[01:56:58] <DJ9DJ> moin
[01:57:01] <DJ9DJ> hola Jymmm
[01:57:10] <Jymmm> howdy
[01:59:48] <skorket> anyone still up?
[01:59:57] <archivist> no
[02:01:03] <archivist> the world is round, there is always someone "up" just ask the real question in irc
[02:38:03] <skorket> archivist, most people are based in the US
[02:40:07] <skorket> I'm very new and I only have a passing familiarity with what feed rates are, chip load is, etc. I would like to just get a sense for what it would take to cut aluminum. I have a 8k spindle. Does anyone have a suggestion on what bit to use and how fast the bit should move relative to the table?
[03:00:43] <archivist> it does amuse one that americans think they are centre of the universe
[03:02:00] <archivist> aluminium is best machined with cutter profile ground for aluminium and the right lubrication
[03:03:45] <archivist> there are a number of online calculators for speeds and feeds
[03:04:39] <archivist> often what is best for the material cannot be achieved due to light weight of the machine
[03:19:52] <DJ9DJ> yeah, you need an infinite strong machine with infinite speeds and interial dampers! ;)
[03:20:53] <DJ9DJ> *inertial
[03:55:47] <skorket> I would really appreciate any suggestions, even a case study, of someone who has done some aluminum milling. I'm not sure I'm using the online calculators correctly and I'm not even sure what questions to be asking.
[03:56:06] <skorket> I was hoping someone could tell me 'this is my setup, I know this works'
[04:14:33] <Loetmichel> mornin
[04:14:40] <archivist> skorket, there is generally no one answer, but the chip cut per tooth at an rpm gives you the feed rate
[04:16:34] <archivist> skorket, the Sandvik data book on cutting(pdf on their site) gives some real world examples but are generally at the top end that amateurs can achieve
[04:18:16] <archivist> also learn about "built up edge" the metal sticks to the cutter causing finish and dimension problems, lubrication helps as does cutter form
[04:19:16] <archivist> climb milling being best but is your machine good enough for climb milling
[04:21:02] <archivist> one gains experience on ones machines and you will find different alloys machine differently, hard v soft pure aluminium
[04:26:50] <archivist> and the other thing to take into account is the work piece and its clamping, light v heavy cuts, once you have a few escape and break cutter you will learn the importance of good clamping
[04:37:48] * Jymmm is lucky enugh to have only broke one tool
[04:38:32] <Jymmm> Note to self: Verify that when you hit the home button, that it actually homes.
[05:08:28] <Loetmichel> *yuck* $me has just cleaned out the grinder of my saeco. SOMEONE must have put water in the grinder. the coffee powder was like concrete... and the machine isnt really serviceable, i had to dismantle half of it to get to the grinder :-(
[06:17:37] <jthornton> skorket, what kind of machine do you have?
[06:26:31] * jthornton thinks there is not much that is more exciting than watching the material get pulled into the cutter when you didn't tighten the vise properly
[06:37:45] <Tom_itx> morning jthornton
[06:46:12] <jthornton> morning Tom_itx
[06:52:58] <archivist> jthornton, or 20lbs of work thrown off the horizontal when cutting forces eventually vibrate the work loose and the cutter grabs it and throws it
[06:53:31] <archivist> I wonder if that is why the spindle is not exactly straight :)
[06:54:08] <jthornton> my favorite is a bit smaller when a parallel shoots out of the vise when you drill too close to it
[06:55:34] <archivist> I was just using the horizontal as a saw :)
[06:57:04] <archivist> because the metal was bent I had it up on blocks and very long bolts and the table is nver wide enough to clamp properly is it !
[06:58:38] <jthornton> that sounds exciting
[07:02:09] <archivist> milling sheet and cutter rake lifting it up
[07:02:26] <Tom_itx> yeah i shoved some metal out the back of a vmc once
[07:02:27] <archivist> another thing to bite noobs
[07:03:00] <archivist> one needs an accident to learn the frailties
[07:03:13] <Tom_itx> was flycutting a stack of test specimens when someone came up and was distracting me. i forgot to tighten the vice up on the material
[07:03:32] <jthornton> I see Peter has added DIN rail clips for the daughter cards!
[07:04:57] <Tom_itx> 5" shell mill makes a pretty good projectile launcher
[07:07:07] <archivist> chucks coming unscrewed when you stop a lathe too
[08:42:28] <gmagno> Good afternoon
[08:45:50] <gmagno> I'm trying to understand the concept of roughing offset in "image_to_gcode" but I'm not sure I undertsand it. You guys have a different (from http://www.linuxcnc.org/docs/2.4/html/gui_image-to-gcode.html#r1_4_19) way of defining it?
[08:54:04] <r00t4rd3d> its how close it will cut to the final part
[08:55:38] <r00t4rd3d> a roughing pass is what you do before a finish pass
[08:56:54] <r00t4rd3d> so if your roughing offset is 0.1 it will only cut to within 0.1 of your finish pass
[09:01:49] <gmagno> r00t4rd3d, so, if I choose a roughing offset of 0.0, the last pass should be at the exact depth parameter, right?
[09:03:30] <r00t4rd3d> you dont want to use 0.0 or your finish pass will have nothing to cut
[09:04:32] <gmagno> if I choose a roughing pass of 0.1, a max depth of 1.0, and a roughing offset of 0.0, it should do 10 passes, right?
[09:05:26] <r00t4rd3d> for one line
[09:05:40] <gmagno> for one line?
[09:05:46] <gmagno> what do you mean
[09:06:25] <r00t4rd3d> yeah it would do ten passes at 0.1inch
[09:07:04] <r00t4rd3d> err wait
[09:07:10] <r00t4rd3d> 0.1 is inches
[09:07:17] <gmagno> but is there anything I'm missing? Because I would only need two parameters for this, roughing pass and max depth
[09:07:18] <r00t4rd3d> so how many ever 0.1 = an inch
[09:07:55] <r00t4rd3d> ten 0.1 doesnt equal and inch , 1.0
[09:08:05] <JT-Shop> while trying to install simulator. The package installer comes up with message
[09:08:05] <JT-Shop> Error: Cannot install 'python-imaging-tk'.
[09:08:10] <gmagno> :-o what
[09:08:18] <JT-Shop> anyone know what that means?
[09:08:38] <r00t4rd3d> s/and/an
[09:10:20] <gmagno> r00t4rd3d, how come 10x0.1 != 1 ??
[09:10:45] <r00t4rd3d> cause its measurement, not counting
[09:12:09] <gmagno> ok, there must be something really fundamental that I'm missing here, because I'm completely lost (OR you don't know what you're saying :P)
[09:12:20] <r00t4rd3d> that may be true
[09:12:26] <gmagno> which one? :D
[09:12:55] <gmagno> ok, let's thing together
[09:12:59] <gmagno> think*
[09:14:23] <r00t4rd3d> does 10 passes at 0.1inch equal 1.0inch ?
[09:14:25] <r00t4rd3d> who knows
[09:14:28] <r00t4rd3d> i dont think so
[09:15:22] <r00t4rd3d> maybe it does, try it
[09:15:28] <gmagno> wait
[09:15:40] <gmagno> what does 1 pass of 0.1inch equals to?
[09:15:48] <gmagno> 0.1, right?
[09:16:03] <gmagno> (this is becoming ridiculous)
[09:16:05] <gmagno> :D
[09:16:13] <r00t4rd3d> yeah which is almost an 1/8th of an inch
[09:16:24] <r00t4rd3d> 0.125 = 1/8 of an inch
[09:16:45] <gmagno> no, it's 1/10th
[09:16:53] <gmagno> it's 0.1
[09:17:12] <r00t4rd3d> *almost*
[09:17:20] <r00t4rd3d> im done.
