[00:00:50] <dmess> 14 Million dollars worth of semi finished parts spread out over all of north america.... BTW we want you " to finish them off"
[00:01:30] <Alex9> :)
[00:02:53] <Alex9> i guess the answer: yes, we all going to do it
[00:03:08] <Alex9> help other
[00:03:14] <Alex9> another
[00:03:16] <dmess> no... this is another pile a crap i gotta sort thru and soil myself on when i really had 0% to do with the parts..
[00:03:53] <Alex9> :)
[00:04:18] <dmess> company is bancrupt.. parts are at processing houses
[00:05:24] <dmess> we've been trying to get tooling for a yr now... but it will be accellerated now that its MY baby
[00:05:29] <Alex9> bancrupt is the only word dictionary exist in my contry only not on west
[00:05:36] <Alex9> :)
[00:06:10] <dmess> many here in Kanada
[00:07:38] <Alex9> Kanada is a heaven, its west
[00:07:58] <Alex9> all u can find is there
[00:09:06] <Alex9> in my country, if we see 'made in west = the best' when it a low price, people will put aline
[00:10:29] <Alex9> a crane made in china 4ton mean 2.5ton ,germany 4ton mean 6ton
[00:10:46] <Alex9> even 7ton
[00:11:03] <Alex9> usa, no different
[00:13:49] <Alex9> even me would like to receive metal junk from your kanada.
[00:15:19] <Alex9> in my country a car build in 1970 still work fine on the streets, they called bajaj
[00:16:13] <Alex9> ColtT
[00:16:26] <Alex9> truck
[00:16:43] <Alex9> cos new one are expensive
[00:16:58] <Alex9> hahaha
[00:17:56] <Alex9> old truck: 11.000.000 , new one:200.000.000
[00:19:06] <Alex9> so, be opimistic
[00:19:15] <Alex9> :) god would help
[00:21:05] <Alex9> export it?
[00:26:38] <Alex9> Q. HOW TO MAKE TTK LAUGH ON SUNDAY?
[00:26:38] <Alex9> A. BY TELLING HER A JOKE ON THURSDAY.
[00:26:52] <Alex9> :)
[00:28:00] <Alex9> Girls are like roads, More the curves, More the dangerous they are.
[00:29:48] <Alex9> hi teapot
[00:30:05] <Alex9> how s the tea
[00:30:08] <Alex9> ?
[00:31:51] <Alex9> Love is only chatter, it's your friends that really matter.
[00:32:47] <Alex9> why in robotic japan are more advance?
[00:33:08] <spasticteapot> Hello.
[00:33:22] <spasticteapot> Alex9: Why can't you use proper grammar? :)
[00:33:31] <Alex9> nice to meet u teapot
[00:34:07] <Alex9> its a bad engilsh...my grammer not to good.
[00:35:39] <Alex9> how do u do today.... im in await downloading here. thats why im hanging
[00:35:47] <Alex9> :)
[00:37:20] <Alex9> have u ever know that EMC2 can run on FlashDisk ?
[00:40:24] <spasticteapot> Dunno.
[00:40:28] <spasticteapot> I'm useless at machining.
[00:41:45] <Alex9> whats your 1st interest
[00:43:54] <spasticteapot> DIY audio equipment.
[00:43:57] <spasticteapot> In this case, headphones.
[00:45:57] <Alex9> u might like to search the one with 'Pipe' on it, makes it more focus to inner ear
[00:46:34] <spasticteapot> ?
[00:47:20] <Alex9> like a sphere
[00:47:55] <Alex9> ...but, why ure in this CNC channel
[00:47:56] <Alex9> ?
[00:48:21] <spasticteapot> Because people here know a lot about how to use lathes.
[00:48:25] <spasticteapot> I, on the other hand, do not.
[00:48:40] <Alex9> i see
[00:49:12] <Alex9> what would u need a lathe for?
[00:49:41] <Alex9> how big would u in need
[00:51:42] <spasticteapot> I'm cutting bits of metal to make headphones.
[00:56:32] <Alex9> u should buy little one
[00:57:00] <Alex9> kind of on japan toy tamiya one
[00:58:23] <Alex9> time up, thanks to all of u
[02:19:16] <cradek> hmm, you can't pause g95 moves
[02:21:15] <jmkasunich> g95 = feed/rev, right?
[02:21:27] <jmkasunich> do they share code with the unpausable G33?
[02:23:58] <cradek> yes
[02:26:42] <jepler> sounds like they share a little too much code
[02:26:49] <jepler> * jepler <-- probably at fault
[02:30:13] <cradek> diameter .198 is a little too big, .197 is a little too small...
[02:31:19] <jmkasunich> don't want setscrews?
[02:32:40] <cradek> not really - it's a plastic shaft
[02:33:03] <cradek> I can hit .1975 easy enough - it'll be fine as long as they don't vary too much
[02:33:26] <cradek> they - the encoders
[03:44:15] <joe__> joe__ is now known as spasticteapot
[03:52:27] <Jymmmmm> SWPLinux: you on the road?
