[00:05:33] <Jymmm> That lil hand crack generator has big, little, big, little gears in it. Going from big to little I get, but what does using two pair of them suppose to give you?
[00:06:25] <Jymmm> http://img143.imageshack.us/img143/4936/cimg8116.jpg
[00:06:38] <Jymmm> err three pairs
[00:06:41] <JT-Shop> more gears
[00:06:58] <Jymmm> JT-Shop: for what purpose?
[00:07:08] <andypugh> They multiply
[00:07:09] <JT-Shop> more gear reduction
[00:07:19] <JT-Shop> like rabbits
[00:07:22] <Jymmm> andypugh: multiply rpm?
[00:07:29] <andypugh> 5:1 x 5:1 x 5:1 = 125:1
[00:07:42] <JT-Shop> hmmm didn't ask me so I'll stay silent
[00:07:49] <andypugh> You will find they are loose on the shafts.
[00:08:02] <Jymmm> JT-Shop: multiply rpm?
[00:08:07] <JT-Shop> yes
[00:08:18] <JT-Shop> or divide as the case may be
[00:08:32] <Jymmm> ah, ok. I didn't know that.
[00:08:34] <andypugh> And that's actually 4 stages. so you probably have about 500:1
[00:09:24] <Jymmm> Well, the points the shafts rest on are total crap, or it actually might work nicely.
[00:09:39] <andypugh> The shafts are static
[00:09:48] <Jymmm> even have grease on them
[00:10:13] <Jymmm> andypugh: Well, they are SUPPOSE to be, be the points they rest on shift and the shafts/gear seperate
[00:10:22] <PCW> might be only 2 stages with doubled gears for more torque
[00:10:43] H264 is now known as WalterN
[00:11:16] <andypugh> Could be, but I would be surprised.
[00:11:42] <Jymmm> Could I buy gears like that?
[00:12:03] * JT-Shop listens to Rhythm of the Rain by...
[00:12:34] <JT-Shop> opps Rhythm of the Falling Rain
[00:12:36] <Jymmm> brass ones that is
[00:12:44] <JT-Shop> yea
[00:12:49] <JT-Shop> mcmastercarr
[00:12:55] <andypugh> www.hpcgears.com
[00:13:40] <andypugh> Nothing wrong with nylon gears though.
[00:14:10] -!- Loetmichel has quit [Ping timeout: 276 seconds]
[00:14:42] <andypugh> I know a car with a rawhide primary drive gear (and one of my bikes has one too)
[00:15:25] -!- robh__ has quit [Ping timeout: 240 seconds]
[00:15:29] <PCW> so i f those are 1-3 then 1 RPS crank and 4 stages is 81 RPS or ~5000 RPM
[00:16:29] <PCW> I guess that's about right
[00:16:44] <Jymmm> I'll probably try this before making my own http://www.amazon.com/SOS-Charger-Hand-Crank-Emergency-Flashlight/dp/B002WRKZZ4
[00:18:28] <JT-Shop> anyone install EMC on 11.04 yet?
[00:18:56] <Jymmm> I wonder if I could do something like a foot powered sewing machine, but I think that would need a flywheel of some sort

[00:19:41] <JT-Shop> nope look it up
[00:19:53] <Jymmm> JT-Shop: Nah, I believe ya
[00:19:56] <JT-Shop> Webb Peirce did it with Willie too
[00:20:18] <JT-Shop> never smoke weed with Willie again LOL
[00:20:28] <Jymmm> heh
[00:20:45] <andypugh> Bother! other than the commit, I seem to have deleted all this evening's work.
[00:20:55] <Jymmm> the man is so famous, and STILL gets busted for pot. That's sad.
[00:21:07] <JT-Shop> that sucks
[00:21:11] <andypugh> Not the end of the world, I have done all the thinking part, just need to re-type it.
[00:21:14] <JT-Shop> http://www.youtube.com/watch?v=kiVDtll8th0
[00:21:34] <Jymmm> andypugh: how did you delete it?
[00:22:03] <andypugh> It was in a git branch I didn't think it was in, and I was tidying up.
[00:22:18] <Jymmm> ah
[00:22:37] <Jymmm> JT-Shop: Btw.... EEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE Haaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
[00:22:53] <JT-Shop> I know you love it Jymmm
[00:23:13] <Jymmm> JT-Shop: as much as you like G6
[00:23:14] <andypugh> What colour is that suit?
