[00:08:54] <r00t4rd3d> I doubt you will find someone who can give you an accurate number. The structural integrity of your machine and how it handles and dissipates force makes it impossible to tell you a number for a DIY machine.
[00:09:51] <LeelooMinai> Hmm... I am not sure why do you talk about "machine"... that's not what I asked.
[00:10:16] <LeelooMinai> I am asking what forces are involved in milling aluminium
[00:10:25] <r00t4rd3d> lol
[00:10:36] <r00t4rd3d> I just told you.
[00:11:16] <r00t4rd3d> I guess its not the answer you want to hear though
[00:11:51] <LeelooMinai> Surely not - since I just need some figure to build the "machine" :p
[00:12:04] <r00t4rd3d> a lot.
[00:12:09] <LeelooMinai> Assume you are cutting aluminium with theoretical super-rigid machine.
[00:12:26] <LeelooMinai> Or even infinitelly rigid.
[00:12:44] <LeelooMinai> At some DIY/slowish speed at home
[00:12:48] <r00t4rd3d> ive seen people cut aluminum with a MDF framed router
[00:13:10] <r00t4rd3d> http://www.microcarve.com/mcMV1.html
[00:13:16] <r00t4rd3d> them things there
[00:13:35] <LeelooMinai> That's great... but I jsut said "assume infinitelly rigid machine" and you are talking about MDF router somehow:p
[00:14:03] <r00t4rd3d> im done.
[00:14:42] <r00t4rd3d> being a cock breath when someone cant give you a answer is a sure fuckface move.
[00:15:25] <LeelooMinai> Well, I guess you don't underrstand my question.
[00:15:36] <r00t4rd3d> well i guess you dont fucking understand engrish.
[00:16:47] <LeelooMinai> I tried to explain what I am asking - but you insist on involving materials the CNC is made from.
[00:17:21] <r00t4rd3d> i just farted
[00:18:11] <LeelooMinai> Right... well... at least you succeded at something in this conversation:)
[00:18:29] <r00t4rd3d> you are really starting to irritate me.
[00:18:53] <LeelooMinai> I thinkk you irritete yourself by not listening and blaming others.
[00:19:02] <r00t4rd3d> stfu
[00:19:44] <LeelooMinai> Lost temper is lost
[00:20:34] <mr_new> good morning
[01:37:30] <archivist> LeelooMinai, the forces can be calculated from cut depth, sharpness of cutter, strength of material and rpm of spindle so the number is not anywhere a constant you can adjust
[01:44:44] <anonimas1> LeelooMinai: there's a calculation like that in the seco book or sandvik i think.
[02:04:48] <archivist> LeelooMinai, are you doing finite element analysis in your design ?
[03:14:36] <Tom_itx> archivist, i think i have somewhere a chip load calculator that translated the ipt into HP or such that may be on the same track as what he is looking for
[03:15:41] <Tom_itx> number of teeth, diameter of tool, depth of cut, material etc
[03:17:37] <archivist> I have the calcs in a Cincinnati milling book too
[03:18:05] <Tom_itx> not one i use often
[03:18:12] <archivist> probably out of date though compared to a modern machine
[03:31:59] <mr_new2> hi
[03:34:17] <mr_new2> anyone an idea how to controll a spindle with 15-60v 1000hz? is it possible to build an inverter myself?
[03:36:38] <archivist> anything is possible, now what is the question
[03:38:56] <mr_new2> how to do that?
[03:39:40] <mr_new2> or why are they so expensive?
[03:42:28] <archivist> is this a bldc motor
[03:43:39] <mr_new2> i think its an asynchron
[03:44:14] <mr_new2> it is a jäger hf spindle
[03:46:53] <gammax> whats themetal spacer that goeson the inside of a cnc's way called?
[03:47:37] <archivist> gib strip
[03:47:48] <gammax> there we go! thanks!
[03:48:00] <gammax> any idea where iI can buy a newone?
[03:48:06] <gammax> I have one that is broke in half
[03:51:41] <archivist> is it a taper one
[03:52:06] <archivist> make one
[03:52:57] <gammax> themill is down at the moment...
[03:53:16] <archivist> file, and scraper
[03:53:35] <gammax> lol possible...
[03:56:28] <archivist> or if desperate take measurements and go to a local machine shop, make me one
[04:20:24] <Loetmichel> mornin'
[04:35:07] <carper64_lb> mornin
[05:41:52] <mr_new2> what a waveform do i need to get a hf spindle running?
[05:57:03] <jthornton> tsunami
[09:13:03] <L84Supper> http://www.cnccookbook.com/CCMillEpoxyFill.htm I like his low budget hockey puck dampening feet
[09:44:31] <r00t4rd3d> http://www.costco.co.uk/view/product/uk_catalog/cos_1,cos_1.2,cos_1.2.4/140490
[09:47:53] <r00t4rd3d> hmm the Crazyflie is available now.
[09:47:54] <r00t4rd3d> http://www.seeedstudio.com/depot/preorder-crazyflie-nano-quadcopter-kit-10dof-with-crazyradio-bccfk02a-p-1365.html?cPath=170_172
[09:50:10] <ReadError> lame
[09:57:24] <Loetmichel> *hmm*... THAT drilling will take a while...
[09:57:25] <Loetmichel> -> http://www.youtube.com/watch?v=NxxhvO6wP08
[09:57:26] <Tecan> (NxxhvO6wP08) "920 x 3,0 mm" by "Loetmichel" is "People" - Length: 0:00:19
[10:07:00] <L84Supper> Loetmichel: making your own perfboard?
[10:08:59] <L84Supper> r00t4rd3d: I'd settle for a durable USB racing wheel, they all wear out in a few months
[10:15:42] <tjb1> lol this guy just said hardinge machines were junk
[10:21:30] <mozmck> tell him I'll take any he has off his hands for free. I won't even charge him to come get them!
[10:22:31] <archivist> send me one or three too
[10:22:55] <tjb1> He wanted me to come interview and I told him the offer from hardinge
[10:23:02] <tjb1> He was like oh they arent out of business yet?
[10:23:40] <archivist> some do rubbish the opposition :)
[10:24:01] <tjb1> He wasnt a machine manufacturer
[10:25:45] <tjb1> Took him like 5 minutes to tell me they couldnt match the offer so I am not wasting my time with a 2.5 hour uncompensated drive
[10:26:15] <jdh> hardinge employee discounts?
