[01:12:49] <theos> hi
[01:13:21] <theos> does rtai only enables 1 core? or all cores work?
[01:14:09] <psha> all (less then 16 or something like this)
[01:14:11] <psha> or 8
[01:14:13] <psha> don't remember
[01:14:39] <theos> thanks
[01:32:47] <Loetmichel> *yawn* Mornin'!
[01:34:33] <theos> monin
[01:35:55] <Loetmichel> a. running on "auto", waiting for the fiurst coffee of the day to sink in ;-)
[01:37:14] <theos> :)

[07:03:52] <pingufan> Hello. I have a question on better understanding the usage of g38.2 command. Do I have to switch off tool length compensation at the end of a milling job? I changed (manually) the tool back to the first one, then did touch off. The program initially sendes then the tool length and then Z-Axis was ~ 4mm too deep. (Length difference to last tool). Currently I only tund off tool length compensation at the beginning of my job. When I start
[07:03:54] <pingufan> the program, stop it, and then touch off, it works correctly.
[07:05:05] <jthornton> x?
[07:05:22] <jthornton> are you still using 2.3.x?
[07:06:20] <pingufan> Yes. Had no time to switch until now.
[07:06:36] <Valen> damn chinese
[07:06:47] <pingufan> But I hope I can do it within next 7 days.
[07:06:49] <Valen> our spindle had a pair of angular contact bearings in it
[07:06:55] <Valen> but they were both in the same way
[07:06:59] <Valen> and they had no spacer
[07:07:44] <Valen> so they couldn't be tightened against each other
[07:07:51] <pingufan> Is this a bug of version 2.3.x ?
[07:08:05] <jthornton> pingufan: you might want to warn people your using a very old version as they might assume your using a current version and give you the wrong answer
[07:08:57] <pingufan> You are right. :)
[07:09:15] <jthornton> dunno, you would have to look up what was fixed since 2.3.x
[07:10:36] <jthornton> I would have to assume that when the probe is tripped the current coordinates are stored which would include all offsets
[07:11:07] <jthornton> but you might do some experiments to verify how 2.3 works
[07:11:14] <pingufan> Does the new one also do the touchoff of the tooltip sensor with user coordinates (G54) ? It is a bit problematic with my current one to do the touchoff with machine limits when workpieces have different height. I cannot define z0 and also cannot put G53 in front of G38.2.
[07:13:00] <jthornton> change to an unused coordinate system before the probe move then change back???
[07:13:28] <jthornton> I know in 2.4 I do that before presetting a tool
[07:14:07] <pingufan> I will now try to put also G49 in at the end of a job, so tooltip compensation is OFF. Then the touchoff should be correct.
[07:15:07] <jthornton> that is a good practice to turn off anything you have turned on at the end of a G code file
[07:15:14] <pingufan> Btw., how fast would you move when milling a PCB? My tool is V-shaped, 10, 0.2 mm, I have ~15000-18000 rpm.
[07:16:09] <pingufan> I currently use 40 mm/min, this is awfully slow. Before, I used 100mm/min and this broke the tip.
[07:16:35] <jthornton> I've never milled a PCB, but you have some good data now to base your decisions on
[07:17:26] <pingufan> :D This experience did cost 5 Euro.
[07:18:44] <Valen> i have milled a pcb
[07:19:27] <Valen> pingufan: look around for cheap v tips you should be able to find them for ~$1 or less
[07:19:54] * cpresser milled PCBs with 800mm/min. it greatly depends on the used tool and how flat your really pcb is :)
[07:20:01] <pingufan> With 1/8" shaft?
[07:20:09] <Valen> the flatness is the main thing
[07:20:26] <Valen> also the acceleration of your mill will affect top speed
[07:21:05] <cpresser> pingufan: http://www.virtualvillage.com/pack-of-5-carbide-engraving-bits-40-degree-0-2mm-diameter-007807-227.html
[07:21:32] <pingufan> Indeed. Because mine are not very flat, I have to mill 0.3mm deep (to be sure to be through the copper. Therefore I use this extremely small angled tools with only 10 to still get a slim path.
[07:21:37] <cpresser> really cheap chinese stuff. there are okay for doing a board once in a while; but not for 'real production'
[07:21:58] <cpresser> use this: http://phk.freebsd.dk/CncPcb/
[07:22:16] <pingufan> Where is VV located?
[07:22:45] <pingufan> I don't think they ship for free to Austria from USA.
[07:22:53] <Valen> we made ours flat with a vaccume cleaner
[07:23:07] <Valen> pingufan: that will drastically affect the life of your tips
[07:23:16] <Valen> we use 45 degree
[07:23:45] <pingufan> Yes. This angle will surely let them last much longer. :)
[07:24:01] <pingufan> Moment, must replace tool...
[07:24:02] <jdhnc> there is some python height probing code out there that you can use to post-process pcb-gcode output
[07:24:04] <Valen> we put the board on a box and pulled the vacuume under the box
[07:24:06] <cpresser> pingufan: they ship worldwide. its cheap stuff from china. but you will find similar offers on ebay.
[07:24:30] <Valen> with a bunch of small holes in the box to suck the pcb down,
[07:24:37] <Valen> a line of tape around the outside and its all good
[07:24:43] <Valen> perfectly flat
[07:25:06] <jdhnc> assuming the pcb material is flat to begin with.
[07:25:22] <Valen> generally the thickness is pretty good
[07:25:25] <Valen> but they are bowed
[07:25:51] <pingufan> I currently buy in Vienna from CNC-Heiz. 10 minutes from me.
[07:26:12] <pingufan> But this is no carbide one.
[07:26:39] <pingufan> You use a normal vacuum cleaner?
[07:26:49] <Valen> http://www.vapourforge.com/jake/temp/IMAG0117.jpg
[07:27:14] <Valen> we have an industrial one thats meant to be ok running for a while blocked off
[07:27:21] <Valen> but we also did it with a $20 one ;->
[07:27:22] <pingufan> Beautiful!
[07:27:37] <cpresser> nice milling!
[07:27:39] <pingufan> And the Gcodes come from where? Eagle CAD?
[07:27:46] <Valen> kicad + pcb2gcode
[07:28:02] * Mjolinor depressed now, why don't my PCBs look like that
[07:28:07] <Valen> made this too http://www.vapourforge.com/jake/temp/IMAG0135.jpg
[07:28:19] <Valen> that was harder lol
[07:28:33] <Valen> out of this http://www.vapourforge.com/jake/temp/IMAG0136.jpg
[07:29:08] <Valen> i'm just going to rename all those images lol its pissing me off
[07:30:15] <pingufan> My ones look similar, but I must increase lifetime of my tools. :)
[07:30:41] <Valen> http://www.vapourforge.com/jake/temp/milled-pcb-for-spinzster.jpg http://www.vapourforge.com/jake/temp/milled-soldermask-for-spinster-aluminium.jpg http://www.vapourforge.com/jake/temp/milled-soldermask-for-spinster-printed.jpg
[07:30:45] <Valen> there we go
[07:31:35] <Valen> i think that was our second attempt
[07:31:44] <Valen> Mjolinor: why dont yours look like it?
