[00:37:25] <ThadiusB> ok, so I think i need to blacklist paraport_pc in order to get my parallel card to read, any suggestions, advice, confirmation?
[01:17:09] <awallin> http://www.youtube.com/watch?v=qw6m9VbJW7s
[01:19:29] <ThadiusB> anyone know why linuxcnc might not communicate with my machine? using ubuntu 10.04, pci-e parallel card. Seems i'm not getting signal to my board
[01:21:49] <awallin> ThadiusB: check that you are using a parport config, and that the pp-address is right. the check what actually comes out of the port with a voltmeter or oscilloscope
[01:25:48] <ThadiusB> havent read anything on "paraport config"
[01:26:10] <ThadiusB> would you mind explaining a lil more, sorry quite new to ubuntu and linuxcnc
[01:33:36] <alex4nder> gents
[01:35:56] <awallin> ThadiusB: check your BIOS or maybe the parport-card at bootup. it should have a hex address like 0x278 or something similar. That must go in the HAL-file on the line that loads the parport driver.
[01:37:18] <ThadiusB> is there a terminal command to show my address?
[01:40:55] <archivist> yes and I cannot remember its name
[01:42:43] <archivist> lspci
[01:45:08] <ThadiusB> ok, in the linuxcnc.conf file i need this "install parport_pc /bin/true" correct?
[01:49:43] <pfred1> lspci -vvv
[01:54:43] <ThadiusB> talk about confusing, i'm so lost
[01:58:50] <archivist> pastebin the output
[01:59:25] <ThadiusB> 4:00.0 Parallel controller: Oxford Semiconductor Ltd Device c110 (prog-if 02)

[01:59:28] <ThadiusB> Kernel modules: parport_pc
[01:59:44] <ThadiusB> thats my pci-e parallel card
[02:00:04] <Jymmm> ThadiusB:
http://codepad.org/ if more than two lines please
[02:02:00] <ThadiusB> ok
[02:04:05] <ThadiusB> what else should i post in order to help out?
[02:06:20] <archivist> you will get better output doing sudo lspci -vvv
[02:13:13] <ThadiusB> http://codepad.org/G5o03PgJ
[02:19:29] <ThadiusB> reboot
[02:23:19] <pfred1> ThadiusB your port is either df00 or de00
[02:24:03] <pfred1> you might have to enter it as 0xdf00 or 0xde00 though I forget
[02:30:26] <ThadiusB> in my conf file right?
[02:32:02] <pfred1> you can't use stepconf?
[02:32:47] <ThadiusB> i made my initial, thought i could just edit it
[02:32:52] <ThadiusB> could start over though
[02:33:55] <pfred1> no you load your file
[02:34:13] <pfred1> in the beginning just pick your config and modify it
[02:34:23] <pfred1> then save it again
[02:34:25] <ThadiusB> ok, so instead of standard 0x378 plug in one of those addresses listed?
[02:34:30] <pfred1> right
[02:34:40] <pfred1> you probably have a 2 port card
[02:34:49] <pfred1> try one if it doesn't work go back try the other
[02:35:08] <pfred1> you can try it right in stepcong use the axis test
[02:35:14] <pfred1> stepconf even
[02:35:44] <ThadiusB> we have lift off!!!!
[02:35:50] <pfred1> easy peasy
[02:36:21] <ThadiusB> dude, thank you so much
[02:36:27] <ThadiusB> i've been at this for 3 hours
[02:36:30] <pfred1> now you can fool with the axis test
[02:36:42] <pfred1> figure out your accel and max rate and all that good stuff
[02:37:44] <pfred1> if the max speed maxes out on you just close the pop up then it gives you a little more headroom the next time you pick test axis
[02:37:56] <pfred1> it is kind of strange
[02:38:41] <pfred1> I spent a lot of time in stepconf tweaking my drives
[02:38:47] <ThadiusB> awesome
[02:39:08] <pfred1> it is great when things start happening
[02:39:18] <Jymmm> http://www.sweex.com/en/assortiment/connectivity/pci-cards/PU005V2/
[02:42:08] <ThadiusB> man i'm stoked
[02:42:16] <pfred1> heh glad to hear it
[02:42:16] <ThadiusB> now i just need to learn A LOT more
[02:42:26] <Jymmm> ThadiusB: which address was it?
[02:42:42] <pfred1> they got it so fast must have been the first one they picked
[02:42:59] <pfred1> ThadiusB I'd have helped you sooner but I was playing Quake in my other screen
[02:43:07] <Jymmm> lol
[02:43:14] <ThadiusB> dude, i understand
[02:43:15] <pfred1> well it traps my mouse
[02:43:24] <ThadiusB> <---quake, unreal, counterstike
[02:43:25] <pfred1> I can't get it back to this screen
[02:43:27] <ThadiusB> oldies but goodies
[02:43:37] * Jymmm introduces pfred1 to the PAUSE feature.
[02:43:41] <pfred1> on Linux you can run mod engines I use Darkplaces
[02:43:51] <pfred1> nah yo ustay trapped til you shut the game down
[02:44:03] <pfred1> though LordHavoc says i can run windowed
[02:44:30] <pfred1> 03:04 <@LordHavoc> honest and on his ISP
[02:44:38] <ThadiusB> ok, so limit switches aside, how do i go about setting limits in linuxcnc?
