[02:14:32] <DJ9DJ> moin
[05:34:13] <Loetmichel> mornin' from the company
[05:38:44] <Loetmichel> .working on sundays... hate it... ans i am payed for mo-fr 8 to 5... :-(
[05:45:57] <r00t4rd3d> say no
[05:47:38] <archivist> bosses take advantage of good workers willing to do that bit extra, hope there are bonuses
[06:05:45] <Loetmichel> bonuses?
[06:06:21] <Loetmichel> boss: "tell me when your car is empty, i will fill her up..."
[06:07:43] <archivist> free fuel would count a a bonus
[06:19:55] <r00t4rd3d> http://i.imgur.com/XQUG5.jpg
[06:20:03] <Loetmichel> archivist. NOT IF ITS INSTEAD OF PAYING THE OVERTIME::: .-9
[06:20:14] <Loetmichel> ups, capslock
[06:20:29] <r00t4rd3d> I would say I will tell you when my wallets empty, you can fill that up.
[06:23:05] <archivist> my wallet has been empty for a few years
[06:37:22] <r00t4rd3d> lay off the crack
[06:43:41] <Loetmichel> r00t4rd3d: ?
[06:44:16] <r00t4rd3d> ?
[06:44:30] <Loetmichel> [13:27] <r00t4rd3d> lay off the crack <- ?
[06:44:50] <r00t4rd3d> crack cocaine?
[06:44:56] <r00t4rd3d> rock
[06:45:26] <r00t4rd3d> surely you have smoked some crack in your time
[06:45:28] <Loetmichel> i know. i meant: why are you suggesting i would take such stuff?
[06:45:33] <Loetmichel> never
[06:45:44] <Loetmichel> some grass, but nothing harder
[06:46:25] <r00t4rd3d> and actually i was suggesting archivist was taking such stuff.
[06:46:44] <DaViruz> hence his wallet being empty
[06:48:11] <Loetmichel> ah, i see
[06:48:53] <r00t4rd3d> if you are working sundays for free, you might as well start smoking some too
[06:48:53] <r00t4rd3d>
[06:49:35] <r00t4rd3d> or kick it up a notch to bath salts
[06:53:21] <Loetmichel> hrhr
[06:56:41] <Loetmichel> <- to cheap to do drugs
[06:57:06] <Loetmichel> tobacco is expensive enough
[06:57:08] <Loetmichel> ;-)
[06:57:44] <r00t4rd3d> where do you live?
[06:57:57] <Loetmichel> germaqny
[06:58:05] <r00t4rd3d> wtf is that
[06:58:09] <r00t4rd3d> :D
[06:58:17] <Loetmichel> -q
[06:59:29] <Loetmichel> i am typing one-handed (the other is working) over a vnc... cut me some slack
[07:00:24] <r00t4rd3d> what are you doing over vnc?
[07:01:11] <Loetmichel> accessing my home pc where mirc is running
[07:01:26] <r00t4rd3d> mircs nasty, ur nasty.
[07:02:06] <Loetmichel> so what?
[07:08:38] <ReadError> crack cocaine will fry your brain!
[07:10:56] <r00t4rd3d> how do i determine my best plunge rate
[07:11:17] <WillenCMD> what material?
[07:11:28] <r00t4rd3d> wood
[07:12:30] <WillenCMD> i usually plunge at half the feed for the x&y its good starting point, my theory is go balls to the wall, if it chips a cutter back it off 10%
[07:13:30] <WillenCMD> but then i work a production shop and time is money, and when i get through a 1
[07:14:06] <WillenCMD> inch plate of 1018 with a half inc insert mill, they whole shop can hear, they say sounds like shit, i say its only noise
[07:14:31] <WillenCMD> just cut it off like a jig saw :)
[07:24:04] <r00t4rd3d> http://www.filedropper.com/stewie
[07:24:17] <r00t4rd3d> cut that on a production machine
[07:26:05] <WillenCMD> is that a picture or just the Gcode
[07:27:50] <ReadError> r00t4rd3d
[07:27:53] <ReadError> imgur foo
[07:28:10] <ReadError> of the product
[07:28:41] <r00t4rd3d> just something i made in microcarve
[07:29:03] <r00t4rd3d> gcode
[07:29:38] <r00t4rd3d> lets see who can do it the best
[07:30:29] * r00t4rd3d breaks out my tiny balls
[07:32:22] <r00t4rd3d> http://pauseliveaction.files.wordpress.com/2010/02/stewie1.jpg
[07:32:30] <r00t4rd3d> that is the image i used to make it
[07:33:28] <r00t4rd3d> its only like 200k lines
[09:09:33] <Tom_itx> ReadError i think it already has
[09:10:51] <Tom_itx> r00t-Shed my cad cam calculates the plunge rate at half the feedrate however i can override it
[09:11:22] <Tom_itx> the trick is to have your z clear as close to the material as safe
[09:13:59] <ries> awallin: happen to be here?
[09:14:07] <r00t-Shed> ahhhhhh
[09:16:23] <Tom_itx> r00t-Shed why would you post a 5.5M file of stewie that nobody will likely run?
[09:17:04] <Tom_itx> i certainly wouldn't, not knowing more about the file
[09:28:18] <geo01005> microcarve
[09:28:33] <geo01005> is there a big difference between the performance of microcarve vs image2gcode?
[09:30:27] <JT-Shop> what kind of performance?
[09:31:17] <Tom_itx> how it interprets the image?
[09:31:25] <geo01005> I'm trying to understand why someone would use microcarve rather than image2gcode.
[09:40:32] <r00t4rd3d> i tried image2gcode but cant remember why i didnt like it
[09:40:47] <Tom_itx> JT-Shop do you know if the input on the encoder in hostmot2 can be inverted?
[09:40:54] <Tom_itx> my sensor switches ground
[09:41:11] <Tom_itx> maybe a pullup on the pin would work
[09:41:25] <JT-Shop> Tom_itx: I don't know
[09:41:29] <Tom_itx> it's on the 7i47
[09:42:09] <Tom_itx> i'm only using the A channel
[09:42:37] <Tom_itx> gave up around midnight but i wasn't getting any signal input
[09:42:46] <Tom_itx> i tested it with an led and that was ok
[09:44:20] <Tom_itx> i wonder how the differential input works on the 7i47 if you're using the resistor divider thing to fool it
[09:44:33] <Tom_itx> i thought about tying it to the /A input instead of A
[09:48:07] <anonimas1> Tom_itx: it works good..
