[00:50:41] <Jymmm> mhaberler: is guest you?
[00:51:09] <mhaberler> guest? where?
[00:51:28] <Jymmm> mhaberler: Is this you --> guest45674t has joined (guest45674@ip70-179-55-149.sd.sd.cox.net
[00:51:38] <mhaberler> nope
[00:51:52] <Jymmm> Ok, been bouncing for hours
[00:52:04] <archivist> cox is your side of the pond Jymmm
[00:52:14] <mhaberler> ah, I see the connection.. somebody else is piano player today
[00:52:31] <archivist> I think he is a noob on wifi
[00:52:52] <archivist> he asked real questions on arrival
[00:52:54] <r00t4rd3d> you can hide join/part notices
[00:53:09] <Jymmm> guest45674t: Your connection has been bouncing for hours. Please fix it and change your nick to get back into the channel. Thanks!

[01:12:37] <Jymmm> I wish there was a Torroids-R-Us locally =)
[01:13:04] <Jymmm> or web with everyday free shipping!
[02:09:38] <Connor> Anyone still awake ?
[02:13:40] <psha[work]> good morning :]
[02:24:34] <Jymmm> I'm wonderinf if this is a good idea or not... I have a 15W soar blanket/panel (http://www.affordable-solar.com/store/archive-portable-solar-panels/unisolar-uni-pac15-15-watt-foldable-flexible-solar-panel) and I'm thinking of feeding it into step up booster (http://www.ebay.com/itm/DC-DC-100W-3-35V-to-3-5-35V-Boost-Step-up-Module-Power-Supply-LED-Voltmeter-/170905602162?pt=LH_DefaultDomain_0&hash=item27cac48872) to charge these batteries I
[02:24:34] <Jymmm> just got (http://www.gearxs.com/HYPE-Universal-External-Netbook-Notebook-Battery?keyword=hy-2021-lb)
[02:25:17] <Jymmm> The idea is to still have enough juice even at sunset to not start a new charge cycle on the batteries
[03:59:51] <DJ9DJ> moin
[04:09:41] <Jymmm> ug
[04:09:53] <Jymmm> DJ9DJ: you're way late today =)
[04:12:59] <DJ9DJ> indeed :D
[04:13:01] <DJ9DJ> hi Jymmm
[07:56:42] <MrTrick_> evening, #emc
[07:57:28] <MrTrick_> I'm wondering - if I have a program that dynamically generates G-code, can I programmatically run EMC2?
[08:02:27] <MrTrick_> Also, can EMC2 work with the EiBotBoard? (USB serial interface, takes commands in the form "MC,dt,Xpos,Ypos\n" instead of needing step signals)
[08:06:47] <micges> hi MrTrick_
[08:07:34] <micges> no linuxcnc don't send any serial commands instead of pulses
[08:08:09] <MrTrick_> damn.
[08:08:13] <micges> but you can always write this part of code
[08:08:25] <MrTrick_> What about a program (java, say) making EMC2 jump?
[08:09:33] <micges> starting emc is simply issuing 'emc path/to/ini'
[08:09:49] <micges> if you can do this in your program then you can start emc
[08:10:10] <MrTrick_> and being able to generate some g-code and feed it to emc?
[08:12:09] <micges> after axis starts you can use axis-remote to remotely load gcode file
[08:12:10] <micges> http://www.linuxcnc.org/docs/html/gui/axis.html#_axis_remote
[08:12:53] <MrTrick_> ah, interesting.
[08:13:13] * MrTrick_ contemplates whether to build his own motion controller
[08:15:18] <MrTrick_> micges: It's for a plotter that operates continuously and automatically, for about two weeks straight.
[08:15:36] <MrTrick_> and then will be retired.
[08:16:31] <micges> why can't you use emc2 step/dir?
[08:18:14] <MrTrick_> well, my main concern is not knowing how difficult it's going to be integrating the rest of the program with emc.
[08:24:42] <MrTrick_> and emc2 step/dir is a parallel-port thing only, and I'm not sure whether the other software that has to interact with this program is windows-only.
[08:28:50] <micges> what is the 'other software'?
[08:29:37] <MrTrick_> something someone else is writing. ^_^
[08:30:00] <MrTrick_> basically, my domain is 'accept line of text, render and plot'
[08:31:58] <micges> if this 'other' is windows program then you could have problem to use emc2
[08:35:11] <MrTrick_> well yes. That's why I'm tempted to abandon emc2 and write my own motion control code.
[08:35:28] <MrTrick_> The robot is a fairly simple 2.5D plotter.
[08:58:37] <r00t4rd3d> emc has been renamed to LinuxCNC
[08:58:55] <r00t4rd3d> incase you missed that
[08:59:52] <MrTrick_> yes. yes it has. ^_^
[10:12:56] <r00t4rd3d> just tore my z axis apart, noticed it had a 1/16 of play develop some how
[10:14:08] <r00t4rd3d> well i think i know how, i crashed it slightly about a week ago
[10:16:07] <r00t4rd3d> i was trying a 0.025 engraving and I kept getting different depth results
[10:38:57] <Dolence> hi! :D
[10:40:16] <Dolence> please, anyone could give some info regarding linuxcnc and touchscreen lcd? thanks in advance
[10:43:01] <r00t4rd3d> sounds like an accident waiting to happen
[10:44:16] <r00t4rd3d> http://www.cnczone.com/forums/linuxcnc_formerly_emc2/92072-new_gui_touchscreen_no_keyboard.html
[10:47:49] <r00t4rd3d> seems like you want to use the Touchy gui
[10:48:17] <r00t4rd3d> http://linuxcnc.org/docs/html/gui/touchy.html
[10:48:52] <r00t4rd3d> Dolence, ^^
[11:03:09] <Dolence> r00t4rd3d i managed to load touchy, but I dont understand it very well
[11:03:50] <Dolence> I don't know how to load jobs to it
[11:06:35] <r00t4rd3d> cradek would be the one to ask probably
[11:07:15] <r00t4rd3d> I dont see many people talking about Touchy
[11:08:25] <r00t4rd3d> or i guess skunkworks has screwed with it too
[11:09:02] <skunkworks> very little
[11:10:28] <r00t4rd3d> yeah googling i just seen you mention it
[11:10:32] <tjb1> Anyone know a cheap place to get an 8mm reamer
[11:10:33] <Loetmichel> re @ home
[11:11:08] <Dolence> skunkworks could you tell me how i'm suposed to load files and start a job with touchy? I'm pretty new to all this CNC world
[11:11:58] <skunkworks> well - you do need a certain amount of hardware for it... (like a cycle start button)
[11:12:42] <skunkworks> Dolence, start here... http://linuxcnc.org/docs/2.5/html/gui/touchy.html
[11:13:31] <archivist> tjb1, what was/is J&L tools? depends what you mean by cheap http://www.mscdirect.co.uk/CGI/INSRCH?ns=1&oldNtt=reamer&oldNtk=Keyword+Search&oldURLVar=0921088682895D257DF964A91AA36184EBD8220AD3A8D040C362C546B92F4A16817816ADCE0ACF80247A85C925C9DA74EB99B36CEDBF6E537ED4BADC1D20953AF1376073548A1662FD0790ACE588A64ACBB604A9E32DCCEB03589A22949E39721959292B97CB1F236FFAB1C2ED0694C33068B9D01A98B39C4369F5D72F6CC04C620FB8FA32045C77F41D
[11:13:31] <archivist> 47410E7C0B412943AD2816C716718B702C6CF94BB9DE138541D5AE233F6918A55FB5E391DA4A12C691FB2AF0CC2CD928985CBCD71D2A7F134C35FED76B5E27273796687CF5FD5C5B97AA4A483295DD65D2858EFB9BE009C43D86FE8EA5A634D496313316F42A39780A4DA59F14E85C80597CB5037A24&scrNtt=reamer+8mm&x=0&y=0&Ntk=Keyword+Search
[11:14:02] <archivist> wonderful link :)
[11:14:13] <tjb1> like $10 range
[11:15:37] <archivist> ebay
[11:16:02] <tjb1> that I can get before the end of next week lol
[11:16:13] <Dolence> I dont get it... I have to attach hardware buttons to have a fully functional touchscreen interface? I mean, it's suposed to be touchscreen...
