#linuxcnc | Logs for 2013-08-19

[00:05:34] <WalterN> enh, I would only worry about that if you do a lot of aluminum... plastic is what wants really really sharp toolbits
[00:06:32] <WalterN> CaptHindsight: on a side note, I got my 1/2 watt 405nm laser
[00:58:55] <Loetmichel> mornin'
[02:09:28] <DJ9DJ> moin
[02:09:39] <kengu> what ever
[04:02:43] <kengu> so if I get like mesa 7i43 and 7i42 I should be able to rewire the plasma cutter and then get a linuxcnc understand the hardware if I did my reading right
[04:03:46] <kengu> and still have some extra io in comparision to straight parallel where my io would have been tight fit, maybe lacking input for EStop or likes
[04:04:02] <kengu> and it is not even expensive
[04:05:44] <kengu> but now to post office to figure out what new toys or goodies there is waiting for me
[05:42:50] <Nick001> !latest
[05:43:26] <archivist> there is no latest command
[06:08:20] <Nick001> I know - wrong window
[08:33:56] <CaptHindsight> http://www.mebotics.com/microfactory.html
[08:34:26] <CaptHindsight> "Machine Shop In a Box" a bit of a stretch
[08:34:52] <CaptHindsight> glue gun + router
[08:36:14] <spack> heh
[08:36:42] <spack> i bought a rather large, old bostomatics CaptHindsight
[08:36:49] <spack> wanna help me fit it into a garage? :)
[08:38:25] <archivist> spack rollers and levers, that's how my stuff enters the garage
[08:38:37] <jdh> ever had anything leave?
[08:38:46] <spack> yeah, it's just a matter of gaining 9+" of clearance
[08:40:36] <spack> probably a 93" tall machine and an 84" tall garage door?
[08:40:41] <Tom_itx> any good front loader worth it's weight could gain you all the clearance you need
[08:40:54] <Tom_itx> may need a few repairs afterward
[08:41:07] <archivist> take parts of----push---> put parts back on
[08:41:18] <CaptHindsight> http://www.kickstarter.com/projects/6735955/nrg3-a-3d-printable-assembly-tool
[08:41:34] <skunkworks> well - the brown and sharp is gone.
[08:41:40] <spack> archivist: that's where i wanted CaptHindsight's help :)
[08:41:50] <archivist> is he local?
[08:42:04] <spack> yeah, he's on the opposite side of town though
[08:42:41] <spack> it's a stretch, but i thought he might be bored or something :)
[08:42:45] <CaptHindsight> If I had some free time I would sleep
[08:42:56] <Tom_itx> CaptHindsight, do they need a hot chick to sell it?
[08:43:02] <spack> sleep doesn't offer beer
[08:43:13] <Tom_itx> i got a roller clutch wratchet already and it doesn't work that well
[08:43:25] <Tom_itx> friend gave it to me years ago
[08:44:02] <spack> time to hop on the bike and get to work
[08:44:04] <spack> later
[08:49:58] <archivist> CaptHindsight, not sure if that spanner can possibly have a valid patent!
[08:52:13] <CaptHindsight> archivist: that's the nice thing about the USPTO, you are welcome to spend millions fighting over it in court
[08:53:36] <archivist> but a one way roller clutch has been around for ever !
[09:09:34] <archivist> CaptHindsight, prior art http://www.google.com/patents/US6253646
[09:10:40] <archivist> and an earlier one http://www.google.com/patents/US728900
[09:16:47] <CaptHindsight> yeah, but this one is partially 3D printed :)
[09:17:28] <archivist> iirc how you make something should not be part of the patent
[09:17:39] <CaptHindsight> I wonder if adding 3D printed will make things patent-able the same way it was by adding internet
[09:18:03] <archivist> only in the broken and biased USPTO
[09:20:26] <CaptHindsight> it's the best patent system that money can buy
[09:30:15] <FinboySlick> Patents (and copyrights) should only be about giving credit for the work/innovation. The rest actually does more harm than good.
[09:31:38] <FinboySlick> Even pharma is at the point where they prefer releasing ineffective, harmful drugs they can patent over the ones that work.
[09:33:14] <mozmck> FinboySlick: "Even pharma"??? I think they've been leading the pack for a while.
[09:33:56] <FinboySlick> mozmck: That was from the perspective that they tend to be the ones claiming they need patents because the development costs are so high.
[09:34:26] <cradek> securing exclusive manufacturing/sale of new drugs with patents is the only way anyone can earn back the R&D costs of making new drugs
[09:35:02] <cradek> drug patents are limited to a fairly short time, unlike other more broken types of patents
[09:35:05] <mozmck> yeah. That's because they refuse to even look at simpler more effective natural things, because they can't corner the market on those and make boatloads of money.
[09:36:49] <FinboySlick> cradek: I think the shorter time that was intended as a benefit is also becoming harmful. They're focusing on always getting new patents rather than getting effective medicine.
