[02:23:41] <Deejay> moin
[04:36:13] <archivist> just scrolled back, microstepping on a rack and pinion....unrealistic expectations
[04:40:45] <archivist> once I automate the DTI data capture I can show graphs to show why he is seeing a stepper microstepping problem
[07:03:36] <Tom_itx> 11 F
[07:04:02] <jthornton> 30F
[07:04:34] <Tom_itx> both pages are up now
[07:04:47] <jthornton> what's the link again?
[07:05:05] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/emc/xilinx/xilinx14_install_index.php
[07:05:06] <Tom_itx> is one
[07:05:10] <ries> awallin: Small question for your you, how hard do you think it would it be to port OpenVoronoi to java? (http://www.anderswallin.net/cam/)
[07:05:53] <jthornton> looking good, your an asciidoc expert now
[07:06:02] <Tom_itx> they link each other at the top
[07:06:29] <Tom_itx> no expert, i still need sidebar menu
[07:06:56] <jthornton> I like how you spell out the OS your using
[07:08:28] <Tom_itx> i suppose i should add that to the 9.2 one
[07:08:45] <Tom_itx> err maybe i did
[07:22:03] <archivist> ries, why would you port to a slower language
[07:51:48] <ries> archivist: Because otherwise I need to compile a library on different platforms for distribution, and my requirements are not that I need to handle huge models
[07:53:54] <ries> it also doesn't have to be (a lot) slower...
[08:02:05] <jdh> oh. that.
[08:06:08] <Jymmm> Did they have residential dimmers 100 years ago?
[08:06:30] <jdh> sure, just turn the flame down.
[08:06:52] <Jymmm> They had electricity in 1910 =)
[08:06:59] <Jymmm> 1914
[08:07:05] <jdh> they had phones too
[08:07:07] <jdh> and airplanes
[08:07:16] <Jymmm> and dimmers?
[08:07:18] <archivist> they had rheostats
[08:07:28] <Jymmm> archivist: residential?
[08:13:37] <Jymmm> Heh, found a couple... http://physics.kenyon.edu/EarlyApparatus/Electrical_Measurements/Resistance_Boxes_and_Rheostats/Garland34a.JPG and http://physics.kenyon.edu/EarlyApparatus/Electrical_Measurements/Resistance_Boxes_and_Rheostats/Greenslade72a.JPG
[08:14:29] <Jymmm> ah, here we go... http://physics.kenyon.edu/EarlyApparatus/Electrical_Measurements/Resistance_Boxes_and_Rheostats/Resistance_Boxes_and_Rheostats.html
[08:26:49] <ries> Jymmm: where had these at school.. and I am not that old!
[08:36:06] <Jymmm> ries: "You know you're an old fart when... There were exposed brass electrical contacts within reach of children" ;)
[08:36:20] <ries> Jymmm: I wish you didn't say that :D
[08:36:23] <jdh> heh
[08:36:25] <ries> now I just realise.....
[08:37:28] <jdh> cloth covered wires running from insulators across the floor joists?
[08:37:39] <Jymmm> knot and tube
[08:38:23] <skunkworks> knob ;)
[08:39:08] <Jymmm> I've been been a in a place where knob and tube wiring was is regular use, just in abandoned buildings and at the hardware store
[08:39:20] <Jymmm> ^never
[08:39:42] <jdh> I worked in a plant that still had shafts and pulleys running across the top to power machines
[08:40:10] <cradek> Jymmm: around me LOTS of houses still have and use it. I have some that's in use.
[08:40:30] <cradek> there's nothing wrong with it, it's a perfectly fine technology
[08:40:32] <jdh> it was pretty cool looking. huge leatherish belts, oilers on the pulleys
[08:41:05] <cradek> (I also bet you're wrong that you've never been somewhere where it's in use)
[08:41:11] <Jymmm> cradek: Yeah, there are a few places around here that still have some thus why I've probably seen it in the hardware store, including cloth wiring.
[08:41:23] <cradek> usually wiring is not visible
[08:41:24] <Jymmm> cradek: BRAND NEW too
[08:41:52] <Jymmm> Who in the sel makes much less sells cloth wiring is beyond me
[08:41:55] <cradek> well I'd be surprised to see it put in anywhere new... I doubt that's code anywhere.
[08:41:58] <Jymmm> hell^
[08:42:20] <Jymmm> No, but I suspect for repairs
[08:42:31] <Jymmm> maybe rat chewed or something
[08:45:36] <PetefromTn> I worked in a custom woodshop in downtown Knoxville that had all those old pulleys and shafts running to power the old machines but the machines were gone replaced by much newer state of the art machines. The floor was all tongue and groove wood and there were places it felt like a roller coaster when walking across the shop. Honestly it was really easy on your feet compared to the concrete slab I work on out in my shop.