[09:17:28] <r00t4rd3d> stick a fork in me
[09:17:37] <gmagno> :D
[09:17:47] <r00t4rd3d> image to gcode sucks anyway
[09:17:54] <gmagno> I think we both need some rest
[09:18:03] <r00t4rd3d> you will soon realize that
[09:18:13] <r00t4rd3d> for simple stuff, okay
[09:18:23] <gmagno> why is that?
[09:19:52] <r00t4rd3d> if it interprets it wrong, you have no way of correcting it.
[09:19:57] <r00t4rd3d> no way to scale it
[09:20:04] <r00t4rd3d> no way to preview it
[09:20:11] <r00t4rd3d> no way to change your tool
[09:20:45] <r00t4rd3d> it is extremely basic
[09:23:33] <r00t4rd3d> i can use vector magic and cut2d and see exactly what my image will look like, can edit the nodes, change my tool, preview my cuts
[09:27:55] <gmagno> i see
[09:28:15] <gmagno> I'll give image_to_gcode a try
[09:42:29] <gmagno> is there a way of changing feedrate whilemachine already performing work
[09:42:31] <gmagno> ?
[09:42:44] <gmagno> there is a feed override
[09:42:50] <gmagno> but I want more than 120%
[09:43:17] <gmagno> I'm figuring that this will take an eternity... :P
[09:44:11] <gmagno> 7mins have passed and still in 25% of the FIRST pass...

[09:54:10] <jp__> morn
[10:04:53] <JT-Shop> morning
[10:10:33] <joe9> is it possible to run linuxcnc simulation on a machine without rtai installed? and with a linux kernel 3.4.6?
[10:10:56] <DJ9DJ> at least with 3.2.0-29 it works :)
[10:11:21] <joe9> DJ9DJ: did you have to do anything special/different to get it installed?
[10:11:53] <DJ9DJ> hm, i downloaded a special simulation package
[10:12:10] <ReadError> i just threw linuxcnc on my vmware esxi box
[10:12:11] <DJ9DJ> the file is called linuxcnc-sim_2.5.0_amd64.deb on my hard drive...
[10:12:23] <joe9> DJ9DJ: ok, thanks.
[10:12:29] <joe9> ReadError: will check that out.
[10:13:12] <DJ9DJ> dont remember any special points, but i created/adapted the simulation hal configuration for my machine extends
[10:13:34] <DJ9DJ> joe9: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?action=browse&diff=1&id=LinuxCNC_Pure_Simulator
[10:14:17] <joe9> DJ9DJ: ok, thanks a lot.
[10:14:36] <DJ9DJ> good luck
[10:16:19] <DJ9DJ> you have to look if you need 32-bit (i386) or 64-bit support (amd64)
[10:16:32] <joe9> i need 64 bit for this machine.
[10:16:53] <DJ9DJ> ok
[10:20:02] <JT-Shop> joe9: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?LinuxCNC_Pure_Simulator
[10:22:33] <DJ9DJ> yeah thats the right page :)
[10:30:00] <jp__> JT-Shop: did the files i sent work for you?
[10:37:05] <JT-Shop> when did you send them?
[10:37:35] <jp__> emailed few days ago
[10:38:20] <joe9> JT-Shop: thanks.
[10:42:51] <JT-Shop> let me go check my spam folder
[11:41:07] <skorket> I'm trying to figure out how to cut aluminum, and if it's even possible on my machine. Could someone give me a suggestion as to what bit to use and what feed rate to use if I have an 8000 RPM spindle?
[11:43:11] <JT-Shop> what kind of machine?
[11:43:52] <skorket> it's a 7"x7" kit from zen toolworks. It's made out of PVC
[11:44:39] <skunkworks__> heh'
[11:44:41] <skunkworks__> sorry
[11:44:48] <JT-Shop> what size end mill?
[11:44:59] <skunkworks__> high rpm - small mill - slow feed - lots of coolant.
[11:45:32] <JT-Shop> and how many flutes?
[11:45:37] <JT-Shop> hi Sam
[11:46:05] <skorket> The spindle takes a 1/8" shank, but other than that, I'm open to suggestions.
[11:46:28] <JT-Shop> are you wanting to engrave or mill out a pocket or what?
[11:46:39] <skorket> mill out a pocket
[11:46:55] <skunkworks__> Hi john
[11:47:14] <cradek> I'd have to go with not possible
[11:47:28] <skunkworks__> Chris!
[11:47:34] <cradek> uh-oh
[11:47:41] <skorket> cradek, I've heard that around, why do you say that?
[11:48:14] <cradek> it's made out of pvc
[11:49:02] <skorket> if you go slow, with a small mill, you still wouldn't be able to mill out something?
[11:49:15] <skorket> skunkworks__, do you have a suggestion as to the bit size and speed?
[11:49:45] <skunkworks__> not really - I have never tried on something that flimsy
[11:49:51] <JT-Shop> if you just want to find out for a 1/8" 2 flute carbide end mill at 8k rpm go 15IPM or so
[11:50:26] <skunkworks__> cradek: did jepler try to cut anything aluminum on his?
[11:50:33] <skunkworks__> On his zenbot
[11:50:45] <JT-Shop> skorket: http://www.lakeshorecarbide.com/18variable2fluteendmillforaluminumzrn.aspx
[11:50:52] <skunkworks__> That is a bit stiffer...
[11:51:00] <cradek> skunkworks__: no, that'd be crazy
[11:51:26] <cradek> fortunately carbide bits that small don't cost much. I recommend getting about 10 of them
[11:51:35] <JT-Shop> skorket: you can't go slow or the alum will generate enough heat to weld to the end mill
[11:51:41] <JT-Shop> LOL
[11:51:51] <skunkworks__> well - that is why I say lots of coolant...
[11:51:57] <skorket> JT-Shop, yeah, 15 ipm is really fast
[11:52:00] <cradek> 10 is probably enough to get you through to the end of the experiment :-)
[11:52:11] <JT-Shop> not for 8k rpm
[11:52:30] <skorket> JT-Shop, may I ask how you came up with those numbers?
[11:52:43] <JT-Shop> my feed and speed charts
[11:53:01] <JT-Shop> they are on the link as well
[11:53:43] <JT-Shop> I also have a spreadsheet to convert sfm diameter and # of flutes to rpm and ipm
[11:54:23] <skorket> and the general rule of thumb is to go as deep as half of the bit diameter? In this case, take of 1/16" of an inch at a time?
[11:54:33] <JT-Shop> actually that 1/8" bit should be going 53k rpm and 100 IPM
[11:54:46] <skunkworks__> wouldn't that be nice..
[11:54:55] <skunkworks__> JT-Shop: how is the converting going?
[11:55:13] <JT-Shop> hooking up the relays if I had some
[11:55:25] <JT-Shop> limits and inputs done
[11:55:34] * skunkworks__ likes opto22 stuff
[11:55:35] <JT-Shop> MPG next I think
[11:56:30] <JT-Shop> I have one SSR for the power supply to the drives and the rest are tiny relays for case fan, lube pump, drive enable
[11:58:29] <skorket> JT-Shop, so should I not even try the 1/8" bit at 8k rpm and 15 ipm?
[11:59:22] <JT-Shop> I cut with an 1/8" bit at what ever rpm the machine can muster and adjust the feed to get the proper chip load
[11:59:48] <r00t4rd3d> i used 1/8 bit at 12k rpm and 12ipm :D
[11:59:56] <r00t4rd3d> used/use
[12:00:06] <skorket> and 15 ipm is fast enough?
[12:00:09] <jdh> with a less rigid machine, you might not be able meet the chip load spec
[12:00:23] <JT-Shop> fast enough for what?
[12:01:00] <skorket> to mill out material or to not weld the bit to the material...