[11:16:42] <Dolence> i think i will stick to Axis
[11:16:50] <tjb1> Dolence: "Touchy is a user interface for LinuxCNC meant for use on machine control panels, and therefore does not require keyboard or mouse.
[11:16:50] <tjb1> It is meant to be used with a touch screen, and works in combination with a wheel/MPG and a few buttons and switches."
[11:17:25] <tjb1> 3 buttons and a wheel required
[11:18:13] <Connor> How big a deal is it to have a motor pulley slightly over-bored? shaft is 17mm, the pulley is 17.17mm
[11:18:17] <archivist> getting touch screens working can be entertaining
[11:18:22] <Dolence> now I understood, thank you tjb1
[11:18:36] <Dolence> actyually I have Elo touch working flawlessly
[11:18:47] <Dolence> *actually
[11:19:10] <Dolence> but the idea of having buttons to complement a touchscreen interface sounds not logic to me
[11:19:11] <archivist> Connor, adjustable reamer
[11:19:32] <Connor> archivist: Yet another tool I don't have.. and little too late..
[11:19:53] <archivist> reamer is less than a lathe :)
[11:20:34] <Connor> I used the lathe. :(
[11:20:55] <Connor> and miss calculate or something.. I'm .17mm too large
[11:21:02] <archivist> and got it undersized?
[11:21:19] <Connor> No. Shaft is 17mm, pulley hole is 17.17mm
[11:21:37] <Connor> I slightly over-bored it by .17mm
[11:21:43] <archivist> cockup will be a bit out of balance
[11:21:58] <Connor> cockup ?
[11:22:50] <tjb1> One instructor told me to grind a O drill down a thousands and ream with it
[11:22:59] <archivist> http://www.phrases.org.uk/meanings/cock-up.html
[11:23:05] <tjb1> Try that before I blow $30 on a reamer
[11:23:40] <r00t4rd3d> goto a heating place that sells furnaces and get a orifice reaming kit
[11:24:16] <archivist> I better hide my reamers
[11:24:25] <Connor> archivist: So, it might be a tad out of balance.. I spun it up with the motor last night.. couldn't really fill anything except a super low speeds
[11:25:18] <r00t4rd3d> they sell adjustable orifice reamers too
[11:25:32] <Connor> other option is to swap my pulleys out.. they're basically the same. Both need to be bored out.. this one had 2 set screws in the boss, which is needed for the motor.. the other had no set screws in any of it..
[11:25:35] <syyl_ws> ever hit the actual size with an adjustable reamer? :D
[11:25:37] <syyl_ws> me not
[11:26:01] <archivist> I have hit size, boring though
[11:26:06] <syyl_ws> "ok a bit more"..."and a bit more..".."once more"..."damn, to big"
[11:26:24] * syyl_ws pulls his hat
[11:26:38] * r00t4rd3d tugs his reamer
[11:26:40] <syyl_ws> i prefer a boring head/boring bar...or a fixed size reamer
[11:26:50] <archivist> depends on ones definition of size :)
[11:26:53] <Connor> Well, in my defense.. I'm use to using the mini-lathe in inches.. but.. tried this in metric since the hand-wheel has both marks.
[11:27:02] <Connor> I just think I miss counted or something.
[11:27:02] * syyl_ws hugs his reamer-kit
[11:27:14] <syyl_ws> 1 up to 18mm :D
[11:27:37] <Connor> How's that going to help ?
[11:27:49] <archivist> I has adjustable set 1/2" to 1 1/4" plus others
[11:28:06] <syyl_ws> for a dirty rescue
[11:28:14] <syyl_ws> you can wrap the shaft with shim stock..
[11:28:17] <r00t4rd3d> get a fat sewing needle
[11:28:17] <Connor> oh, you have 1 up to 18mm.. I was thinking you were saying up the size to 18mm..
[11:28:18] <archivist> Connor, or over bore some more and sleeve
[11:28:37] <r00t4rd3d> use your penis
[11:28:45] <Connor> r00t4rd3d: Grow up.
[11:28:50] <r00t4rd3d> Nope/
[11:28:52] * archivist admits to the shim fix a few times
[11:29:05] <syyl_ws> or weld the bore up und remachine ;)
[11:29:18] <syyl_ws> or put a few massive centre punch marks on the shaft..
[11:29:21] <Connor> It's aluminum.. and I don't have a welder.
[11:29:27] * syyl_ws runs away
[11:29:49] <Connor> piece of paper or tape would be thick enough for a shim..
[11:29:56] <Connor> not sure how long it would last..
[11:30:00] <archivist> knurl the shaft
[11:30:19] <syyl_ws> 0.17 more diameter by knurling?
[11:30:27] <Connor> .17MM
[11:30:35] <Connor> That's what .007"
[11:30:46] <syyl_ws> dont know, i am metric :D
[11:30:49] <Connor> so, .0045" on either side..
[11:31:09] <archivist> it would be brutal knurling :)
[11:31:29] <syyl_ws> common technique
[11:31:39] <syyl_ws> "we enlage the shaft by brutal knurling.."
[11:31:41] <syyl_ws> ;)
[11:31:57] <syyl_ws> hmm
[11:32:05] <Connor> wait.. math wrong. .0035"
[11:32:29] <syyl_ws> best way would be to bore the pulley out
[11:32:38] <syyl_ws> and glue/shrink/pressfit a sleeve
[11:34:07] <Connor> or, swap the pulleys out.. only diff between them is like I said.. one has the set screws in the Boss of the pulley, the other has no set screws at all. I over-bored the one with the set screws. The other has to be bored out way larger that 17mm
[11:34:08] <archivist> at the last job we did the knurling trick in production for clock winding keys
[11:35:19] <archivist> you could taper bore in the pulley and make a taper adjustable bush with pulling in device
[11:35:33] <archivist> works rather well
[11:36:28] <syyl_ws> very elegant solution :)
[11:37:46] <archivist> very good grip on the shaft too, far better than grub screws
[11:40:05] <tjb1> Might grab one off amazon
[11:40:11] <tjb1> $22 and $4 to get it here tomorrow
[11:40:28] <Connor> grab what ?
[11:40:42] <tjb1> reamre
[11:40:44] <tjb1> reamer
[11:46:37] <Dolence> ayone using gscreen as UI?
[11:48:18] <tjb1> Im thinking grinding this O drill will work
[11:48:21] <tjb1> Its already 7.99mm
[11:48:41] <tjb1> knock a tad off and good to go
[11:48:58] <Connor> tjb1: What are you trying to do ?
[11:49:08] <tjb1> make an 8mm hole for a dowel pin
[11:49:33] <Connor> ah.
[11:49:53] <Connor> could polish the dowel pin down.
[11:51:19] <r00t4rd3d> tjb1, get a sewing needle
[11:51:56] <tjb1> Guess I should wait until I have the dowel pin
[11:52:04] <tjb1> Whats a sewing needle going to do?
[11:52:20] <r00t4rd3d> act as a reamer
[11:52:48] <r00t4rd3d> or cut the head off a finish nail
[11:52:57] <r00t4rd3d> put it in a drill
[11:53:06] <tjb1> Where am I going to get an 8mm needle?
