[03:28:25] <Loetmichel> mornin'
[04:25:50] <_abc_> Hello. If I have the ubuntu lts 10.04 based linuxcnc installed on a hdd, will I break axis/linuxcnc if I upgrade only the tcl and tk packages manually to a higher version? I need some features which are not present in the packages on lts 10.04 . I can install from source by hand, but I need to know if it will wreck the linuxcnc install.
[05:53:00] <jthornton> my swag is you can try then if it "wrecks" something you can revert it...
[05:55:31] <archivist> similar to, make part, measure, adjust gcode, rinse repeat till you get a good one
[05:55:46] * jthornton looks again to see that he is gone...
[05:56:07] <jthornton> I should look first then answer...
[05:57:01] <archivist> he is in ##electronics
[06:17:28] <Lathe_newbie> hi... have a little question... when i want to select an axis encoder in pncconf, i cant find them, but they are declared in the xml file, can anyone tell me why?
[06:21:45] <jthornton> pncconf is pretty complicated and the only one that understands it is the author and he hangs out in the forum
[06:22:41] <jthornton> Lathe_newbie, what mesa card are you using?
[06:27:00] <jthornton> I guess he left
[06:28:38] <Lathe_newbie> 5i25
[06:28:46] <Lathe_newbie> i think i have the mistake
[06:28:52] <jthornton> ok
[06:28:53] <Lathe_newbie> in the .xml file is written Qcount
[06:28:56] <Lathe_newbie> i changed to encoder
[06:28:59] <Lathe_newbie> and will retry
[06:30:09] <jthornton> what .xml file are you talking about?
[06:33:25] <Lathe_newbie> one, pcw has done for me
[06:33:51] <Lathe_newbie> i have 3 ecoders, they were caled qcount in the xml file... iv i change to encoder, it works
[06:36:23] <jthornton> ah
[06:37:44] <Lathe_newbie> for a selfmade firmware file
[06:37:58] <Lathe_newbie> but there i added 3 ecoders
[06:38:10] <Lathe_newbie> and there was none selectable in pncconf
[06:38:19] <Lathe_newbie> cause they were called qcount and not encoder
[06:55:02] <Lathe_newbie> is it possible, to developp a own smart serial daughter card?
[06:55:14] <SpeedEvil> Sure.
[07:48:53] <JT-Shop> nice and cool this morning
[07:49:42] <CaptHindsight> http://hackaday.io/project/283-PCB-mill-for-under-%2410 "I just want to see if this is possible. I'm open to ideas and criticism, so let me know what you think" does he really want to know? :)
[07:53:39] <DaViruz> really brings out the "hack" in hackaday
[07:56:37] <CaptHindsight> http://static.projects.hackaday.com/images/7473421395966060236.jpg success?
[07:59:26] <archivist> stop linking fails!
[07:59:31] <archivist> :)
[07:59:44] <syyl_> is it rude to say, that it would look better if done freehand with a dremel?
[08:00:46] <CaptHindsight> they ask for criticism/help/advice and then attack you for trying to edify them
[08:01:33] <syyl_> must have a reason why even my manual engraving machine weights about 200kg ;)
[08:02:13] <syyl_> all this make-movement, reprapstuff and "new industrial revolution" thing is nice
[08:02:29] <CaptHindsight> a recent term I've heard to describe machines like yours is "overbuilt"
[08:02:47] <syyl_> ;)
[08:03:18] <syyl_> but nice thoughts dont replace proper engineering or common sense
[08:03:19] <CaptHindsight> the mindset is that it's supposed to be inexpensive and almost work a few times, like HF tools
[08:03:31] <archivist> they are clueless about dynamics, spring of machines etc
[08:03:41] <syyl_> my engraving machine is about 50 years old
[08:03:55] <syyl_> and holds half a thousand without a problem
[08:04:54] <CaptHindsight> try to have this conversation in a channel like #reprap :)
[08:05:16] <archivist> none of the idiots realize the cutting force bends the machine
[08:05:30] <syyl_> no way, CaptHindsight :D
[08:05:40] <DaViruz> oh, that printer deal just friction feeds the board like it was paper
[08:05:48] <syyl_> i may not be an old grumpy machinist
[08:05:55] <DaViruz> i'm sure thats very repeatable after its been fed back and forth a couple hundred times
[08:06:01] <syyl_> but i can be grumpy ;)
[08:06:49] <Tom_itx> archivist, idiots are put here to make us look good
[08:06:51] <archivist> I was making a cd printer using the roller idea 15 years or more ago, roller creep, it is real
[08:07:19] <Tom_itx> and they breed like rabbits
[08:07:49] <CaptHindsight> even the cheap Epson printers have a rack gear molded into the tray for printing CD's
[08:07:57] <syyl_> i want to buld a vmc from plywood, floppy drive steppers and rubberbands!
[08:08:10] <archivist> this was long before the epson did that
[08:08:54] <Loetmichel> hmmm
[08:09:12] <Loetmichel> i would at least uses a 1/8" ball bearing aht that "router bit"
[08:09:20] <Loetmichel> and nor let it run in plastic
[08:09:24] <Loetmichel> used
[08:09:34] <syyl_> i would substitute it by chunk of machine
[08:09:37] <CaptHindsight> http://hackaday.io/project/998-Affordable-Metal-3d-Printer melted his extruder trying to print tin
[08:10:47] <CaptHindsight> yikes "I've taken the RepRap philosophy to heart. There are no swiss-machined parts and crazy Japanese bearings in this machine."
[08:11:20] <archivist> hehe
[08:11:23] <CaptHindsight> no properly fabricated components for me :)
[08:12:17] <Loetmichel> hmmm
[08:12:33] <Loetmichel> i would think the took the 3dprinter philosophy to far
[08:12:40] <CaptHindsight> they wear their ignorance like a badge on their chest
[08:12:45] <Loetmichel> you can only do so much with plastics
[08:12:47] <Loetmichel> ;)
[08:13:14] <Loetmichel> i just happend to get a reprap i3 mechanics kit.
[08:13:29] <Loetmichel> ... fairly useable but could be better
[08:13:50] <archivist> I suppose they will learn the basics, because they will have failures
[08:13:54] <Loetmichel> i am in the process of filing all the dropout filaments and nozzle clogs away
[08:14:00] <Loetmichel> ;-)
[08:20:04] <CaptHindsight> does anyone recall seeing a machine thats acts like hands on clay on a pottery wheel for shaping sheet metal?
[08:20:28] <CaptHindsight> it wasn't like a typical metal spinner with a form that the metal gets pressed against
[08:22:18] <archivist> Ford made a cnc press that uses two wheels to make any tin shape
[08:22:50] <CaptHindsight> sounds similar, yes using two wheels
[08:23:06] <archivist> I saw a a video on TV with some of the operation hidden
[08:23:37] <archivist> effectively a cnc wheeling machine
[08:23:53] <CaptHindsight> might be the one I saw
[08:25:37] <archivist> probably a million patents on the process
[08:25:37] <CaptHindsight> http://www.youtube.com/watch?v=iNQ40MYwZqw here it is
[08:27:49] <archivist> yup, thats the machine, not sure if that was the vid I saw
[08:29:08] <archivist> that looked a bit like a hard stylus/ball bearing pressure point
[08:29:25] <CaptHindsight> same concept as what I recall
[08:30:24] <archivist> ah well, at least our memories are ok....
