[01:28:16] <Guest515> hello
[01:28:42] <Guest515> i have a question
[01:30:43] <Guest515> how can i get "hm2_pci.ko"?
[01:31:31] <Robertz> hello
[01:49:17] <Paragon> hello all would you say that a backlash of 15arcmin is aceptable for a rotary table (home use)?
[02:07:08] <Paragon> btw that is the backlash of a plantary gearbox that I have been offered. The gearbox is rated at 52Nm torque, I was thinking of connecting this as a direct drive to my cheepo rotary table that has really bad backlash in the worm gear. So am I right in thinking that if the backlash is uniform on this gearbox I should be able to cancell it out via EMC2?
[04:18:56] <JymmmEMC> Paragon: You'll never be able to "truely" compensate for poor mechanical backlash within EMC, but it should be able help at least somewhat
[04:19:36] <JymmmEMC> I dont know the numbers, but others might
[04:21:04] <cradek> Paragon: since cutting forces will push it around, there's very little the software can do.
[04:22:08] <cradek> by "the software" I actually mean "any software"
[05:54:54] <raul> can anybody tell me what the driver microstepping parameter is?
[09:35:29] <Paragon> Morning All...
[09:36:06] <Paragon> Thanks for the feedback JymmmEMC / cradek ...
[09:42:14] <archivist> Paragon, arrange for unidirectional against the cutting force gcode
[09:43:49] <archivist> failing that pay £5-10K for a proper rotary ( well that seems the current price range)
[09:49:10] <Paragon> archivist: 5 - 10K ... yeah right ;-)
[09:49:53] <archivist> Paragon, hence ive started making one
[09:50:21] <archivist> in our price range
[09:57:12] <Paragon> 15 arcmin is pretty small right?
[09:57:23] <archivist> yes
[09:57:49] <Paragon> 1 arcmin = 1\60 of a degree
[09:59:07] <Paragon> so 1 arcmin = 0.01666 of a degree X 15 = 0.25 of a degree backlash.
[09:59:25] <archivist> you should not climb mill with backlash anywhere
[10:00:25] <archivist> if that play is constant all round the circle and the gears are in good condition
[10:00:44] <Paragon> I dont think one can get that low back lash with a conventional worm drive on a cheap rotary table can they?
[10:01:25] <archivist> vertex get close, others Ive seen are c***P
[10:03:27] <Paragon> Like the one I have. It grabs or tightens at certain points and is loose at others. I have been unable to take out the backlash. For example the worm can be rotated .25 of a turn to take up the slack :-(
[10:03:55] <archivist> one of the awful ones
[10:06:44] <Paragon> Yeah sure is ... trying to find a picture of it ...
[10:07:12] <archivist> we did a measurement exercise here on all the dividing and rotaries and all but one were baaaaad
[10:10:10] <Paragon> Dam .... At least i am not alone ...
[10:10:23] <Paragon> How about this for an idea ...
[10:10:58] <archivist> I have an angle dekkor and an 8 sided optical prism for checking
[10:12:23] <Paragon> The rotary table I have does not use ball bearings etc. The rotary part sits on top of the body and is held to it by clampling force. This means the metal surface are working agains each other. (if that makes sense) ....
[10:13:23] <archivist> larger surface=more rigid
[10:17:17] <Paragon> I was thinking of mounting the rotary part or either the stationary part or both to a lathe and cutting a number of grooves in a circle the width of some ball bearing that I have. I would then place these balls into the groves and then clamp the two sections together. This would mean that the rotary part mould be sitting on the the ball bearing which would take the axial load. the ball...
[10:17:18] <Paragon> ...bearing would rotate around the groves etc etc .... Hope that made sense ... lol
[10:43:44] <archivist> Im going to have taper rollers so they can be preloaded for zero play
[12:08:33] <anonimasu> hello
[12:49:57] <alex_joni> anonimasu: found your specs?
[13:13:05] <archivist> "I notice that every time I replace a piece of plastic with a piece of metal my CNC machine gets better." classic comment jepler
[13:14:38] <jepler> rare exception: metal triangular nuts replaced with antibacklash acme nuts made from plastic
[13:15:40] <archivist> replace those with ball screws
[13:15:57] <archivist> I know the cost:(
[13:16:15] <archivist> Im still on worn acme
[13:32:05] <skunkworks_> amplifier enable.
