[00:27:22] <pcw_home> any reason you would not upgrade to 2.4.6?
[00:27:41] <Connor2> didn't know 2.4.6 is out... website says 2.4.3

[00:33:00] <Connor> Looks like update manager has it though.. so.. doing updates via that..
[00:33:05] <danimal_garage> hmm yea i'm still getting those unexpected realtime delay warnings after i changed my servo thread speed
[00:33:39] <danimal_garage> it's at 400,000 now
[00:34:16] <danimal_garage> weird, i only get those latency spikes when emc is running
[00:34:29] <danimal_garage> nothing ever shows up on the latency tests
[00:34:45] <danimal_garage> nothing higher than 12,000
[00:34:46] <Tom_itx> bad ram :)

[00:38:33] <danimal_garage> could it be a bad FGPA card?
[00:38:39] <danimal_garage> hold on i'll check
[00:39:28] <danimal_garage> 659k-790k
[00:40:32] <danimal_garage> i left the latency test running for a while with glxgears going and everything.... never saw any higher than 12k
[00:41:02] <pcw_home> Possible but not likely, dont see how it would be cycle rate dependent
[00:41:34] <DaViruz> possibly maybe, probably not
[00:42:29] <danimal_garage> i dont know what else it could be

[01:18:16] <Connor> okay, so, I need to setup my limit switches on my machine.. It's working envelope.. (thanks to my stupidity) is EXACTLY 18"x12" I should have allowed for a little extra.. but.. Well.. I didn't.. so, how does one go about setting up limit switches to achieve the maximum working size... ?

[16:09:53] <archivist> warm, stop moaning :)
[16:10:13] <danimal_garage> it's cold!
[16:10:23] <danimal_garage> i had to put on a long sleeve shirt
[16:10:40] <danimal_garage> and i got the sniffles!
[16:10:53] <pcw_home> we had snow in the SFBA pretty rare
[16:11:05] <danimal_garage> yea i saw
[16:11:15] <danimal_garage> we had some snow around here too
[16:11:37] <danimal_garage> not at my elevation, but not too far off

[16:12:22] <pcw_home> No snow right here but frost and fog together which Ive not seen before
[16:14:15] <danimal_garage> weird
[16:15:12] <danimal_garage> sun's out at leasty
[16:15:14] <danimal_garage> -y
[16:15:22] <danimal_garage> it was pouring last night
[16:18:24] <Tom_itx> start whiddling on some metal, it'll warm up quick
[16:20:11] <Tom_itx> supposed to be 70F today and 36F by next Sat
[16:20:16] <danimal_garage> i am, but it's not
[16:20:30] <danimal_garage> where?
[16:20:35] <Tom_itx> Ks
[16:20:38] <danimal_garage> ah
[16:21:09] <danimal_garage> it never gets much below 60f durring the day here
[16:21:22] <Tom_itx> this year has been really odd
[16:21:32] <danimal_garage> just the mornings and evenings get a little chilly
[16:21:34] <Tom_itx> i left in -14F temps and came back to 74F
[16:21:38] <danimal_garage> lol
[16:22:21] <Tom_itx> the jetstream has definitely dropped
[16:26:00] <danimal_garage> i don't understand why when i'm at 6" diameter in x on my lathe, then i try to adjust my work offset a few thousandths and enter 6.003", it goes to some oddball number like 1.4725" diameter
[16:26:22] -!- maximilian_h [maximilian_h!~bonsai@ulmg-5d846975.pool.mediaWays.net] has joined #emc
[16:26:34] <danimal_garage> why can't it change the work offset to the exact number i enter like it does on my mill for z?
[16:26:44] <danimal_garage> or Z in the lathe for that matter?
[16:27:19] <cradek> danimal_garage: can you give me a step by step of what you're doing?
[16:28:25] <danimal_garage> sure
[16:28:40] <danimal_garage> i enter the work offset and tool offset numbers in mdi
[16:29:07] <cradek> like what mdi commands?
[16:29:54] <danimal_garage> and if it's at x6" for example and i want to make my diameter a bit smaller, i go to touch off and enter 6.003" for the work offset i'm in
[16:30:01] <danimal_garage> g57 g43g7
[16:30:08] <danimal_garage> g43h7*
[16:30:29] -!- adb [adb!~Moldovean@178-211-232-101.dhcp.voenergies.net] has joined #emc
[16:30:58] <cradek> are you intending to adjust the tool X offset or the g57 X offset?
[16:31:28] <danimal_garage> g57
[16:31:48] <cradek> so in the touch off window you select g57 on the menu, and type 6.003
[16:31:58] <danimal_garage> changing the tool offsets works fine, but i dont want to change that because it'll effect every work offset
[16:32:09] <danimal_garage> cradek, yes
[16:32:22] <cradek> when you do that, if you read what it says before you click OK, does it say 6.003 diameter or radius? it depends which mode you've got it in
[16:32:50] <danimal_garage> diameter
[16:32:54] <cradek> also check to see whether you've got "touch off to fixture" or "touch off to workpiece" selected in the machine menu
[16:33:14] <cradek> you'll want workpiece
[16:33:22] <cradek> (assuming your version is new enough to have that option)
[16:33:59] <danimal_garage> i dont see that
[16:34:17] <cradek> what version do you have?
[16:34:21] <danimal_garage> it's 2.3.5
[16:34:34] <cradek> ouch
[16:35:00] <danimal_garage> gotta upgrade?
[16:35:43] <cradek> axis: the units (mm, inch, or degrees) are shown in touch-off; when appropriate, radius or diameter mode is indicated
[16:35:46] <cradek> ^ from 2.4.0 release notes
[16:35:56] <cradek> I'm not sure touch off handles diameter mode correctly in 2.3
[16:36:11] <danimal_garage> i dont think it does
[16:36:18] <danimal_garage> it's definitely wacky
[16:36:31] <cradek> if you switch to radius, does it work right?
[16:36:40] <danimal_garage> i'll check