[08:33:31] <archivist> I think linuxcnc can be coaxed to do that too
[08:34:03] <archivist> the kins for the upper/lower bot probably already exists
[08:35:15] <CaptHindsight> yes, it does
[08:41:39] <archivist> a scroll through and one can see both are the same type, and the narrator calls it a stylus too
[08:41:51] <CaptHindsight> http://www.youtube.com/watch?v=xcg08U_Y4PI http://www.youtube.com/watch?v=AnMW_YuMLh8
[08:42:11] <CaptHindsight> Single Point Incremental Forming (SPIF)
[08:42:42] <CaptHindsight> http://www.youtube.com/watch?v=lRm2ifaUrGg
[08:43:47] <archivist> II bet there is an impulse (hammer action)
[08:44:48] <CaptHindsight> http://www.youtube.com/watch?v=eh0ddqsx0KI
[08:45:33] <archivist> I have someone here will have to watch later
[08:46:30] <t12> cool process
[08:47:10] <CaptHindsight> nice way to make low volume formed parts
[08:47:53] <t12> has anyone done PID + resonance filtering in linuxcnc?
[08:49:15] <t12> for servo control
[08:49:26] <CaptHindsight> few use servos
[08:50:40] <t12> i guess it could all just be implemented in the pid module?
[08:50:58] <pcw_home> Theres a biquad filter comp already
[08:51:21] <CaptHindsight> you can modify the source if you wanted to add something non-linear
[08:51:29] <pcw_home> just hang it on the PID output
[08:51:38] <t12> awesome
[08:52:19] <t12> the mitsu encoder support ever go anywhere
[08:52:24] <pcw_home> theres a comp for non-linear stuff also
[08:52:27] <t12> finally getting to messing with this mitsu servo on spindle
[08:52:37] <t12> with the real controller, then want to swap over to 8i20
[08:52:43] <t12> once i get my electronics together
[08:53:29] <pcw_home> theres no hm2 support for it (I dont have one)
[08:54:25] <pcw_home> I still need to get Fanuc type 2 and panasonic supported
[08:56:41] <CaptHindsight> http://www.youtube.com/watch?v=TEL_GQsCnQk Incremental Sheet Forming Process
[08:57:20] <t12> if i send a motor + controller will it help?
[08:58:32] <CaptHindsight> pcw_home: looks like we finally have sane tool chains and builds for the A20 cubie2 and similar
[08:59:43] <CaptHindsight> but now Allwinner is joining Linaro and haven't release many details on the new A80
[09:02:15] <CaptHindsight> http://www.youtube.com/watch?v=csvfcE_woQU don't try this on your cheap CNC router
[09:03:01] <Lathe_newbie> why do i get "insmod error inserting '/usr/realtime-2.6.32-l22-rtai/modules/linuxcnc/hm2_pci.ko': -l Invalid Parameters
[09:03:38] <kfoltman> CaptHindsight: how does that work?
[09:03:59] <kfoltman> milling? bending?
[09:04:49] <Lathe_newbie> ists on 10.04 2.6 pre
[09:07:49] <CaptHindsight> kfoltman: bending over a very small area at a time
[09:08:12] <syyl_ws> there are even mechanical forming tools for big milling machines availible, CaptHindsight
[09:08:21] <CaptHindsight> over the ball at the end of the tip
[09:08:24] <syyl_ws> like miniature jackhammers, air or cooleantdriven
[09:08:50] <syyl_ws> for coldforging/finishing in moldmaking
[09:09:02] <kfoltman> speaking of cheap, crappy CNC routers - http://i.imgur.com/ZB9W9RS.jpg first attempt at a cutout
[09:09:14] <kfoltman> (it's not even fully CNC, Z axis is still manual)
[09:10:10] <syyl_ws> speaking of router, did some steel on ours at work ;)
[09:10:11] <syyl_ws> https://dl.dropboxusercontent.com/u/24396704/QMTL2/IMAG0494_BURST002.jpg
[09:10:34] <kfoltman> niiice
[09:10:46] <syyl_ws> it looks rectangular, kfoltman
[09:10:50] <syyl_ws> thats a good sign ;)
[09:11:03] <kfoltman> syyl_ws: indeed :)
[09:11:26] <syyl_ws> https://dl.dropboxusercontent.com/u/24396704/QMTL2/IMAG0495.jpg
[09:11:43] <syyl_ws> wrong machine for the job, but git er done ;)
[09:13:35] <CaptHindsight> good enough for a once in a while
[09:13:47] <syyl_ws> thats for sure ;)
[09:14:12] <syyl_ws> the big vmcs where busy
[09:14:14] <Lathe_newbie> http://pastebin.com/FwCXX0Qx
[09:14:18] <Lathe_newbie> this is what i get
[09:15:05] <CaptHindsight> Debug file information:
[09:15:06] <CaptHindsight> insmod: error inserting '/usr/realtime-2.6.32-122-rtai/modules/linuxcnc/hm2_pci.ko': -1 Invalid parameters
[09:15:47] <CaptHindsight> Lathe_newbie: is this a stock install?
[09:16:07] <Lathe_newbie> CaptHindsight: new install just updated to 2.6
[09:16:10] <Lathe_newbie> but why this
[09:16:11] <Lathe_newbie> hm2/hm2_5i25.0: config.num_encoders=3, but only 2 are available, not loading driver
[09:16:20] <Lathe_newbie> i think, this is the problem
[09:16:56] <CaptHindsight> have to dig into it
[09:17:48] <CaptHindsight> Lathe_newbie: that was your only change from 2.5.x to 2.6?
[09:18:04] <Lathe_newbie> CaptHindsight: it was
[09:18:12] <Lathe_newbie> but was first run after flashing the 5i25
[09:18:17] <pcw_home> IDROM error of some kind
[09:18:42] <Lathe_newbie> pcw_home: think i should repower the 5i25 completly, not just reboot the computer?
[09:18:56] <CaptHindsight> haven't yet?
[09:19:01] <pcw_home> Yes you must power cycle
[09:19:08] <Lathe_newbie> CaptHindsight: just rebootet
[09:19:30] <Lathe_newbie> but have seen now, that i have to complete recycle, thought that this is done over the pci reset signal
[09:19:36] <CaptHindsight> 1) Did you turn it On and Off yet?
[09:19:46] <Lathe_newbie> no, but now i did and it works^^
[09:20:09] <pcw_home> the FPGA is only loaded on power cycle
[09:20:20] <Lathe_newbie> yes, this i have foun
[09:20:26] <Lathe_newbie> pcw_home: other question to you,
[09:20:40] <Lathe_newbie> are there any differets between encoder and qcount in the xml file?
[09:20:49] <CaptHindsight> http://www.youtube.com/watch?v=nn2FB1P_Mn8&feature=kp :)
[09:20:52] <Lathe_newbie> i had to change qcount to encoder that i can use it on pncconf
[09:23:56] <XXCoder> Just read about that metal bender. amazing.
[09:25:00] <SpeedEvil> http://www.ebay.co.uk/itm/LCD-DIGITAL-VERNIER-CARBON-FIBER-COMPOSITE-CALIPER-MICROMETER-GUAGE-6INCH-150MM-/330778854671?pt=UK_Measuring_Tools_Levels&hash=item4d03f4c50f
[09:25:04] <XXCoder> CaptHindsight: wonder if it would replace some uses for cnc. cheaper for one
[09:25:14] <SpeedEvil> Do you think this is likely to have any actual carbon in it? :)
[09:25:26] <SpeedEvil> On a related matter.