[02:44:42] <pfred1> he wrote Darkplaces
[02:44:53] <pfred1> in stepconf
[02:45:06] <pfred1> each axis page you have travel limits
[02:45:36] <pfred1> they are you machine's soft limits
[02:46:26] <ThadiusB> ahh, ok
[02:47:17] <pfred1> your Z you may have to go for a negative number to be in rage of some of the examples
[02:47:24] <pfred1> in the range even
[02:47:31] <pfred1> I think I had to use -2
[02:48:29] <pfred1> that drove me batty for a bit
[02:48:44] <ThadiusB> ahh, and what is "touch off"
[02:48:54] <ThadiusB> that for setting up against material on z?
[02:49:04] <pfred1> you have ot do that to get axis going
[02:49:26] <pfred1> you have to home each axis then touch off Z
[02:49:34] <Jymmm> pfred1: But "what is it?"
[02:49:38] <pfred1> then it'll run a program
[02:49:54] <ThadiusB> so its basically running down to your material for positioning?
[02:50:10] <pfred1> beats me but if yo udon't do it axis doesn't run
[02:50:25] * Jymmm lol @ pfred1
[02:51:11] <ThadiusB> ok, lol
[02:51:50] <pfred1> some people have those touch probes so maybe they can compensate for the thickness of them?
[02:52:21] <pfred1> there seems to be two scales relative and absolute or something
[02:52:44] <pfred1> as in you can offset everything
[02:53:34] <pfred1> which makes sense because what if you want to make multiple parts
[02:54:48] <Jymmm> As I see "Touch Off", it's basically the difference between absolute and relative position.
[02:56:53] <Jymmm> The corner of the material might be clamped at absolute 4,4 you want the relative position to be 0,0
[02:57:11] <alex4nder> yes
[02:57:23] <Jymmm> so the gcode/machine has a "valid" starting point.
[02:57:44] <ThadiusB> ahh
[02:58:16] <ThadiusB> so what i'm thinking of isnt touch off, its homing on the z axis?
[02:58:21] <pfred1> yeah it gives the machine a place to start scribbling
[02:58:31] <ThadiusB> when you touch down to the top of your material
[02:58:32] <ThadiusB> ?
[02:59:37] <pfred1> cut some air see how it goes
[03:00:10] <pfred1> then move up to a felt tipped pen they're popular to start off with
[03:00:22] <pfred1> cheaper than bits if you break them
[03:02:23] <Jymmm> ThadiusB: Also, think of a block that might be 4" or 6" tall as example and you want the "top of material" to be Z == 0
[03:03:36] <pfred1> well the top relative to the end of your bit right?
[03:04:08] <Jymmm> and typically a negative z move being "into" the material.
[03:04:20] <Jymmm> pfred1: yes
[03:05:25] <pfred1> in nay event it is a good idea to do some dry runs before you create your masterpiece
[03:05:35] <pfred1> just so you get familiar with the wteps
[03:06:11] <pfred1> well I'm out late here hitting the sack
[03:09:52] <ThadiusB> thanks for the help
[03:10:00] <ThadiusB> i'm just running through air :)
[05:22:12] <MattyMatt> pfred1 only one tyhing lacking in that stepper tute. pentawired 5 phase. I really don't get that. fortunately I don't need to to make the driver, I just need to make 5 half-bridges
[05:22:30] <MattyMatt> and worry about sequencing later
[05:24:15] <MattyMatt> I'd like to get by with fewer than 10 comparitors but I can't think how to do the current sensing except with a comparitor in both legs
[05:24:44] <archivist> just buy a 5 phase driver
[05:24:52] <MattyMatt> buy? what's that?
[05:24:55] <MattyMatt> :)
[05:25:15] <archivist> you have to get parts whichever way!
[05:25:17] <MattyMatt> I've got some nice microstepping but puny 0.7A ones
[05:25:46] <MattyMatt> I've got a bag of mosfets and I can dig up some LM339 somewhere
[05:26:42] <MattyMatt> 5 phase drivers cost a bomb. even non-current controlled half stepping ones are £50 used on ebay
[05:26:57] <MattyMatt> I can build as good as that easy
[05:27:29] <MattyMatt> 3x L298s and an arduino
[05:28:47] <MattyMatt> if there's a single chip driver available which can do 2A I'd like to know
[05:33:41] <MattyMatt> all the reprap people are buying new 2-phase motors, and the 5 phase motors don't cost much more, or didn't until recently 2-phase nema17 have got really cheap this year
[05:34:04] <MattyMatt> £6 each
[05:38:53] <MattyMatt> if 5 phase can do 3krpm under load, we can ditch the belts
[05:39:34] <Loetmichel> mornin'
[05:39:47] <MattyMatt> guten tag
[05:42:56] <Loetmichel> 3krpm out of a nema17 stepper?
[05:43:04] <Loetmichel> 2 or 5 phse: no way
[05:43:19] <Loetmichel> 2 phase: maximum 1000 RPM, 5phase maybe double
[05:43:38] <MattyMatt> I've seen nema23 doing 3k on youtube, with no load
[05:43:52] <Loetmichel> or you have to go WAAAAY beond the specs voltage-wise
[05:46:42] <MattyMatt> meh, that means I'll need those 10 comparitors
[05:47:38] <Loetmichel> MarkusBec: do you know how mutch voltage in the drives?