[09:48:17] <Tom_itx> what does?
[09:48:33] <anonimas1> with a resistor divider
[09:48:57] <Tom_itx> i am using that on other inputs but using the + input on them
[09:49:11] <anonimas1> but i beleive there is a inverted signal avaiable for the encoder input also or maybe im wrong
[09:49:14] <Tom_itx> would i need to reverse the divider if i put it on the + side to use the - side?
[09:49:25] <anonimas1> that I cant say sorry
[09:49:37] <Tom_itx> it's not a 50/50 divider
[09:50:44] <Tom_itx> it's an open collector sensor
[09:50:52] <Tom_itx> so i will try the pullup first
[09:50:58] <JT-Shop> Tom_itx: start your config and open up show hal configuration and see what pins and parameters you have for the 7i47
[09:51:16] <Tom_itx> JT-Shop what do you mean?
[09:51:25] <Tom_itx> i know what you're asking..
[09:51:35] <Tom_itx> but i don't see how that will help
[09:51:47] <Tom_itx> i didn't see anything about invert
[09:51:51] <Tom_itx> except on the index
[09:51:53] <JT-Shop> if there is an invert is not that what you seek
[09:52:04] <JT-Shop> did you check the parameters too
[09:52:12] <Tom_itx> no
[09:52:16] <Tom_itx> just the docs for it
[09:52:36] <Tom_itx> well, yes i guess so
[09:52:38] <Tom_itx> ;)
[09:52:50] <Tom_itx> just the index-invert was all
[09:53:16] <Tom_itx> i think it needs a pullup
[09:53:42] <Tom_itx> because on a pulse train invert may not matter as much as a single shot signal
[09:54:37] <Tom_itx> i set the scale for the disk
[09:54:51] <Tom_itx> and set counter-mode for single channel
[09:56:43] <r00t-Shed> http://i.imgur.com/j9XSG.png
[09:57:00] <r00t-Shed> please someone tell my why that G92 is out in outer space
[09:57:11] <r00t-Shed> or better yet how to correct it
[09:57:51] <Tom_itx> set values for G54?
[09:58:40] <pcw_home> If you have an open collector drive to a 7I47 input used in TTL mode , you will need a pullup (or you will not get any signal)
[09:58:40] <r00t-Shed> how?
[09:58:47] <Tom_itx> touch off
[09:59:02] <Tom_itx> pcw_home you are so right :D
[09:59:16] <r00t-Shed> touch off what
[09:59:26] <Tom_itx> i figured it was that, i'm digging for one as we type
[09:59:37] <Tom_itx> touch off G54 x y offsets
[09:59:43] <Tom_itx> maybe you did already
[09:59:53] <r00t-Shed> back to how
[10:00:27] <Tom_itx> select the axis on your manual control and push the touch off button
[10:00:36] <r00t-Shed> yean nvm :D
[10:00:40] <Tom_itx> after you're where you wanna be of course
[10:01:05] <r00t-Shed> its on p1g54
[10:01:16] <r00t-Shed> thats what its always set at
[10:02:41] <Tom_itx> pcw_home, 330 ohm strong enough?
[10:02:56] <pcw_home> depends on your sensor
[10:03:20] <pcw_home> 7I47 is high impedance so does not care too much
[10:03:25] <Tom_itx> i couldn't find a data sheet on it but it's cmos
[10:03:26] <r00t-Shed> cradek, you around?
[10:03:47] <Tom_itx> 4.5-16v input
[10:04:57] <Tom_itx> it's sister was an Omron EE SX3133
[10:05:20] <Tom_itx> specs seemed to hold true to it
[10:06:43] <pcw_home> bbl
[10:11:02] <jthornton> looks like my WAG was totally off
[10:27:38] <Tom_itx> 1k fixed it
[10:27:47] <Tom_itx> now i see counts in hal conf
[10:28:17] <Tom_itx> now for JT-Shop's expertice
[10:28:30] <Tom_itx> how to get rpm on the axis screen :)
[10:35:43] <JT-Shop> like a speed-o-meter or just a number?
[10:40:02] <Tom_itx> both
[10:40:10] <Tom_itx> bar and number
[10:40:15] <Tom_itx> either
[10:40:19] <Tom_itx> spedo would be ok
[10:40:33] <Tom_itx> figure max at 6000
[10:40:43] <Tom_itx> i think that's close but it may only be around 5
[10:41:11] <Tom_itx> i looked at them a bit but was waiting to get it working
[10:41:36] <JT-Shop> you got a pyvcp screen now?
[10:42:01] <Tom_itx> yeah
[10:42:12] <Tom_itx> the files are in place
[10:43:48] <Tom_itx> although i don't remember where they're all at
[10:45:27] <Tom_itx> postgui.hal?
[10:46:30] <JT-Shop> that is where you would make the hal connections for the pyvcp stuff
[10:46:42] <JT-Shop> xml is the pyvcp file
[10:47:26] <atom1> should it be in the config directory?
[10:47:30] <atom1> i don't see one
[10:47:52] <atom1> oh there it is.. display.xml
[10:53:04] <atom1> does the encoder.n.velocity output prescale the number by your encoder resolution?
[10:53:21] <atom1> i think it does
[10:55:08] <JT-Shop> spindle?
[10:55:53] <atom1> yes
[10:57:09] <JT-Shop> mine postgui is net spindle-rpm => pyvcp.spindle-speed
[10:58:19] <atom1> does it come from hostmot2 encoder input?
[10:59:04] <JT-Shop> trying to find it now
[10:59:51] <atom1> i'd also like to display an active number below it
[11:01:16] <JT-Shop> my spindle for the CHNC
http://pastebin.com/KvuRtWk6
[11:03:26] <atom1> are you using an analog sensor for it?