[09:25:32] <XXCoder> SpeedEvil: yeah. someone must have breathed co2 on it
[09:27:13] <CaptHindsight> it doesn't say how much actual carbon is in it
[09:28:10] <pcw_home> I can change "qcount" to "encoder" in my utility but this is a Mickey mouse way to do this
[09:28:45] <CaptHindsight> CARBON FIBER COMPOSITE can be 1% chopped carbon powder
[09:28:59] <XXCoder> found amazon versons http://www.amazon.com/NEEWER%C2%AE6-Composite-Vernier-Digital-Electronic/dp/B00H1KJ9TK/ref=pd_sim_sbs_hi_6?ie=UTF8&refRID=0PTJ4C5P37EP9GANTNFH
[09:31:07] <CaptHindsight> for that price it's low carbon resin, probably not an epoxy either
[09:31:48] <SpeedEvil> I was thinking of using it for a crappy DRO for my tablesaw
[09:31:59] <CaptHindsight> won't rust
[09:32:17] <CaptHindsight> looks like a good fit for that
[09:32:36] <archivist> the toy digital verniers often have a timed shutdowm making them useless for that job
[09:32:38] <CaptHindsight> more than accurate enough
[09:33:12] <XXCoder> CaptHindsight: pay few dollars more and teres better ones
[09:33:30] <XXCoder> still cheap but more reviews saying its workable and good
[09:33:45] <XXCoder> chances is its less shitty
[09:33:47] <SpeedEvil> http://www.amazon.com/dp/B0029XQM9Y/ref=biss_dp_t_asn
[09:33:53] <SpeedEvil> Probably less shitty
[09:33:54] <archivist> make sure they dont shutdown
[09:33:56] <CaptHindsight> how accurate are cuts on a table saw?
[09:34:05] <syyl_ws> 2-3/10mm?
[09:34:24] <syyl_ws> at least on our big felder table saw at work
[09:34:26] <SpeedEvil> CaptHindsight: +-0.5mm easily - done right
[09:34:29] <syyl_ws> for aluminum
[09:34:35] <XXCoder> CaptHindsight: example http://www.amazon.com/NEEWER%C2%AE6-Composite-Vernier-Digital-Electronic/dp/B00H1KJ9TK/ref=pd_sim_sbs_hi_6?ie=UTF8&refRID=0PTJ4C5P37EP9GANTNFH
[09:34:40] <XXCoder> oops wrong one
[09:35:04] <XXCoder> this one. http://www.amazon.com/Inch-Digital-Caliper-Extra-Battery/dp/B0002JFMIO/ref=pd_sim_sbs_hi_1?ie=UTF8&refRID=0NZNPGEG88ESG9Z8MRJQ
[09:35:09] <SpeedEvil> http://hackaday.com/2010/12/15/reading-a-digital-caliper-with-a-microcontroller/ is also sort-of-interesting
[09:35:16] <XXCoder> definitely not carbon though
[09:36:17] <CaptHindsight> accuracy better than +/- 1mm!
[09:36:24] <CaptHindsight> guaranteed!
[09:37:12] <XXCoder> lol WTF http://www.amazon.com/Digital-Solar-Cpliper-Vernier-Micrometer/dp/B00C1BK7YK/ref=sr_1_9?s=hi&ie=UTF8&qid=1402755520
[09:37:28] <XXCoder> nice never need battery but then...
[09:38:01] <XXCoder> that one accuracy sucks at 0.2 mm
[09:38:02] <CaptHindsight> like the calculators
[09:38:41] <XXCoder> it comes with nonrechargable battery. its bullshit solar
[09:40:23] <CaptHindsight> coal fired steam
[09:41:03] <SpeedEvil> http://www.msh-tools.com/DRO/overview.html hmm
[09:41:22] <XXCoder> I see aspire one
[09:41:25] <XXCoder> I have one lol
[09:41:30] <XXCoder> love it
[09:41:43] <CaptHindsight> I have one as well
[09:41:55] <XXCoder> windows or linux version?
[09:41:58] <CaptHindsight> atom or APU?
[09:42:12] <XXCoder> mine is pre-atom
[09:42:13] <CaptHindsight> win7 and fedora20
[09:42:45] <CaptHindsight> I bumped it to 8GB ddr3 and a 1TB drive
[09:42:51] <XXCoder> there is lots aspire ones version but mine is the first and archtype - linux version
[09:43:01] <XXCoder> 8 gb ssd lol first of its kind too
[09:43:13] <XXCoder> first public sale laptops with ssd
[09:43:40] <CaptHindsight> with a travel battery I get >12 hours
[09:44:15] <XXCoder> mine used to do that till I damaged battery :( I get around 10 hours after I recovered it from zero % point for months
[09:44:18] <CaptHindsight> good for long flights in coach
[09:46:26] <CaptHindsight> the mini-pcie slot lets you swap wifi/wimax/bt modules
[09:46:52] <XXCoder> heh dunno if I have. I think it does though
[09:47:24] <XXCoder> if I want to upgrade it with more than 8 gb hard drive I'd have to find compitiable model which probably is impossible now?
[09:47:45] <CaptHindsight> 2.5" IIRC
[09:48:03] <XXCoder> thats solid state?
[09:48:08] <CaptHindsight> and SATA
[09:48:18] <CaptHindsight> was in mine
[09:49:22] <CaptHindsight> http://i33.tinypic.com/rblh1h.jpg
[09:50:10] <XXCoder> yours was orginially windows? I know windows has different case design because hard drive is larger than ssd
[09:50:13] <CaptHindsight> http://regmedia.co.uk/2008/07/23/jkk_acer_2.jpg does your have this? compact flash?
[09:50:45] <XXCoder> didnt open and see lol nbut probably
[09:50:54] <CaptHindsight> yeah, was some win7 version that came right off and replaced by win7 pro and linux
[09:51:20] <XXCoder> I replaced some crappy linux with ubuntu
[09:51:28] <XXCoder> was great version of ubuntu
[09:51:47] <CaptHindsight> CF cards are up to 256GB IIRC
[09:51:47] <XXCoder> couple strange hacks to get wifi and blackberry tethering to work
[09:52:30] <CaptHindsight> mine has a 2.5" sata HD, can be SSD
[09:53:11] <XXCoder> http://www.jkkmobile.com/2008/07/how-to-update-acer-aspire-ones-ssd.html
[09:53:26] <XXCoder> its definitely not compact flash but definitely swappable
[09:55:24] <XXCoder> oh misread. it is.
[09:56:43] <CaptHindsight> it's time for me to replace it
[09:56:49] <CaptHindsight> not sure with what yet
[09:56:59] <XXCoder> honestly 8 gb is plenty lol
[09:57:36] <CaptHindsight> I mostly use it for backup on the road
[09:57:59] <XXCoder> my AOA now has android on it. just for kicks
[09:58:36] <CaptHindsight> I'd like a bigger display with the long life on battery
[09:59:07] <CaptHindsight> and x86 transformer, so tablet + keyboard
[10:00:07] <CaptHindsight> a large unfolding screen would also be nice
[10:00:11] <XXCoder> get a tiny pc stick and 50+" hdmi tv ;)
[10:00:18] <XXCoder> and of course giant ass battery
[10:00:26] <CaptHindsight> too big for carry-on
[10:00:30] * kfoltman batters XXCoder's ass
[10:00:41] <XXCoder> hey my batteries!
[10:00:58] <XXCoder> dammit guy stole it
[10:02:05] <CaptHindsight> most hotels I stay in have large monitors with ports to plug into
[10:02:29] <XXCoder> yeah pc stick would do it
[10:02:44] <XXCoder> I know someone that just use raspberry pi as his main computer
[10:02:58] <CaptHindsight> so i still carry my phone, notebook and a tablet
[10:03:28] <kfoltman> "How many personal computers do you carry on a daily basis?"