[05:47:51] <Loetmichel> and what voltage thhe motor is speced?
[05:47:56] <Loetmichel> grr
[05:48:00] <Loetmichel> MattyMatt was meant
[05:49:05] <Loetmichel> because ANY stepper can turn really fast if supplied with enough voltage... (until arcing /isolatioon failure occures)
[05:49:43] <Loetmichel> its the stepper principle
[05:50:02] <Loetmichel> Large inductances in the windings swiitcvhed REALLY fast
[05:50:08] <Loetmichel> switched
[05:50:11] <MattyMatt> the ones I want to make drivers for are 2.2A 0.28Ω penta wired
[05:50:48] <Loetmichel> any inductance resists current change.
[05:51:19] <Loetmichel> so to magnetize (let a current flow) fast into a inductor you need to get the voltage up
[05:51:36] <MattyMatt> I just noticed my nema17 ones (which I have drivers for) are 0.36deg :p that's halves the top speed
[05:51:46] <Loetmichel> and when you want to turn faster you have to switch faster
[05:52:00] <MattyMatt> yep
[05:52:30] <MattyMatt> 0.28Ω is low tho, for any stepper. these big ones should go fast
[05:54:10] <MattyMatt> if I give them 38V
[05:56:46] <Loetmichel> i've build a driver for a stepper (just out of curiosity) a very crude way: 325V DC supply, unipolar "4 phase" stepper nema17, 4 resistors for 500mA 320V ( 4 times 47 ohms 50W in series for each ) and 4 BU508 HOT to the gnd...
[05:57:19] <Loetmichel> works grat and the stepper can suddenly turn 4krpm... but not long, as it has heated um you could HEAR it arciong inside ;-)
[05:57:32] <MattyMatt> :)
[05:57:44] <MattyMatt> 325V = 230V rectified?
[06:03:46] <MattyMatt> I might hack one of these into a 10 wire, so I can play around with other styles of driver, but most of the available ones are penta-wired now, so maybe that's the best option in the end
[06:04:21] <MattyMatt> star wired is the simplest to drive tho
[06:04:36] <MattyMatt> and the easiest to understand
[06:09:52] <Loetmichel> MarkusBec: right
[06:09:55] <Loetmichel> grrr
[06:09:58] <Loetmichel> MattyMatt
[06:10:49] <Loetmichel> but isolatet (tisolation transformer in between)
[06:11:00] <Loetmichel> its a nicke room heater btw ;-)
[06:11:04] <Loetmichel> nice
[06:17:42] <MattyMatt> my mill is made of wood
[06:18:00] <MattyMatt> so gotta be a bit careful with the hot stuff :)
[06:20:59] <MattyMatt> I heard the guy who invented starlite died last year, taking his secret to the grave (allegedly). I bet he gave it to the military tho.
[06:24:22] <Jymmm> http://www.youtube.com/watch?v=W4nnLP--uTI
[06:25:48] <Valen> I did wonder what that stuff was
[06:26:05] <Valen> were its temperature claims ever verified?
[06:26:06] <Jymmm> http://en.wikipedia.org/wiki/Starlite
[06:28:22] <Valen> lazer doesn't = actual temperature though
[06:28:50] <Valen> laser
[06:29:20] <Jymmm> 10,000 degrees Celsius
[06:29:31] <MattyMatt> blowtorch is hot, even in the hands of a TV presenter
[06:29:40] <Valen> 1200C isn't that hot
[06:29:47] <Valen> aerogel would do that
[06:30:12] <Jymmm> add a zero
[06:30:12] <Valen> he should have just started selling the stuff
[06:30:14] <MattyMatt> yeah I'm assuming that stuff turns into an aerogel when it's baked
[06:30:36] <Valen> blow torch isnt 12,000 degrees
[06:30:42] <Jymmm> laser is
[06:30:49] <Valen> and a laser doesn't actually have a temperature
[06:31:20] <Valen> if you shine the laser at a mirror what is its "temperature"
[06:31:21] <Jymmm> oh, is THAT why my laser has 5 fans?
[06:31:40] <Valen> photons don't have a temperature
[06:31:43] <Valen> they carry energy
[06:31:54] <Jymmm> yes dear
[06:32:17] <Valen> the targets absorption and dissipation of said energy makes things hot
[06:32:29] <Jymmm> anything you say dear
[06:32:46] <Valen> if his stuff is reflective or highly dissipative, then it wont be 10,000C on its surface now will it?
[06:33:00] <Valen> dear
[06:33:10] <Jymmm> whatever you say dear
[06:33:28] <Valen> Jymmm: you go measure the temperature of your laser beam then mmkay
[06:33:39] <Jymmm> I have
[06:34:09] <Valen> I bet you haven't
[06:34:21] <Jymmm> I bet you I have
[06:34:29] <Valen> please enlighten me
[06:34:58] <Jymmm> laser power meter
[06:35:13] <Valen> giving you a wattage i presume?
[06:36:11] <Jymmm> the meter gave wattage and other things
[06:36:37] <archivist> wattage <> temperature
[06:37:13] <Valen> how hot is 500W?