[13:32:08] <skunkworks_> heh
[13:40:40] <alex_joni> skunkworks_: ?
[13:58:50] <fragalot> archivist: atleast you already have acme :p
[13:59:18] <archivist> 9 thou backlash
[13:59:23] <skunkworks_> http://cnczone.com/forums/showthread.php?t=67655
[14:00:02] <fragalot> so anyways for my freq gen, i came to the conclusion that i'm better off building from scratch with components that still exist than to use schematics drawn up in 1973 :p
[14:01:14] <archivist> * archivist uses HP toys
[14:01:59] <archivist> I bought a 8038 kit and never finished it
[14:02:04] <fragalot> I can't afford HP toys, but i have found that i can make a freq gen for about $3, excluding parts i have in stock
[14:02:51] <archivist> I cant these days (and they were cheap secondhand when I got)
[14:04:39] <fragalot> you can't "these days", .. I never could, lol
[14:05:43] <archivist> pass your uni course, get good job, then you can
[14:09:03] <fragalot> /OR/ stay in uni, skip all classes, go work at student pay
[14:09:06] <micges> hello
[14:10:03] <micges> with what hal module can I interpolate with some speed position from X to Y ?
[14:12:08] <SWPLinux> micges: limit2 or limit3 probably
[14:12:38] <SWPLinux> or limit maybe
[14:12:57] <SWPLinux> oops, limit1
[14:13:22] <SWPLinux> they provide first, second, or third order limits
[14:15:23] <micges> Thanks
[14:16:21] <anonimasu> alex_joni: oh, I'm just cutting with random feeds and speeds
[14:17:25] <anonimasu> alex_joni: I found some example of feeds/speeds they seem to give me nice finishes
[14:17:34] <anonimasu> alex_joni: I'm ordering some tooling tomorrow
[14:18:09] <anonimasu> need 1,7mm threading inserts
[16:38:16] <jymm> SWPLinux: on the road again?
[16:43:25] <SWPLinux> kinds
[16:43:27] <SWPLinux> kinda
[16:44:01] <SWPLinux> my wife has a conference in Stowe, VT (1/2 hour from home), so I figured I'd join her since the hotel has a hot tub and breakfast is included with the room :)
[16:44:17] <SWPLinux> (actually, they upgraded our room, so we have a jacuzzi tub in the room too)
[16:47:40] <jymm> woohoo
[16:47:57] <fragalot> CANADIANS
[16:47:58] <jymm> SWPLinux: Did you call and see if there's construction going on?
[16:48:21] <SWPLinux> hey - FOSSCamp and the Ubuntu Developer Summits are in Mountain View (Google campus) next month
[16:48:29] <SWPLinux> there is, we knew about it
[16:48:45] <fragalot> I can picture in my mind a world without war, a world without hate. And I can picture us attacking that world, because they'd never expect it. - Jack Handey
[16:48:47] <SWPLinux> but they put us in the clubhouse, which is as far away from the construction as possible
[16:48:58] <jymm> SWPLinux: Cause, iirc you got screwed twice last time
[16:49:18] <SWPLinux> "I remember a bigger, older guy we used to call 'dad'. I guess some things just never leave you" - Jack Handey
[16:49:24] <SWPLinux> heh
[16:49:53] <jymm> SWPLinux: So, you coming out next month?
[16:50:02] <SWPLinux> could be
[16:50:26] <jymm> what is FOSScamp?
[16:50:30] <jymm> or what is FOSS
[16:50:36] <jymm> FIOS I know and want!
[16:50:37] <SWPLinux> maybe I misspelled it
[16:50:49] <SWPLinux> Free Open Source Software ...
[16:50:53] <jymm> ah
[16:51:01] <SWPLinux> like duh! :)
[16:51:03] <fragalot> wait
[16:51:09] <fragalot> you don't know what FOSS is and you're on freenode?
[16:51:13] <fragalot> o.0
[16:51:21] <jymm> I know it as OSS, not FOSS
[16:51:46] <jymm> damn geeks and their acronyms
[16:51:50] <fragalot> lol
[16:51:58] <fragalot> btw, you guys should come to FOSDEM and promote EMC
[16:52:30] <SWPLinux> where's that?
