[00:17:43] <MacGalempsy> evening. merry christmas
[01:48:23] <Mr_Mayhem> Merry Christmas, ho-ho-ho. Where's the video of Santa running linuxcnc?
[01:50:42] <Mr_Mayhem> His elves in the workshop running lathes and mills... Or something like that. The Penguin would feel at home too! Common guys, this is a no brainer!
[01:52:44] <WalterN> everyone is busy partying
[01:54:24] <Mr_Mayhem> ha
[01:56:07] <Mr_Mayhem> http://gizmodo.com/5422694/santas-real-workshop-amazons-gargantuan-distro-centers
[01:58:57] <WalterN> yeah
[01:59:03] <WalterN> looks basically like costco
[01:59:25] <WalterN> only more floor space :P
[02:00:10] <Mr_Mayhem> Yeah, lol. That is some crazy logistics.
[02:34:32] <Cylly> mornin'
[02:41:49] <Deejay> moin
[02:42:19] <Deejay> merry xmas!
[02:47:38] <Deejay> re
[03:32:38] <JeAl> hi
[03:33:08] <JeAl> merry christmas
[06:35:04] <jthornton> merry xmas
[08:08:32] <jthornton> on a rack drive you just need the pitch of the rack and how many teeth are on the gear to know how far it travels for one turn of the gear?
[08:08:59] <archivist> yes
[09:30:42] <Tom_itx> JT-Shop, it's just 2 gears with one unrolled
[10:11:01] <JT-Shop> I'd like to see the machine that unrolls it
[10:12:03] <archivist> the rack makes the rolled up version
[10:13:02] <archivist> gear generation is a strange concept
[10:14:02] <Tom_itx> it's like a bit razor :D
[10:14:07] <Tom_itx> big*
[10:14:43] <Tom_itx> similar to making plywood
[10:15:20] <archivist> the maths for bevel generation and insanity http://www.archivist.info/gear/designbevel.php
[10:18:42] <Tom_itx> i like your version number
[10:20:50] <archivist> E&OE says it all :)
[10:21:21] <archivist> until I produce a clean gear at the right angle
[10:30:17] <Tom_itx> then when you do, you can write a template for my cad cam :)
[11:03:54] <archivist> I think it may be more than a "template"
[11:06:58] <archivist> Tom_itx, one needs to gear A-B and have them at an angle from each other http://www.collection.archivist.info/archive/DJCPD/PD/2013/2013_08_11_bevel/IMG_1632.JPG
[11:34:50] <Tom_itx> archivist, i know it's not that simple, just being silly
[11:38:12] <archivist> I get silly requests, used to it, like the other week, make n 1 off gears at 1000 off production prices
[11:39:07] <Tom_itx> heh i'm sure
[11:40:44] <archivist> the cutter alone for one size gear was £68+vat and carriage and was offered £5 a gear ..... rather impossible
[11:50:41] <pcw_home> you lose money on each one but make it up on the volume :-)
[11:51:25] <archivist> one off is a rather poor volume :)
[12:11:14] <eric_unterhausen> is 40% fill ok for EMT conduit?
[12:14:36] <jthornton> I've seen it 105% full
[12:16:39] <CaptHindsight> eric_unterhausen: depends on what code you want to conform to
[12:19:04] <eric_unterhausen> you can't be 105% full, or does that involve wire ties on the outside?
[12:19:41] <eric_unterhausen> I'd like to follow the residential code
[12:20:15] <CaptHindsight> eric_unterhausen: unless you're on a town that has lots of code variances just check the current NEC
[12:20:17] <jthornton> codes vary from state to state unless you follow the national electrical code
[12:20:25] <jthornton> we have no codes here
[12:20:47] <eric_unterhausen> I think we are following the NEC from 1950 or so
[12:21:16] <eric_unterhausen> I tried to get Cletus to put gravel under my deck, they only did about 1/4 of it, inspectors didn't care
[12:21:26] <CaptHindsight> how many conductors? what insulation and what size conduit are you using?
[12:21:54] <eric_unterhausen> I have 6 14AWC, 3 12AWG and 4 10AWG
[12:22:03] <eric_unterhausen> right at 40% the way I calculate
[12:22:20] <CaptHindsight> how many are current conducting?
[12:22:45] <CaptHindsight> or is this just for signals?
[12:22:47] <eric_unterhausen> I have 4 grounds
[12:23:21] <eric_unterhausen> and 2 neutrals on 220 single phase. does that make a difference?