[06:37:44] <archivist> how big is the heatsink
[06:37:55] <Valen> according to Jymmm it doesn't matter
[06:38:01] <archivist> he dummmm
[06:38:06] <Valen> his light has a temperature
[06:38:37] <archivist> well a colour temperature maybe
[06:38:38] <Valen> white light has a "temperature" i spose
[06:38:42] <Valen> yeah
[06:38:54] <Valen> but laser is a single wavelength, not a blackbody radiator at all
[06:40:51] <Valen> http://www.telegraph.co.uk/technology/5158972/Starlite-the-nuclear-blast-defying-plastic-that-could-change-the-world.html
[06:41:04] <Valen> " It wasn't clear how Starlite worked: was it diffusing the heat? Absorbing it? Repelling it? "
[06:45:42] <MattyMatt> it seems crazy that it could disappear without a trace, but then you hear about NASA grinding Hubbles mirror wrong while in the very next room the DoD were grinding almost identical ones correctly and they never helped
[06:46:59] <Valen> you know the cause of that was a paint chip right ;->
[06:47:06] <Valen> that and not testing it
[06:47:10] <Valen> that was the dumb part
[06:47:47] <MattyMatt> not a paint chip, a slip of cardboard used to protect the anvil of the measuring jig
[06:48:03] <Valen> different to what i heard
[06:48:07] <MattyMatt> and they thought they were testing it, I guess
[06:49:35] <Valen> A commission headed by Lew Allen, director of the Jet Propulsion Laboratory, was established to determine how the error could have arisen. The Allen Commission found that the main null corrector, a device used to measure the exact shape of the mirror, had been incorrectly assembled—one lens was wrongly spaced by 1.3 mm.[56] During the polishing of the mirror, Perkin-Elmer had analyzed its surface with two other null correctors,
[06:49:39] <Valen> http://en.wikipedia.org/wiki/Hubble_Space_Telescope#Flawed_mirror
[06:52:33] <Valen> (a 25 MHz radiation hardened Intel 486 with two megabytes of RAM)
[06:53:18] <Valen> damn now that's the sort of computer that runs hubble and you whinge when your quad core can't play flash videos smoothly because of all the other flash ads
[06:57:37] <MattyMatt> crazy, well if the MoD are listening, I'd still like a bucket of Starlite to paint my wooden mill. I promise not to give any to the russians
[07:01:06] <MattyMatt> I did the opto-bypass on my mill's chinese tb6560 board, it must be a different model they're not wired the same. time to trace the tracks myself
[07:02:15] <MattyMatt> there's a few resistors need removing while I'm at it, the output of the 74hc14 buffers can go straight into the tb6560
[07:05:17] <MattyMatt> these boards are pretty dreadful design. I'm half tempted to take the chips off and start again
[07:08:15] <MattyMatt> can a PC parport reliably drive a PC817 opto over a 6ft cable without needing buffers?
[07:11:29] <MattyMatt> ah I don't care. slow optos can bite me. the pc came from dump and the driver might be headed that way. as long as the cable doesn't melt I don't care if it dumps the motor volts+emf right through it
[07:12:47] <MattyMatt> I'll lurk on ebay.de for some pre-loved vexta drivers
[07:13:32] <Loetmichel> i dont use optos as well
[07:13:55] <Loetmichel> i just plug a driver in between PC and stepper board
[07:14:16] <MattyMatt> powered by the PC 5V?

[08:37:11] <archivist> !wench learn er collet dimensions is
http://www.rego-fix.ch/eng/katalog/ti/ti_fs.htm
[08:37:11] <the_wench> I have learned er collet dimensions is
http://www.rego-fix.ch/eng/katalog/ti/ti_fs.htm
[08:45:10] <djdelorie> ER collets are *always* 8 degrees?
[08:46:15] <djdelorie> looks like making an ER holder is just "drill a hole, bevel the inside, thread the outside" ?
[08:46:55] <Valen> wouldn't off the shelf driver /isolation boards be relativley cheap?
[08:47:14] <Valen> for parallell port
[08:47:23] <djdelorie> only if there's enough demand for them
[08:47:44] <Valen> I imagine there would be enough for somebody in china to turn out a few thousand of em
[08:48:32] <djdelorie> is there enough demand for us to design one as open hardware?
[08:48:59] <Valen> open hardware doesn't really work
[08:49:08] <Valen> there are innate costs and tools involved
[08:49:17] <djdelorie> it works, it just doesn't do what *you* want :-)
[08:49:35] <Valen> if you say so
[08:49:57] <djdelorie> I mean, I could design it and build a handful for me and "my friends", and publish the designs. Then anyone else who wanted one could build one or have one built
[08:50:05] <Valen> sure you could
[08:50:05] <djdelorie> including the Chinese ;-)
[08:50:14] <Valen> or people could spend $30 and buy one
[08:50:27] <djdelorie> if you can find a $30 one, go for it. If you can't...
[08:51:05] <djdelorie> now, a DB25 surge/emi supressor would be relatively easy...
[08:51:15] <Valen> sb25 opto board is easy too
[08:51:34] <Valen> https://probotix.com/breakout_boards/pbx-rf_isolated_breakout_board/
[08:51:37] <Valen> db254
[08:51:39] <Valen> ffs
[08:51:42] <Valen> db25
[08:52:13] <Valen> 2nd result for "parallel port opto isolator board"
[08:52:13] <djdelorie> that's a digital isolator, even better
[08:52:26] <archivist> djdelorie, that company invented er collets according to some site I found that link from
[08:52:51] * djdelorie wonders if my machining skills are good enough to make a collet holder for my lathe
[08:53:19] <archivist> djdelorie, they are cheap to get chinese holders
[08:53:36] <djdelorie> except my 1922 lathe has a 1-7/8 x 8 thread
[08:53:42] <djdelorie> very rare
[08:54:04] <archivist> use the morse taper in the spindle
[08:54:09] <Valen> a full set of collets is something like $50 in ER23 i think
[08:54:39] <djdelorie> My machinist friend told me to avoid using the MT4 for anything but work-between-centers, to avoid wearing out or damaging the taper
[08:55:06] <archivist> ! for an old beast like that!
