[00:00:02] <cpresser> paresh: yes. search for it on youtube. its possible
[00:00:20] <paresh> i already search
[00:00:31] <paresh> but some confusion
[00:04:38] <Jymmm> Thetawaves: Kinda like the idea that you can use natural gas in a pinch, but propane for long term, and gasoline for whatever
[00:07:02] <Thetawaves> natural gas would be ideal because it's provided at my door
[00:07:13] <Thetawaves> i would have to get propane delivered
[00:07:17] <Jymmm> Thetawaves: in your case, natural gas for a permantent installation, and propane for a backup
[00:07:32] <Thetawaves> yeah, exactly
[00:07:37] <Jymmm> even a few 20# tanks
[00:08:00] <Jymmm> My gen is portable, so doesn't really apply.
[00:08:07] <Thetawaves> propane stores much better than gasoline too
[00:08:15] <Jymmm> for natural gas that is
[00:08:18] <Jymmm> oh big time
[00:08:39] <Jymmm> and I have 3 20# tanks for my portable heater
[00:08:57] <Jymmm> I use in the garage =)
[00:09:04] <Jymmm> I love that lil heater!!!
[00:09:24] <Thetawaves> how long does that last?
[00:10:00] <Jymmm> 20# tank for the heater lasts about 100+ hours on the low setting
[00:10:21] <Jymmm> there's only low (4000btu) and high (9000btu)
[00:10:21] <Thetawaves> impressive
[00:10:48] <Jymmm> the Big Buddy goes up to 18000 BTU
[00:11:24] <Jymmm> It's nice in the fact that it uses 1# disposable tanks
[00:11:31] <Jymmm> but they dont last long =)
[00:12:00] <Jymmm> so I have the 10ft hose for it that attachs to 20# tanks which I get refilled for $16 out the door
[00:12:56] <Jymmm> I picked up cheap old tanks off craigslist, then took them to Lowes for $21 exchanged for newer tanks. then I just get them refilled after that.
[00:13:12] <Thetawaves> damn!
[00:13:18] <Thetawaves> can i do that?
[00:14:07] <Jymmm> Thetawaves: They can't be older than 12 years without being recertified, but lowes will tank back ANY tank for exchange. Just be usre to select which tank you get from them so it's no mor ethan just months old.
[00:14:20] <Jymmm> the mfg date in on the collar... yyyy-mm
[00:14:21] <Thetawaves> i bet you lowes doesn't do that here
[00:14:28] <Jymmm> I bet they will =)
[00:14:34] <Jymmm> all of them do that.
[00:14:44] <Thetawaves> cool
[00:14:49] <Jymmm> Lowes is the CHEAPEST propane exchange around.
[00:16:05] <Jymmm> Thetawaves: Sorry, it's MM-YY on the TOP LEFT of the collar
[00:16:28] <Thetawaves> ok
[00:17:03] <Jymmm> Thetawaves: Jan 1999 http://upload.wikimedia.org/wikipedia/commons/f/fe/Propane_tank_20lb.jpg
[00:17:34] <Jymmm> Thetawaves: see it?
[00:18:03] <Thetawaves> yeah i see i t
[00:18:18] <Jymmm> Thetawaves: =)
[00:18:37] <alex4nder> yoh
[00:18:38] <Jymmm> Thetawaves: Great way to get cheap tanks
[00:19:26] <Jymmm> Thetawaves: BTW, the newest tanks at lowes seem to have a glossy paint finish on them too
[00:22:52] <Jymmm> Thetawaves: Nicer setup it seems http://www.youtube.com/watch?v=DpknaAPTQ9U
[00:29:42] <Jymmm> Thetawaves: WOW, that's one of the best intuitive videos I've ever seen on YT.
[00:29:53] <Thetawaves> yeah thats a good setup
[00:30:42] <Thetawaves> same components though
[00:30:55] <Thetawaves> i wonder if it's possible to diy that liquid->gas converter
[00:31:04] <Thetawaves> in the hot climates, you might not even need that
[00:31:07] <Jymmm> Oh sure, but a far better setup... quick release. no bulky regulator bolted to the side
[00:31:32] <Jymmm> Though I would sorta reinforce the 2nd reg on the tank.... looks scary =)
[00:32:00] <Thetawaves> i was thinking that too
[00:32:38] <Jymmm> Maybe the 1st attached to the tank with a 12" hose to the 2nd reg "hanging" aroudn the ring of the tank.
[00:33:04] <Jymmm> or even MAG mount to the tnak itself
[00:33:44] <Thetawaves> i was thinking stack the regulator and converter
[00:33:52] <Thetawaves> with u pipe
[00:33:54] <Jymmm> NICE.... at the end he just disconects the quick release while it's running and no gas leaks
[00:34:45] <Jymmm> I was thinking a "ring" around the neck of the tank, connected to a L bracket, then a magnet so it doesn't flop around.
[00:35:58] <Jymmm> The ring having a 9" ID to just slip over the neck and a 10 or 11" OD
[00:36:21] <Thetawaves> -0.5wc? hmmmmm
[00:36:27] <Jymmm> vacuum
[00:36:38] <Jymmm> but I have nfc on those regulators
[00:37:52] <Jymmm> Thetawaves: This is the hose I bought. The are now black with no plastisizers in them http://www.northerntool.com/shop/tools/product_200362084_200362084
[00:38:06] <Jymmm> Thetawaves: no wrench needed either
[00:39:32] <Jymmm> This is the BIG Buddy http://www.northerntool.com/shop/tools/product_200307957_200307957
[00:40:21] <Jymmm> Thetawaves: This is the one I have http://www.northerntool.com/shop/tools/product_200395499_200395499
[00:40:33] <Jymmm> that's a good price too $80
[00:41:17] <Jymmm> Thetawaves: you can buy the adapter to refill #1 tanks from 20# tanks too if you like
[00:49:01] <Thetawaves> hmmm
[01:55:43] <DJ9DJ> moin
[02:13:12] <Jymmm> hola
[02:15:30] <micges> ahoj
[02:32:48] <Jymmm> I really don't know how useful this information is to anyone, but 1" 8020 extrusion fits perfectly at a 45 degree angle into a 0.125" thick wall 0.750" wide aluminum C-Channel...

[03:27:16] <samkan> Hi, is it possible to merge a two hal file in one? sounds strange question?
[03:27:44] <samkan> but Yes, i need to merge two hal file in one, I am using linux cnc for raster as well as vector and both hal file are different
[03:40:22] <Loetmichel> mornin'
[03:45:48] <ReadError> hey
[03:49:54] <paresh> hal file understanding ?
[03:53:48] <samkan> anyone there..?