[11:53:19] <tjb1> That probably cost as much as the reamer
[11:53:32] <r00t4rd3d> they make fat ones, try joanne fabrics
[11:53:45] <tjb1> 8mm is .315"
[11:53:49] <tjb1> Thats pretty fat
[11:53:56] <r00t4rd3d> they make them for yard and stuff
[11:54:00] <r00t4rd3d> yarn*
[11:54:28] <r00t4rd3d> or just buy an 8mm drill bit
[11:54:36] <Connor> 8mm drill won't work.
[11:54:40] <Connor> it'll be oversized.
[11:54:48] <r00t4rd3d> so a 6mm
[11:54:58] <Connor> He's already at 7.99mm
[11:55:09] <tjb1> Im gonna grind this drill bit and keep checking it in a scrap
[11:55:26] <Connor> tjb1: Could chill the pin in Freezer.. :)
[11:55:49] <tjb1> Only reamer we have is 5/16
[11:55:55] <tjb1> can I get it down to that? :P
[11:56:35] <Connor> I bet you can.. that's VERY small amount.
[11:56:49] <tjb1> 2.5 thousandths
[11:57:08] <tjb1> That would work nicely
[11:57:31] <Connor> 0.000393701"
[11:57:41] <tjb1> ?
[11:57:43] <Connor> 7.99 from 8 is .01mm which is 0.000393701
[11:57:47] <Connor> in inches
[11:57:51] <tjb1> I dont have a 7.99mm hole
[11:57:59] <Connor> Oh, I thought you said you did.
[11:58:05] <tjb1> I have a drill that measures 7.99 with a caliper
[11:58:12] <Connor> Oh.
[11:58:15] <tjb1> I can make a hole .3125
[11:58:44] <cradek> you can't measure .01mm with a caliper!
[11:59:07] <tjb1> Thats what it says, I would use my mic but I would have to convert :P
[11:59:37] <cradek> are you going for a tight or loose fit for your dowel pin?
[11:59:45] <tjb1> press
[11:59:52] <tjb1> or freeze and expand
[12:00:05] <Connor> Well.. drill bit @ 7.99mm will drill out larger..
[12:00:06] <cradek> ah then if you drill with that 7.99 drill the dowel will fall through :-)
[12:00:51] <tjb1> drill bit is .3143
[12:01:09] <tjb1> which is 7.98322mm
[12:01:23] <cradek> yeah still too big
[12:01:39] <tjb1> im gonna put it in a surface grinder and take some off
[12:01:42] <cradek> if you want a press fit you need a round hole anyway - no drill will give you one
[12:01:53] <tjb1> its just to hold a bearing
[12:02:30] <tjb1> http://www.cncrouterparts.com/images/Extended%20Linear%20Carriage%20ABEC%207.jpg
[12:02:35] <tjb1> the 2 bearings inside the block
[12:03:11] <cradek> if the bearing ID is 8mm an 8mm DP won't go in easily
[12:04:25] <tjb1> it may be a 5/16 dowel
[12:05:58] <tjb1> I may just use a 5/16
[12:06:04] <tjb1> its not THAT important.
[12:12:47] <IchGuckLive> Hi all
[12:14:32] <Dolence> please, how do you guys convert dxf/dwg to cnc script? I saw some python script, but I think linuxcnc already have something like this...
[12:14:49] <IchGuckLive> Heekscad
[12:15:34] <IchGuckLive> http://www.youtube.com/watch?v=zEBXlJj45rE
[12:15:46] <IchGuckLive> DXF is from ?
[12:15:52] <Dolence> ty, from Corel
[12:16:09] <IchGuckLive> why not from librecad or Qcad its all free
[12:16:46] <IchGuckLive> is it a simple 3Axis
[12:17:05] <Dolence> because I'm using linux only on CNC machine
[12:17:12] <IchGuckLive> ah ok
[12:17:22] <IchGuckLive> Heekscad is also on Windows
[12:17:37] <IchGuckLive> look at my tutorials
[12:17:47] <IchGuckLive> is it a Mill or ?
[12:17:48] <Dolence> I will try it right now!
[12:17:53] <Connor> Dolence: What your talking about is CAM. Most of the time CAM is done on the same machine that you do the CAD work on.
[12:18:12] <Connor> not, on the CNC controller.
[12:18:21] <IchGuckLive> Connor No Cad = no CAM
[12:18:24] <Dolence> hmmm, and them I send the already covnerted file to CNC
[12:18:33] <IchGuckLive> yes
[12:18:55] <IchGuckLive> Dolence: ? mashine type
[12:19:01] <Connor> dxf/dwg is cad.
[12:19:16] <IchGuckLive> Yes
[12:19:26] <Dolence> cnc router
[12:19:43] <Connor> Dolence: Did you CAD out your drawings ?
[12:19:49] <IchGuckLive> Depending on mashine type you need Diferent CAM or Postprozessors
[12:19:52] <Dolence> wait, my english isnt that good and i'm sorry for that, let me explain
[12:20:07] <IchGuckLive> Where Are You from
[12:20:29] <Dolence> from Brasil
[12:20:29] <IchGuckLive> Europ ,Asia
[12:20:34] <Dolence> south america
[12:20:37] <IchGuckLive> oh Portugise
[12:20:40] <Dolence> yeah
[12:21:03] <IchGuckLive> so why on Linuxcnc not on MACH3 iff you are a Windows Man
[12:21:17] <jdh> c'mon, that was uncalled for.
[12:21:32] <Dolence> me and my uncle work together, doing some "inventions" like filling machines, etc
[12:21:47] <Dolence> I have to bea linux man to use linux os?
[12:21:47] <IchGuckLive> ok
[12:22:08] <Dolence> on my house i am using Mac OS X, linux (NAS and XBMC media center) and windows on my work
[12:22:15] <IchGuckLive> no Corel is windows GIMP is Linux
[12:22:28] <Dolence> I'm supposed to be a linux xiita?
[12:22:30] <IchGuckLive> Gimp is also on Windows available
[12:22:41] <Dolence> yeah, but i'm used to corel
[12:22:54] <IchGuckLive> Try Qcad
[12:23:02] <IchGuckLive> or Librecad
[12:23:10] <Connor> and for CAMing use CamBam.
[12:23:13] <ktchk> corel in linux is inkscape
[12:23:14] <IchGuckLive> You will be impressed
[12:23:16] <Dolence> i dotn like to use gimp, i'm not saying its bad, i'm just used to photoshop and corel
[12:23:35] <Dolence> ok, let me explain the scenario
[12:23:37] <Connor> CamBam is Windows, but can be used in a virtual machine.
[12:23:38] <IchGuckLive> ktchk: O.O B)
[12:24:18] <Dolence> a friend of mine give a cnc router to us (whats the difference between mill and router?)
[12:24:40] <IchGuckLive> Dolence: http://www.youtube.com/watch?v=b72n-3T5klA
[12:24:40] <Dolence> but it was using an old Pentiun 233 with dos software
[12:24:48] <ktchk> IchGuckLive: yes ?
[12:25:03] <IchGuckLive> ktchk: you got it wright
[12:25:18] <Dolence> I saw linuxcnc and it's seens to be a nice replacement to modernize my machine
[12:25:54] <IchGuckLive> Dolence: o for linuxman
[12:25:59] <Dolence> so, I installed it on a new computer + elo touchscreen lcd
[12:26:23] <Dolence> so far, so good
[12:26:39] <IchGuckLive> Now you got the 2OS system
[12:26:56] <Connor> Dolence: Use whatever you want o make you dxf/dwg file. Load into CamBam and convert to g-code. It's kinda like a CAD program.. but lets you specify machine operations.. then save out g-code file and take to cnc router.
[12:26:57] <Dolence> Connor ty very much
[12:26:58] <IchGuckLive> so Why if i Stay CADCAM Windows i use Windows CNC
[12:27:19] <syyl> because mach3 is crap?