[12:23:24] <CaptHindsight> nevermind, 10ga signal would be silly
[12:24:05] <CaptHindsight> yes, fill is based on physical volume, wire insulation and current carrying conductors
[12:24:33] <PetefromTn> Morning Everyone Merry Christmas.
[12:25:15] <CaptHindsight> >3 current carrying conductors in one conduit requires derating of the breakers
[12:27:31] <IchGuckLive> hi all B)
[12:27:45] <eric_unterhausen> how much derating?, I'm at 25%
[12:28:13] <CaptHindsight> I dropped my license ~29 years ago, but it's something like 25 or 30%
[12:28:16] <eric_unterhausen> actually 30%
[12:28:53] <CaptHindsight> is any of it 3 phase wye?
[12:30:23] <CaptHindsight> wye counts the neutral as a conductor if there are any non-linear loads that cause harmonics such as switching power supplies
[12:31:27] <CaptHindsight> so depending on how long the runs are it's sometimes cheaper to run more conduit and less copper
[12:31:28] <eric_unterhausen> no, it's all single phase
[12:32:58] <CaptHindsight> with single phase 120/240 the lines count as a conductor each and the neutrals don't count
[12:33:22] <eric_unterhausen> looks like I'm ok, although I don't have a NEC handy
[12:33:59] <CaptHindsight> the problem you can still get into is if you don't share/balance the neutrals
[12:37:58] <CaptHindsight> the two 120V lines sharing a neutral should be from opposite lines, so 240V when measured across them
[12:39:37] <CaptHindsight> if you have two 120V lines (even though from separate circuits/breakers) sharing a neutral the neutral can have 2X the current (the sum of both circuits) vs just the imbalance
[12:41:23] <archivist> just think about that :)
[12:41:25] <CaptHindsight> so even though the lines have current protection say at 20A the neutral will have 40A on it at full load vs 0A if balanced
[12:41:36] <IchGuckLive> better to go 400V
[12:42:20] <IchGuckLive> oh the US got only 110 in the Net
[12:42:49] <archivist> US has a broken mains system
[12:43:13] <IchGuckLive> it still has powerlines on top of the earth
[12:43:26] <IchGuckLive> avery snow storm breaks the ingeners neck
[12:43:36] <CaptHindsight> the US used to be mostly 120?240 delta
[12:43:52] <CaptHindsight> they started changing over in the 80's to 120?208 wye
[12:45:07] <CaptHindsight> even the high voltage that ran down the poles within cities were delta
[12:46:45] <CaptHindsight> so the rest of the world learned from our mistakes, NTSC, delta, slavery etc
[12:46:56] <archivist> EU has no two phase like the US as far as I know
[12:47:43] <IchGuckLive> i researched ! 180.000 killed by diabetes 30.000by Weppens,500 on Power in 2012
[12:48:17] <CaptHindsight> we need to wage a war against diabetes!!
[12:48:35] <CaptHindsight> and super bacteria
[12:48:49] <IchGuckLive> 180Grams of shugar in one bottel of coke thats the mainstream killer
[12:49:17] <IchGuckLive> good cheep and fat food for the most
[12:49:33] <IchGuckLive> you need to earn lots of money to stay healthy
[12:49:40] <CaptHindsight> but where's the fun in that?
[12:49:51] <IchGuckLive> and a Bigmac a day makes you happy
[12:50:12] <CaptHindsight> do you really want a world full of healthy and well educated people running around?