[09:37:05] <cradek> plenty of other people are making their boatloads of money selling simple/natural things that aren't the same as medicine. it's a different business...
[09:38:02] <cradek> FinboySlick: also I've heard of making minor/insignificant changes to old drugs to get a second patent time span - a loophole that should be removed
[09:38:17] <jdh> claritin vs. clarinex
[09:38:49] <FinboySlick> cradek: Dichloroacetate is a good example of an effective drug that has been fought tooth and nails because it can't be patented.
[09:40:43] <FinboySlick> I don't think we'd stop innovating for lack of patents anyway. We'd innovate because we need to, want to, or simply can.
[09:43:27] <mozmck> I think this is a pretty good article: http://hintjens.com/blog:31
[09:48:56] <Xfriend> hello
[09:49:41] <cradek> hey
[09:50:20] <Xfriend> how is everything ??
[10:54:18] <jdh> 20% off everything at ENCO today. No exclusions.
[11:00:35] <CaptHindsight> http://linuxgizmos.com/controller-adopts-real-time-linux-on-arm-fpga-soc/ I wonder how well these might play with Linuxcnc and Comedi?
[11:07:00] <CaptHindsight> they use RT-PREEMPT on the ZYNQ
[11:09:17] <archivist> is NI changing its spots and playing nice with open source?
[11:09:42] <CaptHindsight> https://decibel.ni.com/content/message/56800#56800
[11:09:49] <archivist> not like them, they like to financially rape the customers :)
[11:14:17] <CaptHindsight> yikes "Just curious about the Web-Based Configuration and Monitoring Interface in Linux RT targets. Will it be Silverlight based?" Answer: It is indeed silverlight/moonlight based.
[11:15:29] <kengu> this might be my next 3d printer, https://www.dropbox.com/s/81jlasdq2e989i2/20130616_001.jpg just need the extruding stuff=equipment and some control for it. i think a print volume of 20x20x50 is good enough se there will be some space around the object
[11:17:10] <CaptHindsight> glue guns are cheap
[11:17:59] <jdh> 20x20x50 inches?
[11:18:08] <kengu> cm
[11:18:09] <CaptHindsight> kengu: what used to be mounted on that stage?
[11:20:08] <archivist> usable hardware there
[11:21:11] <kengu> CaptHindsight: http://static.baza.farpost.ru/v/1300976474037_bulletin something like that and then previously http://www.eltesrl.com/index.php?option=com_content&view=article&id=89&Itemid=122&lang=en
[11:22:25] <kengu> jdh: it is something like 100cm * 100cm * 60cm or likes
[11:22:50] <jdh> steel frame?
[11:23:16] <kengu> yes
[11:23:24] <jdh> seems like a waste for a 3d printer
[11:23:46] <jdh> is cm a common unit for metric users?
[11:23:59] <kengu> do you have better ideas of use
[11:24:00] <jdh> everything I see is mm or m
[11:24:12] <kengu> jdh: well.. cm is just 10 mm
[11:24:22] <CaptHindsight> jdh: didn't you see the link from earlier? http://www.mebotics.com/microfactory.html Machine Shop In a Box
[11:24:27] <jdh> yeah. Just looked like it woudl have been too big to be mm
[11:24:28] <kengu> as m is 100 cm and 1000mm
[11:25:11] <jdh> I'm aware of metric prefixes :) Just not no-unit-specified == cm
[11:25:36] <jdh> Capt: missed that.
[11:25:36] <CaptHindsight> glue gun + Mill + lathe + arbor press is what I'm waiting for :)
[11:26:25] <jdh> I've never seen a printed part that was useful for anything other than "look at the cool thing I printed"
[11:26:32] <kengu> jdh: ah, umm.. it was the same line from another channel where the audience know without saying the unit
[11:27:10] <jdh> just curious.
[11:27:55] <jdh> anyone made a laser cutter/engraver frame?
[11:28:37] <kengu> nope. bought a chinese ready made (:
[11:28:50] <CaptHindsight> jdh: those parts don't get as much press
[11:29:44] <jdh> I almost bought a chinese one, but only the really sucky ones are cheap.
[11:31:46] <kengu> jdh: this is good, https://www.dropbox.com/s/oethgp3scfartg1/20130616_004.jpg
[11:31:53] <kengu> now with linuxcnc
[11:33:50] <jdh> nice. out of my price range though.
[11:35:09] <kengu> some $2000.. bargain
[11:36:23] <jmasseo> i watched someone do a sandcast from a 3d printed part.
[11:36:35] <jmasseo> might be more useful like that
[11:37:20] <jdh> yeah, that might make a useful part.
[11:39:39] <jdh> I'd like to make a ~ 30x45cm bed and 80w co2
[11:41:18] <CaptHindsight> but but aren't 3D printer supposed to be in everyone's home in 20 years?
[11:41:53] <jdh> sure. You can print your own jetpack and flying car
[11:42:38] <CaptHindsight> maybe i should invest in glue?
