Back
[00:00:38] <XXCoder> cool I guess
[00:00:43] <XXCoder> ironically I love leather coat
[01:31:30] <Bushman> ave
[01:32:29] <Bushman> i have a g-code for a part but i'd like to make it multiple times one next to the other...
[01:33:43] <Bushman> any tips on which gcodes to use to make the machine mill one part after the other without me manually offseting it each time?
[01:34:21] <Bushman> it's nice and dandy when i'm doing 2 or 3... but i'll like to make a set of 10 for example
[01:34:58] <Bushman> *i'd like to
[01:42:08] <toastyde1th> Bushman, what control are you using
[01:45:38] <Jymmm> toastyde1th: CONTROL PANEL http://www.ironcowprod.com/wp-content/uploads/2011/12/frankensteins_laboratory.jpg
[01:46:00] <toastyde1th> AH AH AH
[01:48:54] <Bushman> toastyde1th: linuxcnc
[01:49:29] <toastyde1th> i don't have a solution for you for linuxcnc but i know for a fact there are really simple ways to do it on linuxcnc
[01:49:41] <Bushman> Jymmm: hehe :D
[01:49:42] <toastyde1th> stick around and ask periodically and you'll get a good solution
[01:50:17] <Jymmm> gcode nesting, interesting
[01:50:58] <Jymmm> Bushman: gimme an example of a part, and what the raw material is?
[01:51:56] <Jymmm> and rough dimensions of the material
[01:52:19] <Bushman> example part: polygon with few polyline openings in it. nothing fancy
[01:52:32] <Bushman> let's say a square with 3 holes in it
[01:52:33] <Jymmm> flat, like washer
[01:52:37] <Jymmm> ?
[01:52:39] <Bushman> yes
[01:52:48] <Bushman> material acrylic sheet 3mm thick
[01:52:51] <Jymmm> or gasket?
[01:53:08] <Jymmm> 3mm is what in inches?
[01:53:11] <Bushman> yea, like a gasket
[01:53:15] <Jymmm> 1/8"?
[01:53:21] <Bushman> close
[01:53:24] <Jymmm> k
[01:53:35] <Bushman> ~3.17 is 1/8"
[01:53:42] <Jymmm> close enough
[01:53:51] <Jymmm> prt dims?
[01:54:04] <Jymmm> part dimensions (max)?
[01:54:08] <Bushman> 20x30mm aproximitly
[01:54:12] <Jymmm> k
[01:54:21] <Jymmm> material dims (max) ?
[01:54:50] <Bushman> the problem is the code is in absolute coordinates system... if it was in relative i'd just nest it with a simple sub
[01:55:11] <Bushman> and even write the multiplying routine by hand...
[01:55:52] <Bushman> but since it isn't i'm wondering if there's something like g54 that i could use dynamically from within the program but still start wher my g54 is set by me
[01:55:55] <Jymmm> Then why don't you rewrite it in relative terms?
[01:56:15] <Jymmm> ah, you are trying to workaround the clusterfuck basically?
[01:56:24] <Bushman> yes
[01:56:25] <toastyde1th> Bushman, how i'd do it
[01:56:46] <Jymmm> Bushman: What if, you just lie to lcnc?
[01:56:51] <toastyde1th> is the controls I'm used to allow me to temporarily offset the work coords
[01:57:00] <Bushman> the thing is ther's a lot of curves on the parts... and i'll be getting more of those, not just this one code
[01:57:23] <Bushman> Jymmm: i'd love to do that... but what do you mean exactly?
[01:57:26] <Bushman> :P
[01:57:33] <Jymmm> Bushman: Just ie to her, tell her she's pretty =)
[01:57:50] <Bushman> oh, i'm telling it to her everyday ;]
[01:57:55] <Bushman> and i don't have to lie!
[01:57:57] <Jymmm> Bushman: bastard! lol
[01:58:02] <Jymmm> Awwwwwwwwwwww
[01:58:18] <Bushman> http://i.imgur.com/pEEYxmq.jpg
[01:58:26] <Bushman> isn't she gorgeous?!
[01:58:29] <Bushman> :D
[01:58:31] <toastyde1th> jymm - i recall linuxcnc using either g92 or g10 or some such?
[01:58:34] <toastyde1th> to set coords?
[01:58:49] <Jymmm> Bushman: If the raw material is 100x100, tell it it's 300x300 or whatever
[01:59:26] <Bushman> um... i don't think i follow?
[02:00:01] <Bushman> the materiall is arbitrary... (depends on how much acrylic i hack off)
[02:00:02] <Jymmm> Bushman: you are offsetting the material to compensate for the absilutele coordin
[02:00:13] <Bushman> yes
[02:00:30] <Bushman> to put the workpiece at 0,0,0
[02:00:46] <Bushman> cause that's what the gcode thinks it is
[02:01:05] <Jymmm> right
[02:01:14] <Bushman> but i want to do that once for all 10 itterations
[02:01:27] <Jymmm> but if the material is (virtually) 300x300 instead of 100x100, what happens?
[02:01:54] <Bushman> and then just, i don't know... set a grid value like: "put another part 35mm to the right and repeat"
[02:02:17] <Bushman> i'm not sure what you mean, i don't set any material
[02:02:36] <Jymmm> where is 0,0,0 on your machine?
[02:02:46] <Jymmm> absolute
[02:03:31] <Jymmm> in the pic you linked to, where is 0,0,0 ?
[02:03:32] <Bushman> it's my arbitrary decision to put it on left front bottom corner but it used to be in different places
[02:03:47] <Jymmm> bus well, make up your mind damnit =)
[02:04:06] * Jymmm slaps the arbitraryness out of Bushman!
[02:04:12] <Bushman> i don't have home switches... it's where i put it that day
[02:04:15] <Bushman> :D
[02:04:21] <Jymmm> then I cant help you
[02:04:28] <Bushman> why?
[02:04:54] <Jymmm> if you have code that is absolute, you need machine coordinates that are absolute too
[02:05:07] <Jymmm> not arbitrary for the day
[02:05:19] <Bushman> let's assume i will install the home switches and home the machine at left bottom front corner
[02:05:36] <Bushman> it's alway + vales
[02:05:41] <Jymmm> bottom left of photo?
[02:05:42] <Bushman> values
[02:05:46] <Bushman> yes
[02:06:25] <Jymmm> ok, so slap a 100x100 piece of acrtyic on there and mark 0,0,0 with a red dot
[02:06:31] <Jymmm> got it?
[02:06:42] <Bushman> ok
[02:06:47] <Jymmm> now...
[02:06:58] <Jymmm> tel the machine it's 400x400
[02:07:05] <Bushman> ok
[02:07:06] <Jymmm> NOW where is the red dot?
[02:08:02] <Jymmm> (Hint: its at an offset of a factor of 4)
[02:08:23] <Bushman> by "tell the machine" you mean g54?
[02:08:55] <Jymmm> You said your gcode is in absolute coor, right?
[02:09:23] <Bushman> yes, g90
[02:09:52] <Jymmm> I'm saying tell the machine that the absolute (vurutal) 0,0,0 is now at -4,-4,-4
[02:10:04] <Jymmm> (or whatever)
[02:10:36] <Bushman> still not following what for but please go on?
[02:10:43] <Jymmm> That's it.
[02:10:56] <Jymmm> you are just moving 0,0,0
[02:11:18] <Jymmm> to a spot that the machine physically does not exist
[02:11:25] <Bushman> ok, i'm moving it... with what exactly?
[02:11:27] <Jymmm> some where on the carpet
[02:11:42] <Jymmm> with where HOME is
[02:11:55] <Bushman> is there a specific g-code for that?
[02:12:01] <Jymmm> you are redefining HOME position
[02:12:05] <Jymmm> nfc
[02:12:34] <Bushman> cause that's what i'm looking for... a way to do it from withing a g-code routine
[02:13:27] <Jymmm> Interesting G28 http://www.cnccookbook.com/CCCNCGCodeG28ReturntoReference.htm
[02:14:37] <Jymmm> http://www.linuxcnc.org/docs/2.4/html/gcode_main.html#sub:G28,-G30:-Return
[02:15:20] <Jymmm> http://www.linuxcnc.org/docs/2.4/html/gcode_main.html
[02:16:13] <Jymmm> g10? http://www.linuxcnc.org/docs/2.4/html/gcode_main.html#sub:G10:-Set-Coordinate
[02:16:15] * Bushman is reading
[02:17:22] <Bushman> hmm... g10 won't work.. it just uses g54-59
[02:17:29] <Jymmm> http://www.linuxcnc.org/docs/2.4/html/gcode_main.html#r3_4
[02:17:34] <Bushman> i'd need to predefine the g54-59
[02:17:41] <Bushman> let me read the rest
[02:17:47] <Bushman> brb
[02:19:05] <Jymmm> REPEAT, g90,G91
[02:20:33] <Bushman> it uses g91. my code is in g90. that's the problem
[02:21:05] <Bushman> if it was output by the preprocesor in g91 i would have NO problem making it multiple times
[02:21:40] <Bushman> i would just write a simple loop that executes the code, then moves away predefined value and repeats the whole proces given number of times
[02:22:19] <Bushman> i'm looking for a way to go around it when i have a piece of code that i can't manually re-write in g91
[02:25:07] <Bushman> and this particular preprocesor does not give the option to output in g91 if you wonder
[02:31:37] <Bushman> ok, i think i might be getting somewhere...
[02:32:06] <Bushman> g10 l2 and g10 l20 seem to allow me to edit the offsets from withing the code...
[02:32:25] <Bushman> now i just need to properly understand it's workings and try to implement it
[02:48:11] <Bushman> that was so simple... g92
[02:50:19] <Bushman> g92 was a g-code i was looking for. i can go to the point where i want my next part origin to be and simply set it to 0,0,0
[02:50:42] <Bushman> simple as that. no G5x
[02:51:28] <mrsun> i was warned from using G92
[02:51:46] <mrsun> was better to use G10 L20 etc
[02:51:49] <mrsun> aparently
[02:52:05] <mrsun> oh you are on other coordsystems? :P
[03:17:30] <Bushman> mrsun: why did they warned you?
[03:20:46] <Deejay> moin
[03:21:14] <Bushman> ave
[03:28:34] <archivist> syyl_, if your lorch come with the headstock spanner I would love some measurements, and does the nut have a shakeproof washer, mine has, not sure if original
[03:35:31] <Bushman> on unrelated note: does anyone know any software for linux that is similar in functionality and usability to SheetCAM?
[03:35:47] <Bushman> ...but free.
[03:50:11] <archivist> Bushman, http://www.sheetcam.com/downloads
[04:08:31] <Bushman> archivist: 10:15:28 < Bushman> ...but free.
[04:13:36] <Bushman> my question seems to be vague to some people so i'll try to rephrase it...
[04:14:48] <Bushman> does anyone know any OTHER software than SheetCAM for linux that is similar in functionality and usability to SheetCAM, but free?
[04:44:20] <archivist> Bushman, did you try downloading and running the linux version :)
[06:30:23] <mrsun> Bushman: dont know realy ... but was better to use G10 for some reason =)
[07:03:52] <jthornton> hmmm a G2/3 arc will always have two sides that are equal length
[07:07:12] <Tom_itx> 8°F
[07:07:27] <jthornton> heat wave here 18F
[07:07:54] <Tom_itx> woo hoo!
[07:09:14] <skunkworks_> -8f here
[07:10:25] <jthornton> I'll be starting 2 fires up this morning for sure
[07:50:45] <XXCoder> 30s-40s f here
[07:51:08] <XXCoder> but constant rain I call washington foreverrain
[07:51:17] <XXCoder> its been raining for last 10 hours
[08:16:32] <archivist> syyl, I have made one http://www.collection.archivist.info/searchv13.php?searchstr=lorch+spanner
[08:18:34] <syyl_ws> sir, thats a nice spanner!
[08:18:58] <syyl_ws> i will look if my machine comes with one
[08:19:17] <archivist> still a bit thick though
[08:20:08] <archivist> the internet pictures I stole gave no dimensions so filed to fit
[08:30:22] <jdh> did you turn that free-hand?