[00:23:46] <JT-Shop> not sure
[00:24:01] <Tom_itx> i wonder if anyone has tried building bitfiles after i posted how to get it working
[00:24:21] <andypugh> I read a book recently in which a character has a suit in International Klein Blue.
[00:24:23] <JT-Shop> one looks purple
[00:24:41] * JT-Shop heads in to be chef of the day
[00:24:46] <andypugh> Tom_itx: I think cncbasher makes bifiles.
[00:25:27] <PCW> Yeah isssy too
[00:26:41] <Jymmm> JT-Shop: http://www.youtube.com/watch?v=W8nYlgOUJNo&feature=related
[00:28:15] <Jymmm> need 18" JBL w/ 1K watt amp to give it any justice

[00:37:59] <andypugh> Jymmm: I rather like this. Interesting how something purely orchestral can sound sad. http://www.youtube.com/watch?v=JSAd3NpDi6Q
[00:39:14] -!- atom1 [atom1!~tom@ip68-102-109-205.ks.ok.cox.net] has joined #emc
[00:39:31] <Jymmm> andypugh: That I like. I can truely understand why all the REALLY BIG movies have always used orchestras
[00:39:46] <andypugh> Jymmm: A very large man with a very small guitar.
[00:40:18] <Jymmm> andypugh: and a damn good voice
[00:40:56] <andypugh> Aye.
[00:41:34] <Jymmm> Though I've come to find that what I enjoy most are songs with a) deep bass and/or b) Spanish guitar.
[00:42:18] <Jymmm> And of course my gf hates me for it too =)
[00:42:34] <andypugh> I love Memories of the Alhambra:
[00:43:35] <Jymmm> My biggest issue is that I love LOTS of music, but I have nfc on the title or artist of most of them
[00:44:11] <Tom_itx> that one dude isn't around anymore is he?
[00:44:22] <Jymmm> no =(
[00:44:33] <Tom_itx> i kinda like transiberian orchestra
[00:44:43] <Tom_itx> they come around here every christmas
[00:44:46] <Jymmm> Tom_itx: Their not bad
[00:45:00] <Jymmm> a bit cliche,
[00:45:13] <andypugh> I seem to have a taste for female vocalists. And I think that Sinead O'Connor's "Nothing Compares" was stunning.
[00:48:44] <PCW> how about florence welch?
[00:48:46] <PCW> http://www.youtube.com/watch?v=_gMq3hRLDD0
[00:49:55] <andypugh> Favourite at the moment is Amy MacDonald.
[00:51:09] <Jymmm> andypugh: Her voices "grows" on you... http://www.youtube.com/watch?v=0B7sH5QLyXY
[00:51:21] <Jymmm> s/voices/voice/
[00:52:59] <Jymmm> Mind you it took me ten minutes to even try to remember her name
[00:53:30] <andypugh> Anyway, I should be asleep.

[14:34:09] <skunkworks> I just try not to complain too much about the tool path it generates.
[14:46:35] <skunkworks> I really should look into something better.

[15:45:26] <Tom_itx> emc wants to be boss
[15:47:25] <archivist> is he is miss understanding step dir open loop with closed loop
[15:47:26] <cradek> wonder what "Enable Input Filter" is/does/means
[15:47:40] <cradek> is that an option on the amp?
[15:48:13] <skunkworks> sounds like it
[15:48:16] <archivist> looks like it is on the amp
[15:48:43] <skunkworks> "Input filter" option is not for signal quality, but for step pulse (or any other input mode) jitter & noise reduction. It also smoothens motion if input multiplication is being enabled on drive (like moving 5 counts on one step pulse).
[15:50:36] <skunkworks> if I remember right - he has pretty low gearing (rack) like 1.5 turns per inch or such.
[15:51:12] <skunkworks> which seems a bit much for the servos..
[15:51:31] <archivist> rack? that rings a backlash warning bell

[16:35:08] <pcw_home> Almost looks like an extrapolation bug (you would expect extrapolation to be disabled if there's no "filtering" bu who knows)
[16:37:02] <Danimal_garage> morning
[16:37:10] <cradek> emc folks have occasionally made the mistake of making something an option when one choice makes it work well and one choice makes it work badly. I suspect their software just lets you set it in such a way that it works badly.
[16:38:02] <cradek> pcw_home: is the parport-replacer to make good quality step/dir for an existing parport based setup available and working yet?
