[00:08:50] <alex4nder> yoh
[00:08:57] <alex4nder> Tecan: cool thanks
[01:20:22] <toastydeath> i just watched a video on how to set up a jointer
[01:20:30] <toastydeath> it's painful to watch woodworking people set up tools
[01:23:43] <mrsun> url?
[01:24:49] <toastydeath> lemme find it again
[01:25:09] <toastydeath> this is one of the better videos but it's what i was watching
[01:25:09] <toastydeath> http://www.youtube.com/watch?v=gO746cuRqV4
[01:25:24] <toastydeath> very informative on what adjustments jointers have, though
[01:29:18] <mk0> i compiled branch master. should i see 2.6.0 or 2.5.0 upon runnig?
[01:44:10] <cylly2> mornin'
[02:17:03] <DJ9DJ> moin
[02:28:38] <alex4nder> ok
[02:29:20] <alex4nder> time to do some HAL hacking
[02:29:27] <alex4nder> and then watch some game of thrones
[02:57:16] <archivist> jthornton, "The fixed jaw of the vise never moves" I almost never manage a vice position (spelling!) to last more than one job
[03:00:26] <archivist> jthornton, version date seems to predate its writing somewhat version 1.0, 2003-12
[03:00:49] <archivist> indicating the vice could include squareness too
[04:26:03] <mk0> about free of cost xchat for windows.
http://code.google.com/p/xchat-wdk/
[04:28:33] <mk0> http://www.xchat-wdk.org/
[06:23:55] <jthornton> archivist, if you move your vise that much you must have a rather quick and accurate way to indicate the vise in... you could write a paragraph or two if you like
[06:38:16] <jdhNC> are the slots in the bottoms of vices good enough to use for Y alignment?
[06:55:13] <awallin> hm, if you have rotated xy coords you could skip aligning the vise? and just rotate in the control..
[07:03:43] <jthornton> good enough depends on your requirements
[07:10:24] <jthornton> archivist, yea I just copied a template and started hammering away at it and didn't even think of the date part at the top
[07:23:45] <fliebel> What could cause a cnc mill to lock up? It uses worm gears, which sometimes block for no apparent reason.
[07:24:22] <jdhNC> is it turned on.
[07:24:24] <fliebel> it just goes step, step, step, step, thud, thud, thud...
[07:25:38] <fliebel> yes, it's on.
[07:26:30] <jdhNC> jthornton: When you are done, can you do one on material/tool setup for lathes also?
[07:27:05] <jthornton> I won't be done until I cover lathes :-)
[07:50:27] <Tectu> can EMC drive A4988 drivers?
[07:54:02] <alex_joni> pololu?
[07:54:32] <Tectu> alex4nder, #include <errno.h>
[07:54:32] <Tectu> #include <sys/stat.h>
[07:54:32] <Tectu> #include <sys/times.h>
[07:54:32] <Tectu> #include <sys/unistd.h>
[07:54:33] <Tectu> #include "stm32f10x_usart.h"
[07:55:03] <Tectu> oh my god
[07:55:11] <Tectu> sorry, that was copy&paste fail
[07:55:23] <TekniQue> #include <fail.h>
[07:55:29] <Tectu> alex_joni, this things:
http://reprapsource.com/en/show/6532
[07:55:33] <Tectu> TekniQue, indeeed
[07:55:58] <alex_joni> Tectu: looks step/dir, so I see no reason why not
[07:56:02] <jdhNC> A4988 looks like plain old step/dir. Nifty looking chip though. All-in-one.
[07:56:31] <Tectu> well, i use L297 atm, and they are in the dropdown menu, and i don't want to write stuff on my own
[07:56:37] <Tectu> so i ask if there is also support for them or not
[07:57:08] <jdhNC> nothing to write, that just sets timing values
[07:58:58] <Tectu> ok
[07:58:59] <jdhNC> 1uS min pulse width, 200nS step/dir change.