[08:32:35] <archivist> yes
[08:32:48] <jdh> nifty
[08:32:56] <archivist> holding up the paper now and again
[08:33:11] <jdh> what kind of tool?
[08:33:41] <archivist> a graver
[08:36:25] <archivist> the internet does not have many videos of the process, it is a bit like wood turning
[08:37:25] <SpeedEvil> I imagine scrapers would work OK for metal
[08:37:31] <SpeedEvil> (the wood-turning sort
[08:37:47] <archivist> nah, wrong shape
[08:39:07] <archivist> http://www.suttontools.co.uk/hand-tools/lozenge-gravers.html but that does not show the tip grind
[08:40:45] <archivist> unfortunately hand engraving tools are also called gravers but the grind is a bit different
[08:41:53] <archivist> a favourite shape for me is the oval http://contenti.com/oval-gravers
[08:42:43] <jdh> does it want to dig in and fling the tool into your face?
[08:43:59] <archivist> you have the rest reasonably close to the work and have the tool pointing up at about 30 deg or whatever till it sounds and turns right
[08:45:34] <archivist> so it pushes the tool off rather than dig in, you have to apply some pressure
[08:50:35] <CaptHindsight> https://www.youtube.com/watch?v=PlZDg0rpIi8 my first thought was to grind it
[08:54:12] <CaptHindsight> Milling a camshaft (with EMC2) https://www.youtube.com/watch?v=YnABuOOoi5w
[08:59:47] <Loetmichel> mueller nick is a fine pal
[08:59:49] <Loetmichel> met him once
[09:00:00] <Loetmichel> sometimes a bit grumpy but fine
[09:00:48] <syyl_ws> just grumpy if someone talks BS
[09:03:00] <skunkworks_> He was trying to explain why linuxcnc was better than mach in one thread - got the thread locked I think..
[09:03:22] <syyl_ws> on the hsm board?
[09:04:09] <malcom2073> I love me a good linuxcnc vs mach thread, link? :P
[09:04:11] <skunkworks_> sounds right...
[09:04:17] <skunkworks_> heh
[09:04:24] <skunkworks_> it was a while ago..
[09:04:34] <syyl_ws> also always fun, inch vs. metric
[09:04:39] <syyl_ws> or digital vs. dial caliper
[09:04:46] <syyl_ws> or highspeedsteel vs. carbide
[09:04:50] <malcom2073> Heh
[09:04:51] <skunkworks_> right
[09:04:58] <syyl_ws> oh
[09:05:02] <syyl_ws> manual vs. cnc
[09:05:11] <archivist> use carbon steel for a good hand turning edge
[09:05:11] <FinboySlick> Well, I support his crusade against forceful Google+ ;)
[09:05:14] <syyl_ws> those are the best in my mind :D
[09:08:19] <skunkworks_> http://www.homemodelenginemachinist.com/showthread.php?t=18546
[09:10:37] <CaptHindsight> https://www.youtube.com/watch?v=MkrvUfLIoo4 MACH3 CNC GRINDER
[09:12:43] <CaptHindsight> is it actually possible to get the facts across of the differences of EMC vs Mach to the average user?
[09:13:02] <skunkworks_> depends on the user...
[09:13:22] <syyl_ws> uh
[09:13:23] <jdh> the average user will be using mach
[09:13:25] <syyl_ws> bob warfield
[09:13:31] <syyl_ws> i like that guy very much
[09:13:33] <syyl_ws> not
[09:14:33] <skunkworks_> bob does now have a tormach lathe running linuxcnc (with thier custom frontend) and has made comments on how much more stable it is than mach..
[09:15:12] <syyl_ws> that guy is like a flag in the wind
[09:15:17] <syyl_ws> turns 180deg every half hour
[09:16:24] <syyl_ws> and if some manufacturer drop something at his place, its automaticaly the best
[09:17:29] <syyl_ws> back then when he did just his blog with machining stuff he found in the net, that was interesting
[09:17:56] <cradek> man, these threads
[09:17:58] <Rab> Anybody investigated this project? http://www.rabidmantis.se/flexible-servo-controller/
[09:18:01] <cradek> why do I even
[09:18:16] <skunkworks_> cradek, you should know better!
[09:18:20] <syyl_ws> :D
[09:20:06] <malcom2073> skunkworks_: Thanks for the link, that's a riot :)
[09:20:55] <cradek> http://cdn.homemodelenginemachinist.com/images/panda.jpg
[09:21:08] <cradek> http://cdn.homemodelenginemachinist.com/images/oldlady2.jpg
[09:21:20] <cradek> these are the best part of that thread
[09:27:40] <malcom2073> heh
[09:38:34] <pcw_home> aww that make me feel so bad I will delete AB
[11:21:02] <jdh> https://www.youtube.com/watch?v=zbm2SSql8V8
[11:22:28] <archivist> jdh what about the 1960/70's PCBs IBM made by routing a wirepen
[11:22:37] <archivist> first...pfft
[11:25:05] <jdh> you would make a terrible marketing rep :)
[11:25:10] <archivist> hehe
[11:25:46] <archivist> I may have an example of the IBM technology knocking about somewhere
[11:26:03] <jdh> does it have a name/link/etc?
[11:26:29] <archivist> I just tried to google myself :)
[11:26:59] <malcom2073> Lol, first
[11:27:11] <malcom2073> 3d printing is a world of "first", most of which has been around for years
[11:27:17] <CaptHindsight> it's not the first
[11:27:21] <malcom2073> I see "first" at least once a day when looking through thigns.
[11:27:26] <malcom2073> things*
[11:27:45] <malcom2073> Saw someone using a sharpie on a plotter to make circuits, then UV etching
[11:27:59] <CaptHindsight> that one is really low res
[11:28:20] <malcom2073> There was a 3d printer that squirted out solder, that was nifty
[11:28:30] <CaptHindsight> http://jordanbunker.com/archives/41 Project: Conductive Ink
[11:28:42] <CaptHindsight> we use inkjet
[11:28:47] <CaptHindsight> have been for years
[11:28:58] <cradek> multilayer circuit boards are certainly not 2d as they state
[11:29:53] <malcom2073> CaptHindsight: Nice
[11:30:05] <jdh> hype aside, it is still interesting to me. I started CNC'ing to make PCB's
[11:31:00] <jdh> does anyone use somethign other than solder to connect components to boards? conductive glues or something?
[11:31:25] <CaptHindsight> yes, inks, pastes, ultrasonic welding etc
[11:32:38] <CaptHindsight> that Harvard project looks like another reprap offshoot
[11:33:02] <CaptHindsight> they probably should have contacted MIT :) , they are right down the street
[11:34:27] <CaptHindsight> taking the potentially useful and making it near useless, that takes talent
[11:37:47] <malcom2073> you'd think, but an amazing number of people are doing that nowadays
[11:38:14] <CaptHindsight> https://www.youtube.com/watch?v=ioSN2jG49Gw 6 Axis 3D Printing System slow but been around for a while
[11:39:12] <malcom2073> Wow that's uh....
[11:39:17] <CaptHindsight> http://vimeo.com/93968312
[11:39:33] <CaptHindsight> slow and expensive
[11:39:55] <malcom2073> Yes
[11:40:42] <CaptHindsight> it's just an aerosol nozzle on a robot or 5-axis system
[11:40:53] <malcom2073> That's an expensive eggbot
[11:41:07] <CaptHindsight> and yes they actually got a patent for an aerosol nozzle
[11:41:58] <archivist> I thought it was earlier, or IBM was extending http://patents.justia.com/patent/4662963
[11:42:37] <PetefromTn_> what was the point of that printing circuit boards on eggshells?
[11:44:36] <CaptHindsight> possible to show multiaxis, that they weren't cheating and it is conductive at room temp
[11:45:43] <CaptHindsight> http://www.3ders.org/articles/20140722-neotech-releases-new-system-for-3d-printing-electronics.html disingenuous to say "This system is capable of printing millions of parts per year." when it prints so slowly
[11:46:13] <malcom2073> 30 seconds per part
[11:46:17] <malcom2073> is one million parts per year
[11:47:17] <CaptHindsight> for the complete cycle time, not just printing
[11:47:17] <tjtr33> CaptHindsight, I see some 'blown powder laser deposition" where metal particles are blown into airstream around laser.
[11:47:18] <tjtr33> familiar? how does the process know when enuf material has accumulated, when to move on?
[11:47:33] <malcom2073> Yep, 24/7
[11:47:43] <CaptHindsight> tjtr33: like a laser printer
[11:47:56] <malcom2073> tjtr33: I saw that... there's an awesome video where it does that, and then mills th epart
[11:47:58] <malcom2073> Pretty cool looking
[11:47:59] <CaptHindsight> we do that with power coatings as well
[11:48:30] <CaptHindsight> with metal powder it's pretty predictable
[11:48:34] <tjtr33> so it assumes it's done, open loop? rates left up to operator?
[11:48:35] <CaptHindsight> the rate of build
[11:49:34] <CaptHindsight> you can control the amount of material deposited per unit of time
[11:49:39] <moorbo> CaptHindsight: thats prettty interesting
[11:49:56] <malcom2073> https://www.youtube.com/watch?v=s9IdZ2pI5dA
[11:49:58] <malcom2073> That's the one
[11:49:59] <moorbo> CaptHindsight: though, i wish someone spent some money on a tripod to hold the camera
[11:50:17] <CaptHindsight> this mostly what I work on using Linuxcnc for motion control
[11:50:39] <tjtr33> i was looking at the impala project https://www.youtube.com/watch?v=fQjgHszJVLs
[11:51:04] <malcom2073> tjtr33: Looks similar
[11:51:09] <tjtr33> yah
[11:51:37] <CaptHindsight> all with patented nozzle designs
[11:51:58] <malcom2073> Of course
[11:52:02] <CaptHindsight> so it won't go very far in the west for 20 more years
[11:52:09] <tjtr33> patent = "my nozzle has a hole in it"
[11:53:06] <CaptHindsight> yup, or the gas regulation in the nozzles, or the atomizer behind it etc etc
[11:53:07] <malcom2073> I don't know if that sort of thing will ever be home-shop level anyway, but it's a cool idea
[11:53:18] <CaptHindsight> oh yeah it can be
[11:53:30] <CaptHindsight> fancy airbrush
[11:53:59] <tjtr33> hand held laser and sand box of carbide dust
[11:54:12] <CaptHindsight> as the parts made in China drive the prices down you'll be able to DIY them
[11:54:22] <CaptHindsight> laser prices are falling
[11:54:31] <tjtr33> skylab!
[11:54:35] <malcom2073> They are, almost low enough that I want to get a laser cutter
[11:54:38] <CaptHindsight> same for UV - Blue LED's
[11:54:39] <malcom2073> well... "etcher"
[11:55:15] <jdh> be careful with home laser use.
[11:55:42] <CaptHindsight> I was at a conference in Beijing 2 years ago. They asked me about what metal powders they should make
[11:56:14] <malcom2073> jdh: I've worked with non-eyesafe lasers before, you'd better believe I'd overkill on safety heh
[11:56:25] <malcom2073> "Do not look into laser with remaining eye"
[11:56:42] <jdh> I really meant burning down your house and having to live in an airplane hangar
[11:56:57] <CaptHindsight> titanium starts around $9/lb
[11:57:07] <malcom2073> Oh, well yeah heh
[11:57:30] <CaptHindsight> by the time 3d printer co's sell it as powder it's in the $hundreds/lb
[11:57:33] <tjtr33> uv is used to cure resin, right? can a form be in the resin bath, and the laser trace over the form? thinking medical prosthesis
[11:57:48] <jdh> like inkjet ink
[11:58:04] <CaptHindsight> yeah, UV or visible
[11:58:29] <CaptHindsight> a projector can cure an entire layer in <1 second
[11:59:05] <CaptHindsight> 100um XYX rez
[11:59:27] <tjtr33> cna it work like a 2 shot mold ( like the key caps on your keyboard, thats 2 runs thru 2 diff molds )
[11:59:27] <CaptHindsight> XYZ even
[12:00:04] <CaptHindsight> I'm placing metal inserts into photopolymer printers
[12:00:29] <_methods> ahhh so keycaps are a 2 shot mold
[12:00:42] <_methods> i got a buddy askin me to make key cap molds for him
[12:01:32] <CaptHindsight> you can DMLS the metal, then SLA resin over that and inkjet on that as well
[12:02:09] <tjtr33> can SLA work over, say organic stuff? an orange slice?