[10:03:57] <XXCoder> me: one, sometimes two
[10:04:10] <XXCoder> typically my phone and my nook simple touch.
[10:04:11] <CaptHindsight> not sure what the limit is but I've gotten some surprised faces before xray placing several devices in bins
[10:04:14] <kfoltman> apparently, I think the reasonable upper limit is 4
[10:04:43] <kfoltman> or 5 (a douchewatch)
[10:04:48] <XXCoder> what if I was some tiny pc device saleman with entire case? ;)
[10:04:52] <kfoltman> maybe 6 (google glass)
[10:05:25] <CaptHindsight> I've taken small cnc machines carry-on
[10:05:32] <kfoltman> CaptHindsight: :O
[10:05:54] <CaptHindsight> also complete desktop itx-case PC's in my roll-on
[10:06:39] <CaptHindsight> if it fits in the roll-on, sometimes it's even over weight so I'm sure to lift it myself
[10:06:43] <archivist> I had a VNA display on my flight back once
[10:07:15] <CaptHindsight> or an oscilloscope as a carry on
[10:07:46] <XXCoder> heh and weirdest device I bought in plane was zvrs z340
[10:07:50] <XXCoder> its videophone
[10:09:17] <CaptHindsight> last trip back from NYC I had 2 ballscrew linear positioners, steppers and drivers + power supplies in my roll-on
[10:09:34] <CaptHindsight> Xray didn't even blink
[10:09:51] <XXCoder> ballscrew flak bomb :P
[10:10:15] <CaptHindsight> only 8-12" long
[10:10:28] <XXCoder> its all pointless, someone figured how to make weapons using pure inside secure area stores stuff
[10:10:39] <XXCoder> bomb, "gun"
[10:11:17] <CaptHindsight> sssshhhh
[10:11:28] <CaptHindsight> extrusions are here, bbl
[10:11:54] <XXCoder> bah I want 8020s lol
[11:01:21] <XXCoder> http://boingboing.net/2014/06/10/vermeers-paintings-might-be.html interesting
[11:01:25] <XXCoder> and yes there is some cnc lol
[11:01:59] <XXCoder> cnc parts is definitely interesting
[11:03:17] <syyl_ws> i want a fadal too :D
[11:04:03] <syyl_ws> funny enough, there are a lot of fadals used for woodwork
[11:11:31] <XXCoder> whats fadal?
[11:11:57] <toastyde1th> fadal is a brand of machine + control
[11:14:48] <XXCoder> ahh cool
[11:46:43] <CaptHindsight> XXCoder: "The detailed inventory of the artist's belongings drawn up after his death does not include a camera obscura or any similar device" yet it sure looks that way
[11:47:12] <XXCoder> yeah thats why he said "its proven possible method" not "it IS the way he did it"
[11:48:03] <CaptHindsight> his work sat for years
[11:52:29] <CaptHindsight> http://media.boingboing.net/wp-content/uploads/2014/06/IMG_0335-680x510.jpg gap bed wood lathe
[11:52:42] <XXCoder> yeah
[11:52:46] <XXCoder> risky lol
[11:52:50] <CaptHindsight> it wasn't long enough so her took a bandsaw to it
[11:52:58] <archivist> not risky, its clamped
[11:52:59] <XXCoder> yeah
[11:52:59] <CaptHindsight> her/he
[11:54:34] <CaptHindsight> I worked on printing copies of Vermeers with inkjet and then coating them with a clear brush stroked acrylic to make them look hand painted
[11:54:53] <XXCoder> nice lol
[11:55:08] <CaptHindsight> he'e been getting attention the past 10 years, two movies already
[11:56:48] <Loetmichel> CaptHindsight: whre is the problem?
[11:56:58] <Loetmichel> would have totally done that to a wood lathe also
[11:57:49] <syyl_ws> you would cut your bandsaw in half?
[11:57:51] <Loetmichel> but i would have made a fitting insert that could be bolted to bot ends, so the "ways" are more or less usable again across the wole new length
[11:57:57] <syyl_ws> *wood lathe
[11:58:04] <Loetmichel> a bit like enlarging a ship
[11:58:14] <CaptHindsight> I point out the fun and exciting as well, not just engineering failures :)
[11:58:22] <syyl_ws> yay
[11:58:47] <syyl_ws> no more cheesemill-ranting today? :/
[11:58:56] <Loetmichel> syyl_ws: if i need a bigger late: sure, why not?
[11:58:57] <XXCoder> harbor feight lathe is less than 100 buck
[12:00:02] <Loetmichel> XXCoder: and still too small i would presume ;)
[12:00:12] <XXCoder> probably its 3 feet wide?
[12:00:16] <Loetmichel> tim had a lathe he knew would work
[12:00:18] <XXCoder> long rather
[12:00:26] <Loetmichel> it just was a bit to short
[12:00:44] <Loetmichel> where is the problem in using a bandsaw to solve that?
[12:00:59] <Loetmichel> http://media.boingboing.net/wp-content/uploads/2014/06/IMG_0335-680x510.jpg
[12:01:06] <Loetmichel> look at the pic, there is noting unsafe
[12:01:24] <Loetmichel> even with the middle part missing
[12:01:27] <XXCoder> interesting I see tool changer
[12:01:49] <Loetmichel> (which i would have filled with a matching aluminium block so tha ways are intact again?
[12:01:52] <CaptHindsight> I would have just made the room smaller, so to each his own
[12:01:55] <Loetmichel> -?+)
[12:01:56] <XXCoder> I guess guy knew how to carefully align tailstock with chuck
[12:02:16] <XXCoder> CaptHindsight: or just different scene
[12:02:19] <XXCoder> dunno
[12:02:52] <Loetmichel> that is not so critical in a wood lathe, the railstock only holds a rotating cone so a bit of misalignment doesent do any harm
[12:02:58] <Loetmichel> -r+t
[12:05:14] <CaptHindsight> he could have made the legs in two parts, saving wear on his bandsaw blade
[12:05:50] <XXCoder> thats possible too. just close enough to screw parts together and sand differences
[12:06:06] <IchGuckLive> hi all
[12:06:11] <XXCoder> hey
[12:06:29] <XXCoder> we are talking about lathe cut in half and modified
[12:06:42] <XXCoder> http://boingboing.net/2014/06/10/vermeers-paintings-might-be.html
[12:07:00] <IchGuckLive> mashine cut in halv is a bad idee
[12:07:56] <IchGuckLive> ssi: ?
[12:09:40] <IchGuckLive> XXCoder: some motorised movement till now
[12:11:33] <XXCoder> ich did you see my cnc router plans?
[12:12:19] <IchGuckLive> you start on to high values for your valet
[12:29:31] <IchGuckLive> today it has been a cold day here in germany complained to the laste week with desert like temps
[12:30:26] <XXCoder> its been nice and cool here
[12:30:28] <XXCoder> might even rain
[12:31:21] <IchGuckLive> we bearly need rain here but no drop in radar view
[12:33:31] <ssi> IchGuckLive: hm?
[12:34:38] <Loetmichel> i think he meant dearly
[12:35:06] <ssi> Loetmichel: questioning cause he was calling me 30m ago :)
[12:35:21] <Loetmichel> and compared, not complained...
[12:35:42] <Loetmichel> IchGuckLive: you should work on your english a bit ;.)