[04:48:34] <samkan> Hi need help on hal file !! anyone out there... !!
[06:30:46] <gmagno> hello, you guys know the best way to verify if a nema 17 motor is working? I bought one of those TB6560 driver board + 3x nema 17 motors kit, but since I can't put it to work with the linuxCNC software, I am considering the motors might have some problem (it is always hardware fault... :P ) How can I check if the stepper motors are ok?
[06:31:54] <gmagno> I am considering applying some voltage to one of the coils, but I wouldn't like to burn the motor... :-/ This is the kit I bought: http://www.ebay.com/itm/300654822440?_trksid=p5197.c0.m619
[06:33:19] <Valen> if the voltage is below the voltage stamped on the motor it should be ok
[06:36:40] <gmagno> Valen, THe problem is that I can't find a max specified voltage... They say the motor has the following current and resistance scpecifications: 1.8ohm/phase and 1.8A/phase. Should the operating voltage be 1.8*1.8? :-S
[06:36:54] <Valen> V = IR
[06:37:02] <Valen> so yes
[06:46:49] <gmagno> Ok, I should find a 3V power supply now... :-S
[06:47:02] <Valen> just use a AA battery
[06:47:13] <Valen> you should see it jump and it'll be hard to turn
[06:49:58] <gmagno> Valen, gonna do just that!
[06:51:56] <gmagno> Valen, there should be no problem in actuating only one coil as far as i know, right? (there are some shaft positions where only one of the coils is being actuated, right?)
[06:53:12] <Valen> should be fine
[06:53:29] <Valen> disconnect it from any other electronics first though
[07:01:15] <jthornton> archivist, for your amusement http://gnipsel.com/linuxcnc/tutorial/index.html
[07:04:39] <mrsun> oo nice =)
[07:07:48] <jdh> gmagno: do the motors lock up when you power the board?
[07:11:53] <gmagno> jdh, I'm not sure what lock up means, but when I run the stepconf wizard, and test one of the axis, pressing the arrows I can hear that typical sound of a shaft turning, but nothing really moves... It sounds like something is moving inside but the shaft does not
[07:13:19] <Tom_itx> then maybe they are wired wrong
[07:13:46] <Loetmichel> gmagno: when the drivers are powered the Stepeprs should be "locked" in place, if you try to turn them by hand you have to use MUCH more force opposed to drivers being off
[07:13:48] <Tom_itx> i use a 1.5v battery to find what i need sometimes
[07:13:50] <Tom_itx> or a meter
[07:14:47] <Loetmichel> hmm, do you have couplings on the stepper shafts?
[07:15:23] <Loetmichel> maybe the stepeprs turn but the leadsrews not because of slipping couplings?
[07:19:53] <jdh> or step timings are way off
[07:19:58] <gmagno> Loetmichel, I have the motors unloaded. They only have a little flag to tell me if they move. About the wiring, I'm almost sure (I'm never completely sure about anything...) that they are well connected. Ive done some measurements with a multimeter and also did that test of turning the shaft when a coil is shunted
[07:21:13] <gmagno> ok, I just did that test of applying a DC battery to the motor, and the shaft did move a tiny bit which I believe is good
[07:21:26] <gmagno> gonna do that for the other two
[07:27:05] <Loetmichel> gmagno: if you connect the two coils of the stepper in this manner to the battery the stepper should move continously (one tiny step at a time)
[07:27:06] <Loetmichel> coil1 + -
[07:27:07] <Loetmichel> coil2 + -
[07:27:07] <Loetmichel> coil1 - +
[07:27:07] <Loetmichel> coil2 - +
[07:27:07] <Loetmichel> repeat from start
[07:27:46] <Loetmichel> if it does: steppers ok, then something with your drivers and/or cabling isnt ok
[07:30:55] <jdh> do all steppers fail to operate?
[07:31:23] <gmagno> jdh, yes. Loetmichel, is that a series, or paralel?
[07:31:47] <Loetmichel> gmagno: that is seperate
[07:32:06] <Loetmichel> coil 1 energized +- , coil2 open
[07:32:08] <jdh> not likely to be a motor problem then.
[07:32:15] <Loetmichel> coil 1 energized +- , coil1 open
[07:32:18] <Loetmichel> and so on
[07:32:40] <gmagno> Loetmichel, how should th shaft move continuously?
[07:32:45] <Loetmichel> thats the full step sequence the stepper driver does also
[07:33:19] <Loetmichel> every time you energize a coil in this sequence the shaft will move a step in the same direction
[07:33:38] <gmagno> ah i see
[07:34:58] <gmagno> jdh, I'm almost sure now that it is not a motor problem. I'm gonna do the energizing sequence Loetmichel suggests
[07:35:55] <Loetmichel> gmagno: do you have the right pins in the linuxcnc config?
[07:36:29] <Loetmichel> 'cause the "movement sound" but no movement has occured to me as i had spitched the pins for step and dir in the config
[07:36:37] <Loetmichel> switched
[07:36:49] <Loetmichel> accidentally
[07:37:17] <Loetmichel> which driver board do you have?
[07:37:47] <gmagno> I'm following this guy procedure: http://www.youtube.com/watch?v=oiXjSZ3tIr0 My board is this one: http://www.ebay.com/itm/300654822440?_trksid=p5197.c0.m619
[07:39:18] <Loetmichel> so do you have a pinout of YOUR driver board?
[07:39:30] <Loetmichel> to verify the io pins in LinuxCNC?
[07:40:14] <gmagno> Loetmichel, you mean for the paralel port, right?
[07:40:21] <Loetmichel> correct
[07:40:54] <Loetmichel> IIRC the normal tb6560 board uses a different pinning as in the youtube video
[07:40:59] <Loetmichel> i have some here ;-)
[07:41:05] <Loetmichel> boards
[07:41:45] <Loetmichel> http://www.youtube.com/watch?feature=player_detailpage&v=oiXjSZ3tIr0#t=6s <- this looks wrong for tb6560-boards
[07:42:21] <gmagno> Loetmichel, I found the pinout, I have some documentation the chineese guys sent me by email :)
[07:42:47] <Loetmichel> so look into your confing if its correct
[07:42:51] <gmagno> gonna check if it corresponds to the settings current settings
[07:42:56] <gmagno> yup
[07:42:59] <gmagno> one sec
[07:48:11] <gmagno> Loetmichel, I'm not sure about some of the pins, for instance, there is one pin that says "All axis enable"... there is no similar function in stepconf pinout configuration :-/any idea which should be?
[07:49:31] <gmagno> should it be "Amplifier Enable"?