[16:38:18] <danimal_garage> yep
[16:38:25] <danimal_garage> works ok in radius
[16:38:50] <danimal_garage> yea i'll update when i don't have a bunch of work in que for the lathe
[16:39:15] <danimal_garage> thanks, at least it's a little easier to figure out now
[16:39:37] <danimal_garage> i don't have to keep guessing numbers till i get the right one :)

[16:44:53] <danimal_garage> cradek, do you run your jog in velocity or absolute?
[16:45:15] <danimal_garage> i'm thinking of switching to velocity, i dont care much for all the overrun
[16:45:28] <danimal_garage> i fear for my vice
[16:45:31] * Jymmm smacks danimal_garage and psha with a rainbow flag!
[16:45:36] <danimal_garage> haha
[16:46:03] <cradek> I can't spin the wheel at a speed my mill can't keep up with, so it doesn't really matter for me

[16:47:17] <danimal_garage> same here which is the problem... it keeps going quite a bit after i stop. if i'm not paying attention it'll hit something
[16:47:35] <danimal_garage> i guess paying attention would be a good thing
[16:47:38] <danimal_garage> but still
[16:48:57] <cradek> I agree that sounds 'not good'
[16:50:15] <danimal_garage> your mill probably keeps up quite a bit better
[16:50:25] <danimal_garage> mine's capped at 300ipm now
[16:50:30] <cradek> maybe your biggest wheel jog increment is too big
[16:50:40] <danimal_garage> .100"
[16:50:45] <cradek> try .0001, .001, .05

[16:50:57] <danimal_garage> yea i could do that
[16:51:10] <danimal_garage> really? that's how they usually are
[16:51:12] <cradek> oops I meant .0001, .001, .005
[16:51:16] <cradek> I bet you mean .010
[16:51:21] <cradek> or are you in mm?
[16:51:22] <danimal_garage> it's even marked like that on the pendant (fanuc)
[16:51:28] <danimal_garage> inch
[16:51:33] <cradek> I've never seen .1 inch per click
[16:51:42] <cradek> bbl, gotta run
[16:51:52] <Jymmm> FWIW Wht I've usually seen is they lay out an outter square of panduit, then add a couple of cross pieces internally. Sorta like this http://i56.tinypic.com/2hmh2s1.jpg
[16:52:18] <danimal_garage> every machine i've ever ran was .0001, .001, and .1
[16:52:26] <danimal_garage> adios
[16:55:16] <Jymmm> danimal_garage: So, If i bug the shit out of you more, you'll go buy a $1200 wire marker too?
[16:55:55] <danimal_garage> no
[16:56:10] <danimal_garage> i didnt buy the panduit, i had it from machines i stripped
[16:57:29] <Jymmm> Like I said the other day when you showed me your cabinet, panduit is not cheap stuff
[16:58:13] <danimal_garage> glad i didnt buy it then!