[08:45:36] <PetefromTn> It is always warm and gives a little when you walk on it making it easier on you. We even had those old wood carts with the massive castors and plank decks to move materials around.
[08:46:25] <jdh> Pete: the one I was talking about was the old rohm and haas plant in knoxville.
[08:46:45] <jdh> next to 40 by 17th
[08:46:55] <PetefromTn> Aah interesting.. I worked in the building that burned down about four years ago..
[08:47:27] <PetefromTn> It was a damn shame actually it was kinda interesting building but I hear they are planning some nice new buildings for that place now.
[08:48:19] <PetefromTn> They said some homeless people built a fire in the next door building and it got out of hand and spread to the rest of the adjoining buildings.
[08:48:44] <jdh> is the plant still there?
[08:48:54] <PetefromTn> They had just recently bought a brand new fancy massive wide belt sander and a cyclone dust evac system for it and it all went up in smoke.
[08:49:36] <PetefromTn> No the owner moved his business to Oliver Springs where his property is and it was just way to far to drive for me so I had to get a job closer to home.
[08:51:25] <PetefromTn> Rohm and Haas is still there I think but might be in a new building, google says they are on Dale avenue now. Who knows.
[08:51:53] <jdh> it was on dale then
[08:52:18] <PetefromTn> I was just cutting some plexiglass for some cabinet door windows.
[08:52:29] <PetefromTn> Stuff cracks if you look at it the wrong way.
[08:52:41] <PetefromTn> okay then they are still there I guess.
[08:52:47] <jdh> they used to make plexiglas a that plant
[08:53:11] <PetefromTn> LOL maybe I should call them and complain.
[08:53:36] <PetefromTn> I just remember all the time it smelling like coffe from the coffe plant nearby downtown. Smelled like burned coffee all the time LOL
[08:53:46] <jdh> they shipped all plexi mfg to china in the early 80s due to EPA
[08:53:58] <PetefromTn> that explains it...
[08:54:13] <PetefromTn> Seems like if it gets the least bit hot from the cut it crazes and cracks..
[08:54:24] <PetefromTn> ANNOYING!!
[08:54:42] <jdh> I had code that made paint base for sherwin williams and insecticide. Turns out they are almost the same thing.
[08:55:15] <PetefromTn> Really no kidding... Nice to smell that in your house....
[08:55:23] <jdh> I've cut acrylic on my router. Never had any problems as long as I moved fast enough.
[08:55:36] <PetefromTn> CNC router?
[08:55:39] <jdh> yeah
[08:55:58] <PetefromTn> I cut acrylic all the time actually but these pieces are just 1/8 inch thick and it crazes bad.
[08:56:23] <jdh> use glass
[08:56:29] <PetefromTn> Mostly cut it on my tablesaw but this is radiused so I hit it with the bandsaw.
[08:56:41] <PetefromTn> I use the plastic for safety reasons..
[08:57:09] <PetefromTn> If it is lower close to the floor I use plastic, if it is up out of the reach of kids I use safety glass...
[08:57:36] <jdh> c'mon, pandering to safety fears just breeds weak children.
[08:57:40] <PetefromTn> Not sure if that is a great idea or not...
[08:58:13] <PetefromTn> LOL yeah exactly... Hell when I was a kid we just shoved our heads thru the non safety glass and got cut and went on our merry way hehehe
[08:58:58] <PetefromTn> plus the plexi I can cut myself here to the radiused top doors shape without paying a premium
[08:59:34] <PetefromTn> the stuff looks exactly like a piece of glass once it is installed. cheaper to replace and safer somewhat.
[09:00:43] <PetefromTn> Just finished installing these bookshelf cabinets in a master bedroom the other day now I am trying to finalize the little details and I am going back over tomorrow to install all the trim and base mold, crown, crown base etc...
[09:01:24] * skunkworks hates trim work...
[09:02:55] <PetefromTn> Yeah me too but it is what pays the bills right now. Plus I have been doing it for almost 20 years so I am pretty good at it. Here is a pic of the unit so far.. Still needs all the trim and doors and pocket doors installed etc...
[09:03:10] <PetefromTn> http://imagebin.org/287973
[09:04:18] <PetefromTn> It is over 9' tall and nearly 20' wide... Hard to tell from the pictures....crappy cell phone pics.
[09:09:47] <skunkworks> Nice!
[09:10:29] <skunkworks> we have a unfinised wall by the back door that we want to do some sort of built in...