[07:59:11] <Tectu> where do you get that from?
[07:59:58] <jdhNC> http://www.allegromicro.com/Products/Motor-Driver-And-Interface-ICs/Bipolar-Stepper-Motor-Drivers/~/media/Files/Datasheets/A4988-Datasheet.ashx
[08:00:04] <Tectu> i am also not sure if EMC can handle 16th microstep
[08:01:02] <jdhNC> it doesn't care
[08:01:08] <jdhNC> a pulse is a pulse.
[08:01:47] <micges> if it's parport, you just will get slower speeds
[08:03:15] <Tectu> ok
[08:04:17] <jdhNC> A4988 will work with the same L297 settings. It could just run a little faster.
[08:04:36] <Tectu> ok
[08:04:42] <Tectu> i can take l297 settings?
[08:05:17] <jdhNC> http://www.st.com/internet/com/TECHNICAL_RESOURCES/TECHNICAL_LITERATURE/DATASHEET/CD00000063.pdf
[08:12:55] <alex_joni> Tectu: you can take L297 settings, but those are overly slow for the allegro chip
[08:13:07] <alex_joni> so it would be in your best interest to take smaller numbers ;)
[08:13:46] <Loetmichel> alex_joni: btw: MY L207 are driven with about a tenth of the "l297" settings
[08:13:52] <Loetmichel> L297
[08:14:02] <Loetmichel> an d run without any step loss
[08:17:30] <alex_joni> well, you have to take your chances :)
[08:37:48] <Jymmm> jthornton: where are you? still alive after testing the canon yesterday?
[09:20:32] <FredrikHson> hi does anyone know of any cam program that can handle 4 axis cutting of stl files preferably free
[09:36:49] <JT-Shop-2> http://gnipsel.com/cannon/videos/cannon01.mov
[09:53:23] <Jymmm> JT-Shop: Nice!!!
[09:53:30] <JT-Shop> thanks
[09:53:50] <JT-Shop> that was the 3rd shot as I recall
[09:54:04] <jdhNC> can't see the videos here... What do you shoot at?
[09:54:27] <JT-Shop> might take awhile to load
[09:54:31] <JT-Shop> a tree

[10:13:17] <jdhNC> yes
[10:13:28] <JT-Shop> that didn't work
[10:13:57] <JT-Shop> is photo 5 and 7 the same for you?
http://gnipsel.com/cannon/cannon.xhtml
[10:15:36] <jdhNC> nope
[10:15:38] <Loetmichel> no
[10:15:48] <jdhNC> you are cached
[10:16:15] <FinboySlick> JT-Shop: That cherry wood?
[10:16:23] <FinboySlick> It's beautiful.
[10:17:03] <JT-Shop> yea, got to be on my end
[10:17:33] <JT-Shop> no it is white oak with Olympic Maximum sealer or whatever you call it
[10:17:50] <JT-Shop> clear finish
[10:17:59] <JT-Shop> the wheels are hickory
[10:22:51] <Tom_itx> JT-Shop i gotta clear files out of my brouser sometimes when i'm working on my pages
[10:23:31] <JT-Shop> I'm using firefox but starting to not like it anymore
[10:23:44] <Tom_itx> i've been using it lately
[10:25:11] <Tom_itx> 8..12 didn't load
[10:27:02] <JT-Shop> silly gimp changed the extension from .jpg to .JPG and...