[12:35:56] <Loetmichel> ssi: ah! ;-)
[12:36:54] <IchGuckLive> a little over 2month to go for me then im off the system no more english at all
[12:37:01] <ssi> haha
[12:38:19] <Loetmichel> IchGuckLive: then you go to a remote location somewhere or jump a bridge?
[12:40:18] <IchGuckLive> oh we got a high brigh her to be build Hochmoselübergang
[12:40:36] <IchGuckLive> remote location its cald the local outback
[12:40:55] <Loetmichel> outback in germany?
[12:40:57] <Loetmichel> where?
[12:41:13] <archivist> prison
[12:41:30] <Loetmichel> hmm, THAT is entirely possible
[12:41:38] <IchGuckLive> not far i can see the sateölite post from here they made to stay in some civilisation
[12:42:11] <IchGuckLive> no its a short depth valey where the sun is not often visible
[12:44:29] <Jymmm> ssi: Where unicode comes in nice is symbols... 12KΩ, Teflon™, etc, but ASCII still RULES =)
[12:44:47] <ssi> haha we're still on that?
[12:44:47] <IchGuckLive> no postsrvice no phone no tv ,no city water, no drains .....
[12:44:59] <Jymmm> ssi: 75˚F
[12:45:24] <Jymmm> ssi: Nah, I just needed to lookup the (TM) symbol for something else is all =)
[12:45:33] <ssi> hahaha
[12:46:07] <Jymmm> Teflon(tm) = trade name, PTFE = generic name
[12:46:28] <IchGuckLive> PolyTetraFlurEthylen
[12:46:48] <CaptHindsight> slippery stuff = street name
[12:46:49] <IchGuckLive> Ethan ;-)
[12:47:08] <Jymmm> CaptHindsight: and toxic > 500F
[12:47:20] <ssi> ݯ
[12:47:22] <ssi> does that work?
[12:47:22] <archivist> teflon...see Don
[12:47:29] <archivist> no
[12:47:29] <Jymmm> ssi: arabic symbol
[12:47:32] <ssi> ۩
[12:47:33] <ssi> ok cool
[12:47:36] <IchGuckLive> Jymmm: i think near everything gets toxic >500
[12:47:43] <ssi> so those are under U+800
[12:47:46] <ssi> so they're two bytes in utf-8
[12:47:57] <Jymmm> IchGuckLive: PTFE outgasses at > 500F
[12:48:00] <ssi>
[12:48:13] <ssi> that one is over U+800 but under U+1000
[12:48:23] <CaptHindsight> perfect for cookware
[12:48:41] <Jymmm> CaptHindsight: Yep, wanna guess what temp bacon frys at?
[12:48:48] <Jymmm> CaptHindsight: 550F =)
[12:49:08] <ssi> ⣿ braille chars lul
[12:49:20] <CaptHindsight> bacon fat = health food, so it cancels out any byproducts from the PTFE
[12:49:28] <Jymmm> hahaha
[12:49:38] <ssi> ⿕ radical flute
[12:49:55] <ssi> I think this supports everything up to U+FFFF
[12:49:56] <ssi> but not above
[12:50:35] <CaptHindsight> does Gimp still have the ASCII converter plug-in?
[12:51:07] <ssi>
[12:51:18] <ssi> that one is U+FFE5
[12:51:38] <ssi>
[12:51:46] <IchGuckLive> ok im iff Biggest fault here has been making near everyhouse a BBQ oven on the plasmas now everyday party ;-)
[12:52:08] <ssi> haha ok ich that didn't parse at all :D
[12:52:49] <Jymmm> ssi: I think he said "your momma", but I could be mistaken.
[12:52:56] <ssi> sounds about right
[12:53:02] <CaptHindsight> BBQ on the patio
[12:53:05] <archivist> I wonder if he is as incoherent in german
[12:53:11] <ssi> ahahaha
[12:53:14] <Jymmm> lol
[12:53:43] <ssi> I think I might have an easier time piecing together his german
[12:53:51] <ssi> and I know very very little german
[12:54:30] <CaptHindsight> best guess "the problem here is that every house has a BBQ on their patio so there's a party everyday"
[12:54:44] <ssi> how did plasmas get into it?
[12:55:07] <CaptHindsight> or plaza
[12:55:13] <ssi> ahh
[12:55:15] <CaptHindsight> plaza = patio
[12:55:47] <CaptHindsight> BBQ does use plasma energy
[12:55:59] <CaptHindsight> so I could be wrong
[12:56:03] <ssi> true :P
[13:03:01] <Jymmm> I've heard of chinglish, but dutlish?
[13:04:08] <ssi> dammit I can't stop thinking about boats :(
[13:04:21] <Jymmm> ssi: DAS BOOT
[13:04:26] <archivist> add floats to the plane
[13:05:34] <ssi> no we've been through this! D:
[13:09:26] <Lathe_newbie> http://imagebin.org/313673 something like this should work?
[13:16:13] <archivist> imagebin is an attack page and banned
[13:16:32] <CaptHindsight> I didn't get the warning today
[13:16:41] <archivist> I just did
[13:17:10] <archivist> I suppose it takes time to spread good/bad news
[13:17:12] <CaptHindsight> I started using imagebin.ca
[13:17:46] <archivist> I self host http://www.archivist.info/addedsql.jpg
[13:19:41] <CaptHindsight> the images I generally post are only for short term pleasure, like a child's balloon or skywriting
[13:20:21] <Lathe_newbie> archivist: http://abload.de/img/drivervyu7w.png better?
[13:20:48] <CaptHindsight> not until google caches it :)
[13:20:55] <Lathe_newbie> any idea, why this does not work?
[13:21:44] <CaptHindsight> so your UP and DOWN inputs sink?
[13:21:49] <CaptHindsight> so/do
[13:21:51] <archivist> I would use a meter/scope to see why
[13:22:20] <Lathe_newbie> CaptHindsight: yes, they should, cause default is 1 on output of the mesa card
[13:23:03] <Lathe_newbie> when i turn the motor axis by hand... it incremets or decrements the actual position in linuxcnc, but it does not work against my manual rotation
[13:23:32] <archivist> is it a dc motor
[13:24:09] <Lathe_newbie> yes it is
[13:24:34] <archivist> I do not expect to see outputs shorted together on an L298 normally
[13:25:04] <Lathe_newbie> archivist: but i think, it should give pwm for holding the actual position?
[13:25:27] <Lathe_newbie> prehaps pwm frequency to high?
[13:26:18] <archivist> scope it
[13:27:15] <Lathe_newbie> dont have a scope
[13:28:06] <CaptHindsight> I haven't played with this driver, Can you ground Sense?
[13:28:31] <Lathe_newbie> i dont sense
[13:30:22] <CaptHindsight> how low does UP and DOWN go?
[13:30:57] <CaptHindsight> check the values of R3 and R4 are you getting output on pin6?
[13:32:07] <CaptHindsight> what are the values of R1 and R2?
[13:32:51] <archivist> you have two bridges but are shorting them, are you using a recommended circuit?
[13:33:20] <CaptHindsight> the data sheet says you can parallel outputs for greater current
[13:33:58] <pcw_home> also putting a halmeter on the the PWM value pin should help
[13:34:44] <CaptHindsight> For higher currents, outputs can be paralleled. Take care to parallel channel 1 with channel 4 and channel 2 with channel 3.
[13:35:17] <CaptHindsight> Lathe_newbie: you have them paralleled wrong
[13:35:35] <archivist> the idea of the bridge is to avoid switching both on, look at fig 7 in the data sheet how to parallel you are doing it wrong
[13:36:31] <CaptHindsight> and with sense grounded did you kill the L298?