[09:10:50] <skunkworks> not looking forward to it
[09:11:02] <PetefromTn> Thanks man. Nothing too fancy but it will be nice when it is done. I am installing another little piece of cherry in the main opening that will house the dvd/cable box and lift the TV up
[09:11:56] <PetefromTn> aah it is not that bad. That one in the picture the floor goes away from left to right over 3/4 inches... Pretty bad when you are shimming level with 3/4 plywood blocks but whatyagonnado..
[09:13:09] <PetefromTn> Well I better get my butt back out there and finish the doors and tv stand stuff so I can install it tomorrow. Talk later guys.
[10:17:52] <CaptHindsight> heading over to Keling (AutomationTechnologies) today, anyone need anything?
[10:18:09] <archivist> one each of everything
[10:18:19] <CaptHindsight> parts examined, detailed questions, etc etc?
[10:20:37] <jdh> see how fast you can cut 3mm acrylic with their cheapo 40w
[10:27:02] <CaptHindsight> http://www.mouser.com/new/Intel/intel-galileo-development-board/?gclid=CJv209HSj7wCFa9aMgodZEoA7w as much i dislike Intel I picked one up last night
[10:28:08] <`Nerobro> how much was it?
[10:28:22] <CaptHindsight> $60
[10:29:19] <CaptHindsight> no gpu, but arduino headers and mini-PCIe, USB and ethernet
[10:30:33] <CaptHindsight> when I get time I might try Linuxcnc on it
[10:32:07] <CaptHindsight> in store only at Microcenter for $60, Mouser has 6k on backorder
[10:32:14] <pcw_home> this looks pretty decent for ~ $60
[10:32:16] <pcw_home> http://www.msi.com/product/mb/J1800I-.html
[10:33:33] <pcw_home> supposed to be 2-3 times as fast as the Atoms and lower power
[10:33:37] <CaptHindsight> http://www.asrock.com/mb/overview.asp?Model=E350M1 ~$65 with coreboot support
[10:35:09] <pcw_home> Yeah but the Baytrails celerons have really impressve performance /watt
[10:35:13] <CaptHindsight> I'm not really sure what x86 with duino pinouts realy gets you since most of the duino IO boards are so clumsy and overpriced
[10:35:44] <CaptHindsight> yeah, depends on if you want cpu or gpu performance per watt
[10:37:54] <CaptHindsight> AMD APU in a dunio foorprint with HDMI night be another odd board
[10:47:58] <skunkworks> needs 2 nics for ethernet interface cards ;)
[11:02:13] <CaptHindsight> just for fun I'd like to plug an AMD R290x into the Galileo and post some benchmarks
[11:55:02] <Tom_itx> pcw_home, are you gonna test one?
[11:56:10] <pcw_home> The MSI MB?
[11:56:29] <Tom_itx> yeah
[11:57:09] <pcw_home> As soon as they are available (maybe end of month or Feb)
[11:58:17] <pcw_home> there should be a bunch of baytrail MBs coming out
[12:02:01] <CaptHindsight> http://ark.intel.com/products/78866/Intel-Celeron-Processor-J1800-1M-Cache-up-to-2_58-GHz
[12:02:36] <CaptHindsight> Max TDP 10 W
[12:03:19] <CaptHindsight> any idea what the mini-itx board prices will be? Recommended Customer Price TRAY: $72.00
[12:03:32] <pcw_home> msi is ~$60
[12:03:41] <Tom_itx> pcie?
[12:03:46] <pcw_home> yes
[12:03:54] <CaptHindsight> so less than the tray price :)
[12:05:05] <CaptHindsight> 1 PCI Express 2.0 x1 slot
[12:05:05] <pcw_home> if you look at the MSI MB theres almost nothing on it
[12:06:24] <CaptHindsight> "MSI Reminds You...• The graphic output can only work with CPUs with GPUs core inside." ??
[12:06:46] <pcw_home> whatever that means...
[12:06:52] <archivist> latency
[12:07:55] <pcw_home> I dont think so (when video was a memory bandwidth hog this was true)
[12:07:58] <CaptHindsight> only a 1 PCI Express 2.0 x1 slot, so you'd have to adapt most graphics cards to fit in the x1 slot
[12:08:24] <skunkworks> maybe.. The laptop I have been playing with has the intel 4000 video. It actually has decent latency for a laptop
[12:08:30] <CaptHindsight> onboard graphics only
[12:08:35] <pcw_home> why woul you want to use a graphics card?
[12:08:53] <CaptHindsight> play Quake while milling, what else?
[12:08:57] <archivist> axis
[12:09:19] <pcw_home> axis will run just peachy on Intel graphics
[12:09:26] <CaptHindsight> yes, it's not BBB
[12:09:37] <CaptHindsight> yes but it won't have coreboot support
[12:09:57] <skunkworks> core boot snob!