[10:27:17] <JT-Shop> it will work now
[10:27:47] <Tom_itx> 10..12 didn't
[10:27:59] <JT-Shop> nothing there to load yet
[10:29:46] <JT-Shop> ok refresh now

[10:32:28] <Tom_itx> yes it does
[10:35:00] <Jymmm> JT-Shop: hold down SHIT and click on REFRESH, if that doesn't work, then clear your browser's cache
[10:35:41] <JT-Shop> you skipped the part about me solving the problem
[10:35:55] <Jymmm> my bad
[10:36:02] <JT-Shop> LOL
[10:50:57] <JT-Shop> Tom_itx: one more photo loaded

[10:52:34] <Tom_itx> what's wrong with this picture?
http://gnipsel.com/cannon/cannon-04.xhtml
[10:52:50] <JT-Shop> lol
[11:17:21] <alex4nder> morning
[11:21:07] <ReadError> sup
[11:49:16] <DrZimmerman> hello everyone
[11:49:37] <JT-Shop> yes
[11:49:44] <DJ9DJ> indeed
[11:49:46] <DJ9DJ> hi there :)
[11:50:04] <DrZimmerman> i found very little information about linuxcnc and CanOpen/CanMotion interfaces, is this supported?
[11:51:07] <JT-Shop> I'm suprised you found any information on Can that relates to linuxcnc
[11:51:32] <JT-Shop> a couple of components use modbus in user space
[11:51:54] <DrZimmerman> i found some forum entries debating this matter, but nothing usable
[11:52:03] <JT-Shop> ah, ok
[11:52:10] * djdelorie couldn't even find a cheap CAN card for the PC
[11:52:20] <DrZimmerman> hmm userspace, but i thought cnc control needs realtime kernel drivers?
[11:52:41] <JT-Shop> yep the control does but not everything has to be real time
[11:53:18] <JT-Shop> does Can rely on a smart driver down stream from the control?
[11:57:26] * JT-Shop goes to make half of a peanut butter sandwich...
[11:58:14] <DrZimmerman> i have no clue, never used Can before but i get a new job soon in which i probably have to learn all these things and i'm dreaming of a DIY cnc since some time now
[12:03:05] <IchGuckLive> hi all
[12:03:48] <jthornton> hi
[12:04:19] <IchGuckLive> B)
[12:04:50] <jthornton> can is not usually used with DIY cnc more of an industrial communications thing
[12:05:57] <jthornton> we have some servo drives in some of the equipment we make that communicate amongst themselves using Can
[12:10:55] * jthornton wanders off to take a nap
[12:11:25] <IchGuckLive> i did a banana
[12:11:33] <IchGuckLive> ;-)
[12:12:52] <jthornton> a banana on my pb sandwich would have been good
[12:13:22] <IchGuckLive> sandwitch is always good i got a thuna here
[12:35:00] <alex4nder> sup
[12:47:34] <jdhNC> it just says " adjust them like the X one"
[13:41:28] <JT-Shop> nots: are you using chatzilla?
[14:29:01] <gene__> hello!
[14:29:31] <DJ9DJ> hi gene-ious
[14:29:54] <gene__> question re encoder module (howdy DJ9D)
[14:31:51] <gene__> index is not propagating, so velocity is never reset. I can start it at a 1 requested but it gradually, over the next minute or so goes up to half speed. What am I missing?
[14:35:34] <gene__> IOW can I send Z-phase back into that same pin? It says its bidi
[14:38:11] <gene__> quick answer, no
[14:41:49] <jdhNC> ok!
[14:50:53] <DJ9DJ_> re
[15:27:27] <JT-Shop> gene__: you still here?
[15:39:57] <Jymmm> JT-Shop: Glad to see you still alive, didn't see you in the morning so wasn't sure =)
[15:41:26] <tjb1> I just love windows updates :)
[15:47:59] <JT-Shop> I'm not sure either...
[15:49:07] <Jymmm> lol
[15:49:16] <Jymmm> JT-Shop: what that you had your legs still?
[15:56:07] <JT-Shop> well peg legs now and a hook on one arm
[15:56:24] <gene__> yes, staring at halscope which shows pid.0.output is making a square wave
[15:56:54] <DJ9DJ> gn8
[15:58:41] <gene__> And occupying about 3.5 divs at 200v/div. Motor is buzzing at about 150 hz
[16:03:13] <gene__> Is there some way to turn the error gain down to stop the oscillation?
