sorry was afk in the shop
[19:36:37] <taiden> joe9: I dont think it's the HDD but I'm going to do some tests tonight
[19:36:49] <taiden> i'm going to build and order a d525 box tonight
[19:36:55] <taiden> i can't afford to go through this bs again
[19:38:36] <tjb1> I think its about time to design router mounts to cut on the wire edm ;)
[19:40:32] <tjb1> Should the acme screw be contained with the thrust washers are the stepper end or furthest end?
[19:56:27] <_unreal_> hello...
[19:59:56] <_unreal_> any one live?
[20:01:18] <_unreal_> well in any case here is my problem. I just setup EMC2 and all I want is to do direct phase control. I have a simple transistor based stepper motor driver setup. and I cant find any information on how to setup phase control.
[20:02:15] <_unreal_> if I cant get EMC setup them I just have to go with turbocnc. I know it will do every thing I need right out of the box but then I cant use my touch screen monitor. I cant use my trackball mouse and I have to switch to a very low end computer that supports dos
[20:03:47] <_unreal_> hello
[20:06:51] <skorket> I'm having some trouble with my CNC...I'm running grbl on an arduino. Do you guys mind if I ask my question here?
[20:07:57] <r00t4rd3d> ask away
[20:08:39] <r00t4rd3d> skorket, where in upstate are you?
[20:08:45] <_unreal_> r00t4rd3d, any thoughts on my question?
[20:09:30] <r00t4rd3d> i have no clue on phase control
[20:09:52] <skorket> Ithaca, NY. When I turn the dremel on, after about 30 seconds or so I get an error message "port 2 disabled by hub (EMI?), re-enabling..." whereby the arduino running grbl resets. Turning off the dremel fixes the issue. I assume it's noise being introduced by the dremel on the USB line, but I don't know how to fix it
[20:09:54] <r00t4rd3d> others here i am sure do though
[20:09:55] <skorket> any suggestions?
[20:12:12] <r00t4rd3d> bad shielded usb device
[20:12:29] <taiden2> ello gents
[20:12:44] <skorket> well, the arduino is just an open circuit board, basically...would putting it into some sort of housing help?
[20:12:55] <r00t4rd3d> its probably the wires
[20:13:06] <r00t4rd3d> im guessing
[20:13:17] <skorket> the USB wire?
[20:13:21] <r00t4rd3d> are you using shielded motor wires?
[20:13:53] <skorket> no?
[20:14:02] <skorket> for the stepper? No, they're unshielded
[20:14:13] <skorket> *steppers
[20:15:00] <skorket> I did notice the problem gets much worse if the dremel power line is right next to the USB line
[20:15:05] <r00t4rd3d> try powering the arduino with a battery
[20:15:25] <r00t4rd3d> check your grounds are good
[20:15:56] <r00t4rd3d> yeah the usb is getting noise from something
[20:15:58] <skorket> How do I check for good grounds?
[20:16:31] <_unreal_> how are you switching your motor ON/OFF?
[20:16:35] <r00t4rd3d> is there a seperate power/ground for the grbl shield?
[20:16:49] <skorket> _unreal_, by hand...there's a power switch on the dremel
[20:16:53] <_unreal_> what kind of a control circuit, is it to a machanical relay? solid state relay. transistor
[20:17:26] <taiden2> r00t4rd3d: what was the name of the d525 seller on ebay?
[20:17:50] <skorket> The arduino is being powered from over USB, the steppers have a separate power source, the dremel also has a separate power source
[20:18:02] <taiden2> number1kid or something like that
[20:18:12] <skorket> sorry guys, I have to run, I'll be on later. Thanks for the help
[20:18:13] <r00t4rd3d> taiden, http://www.ebay.com/itm/Intel-D525MW-Mini-ITX-Motherboard-w-Atom-525-CPU-/200542103383?pt=Motherboards&hash=item2eb13da757
[20:18:33] <r00t4rd3d> theonlykid1
[20:20:10] <taiden2> thanks r00t4rd3d
[20:24:49] <r00t4rd3d> dont forget that board still needs memory to turn on, but thats it
[20:24:52] <r00t4rd3d> power
[20:25:33] <r00t4rd3d> it takes laptop memory
[20:25:51] <r00t4rd3d> http://www.ebay.com/itm/RAMAXEL-4GB-DDR3-2x2GB-PC3-10600S-1333MHz-Laptop-Memory-Mac-Thinkpad-HP-Dell-RAM-/390449877210?pt=US_Memory_RAM_&hash=item5ae8a050da
[20:27:01] <r00t4rd3d> my d525 with 4gb memory runs windows 7 pretty good
[20:27:35] <r00t4rd3d> i was surprised
[20:28:46] <tjb1> r00t4rd3d: any updates on your router?