[12:02:29] <CaptHindsight> sure
[12:02:59] <jdh> orange slice keycaps?
[12:03:20] <tjtr33> nice molds then, from real parts ( plaster casters return )
[12:03:32] <CaptHindsight> the reason you don't see these types of printers here is that the 3d printer co's don't share
[12:03:58] <CaptHindsight> one has the patent on metal sintering, another on plastic, another on SLA etc etc
[12:04:10] <syyl> but no one on pizza :(
[12:06:18] <CaptHindsight> here you just mostly hear about the stupid glue guns
[12:10:42] <malcom2073> Did you see someone made a 3d printer out of an actual hobby glue gun?
[12:10:47] <malcom2073> It was as bad as it sounds
[12:10:48] <CaptHindsight> tjtr33: going to start printing laptop and phone cases
[12:11:10] <malcom2073> That being asid, I like my glue gun :P
[12:12:44] <tjtr33> CaptHindsight, bunnies case? http://www.bunniestudios.com/
[12:12:44] <CaptHindsight> http://www.3ders.org/articles/20141227-google-says-3d-systems-3d-printer-not-ready-for-project-ara-modular-smartphones.html this is the other problem with the patent holders, they can't actually make their printers work as promised
[12:13:08] <CaptHindsight> tjtr33: he's injection molding
[12:13:42] <tjtr33> yah bou gonna DLP / SLA that design? lemme know, i'd build one
[12:13:47] <tjtr33> you
[12:14:33] <malcom2073> Heh, never ceases to amaze me
[12:17:40] <CaptHindsight> tjtr33: you can SLA these tooless (the plastic) vs insert molding
[12:18:03] <zeeshan|2> CaptHindsight: have you operated a sla printer
[12:18:23] <CaptHindsight> a game changer for low-mid volume
[12:18:39] <CaptHindsight> zeeshan|2: I design them
[12:18:58] <CaptHindsight> and make the photopolymers
[12:19:18] <zeeshan|2> i gotta operate one started feb
[12:19:24] <zeeshan|2> im gonna f around with it
[12:19:30] <CaptHindsight> which model?
[12:19:35] <zeeshan|2> i dont know yet
[12:19:38] <zeeshan|2> maybe will find out tomorrow
[12:19:55] <zeeshan|2> i just know its sla :P
[12:20:23] <CaptHindsight> most use a single laser and >$150/lb resin
[12:22:18] <zeeshan|2> yea
[12:22:22] <zeeshan|2> sla is expensive :P
[12:22:30] <zeeshan|2> i think its a powder?
[12:22:35] <zeeshan|2> that you load up
[12:22:39] <zeeshan|2> not a resin
[12:23:37] <FinboySlick> zeeshan|2: isn't sla supposed to be resin?
[12:23:53] <zeeshan|2> maybe its DLP
[12:23:54] <zeeshan|2> i dont know
[12:23:54] <zeeshan|2> ahha
[12:24:01] <zeeshan|2> i know it doesnt use plastic spools :P
[12:24:01] <[cube]> maybe an objet?
[12:24:08] <zeeshan|2> it uses some sort of powder
[12:24:33] <FinboySlick> zeeshan|2: It's probably the inkjet type then.
[12:25:15] <FinboySlick> zeeshan|2: They can be pretty cool and do colors. Though most materials aren't amazing mechanically.
[12:26:23] <zeeshan|2> cool :D
[12:28:05] <zeeshan|2> servo experts
[12:28:17] <zeeshan|2> i've been trying to decode these ratings on both my motors and am quiet confused
[12:28:19] <zeeshan|2> https://www.flickr.com/photos/128539016@N05/14912261923/in/photostream/
[12:28:19] <zeeshan|2> and
[12:28:23] <zeeshan|2> https://www.flickr.com/photos/128539016@N05/14912262293/in/photostream/
[12:28:29] <zeeshan|2> first motor is x,y
[12:28:30] <zeeshan|2> second is z
[12:28:42] <zeeshan|2> can you tell what the locking rotor current is
[12:28:57] <zeeshan|2> and continuous running current is
[12:29:04] <zeeshan|2> and peak current ? <- i dont think this rating is there
[12:29:12] <zeeshan|2> i see there amperage ratings on the damn plate.
[12:29:15] <zeeshan|2> *three
[12:29:29] <CaptHindsight> zeeshan|2: if it uses powder it's either SLS, (laser sinter) or inkjet with binder
[12:29:42] <zeeshan|2> 7.5A @ 190V, then some random I_o 6.4A , and I_o_max 7.0A
[12:29:46] <CaptHindsight> inkjet with binder gets you 4 color process
[12:30:14] <zeeshan|2> and 13.6A@173V, I_o 13.8A, I_o_max 15.3A
[12:30:22] <zeeshan|2> CaptHindsight: ah okay
[12:30:29] <CaptHindsight> it's a fancy HP45 thermal inkjet printer
[12:30:43] <CaptHindsight> prints 4 color glue on powder

[13:54:45] <zeeshan|2> anyone make one of these?
[13:59:30] <Rickta59> anyone buy a printrbot from adafruit? Seems to offer free shipping and free stuff ( trinket pro, trinket mini breadboard) ?
[14:04:50] <archivist> zeeshan|2, in here we cnc cut cookies!
[14:05:03] <zeeshan|2> i need a cookie cutter type thing
[14:05:11] <zeeshan|2> to chop out some tensile test samples for polymers
[14:06:01] <archivist> I need the washing machine not to clog up once or twice a year
[14:06:11] <zeeshan|2> lol
[14:06:47] <archivist> 2 hours to move the thing outside to empty and clear it, drag it back in
[14:07:27] <zeeshan|2> i had sand trapped in mine
[14:07:33] <zeeshan|2> was a royal pain in the ass
[14:07:43] <archivist> this had grit and fluff
[14:08:13] <zeeshan|2> one big mistake i made was watchibg beach clothes in there :P
[14:09:14] <archivist> trivial to bend up some cutters
[14:09:26] <zeeshan|2> they gotta be accurate
[14:09:28] <zeeshan|2> to 1 thou though
[14:10:07] <archivist> methinks the materiel you are cutting is not though
[14:12:05] <zeeshan|2> http://turbozee84.imgur.com/all/
[14:12:09] <zeeshan|2> was thnking of doing it like that
[14:12:12] <zeeshan|2> mill out a pocket
[14:12:27] <zeeshan|2> then run a 45 degree cutter along the edges
[14:13:37] <archivist> turbozee84's images are not publicly available
[14:13:45] <zeeshan|2> http://i.imgur.com/VHlH7jh.png
[14:13:50] <zeeshan|2> actually i dont think i can do it like this
[14:13:58] <zeeshan|2> cause i cant make the sharp corners inside
[14:14:05] <zeeshan|2> i'll need to chamfer from both sides
[14:14:43] <archivist> probable needs to be sharper
[14:17:07] <zeeshan|2> or i should just call it a day
[14:17:16] <zeeshan|2> and use a sharp knife and trace out a metal cut sample :)
[14:17:19] <zeeshan|2> and do it by hand
[14:17:19] <zeeshan|2> haha
[14:24:33] <zeeshan|2> http://www.homedepot.ca/product/15-amp-250v-single-receptacle-ivory/903694
[14:24:37] <zeeshan|2> im going to be installing one of these soon
[14:24:39] <zeeshan|2> first time!
[14:24:42] <zeeshan|2> so weird looking.
[14:25:29] <archivist> horrible US plug
[14:25:33] <zeeshan|2> haha
[14:25:34] <zeeshan|2> i know :P
[14:25:50] <zeeshan|2> its a lot more compact :)
[14:26:04] <zeeshan|2> uk plugs are kinda huge
[14:26:53] <archivist> try unplugging one of these :) http://www.jhmbuttco.com/acatalog/info-RAV64AMP5PIN.html
[14:27:25] <zeeshan|2> fancy :)
[14:27:44] <jdh> z: why the funky plug?
[14:28:04] <zeeshan|2> jdh the manual mill i got uses a weird 240v plug
[14:28:21] <zeeshan|2> and this is the most common one
[14:28:35] <jdh> I've never seen one of those.
[14:28:48] <zeeshan|2> you must not have 220v loads :P
[14:29:13] <jdh> we don't plug in a lot of thigns like that, but I've seen lots of 220v plugs.
[14:29:31] <archivist> some made their way over here on american stuff
[14:29:45] <jdh> but I have never seen one of those.
[14:30:01] <zeeshan|2> http://www.dontscrapit.com/Nevada-/Commercial-/Eagle-receptacle-220V-surface-mount-with-2-pole-and-3-partpic.jpg
[14:30:04] <zeeshan|2> these are the more common ones
[14:30:07] <zeeshan|2> theyre 50A plugs though
[14:30:34] <archivist> looks more like 5A
[14:30:43] <zeeshan|2> ??
[14:30:44] <zeeshan|2> its huge
[14:31:15] <archivist> bare metal screw between pins
[14:31:50] <zeeshan|2> that screw goes into plastic
[14:31:51] <zeeshan|2> not metal
[14:32:04] <zeeshan|2> i guess you can have a phase to phase short :P
[14:45:19] <CaptHindsight> http://www.signalandpower.com/images/original/yp-97l.jpg
[14:51:29] <Tom_itx> zeeshan|2, iirc the 20A ver has a T on one side of the receptacle
[14:51:46] <Tom_itx> instead of the - - arrangement
[14:52:19] <zeeshan|2> http://www.homedepot.ca/wcsstore/HomeDepotCanada/images/catalog/15767.174840_4.jpg
[14:52:22] <zeeshan|2> this one is 20amp
[14:52:27] <zeeshan|2> the - - is 15
[14:52:35] <zeeshan|2> | - i guess is 20?
[14:52:43] <zeeshan|2> prolly some nema 6 standard
[14:53:14] <Tom_itx> yep
[14:53:42] <Tom_itx> so the 15 plug will still fit i think but 20A won't fit a 15
[14:53:52] <zeeshan|2> yes
[14:57:44] <zeeshan|2> looks like 1.5 hp draws 10A at 230V
[14:57:59] <zeeshan|2> so i think a 15 a breaker might be better than 20a cause it might act like an overload :P
[14:58:18] <Tom_L> need a job? http://www.electronicproducts.com/Industrial/Business/The_16_best_tech_companies_to_work_for_in_2015.aspx
[15:00:02] <zeeshan|2> ge aviation is up there
[15:00:02] <zeeshan|2> nice.
[15:00:30] <Tom_itx> powerplants
[15:01:47] <FinboySlick> Bose shouldn't be so nice with their employees though, I think they've been slacking off for the last 30 years ;)
[15:03:28] <CaptHindsight> 7. Apple Rating – 4.0; Paradise of jobs
[15:05:24] <FinboySlick> Most of the people I know who worked there said the culture was: "Put up 'cause there's 1000 people dreaming to take your place."
[15:05:59] <Tom_itx> damn yuppies
[15:06:05] <CaptHindsight> http://3dprintingindustry.com/2014/10/13/ge-3d-printed-leap-engines/
[15:06:46] <CaptHindsight> how do they actually measure Best?
[15:07:33] <CaptHindsight> happiest employees, least number of suicides on Monday, number of applicants waiting to take your place?