[12:27:25] <jdh> because mach3 is not as good as linuxcnc, while windows cam stuff is much better than on linux?
[12:27:39] <Dolence> we are using windows on our 2 desktop computers, linux only on cnc dedicated coputer
[12:27:40] <IchGuckLive> syyl agree but for simple things ok
[12:28:02] <Connor> Yup. I use Inventor for CAD, CamBam for CAM and LinuxCNC for the controller.
[12:28:25] <Dolence> autodesk inventor?
[12:28:26] <IchGuckLive> is Cambam only for windows Connor
[12:28:28] <Connor> forget about thinking of the CNC machine as a OS. It's a controller.. There for, I don't load any CAM/CAD packages on it.
[12:28:35] <Connor> Dolence: Yes.
[12:28:38] <archivist> insiderearofskull for cam no need for windows
[12:28:52] <syyl> you dont run a cad/cam system on your siemens or fanuc controll either, dont you?
[12:29:07] <Dolence> if i had one, no
[12:29:09] <Dolence> lol
[12:29:11] <syyl> at least, i dont ;)
[12:29:25] <IchGuckLive> we all do most 2 Systems
[12:29:27] <Dolence> ok, now i get it
[12:29:31] * skunkworks surfs and plays youtube videos on the K&T
[12:29:38] <Dolence> lol
[12:29:51] <syyl> that machine is big enough to live in/on it..
[12:29:52] <syyl> ;)
[12:29:58] <skunkworks> while machining
[12:30:07] <Dolence> my machine is pretty simple and small
[12:30:20] <IchGuckLive> skunkworks: i uploded today 2 more on modifikation the Post to your own nedds on Heekscad
[12:30:38] <Dolence> 100 cm x 60 cm +- workiing area
[12:30:51] <IchGuckLive> Nice Size
[12:30:55] <Connor> Dolence: Use your workstation to CAD and CAM.. Then Sneaker net via Thumb drive or setup a file share so your CNC control machine can access the file and life is good. :)
[12:31:30] <IchGuckLive> <- agrees to connor
[12:31:56] <Connor> Besides, I wouldn't even try to CAD or CAM on the CNC machine... It's just a Atom.. Not much power to run those kinds of things.
[12:32:03] <IchGuckLive> Dolence: what is the main goal Wood Carbon ?
[12:32:15] <Connor> Though, It does suck to have to run into the office from the shop to make a small change to something..
[12:32:28] <skunkworks> I really should play with heeks
[12:32:42] <syyl> heekscam?
[12:32:48] <skunkworks> right
[12:32:49] <Connor> I've found myself editing the gcode file on the CNC to change stuff like spindle speed, or clearance heights etc..
[12:32:51] <IchGuckLive> heekscnc
[12:33:04] <syyl> last time i tried it, it was like putting little needles under my fingernails..
[12:33:15] <ktchk> IchGuckLive: heekscad in github is changing do you knonw when will be the new version comeing?
[12:33:28] <syyl> (in other terms, "not to happy with it")
[12:33:32] <skunkworks> right now - most of my flow is Autocad -> Ace converter -> edit gcode
[12:33:42] <Dolence> omg, you guys talk a lot
[12:33:42] <IchGuckLive> we got problems with the 22 version to get it on linux
[12:34:01] <jdh> most of mine is draftsight->cut2d->linuxcnc, no editing required
[12:34:04] <Dolence> IchGuckLive main goal is cutting plastic/mdf
[12:34:33] <IchGuckLive> Dolence: engraving or real 3D milling
[12:34:34] <Dolence> PEAD / MDF / BRASS
[12:34:45] <Dolence> real 3 d milling
[12:34:52] <IchGuckLive> ok
[12:35:12] <Connor> 3D or 2.5D ?
[12:35:16] <IchGuckLive> Dolence: did you look onto my videos
[12:35:27] <Connor> Big diff.
[12:35:44] <IchGuckLive> Dolence: its only a workflow
[12:36:05] <Dolence> i am looking at it right now
[12:36:14] <Dolence> doing lots of things at same time, phew!
[12:36:26] <Dolence> i am taking a pic of my machine to show
[12:36:32] <Dolence> just a sec, hold on
[12:36:33] <IchGuckLive> Dolence: we will answer 24/7 you needs
[12:37:03] <IchGuckLive> Dolence: The mashine is not the prob the DXF is better
[12:37:49] <Dolence> ty very much, I really appreciate all your support guys
[12:38:10] <IchGuckLive> Thats Why the Channel is here B)
[12:38:11] <ktchk> IchGuckLive:heekscad in github is changing do you knonw when will be the new version comeing?
[12:38:24] <IchGuckLive> 21 is out to CNC
[12:38:35] <ktchk> 21?
[12:38:36] <IchGuckLive> 22 main is not working on ubuntu
[12:39:10] <IchGuckLive> we try to fix this but DAN is of to the USA for 3weeks
[12:39:11] <ktchk> github ?
[12:39:20] <IchGuckLive> yes github
[12:39:34] <ktchk> thanks
[12:39:54] <IchGuckLive> the changes are all to REPRAP
[12:40:15] <ktchk> what about zigzag and waterline
[12:40:30] <IchGuckLive> working since 18
[12:40:50] <ktchk> no they took them off
[12:41:38] <Dolence> IchGuckLive https://dl.dropbox.com/u/80978089/rotul2.dxf
[12:42:12] <ktchk> counterbore lso
[12:42:31] <IchGuckLive> http://www.youtube.com/watch?v=A3m5Liw8LVY ktchk From this week
[12:45:31] <ktchk> IchGuckLive: Yesterday I gitclone heekscad heekscnc complied it and found them missing
[12:46:55] <IchGuckLive> the icons ?
[12:47:06] <IchGuckLive> there are in the mashine Menue
[12:47:47] <ktchk> let me bootup the new machine
[12:48:11] <IchGuckLive> Dolence: there are 4 layers in BAD
[12:49:34] <Dolence> in the past, the guy who was making the cuts was correcting this small things to me, now I will have to learn
[12:50:18] <IchGuckLive> i got it
[12:53:43] <Dolence> now I feel the lack of fluence in english
[12:54:20] <IchGuckLive> its good ewnoph
[12:56:04] <IchGuckLive> Dolence: hat currr
[12:56:21] <IchGuckLive> and CRC in use or only outline fix ofset
[12:58:14] <Dolence> hat currr?
[12:59:03] <IchGuckLive> CRC means the mashie can correct the offset G$!/42 you need to set the Toldiameter your own
[12:59:15] <IchGuckLive> G41
[12:59:43] <IchGuckLive> Fix means you got a 5mm cutter and we say mill at a 2.5mm distance to the part
[13:01:47] <Dolence> ok
[13:03:57] <Dolence> I'm on final stage of redoing eletric wiring and so, after that I will put the machine to work :D
[13:04:12] <Dolence> thank you very much IchGuckLive, thanks you guys!
[13:04:29] <Dolence> now i just need some practice :D
[13:05:21] <IchGuckLive> is this for lasercut
[13:05:45] <Dolence> not laser
[13:07:44] <ktchk> IchGuckLive: I confirm that zigzag waterline and counterbore was out
[13:09:14] <IchGuckLive> ktchk: the icon or in mashine menue
[13:09:22] <ktchk> both
[13:12:15] <IchGuckLive> in 3D operation no waterline
[13:12:57] <ktchk> my old heekscnc 0.18 have waterline
[13:15:29] <Dolence> whats the diff between milling x routing?
[13:15:40] <Dolence> milling machine and routing machine? seens the same to me...
[13:16:25] <IchGuckLive> milling is a better then a router
[13:16:38] <IchGuckLive> Milling are most Servos router steppers
[13:16:52] <jdh> routers are better if you need routing
[13:16:59] <IchGuckLive> ktchk: i got the last now compiled and its there
[13:17:11] <ktchk> when
[13:17:28] <ktchk> now?