[07:50:27] <gmagno> going to try that one
[07:51:03] <gmagno> and I'm going to ignore the Mill to PC signals (limits)
[07:55:37] <gmagno> weird
[07:56:55] <Loetmichel> gmagno: just a moment, booting my cnc
[07:58:04] <gmagno> the motors now emit a sound like TV static. And when I press the button to text the axis they shut up and the board does a CLICK out loud.
[07:58:18] <Loetmichel> hrhr
[07:58:27] <Loetmichel> the clic could be the spindle
[07:58:29] <Loetmichel> relais
[07:58:43] <Loetmichel> the static is a good sign
[07:58:46] <gmagno> right! Let me try it again
[07:58:58] <Loetmichel> its the pulsed current through the motors
[07:59:14] <Loetmichel> sounds more or less like an opened tap
[07:59:17] <Loetmichel> water tap
[08:00:03] <gmagno> Loetmichel, that click is the relays indeed. About the TV static sound do you think it is ok?
[08:00:34] <Loetmichel> yeah
[08:00:46] <Loetmichel> hmm, my stepconf is german
[08:01:06] <Loetmichel> here the enable pin is labeled "endstufe aktivieren"
[08:01:20] <Loetmichel> more or less "enable drivers"
[08:01:51] <gmagno> =D
[08:02:09] <gmagno> that's why I use everything in english :) I'm portuguese
[08:02:28] <Loetmichel> wait a moment, i will boot a linuxcnc-cd in english
[08:02:31] <delkin> ora boas, pessoal
[08:02:34] <gmagno> ok
[08:02:37] <gmagno> boas
[08:02:56] <gmagno> hey delkin, Loetmichel is helping me with our board
[08:03:17] <delkin> that's great, gmagno
[08:03:27] <gmagno> guess what, our paralel port pinout cofiguration was wrong... :P
[08:03:47] <Loetmichel> can you upload a photo of the pinout somewhere?
[08:03:59] <gmagno> Loetmichel, I'm uploading the pdf file
[08:04:02] <Loetmichel> the LPT pinout of the driver board
[08:04:04] <Loetmichel> ok
[08:05:47] <Loetmichel> ok, should be amplifier enable ;-)
[08:06:02] <gmagno> Loetmichel, can you DL this file? http://www.4shared.com/office/u4APYs7v/3_axis_TB6560_english_user_man.html
[08:06:04] <Loetmichel> waiting for the pinout so i can tell you the config
[08:06:13] <gmagno> sry for the delay
[08:06:25] <Loetmichel> no
[08:06:29] <Loetmichel> no login there
[08:08:55] <Loetmichel> sorry
[08:11:57] <gmagno> Loetmichel, sry for the delay once again...
[08:11:59] <gmagno> http://duxe.ru/load/TB6560HQ%20T3%20blue.pdf
[08:12:29] <gmagno> page 7
[08:12:35] <Loetmichel> lokking at it, one moment
[08:20:04] <Loetmichel> gmagno: THAT should work... if you have no limot/home switchecs at the moment: set the switch pins to "unused" -> http://www.cyrom.org/palbum/main.php?g2_itemId=13379
[08:27:16] <gmagno> Loetmichel, I'm using exacly those settings, but the shafts don't move using the test axis window... :-/ Could it be the other parameters problem? Max vel and acce? Would you please look at my stepconf file? http://i.minus.com/1340889303/mGhz2_39jihUPACMgR1EvQ/dbqjIx2zRPRx2V/tb6560.stepconf
[08:30:14] <gmagno> I'm using the following dip switches configuration: "current setting: 50%*2.5A"; "decay: Fast decay"; and "microstepping: 1/2"
[08:32:39] <Loetmichel> just a moment
[08:33:20] <gmagno> sure, ty
[08:35:40] <Loetmichel> hmm, firefoxx crahses...
[08:35:46] <Loetmichel> loading that file...
[08:35:47] <Loetmichel> strange
[08:35:54] <gmagno> =-o
[08:36:39] <gmagno> try this one http://minus.com/mqEpkZ7F8/
[08:37:11] <gmagno> and then click the blue "download" link
[08:38:33] <jdh> what are you going to drive with those tiny motors?
[08:38:47] <Loetmichel> tiny?
[08:38:52] <Loetmichel> theyre BIG ;-)
[08:38:58] <Loetmichel> comparing to my mill
[08:39:04] <Loetmichel> i have 1A motors on mine
[08:39:15] <Loetmichel> sooo
[08:39:57] <Loetmichel> gmagno: does the white noise disappear if you click on "test axis"?
[08:40:01] <gmagno> yup
[08:40:26] <Loetmichel> then try to check the "invert" on pin1
[08:40:33] <gmagno> ok
[08:40:35] <gmagno> one sec
[08:41:50] <gmagno> YEAHHHHHHHHHHHHHHHHHHHHHHHHHHHH
[08:41:53] <gmagno> :)
[08:41:59] <gmagno> it's MOVING!!!!
[08:42:01] <Loetmichel> problem solved ;-)
[08:42:02] <gmagno> EHEHEHEEH
[08:42:07] <gmagno> thanks a lot!!
[08:42:43] <gmagno> :DDDD
[08:42:49] <gmagno> all three are moving
[08:43:36] * Loetmichel had somewhre in memory that the tb6560 uses a low-active Enable ;-)
[08:44:42] <gmagno> ^_^ thanks a lot
[08:44:46] <gmagno> this was eating my brain
[08:44:57] <gmagno> taking my sleep
[08:45:59] <Loetmichel> gmagno: a tip from a user of this drivers: NEVER disconnect a motor when the drivers are powered
[08:46:18] <Loetmichel> or reverse polarity of the supply
[08:46:38] <Loetmichel> will result in this: http://www.cyrom.org/palbum/main.php?g2_itemId=12554
[08:47:36] <gmagno> :D
[08:47:42] <gmagno> thanks for warning
[08:48:32] <Loetmichel> no problem
[08:48:58] <Loetmichel> wasnt TAHT bad, found the problem with the cooling while chanign the driver chips:
[08:49:25] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=12670
[08:50:45] <Loetmichel> jdh: its all in the intended use ofh the mill
[08:50:58] <Loetmichel> MINE can even mill in a cars trunk on a convention...
[08:50:59] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=12691
[08:51:00] <Loetmichel> ;-)
[08:52:15] <Loetmichel> ... or take it to the company and work there... http://www.cyrom.org/palbum/main.php?g2_itemId=12180
[08:56:51] <archivist> jthornton, my last couple of weeks work in reply http://www.archivist.info/apt/aptos/apt360/doc/manual/vocab.html
[09:06:43] <jdh> how do you pronounce hardinge
[09:07:20] <cradek> arrrr-dingie
[09:07:34] <cradek> the h is silent
[09:08:04] <cradek> (but really I have no idea)
[09:08:16] <jdh> heh, that's the 3rd one I've heard (of)
[09:10:26] * Loetmichel imagines cradek with eyepatsch, wooden leg and hook instead of hand ;-)
[09:10:34] <Loetmichel> -s
[09:12:11] <cradek> it's not the leaving of liverpool that grieves me!