[07:32:03] <Mjolinor> they are getting there :)
[07:32:32] <Mjolinor> slow process of experimenting with speeds and feeds mainly
[07:32:44] <pingufan> Cool. Ok, I must leave now. Have a meeting at a customer. Which version should I try? My hardware is a VIA C7 with CN700 graphics. Via EPIA or similar class.
[07:32:55] <Valen> we went through a few tips untill we got it right
[07:33:21] <Valen> version?
[07:34:43] <Mjolinor> http://homepage.ntlworld.com/dknpower/spindle2.jpg
[07:34:48] <Mjolinor> they look like that :)
[07:35:10] <Valen> you might be cutting just a touch deep ;-P
[07:35:16] <Mjolinor> it is
[07:35:20] <Valen> also your RPM may be kinda low for pcbs
[07:35:36] <Mjolinor> its the problem of not flat that makes that necessary
[07:35:48] <Mjolinor> RPMs are OK
[07:36:07] <Mjolinor> anythign above about 15000 seems OK, under that it gets rough round the edges
[07:36:19] <Valen> if it makes 15k thats fine
[07:36:32] <Valen> i usually only see that kind of motor hit 6k
[07:36:36] <Mjolinor> that motor will go to about 35k if I wind it up
[07:36:37] <pingufan> Of linux-cnc. I remember that I had troubles with a newer version while this old one had no problems.
[07:36:45] <Mjolinor> it annoys the wife at that though :)
[07:36:53] <pingufan> Does the new version also power off the PC on shutdown?
[07:36:54] <Valen> Mjolinor: lol
[07:37:01] <Valen> 10.04 will probably work
[07:37:10] <Valen> but no guarantees lol
[07:37:20] <Valen> c7's are kinda old though?
[07:40:05] <pingufan> Currently it is well enough? :)
[07:40:06] <JT-Shop> pingufan: iirc that depends on the hardware
[07:40:53] <pingufan> I can move with up to 1100mm/min with my steppers (with microsteps)
[07:42:32] <pingufan> Ok, shall I try the newest release, or even some kind of "beta" ? I am not really interested in fighting bugs, it should work trouble free.
[07:44:48] <pingufan> Must leave now. Milling was succ3essful.
[07:44:50] <pingufan> Bye.
[07:58:31] <JT-Shop> I need to make some 1/2 scale square nails... any thoughts on how to form the head?
[07:59:04] <Valen> i don't really understand the question lol
[07:59:27] <JT-Shop> the heads of the nails were hammered out somehow
[07:59:34] <mazafaka> JT-Shop: Am I right to think that external Video card (not built in one) is preferable, even being GeFoce 2 MX
[07:59:37] <JT-Shop> it's for my 1/2 scale cannon
[07:59:56] <Valen> use regular nails and file the heads?
[08:00:04] <Valen> i don't know how big a nail you want?
[08:00:18] <mazafaka> JT-Shop: what, have a long-term plan to kill the president? :)
[08:01:07] <JT-Shop> pretty small about 1/8" in diameter
[08:01:52] <Valen> you cant get square head nails in that size?>
[08:02:15] <JT-Shop> maybe at a tack shop, good idea I'll check
[08:03:36] <JT-Shop> http://www.millercountymuseum.org/archives/presidents/100315_14_OldSquareNailsFromLupardusCabinDonatedByCarlMcDonald.jpg
[08:19:04] <Mjolinor> my house is put together with nails like that :)
[08:20:28] <theos> :)
[08:20:47] <theos> you should use screws instead of nails
[08:20:59] <Valen> my house is put together with asbestos
[08:21:03] <Mjolinor> I didn't use the nails, they were here already
[08:21:10] <Mjolinor> and they are absolute dogs to get out
[08:21:12] <theos> hmm
[08:23:27] <Valen> is where the build log will go is what i'm making atm btw
[08:23:30] <Valen> bah
[08:23:39] <Valen> http://www.robowars.org/forum/viewtopic.php?t=1751 is what i'm making at the moment btw
[08:23:57] <Mjolinor> its a roomba
[08:24:18] <theos> roomba is a vac
[08:24:28] <Mjolinor> roomba pretends to be a vac
[08:24:43] <Mjolinor> in actual fact it is an amusing diversion
[08:24:49] <Mjolinor> but not much use as a vac
[08:25:03] <theos> its a decent automatic vac
[08:25:17] <Mjolinor> its good for finding screws on my carpet, thats about all :)
[08:25:29] <theos> :)
[08:25:35] <Mjolinor> carpet being sort of speckled and all colours it is extremely hard to find things you drop
[08:25:42] <Mjolinor> but the roomba does well at that :)
[08:26:01] <theos> http://i565.photobucket.com/albums/ss95/animalswithlightsabers/lightsaber-roomba-cats.jpg
[08:26:29] <Mjolinor> amusing diversion, as I said :)
[08:27:08] <theos> most of the fancy devices thesedays are amusing diversions indeed
[08:27:33] <Mjolinor> true
[08:27:41] <Mjolinor> iphone goes in the same category I think
[08:28:02] <theos> all apple stuff you can say
[08:30:37] <Valen> its a robot wars robot
[08:30:52] <Valen> just has no teeth in the render :-<
[08:30:58] <Valen> the ring around the outside spins
[08:30:59] <theos> :)
[08:31:40] <theos> it is a funny assassin?
[08:34:10] <cpresser> robo-wars looks like fun :)
[08:38:42] <Valen> it is cpresser
[08:39:23] <Mjolinor> expensive hobby
[08:39:28] <Valen> http://www.youtube.com/playlist?list=PLA8C75518EFFFF469 is the latest comp
[08:39:32] <Valen> these are the "toy" robots
[08:39:49] <Valen> i had a junk entry in that lot, dodgybot
[08:39:58] <Valen> part of my robot got stuck into the wall
[08:40:11] <theos> :)
[08:40:16] <Valen> anyway past my bed time
[08:40:32] <Valen> Mjolinor: not paticularly expensive in this weight class (1.3kg)
[08:40:51] <Valen> motors are ~$20 a pair, speed controllers are ~$10 and radios are $25
[08:41:06] <Mjolinor> anyhtign you spend hours of your life making in order to have it smashed to bits is expensive methinks :)
[08:41:23] <Valen> the aim is not to get smashed to bits
[08:41:28] <Valen> its to smash the other guy to bits ;-P
[08:41:35] <Valen> and generally the damage isn't that bad
[08:41:46] <Valen> dodgybot, was just that, dodgy lol
[08:42:05] <Valen> most people build their bots on a kitchen table for around $50 in an hour or 3
[08:43:24] <Valen> and repairs run to a few $
[08:44:29] <theos> ^
[09:03:36] <ssi> morn
[09:06:32] <anonimas1> anyone familiar with fanuc?
[09:08:11] <theos> nop
[09:19:05] <ssi> I need to order some mesa gear today i think
[09:20:53] <theos> has anyone succeeded in running emc2 on damn small linux?