[08:55:21] <djdelorie> a not-replacable-not-repairable spindle on that beast
[08:55:46] <archivist> anything is replaceable with care and moneyz
[08:55:47] <Valen> I'd be tempted to put something in it and leave it there, do all your work in the collets
[08:55:59] <Valen> put a collet chuck in if thats what you want
[08:56:24] <djdelorie> I figured I'd need to learn to turn inside threads *anyway*, so...
[08:56:41] <archivist> epay like 220733937400
[08:57:07] <djdelorie> http://www.ebay.com/itm/ER32-MT4-Collet-Chuck-/310178351444
[08:57:27] <archivist> well cheap
[08:57:27] <Valen> yup one of those
[08:57:42] <djdelorie> something to worry about *after* I figure out how to add a Z axis to the carriage :-)
[08:58:02] <Valen> vertical milling table?
[08:58:04] <Valen> we have one
[08:58:07] <Valen> its a pita
[08:58:13] <djdelorie> that fits in a 1922 southbend lathe :-)
[08:58:22] <archivist> you can get them with parallel shafts to make spindles with
[08:58:26] <djdelorie> better than "I have no milling machine" though :-P
[08:59:04] <archivist> right angle plate on the carriage and then you do have a mill on the lathe
[08:59:18] <djdelorie> although I haven't tried milling in my new drill press yet, the old one wasn't sturdy enough. Need to see if I have a drawbar hole for it.
[08:59:39] <djdelorie> right, usually folks add a screw/slider type thing on it
[08:59:55] <archivist> morse does fall out when milling, draw bar is a must have
[09:00:21] <djdelorie> http://www.micromark.com/Mini-Lathe-Milling-Attachment,8184.html
[09:00:27] <archivist> this is experience talking :)
[09:00:55] <Valen> morse falls out when drilling half the friggin time
[09:01:38] <djdelorie> checked, no drawbar in the drill press :-P
[09:02:16] <djdelorie> something like
http://www.amazon.com/Taig-T-1220-1220-Milling-Attachment/dp/B003YM8D6Y but I'd have to see how it attached
[09:02:58] <archivist> or home brew something like that ish
[09:03:00] <djdelorie> (and possibly bigger, it's a 13" lathe)
[09:03:35] <archivist> scrap yard run for a slide/bits off something
[09:04:13] <djdelorie> maybe. Not a priority at the moment ;-)
[09:05:41] <archivist> I just ordered some bearings for an er holder type spindle and the silly supplier sent sealed not shielded!
[09:06:18] <Valen> archivist: whats the difference?
[09:12:54] <djdelorie> grizzly has a bunch of compound slide tables in the $120 range, I could cut one in half ;-)

[10:32:31] <alex4nder> hey
[10:33:42] <ReadError> mornin
[10:34:17] <alex4nder> how's it going?
[10:34:50] <ReadError> good
[10:35:05] <ReadError> is it normal for a bit of 'cog' to be on the lead screws?
[10:36:10] <alex4nder> are thesteppers attached?
[10:36:39] <ReadError> nope
[10:36:57] <ReadError> but its on all the axis
[10:38:40] <alex4nder> which one and how are you turning it?
[10:39:55] <ReadError> just with my hand
[10:40:01] <ReadError> the x axis
[10:40:07] <ReadError> its not a hard cog
[10:40:18] <ReadError> but a bit of resistance then it goes
[10:40:28] <ReadError> like turning a stepper but not as hard
[10:40:28] <alex4nder> it's probably fine.. maybe you're just feeling the gibs/ways drag
[10:44:15] <ReadError> whats good for cleaning oil off my accessories
[10:44:19] <ReadError> bucket of gas?
[10:44:26] <ReadError> my blocks and square
[10:44:53] <Jymmm> charcoal lighter fluid removes lithium grease
[10:45:02] <alex4nder> ReadError: how much oil is on there?
[10:45:16] <ReadError> alex4nder: just on my square and 1-2-3 blocks
[10:45:19] <ReadError> not the machine
[10:45:23] <alex4nder> but how much
[10:45:29] <ReadError> like a decent coating
[10:45:32] <alex4nder> because you don't want to remove it if it's a light coat
[10:45:36] <ReadError> enough to cover your hands when you pull it out
[10:45:36] <alex4nder> that shit will rust instantly
[10:45:44] <alex4nder> just wipe it off with a soft rag
[10:45:49] <alex4nder> and leave most of it on there
[10:45:50] <ReadError> the 1-2-3 blocks are bad
[10:45:59] <ReadError> they are like floating in it almost
[10:46:11] * alex4nder shrugs.