[16:52:36] <fragalot> brussels
[16:52:38] <fragalot> p:
[16:52:40] <SWPLinux> cool
[16:52:51] <SWPLinux> hmmm. cold - February
[16:53:17] <fragalot> it's actually not cold,.. at all
[16:53:32] <SWPLinux> my purpose at UDS would be to see if anyone else is willing to maintain RT kernel packages for us :)
[16:53:34] <fragalot> last year all the windows were open, all the doors, and it was still rather warm
[16:53:41] <jymm> Oh, if you didn't know, SHA-1 is dead...
http://csrc.nist.gov/groups/ST/hash/statement.html
[16:53:52] <jymm> and WPA has been (partially) cracked
[16:54:05] <SWPLinux> saw that
[16:54:35] <jymm> * jymm dusts off the IPSEC man-ewe-l
[16:55:13] <fragalot> Jymm: thats.. a fairly old article isn't it
[16:55:24] <jymm> SWPLinux: SHA-1024 FTW
[16:55:44] <jymm> fragalot: the SHA-1? Maybe, but the cutoff date for the feds is 2010
[16:55:47] <SWPLinux> try that on your ARM-based router!
[16:55:50] <fragalot> Jymm: in computer terms, it's pretty much been like, since the last ice age
[16:56:25] <fragalot> SWPLinux: can be done, it would just.... take forever :p
[16:56:48] <jymm> SWPLinux: you mena like WRT54GL ?
[16:56:50] <jymm> mean
[16:58:32] <SWPLinux> yes, I do
[16:58:45] <SWPLinux> it would slow things down a bit
[16:59:19] <jymm> SWPLinux: Well, guess I'm ust gonna have to find an alternative then.
[16:59:55] <jymm> SWPLinux: I just added a new AP to expand coverage, so eh
[17:00:58] <jymm> SWPLinux: But.... maybe it's time to move to n too.... I think an Apple Airport might have the balls for it, but not sure.
[17:01:21] <jymm> SWPadnos: else, could just setup a macmini
[17:08:07] <Paragon> logger
[17:08:42] <Paragon> Dam forgot the log command ...
[17:08:43] <archivist> logger_emc: bookmark
[17:08:43] <archivist> Just this once .. here's the log:

[17:09:02] <Paragon> Thanks archivist
[17:14:06] <toastatwork> fffff
[17:50:18] <fragalot> ddddd
[18:12:32] <jymm> logger_emc: Pale Ale
[18:12:32] <jymm> I'm logging. I don't understand 'Pale Ale', jymm. Try /msg logger_emc help
[18:12:59] <jymm> eeeesh
[18:18:38] <fragalot> lol
[18:40:26] <toastatwork> who doesn't understand pale ale?
[18:40:30] <toastatwork> IT IS NOT THAT HARD
[18:41:26] <archivist> * archivist needs to taste some
[18:57:06] <Rap2> is anyone using EMC with a Syil controller?
[19:01:43] <SWPLinux> didn't you ask that questin before?
[19:01:46] <SWPLinux> question
[19:02:05] <SWPLinux> the answer is "probably not", since EMC2 is a controller, and I assume the Syil controller is also a controller
[19:02:20] <SWPLinux> and you only need/want one controller (at a time) for your machine
[19:08:54] <Rap2> well the controller requires a computer hooked up with a parrell port, on their web site they mention Turbo CNC, but it does not come with it nor does it come with a computer
[19:09:16] <cradek> what is this Syil device?
[19:09:17] <SWPLinux> anything that TurboCNC can drive can also be driven by EMC2, so I'll bet it will work
[19:09:31] <SWPLinux> sounds like it's a Xylotex/HobbyCNC-like driver box
[19:11:53] <jepler> If syil doesn't provide enough information pre-purchase to allow you to figure out if it'll work with emc2, then my advice is to look elsewhere.
[19:12:10] <Rap2> Syil's CNC converter/controller box. PC connection through parallel port. Power and control for up to 4 steppers.
[19:12:17] <Rap2> thats all the info I have found
[19:12:50] <cradek> jepler is right.
[19:12:52] <Rap2> they moded a BF20 and sell it for 3.5k I was interested in that price range
[19:13:28] <cradek> call or write them, ask what signals it requires over the parallel port and what they do, then go from there.