[10:26:35] <jdh> guess that still wouldn't make them affordable
[10:26:46] <tjb1> They have a machine they only made 4 of
[10:26:50] <tjb1> and 2 of them are in the plant
[10:27:32] <tjb1> Some lathe that had a mill style tool changer
[10:27:41] <tjb1> live tooling, dual spindles, etc...
[10:37:13] <L84Supper> http://www.gizmag.com/cellulose-nanocrystals-stronger-carbon-fiber-kevlar/23959/ maybe those wooden frame routers aren't such a joke after all, with the right mods
[10:46:30] <Loetmichel> L84Supper: making a shielded case for a netgear NAS
[10:53:39] <WalterN> L84Supper: well, I finally got my laser... and it comes with optics.
[10:53:57] <WalterN> L84Supper: but I'm not sure what kind of optics... it has two lenses
[10:55:52] <L84Supper> WalterN: did you get your laser safety glasses yet?
[10:56:21] <WalterN> no... they shipped on friday... should be here sometime later this week
[10:56:46] <WalterN> dont have a power supply either though... *shrug*
[10:56:56] <L84Supper> hate to see you with the pirate eye patch
[10:57:29] <WalterN> I just unscrewed one of the lenses
[10:57:45] <WalterN> thor labs?
[10:58:07] <WalterN> C220TME
[10:58:09] <L84Supper> http://www.thorlabs.us/
[10:58:13] <WalterN> -B
[10:58:34] <L84Supper> http://www.thorlabs.us/search/thorsearch.cfm?search=C220TME
[10:59:20] <WalterN> that one is the exit lense
[11:00:35] <L84Supper> http://www.thorlabs.us/catalogpages/V21/729.PDF
[11:01:30] <WalterN> the other is...
[11:01:48] <WalterN> A220TM-B
[11:06:23] <WalterN> how much do those cost?
[11:06:37] <L84Supper> it's all in that .pdf
[11:06:49] <L84Supper> for both
[11:06:50] <DJ9DJ> moin
[11:07:24] <WalterN> L84Supper: is that the set of lenses that I want?
[11:12:54] <WalterN> hmm... both look like magnification things...
[11:17:51] <L84Supper> now is the time to put on your tinkering hat, not look into the laser and see how the lenses work
[11:18:15] <L84Supper> try them with a low powered laser pointer
[11:21:35] <WalterN> oh you know what
[11:21:56] <WalterN> L84Supper: it looks like there is supposed to be another fiber optic cable here
[11:22:09] <WalterN> at least, from what it was taken out of
[11:22:20] <WalterN> that would make the most sense
[11:22:30] <cpresser> WalterN: is it a CO2-Laser?
[11:22:51] <cpresser> because: there is no fiber-optic for that wavelength :)
[11:23:04] <L84Supper> fiber coupled IR laser
[11:23:21] <WalterN> cpresser: diode laser
[11:23:24] <L84Supper> he bought the whole assembly on ebay
[11:23:49] <WalterN> yeah, came with a bunch of useful stuff... trying to figure out what that useful stuff does
[11:23:58] <WalterN> (lol)
[11:24:02] <L84Supper> 30W forget the wavelength
[11:24:08] <WalterN> 808nm
[11:24:40] <cpresser> put on some glasses that block IR. it makes you feel save :)
[11:25:29] <WalterN> cpresser: yeah, those are on the way... will be here later this week. still need a power supply though
[11:28:39] <L84Supper> pcw_home: any Mesa FPGA board with some DDR3 on it in the real near future?
[11:28:41] <WalterN> this is kind of shiny
[11:29:04] <L84Supper> pcw_home: and PCIe
[11:29:15] <WalterN> this frame thing I think is made out of a chunk of titanium too
[11:29:17] <cpresser> L84Supper: what do you need DRam for?
[11:29:34] <L84Supper> cpresser: frame buffer
[11:30:47] <cpresser> use a slower resolution and do it in the sram :D
[11:32:01] <L84Supper> heh, can't make the images smaller
[11:34:49] <L84Supper> http://www.xilinx.com/products/boards-and-kits/EK-S6-SP605-G-image.htm
[11:36:56] <Icekiller> hey guys anyone know if pieter from ebay sells tr12x3 with the ends milled or..?
[11:38:49] <WalterN> L84Supper: http://tiwake.com/IMG_0365.JPG
[11:41:56] <pcw_home> Why do you need a frame buffer? seems line a small buffer plus DMA would be fast enough
[11:42:09] <pcw_home> what is you data rate?
[11:43:43] <pcw_home> (For Video OK for a printer I doubt you can outrun even PCI data rate)
[12:16:49] <IchGuckLive> hi all B)
[12:29:51] <largecheesepuff> anyone around?
[12:30:59] <IchGuckLive> yes
[12:30:59] <L84Supper> just ask
[12:31:58] <IchGuckLive> No Q nA
[12:32:12] <largecheesepuff> ok
[12:32:38] <largecheesepuff> I will just post something on the forums.
[12:32:59] <IchGuckLive> special router ?
[12:33:22] <largecheesepuff> no I have been working on gang tooled lathe
[12:33:44] <IchGuckLive> nice
[12:34:15] <IchGuckLive> howmany tools in row
[12:34:25] <largecheesepuff> seems after much research I've answered most of my questions
[12:35:04] <IchGuckLive> B)
[12:36:37] <largecheesepuff> maximum of 8 with parting tool
[12:36:44] <largecheesepuff> 9 without
[12:36:53] <IchGuckLive> good
[12:37:17] <IchGuckLive> ive seen 12 on the Yang SL-12
[12:38:16] <largecheesepuff> I've been struggling a bit with how to handle "tool changes"
[12:38:59] <largecheesepuff> but seems I found most of the information I've been looking for yesterday
[12:39:00] <IchGuckLive> special on workflow of both sides it is difficult
[12:39:18] <IchGuckLive> best to go for a Mcode workflow
[12:39:30] <largecheesepuff> yeah, I'm still fuzzy on that topic
[12:40:18] <IchGuckLive> you can remap your own
[12:41:20] <largecheesepuff> that is what I looking at
[12:41:38] <andypugh> Do you actually need a toolchange with gan=tooling.