[17:18:13] <danimal_garage> did you feed it after midnight?
[17:18:30] <mrsunshine> nah, thought about frequencies etc :P
[17:18:35] <mrsunshine> if the mobo is close to the driver

[18:45:03] <Tom_itx> yup
[18:45:12] <Tom_itx> that's why we used a counterweight
[18:45:59] <danimal_garage> it was cutting good for a while without it, but after 10 parts or so, it was loosing steam
[18:46:18] <danimal_garage> but it's cutting fast again with the cord

[18:58:57] <Connor> would be nice if something like that for steppers too.
[19:00:14] <L84Supper> maybe with a one to one ethernet connection with the right MAC and tweaked IP stack
[19:00:25] <L84Supper> it would be interesting to try

[19:01:27] <L84Supper> or with a fast switch with priority given to the EMC systems

[19:22:09] <SWPadnos> cool. the Coreboot folks really seem to like AMD these days
[19:22:53] <L84Supper> AMD has a couple of engineers working full time in Beijing on coreboot
[19:23:06] <SWPadnos> great. I didn't know that
[19:23:17] <L84Supper> and they support every new chipset and cpu
[19:23:20] <SWPadnos> they also do little things like publish (most) register specs
[19:23:29] <SWPadnos> the only thing missing on that board is USB3
[19:23:34] <SWPadnos> "missing" I should say
[19:23:56] <L84Supper> yeah, public vs nda docs are about 80-90%
[19:24:13] <Connor> I wish their was a easy way to compare speeds of CPU like in the old days.. I have no idea how to compare that CPU to a Atom to a i5 or i7 etc..
[19:25:12] <Connor> I'm happy with my little dual core Atom board I got a few months ago.. Nice little computer.
[19:25:14] <Tom_itx> yeah, i'm lookin at the d525 but nobody seems to know alot about it
[19:25:23] <SWPadnos> yeah. and with Intel it's even harder. they change which features the chips get, so you have to research the exact model number
[19:25:26] <Tom_itx> d510?
[19:26:03] <SWPadnos> the D525 should be fine. there was a parallel port issue with the D510 and some parport-connected devices, but that has been fixed (AFAIK)
[19:26:24] <SWPadnos> assuming the motherboard actually has the ports you need (be they PCI, PCIe, or parallel)

[19:32:27] <Tom_itx> is there plenty of room for the heatsink?
[19:32:33] <Connor> I'm using the PCI Parport.. I couldn't see the onboard.. but, no biggie
[19:32:51] <danimal_garage> the onboard uses a header on the mobo
[19:32:54] <Connor> Oh yea. and I even mounted 120mm fan to pull air through the case..
[19:33:03] <Tom_itx> inside?
[19:33:05] <Tom_itx> hmm
[19:33:06] <Connor> yup.

[19:37:13] <Tom_itx> is solidstate alot quicker than regular hdd?
[19:37:20] <SWPadnos> yes, by far
[19:37:31] <SWPadnos> depending on which SSD you get, of course
[19:37:53] <SWPadnos> the speed is pretty irrelevant in this application though

[19:38:09] <Tom_itx> do they use sram?
[19:38:15] <SWPadnos> no, they use flash
[19:38:26] <SWPadnos> there's a RAM cache, just like spinning disks
[19:38:29] <Tom_itx> 10k to 100k write cycles?
[19:38:35] <SWPadnos> something like that
[19:38:41] <Tom_itx> hmm
[19:38:45] <SWPadnos> so you turn off swap
[19:38:57] <Tom_itx> not a winblows toy

[19:54:31] <Tom_itx> yeah
[19:58:07] <SWPadnos> you need TRIM support in the OS for that to work well, and I'm not sure that's easily doable in Ubuntu 10.04(.x)
[19:58:50] <SWPadnos> I think if you enable the backports or proposed repositories, there is a newer kernel/ext4 driver that uses TRIM if you add some discard option the /ets/fstab mount line
[19:59:32] <SWPadnos> you should also look up 4k sectors and how to deal with them. the smaller drives may use 512 byte sectors, but may not