[12:50:19] <IchGuckLive> What is the averige price of a standart cheesburger
[12:50:33] <CaptHindsight> just think of the problems that would cause
[12:51:45] <CaptHindsight> http://www.nytimes.com/2013/09/17/health/cdc-report-finds-23000-deaths-a-year-from-antibiotic-resistant-infections.html?_r=0
[12:51:48] <IchGuckLive> no its good that way BUT get the 77USD/year minimum Health fee and 150.000 more jobs in healthcare From obama
[12:52:35] <IchGuckLive> CaptHindsight: agree i got one myself this year not a good way tolive
[12:53:04] <CaptHindsight> but the "real" threat is those terrorists "so bend over and show me your papers"
[12:54:44] <eric_unterhausen> I am not sure having 120 v single phase is a problem
[12:54:52] <eric_unterhausen> wish it was easier to get 3 phase though
[12:55:29] <IchGuckLive> eric_unterhausen: isent there 3Pases on all howses in the USA as standard in
[12:55:44] <eric_unterhausen> no, I"m not sure where it ends
[12:55:59] <eric_unterhausen> my understanding is that the tranformers at the street are single phase
[12:56:16] <IchGuckLive> yes but on 2lines
[12:56:21] <IchGuckLive> 3lines
[12:56:41] <IchGuckLive> so you got 3 120V to the House 1 N and one Gnd
[12:56:43] <eric_unterhausen> still single phase in/single phase out
[12:57:08] <IchGuckLive> if you use only the 3 lines L1 L2 L3 you got 240
[12:57:16] <IchGuckLive> within them
[12:57:19] <eric_unterhausen> to get 3 phase costs quite a bit unless you are in an industrial area
[12:57:19] <CaptHindsight> for residential it's 3 wires, 120/208, 2 poles and the center neutral
[12:57:26] <IchGuckLive> no N Blue requiered
[12:58:12] <IchGuckLive> o i need to get of this as i never lived in the states only 6month as i wars young and that is quite a time
[12:58:33] <eric_unterhausen> looks like I am supposed to derate 20% for up to 6 conductors
[12:58:44] <IchGuckLive> but your oven in the kitchen shoudt got the 3 lines
[12:59:08] <eric_unterhausen> code requires 3 lines plus ground for oven/stove
[12:59:17] <eric_unterhausen> unless the locale is behind the times
[12:59:29] <CaptHindsight> for older homes you might still have 120/240, 3 wires, 120..neutral..120 from a delta
[13:00:43] <CaptHindsight> eric_unterhausen: yeah. continuous maximum load should not be more than 80%
[13:01:14] <CaptHindsight> so no 19A on a 20A breaker
[13:01:55] <eric_unterhausen> my loads are much less than the rating of the circuit
[13:02:13] <CaptHindsight> so a 19A load, say a heater would need to be on a 30A circuit
[13:02:51] <eric_unterhausen> they are all rated for startup currents
[13:03:44] <CaptHindsight> motor ratings are another story to determine what wire size and breaker is required
[13:04:06] <IchGuckLive> ok im off BYE have a good chrismas eve
[13:04:11] <eric_unterhausen> yeah, and the companies rating them are usually not that great at it
[13:06:35] <eric_unterhausen> I have a bad feeling that I'm going to be changing a transaxle in my car in the bitter cold
[13:07:31] <CaptHindsight> I recall my clutches and transmissions only needing replacement when the temp was under 20F
[13:07:39] <eric_unterhausen> ya, same here
[13:07:52] <eric_unterhausen> it's a feature of winter
[13:08:12] <eric_unterhausen> it started acting up in June, but I ignored it
[13:09:01] <CaptHindsight> I still remember waiting to change my trans when it was 13F since it was a warm up over -10
[13:09:34] <eric_unterhausen> I got sick of one car breaking down when it was cold and just gave it away
[13:09:39] <eric_unterhausen> hopefully the guy got it working
[13:09:53] <eric_unterhausen> actually, I don't think much was wrong with it, just time to move on
[13:10:05] <CaptHindsight> I know the feeling
[13:12:04] <CaptHindsight> now I drive the most reliable vehicles and still do preventative rebuilds
[13:12:38] <eric_unterhausen> dunno if you can get parts for this transmission
[13:12:48] <CaptHindsight> what is it?
[13:12:50] <eric_unterhausen> the used ones are $700, dealer wants 4200
[13:12:53] <eric_unterhausen> Prius
[13:12:59] <CaptHindsight> what year?
[13:13:04] <eric_unterhausen> 2006
[13:14:01] <Tom_itx> salvage
[13:14:25] <eric_unterhausen> ya, the transmissions never go bad, or so the Prius nuts tell me
[13:14:27] <Tom_itx> i got 2 for $10 of a part costing $200 there
[13:14:28] <CaptHindsight> $200 from a boneyard around here
[13:14:31] <Tom_itx> works great too
[13:14:54] <eric_unterhausen> Capt, aren't you near Philly?