[12:42:06] <andypugh> I can imagine that if you have a toochange position programmed in, then just tool offsets would suffice.
[12:43:51] <IchGuckLive> largecheesepuff: have you sen the Jinn SMART-42Y with 48 tools in a gan Block
[12:44:29] <memleak> Hello everyone! I'm trying to compile EMC but it says it cannot find boost::python shared libraries but it is already installed.
[12:44:54] <IchGuckLive> memleak: OS ?
[12:45:07] <memleak> Gentoo.
[12:45:40] <memleak> Where are the boost python libraries in ubuntu?
[12:45:42] <largecheesepuff> IchGuckLive: I have n ot
[12:45:45] <largecheesepuff> not
[12:45:48] <memleak> I'll set up a symlink :D
[12:45:50] <L84Supper> ask in linuxcnc-devel, it's more user and machine talk in here
[12:46:25] <IchGuckLive> memleak: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?EmcOnGentoo
[12:47:57] <IchGuckLive> memleak: it runs only with the given commit not an updatet one
[13:02:20] <largecheesepuff> IchGuckLive: any good links?
[13:02:35] <IchGuckLive> towards
[13:02:50] <IchGuckLive> remap ß
[13:03:05] <largecheesepuff> oh that lathe
[13:03:19] <IchGuckLive> Jinn SMART-42Y
[13:03:33] <IchGuckLive> google pictures
[13:04:14] <IchGuckLive> triangel 3x9 GAN and a chan with toolchanger
[13:04:30] <IchGuckLive> chain
[13:15:13] <IchGuckLive> im off by
[13:31:53] <skunkworks> http://groups.yahoo.com/group/mach1mach2cnc/message/139705
[13:38:55] <PCW> Lovely that they have a closed motion control interface API
[13:39:41] <archivist> that will force the chinese to linuxcnc
[13:40:49] <cradek> the stated purpose is to keep too many (or "new"?) people from making hardware that works with it
[13:41:00] <L84Supper> it will be interesting in the next year to see what the reaction is in China
[13:41:38] <archivist> 15 minutes between restarts, unusable for the free version
[13:44:03] <skunkworks> I don't see this going well..
[13:44:10] * skunkworks hugs linuxcnc again and again
[13:44:39] <PCW> Sounds like IBM and PS2 (everybody must pay a license fee to join our happy happy gang, hey! where are you guys going?)
[13:45:37] <cradek> sounds like they might have written it "the emacs way" (http://technomancy.us/161) which is good for them
[13:46:02] <cradek> PCW: don't you still use microchannel machines!?
[13:46:54] <DaViruz> i threw away my MCA machine less than a year ago
[13:47:42] <PCW> Much smarter than ISA and if they made it open it might have succeeded
[13:47:52] <cradek> that's sure true
[13:48:12] <cradek> although EISA failed over time, too
[13:48:46] <cradek> it was pretty cool - give it the floppies that came with the cards, and it'd work out all the settings
[13:50:47] <DaViruz> i wonder how much problems would have surfaced if it had seen widespread use though..
[13:51:28] <PCW> True of most any interface...
[13:53:34] <skunkworks> vesa local bus?
[13:53:57] * skunkworks remembers his hurcules video card...
[13:54:16] <DJ9DJ> herkules!
[14:00:06] <PCW> They were just down the street from us when we where in Emeryville
[14:39:38] <tjb1> anyone experienced with corel draw?
[14:39:58] <DJ9DJ> Loetmichel is
[14:41:59] <Loetmichel> a bit
[14:42:10] <WalterN> I've used it a couple times... I kind of hate it though
[14:42:19] <WalterN> kind of a lot
[14:43:08] <tjb1> Anyone willing to convert a dxf to an appropriate svg file for ponoko?
[14:46:29] <LeelooMinai> tjb1: Use inkscape, but make sure ut exports in mm not pixels
[14:46:46] <tjb1> I tried inkscape
[14:46:51] <tjb1> I tried illustrator
[14:47:00] <tjb1> Ponoko keeps telling me it is wrong
[14:47:23] <LeelooMinai> tjb1: Did you look into exported svg and verified the main units are in mm?
[14:47:46] <tjb1> Not sure how?
[14:47:50] <LeelooMinai> You can open svg in any text editor
[14:48:08] <tjb1> At one point ponoko was saying too much blue which meant the line was too thick or it had fill or something
[14:48:58] <LeelooMinai> width="744.09448819" height="1052.3622047" <- at the top of file, you want those to have mm appended at the end, otherwise it's pixels
[14:49:21] <LeelooMinai> Hmm...
[14:49:28] <LeelooMinai> What is poniko anyways? :)
[14:49:58] <LeelooMinai> OK, I see - yes, laser cutting
[14:49:58] <tjb1> https://www.ponoko.com/
[14:50:26] <LeelooMinai> So... what I sad about mm, plus, hm, well, maybe make all lines thin in Inkscape?
[14:50:57] <WalterN> tjb1: there are issues with making something in inkscape and opening it with corelldraw... I found just exporting the SVG (in inkscape) to a PS file, and opening the PS file in corell draw to work for me
[14:51:16] <tjb1> I made it in solidworks
[14:52:16] <WalterN> DXF in inkscape is... weird
[14:52:41] <LeelooMinai> well, Inskape is used mostly to go from DXF to SVG...
[14:52:49] <LeelooMinai> I used it as a converter that is
[14:52:58] <LeelooMinai> In my case I had export from SolidEdge
[14:53:17] <WalterN> I was trying to use DXF to open the SVG in corell draw
[14:53:27] <WalterN> did I mention that I hate corell draw?
[14:54:02] <Loetmichel> tjb1: dxf is a problem because corel has a bux in the dxf import: anythin bigger than 254mm will get resized to 254mm
[14:54:23] <WalterN> corel is one giant bug
[14:54:34] <tjb1> https://www.dropbox.com/s/13pedv2syg8lrxb/acrylicbedletteredcentered.dxf
[14:55:28] <Loetmichel> one moment, starting VM
[14:55:56] <Loetmichel> (CD8 wont run under win7)
[14:57:55] <Loetmichel> tjb1: how big it is supposed to be?
[14:58:03] <tjb1> 1 second
[14:58:31] <Loetmichel> corel is telling me 254,0mm by 219.97mm can you correct that?