[12:01:23] <skorket> What if I use a maller bit, 1/16" say?
[12:01:35] <archivist> skorket, now I know the machine is flimsy, conventional milling ONLY
[12:01:53] <skorket> archivist, aluminum is non convential?
[12:02:03] <skorket> *conventional
[12:02:36] <archivist> climb milling gets a better finish, you machine cannot manage that
[12:03:05] <skorket> ok
[12:03:45] <archivist> you will be breaking bits till you learn how little you can cut per pass
[12:05:39] <archivist> the cutting force reaction goes through the frame which is plastic and flexible
[12:06:09] <jp__> any way to remove limits on a rotary axis?
[12:06:34] <IchGuckLive> 0-360 or the 9999
[12:06:46] <archivist> I set my limits insanely high 9999
[12:06:55] <JT-Shop> I seem to recall someone setting them absurdly high for some reason I now forget
[12:07:14] <jp__> still getting cant exceed pos limit when set to 9999
[12:07:36] <JT-Shop> -9999 and 9999?
[12:07:36] <skunkworks__> what is the gcode?
[12:07:42] <jp__> and it was just g01 a15
[12:07:49] <IchGuckLive> is there a higher in your G-code
[12:08:21] <IchGuckLive> G01 will not work G0 shure
[12:08:35] <archivist> jp__, did you home the axis
[12:08:48] <jp__> yes
[12:09:13] <jp__> sorry meant g0 a15
[12:10:19] <archivist> are you rotating in one direction for many revolutions
[12:10:35] <jp__> yes
[12:11:54] <archivist> a limit of 9999 degrees is only 27.775 revs
[12:12:24] <JT-Shop> set your limits to 99999
[12:12:33] <archivist> another reason one needs to be able to goto nearest 0 deg
[12:12:43] <JT-Shop> that is 277 revs
[12:13:08] <jp__> My bad f'ed up my ini with the 2nd yaxis motor
[12:13:39] <jp__> works now
[12:18:08] <skunkworks__> how is the extruder going?
[12:21:03] <jp__> Just trying to get the hot end right i ditched the peek for polyimide
[12:21:47] <jp__> running a prog right now without the hotend to test out the machine
[12:26:08] <jonathan_> anybody built a custom hm2 firmware lately?
[12:28:20] <gmagno> damn, I'm really having a hard time trying to find out what Roughing Offset means in image_to_gcode... I've tried with different simple linear gradient images, but still have no idea what that param means... could someone give me a hint?
[12:28:29] <jonathan_> I got to the point of building the custom bit files but the script says "xst: not found"
[12:32:14] <jonathan_> Tom_itx, are you around?
[12:44:44] <gmagno> hmm I assume that image_to_gcode is not very popular here... :-/
[12:45:23] <IchGuckLive> gmagno: Hi how is it going
[12:45:41] <IchGuckLive> shoudt i send another image
[12:46:03] <gmagno> Hey IchGuckLive :)
[12:46:30] <IchGuckLive> i modified som today
[12:46:39] <IchGuckLive> from the japan side
[12:47:00] <IchGuckLive> gmagno: do you got Blender working on your PC
[12:47:16] <IchGuckLive> i got also the §D of Lola
[12:47:19] <IchGuckLive> 3s
[12:47:21] <gmagno> I'm currently trying to machine a very simple image, a mountain :) I'm using image_to_gcode. But I'm not quite sure about what "Roughing Offset" means
[12:47:23] <IchGuckLive> as stl
[12:47:23] <gmagno> I do
[12:47:45] <gmagno> I'm not a guru, but I used blender a lot in the past
[12:47:49] <IchGuckLive> its just material alowence
[12:48:19] <IchGuckLive> il send you a mail
[12:50:36] <gmagno> tuning this parameters is crucial for a good tradeoff between having a good piece of work and time spended on making it
[12:50:45] <IchGuckLive> gmagno: so you know howto join meshes
[12:51:10] <IchGuckLive> gmagno: why not 0 ZERO
[12:51:34] <gmagno> IchGuckLive, I'm machinning MDF
[12:51:45] <gmagno> I think I would kill the drill bit
[12:51:55] <gmagno> need to do some passes
[12:52:04] <gmagno> this is a 2mm drill Im using
[12:52:37] <IchGuckLive> if you zig zag from outwards at 4mm depth it ahoudt work
[12:52:50] <archivist> !!!
[12:52:55] <IchGuckLive> Why dident you use NECURON or sutch stuff
[12:55:09] <gmagno> necuron is the material?=
[12:56:11] <archivist> I question the wisdom of 2mm bits and mdf,
[12:56:18] <gmagno> IchGuckLive:"if you zig zag from outwards at 4mm depth it ahoudt work". Im not sure I understand what you mean
[12:56:26] <IchGuckLive> its basicly a wooden like 2cplastic that you can chip with a 1mm bit
[12:56:57] <gmagno> archivist, what's wrong with that?
[12:57:06] <IchGuckLive> 4mm Depth 0.5 Stepover
[12:57:18] <IchGuckLive> gmang Your country is
[12:57:34] <gmagno> IchGuckLive, how is that relevant for our discussion?
[12:58:30] <archivist> gmagno, you will probably be getting the flutes bunged up
[13:00:17] <IchGuckLive> i need ro reload the PC one moment
[13:00:19] <archivist> experiment and see how well it works
[13:04:11] <IchGuckLive> gmagno: Mail is out
[13:04:35] <IchGuckLive> i need to go cause No Rain Garden is Dry as Desert
[13:26:20] <gmagno> once again I was being too conservative. I'm doing deeper roughing steps and everything's fine
[13:39:12] <archivist> cut too little, it is slow and the tool can wear out quickly, cut too much flutes clog cannot clear the chips tool snaps/burns
[13:59:42] <jp__> can the jog speed in axis be changed to read in units per sec?
[14:04:03] <JT-Shop> you could modify axis.py or add perhaps to .axisrc
[14:04:40] <JT-Shop> there is a circuit board behind my MPG on the Anilam... I assume I don't need that with my 7i77
[14:08:29] <skunkworks__> does it seem like a normal mpg?
[14:09:42] <JT-Shop> yea, has 5v, 0v, A, B terminals
[14:09:58] <JT-Shop> I think it is a comm board back to the PC
[14:10:07] <jp__> A gcode of F540 would equal 540 inches/min in imperial and 540mm/s in metric correct?
[14:10:33] <JT-Shop> 540mm/min
[14:11:14] <jp__> thx
[14:11:27] <JT-Shop> http://linuxcnc.org/docs/html/gcode/machining_center.html#sub:feed-rate
[14:20:51] <FinboySlick> Oops, my computer was plugged into that one ;)
[14:21:10] <jp__> Whats the best method to treat my 4th axis as a linear axis
[14:21:23] <FinboySlick> jp__: Know your diameter.
[14:21:28] <jp__> yes
[14:21:44] <FinboySlick> sorry, that's as far as my knowledge go
[14:23:07] <JT-Shop> your 4th axis is an extruder?
[14:23:15] <jp__> yeah
[14:24:02] <jp__> i have the step scale set. so if i do a g01 a1 i get one inch of material fed
[14:24:07] <JT-Shop> so all you want to do is turn the extruder motor so many steps
[14:24:20] <JT-Shop> there you go
[14:24:30] <jp__> no move it a certain distance
[14:24:47] <JT-Shop> ??
[14:25:05] <jp__> but how does the feedrate apply when i do that?
[14:25:26] <JT-Shop> is it configured as a linear or rotary?
[14:26:02] <jp__> i set it to linear but in axis i still see the jog slider in deg/min
[14:26:27] <jp__> should the slider not disappear if the axis is a linear one
[14:27:14] <JT-Shop> what coordinates are you using in the [TRAJ] section?