[09:16:56] <archivist> we English pronounce the H and the g
[09:17:42] <jdh> har-dinge?
[09:18:11] <archivist> yup
[09:18:47] <Loetmichel> why "ghoti" comes to mind?
[09:18:48] <Loetmichel> ;-)
[09:21:29] <jdh> does APT exist elsewhere?
[09:25:52] <archivist> what do you mean by "exist"
[09:26:09] <jdh> is it still in use anywhere?
[09:26:40] <Loetmichel> on every debian based system?
[09:26:51] <jdh> do any controls use it? Or do things process it to RS274?
[09:26:58] <archivist> different apt Loetmichel
[09:27:04] <Loetmichel> is see now ;-)
[09:27:35] <archivist> apt does not live on controls
[09:28:31] <archivist> the post processor converts the output to gcode for the machine in use
[09:30:36] <jdh> ahh.. I missed that part.
[09:30:37] <archivist> it is still in use in many places, probably mostly aerospace
[10:47:11] <mazafaka> Loetmichel: my workbench^ http://s3.images.drive2.ru/car.journal.photos/x8/3860/000/000/0a4/94e/48cf1f6369553473-large.jpg

[11:07:49] <Pareshchaudhary> engraving with out z ?
[12:05:42] <IchGuckLive> Hi all
[12:07:59] <micges> hi
[12:08:35] <IchGuckLive> micges: can you direct me to the place where the all G5x Zero entry Button is in the Mashine menue
[12:08:39] <IchGuckLive> i cand find it
[12:10:17] <micges> I don't understand
[12:11:47] <IchGuckLive> if been told by -> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?CoordinateSystems#Zero_Coordinate_System tat there is somthing that resets all G5x to zero with a buttonpress
[12:12:12] <IchGuckLive> Zero Coordinate System in the Machine menu its not there
[12:13:23] <IchGuckLive> im on 2.6.0-pre0-3090-g2368c21
[12:15:24] <micges> easiest is to put zeros into var file to parameters 5221 to 5390
[12:15:36] <micges> while emc closed
[12:17:01] <IchGuckLive> i know that but for a teatching lesson its not practical
[12:17:12] <micges> I don't see zero all button
[12:17:27] <IchGuckLive> with 50 people in the classrom
[12:17:43] <IchGuckLive> ok i ask jep
[12:17:52] <IchGuckLive> wher he lost that
[12:18:38] <micges> docs says that there is 9 buttons to zero 9 coord systems
[12:19:32] <IchGuckLive> but thay will then get the current position
[12:19:42] <IchGuckLive> and axis will display them in lines
[12:19:52] <IchGuckLive> so Zero entry woudt be best
[12:45:30] <A0Sheds> hmmm..... still no megawatt Stirling engines for sale
[12:49:16] <A0Sheds> having a difficult time finding lower temp pressure steam turbines as well
[12:49:51] <A0Sheds> I'm starting to think i should make them and then get paid not to sell them by the energy co's
[12:56:38] <IchGuckLive> A0Sheds: in the National museom
[12:58:19] <Loetmichel> oi, the cinese have delivered the ramps1.4 in less than 3 days... somwewhere over ther must be a maildove with burning tail ;-) -> http://www.cyrom.org/palbum/main.php?g2_itemId=13382 ... now i can build a reprap prusa mendel ;-)
[13:05:26] <IchGuckLive> Loetmichel: i recived a Lathe part from Friday 16MESZ to Monday 10MESZ from HK
[13:05:43] <IchGuckLive> 45USD by DHL
[13:07:51] <taiden> afternoon gents
[13:07:57] <IchGuckLive> B)
[13:08:04] <taiden> here to bug you all again :)
[13:08:24] <IchGuckLive> Plese Plese !
[13:08:24] <taiden> what file are the parallel port settings in? Since I added backlash to my ini file I cannot use stepconf to make changes
[13:08:35] <IchGuckLive> HAL
[13:08:38] <taiden> just added spindle control and want to get it working!
[13:10:14] <IchGuckLive> What Spindelcontroller
[13:10:43] <taiden> its just a dc relay for on/off
[13:10:53] <taiden> so not full control sadly!
[13:11:18] <IchGuckLive> yes DC is a miss
[13:11:36] <taiden> ?
[13:11:42] <IchGuckLive> how many ams does the spindel pull
[13:12:11] <IchGuckLive> amps at V
[13:13:42] <IchGuckLive> you can use a full dualbrige for that
[13:14:02] <taiden> it works!
[13:14:17] <IchGuckLive> as a PWM speed control
[13:14:25] <taiden> 5.6a @ 120v
[13:14:31] <taiden> AC
[13:14:40] <taiden> would like a PID controller
[13:14:54] <taiden> would be neat to try to make PID control for emc2
[13:15:28] <taiden> just use a solid state relay connected to my gecko with emc2 outputting pwm with pid logic
[13:15:44] <taiden> not sure if it can handle the frequency required for that though, i dont now much about it
[13:15:58] <IchGuckLive> 18USD at EBAY
[13:16:07] <taiden> for what?
[13:19:44] <IchGuckLive> i misst the speed in the pid its just temp controlled
[13:20:46] <IchGuckLive> by im off
[13:25:33] <taiden> I wish my german was better
[13:26:24] <mrsun> wth, you need to anneal a clay graphite crucible? :)
[13:27:04] <syyl_ws_> ah, mrsun :D
[13:27:13] <mrsun> what? :P
[13:27:24] <syyl_ws_> made some models today
[13:27:26] <syyl_ws_> for casting
[13:27:27] <syyl_ws_> :)
[13:27:41] <mrsun> =)
[13:27:53] * mrsun does not like his country, impossible to find stuff in it :/
[13:28:00] <mrsun> like clay graphite crucibles :P
[13:28:00] <syyl_ws_> https://dl.dropbox.com/u/24396704/2012-06-27_15-08-13_308.jpg
[13:28:24] <syyl_ws_> i went the easy way, machining them from solid--
[13:28:40] <syyl_ws_> http://www.youtube.com/watch?v=WGv_PrD4WdM
[13:28:47] <syyl_ws_> kind a mess ;)
[13:29:16] <mrsun> machinable waz?