[11:54:21] <kengu> 30x45 is good size.. aren't the chinese cheap on that size
[11:57:25] <jdh> no. cheap ones are 20x30 with moshi crap
[11:58:03] <kengu> well.. moshi is easy to get away with
[11:58:19] <kengu> as in take off and replace with something else
[11:58:28] <jdh> sure, almost doubles cost though
[11:58:33] <kengu> and the something else is just a board with not much on it
[11:59:12] <kengu> as the drivers etc are not on that board so it basically just takes linuxcnc step and dir instructions from parallel port pins
[11:59:44] <kengu> at least that is what the two (the big) and then a small 20W one have
[12:00:25] <kengu> but the 20W one we just use as a 2d printer with cups and the moshi electronis (takes hpgl from parallel port)
[12:16:32] <IchGuckLive> hi all B)
[12:37:52] <IchGuckLive> yea burningman web castt is online 60.000 freaks in the dessert 1
[12:39:48] <Loetmichel> IchGuckLive: you one of the 60k?
[12:40:04] <IchGuckLive> one up in a time B)
[12:40:46] <Loetmichel> i meant: now
[12:41:10] <Loetmichel> could have been you have decided to take some "holiday
[12:41:11] <Loetmichel> "
[12:41:18] <IchGuckLive> no in the middle of a gread dark clowd slightly soth of you
[12:41:25] <Loetmichel> ?
[12:41:36] <Loetmichel> i hmow ehre you are
[12:41:42] <Loetmichel> know
[12:41:51] <Loetmichel> but could have been
[12:41:59] <IchGuckLive> i got about 2k US soldiers to drill this weekend on a famous rock walk way
[12:42:02] <Loetmichel> and great dark cloud?
[12:42:05] <Loetmichel> where?
[12:42:17] <Loetmichel> over here its Sunny since noon
[12:42:26] <IchGuckLive> oh lucky you are
[12:42:33] <Loetmichel> aehm...
[12:42:40] <Loetmichel> you are not SO far away
[12:42:48] <IchGuckLive> kaiserslautern
[12:42:49] <Loetmichel> so whre did that cloud came from?
[12:42:53] <Loetmichel> i know
[12:42:56] <IchGuckLive> France
[12:43:08] <IchGuckLive> or better the Lyoner alley
[12:43:27] <Loetmichel> oh, so i better use the car tomorrow to work? is there more coming from this direction?
[12:43:50] <Loetmichel> (instad of the motorcycle)
[12:43:52] <Loetmichel> +e
[12:44:01] <IchGuckLive> http://www.wetter.com/wetter_aktuell/niederschlagsradar/deutschland/
[12:44:14] <IchGuckLive> 6hr radar vorcast
[13:18:59] <IchGuckLive> ok im off by
[13:23:23] <ReadError> off by what?
[13:23:49] <ReadError> anyone have a good method of calculating a radius ?
[13:24:02] <ReadError> I have a 'pelican' style case i want to put some panels in
[13:24:15] <ReadError> but the corners are going to be the hardest
[13:24:21] <cradek> I have no idea what you're asking
[13:24:56] <kengu> just have some known radius parts or other round parts you can fit in the case and then measure the radius of those
[13:24:57] <ReadError> i guess i could just draw a box and make a circle that intersects at with the line on each side
[13:25:17] <ReadError> since length and width are easy
[13:28:10] <`Nerobro> there are lots of good methods of measuring radiuses.
[13:28:17] <`Nerobro> they're in your machinist books :-)
[13:28:28] <`Nerobro> I think there's half a dozen methods in machinerys handbook
[13:28:31] <`Nerobro> but for a pellican case?
[13:28:59] <`Nerobro> I'd measure the width, height, then measure the sides to the start of the curves
[13:29:03] <archivist> or in the tool draws (radius gauges)
[13:29:05] <`Nerobro> that'll give you something close enough.
[13:37:49] <andypugh> CAD. Measure width and height and then across the diagonals. Then draw it in a CAD package with the diagonal as a driven dimension, and tweak the radius until it works.
[13:38:41] <andypugh> (Or, alternatively, use the same measurements and some geometry)
[13:39:45] <andypugh> Actually, measuring the gap between the radius and the inner corner of a setsquare with the internal jaws of a caliper is probably the better way.
[13:40:55] <andypugh> (Geometry is still needed, and I am struggling to work it out in my head)
[13:48:22] <FinboySlick> ReadError: Is it a situation where you can measure the outside radius and offset by the material thickness?
[13:49:07] <ReadError> well finding the part where the line intersects the circle would be pretty hard by eye
[13:49:17] <ReadError> but i think i may have though of a way to draw it
[13:50:11] <jdh> I put a panel in a pelican box. Got a CAD drawing from their web site.
[13:50:14] <FinboySlick> ReadError: I'd do it using Andy's two suggested methods. Measure shortest distance between the inner corner of your square and the top of the radius, feed it to CAD.
[13:51:16] <ReadError> jdh, this isnt really an official pelican
[13:52:17] <jdh> this is why I need a laser cutter, so I can cut mylar/plastic/wtf templates for test fitting.