[14:27:51] <jp__> X Y Z A, i tried U but got nasty error messages
[14:28:01] <JT-Shop> about?
[14:28:08] <jp__> one sec
[14:29:05] <JT-Shop> for U you need joints = 7 and AXIS_6 for U
[14:29:44] <jp__> http://pastebin.com/6dLNH6hk
[14:29:57] <jp__> ah thats why then
[14:32:12] <jp__> Now i have a U axis
[14:33:47] <jp__> JT-Shop: Much better now Thanks
[14:33:54] <JT-Shop> welcom
[14:33:55] <JT-Shop> e
[14:34:44] <jp__> I wonder why i haven't heard of others having to do the same?
[14:57:02] <tjb1> r00t4rd3d: You here
[14:59:06] <tjb1> My z axis is 20lbs, is that too much?
[14:59:46] <JT-Shop> my z axis is 400lbs
[15:00:49] <tjb1> 1 nema 23 320 oz will be driving it
[15:01:52] <tjb1> That a good weight or too much?
[15:04:03] <archivist> some have a balance weight to reduce Z load
[15:04:10] <archivist> or spring
[15:06:42] <tjb1> Its not a load the motor will see, this is the entire z axis
[15:06:56] <tjb1> It bolts to 2 carriages on the gantry
[15:07:52] <archivist> the Z motor sees the spindle motor assembly weight
[15:08:44] <tjb1> No...my z motor is bolted to an extrusion...this whole assembly tgat bolts to the gantry weighs 20lbs
[15:09:06] <archivist> X or Y see the carriage (including Z) mass
[15:09:10] <tjb1> Im not concerned with the z motor liad
[15:09:13] <tjb1> Load
[15:09:45] <tjb1> Id like to know if this is too much for the y motor
[15:09:48] <JT-Shop> yea! MPG done
[15:09:56] <tjb1> 3:1 r&p drive on y
[15:10:00] <archivist> but..only 20lbs
[15:10:19] <tjb1> So its not too much?
[15:13:30] <JT-Shop> what is axis.n.wheel-jog-active?
[15:13:39] <JT-Shop> it's not in the manual :(
[15:14:29] <JT-Shop> oh, it's listed as a debugging pin with no description
[15:14:52] <jp__> i think for individual axis jog wheels or mpg's
[15:15:03] <jp__> it's a readback right
[15:15:35] <archivist> on off to light an led?
[15:16:47] <jp__> Thinks it's time to mount the extruder and lit it rip!!!
[15:17:23] <skunkworks__> Video!!
[15:17:43] <jp__> let me get thru my first real run!!!
[15:18:01] <jp__> still lots of time to crash stuff!! lol
[15:18:32] <jp__> The steppers sound cool kinda musical
[15:19:24] <JT-Shop> it is an out pin
[15:20:47] <jp__> yeah lets you know that that axis is in jog mode right?
[15:21:18] <jp__> i think i used it when i was working on my teensys pendant
[15:23:18] <JT-Shop> you mean jog-enable?
[15:24:11] <JT-Shop> nope not that
[15:25:29] <JT-Shop> maybe it is on when your jogging with the remote device
[15:28:19] <jp__> i can check on my mill if you want
[15:29:04] <JT-Shop> naw it's ok
[15:29:35] <jp__> just did that is it
[15:29:52] <jp__> when ever i trn my mpg it is on
[15:30:21] <jp__> i was using it anyways to drillmy extruder mount
[15:30:32] <JT-Shop> ok, cool
[15:31:07] <jp__> "Linuxcnc reprap" -linuxcnc machines making other linuxcnc machines LOL
[15:41:03] <JT-Shop> I used my plasma cutter to make parts for my plasma cutter while building it
[15:42:34] <FinboySlick> Hmmm, can I set acceleration on the spindle itself so that the machine would wait until my spindle has spun up to starts cutting. I add a dwell at the top of all my gcode in the meantime but it'd be cool to have EMC figure that one out.
[15:42:56] <JT-Shop> spindle-at-speed or something like that
[15:45:44] <JT-Shop> http://linuxcnc.org/docs/html/man/man9/axis.9.html
[15:45:55] <FinboySlick> Hmmm, that requires an encoder though, no?
[15:48:37] <JT-Shop> it is a bit
[15:49:21] <JT-Shop> do you control your spindle with linuxcnc
[15:49:33] <FinboySlick> Just 0-10v pwm.
[15:49:52] <FinboySlick> I don't think the VFD outputs an RPM feedback.
[15:50:08] <JT-Shop> does it have an at speed output?
[15:50:19] <FinboySlick> It is full of chinese symbols ;) I wouldn't know even if it did.
[15:51:01] <JT-Shop> like Werner Von Braun "and I'm learning how to count down in Chinese"
[15:51:04] <FinboySlick> The mill as it is now doesn't seem to provide an 'at speed' output, but maybe the VFD does.
[15:51:37] <JT-Shop> if you can bring the at speed into the motion.spindle-at-speed your good to go
[15:54:20] <FinboySlick> JT-Shop: Yeah, I'll definitely look for something of the sort.
[15:54:52] <FinboySlick> It has an LED display that outputs stuff so there's got to be some sort of feedback.
[16:00:17] <DJ9DJ> gn8
[16:18:57] <JT-Shop> pcw_home: the enable + and - on the 7i77 can I use them to ground my enable on the drives? my drives ground the enable pin to enable the drive
[16:42:50] <pcw_home> Yes they are floating switches so the can either pull-up or pull-down
[16:44:09] <pcw_home> (but note that enables 0 ..4 switch at once, only enable 5 its independent, its intended for the spindle)
[16:59:12] <JT-Shop> ok, so I wire the enable line to enable + then take enable - to ground?
[17:09:34] <pcw_home> Yeah if grounding it enables the drive
[17:16:54] <pcw_home> (also make sure its within the specs of the Enable output OPTO = 50 mA an d 100V max)
[17:17:45] <JT-Shop> ok, thanks
[17:33:36] <r00t4rd3d> anyone have plans for a cool puzzle box?
[17:38:28] <FinboySlick> http://sv.wikipedia.org/wiki/Fil:Hellraiser_Puzzle_Box.jpg ;)
[17:40:28] <FinboySlick> Don't make it work as well as in the movie though.
[17:41:53] <Aero-Tec> got a question
[17:42:05] <Aero-Tec> I have a file loaded and wanted to edit it
[17:42:12] <Aero-Tec> hit the edit
[17:42:23] <Aero-Tec> the file opened in the editor
[17:42:35] <Aero-Tec> problem is I can not edit it at all
[17:42:39] <Aero-Tec> nothing
[17:42:51] <Tom_itx> rights?
[17:43:02] <r00t4rd3d> or in use
[17:43:04] <FinboySlick> Meaning that the editor doesn't get launched? Or you can't save?
[17:43:18] <r00t4rd3d> read only flag
[17:43:34] <Aero-Tec> I can select where to do a edit but the editor will not allow any key stokes
[17:43:57] <r00t4rd3d> right click the file and see what the permissions are
[17:44:07] <r00t4rd3d> well right click, properties
[17:44:08] <FinboySlick> Aero-Tec: That does sound like a permission issue or it being already opened.
[17:44:19] <Aero-Tec> if it was a file usage or premissions problem it should not load or save
[17:44:43] <Aero-Tec> it was opened on a network computer
[17:45:19] <Aero-Tec> but closed the file on the network computer and it still would not let a edit happen
[17:46:11] <Aero-Tec> maybe I need to reload it in EMC for it to work
[17:46:33] <pcw_home> Most editors will open a read only files, but prevent any changes (and remind you of this by beeping if you type)
[17:46:54] <Aero-Tec> if it was a permisions problem, why would the editor not allow any input?