[10:46:38] <alex4nder> humidity is a iller
[10:46:40] <alex4nder> +k
[10:46:52] <ReadError> oh for sure
[10:47:01] <ReadError> i have a de-humidifier in my workshop i can turn on
[10:48:59] <ReadError> resistor options i have, 3.9k and 4.7k
[10:49:10] <ReadError> but not much in between
[10:49:17] <ReadError> i could combine another with the 3.9
[10:51:03] <joe9> any feedback on this gcode program:
http://codepad.org/DkzM6a7D
[10:51:08] <joe9> please?
[10:51:25] <ssi> ReadError: is it oil or cosmoline?
[10:51:41] <ssi> if it's light oil, just wipe it off
[10:51:48] <ssi> if it doesn't wipe easily, try WD-40
[10:51:53] <ssi> WD-40 takes cosmoline off like nobodys' business
[10:53:46] <ReadError> oh wow joe9
[10:53:50] <ReadError> you have a coolant setup?
[10:55:25] <joe9> ReadError: no, i don't
[11:01:24] <joe9> G20 G10 L1 P1 Z1 R0.5
[11:01:32] <joe9> (tool length offset = 1 inches and radius of cutter bit = 0.5 inches)
[11:01:48] <joe9> is the above command a good way of setting the tool length offset and cutter radius/
[11:02:25] <joe9> cradek: any thoughts, please?
[11:03:21] <cradek> not sure what you're asking - yes that's how you can set entries in the tool table
[11:04:10] <joe9> cradek: would you consider this good gcode?
http://codepad.org/2cyD82aV
[11:04:33] <cradek> um do you have a more specific question?
[11:05:04] <joe9> cradek: instead of trying to use the tool.tbl, I want to set the tool parameters in the gcode itself in the top of the program.
[11:05:17] <joe9> i want to check if G20 G10 L1 P1 Z1 R0.5
[11:05:23] <cradek> ok
[11:05:27] <joe9> this takes effect when a G41 is used.
[11:05:34] <joe9> and P1 corresponds to D1?
[11:05:50] <cradek> g41 does cutter radius comp. to use the length offset you need g43.
[11:06:25] <joe9> the R0.5 -- isn't that the cutter radius comp.?
[11:06:45] <cradek> that's the radius for the tool table, yes
[11:07:14] <joe9> is that stored in D1, so that value can later be used by G41?
[11:07:35] <joe9> i am trying to figure out where the D1 value comes from.
[11:07:38] <cradek> it's stored in the tool table
[11:07:59] <cradek> http://linuxcnc.org/docview/html/gcode.html
[11:08:00] <cradek> go here
[11:08:05] <cradek> click G41
[11:08:16] <cradek> and bookmark that quickref page! it's the best.
[11:11:23] <joe9> cradek: ok, thanks.
[11:51:21] <alex4nder> gents
[11:58:25] <ReadError> PSU works, outputting 47.9v
[11:58:55] <alex4nder> nice
[12:05:23] <alex4nder> so that discussion yesterday got me thinking
[12:05:31] <alex4nder> the mill would be a pretty good coil winder
[12:06:00] <ReadError> hmm yea if you used another motor?
[12:06:03] <ReadError> or the spindle?
[12:06:12] <ReadError> another motor you could count the turns i suppose
[12:06:22] <alex4nder> yah, I'd use a stepper to control the rate a bit better
[12:06:52] <alex4nder> and since I already have an extra one, and an open channel on the G540.. score
[12:07:08] <ReadError> i love the vids where they are cutting threads
[12:07:35] <alex4nder> http://www.andern.org/alexander/images/coilwinder/spool_holder.jpg
[12:07:46] <alex4nder> that's going to chuck up into the spindle, to act as the source wire spool
[12:08:01] <alex4nder> http://www.andern.org/alexander/images/coilwinder/cone.jpg <- I milled those guys to center the source spool
[12:09:17] <archivist> we did have a user doing coil winding on emc
[12:09:52] <alex4nder> archivist: how did he configure his 'winder' axis?
[12:10:10] <alex4nder> treat it like some sort of rotary table?
[12:10:47] <archivist> worth a look in the mail archives, iirc he chucked pics up on his blog
[12:11:10] <archivist> or irc archives
[12:11:25] <alex4nder> cool
[12:13:44] <archivist> not in my log on this box so before 2010
[12:15:22] <archivist> his nick was mr_boo
[12:16:20] <archivist> mid september dunno the year as xchat was not logging the year
[12:18:44] <archivist> bah he no longer has the image on his site
[12:19:19] <archivist> old url I found in my logs
http://www.carmi.se/misterstarshine/img/DSC00217.JPG
[12:19:35] <alex4nder> yah
[12:19:38] <alex4nder> well cool
[12:19:58] <alex4nder> the only thing I haven't looked into yet is how I'm going to configure axis A
[12:21:07] <IchGuckLive> hi all around the globe !
[12:21:29] <IchGuckLive> 30Deg Celsius in LA today Whow
[12:21:36] <alex4nder> what're you doing in LA?
[12:22:02] <pcw_home> baking?
[12:22:31] <archivist> alex4nder, iirc the spindle has the coil and your source should freely give off the wire
[12:22:31] <IchGuckLive> im not there sitting in germany april wether with Snow Rain Sun ant thunder in one Day B)
[12:23:11] <alex4nder> archivist: in my case the spindle is going to hold the source, the spindle's motor is going to stay off, but provide needed drag
[12:23:40] <alex4nder> and I'm going to mount the stepper doing the actual winding on the table
[12:23:42] <archivist> I assume very thick wire then
[12:23:54] <alex4nder> it's not that much drag
[12:24:13] <pcw_home> IchGuckLive: like they say in the midwest if you dont like the weather, wait 5 minutes
[12:24:34] <archivist> the rotational inertia of the spindle is not needed and may snap the wire
[12:25:04] <alex4nder> I don't think it's going to be a problem.