[13:15:16] <CaptHindsight> I'd buy a low mileage used one for $200 and rebuild it myself
[13:15:25] <CaptHindsight> Windy City
[13:15:39] <Tom_itx> anywhere in Ks? :D
[13:15:42] <eric_unterhausen> yeah, $200 in winter, $1000 in summer :)
[13:15:48] <CaptHindsight> ~$500 for everything
[13:16:24] <CaptHindsight> http://car-part.com/cgi-bin/search.cgi?userSearch=int&userPID=1000&userLocation=chicago&userIMS=&userInterchange=C%3EDF%3F&userSide=&userDate=2006&userDate2=2006&dbModel=
[13:16:31] <CaptHindsight> yikes, sorry
[13:17:10] <eric_unterhausen> I wonder why searching in Pennsylvania gets so much higher price
[13:17:16] <eric_unterhausen> wonder if those guys would ship
[13:17:20] <CaptHindsight> it happens
[13:17:35] <CaptHindsight> yeah, ~$100 on a pallet
[13:18:27] <CaptHindsight> oh wait $80 in NJ
[13:18:42] <eric_unterhausen> rockford guys can't figure out how to read mileage :)
[13:19:03] <eric_unterhausen> I used to go there occasionally
[13:19:09] <CaptHindsight> http://tinyurl.com/o3aoq3q
[13:19:38] <eric_unterhausen> stolen car :)
[13:20:00] <CaptHindsight> you tell them what you need and they "find" it by the next day
[13:20:12] <eric_unterhausen> I had some bone grafts put in my jaw recently, I made sure they didn't come from New Jersey
[13:20:54] <CaptHindsight> Leesville Auto Wreckers, Inc. - PRP-NE-ELITE USA-NJ(Rahway) Request_Quote 1-888-879-5573 $210
[13:21:17] <eric_unterhausen> is "insurance quote" code for "don't care if the price is higher"?
[13:21:41] <CaptHindsight> nah, that will be the price over the phone
[13:21:57] <CaptHindsight> some shops just need written quotes
[13:22:20] <CaptHindsight> All Foreign Auto Parts - ARAPro USA-PA(Pittsburgh) $200
[13:22:39] <CaptHindsight> lowest prices, not in Jersey
[13:23:12] <CaptHindsight> do you have to pull the engine to swap the trans?
[13:23:17] <eric_unterhausen> I'd be happy spending less than $700
[13:26:31] <eric_unterhausen> no, you can drop the transmission by itself
[13:26:39] <eric_unterhausen> there is a crossmember you have to take out
[13:26:51] <eric_unterhausen> weighs about 300 pounds
[13:26:55] <CaptHindsight> ebay 380287202694 entire engine and trans for $1200 only 22K miles
[13:27:25] <eric_unterhausen> I think everything stayed the same up until 2009
[13:30:22] <eric_unterhausen> funny to see a salvage yard using the car-part.com search engine on their own inventory
[13:32:35] <CaptHindsight> some bone yards just have a trailer and a field of mud
[13:33:10] <CaptHindsight> they get a PC and sat internet and get on the grid
[13:36:28] <CaptHindsight> http://lh4.ggpht.com/_LqX5iouzQo4/TQ1d4Yn1tEI/AAAAAAAAC8I/0LBhXfIkgyA/s640/P1010307.JPG my project this afternoon
[14:04:39] <eric_u_cnc> I'm glad I didn't post anything about Seb's new kernel working for me
[14:05:14] <eric_u_cnc> I am getting 74 uS just using the internet
[14:05:41] <eric_u_cnc> this machine runs about 10uS using liveCD
[14:06:28] <eric_u_cnc> actually does that running from live cd, which is probably worst case
[14:10:30] <CaptHindsight> RTAI kernel? what cpu and chipset?
[14:10:51] <eric_u_cnc> actually, I did post before doing much stress testing
[14:11:28] <eric_u_cnc> it's 3.4.55-rtai-2 #1 SMP PREEMPT
[14:12:30] <eric_u_cnc> amd cpu
[14:13:03] <eric_u_cnc> cpu family 15, model 107 whatever that means, dual core
[14:13:37] <CaptHindsight> same BIOS setting Live-CD vs 3.4.55-rtai-2 #1 SMP PREEMPT?
[14:13:47] <eric_u_cnc> yes
[14:14:03] <eric_u_cnc> could be video
[14:14:18] <CaptHindsight> athlon 64 x2
[14:14:28] <CaptHindsight> K10 family
[14:14:58] <CaptHindsight> had a few of those well under 10us
[14:15:16] <skunkworks> what is an inexpensive breakout board with a charge pump?