[17:47:33] <pcw_home> because the file is read only so any input would be lost
[17:47:40] <Aero-Tec> no speakers on computer, but should still have the mother board beeper
[17:48:24] <Aero-Tec> ok
[17:48:25] <FinboySlick> Aero-Tec: A lot of desktop environments redirect that signal to the soundcard.
[17:48:29] <Aero-Tec> thanks for the input
[17:48:29] <pcw_home> usually theres so notifier on the editor (read only file) or some such
[17:49:07] <pcw_home> theres a notifier
[17:49:52] <Aero-Tec> it does have a built in sound card
[17:52:30] <JT-Shop> Aero-Tec: this in Ubuntu?
[17:54:47] <pcw_home> If it has a sound card beeps will be re-directed there for sure
[18:11:09] <r00t4rd3d> touti fruiti
[19:21:12] <tjb1> hey r00t4rd3d
[19:21:24] <r00t4rd3d> hey
[19:23:43] <Gabe_W> Hey everyone
[19:27:38] <Gabe_W> So the hal_gui is being tested, i want to add either threading or multiprocessing to improve performance
[19:27:57] <Gabe_W> what route should i take?
[19:29:08] <r00t4rd3d> JT-Shop would be the guy to ask probably
[19:30:03] <jdh> you use a mac?
[19:30:26] <Gabe_W> no
[19:30:30] <Gabe_W> xubuntu
[19:30:34] <Gabe_W> 12.04
[19:30:39] <jdh> <oops>
[19:30:52] <Gabe_W> i eat mac and cheese though
[19:31:00] <Gabe_W> on occasion
[19:31:25] <Gabe_W> im just going to go with threading, its mainly for i/o functions any way
[19:32:32] <Gabe_W> I almost broke down and re-wrote it in C
[19:32:47] <Gabe_W> but i would like to go outside and see the sun sometime soon
[19:33:36] <Gabe_W> im loosing pigmentation in my skin, and my pupils won't adjust to light any more
[19:33:58] <Gabe_W> i also have a strange twitch in my right thumb
[19:34:17] <FinboySlick> Gabe_W: Replace the CCFLs in your monitor by UV ones.
[19:34:29] <Gabe_W> lol
[19:35:46] <Gabe_W> who knew programming was so fun?
[19:35:53] <Gabe_W> everyone kept telling me how boring it was
[19:36:24] <Gabe_W> ever since i learned it, i can't stop doing it. im addicted
[19:37:19] <FinboySlick> Gabe_W: Rewriting linuxcnc all in the same language should keep you busy for a little while.
[19:37:32] <Aero-Tec> JT-Shop: sorry for the delay in getting back to you
[19:37:40] <jdh> what language?
[19:37:47] <Aero-Tec> yes Ubuntu
[19:37:52] <Gabe_W> im not that interested in LinuxCNC
[19:38:07] <Gabe_W> i just use it for 'hal"
[19:38:09] <Gabe_W> :)
[19:38:50] <Gabe_W> i decided to learn C and Python
[19:38:57] <Aero-Tec> Gabe_W: what computer language are you using for writing programs?
[19:39:00] <Gabe_W> i had already had experience in C
[19:39:13] <FinboySlick> Gabe_W: They'd be my two choices too.
[19:39:18] <Aero-Tec> so your hooked on C?
[19:39:18] <r00t4rd3d> how you get it working with 12.04?
[19:39:30] <Gabe_W> magic :)
[19:39:51] <r00t4rd3d> i was just wondering your method as i know its possible
[19:39:59] <Aero-Tec> C or C++?
[19:40:23] <Gabe_W> actuall the code is( up, up, left, right, left, R1, R1,analog right)
[19:40:33] <Gabe_W> that will get it working on 12.04
[19:40:48] <r00t4rd3d> great, another smart ass to add to the group
[19:40:52] <Gabe_W> lol
[19:40:59] <Gabe_W> this WillenCMD
[19:41:05] <Gabe_W> this is my real name :)
[19:41:05] <r00t4rd3d> oh
[19:41:12] <FinboySlick> Gabe_W: Did you use an old kernel or did you manage to hack realtime into a modern kernel?
[19:41:12] <Gabe_W> so i have been here a while
[19:41:26] <r00t4rd3d> did you follow a guide for 12.04?
[19:41:31] <r00t4rd3d> ive seen one
[19:41:38] <r00t4rd3d> never tried it though
[19:41:40] <Gabe_W> yes, but its not perfect
[19:41:48] <Gabe_W> i had to make a few changes
[19:42:03] <Aero-Tec> you should write up the corrections
[19:42:19] <r00t4rd3d> and rework a livecd
[19:42:37] <r00t4rd3d> so all can easily do it
[19:42:45] <Aero-Tec> get the corrections into the docs for EMC
[19:43:13] <Gabe_W> im still working on grub, it won't show the kernel in the menu at startup
[19:43:25] <r00t4rd3d> what guide did you follow?
[19:43:26] <Gabe_W> you have to select previous kernel
[19:43:49] <Gabe_W> you also can't get the linuxcnc-dev from the deb repo either
[19:44:33] <r00t4rd3d> http://permalink.gmane.org/gmane.linux.distributions.emc.user/34836
[19:44:35] <Aero-Tec> Gabe_W: what is it your doing with EMC?
[19:44:49] <Gabe_W> alot, i control my sprinkler system with it
[19:44:57] <ReadError> hacking the gibson
[19:45:02] <Aero-Tec> or the HAL part of EMC?
[19:45:04] <Gabe_W> all the machines i design and build, i write gui's and use hal
[19:45:26] <Gabe_W> its the coolest piece of software i have used besides solidworks
[19:45:32] <Gabe_W> im addicted to solidworks also
[19:45:43] <Aero-Tec> your writing GUIs ?
[19:45:49] <Gabe_W> yep
[19:45:54] <Aero-Tec> what are you using to do that?
[19:45:56] <Aero-Tec> C?
[19:46:20] <Gabe_W> sometimes, but i write hal components to control any real time code
[19:46:31] <Gabe_W> python is the front end
[19:46:46] <Gabe_W> use the hal module
[19:46:52] <Gabe_W> to create pins
[19:46:53] <Aero-Tec> you should write up a how to manual so others can do the same thing
[19:47:00] <Gabe_W> im doing one better
[19:47:17] <Gabe_W> i writing configurator software all in one for linuxCNC
[19:47:23] <Gabe_W> i posted some screen shots
[19:47:28] <Aero-Tec> cool
[19:47:41] <Aero-Tec> when do you think you will have it done?
[19:47:43] <Gabe_W> it will have an auto-net for linking hal components, along with a hal comp ide for writing components
[19:47:48] <Aero-Tec> and how is it going?
[19:48:19] <r00t4rd3d> where did you post the screenshots?
[19:48:41] <Aero-Tec> will you be selling it or will it be open source?
[19:49:21] <Gabe_W> free its the least i can do
[19:49:42] <Gabe_W> for all the help i was given by people on here
[19:49:55] <Gabe_W> https://plus.google.com/photos/108420335892310746315/albums/5784211124086428513
[19:50:06] <Aero-Tec> r00t4rd3d: are you going to keep testing my password?
[19:50:23] <Gabe_W> that was it last week, it has changed since then
[19:50:31] <Aero-Tec> had a message you had given it another try awhile ago
[19:50:39] <Gabe_W> now it pulls all the manual's up for the components when you load them
[19:51:01] <Gabe_W> i'll post more tomorrow
[19:51:50] <Aero-Tec> looks cool
[19:51:58] <Gabe_W> i want to improve the setup for first time user's
[19:52:22] <Aero-Tec> amen to that one
[19:52:40] <r00t4rd3d> Aero-Tec, ? password?