[11:03:39] <atom1> sorta looks like it
[11:03:51] <atom1> with the 10v scaling you have
[11:03:55] <JT-Shop> my spindle is a servo
[11:04:14] <JT-Shop> with encoder feedback
[11:08:48] <atom1> JT-Shop, did you put your spindle-speed line in the posgui.hal ?
[11:09:52] <JT-Shop> <JT-Shop> mine postgui is net spindle-rpm => pyvcp.spindle-speed
[11:11:41] * JT-Shop falls pray to the napster..........
[11:18:35] * FinboySlick calls the MPAA.
[11:18:49] <FinboySlick> Crap, I mean the RIAA.
[11:20:48] <Jymmm> FinboySlick: He said Napster, not Torrent =)
[11:21:04] <Jymmm> FinboySlick: Napster is now legit
[11:21:19] <FinboySlick> What has the world come to...
[11:21:42] <Jymmm> chaos
[11:23:34] <Jymmm> Does anyone have a good way to debur the inside of 1/4" SS Tubing ?
[11:24:10] <archivist> taper reamer
[11:24:38] <Jymmm> I think I have one of those, thanks =)
[11:25:01] <jdh> doesn't really work so great on this application.
[11:25:02] <Jymmm> Though I havne't seen it in a while, might be on the bottom of the drawer.
[11:25:11] <jdh> you just push the burr in, not break it off
[11:26:11] <archivist> or one buys one of those useless deburring tools
[11:26:38] <Jymmm> I have one, but on SS, it's gonna be ever MORE useless
[11:26:57] <Jymmm> especially on this thick walled tubing
[11:28:50] <jdh> there isn't much room to insert a reamer. For the most part it won't matter though. I have used lots of 1/4" thick walled SS tubing for high pressure oxygen and a burr breaking off inside can lead to an O2 fire.
[11:29:29] <Jymmm> jdh: explain?
[11:29:35] <jdh> which part
[11:29:39] <Jymmm> fire
[11:30:26] <FinboySlick> Jymmm: Don't yell fire in a crowded channel.
[11:30:27] <Jymmm> burr gets trapped in a valve?
[11:30:40] <Jymmm> FinboySlick: HI JACK!
[11:30:47] <jdh> impingement, coupled with adiabatic heating and any fuel source can lead to a mostly uncontrollable fire
[11:32:05] <Jymmm> jdh: But how can the burr break loose in an O2 line, and cause a fire? What's the ignition point?
[11:32:27] <jdh> flow induced vibration
[11:33:21] <Jymmm> jdh: Ok, is the vibration strong enough to cause friction?
[11:33:31] <jdh> the ignition point would be any flammable substance in the system. leftover lube, grease, leftover goop from sticky fingers.
[11:34:01] <jdh> no, when the burr breaks loose, and flies, hits a restriction and speeds up, the impingement can cause enough heat to flash
[11:34:16] <Jymmm> ah, ok
[11:34:30] <jdh> if there is enough low-flashpoint fuel, the metal will start burning
[11:34:55] <atom1> ok now to get the scaling right
[11:35:08] <Jymmm> jdh: "But but but O2 it hard to ignite" ;)
[11:35:24] <jdh> o2 is impossible to ignite, it isn't flammable
[11:38:14] <jdh> http://www.youtube.com/watch?v=SaBghGKAOBo
[11:39:54] <jdh> I had some pictures from an o2 panel fire at a dive shop in florida. All stainless plumbing. Something flashed and the steel panel started burning
[11:45:37] <Jymmm> jdh: I guess I've always thought of O2 as "flammable", even while knowing about fire triangle. but it's an oxidizer, not a fuel (as I just read). It seems a lot of ppl think the same way.
[11:46:16] <Jymmm> ...or at least should be treated/handled as if it were flammable.
[11:47:42] <jdh> yep
[11:48:02] <IchGuckLive> hi all around the globe
[11:49:21] <jdh> unfortunately, I know enough people that have been killed/injured from o2 related accidents, that I am fairly attentive to my own o2 filling methods.
[11:50:30] <IchGuckLive> o2 needed for ?
[11:50:37] <jdh> diving
[11:50:47] <Jymmm> jdh: I saw the video, but I still not get how a fire could start. Ok, you have a partical come loose, hit an internal part of the regulator, but there is only so much room/flammable material available. How it gets to 2000F+ to melt metal, I have nfc. Is there an exotic metal in here I'm missing? magnestium, etc?
[11:51:10] <IchGuckLive> jdh: arend there speceal people that refill this cans
[11:51:21] <IchGuckLive> in germany its not allwed to do it your own
[11:51:22] <jdh> IchGuckLive: I'm pretty special!
[11:51:26] <Jymmm> magnestium <--- The newest element =)
[11:52:27] <jdh> Jymm: valve seats, cumulative contamination from multiple fills, o-rings. They used to make some o2 reg parts out of aluminium, but they are mostly all brass now
[11:52:56] <Jymmm> jdh: So it's specifically an interaction with the aluminum?
[11:53:17] <jdh> or one of the above.
[11:53:38] <jdh> There are some regulators made of titanium alloys that are not good for o2
[11:54:13] <Jymmm> jdh: So it's the ".....um" that can fuck you up?
[11:54:20] <jdh> and no scuba valve is really good for oxygen. The flow path is bad and seat materials are not great.
[11:55:10] <jdh> yeah. like any fire prevention thing. you try to eliminate heat & fuel, you can't eliminate the o2
[11:56:05] <Jymmm> jdh: Sure, but this all sounds like Class D fire stuff.
[11:56:15] <Jymmm> above my paygrade
[11:56:22] <jdh> even it doesn't explode or burn, a tiny flash of grease or nylon burning while filling a dive tank can release nasty stuff that will kill you at depth.
[11:56:49] <jdh> the fire is definitely D, but they usually self-extinguish.
[11:56:54] <Jymmm> I bet.
[11:57:55] <Jymmm> Yeah, other than magnesuim match, real wire sparklers, safety fuse. I haven't looked into Class D stuff
[11:58:13] <Jymmm> Teh 'exotics' as I like to call them
[11:58:16] <Jymmm> The
[11:58:24] <IchGuckLive> question there are steppers with second axis for a encoder can you make a servo out of a 8wire stepper ?