[12:10:03] <pcw_home> well thats intesl fault, at least they dumped the Power rangers video
[12:10:28] <CaptHindsight> Intel is hiring a coreboot dev, or searching for one anyway
[12:10:57] <IchGuckLive> hi all B)
[12:11:11] <pcw_home> if they want to say alive in deeply embedded they probably need to
[12:13:39] <CaptHindsight> they have contacted me several times, they want to offer a little bit of coreboot support for a very limited range of parts
[12:13:49] <mozmck> do any motherboards come with coreboot? can you replace the existing BIOS/UEFI with coreboot?
[12:14:22] <CaptHindsight> they are trying to compete with ARM where users are given u-boot and working firmware for free
[12:15:08] <CaptHindsight> mozmck: http://www.asrock.com/mb/overview.asp?Model=E350M1 has coreboot support, but you have to flash it yourself
[12:15:46] <CaptHindsight> mozmck: yes, coreboot replaces the factory BIOS/UEFI malware
[12:16:11] <mozmck> :) I have an MSI board now - I'll have to look it up.
[12:16:33] <IchGuckLive> coreboot is the futher of all cnc
[12:17:22] <CaptHindsight> Google has actually been porting coreboot to the intel devices they use for all their devices including chromebooks
[12:17:39] <mozmck> I've read a little on the UEFI stuff where it's hard to install a non-microsoft OS.
[12:17:50] <CaptHindsight> 3 of the core coreboot devs work for Google now
[12:18:08] <mozmck> hope that doesn't corrupt them too bad
[12:18:14] <CaptHindsight> mozmck: you just need to flip a setting in UEFI and reboot
[12:19:38] <CaptHindsight> we just installed dual win7 and Linux on a few laptops, so just take more reboots than others to get the install started
[12:19:46] <mozmck> I see. Why are the linux distros going to all the pains to support it then? Stuff I've read looks like a mess.
[12:19:49] <CaptHindsight> so/some
[12:20:23] <CaptHindsight> not sure, maybe they are concerned that the switch to turn off the secure boot will be removed
[12:20:57] <mozmck> could be.
[12:21:12] <CaptHindsight> secure boot for windoze, an oxymoron
[12:21:39] <CaptHindsight> like a bank vault door for your Saran wrap house
[12:24:24] <mozmck> :) more like "lock-in boot"
[12:24:33] <CaptHindsight> yeah, all it is
[12:24:57] <mozmck> Google is probably just trying to get spyware and google lock-in into coreboot...
[12:25:02] <CaptHindsight> people also think that linux installed on their systems gets them security..
[12:25:41] <CaptHindsight> unfortunately with EFI you have 2-3 other closed kernels running in background as well
[12:25:51] <mozmck> Like installing it beside win7 and then using win7?
[12:27:36] <CaptHindsight> they data collectors are awfully paranoid, backdoors in BIOS. OS, encryption and they collect every bit through the networks
[12:29:15] <CaptHindsight> secure boot is just lockin, there's no security with it except M$ profit security
[12:30:10] <CaptHindsight> but they didn't notice Android until too late
[12:31:14] <CaptHindsight> I'm just glad that several ARM vendors jumped into the phone and tablet market or we'd be stuck with nvidia secure boot
[12:38:21] <pcw_home> Microsoft lost its grip as soon as there were alternatives they could not control by witholding windows
[12:40:45] <CaptHindsight> apple and android
[12:42:25] <mozmck> I got my first android device the other day and was not impressed with the google lock-in. it wanted me to log in to my google account to do anything - and I don't have a google account.
[12:42:45] <einar_> I set the HOME_xxxx parameters in the .INI file. But Axis does not move when I press Home. It just works as if there is no home switches. What else do I have to do to make it work?
[12:42:46] <mozmck> I did find f-droid and installed some apps.
[12:43:38] <pcw_home> at least you have a choice of lock-ins :-)
[12:43:56] <IchGuckLive> einar_: helow you need alt least 3 parameters
[12:44:04] <mozmck> heh, yes, but I don't like either of them
[12:44:13] <IchGuckLive> einar_: did you get a input for homing
[12:44:16] <skunkworks> einar_, did you read through http://www.linuxcnc.org/docs/2.5/html/config/ini_homing.html
[12:46:10] <IchGuckLive> einar_: querry
[12:47:56] <CaptHindsight> yes, now Google is closing its grip
[12:48:54] <CaptHindsight> maybe just open a shared google store account, i wonder how many devices may be tied to 1 account?