[16:03:55] <gene__> its running like a straight comparator with a deadband
[16:04:55] <JT-Shop> what ya working on gene__ ?
[16:05:27] <gene__> My lathes hal file
[16:05:45] <JT-Shop> for your spindle?
[16:06:18] <gene__> yes, trying to make the closed loop speed control work
[16:07:15] <JT-Shop> VFD drive?
[16:08:25] <gene__> whatever is in this, with one of Duncan's speed control interface boards. Normal brushed motor, and normal miini-lathe controller board.
[16:09:43] <JT-Shop> one of those c spindle drives from cnc4pc?
[16:09:53] <JT-Shop> like a C41
[16:09:58] <gene__> c41 I think
[16:11:20] <gene__> Its behaving normally until I try to plug the pid thing in, using the 1,101,201,301, ect sequence from AXIS.
[16:12:21] <gene__> If I set the feedback signal gain way down, then it runs smoothly at about 1/3rd rps, but in 5 ninutes it will be up to 500 rpm
[16:13:22] <JT-Shop> doesn't that board take stepper pulses and convert it to PWM or something?
[16:14:43] <gene__> feedback signal is from the encoder.0.velocity (no, its a pwm to analog that connect where the hand control was on the machines board).
[16:15:08] <gene__> very simple, just optro-isolated.
[16:19:03] <gene__> feedback is encoder.0.velocity in rps =>motion.spindle-speed-in => scale.1.in | scale.1.out=> abs.1.in => abs.1.out =>pid.0.feedback
[16:19:14] <gene__> or is supposed to be. ;-)
[16:20:52] <gene__> that feeds pwmgen.value, and that is the signal oscillating like crazy.
[16:21:17] <JT-Shop> and encoder.0 is the encoder on the spindle motor?
[16:21:28] <gene__> yes
[16:22:17] <gene__> and its working great, except for a lot of noise in the velocity output
[16:22:59] <JT-Shop> is it a home made encoder?
[16:23:51] <gene__> yep. a pix of its output in on my web page, in Genes-os9-stf/eagle subdir
[16:25:15] <JT-Shop> what's your web page?
[16:26:39] <gene__> I might see something that is better visualized if I landscape print that hal file and its dinner time so I'd better go feed the better half. Web pagfe is in the sig of one of my messages on the list
[16:26:57] <JT-Shop> ok
[16:27:04] <gene__> You going to be around for a few hours yet?
[16:27:13] <JT-Shop> couple at least
[16:27:40] <gene__> Ok, that is long enough to hit the steak house or something
[16:28:00] <JT-Shop> can you post your hal file to pastebin?
[18:11:27] <r00t4rd3d> what i do
[18:11:30] <r00t4rd3d> http://imgur.com/a/9jvLj
[18:17:45] <cradek> when you do a heated floor like that, do you have to do anything special to allow it to expand and contract?
[18:24:39] <r00t4rd3d> nope
[18:24:57] <r00t4rd3d> just sets in the concrete
[18:25:14] <Tom_itx> cradek,
http://eds.dyndns.org/~ircjunk/shop/dscn8680.jpg
[18:25:22] <r00t4rd3d> thats not the main heat supply
[18:25:25] <Tom_itx> rue did his shop that way as well
[18:25:43] <r00t4rd3d> just a comfort zone
[18:26:01] <cradek> heh I mean the floor changing size, not the tubing
[18:26:18] <cradek> is it just pex like for water, or is it special?