[13:52:31] <jdh> still can't talk myself in to it.
[13:54:19] <archivist> file and hacksaw :), card and scissors
[13:54:41] <copec> Total newb to even the cnc world here--I want to build a 3 axis system using a router to cut out templates and would like to use linuxcnc. What would you recommend as a stepper controller that is compatible with linuxcnc?
[13:54:42] <FinboySlick> archivist: But that's not high-tech!
[13:54:45] <archivist> or take a rubbing
[13:55:13] <copec> My knowledge base so far consists of roughly one hour of googling questions so far
[13:55:23] <archivist> or hight tech, take a picture and measure pixels in some package
[13:55:38] <FinboySlick> copec: Most 'cheapo' parallel port stuff will work if your computer can handle stepgen. Then you go up in price all the way to funky servocontrol.
[13:56:17] <Chemeleon> welcome to the rabbit hole copec :)
[13:56:49] <FinboySlick> copec: 'can handle stepgen' is not a matter of computing performance, btw. It's a bit hit-and-miss unless your hardware is already well known to work.
[13:57:13] <copec> Could you point me to some examples?
[13:57:30] <archivist> copec, stepper drivers, not controller, linuxcnc is the controller
[13:57:37] <ReadError> just get a g540
[13:57:43] <ReadError> its a solid device
[13:57:44] <ReadError> i own 2
[13:57:47] <ReadError> no issues at all
[13:57:48] <copec> archivist, thanks.
[13:58:26] <FinboySlick> ReadError: I googled g450 and went 'Wow, he has two?'
[13:58:44] <archivist> I have chinese stepper drivers and homebrew breakout
[13:58:53] <ReadError> FinboySlick, that would be nice ;)
[13:58:55] <Chemeleon> I went with one of the kits from www.automationtechnologiesinc.com I use mach3, not linuxcnc, but should be compatible I'd assume
[13:59:14] <jdh> he said mach3
[13:59:16] <ReadError> mach3 is a bad word.
[13:59:19] <FinboySlick> ReadError: Shame that your reality isn't as dyslexic as I am.
[13:59:23] <Chemeleon> hehe, figured there'd be a response like that ;)
[13:59:32] <jdh> let the shunning begin.
[13:59:35] <archivist> chorus of giggles
[13:59:43] <Chemeleon> I had one fluke issue with a stepper (the shaft just sheared off for no reason) but otherwise the gear from there has worked fine for me, and they replaced the bad motor
[14:00:09] <Chemeleon> possibly even worse, I'm writing my own cam software for windows :P
[14:00:26] <copec> I was trying to find a good site that gave a total overview of what people are doing now
[14:00:30] <FinboySlick> Chemeleon: But... why?
[14:00:36] <Chemeleon> considered going with linux, but I run windows for everything else, didnt want to hop OSes when moving between desktop and cnc
[14:00:38] <copec> There is just a lot of arbitrary information out there about it
[14:00:51] <ReadError> hop OS?
[14:00:55] <ReadError> i throw my stuff on dropbox
[14:00:58] <ReadError> go to basement PC
[14:00:58] <andypugh> copec: Ah, sorry, you came to the wrong place for an overview. We just do partisan and opnionated here :-)
[14:01:05] <ReadError> its there
[14:01:18] <Chemeleon> if you want information overload, chances are anything you'd want to know is buried somewhere on www.cnczone.com
[14:01:22] <jdh> ReadError: I just use samba
[14:01:22] <Chemeleon> finding it can be tricky though
[14:01:31] <ReadError> i have nfs too!
[14:01:32] <FinboySlick> Chemeleon: Write it portable then ;)
[14:01:33] <copec> well, I'm sort of an open information/free software junkie
[14:01:38] <Chemeleon> ReadError, havent yet extended my wifi to the workshop
[14:01:39] <ReadError> Samba BAD BAD BAD
[14:01:43] <copec> so I prefer that route
[14:01:47] <jdh> bad how?
[14:01:52] <Chemeleon> really should get on that one of these days, but need to put the range extender up in the attic, and its *hot* up there during the summer
[14:02:01] <FinboySlick> Samba works quite well.
[14:02:07] <ReadError> CIFS
[14:02:28] <ReadError> i just prefer nfs
[14:02:29] <FinboySlick> ReadError: Well, to share, you need samba.
[14:02:29] <ReadError> thats all
[14:02:36] <andypugh> Asn't CIFS just a rebranded Samba?
[14:02:36] <jdh> nfs on windows?
[14:02:50] <ReadError> jdh, yea, possible
[14:02:51] <FinboySlick> jdh: It exists, but I don't think you want to go there.
[14:02:54] <ReadError> but i only have 1 windows machine
[14:03:01] <jdh> I've been there, I don't lke it.
[14:03:03] <ReadError> rest are OSX or vmware
[14:03:04] <andypugh> AFP is the evil one, it leaves wierd files all over the place.