[12:49:08] <einar_> I got limit switches on +Limits. My config here: http://sjaavik.no/linuxcnc-dev/univstep/
[12:49:30] <IchGuckLive> einar_: did you see my querry
[12:49:56] <IchGuckLive> einar_: is thel imit + switch also the homeswitch
[12:50:12] <CaptHindsight> "no really I have 13,657 Droids, 8,543 Galaxy 3's and 439 G10'a
[12:50:16] <IchGuckLive> or are there seperate ones
[12:58:45] <mozmck> CaptHindsight: that might help, but I couldn't even put anything on the calendar app that came with it without logging in to google. They want all of your data on their servers.
[13:02:30] <GuShH_> mozmck: bend over and take google's juicy rod.
[13:03:47] <cradek> mozmck: I recently hung a paper calendar on the wall at home again. it works great, and has pictures.
[13:04:28] <IchGuckLive> cradek: O.O girls are always the best in the shop
[13:04:34] <jdh> I have a few of those on my cube walls. I just keep them on the months with pics I like
[13:04:46] <cradek> IchGuckLive: you assume a lot
[13:04:48] <jdh> June 2002 is pretty nice.
[13:04:49] <mozmck> :) That's what I have always used and still do. I was just playing with things on this cheap tablet.
[13:05:10] <cradek> mozmck: I didn't have one for a while, but now I notice how useful it is again
[13:05:42] <jdh> (no chick calendars, just cave diving)
[13:05:44] <mozmck> Mainly got it to play with using as a touch screen interface.
[13:07:06] <mozmck> cradek: oddly, I've never gone for all the tech stuff. I use some of it, but I've never had a "smart" phone, and I use a small notebook and pen for contacts etc :)
[13:07:17] <CaptHindsight> mozmck: yeah, that's the down side of Google and why the devs just ignored my interest in adding a large HD to the Chromebooks, they are told to encourage the use of their cloud
[13:07:51] <mozmck> most people I see are slaves of their little screens - and I think it is rotting their brains too :)
[13:08:07] <cradek> mozmck: I have a "smart" phone from work, and I'm used to it now, but I would be tempted to go without if I had to pay for it.
[13:08:35] <CaptHindsight> just for fun I installed 50 apps to a brand new nexus phone, within 2 weeks it was useless
[13:08:36] <mozmck> Yes, I don't like the cloud stuff for most things either. Especially for all my personal docs etc.
[13:09:15] <CaptHindsight> now I only have 4 that didn't come with the install and they require no access to my phonebook or location
[13:09:38] <mozmck> hah! trying to emulate windows!
[13:10:17] <CaptHindsight> why the hell does a calculator need to access my location and phone numbers?
[13:10:30] <mozmck> yeah - one wonders.
[13:12:22] <CaptHindsight> the phone used to go nuts at 3am and lose 50% of the battery while connected to various ip locations
[13:12:52] <CaptHindsight> like they were just rsycned with it
[13:12:57] <CaptHindsight> or similar
[13:13:44] <jdh> teh google needs to know where you calculate
[13:14:10] <CaptHindsight> location based algebra
[13:14:31] <jdh> needs to know if you want a , or a .
[13:16:49] <CaptHindsight> I'd be happy to pay for apps if they just did what I wanted and not traded my history for use
[13:17:32] <CaptHindsight> but they don't offer that and most people don't seem to care
[13:33:57] <IchGuckLive> BYE
[15:42:14] <mozmck> anyone know if an acroloc is a good machine?
[15:42:51] <mozmck> looks like it has a 12 tool changer
[15:43:07] <CaptHindsight> skunkworks has one
[15:43:32] <CaptHindsight> they were easy to run from what I read
[15:43:44] <CaptHindsight> they use their own unique tool holders
[15:44:01] <mozmck> hmm, could be a problem. this one doesn't have any.
[15:44:23] <CaptHindsight> how much do they want for it?
[15:44:45] <CaptHindsight> there was one near here that was for sale for months <$2k
[15:44:48] <mozmck> $2500
[15:44:59] <CaptHindsight> good size a decent shape
[15:45:19] <CaptHindsight> where about are you?
[15:45:40] <mozmck> he says it made one aircraft part all it's life. table is 14" x 54"
[15:45:43] <mozmck> north texas
[15:46:56] <mozmck> old wells index cnc mill for $800 that needs new electronics
[15:47:41] <uw> pics?
[15:49:04] <mozmck> http://dallas.craigslist.org/ndf/for/4256424656.html
[15:49:07] <CaptHindsight> mozmck: ask skunkworks about them when he's back, he has it partially apart
[15:49:15] <mozmck> ok
[15:49:55] <mozmck> here's a wells index for 2k that looks clean: http://dallas.craigslist.org/ftw/tls/4267387793.html
[15:52:48] <cradek> manual drawbar?