[03:52:44] <SWPLinux> yes
[04:25:48] <Jymmmmm> SWPLinux: Ah, do you just have a hotel fetish by chance?
[04:26:38] <toastydeath> i took an online iq test and got a 98
[04:26:45] <toastydeath> i'm sorry guys, i just didn't know i was retarded
[04:27:16] <Jymmmmm> toastydeath: You didn't know you were retards cause you are so retarded, ya retard!
[04:27:24] <toastydeath> CLEARLY
[04:27:30] <Jymmmmm> =)
[04:27:50] <toastydeath> this changes everything.
[04:28:13] <Jymmmmm> toastydeath: So, I guess this means your a savant (sp)
[04:29:05] <toastydeath> or it means I'm retarded!
[04:29:18] <toastydeath> well what really happened is i can't do simple math in my head
[04:29:41] <toastydeath> i can do differentiation pretty fast, but stuff like "wat iz 19 + 6 + 21"
[04:29:45] <toastydeath> i can't do, period
[04:30:46] <toastydeath> and they asked a lot of that.
[04:32:57] <Jymmmmm> toastydeath: QUICK! Factor 3107418240490043721350750035888567930037346022842727545720161948823206440518081504556346829671723286782437916272838033415471073108501919548529007337724822783525742386454014691736602477652346609
[04:36:06] <toastydeath> sry, maxima crashed
[04:36:07] <toastydeath> can't do it
[04:37:22] <Jymmmmm> The computation took 5 months on 80 2.2 GHz AMD Opteron CPUs.
[04:38:40] <toastydeath> hahaha
[04:38:42] <toastydeath> incredible
[04:39:03] <toastydeath> why, is it prime?
[04:39:07] <Jymmmmm> yes
[04:39:11] <toastydeath> hahaha
[04:39:25] <Jymmmmm> RSA Challenge, was worth $20K
[04:39:37] <Jymmmmm> err $30K
[04:41:12] <toastydeath> unfortunately 30k doesn't cover the cost of 80 opterons
[04:41:29] <Jymmmmm> doesnt' cover the electric bill either
[04:44:29] <fenn> a test with math questions is not an IQ test
[04:52:24] <toastydeath> fenn: i dunno anything about iq tests, i just googled "online iq test" hit "i'm feeling lucky"
[04:52:36] <toastydeath> i know it's not legitimate.
[05:42:39] <fenn> for anyone who hates cadsoft Eagle: http://www.liquidpcb.org/
[05:45:56] <Jymmmmm> bookmarked =)
[06:04:10] <tomp> liquid pcb is interesting, dloading now. but its opengl again.
[06:04:11] <tomp> would emc have fewer timing problems without X and OpenGL ?
[06:09:03] <tomp> hmm, i tell a lie, i cant find any src or bin to dload at sf. maybe only svn.
[09:02:35] <anonimasu> hm
[09:03:03] <anonimasu> anyone know how to make 3.14mm holes into something :/
[09:04:02] <anonimasu> well, 3.14mm interference fit..
[09:05:02] <archivist> er drill, and ream (or clockmakers bodge use a tapered reamer to size) eld make a D bit, or drill small and bore
[09:05:54] <archivist> thats sizes I work to but accuracy depends on needs
[09:19:44] <archivist> interference is fun as the tables dont go down that far
[09:21:59] <archivist> I do press fits on small gears around that size, I try to arrange some cutting if I can, also add a taper lead to make sure I'm in the hole
[09:54:30] <anonimasu> homeground HSS?
[09:55:15] <archivist> for boring yes hand grind small bits for the lathe
[09:55:38] <archivist> fun boring 2mm
[09:55:39] <anonimasu> maybe I could adjust a 3.5mm drill.
[09:56:16] <archivist> adjust a small to drill large , make one land longer
[09:56:44] <fenn> why do you need a 3.14mm hole?
[09:57:02] <anonimasu> because I need to mount a tacho to a motor..
[09:57:07] <fenn> is that for a 1/8" dowel?
[09:57:23] <anonimasu> and interference fit, is much more fun then trying to drill 1mm holes and tap them
[09:57:23] <anonimasu> :p
[09:57:53] <anonimasu> I'm thinking heating a aluminium coupler then pressing it into place
[09:58:13] <anonimasu> also, setscrews would add imbalance to the shaft..
[09:58:23] <archivist> just press no need to heat, ally will move out the way :)
[09:58:24] <fenn> superglue?
[09:58:43] <anonimasu> but I need 10 of them :)
[09:58:57] <anonimasu> archivist: well, if I press it on while it's warm..
[09:59:02] <anonimasu> archivist: it's damn sture never to let go
[09:59:05] <anonimasu> sure :p
[09:59:16] <archivist> I do all mine cold
[09:59:38] <anonimasu> hmm
[09:59:48] <archivist> and I do selection for best fit
[09:59:48] <anonimasu> well, that would work for me too..
[09:59:57] <anonimasu> selection?