[14:58:40] <tjb1> The sides are 260.375
[14:58:43] <tjb1> the flat sides
[15:02:36] <andypugh> Sanity check? I just installed a 2.5mm mono jack plug and socket in my machine. As soon as I insert the jack plug there is continuity between every terminal in the socket, and the case, and every terminal in the plug. That's wrong isn't it?
[15:03:04] <Loetmichel> it is ;-)
[15:03:12] <Loetmichel> tjb1: svg output?
[15:03:21] <tjb1> ?
[15:03:25] <cradek> depends what's connected to the plug?
[15:03:28] <Connor> andypugh: Mono in stero jack ?
[15:03:40] <andypugh> They are both labelled "mono"
[15:04:03] <andypugh> Even then it shouldn't short _everything_ ?
[15:04:10] <Connor> does the jack have a make/break switch on it ?
[15:04:36] <DaViruz> andypugh: does it short while you insert? or when it is fully inserted?
[15:04:43] <DaViruz> shorted during insertion is fairly typical
[15:04:46] <Icekiller> anyone here know where in Belgium/Germany i cang et tr12x3 endings milled ?
[15:04:48] <andypugh> I don't know. It has two terninals and the case terminal.
[15:04:59] <andypugh> And it shorts during and after insertion.
[15:05:06] <Loetmichel> tjb1: wht do you want to have as output?
[15:05:11] <tjb1> svg
[15:05:15] <Connor> so, no make break.. Bad jack or plug then..
[15:05:28] <tjb1> Loetmichel: I need the outline and holes to be blue
[15:05:29] <andypugh> Icekiller: Ballscrew ends?
[15:05:38] <tjb1> and the grid and letters to be filled black
[15:05:47] <Loetmichel> tjb1: that wouldnt be a problem
[15:06:04] <Loetmichel> SVG is... corel draw 8 is to old... no svg exporter :-(
[15:06:37] <andypugh> Icekiller: Ah, no, trapezoidal. Are you saying you have the screws, but can't machine the ends?
[15:08:57] <ReadError> looks like my router motor is arcing really bad
[15:08:59] <Icekiller> currently nothing.. but yea want tr12x3
[15:09:04] <ReadError> brushes going out you all think?
[15:09:16] <ReadError> i can see in to the top, looks like a little mini fire going on
[15:09:24] <ReadError> still seems to run good though...
[15:09:27] <Icekiller> and andypugh bk12/bf12 is overall for thi si think..
[15:10:57] <andypugh> Icekiller: It might turn out to be easier (and also maybe cheaper) to just buy the screws pre-machined.
[15:11:31] <Loetmichel> tjb1: sorry, my version of CD is to old
[15:11:41] <tjb1> Loetmichel: alright, thanks
[15:11:51] <Loetmichel> btw: the writing is not "closed"
[15:12:00] <Loetmichel> so not that easy to fill
[15:12:07] <Loetmichel> (lines are not connected)
[15:13:00] <Loetmichel> Icekiller: tr10*3 is SO cheap i have a packet of 2 metres bars here...
[15:13:09] <Loetmichel> whad end maschining do you need?
[15:19:58] <Loetmichel> Icekiller: i have a shop here whre the 2 meters bar of TR12*3 is less than 20 eur. (rolled)
[15:20:18] <Loetmichel> if you tell me what kind of end machining you need...
[15:27:27] <Icekiller> Loetmichel :
[15:27:29] <Icekiller> pm :)
[15:32:58] <r00t4rd3d> ReadError, thats what you get for buy thats cheap pos.
[15:33:05] <r00t4rd3d> -s
[15:33:50] <r00t4rd3d> hitachi wasnt it?
[15:33:55] <ReadError> yea
[15:34:00] <ReadError> but i put a ton of hours on it
[15:34:02] <ReadError> still runs strong
[15:34:08] <ReadError> besides it under warranty
[15:34:10] <ReadError> i can swap it out
[15:34:11] <r00t4rd3d> its only like 1 month old isnt it?
[15:34:17] <ReadError> nah man much older than that
[15:34:26] <ReadError> but ive broken mad bread with it so far
[15:35:00] <r00t4rd3d> is there replaceable brushes in the motor?
[15:36:39] <r00t4rd3d> some times the sparks happen when you get to the spring or clips holding them in place
[15:37:16] <r00t4rd3d> meaning they are worn to shit
[15:38:25] <ReadError> yea
[15:38:36] <ReadError> but, im not sure how to go about getting new ones
[15:38:46] <ReadError> it still runs tho
[15:38:58] <ReadError> i should pull em when this sheet is done
[15:38:58] <r00t4rd3d> it will eat a spring soon
[15:39:14] <r00t4rd3d> and probably ruin the armature.
[15:39:23] <ReadError> thats where the warranty comes in
[15:39:31] <r00t4rd3d> trade up for a dewalt
[15:40:31] <r00t4rd3d> you can order the replacement warning stickers on their website
[15:40:44] <r00t4rd3d> and everyother part
[15:45:02] <ReadError> no thanks
[15:45:10] <ReadError> i got the collets, dust collector, mount
[15:45:15] <ReadError> i dont see a point in switching.
[15:45:37] <ReadError> its easier to spend 90$ on a new one
[15:45:42] <ReadError> than 400 on all the other stuff
[15:46:18] <r00t4rd3d> what model hitachi?
[15:46:48] <r00t4rd3d> i thought the dewalt dwp611 and one hitachi model could use the same stuff
[15:48:27] <r00t4rd3d> 2.71 diameter and 1/4 collet
[15:53:06] <PCW> Brushes are about $5.00 -- $7.50 a set and should be easily available
[16:04:45] <largecheesepuff> well why doesn't spindle encoder is question of the hour
[16:07:13] <PetefromTn> What about spindle encoder.....Incidentally....I just received my SPINDLE encoder in the mail today YAY!! Rigid tapping here I come LOL....
[16:07:25] <PetefromTn> Happy dance...
[16:11:20] <largecheesepuff> yeah, I'm trying to understand why mine isn't work.
[16:11:23] <largecheesepuff> working
[16:11:59] <Connor> Bomb went off in Boston during a marathon.. Wow.
[16:12:07] <PetefromTn> Have you checked the input in Hal?
[16:14:25] <PetefromTn> Connor: Freakin' Bastards....
[16:14:53] <Connor> This isn't good... I don't know WTF is going on.. but.. this isn't good.