[20:48:12] <danimal_garage> as usual, none of anything on that page makes any sense to me
[20:50:52] <danimal_garage> i installed git, that's about as far as i got
[20:52:47] <tom3p> danimal_garage, i'm with you, i've used git to begin a whole new emc2 dir, but never managed any updates or branches

[20:59:34] <tom3p> i thought i had to 'git pull' first ( something like refreshing repositories)
[20:59:54] <tom3p> and that got me some errors i didnt understand at all, so i 'backed away from the controls'

[21:07:21] <SWPadnos> there's a point at which the instructions are no longer about EMC, but may be about machines in general, tooling, or PC or Linux use. At that point, the user is expected to know (or be able to find out about) the "other topic"
[21:08:24] <SWPadnos> there's a table, it has Ubuntu versions on the left and EMC branches on the top. in each cell is the line you use for a given Ubuntu version and EMC branch

[21:08:35] <SWPadnos> gotta run. bbl
[21:08:53] <danimal_garage> you seem to be missing my issue... i do not know which one of those have what i need
[21:09:41] <tom3p> right. where's the 'contents' list for the debs? or the 'whats new' or 'provides'?
[21:09:50] <danimal_garage> exactly
[21:10:04] <pcw_home> 2,5 is what you need, I hesitated with the debs because I dont know what the side effects of installing them are
[21:10:20] <danimal_garage> i need these machines to stay running, i cant just copy and paste stuff and hope for the best.

[21:10:36] <danimal_garage> thanks pcw_home
[21:11:01] <tom3p> danimal_garage, can you describe what feature you expect to find?
[21:11:02] <danimal_garage> i dont think i'll go that route yet if it isnt stable
[21:11:43] <pcw_home> do you have the emc-dev package installed?
[21:11:55] <danimal_garage> tom3p, it's a hal pin for the pid loop that is supposed to quiet it up a bit
[21:12:13] <danimal_garage> i have 2.4.6, whatever that is
[21:12:25] <danimal_garage> gotten from the live cd
[21:12:33] <tom3p> danimal_garage, ok, some kinda filter is enabled
[21:12:55] <danimal_garage> not a filter i dont think
[21:13:05] <danimal_garage> just a different way of "wiring" it
[21:13:13] <danimal_garage> which works better apparently
[21:14:56] <danimal_garage> part of the problem is i guess i don't know what is part of emc and what is part of linux, so it's hard to find instructions on certain things
[21:15:12] <Connor> back
[21:15:37] <danimal_garage> and having absolutely no linux background, it's a bit of a bitch :)
[21:16:02] <Tom_itx> are the ssd mtbf as good as regular hdd yet?

[21:18:19] <danimal_garage> so wait a minute, i'd basically be installing 2.5 if i used git? or would i just be installing that one feature?
[21:19:41] <danimal_garage> if it's 2.5, i mind as well just back up my config files and install it. it doesnt take that long to whipe out the drive and reinstall if it goes wrong
[21:19:54] <Connor> Tom_itx: I belive MTBF on SSD is much better than HD's, the problem with SSD's has been cost.
[21:20:04] <Tom_itx> yeah
[21:20:15] <Tom_itx> well i'm always hesitant to try something new
[21:20:42] <Connor> Well.. For a CNC, backup your conf files and go with it.. they fail, just reload the OS and EMC, and restore your config files.
[21:21:14] <Tom_itx> how much space does ubuntu take?
[21:21:17] <danimal_garage> i suppose i could do that
[21:21:23] <danimal_garage> hold on i'll look
[21:21:29] <Tom_itx> ubuntu / emc
[21:21:43] <Connor> I have a 32 Gb in mine.. I think I have around 28 ot 29Gb Free.
[21:22:05] <Connor> Who's talking to danimal_garage ? We have some sort of net split ?
[21:24:18] <danimal_garage> i was talking to both of you
[21:25:06] <danimal_garage> mine has a 500gb drive, and i have 429gb fre, which doesnt make sense
[21:25:09] <Connor> okay.. Looked like a conversation I only had one side of..
[21:25:27] <Tom_itx> irc can be that way
[21:25:49] <Connor> how much is free after format? 500Gb isn't formated capacity

[22:34:58] <SWPadnos> I have a network called HOME, which I browse through to get to a particular share, and that dialog still says "WORKGROUP"
[22:35:15] <danimal_garage> yea, i was wondering about the workgroup
[22:35:27] <SWPadnos> you should also type in the username in the correct case (like "Administrator"). I don't know if that's still necessary, but I know it was for some time
[22:37:21] <danimal_garage> thanks for the info
[22:37:26] <SWPadnos> sure