[13:29:19] <mrsun> wax
[13:30:02] <syyl_ws_> renshape highdensity polyurethane foam
[13:30:03] <syyl_ws_> :)
[13:30:16] <syyl_ws_> especialy for model making
[13:30:19] <mrsun> your camera does wacky stuff :P
[13:30:43] <mrsun> either that or your machine is made of rubber :P
[13:30:50] <syyl_ws_> ah, thats the anti-shaking feature of youtube
[13:30:58] <syyl_ws_> i will undo that
[13:31:01] <mrsun> hehe =)
[13:31:02] <mrsun> ok =)
[13:31:11] <mrsun> nice patterns =)
[13:31:18] <mrsun> i should use the mill more for patterns
[13:31:28] <mrsun> hell even got a 1.5 degree endmill for the purpouse =)
[13:31:43] <syyl_ws_> uh, nice :)
[13:31:49] <syyl_ws_> thats what i am still missing
[13:31:59] <syyl_ws_> but these days its pretty hard to get
[13:32:03] <syyl_ws_> them
[13:32:52] <mrsun> syyl_ws_, china ... :P
[13:32:55] <mrsun> ctctools.biz
[13:33:50] * syyl_ws_ backs off
[13:33:53] <syyl_ws_> no way :D
[13:34:27] <mrsun> omg
[13:34:38] <mrsun> far bellow half the price in sweden to freakin buy it from the uk
[13:35:34] <mrsun> but to high weight to buy 4 of them :P
[13:35:36] <andypugh> I also have some tapered cutters from ctctools.biz I find they offer a very good service if you can wait a week.
[13:36:52] <mrsun> ive bought alot of stuff there, and havent been disapointed in more then the carbide scribe that is like a pen they have ... broke in the second click :p
[13:39:06] <andypugh> syyl_: Where do you get your HDPE foam board from? I can only find it in large lumps. priced to match
[13:39:18] <syyl_ws_> we get it sheetwise...
[13:39:32] <syyl_ws_> about 1200x600mm or so
[13:39:38] <andypugh> Ah. I think someone ought to sell hobby-sized lumps on that eBay
[13:40:00] <syyl_ws_> i use scrap pieces for my specialprojects.. :D
[13:42:15] <mrsun> BAAH THEY HAVE EVERYTHING ABROAD
[13:42:18] <mrsun> ffs :/
[13:42:28] <mrsun> insulating firebricks, clay graphite crucibles to a reasonable price
[13:42:35] <syyl_ws_> oh
[13:42:52] <mrsun> but hey. .. i live in freakin sweden where bad weather and mosquitos is the song and not a single company sells fun stuff :/
[13:44:01] <mrsun> not even the smallest crucible i can buy aparently
[13:44:07] <mrsun> cause weight is to high ... wth
[13:44:17] <archivist> start an interesting parts company
[13:45:42] <mrsun> im starting to think i will have to become an importer of stuff and sell it online in sweden, this is redicilous .. finding one company in sweden that sells crucibles, but tehy are double the price in the uk and they only got small ones
[13:46:46] <mrsun> but ofc, they are targeted to like jewlery making also
[13:48:51] <andypugh> mrsun: In the UK, I know, but this place looks useful: http://www.johnwinter.co.uk/model-engineering/model-engineering
[13:56:51] <mrsun> Please note: If you get the message "Goods are too heavy" you are probably trying to buy online for an overseas destination which this site does not cater for. In such instances please email us
[13:56:53] <mrsun> ahh there =)
[13:57:07] <mrsun> guess i have to mail them then .. and hope the shipment wouldnt be to bad
[13:57:13] <mrsun> and its inside the eu .. no tolls :P
[13:58:18] <mrsun> wth the prices are sick
[13:58:32] <mrsun> £15 for 1600 degree castable refractory at 25kg bags?!"
[13:58:43] <mrsun> i have to give like 10 times that here :/
[13:58:51] <syyl_> sand?
[13:59:31] <archivist> pay my diesel money and I will bring a car load
[14:00:05] <mrsun> archivist, haha :P
[14:00:09] <archivist> +expenses :)
[14:00:20] <mrsun> right, how much can your car carry ? :P
[14:00:43] <mrsun> washington dc ?
[14:00:52] <mrsun> that will be an expensive round trip :öp
[14:01:20] <andypugh> I thought you were in Sweden?
[14:01:25] <archivist> he is
[14:01:42] <mrsun> but archivist isnt :P
[14:01:51] <andypugh> Nor is he in Wshinton DC
[14:02:06] <mrsun> oh
[14:02:10] <mrsun> whois said so :P
[14:02:17] <mrsun> lol
[14:02:20] <mrsun> thats the freenode server
[14:02:21] <mrsun> haha
[14:02:29] <archivist> I did a little trip sunday afternoon after fitting the wheel bearing...332 miles
[14:03:01] <mrsun> 534km .... that wouldnt cut it to get here i guess :P
[14:03:33] <andypugh> Hmm, John Winter are 12 miles from my parents. COuld be handy
[14:03:44] <archivist> speaking of which.. wheel bearings look like a cheap ballscrew end bearing
[14:04:12] <mrsun> compact bearings i guess is the same thing
[14:04:22] <mrsun> two angular contact bearings
[14:04:48] <archivist> mine has a common outer but yes
[14:04:49] <andypugh> Yes, I looked at them a while back because they come in some odd sizes.
[14:04:59] <mrsun> archivist, yes, common outer, divided inner
[14:05:17] <mrsun> two angular contact bearings that is spaces as they should :P
[14:05:33] <archivist> and the price is right ish
[14:05:47] <andypugh> Especially if you work for a car company.
[14:05:56] <mrsun> http://image.made-in-china.com/2f0j00reltVnKsAhoz/Automobile-Wheel-Bearing.jpg those right? :)
[14:06:42] <archivist> yes mine looked similar
[14:06:43] <mrsun> no its roller bearings in them :P
[14:06:52] <mrsun> or angular contact
[14:07:00] <mrsun> heh, comes in two types
[14:07:07] <mrsun> http://image.made-in-china.com/2f0j00YRztWcaGDEKp/Double-Row-Angular-Contact-Bearing-for-Wheel-Hub-One-Generation.jpg
[14:07:43] <archivist> this being the part I used fleabay 170775839455
[14:07:44] <mrsun> i wonder how rigid they are .. thinking spindle bearing :P
[14:08:35] <archivist> for a spindle one may want to remove the seal for less friction
[14:09:06] <mrsun> tho they arent adjustable :/
[14:10:15] <archivist> I assume they will preload when done up tight, so no adjustment needed
[14:10:32] <mrsun> archivist, yeah but when they wear then ? :)
[14:10:33] <archivist> does mean good press fits etc
[14:14:55] <Jymmm> I really don't know how useful this information is to anyone, but 1" 8020 extrusion fits perfectly at a 45 degree angle into a 0.125" thick wall 0.750" wide aluminum C-Channel... http://i46.tinypic.com/2l9456s.jpg http://i50.tinypic.com/xwtxw.jpg http://i49.tinypic.com/28vaej6.jpg http://i50.tinypic.com/2illnog.jpg
[14:15:55] <Jymmm> with maybe a 0.020" play
[14:21:19] <mrsun> finaly found a company in sweden that actualy sells graphite crucibles =)
[14:25:22] <mrsun> but like usual, no webshop so have to call or email
[15:30:22] <JT-Shop> I need a small cost effective servo with a dumb drive... any clues where to look?