[16:14:55] <largecheesepuff> PetefromTn: I'm assuming I should be looking at spindle-index-enable?
[16:17:50] <PetefromTn> largecheesepuff: Actually not sure spindle enc input of some sort. I have not hooked mine up yet so I dunno.
[16:21:08] <largecheesepuff> yeah mine is hooked up I'm using 5I25 + 7i76
[16:21:44] <PetefromTn> Connor: Some sicko somewhere is probably enjoying himself right now.... While innocent people die and suffer. What the hell is wrong with the world today.
[16:21:59] <PetefromTn> largecheesepuff: Yup mine is the 5i25/7i77 combo.
[16:23:13] <Connor> PetefromTn: I dunno. kinda pisses me off..
[16:23:36] <PetefromTn> Kinda??!!
[16:24:08] <DJ9DJ> gn8
[16:48:31] <largecheesepuff> yup that seems like the right signal
[16:56:23] <andypugh> largecheesepuff: You need to wire up spindle.index-enable and spindle.revs (to the encoder position). There is also a spindle velocity pin to hook up too, though I think that is only used by lathes.
[17:09:30] <largecheesepuff> I'm setting it up on a lathe
[17:09:34] <largecheesepuff> but that info helps
[17:11:12] <largecheesepuff> I have position, velocity, and index-enable
[17:11:31] <largecheesepuff> setup in the Hal file.. pncconf seems to have taken care of that
[17:12:19] <largecheesepuff> position seems to work but index-enable doesn't seem to be work but I just check it with a scope and I've getting signal into the card
[17:12:47] <largecheesepuff> I figure it's something basic I missed.
[17:27:31] <JT-Shop> http://gnipsel.com/linuxcnc/tuning/encoder.html
[17:29:23] <Tom_itx> jt, how many tutorials do you have now?
[17:29:43] <JT-Shop> dunno

[17:35:08] <JT-Shop> n
[17:39:44] <andypugh> Hmm, I just found out that SK30 and BT30 are less similar than I thought.
[17:40:11] <andypugh> SK30 has a less-deep drive notch on one side, they don't actually fit in my spindle.
[17:40:46] <andypugh> So, do I attempt to deepen the nothches, take out one of the drive-dogs from my spindle, or shorten one of my drive dogs?
[17:41:14] <JT-Shop> what do you have more of?
[17:42:09] <andypugh> I have 25 SK30 and about 6 BT30.
[17:42:47] <JT-Shop> so if you modify the spindle to fit the SK30 the BT30's still work?
[17:42:49] <andypugh> And the BT30 will work with a shortened dog at least as well as the SK30 do, as the actual diameter is the same.
[17:43:22] <andypugh> Yeah, so I guess I just shorten one dog, if it isn't too hard to machine.
[17:43:29] <JT-Shop> aww another gantrykins problem on the forum
[17:43:35] <Tom_itx> which is a better fit for the application?
[17:43:55] <andypugh> Tom_itx: Nothing much in it.
[17:47:07] <Tom_itx> is 800F about right for RoHs soldering?
[17:47:19] <Tom_itx> getting some hotter tips for my iron
[18:37:07] * JT-Shop finally got the pump mount plate parallel to the engine mount plate
[19:46:17] <PetefromTn> ...
[20:10:30] <tjb1> JT-Shop: got a job at hardinge
[20:11:28] <PetefromTn> REALLY??!! NICE...
[20:13:37] <PetefromTn> Just tried to reinstall my Y axis ballscrew cover into the Cincinatti Arrow 500 retrofit and found that at the rearmost travel the guard would hit the mounts for the motor leads.... Thankfully I was prepared for this eventuality thanks to my pal LEE who said it might be an issue so I creeped it back there and did not mangle anything YEAY!!! Just removed the cover and had to notch some out of the side of it and it seems to fit
[20:13:37] <PetefromTn> good now. Now I can reinstall the cover and test it for clearance and if it clears I can put the rest of the table covers back on the machine finally....
[20:35:07] <LeelooMinai> Hmm... can I use an impact wrench (air) to drive normal screws?
[20:38:10] <Tom_itx> if you wanna pop the heads off
[20:38:45] <pcw_home> I was about to say 'maybe once'
[20:44:33] <LeelooMinai> Aha... any reason? I am googling and so far I think "probably"
[20:44:45] <PetefromTn> Really I do it quite often, I have a 3/8 butterfly impact and have used it to drive larger lag bolts and other things into heavy wood before several times. Works a treat.
[20:45:37] <LeelooMinai> From what I have read the difference is mostly that wrench has more power and usually larger attachement
[20:45:51] <LeelooMinai> So ... should work, I guess...
[20:48:39] <pcw_home> I guess it depends on the size of the impact wrench and the screw
[20:49:00] <PetefromTn> better yet is if you have a cordless drill with a clutch on it you can often set the clutch so you don't break the screw and drive away...
[20:51:03] <pcw_home> Since I do mostly do electronics, when you say screw its 4-40 or 6-32 or 3mm/.5
[20:54:22] <LeelooMinai> Nah, my mom decided I need to put marble tiles in the bathroof floor and I though of using impact wrench do drive a lot of wood screws:)
[20:58:57] <gammax> anything wrong with running steppers off a usb to parallel port converter?
[20:59:38] <pcw_home> no, unless you want more than a few hundred RPM
[21:00:35] <gammax> im lookin at max! 200 rpm
[21:01:04] <pcw_home> Possibly but not currently by linuxCNC
[21:01:49] <gammax> pcw_home, what do you mean by last comment?
[21:02:53] <pcw_home> linuxCNC has no step driver for USB devices as its not very practical since linuxCNC sets the timing
[21:03:57] <pcw_home> and a USB device would add a 1 ms jitter to the step generation
[21:04:11] <pcw_home> (best case)
[21:04:31] <gammax> ahhh ok... I think I may go with this.. http://www.amazon.com/Syba-Parallel-PCI-Express-Brackets-SI-PEX50054/dp/B00B5L9PF4/ref=sr_1_6?ie=UTF8&qid=1366076976&sr=8-6&keywords=parallel+port+low+pci-e
[21:05:39] <pcw_home> Yes, that will have predictable timing...
[21:09:43] <gammax> whats best way to control vfd? I have http://www.ebay.com/itm/270759117884?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649 that work?