[13:17:29] <jdh> servo/stepper has nothing to do with being a mill or a router
[13:19:12] <Dolence> my machine have a stationary tool, and table moves
[13:19:24] <Dolence> 3 axis
[13:20:00] <Dolence> I'm not sure if it's a mill or router
[13:20:13] <jdh> what would you like to call it.
[13:20:34] <Dolence> just machine is ok?
[13:20:57] <Dolence> HAL is a good one too
[13:20:58] <jdh> You could call it Carmen.
[13:21:11] <IchGuckLive> ktchk: http://mechmo.de/heeks_21.png
[13:21:11] <Dolence> no, for god sake, Carmen no!
[13:21:40] <Dolence> Carmen = too much headache
[13:21:48] <Dolence> to me
[13:21:50] <Dolence> at least
[13:22:25] <IchGuckLive> ktchk: its not a plecent to get a menue shot
[13:23:21] <IchGuckLive> Dolence: are this circles not holes they are sqate in shape
[13:24:04] <Dolence> they are suposed to be holes
[13:25:15] <IchGuckLive> THIS is Realy bad CAD if never seen sutch miss n my live on CADCAM as i work now 35 Years on
[13:26:35] <Dolence> hahahahaha
[13:27:25] <IchGuckLive> ther are mainly 3-4 overlays on etch line
[13:27:31] <IchGuckLive> same layer
[13:27:41] <Dolence> we are just 2 hobbists, I'm really sorry for that
[13:28:09] <IchGuckLive> let me try a powerscript
[13:29:35] <IchGuckLive> ktchk: the 18 works perfect no change needet as REPrap only
[13:29:50] <Dolence> is reprap that 3d printer?
[13:30:48] <IchGuckLive> yes
[13:32:56] <Dolence> looks awesome
[13:33:06] <IchGuckLive> What
[13:33:12] <Dolence> reprap
[13:33:31] <Dolence> seens to be so cool
[13:44:17] <IchGuckLive> Dolence: no the masterscript coudt not handle the file proper
[13:48:11] <Dolence> IchGuckLive np, ty anyway, i will do some experiments later
[13:48:15] <Dolence> ty IchGuckLive
[13:57:48] <IchGuckLive> Dolence: i mayd it
[14:00:35] <IchGuckLive> Dolence: your cutter 5mm ?
[14:02:22] <r00t4rd3d> http://www.kickstarter.com/projects/paulstoffregen/teensy-30-32-bit-arm-cortex-m4-usable-in-arduino-a
[14:02:30] <r00t4rd3d> Teensy 3.0
[14:03:51] <r00t4rd3d> i wonder how well that would work with CNC
[14:07:01] <r00t4rd3d> jepler
[14:07:14] <IchGuckLive> Dolence: still here ?
[14:08:25] <Dolence> yes
[14:08:28] <Dolence> i'am here
[14:08:44] <IchGuckLive> i will do a screenshot
[14:08:46] <Dolence> IchGuckLive you build a reprap ou you designed it?
[14:08:53] <Dolence> ok
[14:09:55] <IchGuckLive> im no 3D
[14:10:12] <IchGuckLive> your DXF to G-code
[14:10:51] <IchGuckLive> http://mechmo.de/dolence_g.png
[14:11:34] <Dolence> you did it on heekscad?
[14:11:40] <IchGuckLive> yes
[14:11:44] <Dolence> not cambam needed?
[14:11:46] <Dolence> *no
[14:12:00] <IchGuckLive> does cambam work on linux ?
[14:12:21] <Dolence> i dont think so lol
[14:12:50] <IchGuckLive> The Text is very little so no milling at 3mm
[14:13:12] <IchGuckLive> also ther needed to be set drillpoints to the holes
[14:13:56] <IchGuckLive> Dolence: if you zoom in you can see that up left part is a miss in the Linup of the sketch
[14:15:40] <Dolence> I see...
[14:15:46] <Dolence> i will try it
[14:16:13] <IchGuckLive> this you can easy fix in librecad or qcad
[14:16:33] <IchGuckLive> just order them new by aligning them in one way
[14:18:10] <Dolence> IchGuckLive what you think, should I do all the drawing direct on cad software and skip corel?
[14:18:33] <IchGuckLive> YES ofcause
[14:19:51] <Dolence> ok
[14:20:12] <IchGuckLive> The miss i woudt fix at Linuxcnc its mutch easyer as there are full circel turns
[14:20:28] <IchGuckLive> that coud get out by editor
[14:23:12] <IchGuckLive> Dolence: Querry
[15:25:07] <Connor> What's the best way to setup round stock to cross drill holes? I need to drill/tap holes in the pulleys...
[15:25:49] <Connor> I wish I could mount my freaking 4" chuck to my rotary table..
[15:31:23] <mrsun> hold it in a vice? :P
[16:48:17] <Jymmm> http://cdn.memegenerator.net/instances/400x/22605665.jpg
[16:48:21] <DJ9DJ> gn8
[16:50:00] <Connor> Okay, so, what the heck is the trick to getting a 4" chuck off of a R8 Arbor? It had 3 bolts on the back that I removed.. and I can't get it off.. Or, are they suppose to come off after being mated?
[16:50:24] <Tom_itx> put the pulley in a vise
[16:50:27] <Tom_itx> measure the diameter
[16:50:34] <Tom_itx> move the cnc over half that
[16:50:37] <Tom_itx> drill a hole
[16:51:11] <Tom_itx> leave the arbor on it
[16:51:48] <Connor> Kinda hard to use the chuck on the rotary table if it's on the arbor..
[16:52:23] <Tom_itx> mark it before you separate it
[16:52:50] <Connor> I did.
[16:52:58] <Connor> with a sharpie.
[16:53:05] <Connor> but, I can't get it apart.
[16:53:08] <Tom_itx> that's not very permanenet
[16:53:13] <Tom_itx> oil will remove that
[16:53:50] <Connor> Marking isn't going to do me any good if I can't get it apart.
[17:38:27] <Dolence> hi!
[17:38:49] <Dolence> guys, I managed to made all wirings to my cnc machine
[17:39:01] <Dolence> now i am trying to define homes
[17:40:01] <Dolence> but when i click on home x, or y, or even z, the machine moves to the wrong direction
[17:40:03] <r00t4rd3d> why is a motorcycle called a "motor"cycle, shouldnt it be called an enginecycle?
[17:40:23] <Tom_itx> Dolence reverse them
[17:40:33] <r00t4rd3d> motors are electric, engines are gas.
[17:40:36] <Tom_itx> what's your scale?
[17:40:59] <Dolence> change the switches position or can I do it on software?
[17:41:43] <Tom_itx> it's easier to fix in software probably
[17:42:06] <Dolence> i dont have idea on how to do it... could you please tell me?
[17:42:12] <jdh> what do you do with motor oil?
[17:42:17] <Dolence> (if you know how to do that)
[17:42:36] <atom1> i asked you what your SCALE was
[17:42:42] <atom1> make that a negative
[17:42:42] <Dolence> mine?
[17:42:44] <atom1> and try it
[17:42:56] <atom1> that will reverse direction
[17:43:46] <Dolence> i will try it
[17:43:52] <Dolence> and report back
[17:43:55] <Dolence> thanks ;)
[17:43:56] <Tom_itx> steppers?
[17:44:03] <Dolence> yeah
[17:44:07] <Tom_itx> try that
[17:44:33] <Tom_itx> do you have home/ limit switches?
[17:44:50] <Tom_itx> make sure they're working as expected too
[17:45:23] <Dolence> yes, i have... a friend of mine give this machine to me, and all switches was disconnected
[17:45:34] <Dolence> i am trying to figure out on how to get all of them working
[17:49:19] <JT-Shop> Dolence: you have home switches?