[11:58:52] <jdh> Ich: yes, but it won't do anything useful (other than trapping following errors)
[11:59:29] <IchGuckLive> ok
[12:00:01] <IchGuckLive> so no nned to get the extra 1euro on that and loose 2cm of mashining way
[12:00:12] <Jymmm> jdh: Two things I've wanted to play with.... exotheric and Spontaneous combustion
[12:00:50] <jdh> we use lots of zirconium at work, it burns nicely
[12:00:50] <Jymmm> jdh: But, I need to go out to Black Rock to be safe =)
[12:00:59] <jdh> or, explosively in the right conditions
[12:01:20] <IchGuckLive> Titanium is best for fire miling
[12:01:36] <jdh> Ich: I'm sure there is an application where it might be useful, but not for this type of app.
[12:01:48] <IchGuckLive> with insert milling head it burns and bunrns
[12:04:34] <Jymmm> I've only once seen spontanous combustion... as a kid lived behind a place that sold rock, bark, sawdust, etc. They wet it down for dust control, I guess it was just a perfect warm day as the pile of chips went up.
[12:05:52] <Jymmm> Since then, I've always be interested in it.
[12:06:07] <Jymmm> been
[12:11:42] <Jymmm> jdh: Some layman explanations =)

[12:50:05] <r00t4rd3d> " I used 0.5" thick MDF, with the center polygon pocketed to a depth of 5/32".
[12:50:46] <r00t4rd3d> cutting out the clamps i can do, setting that pocket to be cut out, I cant do
[12:51:25] <r00t4rd3d> im getting sketckup pro, maybe i can do it with that
[12:51:26] <jdh> how 'tall' are the clamps?
[12:51:45] <r00t4rd3d> not sure exactly, couple inches
[12:51:57] <jdh> so, what's teh 5/32"?
[12:52:10] <jdh> wide?
[12:52:22] <r00t4rd3d> http://www.thingiverse.com/image:3406
[12:52:31] <r00t4rd3d> the pocket is where the bolt goes
[12:52:33] <jdh> oh, they are paired... nevermind.
[12:52:43] <jdh> gotcha
[12:53:11] <IchGuckLive> r00t4rd3d: why not a full clamp set for 30USD
[12:53:32] <r00t4rd3d> im trying to make stuff
[12:53:33] <jdh> click on the polygon, click 'pocket', set it for 5/32" deep, save gcode, run.
[12:53:46] <r00t4rd3d> jdh, in what app?
[12:53:57] <jdh> I use cut2d for that, but I paid for it.
[12:54:18] <r00t4rd3d> run it threw for me
[12:55:15] <IchGuckLive> wh not heekscad
[12:55:21] <jdh> what size end mill... what depth of cut, what stepover?
[12:57:02] <nlkdavid> in sketchup, google Intersect Faces tutorial, thats how to create pockets in something with unusual edges
[12:59:14] <r00t4rd3d> i found cut2d for free :D
[12:59:38] <nlkdavid> where?
[12:59:46] <r00t4rd3d> google
[13:00:04] <r00t4rd3d> http://www.demonoid.me/files/details/2669583/003021219885/
[13:02:59] <r00t4rd3d> heh
[13:03:04] <r00t4rd3d> works too
[13:05:19] <nlkdavid> what verson of cut2d u running?
[13:12:38] <nlkdavid> nevermind
[13:15:07] <jdh> I have 1.5
[13:16:03] <r00t4rd3d> i save it and the file extension is m
[13:16:12] <r00t4rd3d> is that right, looks like gcode inside
[13:16:56] <r00t4rd3d> nvm
[13:17:26] <davef> #join emc
[13:17:39] <davef> helo...
[13:17:50] <IchGuckLive> B)
[13:18:03] <IchGuckLive> now we are called linuxcnc ?
[13:18:03] <nlkdavid> howdy
[13:19:21] <davef> is this now emc channel?
[13:19:42] <nlkdavid> emc is linuxcnc
[13:19:58] <r00t4rd3d> it was renamed
[13:20:05] <IchGuckLive> the channel for G-code miling
[13:20:12] <davef> ok. haven't been here for quite a while thanks.
[13:20:26] <archivist> we are nothing to do with a strage company gorilla who forced a name change
[13:20:33] <archivist> storage
[13:20:41] <IchGuckLive> davef: can we help you out
[13:20:47] <archivist> see topic
[13:21:23] <davef> I was trying to find a download of cam expert. seems to have disappeared from the web. any help?
[13:22:31] <davef> What I really want is something I can use on my windows laptop to set the cutting order of output from qcad3.
[13:23:41] <davef> I have a _lot_ of arcs to handle or i would just edit it by hand.
[13:23:49] <IchGuckLive> davef: mach4
[13:24:06] <archivist> er what
[13:24:12] <IchGuckLive> or there is also heekscadCAM for windows
[13:24:37] <davef> cost of mach4 or heekscadCam?
[13:25:44] <IchGuckLive> heeks is opensource
[13:26:16] <IchGuckLive> http://code.google.com/p/heekscnc/downloads/list
[13:26:33] <nlkdavid> heekscadCAM is free, never heard of mach4
[13:26:35] <IchGuckLive> http://code.google.com/p/heekscad/downloads/list
[13:26:56] <r00t4rd3d> jdh, in cut2d how do i save the toolpath to work with linuxcnc?
[13:27:04] <davef> thanks. i found it.
[13:31:33] <r00t4rd3d> jdh, post processor to use I guess is what i am asking
[13:32:01] <IchGuckLive> Fabus11 or 12
[13:32:10] <IchGuckLive> Fanuc
[13:32:37] <IchGuckLive> also standart iso
[13:33:29] <r00t4rd3d> so
[13:33:36] <r00t4rd3d> you named off 4
[13:40:29] <IchGuckLive> Fanuc if available is the best
[13:40:42] <IchGuckLive> and ¹1 fits iso Milling
[13:41:41] <IchGuckLive> ok by im ooff
[13:44:12] <Loetmichel> soo, that was my workday today... times 37... and tomorrow 48 more, than the first charge of 120 is done... (and still 380 to go) ... Thanks to henry ford :-( ->

[13:44:50] <JT-Shop> seems turning a ball end on the lathe requires careful tool selection
[13:51:00] <nlkdavid> protection from standard dust or something worse?