[20:28:54] <r00t4rd3d> nope
[20:28:59] <r00t4rd3d> i made a dust shoe
[20:29:11] <r00t4rd3d> and am working on a touch off plate
[20:29:28] <r00t4rd3d> but thats about it
[20:29:36] <tjb1> I ordered everything but the steel for mine
[20:29:55] <r00t4rd3d> what controller?
[20:30:00] <tjb1> g540
[20:30:06] <r00t4rd3d> buy me one
[20:30:18] <tjb1> I bought the 4 axis kit off cncrouterparts
[20:30:21] <tjb1> nema 23
[20:30:24] <r00t4rd3d> wow
[20:30:35] <tjb1> What?
[20:30:42] <r00t4rd3d> high prices
[20:30:51] <r00t4rd3d> but their kits are nice
[20:30:59] <tjb1> Gotta spend money to make money
[20:31:06] <tjb1> Some of his stuff is cheaper to buy than to make
[20:31:11] <r00t4rd3d> yeah
[20:31:17] <r00t4rd3d> i like their motor wires
[20:31:35] <tjb1> Like the drill jig, the drill bushings are like 14-15 each at MSC and his jig is $28 and includes a drill bit
[20:32:15] <r00t4rd3d> they sent me some free stuff
[20:32:29] <r00t4rd3d> when i ordered i asked for some sample products
[20:32:36] <tjb1> Im getting some free stuff as a student discount
[20:32:51] <r00t4rd3d> they sent me some gears that i ended up using
[20:33:06] <tjb1> Probably the gears I need for the r&p drives that are backordered haha
[20:33:17] <taiden2> http://www.amazon.com/Corsair-DDR3-Laptop-Memory-CMSO4GX3M1A1333C9/dp/B002YU83YO/ref=sr_1_1?ie=UTF8&qid=1345684893&sr=8-1&keywords=4gb+ddr3+laptop
[20:33:18] <taiden2> ?
[20:33:19] <r00t4rd3d> 3/8 bore
[20:33:39] <tjb1> I got 110 - M8x23mm t studs with flange nuts and 15 - 5/16 t-nuts as my discount
[20:33:55] <r00t4rd3d> taiden, you see the memory link i posted?
[20:34:23] <r00t4rd3d> that amazon stuff appears to be the right stuff though
[20:34:44] <tjb1> Is it a rack gear?
[20:34:53] <r00t4rd3d> nah
[20:35:15] <r00t4rd3d> http://www.cncrouterparts.com/nema-23-rp-motor-pulley-p-71.html
[20:35:37] <r00t4rd3d> i have it on 3/8 threaded rod
[20:36:32] <tjb1> Oh the one for the belt drive
[20:37:14] <r00t4rd3d> yeah i use it on my z axis
[20:38:19] <r00t4rd3d> are you using their extended carriages and gantry supports?
[20:39:09] <r00t4rd3d> i want to make mine bigger with 4 extended carriages and their supports
[20:42:11] <taiden2> only reason for amazon is i have prime
[20:42:20] <taiden2> and i want to get everything in ASAP
[20:42:35] <taiden2> sadly the D525 seller on amazon stopped offering Prime, so ebay it is on that
[20:42:54] <taiden2> that was why i asked if there were other boards known to be just as good
[20:43:02] <taiden2> hoping to get it in before the weekend
[20:43:13] <taiden2> so im up and ready to go come monday
[20:46:43] <taiden2> okay so
[20:47:00] <taiden2> my atx power supply will work with this sucka?
[20:47:04] <taiden2> i cant see why it wouldn't
[20:52:16] <r00t4rd3d> yeah, just overkill
[20:53:17] <r00t4rd3d> unless you hook up like 5 hard drives and a big pci video card
[20:54:20] <tjb1> Sorry r00t4rd3d had a phone call
[20:54:28] <r00t4rd3d> also there is no ide ports on the d525
[20:54:29] <tjb1> Just the carriages
[20:54:39] <Valen> are you using the atx supply for motor power?