[17:49:49] <JT-Shop> is this a Stepconf Wizard generated configuration?
[17:54:26] * JT-Shop goes outside to play
[17:54:49] <Dolence> Tom_itx
[17:54:52] <Dolence> that worked!
[17:54:54] <Dolence> ty man
[17:55:18] <Dolence> do you know whats the meaning of "joint 0 on limit switch error" ?
[17:56:37] <jdh> your first axis is either on the limit switch, or the logic is inverted.
[17:58:22] <Tom_itx> yeah you need to set up your limit switches next
[17:58:25] <Dolence> when I do a home scan, tjhe limit is being activaded
[17:58:35] <Tom_itx> or disable them
[17:58:48] <Dolence> hmmm, I already had limit pins setted on wizard
[18:02:32] <Tom_itx> look at NO_FORCE_HOMING in the [TRAJ] section
[18:02:59] <Dolence> ok
[18:03:24] <Tom_itx> also HOME_SEQUENCE
[18:03:31] <Tom_itx> you want z to go first usually
[18:05:01] <Dolence> there is no NO_FORCE_HOMING on my [TRAJ] section, should i add it?
[18:05:13] <Tom_itx> read about it first
[18:05:19] <Tom_itx> i think you can disable them there
[18:05:32] <Tom_itx> temporarily
[18:08:34] <Jymmm> big ass thnder!
[18:08:52] <Dolence> I think it's not exactly what I need
[18:09:11] <Tom_itx> no but it may help you on the way
[18:09:14] <Dolence> I could disable limits
[18:09:23] <Tom_itx> the logic on your limits may need reversed too
[18:09:42] <Dolence> i dont understand it
[18:09:56] <Tom_itx> what don't you understand?
[18:10:56] <Dolence> its expected to reach home before limits, right?
[18:11:36] <Tom_itx> i'll post my config files
[18:11:52] <Tom_itx> i use one switch for both
[18:12:05] <Dolence> ok
[18:12:11] <Tom_itx> and set home .1" off the switch
[18:16:59] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/cnc/configs/sherline/
[18:17:57] <Tom_itx> HOME_IGNORE_LIMITS
[18:18:07] <Tom_itx> you may need that if you're using the same switch
[18:36:48] <Dolence> i am not using the same switch
[18:36:57] <Dolence> i am using same switch for all limits
[18:37:05] <Dolence> ops
[18:37:26] <Dolence> i am using same pin for all limit switches and individual pisn for home
[18:37:46] <Dolence> 3 limits switches and 3 home switches
[19:33:29] <r00t4rd3d> should my plunge rate be half of my ipm rate?
[19:34:27] <r00t4rd3d> i thinks that what i read somewhere and what i currently do
[19:41:26] <Tom_itx> good place to start, yes
[19:41:37] <Tom_itx> ramp or plunge?
[19:41:54] <Tom_itx> i don't like either unless it's unavoidable
[19:44:32] <r00t4rd3d> plunge, right now it just goes straight down in to the wood
[19:44:42] <r00t4rd3d> what should i be doing?
[19:46:30] <Tom_itx> in wood it likely won't matter
[19:46:46] <r00t4rd3d> the only options i only have ramp options besides plunge
[19:46:54] <r00t4rd3d> -only
[19:46:59] <Tom_itx> if i'm cutting into a closed pocket, i like to ramp in if possible
[19:47:08] <Tom_itx> or predrill a hole and plunge into it
[19:47:17] <Tom_itx> but that's not so efficient
[19:47:42] <Tom_itx> so hand edit it
[19:48:14] <r00t4rd3d> i mainly use carbide bits that are made for plunge cuts
[19:48:32] <r00t4rd3d> they got the teeth on the bottom
[19:49:13] <r00t4rd3d> my ipm is 12 so waiting for 6 sucks
[19:50:02] <r00t4rd3d> i need a new controller
[19:50:08] <r00t4rd3d> 12 sucks too
[19:51:27] <Tom_itx> won't go faster than 12?
[19:51:41] <r00t4rd3d> nope
[19:51:58] <Tom_itx> well you can probably plunge at that rate or ramp
[19:52:29] <r00t4rd3d> i use threaded rod from the hardware store for 2 of my lead screws, i dont think that helps my speed much either
[19:54:54] <r00t4rd3d> if i turn up the velocity, my motors just make weird noises
[19:55:34] <r00t4rd3d> its at 0.2 atm
[19:55:40] <Tom_itx> get some good drivers
[19:55:45] <Tom_itx> makes all the difference
[19:56:11] <Tom_itx> i did that and increased the motor voltage by double
[19:56:24] <r00t4rd3d> i have a good supply too
[19:56:37] <Tom_itx> i got 50v going to my drivers
[19:56:59] <r00t4rd3d> mine is 24v but i have it turned down to 18
[19:57:14] <Tom_itx> you saw mine didn't you?
[19:57:21] <r00t4rd3d> ur power yeah
[19:57:28] <Tom_itx> in action
[19:57:45] <r00t4rd3d> cant remember but i know ive seen it
[19:58:30] <r00t4rd3d> Rated Voltage: 3V
[19:58:30] <r00t4rd3d> Rated Current: 2A/Phase
[19:58:35] <Tom_itx> http://www.youtube.com/watch?v=XhU7S8kifJ4&feature=youtu.be
[19:59:42] <Tom_itx> mine run cooler now than they ever did
[20:00:03] <r00t4rd3d> i know my limit is the tb6560
[20:00:10] <r00t4rd3d> my bottleneck
[20:01:35] <Tom_itx> but performance costs
[20:07:38] <Sub-> well, there's a room on freenode for everything it seems
[20:08:06] <Connor> Tom_itx: What kind of mill is that ?
[20:08:19] <Tom_itx> sherline
[20:09:33] <Tom_itx> there's one actally cutting something: http://www.youtube.com/watch?v=-CEqokrtFI4&feature=youtu.be
[20:10:12] <FinboySlick> Tom_itx: Wow, that runs terribly smooth for a sherline... Did you do anything to the ways?
[20:10:27] <Tom_itx> no just adjusted stuff
[20:10:40] <Tom_itx> added a counterweight to z to offset the motor
[20:10:49] <FinboySlick> I have a non-CNC version of that mill.
[20:10:55] <FinboySlick> It needs lots of TLC.
[20:11:03] <Tom_itx> time to add some motors to it
[20:15:01] <FinboySlick> Hmmm, while I see you milling plastic... Is a fast spindle better or worse for nylon? I have a project that I plan to mill with a 1/8 2flute and I can't really spin below 8kRPM.
[20:15:43] <Tom_itx> it'll burn if you go too slow probably
[20:15:48] <Sub-> would someone confirm the linuxcnc set up for me please? I'd like to be sure I understand properly (very new at this)… I have a modest pc running linuxcnc, this connects via a parallel port/cable to something like a geckodrive controller unit (please shout up if there is a better choice for a new guy), and my steppers connect to the gecko. Is this right? I assume I need a PSU, do I run power directly into the gecko type controller unit f
[20:15:48] <Sub-> the steppers?
[20:15:50] <Tom_itx> kick up the feedrate
[20:16:04] <FinboySlick> That'll be scary :P But the mill can move fast.
[20:16:21] <FinboySlick> I guess I should look for a specific chipload and stick to it.
[20:16:23] <Tom_itx> sub, yes pretty much
[20:16:34] <Tom_itx> yeah
[20:16:40] <Tom_itx> i got a reference here...
[20:17:08] <Tom_itx> http://www.onsrud.com/plusdocs/Doc/index.html?model.code=FeedSpeeds
[20:17:14] <Sub-> Tom_itx: thankyou. What about first positioning reference, do i connect some limit microswitches into the gecko for a start up calibration?