[14:03:10] <jdh> even with commercial pricey nfs for win
[14:03:15] <ReadError> OSX has native NFS support
[14:03:18] <Chemeleon> heh, the can of worms has been opened :)
[14:03:19] <copec> CIFS is the protocol--which is a replacement for SMB and quite superior
[14:03:41] <FinboySlick> Samba != SMB, for clarification.
[14:03:56] <jdh> I actually have a disk hung off my home router. I CIFS mount it on my cnc machines and also have it mapped on my winbox. Works great.
[14:03:56] <FinboySlick> It's the userspace bits.
[14:04:02] <andypugh> copec: Anyway, anything that you are likely to find, LinuxCNC can drive.
[14:04:28] <copec> It seems like the real time aspect is important for obvious reasons
[14:04:38] <copec> what about your ebay usb based stuff?
[14:04:46] <andypugh> No, not USB
[14:05:00] <andypugh> I forgot that part.
[14:05:14] <Chemeleon> nearly everyone seems to recommend sticking with parallel port from what I've seen
[14:05:27] <FinboySlick> Chemeleon: Or mesa boards.
[14:05:40] * FinboySlick still needs to install his :P
[14:06:02] <andypugh> Well, no, we tend to advocate Mesa boards, then sometimes remember to mention Pico in an attempt to appear fair-minded.
[14:06:31] <andypugh> And only suggest parport to folk who still seem to think this can be a cheap hobby :-0
[14:06:54] <archivist> as a cheapskate....!
[14:07:00] <Chemeleon> well, its not my most expensive one so far anyway :)
[14:07:23] <copec> I'm willing to pay more if It is a known relatively open solution and I'm not locked in to some vender
[14:07:25] <FinboySlick> Chemeleon: Give it time ;)
[14:07:42] <Chemeleon> FinboySlick, with any luck, it'll become a hobby that pays me instead now that I'm trying to sell software for it ;)
[14:08:01] <andypugh> copec: I would say strt with something like this: http://www.ebay.co.uk/itm/Germany-ship-Nema-23-Stepper-Motor-270oz-in-3A-3-Axis-Board-CNC-Kit-/271244550756 and then by the time you have blown it up you will know what you want. :-)
[14:08:05] <ReadError> whats revolutionary about your software Chemeleon ?
[14:08:07] <ReadError> i mean
[14:08:08] <Chemeleon> I'm probably going to have to look into usb boards for my next cnc router - want to build a smallish one I can keep on my desktop for dev work
[14:08:10] <ReadError> what sets it apart
[14:08:21] <Chemeleon> ReadError, the major thing would be price I suppose
[14:08:38] <Chemeleon> linux has a fair bit of free stuff, but on windows, its all way beyond typical diy/hobbyist budgets imo
[14:08:42] <archivist> Chemeleon, usb is a bad idea, poor latency
[14:09:02] <Chemeleon> yea, figured that'd be the issue with it
[14:09:07] <FinboySlick> archivist: He runs mach3, usb might actually help ;)
[14:09:16] <archivist> shh
[14:09:45] <copec> So do you guys just track down old pcs with parallel ports?
[14:09:53] <Chemeleon> www.diy-cam.com/downloads/diycam-carve/ the first program I just released, not super complex since its a heightmap carver
[14:10:02] <Chemeleon> but hoping it'll sell well enough to justify bigger things
[14:10:06] <FinboySlick> copec: That's the hit and miss bit.
[14:10:08] <archivist> copec, yes I track scrap
[14:10:23] <Chemeleon> copec, I had one in my junk room that was a few years old with parallel - doesnt take much to drive a cnc machine
[14:10:29] <FinboySlick> copec: If you want good timing, not all motherboards/chipsets are equal.
[14:10:43] <copec> What do you recommend
[14:11:00] <FinboySlick> copec: I have a fairly nice atom board that isn't being made anymore.
[14:11:04] <andypugh> copec: No need to track them down, lots of new motherboards have them (sometimes as a header on the MB)
[14:11:21] <copec> okay
[14:11:30] <FinboySlick> copec: The key is finding a board that has good latency characteristics.
[14:11:41] <cradek> looks like that does approximately what the image2gcode bundled with linuxcnc does
[14:11:52] <Chemeleon> cradek, quite likely
[14:11:56] <FinboySlick> copec: The newer boards often have management interrupts that you can't dodge and which can screw with your timing.
[14:12:08] <Chemeleon> does that one obey bit geometry, or just follow the pixel heights?
[14:12:17] <cradek> it obeys bit geometry
[14:12:30] <Chemeleon> its not a new concept, but on windows anyway, mine either works better, costs less, or both :)
[14:12:55] <Chemeleon> the vector program is the main one I want for myself, but thats going to be a much bigger undertaking, figured this one was a good way to warm up
[14:12:58] <cradek> heh, hard to cost less
[14:13:43] <Chemeleon> I found a few that were priced similarly but didnt work as well, and of course vectric's version costs $150
[14:13:56] <andypugh> Good report on the forum recently on the http://www.gigabyte.com/products/product-page.aspx?pid=4512#ov board. Has parport and various versions of PCI slot
[14:14:31] <copec> anyone use the smoothie project in here?