[19:52:55] <Aero-Tec> being a new guy and having to go through it
[19:53:25] <Gabe_W> once you understand the way it works, its super easy
[19:53:36] <Aero-Tec> your innocent I bet
[19:53:38] <Aero-Tec> lol
[19:53:46] <r00t4rd3d> i have no clue what you are talking about
[19:53:53] <Aero-Tec> lol
[19:54:07] <r00t4rd3d> enlighten me
[19:54:24] <Aero-Tec> I had got a message you had given it another try
[19:54:38] <r00t4rd3d> wtf are you talking about
[19:54:56] <Aero-Tec> maybe it was a repeat of a old message
[19:55:15] <r00t4rd3d> again
[19:55:16] <r00t4rd3d> wtf are you talking about
[19:55:20] <Aero-Tec> you had tried my old password for my name

[20:18:09] <FinboySlick> Gabe_W: I don't think there are any strict rules on that.
[20:18:53] <wooo> hey guys i want to make some project of database management and i want to include some linux in in means to make some database of linux files or something else...please suggest me something..
[20:19:28] <FinboySlick> wooo: huh?
[20:19:32] <Aero-Tec> what is the DB for?
[20:19:38] <Aero-Tec> db
[20:19:55] <Aero-Tec> and also huh?
[20:20:13] <Gabe_W> make that three huh's?
[20:20:19] <Aero-Tec> you need to explain your project more
[20:21:02] <Gabe_W> Aero-tec is your name of any relevance?
[20:21:09] <Gabe_W> a company name?
[20:21:18] <r00t4rd3d> i mute nascar when they pray
[20:21:18] <Aero-Tec> yes
[20:21:24] <Aero-Tec> my company
[20:21:38] <FinboySlick> Aero-Tec: You make those bubbly chocolate bars?
[20:21:46] <wooo> actually i want to make a cool project pf database management as my college project...but i cant find some topic...i want to make some database of linux files or project related to linux..
[20:21:47] <Gabe_W> lol
[20:21:49] <Aero-Tec> lol
[20:22:15] <Gabe_W> there is an Aero-Tec shop here locally
[20:22:30] <Aero-Tec> where do you live?
[20:22:36] <wooo> please help
[20:22:57] <Aero-Tec> there are tons of EMC files you can play with
[20:23:13] <r00t4rd3d> Dennis?
[20:23:17] <wooo> Aero-Tec: are you asking me?
[20:23:21] <Gabe_W> Im not supposed to give my address to stranger's
[20:23:30] <Aero-Tec> lol
[20:23:32] <Gabe_W> so what's your real name?
[20:23:40] <Gabe_W> then we won't be stranger's
[20:23:40] <Aero-Tec> Stan

[20:24:20] <r00t4rd3d> who is fat and can be cartman?
[20:24:51] <Aero-Tec> not my company
[20:24:51] <ReadError> r00t4rd3d, is mr garrison
[20:24:58] <Aero-Tec> I am in Canada
[20:25:04] <ReadError> you are ike then
[20:25:04] <Gabe_W> so it is your shop then
[20:25:06] <r00t4rd3d> i wouldnt tell people that
[20:25:08] <FinboySlick> ReadError: Respect my authorithay.
[20:25:27] <Aero-Tec> that does your local Aero-Tec do?
[20:26:04] <r00t4rd3d> too many companies names aero-tec/tek
[20:26:04] <Aero-Tec> yes it is my little home shop here in Canada
[20:26:11] <r00t4rd3d> where in canada?
[20:26:16] <Aero-Tec> true
[20:26:19] <r00t4rd3d> ontario?
[20:26:23] <Aero-Tec> west caost
[20:26:26] <r00t4rd3d> oh
[20:26:30] <Aero-Tec> coast
[20:26:52] <Aero-Tec> I have had this name for just about 30 years
[20:27:28] <wooo> please help guys!!
[20:27:33] <Aero-Tec> maybe over 30
[20:27:46] <Aero-Tec> will have to check the exact date
[20:27:48] <FinboySlick> wooo: You're probably not in the best channel for this sort of help.
[20:28:02] <r00t4rd3d> i still have no clue what he is talking about
[20:28:21] <FinboySlick> r00t4rd3d: My guess is a database for database's sake because that's his homework.
[20:28:50] <Aero-Tec> woo is doing some sort of db project for school
[20:29:03] <Aero-Tec> so he is looking for something to db
[20:29:33] <wooo> Aero-Tec: but also want to include some sort of linux in it..
[20:29:35] <ReadError> why the hell did he join here?
[20:29:36] <ReadError> ;p;
[20:29:39] <ReadError> lol
[20:29:54] <Aero-Tec> maybe he can be of help and db something for EMC
[20:30:31] <ReadError> but emc needs no db
[20:30:45] <r00t4rd3d> sure it does
[20:30:49] <r00t4rd3d> tools
[20:31:06] <ReadError> but thats loaded in a file is it not?
[20:31:08] <Aero-Tec> there is always a use for a db
[20:31:13] <FinboySlick> r00t4rd3d: But there's no linux in those tools.
[20:31:20] <Gabe_W> lol
[20:31:30] <jdh> lot of overhead for a tool table.
[20:31:38] <Gabe_W> FinBoySlick: out of nowhere with the jokes man
[20:31:41] <Gabe_W> love it
[20:31:44] <Aero-Tec> he can include linux stuff as well
[20:31:50] <Gabe_W> like .txt files
[20:32:09] <Gabe_W> oh oh and maybe search the directory
[20:33:17] <Aero-Tec> wooo: there are tons of files on the server you can download
[20:33:46] <Gabe_W> i don't think you can weigh a file, so a ton is an inaccurate measurement
[20:33:52] <Aero-Tec> some linux stuff as well
[20:33:54] <Gabe_W> i would say there are several
[20:34:13] <wooo> Aero-Tec: what are these EMC files you are talking about?
[20:34:28] <Gabe_W> like the X files only better
[20:34:35] <Aero-Tec> lol
[20:34:51] <FinboySlick> But the filesystem *is* the database.
[20:35:02] <Aero-Tec> the server has a ftp option does it not?
[20:35:22] <Aero-Tec> where he can lookk at the files
[20:36:13] <Aero-Tec> it is a list of files in a file system order, but it is not a db
[20:36:49] <Gabe_W> woo: i only kid
[20:37:15] <Gabe_W> i once seek project to make linux to database format also
[20:38:36] <Gabe_W> i can't get motivated
[20:41:00] <Gabe_W> im trying to change the touchpad driver to decrease the touchpad area on my laptop
[20:41:29] <Gabe_W> this laptop has a touchpad the size of an ipad, and its a pain to type on
[20:41:50] <Gabe_W> either that or i have really wide palms
[20:42:02] <FinboySlick> Gabe_W: I hate trackpads. I always go for lenovo trackpoint (or whatever pro laptop has them).
[20:42:17] <FinboySlick> And I disable the trackpad.
[20:42:28] <FinboySlick> Or just use it as a large scroll wheel.
[20:42:46] <Gabe_W> i remember those eraser looking things in the center of the keyboard
[20:42:53] <Gabe_W> they still have those?
[20:42:54] <FinboySlick> Yup. They rock.
[20:42:54] <Gabe_W> :)
[20:43:19] <FinboySlick> It's right on home row.
[20:43:52] <FinboySlick> And it won't drag when you're trying to click or other trackpad-y nonsense.
[20:44:19] <Gabe_W> i love when i type, and it randomly jumps like 400 lines up
[20:44:26] <Gabe_W> thats my favorite
[20:44:45] <FinboySlick> So yeah. Next laptop, go for something that has one of those, you won't regret it.