[20:17:49] <Tom_itx> i used a pair of mesa cards between my parport and the gecko drives
[20:17:55] <Tom_itx> makes life nicer
[20:18:25] <Sub-> mesa cards eh, no idea what they are /me googles
[20:18:39] <FinboySlick> Tom_itx: Thanks, that'll help. I was going to see if CNC Cookbook could help but I might have to budget for it, my trial expired.
[20:18:43] <Tom_itx> http://www.mesanet.com/
[20:19:11] <Tom_itx> FinboySlick, i added a couple more links at the top here: http://tom-itx.dyndns.org:81/~webpage/cnc/psu/psu_index.php
[20:19:18] <Tom_itx> for lack of a better place to put htem
[20:20:00] <Tom_itx> Sub-, i'm using the 7i43 and 7i47 but the 5i25 would be a nice card for a pci buss
[20:20:02] <jp__> PCW must be happy with all of us mesa lovers!!!
[20:20:18] <Sub-> Tom_itx: ty, reading now
[20:20:21] <Tom_itx> most of their business is commercial i bet
[20:20:43] <PCW> Yeah but the LinuxCNC stuff is more fun
[20:20:45] <Tom_itx> Sub-, look under anything io cards
[20:20:49] <Tom_itx> and daughter cards
[20:21:05] <Sub-> yep, got it
[20:21:06] <Tom_itx> or just bug the crap outta PCW and make him earn his keep
[20:21:45] <PCW> :-)
[20:26:04] <Sub-> im interested in using linuxcnc for a lightweight delta robot, so don't need milling type torques and will be using low current nema 17 steppers. These run fine in my RepRap on the cheap Pololu stepper drivers, can I use that sort of set up initially with linuxcnc?
[20:26:23] <Tom_itx> probably
[20:26:38] <Tom_itx> you gonna print with it?
[20:26:58] <Tom_itx> did you make a roStock?
[20:27:20] <Sub-> no, use it as a base to develop a computer vision system… i want it to be able to "see" it's workspace, then identify and classify objects and pick up/sort them
[20:27:32] <Sub-> rostock looks AWESOME doesn't it :)
[20:27:33] <Tom_itx> nice
[20:27:37] <Tom_itx> yes
[20:27:50] <Tom_itx> bak in a while..
[20:28:04] <Tom_itx> mama want's icecream
[20:30:04] <Sub-> Ben & Jerry's Peanut Butter Cup
[20:32:18] <skunkworks__> Sub-: http://www.youtube.com/watch?v=5MOSnFSx8JQ
[20:32:51] <Sub-> skunkworks__: I know! I seen that, it looks awesome
[20:33:01] <Sub-> apparently he's a helpful guy, yhe uploader
[20:33:08] <Sub-> but i don't know him and didn't want to bother him
[20:34:04] <Sub-> looks like he homebrewed his driver boards
[20:34:06] <Sub-> impressive
[20:34:15] <skunkworks__> pretty cool
[20:34:20] <Sub-> indeed
[20:35:59] <jp__> thats awesome!!!
[20:37:48] <Sub-> i printed/built a quick delta prototype to play with, I'm ready now to more to something a bit more substantial though: http://imgur.com/a/cnN1i
[20:38:10] <Sub-> the cheap hobby servos have poor resolution
[20:40:01] * skunkworks__ wants to make a hexapod some day
[20:40:11] <Sub-> yeah, they look fun
[20:40:49] <jp__> man i need to get my printer working too much cool stuff too print!!
[20:40:57] <FinboySlick> Sub-: That looks like some pretty good 3d printing quality, is that a reprap?
[20:41:01] <Sub-> what kind you got jp?
[20:41:11] <jp__> my own design
[20:41:14] <Sub-> FinboySlick: yeah, it's a little reprap huxley
[20:41:32] <Sub-> jp__: roll your own 3d printer huh, you clever clogs ;)
[20:43:17] <jp__> guess i could of just slapped an extruder to my mill!!
[20:43:31] <jp__> that would of been eaiser
[20:43:52] <FinboySlick> jp__: Now that's a great idea.
[20:44:03] <Sub-> mill probably moves a lot slower than is ideal for aprinter?
[20:44:11] <Sub-> should work though
[20:44:36] <jp__> my kit VMC moves pretty dam fast
[20:44:41] <FinboySlick> Sub-: Mine moves fast enough but it's probably going to be wasting quite a bit of energy in the process.
[20:45:13] <Sub-> yeah
[20:45:17] <FinboySlick> It'll probably go through the floor too.
[20:45:25] <jp__> Thats why i did not kkinda a pita to fire up the phase converter just to run a print
[20:45:27] * FinboySlick needs to strengthen it.
[20:45:55] <Sub-> the new prusa i3 is due before long
[20:45:59] <Sub-> that looks good
[20:46:33] <jp__> Tried to cut a nozzle with a laser today
[20:46:44] <jp__> need more power
[20:46:44] <Sub-> ?
[20:46:54] <jp__> the orfice
[20:47:15] <Sub-> i'd imagine anything you can laser cut isn't suitable for a nozzle? surely it would soften/melt at extrusion temperatures
[20:47:20] <FinboySlick> jp__: edm and a needle?
[20:47:41] <jp__> good idea
[20:47:54] <jp__> 30 wat yag on alum sucked
[20:48:05] <Valen> you can laser steel ok
[20:48:14] <Valen> Al is going to be too reflective
[20:49:03] <Valen> well you heat it with the laser, then the air blows the hot steel out of the way/burns it with O2
[20:49:04] <jp__> i tested it out on steel and then went ahead and machined my blanks out of alum
[20:49:13] <FinboySlick> I know that you can color metals with a laser. I wonder if it would be energy efficient to darken, blast, darken, blast.
[20:49:35] <Valen> they colour it with a moly-sulphide powder
[20:49:47] <Valen> it really just changes the chemical composition at the surface
[20:49:54] <Valen> well for steel etching anyway
[20:50:14] <Valen> for Al they anodise it and the laser kills the dye selectivly
[20:50:37] <FinboySlick> What I read was on aluminium... They apparently created the blackest black that way. (Cue Dethclock)
[20:51:11] <FinboySlick> I'm pretty sure it was just modulating temperature but I'm not sure.
[20:51:11] <Valen> yeah, surface treatment only though and with advanced magic to boot
[20:51:14] <jp__> different wavelength probably
[20:52:21] <ScribbleJ> When I cut acrylic with my laser it leaves behind this sticky smelly acrylic resin I guess.
[20:52:49] <jp__> That happens with my sawzall too!! lol
[20:53:15] <ScribbleJ> Is it a laser sawzall?!
[20:53:17] <ScribbleJ> Awesome!
[20:53:20] <ScribbleJ> heh
[20:54:26] <FinboySlick> http://www.youtube.com/watch?feature=player_detailpage&v=rgMf2Go-qCE#t=25s
[20:54:40] <FinboySlick> "Blacker than the blackest black... times infinity."
[20:54:44] <L84Supper> FinboySlick, which blackest black was this that you read about?
[20:55:03] <L84Supper> I type too slow :)
[20:55:28] <FinboySlick> L84Supper: Hehe... Seriously, it was an article on Slashdot years ago.
[20:57:01] <FinboySlick> I just remember it because I was thinking: Superblack on aluminium: Solar heating.
[20:57:16] <FinboySlick> But I'm Canadian so it's moot.
[20:58:11] <jp__> FinboySlick: Where abouts?
[20:58:34] <FinboySlick> jp__: Eastern Quebec. Gaspe peninsula.
[20:59:05] <jp__> ah quite the scene yesterday eh!!