[14:15:21] <copec> The problem is that even though it'll probably never happen I want to set myself up to add axis's in the future
[14:15:24] <Chemeleon> I do have one feature I'm working on implementing currently that I've not seen done in any other similar apps
[14:15:31] <Chemeleon> generate a cutout path from the alpha channel of the image
[14:15:45] <Chemeleon> so you aren't limited to just rectangular carvings
[14:16:20] <archivist> copec, the add axis is a very good reason to stick with linuxcnc
[14:17:25] <FinboySlick> copec: ... unless you plan to add more than 6 ;)
[14:17:34] <archivist> I can see me wanting more that 5 axes :)
[14:17:56] <copec> I want to make an arm and then an iron man suit
[14:18:00] <andypugh> Worth noting that that Gigabyte MB has no CPU. The Intel Ataom boards were good that way, especially the ones with 12V power input.
[14:18:00] <copec> me end goal
[14:18:30] <copec> so they say on the linux cnc page to have dedicated graphics fairly often--with the open drivers
[14:18:40] <copec> Do you stick a video card in your atom board then?
[14:18:54] <andypugh> No, they work fine on the integrated video
[14:19:09] <copec> good to know
[14:19:20] <FinboySlick> copec: Usually better than with add-on video.
[14:20:32] <copec> I think this is the most helpful channel I have ever expirienced on freenode
[14:21:03] <FinboySlick> copec: We'll wait 'till you're all setup to be mean to you ;)
[14:21:09] <copec> s/expirienced/experienced
[14:21:43] <copec> Are there any gimble lock problems with 6 axis's that would make you need a 7th?
[14:21:46] * copec thinks about it
[14:23:08] <archivist> copec, I find things interfering is a big problem
[14:23:53] <pcw_home> andypugh: what card/daughtercard do you want SSI interface on?
[14:23:54] <archivist> rotary and headstock was about a thou apart today (it hit yesterday)
[14:24:04] <Chemeleon> dont know - I've yet to even look into moving beyond 3 axis, thats enough for me for now :)
[14:24:23] <Chemeleon> friend of mine keeps asking for a 4axis cam app so he has an excuse to extend his though, so that may happen eventually I guess
[14:25:15] <archivist> Chemeleon, inside rear of skull works well for multi axis on certain work
[14:25:31] <Chemeleon> yea, but if that software crashes, it hurts a lot more ;)
[14:27:27] <archivist> I need better gear measuring tools
[14:29:10] <FinboySlick> archivist: What are you working on lately?
[14:29:19] <archivist> FinboySlick, http://www.collection.archivist.info/archive/DJCPD/PD/2013/2013_08_19_bevel/
[14:29:27] <archivist> bevel gears
[14:30:38] <FinboySlick> archivist: Odd angle or just the way the picture was setup?
[14:31:03] <archivist> tooth width error I think is the main cause of that 90 degrees not being 90
[14:54:22] <FinboySlick> Might be a good time to move the electronics from their inconvenient spot at the back.
[15:17:22] <andypugh> pcw_home 6i25 seems sensible (as I haven't made the 7i80 work) and I don't think it matters which pins the SSI modules are on, as I don't have any SSI harware.
[15:26:12] <gene78> lo all
[15:28:09] <gene78> I am still trying to get the machine vision to work. One of the very consistently reported errors is ** (camview:10023): WARNING **: Unable to load pixbuf
[15:29:04] <gene78> Is there something in thyis kernel build that disables using the libpixbuf?
[15:31:52] <gene78> gtk2-engines-pixbuf 2.2--- is installed
[15:31:55] <archivist> I would have though unable to load was a fatal error not a warning, is that the real and total error text
[15:32:37] <AR_> fuck you
[15:32:57] <gene78> it isn't fatal, but seems to have the output on camview disabled because it can't use it
[15:34:35] <gene78> that seems to prevent camview from building a gui inset called emc.halio
[15:34:47] <gene78> inset/insert
[15:34:50] <archivist> seems pretty fatal to me, and what about was it the full and complete error message, any other text and numbers
[15:35:41] <gene78> gene@shop:~/linuxcnc/configs/my-mill-atom$ camview -c camviewcfg
[15:35:42] <gene78> ** (camview:10045): WARNING **: Unable to load pixbuf

[15:38:22] <archivist> use a pastebin for large amounts
[15:39:04] <gene78> I do get the crosshairs and a target circle but not the cameras output mixed in
[15:39:18] <archivist> I wonder why a certain person just escaped :)
[15:40:58] <gene78> Humm, I wonder if I should restrict the axis-letters to whats in this machine?
[15:41:35] <gene78> like XYZA only
[15:41:35] <archivist> reolve the error message rather than mess about
[15:41:43] <archivist> resolve
[15:47:29] <gene78> humm, I thought it was installed, but is not, and is not in the repo's! wtf???