[15:09:35] <zeeshan|2> sanity check
[15:09:43] <zeeshan|2> 15.2 A 3 phase 5hp motor
[15:09:52] <zeeshan|2> 12 awg good enuf? :p
[15:10:08] <zeeshan|2> vfd cable is stupid expensive as it gets more thicker
[15:10:10] <zeeshan|2> more so than regular cable
[15:10:40] <alex____w> my gut feeling is that 12awg is small
[15:10:56] <alex____w> but my gut these days is around sizing dc cables, not ac cables
[15:11:00] <alex____w> so it's likely poorly tuned
[15:14:17] <zeeshan|2> i just measured fthe wires in the cable that came wit hthe machine
[15:14:35] <zeeshan|2> .058" diameter
[15:14:55] <zeeshan|2> looks like its between 15 and 16 gauge lol
[15:17:15] <CaptHindsight> http://www.encorewire.com/wp-content/uploads/wire-size-table-CU.png what's allowable by code depends on the type of insulation as well
[15:17:34] <zeeshan|2> ofcourse
[15:17:39] <zeeshan|2> that table isn't derated though
[15:17:56] <zeeshan|2> for example if you look at 90C thhn.. (typical house wiring)
[15:18:04] <zeeshan|2> it says 25 amps for 14 awg..
[15:18:21] <CaptHindsight> you didn't mention the insulation type or the type of conductor
[15:18:44] <zeeshan|2> CaptHindsight: cause not many people run anything but 90 c cable these days :)
[15:18:46] <jdh> 12awg
[15:19:01] <zeeshan|2> 14 awg for residential is standard for 15A
[15:19:18] <jdh> residential isn't a motor
[15:19:21] <CaptHindsight> #14 THHN
[15:19:58] <alex____w> residental code for 15a motor is 12awg, 14awg is for a fixed load
[15:20:01] <CaptHindsight> in conduit, it would be valled out differently for romex
[15:20:01] <alex____w> if i remember correctly
[15:20:18] <CaptHindsight> valled/called
[15:20:20] <zeeshan|2> alex_jon1: thats singl;e phase
[15:20:22] <zeeshan|2> not 3 phase
[15:21:20] <alex____w> yes, that is true too
[15:21:21] <CaptHindsight> but I'm sure that any #12 that you get your hands on will be fine other than 90 year old recovered cloth covered
[15:21:32] <zeeshan|2> haha
[15:21:45] <tjtr33> damn laptop hinges so tight the case cracked. pulled out the brass sleeve and its too free now. looks like i backyard eng a coathanger rear support.
[15:21:47] <alex____w> my 1.5hp vfd motor is wired with 10 awg
[15:21:59] <alex____w> just what it came with, so it could be overkill
[15:22:18] <CaptHindsight> tjtr33: what model?
[15:22:24] <tjtr33> hey i got that 12ga cloth covered, buts its solid and comes with the ceramc posts standoffs
[15:24:11] <CaptHindsight> heh, it's always fun to have to tap into those, every time you touch them they disintegrate
[15:24:30] <alex____w> all of the knob and tube is finally out of our house
[15:24:56] <tjtr33> CaptHindsight, Gateway MT6730 ( had to lshw to find out )
[15:25:31] <tjtr33> the scary bit is the burn marks, which usually are where the wires were soldered then wrapped
[15:26:58] <zeeshan|2> http://www.igus.com/iPro/iPro_01_0013_0016_USen.htm?c=US&l=en
[15:27:02] <zeeshan|2> wow this is some sexy cable.
[15:29:26] <tjtr33> CaptHindsight, hurry & print me a new case ;)
[15:31:16] <CaptHindsight> tjtr33: heh, create a 3d model of the case
[15:32:30] <tjtr33> hm, fuzzy jpg of cracked ase not good enuf?
[15:33:38] <tjtr33> this may be a good time to really use a glue gun. big lump on rear so top doesnt fall over
[15:35:30] <CaptHindsight> maybe epoxy putty
[15:36:22] <CaptHindsight> I'm mixing some today that is like pulling taffy at room temp
[15:40:30] <CaptHindsight> http://www.tomshardware.com/news/thinkpad-laptop-hinge-testing-durability,11970.html
[15:52:10] <zeeshan|2> where to get thhn cheap!
[15:54:31] <mrsun> exchanged some delrin "bearings" for some real roller bearings on the machine today .. damn its alot smoother =)
[15:54:34] <mrsun> ALOT smoother =)
[15:58:34] <Connor> Freaking Water Heater in the RV SUCKS!
[15:58:57] <Jymmm> This looks like SO much fun… https://www.youtube.com/watch?v=qhIF-7UPDCw
[15:59:50] <Jymmm> Connor: You can find these for $99 This looks like SO much fun… https://www.youtube.com/watch?v=qhIF-7UPDCw
[15:59:52] <Jymmm> bah
[16:00:02] <Jymmm> Connor: http://www.overstock.com/Home-Garden/Portable-Tankless-Propane-Water-Heater/7485094/product.html?refccid=UOMUGGUHWCXKH3CFRLVI4PC4D4&searchidx=1
[16:00:30] <Jymmm> Connor: completely portable, hok to a garden hose and 20lb propane tank
[16:00:40] <Jymmm> needs two D batteries
[16:03:58] <Connor> Can that be used INSIDE ?
[16:04:36] <CaptHindsight> Outdoor installation only
[16:04:43] <Connor> Yup, Just saw that.
[16:04:54] <CaptHindsight> Needs 30-80 PSI of water pressure
[16:04:54] <CaptHindsight> Low flow rate start (0.5 GPM / 1.3 LPM)
[16:05:53] <CaptHindsight> 37,500 BTU's ! how did they measure that?
[16:06:17] <CaptHindsight> bet it's Chinese BTU's
[16:07:07] <Connor> I guess we could run the water hose into it.. and then out and through the bedroom window into the shower..
[16:08:27] <CaptHindsight> A BTU is the amount of heat required to raise the temperature of 1 avoirdupois pound of liquid water by 1 degree Fahrenheit at a constant pressure of one atmosphere. = 1055 joules or 1055 watt-seconds
[16:09:13] <CaptHindsight> 37500 x 1055 = ~40MJ
[16:10:02] <Deejay> gn8
[16:10:35] <CaptHindsight> that thing should shoot superheated steam out
[16:39:57] <Jymmm> Connor1: you cn get/use a 12Vpump too
[16:40:29] <Connor> Jymmm: How does that help ?
[16:40:49] <Jymmm> Connor: If you are pulling from the holding tanks instead of faucet
[16:40:56] <Connor> Oh.
[16:41:30] <Jymmm> Connor: here it is, the L10 that is... https://www.youtube.com/watch?v=HcY2nW05Kvs
[16:41:40] <Jymmm> I linked you to the L5 iirc
[16:46:24] <Jymmm> Connor: Here is the L5... https://www.youtube.com/watch?v=jbnpiehO1nQ
[16:50:50] <Jymmm> Connor: IIRC the shower head has an on/off switch too.
[16:51:05] <Jymmm> Connor: Just a potential solution ;)
[16:53:27] <Jymmm> Connor: L5 + flowjet pump... https://www.youtube.com/watch?v=OwLtFXET0Zo
[16:55:49] <Connor> Problem is getting the water into the RV shower since it has to be outside.
[16:56:08] <Jymmm> No roof vent?
[16:56:26] <Connor> Yea, We have one in the Front, one in the bedroom, and one in the overcab.
[16:56:45] <Jymmm> Connor: You could reverse feed it thru the existing hot wire lines
[16:56:52] <Jymmm> hot water lines *
[16:57:17] <Jymmm> Connor: Does the existing hot water heater no good?
[16:57:30] <Jymmm> or just poor
[16:57:40] <Connor> It heats, but, it's very very luke warm.
[16:57:50] <Jymmm> Ah, small tank.
[16:57:55] <Connor> 6 gallon.
[16:58:06] <Jymmm> Connor: Is there room to plumb in a spikot?
[16:58:31] <Connor> Not sure. I have access to the water lines on the inside under the stove.
[16:58:51] <Jymmm> Connor: but can you feed hot water into an exterior panel?
[16:59:18] <Connor> We have fresh water hookup if that's what your asking.
[16:59:29] <Jymmm> No I mean the hot water side
[16:59:33] <Connor> No.
[16:59:39] <Connor> Just cold only.
[16:59:48] <Jymmm> OH... does the existing hot water heater have a drain valve?
[17:00:08] <Connor> Umm.. I think it does.
[17:00:19] <Jymmm> There ya go, reverse feed it thru that
[17:00:27] <Connor> Let me go look at that.
[17:00:28] <Connor> brb
[17:00:44] <Jymmm> you might have to shut off the cold water supply to the HWH though
[17:02:39] <Jymmm> Connor: As a quick test, you can use plastic garden fittings if you have them. But if you don't already have them. Spend the money on brass fittings, it will be WELL WORTH IT. Don't ask me how I know this ;)
[17:04:55] <JT-Shop> if you have hot water why do you need to heat it
[17:05:13] <Jymmm> JT-Shop: only has a 6gal tank
[17:05:44] <JT-Shop> what does size have to do with the equation?
[17:06:01] <Jymmm> Connor: Also, this is rubber hose and meant to be used with hot water http://www.homedepot.com/p/Apex-5-8-in-dia-x-25-ft-Red-Rubber-Commercial-Hot-Water-Hose-8695-25/202900081
[17:06:15] <Jymmm> JT-Shop: In a RV, the tank size related to water temp
[17:06:45] <Tom_itx> stop taking 20 min showers!
[17:06:51] <Jymmm> JT-Shop: they are very ineffiant
[17:07:05] <JT-Shop> but the water is hot, why heat it?
[17:07:10] <Jymmm> Tom_itx: HA you could NEVER take a 20m shower... EVER
[17:07:22] <MC500> My computer died and I bought a new one with an ISA slot now EMC does not work at all... I am using EMC 2.3 for my ISA STG card, what version should I upgrade to before diving into why it doesent work?
[17:07:25] <Jymmm> JT-Shop: IT's luke water from their existing HWH
[17:07:52] <JT-Shop> so it's not a hot water heater, but a cold water heater
[17:08:14] <Jymmm> Connor: Crap, that hsoe is online only. But look for HOT WATER rubber hoses, they last forever
[17:08:38] <Tom_itx> hose from a cement truck
[17:08:44] <Tom_itx> those are pretty rugged
[17:09:00] <Jymmm> Yeah, I have two cement trucks right here, let me grab a hse
[17:09:03] <Tom_itx> i had some like that made when i did my basement
[17:09:05] <Jymmm> hose
[17:09:14] <Tom_itx> local rubber supply had it
[17:09:45] <Jymmm> he wants hot water, not $400 hose =)
[17:10:00] <Tom_itx> it wasn't $400
[17:10:10] <JT-Shop> w;hy not $400
[17:10:21] <Tom_itx> and how bad _does_ he want it?
[17:11:38] <JT-Shop> I'd say a hot shower in 10F is worth $400
[17:12:46] <JT-Shop> heating hot water seems like a waste of energy to me
[17:14:15] <Tom_itx> cold showers take much less time anyway
[17:14:51] <Jymmm> JT-Shop: You know, your HWH is now going to go out on you for saying that
[17:15:29] <jthornton> my water heater only heats cold water
[17:15:49] <_methods> hahahha
[17:15:54] <Jymmm> Well, it's gonna heat NOTHING 20 minutes before you want it to
[17:16:09] <Connor> what about running hot water line from the HOUSE ? My hotwater heater is in the shop which has a flap I can run hose out.
[17:16:44] <Jymmm> Connor: Sure, just drain it for sediment before connecting it to the RV
[17:17:07] <_methods> jthornton: you just made my day
[17:17:10] <Connor> Hmm..
[17:17:42] <Jymmm> Connor: The bottom of AL HWH have sediment build up. That's what that lower faucet is for =)
[17:18:02] <Connor> No. I would use the upper one.
[17:18:04] <Jymmm> Connor: DO NOT TOUCH the safety release valve though.
[17:19:06] <Connor> I have a connect for the clothes washer in that room.. direct off the hot.
[17:19:26] <Connor> clothes washer no longer in the shop.. it in 2nd bathroom in house now.. :)
[17:19:34] <Jymmm> Connor: Fine, just use a 50ft HOT WATER HOSE
[17:19:47] <Connor> ok. wonder how much of a temp drop I'll get...
[17:19:49] <Jymmm> Connor: not a standard garden hose
[17:20:06] * jthornton is glad someone understood what I was saying
[17:24:43] <_methods> heheh
[17:24:50] <_methods> my wife got a kick out of it too
[17:25:14] <_methods> she's like why the f*** are you laughin so hard
[17:25:58] <jthornton> lol
[17:26:46] <Tom_itx> jthornton, you don't preheat your hotwater?