[10:00:30] <archivist> make extra and select l best pairs for pressing together
[10:00:43] <anonimasu> ah
[10:01:20] <anonimasu> http://images.google.se/imgres?imgurl=http://www.rctech.net/forum/attachments/r-c-items-sale-trade/128139d1143436044-hudy-com-lathe-101400-sale-picture-199.jpg&imgrefurl=http://www.rctech.net/forum/r-c-items-sale-trade/107528-hudy-com-lathe-101400-sale.html&h=480&w=640&sz=65&hl=sv&start=2&um=1&usg=___bW3a6OnfYjJwWokA7ym5fXI8OI=&tbnid=tejQa48P4EILzM:&tbnh=103&tbnw=137&prev=/images%3Fq%3Dd%2Bbit%2B%252B%2Blathe%2Btool%26um%3D1%26hl%3Dsv%26safe%3Doff%26sa%3DG
[10:01:39] <anonimasu> pretty cool lathe
[10:03:52] <archivist> hmm strange little beast
[10:04:03] <anonimasu> archivist: the other option is to mount a micro boring bar into the mill vise and chuck the workpiece in the collet
[10:04:25] <anonimasu> and write a program to turn it..
[10:04:49] <archivist> I would use a collet on the lathe :)
[10:05:08] <anonimasu> well, I dont have a cnc lathe.. :p
[10:05:23] <archivist> nor do I at the moment
[10:05:54] <archivist> I can do some things faster without
[10:06:16] <anonimasu> well, my only concern is that I need a few of them
[10:06:17] <anonimasu> :)
[10:07:12] <anonimasu> turn it like a hat _| |_ set it up in the mill and do the secondary ops automated
[10:07:36] <archivist> I have quick release collet head lathe here and a quick change cross slide assy
[10:07:49] <anonimasu> I wish it was a bit smaller then I could press fit something a 3mm bushing
[10:07:53] <anonimasu> err something 3mm anway..
[10:08:07] <anonimasu> 3.14 is quite a bit to _force_ it to fit
[10:08:12] <archivist> make small press tooling to suit
[10:08:44] <archivist> I have a small arbour press
[10:08:53] <anonimasu> * anonimasu nods
[10:09:01] <anonimasu> we have one at work too
[10:09:49] <anonimasu> and a big hydraulic one :)
[10:11:58] <anonimasu> hmm..
[10:12:03] <anonimasu> maybe a d bit is what I need.
[10:13:39] <anonimasu> http://www.metalwebnews.com/
[10:39:07] <archivist> anonimasu, I assume from your turning in the mill comment that you saw the youtube of someones method like that (I was thinking of using the rotary as a tool changer to do similar)
[10:43:56] <archivist> this one http://nl.youtube.com/watch?v=wbfXXeiSHsw
[10:56:54] <alex_joni> heh, neat
[11:05:51] <anonimasu> oh.. I were thinking of using the spindle as chuck
[11:05:56] <anonimasu> and set up gang tooling in the vise
[11:07:44] <archivist> similar, I thought a plate with fittings to add to rotary
[11:10:37] <anonimasu> .)
[11:10:39] <anonimasu> :)
[11:10:54] <archivist> an irc wink!
[11:11:35] <anonimasu> haha
[11:11:55] <anonimasu> I think doing in the mill is easier then setting it up manually and taking lots of micro passes
[11:12:22] <anonimasu> micro(spring) boring bars are nontrivial :p
[11:12:24] <anonimasu> and trdious
[11:12:25] <anonimasu> tedious
[11:12:52] <archivist> how deep do you want to bore
[11:13:16] <anonimasu> ~6mm
[11:14:28] <archivist> I have gone that deep with my small tools (and not broken one yet)
[11:16:43] <archivist> thinking when I made the small bars, was about 6-7 years ago and still using
[11:17:40] <archivist> made from 1/8" square hss
[11:19:22] <archivist> to me the hard part is measuring the hole
[11:22:46] <anonimasu> *nods*
[11:23:12] <anonimasu> I'd turn a bar to 6.10 or something and check against
[11:24:51] <anonimasu> for that part
[11:25:55] <archivist> I also use sets of number/letter drills as guages
[11:26:12] <anonimasu> http://images.google.se/imgres?imgurl=http://www.ifanger.com/images/news/MTEN_40702.jpg&imgrefurl=http://www.ifanger.com/english/firma/detail.cfm%3FID%3D1A949FCE-55A2-491B-B1A4BFED15DF0D96&h=190&w=300&sz=15&hl=sv&start=24&um=1&usg=__cWpVW5pwkwywjZiOVhBFYiWfhxw=&tbnid=67SODpt4FqbpZM:&tbnh=73&tbnw=116&prev=/images%3Fq%3Dmicro%2Bboring%2Btools%26start%3D21%26ndsp%3D21%26um%3D1%26hl%3Dsv%26safe%3Doff%26sa%3DN
[11:26:20] <anonimasu> 0.7mm boring bars >p
[11:26:23] <anonimasu> :P
[11:26:56] <archivist> teeny
[11:27:14] <archivist> but dont ask the price
[11:27:47] <anonimasu> http://www.asitooling.com/images/facemill.jpg
[11:27:47] <anonimasu> wow
[11:28:39] <archivist> hmm failing to load here
[11:30:50] <archivist> I made a 3mm od 60 degree ish V mill tool to do a dovetail groove, just turned basic shape and dremel some cutting teeth on it
[11:31:03] <anonimasu> hm, I found a sink edm for 1000eur
[11:38:33] <anonimasu> ^_^
[11:41:45] <anonimasu> I wonder how this part will toolpath.