[16:38:21] <cradek> I haven't been keeping up...
[16:38:25] <pcw_home> Yes in 2.5
[16:38:34] <cradek> awesome. what's it cost?
[16:38:46] <pcw_home> $89 for the FPGA card
[16:39:48] <JT-Shop> yep it is working :)
[16:39:51] <cradek> ah ok, I expected it to be cheaper than 7i43
[16:39:54] <cradek> JT-Shop: :-)
[16:40:34] <pcw_home> thats the 5I25, physically it looks like a low profile dual parallel port card
[16:41:06] <JT-Shop> I hope to connect up a couple of g203v's and steppers this evening
[16:41:15] <cradek> ah, dual is neat
[16:41:39] <pcw_home> Its hard to get much lower price wise without compromises and also maintain some resale margin for dealers
[16:41:57] <JT-Shop> cradek: the 7i67 has a zillion terminal blocks
[16:42:27] <cradek> yeah I'm not saying it's overpriced, I just mean it'd be hard to choose that over 7i43, losing a lot of flexibility for the sake of a little simpler wiring
[16:43:23] <cradek> making something that every black box stepper driver can plug in to and work perfectly at whatever step pulse speed it needs is a very clever hack.
[16:43:29] <pcw_home> Its also faster as its a PCI card (maybe 1/12 the overhead)
[16:44:26] <JT-Shop> I think the parallel cable between the 5i25 and the 7i67 is a wonderful thing
[16:44:32] <cradek> yes good move, I am really starting to dislike the EPP based stuff - it gives people endless trouble, while also failing to placate the parallel-port-disappearing whingers
[16:44:55] <pcw_home> Since it has no bridge and everythings in the FPGA it is more of a pain to update the firmware
[16:45:40] <cradek> sounds scary
[16:46:06] <pcw_home> I was amazed at how good the IEEE 1284 EPP cables are for signal fidelity
[16:46:41] <cradek> is firmware change via jtag only?
[16:47:11] <cpresser> what fpga don you use? altera, xilinx, others?
[16:47:52] <pcw_home> No you can do it via PCI (you write the EEPROM and then power cycle)
[16:47:54] <pcw_home> The current setup has some backup so if for example you crash or lose power during an update its recoverable
[16:48:49] <pcw_home> 5I25 uses Xilinx Spartan 6
[16:50:50] <pcw_home> JTAG is only if you make do something fairly bad like load a config that matches the chip but doesnt work (common during devel)
[16:53:19] <cradek> hm I guess if I want pci, 5i25 is much cheaper than all the other options
[16:54:37] <cradek> what is 7i67? I don't see it on the price list or site
[16:54:55] <pcw_home> JT transposition of 7I76
[16:56:04] <cradek> ah - awesome
[16:56:14] <cradek> found the manual but not the price
[16:56:28] <pcw_home> more that the FPGA card!
[16:56:38] <cpresser> is there a system behind naming all those cards?
[16:57:05] <cpresser> its quite confusing without understanding the scheme
[16:57:58] <pcw_home> just serial (well 5 series cards are PCI, 6 are PCIE. 4 are PC/104, 7 are external (no bus))
[16:59:03] <cradek> "what works with what" is the very complex question that doesn't seem to have an answer on the site
[16:59:32] <pcw_home> 7I76 is $119
[16:59:33] <pcw_home> Theres a similar card with no expanded I/O (7I78) thats much cheaper ($39 I think)
[16:59:37] <cradek> I agree the names aren't very meaningful but it's sure nice that you can find them with no noise on google
[16:59:38] <cpresser> pcw_home: you sould put that simple info on the homepage :)
[17:00:20] <pcw_home> but I mungled up the spindle DAC so the 7I78 needs a new spin
[17:01:40] <A2Sheds> is c = cpu, i = IO, p = power supply, cfadpt = compact flash adapter, isio = isolated IO, x = external ?
[17:02:05] <cradek> lunch, bbl
[17:02:39] <pcw_home> Andy has been doing great work getting the 7I76 I/O up and running
[17:02:41] <pcw_home> Yes and we used to have M (when we started we made CMOS RAM disk emulators and CMOS CPUs for passive ISA bus)
[17:03:49] <pcw_home> Shows how old I am...
[17:05:07] <cradek> I hand-wired some ISA cards in my time. it was very accessible to the experimenter.