[17:27:01] <jthornton> nope
[17:28:32] <_methods> hehe lazy heater
[17:28:35] <jthornton> if I had an outside wood boiler I would have free hot water
[17:28:52] <jthornton> free as in it would not cost anything but labor
[17:29:35] <jthornton> unfortunately one of those would not pay off before I am too old to cut firewood
[17:33:23] <Tom_itx> jthornton, reverse your moonshine coil :)
[17:33:44] <jthornton> shhhh
[17:36:56] <Tom_itx> jthornton, what OS do you run solidworks on?
[17:36:59] <Tom_itx> 7?
[17:37:45] <jthornton> hmm 7 I think
[17:37:51] <jthornton> it's out in the shop
[17:38:10] <Tom_itx> i noticed newer versions won't run on xp
[17:38:19] <Tom_itx> probably a 64bit thing?
[17:39:22] <jthornton> I have 2010 on my XP computer down here in the beer cave

[18:47:37] <Nick001-shop> Is there any decent info on converting a Bridgeport series 1 Boss4 to Linuxcnc?
[18:47:42] <Bushman> heh, drawer sliders :D
[18:47:50] <Bushman> i have some of those too :D
[18:48:41] <Bushman> suprisingly good enough for homemade CNC :P
[18:49:22] <Bushman> but to be honest i need to buy one more 16mm rail and bearings and replace this axis
[18:49:57] <Bushman> it's nice for wood but there are visible marks on acrylic :P
[18:50:43] * Bushman is lazy and procrastinates designing metal version of his homemade CNC
[19:28:00] <Bushman> i'm attempting to install AXIS in simulator mode on my laptop...
[19:28:26] <Bushman> i'm going to regret that, am i not?
[19:32:52] <Jymmm> 4steaks from costco... $1199.99 USD
[19:33:32] <_methods> gold steaks
[19:34:35] <malcom2073> Costco: Where stuff really costs.
[19:39:03] <XXCoder> 1199 bucks for 4 steaks? I call bullshit
[19:40:49] <_methods> each steak weighs 100 lbs
[19:43:53] <malcom2073> mmmm steak
[19:44:19] <XXCoder> 100 lb jeez thats thick steak
[19:44:42] <XXCoder> "where's the table?" "under your steak!"
[19:46:35] <CaptHindsight> http://www.costco.com/D%E2%80%99Artagnan-Japanese-Wagyu-Boneless-Ribeye-Roast-A-5-Grade.product.100082950.html $136/lb
[19:47:40] <XXCoder> expensive
[19:47:46] <XXCoder> too bad its not worth it for me
[19:47:59] <Tom_itx> it's bull not steak
[19:48:14] <malcom2073> Also not Japanese, or Wagyu
[19:49:03] <CaptHindsight> Six 3lb Live Maine Lobsters $269.99
[19:49:11] <CaptHindsight> http://www.costco.com/Six-3lb.-Live-Maine-Lobsters-By-Atwood-Lobster-.product.100019109.html
[19:51:23] <malcom2073> Guy I know used to drive a tractor trailer with lobsters from maine down to florida
[19:51:33] <malcom2073> he used to stop by on his way and sell me a few, back before I was allergic :/
[19:54:03] <CaptHindsight> Two 12-oz. ribeyes $200 http://www.deandeluca.com/butcher-shop/beef/wagyu-beef/wagyu-ribeyes.aspx
[19:59:47] <Bushman> does that work reliably? http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Shift_Register_Port_Expander
[20:36:08] <CaptHindsight> Bushman: if the pcb is properly designed and assembled
[20:43:04] <Bushman> that is not an issue. i think i'll use that for my end stops and home switches then
[20:43:42] <Bushman> that way i might even be able to spare a direct bit or two for other stuff
[20:59:45] <MC500> I am trying to get a new computer to work with my stg card and Linux CNC 2.6 for some reason the servo's dont move any axis
[21:00:04] <MC500> im using all the old configuration files from EMC 2.3
[21:01:08] <Tom_itx> i'm guessing there have been config changes since 2.3; you might want to look at that
[21:01:38] <MC500> I tried diffing the files I didnt see much
[21:02:07] <MC500> only major differance is new file does not use emc.nml
[21:02:10] <Bushman> MC500: i have absolutely no idea what's your hardware setup but if i was you i'd try to manually configure at leat one axis and test it first. then look for issues with your old configs
[21:06:17] <MC500> other than flipped bits on limit switches not much
[21:07:00] <MC500> what was emc.nml?
[21:07:59] <Bushman> i don't know. maybe someone else does.
[21:08:27] <Bushman> but did you try to manually configure at least one axis and see if things work together?
[21:09:11] <MC500> well I had one axis run away each time I started it so I left it out now I got the rest homed and green but nothing I do to tuning makes it move at all
[21:09:11] <Bushman> don't configure anything else, just one thing to prove to yourself that the card and software do what you think the should do
[21:09:30] <MC500> if I enable the amplifier I do feel resistance on the lead screw
[21:09:47] <Bushman> what is your config?
[21:09:52] <MC500> the scales all work fine
[21:10:05] <MC500> stg.ini for the most part
[21:10:07] <Bushman> printer port + some stuff on the card or just the card?
[21:10:16] <MC500> just the card
[21:10:25] <MC500> its at base address 240
[21:10:37] <MC500> nothing else is there but to my supprise there is no irq used
[21:10:58] <Bushman> was it used before?
[21:11:20] <MC500> not that I am aware of
[21:11:25] <MC500> STG: Initialised stg2 card at address 240
[21:11:47] <MC500> I disabled anything and everyting in the MB bios that took an irq
[21:11:48] <Bushman> do you have any means to test if the bits do what you tell them?
[21:12:19] <MC500> not sure how to do that
[21:12:23] <Bushman> if you say the amps are on that means some bits must be working
[21:12:51] <MC500> yea amps are on they reset scales work, coolant turns on and off spindle spins
[21:12:57] <Bushman> i don't have a card (yet) so i'm not really sure how one confugures it for use with linuxcnc
[21:13:12] <MC500> I have an old old old card ISA....
[21:13:30] <Bushman> so basically everythign works but not the axis?
[21:13:33] <Bushman> movement?
[21:13:36] <MC500> yea
[21:13:43] <Bushman> hmm...
[21:14:18] <Bushman> your stepper drivers are serial in or do you use multiple pins for each stepper?
[21:14:36] <MC500> its a/c amplifier a/c serveo
[21:15:10] <Tom_itx> http://www.linuxcnc.org/docs/2.4/html/drivers_servo_to_go.html
[21:15:16] <Tom_itx> 2.4 docs on it
[21:16:35] <Bushman> MC500: i mean does it use "direction" and "step" pins or multiple pins for each winding?
[21:17:01] <Bushman> also, do you have osciloscope? or multimeter atleats?
[21:18:39] <MC500> I can dig u p an o-scope but multimeter yes
[21:19:31] <Bushman> hook it up to direction pin
[21:19:43] <Bushman> and see if it changes depending which way you jog
[21:20:11] <MC500> ok will do that, thanks.. (have to read to figure out which one its been years...)
[21:20:22] <Bushman> then set extremely slow speed and test the step pin or use osciloscope
[21:21:25] <pcw_home> sounds like the analog outputs are not working (you could trace the signal in hal)
[21:21:27] <pcw_home> ( I'm assuming the STG card is +-10V analog output/encoder input card )
[21:21:41] <Bushman> on unrelated note: i've managed to install and run AXIS in simulator mode on my laptop :D
[21:22:14] <Bushman> no need to move my lazy ass, turn on the machine's PC and download files to just "see how it looks like"
[21:23:08] <MC500> was hoping for some kind of compatibility problem, it does work with the old computer which is very old and dosent even turn on from time to time.. but working
[21:24:16] <pcw_home> It works on the old machine with new software?
[21:24:27] <MC500> no its EMC 2.3
[21:24:59] <pcw_home> more likely a software issue if any I/O works
[21:25:15] <MC500> although I tred EMC2.3 on the new machine and it had the same issues I was just trying 2.6 because I thought since it was a newer machine might need new software
[21:25:53] <Bushman> EMC sounds like ancient history to me... the config file might "look" the same but i wouldn't bet on the software does the same anymore
[21:26:25] <pcw_home> Might be an I/O overlap (some MB hardware on top of the cards I/O)
[21:26:34] <Bushman> MC500: can't you try and manually reconfigure it from scratch?
[21:27:25] <MC500> I coppied every file form the new sample config except stg.ini and stg_io.hal
[21:27:44] <MC500> both those files look reasonable when compaired to the new samples
[21:28:01] <MC500> only a few bits flipped for limit switches and an added 4th axis
[21:28:55] <pcw_home> So does the exact same config work on one machine but fail on the other?
[21:29:13] <pcw_home> (swap drive only)
[21:31:24] <MC500> no, new PC does not work with old OS/EMC or new EMC
[21:33:09] <pcw_home> tough to find a relatively modern MB with ISA
[21:34:15] <pcw_home> so you newer MB wont work with the current debian ISO?
[21:36:48] <MC500> whats the current one, I had 2.6 figured it was new enough
[21:37:39] <furrywolf> pcw: happen to have a used 7I76E? I got a few bucks spare (taxes were cheaper than I expected... only sent uncle sam $1720 today!), and am reconsidering a mesa board...
[21:37:43] <MC500> its a farily modern board its a Core2 quad
[21:38:54] <MC500> it was like $500.00 to get freaking ISA... had dual NICS on board graphics 4 serial ports bla bla bla
[21:43:50] <MC500> well I have got to go, thanks for everyones help.. I will scroll back later if anyone posts follup info... ttl
[21:44:05] <PetefromTn_> evening folks...
[21:44:18] <furrywolf> mc500: I'll send you my isa gpib card nice and cheap. :P
[21:45:05] <PetefromTn_> about to setup the little 5C spindex I bought for a CNC job for the first time LOL
[21:45:25] <PetefromTn_> I am thinking I will make some simple mods to it
[21:46:26] <PetefromTn_> https://www.youtube.com/watch?v=Ns0I8TKdZrQ Don't need to turn it into a dividing head like he is but It would be nice to be able to clamp it in the vise longitudinally and be parallel with it's spindle
[21:47:38] <PetefromTn_> so probably gonna do that tonight or tomorrow morning before I start the programmed cuts..
[21:48:01] <t12_> http://en.wikipedia.org/wiki/Torpedo_Data_Computer
[21:48:26] <furrywolf> I started working on straightening my bent shaft today... didn't get very far. promptly ran out of oxygen.
[21:48:47] <furrywolf> got the rough bend out, but ran out of oxy reheating for the fine tuning.
[21:48:51] * Jymmm LMAO @ furrywolf
[21:49:03] <furrywolf> ?
[21:49:18] <Jymmm> furrywolf: Ask your doctor if Viagra is right for you
[21:49:45] <furrywolf> ?
[21:50:02] <Jymmm> furrywolf: furrywolf: I started working on straightening my bent shaft today... didn't get very far. promptly ran out of oxygen.
[21:50:50] <Jymmm> furrywolf: phalic symbol and somethign you need to breath
[21:50:52] <furrywolf> jymm: http://fw.bushytails.net/bentleadscrew01.jpg and http://fw.bushytails.net/bentleadscrew02.jpg is the project. ("before" pictures)
[21:51:49] <Bushman> what are the default units in tool table and how do i change them?
[21:52:00] <Jymmm> OUch, I don't think viagra would help with that. and only temporary no longer than 4 hours
[21:52:22] <Jymmm> furrywolf: wrench left on teh shaft then hit on?
[21:52:26] <PetefromTn_> LOL well if you screwed up like I did and made your machine native metric then the units are metric...so far I have not figured out if you CAN change them.
[21:53:04] <Jymmm> furrywolf: did you get it that way?
[21:53:32] <furrywolf> jymm: the shaft is a bit large for that. I'm straightening it hot.
[21:53:32] <furrywolf> yes
[21:53:53] <Jymmm> furrywolf: you have a piece of glass or granite tile by chance?