[15:31:32] <cradek> very old hp inkjet printers/plotters (original deskjet, old designjet)
[15:47:35] <JT-Shop> thanks, I should have said something about needing off the shelf that I can buy as many as I want
[15:48:51] <archivist> and what size you need :)
[15:54:59] <Tom_itx> someone posted a link to a servo here maybe a week or two ago that looked rather appealing but i don't have the link handy
[15:55:59] <Tom_itx> NEMA size 23 iirc
[15:58:56] <Loetmichel> *grrr*... me looks on the calendar: is it REALLY not monday? literally 1000s of screwdriver bits... and have to search half an hour for the ONE PZ2 bit left... and then: battery drill empty after the second screw... :-(
[16:02:10] <archivist> next time get a box of 50 pz2 bits
[16:02:30] <archivist> then all the missing ones will reappear
[16:07:04] <Loetmichel> archivist: thats likeley to happen ;)
[16:07:18] <andypugh> JT what sort of torque/power?
[16:08:24] <andypugh> Jon has some: http://pico-systems.com/osc2.5/catalog/product_info.php?products_id=27
[16:08:32] <archivist> Loetmichel, I spent half a day or more a week ago putting all the bits back into the original sets
[16:08:34] <Tom_itx> http://www.servo-drive.com/servomotors_servodrive_servomotors.php
[16:09:20] <Loetmichel> <- quickcharging the drill... thank god for the model computer charger ;-)
[16:10:51] <JT-Shop> something along the torque you get from a 7.2v cordless
[16:10:59] <Tom_itx> http://www.automationtechnologiesinc.com/products-page/nema23-m-dc-servo-motor
[16:11:08] <andypugh> How about a 7.2V cordless?
[16:11:09] <Tom_itx> $60
[16:11:32] <JT-Shop> it has to run all day long for a long time
[16:11:43] <JT-Shop> and I need encoder feedback
[16:11:54] <Tom_itx> AC or DC?
[16:12:07] <JT-Shop> doesn't matter
[16:12:11] <JT-Shop> at this point
[16:12:18] <Tom_itx> ^^
[16:13:22] <Tom_itx> about $100 by the time you add the encoder
[16:15:00] <DJ9DJ> gn8
[16:15:41] <JT-Shop> Tom_itx: yea something like that
[16:15:53] <JT-Shop> what does skewed rotor mean?
[16:16:05] <Tom_itx> the rotor shims are skewed
[16:16:10] <Tom_itx> not straight across
[16:16:23] <JT-Shop> what does that do?
[16:16:33] <Tom_itx> beats the hell outta me.
[16:16:39] <Tom_itx> it smooths the torque?
[16:16:44] <JT-Shop> lol me too
[16:16:52] <Tom_itx> i think that's what it does
[16:17:17] <andypugh> Reduces cogging.
[16:17:32] <JT-Shop> lol it is a keling motor
[16:17:44] <Tom_itx> well that just figures
[16:17:58] <Tom_itx> i bet i could put you in contact with a china source i have
[16:18:17] <andypugh> If you go to Kelininc.com it says "please visit out now web site, automationtechnolgies….
[16:18:37] <Tom_itx> oh yeah i got a notice about that the other day
[16:18:47] <Tom_itx> didn't really register with me though
[16:19:11] <JT-Shop> ok, it is there new web site then
[16:20:01] <JT-Shop> the other part of the puzzle is I need to be able to just tell it to turn 3 times or some degrees of turn... real simple commands
[16:21:20] <andypugh> JT-Shop: WillemCMD id playing a simlar game. He is using HAL and a GaldeVCP GUI, but not the rest of LinuxCNC
[16:22:06] <JT-Shop> I actually want to get lower level than that and not have a pc at all in the loop
[16:22:07] <andypugh> So, Glade button sends target position to Limit3 component drives PID or Stepgen. Second button sets the tarhet positin back to home.
[16:22:08] <andypugh> ]
[16:22:11] <JT-Shop> any ideas?
[16:22:27] <andypugh> You said you wanted a dumb drive.
[16:22:40] <andypugh> Sounds like a job for a semi-smart drive.
[16:23:32] <andypugh> My experience has been that when you try to take a PC out of a system the alternatives cost more, and are a lot more difficult to reconfigure when the customer changes their mind.
[16:23:48] <Tom_itx> hmm somebody that makes those smart drives got one of my programmers.. i can't remember who it was now
[16:24:03] <andypugh> Paybe have a word with that spammer on the Forum. His PC is very tiny,
[16:24:28] <andypugh> The answer is probably an Arduino. It normally is.
[16:24:50] <JT-Shop> I was kinda thinking that the Arduino was a key part
[16:26:15] <andypugh> http://www.ebay.co.uk/itm/390431979950 (just saw it, not an answer to this question)
[16:28:09] <andypugh> The answer to the question might be the DMM-tech drive/motor combo with step-dir command from the Arduino: http://www.dmm-tech.com
[16:29:48] <andypugh> Prices are at the lower end: http://www.dmm-tech.com/Files/DMMTechnology_pricelist_Rev.1.2.pdf
[16:31:27] * JT-Shop looking
[16:40:49] <Tom_itx> JT-Shop, do you have any specs on your servo motor?
[16:41:30] <JT-Shop> no, I'm just at the guess stage
[16:41:50] <Tom_itx> that guy in china may have a source if you need several
[16:42:27] <Tom_itx> he found an mpg for me but i'd already gotten one
[16:43:30] <Tom_itx> i got my last batch of pcbs from him
[16:48:17] <andypugh> JT-Shop: Another alternative might be a Mesa card running SoftDMC rather than Hostmot2.
[16:58:46] <JT-Shop> andypugh: thanks
[16:59:11] <andypugh> For which bit?
[17:02:13] <JT-Shop> SoftDMC
[17:05:23] <Tom_itx> what's this crazy double barrel cannon i see on pawn stars
[17:05:37] * Tom_itx thinks JT-Shop may need one of those
[17:07:36] <JT-Shop> got 3 cannons now in the shop, don't need any more!