[19:14:21] <jepler> while tormach may cost more, they give you complete information.
[19:14:24] <jepler> ""
[19:14:26] <jepler> ""Detailed list of input and output pins on the printer port on the PCNC 1100 series II mill.
[19:14:43] <Rap2> I wish I could afford it
[19:14:51] <cradek> tormach are very dedicated to having an open architecture
[19:14:54] <SWPLinux> since TurboCNC can only do step and direction over the parallel port, it's likely that (given enough information from Syil) you can configure EMC2 to run it
[19:17:30] <Rap2> I saw a used Tormach on ebay, should have grabbed it
[19:17:58] <jepler> yeah -- when I say I'd look elsewhere it's not because I doubt emc's capabilities, but because I don't get a positive impression of Syil.
[19:18:16] <Rap2> where would you look?
[19:18:22] <BigJohnT> Gecko
[19:18:58] <jepler> Rap2: I'm not using or looking to get that class of machine, so it's a bad question to ask me
[19:19:01] <Rap2> I want a complete machine
[19:19:14] <BigJohnT> what kind of machine?
[19:19:44] <Rap2> bench top of resonable size.
[19:20:01] <BigJohnT> mill, lathe, plasma cutter?
[19:20:03] <cradek> what do you want to do with it?
[19:20:07] <Rap2> Mill
[19:20:18] <Rap2> mostly work with aluminum
[19:20:28] <BigJohnT> ok, I thought you were just looking for the drives...
[19:20:30] <SWPLinux> mill little stuff, big stuff, fast, slow, accurate ... ?
[19:21:09] <BigJohnT> fast, accurate, cheap.... pick any one :)
[19:21:17] <SWPLinux> if you haven't done it already, you may want to look into the speed and accuracy you can get with the mills you want to afford (I assume you've already looked into work envelope size :) )
[19:21:27] <Rap2> a mahine of the tormach's capacity or slightly smaller would be great.
[19:22:09] <SWPLinux> I may be thinking of a Sieg mill, but I thought the Syil was only ~200 pounds
[19:22:36] <SWPLinux> which is unlikely to be rigid enough to be able to mill very quickly (in Aluminum)
[19:22:42] <SWPLinux> if you want good accuracy ...
[19:22:44] <Rap2> the BF20 moded machine has all its manual controlls and is 152 lbs
[19:23:00] <SWPLinux> yeah, that's pretty puny for milling metal IMO
[19:23:12] <SWPLinux> (I'm not an expert though)
[19:23:38] <BigJohnT> if you can pick it up it won't do much past pcb's
[19:23:42] <Rap2> I want a tormach no doubt.. shipping to Hawaii will put me at 10k
[19:23:54] <SWPLinux> heh
[19:24:04] <cradek> wow, someone who has it worse than me in the midwest
[19:24:08] <SWPLinux> and/or you'll have to wait 6 months for it to arrive
[19:24:19] <Rap2> by banana boat...
[19:24:21] <SWPLinux> I'd bring it as luggage but ...
[19:25:26] <Rap2> I could go out and buy a birdgeport knock off for 5k and mod it.. then I need a phase converter, time and experiance building robots.. none of which I have.
[19:25:58] <cradek> a bridgeport is not a tabletop machine...
[19:26:13] <BigJohnT> your going to turn a bridgeport into a robot :O
[19:26:15] <cradek> for that matter, neither is a tormach really - it's a bed mill
[19:27:11] <cradek> I'm not sure there exists a tabletop machine that will reasonably cut aluminum
[19:27:38] <SWPLinux> yeah, for any reasonable definition of "reasonably" anyway :)
[19:27:43] <Rap2> the local workworking supply shop has a JET knee mill for like 5k.. which I could put in my truck and haul over on the ferry between islands...
[19:28:08] <cradek> IMO, you would not regret getting a knee mill instead of a bed mill
[19:28:12] <BigJohnT> manual mill?
[19:28:13] <cradek> if you have space for it
[19:29:01] <Rap2> yea but a woodworking supply shop sees it as a mill to sell to its customers and probably has no clue wht a bed mill is
[19:29:39] <Rap2> space is another consern.. a birde port would about touch the roof
[19:29:53] <Rap2> I prefer a bed mill
[19:30:05] <Rap2> or a modde Maho 400... hehe
[19:30:10] <cradek> yeah height can be a problem. especially doors.