[13:36:40] <Lathe_newbie> r1 and r2 are 10k
[13:36:50] <CaptHindsight> since the outputs are shorted
[13:37:15] <Lathe_newbie> CaptHindsight: no, i just dont do current sensing
[13:37:38] <CaptHindsight> OUT1 should be on pins 2 and 14, and Out2 should be pins 3 and 13
[13:37:40] <archivist> use the current sense too so you dont kill the spare one you should have bought
[13:38:39] <CaptHindsight> also your inputs to the L298b are wrong
[13:39:08] <CaptHindsight> http://www.st.com/st-web-ui/static/active/en/resource/technical/document/datasheet/CD00000240.pdf page 7
[13:39:10] <accuartisans> pcw_home: hey are you online?
[13:39:56] <CaptHindsight> Input1 should be pins 5 and 12, Input2 should be pins 7 and 10
[13:40:34] <CaptHindsight> Lathe_newbie: fix those and you should be good
[13:41:29] <Lathe_newbie> CaptHindsight: shure that it does not work as it is?
[13:42:03] <CaptHindsight> I hate when they have something so critical not in BOLD
[13:42:15] <CaptHindsight> Lathe_newbie: read the data sheet ^^
[13:42:23] <pcw_home> accuartisans: yes
[13:42:34] <archivist> Lathe_newbie, it is plainly put that you do it the other way
[13:42:40] <CaptHindsight> Lathe_newbie: " For higher currents, outputs can be paralleled. Take care to parallel channel 1 with channel 4 and channel 2 with channel 3."
[13:42:42] <Lathe_newbie> mhm have seen
[13:43:29] <Lathe_newbie> or i do it with gate drivers and mosfets... just wanted to do a quick test...
[13:44:08] <CaptHindsight> knife switches and fast hands
[13:45:12] <archivist> hmm, I got the knife switches...
[13:45:32] <archivist> and the slate panel they are mounted on
[13:45:45] <accuartisans> pcw_home: I think I have a good build now with my 3.14.4 kernel, xenomai 2.6.3 and the right branch of linuxcnc for my 7i80 - 7177 setup, I'm looking at a default mesa servo ini and hal, but i'm a little confused. any chance you have a ini and hal you can share with me?
[13:46:28] <pcw_home> also if you connect FPGA output pins to OPTOs with anodes at 5V you need to either enable open drain mode
[13:46:29] <pcw_home> or use a series diode so the 3.3V high output of the FPGA doesn't slightly turn on the OPTO LED when the output is high
[13:46:53] <accuartisans> pcw_home: just to get me started please.
[13:47:28] <Lathe_newbie> pcw_home: so i should connect the outputs other way?
[13:47:58] <pcw_home> no, either use open drain mode or use a diode
[13:48:38] <pcw_home> for the L298 with no enable it probably doesn't matter
[13:49:03] <pcw_home> for a real machine with an enable its critical
[13:49:14] <Lathe_newbie> will build a new drive with ir21844 and mosfets
[13:49:32] <pcw_home> accuartisans: I dont have any real experience with Xenomai
[13:50:29] <pcw_home> all my recent testing is with Preemt-RT
[13:51:21] <accuartisans> pcw_home: that's no problem, just need a generic 3 axis ini, hal for the 7i80/7i77, i don't think the xenomai make a difference for that does it?
[13:51:41] <accuartisans> just to get me up and started
[13:52:03] <CaptHindsight> accuartisans: can you post you kernel config?
[13:52:07] <CaptHindsight> please
[13:52:14] <pcw_home> the ubc3-7i80 source needs to have been built for xenomai
[13:52:40] <pcw_home> (and you need a RT-Net compatible MAC)
[13:52:44] <accuartisans> pcw_home: yep, that's the branch i'm using, ran latency as well
[13:54:51] <accuartisans> yeah, that's what's interesting, there is no script in this branch for start_net?? I did get rt-net to finally to compile with a lot of work. there are known compile issues for xenomai 2.6.x
[13:55:33] <pcw_home> does rt-ping (the 7I80) work?
[13:55:47] <accuartisans> capthindsight: you want the .config file that i built th kernel on?
[13:56:03] <CaptHindsight> accuartisans: yes, please
[13:57:00] <accuartisans> pcw_home: haven't tried that yet, so is the command rt-ping
[13:57:11] <pcw_home> yeah
[13:59:37] <pcw_home> http://gnipsel.com/linuxcnc/configs/7i77.html
[13:59:39] <pcw_home> has a generic 7i77 config, you will need to change the board name in the ini file
[13:59:40] <pcw_home> and
[13:59:42] <pcw_home> DRIVER=hm2_eth board_ip="" board_mac="00:60:1B:10:XX:XX"
[14:00:57] <accuartisans> pcw_home:perfect, working on getting the .config ...
[14:01:05] <pcw_home> (the XX:XX being your 7I80's MAC address, this should not be needed as the driver should poke at the arp tables)
[14:01:23] <accuartisans> working between to machines:)
[14:02:32] <CaptHindsight> accuartisans: are you using Ubuntu 12.04 or?
[14:03:05] <pcw_home> actually not sure about RT-Net it has some static ARP stuff.
[14:03:06] <pcw_home> Preemt-RT definitely needs a static ARP entry so it does not periodically do ARP refreshes
[14:03:49] <accuartisans> capthindsight: 14.4
[14:04:15] <CaptHindsight> great, working on 14.04 as well
[14:04:32] <accuartisans> sorry, ment 14.04
[14:05:06] <CaptHindsight> accuartisans: did you build packages for linuxcnc?
[14:06:51] <accuartisans> capthindsight: yes, newbie for this irc stuff, how do i upload a file?
[14:07:01] <CaptHindsight> I just did a fresh install of 14.04 earlier today
[14:07:08] <CaptHindsight> accuartisans: use pastebin
[14:07:17] <CaptHindsight> pastebin.ca
[14:07:41] <CaptHindsight> cut and paste and the post the link it gives you
[14:08:30] <CaptHindsight> I'm using 3.4.55 RTAI right now
[14:08:49] <Jymmm> Just FYI.... If you upgrade FF, be sure to bookmark "open tabs" before installing/editing add-ons. FSCKING FF
[14:10:07] <accuartisans> capthindsight: on 14.04? if so, loved to know how you did that?
[14:11:57] <CaptHindsight> haven't built Linuxcnc on it yet
[14:12:30] <accuartisans> capthindsight: pastebin says it only will take 150K, file is to big, i'll have to break it up, hold on.
[14:13:08] <Jymmm> http://codepad.org/
[14:13:29] <CaptHindsight> accuartisans: ^^
[14:13:34] <accuartisans> capthindsight:but you have RTAI running on ubuntu 14.04?
[14:14:20] <CaptHindsight> accuartisans: I used sebs debs and linux-image-3.4.55-rtai-2 rtai-modules-3.4.55-rtai-2
[14:15:25] <accuartisans> capthindsight: http://codepad.org/gtTKcWyU
[14:16:30] <accuartisans> capthindsight: ok, that would likely not work for this motherboard as it is the new bat trail chipset
[14:16:56] <accuartisans> capthindsight:that's the bad part of using such a new motherboard
[14:17:20] <CaptHindsight> IIRC the graphics drivers need 3.10 or higher
[14:17:34] <CaptHindsight> but it might run
[14:17:55] <CaptHindsight> only with software rendering
[14:19:00] <accuartisans> capthindsight: yes it has to do with the graphics drivers, but i did not know how to integrate the drivers into an older kernel?? what's IIRC?