[13:52:49] <nlkdavid> Loet
[14:01:49] <Loetmichel> nlkdavid: emi shielded systems, sealed after measurement, so no pessured air for dedusting-> externel air filter to prevent dust entering the case
[14:15:57] <archivist> JT-Shop, a tube ground flat and hardened, used hand held
[14:17:25] <JT-Shop> archivist: I'm doing it on my CHNC so I'm just complaining about having to make comprimises
[14:17:48] <archivist> :)
[14:19:12] <archivist> I made a sphere once in two parts, interesting
[14:26:39] <JT-Shop> the object in question
http://imagebin.org/221748
[14:29:22] <WillenCMD> anyone know how to flip the bit on a usb flash drive, to turn it into a mass storage device
[14:32:10] <archivist> JT-Shop, are you trying to get away with one tip
[14:32:17] <Loetmichel> JT-Shop: CNC or conventional lathe?
[14:32:19] <anonimas1> I turned a ball like that today also
[14:32:28] <JT-Shop> no, I'm using a couple
[14:32:57] <JT-Shop> one to do the top of the ball and down to the flat and a pointy one to do the inside cut
[14:33:23] <JT-Shop> Loetmichel: Hardinge CHNC
[14:33:24] <anonimas1> I used the pointy one to turn everything
[14:33:37] <JT-Shop> even the top of the ball
[14:33:42] <anonimas1> yeah
[14:33:48] <anonimas1> 35 deg finish insert
[14:34:00] <anonimas1> tho, not a full ball.
[14:34:01] <Loetmichel> JT-Shop: then you could get away with a small chisel witr a "circle" top
[14:34:06] <anonimas1> i changed the flank to get away with it
[14:34:09] <JT-Shop> LH holder
[14:34:20] <Loetmichel> small enough to fit in the radios at the bottom of the ball
[14:38:56] <JT-Shop> I do have this one
http://imagebin.org/221750
[14:48:37] <archivist> thats the type of insert I was thinking of for that
[14:53:10] <JT-Shop> I think I'll put that one in and give them a whirl
[15:03:18] <Tom_itx> JT-Shop I got the display working but i need to figure out the scale
[15:03:52] <Diony> hi
[15:03:57] <Tom_itx> i think the hostmot2 driver scales it to counts per second or revs per second
[15:04:56] <Tom_itx> Estimated encoder velocity in position units per second.
[15:05:03] <Tom_itx> is that ticks or revs?
[15:17:55] <Tom_itx> seems it's ticks
[15:32:02] <r00t-Shed> where are the feed rates in gcode?
[15:32:34] <Tom_itx> F
[15:32:40] <r00t-Shed> ahhh
[15:32:42] <r00t-Shed> i see
[15:32:43] <Tom_itx> yours are at the top
[15:32:53] <Tom_itx> F6 iirc
[15:33:15] <Tom_itx> i'd double that on wood at least
[15:34:37] <r00t-Shed> if i set them high they will just default to my machine settings right?
[15:34:39] <Tom_itx> your plunge was 12 i think or 12.5
[15:34:56] <Tom_itx> they will try to feed at the rate you enter
[15:35:09] <Tom_itx> within your max limits
[15:35:35] <Tom_itx> learn to figure them correctly
[15:35:37] <r00t-Shed> i got it moving now
[15:39:35] <r00t-Shed> whats the M in gcode at the top ?
[15:41:02] <Tom_itx> an m word
[15:41:43] <Tom_itx> http://www.linuxcnc.org/docs/html/gcode/m-code.html
[15:49:02] <r00t-Shed> i figured you would not just tell me
[15:50:13] <r00t-Shed> support chat, heres your link!
[15:57:26] <grogan> Hello all. I'm stuck (and been so for 3 weeks). I can not get signals from any pp pin except pin 1 (estop). I've tried two machines - Compaq Presario rs1010v w/ onboard parport and a Dell GX620 w/ onboard pp as well as with two pci pp cards (Siig and StarTech). I can provide lspci -v and .hal info. I've read and re-red the manuals, wiki and numerous Google search results. I'm desperate, please help. I've built the cnc (borrowed heav
[15:57:26] <grogan> ily from Tom McGuire - pardon spelling) and built driver boards that work like a charm with mock signals from an arduino mega. Help!
[15:58:21] <archivist> some parallel ports need pull ups
[15:58:57] <archivist> do you have a scope to check signal voltages
[15:59:33] <grogan> I did read that and am willing to give it another shot. Yes (kind of). I'm using xscope through soundcard.
[16:00:53] <DJ9DJ> gn8
[16:00:54] <grogan> I tried 1K, 10K and 100K, both pull up and pull down but that was a while back. recommendation on first resistor value?
[16:01:02] <archivist> I have never used those soundcard things, I prefer the real thing TM
[16:01:23] <archivist> nearer 1k
[16:02:00] <grogan> I do need to pick one up. Thanks for the 1K suggestion, I'll give it a try and report back in a few minutes.
[16:03:19] <Tom_itx> open collector outputs require pullups generally
[16:19:43] <archivist> just found a book that was missing in action for a number of years Precision measurement in the metal working industry, its by IBM from 1952 when they were making mechanical stuff still
[16:27:56] <alex4nder> sup
[16:35:13] <grogan> Archivist, if you are still out there this is what I found. Scenario 1 - w/ the dvm between 25 and 1, 1 reads 4.27V with estop in and 1.02 with it out. Scenario 2 - w/ the dvm still between 25 and 1, pull up on 1 to +5V and the pin 25 connected to power supply ground, whether estop is in or out, pin 1 remains at +5V. Thoughts?
[16:38:50] <grogan> BTW, no driver circuit is connected at the time. All signal are read directly from the parallel port connected to a breadboard. Interestingly, w/o the pull up, the pp responded as expected. w/ the pull up pin 1 remained at a solid 5V.