[19:30:37] <Rap2> I would have to take the table and head off for sure
[19:31:24] <cradek> I am glad I got a knee mill instead of one of the tormach/smithy size bed mills
[19:31:44] <cradek> the height is very handy. I've had the knee all the way down several times.
[19:32:25] <Rap2> I have a small JET knee mill... which is actualy about the capacity of the tormach...
[19:32:52] <cradek> but you need cnc? can you refit it?
[19:34:15] <fragalot> what happened to the days of heating the metal, and then beating the crap out of it till it was shaped to what you wanted
[19:34:40] <Rap2> I thought about it
[19:35:02] <cradek> still very useful for some tasks
[19:35:53] <Rap2> I would want ball screws and would probably drive the kneee by mounting a motor below it in the table so I could direct drive the screw and keep the manual handle
[19:36:01] <fenn> aluminum casting might compensate for a wimpy mill, since you dont have to remove so much material
[19:36:48] <fenn> but that sounds more invovled than you are willing to commit to
[19:37:37] <Rap2> I would get half way done and have a broken mill forever...
[19:37:47] <SWPLinux> hey, that's my job
[19:38:58] <Rap2> the knee screw moves with the bed.... putting the motor in the bottom would mean the motor would have to move with the screw, not sure how to do that
[19:39:31] <Rap2> if I just drive it inbetween the handel then it has to transverse a gear set rather than direct drive..
[20:04:46] <piasdom> hello all
[20:11:51] <piasdom> after reinstalling everything, i can't get emc2 to start...i get
http://paste.org/index.php?id=4246
[20:12:56] <piasdom> is the emc installation correct ? (BDI)
[20:13:02] <cradek> error while loading shared libraries: libGL.so.1: cannot open shared object file: No such file or directory
[20:13:05] <fragalot> /usr/bin/emcsh: error while loading shared libraries: libGL.so.1: cannot open shared object file: No such file or directory
[20:13:32] <piasdom> if that is for me...i don
[20:13:45] <piasdom> 't know what it means
[20:13:50] <cradek> is this a ubuntu installation?
[20:13:57] <piasdom> 8.04
[20:14:07] <cradek> ok, that is not called BDI
[20:14:20] <cradek> did you do anything special concerning the video driver?
[20:14:25] <piasdom> well,emc was installed with ubuntu
[20:15:01] <cradek> right, but that is not called BDI. BDI was an older system that ran emc1 and is not related to ubuntu.
[20:15:08] <piasdom> i had to use chrome
[20:15:17] <cradek> what is chrome?
[20:15:24] <piasdom> for my video
[20:15:51] <piasdom> ./chrome9.83-242-u804.tar.gz
[20:16:04] <cradek> WHAT IS IT
[20:16:07] <cradek> not the filename
[20:16:13] <cradek> I have no idea what chrome is - is it a video driver?
[20:16:22] <piasdom> it fixed my resolution
[20:16:30] <cradek> brb
[20:16:43] <piasdom> thanks
[20:21:59] <jymm> chrome is a browser by google I know
[20:22:06] <jymm> what ELSE is it, I don't
[20:24:24] <SWPLinux> SIS unichrome graphics chipset, most likely
[20:24:42] <SWPLinux> Firefox/Mozilla themes are also called "chromes"
[20:25:03] <piasdom> it installs via or va drivers
[20:25:15] <piasdom> something with a "V" :)
[20:25:32] <SWPLinux> ok, Via Chrome chipset - whichever ;)
[20:26:11] <piasdom> that always give me trouble
[20:26:34] <piasdom> is there a recommended linux video card ?
[20:26:59] <piasdom> mine is on the motherb
[20:27:01] <SWPLinux> anything with a driver ;)
[20:27:05] <cradek> that driver probably messed up the opengl installation on your system
[20:27:22] <SWPLinux> it's ideal to have one with an open source driver which has a package available for Ubuntu
[20:28:08] <piasdom> SWPLinux:just the manufacturers disk for emc
[20:28:36] <piasdom> cradek:but it worked fine before
[20:29:35] <cradek> no, that's not true. you reinstalled because your video was screwed up in a different way
[20:29:45] <SWPLinux> the version of Linux on the BDI disc you have is different from the one for EMC2
[20:29:50] <piasdom> i had to reinstall because my emc2 file menu had no words
[20:30:15] <piasdom> SWPLinux:yes...i download this ubuntu
[20:30:27] <cradek> I thought you tried running from the CD and it worked. If that's true, you do not need this driver, and if you reinstall and not use this driver, it will probably work fine.