[21:14:28] <pcw_home> Yeah if you VFD supported by linuxCNCs Modbus interface
[21:14:52] <pcw_home> s/you/your/
[21:15:48] <gammax> hmmm
[21:16:33] <pcw_home> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?VFD_Modbus
[21:17:01] <gammax> http://www.ebay.com/itm/270873771567?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649
[21:17:09] <gammax> thats what i got
[21:17:42] <gammax> wait, i take that back. on the mill i have an sj200
[21:22:04] <r00t4rd3d> shocker, Saudi national under guard in the hospital with a leg wound from the blast in Boston.
[21:22:26] <gammax> what a suprise
[21:22:31] <r00t4rd3d> i know
[21:23:24] <r00t4rd3d> i think more then half of the 911 hijackers were saudi, lets invade iraq!
[21:24:43] <gammax> I gave up. Went to the stan and my contracting career is now over thank god!
[21:25:57] <r00t4rd3d> what?
[21:26:22] <r00t4rd3d> wrong chan maybe
[21:26:31] <gammax> lol no correct one]
[21:26:47] <gammax> i gave up caring about those people.... for good or for bad...
[21:28:41] <tjb1> sorry PetefromTn, yes
[21:28:44] <tjb1> elmira
[21:29:57] <PetefromTn> Cool....Good luck man
[21:30:12] <r00t4rd3d> thanks, he'll need it.
[21:32:40] <gammax> did I miss something?
[21:34:06] <r00t4rd3d> earlier convo
[21:37:03] <largecheesepuff> one problem down... pretty exciting
[21:37:32] <PetefromTn> Been working some more on this monster here today. My machine has an air pressure regulator/oiler on the back of the machine. It has a low pressure sensor in there too. Well the damn thing has a small petcock on the bottom of the plastic cup that you fill with line oil. The fitting has a leak that I cannot stand and I am about to rip the damn thing off the wall. The oring inside the fitting that seals to the plastic cup was
[21:37:33] <PetefromTn> kinda cruddy so I replaced it with a new one and it still leaks a bit. At first I thought the little plastic screw was the problem as it does not have an oring on it. Tried some teflon tape on the threads and it helped a little but the problem is actually between the cup and the outside fitting. I am giving up for tonight but tomorrow I will probably try to machine a plug that I can stick inside the tube and try to seal it up
[21:37:33] <PetefromTn> that way. I will lose the ability to bleed off but really the thing works by just filling it up and if I have to purge it I will just remove the entire cup.
[21:37:48] <PetefromTn> largecheesepuff: what problem is that?
[21:39:28] <tjb1> r00t4rd3d: did you see earlier
[21:40:01] <largecheesepuff> PetefromTn: forward and reverse acting weird on the lathe
[21:40:27] <PetefromTn> largecheesepuff: define....wierd.
[21:41:40] <largecheesepuff> PetefromTn: at max of 2000 rpm M3 S500 worked but m4 s500 would run at 1500rpm
[21:41:45] <PetefromTn> Sweet lathe for sale in Clinton TN for a reasonable price I think... If I was not dead set on a CNC lathe I would be calling them right now.http://knoxville.craigslist.org/tls/3745161761.html
[21:42:07] <jdh> nice
[21:42:22] <PetefromTn> yep...
[21:42:23] <jdh> that's a lot of iron
[21:44:26] <largecheesepuff> PetefromTn: essentially scaling the analog encoder backwards
[21:44:42] <PetefromTn> largecheesepuff: The settings in my machine initially did not let the spindle run backwards despite my checking and verifying the outputs were correct. We found that the output was going negative and had to change the settings to only output positive numbers. Obviously not what your machine is doing but it points to the same direction. I would start by removing the output wires and verifying the output voltage is correctly
[21:44:42] <PetefromTn> scaled to your input selection
[21:45:20] <pcw_home> largecheesepuff: What hardware
[21:45:29] <largecheesepuff> PetefromTn: it's actually corrected PCW on the forums helped out
[21:45:34] <PetefromTn> jdh: Actually they are not really that big. They are probably one of the prettiest lathes ever made tho...
[21:45:47] <jdh> yeah, I've seen a few.
[21:45:51] <PetefromTn> Oh okay just trying to help...
[21:45:57] <jdh> 3000lbs is a lot of iron in that little package
[21:46:49] <largecheesepuff> PetefromTn: it was issues in the hal file. I just used pncconf to configure everything and it didn't seem to handle that correctly
[21:47:45] <PetefromTn> largecheesepuff: Yeah I know we basically only used the PNCconf for the basic setup and then Connor was able to help me learn sorta how to find my way around in the hal and INI files. Once you understand that it is easier I think.
[21:47:53] <largecheesepuff> PetefromTn: I still need to trouble shoot the spindle encoder which isn't work but I'm saving that for tomorrow
[21:47:57] <PetefromTn> jdh: yeahh man sure is...
[21:48:35] <largecheesepuff> err sp work/working
[21:48:56] <PetefromTn> largecheesepuff: That's my basic philosophy on this build, take it one circuit and step at a time. What's the old adage, how do you eat an Elephant.....one bite at a time LOL.
[21:49:44] <largecheesepuff> yeah, I finally managed to start wrapping my head around tool setup on gang tool style lathe
[21:49:51] <pcw_home> largecheesepuff: You might mention this pncconf issue in the
[21:49:53] <pcw_home> pncconf section of the forum (need add unipolar analog spindle out option)
[21:50:04] <pcw_home> need to add
[21:50:07] <largecheesepuff> over the weekend, after reading for hours.
[21:50:29] <PetefromTn> Yeah don't ya just use tool offsets in multiple axes?
[21:50:58] <sparr> Are there open source slicing/toolpath programs that can handle more than 3 axes of motion? Particularly for machines with a table that can tilt?
[21:51:29] <largecheesepuff> pcw_home: Yeah, I'll mention it on the forums.
[21:57:20] <PetefromTn> Anyone ever heard of using a hot water heater element as an braking resistor for a VFD? I heard it will work actually and was considering trying it for my VFD> Elements are like $25.00 and the braking resistors I need are in the $150.00 range....
[21:58:08] <largecheesepuff> it's a high wattage resistor
[21:58:27] <largecheesepuff> harder thing is finding the correct ohms but that is easy enough to calculate
[21:58:31] <PetefromTn> Yes I suppose it is...