[17:09:22] <Loetmichel> Tom_itx: cannon? or do you mean the 2011 .45?
[17:10:04] <Tom_itx> it was a cannon
[17:10:23] <Loetmichel> http://www.youtube.com/watch?v=BM-DGaNmtA0 <- found that extremly useless
[17:14:02] <Tom_itx> http://www.youtube.com/watch?v=6133INUwLuE&feature=related
[17:14:10] <Tom_itx> may not be the same one but similar
[17:15:20] <uw> lol still pointing north
[17:32:54] <andypugh> I guess if it has a common "combustion chamber" then timing the balls wouldn't be quite as hard.
[17:50:28] <r00t4rd3d> im getting me a Nexus 7
[17:50:49] <r00t4rd3d> google, asus, nvidia = 199
[18:28:03] <andypugh> Night all
[18:28:14] <Jymmm> nite andypugh
[18:50:17] <r00t4rd3d> have horrible dreams!
[19:21:34] <ds3> o
[19:23:49] <Jymmm> k
[19:24:02] <Tom_itx> d o k i e
[19:25:59] <r00t4rd3d> http://www.kickstarter.com/projects/lehoux/the-kinkajou-a-bottle-cutter-with-a-new-twist
[19:27:37] <tjb1> Do inductors have a polarity?
[19:28:17] <Tom_itx> the earth does
[19:29:01] <Tom_itx> not that i know of
[19:29:10] <tjb1> One leg is longer, just wondering
[19:29:20] <Tom_itx> well so are mine
[19:29:22] <Tom_itx> :)
[19:29:43] <tjb1> ha alright
[19:32:30] <tronwizard> inductors have no polarity
[19:32:52] <tjb1> Thanks
[19:33:02] <tronwizard> but sometimes phasing matters if you're coupling to another inductor
[19:33:13] <Tom_itx> definitely
[19:33:42] <Tom_itx> i coupled 3 transformers primaries AND secondaries to make the psu for my mill
[19:34:23] <tronwizard> weird voltage requirement?
[19:34:23] <Tom_itx> there was less than 35ma direct short between the secondaries if anyone is gonna tell me i'm nuts
[19:34:29] <tronwizard> or just 120 to 240
[19:34:30] <Tom_itx> surplus
[19:34:37] <Tom_itx> 50v 18A
[19:34:52] <tjb1> Is there is nothing in the datasheet, is the top of the diagram always the dot on a chip
[19:35:00] <tjb1> or is the dot pin 1?
[19:35:20] <tronwizard> usually
[19:35:36] <Tom_itx> tronwizard, mostly surplus except the mesa and gecko stuff: http://tom-itx.dyndns.org:81/~webpage/cnc/psu/control5.jpg
[19:35:52] <tronwizard> wow
[19:35:55] <Tom_itx> including the box
[19:36:29] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/cnc/psu/psu_index.php
[19:36:32] <Tom_itx> project page
[19:36:43] <tronwizard> looks a little tight to work on but the layout is nice
[19:37:36] <Tom_itx> i wanted a little bigger box but for $22 and shipping....
[19:38:18] <tronwizard> you have any trouble with coupling between those xfmrs because they're all oriented the same?
[19:39:02] <Tom_itx> not really
[19:39:26] <Tom_itx> i originally coupled them after the dc bridges
[19:40:47] <Tom_itx> all that's left is to wire up the pendant
[19:40:50] <tronwizard> oooo, nice etch tank
[19:41:47] <Tom_itx> yeah i've done a bit of that too
[19:43:56] <tjb1> White stripe on cap negative?
[19:44:02] <Tom_itx> yup
[19:44:21] <Tom_itx> flip a coin
[21:57:54] <tjb1> Tom_itx:
[21:59:51] <Tom_itx> ?

[22:12:07] <tjb1> http://psi.abcom.co.nz/circuit10.jpg
[22:12:22] <tjb1> the iso amp is at 3.6v between vdd2 and vout+
[22:12:25] <tjb1> is something wrong
[22:12:32] <tjb1> or do I need to add stuff to it
[22:18:24] <Tom_itx> not sure what you got going on there
[22:18:37] <tjb1> Well the output was wrong
[22:18:43] <tjb1> so i pulled the iso amp and put it on the breadboard alone
[22:18:57] <tjb1> and it seems it is bleeding voltage between VDD2 and VOut+
[22:19:04] <Tom_itx> generally the data sheet will have design suggestions
[22:19:26] <Tom_itx> breadboarding stuff isn't the most reliable way
[22:19:35] <Tom_itx> breadboards suck electrically
[22:20:17] <tjb1> well I soldered it all together and it didnt work
[22:20:18] <tjb1> :P
[22:20:37] <tjb1> http://www.digikey.com/scripts/DkSearch/dksus.dll?vendor=0&keywords=ACPL-782T-000E
[22:20:39] <tjb1> there is the iso amp
[22:21:04] <Tom_itx> what's this for?
[22:21:12] <tjb1> to measure plasma cutter voltage
[22:21:26] <Tom_itx> oh
[22:22:21] <tjb1> Something wrong with iso amp or am I missing some pieces?
[22:27:53] <Tom_itx> you may need more gain on the output of the opto
[22:27:56] <Tom_itx> i'm not sure
[22:28:27] <tjb1> more gain?
[22:28:37] <Tom_itx> op amp
[22:30:02] <Tom_itx> holy crap those are expensive
[22:30:11] <tjb1> Yeah lol
[22:32:25] <uw> r00t4rd3d, have you used that before?
[22:33:34] <Tom_itx> tjb1, did you see the recomended board layout for that?
[22:33:42] <tjb1> What page?
[22:33:43] <Tom_itx> you may not get good results on a breadboard
[22:33:49] <tjb1> Dont say 16
[22:33:55] <Tom_itx> 14
[22:34:12] <Tom_itx> and 16
[22:34:14] <Tom_itx> :)
[22:34:25] <tjb1> So…I need all of that past 6 and 7
[22:34:48] <Tom_itx> that would be the op amp i mentioned
[22:35:07] <tjb1> So that would eliminate the voltage between 7 and 8
[22:35:26] <Tom_itx> i don't know
[22:35:40] <Tom_itx> i've not used that part or tried to design such a circuit
[22:35:51] <tjb1> Well what do you think about just hooking arduino ground to the plasma -
[22:36:33] <tjb1> Because I dont feel like spending any more money on this stupid circuit
[22:36:34] <Tom_itx> it should have a common ground
[22:36:48] <tjb1> It does, but it doesnt share with the voltage output
[22:38:26] <tjb1> Im just gonna ground the damn thing
[22:38:32] <tjb1> If I blow the arduin up its only $20
[22:38:41] <tjb1> already wasted $30 on this stupid ass circuit
[22:38:51] <Tom_itx> no reason to blow it now
[22:39:05] <Tom_itx> i just don't know what it's supposed to do or how the part works
[22:39:10] <tjb1> Well
[22:39:18] <uw> lol oh i remember this circuit
[22:39:20] <tjb1> Thats suppose to isolate the voltage divider on the plasma cutter
[22:39:24] <tjb1> from the arduino...