[17:05:41] <pcw_home> Yes I think that part of what keeps PC/104 alive even today
[17:05:47] <A2Sheds> pcw_home: do you have any Annabooks kits from the 80's? XT BIOS, EEprom, the Flash kit before they had wear leveling?

[20:34:13] <AofA> hello. I am trying to install emc and am having problems with ubuntu (fairly old machine). will emc work well on xubuntu?
[20:34:47] <JT-Shop> much easier to try the 8.04 LiveCD on your old machine
[20:34:53] <cradek> what spec of machine is it?
[20:35:01] <cradek> and what problems are you seeing?
[20:35:22] <AofA> celeron 1.1 with 256 ram
[20:35:57] <cradek> hm yeah, not sure if that will even boot the live cd far enough to install.
[20:36:10] <AofA> it boots from the cd, takes for ever, and then says it can't find a file system
[20:36:12] <cradek> perhaps if you already have a swap partition it can find early on
[20:36:37] <cradek> you have to go back pretty far to find an ubuntu release that doesn't bring up all of the gnome desktop before installing
[20:36:38] <AofA> this machine has xp on already, working
[20:37:03] <AofA> is my problem the memory?
[20:37:15] <cradek> perhaps finding another machine would be the easiest way to proceed
[20:37:31] <AofA> because of memory issues, or processor speed?
[20:37:33] <cradek> yes I think it is very likely to be the memory that's the immediate problem
[20:37:52] <cradek> the second problem may be that you don't have a local APIC and the realtime kernel will not work
[20:38:01] <JT-Shop> viewing from the positive X end should the A axis rotate CW for +?
[20:38:20] <cradek> JT-Shop's advice about trying the linuxcnc ubuntu 8.04 live cd is good, but I think you may still need more RAM first
[20:38:56] <AofA> I see... are we talking 512, or at least a gig?
[20:39:03] <cradek> I use a pentium 3 machine that was given to me for free to run one of my mills
[20:39:12] <cradek> depending on where you are, maybe you can find a machine very cheaply
[20:39:29] <AofA> I got this one for equiv to 30 usd
[20:39:44] <AofA> you get what you pay for... :)
[20:39:52] <cradek> 512 might be enough to get the linuxcnc ubuntu 8 install to run
[20:39:58] <FinboySlick> I have a 550Mhz ALIX board with 256MB of ram and it boots the current ubuntu EMC livecd so I don't think RAM is his issue.
[20:40:13] <FinboySlick> And I don't have any swap.
[20:40:25] <cradek> FinboySlick: can it actually install?
[20:41:09] <cradek> https://help.ubuntu.com/community/Installation/SystemRequirements
[20:41:20] <cradek> this says 1 GB RAM for the current version
[20:41:27] <FinboySlick> cradek: Yeah. It's not terribly fast, but not terribly slow either. Lacks a 'standard' APIC and it would require a kernel recompile to work.
[20:41:43] <AofA> thats why my original question was if xubuntu could be used
[20:42:12] <cradek> AofA: you will still have trouble using our kernel, lacking a LAPIC
[20:42:14] <FinboySlick> cradek: I don't think the emc livecd is the current version, it's a LTS.
[20:42:42] <cradek> if so, you are faced with rebuilding all of rtai, linux kernel, and emc on your 256 MB machine
[20:43:14] <cradek> to answer your specific question, emc doesn't care what window manager and/or desktop environment you use, but I suspect you are asking the wrong specific question
[20:43:23] <FinboySlick> cradek: I'll be cross-compiling ;)
[20:44:01] <AofA> I am a linux virgin, so it sounds like it will be easier to get more memory
[20:44:20] <FinboySlick> AofA: Not when there's no solderpoint for it.
[20:44:21] <cradek> yes, and try the cd based on ubuntu 8
[20:44:22] <Tom_itx> JT-Shop, i'm not sure if this is even remotely close to your question: http://en.wikipedia.org/wiki/Euler_angles
[20:45:06] <cradek> JT-Shop: iirc, the original ngc doc specifies the rotation direction in the "definition of a machining center" section
[20:45:20] <JT-Shop> ok, thanks
[20:46:14] <Tom_itx> the gimball looked cool though :)
[20:48:00] <AofA> many thanks
[20:48:08] <cradek> welcome, hope you succeed
[20:53:26] <JT-Shop> cradek: thanks I found it here http://linuxcnc.org/docs/html/common_machining_center.html#r1_2_2
[20:55:20] <A2Sheds> FinboySlick: whats the latency like in it's current state?