[21:58:44] <pcw_home> A stove top element works also
[21:58:45] <PetefromTn> Yeah my pal Art has already done that for me for the most part.
[21:58:59] <PetefromTn> Pete have you ever seen one used that way?
[21:59:05] <pcw_home> Yes
[21:59:27] <PetefromTn> Just how hot do they get would you say for a spindle brake setup?
[21:59:51] <PetefromTn> We talking glowing red here or just dissipating some heat and then quickly cooling.
[21:59:55] <pcw_home> They work fine but you need a cage to prevent accidental comtact
[22:00:05] <largecheesepuff> seems easy
[22:00:30] <largecheesepuff> you can always add a fan if needed to dump more heat
[22:00:32] <pcw_home> never glowing red, but definately a burn hazard
[22:00:49] <PetefromTn> Actually there is a cage in the machine already that I initially removed to make into my computer enclosure. I have since installed the computer up front so I can reinstall that if need be.
[22:01:54] <PetefromTn> Also was considering drilling some holes into the electronics enclosure and installing the resistor on the outside of the cabinet between it and the mill column inside some kinda steel cage. That would keep the heat out of the electronics cabinet...
[22:03:41] <FinboySlick> pcw_home: You mentioned SRL32s the other night, mind if I pick your brain a tad?
[22:03:51] <PetefromTn> Won't a traditional braking resistor create similar heat? I mean the energy has to go somewhere and that is what a resistor does after all, bleed off energy in the form of heat. Maybe it is not as efficient at heating up as the element would be?
[22:04:12] <pcw_home> The energy will be the same
[22:05:35] <pcw_home> excess kinetic energy dumped into heat (same heat as a brake doing the same job)
[22:05:47] <FinboySlick> pcw_home: Documentation speaks of 32bit input and width up to 1024bits.
[22:06:16] <pcw_home> Big fancy drives dump it back into the power lines
[22:06:37] <PetefromTn> So in your opinion the heat created for the same amount of energy dump will be the same regardless of the resistor then?
[22:06:46] <pcw_home> Yes
[22:07:06] <PetefromTn> LOL I thought I bought a big fancy drive, I mean it is a Hitachi 15HP!!
[22:07:11] <pcw_home> A higher value resistor will take longer
[22:07:45] <pcw_home> VFDs get very big
[22:07:47] <PetefromTn> So therein lies the importance of proper sizing...
[22:07:50] <L84Supper> pcw_home: any news on a Zynq FPGA + PCIe + DDR3 board?
[22:08:19] <PetefromTn> yes they do I was just kidding. I've seen motors and VFDs in the hundred of HP range online...
[22:08:32] <pcw_home> working on it (though no PCIE)
[22:09:01] <PetefromTn> Whats the difference between PCI and PCIE?
[22:09:09] <L84Supper> have they announced pricing yet on the Zynq parts?
[22:09:16] <pcw_home> Too low a value will overload the braking transistor
[22:09:55] <pcw_home> Ive seen some leaked info (Avnet posted prices then removed them)
[22:10:25] <L84Supper> http://www.xilinx.com/products/boards-and-kits/DK-Z7-VIDEO-G.htm 5 week lead time for this board
[22:13:12] <L84Supper> http://www.xilinx.com/products/boards-and-kits/EK-Z7-ZC706-G.htm only 2 weeks on the eval kit
[22:14:54] <PetefromTn> Yeah I will speak with Art about it, unless you have some ideas about proper sizing. Basically I have a 270 volt 5.5kw motor 7.5HP and I think it is 18.5 amps at 50/60hz. We will of course be at 60...
[22:16:28] <pcw_home> input voltage?
[22:17:12] <PetefromTn> 220vac
[22:17:29] <PetefromTn> Sorry..
[22:19:54] <PetefromTn> I am looking to get an edge finder to use until I can get a proper probe built or bought for the machine, Was considering using one of the 3/4 shank electronic edge finders temporarily until I can get something better. Something like this...http://www.ebay.com/itm/PRECISION-ELECTRONIC-DIGITAL-EDGE-FINDER-CNC-MILLING-/330518419131?pt=LH_DefaultDomain_0&hash=item4cf46ed6bb.
[22:21:53] <pcw_home> the brake resistor runs off the DC bus which will be about 320V
[22:21:55] <pcw_home> so the power in the load will be about twice what it is at 220 VAC
[22:21:57] <pcw_home> so a 2 KW 220V heater will dissipate about 4 -5 KW when on
[22:21:59] <gammax> what guage wire would you guys use for a 25ft run to a cnc lathe?
[22:22:36] <gammax> vfd in there connected to motor
[22:22:57] <PetefromTn> What size motor and what is the total amperage...
[22:23:12] <gammax> 1.5
[22:23:16] <gammax> total amps unk...
[22:23:23] <gammax> im assuming under 10 though...
[22:23:33] <L84Supper> #12
[22:23:54] <PetefromTn> Pete, so if I find an element that is 2kw 220 I should be fine then?
[22:24:21] <pcw_home> Yes
[22:24:26] <gammax> you guys talking about breakin resistors?
[22:24:54] <pcw_home> we ain't breakin no resistos
[22:25:10] <gammax> lol
[22:25:18] <gammax> I need to choose one...
[22:26:20] <LeelooMinai> Hmm... is there a way one can cut at home 1/4 inch structural steel angle? :)
[22:26:54] <PetefromTn> Silly question, can I go TOO BIG? I mean will a larger one dissipate the heat better there is a 5.5kw one at Home depot for like $20.00
[22:27:10] <PetefromTn> sure hacksaw...LOL
[22:27:22] <PetefromTn> Just better workout your arms first...
[22:27:27] <LeelooMinai> I was just going to add - without spanding a day hacksawing it:)
[22:28:04] <PetefromTn> You can buy one of the cheap chinese 4x6 bandsaws and they work pretty good.
[22:28:30] <gammax> LeelooMinai, plasma cutter...
[22:28:35] <pcw_home> The VFD should have a minimum resistance/max current spec
[22:28:35] <gammax> angle grinder...
[22:28:38] <PetefromTn> You can also get an abrasive chop saw but they are loud, create a ton of heat, and usually mushroom the metal.