[14:16:27] <eric_u_cnc> how do you tell what video driver is running?
[14:18:33] <CaptHindsight> lshw -c video
[14:19:19] <eric_u_cnc> I had a usb flash drive in, doesn't that screw things up sometimes?
[14:20:12] <CaptHindsight> check with memleak in the dev channel when gets back this weekend
[14:20:22] <CaptHindsight> he worked on the RTAI stuff
[14:23:03] <eric_u_cnc> haha, opening tabs on firefox ran it up to 1370 uS :)
[14:24:17] <eric_u_cnc> lshw says it's a radeon, doesn't list a driver
[14:24:21] * JT-Shop is running out of space to stack fire wood... never had that problem before in the last 60 years
[14:25:08] <eric_u_cnc> people in New Jersey are just getting over that problem from Sandy
[14:25:31] <eric_u_cnc> there was wood everywhere for a while
[14:34:35] <eric_u_cnc> too bad it's not easier to troubleshoot latency
[14:34:47] <eric_u_cnc> is "radeon" an open source driver?
[14:38:15] <skunkworks> no
[14:39:08] <skunkworks> uh - maybe it is
[14:39:21] * skunkworks is a lot of help today
[14:48:05] <eric_u_cnc> bios changes didn't help
[14:52:49] <eric_unterhausen> radeon is open source
[14:54:22] <eric_unterhausen> that's no good, I guess I'll have to try the vesa driver
[14:54:25] <eric_unterhausen> or smi
[15:00:24] <eric_unterhausen> maybe I'll install the xenomai kernel and UB and see how that does
[15:21:10] <eric_unterhausen> after all that navel-gazing about conduit, I decided it wasn't a good idea
[15:22:17] <eric_unterhausen> and putting up more conduit is made more difficult by the placement of the radon mitigation system piping
[15:22:49] <skunkworks> eric_unterhausen: you could try a few things.. disable lagecy usb, and the sound card in the bios..
[15:23:06] <skunkworks> Try adding idle=poll to the kernel line..
[15:25:35] <eric_unterhausen> ok, I'll go try that
[15:28:35] <eric_unterhausen> have I mentioned today that I hate grub2?
[15:28:57] <skunkworks> heh - I have to look up every time on how to and what to edit.
[15:29:15] <eric_unterhausen> I think I will suggest to the devs that they call it 'lilo'
[15:30:30] <eric_unterhausen> bait and switch, they killed lilo and then they made grub just like it
[15:37:41] <eric_unterhausen> first link i found on ubuntu forums says to change the default command line
[15:37:55] <eric_unterhausen> nice to have bad info come up first on google
[15:43:21] <eric_unterhausen> anyone know the name of latency test?
[15:44:07] <pcw_home> latency-test
[15:44:20] <eric_unterhausen> thanks, that's the one iteration I didn't try
[15:44:50] <pcw_home> there's also latencyhistogram
[15:47:33] <eric_unterhausen> does it seem likely to anyone that running firefox over X is better for latency?
[15:47:41] <eric_unterhausen> I guess I should go downstairs and try again
[15:51:44] <eric_unterhausen> must be the video drivers
[15:52:17] <eric_unterhausen> I open tabs on firefox over X and no latency spike, on the computer it gives latencies on the order of a millisecond
[16:10:59] <eric_unterhausen> I guess I need to install the non-free ethernet firmware
[16:25:15] <eric_unterhausen> when I try to use dpkg to install firmware, it complains that linux-firmware already has a file of same name
[16:38:11] <eric_unterhausen> well, it didn't break anything :)
[16:47:40] <eric_unterhausen> well, dmesg doesn't have any complaints, we'll see if it fixes the network
[17:09:47] <eric_u_cnc> disabling sound card and idle=poll didn't do it
[17:10:01] <eric_u_cnc> guess I need to look up how to install vesa drivers
[17:19:40] <Deejay> gn8
[17:26:32] <pcw_home> eric_u_cnc: what motherboard?