[21:53:53] <furrywolf> the machine either, from what I could make out from his story and the damage on it, got hit with a forklift and/or fell on its side.
[21:54:02] <Jymmm> ah
[21:54:04] <furrywolf> no. I have a good eye and a straightedge. :P
[21:54:26] <Jymmm> fuck the straight edge.... check it the same way you do a pool cue ctick
[21:54:37] <furrywolf> since it has a timing pulley on the end with a rubber belt, even if I'm a couple thous off, it'll work just fine...
[21:56:05] <Jymmm> furrywolf: Well, fair enough. But I always find things will "creep out of the woodwork" after it's installed on "good enough"
[21:56:24] <Bushman> PetefromTn_: you mean it's in inches?
[21:56:29] <Bushman> damn it
[21:56:39] <Bushman> i'm not comfortable with this system ;/
[21:56:56] <furrywolf> I've only played pool a couple of times, and don't know how to test a pool stick. I'm mostly just eyeballing it, and spinning it around while looking for wobble. once it's very close, I can put it back in the machine and run a dial indicator on it if I really want it perfect...
[21:57:31] <Bushman> PetefromTn_: but the setting must be somewhere
[21:57:54] <Bushman> after all it's read from machine config, isn't it?
[21:58:13] <Jymmm> furrywolf: Ah... Place the tip on a known flat surface, then while looking down the shaft, rotate it while it's touching the table. Any bow/flex in the shaft will be predominate 360deg around.
[21:58:46] <Jymmm> furrywolf: You dont have to be upclose to it at all
[21:59:49] <furrywolf> I have a pretty good eye for straightness... I can get within a couple thous easily.
[22:00:17] <furrywolf> for better, I can put it back in the machine, and use a dial indicator to measure the runout at a bunch of spots, and find the exact high spot and angle...
[22:00:24] <Jymmm> I've seen poolcues like this --------------/\---\/--- =)
[22:00:34] <PetefromTn_> Bushman No I WISH it was inches... my machine shows metric tool table numbers
[22:01:23] <Bushman> PetefromTn_: i DO understand that our situation is the same but different in the way we need THE OTHER system
[22:01:25] <furrywolf> my machine reads inches on x and y and mm on z. stop bitching.
[22:01:26] <PetefromTn_> I am in US and I set my machine up with metric native units because we thought it would be easier since it had metric screws and someone else has the same machine so we could use his config information to help us.
[22:02:19] <PetefromTn_> that was not the best idea as it turns out as we were unaware you could not select metric/inch for the tool table settings..
[22:03:42] * furrywolf pokes pcw
[22:04:28] <furrywolf> I have no idea why my machine is built this way, other than yay, china. the x and y dials, and the scale on the y axis, are in inches. the z dial reads mm.
[22:05:22] <malcom2073> It's really like they don't even try
[22:06:37] <furrywolf> also, in an unrelated issue, UPS has once again managed to lose my packages... TWO OF THEM. from different places. one was last seen on the 2nd, the other has a destination scan in another state, with no updates since.
[22:06:52] <furrywolf> I really need to stick to my policy of never, ever ordering from any store that will only ship ups.
[22:07:28] <furrywolf> EVERY SINGLE thing I ever get shipped ups is either late, lost, or damaged. without fail. every fucking time.
[22:07:47] <furrywolf> and costs double what USPS would have charged to get it here on time, in half the time, in one piece.
[22:10:49] <unfy> are you in an odd place or something ?
[22:11:02] <furrywolf> northern california
[22:11:12] <furrywolf> which may be considered odd, yes. :P
[22:12:42] <Bushman> PetefromTn_: maybe we should post a feature request for tool table units?
[22:13:37] <unfy> also, spent the weekend soldering ~250 through hole parts. a no name chinese p.o.s. 937d did fine. (a haako clone / rip off)
[22:14:17] <unfy> furry: and the address you use is the one the post office address checker thing suggests ?
[22:14:32] <Bushman> anyway, i've manually modifed the simulator ini file and now have metric tools
[22:16:10] <PetefromTn_> woah what? You changed the tool table units?
[22:16:44] <furrywolf> for soldering through-hole, I've yet to find anything that beats a good ol' 100/140W weller pistol-grip gun. :)
[22:17:01] <furrywolf> I have a temperature regulated digital soldering station... the weller wins.
[22:17:21] <PetefromTn_> or just changed the native units...
[22:18:11] <unfy> this thing did wonderfully set at 375c
[22:18:22] <unfy> and i /hate/ weller stuff
[22:18:35] <furrywolf> unfy: the post office suggests spelling the street name slightly differently (an e where the street name, and sign on the street, has an o), but I've tried both ways, and ups still loses, delays, or damages everything.
[22:18:37] <Tom_itx> PetefromTn_, switch it back to inch then and adjust your screw ratio
[22:18:42] <furrywolf> neither usps nor fedex ever does.
[22:18:50] <unfy> damn ._.
[22:19:11] <unfy> well, learn your lesson! don't do ups no more :D
[22:20:03] <furrywolf> unfy: rather than trying to regulate the tip temperature, I prefer to heat the joint up as quickly as possible. as long as you're melting solder onto the joint, the temperature will regulate itself. so unless you're really slow and dawdle and just leave the tip on a joint you're not actively soldering, regulation isn't useful...
[22:20:11] <furrywolf> unfy: one of them said it was going to ship USPS!
[22:20:24] <unfy> granted, i was mostly only soldering perfboard, so there wasn't a whole bunch of heat sinking going on... so i dunno how the thing performs in the way of thermal capacitance
[22:20:40] <furrywolf> the faster you heat the joint up, the less heat soaks into the component
[22:20:57] <PetefromTn_> Tom_itx Yeah I know that is what I NEED to do but I have been running the damn thing a LOT lately so have not had time to take it down and mess with it.
[22:21:52] <PetefromTn_> AND I am not entirely sure how to do it was actually thinking of maybe seeing if I could setup a Google hangout video chat with someone and see if they can walk me thru how to make an alternate configuration for the machine so I can test stuff..
[22:22:29] <unfy> furry: i use tip temp as just a way to guarunteeing a little bit of wiggle room
[22:22:39] <PetefromTn_> a couple days back PCW had ideas about how to change and what to change but I need to get to trying those things.
[22:23:39] <furrywolf> unfy: I solder quick. :)
[22:24:09] <PetefromTn_> Right now I am programming a bunch of little aluminum 3/4 inch by 5.75" standoffs to be drilled, champfered, rigid tapped and faced on the Cinci in a vertical 5C fixture.
[22:25:38] <Bushman> PetefromTn_: no, i just changed everything back to metric. didn't found any indication for tool table units
[22:25:47] <Bushman> but it would be cool if there was an option
[22:26:02] <unfy> quick is proper technique ... but sometimes things are what they are heh
[22:26:21] <Bushman> cause for example i have both, metric and imperial tool sizes
[22:27:03] <PetefromTn_> Bushman I hear you, sure would be nice if you could just change a setting and viola your tool table is showing inch or metric or whatever you need it to.
[22:27:23] <Bushman> PetefromTn_: there should be an option for selecting it. or atleast a gui that lets you input metric/imperial that converts it to machine units on commit
[22:29:08] <Bushman> from computation point of view the conversion is really simple 1:2.54 IIRC but for a human that's not used to it... well you need a calculator or a piece of paper ;/
[22:29:25] * furrywolf curls up and yawns
[22:29:26] <PetefromTn_> sure it is simple but like you said PIA
[22:30:28] <Bushman> is there a feature request somewhere ?
[22:30:38] <Bushman> where we could post it?
[22:31:36] <Bushman> on unrelated note, i've finally managed to output a working code from DXF2GCODE tool
[22:31:48] <Bushman> http://bushman.pl/misc/screenshots/dxf2gcode_test.png
[22:31:59] <Bushman> still don't know what i did
[22:32:01] <furrywolf> do I need to bother fusing the secondary side of my transformer, or is a primary side fuse adequate?
[22:32:11] <Bushman> but it works and does not spit errors on load
[22:32:26] <PetefromTn_> congrats man
[22:32:51] <Bushman> furrywolf: i'd fuse the secondary
[22:33:04] <Bushman> furrywolf: the primary usually has a termal fuse anyway
[22:33:06] <furrywolf> also, on that part of the circuit, should the e-stop kill the actual power to the stepper drivers, or just the step/dir signals?
[22:33:29] <Bushman> what's the circuit?
[22:34:02] <furrywolf> a simple unregulated power supply for my stepper drivers. 40vac 625va transformer, bridge rectifier, 37,000uf cap.
[22:34:09] <Bushman> also i think it's a bad idea to cut power. they should enforce the stop i think
[22:35:24] <Bushman> make the stepper to stop instantly and not risk (in extreme cases) some flywheel effect
[22:35:28] <furrywolf> and, also related, is a SSR sufficient for the spindle e-stop, or should I toss a mechanical contactor in there? I've never had an ssr fail, and it seems unlikely one would do so at the exact time you're trying to e-stop it...
[22:36:10] <Bushman> i think it's up to you
[22:36:31] <Bushman> it's as safe as safe you feel around it :P
[22:37:09] <furrywolf> well, it's only 3/4hp, with a foot of travel or so in any direction... so it's a bit safer than most machines already...
[22:37:23] <Bushman> on somewhat related note: I WANT ONE!!! http://gosublogger.com/wp-content/uploads/2009/02/usb-panic-button.jpg
[22:37:45] <Bushman> furrywolf: heh, i think you're fine with ssr
[22:37:48] <furrywolf> lol
[22:37:58] <furrywolf> one of my toughbooks has a panic button
[22:38:13] <furrywolf> the f11 key is backlit red and surrounded by a plastic shield
[22:38:21] <Bushman> lol
[22:38:56] <furrywolf> I looked it up when I got it... apparantly that means it was a police issue, with their software that uses the f11 key to initiate a silent "send immediate backup to my location" call.
[22:39:13] <Bushman> oh
[22:40:22] <Bushman> on unrelated note: none of you have noticed what my SIM machine's name is ;>
[22:40:49] * furrywolf has no idea what it is, or where to find it, to be able to notice it.
[22:40:58] <norias> hello
[22:40:59] * Tom_itx is not sure he cares
[22:41:13] <Bushman> furrywolf: on the screenshot
[22:41:26] <Bushman> Tom_itx: fair enough
[22:41:41] <furrywolf> pink dildo? lol
[22:42:11] <Bushman> :D
[22:42:21] * Bushman is being silly
[22:42:26] * furrywolf has a couple! a vixen creations raquel (although it's more a rose), a tantus rippled one, and a je joue uma...
[22:42:26] * Tom_itx is even more sure now
[22:43:49] <Bushman> what are the options for auto-homing?
[22:44:02] <furrywolf> oh, and one that came with a harness I bought a long time ago... no clue what the brand is anymore.
[22:44:26] <Bushman> harness? you mean strap-on?
[22:44:30] <Bushman> :P
[22:44:50] <furrywolf> yes
[22:45:12] <Bushman> i have not investigated homing cause i didn't install switches yet...
[22:45:25] <Bushman> but is there a way to auto home?
[22:45:30] <Bushman> and how does that work?
[22:45:52] <Bushman> how many switches minimum do i need to do that?
[22:46:11] <furrywolf> I have several harnesses... come to think of it, one of my Spare Parts Joque harnesses is pink... but that's not a dildo.
[22:46:23] <furrywolf> if you switches are at the very end of the axis, you need one per axis.
[22:46:33] <furrywolf> using one at each end and having limit switches too is standard, however.
[22:47:06] <norias> so... maybe silly question...
[22:47:23] <norias> but can I use linuxcnc to drive something non-stepper
[22:47:29] <furrywolf> yes
[22:47:34] <norias> specifically... brushed dc motors
[22:47:40] <furrywolf> better known as servos.
[22:47:44] <norias> i.e. the controller on my cnc mill died
[22:48:16] <Bushman> you can use DC motors with feedback (encoders, etc)
[22:48:47] <furrywolf> you'll need enough IO pins for the encoders, so a mesa board, or multiple parallel ports. or drivers that just take step/direction and close the loop internally, of course.