[09:21:03] <theos> i mean linuxcnc*
[09:35:34] <tehDarkAura> why did you pick dsl?
[09:36:13] <theos> i didnt pick it yet. just taking suggestions
[09:37:17] <theos> i have a 440bx board. really old but tough one. it has 64mb ram. and i want to run linuxcnc on it. ubuntu may not run properly on it. so i was thinking i should use a low resource OS
[09:37:50] <ssi> wow that's extremely old
[09:37:52] <ssi> p2, yea?
[09:37:57] <theos> p3 :D
[09:38:07] <tehDarkAura> ahh i see -- unless your trying to get some really old hardware to work id stay away from that distro -- ive never had much luck getting it to do much
[09:38:15] <tehDarkAura> ahh i see
[09:38:57] <theos> puppy linux needs 128mb ram min i guess. i just have 64mb. and the ram it needs to upgrade are too old and costly today :)
[09:39:28] <theos> or would a swap partition make it work properly ?
[09:39:30] <tehDarkAura> :/ yeah i know what you mean i got a few old laptops id like to put to work but its silly when you look at the price for memory
[09:39:31] <ssi> I just bought a G41 chipset motherboard with a 1.89GHz core2duo and 8G of ram as a combo package for $104 :P
[09:40:23] <theos> nice
[09:40:36] <ssi> point is, probably cheaper overall to spend the money
[09:41:01] <tehDarkAura> indeed, youll be happier with the results too im sure
[09:41:03] <theos> i have looked at some nice combo motherboards till 100$. good specs. but i am trying to use an old desktop first
[09:41:48] <ssi> my small lathe is running on a via c3 1GHz ITX board
[09:41:50] <ssi> and it mostly sucks
[09:41:55] <ssi> I'll probably swap it for something better
[09:44:10] <theos> old stuff is like treasure. scarce and costly :/
[09:44:12] <ssi> I can't find any hardinge chucks that are threaded for the HNC
[09:44:16] <ssi> theyr'e all the 4 degree taper style :(
[09:44:39] <theos> :/
[09:46:22] <theos> buy a threading tool :)
[09:47:47] <ssi> erm, not gonna do it that way thx
[09:48:28] <theos> :)
[09:48:54] <theos> such small tools are quite handy
[10:18:44] <AdrianG> hi
[10:18:54] <AdrianG> what can i use to maintain a steady current at 2mA ?
[10:19:24] <jdhnc> a lovely fluke calibrator?
[10:19:49] <cradek> that's called a current source; some examples at http://en.wikipedia.org/wiki/Current_source
[10:20:52] <JT-Shop> ssi: I got a 4 jaw for my CHNC from MSC
[10:21:02] <cradek> but if the load is simple, you don't have to work so hard for it
[10:22:30] <AdrianG> I am trying to build a tDCS
[10:22:34] <AdrianG> to overclock my brainz.
[10:22:53] <cradek> I don't know what that means
[10:22:55] <djdelorie> AdrianG: typically, an LM317 and a resistor
[10:23:12] <AdrianG> cradek: transcranial direct current stimulation
[10:23:15] <AdrianG> 9V at 2mA
[10:23:36] <AdrianG> http://www.nature.com/news/2011/110413/full/472156a.html
[10:24:28] <cradek> fascinating but I struggle to see how it's related to linuxcnc...?
[10:25:18] <AdrianG> its not. i just knew you guys would know about current sources.
[10:25:27] <AdrianG> thx btw.
[10:29:28] <jdhnc> are you sure you want 2 and not 20?
[10:30:53] <AdrianG> why
[10:31:12] <JT-Shop> I'd say a minimum of 48V for proper stimulus, just ask the kind hearted nurse Ratchet
[10:31:31] <AdrianG> you just want me to die.
[10:31:47] <jdhnc> perhaps it is meant to say .2 milliamps
[10:31:48] <JT-Shop> well you must use it in moderation
[10:32:32] <AdrianG> jdhnc: pretty sure it was 2 mA
[10:33:03] <AdrianG> well, that was teh highest current they used i think.
[10:37:20] <djdelorie> for 20 mA you can use NSI45020T1G
[10:40:22] <AdrianG> 20mA is too high.
[10:54:58] <jdhnc> hope he left willingly instead of the convulsions ripping the computer apart
[10:56:07] <theos> he would have pinged out
[10:56:38] <archivist> should have given him a 20A 2kv design :)
[10:56:53] <JT-Shop> lol
[10:57:36] <ssi> JT-Shop: what'd that chuck cost you?
[10:57:38] <archivist> I can be evil sometimes
[10:57:50] <theos> :)
[10:59:31] <syyl> chuck?
[10:59:35] <syyl> chuck norris?
[10:59:53] <ssi> yes, chuck norris
[11:00:09] <syyl> great ;
[11:00:10] <syyl> )
[11:00:22] <ssi> I see a three jaw they carry that's spec'd as hardinge 4 taper
[11:00:27] <ssi> which is what yours has, but not mine :/
[11:00:56] <archivist> you have a lathe..make whatever taper you need
[11:01:18] <ssi> hate cutting backplates
[11:01:19] <ssi> heh
[11:01:28] <ssi> it's a threaded spindle, not a tapered one
[11:01:34] <syyl> everyone who has a lathe hates that job...
[11:01:43] <JT-Shop> ssi: the one I got was a 8" 4 jaw Bison chuck and I made them quote it so I got it at a lower price
[11:01:50] <ssi> gotcha
[11:02:21] <ssi> I'm trying to find details on what exactly the spindle nose thread is
[11:02:26] <ssi> it might be something relatively standard
[11:02:27] <archivist> I re did one of my backplates on the southbend, but after the fixes, still out of true, I need a better chuck
[11:13:54] <ssi> http://www.globalindustrial.com/p/tools/metal-fabrication/Workholding/back-plate-threaded-for-bison-chucks-5-inch-2-3-16-10-hardinge
[11:13:57] <ssi> bam
[11:18:05] <ssi> JT-Shop: I don't guess there's any chinese knockoff tooling for the chucker turrets is there?