[11:42:46] <anonimasu> probably not well.
[12:04:29] <anonimasu> *7yawn*
[16:14:08] <anonimasu> hello
[16:14:23] <anonimasu> :)
[16:15:03] <toastatwork> hay
[16:15:21] <fragalot> *wave*
[16:15:27] <fragalot> MEXICAN wave!
[16:15:38] <toastatwork> que?
[16:15:45] <fragalot> Exactly.
[16:19:29] <anonimasu> what's up?
[16:19:30] <anonimasu> I
[16:19:37] <anonimasu> I've beeen making toolpaths for this part of mine
[16:22:59] <alex_joni> anonimasu: do you use alibre CAM ?
[16:23:13] <alex_joni> I saw they have a 2.5D version which is free
[16:23:25] <alex_joni> CAM Xpress goes together with Design Xpress..
[16:23:40] <alex_joni> I think it's invite only so far ;)
[16:26:47] <anonimasu> no I dont
[16:34:46] <archivist> alex_joni, has emc been compiled on a 2 core 64 bit AMD (tried compiling sim and it failed)
[16:37:14] <alex_joni> aryup
[16:37:19] <alex_joni> archivist: yup
[16:37:29] <alex_joni> there are even RT packages for amd64
[16:37:34] <alex_joni> for SMP :)
[16:38:14] <archivist> hmm odd probably some digging to do to see why the build fails
[16:39:22] <alex_joni> any errors?
[16:39:39] <alex_joni> is it CVS TRUNK?
[16:39:44] <archivist> loads
[16:39:50] <archivist> yes is trunk
[16:40:10] <alex_joni> can you paste one?
[16:40:20] <alex_joni> did ./configure report any issues?
[16:40:48] <archivist> seems related to TK
[16:41:09] <alex_joni> can you pastebin the output of ./configure ?
[16:41:22] <archivist> Compiling emc/usr_intf/emcsh.cc In file included from emc/usr_intf/emcsh.cc:23: /usr/include/tcl8.4/tk.h:23:3: error: #error Tk 8.4 must be compiled with tcl.h from Tcl 8.4 In file included from emc/usr_intf/emcsh.cc:23: /usr/include/tcl8.4/tk.h:322: error: ‘CONST84’ has not been declared

[16:48:36] <jepler> #
[16:48:49] <jepler> configure:5704: checking for tcl

[16:48:50] <jepler> configure:6334: result: /usr/lib/tk8.4/tkConfig.sh found
[16:49:26] <jepler> ^^^ your system apparently has development packages for tcl8.3 and tk8.4 installed. these need to have the same version, not different versions
[16:49:44] <alex_joni> configure:6013: result: /usr/lib/tcl8.3/tclConfig.sh found
[16:49:56] <alex_joni> heh, jepler was faster
[16:50:13] <jepler> remove tcl8.3-dev and add tcl8.4-dev
[16:50:21] <jepler> or whatever the package is called
[16:50:31] <alex_joni> what jepler said :)
[16:51:12] <jepler> if you have tcl8.3-dev and tcl8.4-dev installed and want to keep it that way, configure script improvements to detect this situation and do the right thing would be a nice addition -- and you're in a prime position to figure out whatever the fix is
[16:51:47] <archivist> I have both devs
[16:51:50] <jepler> you could also try --with-tclConfig= and --with-tkConfig= to override the ones automatically found by configure
[16:52:17] <archivist> hmm never fsckd with configure before....
[16:53:13] <alex_joni> ./configure --help
[16:54:12] <alex_joni> hmm.. they launched portability over here for mobile networks
[16:54:33] <alex_joni> since 1-2 days ago, you can change networks at will and keep the phone number
[16:57:45] <jepler> you could try this patch, which should at least detect the version mismatch at configure time instead of during compilation: http://emergent.unpy.net/files/sandbox/configure-detect-tcl-version-mismatch.patch
[16:58:29] <fragalot> aah hot hot hot
[16:58:37] <fragalot> * fragalot burned his tongue
[16:59:04] <archivist> i just uninstalled 8.3 redid ./configure make and only one worning
[16:59:32] <alex_joni> jepler: might have forgotten this in there:
[16:59:33] <alex_joni> +TCL_VERSION=8.3
[16:59:39] <archivist> hal/classicladder/spy_vars_gtk.c:382: warning: cast to pointer from integer of different size
[16:59:40] <jepler> oops, yeah, that was for testing!