[22:48:52] <Bushman> furrywolf: what the machine does then?
[22:49:08] <norias> drivers seem good
[22:49:15] <norias> i'll look to see what a mesa board is
[22:49:29] <furrywolf> I've never actually set up servos, but I do know they're quite well supported with linuxcnc.
[22:49:31] <Bushman> norias: I/O board
[22:49:37] <norias> fpga based?
[22:49:38] * furrywolf can't afford anything large enough to use them
[22:49:41] <furrywolf> yes
[22:49:47] <norias> ahh, good deal
[22:49:59] <norias> so i/o through paralell port to fpga
[22:50:11] <norias> to motor driver / amplifier
[22:50:22] <furrywolf> or pci card, or ethernet (beta, not well-tested yet).
[22:50:42] <norias> oh, is the mesa deal
[22:50:50] <norias> a generic i/o card?
[22:51:00] <Bushman> heh, yea
[22:51:17] <norias> so, i program the fpga?
[22:52:04] <Bushman> i'm not sure that's required
[22:52:12] <norias> hmm, ok
[22:52:28] <Rab> I believe Mesa supply the firmware as well: http://store.mesanet.com/index.php?route=product/product&product_id=163
[22:52:42] <unfy> here at work, we inherited 50-100 or something GPIO cards. i don't recally if they have any logical inputs, but they do have like 16 or 32 solid state relay outputs.
[22:52:46] <furrywolf> pcw is the mesa expert
[22:53:11] <norias> well
[22:53:17] <norias> this should get interesting
[22:53:41] <Rab> Looks like there are a few firmware options.
[22:53:56] <Rab> http://www.linuxcnc.org/docs/html/drivers/hostmot2.html
[22:53:56] <Bushman> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Editing_MESA_Bitfiles
[22:55:03] <norias> yeah, i just flipped through the "Getting Started"
[22:56:48] <norias> incidentally...
[22:56:50] <Bushman> norias: are your drivers internally closed loop?
[22:57:00] <norias> does linuxcnc have a good mdi /
[22:57:12] <norias> there is some amount of closed loop in the drivers
[22:57:13] <Bushman> define good
[22:57:21] <norias> from what i can tell
[22:57:33] <norias> it takes a tach input
[22:57:36] <Bushman> so the driver input is analog or digita?
[22:57:42] <norias> yeah...
[22:57:49] <norias> i'm going to say analog
[22:57:58] <Bushman> oh, ok.
[22:58:09] <norias> i'm a machinist with a former life in programming
[22:58:20] <Bushman> the MDI is just an input field where you type gcode snippets
[22:58:21] <norias> so i'm ok with the linux part
[22:58:25] <norias> and the machining part
[22:58:39] <norias> the electronics is where i'm getting quickly up to speed
[22:59:02] <norias> hmmm. well, maybe when i get this thing going well
[22:59:08] <norias> i'll write a more useful MDI
[22:59:09] <Bushman> but you have the recently used commands on hand, just need to cursor up to the one you need or double click it
[23:00:04] <Bushman> what do you need it to do in particular?
[23:00:19] <Bushman> just curious what else could there be.
[23:00:32] <norias> the MDI on the milltronics controllers is awesome
[23:00:40] <norias> basically... if it's something dumb and simple
[23:00:44] <norias> you write no g-code
[23:01:04] <norias> i.e. it has a pocket routine you get to through a menu
[23:01:13] <Bushman> oh
[23:01:14] <norias> tell it how big the pocket is
[23:01:17] <norias> where it is
[23:01:17] <Bushman> like this
[23:01:26] <norias> the corner radius, etc
[23:01:28] <Bushman> heh, that would be cool
[23:01:29] <norias> and it goes
[23:01:36] <norias> and...
[23:01:48] <norias> there's an area where you can string together mdi commands
[23:01:50] <norias> in to a program
[23:02:10] <norias> we do all prototyping, so it was super useful
[23:02:13] <furrywolf> bbl, wolfy bedtime
[23:02:21] <norias> you'd do something quick to get it out the door
[23:02:24] <Bushman> if you ever write something like this for linuxcnc, you've got a six-pack of beer from me :D
[23:02:28] <norias> if it came back
[23:02:33] <norias> you could run it again, easil
[23:02:34] <norias> y
[23:02:43] <norias> and if it became more of a production thing...
[23:02:49] <norias> well, re-write in g-code
[23:03:07] <norias> yeah, who knows, i might
[23:03:15] <norias> step one... make the machine work again
[23:03:32] <Bushman> i sometimes need to cut few rectangles and circles... that wold be super-usefull
[23:03:34] <unfy> a noble goal :D
[23:04:08] <norias> i've kinda been itching to do this
[23:04:15] <norias> since i use these machines for a living
[23:04:22] <norias> there are things i like and don't like about them
[23:04:31] <norias> i just didn't want to do it under pressure like this
[23:04:39] <Bushman> oh
[23:04:51] <Bushman> yea, that's usually a PIA
[23:04:58] <norias> like, i like the MDI from the milltronics
[23:05:05] <norias> and, something similar, in a way
[23:05:08] <norias> is...
[23:05:13] <norias> mazatrol
[23:05:20] <Bushman> i hate to re-install my OS and put it aside again and again...
[23:05:26] <norias> interesting language alternative to gcode
[23:05:28] <Bushman> and usually have to do it when something breaks :D
[23:05:48] <norias> nist has some stuff going on with next-gen gcode replacement
[23:05:52] <norias> that i'd love to mess with
[23:06:14] <norias> but a lot of cnc controllers are just a pain in the ass
[23:06:27] <norias> not having conditionals and loops
[23:06:34] <norias> makes me want to murder the people at haas
[23:06:58] <Bushman> hehe
[23:07:09] <Bushman> that's why i love linuxcnc
[23:07:28] <norias> it sounds fun
[23:07:35] <norias> i've been thinking about making a controller
[23:07:39] <Bushman> what i thought being a tape reader became a programming language
[23:07:45] <norias> but, as i said... not an ideal situation
[23:08:15] <norias> oh well, that's life
[23:08:21] <Bushman> i'm inexperienced machinist and my only job where i used to work on CNC was lather... older than me
[23:08:57] <norias> it'll be good for me
[23:09:05] <norias> every difficult experience if more learning
[23:09:07] <Bushman> there was punched tape reader retrofited with digital keyboard and memory but the MDI was still knobs and buttons
[23:09:10] <norias> nice
[23:09:16] <zeeshan|2> norias: you have dc servos w/ tachometers?
[23:09:34] <norias> i'm pretty sure they have tach
[23:09:46] <Bushman> now i'm playing around with my home-made 3-axis CNC mill
[23:09:47] <norias> and rotary encoder + limit switches
[23:09:57] <zeeshan|2> cool
[23:09:59] <zeeshan|2> what drive?
[23:10:07] <norias> hmm... hang on...
[23:10:08] <Bushman> it's quite small, 500x500mm and very ghetto XD
[23:10:16] <norias> glentek ga370
[23:10:26] <norias> if that helps
[23:10:30] <Bushman> http://i.imgur.com/pEEYxmq.jpg
[23:10:36] <norias> i printed the manual for the drives
[23:10:48] <norias> oh, gantry
[23:11:00] <norias> hmm. gantry would not have been my first choice
[23:11:08] <norias> but works for space-constrained applications
[23:11:09] <zeeshan|2> yea you must have tachometers
[23:11:21] <norias> so, zeeshan
[23:11:25] <norias> sounds like you know
[23:11:28] <Bushman> no, the Y is just a board on drawer slides
[23:11:32] <norias> the motor itself has 4 wires
[23:11:36] <Bushman> the "Gate" is stationary
[23:11:39] <norias> i assume two are drive and two are tach
[23:11:46] <norias> different gages of wire
[23:11:51] <norias> does that sound right?
[23:11:57] <zeeshan|2> not for an industrial machine
[23:12:03] <zeeshan|2> tachometer should have 3 wires
[23:12:06] <zeeshan|2> 2 signal
[23:12:07] <zeeshan|2> 1 shield
[23:12:13] <norias> hmm.
[23:12:17] <norias> ok
[23:12:17] <zeeshan|2> then +/- for motor
[23:12:23] <zeeshan|2> unless you have no shield?
[23:12:26] <zeeshan|2> which is very weird :)
[23:12:29] <norias> i'll have to look again tomorrow
[23:12:45] <Bushman> disection of corpses!
[23:12:46] <zeeshan|2> but you must have tachometer for that little #of wires
[23:12:48] <Bushman> FUN!
[23:12:50] <norias> would you really need a good tach if it also has a rotary encoder?
[23:12:50] <Bushman> :D
[23:13:05] <zeeshan|2> that i dont know
[23:13:08] <zeeshan|2> mine uses tachometer
[23:13:10] <zeeshan|2> w/ absolute encoder
[23:13:11] <PetefromTn_> Here's a stupid question if you are rigid tapping a left hand thread using G33.1 how is this accomplished? If you had G84 or G74 one or the other is the reverse...
[23:14:39] <zeeshan|2> PetefromTn_: maybe just turn the spindle the opposite way?
[23:14:41] <zeeshan|2> before g33.1
[23:15:11] <norias> sounds right to me
[23:15:31] <norias> it's just syncing z mooves to spindle revolutions
[23:16:04] <PetefromTn_> yeah I am trying to get my Cam to cooperate and output the correct programming..
[23:16:31] <norias> hah
[23:16:44] <norias> write that part by hand
[23:16:59] <norias> faster than getting angry cam to cooperate
[23:17:10] <norias> imho
[23:17:24] <PetefromTn_> no thanks...
[23:17:54] <norias> do everything else with cam
[23:17:58] <norias> and add in the rigid tapping
[23:18:08] <zeeshan|2> i tried to setup g33.1 w/ cam
[23:18:11] <norias> i rarely trust cam to get tapping right, anyway
[23:18:34] <zeeshan|2> i gave up
[23:18:38] <zeeshan|2> ended up just using g33 :P
[23:19:13] <zeeshan|2> whoops i misxed that up. not g33.1 , g76
[23:22:33] <PetefromTn_> sure would be easier if linuxCNC used G84/74
[23:22:48] <norias> hmmm...
[23:22:49] <zeeshan|2> PetefromTn_: what cam are you using
[23:22:57] <norias> i don't think 74/84 sync the spindle
[23:23:01] <PetefromTn_> CamBam
[23:23:09] <norias> because i think those are for floating tapping heads
[23:24:41] <norias> ymmv
[23:27:28] <PetefromTn_> well it was on all the HAAS machines I have run. Rigid tap G84/74 http://diy.haascnc.com/g-codes-mills
[23:28:08] <norias> fair
[23:28:29] <norias> and f haas anyway
[23:28:42] * norias grumbles about conditionals and loops.
[23:29:38] <PetefromTn_> sorry you feel that way. I found them to be quite nice and realiable machines.
[23:29:59] <norias> yeah, they are actually pretty nice
[23:30:14] <norias> i like everything but the control interface :)
[23:30:34] <PetefromTn_> thats actually what I like about them most
[23:31:05] <norias> huh.
[23:31:19] <norias> i hear that a bit.
[23:31:45] <norias> i think milltronics crushes them from a control standpoint
[23:31:54] <zeeshan|2> f that
[23:31:58] <zeeshan|2> fanuc and simnuerik!
[23:32:06] <norias> ha1
[23:32:09] <norias> anilam!
[23:32:14] <norias> that's where i started
[23:32:16] <PetefromTn_> haas is basically a fanuc control
[23:32:25] <norias> actually, anilam sucked.
[23:32:39] <zeeshan|2> actually im gonna say this
[23:32:43] <zeeshan|2> Screw all industrial control
[23:32:46] <zeeshan|2> and their propietary bs
[23:32:54] <zeeshan|2> LINUXCNC + MESA FTW
[23:33:00] <PetefromTn_> fer sure..
[23:33:16] <zeeshan|2> fanuc is the worst i would think
[23:33:17] <PetefromTn_> mine ran beautifully all Freakin' day long making chips today again...