[20:30:38] <piasdom> SWPLinux:machine came /w debian sarge
[20:30:41] <SWPLinux> I don't know why the Ubuntu-based disc doesn't seem to have drivers (or doesn't correctly detect the hardware) for your chipset - you may want to check the Ubuntu bug database and file a report
[20:31:07] <piasdom> cradek:worked fine in the live cd
[20:31:30] <SWPLinux> oops, teatime. bbl
[20:32:01] <piasdom> where's this ubuntu bug database ?
[20:32:39] <alex_joni> http://www.google.com/search?q=ubuntu+bug
[20:32:57] <piasdom> cradek:you think i need to reinstall and skip the x configuration ?
[20:33:05] <piasdom> alex:thanks
[20:37:20] <alex_joni> piasdom: what kind of x configuration did you do?
[20:39:02] <piasdom> alex:hit default for all...but added 12?? x 6?? resolution
[20:39:44] <piasdom> one above what i have now 1024 x 768
[20:40:50] <piasdom> no..sorry
[20:41:04] <piasdom> i did that in that chrome thing
[20:41:29] <piasdom> when i got to the desktop....desktop was bigger then my screen
[20:41:42] <piasdom> after the install
[20:42:03] <piasdom> THEN i ran ./vinstall from chrome
[20:42:11] <alex_joni> what is chrome?
[20:42:30] <piasdom> install my via drivers
[20:42:41] <alex_joni> why would you want to do that?
[20:42:54] <alex_joni> you said the LiveCD worked ok..
[20:43:07] <piasdom> beacuse my desktop was hugh...bigger the my screen
[20:43:27] <alex_joni> you don't fix that by installing some via driver
[20:43:28] <piasdom> in the live cd...the destop was big also
[20:43:40] <piasdom> great
[20:44:05] <piasdom> what i was checking in live..was the menu list in wine and emc2
[20:44:40] <piasdom> i didn't worry about the desk size...thought i could fix it correctly...
[20:45:17] <alex_joni> well.. I can't say about you, but here is what I would do:
[20:45:23] <alex_joni> reinstall from the LiveCD,
[20:45:28] <piasdom> but that is the ONLY way i could fine to fix my desktop..whatever else i tried didn't work
[20:45:38] <alex_joni> boot the newly installed system, then try to fix the desktop
[20:45:54] <alex_joni> but only by changing /etc/X11/Xorg.conf
[20:46:01] <alex_joni> not by installing any other drivers, or whatnot
[20:46:27] <piasdom> ok....
[20:47:10] <piasdom> alex:you can change the resoultion in xorg even if the drivers are not installed ?
[20:47:16] <alex_joni> yes
[20:47:25] <alex_joni> there are lots of drivers for X
[20:47:40] <alex_joni> your system surely uses one of them, or else you wouldn't get any image on the screen
[20:47:43] <piasdom> if the resolution is not in xorg...can i just add it ?
[20:47:47] <alex_joni> yes
[20:47:54] <alex_joni> there are 2 things here
[20:48:03] <piasdom> cool :)....i'll do that then
[20:48:08] <alex_joni> you probably told it you want 1280x1024
[20:48:17] <alex_joni> but during startup X tries to talk to the monitor
[20:48:36] <alex_joni> if the monitor doesn't report 1280x1024 as a supported resolution, X will start with 1024x768
[20:49:01] <alex_joni> that will cause your monitor to work in 1024x768, but because you requested 1280x1024, X will make a larger virtual desktop
[20:49:23] <alex_joni> so you have 2 choices: either leave the defaults during installing (no 1280x1024)
[20:49:35] <piasdom> my res was 800 x480 after install
[20:49:50] <alex_joni> or 2). add 1280x1024 during install time, but later you need to fix Xorg.conf so it doesn't try to read data from the monitor
[20:50:00] <alex_joni> 800x480 is a really strange resolution
[20:50:01] <piasdom> ok..
[20:50:06] <alex_joni> maybe you mean 800x600..