[11:18:26] <JT-Shop> I got all mine from flea bay
[11:18:37] <ssi> yea I'm keeping an eye on it
[11:18:40] <ssi> but it's scarce or expensive
[11:19:00] <ssi> I got some tooling from the guy that sold me the lathe, but he had no 5/8" round holders or extension holders at all
[11:19:04] <ssi> I have one of each coming
[11:19:25] <ssi> I may try to manufacture some extension holders, but it's gonna cost me some bux in steel
[11:19:35] <ssi> like the CC18 style ones
[11:20:30] <archivist> time you raided the local scrap yard for steel
[11:20:42] <ssi> I haven't found a decent scrap yard
[11:21:00] <ssi> and I'll probably just buy some 2.5" square 1018 cold roll barstock
[11:21:25] <ssi> probably be $30-40 each worth of steel, but better than paying $175 for CC18s on ebay
[11:22:46] <ssi> http://www.ebay.com/itm/CC-15-3-extension-tool-holder-Hardinge-Omniturn-Haas-/350473120550?pt=BI_Tool_Work_Holding&hash=item5199d36b26#ht_500wt_1378
[11:22:49] <ssi> there's a CC15 3"
[11:24:40] <JT-Shop> when you buy them make sure it has the wedge
[11:25:16] <JT-Shop> I think I've purchased one from him before
[11:25:36] <ssi> I bought one from somewhere else
[11:25:39] <ssi> I hope it has the wedge
[11:25:39] <ssi> heheh
[11:26:25] <ssi> no, I bought this one sry
[11:26:25] <ssi> http://www.flywheelmachinetools.com/Smallemsforsale/HARC15.JPG
[11:26:28] <ssi> that's a non-wedge type
[11:26:32] <ssi> only fits 3/8" tops
[11:27:52] <JT-Shop> not seen that type before
[11:28:05] <JT-Shop> just wedge types missing the wedge
[11:28:08] <ssi> heheh
[11:28:19] <ssi> I think the point of the wedge type is that it'll work on either turret
[11:28:26] <ssi> and with either 3/8" or 1/2" tools
[11:29:17] <ssi> the tools that I got from the guy with the lathe are kinda interesting
[11:29:21] <ssi> mostly C10 holders,
[11:29:37] <ssi> and then some insert toolholders that have the shanks cut off and some 3/8" flatbar welded to them
[11:36:17] <cncbasher> JT-Shop: all mine are wedge type too , those dont have the side screw adjuster , so just single size as you say
[11:36:31] <ssi> cncbasher: you have an HNC or CHNC?
[11:36:42] <cncbasher> chcnc
[11:37:15] <ssi> converted to linuxcnc?
[11:37:16] <cncbasher> i can never remember the type , JT will know
[11:38:10] <cncbasher> yours is the older curved top i think , mine is more square cased with 2 sliding windows
[11:38:30] <cncbasher> and access sliding door on the rear side
[11:39:10] <ssi> yep
[11:39:15] <ssi> mine's the HNC
[11:39:20] <JT-Shop> I think the adjuster wedge is to be able to set the height of different tools but I may be full of it and not know
[11:39:20] <ssi> it's a smaller machine; 5C spindle
[11:40:04] <ssi> who is it that has the youtube channel "DamikMachineLtd"?
[11:40:07] <cncbasher> still running the fanuc controller , till i can find time to actualy have the machine idle to convert it
[11:41:05] <cncbasher> mine takes 16c , but i have the converter for 5c collets and 12 foot barfeed on it
[11:41:22] <ssi> yea I would love to have a chnc, but they tend to be a bit more money than I wanted to spend
[11:41:30] <ssi> and now I guess I no longer have room for one :)
[11:41:46] <cncbasher> yea they do take up some room
[11:43:04] <ssi> I've heard people mention that they had a barfeeder on an HNC... I wonder how hard that is to get ahold of
[11:45:01] <cncbasher> i have not seen any barfeeders this side of the world
[11:45:14] <ssi> which side would that be? :D
[11:45:28] <archivist> north on my world
[11:45:30] <cncbasher> i picked up 2 machines and scrapped one of them
[11:46:13] <cncbasher> archivist : do you get north of watford
[11:46:27] <archivist> Im well north of watford
[11:47:07] <cncbasher> anything my side of leeds you'll need a passport
[11:47:28] <archivist> Im 60 miles south of Leeds
[11:47:57] <cncbasher> or an interpreter
[11:48:45] <ssi> any of you hardinge guys have a wild ass guess as to how much IO I'll need?
[11:48:50] <ssi> think a three port mesa card will be enough?
[11:49:25] <cncbasher> yea 3 port should be fine
[11:49:56] <ssi> I may order that plus a 7i49 today
[11:51:12] <JT-Shop> iirc there are limits, homes, spindle lock and a few others that I connected back up
[11:51:14] <cncbasher> the conversion should be straight forward , the turret may be a pain
[11:52:13] <ssi> does the turret use a resolver?
[11:54:10] <cncbasher> JT will know , i have not had mine apart yet , but i could check on tuesday
[11:56:07] <ssi> yowza the resolver card is high
[11:59:46] <cncbasher> yes but makes the conversion easy
[11:59:50] <ssi> yeah I know,
[11:59:54] <ssi> I'm getting it no matter what
[12:00:02] <ssi> but I'mma gripe about the price, ok? :D
[12:01:31] <JT-Shop> my turret has a absolute encoder sorta thingy
[12:01:45] <JT-Shop> just uses some inputs'
[12:02:46] <cncbasher> so the turret is just grey code encoder
[12:03:11] <JT-Shop> I converted my CHNC with a 5i20 and three daughter cards
[12:03:28] <JT-Shop> yea, I think it is gray code
[12:03:42] <deuplonicus> whats up guys. got my cnc machine up and running over the past couple days
[12:04:14] <deuplonicus> i have 2 motors for my y-axis and it seems like one of the motors is missing steps.
[12:04:17] <JT-Shop> a 7i33 and a couple of 7i37's
[12:05:53] <JT-Shop> ssi: the wiring diagrams for my CHNC is on my web site if you want to gander at them
[12:06:51] <deuplonicus> tried diminishing the accel and velo in the .ini file seemed to fix it when i was jogging the gantry back and forth but when i ran a cut it seemed to act like i never adjusted the .ini
[12:07:00] <JT-Shop> deuplonicus: did you run a stepper test to see if you are losing steps?
[12:07:23] <archivist> deuplonicus, reduce acceleration and/or top speed to improve it
[12:07:38] <JT-Shop> deuplonicus: what trajectory control are you using?
[12:07:42] <deuplonicus> well i ran a couple simple rectangle cuts i was getting un even edges
[12:07:51] <deuplonicus> emc2?
[12:08:08] <JT-Shop> G64 I assume
[12:09:31] <JT-Shop> can you describe "un even edges"
[12:10:14] <JT-Shop> G64 = Best Possible Speed no matter how much off the path you have to go
[12:10:43] * JT-Shop always thought that was a bad choice for the default
[12:11:03] <cradek> if the motor is losing position, I don't see what that has to do with the problem
[12:11:36] <JT-Shop> it only "seems" to be losing steps...
[12:11:57] <cradek> deuplonicus: we need much more information to offer any useful suggestions
[12:12:22] <deuplonicus> yea when the bit makes a second pass through the material it is not over the exact same line. the y axis seems like it is losing steps bc i can feel a "bump" or catch as the gantry moves everyonce in a while.
[12:13:28] <archivist> also check if your stepper/drive is powerful enough for the load
[12:13:34] <JT-Shop> mechanical?
[12:13:48] <deuplonicus> the other motor on the same gantry seems fine. i checked the rack to make sure that it wasnt bumping along something but its fine
[12:13:59] <JT-Shop> do you have backlash compensation?
[12:14:09] <JT-Shop> JT-Shop deuplonicus: did you run a stepper test to see if you are losing steps?