[20:54:46] <tjb1> I bought the smaller carriages and I am going to copy the dimensions to make the longer ones
[20:54:49] <tjb1> $33 is a bit much
[20:55:11] <r00t4rd3d> Valen, his computer
[20:55:34] <Valen> ahh, pfft you could probably run an atom off a handfull of lemons and some coins
[20:56:21] <tjb1> r00t4rd3d: are the carriages 1x4"?
[20:56:32] <Valen> what rails are in use?
[20:56:34] <r00t4rd3d> something like that
[20:56:57] <r00t4rd3d> never measured them
[20:57:10] <tjb1> 7/8x2
[20:57:15] <tjb1> According to his pdf drawing
[20:58:29] <r00t4rd3d> they would be easy to make in hardwood or something
[20:58:38] <tjb1> Any idea what I can expect to pay for 7/8x2 x 5'?
[20:58:52] <tjb1> mcmaster only has that with material certification...
[20:59:05] <r00t4rd3d> i could get that from my local guy cheap
[20:59:10] <r00t4rd3d> less then 100
[20:59:26] <r00t4rd3d> dirt included
[21:00:13] <tjb1> It was $84 for the 6' piece with mat cert
[21:01:29] <r00t4rd3d> i used aluminum for my rails
[21:03:10] <tjb1> only $52 for a 6' of 1x2 at onlinemetals
[21:03:20] <tjb1> so hopefully I can get 7/8x2 locally or see if the school has it
[21:03:37] <r00t4rd3d> go steal a stop sign and cut it up
[21:04:11] <Valen> question for the hivemind, I'm sprucing up my missus motorbike, however around the ignition barrel and such theres a number of little plastic parts that look like the paint is screwed on them
[21:04:21] <tjb1> Cut it up and melt it?
[21:04:22] <tjb1> lol
[21:04:23] <Valen> any suggestions for the best way to repaint it?
[21:04:43] <Valen> its all mystery plastic unfortunatly
[21:04:57] <r00t4rd3d> plastic coat spray paint
[21:05:07] <tjb1> krylon plastic paint
[21:05:37] <r00t4rd3d> "plastikote" is the proper name i guess
[21:05:38] <tjb1> r00t, what am I going to do with a stop sign?
[21:05:45] <r00t4rd3d> get arrested
[21:05:57] <r00t4rd3d> or make some rails
[21:05:59] <tjb1> I have a road sign
[21:06:04] <tjb1> ;)
[21:06:09] <Valen> comes in rattlecan format too
[21:06:20] <Valen> I was debating if i should use rattlecan car paint
[21:06:33] <tjb1> There is a person on this forum I go to, painted there hood with plastikote
[21:07:22] <r00t4rd3d> some self etching primer wouldnt hurt either
[21:07:30] <Valen> looks like regular paint that plastikote?
[21:07:37] <Valen> i was thinking of an etch primer
[21:07:53] <r00t4rd3d> i like the dupont stuff but its expensive, more then the paint
[21:08:09] <Valen> the other criteria is rattle can lol
[21:08:19] <r00t4rd3d> http://www.johnsonautobodysupply.com/media/products/DUP-A-4115S-Self-Etching-Primer-LG.jpg
[21:08:29] <r00t4rd3d> that stuff is awesome primer for metal/plastic
[21:08:34] <Valen> i have to cover an area about the size of my face lol
[21:09:26] <r00t4rd3d> http://www.johnsonautobodysupply.com/Plastics-Adhesion-Promoter.html
[21:09:52] <r00t4rd3d> hmm never seen that stuff before
[21:10:56] <taiden2> now the 450 watt powersuply will only draw that much power if the computer requires it, correct?
[21:11:07] <taiden2> it's not just going to be burning through 450 watts of power 24/7
[21:11:07] <Valen> sorta kinda
[21:11:10] <Valen> no
[21:11:20] <Valen> the atom will probably pull ~15W
[21:11:26] <taiden2> Lol
[21:11:32] <taiden2> i'm going atom + ssd
[21:11:33] <Valen> the psu at the wall probably ~80
[21:11:42] <Valen> dont get an ssd for reliability
[21:11:49] <Valen> unless its being bashed around
[21:11:51] <taiden2> seriously?
[21:11:54] <taiden2> i thought they were way more reliable?