[14:19:19] <CaptHindsight> if i recall correctly
[14:19:29] <Jymmm> iirc = if I remember correctly
[14:19:34] <accuartisans> :)
[14:19:40] <accuartisans> gotcha
[14:20:32] <accuartisans> capthindsight: i tried ubuntu 12.x and the graphics were terrible
[14:20:49] <accuartisans> capthindsight:were you able to see the config?
[14:21:16] <CaptHindsight> accuartisans: yes, got it, thanks again
[14:21:33] <CaptHindsight> accuartisans: did you build Linuxcnc from scratch?
[14:22:56] <accuartisans> capthindsight: yes from ucb3-7i80 branch
[14:23:37] <CaptHindsight> I want to test it for multitouch and onscreen keyboard
[14:23:48] <accuartisans> capthindsight: you would not believe the hours i have into getting kernel 3.14.4 and xenomai 2.6.3 together!
[14:23:54] <CaptHindsight> heh
[14:24:15] <CaptHindsight> well we spent months on RTAI :)
[14:24:38] <CaptHindsight> bumping it up from 2.6 to 3.4
[14:25:01] <pcw_home> Preemt-RT is a 10 minute affair...
[14:25:13] <CaptHindsight> waiting for some fixes to bump it to 3.14 now
[14:25:18] <CaptHindsight> yeah :)
[14:25:56] <CaptHindsight> and Preemt_rt is fast enough for all the fpga boards
[14:25:59] <accuartisans> capthindsight: i have the image and header i can share, i had to modif 5 xenomai header files to get it to compile, i can share those as well.
[14:26:19] <CaptHindsight> anything to help us all get this going
[14:26:36] <CaptHindsight> all your work is definitely appreciated
[14:27:10] <accuartisans> pcw_home: agree!!
[14:27:18] <CaptHindsight> accuartisans: do you have time to create a howto on the linuxcnc wiki?
[14:27:41] <accuartisans> capthindsight: that's my plan
[14:27:46] <CaptHindsight> great
[14:28:37] <Lathe_newbie> like this it should work? http://abload.de/img/drive2hmogs.png
[14:28:45] <accuartisans> pcw_home: thanks for the 7i77 link, i've seen that before, just forgot about it, that should get me started.
[14:29:11] <CaptHindsight> hmm try to save $150 in fpga + stepper IO boards by spending hundreds of hours on RTAI
[14:29:39] <CaptHindsight> that's not the real goal
[14:31:23] <pcw_home> Lathe_newbie: Probably sort of marginal active low is better (either with open drain mode or a diode in series with the OPTO LED)
[14:31:43] <pcw_home> (open drain mode is set in HAL)
[14:35:27] <accuartisans> pcw_home: question what is the default bit file loaded on a 7i80?
[14:35:50] <CaptHindsight> accuartisans: do you get deja-dup-monitor warnings/errors on your 14.04?
[14:36:49] <accuartisans> capthindsight: where would i see that? in the boot up log? I don't recall any of that.
[14:37:04] <accuartisans> i can look in a minute
[14:37:15] <accuartisans> if it's in the log
[14:38:42] <CaptHindsight> accuartisans: are you using Unity?
[14:38:44] <pcw_home> accuartisans: depends on model but I would check (with mesaflash) before connecting anything
[14:39:05] <accuartisans> pcw_home:will do
[14:39:10] <accuartisans> pcw_home:thanks
[14:39:22] <accuartisans> caphindsight:yes
[14:39:34] <pcw_home> (latest mesaflash has a readhmid mode thats lists the pinout)
[14:39:36] <accuartisans> it's not in the kern.log
[14:41:19] <accuartisans> capthindsight: it's not in syslog or Xorg.0.log either
[14:43:10] <CaptHindsight> maybe it's the 3.4.55 causing it?
[14:43:30] <CaptHindsight> only have the problem when 3.4.55 is loaded
[14:43:55] <accuartisans> catphindsight: it's not in dmesg either
[14:44:15] <CaptHindsight> I just removed it
[14:44:29] <CaptHindsight> don't really want a backup monitor
[14:45:39] <accuartisans> pcw_home:btw, i have the 7i80db-25 and a 7i77
[14:48:29] <accuartisans> i'm likely going to have questions when it comes to hooking up these AMC BE25A20 drives, but i'm not ready for that:)
[14:48:43] <pcw_home> that _may_ have been shipped with a 7I77 compatible bit file but I would still check
[14:49:05] <kfoltman> what do you guys use for generating gcode?
[14:49:29] <accuartisans> pcw_home: that's what i'm guessing, but you want me to check without the 7i77 connected, correct?
[14:49:36] <jthornton> kfoltman, gedit
[14:50:23] <pcw_home> well at least before you start linuxcnc
[14:50:38] <accuartisans> pcw_home:10-4
[14:54:34] <CaptHindsight> pcw_home: using hardware stepping on the 6i25. how poor can a systems jitter be without problem?
[14:55:05] <pcw_home> umm depends on the definition of problem :-)
[14:55:39] <CaptHindsight> hm2 can't function
[14:56:10] <CaptHindsight> or really to get say 50-100Khz stepping
[14:56:14] <pcw_home> the drivers built in position control loop doesn't do well with more than say 50 usec on a a 1 KHz loop
[14:56:48] <CaptHindsight> so <50us on the 1mS thread
[14:56:58] <pcw_home> but if you use a PID-stepper config, 350 usec or so is tolerable
[14:57:12] <accuartisans> pcw_home: I remember a while back you posted on the forum that there was fix for some kind of timing issue for these new FPGA processors, how would I know if I have the current fix?
[14:57:36] <CaptHindsight> ah ok, we had issues with preempt_rt being over 90K once
[14:58:05] <pcw_home> accuartisans: update the bitfile from the mesa zip
[14:58:40] <accuartisans> pcw_home: That's what I thought I remember you saying, thanks!
[14:58:48] <pcw_home> the problem with the built in position mode loop is it trusts the thread timing more than the hardware
[14:59:13] <pcw_home> (for a hardware stepgen, the opposite is much better)
[14:59:50] <pcw_home> I have examples pf pid-stepper configs, they are easy
[15:02:14] <accuartisans> pcw_home: I assume you are saying the 7i80.zip?
[15:02:25] <pcw_home> yes
[15:03:17] <accuartisans> pcw_home: Thanks, I download it yesterday. Guys, I have some wiring to do:) Thanks for the help again!
[15:04:26] <accuartisans> I get to work on this a little, "father's day" and all:)
[15:05:03] <pcw_home> :-)
[15:10:30] <pcw_home> CaptHindsight: so MHz step rates are no issue with 350 or so usec jitter
[15:10:32] <pcw_home> since the jitter just gets low pass filtered away by the PID loop
[15:10:33] <pcw_home> (99.9 percent of the control is just velocity feed forward)
[15:10:35] <pcw_home> and the remaining 0.1% is just a slow feedback loop to correct for
[15:10:36] <pcw_home> minor timebase differences, reversal delays etc
[15:12:06] <pcw_home> the BBB/PRU machine kit people moved to a PID step system in HAL already
[15:21:07] <Jymmm> Very cool... http://www.viralnova.com/king-of-men/?utm_source=newsletter&utm_medium=email&utm_campaign=aweber
[15:22:34] <CaptHindsight> 3.4.55 RTAI on 14.04 was zippy on an older PhoenomII 780 mainboard, it's a real dog on the E350M1
[15:23:12] <CaptHindsight> looks like 12.04 + 3.4.55 RTAI until RTAI gets fixed for newer kernels
[15:24:34] <Loetmichel> Jymmm: "balls of steel"
[15:26:38] <accuartisans> capthindsight: is the e350m1 a amd embedded board?