[16:44:21] <WillenCMD> anybody know what is the best option for a portable operating system, so i can work on ubuntu at home, put a usb stick in at work on windows 7 and run it from in windows 7? i have googled some but they don't seem to be cross platform
[16:58:40] <Connor> Okay, so, how do people setup auto tool changers?
[17:15:40] <grogan> Anyone had any success in reading signals directly from the parallel port to confirm, for example estop, xdir, ydir, etc. are working properly?
[18:14:20] <tjb1> Im wondering if all this penn state crap is going to make my degree worthless
[18:17:17] <jdh> you are at penn state? you perv.
[18:17:26] <tjb1> No im not at penn state
[18:18:22] <jdh> are you a catholic priest?
[18:22:08] <tjb1> no...
[18:22:44] <tjb1> i go to a school affiliated with penn state
[18:23:55] <Tom_itx> you should drop out and become a hippie
[18:23:59] <jdh> so, you are just a garden variety perv.
[18:27:52] <gmagno> hey, about that sleep mode in driver boards (for instance, A4984 from pololu). SHould the board be in non sleep mode to drive the motors? Does it also operate in sleep mode? What are the differences? The datasheet lacks in detaisl...
http://codepad.org/X0QFuNeN
[18:35:20] <gmagno> ok, I think it really stops working in sleep mode
[18:35:44] <Tom_itx> shut that off
[18:36:00] <davidf> hey
[18:37:12] <davidf> anybody know what happened to cam expert software? It seems to have disappeared from the web. Can't find any downloads
[18:41:11] <Tom_itx> guess you'll never know
[18:45:45] <Tom_itx> anybody ever run across / use this place:
http://www.qtcgears.com/
[18:52:34] <jdh> that sleep mode sounds too sleepy.
[18:57:15] <tjb1> Doesnt anyone sell standard/imperial gear rack besides moore gear....
[18:57:19] <tjb1> or mcmaster
[19:05:23] <Tom_itx> stock drive products and the one i just linked above
[19:06:28] <tjb1> Where is the standard racks at on qtc?
[19:07:11] <Tom_itx> probably under the 'RACK' menu item
[19:07:59] <tjb1> Really?
[19:08:19] <tjb1> Its all metric.
[19:08:39] <Tom_itx> so i see. i just ran across them tonight
[19:08:47] <Tom_itx> stock drive probably do
[19:09:15] <Tom_itx> http://www.sdp-si.com/
[19:09:23] <tjb1> The only 20 pitch they have is $80 for 11"
[19:09:31] <tjb1> I dont need a stainless steel rack
[19:09:34] <tjb1> :)
[19:09:44] <Tom_itx> who? stp?
[19:09:59] <tjb1> Yes
[19:10:29] <Tom_itx> what's it for?
[19:10:36] <tjb1> The plasma table drive
[19:10:44] <Tom_itx> maybe you should look at that belt drive that andy posted the other day
[19:10:49] <Tom_itx> 2 interlocking belts
[19:10:49] <tjb1> I dont remember but I think moore gear wanted $240 shipped for 5- 6' pieces
[19:11:02] <Tom_itx> it looked like the shizzle
[19:11:12] <tjb1> You have the link?
[19:11:14] <Tom_itx> seriously you should ask him
[19:11:16] <Tom_itx> no
[19:11:46] <tjb1> Ill try to remember
[19:11:50] <Tom_itx> the belt layed flat across the side and was driven by an interlocking belt
[19:12:01] <Tom_itx> it looked pretty cool
[19:12:12] <Tom_itx> gotta be cheaper than ground rack
[19:12:30] <tjb1> I dont need ground
[19:13:14] <tjb1> But it is looking like moore gear is the best
[19:13:29] <tjb1> I called a boston gear supplier and they wanted like $120 for a 6' piece
[19:14:07] <tjb1> I would make it myself but the school doesnt really have anything big enough to do a sizable piece on
[19:19:46] <Tom_itx> JT-Shop you around?
[19:25:15] <Tom_itx> http://bell-everman.com/products/linear-positioning/servobelt-linear-sbl
[19:25:18] <Tom_itx> and he left
[20:07:00] <gmagno> erm... what's the relation between the reference voltage and the sense resistor in a stepper motor driver?
[20:07:12] <gmagno> how should I set that ref voltage?
[20:07:56] <gmagno> imagine, for a 0.05ohm resistor and a max ref voltage of 5V
[20:07:58] <Tom_itx> the data sheet should give you some indication
[20:08:16] <gmagno> I'm digging a lot
[20:08:19] <gmagno> really
[20:08:37] <gmagno> in the datasheet as well
[20:08:53] <Tom_itx> i don't have a better answer
[20:09:15] <jdh> a .05ohm resistor?
[20:09:25] <gmagno> jdh, yes
[20:10:06] <gmagno> that's the sense resistor used in those pololu drivers (A4988)
[20:10:28] <gmagno> the thing is, I don't want to burn anything, so I'm a bit worried about the ref voltage
[20:11:26] <gmagno> they say I should tune this ref voltage in order to get the right current to the motors
[20:12:04] <jdh> With Pololus, the sensing resistors are Rs=0.05 ohm, so a Vref of 0.4 should produce a maximum current of 0.4/(8*0.05)=1A
[20:12:40] <gmagno> jdh, why 8 times?
[20:13:17] <jdh> Per the A4988 datasheet [[1]], the calculation for the maximum trip current is: I_TripMax= Vref/(8*Rs)
[20:14:11] <gmagno> would it be too much abuse to ask which page?
[20:14:27] <jdh> page 9, middle left column
[20:14:32] <gmagno> =D
[20:15:22] <jdh> or, lmgtfy.
[20:15:29] <gmagno> jdh, thank you a lot, really
[20:15:35] <gmagno> no thanks :)
[20:16:01] <jdh> <- mad g00gl3 sk11lz
[20:18:10] <gmagno> :)
[20:21:10] <jdh> I got that from the first hit for "pololu drivers (A4988) sense resistor"
[20:21:51] <gmagno> damn you're good
[20:21:52] <gmagno> :)
[20:22:07] <jdh> and I just won this!
http://www.ebay.com/itm/190702461301
[20:23:01] <gmagno> no way!