[17:00:12] <alex_joni> I figured :)
[17:00:37] <alex_joni> archivist: seems safe to ignore that for now
[17:00:42] <jepler> archivist: I've never tested classicladder on 64-bit systems
[17:01:40] <archivist> I was just playing the other night when jepler was explaining to the noob how to build
[17:02:14] <archivist> and I want to play with trunk and the later gui's
[17:03:16] <archivist> this box has no ports to hardware yet
[17:03:30] <jepler> that code related to the warning looks a bit suspicious; I doubt classicladder has been thoroughly tested on 64-bit systems
[17:04:56] <archivist> I cant see me needing to play there yet
[17:04:59] <jepler> it looks like that code plays fast and loose with the idea that sizeof(int) == sizeof(long) == sizeof(void*)
[17:05:06] <jepler> a big no no for 64 bit systems
[17:05:22] <archivist> er yes
[17:09:46] <fragalot> :o
[17:13:46] <archivist> I do like strong types to stop that sort of code
[17:13:46] <fragalot> nobody discriminates 64bit systems and lives when i'm arround!
[17:17:21] <emcnewb> Hello, I'm new to IRC and I just want to ensure that I'm at least going in the right direction as far as getting information on EMC. -Question, is this a starting place for beginning emc?
[17:17:47] <archivist> yes
[17:18:00] <emcnewb> Thanks.
[17:18:15] <archivist> users and devs hang about
[17:18:53] <emcnewb> k, I'm definetly a user.
[17:18:54] <archivist> and those who one will get around to using emc one day
[17:21:13] <emcnewb> can you point me in a direction to get a mesa electronics 5i20 up and running on ubuntu? thus far I've gotten my home made minimill to run through the parallel port using emc2. (stepper motors) but my steps/rev is high, and my threading on the lead screws is 50tpi, so my feed rate is really slow. I'm hoping a 5i20 board can speed things up.
[17:23:15] <archivist> steppers have limiting step rates
[17:26:20] <emcnewb> ic, however my technical info states my motors can get up to around 1200 rpm, and currently they are at about 30. due to the latency limitation on the parallel port on my computer.
[17:27:11] <archivist> what supply are the steppers on
[17:27:21] <archivist> volts etc
[17:27:49] <archivist> and what drivers gecko?
[17:27:59] <emcnewb> Daedal
[17:28:23] <emcnewb> Daedal MS series drivers
[17:33:13] <emcnewb> I was just wondering if I could send step pulses through the Mesa 5i20 board instead of through the parallel port. Everything that I've read so far has indicated that this board is best used with a servo encoder PID system rather than open loop stepper motors.
[17:34:10] <archivist> yes servo is faster and there is feedback and full control
[17:35:12] <maddash> feedback is overrated
[17:35:26] <archivist> but with perhaps better settings you may get better performance from steppers
[17:35:40] <archivist> better than now
[17:36:16] <emcnewb> I'm currently using stepper motors and getting a max speed of about 30 rpm.
[17:36:41] <emcnewb> making my rapid movements about 0.5"/min
[17:36:49] <archivist> seems to slow, steppers undersized?
[17:37:07] <emcnewb> cant get fast enough pulses to the drivers throught the parallel port
[17:37:39] <emcnewb> I'm confident in the size of the steppers (this is a desktop mini-mill)
[17:37:49] <archivist> have you set a silly micro stepping number
[17:38:53] <archivist> I half step
[17:39:36] <emcnewb> the manual says my motors are 20,000 steps per rev
[17:39:55] <archivist> ah silly
[17:40:05] <archivist> I use 400 per rev
[17:41:19] <emcnewb> Aren't I limited by the motor type though?
[17:41:31] <emcnewb> i.e. the steps per rev for the motor?
[17:42:07] <fragalot> mine do 400, pretty default i think
[17:42:19] <archivist> motor will 99% be 1.8 deg 200 steps per rev
[17:42:38] <archivist> half step at 400
[17:42:43] <fragalot> right. mine do 200, but i halfstep
[17:42:49] <fragalot> *commonmistake*
[17:43:19] <emcnewb> I've successfully controlled a 1.8° per step motor, but these are different.
[17:43:39] <archivist> therefore emcnewb your drive is microstepping
[17:43:56] <emcnewb> ah, ic. duh *smack
[17:44:06] <emcnewb> ty. I'll try changing some settings.
[17:44:20] <archivist> yup see drive manual
[17:45:09] <archivist> * archivist couldnt find the manual on parkers site
[17:55:15] <emcnewb> it's a tough manual to find. However I did get my speed to go up by lowering the latency setting in the stepconf wizard. I discovered that if you put it too low it will freeze linux.
[18:02:53] <emcnewb> I found the manual at "http://www.parkermotion.com/manuals/c-cx/c_ug.pdf" Looks like on page 11 (first bullet) I just may need to change some jumpers?
[18:03:26] <alex_joni> whee... http://www.itac.ro/weblog/2008/10/16/wifi-security-is-not-anymore-secure/
[18:03:30] <archivist> dont quote a url
[18:03:34] <emcnewb> oops sorry
[18:03:54] <maddash> why not?