[17:28:32] <eric_u_cnc> asrock something or other
[17:30:00] <eric_u_cnc> retired from my son's desktop because he needed a supercomputer to run his games
[17:30:33] <eric_u_cnc> aod790gx
[17:59:36] <eric_u_cnc> a game we like to call, "editing fstab when you don't exactly know what you are doing"
[18:40:09] <CaptHindsight> eric_u_cnc: we have an Asrock board that just wont cooperate here, 780 chipset and broken BIOS
[18:40:42] <CaptHindsight> was a challenge just to get it to run some form of Linux
[19:20:15] <eric_u_cnc> this board has always cooperated
[19:20:31] <eric_u_cnc> I think they put random bioses on just to mess with people
[19:21:09] <eric_u_cnc> although ubuntu 10 would randomly lock it up
[19:21:20] <eric_u_cnc> 12.04 has been really stable
[19:52:04] <nsp> how many limit switches are required for a good router function
[19:52:17] <nsp> my 3d printer only uses 3 but i see some router designs use 5
[19:52:51] <kengu> nsp: 3d printers usually use the switches for homing and not limiting for real
[19:53:22] <kengu> in router it might be good to have both limits (min/max) for each axis
[19:53:41] <kengu> depending on the size of router
[19:54:22] <kengu> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Homing_And_Limit_Switch
[19:54:34] <nsp> next question- i have one of those tb 6560 boards and they can only handle 4 limit switches
[19:55:52] <nsp> oh i see
[19:55:53] <nsp> http://www.hobbycncaustralia.com.au/Instructions/iI19wirelimit.htm
[19:55:57] <nsp> looks like this will work
[19:57:00] <kengu> also 1.6.5 in the wiki page
[20:15:05] <nsp> where can you buy nema 23 with built in linear drives
[20:21:36] <CaptHindsight> a linear positioner with nema23 motors?
[20:23:34] <CaptHindsight> nsp: something like this? http://www.powellsurplus.com/picts/Parker402006_a.jpg
[20:24:33] <nsp> no, something that is just a nema 23 with a leadscrew built in. I dont even know how much better this is then jsut attaching a normal nema motor to a lead screw via a coupler
[20:24:54] <CaptHindsight> oh a nema23 leadscrew motor
[20:25:37] <CaptHindsight> http://image.made-in-china.com/43f34j00mvEaMzRWOOrQ/NEMA-23-Lead-Screw-Stepper-Motor-23HS-8HB-.jpg
[20:25:46] <CaptHindsight> like this ^^^ ?
[20:28:43] <nsp> it looks like that one has a coupler but yeah
[20:30:21] <nsp> do they make M11 thread size?
[20:30:46] <CaptHindsight> lots of suppliers
[20:32:17] <nsp> im trying to decipher how to make this router and it says they use an antibacklash nut called a TR11 does that mean it accepts M11 threaded rod as the linear drive?
[20:55:15] <CaptHindsight> nsp: an antibacklash nut might be something like this http://buildyourcnc.com/CNCMachineMechanicalParts.aspx
[20:55:55] <CaptHindsight> nsp: where are these router instructions posted?
[20:56:37] <nsp> yep those are them- looking for them on mcmaster now
[20:57:32] <CaptHindsight> others use a delrin nut with a slight interference fit
[20:57:43] <CaptHindsight> but the interference wears out over time
[20:57:47] <nsp> http://www.instructables.com/id/The-AnniRouter-v02body-only/
[20:58:50] <nsp> http://www.mcmaster.com/#general-purpose-acme-rods/=pyvx7v
[20:58:56] <nsp> i want to use these threaded rods
[21:00:17] <CaptHindsight> just look for matching acme screws and nuts, diameter and pitch
[21:09:47] <nsp> yeah i got the acme screw and looking for the antibacklash now
[21:10:46] <nsp> problem is in the CAD it says 11mm diam on the leadscrew motor but all that is available is M12 or M8
[21:13:51] <R2E4> Hi all
[21:14:22] <R2E4> Has there been a new stable release this year?'
[21:26:22] <skunkworks> Jul 24, 2013: LinuxCNC 2.5.3 released
[21:29:38] <nsp> anyone know what this nut is?
[21:29:46] <nsp> i cant find anything on it on the internet
[21:29:50] <nsp> Tr11x4
[21:36:21] <nsp> anyone?
[21:36:31] <scotty_cnc> ?
[21:36:41] <nsp> anyone know what this nut is?
[21:36:45] <nsp> tr11x4
[21:42:27] <r2E4> hi All.....
[21:42:32] <r2E4> Anyone up?
[21:44:00] <r2E4> 40913 latenncy is good enough?
[21:45:42] <scotty_cnc> i think the wiki says 50000 would yield OK results
[21:48:51] <r2E4> I guess I will load the hard drive then
[21:49:20] <r2E4> 10.04 the latest with the live CD?