[20:23:05] <Tom_itx> winning indicates you got something for free
[20:23:45] <gmagno> Tom_itx, has point in that
[20:23:47] <jdh> I just wanted the motor. I can resell the other parts for more than the bid price.
[20:23:47] <gmagno> :)
[20:24:00] <Tom_itx> 12v?
[20:24:02] <Tom_itx> 24v?
[20:24:11] <jdh> 24vdc, 16amp
[20:24:18] <Tom_itx> nice
[20:25:09] <jdh> with full load anyway. It's a really nice motor for the application.
[20:26:34] <r00t4rd3d> what are you going to do with the motor?
[20:26:49] <jdh> I have a dead one in another scooter
[20:29:58] <ReadError> r00t4rd3d, wheres the joker foo
[20:30:12] <jdh> did you get the clamps CAMed?
[20:30:13] <Connor> jdh What's the application?
[20:30:29] <jdh> connor: underwater scooter
[20:30:34] <Connor> Ah.
[20:31:34] <jdh> I have my 'real' one and parts for three others I've been accumulating. Those parts give me enough to rebuild all three.
[20:41:42] <r00t4rd3d> ReadError, it didnt turn out too well
[20:41:53] <r00t4rd3d> i used the wrong bit to rough it in
[21:29:40] <r00t4rd3d> ReadError, I have a new joker I am going to try though :
[21:29:43] <r00t4rd3d> http://i.imgur.com/Xw0XX.jpg
[21:30:35] <Tom_itx> ever try one in acrylic?
[21:30:54] <Tom_itx> run a strip of leds along the edge
[21:36:17] <gmagno> I'm sad... :-/ I'm trying to drive one of my stepper motors (NEMA17) with an A4984 pololu driver, but no success :-(( I've already done wiring check, conductivity tests with ohmmeter... what would you guys suggest? You know, something like a step by step procedure
[21:37:15] <jdh> power it up and try manually stepping it?
[21:37:16] <Valen> seen if the driver is putting anything out?
[21:37:30] <jdh> do the motors lock in when you power it?
[21:37:53] <gmagno> i'm gonna try the lock thing, seems easy to test
[21:39:16] <gmagno> jdh by lock you mean hard to rotate or really stuck?
[21:39:23] <jdh> really stuck
[21:39:34] <jdh> unless it is really low power
[21:40:12] <Valen> spin it before
[21:40:14] <Valen> apply power
[21:40:17] <Valen> then try and spin it
[21:40:24] <gmagno> this is a NEMA 17 1.68A max, and I configured Vref to 0.4V which means 1A max
[21:40:34] <gmagno> I've done that, it rotates
[21:40:39] <gmagno> it is hard to rotate
[21:40:54] <gmagno> hard like if you shunt one of the coils manually
[21:40:57] <Valen> is it harder than with no power?
[21:41:02] <gmagno> not really
[21:41:04] <Valen> it should go clunk clunk
[21:41:13] <Valen> your driver isn't putting any power out would be my guess
[21:41:15] <jdh> do they get warm at all when powered on?
[21:41:21] <gmagno> what is clunk clunk?
[21:41:25] <jdh> cogging
[21:41:26] <Valen> put a multimeter on the output you should see voltage
[21:41:32] <gmagno> jdh it gets hot
[21:41:52] <Valen> if you have applied power and try to turn it it should be quite hard to turn and jump between steps
[21:41:56] <gmagno> Valen, what output? motor coil=
[21:41:57] <gmagno> ?
[21:42:18] <Valen> the driver to the motor
[21:44:49] <gmagno> 0V :-(((
[21:45:00] <jdh> then how are they hot?
[21:45:35] <gmagno> jdh, the driver is hot
[21:45:50] <gmagno> not the motors
[21:45:59] <gmagno> the motor, I'm just driving one
[21:45:59] <jdh> oh. Are you sure the motor phases are hooked up correctly?
[21:46:20] <gmagno> jdh, checking again
[21:48:02] <gmagno> I'm sure they are well connected
[21:48:09] <gmagno> I mean the pairs
[21:48:19] <gmagno> the coils have no polarity
[21:48:21] <gmagno> right?
[21:48:26] <jdh> right, but they are paired
[21:48:35] <gmagno> sure
[21:51:34] <Valen> shouldn't get hot if its not driving anything
[21:51:43] <Valen> sure you have the power supply polarity correct?
[21:52:26] <gmagno> sure, look at this mess:
http://bambuser.com/v/2849218
[21:53:36] <gmagno> :-(
[21:53:44] <gmagno> polarity is correct
[21:54:45] <Tom_itx> you know, breadboarding isn't the best
[21:54:56] <Tom_itx> lots of times you get loose connections on the board
[21:55:11] <jdh> and shitty jumper wires
[21:55:16] <Tom_itx> make sure that's not the case
[21:55:38] <Tom_itx> more times than not that has been a problem
[21:56:18] <Valen> disconnect everything
[21:56:42] <Valen> connect the step/dir pins to power or ground or whatever they are sposed to be
[21:56:49] <Valen> look at the outputs
[21:56:54] <Valen> (with no motor connected)
[21:57:10] <gmagno> Valen, can I do that?
[21:57:20] <Valen> do what?
[21:57:36] <gmagno> drive open pin
[21:57:50] <gmagno> i mean, "drive"
[21:57:59] <gmagno> ok
[21:58:01] <gmagno> gonna try that
[21:58:08] <Valen> yeah that should be fine
[21:58:13] <Valen> inputs you cant let floar
[21:58:16] <Valen> float
[22:04:31] <gmagno> Valen, sorry for asking again, but this is what I have currently wired:
http://www.ebay.com/itm/280877891763?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649 including enable is grounded, reset and sleep to VDD. SHould I disconnect the motors and check the driver (motors) outputs?