[15:51:23] <gene78> Suggestions please?
[15:52:31] <gene78> the camera itself is enabled and seems to be delivering a stream of video at about 15 fps.
[15:53:58] <gene78> So I think pixbuf is the clue. OTOH, if i shut this down and fire up cheese, the camera also wakes up and works great

[16:34:43] <Aero-Tec> JT-Shop, are you around?
[16:35:08] <Aero-Tec> want to ask a quick question
[16:35:27] <JT-Shop> ok
[16:36:40] <Aero-Tec> I homed my lathes x axis with a dial gage, mounted it permanently on the lathe
[16:36:56] <Aero-Tec> I dial in zero and home x axis
[16:37:31] <Aero-Tec> will that auto zero tool 1 if I had zeroed it before using the fixture setting?
[16:38:36] <Aero-Tec> I am trying to follow and understand your website
[16:39:21] <Aero-Tec> I have swap out tooling tool post
[16:39:37] <Aero-Tec> quick change
[16:48:09] <andypugh> Aero-Tec: Yes, it should.
[16:48:28] <Aero-Tec> cool
[16:48:28] <andypugh> (A switch might be easier...)
[16:48:30] <Aero-Tec> thanks
[16:48:53] <andypugh> Bear in mind that the tool-post might be less repeatable than you would like.
[16:49:25] <andypugh> (Though that could just be my cheap Chinee one)
[16:49:55] <JT-Shop> yea, final X setting I use a micrometer on the part
[16:50:15] <Aero-Tec> when I update to mesa boards with more inputs and encoders with index I will get more fancy
[16:51:26] <Aero-Tec> JT when doing the final X setting do you mean every time you start the lathe or just when setting up?
[16:51:50] <JT-Shop> just when I replace a tool on my turret
[16:52:14] <Aero-Tec> ok
[16:52:33] <andypugh> What style of toolholder do you have?
[16:52:44] <JT-Shop> do you have an AXA type of tool post?
[16:53:31] <JT-Shop> http://www.use-enco.com/ProductImages/0904415-24.jpg
[16:54:08] <andypugh> How do they work?
[16:54:59] <andypugh> I am familiar with the "Dickson" style: http://www.lathes.co.uk/latheparts/page13.html
[16:55:28] <JT-Shop> same thing kinda
[16:55:43] <andypugh> "These toolposts have been widely copied in India and China - using inferior materials and indifferent standard of fit. You might be lucky and find a perfect example but amongst other faults reported are clamping pins that snap off, bases that are not flat, V-grooves out of parallel and toolholders that fail to contact fully with the guides and wobble about."
[16:55:48] <Aero-Tec> mine is just like this one
[16:55:50] <Aero-Tec> http://www.cdcotools.com/index.php
[16:56:24] <JT-Shop> which one?
[16:57:05] <Aero-Tec> BXA Quick Change Tool Post Set for 10 - 15" Lathe
[16:58:15] <Aero-Tec> that dickson look nice
[16:58:21] <JT-Shop> how close is the tool tip when you remove and replace it in the holder?
[16:58:38] <JT-Shop> I have the BXA wedge type on my Samson
[16:59:23] <Aero-Tec> seeing as it is a cheap chins one surprisingly good
[16:59:53] <Aero-Tec> well with in 1/2 thou
[17:01:01] <Aero-Tec> how good is yours?
[17:02:09] <JT-Shop> the Samson is a manual lathe...
[17:09:29] <JT-Shop> andypugh: does the screws with the cam looking thing lock the tool holder in somehow on the dickson?
[17:14:22] <andypugh> Yes, the screw pull in the piston things and clamp the toolholder against the V. At the same time the cam thingy fits round the disc on the adjusting screw and sets the toolholder to a fixed height.
[17:17:14] <JT-Shop> thanks, I was wondering how it worked
[17:20:44] <Aero-Tec> andypugh, do you like it?
[17:20:54] <Aero-Tec> good looking tool post
[17:21:08] <andypugh> I like the real ones.
[17:21:26] <Aero-Tec> looks like it would be very accurate
[17:21:59] <andypugh> My Chinese copy isn't as good, it is a bit soft and the V-ways have been marked by bits of swarf caught in there.
[17:22:38] <Aero-Tec> what does a real one cost?
[17:22:52] <andypugh> They are very accurate if the two V-ways are the same distance apart as the ones on the toolholders. This is definitlely true of the Dickson ones, less so the copies.
[17:22:54] <Aero-Tec> each holder must be a tad high as well
[17:24:24] <andypugh> https://www.cromwell.co.uk/publication_page_pdfs/1428/790.pdf
[17:27:41] <andypugh> That is an "Indexa" copy. This is a real "Dickson" http://www.ebay.co.uk/itm/Dickson-S5-Lathe-Toolpost-Set-Rare-/290962195978
[17:28:12] <JT-Shop> yiks
[17:28:13] <andypugh> Though to be fair that is a _very_ big one for 2" tools.