[12:15:03] <jdhnc> what stepper driver?
[12:15:06] <deuplonicus> hmm how do i run a steeper test
[12:15:31] <deuplonicus> *stepper
[12:16:08] <JT-Shop> you have the docs on your computer?
[12:16:22] <JT-Shop> Getting Started > Stepper Diagnostics
[12:16:42] <JT-Shop> or the html is here http://linuxcnc.org/docview/2.5/html/common/Stepper_Diagnostics.html#_testing
[12:18:00] <deuplonicus> sweet i check that
[12:19:14] <JT-Shop> deuplonicus: another good thing to read is http://linuxcnc.org/docview/2.5/html/common/User_Concepts.html
[12:24:16] <cpresser> deuplonicus: http://ca.rstenpresser.de/~cpresser/tmp/pictures/emc2_error.png
[12:24:28] <cpresser> the image-filename is wrong. its not an error, its a feature
[12:24:39] <cpresser> thats what happens with G64 turned on
[12:25:53] <JT-Shop> and depending on the update rate of the back plot that may or may not be the actual path the tool takes but a a good example of G64
[12:26:05] <Jymmm> TURN IT OFF! TURN IT OFF! You're watering down the beer!!!!!!!!!!!!
[12:27:33] <deuplonicus> so should i turn off G64?
[12:28:00] <Jymmm> Unless you happen to LIKE Neer Beer
[12:28:48] <alex4nder> yoh
[12:34:53] <JT-Shop> deuplonicus: you don't turn off trajectory control but pick the one that suits your machine/part
[12:35:31] <deuplonicus> k lol
[12:36:07] <JT-Shop> the second link covers an intro into trajectory control
[12:56:37] <Jymmm> SWPadnos: ping
[13:06:25] <Jymmm> SWPadnos: $10 on sale @ Frys... http://www.youtube.com/watch?v=CxO-_E8uqN4
[13:06:49] <Jymmm> 2AH
[13:10:41] <SadMan> any idea why load in linuxcncrsh isn't working?
[13:16:23] <SadMan> because it's called open, i should learn how to read
[13:22:56] <ssi> JT-Shop: I appreciate it! I have a full set of schematics for the HNC, so that oughta help
[13:30:29] <ssi> so the real question is
[13:30:36] <ssi> should I get a 5i20 or a 5i23
[13:32:47] <cncbasher> ssi: i'd go the 5i23
[13:32:52] <ssi> yea that's what I'm thinking
[13:33:01] <ssi> for thirty bux, extra gates can't hurt :)
[13:33:08] <cncbasher> it's a new part , and also great fpga capaciry
[13:34:00] <cncbasher> with the 7i49 you would have problems with the 5i20 perhaps in capacity
[13:34:08] <ssi> you think?
[13:34:31] <cncbasher> the 5i20 is only a 200 gate part
[13:34:39] <ssi> yeah
[13:34:39] <cncbasher> the 5i23 is 400k
[13:34:50] <ssi> I didn't realize the resolver decoders were that heavy on logic slices
[13:35:17] <cncbasher> i am not sure , but pcw can advise no doubt
[13:36:20] <cncbasher> i have only used the resolvers on a 7I43 , so not sure on the impact on a 5i20 , but i'd recon it's tight
[13:38:40] <ssi> ordered
[13:38:53] <ssi> sad that the mesa gear cost four times as much as the computer :D
[13:39:15] <cncbasher> did you see the pics of my chnc ?
[13:39:29] <ssi> just sat back down, lemme take a peek
[13:39:58] <ssi> that control looks downright usable :D
[13:40:55] <ssi> super jealous of your accessories
[13:41:01] <ssi> cutoff slide, part chute, AND barfeeder
[13:41:04] <ssi> you're a lucky man
[13:41:11] <cncbasher> yea it runs fine now , had issues with the spindle servo drive , with dry capacitors and it hunting back and forth
[13:41:23] <cncbasher> but runs fine
[13:41:49] <cncbasher> i bought 2 , but the cond was just for spares
[13:42:02] <ssi> did the second have any of the accessories?
[13:42:18] <cncbasher> second one for spares , so i weighed it inn r scrap
[13:43:15] <cncbasher> no the scond one was realy half gutted already
[13:43:44] <ssi> have you done any work with your machine?
[13:44:04] <cncbasher> but changed the bearings and thrust washers in the turret an runs fine
[13:44:15] <cncbasher> yea it runs all day
[13:44:20] <ssi> nice
[13:44:23] <ssi> what are you making with it?
[13:44:29] <cncbasher> set it up and walk away
[13:45:10] <cncbasher> mostly nuts , and studs
[13:45:48] <ssi> i figure one of the first things I'd like to setup on it is making some HDB5 style drill bushings
[13:45:53] <cncbasher> we use the barfeed just about all the time
[13:46:04] <cncbasher> with collets etc
[13:46:07] <ssi> yeah
[13:46:20] <ssi> I put this out to JT as well, but
[13:46:27] <ssi> since your machine is 1/2" turret, and mine is 3/8"
[13:46:32] <ssi> if you come across any 3/8 tooling you can't use
[13:46:38] <ssi> let me know and I'll consider buying it from you
[13:46:58] <cncbasher> yea i'll sure let you know
[13:47:02] <JT-Shop> ssi: I've not seen any 3/8" tooling in any of mine
[13:47:17] <JT-Shop> do you have the link to my CHNC page?
[13:47:24] <ssi> don't think so
[13:47:34] <JT-Shop> http://gnipsel.com/shop/hardinge/hardinge.xhtml
[13:48:14] <JT-Shop> IIRC there are three turrets 1/2" 3/8" and 10mm
[13:48:22] <ssi> oh really
[13:48:26] <JT-Shop> I think the only difference is the height
[13:48:27] <ssi> haven't seen anything about the 10mm ones
[13:48:28] <rob_h> just make the holder blocks, thats all we do :) beats paying hardinge price
[13:48:39] <ssi> rob_h: yeah I'm sure I'll end up making some
[13:48:50] <rob_h> u have the HNC not CHNC
[13:48:51] <JT-Shop> Hi Rob
[13:49:20] <rob_h> turrets do change between machines ok, but center hights are different you will find if rember right
[13:49:27] <ssi> rob_h: yeah HNC
[13:49:29] <rob_h> hi john, just got home :)
[13:49:34] <JT-Shop> me too
[13:49:52] <Tom_itx> me 3, what's for lunch?
[13:49:57] <JT-Shop> just heading down to the beer cave to rack the beer in the fermenter
[13:50:02] <rob_h> currey here
[13:50:23] <JT-Shop> beer and german bologna and cheese for me
[13:50:38] <ssi> JT-Shop: ooh, you've got new ngcgui routines :D
[13:50:48] <JT-Shop> see you guys down there
[13:51:11] <JT-Shop> yea I need to update the web page as I think I have a few more
[13:51:16] <ssi> do it :D
[13:51:27] <ssi> ngcgui is the best thing that happened to me as far as the lathes go
[13:51:41] <cncbasher> ssi: if you look at www.m-machine-metals.co.uk
[13:51:41] <ssi> I'm anxious to check out your profile routine
[13:52:18] <cncbasher> under the engineering tab you can see a bolt cut on it
[13:52:35] <cncbasher> but using a chuck rather than the barfeeder
[13:52:39] <ssi> gotcha
[13:52:49] <ssi> is it too big to use a hex collet and feed through the bore?