[18:04:25] <archivist> stopped my client from opening a window in firefox
[18:04:47] <emcnewb> real sorry.
[18:05:22] <emcnewb> general question about stepper motors then. Is micro stepping a function of the driver or the motor?
[18:05:29] <archivist> had to copy paste :)
[18:05:35] <archivist> driver
[18:06:11] <emcnewb> ah, this is starting to make sense.
[18:06:28] <archivist> emcnewb, but for best resonance/speed possibly halfstep, depends
[18:07:35] <alex_joni> emcnewb: there is an excellent paper about steppers around geckodrives.com
[18:07:46] <emcnewb> cool, ty.
[18:09:08] <emcnewb> says in the manual "Factory default resolution of 200 steper per revolution, with optional jumper-selectable setting of 25,000, 20,000, 18,000 10,000, 5,000, 2000, and 400 steps/rev"
[18:09:28] <alex_joni> ok, so halfstep is the minimum you can select
[18:09:55] <archivist> er no 200 steper per revolution
[18:09:55] <emcnewb> Do I have to tear into the driver and physicall change some jumpers?
[18:10:32] <archivist> page 4
[18:11:05] <emcnewb> Ah, ic.
[18:11:17] <archivist> have you set the correct current as well
[18:12:46] <emcnewb> I haven't made any current settings to be honest with you. This is an xy table given to me and I'm still trying to understand it. I assumed that all that was working correctly.
[18:14:10] <archivist> may have been set low to run cool, may be able to use more for faster movement and more torque
[18:15:08] <dmess> mine are set way too cool... in anything more tha 1/4 step it wouldnt burp the motor over even
[18:15:36] <dmess> seems ok at 1/8 step
[18:16:15] <anonimasu> hmm
[18:16:20] <anonimasu> ALWAYS SET CURRENT LIMITS!
[18:16:33] <alex_joni> when in doubt set them low ;)
[18:16:33] <archivist> I run at the limy :)
[18:16:42] <anonimasu> and in case you didnt hear me the first time SET CURRENT LIMITS
[18:16:44] <anonimasu> or else.
[18:16:45] <anonimasu> :)
[18:17:01] <archivist> I like a warm motor
[18:17:10] <anonimasu> oh.. I melted one before
[18:17:59] <archivist> melting is a little extreme, but they should be very happy to 80 deg C
[18:18:40] <archivist> I think my Z gets to the 50's
[18:19:38] <anonimasu> the driver blew up when that happened ^_^
[18:19:45] <emcnewb> doh
[18:19:51] <anonimasu> nice little mushroom cloud..
[18:20:06] <archivist> magic smoke got out
[18:31:21] <emcnewb> Thanks a ton archivist! You've helped get me going in the right direction
[18:31:33] <emcnewb> thanks all
[18:32:24] <archivist> faster now?
[18:34:04] <fragalot> oops
[18:34:21] <fragalot> speaking of current limits.. Haven't set mine yet on the Z........
[18:35:04] <archivist> amps and volts is the first !
[18:35:19] <anonimasu> :)
[18:35:35] <archivist> or smoke is faster
[18:36:04] <emcnewb> lol, motors are faster
[18:36:39] <emcnewb> I haven't gotten the motors to smoke yet, but the weekend is almost here.
[18:36:55] <archivist> careful with your gcode now as its a racing machine now
[18:37:37] <emcnewb> Next is to figure out the limit switches and the linear encoders.
[18:37:48] <anonimasu> well, set your limits up first :)
[18:39:02] <archivist> I had to re-engage my lead screw a few time because i was lazy setting limits
[18:39:12] <emcnewb> cya guys thanks again!
[18:39:33] <archivist> emcnewb, lurk in here if you wish
[18:39:54] <emcnewb> gotta leave, but I'll be lurking when i'm at/around the comp.
[19:18:07] <fragalot> * fragalot breaks a tile and hands it to archivist
[19:19:43] <archivist> why would I want a broken tile
[19:20:15] <archivist> is this some sort of Belgian local joke
[19:20:18] <fragalot> what? Is my gift to you not good enough?
[19:20:24] <fragalot> * fragalot feels offended
[19:20:28] <fragalot> gimme my tile back
[19:20:57] <archivist> * archivist grinds it to powder first
[19:21:01] <fragalot> archivist: i'm just bored, ... and you were the unlucky nick I saw first
[19:21:38] <archivist> Im waiting for bearings to make prototype trunnion
[19:21:53] <archivist> I should order seals
[19:22:01] <fragalot> whats a trunnion?
[19:23:01] <archivist> http://img.photobucket.com/albums/v280/rallyslag/16032008361.jpg
[19:23:50] <archivist> or this http://www.haas.co.uk/tr110.html
[19:24:12] <archivist> but commercial prices are silly
[19:24:22] <archivist> I want to make cheap ones
[19:24:51] <fragalot> ah yes
[19:24:59] <fragalot> good luck on that
[19:25:35] <archivist> I have design part worked out including the removal of all play
[19:27:21] <archivist> or this style http://www.haas.co.uk/tr160.html
[19:33:56] <anonimasu> archivist: why not just sealed bearings?