[21:50:19] <scotty_cnc> If the max latency is more like 30-50 microseconds, you can still get good results, but your maximum step rate might be a little disappointing, especially if you use microstepping or have very fine pitch leadscrews.
[21:50:34] <nsp> anybody know what a tr11x4 nut is?
[21:51:54] <scotty_cnc> nut for what
[21:53:41] <nsp> for a threaded rod
[21:53:55] <nsp> looks like 11x4 is a thread pattern
[21:55:08] <scotty_cnc> looks like a mini threaded rod
[21:55:26] <nsp> yeah i googled it and saw that
[21:55:37] <nsp> but it looks like its only available from some chinese company
[21:55:44] <scotty_cnc> yeah
[21:55:46] <scotty_cnc> look slike it
[21:56:14] <scotty_cnc> screwtech
[21:58:20] <scotty_cnc> worlds smallest cnc
[22:00:31] <nsp> im trying to make this annirouter
[22:01:13] <r2E4> I am using AC servos on my machine if that matters.
[22:01:43] <nsp> http://www.instructables.com/id/The-AnniRouter-v02body-only/
[22:06:31] <r2E4> Ubuntu is installing now. 10.04 LTS
[22:06:46] <r2E4> To get my Hitachi VM40 up and running.
[22:07:51] <r2E4> ANyone using Linuxcnc on commercial VMC?
[22:08:04] <Tom_itx> several are
[22:08:55] <r2E4> bought the machine got back in my shop, paid 6,000.00 for it and the controller is fried.
[22:09:08] <r2E4> They guy said, thats the chance you take.
[22:09:15] <Tom_itx> good candidate for linuxcnc
[22:09:59] <r2E4> I'm worried about the servo amps though.
[22:10:12] <r2E4> Most of the docs are in Japaneese.
[22:10:23] <Tom_itx> there's good help here
[22:10:40] <r2E4> I bought the mesa cards
[22:10:47] <r2E4> 5i25 and 7i77
[22:10:49] <Tom_itx> good call
[22:12:03] <r2E4> They wanted 7,000.00 to retrofit it with a new pc based control.
[22:12:06] <Tom_itx> http://www.youtube.com/watch?v=mxxdq6y8z8M
[22:12:12] <Tom_itx> there's a well talked about conversion
[22:14:42] <nsp> anybody here build this?
[22:14:43] <nsp> http://www.instructables.com/id/The-AnniRouter-v02body-only/
[22:15:37] <scotty_cnc> sweet 5 axis
[22:16:18] <r2E4> Gotta reboot this ubuntu to get linuxcnc running.
[22:18:04] <r2E4> with the LTS whats roots pass?
[22:18:54] <r2E4> shutdown -r now spits "Need to be root"
[22:19:24] <scotty_cnc> cant you do a sudo or something
[22:19:35] <scotty_cnc> cant ya just reboot through the gui
[22:22:14] <r2E4> I sudo added password for root.
[22:22:17] <r2E4> bizarre
[22:22:31] <r2E4> rebooting now. c-ya
[23:35:36] <R2E4_> anyone know how to get 5i25 in pncConf?
[23:35:49] <R2E4_> and the 7i77
[23:42:08] <R2E4_> I fouind the update files
[23:50:29] <eric_u_cnc> r2e4 there was something on the mail list about the xml files needed
[23:52:02] <R2E4_> Yeah, I got them now.
[23:52:11] <R2E4_> thanks
[23:52:20] <eric_u_cnc> do you have an r2e4?
[23:52:30] <eric_u_cnc> that's what I'm working on
[23:52:37] <R2E4_> Seemed to have misplaced my 7i77....
[23:52:56] <R2E4_> Yeah I have an R2E4, boss 9 BP
[23:53:42] <R2E4_> Rewired the iron for 220 single phase and put a VFD on it. Runs great.
[23:53:55] <eric_u_cnc> mine was gutted
[23:54:03] <R2E4_> It is crazy accurate
[23:54:08] <R2E4_> Oh yeah?
[23:54:16] <eric_u_cnc> no electronics
[23:54:37] <eric_u_cnc> unless you count switches
[23:54:38] <R2E4_> I bought the mesa cards for it, then when I got it powered up up, everything worked.
[23:54:56] <R2E4_> Was the servos still there?
[23:56:22] <R2E4_> I am using CAM and drip feeding it.