[13:53:01] <cncbasher> didnt have any hex collets at the time
[13:53:04] <ssi> gotcha
[13:53:24] <ssi> I have a small production job coming up making a part that's 2" dia, and I'm gonna see if I can get my hands on a step collet to do it
[13:54:06] <cncbasher> theirs a company in the UK that has a lot of 16c and 5c collets
[13:55:37] <cncbasher> www.glostertooling.co.uk , he also advertises on ebay too
[13:57:19] <ssi> is he manufacturing tooling?
[13:57:22] <ssi> or just rebranding chinese stuff
[13:57:30] <ssi> http://www.ebay.co.uk/itm/Gloster-DWLNR2020K06-toolholder-WNMG06-inserts-/370590659968?pt=UK_Home_Garden_PowerTools_SM&hash=item5648ecb580#ht_2807wt_221
[13:57:36] <ssi> that looks like the same stuff that shars carries for instance
[13:58:14] <cncbasher> may well be
[13:58:38] <cncbasher> they all seem to come from the same stable these days
[13:58:56] <ssi> yeah pretty much :)
[13:59:12] <ssi> like I was saying earlier, I wish there were chinese knockoffs of the hardinge tooling
[13:59:25] <ssi> it's nice to be able to buy BXA-sized QCTP toolholders for $9
[13:59:35] <ssi> would be nice if the same sort of market existed for chucker tooling
[13:59:45] <cncbasher> just as easy to make one
[13:59:50] <ssi> no, it's really not
[13:59:54] <ssi> for $9, it's not
[13:59:54] <ssi> :)
[14:01:31] <cncbasher> you can pick them up on ebay
[14:01:33] <ssi> like... if I want to try to copy one of those hardinge CC15 extensions for instance
[14:01:55] <ssi> I http://www.ebay.com/itm/CC-15-3-extension-tool-holder-Hardinge-Omniturn-Haas-/350473120550?pt=BI_Tool_Work_Holding&hash=item5199d36b26#ht_500wt_1378
[14:01:58] <ssi> $150
[14:02:29] <cncbasher> yea ebay gone mad as usual
[14:02:55] <ssi> so if I wanted to make one
[14:03:07] <cncbasher> i only paid £900 for 2 machines
[14:04:04] <cncbasher> so the 3 tubs of tooling was worth more than the machines at that rate
[14:04:14] <ssi> yeah I'm sure
[14:04:29] <ssi> I paid $1000 for my machine, but I had to buy any tooling I wanted from the guy separately :(
[14:04:32] <cncbasher> got 5 turrets too
[14:04:52] <cncbasher> did you get much tooling ?
[14:05:03] <ssi> a fair bit, but not very well rounded
[14:05:10] <ssi> I got zero boring bar holders and zero extension holders
[14:05:12] <ssi> mostly C10s
[14:05:26] <cncbasher> ok
[14:05:29] <ssi> ok so I'm looking at the print of the CC13-16 tools
[14:06:02] <ssi> a CC16 would be made from barstork at least 1.75 x 2 x 5.75"
[14:06:09] <ssi> so 2" barstock, 6" each
[14:06:25] <ssi> I use onlinemetals.com as a "worst case" metal cost estimator
[14:06:41] <ssi> and they list 2" square 1018 as $36/ft
[14:06:47] <ssi> so that's not too terrible I guess
[14:06:53] <ssi> I was looking at 2.5" earlier, and it's like $60/ft
[14:06:54] <ssi> heh
[14:06:54] <cncbasher> yea their expensive
[14:07:08] <ssi> they are expensive, but they're not HUGELY more expensive than my usual metal supplier
[14:07:08] <cncbasher> we sell stock
[14:07:36] <cncbasher> but heavey bar would be expensive on post
[14:07:47] <ssi> yeah especially across the damned ocean ;)
[14:07:58] <rob_h> lol
[14:08:03] <cncbasher> yea just a bit
[14:08:09] <mrsun> on chips like the A3982, can you switch half/full step on the fly ? :)
[14:08:24] <ssi> I may swing by the metal store tonight or tomorrow and buy some stock
[14:08:28] <cncbasher> mrsun : not recomended
[14:08:36] <mrsun> oki, was just a thought =)
[14:08:50] <cncbasher> you would loose steps guaranteed
[14:09:10] <mrsun> ahh true =)
[14:09:57] <jdhnc> the newest g540 seems to change step rate on the fly (consuming the extra pulses)
[14:11:26] <archivist> one does not change half/full step on the fly
[14:11:58] <jdhnc> Morphs to full step at higher speeds to maximize motor torque
[14:13:12] <cncbasher> i'm off for some food chaps bye for now
[14:13:53] <mrsun> jdhnc, yeah that was what i was thinking =)
[14:16:05] <jdhnc> I think that's what I thought you were thinking.
[14:21:12] <thebuc> hello
[14:21:23] <alex4nder> yoh
[14:22:05] <thebuc> anyone here want to help me out with some hal stuff?
[14:23:16] <thebuc> well if anyone does heres a link to my problem http://www.linuxcnc.org/index.php/english/component/kunena/?func=view&catid=24&id=18484
[14:23:30] <thebuc> ill be around
[14:24:16] <mrsun> thebuc, vfd ?
[14:24:20] <mrsun> with pwm signal out ?