[19:34:21] <archivist> anonimasu, needs taper roller really
[19:34:31] <anonimasu> ah
[19:34:35] <archivist> they dont come sealed
[19:34:39] <anonimasu> I know
[19:34:56] <anonimasu> Yes, you need seals then
[19:35:04] <anonimasu> :/
[19:37:21] <archivist> will only use cheap ones but I think they will be good enough
[19:39:12] <anonimasu> * anonimasu nods
[19:46:30] <dmess> who knows of a decent spindle encoder for my hardinge...??
[19:50:03] <archivist> * archivist would swap an encoder for a hardinge
[19:52:57] <cradek> http://usdigital.com/products/encoders/incremental/rotary/shaft/s1/
[19:53:28] <cradek> hmmmm I wonder which one I have on my lathe spindle - if it is the sleeve bushing, I'm overdriving it "a bit" (2500 rpm, spec is 100 rpm)
[19:54:23] <archivist> hmm they look cheap and suitable
[19:55:12] <cradek> yeah I haven't had any problem, but differential outputs would definitely be better
[19:56:05] <cradek> there is a pulley run by a toothed belt going around the spindle. the pulley runs in bearings and is coupled to the encoder with a flex coupling
[19:57:45] <archivist> my mill spindle is a bit awkward to modify at the moment due to the end float adjusters
[19:59:03] <archivist> dunno what count to use for hobbing though
[20:33:44] <fragalot> http://chroniclesofgeorge.nanc.com/
[20:33:45] <fragalot> lmao
[20:45:19] <MASEngr> So, a quick question: Where's the "G Code Manual" referred to in the Integrator's Manual? I can't find it on the site nor on Google.
[20:47:40] <cradek> http://www.linuxcnc.org/docs/html/gcode_main.html
[20:47:45] <cradek> here is the online location
[20:47:57] <cradek> also this is the (very nice) quick ref http://www.linuxcnc.org/docs/html/gcode.html
[20:48:57] <archivist> and google finds http://www.linuxcnc.org/handbook/gcode/g-code.html
[20:49:51] <cradek> that one is less up to date
[20:50:36] <MASEngr> Nice short reference; I'm looking into how to set up the tool table for when we change / break something.
[20:52:00] <MASEngr> When you activate the "tool change position" command, does it retract Z first, or does it move all three axes at once?
[20:52:22] <archivist> cradek, first time ive seen that one, does it need a delete or a redirect to current
[20:53:03] <cradek> MASEngr: it moves in a straight line to the tool change position. in emc2.3 there are more options, including one to retract Z
[20:54:31] <archivist> you could not easily cater for all tooling shapes
[20:55:08] <archivist> I would assume one needs to program the exit in some way
[20:56:06] <cradek> if you are above the work (safety plane) when you do the tool change, it does not really matter - issuing a tool change with the tool in the work seems like it would be bad practice.
[20:56:27] <archivist> in one prog I rotate A over the side and upper cutting tool
[20:58:01] <MASEngr> Perhaps changing it so you can do more than one tool change position, and it goes to each one in sequence.
[20:58:15] <MASEngr> Yeah, I know - do I know C? ;)
[20:59:44] <cradek> here are the tool change position options that are new for 2.3: http://www.linuxcnc.org/docs/devel/html/config_ini_config.html#sub:%5BEMCIO%5D-Section
[21:03:08] <MASEngr> Ah, there we go. I've been looking for the tool table information, and now I've got it. Thanks.
[22:20:36] <MASEngr> Hello again. I've got the tool changing working, but it doesn't seem to have any effect.
[22:21:03] <MASEngr> So it will pause when you get to the change part in the g code then pop up the dialog waiting for you to change the tool.
[22:21:49] <MASEngr> Is it supposed to react to the tool change? It lowers to the same height again - it's like it doesn't read the lengths, or it doesn't care. It's more likely that I forgot something, but I can't find out what that would be.
[22:23:45] <BigJohnT> automagic tool change or manual tool change
[22:25:43] <MASEngr> manual
[22:26:50] <archivist> what are you expecting to happen
[22:26:53] <BigJohnT> I think it just pauses the program but should apply the new tool offset
[22:28:07] <toastydeath> my co-worker decided to play "guess what I'm thinking" with the setup sheet for the job I'm doing at work
[22:28:33] <toastydeath> the unintelligble series of numbers apparently meant he wanted the tool to have two diameter offsets
[22:28:55] <toastydeath> needless to say it cut a wee bit oversize with a .000 diameter
[22:29:18] <toastydeath> i hate his setup sheets, it's like a word hunt
[22:29:19] <MASEngr> Sorry, I was at the mill. The problem was in using G43 to set the tool in g code as well. I had mistakenly thought that doing the tool change would automatically set EMC to a different height.
[22:29:56] <MASEngr> So, when you follow up the T[X] with a G43[X], the heights change.