[15:53:02] <jmasseo> that would be nice in my house
[15:53:04] <jmasseo> nice and close.
[15:53:35] <mozmck> hey! you're scared of a haas! :)
[15:53:46] <cradek> but surely $2000 is way too much for a stripped machine
[15:53:49] <CaptHindsight> http://tinyurl.com/km2ew99 what you find on ebay for under $8K
[15:54:03] <jmasseo> i wouldn't say i'm scared of the haas.
[15:54:18] <mozmck> just kidding ;)
[15:54:35] <jmasseo> god knows how long it'll take to get signed off on it
[15:55:05] <jmasseo> i'm considering playing with the emco on saturday and making sure i understand wtf i'm doing.
[15:55:22] <mozmck> I've got too many machines. I need to scrap or sell a couple lathes and a Doall mill and get a cnc mill set up.
[15:56:01] <jmasseo> what kind of lathes are you trying to offload?
[15:56:33] <mozmck> old, and needing work. I have a logan 14" that needs work.
[15:56:56] <mozmck> another may be spoken for, and I guess that's all for now.
[15:57:04] <MrSunshine> ahh machine painted, and new spindle on it and reassembled .. ripping material with new spindle =)
[15:57:08] <jmasseo> i would like to get a smaller lathe for the house.
[15:57:13] <jmasseo> i'm guessing that mill is a full sized knee mill?
[15:57:19] <MrSunshine> http://www.youtube.com/watch?v=k16CVVTwMk0&feature :P
[15:57:24] <mozmck> about 6500 lb
[15:57:31] <mozmck> yes
[15:57:50] <jmasseo> wouldn't be a bad idea for the space to have something like that.
[15:58:30] <mozmck> Well, it needs work too. I would sell it for about scrap price to get rid of it.
[15:58:42] <jmasseo> scrap price is like 10 cents a pound.
[15:58:53] <jmasseo> how much work does it need?
[15:59:10] <mozmck> It ran when I got it but had a tick in the head. It has hydraulic power feed that was working.
[15:59:26] <mozmck> I think it might need bearings?
[15:59:58] <uw> "This cnc machine made one part for an aircraft its entire life"
[16:00:13] <uw> sad but so believable
[16:00:39] <CaptHindsight> one part, 3 million times :)
[16:00:51] <uw> lol yup
[16:01:14] <jmasseo> what is wrong with the logan?
[16:03:55] <mozmck> I forget what all now. It had a variable speed spindle using the variable pulleys, and someone welded them together making it single speed.
[16:04:05] <jmasseo> awesome.
[16:04:11] <Deejay> lol
[16:04:32] <jmasseo> does it have power feed?
[16:04:37] <mozmck> That's the main thing that I know of. I think a new set could be made fairly easily, but it all takes time.
[16:04:46] <Loetmichel> MrSunshine: on my machine i would quadruple the feedrate ;-)
[16:04:53] <jmasseo> i have more time than cash these days.
[16:05:16] <mozmck> It has a threading gear box (which might need work), and I think standard power feed (mechanical)
[16:05:28] <jmasseo> right
[16:05:58] <mozmck> It had a motor reversing mechanism that is worn, and I bought a reversing contactor but never got back to that project.
[16:06:31] <jmasseo> mechanism?
[16:06:34] <jmasseo> is it 3phase?
[16:07:23] <MrSunshine> Loetmichel, that was a test only at 1000mm/min first run with the spindle so :P
[16:07:32] <MrSunshine> and doesnt sound like it hates it :P
[16:14:02] <Loetmichel> my little 800W spindle doing its first dust in MDF ... 16mm 2 flute mill bit, 4200mm/min... -> http://www.youtube.com/watch?v=dEQZ_TY5q8o
[16:15:09] <Loetmichel> facing off the pable
[16:21:24] <uw> mikrokopter when complete
[16:23:17] <Deejay> hi uw
[16:23:31] <uw> halo Deejay
[16:23:39] <uw> any new CNC work?
[16:24:21] <Deejay> nothing noteworthy
[16:26:37] <Deejay> bedtime for me now
[16:26:39] <Deejay> gn8
[16:38:01] <MrSunshine> are you sure that is 4200mm/min ? looks a bit slow? =)
[16:58:45] <NickParker> Hmm... I don't suppose mendel-parts.com has any sort of support infrastructure still running does it?
[16:59:06] <NickParker> My gen6 is really acting up lately, and it's getting in the way of finishing a hand.