[18:26:28] <r00t4rd3d> pex
[18:26:29] <Tom_itx> yeah i think it's pex
[18:26:49] <r00t4rd3d> we poured it today
[18:27:07] <Tom_itx> rue's got a bunch of pics in that dir
[18:27:43] <jdhNC> what I do:
http://www.physicstogo.org/images/features/reactorrods-large.jpg
[18:28:18] <r00t4rd3d> we normally dont do stuff like that
[18:28:43] <r00t4rd3d> just frame mainly
[18:30:06] <r00t4rd3d> only 3 of us but we had some help today
[18:34:43] <JT-Shop> anyone have a clue what the blue thing is on top of the commutating reactor is?
http://imagebin.org/211467
[18:35:38] <Jymmm> looks like it says SEIMENS
[18:36:06] <pfred1> Tom_itx looks like the baby pump hose to me
[18:41:19] <JT-Shop> yea, it does have $eimens on it
[18:47:26] <tjb1> Is there a setting in linuxcnc to set an output if machine speed reaches 80% of program speed
[18:49:25] <JT-Shop> no, but you can roll your own
[18:49:31] <JT-Shop> in HAL
[18:53:20] <tjb1> Was that in response to my question?
[18:53:33] <JT-Shop> yep
[18:54:43] <tjb1> Can you elaborate on that, I have never used linux
[18:55:11] <JT-Shop> has nothing to do with linux really
[18:55:23] <tjb1> Ive tried to find the setting in Mach3 and either it doesn't exist or I'm blind
[18:55:25] <JT-Shop> the hal pin motion.requested-vel has the current F number in it
[18:55:49] <JT-Shop> mack3?
[18:56:08] <tjb1> Yes, its another cnc controller software
[18:56:19] <djdelorie> my one HAL component reads the current velocity:
http://www.delorie.com/cnc/machineactive.comp
[18:57:25] <tjb1> I need a way to find out when the program is cutting an arc or something that would reduce the speed from straight moves to pause the torch height control so it doesn't dive
[18:57:40] <JT-Shop> yea, I know what mack3 is what does that have to do with your question?
[18:57:53] <JT-Shop> what THC are you using?
[18:58:07] <tjb1> I am making my own
[18:58:23] <JT-Shop> what inputs does it take?
[18:58:37] <JT-Shop> an up down one or one that reads voltage?
[18:58:58] <tjb1> Using the 50:1 output on plasma, and motion start
[18:59:11] <tjb1> then running the z-step and z-dir through it
[18:59:25] <tjb1> just need a way to pause it on corners and such
[18:59:35] <JT-Shop> does your THC compare the voltage and make adjustments on Z
[18:59:52] <tjb1> yes
[19:00:17] <tjb1> Im going to use an arduino to take the 50:1 and compare it to a set number and then take over the z-step and z-dir when motion start is active
[19:00:18] <JT-Shop> did you know LinuxCNC has a THC component?
[19:01:07] <tjb1> Still waiting on it to download at the moment
[19:01:28] <JT-Shop> linuxcnc or the THC component?
[19:01:33] <tjb1> linuxcnc
[19:02:04] <JT-Shop> here is the THC componet that I wrote for the Mesa THC card
http://linuxcnc.org/docview/html/man/man9/thc.9.html
[19:03:12] <JT-Shop> it is included with LinuxCNC and takes a velocity input as well as a few other inputs and hijacks the Z when enabled to keep the voltage constant
[19:05:32] <tjb1> How much is that card?
[19:05:46] <JT-Shop> holy crap it is 7pm and I've not made a cannon part yet...
[19:05:55] <JT-Shop> let me find it for you
[19:05:58] <Tom_itx> holy crap!
[19:06:05] <tjb1> Ah, found it...$199
[19:06:21] <tjb1> PCI Anything I/O - 72 I/O bits?
[19:06:59] <JT-Shop> wrong card the THC is $70
[19:07:57] <tjb1> So the 5i20 isn't needed
[19:08:53] <JT-Shop> well you need something better than the parallel port yes... I just refitted my plasma with a 5i25/7i76 combo and along with the THC card I'm good to go
[19:10:10] <JT-Shop> 7i76 Plug-N-Go 5I25+7I76+IEEE1284 cable kit 199
[19:10:33] <JT-Shop> THCAD-10 High isolation A-D, 10V 69
[19:10:41] <JT-Shop> or THCAD-10 High isolation A-D, 10V 69
[19:11:06] <JT-Shop> tjb1: what plasma cutter do you have?