[14:24:26] <mrsun> for speed ref
[14:25:09] <mrsun> in my case i had to send the spindle signal to a abs then take that back (M4 reverses the pwm to negative)
[14:25:26] <mrsun> so M4S1000 == M3S-1000
[14:25:27] <cradek> yes I don't understand from your long message what you are trying to do, or what signals your hardware needs
[14:27:04] <mrsun> loadrt abs
[14:27:27] <mrsun> addf abs.0 servo-thread
[14:27:43] <mrsun> net spindle-cmd <= motion.spindle-speed-out => abs.0.in
[14:28:10] <mrsun> hmm, how was it :P
[14:28:17] <jthornton> jdhnc: the 540, 250, 251, and 203v all do micro step morphing since they came out
[14:28:53] <mrsun> net spindle-cmd <= motion.spindle-speed-out => abs.0.in
[14:28:57] <mrsun> net spindle-abs-cmd <= abs.0.out => pwmgen.0.value
[14:29:16] <mrsun> but it requires a direction pin for the vfd also :P
[14:38:48] <mrsun> good way of asking stuff, come and ask then just not be active :P
[15:16:33] <Jymmm> JT-Shop: I got a job for you and your tractor... http://i39.tinypic.com/5fiv6o.jpg
[15:18:46] <archivist> where is that
[15:18:59] <Jymmm> HK I believe
[15:19:12] <Jymmm> or somewhere in china
[15:22:30] <syyl_ws> that can ruin your day
[15:24:06] <JT-Shop> I'm thinking who ever is in the middle is in a tight spot now
[15:26:31] <thebuc> hmm sorry about that let me check out the stuff u sent me. i was at lunch :\
[15:44:50] <mrsun> thebuc, ahh =)
[15:45:18] <mrsun> thebuc, that worked for me, ive got a CW and a CCW signal for the spindle and 0 - 100% duty on one parport pin pwm that is
[15:45:34] <mrsun> if its not absoluted the M4 becomes negative duty cycle
[15:45:41] <mrsun> or something like that =)
[15:45:50] <mrsun> pulling the pwm to 0
[15:45:55] <mrsun> and voila, spindle stops
[15:46:12] <mrsun> on M4
[15:46:33] <thebuc> hmm
[15:46:45] <thebuc> i tried putting your stuff in directly but i think i need to tweak it some if its going to work
[15:47:09] <thebuc> i was already using hte motion.spindle.speed out pin and it gave me an error
[15:47:18] <thebuc> :(
[15:48:19] <thebuc> hey actually i think u are right
[15:48:25] <thebuc> i just checked my hal config
[15:48:32] <thebuc> it said a negative value
[15:48:35] <thebuc> with m4 on
[15:48:45] <mrsun> thebuc, its cause its already in the "yourmill.hal" file
[15:48:47] <thebuc> so im going to try to figure out what yo usaid
[15:49:19] <mrsun> try editing in that in the actual hal file not custom.hal ... tho it will disapear each time you use the config wizard
[15:49:26] <mrsun> loadrt abs
[15:49:32] <mrsun> addf abs.0 servo-thread
[15:49:37] <mrsun> remember those also =)
[15:51:30] <thebuc> yeah i usually do in the main hal file
[15:51:53] <thebuc> going to tyr what you say again
[15:59:48] <thebuc> i got an error saying spindle-abs-cmd pin doesnt exsist
[15:59:52] <thebuc> hmm
[16:03:14] <thebuc> oh i guess because that is a signal and i haven't made it yet?
[16:03:22] <Jymmm> I'm trying to design a lamp shade of various sizes. I'm clueless on the math I need to draw this out correctly. I think it has to do with cones, but I'm not sure. any suggestions?
[16:03:42] <ssi> a lampshade is a frustrum of a cone
[16:03:51] <ssi> frustum excuse me
[16:03:52] <Jymmm> a frusting?
[16:03:58] <Jymmm> say what?
[16:04:02] <ssi> http://en.wikipedia.org/wiki/Frustum
[16:04:41] <ssi> http://www.mathwords.com/f/frustum.htm
[16:04:54] <Jymmm> I dont speak greek or latin tyvm
[16:05:11] <ssi> I'm just speaking math :D
[16:05:22] <Jymmm> and the difference is?
[16:05:35] <ssi> http://mathworld.wolfram.com/ConicalFrustum.html
[16:05:37] <ssi> I dunno
[16:05:39] <ssi> you asked, trying to help
[16:05:44] <ssi> I'll go back to what I was doing I guess
[16:05:54] <Jymmm> I also said I was clueless too =)
[16:06:11] <Jymmm> I kow it looks like a happy face when flat.
[16:06:25] <ssi> does it?
[16:06:29] <Jymmm> yeah.
[16:06:33] <ssi> planview would be a pair of concentric circles
[16:06:39] <ssi> oh you mean unrolled
[16:06:42] <ssi> yeah I guess so
[16:06:53] <Jymmm> Yes, that is what flat means =)
[16:07:10] <Jymmm> at least to me
[16:07:11] <ssi> not necessarily
[16:07:17] <ssi> that's why words like "frustum" exist
[16:07:20] <ssi> because words mean things
[16:07:28] <Jymmm> words get in the way.
[16:07:38] <Jymmm> as do maths greeks and latins ;)
[16:07:47] <ssi> flat can mean unrolled, or any of the 2 dimensional projections of a 3 dimensional object
[16:07:53] <ssi> or without carbonation
[16:07:57] <ssi> or below pitch
[16:08:01] <thebuc> lmao
[16:08:15] <Jymmm> It's a lampshade, flat means flat =)
[16:08:35] <Jymmm> unless alcohol is involed, then anythng is possible
[16:08:50] <ssi> sorry I didn't realize we were using lampshade physics jargon
[16:09:03] * ssi consults his Institute of Lampshade Studies Handbook
[16:09:25] <Jymmm> See, that's the problem, if you need to consult a book, it's too complicated =)
[16:09:40] <Jymmm> I need a dumbass version =)
[16:10:14] <ssi> here's the dumbass version
[16:10:14] <ssi> http://www.ehow.com/how_5082178_make-lampshade-pattern.html
[16:10:37] <ssi> the book version would be something involving the circumference of the major and minor diameters
[16:10:40] <mrsun> thebuc, dont know =) to old linuxcnc? :)
[16:11:06] <ssi> http://mathcentral.uregina.ca/QQ/database/QQ.09.02/ellsie1.html
[16:11:10] <ssi> there's the slightly less dumbass version
[16:11:53] <ssi> now... I need the dumbass version as to whether hooking up this HNC is going to make the control explode
[16:12:03] <ssi> I have two methods of powering it: a 3hp VFD or a 1hp static converter
[16:13:48] <Jymmm> ssi: Where did the '2' come from in this from the link your provided... 2 * pi * 12 = 75.4 inches.
[16:14:09] <thebuc> yeah must be too old of a version or somethign
[16:14:13] <ssi> circumference is 2piR
[16:14:25] <ssi> R is the slant height to a point, which is 12"
[16:14:57] <ssi> actually I don't think that's quite right
[16:15:14] <ssi> oh nm
[16:15:23] <ssi> the circumference of the circle that becomes the bottom of the lampshade
[16:15:25] <ssi> is also the arc length
[16:15:34] <mrsun> thebuc, from what i understand they added it in the later versions, but it is int he later stables =)
[16:16:10] <ssi> so in his case, it's a 24" diameter shade at the bottom, so R = 12, 2piR is the circumference of the bottom of the shade, and that's the same as the arc length of the flat pattern
[16:20:56] <mrsun> thebuc, anyways, good luck thats the only solution i have as it worked for me =) time to sleep
[16:31:03] <DJ9DJ> gn8
[17:08:57] <joe9> does linuxcnc or emc2 work with ubuntu 11.10?
[17:09:00] <joe9> has anyone tried it?
[17:09:29] <joe9> there are some old packages that are proving to be a bother with 10.04.
[17:09:35] <Mjolinor> does anything work with 11.10??
[17:10:04] <Mjolinor> sorry, sore point with me is 11.10, unity sucks
[17:10:15] <joe9> oh, ok.
[17:11:20] <joe9> unity would have the latest packages, and it would be easy to get my system to that release, hence, was wondering about it.
[17:11:40] <Mjolinor> so you ahvent used it?