[17:02:33] <NickParker> ops, wrong channel
[17:02:37] <NickParker> my bad
[17:09:25] <uw> yea...wrong channel indeed
[17:16:20] <CaptHindsight> http://www.automationdirect.com/adc/Technical/Catalog/Programmable_Controllers/DirectLogic_Series_PLCs_%28Micro_to_Small,_Brick_-a-_Modular%29
[17:16:45] <CaptHindsight> anyone use the DirectLogic series PLC's ^^ ?
[17:17:10] <CaptHindsight> trying to figure out the programming software limit of the free vs paid version
[17:19:21] <CaptHindsight> http://www.automationdirect.com/adc/Shopping/Catalog/Software_Products/Programmable_Controller_Software/DirectLOGIC_PLC_Programming_Software_%28DirectSOFT%29
[17:19:33] <CaptHindsight> 100 words max for the free version
[17:33:41] <zeeshan> for my personal use
[17:33:46] <zeeshan> i use allen bradley micrologix plcs
[17:33:58] <zeeshan> i downloaded a cracked copy off the internet for rslogix (programming software)
[17:34:00] <zeeshan> lol
[17:34:23] <zeeshan> it's the most useless software i've used in my life
[17:34:56] <Loetmichel> i learned plc programming some time ago on AEG modicon...
[17:35:36] <Loetmichel> that was surprisingly well desinged for a 80286-era dos program ;-)
[17:35:53] <zeeshan> its all ladder logic
[17:36:02] <zeeshan> it sux
[17:36:02] <zeeshan> ;p
[17:36:50] <Loetmichel> the even made a mode where you could program the plc in KOP ("Kontaktplan", electrical power schematics with contactors and stuff) and in logic symbols schematics
[17:37:04] <zeeshan> pretty
[17:37:22] <Loetmichel> for the less "programmer" electrical engineers at that time
[17:39:22] <Loetmichel> not only pretty and more or less a "talking printout" possible, but also very convenient for the engineers who had desinged classical contatcor boxes beforehand
[17:57:24] <JT-Shop> crap it was cold on the bridge today
[18:11:15] <Tom_itx> work faster
[18:16:20] <JT-Shop> you can only work so hard watching someone work
[18:17:01] <Tom_itx> oh, were you the one leaning on the shovel?
[18:17:35] <JT-Shop> I was up on the bridge and supporting my partner who was working off of a ladder in the creek
[18:17:47] <JT-Shop> you know keep him supplied and working
[18:17:52] <Tom_itx> i always see city crews working on the corner ... maybe 5 or 6 of em and only one or two are doing anything
[18:18:39] <JT-Shop> yea, the big joke in New Orleans is what is yellow and black and sleeps 6?
[18:18:56] <JT-Shop> the sewage and water board trucks
[18:18:59] <Tom_itx> i believe that coming from down there
[18:19:22] <Tom_itx> that or slowvanna
[18:19:42] <Tom_itx> (savannah)
[18:21:32] <JT-Shop> we get er done and don't mess around
[18:24:04] <Loetmichel> Tom_itx: http://s395.photobucket.com/user/tkoerting/media/manager_arbeiter.jpg.html
[18:24:08] <Loetmichel> this way?
[18:25:07] <Tom_itx> :)
[18:25:40] <Tom_itx> someone has to act like construction cones
[18:26:11] <syyl-> try not to move all day long?
[18:26:31] <Loetmichel> syyl-: that would be government clercs
[18:26:42] <Loetmichel> :-)
[18:59:37] <tjb1> I need 20 of these - https://www.dropbox.com/s/rcxzbwfcnohvegz/crownedcover.pdf
[19:39:56] <owhite> hello everyone. I'm doing some hal programming on my mesa 5i20 card. One of the inputs to the card is meant throw an e-stop in linuxcnc. Could anyone make a suggestion for what pin I would tie the hm2_5i20.0.gpio.000.in to?
[19:41:49] <Tom_itx> in or out?
[19:42:55] <owhite> so suppose theres a switch on one of the physical pins of the 5i20, the other side of the switch is tied to ground.
[19:43:19] <owhite> The 5i20 detects if that switch is open or close. When it's open, I want it to throw an estop.
[19:43:45] <Tom_itx> net estop-loop iocontrol.0.emc-enable-in <= hm2_[HOSTMOT2](BOARD).0.gpio.032.in
[19:45:00] <owhite> thanks. iocontrol.0.emc-enable-in is already in a net, do you know what created that net? or what command I would use to modify that net?
[19:45:23] <owhite> its not defined in any of my .hal files.
[19:46:16] <Tom_itx> it's a part of the iocontrol
[19:46:23] <Tom_itx> signal
[19:47:40] <owhite> would I use unlinkp?
[19:48:31] <owhite> I'm asking because if I run that command you're suggesting it will complain that it's already part of a net.