[19:11:19] <tjb1> powermax 45
[19:12:34] <JT-Shop> is that a HF start torch?
[19:12:52] <JT-Shop> that a Hypertherm?
[19:14:08] <tjb1> yes hypertherm, hf I'm not sure
[19:14:24] <JT-Shop> mine is a 1250
[19:15:50] <JT-Shop> oh, that is the new generation of plasma from them
[19:15:56] <tjb1> Now known as the powermax 85?
[19:17:19] <JT-Shop> yea, I think so but the 85 is improved from the 1250
[19:17:36] <JT-Shop> I think better consummable life and better cut
[19:18:09] <tjb1> Im making a table as my senior project
[19:18:25] <tjb1> The THC isn't required but I would rather make one instead of buying one
[19:18:29] <JT-Shop> not trying to influnce you but have you seen my plasma?
[19:18:42] <tjb1> Not that I know of
[19:19:22] <JT-Shop> couple of shots here
http://gnipsel.com/shop/plasma/plasma.xhtml
[19:19:57] <JT-Shop> more here

[19:20:10] <JT-Shop> you making a water table?
[19:20:25] <tjb1> Yes
[19:20:51] <JT-Shop> you only need some sodium nitrite and pysan 20 and H2o for coolant
[19:21:17] <tjb1> http://a4.sphotos.ak.fbcdn.net/hphotos-ak-ash4/414905_3554298172111_1112377031_33394573_527938187_o.jpg
[19:21:23] <tjb1> that is the latest drawing I have
[19:22:17] <JT-Shop> sodium nitrite is 0.05% by weight and follow directions on physan20
[19:22:50] <JT-Shop> how are you going to drive the axis?
[19:23:16] <tjb1> rack and pinion
[19:23:22] <tjb1> like the cncrouterparts setup
[19:23:42] <JT-Shop> nice, I went with timing belts
[19:24:08] <tjb1> All your motion done on the (teflon?) parts?
[19:24:25] * Jymmm suspects delrin
[19:24:30] <JT-Shop> yea, you just have to clean them from time to time
[19:24:42] <JT-Shop> Jymmm: might be right
[19:25:04] <Jymmm> JT-Shop: that'll be a first, or amybe even a second.
[19:25:06] <JT-Shop> tjb1: btw Frameworld slides are better than 80/20 slides
[19:25:09] <JT-Shop> LOL
[19:25:29] <tjb1> frameworld slides?
[19:26:07] <JT-Shop> yea, they make the same stuff 80/20 make but better stuff IMHO
[19:26:12] <Jymmm> JT-Shop: ever play with Potassium Nitrate?
[19:26:34] <tjb1> They cheaper than 80/20?
[19:26:42] <tjb1> All the extrusions in my drawing came out for $404
[19:26:56] <tjb1> table is 113" long by 73" wide
[19:27:20] <JT-Shop> maybe some fulminate of mercury from time to time
[19:27:43] <JT-Shop> you just have the three pcs of extrusion right?
[19:28:12] <tjb1> 4, 2-3030 113", 1-3030 73" and 1-1530 12"
[19:28:36] <Jymmm> JT-Shop: Do you think if I soaked cotton in a water based Potassium Nitrate solution and let it dry, it would lower the flashpoint of the cotton?
[19:28:48] <JT-Shop> why not mount the Y rails onto the tubing? save some money
[19:29:05] <JT-Shop> Jymmm: dunno, give it a try and let me know
[19:29:07] <tjb1> Easier to mount rack and crs onto the extrusion
[19:29:17] <tjb1> and easier to adjust the rails
[19:29:18] <Jymmm> JT-Shop: lol, bastard!