[22:28:46] <LeelooMinai> I have a bandsaw... But I am pretty sure that the band it has is only for wood
[22:28:59] <PetefromTn> Angle grinder with cutoff wheel would work but take forever.....
[22:29:01] <gammax> LeelooMinai, try and find out :)
[22:29:29] <PetefromTn> Wood bandsaw won't work you will melt the tires on the wheels and wind up breaking your saw...
[22:29:34] <gammax> PetefromTn, I disagree... a quality cutoff wheel not Harbor friehgt would slice through it pretty fast...
[22:29:43] <LeelooMinai> Well, I guess I will leave it to metal market to cut it. Though they wrote me that they can cut only as accurate as the tape measure they have... which is supposedly 1/8 inch
[22:29:56] <PetefromTn> gammax: He said 1/4 inch thick angle.....
[22:30:10] <gammax> I know lol
[22:30:11] <LeelooMinai> I am not a "he" btw
[22:30:12] <PetefromTn> I said it would cut it but take awhile and eat up some disks...
[22:30:36] <gammax> LeelooMinai, your a he/she?
[22:30:38] <PetefromTn> Ooh do tell, nice to meet ya leeloo...
[22:30:43] <LeelooMinai> I have some of those disks and a grinder, but, I don't think that would create a nice cut:)
[22:31:06] <gammax> if you had a nice chop saw...
[22:31:28] <gammax> had one at the power plant I used to work at... had a chain to hold the peice down and then the sparks flew
[22:31:30] <LeelooMinai> I have mitre saw and I bough alu blade, but that's for non-ferrous metals
[22:31:37] <PetefromTn> Just do yourself a favor and take it to a welder or metal supplier and have them cut it for you...
[22:32:03] <PetefromTn> If you were close I would cut it for you LOL
[22:32:13] <LeelooMinai> Initially IO planned to build my cnc frame from alu only, but recently I reconsidered and now it will be mixed alu/steel, but all I can do with steel is drill holes:)
[22:32:31] <PetefromTn> So leeloo from the fifth element?
[22:32:55] <LeelooMinai> Right, that's the nick I had for years
[22:32:59] <pcw_home> big bada boom
[22:33:15] <PetefromTn> How cool is a chick that builds CNC routers and stuff....
[22:33:16] <LeelooMinai> Hmm... I guess I will let them cut the steel parts and try not to rely on their length
[22:33:40] <PetefromTn> If they are worth their salt they SHOULD be able to cut it accurately....
[22:33:46] <gammax> leeloo why not replace band saw blade?
[22:33:54] <PetefromTn> Multipass....
[22:34:28] <LeelooMinai> gammax: Well, to be honest cutting like 4inch angle with bandaw scares me a bit:)
[22:34:58] <LeelooMinai> I would save only few dollars probably per piece
[22:35:10] <LeelooMinai> Maybe it's not a good idea...
[22:35:16] <gammax> LeelooMinai, im a do it yourselfer..
[22:35:37] <LeelooMinai> I am too, but there must be a line somewhere:)
[22:35:39] <PetefromTn> Best probably to look on craigslist for a used metal cutting bandsaw for cheap I see them all the time. You will use it a LOT if you are building a machine...
[22:36:26] <gammax> I picked up a horizontal/vertical with new blade for 20 bucks in california! lol all I had to do was tighten everything up!
[22:36:27] <LeelooMinai> PetefromTn: My plan was using my mitre saw + this nice alu cutting blade I bought to handle all the aluminum parts - beams mostly
[22:37:02] <gammax> LeelooMinai, cant you just attache a huge grinding wheel to it?
[22:37:38] <LeelooMinai> Hmm... to 8.5inch mitre saw? :)
[22:37:53] <LeelooMinai> http://i.imgur.com/FHhriVz.png <- I am still designing the frame, but this is more or less the plan
[22:37:54] <PetefromTn> LeelooMinai: I have cut a lot of metal and while you can cut aluminum with a wood cutting mitre box it is less than ideal and not a little dangerous. The metal cutting saws are usually slower moving blades and have safety guards in place for the chips.
[22:38:59] <LeelooMinai> PetefromTn: Hmm... I thought aluminum is not that hard and this blade is carbide-tipped and good brand
[22:39:48] <gammax> LeelooMinai, ive cut aluminum with many differant type of saw... prolly not the safest but when I did.... I always used a type of grease to cut it....
[22:40:02] <LeelooMinai> Cutting oil probably
[22:40:06] <PetefromTn> LeelooMinai: It is not that hard depending on the alloy I am just saying it is a higher speed saw and will not be pleasant to use while you are cutting with it. It will probably throw hot chips all around and it sucks..
[22:40:11] <LeelooMinai> I read about those few weeks ago
[22:40:34] <PetefromTn> Where are you located?
[22:40:44] <LeelooMinai> Canada/Ontario
[22:40:49] <gammax> ehhh
[22:42:00] <LeelooMinai> PetefromTn: Maybe I will do the cutting on the deck outside and protect myself somehow
[22:42:50] <LeelooMinai> I could look into those saw bands, but I thought a mitre saw blade would create more flat cuts (?)
[22:43:22] <PetefromTn> Check out your local chinese tool supplier busybee or something like that I think and see if they have that small bandsaw... you will wind up loving it and it is much safer and can cut steel or aluminum with ease and relatively precisely if you set it up right...
[22:43:54] <LeelooMinai> Right, thx, I will investiage this
[22:46:05] <PetefromTn> Good luck Leeloo dallas multipass...
[22:57:07] <PetefromTn> gammax: Here is a little wire gauge help....https://www.icmag.com/modules/Tutorials/ElectricalSafety/1655.htm
[22:57:54] <gammax> nice thanks
[23:00:08] <gammax> anyone have a wiring scematic for a hardinge hc? :)
[23:13:06] <r00t4rd3d> holy fuck there is some nasty pictures of that boston shit
[23:13:32] <r00t4rd3d> NSF-ANYTHING!!!!! http://imgur.com/a/IuEDd
[23:13:42] <r00t4rd3d> dont look if you dont like that kinda stuff
[23:16:57] <r00t4rd3d> not that i like that kinda stuff but i can stomach it
[23:17:16] <r00t4rd3d> while eating pasta
[23:18:26] <r00t4rd3d> everyone having a smart phone with a decent camera in it sure has changed the world
[23:50:02] <gammax> r00t4rd3d, pretty sick!