[12:25:13] <alex4nder> but I'll let you know how it works out
[12:25:28] <IchGuckLive> pcw_home: anchorage alaska is the best to do this
[12:25:34] <archivist> alex4nder, usually coil winders pull through a couple of washers with felt to provide a little friction
[12:25:48] <alex4nder> archivist: yah, I've seen that, that might be the next step
[12:26:04] <alex4nder> but right now I've got something basic that will chuck into a 1/4" collet
[12:26:25] <archivist> for thinner wires the pull off the side of the reel and dont rotate it at all
[12:26:35] <pcw_home> Never been to Alaska but would like to some day
[12:26:54] <IchGuckLive> pcw_home: by bicicle is great
[12:27:23] <IchGuckLive> or bike
[12:27:33] <IchGuckLive> Harley is not good
[12:28:12] <IchGuckLive> to mutch gravel
[12:28:40] <pcw_home> Ive done a few centuries on bikes in my younger days but I'm not up to it anymore
[12:29:02] <IchGuckLive> pcw_home: witch state ?
[12:29:07] <IchGuckLive> you live
[12:29:56] <pcw_home> CA
[12:30:30] <IchGuckLive> nice its warm there today
[12:31:17] <alex4nder> it's like 70 degrees here in Santa Barbara
[12:31:30] <pcw_home> Yeah the last two days have finally gotten warm here
[12:31:59] <IchGuckLive> if been in the first Februar week in Torrance, CA 90501
[12:32:11] <pcw_home> probably do some gardening this weekend
[12:33:04] <alex4nder> nice
[12:33:12] <alex4nder> it's almost time to hit the hills on the motorcycle
[12:33:19] <alex4nder> not too hot yet
[12:33:35] <pcw_home> I'm about 400 miles north of Torrance
[12:33:45] <IchGuckLive> i shoudt have meet some of you guys but i managed only cheescake factury on my todo list
[12:34:27] <pcw_home> well cheesecake sounds pretty good
[12:34:41] <alex4nder> pcw_home: you in santa cruz?
[12:34:58] <IchGuckLive> big bang theory where they all eat ineeded to do so
[12:35:22] <pcw_home> No, SFBA
[12:35:25] <alex4nder> ah
[13:04:33] <ReadError> hey alex4nder
[13:04:39] <ReadError> got a copy of your configs handy?
[13:37:14] <ReadError> stardard or enhanced parport?
[13:43:37] <ReadError> max jitter, ~50k ns
[13:43:39] <ReadError> acceptable?
[13:43:55] <DJ9DJ> namd
[13:43:57] <ReadError> thats on servo, base thread is 16k
[14:00:02] <alex4nder> ReadError: the configs are somewhere.. not sure where
[14:11:22] <ReadError> well this is no good
[14:11:27] <ReadError> fan on my video card died
[14:16:34] <MattyMatt> is it embedded in the heatsink?
[14:17:12] <ReadError> yea
[14:17:23] <ReadError> it happened right after i installed the nvidia drivers
[14:17:35] <ReadError> probably unrelated, since even before post it wont spin
[14:17:54] <MattyMatt> I had one like that on a GF4 so I gutted the fan parts out and glued a normal fan over the hole
[14:18:34] <MattyMatt> it takes 2 slots now, but it's worked for years since then
[14:18:58] <ReadError> i have 2 extra AGP cards
[14:19:16] <ReadError> but that does me no good
[14:19:33] <ReadError> and i dont think this PSU will support this ATI 6870
[14:20:00] <MattyMatt> ah bleeding edge stuff
[14:20:18] <ReadError> lol
[14:20:19] <MattyMatt> got a spare fridge? :)
[14:20:31] <ReadError> i got a beer fridge ;)
[14:23:56] <MattyMatt> I've got a dehumidifier I want to convert into a PC cooler, but for some reason it won't work. it makes the right noises and I cleaned the radiator, but it doesn't get cold
[14:24:57] <Loetmichel> no freon/butane left in device?
[14:25:18] <MattyMatt> the pump wouldn't make the right noise if it was dry
[14:25:34] <Loetmichel> dry?
[14:25:57] <Loetmichel> no, there is no liquid inside... until the conpressor starts to work
[14:26:01] <MattyMatt> yeah they're usually immersed in the working fluid
[14:26:28] <Loetmichel> that is a GAS
[14:26:32] <MattyMatt> ah
[14:26:43] <Loetmichel> it only gets fluid if compressed
[14:27:31] <MattyMatt> I thought it was the other way round. only a gas temporarily between the expansion chamber and the radiator
[14:29:19] <Loetmichel> depends on the amount of gas inside ;-)
[14:30:38] <MattyMatt> well I shouldn't admit publically I know a dehumidifier is just a fridge, or else I might be culpable for regassing it myself :)
[14:30:56] <Loetmichel> and if the pressure in the system gets TO low it will not be compressed enough to liquify before the needle valve
[14:31:53] <Loetmichel> if you use butane: why not?