[19:29:24] <JT-Shop> yea
[19:30:05] <tjb1> Rather not drill all the holes in the rails and try to keep it square while welding the frame together
[19:30:14] <JT-Shop> seems simpler to just screw the rail to the tubing
[19:30:31] <JT-Shop> gotcha
[19:31:04] <tjb1> The way the extrusion is mounted, I can shim it if needed
[19:31:08] <JT-Shop> you done a lot of fabricating with steel?
[19:31:09] <tjb1> Hopefully...
[19:31:21] <tjb1> Do quite a bit at home
[19:31:27] <tjb1> nothing big like this
[19:31:54] <JT-Shop> ok, I was going to give you a tip but you must know if you have done quite a bit
[19:32:19] <tjb1> I can always learn
[19:32:19] <JT-Shop> I do it for a living sometimes
[19:32:24] <tjb1> Go ahead and share
[19:32:34] <Tom_itx> when you're not building cannons
[19:32:36] <JT-Shop> tack the whole thing together before you weld anything up
[19:32:40] <JT-Shop> yea
[19:32:46] <tjb1> I thought about that
[19:33:02] <tjb1> just enough to support itself then it would resist the warping more
[19:33:03] <JT-Shop> and triple check for square before welding up
[19:33:26] <djdelorie> do not look at spark with remaining eye
[19:33:46] <JT-Shop> if your welding hot do a little in each area so you don't build a warp into the tubing
[19:33:52] <JT-Shop> LOL
[19:34:22] <tjb1> Ive had the arc eye from reflection on snow...
[19:34:23] <JT-Shop> you can't have enough clamps, straps etc holding it in place when you put it together
[19:35:03] <tjb1> Had to be the worst 2-3 days of my life
[19:35:23] <Jymmm> JT-Shop: build upside down???
[19:35:50] <JT-Shop> yea, know what you mean but I got my lesson in the stack of a destroyer installing the splitters and I looked the other way but the walls were aluminum...
[19:36:06] <JT-Shop> but, where did that come from
[19:36:08] <tjb1> What is the best way to accurately measure long distances to keep everything the same
[19:36:53] <JT-Shop> for frames I just use a good steel tape measure... one that has not been dropped and the end it bent you know
[19:37:04] <JT-Shop> s/it/is
[19:37:27] <djdelorie> and never "tighten" the grommets on the end of a steel tape measure
[19:37:37] <Jymmm> for squareness?
[19:37:40] <Jymmm> djdelorie: heh
[19:37:42] <tjb1> Gonna take all the 2x2s and square them all to the correct length at school
[19:38:03] <JT-Shop> hard to say Jymmm I'd tack each side together first then add the rest
[19:38:21] <Jymmm> JT-Shop: k
[19:38:48] <Jymmm> You can measure diagnally to check for squareness too
[19:38:58] <JT-Shop> you have to
[19:39:27] <JT-Shop> I'd tack one side together then put the second one on top of it and tack it together
[19:39:49] <JT-Shop> lots of clamps and scrap to hold everything in the same place
[19:40:07] <tjb1> Alright
[19:40:24] <tjb1> Any comments on the design beside the extrusions?
[19:40:41] <tjb1> I have about 3 months to get the design ironed out
[19:40:49] <JT-Shop> looks straight fwd to me
[19:41:12] <JT-Shop> I'd move the long lower braces to the sides though
[19:41:37] <tjb1> the 2 running down the middle?
[19:41:38] <JT-Shop> so the sides are very secure top to bottom
[19:41:41] <JT-Shop> yea

[19:42:45] <Jymmm> man those are a pita, keeps asking to download instead of viewing them
[19:43:18] <JT-Shop> holy crap are you using 3x3 for the Y axis rails?
[19:44:11] <tjb1> Yes
[19:44:35] <JT-Shop> bit overkill don't you think with the steel tube under it?
[19:44:38] <tjb1> Its also going to be a router in the future
[19:45:11] <JT-Shop> steel under it...
[19:45:38] <JT-Shop> I'd make the Y axis sleds longer for a router
[19:45:38] <Jymmm> I dont see any place for energy chain, limit switches, etc
[19:46:10] <JT-Shop> chow time here
[19:46:10] <tjb1> JT-Shop: The black bearings?