[20:59:56] <FinboySlick> jp__: I'm just glad we've got a minority government. The less these jerks can do the better off we are.
[21:00:11] <FinboySlick> And I consider that valid for all parties.
[21:00:44] <jp__> Im in Ontario with a minority as well but different jerks
[21:05:19] <Valen> you can still do solar heating even if its cold
[21:05:39] <Valen> hide your heat soakeruper behind some glass insulation
[21:06:21] <FinboySlick> Valen: I know, I was just being stereotypical :)
[21:06:54] <Sub-> heat soakeruper, that's a technical term, is it? ;)
[21:06:59] <Valen> i think do
[21:07:02] <Valen> so
[21:07:06] * Sub- nods
[21:07:12] <Valen> i am a rocket scientist, so it damn well is now!Q
[21:07:20] <Valen> ffs i'm having an awesome day for typing
[21:07:35] <L84Supper> absorberer has been depreciated
[21:09:26] <jp__> is the wiki down or is it just me?
[21:11:17] <L84Supper> it pings, traceroutes and loads here, after a short delay
[21:11:28] <Valen> which wiki?
[21:11:31] <jp__> ah got it
[21:11:43] <L84Supper> wiki.linuxcnc.org at least this does
[21:11:50] <jp__> linuxcnc of course
[21:12:16] <Valen> works fine for me
[21:13:44] <tjb1> Best all purpose tap would be a plug?
[21:14:10] <Tom_itx> depends on the purpose :)
[21:14:26] <tjb1> all ;)
[21:14:37] <FinboySlick> tjb1: tap as in threads?
[21:14:53] <tjb1> yessum
[21:15:06] <Sub-> you dont' want a plug
[21:15:08] <Tom_itx> spiral point tends to shove the shavings out the hole
[21:15:11] <Sub-> plug is for bottoming
[21:15:20] <Tom_itx> a bottoming tap isn't good for starting threads
[21:15:25] <Sub-> exactly
[21:15:36] <tjb1> No sub, a bottoming is for bottoming
[21:15:39] <Tom_itx> a spiral flute tap would be better for production
[21:15:53] <Sub-> same thing, we call a plug a bottoming tap
[21:16:00] <tjb1> its not the same thing
[21:16:10] <tjb1> bottoming have almost no taper at all
[21:16:16] <Tom_itx> then the answer is no
[21:16:41] <FinboySlick> tjb1: If you don't have to go deep, or fast, SPTM is an interesting approach too.
[21:17:05] <tjb1> This is a hand jobber ;)
[21:17:23] <Sub-> tjb1: i stand corrected
[21:17:26] <FinboySlick> It's starting to sound dirty.
[21:17:29] <Valen> mill the damn threads
[21:20:07] <uw> has anybody built a laser cutting machine?
[21:20:15] <uw> anybody here rather
[21:20:33] <Valen> any paticular reason?
[21:20:47] <uw> i would like to build one and get an idea of costs
[21:20:58] <uw> mostly the laser parts
[21:21:04] <jp__> co2?
[21:21:34] <uw> that or i was reading UV lasers are a bit finer.
[21:21:56] <uw> but really, that's also some of the advice I'd be looking for
[21:21:57] <Valen> what is the end use of it?
[21:22:29] <uw> I'd like to cut plastic and wood 1/4" thick
[21:22:39] <jp__> you can get cheap co2 kits
[21:22:57] <jp__> for that kind of stuff
[21:23:08] <uw> well, any recommendations for a cheap co2 kit that wont break in 2 weeks?
[21:23:19] <jp__> but they are bulky
[21:23:46] <jp__> no
[21:25:55] <Valen> laser and plastic is often a bad combo
[21:26:14] <Valen> gives off nasty fumes
[21:27:54] <jp__> imagine PFTE!!
[21:28:02] <jp__> ouch
[21:28:25] <Valen> rather
[21:28:35] <tjb1> Well ordered the stupid reamer...
[21:28:39] <Valen> i think the only plastic people are generally happy lasering is acrylic
[21:28:41] <tjb1> and the tap since my school has nothing metric
[21:28:41] <Valen> and its shit lol
[21:28:50] <jp__> most engraving shops use laser to cut lamicoids
[21:29:25] <jp__> most around these parts anyways
[21:29:41] <L84Supper> http://misspiggy.gsfc.nasa.gov/tva/issfoc/iss/docs/HenningFEP.doc thermal decomposition of PTFE
[21:29:56] <tjb1> <3 amazon prime and amazon supply
[21:30:15] <tjb1> Oh someone here doesnt like amazon supply, who lost stuff?
[21:32:43] <Valen> I can see the upside to laser over milling though
[21:32:55] <Valen> no need to worry about holding parts and the like
[21:33:21] <jp__> did you see that you tube vid of the sls and 5 axis mill in one?
[21:34:19] <Valen> no?
[21:35:11] <jp__> http://www.youtube.com/watch?v=CsEqKbNalh4
[21:37:06] <Valen> whats the point?
[21:37:56] <L84Supper> fewer machines, faster
[21:39:13] <jp__> Additive vs billet or forging or casting
[21:41:15] <Valen> i mean if you are additive then why machine
[21:41:58] <jp__> form probably
[21:42:10] <L84Supper> the SLS is much lower precision than the milling, by having them in the same machine you can machine each layer
[21:42:48] <L84Supper> well, their method of SLS
[21:43:23] <Valen> you could make the sls better ;->
[21:59:40] <uw> Valen, i wouldnt be in the same room when it was working, and run a exhaust fan (if i didnt roll the whole machine outside to cut)
[22:00:28] <Valen> i mean polcarb makes cyanide gas
[22:00:33] <Valen> polycarb
[22:00:42] <Valen> heating organics is a bad plan
[22:02:45] <uw> you can also get hit by a car while crossing the street
[22:03:28] <Tom_itx> so you have been warned about both now
[22:08:25] <Valen> I'm happy to be around lots of chemicals, but cyanide is a nono
[22:08:29] <Valen> anything with chlorine in it
[22:10:42] <Aero-Tec> can one mirror a part easy?
[22:10:57] <Aero-Tec> like scale -1?
[22:11:20] <Tom_itx> some machines will mirror a cutter path but it also reverses the cut direction
[22:11:22] <Valen> thats generally something one would do in the CAM
[22:11:26] <Aero-Tec> is there any scale option in EMC
[22:11:29] <Tom_itx> ie if it was conventional it will climb
[22:11:44] <Tom_itx> it's not always a good idea
[22:11:58] <Tom_itx> i'd rather fix the paths in a cad cam first
[22:12:17] <Aero-Tec> ok
[22:12:54] <Valen> i wonder if the cord-rotation would do it?
[22:13:01] <Aero-Tec> is there a scale option in EMC?
[22:14:03] <Valen> uhh, kinda but not really
[22:14:09] <Valen> you could change the machine scale
[22:14:16] <Valen> but that sounds like a bad plan
[22:14:22] <Valen> what are you actually trying to do?
[22:14:38] <Aero-Tec> so not like mach where it has a part scale
[22:15:05] <Valen> why would you want to do that?
[22:15:26] <Aero-Tec> cool option
[22:15:34] <Aero-Tec> can be handy
[22:16:50] <Valen> sounds like a hack to make up for other shorcomings ;-P
[22:16:54] <Valen> shortcomings
[23:05:59] <Aero-Tec> it was just a quick and easy way to get a mirror part cut
[23:06:12] <Aero-Tec> did not say it was the best way
[23:17:33] <r00t4rd3d> http://i.imgur.com/UeATk.jpg
[23:17:43] <r00t4rd3d> where does one get a giant foam block like that?
[23:18:35] <r00t4rd3d> make them?
[23:59:16] <Aero-Tec> I see that the examples are all lowercase
[23:59:28] <Aero-Tec> is that how it has to be?