[14:32:45] <MattyMatt> gott alet the old stuff out first :)
[15:06:44] <olivius67> Hi All :)
[15:08:59] <olivius67> I'm trying to setup an ebay stepper driver using stepconf, this card requires an enable signal for each axis. For instance pin14 of the parallel port should be used as 'x enable'. However, I don't see this option in the setpconf select box for any pin. Any idea?
[15:09:15] <cradek> "amp enable"
[15:09:54] <olivius67> amplifier enable?
[15:09:59] <cradek> yes
[15:10:07] <olivius67> what does it means?
[15:11:18] <cradek> that is the signal that goes true when linuxcnc wants the servo amps/stepper drivers to be enabled
[15:11:48] <archivist> or set to false on an emergency stop
[15:12:07] <olivius67> ok, thx guys :-)
[15:12:11] <olivius67> trying now...
[15:14:34] <olivius67> ouch...
[15:16:02] <olivius67> looks like I'm not going to test my axis right know:
http://pastebin.com/Fzq4n3qY
[15:16:58] <archivist> olivius67, have you done any latency tests yet
[15:17:08] <olivius67> actualy no
[15:17:25] <olivius67> guess what? when I tried it, it simply didn't launch
[15:17:40] <olivius67> do you know the cml to call the prog in terminal
[15:17:45] <olivius67> so that I can check the errors
[15:18:34] <archivist> latency-test
[15:18:43] <olivius67> thx
[15:19:23] <olivius67> insmod: error inserting '/usr/realtime-2.6.32-122-rtai/modules/rtai_hal.ko': -1 Operation not permitted
[15:20:57] <olivius67> does this inspires someone?
[15:21:27] <archivist> not me
[15:21:46] <alex_joni> olivius67: check dmesg
[15:21:54] <alex_joni> there should be a reason for that
[15:22:19] <archivist> are you using the live cd or are you building yourself on some odd OS
[15:22:49] <olivius67> live cd install
[15:23:03] <olivius67> no error logged in dmesg when I tail -f it
[15:23:13] <cradek> pastebin your full dmesg
[15:26:43] <olivius67> http://pastebin.com/WvTkLRzP
[15:27:53] <cradek> no APIC, boot with the "lapic" boot parameter to force-enable it.
[15:28:08] <olivius67> ho yes
[15:28:19] <olivius67> how can I make it permanent?
[15:29:04] <cradek> http://www.google.com/search?q=lapic+linuxcnc
[15:29:22] <cradek> click first hit
[15:29:28] <cradek> brb
[15:30:32] <olivius67> yup, done, rebooting... brb
[15:38:05] <alex4nder> hey
[15:38:41] <ReadError> ok so i swapped the 6870 into the hackintosh
[15:38:50] <ReadError> pulled the 5770 out for linuxcnc
[15:40:19] <DJ9DJ> gn8
[15:42:31] <alex4nder> ReadError: damn.. going upscale
[15:48:18] <ReadError> lol
[15:48:20] <ReadError> well
[15:48:31] <ReadError> it was that or spend like $30 on a new one
[15:48:52] <ReadError> 50k on servo, 16k ns on base
[15:48:54] <ReadError> acceptable?
[15:49:35] <ReadError> brb getting some mobil1 and a box
[15:50:03] <alex4nder> ReadError: kinda shitty
[15:50:05] <alex4nder> really
[15:50:11] <ReadError> aw ;(
[15:50:22] <ReadError> will it work if i go slow?
[15:50:28] <cradek> nothing at all wrong with 16k
[15:50:29] <ReadError> until i get an atom board builtup
[15:50:52] <cradek> anything under 20-25 is a fine result for most setups
[15:52:34] <alex_joni> ReadError: remember to really abuse it during the test
[15:55:44] <alex4nder> ReadError: my Pentium 3 that I pulled out of the trash gets 19k and 25k..
[15:55:48] <alex4nder> for comparison
[15:56:13] <olivius67> cradek: lapic fixed my prob, thx :-)
[15:56:14] <alex4nder> under as much loads it will take, while remaining the slightest bit responsive.
[15:56:48] <cradek> yay
[16:30:15] <r00t4rd3d> hey what does "1 Start" mean for nuts
[16:30:29] <r00t4rd3d> 3/8-16 1 Start
[16:30:52] <djdelorie> it means there's one thread that goes around, so once around advances you one thread
[16:31:07] <djdelorie> on a four start, once around moves you *four* threads across
[16:31:41] <r00t4rd3d> ahh okay, ty
[16:33:29] <archivist> pcw_home, what's the polite way to tell people not to short stuff to test ! relay driver not working thread
[16:34:28] <joe9> how do i specify linuxcnc to load a particular gcode file at startup?
[16:34:48] <joe9> i could not see an entry in ~/.axis_preferences or ~/.linuxcnc
[16:35:01] <joe9> i use the axis GUI
[16:46:18] <ReadError> anything that can be done to lower the response?
[16:46:28] <joe9> you mean latency?
[16:47:56] <ReadError> yea
[16:48:39] <joe9> a lot..
http://codepad.org/yXnzr7TG
[16:49:42] <ReadError> strange i did the software update and it wiped out the linux cnc menu
[16:49:47] <ReadError> guess i need to reinstall it
[17:19:10] <robh__> how did u find mach archivist