[17:11:44] <Mjolinor> 11.10 I mean
[17:12:05] <Mjolinor> if you are a seasoned Ubuntu user then you will be shocked by it
[17:12:07] <joe9> no, I have not used it.
[17:12:17] <joe9> oh, that bad. ok, will stick with 10.04 then.
[17:12:23] <Mjolinor> I found it awful to use, couldnt find anythign or do anything
[17:12:29] <Mjolinor> :)
[17:13:00] <Mjolinor> i have it n a couple of computers not wanting to be defeatist adn stuck in the mud but I cant make friends with it at all
[17:13:22] <Mjolinor> I am afraid that once 10.04 starts not working I am off to Bodhi or Mint
[17:14:03] <joe9> what about linuxcnc? will it work on Bodhi/mint?
[17:14:03] <alex4nder> the only thing that's a pain in the ass is getting a working RTAI kernel.
[17:14:23] <joe9> alex4nder: with unity, I mean?
[17:14:24] <Mjolinor> I think it should work with both Bodhi adn Mint but I dont know
[17:14:49] <joe9> i just upgraded from debian to lucid for linuxcnc.
[17:14:52] <alex4nder> joe9: no I mean getting emc2/linuxcnc working
[17:15:02] <joe9> oh, ok.
[17:15:36] <alex4nder> the rest of it is easy
[17:19:11] <Mjolinor> I stuck my new (second hand, ebay) siemens inverter on my orac tonight
[17:19:46] <Mjolinor> it was a shock how smooth it was compared to the old inverter, I didn't expect it to be any different but it runs slower and doess not heat the motor at all
[17:20:03] <Mjolinor> I didnt think there would be a lot to choose between different makes but it seems there is
[17:21:33] * JT-Shop might cook some bubbles and squeak for dinner
[17:22:22] * Mjolinor thinks that is an odd vision, soemone cooking bubbles while squeaking
[17:26:57] * flyback eats his dinner before tearing into his package from sparkfun.com like a kid at xmas
[17:36:25] <JT-Shop> I learned it from rob_h
[17:55:50] <JT-Shop> seems the boat Andy is on has a problem and has dropped out of the pack and is in stealth mode for some reason
[17:56:34] <JT-Shop> might be an uplink problem
[17:57:15] <ssi> got my new bandsaw running... it's awesome :D
[18:00:53] <ssi> http://www.youtube.com/watch?v=aTyh47ft3u4&feature=youtube_gdata_player
[18:01:46] <JT-Shop> cool, I have one similar to that
[18:02:03] <Tom_itx> JT-Shop, call him up on his sat phone and find out what's up :)
[18:02:07] <archivist> JT-Shop, playing their joker http://www.clipperroundtheworld.com/index.php/race-news/
[18:02:08] <JT-Shop> tough time to keep the roller guides aligned
[18:02:27] <ssi> it's worlds better than my old 4x6 harbor freight POS
[18:02:28] <archivist> hiding from the others, were in second place
[18:03:01] <JT-Shop> cool
[18:03:55] <ssi> JT-Shop: so I was reading about the problems you and others had trying to run the chnc on a vfd, and it seemed like it was the noise suppressors on the spindle motor's power leads... is that accurate?
[18:04:25] <JT-Shop> a little black thing on each contactor would let the magic smoke out
[18:05:08] <ssi> I wonder if it's necessary magic smoke :)
[18:05:28] <JT-Shop> probably not
[18:06:00] <JT-Shop> off to Hydes for some cat fish... no bubbles and squeak it seams
[18:06:16] <ssi> what on earth is bubbles and squeak
[18:06:27] <ssi> all I can think of is beer and cheese curds :P
[18:06:44] <archivist> bubble singular
[18:07:08] <Mjolinor> its bubble adn squeak
[18:07:18] <ssi> you brits name your food really screwy
[18:08:13] <Mjolinor> it's so we can have secret conversations about food
[18:08:43] <archivist> pork scratchings
[18:09:07] <Mjolinor> tatty oggie
[18:09:35] <archivist> spotted dick
[18:09:54] <Mjolinor> sympathy for you
[18:10:04] <Mjolinor> oh, right, the pudding you mean
[18:10:41] <archivist> toad in the hole
[18:12:00] <Mjolinor> Anyway what about the swedish
[18:12:06] <Mjolinor> they have really odd names for food
[18:12:16] <Mjolinor> and they eat really odd food too
[18:12:39] <Mjolinor> surstromming being a good example, stupid name and how the hell anyone eats it will never know
[18:13:20] <ssi> everything the swedish say sounds weird
[18:13:26] <Mjolinor> http://www.youtube.com/watch?v=hOcSU3gPTYI
[18:13:34] <Mjolinor> that gives you soem idea of how it smells
[18:13:57] <archivist> http://www.youtube.com/watch?v=IfeyUGZt8nk
[18:14:46] <ssi> lord why
[18:16:23] <ssi> archivist: lolololol
[18:21:54] * flyback bbl
[21:52:12] <oxiredo_ro> hello
[21:52:20] <oxiredo_ro> hello
[21:53:16] <oxiredo_ro> I want to start making a CNC machine ( i have no experience with this). where can i start this ?
[21:54:23] <jdhnc> credit cards are a good way to start.
[21:54:46] <oxiredo_ro> hmm...ok
[21:55:55] <jdhnc> what do you want to make with it? What materials? How much room?
[21:58:05] <oxiredo_ro> I want to start with a small one/room.
[21:58:25] <jdhnc> mill? router? lathe? 3d-printer?
[21:59:05] <oxiredo_ro> I sow on youtube a 3d printer, so, a 3d printer
[21:59:16] <oxiredo_ro> i dont know what are the other
[22:01:12] <oxiredo_ro> I realy dont know anything about CNC
[22:03:18] <Tom_itx> want a kit or scratch build one?
[22:03:40] <Tom_itx> i think mendlemax is supposed to be a good one
[22:03:53] <Tom_itx> talk to maxbots in #seattlerobotics if you want
[22:08:01] <oxiredo_ro> tnx fro help, I need to study this more. and also the "credit card issue" :)
[22:08:50] <djdelorie> makerbot and printrbot are other kits you could investigate
[22:09:09] <oxiredo_ro> k, tnx
[22:10:05] <Tom_itx> i'm not into the reprap stuff, i just know maxbots
[22:10:17] <Tom_itx> and that he was working on a kit
[22:11:06] <oxiredo_ro> and how do I integrate those machne with a PC
[22:11:20] <oxiredo_ro> can i make it via microcpntrollers..?
[22:11:31] <oxiredo_ro> or dedicated cnc controllers ?
[22:12:14] <Tom_itx> some of them use dedicated controllers
[22:12:28] <Tom_itx> like i said, i don't know alot about em
[22:12:36] <Tom_itx> i'd suggest you visit with him
[22:12:53] <Tom_itx> or join #reprap
[22:19:42] <oxiredo_ro> good/night all ! :)
[22:21:56] <theos> night!
[23:59:28] <ssi> what a pain in the ass