[20:50:27] <piasdom> alex:yes
[20:50:59] <piasdom> alex:can i uninstall the drivers ?
[20:52:24] <alex_joni> I don't know
[20:52:32] <alex_joni> never installed chrome or something like that
[20:52:42] <piasdom> alex:thanks for your help
[20:52:47] <alex_joni> yw
[20:53:37] <piasdom> alex:it has a vuninstall
[20:54:48] <piasdom> well,it said it uninstalled the drivers
[20:54:56] <piasdom> but i need to reboot to tell
[20:55:13] <alex_joni> best of luck ;)
[20:55:22] <piasdom> thanks...brb
[21:00:35] <piasdom> well my desktop is hugh again :)
[21:01:03] <piasdom> this is my xorg.conf
http://paste.org/index.php?id=4247
[21:01:58] <alex_joni> what resolution is your monitor in at the moment?
[21:02:19] <alex_joni> (most monitors have an option in the menu where it tells you your current resolution)
[21:03:10] <piasdom> 1280 x 1024
[21:04:05] <piasdom> only other option is 640 x 480
[21:04:18] <alex_joni> wait.. you're not understanding what I am asking
[21:04:30] <piasdom> oh
[21:04:55] <alex_joni> your monitor has some buttons on it
[21:05:04] <alex_joni> besides the power on/off button .. right?
[21:05:06] <piasdom> 640x480
[21:05:12] <alex_joni> ok..
[21:05:32] <alex_joni> that means X only detects 640x480 as the resolution from the monitor
[21:05:56] <alex_joni> if you try to change (in Ubuntu) to 1280x1024 you will get a big desktop but still the 640x480 resolution
[21:06:13] <piasdom> i understand now
[21:06:13] <alex_joni> edit /etc/X11/xorg.conf
[21:06:36] <alex_joni> there is a Section called "Device"
[21:06:40] <piasdom> did you see my xorg
[21:06:43] <alex_joni> yes
[21:06:44] <piasdom> yes
[21:06:51] <alex_joni> Section "Device"
[21:06:56] <alex_joni> Identifier ...
[21:06:57] <piasdom> ok
[21:06:58] <alex_joni> EndSection
[21:07:10] <piasdom> i see it
[21:07:14] <alex_joni> between Identifier and EndSection add the following line:
[21:08:18] <alex_joni> Option "NoDCC" "true"
[21:09:26] <piasdom> ok
[21:09:38] <piasdom> brb...need to add promission
[21:10:05] <alex_joni> promission?
[21:10:13] <alex_joni> ah, permission :D
[21:11:41] <piasdom> now what...reboot ?
[21:12:12] <alex_joni> ctrl-alt-backspace
[21:12:22] <alex_joni> that will kill X, and it will attempt to restart
[21:12:23] <alex_joni> :D
[21:17:43] <alex_joni> guess that broke it :)
[21:39:28] <cradek> ouch [from web bbs] I am getting an unwanted taper from my lathe. I mount a bar of aluminum between centers and take a careful test cut. then I remove the cutter and mount an indicator to run along the cut. I adjust the tailstock for no indicator change. then I cut my part, but am surprised to find that it has a .005 taper!
[21:40:14] <cradek> first answer: maybe your headstock is faulty
[21:40:22] <cradek> second answer: try adjusting the tailstock some more
[21:41:38] <SWPLinux> uh - that sounds like a bad technique to me
[21:41:45] <BigJohnT> third answer: how accurate is your indicator?
[21:41:58] <SWPLinux> turn something with an unknown centerline
[21:42:09] <SWPLinux> adjust tailstock so the edge is now a known line
[21:42:11] <BigJohnT> and how much taper per foot
[21:42:16] <SWPLinux> assume that centerline is now correct
[21:42:17] <SWPLinux> ?!?
[21:42:24] <cradek> BigJohnT: the third answer is right, amazingly
[21:42:48] <BigJohnT> :)
[21:43:07] <SWPLinux> oh, I guess you'd have a cylinder with non-perpendicular ends
[21:45:08] <alex_joni> good night all
[21:45:15] <BigJohnT> night ales
[21:45:15] <cradek> goodnight
[21:45:17] <BigJohnT> alex
[21:45:29] <SWPLinux> see you Alex