[20:44:50] <Gabe_W> its a game, i play when i want to edit line 37 i got to 400 and try to magically get up there
[20:45:35] <Gabe_W> i can disable it while typing but then i have to wait for it to release and i don't have the patients
[20:46:20] <FinboySlick> Gabe_W: To me, that's just a bandaid solution on a poor design.
[20:46:38] <Gabe_W> i can say that about half the things i own
[20:47:11] <Gabe_W> except for linux, i really am pleased with how stable it is, linuxcnc, is bullet proof
[20:47:22] <Gabe_W> i first started using cough cough "mach3" cough
[20:47:36] <Gabe_W> even payed for it.... i know shame on me
[20:47:44] <Gabe_W> but i was ignorant
[20:48:10] <Gabe_W> actually the customer paid for it
[20:48:27] <Gabe_W> i have only paid for one piece of software, that was pro-tools 9
[20:48:42] <FinboySlick> Gabe_W: And Solidworks, right?
[20:48:44] <Gabe_W> the rest i have found on the ground or one in give aways
[20:48:49] <Gabe_W> won*
[20:49:20] <Gabe_W> no i found solidworks on a cd someone dropped at the machine show
[20:49:32] <Gabe_W> crazy i know... but finder's keepers
[20:51:37] <Gabe_W> there are 3 of the .conf for synaptics
[20:52:03] <Gabe_W> any idea how to determine the appropriate one, i wonder if its in the .profile in the home directory
[20:52:48] <Gabe_W> im becoming pretty familiar with linux... a slow and steady process i actually prefer command line. its like going back in time but its faster i swear
[20:53:26] <Gabe_W> i can copy or make a link to a file faster than if i used nautilus anyone else agree?
[20:54:05] <Gabe_W> im talking to my self again... damn sometimes late at night i use this irc as a diary when no on is on
[20:54:19] <Gabe_W> dear diary: today was a good day
[20:55:29] <Gabe_W> or captains log: stardate 9/8/2012 i encountered an unusual phenomenon
[20:55:31] <jdh> except
[20:58:21] <Gabe_W> maybe its a sign
[20:58:40] <Gabe_W> like 'if we act like we can't hear him maybe he will leave"
[21:16:30] <r00t4rd3d> we tried that with you already, doesnt work.
[21:34:18] <FinboySlick> Anyone has a simple drilling/breakoff .py routine all coded up?
[21:35:32] <FinboySlick> Nevermind.
[21:35:46] <FinboySlick> Hehe, should have just looked at the site ;)
[21:45:21] <Gabe_W> it worked for a while but im back
[21:51:13] <Gabe_W> i think the saying "why re-invent the wheel" is a horrible phrase
[21:52:46] <Gabe_W> I'ts just like when my boss tells me "thats the way we have been doing it for years, why should fix it if it
[21:52:52] <Gabe_W> s not broken
[21:52:53] <Jymmm> No, but "We need to talk" is.
[21:53:27] <Gabe_W> my comment back is are you still watching a black and white tv? they said no, well did your's break or did you just want a color.
[21:53:55] <Gabe_W> if we lived by those philosophies we would still be primitive cave dwelling creatures
[21:54:10] <Gabe_W> we build a house when this cave is already here
[21:54:40] <Jymmm> but thats inventing a house, not another cave.
[21:55:19] <Gabe_W> no the cave is a house, a dwelling place where one lives, a house doesn't have a material requirement
[21:55:24] <Jymmm> The "if it aint broke" is mostly the definition of "broke"
[21:55:39] <toastydeath> "why re-invent the wheel" is usually an admonishment against "not invented here" syndrome
[21:55:53] <Jymmm> a cave is a dweeling for millions of bats for millions of years
[21:56:13] <Gabe_W> so i should move out of my cave then?
[21:56:18] <Gabe_W> because bats where here first?
[21:56:39] <Jymmm> Which point are you arguing? wheel or broke?
[21:57:39] <Gabe_W> both
[21:57:51] <Jymmm> you cant, they are diffeent things.
[21:58:50] <Gabe_W> true but both are incorrect
[21:59:13] <Gabe_W> just saying in general... most don't make any sense
[21:59:37] <toastydeath> rather than seeking to understand advice, it looks like you're merely arguing against it without first considering it
[21:59:47] <Jymmm> theres no need for a school kid to go out and make their own pencils, when you can buy 24 for $1 (wheel). But if the kids wants a mechanical pencil so no have to ha a sharpener, sure (broke)
[22:01:56] <Gabe_W> so since you can buy 24 pencils for $1 you should just accept that?
[22:02:16] <Jymmm> shouldn't reinvent the wheel
[22:02:49] <Gabe_W> i disagree say you develop a material that is just like the led or graphite but never breaks or needs sharpening
[22:03:03] <Gabe_W> now you only need one
[22:03:06] <Jymmm> that's not wheel, that's broke
[22:03:20] <Jymmm> "if it aint broke, but it is!"
[22:03:37] <Jymmm> Like I said, they are two different things.
[22:03:56] <toastydeath> password storage.
[22:04:10] <Jymmm> One is replication the other is innovation.
[22:04:13] <toastydeath> nearly every website develops their own crypto and password storage/transmission
[22:04:18] <toastydeath> despite having NO domain knowledge.
[22:04:34] <Jymmm> toastydeath: Nah, that's just ego
[22:04:36] <toastydeath> now, the developers could decide that they NEED to be domain experts
[22:04:50] <toastydeath> in which case they can innovate.
[22:05:04] <toastydeath> in most cases, they wind up with a shittier solution than exists elsewhere and is prone to more failures.
[22:05:07] <Jymmm> they're too stupid to innovate on that
[22:05:39] <Jymmm> "You know you're a dumbass... when you say that MD5 is encryption"
[22:05:49] <Gabe_W> so since Edison developed the light bulb and the use of DC current, then Tesla should of just said oh well with Alternating Current?
[22:06:20] <toastydeath> Gabe_W, that's not the issue at hand
[22:06:30] <Gabe_W> im confused now lol
[22:06:30] <toastydeath> Tesla wasn't wheelwright for wagons.
[22:06:43] <Jymmm> Edison stole the lightbulb, like he stole many things.
[22:06:48] <toastydeath> If tesla decided he wanted to make wheels, he had NO reason to think he could do it as well or better.
[22:06:53] <toastydeath> his wheels are going to be shit.
[22:06:55] <Jymmm> stole/boughtout, whatever =)
[22:07:19] <jdh> I don't think that's what it means.
[22:07:22] <toastydeath> and if he wants to make a wagon wheel of merely equal quality
[22:07:30] <toastydeath> he has to invest a shitload of time learning how to do it properly
[22:07:45] <jdh> it's wheel as a concept, not wheel as a manufactured item.
[22:07:46] <toastydeath> when he can just go out and for far less cost, buy a damn wheel.
[22:07:59] <toastydeath> jdh, I'm using the literal example because it illustrates the concept
[22:08:19] <jdh> no it doesn't.
[22:08:27] <toastydeath> okay, what does it mean?
[22:08:32] <jdh> it illustrates something completely different.
[22:08:45] <toastydeath> actually, I don't want to discuss this anymore
[22:08:48] <Gabe_W> wow, look i was just complaining
[22:08:52] <jdh> it means a wheel is just round
[22:08:52] <Gabe_W> lets move on lol
[22:08:59] <toastydeath> this is a stupid discussion and I'm annoyed i got into it
[22:09:28] <Jymmm> toastydeath: blame gabe and thru your poo at him for strting it!
[22:09:32] <Jymmm> throw
[22:09:35] <jdh> that's the point of the interwebbes
[22:09:53] <Gabe_W> i'll take the blame thats fine, just not the poo
[22:11:40] <Gabe_W> note to self, don't discuss 'figure's of speech' on irc
[22:12:41] <jdh> what is a "figure of speech" anyway?