[15:28:48] <accuartisans> capthindsight: if so, i had real problems with the amd 350, so i went a gigabyte J1800N-D2H, so far I am real impressed with it
[15:29:14] <pcw_home> Yeah the Baytrail chips are very nice
[15:29:29] <accuartisans> capthindsight: this has the bay trail embedded processor
[15:30:18] <accuartisans> capthindsight: ^^pcw_home put me on the trail for it:)
[15:30:34] <accuartisans> capthindsight: i'm sold on it
[15:31:55] <CaptHindsight> accuartisans: I don't use Intel unless forced
[15:32:55] <CaptHindsight> 14.04 + preemept_rt and 6i25 also works fine
[15:33:05] <accuartisans> capthindsight: agreeded, i don't either and hate not for many many years, but this forced me to!
[15:33:27] <accuartisans> have not
[15:33:59] <CaptHindsight> haven't had to in 10 years
[15:35:00] <accuartisans> capthindsight: when pcw_homw posted some latency numbers recently and i was struggling with the amd 350, i was like dam!
[15:35:34] <CaptHindsight> I have the E350M1 running with lower 25uS scores than any other board
[15:35:38] <accuartisans> capthindsight: This is a first for since a 286!
[15:35:52] <CaptHindsight> not sure what problem you had
[15:36:01] <accuartisans> capthindsight: is that a gigabyte?
[15:36:21] <CaptHindsight> asrock E350M1 with factory EFI
[15:36:41] <accuartisans> capthindsight: unfortunately, i had a biostar
[15:36:55] <CaptHindsight> biostar has lots of BIOS issues
[15:36:56] <accuartisans> capthindsight: never again
[15:37:10] <accuartisans> capthindsight: yep, lesson learned
[15:37:16] <CaptHindsight> I used to design mainboards
[15:38:09] <accuartisans> Cool! then you have a upper hand:)
[15:38:56] <CaptHindsight> the E350M1's just got difficult to find, but AMD just released new APU's at Computex to replace the old embedded
[15:39:10] <CaptHindsight> so new boards should be out shortly
[15:39:37] <CaptHindsight> using FM2 APU's and A88 chipset boards for now
[15:39:48] <accuartisans> capthindsight: what's the processor? better than the 350/450's?
[15:40:09] <accuartisans> capthindsight: Oh! now that should be nice!
[15:40:14] <CaptHindsight> if the superIO is supported on the Biostar then you could port coreboot to it
[15:40:49] <accuartisans> capthindsight: coreboot? is that a bios replacement?
[15:41:33] <accuartisans> capthindsight: wow, i'll have to look at this futher
[15:41:43] <CaptHindsight> accuartisans: yes, open source firmware replacement
[15:42:19] <CaptHindsight> but if you thought the kernel work was difficult hold on to your hats for coreboot
[15:42:55] <CaptHindsight> http://www.asrock.com/mb/AMD/FM2A88M-HD+/?cat=Specifications trying these out now, coreboot port in the works
[15:43:00] <marmite> hell yeah got a compact 5 emco cnc this week
[15:44:51] <accuartisans> capthindsight: looks like no love for biostar, that's ok, i needed a new board for my shoebox desktop machine anyways,
[15:45:18] <accuartisans> capthindsight: that's where i planned on using it anyway.
[15:45:58] <accuartisans> capthindsight: still might be worth looking into though.
[15:46:07] <accuartisans> capthindsight: coreboot that is:)
[15:47:59] <CaptHindsight> accuartisans: is this it? http://www.biostar-usa.com/app/en-us/event/a68/index.htm
[15:50:04] <accuartisans> capthindsight: yes, but version2: http://www.biostar-usa.com/app/en-us/mb/introduction.php?S_ID=618
[15:51:45] <CaptHindsight> the asrock and the gigabyte version of that work fine
[15:55:33] <accuartisans> capthindsight: yep, i should have done a little more reading on the forums before i bought that board:)
[15:56:29] <accuartisans> capthindsight: what can i say... a linuxcnc newbie mistake!
[15:57:03] <CaptHindsight> we have problems with Biostar and Linux in general
[15:57:12] <CaptHindsight> odd acpi issues
[15:58:00] <XXCoder> wow lots of name dings
[15:58:01] <accuartisans> capthindsight: i think that is where it is, usb especially!!!
[15:58:36] <CaptHindsight> and Gigabyte tends to have poor USB ESB protection
[15:58:49] <accuartisans> capthindsight: mouse would just create terible spikes
[15:59:46] <CaptHindsight> been using Asrock and ASUS boards lately
[16:00:01] <accuartisans> capthindsight: ESP protection?? is that a back flow of voltage?
[16:00:13] <CaptHindsight> static
[16:00:18] <accuartisans> gotcha
[16:00:21] <XXCoder> mouse with awful spikes http://goo.gl/UVHMnH
[16:00:50] <CaptHindsight> XXCoder: gotta watch out for those
[16:01:04] <accuartisans> XXCoder: LOL, i just had to look.
[16:01:43] <CaptHindsight> have to get back to cutting
[16:02:07] <XXCoder> acc funny because I just opened one when you said it
[16:02:12] <accuartisans> thanks again for all the help! I'm out as well.
[16:02:46] <XXCoder> ummm http://whoisscout.files.wordpress.com/2011/02/mickey-hat.jpg LOL

[16:48:00] <zeeshan|2> how the heck do i hold that in my lathe
[16:48:22] <zeeshan|2> the right end has a center mark on it which can go on the tailstock
[16:48:31] <zeeshan|2> not sure how to hold the rest
[16:49:43] <XXCoder> magic
[16:49:45] <XXCoder> easy.
[16:49:47] <XXCoder> ;)
[16:49:49] <zeeshan|2> lol
[16:50:03] <XXCoder> seriously dunno. your chuck cant fit left end eh
[16:50:08] <zeeshan|2> it can
[16:50:12] <zeeshan|2> but its a tapered suface
[16:50:14] <zeeshan|2> *surface
[16:50:17] <XXCoder> and it has no center mark? oh
[16:50:30] <zeeshan|2> hmm
[16:50:33] <zeeshan|2> i wonder if i have big ass center
[16:50:48] <Jymmm> zeeshan|2: black hole
[16:50:52] <XXCoder> shims?
[16:51:47] <zeeshan|2> http://www.ebay.ca/itm/NEW-MORSE-TAPER-MT-3-LATHE-LIVE-BULL-NOSE-PIPE-CENTER-/400717080153?pt=LH_DefaultDomain_0&hash=item5d4c996659
[16:51:49] <zeeshan|2> thats what i need
[18:27:28] <zeeshan|2> archivist: have you machined helical gears?
[19:18:39] <SpeedEvil> I did once.
[19:18:46] <SpeedEvil> But manually
[19:18:57] <SpeedEvil> So it probably doesn't count
[19:19:36] <XXCoder> zeeshan|2: figured how moubnt that thing yet?
[19:34:44] <CaptHindsight> zeeshan|2: not only that, but he wrote all the Gcode by hand :)
[19:40:03] <CaptHindsight> http://www.tenryu.com/pra.html cuts through extrusions like a hot knife through butter
[21:27:42] <Lathe_newbie> is there a possibility to enable open drain in pncconf'
[21:27:55] <Lathe_newbie> ?