[21:11:59] <Tom_itx> seriously
[21:12:08] <taiden2> learn something new every day
[21:12:15] <Valen> first actual results are they are about on par with spinning media
[21:12:35] <taiden2> for total failure or
[21:12:39] <taiden2> for longevity of blocks
[21:12:43] <r00t4rd3d> you can get giant sata drives cheap too nowadays compared to small ass ssd drive
[21:12:53] <tjb1> taiden2, what size ssd
[21:12:59] <taiden2> 30gb
[21:13:00] <taiden2> vs 160gb hdd
[21:13:02] <Valen> total failure
[21:13:04] <taiden2> same price
[21:13:06] <tjb1> Too bad you didn't tell me earlier
[21:13:14] <tjb1> There was a 60gb ssd for $48 earlier
[21:13:23] <taiden2> i just dont need anything bigger
[21:13:31] <Valen> theres plenty of other reasons to get an SSD vs a hdd
[21:13:33] <taiden2> it is for cnc use alone
[21:13:40] <Valen> just reliability isn't one of them ;->
[21:13:54] <taiden2> the zippy nature of it was attractive
[21:13:54] <tjb1> I have had a 120gb in my computer for over a year now no problems
[21:13:56] <Valen> if you can get it for the same price for a CnC then by all means
[21:14:06] <taiden2> and also the whole no moving part vs dust thing
[21:14:08] <tjb1> I am pissed that it cost me $240 though
[21:14:25] <Valen> dont let dust into your computer enclosure
[21:14:33] <r00t4rd3d> lol
[21:14:34] <taiden2> easier said than done :)
[21:14:36] <r00t4rd3d> yeah
[21:14:42] <Valen> do it anyway
[21:14:42] <r00t4rd3d> http://www.ebay.com/itm/New-1TB-1000GB-16MB-Cache-7200RPM-SATA2-3-5-Desktop-Hard-Drive-FREE-SHIPPING-/120848988382?pt=US_Internal_Hard_Disk_Drives&hash=item1c232938de
[21:14:45] <tjb1> taiden2: keep an eye out here - http://www.woot.com/
[21:14:46] <Valen> its not that hard anyway
[21:14:54] <Valen> just put it all in a sealed box
[21:14:56] <taiden2> tjb1 it's time sensitive sadly
[21:15:03] <tjb1> They are having a woot off today
[21:15:10] <tjb1> Thats where the 60gb was for $48
[21:16:48] <tjb1> It was actually 45.99
[21:16:52] <tjb1> corsair 60gb
[21:18:05] <tjb1> taiden2: http://www.corsair.com/us/outlet-store/refurbished-ssds/force-series-f60b-solid-state-hard-drive-factory-reconditioned.html
[21:18:09] <tjb1> There ya go.
[21:18:16] <r00t4rd3d> you should get a big usb hub and add lots of toys
[21:18:25] <r00t4rd3d> fans, lights etc
[21:18:57] <r00t4rd3d> burn that 450w
[21:19:05] <Jymmm> 30 day warranty
[21:19:10] <taiden2> well
[21:19:22] <Jymmm> not even 90 day, eeeesh
[21:19:26] <taiden2> i figure i can make a little break out for 12v etc using the power supply
[21:19:32] <taiden2> for things like relay triggers etc
[21:19:35] <taiden2> so it might not be the worst idea
[21:19:59] <tjb1> Jymmm: Just gotta pound it hard in the first 30
[21:20:20] <taiden2> plus using it would save me $50
[21:20:25] <taiden2> which is always nice haha
[21:21:59] <r00t4rd3d> http://www.ebay.com/itm/Retro-Clear-Game-Controller-red-LED-USB-Atari-Joystick-Mac-PC-/280901728803?pt=Video_Games_Accessories&hash=item41670c3a23
[21:22:28] <r00t4rd3d> that is cool, i like how you can remove the board and use it in a mame cabinet
[21:22:48] <taiden2> that is sweet
[21:22:54] <taiden2> i was going to make a mame cabinet
[21:22:57] <taiden2> never got around to it
[21:23:46] <r00t4rd3d> im gonna make a mini one sometime
[21:24:05] <Jymmm> http://www.newegg.com/Product/Product.aspx?Item=N82E16820148441
[21:25:12] <jdh> anyone returned anything to newegg.