[23:33:19] <zeeshan|2> all their shit is top scret
[23:33:21] <norias> heidenhein is pretty bad
[23:33:26] <zeeshan|2> norias: oh trust me
[23:33:27] <zeeshan|2> i know!
[23:33:39] <zeeshan|2> i just got rid of a heidenhain control
[23:33:43] <zeeshan|2> tnc155
[23:33:49] <norias> i ran some 3,4 and 5 axis machines on those
[23:33:57] <norias> never really got the hang of that language
[23:33:59] <zeeshan|2> im only keeping the scales from heidenhain
[23:34:05] <PetefromTn_> I just wish LinuxCNC used more industry standard G-codes like G84/74 etc..and a few others.
[23:34:07] <norias> i hear those scales are pretty good
[23:34:21] <zeeshan|2> PetefromTn_: honestly linuxcnc has it all pretty much
[23:34:34] <zeeshan|2> if cam post processors worked for linuxcnc out of the box, that would be sweet
[23:34:35] <PetefromTn_> how ya figure
[23:34:42] <zeeshan|2> you dont need that extra stuff man
[23:34:47] <zeeshan|2> all those canned cycles etc
[23:34:53] <PetefromTn_> BS
[23:34:54] <zeeshan|2> if youre doing it by hand, yea it makes sense
[23:34:58] <zeeshan|2> but if you're using cam
[23:35:00] <zeeshan|2> who cares?
[23:35:09] <norias> i'm 50/50 some days with cam
[23:35:15] <zeeshan|2> what diff does it make to use say a g33 vs g76
[23:35:19] <PetefromTn_> I AM using cam and I would LOVE to use G84 heh
[23:35:20] <zeeshan|2> g76 is one line
[23:35:23] <zeeshan|2> g33 is like 20
[23:35:32] <PetefromTn_> ?
[23:35:48] <PetefromTn_> and the K factor is proving difficult
[23:36:09] <PetefromTn_> G33.1 Z-0.750 K0.05 (rigid tap a 20 TPI thread 0.750 deep)
[23:36:46] <zeeshan|2> what do you mean its difficult?
[23:36:47] <t12_> hi all
[23:36:52] <t12_> servo tuning question
[23:36:56] <norias> yeah, i missed the hard part there
[23:37:10] <PetefromTn_> I mean I have not been able to get my CAM to output it
[23:37:17] <t12_> i have a servo driving a centrifuge
[23:37:21] <zeeshan|2> that likely isn't a variable
[23:37:27] <norias> oh, so it's a CAM problem
[23:37:28] <PetefromTn_> when I have rigid tapped I had to hand code it which is a PIA
[23:37:28] <zeeshan|2> you might need to write a new variable
[23:37:36] <t12_> tuning it is .... weird
[23:37:53] <zeeshan|2> actually u dont need a new variable
[23:37:58] <t12_> are there any established procedures for servo tuning when you know you're going to have way more mass tied up in the work
[23:37:59] <zeeshan|2> you just need to do 1/tpi
[23:38:02] <zeeshan|2> need to find tpi variable
[23:38:02] <t12_> than in the drive chain?
[23:38:14] <PetefromTn_> trying to remember how you set it up in mastercam for a rigid tap....been awhile
[23:38:27] <zeeshan|2> i dont know if the post processor is the same
[23:38:31] <zeeshan|2> but it uses some random langauge
[23:38:34] <zeeshan|2> to spit out g-code
[23:38:46] <PetefromTn_> you have mastercam right?
[23:38:49] <zeeshan|2> yea
[23:38:59] <zeeshan|2> i needed to find out when i write 20tpi in cam gui
[23:39:06] <PetefromTn_> when you program the tap in the software what did it ask for?
[23:39:08] <zeeshan|2> what variable in the cam post porcessor relates to that
[23:39:36] <PetefromTn_> trying to setup CAMBAM to work similarly
[23:39:40] <zeeshan|2> lead, included angle, thread angle
[23:39:48] <zeeshan|2> thread depth, major diameter, minor diameter
[23:39:56] <zeeshan|2> but you clicked "Select from table"
[23:39:57] <PetefromTn_> on mill?
[23:40:11] <zeeshan|2> and chose the thread type and it filled all of it for you
[23:40:14] <zeeshan|2> no for lathe
[23:40:19] <zeeshan|2> for rigid tapping you just need to find out tpi
[23:40:26] <zeeshan|2> masteram has a table for that
[23:40:42] <PetefromTn_> yeah I know lathe is different because you are single point threading or whatever I am talking about a simple rigid tap
[23:40:51] <PetefromTn_> in mill mode
[23:41:17] <zeeshan|2> i 'd think you'd only need depth of thread
[23:41:21] <zeeshan|2> and tpi
[23:41:41] <PetefromTn_> thats what I thought but I don't remember
[23:41:47] <zeeshan|2> or if you dont wanna use g33.1
[23:41:54] <zeeshan|2> actually nm
[23:41:57] <zeeshan|2> you could use eitehr g33 or g33.1
[23:42:12] <PetefromTn_> in mastercam mill?
[23:42:12] <zeeshan|2> with g33 you'll need to do a g01 at the end of the trhead
[23:42:14] <PetefromTn_> how
[23:42:58] <zeeshan|2> fuck sorry man
[23:43:00] <zeeshan|2> i keep thinking lathe
[23:43:01] <zeeshan|2> LOL
[23:43:23] <zeeshan|2> if you wanted to use g33, itd be a bit more involved
[23:43:49] <zeeshan|2> you'd do like m3 (run spindle clockwise)
[23:43:57] <PetefromTn_> LOL When I get my CNC lathe up and running we'll talk hehe
[23:44:08] <zeeshan|2> g33 k0.05
[23:44:13] <zeeshan|2> g01 distance of thread
[23:44:32] <zeeshan|2> at end of thread you'd call m4
[23:44:40] <zeeshan|2> and g01 back up the thread
[23:44:51] <zeeshan|2> but im thinkng, that might not work as good, because g33.1 prolly has a dwell somewhere
[23:44:56] <zeeshan|2> to slow down towards the end of the thread
[23:45:04] <PetefromTn_> G33.1 takes care of all of that
[23:45:07] <zeeshan|2> yea
[23:45:19] <PetefromTn_> just need the depth and feed per rev.
[23:45:32] <PetefromTn_> it is the feed per rev I am having trouble outputting here.
[23:46:18] <zeeshan|2> okay you need to figure figure out if its a left hand or right hand thread
[23:46:26] <zeeshan|2> so the first g-code it outputs is the correct spindle direction
[23:46:45] <zeeshan|2> then find the post procesor line that is outputting g74 for example
[23:47:27] <zeeshan|2> change it to g33.1? :P
[23:47:30] <PetefromTn_> well the rotation is setup in the previous line
[23:47:34] <Bushman> FML. "Arc move in concave corner cannot be reached by the tool without gouging"
[23:47:38] <PetefromTn_> that is already done
[23:48:20] <PetefromTn_> already got it to output the G33.1 but it wants to give me an F instead of the K and it is actual feedrate which won't work
[23:48:26] <Bushman> so in other words tool compensation can't compensate for two arcs meeting at small angle ;/
[23:49:03] <zeeshan|2> what is the feedrate its trying to output
[23:49:18] <zeeshan|2> when you do 20 tpi
[23:49:49] <PetefromTn_> G99 G33.1 Z-.35 R.1 F44.57 that is what I am getting for a 3/8-16 to -.35 deep right now
[23:50:26] <Bushman> i thought that AXIS is ploting a tool path that goes along the line and just ignores places it can't reach... it does that for squares, why can't it do the same for two arcs meeting in a concave corner?
[23:50:30] <zeeshan|2> wonder where the hell its getting 44.57
[23:50:30] <zeeshan|2> haha
[23:50:43] <PetefromTn_> feedrate
[23:50:56] <zeeshan|2> 44.57 ipm
[23:51:10] <zeeshan|2> can you find out the variable that is storing 16?
[23:51:49] <PetefromTn_> G99 G33.1 Z-.35 R.1 F12.5
[23:52:00] <PetefromTn_> oops sorry I fat fingered the spindle speed
[23:52:08] <PetefromTn_> that second one is at 200 RPM
[23:52:33] <zeeshan|2> whats R
[23:52:42] <PetefromTn_> retract plane I think
[23:52:53] <zeeshan|2> theres gotta be something in the post prcessoer
[23:52:56] <zeeshan|2> that has tpi in it
[23:53:02] <PetefromTn_> don't want that in there either I think..
[23:53:07] <zeeshan|2> yea dont want that :P
[23:53:09] <zeeshan|2> just delete it
[23:53:21] <zeeshan|2> or you might need it
[23:53:29] <zeeshan|2> so that it knows how high to bring the tap after its done
[23:53:41] <PetefromTn_> well what I am TRYING to get to is to be able to just post code without fucking with it afterwards....
[23:53:53] <zeeshan|2> its like this man
[23:53:58] <zeeshan|2> it takes forever to fuck with this stupid crap
[23:54:04] <zeeshan|2> just to output a simple g-code
[23:54:09] <PetefromTn_> http://linuxcnc.org/docs/html/gcode/gcode.html#sec:G33_1-Rigid-Tapping
[23:54:10] <zeeshan|2> thats why i gave up on nx
[23:54:13] <zeeshan|2> its the worst.
[23:54:38] <zeeshan|2> and mastercam's post processor is so ugh
[23:54:44] <zeeshan|2> that it combines lathe, milling, 5 axis,
[23:54:47] <zeeshan|2> lathe+milling
[23:54:49] <zeeshan|2> all ine one.
[23:54:51] <PetefromTn_> well actually what takes FOREVER is continually having to hand code shit because your CAM program doesn't talk nice to your LinuxCNC machine
[23:54:54] <zeeshan|2> so finding something is a nightmare
[23:55:12] <zeeshan|2> PetefromTn_: you know whats funny?
[23:55:22] <zeeshan|2> i had this retarded F that woudn't change to a P i believe
[23:55:27] <zeeshan|2> whatever i was doing with g76
[23:55:31] <Bushman> PetefromTn_: i'm having this exact issue just now
[23:55:39] <zeeshan|2> i ended up passing the file through a bash script
[23:55:41] <zeeshan|2> in linux..
[23:55:51] <zeeshan|2> to replace the damn F with a P
[23:55:58] <zeeshan|2> whenever it say an occurence of g76
[23:56:02] <zeeshan|2> i still havent figured it out
[23:56:06] <zeeshan|2> how to spit it properly.
[23:56:10] <PetefromTn_> this would be simpler if linuxCNC just took standard G84/74 codes
[23:56:13] <Bushman> "Arc move in concave corner cannot be reached by the tool without gouging" and i have no idea how to walk around it
[23:56:24] <zeeshan|2> PetefromTn_: i wouldn't blame linuxcnc
[23:56:34] <zeeshan|2> mastercam makes thousands of dollars
[23:56:37] <PetefromTn_> why?
[23:56:41] <zeeshan|2> to write a special post processor for a specific machine
[23:56:45] <zeeshan|2> because all controls are dif man
[23:57:00] <PetefromTn_> sure but those are pretty well standard codes in industry
[23:57:15] <zeeshan|2> i bet they dont exist in a sinumerik control
[23:57:33] <PetefromTn_> never heard of a sinumerik control really
[23:57:39] <Bushman> that seriously limits my design options. i can't make two arcs meet at the same point :(
[23:57:40] <zeeshan|2> its a siemens control
[23:57:43] <zeeshan|2> its on a lot of german machines
[23:57:49] <zeeshan|2> am using G74 for Auto Referencing in Linear axis, When I Commend G74
[23:57:49] <zeeshan|2> lol
[23:57:54] <zeeshan|2> its something else in sinumerik.
[23:58:43] <PetefromTn_> Bushman sounds like the tool won't fit in the corner you drew IE the corner radius is smaller then the tool radius
[23:59:40] <zeeshan|2> g84 looks slightly diff in centriiod control too
[23:59:45] <zeeshan|2> it needs a P (dwell time)
[23:59:48] <zeeshan|2> at bottom of hole?
[23:59:51] <zeeshan|2> or is that the same in haas