[22:42:31] <gx260> What error are you getting?
[22:42:38] <danimal_garage> it's weird, i can access the windows 7 computer and see the shared folders and drives, but i cant open a folder
[22:43:00] <danimal_garage> no error, it just keeps popping up the password/username box
[22:43:00] <SWPadnos> can you access those shares from any other computers?
[22:43:17] <danimal_garage> yes
[22:43:30] <SWPadnos> so you have the workgroup, username, and password all in the correct case?

[22:46:41] <SWPadnos> I have shares on a Windows 2000 machine which I can access with Ubuntu 10.04, so I don't know what might be going on. As you said, it must be an Ubuntu/Win7 thing
[22:46:52] <danimal_garage> i can see the windows 7 machines on the network with the ubuntu machine, but i cannot see the ubuntu machine from the windows computers
[22:47:17] <danimal_garage> (except for xp, that worked fine)
[22:47:19] <SWPadnos> that's a different thing than accessing the Windows shares *from* the Ubuntu machine
[22:47:46] <danimal_garage> yea, i'd be happy with either at this point

[23:07:11] <lwizardl> hello
[23:07:11] <the_wench> hello lwizardl, you have a question?
[23:08:23] <lwizardl> what all formats of files does emc support ?
[23:08:51] -!- OoBIGeye has quit [Ping timeout: 276 seconds]
[23:09:40] -!- OoBIGeye [OoBIGeye!~kent@81-235-188-139-no48.tbcn.telia.com] has joined #emc
[23:10:11] <SWPadnos> lwizardl, emc2 itself only understands G-code, but there are some filters that generate g-code from other file types
[23:10:29] <SWPadnos> such as images, python scripts, STL files, DXF files, etc.
[23:10:42] <archivist> lwizardl, are you asking dialects of g code
[23:11:50] <lwizardl> archivist, well i jus finished downloading the livecd of the modded ubuntu disc to use for my system. But I was wondering what file types such as dxf etc types of file formats can be used in emc
[23:12:11] <lwizardl> SWPadnos, ah ok I am completely new and don't even have the machine built yet
[23:12:32] <SWPadnos> oh. then you have plenty of time to implement^Wwait for the file types you want :)
[23:12:59] <Jymmm> feb 2012 is just around the corner
[23:13:12] <danimal_garage> SWPadnos: re: google link, thanks, i saw that, but i'd prefer to be able to access an ubuntu folder from my windows 7 computer as well
[23:13:29] <SWPadnos> several of them talked about that too
[23:13:30] <lwizardl> SWPadnos, yeah i'm most likely going to be using blender for my 3d stuff and hope there is a filter for that
[23:13:33] <danimal_garage> i usually save files to the ubuntu computer from my windows box
[23:13:47] <SWPadnos> you do have to read through a lot of crap to get to the real question and the correct answer though
[23:13:53] <lwizardl> Jymmm, ?? feb of 2012 why ?
[23:13:54] <Jymmm> 42
[23:14:01] <Jymmm> lwizardl: ask SWPadnos
[23:14:03] <SWPadnos> lwizardl, I don't think there's a direct blender filter
[23:14:19] <SWPadnos> but there is something called the CNC Toolkit, which was released as open source some time ago
[23:14:36] <SWPadnos> it runs in GMax or 3DSMax, but maybe could be modified for belnder
[23:14:49] <lwizardl> hmm
[23:14:58] <lwizardl> SWPadnos, whats feb 2012 ?
[23:15:11] <archivist> fprward planning
[23:15:15] <SWPadnos> possibly the end of the world (according to the Aztecs or Maya or something)
[23:15:27] <lwizardl> I thought that was in november
[23:15:37] <SWPadnos> oh. well in that case it's just a year away :)
[23:15:47] <lwizardl> lol
[23:16:50] <lwizardl> is there a list of filters and what they support reading from ?
[23:17:14] <SWPadnos> there ought to be, but I don't know for sure. some of the filters aren't bundled with EMC
[23:17:27] <archivist> not as simple as "filters" in all cases
[23:17:27] <SWPadnos> you can set it up to run whatever program you want based on the file extension