[21:25:24] <r00t4rd3d> i dont think you would benefit much from the speed a ssd offers
[21:25:41] <r00t4rd3d> not with a mini itx board
[21:26:18] <_unreal_> damn!! ok finally got some motion out of my cnc machine using turbo
[21:26:48] <_unreal_> first time an AXIS has worked on my cnc machine and wow is it powerful
[21:26:54] <r00t4rd3d> unreal you should ask your question again now that more people are active
[21:27:10] <jdh> I misordered somethingg from newegg ($75 item ) had to pay $9.50 shipping and $12 restockifee
[21:27:17] <r00t4rd3d> lol
[21:27:36] <r00t4rd3d> bitch and complain
[21:27:48] <_unreal_> I'd like to get EMC2 working with direction phase control instead of step/dir..... there seems to be no info on the internet. currently the only way I can even make the machine move is using turbocnc... mainely because I have only built a simple transistor motor driver
[21:27:56] <jdh> I did. They offered me a gift card for thhe restock fee
[21:28:31] <_unreal_> I also have to modify some wires it seems I have muxed some up.... sigh
[21:28:46] <jdh> what is direction phase control?
[21:28:53] <jdh> cw/ccw?
[21:30:38] <tjb1> This is descriptive… http://wwwapps.ups.com/WebTracking/processInputRequest?sort_by=status&tracknums_displayed=1&TypeOfInquiryNumber=T&loc=en_us&InquiryNumber1=1Z0835200339470120&track.x=0&track.y=0
[21:31:00] <r00t4rd3d> im gonna call now and reroute that tracking number to my house
[21:31:06] <r00t4rd3d> :D
[21:31:10] <tjb1> Good luck
[21:31:13] <tjb1> :)
[21:31:28] <tjb1> Thats the least information I have ever gotten from a UPS tracking number
[21:31:36] <r00t4rd3d> it updates
[21:31:42] <tjb1> I had to call mcmaster to get it...
[21:32:04] <jdh> it hasn't gone anywhere yet
[21:32:04] <tjb1> Still dunno how much I paid to ship it
[21:32:21] <jdh> invoice should be available.
[21:32:29] <tjb1> jdh: It "says" it hasn't gone anywhere yet
[21:32:34] <tjb1> Nope, nothing on the site
[21:33:02] <jdh> you ordered this afternoon?
[21:33:26] <tjb1> yesterday afternoon
[21:33:37] <jdh> that's pretty bad for mcmaster
[21:34:08] <taiden2> i want to grab a heatsink for my gecko while im on amazon
[21:34:30] <taiden2> is there a name for large chunks of heatsink material?
[21:34:31] <tjb1> Yeah, it told me it had shipped this morning and I called at 7pm to get the tracking info
[21:34:50] <tjb1> I hate looking for stuff like that on amazon, you'll have better luck on ebay :)
[21:35:13] <Valen> mcmaster wont ship to me anymore because i'm an evil forrign terrorist
[21:35:34] <jdh> http://www.cnczone.com/forums/attachment.php?attachmentid=83347&d=1245765187
[21:35:42] <taiden2> i explative love mcmaster
[21:35:54] <Valen> I've never understood the whole american thing of not shipping internationally
[21:35:56] <tjb1> Anyone ever wrangle a catalog from them?
[21:36:04] <Valen> is writing another line on the address really that hard?
[21:36:09] <jdh> I've gotten print and cd versions
[21:36:10] <tjb1> Where can I buy that jdh
[21:36:13] <Tom_itx> i used to have one
[21:36:16] <Tom_itx> err have an old one
[21:36:18] <jdh> Valen: it's not just a line, it's a pain in the ass.
[21:36:38] <tjb1> Yes, I agree…just shipping to canada was a pain in the ass
[21:36:47] <jdh> tjb1: homanndesign (.au I think) I assuem others sell them also.
[21:36:52] <Valen> how is it any harder?
[21:36:58] <tjb1> Bunch of customs bs
[21:36:58] <Jymmm> Valen: CN22
[21:37:15] <jdh> customs forms, dealing with the desk clerk
[21:37:22] <Jymmm> Valen: customs declaation form, wiating in line at the PO
[21:37:42] <tjb1> jdh: http://www.homanndesigns.com/store/index.php?main_page=product_info&cPath=24&products_id=75
[21:38:01] <tjb1> Forms for origin of product of materials and other crap
[21:38:07] <taiden2> shipping international is a HUGE pain in the ass
[21:38:18] <taiden2> if paypal didn't handle customs forms for me I wouldn't ship international
[21:38:25] <tjb1> Only $32, wonder how bad shipping is…is the G540 really that prone to getting hot?