[22:31:03] <BigJohnT> * BigJohnT must go fetch dinner
[22:33:31] <anonimasu> ^_^
[22:34:30] <anonimasu> toastydeath: tell him he needs to make them better..
[22:34:31] <anonimasu> :)
[22:37:47] <toastydeath> no, he argues like i do
[22:38:26] <toastydeath> it would never work
[22:39:45] <anonimasu> argues like you do?
[22:40:14] <anonimasu> cant you just tell him that you are too stupid to gather what he means..
[22:41:28] <toastydeath> no, that won't work eithe
[22:41:29] <toastydeath> r
[22:41:42] <anonimasu> why not?
[22:41:49] <toastydeath> because he'll just say to get smarter
[22:42:22] <anonimasu> if you cant make the parts he wants because he cant write proper setup sheets I'd say it's a problem
[22:42:35] <toastydeath> yes but from his perspective it's because I don't know what I'm doing
[22:42:42] <toastydeath> IT'S CLEAR AS DAY, BECAUSE THE PAGE IS THERE, YOU SEE
[22:42:44] <toastydeath> CAN'T YOU READ
[22:42:50] <toastydeath> yes, yes i can read
[22:42:55] <toastydeath> the issue, sir, is that you can't write
[22:43:11] <toastydeath> and who the hell puts two diameters on one friggin' tool
[22:43:26] <toastydeath> what happened is he got lazy writing the program
[22:43:42] <toastydeath> and instead of doing a second pass, copypasta'ed it and used a different offset
[22:43:58] <toastydeath> and then documented the hack incredibly poorly
[22:43:58] <anonimasu> heh
[22:44:21] <toastydeath> i don't have a problem with hacks if you actually document what you did clearly
[22:45:09] <anonimasu> yep
[22:45:29] <anonimasu> what kind of control do you run?
[22:45:36] <anonimasu> heidenhain=
[22:45:37] <anonimasu> ?
[22:45:39] <toastydeath> this was a fanuc 0M
[22:45:42] <anonimasu> ah..
[22:46:12] <anonimasu> I dont know them(I know that on the heidenhains you can just add oversize or undersize comp on a tool call
[22:46:30] <toastydeath> there MAY be an option like that
[22:46:43] <toastydeath> probably not, thoughj
[22:46:44] <toastydeath> -j
[22:46:47] <anonimasu> which is convenient if you do hacks like that in mid program :p
[22:47:38] <toastydeath> haha, yeah
[22:47:41] <toastydeath> that would have been peachy
[22:47:46] <toastydeath> it's such a slackass hack, too
[22:47:51] <toastydeath> he just wanted to take a .001 pass.
[22:48:02] <toastydeath> so he used a whole different tool diameter?
[22:48:14] <toastydeath> whatever, man
[22:48:14] <anonimasu> yep
[22:48:43] <anonimasu> ^_^
[22:48:57] <anonimasu> it's weekend and I have two options
[22:49:02] <anonimasu> tomorrow if im lucky it rains.
[22:49:08] <anonimasu> then I'll study physics..
[22:49:11] <toastydeath> a) party, or b) party?
[22:49:12] <toastydeath> oh.
[22:49:24] <anonimasu> if im unlucky ther's good weather.. and that meand changing windows
[22:51:16] <anonimasu> means..
[22:51:16] <toastydeath> take a shower and claim it's raining
[22:51:16] <toastydeath> obviously
[22:51:28] <anonimasu> no party for me
[22:51:31] <anonimasu> I have nobody to party with
[22:51:57] <dmess> physics is a nice option on a rainy day
[22:52:17] <anonimasu> well, I've got lots of stuff to repetition
[22:52:28] <anonimasu> the new chapter is a boring one..
[22:52:41] <anonimasu> it's about coloumbs law.. -_-
[22:53:01] <dmess> yeah baby... ;(
[22:54:25] <archivist> more fun to get physical with a machine
[22:55:50] <anonimasu> hehe
[22:55:50] <anonimasu> I were planning on machining some parts
[22:55:50] <anonimasu> but that's like 20 minutes at the mill as I have the program already written
[22:55:50] <anonimasu> :)
[22:55:50] <dmess> so make 100
[22:55:50] <anonimasu> haha
[22:55:50] <anonimasu> it's a prototype
[22:55:50] <archivist> sell 80
[22:55:50] <dmess> i know the feeling
[22:55:50] <anonimasu> it's like set up tools... "NC START" and change tools 4 times
[22:55:50] <dmess> we are working out a new mfg plan for 1 gear at work from 80 hrs tool time to 32
[22:55:58] <anonimasu> I could reduce toolchanges but that gives me more machining time
[22:56:14] <dmess> the boys dont like it.. the cant finish their crosswords... waaaaa
[22:56:19] <archivist> gear to me is different to gear for you dmess
[22:56:21] <anonimasu> clearing lots of material with a 5mm endmill is pretty shitty :)
[22:56:33] <dmess> landing gear
[22:56:41] <archivist> gear wheel
[22:57:07] <dmess> as in the main fitting OF
[22:58:02] <dmess> http://www.messier-dowty.com/ im at the Toronto site