[20:55:47] <FinboySlick> A2Sheds: Sadly couldn't test, I need to build a kernel to use its bastard APIC.
[20:55:58] <FinboySlick> (if it does have one)
[20:56:26] <A2Sheds> FinboySlick: I'd have to check my old docs
[20:56:52] <FinboySlick> A2Sheds: Actually, I'm pretty sure there's a kernel config entry like 'Geode APIC' or somesuch.

[23:28:52] <Jymmm> I remember trying it as a kid, but never ever could get a fire started.
[23:28:53] <FinboySlick> Jymmm: On gasoline, it works okay.
[23:29:12] <Jymmm> FinboySlick: intensionally?
[23:29:46] <andypugh> I think ether would be better. Or meths
[23:29:47] <FinboySlick> Jymmm: Nah, I just couldn't see the inside of the tank very well.
[23:30:09] <andypugh> Did the eyebrows grow back?
[23:30:13] <Jymmm> FinboySlick: Ok, I was gonna say. You lit the fumes, not the fuel.
[23:30:26] <tom3p> JT-Shop: when the thc.z-pos-out creates a new position, is it syncd to a servo period? (or are you out walkies now?)
[23:30:40] <FinboySlick> I'm not serious here, btw... I do dumb things but that's a bit beyond my scope.
[23:31:15] <Jymmm> andypugh: Well, I FINALLY was able to using cotton ball + vasline and about ten strikes of the wheel
[23:31:26] <Jymmm> vaseline == petrolium jelly
[23:32:07] <Jymmm> In perfect cnditions, no wind etc
[23:33:10] <Danimal_garage> ti always cuts so pretty on the lathe (with good tools)
[23:33:24] <Jymmm> Danimal_garage: plate? rod?
[23:33:52] <Danimal_garage> both, but sheet in this case
[23:34:12] <andypugh> A friend of mine did that for real soldering copper tacks into a rusted tank to stop leaks.
[23:34:30] <Jymmm> Danimal_garage: can _you_ thread ti rod?
[23:34:48] <Jymmm> err tube
[23:34:54] <Danimal_garage> can i? probably, never needed to
[23:35:47] <Jymmm> k
[23:36:00] <Danimal_garage> havent needed to do any threading on the cnc's yet
[23:36:08] <Danimal_garage> except thread milling once
[23:36:17] <Jymmm> ah
[23:36:21] <Danimal_garage> on my machines anyways
[23:36:37] <Danimal_garage> i basically just make the same parts day in and day out
[23:36:49] <Danimal_garage> anything different is usually done on my manual machines
[23:37:22] <Tom_itx> time to invent a new product line
[23:38:08] <Danimal_garage> sure, when this one stops paying the mortgage
[23:38:50] <Tom_itx> you just sounded bored
[23:39:25] <Danimal_garage> with work? sure, but it allows me a lot of time to do other fun stuff
[23:40:09] <Jymmm> Danimal_garage: beer and to see something nakkid
[23:40:17] <Danimal_garage> exactly
[23:40:52] <Danimal_garage> Jymmm gets it
[23:43:31] <Danimal_garage> i just want to build the brand up enough so i can eventually sell
[23:43:43] <Jymmm> 1:15 - 1:55 http://www.youtube.com/watch?v=swEE_XsBsdM
[23:44:00] <Danimal_garage> cant watch it on this pc, it's locking up
[23:44:09] <tom3p> JT-Shop: 4later... i see the comp creates a velocity not a position.
[23:44:10] <tom3p> is the value averaged during the servo period or is the immediate value used whenever its polled?

[23:45:25] <JT-Shop> tom3p: back for a bit
[23:46:55] -!- mozmck has quit [Ping timeout: 260 seconds]
[23:48:00] <tom3p> JT-Shop, i dont know how fast the THC voltage varies. does it change much during one servo period ( 1mSec ) ?
[23:48:18] <Jymmm> THC !!! THC !!! THC !!!
[23:48:29] <tom3p> if so, the immediate value could be less than desirable
[23:50:00] <tom3p> so i asked if it was filtered in any way, like averaged or integrated ( just an rc on the low voltage analog of the tip voltage )
[23:54:14] <JT-Shop> I've thought about setting up a P term for it, but have been side tracked
[23:54:50] * JT-Shop goes for another bucket of H2o
[23:55:27] <andypugh> tom3p: Use a lowpass in HAL?