[21:38:29] <taiden2> but im the rare exception to USA shipping methods
[21:38:33] <Valen> wow it must suck to be you guys
[21:38:33] <taiden2> i ship international for free
[21:38:50] <jdh> tjb: http://www.soigeneris.com/G540_Heak_Sink_Kit-details.aspx
[21:38:53] <Valen> if i want to post something internationally i basically write another line on the address
[21:39:00] <jdh> did you read the gecko heat sink article?
[21:39:00] <taiden2> i just know that 40% of my customers are international
[21:39:05] <Jymmm> Valen: a package or a letter?
[21:39:10] <Valen> parcel
[21:39:10] <taiden2> and calculate average shipping
[21:39:12] <tjb1> Valen: This is why people in the US don't ship out
[21:39:13] <taiden2> and tack that onto the price
[21:39:32] <taiden2> comes out in the wash
[21:39:34] <Valen> we always fill out dangerous goods stuff when shipping anything faster than snailmail
[21:39:39] <tjb1> But funny, I have ordered stuff from china that they paid more to ship it than the item cost
[21:39:50] <Valen> also we generally don't use courier services
[21:39:51] <Valen> they suck
[21:39:58] <Valen> and charge you assloads for stuff like customs
[21:40:18] <taiden2> Valen, what do couriers cost?
[21:40:33] <Valen> fedex is ~3-4x the price of australia post
[21:40:45] <Valen> speed is 3-5 days vs 5-10
[21:40:46] <tjb1> Whoa…no thanks jdh, $27 shipping for that fan kit
[21:41:01] <Jymmm> WHAT?
[21:41:38] <jdh> tjb1: read the gecko heat sink article first
[21:42:16] <taiden2> tjb1: i am almost sure that i burned out my z axis because i didn't properly cool my g540
[21:42:17] <tjb1> Got a link that works?
[21:42:29] <Jymmm> tjb1: $27.80 here
[21:42:44] <tjb1> Jymmm: your in the US also?
[21:42:47] <Jymmm> 67.43 express
[21:42:54] <Jymmm> tjb1: SFO
[21:42:54] <taiden2> tjb1: i was pretty pissed because they don't explicitly state in the user manual to use a heatsink, they basically say "you might need a heatsink, read this article that there is no link to to find out how important it is"
[21:43:10] <taiden2> tjb1: i stopped reading at "you might"
[21:43:11] <Jymmm> taiden2: they actually do
[21:43:12] <jdh> the article says a heatsink isn't needed, just a fan is fine.
[21:43:28] <tjb1> San Fran?
[21:43:36] <Jymmm> tjb1: jes
[21:43:46] <taiden2> it is my personal opinion that the heatsink section of the g540 manual is not in any way explicit
[21:43:46] <tjb1> If he can do better than $27 ill be interested
[21:43:50] <taiden2> not in the way it should be
[21:43:55] <taiden2> it should say
[21:43:59] <tjb1> Not a lot of money to protect the $290 controller
[21:44:00] <taiden2> HEY DUMBEXPETIVE
[21:44:02] <taiden2> USE A HEATSINK
[21:44:05] <jdh> $250 controller.
[21:44:13] <Jymmm> tjb1: I'd rather use a nice huck of aluminum instead, will never break
[21:44:20] <jdh> http://www.geckodrive.com/g540-heatsinking
[21:44:25] <tjb1> jdh: only if you spend all day on ebay :P
[21:44:30] <jdh> doesn't it say 'read the heat sink article'?
[21:44:37] <taiden2> it says
[21:44:45] <taiden2> you may need a heatsink
[21:44:48] <jdh> tjb1: they are $250 at keling/automationtechnology
[21:44:57] <taiden2> there is an article online about our findings
[21:44:59] <taiden2> it doesn't say
[21:45:01] <taiden2> USE A HEATSINK
[21:45:07] <taiden2> three words would have been nice
[21:45:21] <Tom_itx> me offeres his advice: http://tom-itx.dyndns.org:81/~webpage/cnc/psu/heatsink_bulk.jpg
[21:45:29] <Jymmm> taiden2: I sent you scrncaps if it DOES say it.
[21:45:37] <taiden2> tom where did you find it?
[21:45:48] <Tom_itx> scrap yard
[21:46:00] <taiden2> care to spare a 6" x 3" piece? :D
[21:46:11] <Tom_itx> where are you?