[19:46:24] <tjb1> Jymmm: Im not that good at solid works yet
[19:46:52] <Jymmm> tjb1: no, not drawing them in, just longer than travel to allow for mounting them
[19:47:17] <Jymmm> if you have 48" travel, should add an extra 4-6"
[19:47:30] <Jymmm> as example
[19:47:35] <tjb1> Well the long axis is 113" and I only need 96
[19:47:51] <Jymmm> ok =)
[19:47:57] <tjb1> I think the side is 60? and I need 48
[19:48:10] <Jymmm> wait, how long are the slides?
[19:48:24] <tjb1> I have 3 inductive sensors that I am going to mount on the carriages and put a pickup at each end
[19:48:30] <tjb1> The long extrusions?
[19:48:36] <Jymmm> the black things
[19:49:24] <Jymmm> 4" 6" 10" long
[19:49:25] <Jymmm> ?
[19:49:28] <tjb1> 8"
[19:49:32] <tjb1> Had to look it up, sorry
[19:49:36] <Jymmm> =)
[19:49:59] <tjb1> http://www.cncrouterparts.com/extended-linear-carriage-with-abec-7-bearings-p-35.html?cPath=21
[19:50:09] <tjb1> The z-axis ones are around 4"
[19:52:15] <tjb1> I could probably go with 1530 on the long axis but that would make things a little too tight where the rack has to bolt on
[19:55:17] <tjb1> I need some help with installing ubuntu
[19:56:10] <tjb1> "No root file system is defined."
[20:37:54] <tjb1> Anyone have recommendations for a tig welder under $2k?
[20:45:14] <Tom_itx> a small miller
[20:45:30] <Tom_itx> i'd get one big enough to have a good pulsed feature
[20:51:25] <tjb1> http://www.harrisweldingsupplies.com/miller-maxstar-200-sd-tig-welder-903701.aspx
[20:53:02] <Tom_itx> Pulsed TIG (GTAW-P) with DX and LX models
[20:53:49] <Tom_itx> get a foot pedal too
[20:55:20] <tjb1> what do you think about -
http://www.harrisweldingsupplies.com/lincoln-precision-tig-225-tig-welder-ready-pak.aspx
[20:56:51] <Tom_itx> get one that has the features you need. i got a miller mig because i felt the wire feeder was built better than the lincoln
[20:57:13] <Tom_itx> they're equivalent overall i'd say
[20:58:01] <Tom_itx> try one out
[20:58:12] <Tom_itx> see if it does what you need
[21:04:49] <tjb1> What exactly do the pulse features do
[21:09:09] <Tom_itx> gives you better control on things like thin aluminum etc
[21:09:19] <Tom_itx> so you don't blow thru
[21:12:01] <tjb1> brb
[21:16:03] <tjb1-linux> alright got it.
[21:19:32] <tjb1-linux> where do you edit the notifications that pop up in ubuntu?
[22:09:40] <alex4nder> hey
[22:10:16] <jdhNC> hey!
[22:10:27] <alex4nder> how's it?
[22:15:03] <jdhNC> good question. How is it?
[22:15:47] <alex4nder> it's good over here
[22:15:48] <Valen> theres two kinds of pulse, high and low frequency
[22:15:57] <alex4nder> except for some stepper stalling
[22:15:58] <Valen> bah too late
[22:16:13] <Valen> alex4nder: moar amps
[22:16:22] <alex4nder> probably not going to happen.
[22:16:49] <alex4nder> but I'm already going 2x the speed the machine is rated for. so now I'm just being greedy
[22:17:05] <jdhNC> greed is good!
[22:17:17] <alex4nder> ok gordon
[22:18:18] <alex4nder> it's pretty close to milling time.
[22:19:09] <Tom_itx> miller time! did somebody say it's miller time?