[22:05:11] <Valen> i dont know the details of your specific board
[22:05:20] <Valen> I'm just saying how you can work out whats going on
[22:05:28] <Valen> break the problem down into individual steps
[22:05:43] <Valen> you can test the motor with a AA battery across a coil
[22:05:58] <Valen> but don't have it connected to the driver at the time obviously lol
[22:06:32] <gmagno> :) im not that dumb
[22:07:48] <gmagno> im doinbg it
[22:10:04] <gmagno> yup it's working
[22:10:09] <Valen> what is?
[22:10:20] <gmagno> the motor with battery
[22:10:24] <gmagno> AA battery
[22:10:31] <gmagno> motor should be fine
[22:10:38] <Valen> you can feel the "lumpy" nature of it?
[22:10:59] <gmagno> er... I can see the shaft moving a tiny bit
[22:11:21] <Valen> try and spin the shaft
[22:12:57] <gmagno> yeah
[22:13:02] <gmagno> it's really really stuck
[22:13:16] <gmagno> no way i can move it
[22:13:28] <Valen> thats good
[22:13:32] <Valen> thats how its sposed to be
[22:13:45] <Valen> if you did push hard enough you would spin it ;->
[22:13:53] <Valen> but don't bother trying lol
[22:14:19] <gmagno> I'm a 2,00m tall guy, I could not move it... :P
[22:14:25] <gmagno> lol
[22:15:04] <Valen> I'm 5'10" I legpress 320kg, ;-P
[22:15:30] <gmagno> :D
[22:16:18] <gmagno> ok, motor is in good conditions. Should I leave it disconnected from the driver for now?
[22:16:26] <Valen> yeah
[22:16:41] <Valen> you were using a battery for that test yes?
[22:16:55] <gmagno> yup, two 1.2 AA in series
[22:17:15] <Valen> ahh that explains it
[22:17:24] <Valen> using just 1 you could probably spin it
[22:18:00] <gmagno> wait, the test you mention is this test I've done now to check if the motor is working
[22:18:08] <Valen> yeah
[22:18:11] <gmagno> ah ok
[22:18:12] <gmagno> :)
[22:19:03] <gmagno> im just 100Kg, I need the other 100Kg for the second battery :P
[22:19:42] <gmagno> I would need*
[22:19:58] <gmagno> ok, what do you suggest now?
[22:19:59] <Valen> it'll go up with a ^2 power
[22:20:16] <Valen> is 2 batteries will be 4 or more times harder than 1
[22:20:25] <Valen> check out the driver
[22:20:26] <gmagno> yay :D
[22:20:45] <Valen> hook it up in a way that it should have an output
[22:20:51] <Valen> see if it meets your expectations
[22:21:11] <gmagno> ok
[22:24:16] <gmagno> nothing in the output... this board needs two power supplys, one is for logic voltages, and im using the arduino 5V, and the other, motors power supply, Im using 12V (enough amps don't know exacly how much)
[22:24:27] <gmagno> with the 5V power supply
[22:24:31] <Tom_itx> are there enable pins on it?
[22:24:43] <gmagno> there is
[22:24:52] <gmagno> it's a negative enable
[22:24:55] <gmagno> I put it to ground
[22:25:13] <Valen> how are you measuring the outputs?
[22:25:25] <gmagno> voltmeter
[22:25:30] <Valen> from what to what
[22:25:50] <gmagno> ah :-o
[22:25:55] <gmagno> arduino gnd
[22:25:59] <gmagno> that's the problem
[22:26:02] <gmagno> right?
[22:26:18] <Valen> wouldn't help
[22:26:25] <gmagno> thought both gnds were connected
[22:26:28] <Valen> measure from one output to the other
[22:26:30] <Valen> they may be
[22:26:32] <Valen> may not
[22:26:36] <gmagno> hmm ok
[22:26:39] <Valen> so measure from /A to A
[22:26:44] <gmagno> ok
[22:26:52] <Valen> do the same for b as well
[22:28:47] <gmagno> nothing
[22:28:48] <gmagno> 0.0
[22:28:52] <gmagno> in both
[22:28:59] <Valen> well theres what you need to debug
[22:29:06] <Valen> read the datasheet and see what it says
[22:30:18] <Valen> by the same token reading 0.0 for output means it shouldn't be getting warm
[22:31:38] <gmagno> dont tell me the boards are burnt... :-/ they cost me about 35€, three of them
[22:32:22] <Valen> is it still warm with the motor disconnected
[22:32:55] <Valen> its not something like your grounds are fighting through it or some other such sillyness?
[22:33:11] <gmagno> yup, temp runs high quickly
[22:33:30] <Valen> how hot does it get?
[22:33:41] <Valen> is it just warm like 40C or is it hot?
[22:34:15] <gmagno> this is burning hot like you can't stand it
[22:35:08] <gmagno> should I remaind you I'm a 2meter high dude with 100Kg... ehehe
[22:35:22] <gmagno> remind*
[22:35:42] <Tom_itx> not lookin so good
[22:36:32] <gmagno> could it be somehow related to the potentiometer connected to the Vref that sets the max current?
[22:37:25] <Valen> it shoudn't get that hot
[22:37:29] <Valen> ever
[22:37:54] <gmagno> fuc***
[22:38:04] <gmagno> i can see some black components
[22:38:12] <gmagno> wait
[22:38:16] <Valen> they are often meant to be black
[22:38:18] <gmagno> it was a shadow
[22:38:20] <gmagno> :D
[22:38:44] <Valen> you need to go through very very carefully and check the pinouts of everything
[22:38:52] <Valen> make sure nothing is shorted
[22:38:59] <Valen> you havent got the thing in backwards
[22:40:35] <gmagno> Valen, those are good advices and I really appreciate all the help. And I have no courage to ask for more help (at least for today...)
[22:40:45] <gmagno> thank you very much
[22:40:53] <Valen> 's ok
[22:40:54] <gmagno> i'll give more feednback
[22:40:55] <Valen> beats working
[22:41:07] <Valen> or more correctly raging at idiots
[22:41:09] <Tom_itx> har har
[22:41:48] <gmagno> :)
[22:43:50] <gmagno> 4:32AM here, I should get some sleep. Bye
[23:05:56] <uw> ugh