[17:28:15] <JT-Shop> e
[18:52:40] <nspiel> hello, does anyone know if the motor0dx and motor1dx need to be connected to the motor driver boards for mesa 7i43
[18:52:59] <nspiel> right now all i have hooked up is encoder power and ground and signal a and b
[18:55:12] <jdh> I have a 7i43, but no motor*dx
[18:55:28] <jdh> only using steppers/pwm/encoder though
[18:55:48] <nspiel> im using dc motor with encoder servo setup
[18:57:07] <jdh> are those index signals? do your encoders have index pulse?
[18:57:47] <nspiel> i dont think so? they are just regular quadrature encoders?
[18:58:08] <jdh> most encoders have a/b/z with z being index
[19:00:37] <nspiel> i have a b z yeah
[19:00:39] <nspiel> just looked at my motors spec sheet
[19:01:37] <nspiel> so z is motor direction?
[19:01:57] <jdh> no, Z is a one pulse-per rev index so it knows where it is
[19:02:05] <jdh> a/b phasing gives direction
[19:03:04] <nspiel> oh gotcha, so MOTOR 0 - P1 MOTOR 1 - P5 PIN# SIGNAL PIN# SIGNAL 1 GROUND 1 GROUND 2 MOTOR0IDX 2 MOTOR1IDX 3 MOTOR0A 3 MOTOR1A 4 +5V 4 +5V 5 MOTOR0B 5 MOTOR1B
[19:03:21] <nspiel> tthat didnt work
[19:03:47] <nspiel> oh ok got it!
[19:03:48] <nspiel> thank you!
[19:37:30] <eric_unterhausen> I ordered something from Misumi, they tried to fax something to me
[19:37:34] <eric_unterhausen> who does that anymore?
[19:38:28] <Chemeleon> its getting rare, but hasnt completely died out yet for some reason
[19:38:34] <eric_unterhausen> I figured lying to them about my fax number wouldn't be a big deal
[19:38:42] <eric_unterhausen> they tried to fax me 5 times
[19:41:14] * Valen pokes jp_
[19:41:25] <eric_unterhausen> of course while they were processing the order, my credit card was stolen by someone in Illinois
[19:48:08] <nspiel> what is the correct way to make the headers that go on the mesa boards? I have the headers with wires in them but i want to take the wires out and put new ones in
[19:50:14] <cradek> be careful to not pull the pins out or break any plastic tabs when you remove the old wire. there is a special tool for crimping it, but a bench vise or a machine vise both will work fine.
[19:50:30] <cradek> I bet they're really not meant to be reused, but we've all done it anyway.
[19:52:42] <eric_unterhausen> there would have to be a really good reason for me to take the wires out of a 50 pin ribbon cable
[19:54:08] <Jymmm> Most ppl just roll the connector into the cable to shove it thru a 1/2" or so hole
[19:55:17] <eric_unterhausen> yeah, it's amazing how small it will get if you are desperate
[19:58:14] <nspiel> problem is I dont have a bench vice haha
[20:03:09] <nspiel> can u crimp them with pliers or something like that
[20:03:20] <Jymmm> Not reliably
[20:04:32] <Tom_itx> in a pinch i've slammed a drawer shut on em
[20:04:37] <nspiel> is the tool called a wire crimping tool or something else
[20:04:38] <nspiel> lol
[20:04:39] <nspiel> tom
[20:04:44] <Tom_itx> it works
[20:07:23] <Jymmm> IDC Crimper iirc
[20:08:31] <Jymmm> yep, that's it
[21:06:36] <pcw_home> nspiel: I did a detailed list of how to connect the two 7I25s to one 7I43 connector, it should be findable in the IRC logs
[21:08:32] <nspiel> sorry to be a noob but what are the IRC logs?
[21:08:39] <Tom_itx> logger[mah]_
[21:08:39] <logger[mah]_> Tom_itx: Log stored at http://linuxcnc.mah.priv.at/irc/%23linuxcnc/2013-08-20.html
[21:08:41] <Tom_itx> that
[21:18:12] <nspiel> but wasnt it just detailing connecting the 7i43 via the split 50 wire connector? I already did that.I am now working on wiring that setup to my robot arm
[21:19:54] <pcw_home> OK, so this is just wiring the7I25 encoder and motor connectors?
[21:20:06] <nspiel> yep
[21:20:18] <nspiel> but im making the female headers to connect to the robot
[21:21:51] <nspiel> it basically has a giant parallel output port on the back breaking out to a connector with a big ribbon cord that i have to pull all the encoder power and signals from then wire that to the 7i25s
[21:37:54] <jp_> seen valen?
[21:41:23] <Valen> yes
[21:41:26] <Valen> yes you have
[21:41:55] <jp_> just pulled the 7i33 from the mill
[21:42:55] <Valen> all good?
[21:43:08] <jp_> yep
[21:43:33] <Valen> PM?