[19:49:17] <Tom_itx> you should find where iocontrol.0.emc-enable-in is used then
[19:49:49] <owhite> ok.
[19:50:06] <Tom_itx> that's the signal you want the pin tied to
[19:50:35] <Tom_itx> i think
[19:52:33] <owhite> :-) what's the worst that could happen?
[20:08:15] <owhite> hey - do all the comments that happen on #linuxcnc get logged somewhere?
[20:08:37] <Tom_itx> yep
[20:08:54] <owhite> okay, in that case I think I'll post most solution here.
[20:10:24] <owhite> my pin on the 5i20 was hm2_5i20.0.gpio.014, so I put: setp hm2_5i20.0.gpio.014.is_output false net and3_a and2.3.in0 hm2_5i20.0.gpio.014.in_not net and3_b and2.3.in1 iocontrol.0.user-enable-out net estop-loop and2.3.out => iocontrol.0.emc-enable-in and it worked. Thanks for everyone's patience with the spam
[20:10:49] <owhite> bleh. No end of lines. I'll let history figure that one out.
[22:49:35] <CaptHindsight> from an ebay listing for linear bearings "some of the ball bearings have come out so you will need to put them back in"
[22:49:44] <eric_unterhausen> no prob
[22:50:04] <eric_unterhausen> for u
[22:51:06] <CaptHindsight> linear rail, linear slide, linear slide rail, linear bearing slide, linear bearing slide rail..... I give up
[22:51:52] <eric_unterhausen> what's annoying is the company named linear that makes food equipment
[22:52:25] <CaptHindsight> lol
[22:55:45] <CaptHindsight> linear motor positioners don't have leadscrews or ballscrews, but that's the fun of ebay
[22:56:20] <eric_unterhausen> there are all those linear stepper motors with lead screws
[22:57:00] <eric_unterhausen> kinda surprsed how many of those show up on ebay
[22:57:20] <CaptHindsight> I just wasted half an hour looking for low profile linear rail and bearing blocks
[22:57:40] <eric_unterhausen> the problem is that so many of them aren't really made to take a load
[22:57:56] <CaptHindsight> it's almost as useless as searching on amazon now
[22:57:59] <eric_unterhausen> machining loads
[22:58:54] <CaptHindsight> these are for a contactless application, no real load except on the direction of motion
[22:59:09] <eric_unterhausen> ur in luck
[22:59:39] <Tom_itx> pbclinear
[23:00:23] <CaptHindsight> used linear servo motors 800mm long for $100
[23:00:36] <eric_unterhausen> what is it?
[23:00:53] <eric_unterhausen> I have some used magnet tracks
[23:01:34] <CaptHindsight> yes, that type of servo
[23:01:38] <eric_unterhausen> pretty much totally useless
[23:03:04] <CaptHindsight> I use them all the time
[23:03:27] <eric_unterhausen> the ones that work are not useless
[23:03:33] <eric_unterhausen> the ones I have are
[23:03:47] <CaptHindsight> recall the brand and size?
[23:03:58] <eric_unterhausen> magnets are falling apart
[23:04:11] <CaptHindsight> not good, pretty much useless
[23:04:15] <eric_unterhausen> what would you use for a forcer
[23:04:16] <eric_unterhausen> ?
[23:05:08] <CaptHindsight> http://www.ebay.com/itm/C105954-Kollmorgen-Motion-Platinum-DDL-Linear-Motor-w-768mm-Magnetic-Guide-Rail-/331091287648?pt=LH_DefaultDomain_0&hash=item4d16941e60
[23:06:01] <eric_unterhausen> I had heard you could bolt them together, never seen it though
[23:06:07] <CaptHindsight> yes
[23:06:41] <eric_unterhausen> after my recent magnet track disaster, I'd want to see a better view of the innards
[23:07:01] <eric_unterhausen> but that's worth 100
[23:07:13] <CaptHindsight> that one is probably ~200 N
[23:07:49] <eric_unterhausen> make sure they ship it with the forcer packaged separately
[23:08:00] <CaptHindsight> the magents look pretty good the forcer looks beat
[23:08:17] <CaptHindsight> and not in a bag :)
[23:09:13] <CaptHindsight> that looks like it was under salt water
[23:09:15] <eric_unterhausen> I think the magnets may be delaminating
[23:09:36] <eric_unterhausen> you scratch them, years later the plating rusts off
[23:09:55] <eric_unterhausen> what a pain to try to clean
[23:10:07] <CaptHindsight> the insulation around the coils have the impression of the magnets
[23:10:28] <CaptHindsight> they should not be in contact
[23:10:39] <CaptHindsight> so that is really odd
[23:11:29] <CaptHindsight> http://imagebin.org/287237 this stage uses a few linear servos