[22:12:50] <jdh> is it a drawing, or a mannequin?
[22:13:00] <Jymmm> jdh: yo momma!
[22:13:09] <jdh> a bust of benjamin franklin orating?
[22:13:55] <Gabe_W> speaking of mannequin check this out http://youtu.be/DQpq1_pfIgk
[22:14:00] <Gabe_W> hilarious
[22:14:25] <Gabe_W> it was at a lake near buy
[22:14:29] <Gabe_W> by*
[22:47:44] <FinboySlick> Gabe_W: The driver swinging to the left is pretty priceless.
[22:52:52] <r00t4rd3d> Just finished reading No Easy Day, pretty good book.
[22:55:19] <taiden> whats up gents
[23:12:37] <Gabe_W> i know
[23:13:10] <Gabe_W> i watched it like 10 times,
[23:14:45] <r00t4rd3d> anyone do dovetail or finger joints on their router?
[23:16:45] <r00t4rd3d> im trying to figure out how to do it
[23:21:47] <Gabe_W> they sell a dovetail cutter
[23:21:57] <Gabe_W> do you have one?
[23:22:04] <r00t4rd3d> nope
[23:22:24] <r00t4rd3d> i want to make project boxes and stuff
[23:22:44] <FinboySlick> I could use someone with a bit of drilling experience myself (just to further my understanding).
[23:22:45] <Gabe_W> with sliding tops?
[23:23:27] <FinboySlick> Twist drills never go in where they're supposed to, apparently, so one needs to spot-drill, correct?
[23:23:42] <Gabe_W> what are you drilling?
[23:24:16] <FinboySlick> Relatively soft plastic, I think it's probably ABS.
[23:24:32] <Gabe_W> screw length drills or standard length
[23:24:37] <FinboySlick> I'm about 0.003" off on a 5/64 drill.
[23:24:47] <FinboySlick> Bog standard.
[23:24:52] <Gabe_W> thats not uncommon for plastic
[23:25:03] <Gabe_W> the head causes expansion
[23:25:05] <Gabe_W> heat*
[23:25:44] <FinboySlick> I'm off in terms of position, not diameter.
[23:26:02] <FinboySlick> (might be off there too, but it's not that big a deal)
[23:26:12] <Gabe_W> is it supported or does it flex?
[23:26:34] <Gabe_W> thats a small drill to not spot drill
[23:26:50] <Gabe_W> especially if its sticking out of the chuck more than an inch
[23:27:10] <FinboySlick> Gabe_W: Yeah. I was mostly just interested in what's going on there though.
[23:27:24] <FinboySlick> (this was a test hole)
[23:27:35] <Gabe_W> i could easily see this drill walking off
[23:28:27] <FinboySlick> The flex doesn't just mean my hole is in the wrong spot, right, it also means the hole isn't straight, doesn't it?
[23:28:55] <Gabe_W> it could be if the drill walks off i would bet its out of round and not straight
[23:29:49] <FinboySlick> Would spot drilling be enough to aleviate all of that?
[23:30:09] <Gabe_W> if you could pick up a #1 center drill
[23:30:26] <Gabe_W> drill about .083 deep
[23:31:28] <Gabe_W> the tip on a #1 is .051 if my memory serves me correctly
[23:31:47] <FinboySlick> I don't have a spot drill that small.
[23:31:58] <Gabe_W> #2?
[23:32:06] <Gabe_W> you can't go higher than a #2
[23:32:12] <Gabe_W> #3 pilot is .125
[23:32:31] <FinboySlick> That's the smallest I got if that.
[23:32:55] <Gabe_W> you could just try making a small plunge in with a number three
[23:33:12] <FinboySlick> OK, the cone is enough, I don't need a wall?
[23:33:40] <Gabe_W> talking about .03 max just don't put the pilot in
[23:34:10] <Gabe_W> i can't guarantee that the drill won't come out of that though
[23:34:16] <Gabe_W> what's your feed rate?
[23:34:36] <Gabe_W> i presume this is on a CNC
[23:34:44] <FinboySlick> I calculated 16ipm at 6000rpm.
[23:34:47] <FinboySlick> Yes.
[23:34:55] <Gabe_W> way to fast
[23:35:06] <Gabe_W> of a feed rate
[23:35:34] <FinboySlick> Went through 3/4 of plastic like butter though.
[23:36:13] <Gabe_W> i feed a .125 through delrin at about 50ipm but its a screw length drill
[23:37:23] <FinboySlick> The rule of thumb formula says 5/64 * 10 ipm.
[23:37:37] <FinboySlick> at 3000 rpm.
[23:37:58] <FinboySlick> I can't spin at 3k, so I went 6k and doubled the feedrate.
[23:38:11] <Gabe_W> speeding the rpm's up is not a problem
[23:39:01] <FinboySlick> I don't want it to melt its way through though, it has to do some cutting.
[23:39:02] <Gabe_W> its the feed rate you want to drill it plastic well flex you want to let the drill cut not push
[23:39:35] <Gabe_W> i would say 10ipm sounds okay, keep the rpms where they are
[23:39:46] <FinboySlick> 10ipm at 6k?
[23:41:18] <Gabe_W> yea give that a try hell you would be save at 6 or 8 ipm also is this a production part?
[23:41:34] <FinboySlick> Nah, one of two.
[23:41:42] <FinboySlick> But I have some scraps I can test in.
[23:43:23] <FinboySlick> With my previous params, the hole is loose at the entry and snug at the end.
[23:43:31] <FinboySlick> That's what made me wonder what's going on.
[23:44:01] <Gabe_W> typically that means it got hot
[23:44:09] <Gabe_W> how sharp is your drill?
[23:44:24] <FinboySlick> Brand new, but it's hardware store grade.
[23:44:30] <Gabe_W> should be fine
[23:45:04] <Gabe_W> as long as it wasn't used on steel previously
[23:45:39] <Gabe_W> try slow that feed down, chuck that drill up as high as possible
[23:45:54] <Gabe_W> rigidity rigidity rigidity
[23:45:57] <Gabe_W> :)
[23:46:18] <FinboySlick> It's in a R11 collet.
[23:46:34] <Gabe_W> thats good
[23:46:37] <FinboySlick> I still need to have it stick out 3/4" though since this is a through hole.
[23:46:55] <Gabe_W> try not to chuck up on the flutes
[23:47:16] <Gabe_W> so as short as possible without chucking up on the flutes
[23:47:26] <FinboySlick> Makes sense.
[23:47:44] <FinboySlick> They're Ti coated, but in that grade, I don't think it's meaningful. Might make them a bit more slippery.
[23:48:26] <Gabe_W> titanium nitrated absolutely worthless unless working in high temperature's
[23:49:10] <FinboySlick> Makes one wonder why they bother in bits that'll be chucked in battery powered hand-tools.
[23:49:33] <Gabe_W> because they will get excessively hot in a hand drill
[23:50:55] <FinboySlick> Anyway. Seems I've got everything ready for tomorrow.
[23:51:10] <FinboySlick> I'll look into getting video up of the part being born.
[23:51:39] <FinboySlick> milling tests were very promising.
[23:51:56] <FinboySlick> I'm getting awesome finish at the speed/feed I planned.
[23:52:57] <Gabe_W> thats good
[23:54:21] <FinboySlick> This soft plastic is really fun to work with.
[23:55:23] <Gabe_W> yeah cheap too
[23:56:04] <Gabe_W> i can fly through that stuff
[23:56:38] <FinboySlick> busybee has a 'Pla-Sticks' special. 10 bucks you get x pounds of random plastic stuff.
[23:57:45] <FinboySlick> Any time I order there, I get a pack or two.
[23:58:09] <FinboySlick> It's mostly flat stock and random extrusions.