[22:39:38] <tjb1> and the dc/dc isolates the power from the arduino
[22:39:42] <tjb1> sounds good in theory
[22:39:44] <uw> where did you get this thing anyway?
[22:39:44] <tjb1> but yeah.
[22:39:57] <tjb1> sparkfun irc.
[22:40:08] <tjb1> some guy on eevblog added all the stuff in red
[22:40:26] <Tom_itx> time to sleep for me
[22:40:33] <uw> good night Tom_itx
[22:40:38] <Tom_itx> don't give up on it just yet
[22:40:38] <tjb1> Bye Tom_itx
[22:40:49] <tjb1> Well tomorrow morning im hooking arduino up to plasma cutter
[22:41:09] <Tom_itx> if it's not 5v it won't like it
[22:41:22] <tjb1> The guy who made it was bitching because I soldered it so I isolated the iso amp and its still not working
[22:41:26] <tjb1> I have a voltage divider
[22:41:41] <Tom_itx> what's the voltage you're trying to monitor?
[22:41:56] <tjb1> 7
[22:42:03] <tjb1> but I have a voltage divider to bring it down to 5
[22:42:19] <Tom_itx> and what's the voltage swing of it?
[22:42:29] <tjb1> 0-7
[22:42:30] <Tom_itx> ground to 5v?
[22:42:45] <tjb1> ?
[22:43:58] <Tom_L> well that sucked
[22:44:12] <Tom_itx> zlog
[22:45:31] <Tom_itx> measure the voltage with a meter on your voltage divider
[22:46:30] <tjb1> Well with no arc is 0
[22:46:39] <tjb1> arc depending on stuff it varies
[22:47:20] <Tom_itx> so what makes it vary?
[22:47:36] <tjb1> distance from work piece to tip
[22:47:40] <tjb1> longer distance = higher voltage
[22:48:00] <Tom_itx> with the max at 5v
[22:48:17] <tjb1> With my voltage divider it will max at 5v because the max input on the arduino is 5v
[22:48:37] <Tom_itx> ok, did you set the adc reference to 5v?
[22:49:06] <tjb1> are we talking about the iso amp or the arduino?
[22:49:30] <Tom_itx> the arduino
[22:49:39] <Tom_itx> you said you were gonna hook it up directly
[22:49:43] <tjb1> Well I havent got to the arduino yet
[22:49:56] <tjb1> Why do I need the analog reference at 5v?
[22:50:17] <Tom_itx> well because that's the voltage you want to measure
[22:50:29] <tjb1> well the arduino max is 5v
[22:50:32] <tjb1> so 5v is 1023 anyway
[22:50:44] <tjb1> So I wouldnt need a reference
[22:51:07] <Tom_itx> where are avcc and aref pins tied?
[22:51:23] <Tom_itx> and agnd
[22:51:46] <tjb1> No aref
[22:51:56] <tjb1> there is analog input
[22:52:00] <Tom_itx> well there needs to be
[22:52:18] <Tom_itx> because that sets the reference voltage for the adc pins
[22:52:20] <tjb1> I dont need a reference if I am working with 5v
[22:52:32] <Tom_itx> so tie it to 5v then
[22:52:52] <Tom_itx> aref needs to be tied to something unless you're using an internal reference voltage
[22:53:00] <tjb1> its internal
[22:53:02] <tjb1> it will use 5v
[22:53:18] <tjb1> unless changed by the aref
[22:53:47] <Tom_itx> so hook it up and try it then
[22:54:14] <tjb1> Its 11:43 :P
[22:54:21] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/how_to/atmega168/mega168_adc_index.php
[22:54:50] <tjb1> Every time I screw with electronics, I waste money
[22:55:06] <tjb1> I wasted more money trying to build a "Drawdio" then it would of cost to buy the damn kit
[22:55:32] <Tom_itx> well if you don't know what you're doing maybe the kit would be the best bet
[22:56:58] <tjb1> Im just gonna hook the arduino up tomorrow
[22:57:00] <tjb1> if it blows
[22:57:07] <tjb1> Ill buy a new arduino and save up $600 for the thc
[22:57:35] <Tom_itx> all you'd need would be another mega328
[22:57:38] <Tom_itx> probably
[22:57:46] <Tom_itx> and those are cheap
[22:57:56] <tjb1> yeah like $4 with the bootloader on it
[22:58:13] <Tom_itx> poop on the bootloader
[22:58:17] <Tom_itx> i'm not sold on arduinos
[22:58:26] <tjb1> Well im stupid
[22:58:31] <tjb1> So you see why I use it
[22:58:37] <Tom_itx> the boards are ok but i don't like their libs etc
[22:58:47] <tjb1> I cant stand programming it
[22:58:51] <Tom_itx> because you don't know what you got
[22:58:51] <tjb1> like Serial.print
[22:58:58] <tjb1> It doesnt work if you use serial.print
[22:59:03] <tjb1> or Serial.Print
[22:59:14] <jdh> nor should it.
[22:59:29] <tjb1> I cant stand the case sensitive programming
[22:59:47] <jdh> like c?
[22:59:57] <Tom_itx> gnite
[23:00:26] <tjb1> Bye Tom_itx
[23:00:32] <tjb1> Ill let you know how many chips blow up
[23:01:02] <Tom_itx> 0
[23:01:18] <tjb1> Too bad you cant return stuff to digikey
[23:01:24] <tjb1> $30 learning experience...
[23:01:31] <tjb1> jdh, I cant learn programming
[23:03:19] <tjb1> Well the DC/DC isolator works…guess I could find a use for that
[23:04:23] <tjb1> jdh you experienced with electronics?
[23:04:24] <tjb1> I have an idea.
[23:10:57] <taiden> so who wants to look at my gcode and critique my methods?
[23:11:11] <taiden> code runs fine but im trying to write better code
[23:12:26] <tjb1> http://sphotos.xx.fbcdn.net/hphotos-ash3/s480x480/529211_3978241010417_281095656_n.jpg
[23:12:39] <tjb1> Sorry Tainden, I havent done g-code in a while
[23:12:43] <tjb1> *Taiden