[21:46:15] <taiden2> Maine, USA
[21:46:19] <Tom_itx> maybe
[21:46:21] <tjb1> Ill try to work on him to get lower than $27
[21:46:25] <Jymmm> http://www.ebay.com/itm/11-5-W-x-3-L-Heatsink-DIY-HIFi-Amp-Power-Transistors-/370641095905?pt=LH_DefaultDomain_0&hash=item564bee4ce1
[21:46:30] <tjb1> Anyone in US interested in a group buy on that chiller?
[21:46:41] <jdh> tjb1: read http://www.geckodrive.com/g540-heatsinking first

[21:54:17] <tjb1> This year

[21:54:36] <Jymmm> tjb1: Ok, just asking =)
[21:55:38] <Jymmm> I installed latest desktop ubuntu to a usb stick from mac. Booted my netbook from it, not too shabby.
[21:57:50] <Jymmm> These are just awesome (have 4 of em) http://www.dealextreme.com/p/kawau-world-s-smallest-microsd-transflash-tf-sd-sdhc-usb-2-0-card-reader-keychain-25558
[21:58:12] <Jymmm> such a low profile you cna boot from them and just leave them in place.
[21:58:43] <_unreal_> ok finished doing my re-soldering
[21:58:56] <_unreal_> GOD!! I need a chopper driver so bad
[21:59:25] <Jymmm> call your local helipad
[21:59:28] <_unreal_> I have a 30v 6a switching supply that is screaming at me
[21:59:50] <_unreal_> ! I think I'll TRY modding the INI in turbo again
[22:00:42] <jdh> what driver are you using?
[22:02:51] <_unreal_> jdh? you talking to me
[22:02:54] <jdh> yes.
[22:03:02] <_unreal_> :) heheh your going to laugh
[22:03:45] <_unreal_> alldatasheet mp4301 3X
[22:04:00] <_unreal_> with 1k resistors between PC and base pins :)
[22:04:36] <_unreal_> works DAMN good but I'm really lacking in power and my dropping resistors are EATING up watts horid :(
[22:05:03] <Tom_itx> that doesn't sound good
[22:06:22] <jdh> whatever works for you.
[22:06:24] <_unreal_> my PSU for now is a 2X switching mode PSU 30v/3.1A I have both of them tied in parallel with a massive DIODE on the +v lines so I dont get back feeding from the supplies
[22:06:35] <jdh> what voltage are you feeding the motors?
[22:07:38] <_unreal_> I have a few transformers but I dont know if they will even handle the supply need
[22:08:02] <_unreal_> my motors are all huge most of them rated for 8v 1.5A
[22:08:15] <_unreal_> unipolar
[22:08:37] <jdh> geez... get some cheap drivers.
[22:09:08] <_unreal_> I have not a penny to my name
[22:09:08] <r00t4rd3d> tb6560
[22:09:23] <_unreal_> lay off after layoff after layoff
[22:09:30] <r00t4rd3d> sell crack
[22:09:33] <_unreal_> I've been laid off 4 times in 3 years
[22:09:42] <jdh> that sucks.
[22:09:49] <Jymmm> _unreal_: invest in fishnet
[22:10:06] <_unreal_> I'm about to loose my apartment becuase i'm almost 3k in the hole with my land lord
[22:10:30] <r00t4rd3d> then what?
[22:10:32] <r00t4rd3d> welfares?
[22:11:18] <_unreal_> dont know
[22:11:28] <_unreal_> I have been told pay up or get out
[22:12:05] <_unreal_> I hate the state I live in but I cant do any thing because I have a POS X wife thats on her 4 or 5th BF that I know of. and 3rd home and we have a 3yo :(
[22:12:29] <_unreal_> divorced 1 year in sept
[22:12:41] <r00t4rd3d> you should have killed her for the insurance money when you had the chance
[22:20:21] <_unreal_> any one ever had a KT7-RAID?
[22:20:26] <r00t4rd3d> http://www.liveleak.com/view?i=abb_1345687803
[23:21:19] <r00t4rd3d> cricket
[23:28:30] <Jymmm> _unreal_: is htat the amd mobo raid controller?
[23:30:16] <skorket> r00t4rd3d, The USB is connected to a computer which is powered by it's own power supply. Do you think that the motor is really sending so much noise that the computer's power supply can't handle it?
[23:43:02] <r00t4rd3d> it might screw with the usb
[23:43:16] <r00t4rd3d> use a battery to power the arduino to see
[23:46:01] <skorket> anyway to test?
