[00:12:43] <SWPadnos> I wonder where this extra screw goes
[00:12:52] <SWPadnos> and whether the washing machine will die without it
[01:08:07] <Valen1> Valen1 is now known as Valen
[01:13:13] <Valen1> Valen1 is now known as Valen
[01:28:28] <Valen1> Valen1 is now known as Valen
[01:34:32] <Jymmm> SWPadnos: You know that part that said "WARNING - DO NOT REMOVE"
[01:34:51] <SWPadnos> you mean the one on my desk?
[01:35:27] <Jymmm> Yeah, that one... and the other half of it that fell into the transmission
[01:35:34] <Valen> 's better than those things what say "warranty void if removed"
[01:35:40] <SWPadnos> yeah. what about it?
[01:36:04] <Jymmm> SWPadnos: Whatever you do... DONT HIT THE SPIN CYCLE!!!
[01:36:14] <SWPadnos> hmmm
[01:36:24] <SWPadnos> so putting it on "MAX EXTRACT" is a bad thing now?
[01:36:30] <Jymmm> btw, what was broken with it?
[01:37:03] <SWPadnos> timer, control board, and wax motor
[01:37:09] <Jymmm> no, not at all. it's just that ALL setting are now LEATHAL EXTRACTION
[01:37:24] <Jymmm> whaaaat? 3 things
[01:37:29] <SWPadnos> I also broke an indicator lens when taking it apart, and upgraded the seals to the kind with a drain, so we can now close the door without a lot of mold forming
[01:37:49] <Jymmm> oh, front load?
[01:37:55] <SWPadnos> the wax motor causes a problem on the controller, which I fixed with a resistor and a triac (<$1, instead of $250)
[01:37:57] <SWPadnos> yep
[01:38:12] <Jymmm> wax motor?
[01:38:12] <SWPadnos> the timer has been weird for a while, so it was definitely time ($85)
[01:38:14] <SWPadnos> yeah
[01:38:17] <SWPadnos> they're really cool
[01:38:21] <SWPadnos> checkthe wikipedia page
[01:38:23] <SWPadnos> check the
[01:38:45] <SWPadnos> it's basically a little chamber filled with wax, which expands when heated
[01:38:56] <SWPadnos> that pushes a plunger to lock the door
[01:39:35] <SWPadnos> the actual wax chamber is maybe 1/2 x 1/4 x 1/4 inch
[01:39:56] <SWPadnos> with a little resistove disc welded to it for the heat
[01:40:00] <SWPadnos> resistive
[01:40:05] <SWPadnos> (though the typo is apropos)
[01:40:36] <Jymmm> next time you come out, I'll let you fix the timer on the dryer, it never turns =)
[01:40:50] <SWPadnos> I didn't fix that, I replaced it
[01:40:52] <SWPadnos> :)
[01:41:13] <SWPadnos> and they're not repairable - they use "mushroom caps" to hold it down
[01:41:14] <Jymmm> Like I said... next time you come out, I'll let you fix the timer on the dryer, it never turns =)
[01:41:22] <SWPadnos> (little polastic rods that you melt into domes)
[01:41:24] <SWPadnos> gah
[01:41:26] <SWPadnos> plastic
[01:41:38] <Jymmm> Hey, I hate a heat gun
[01:41:40] <SWPadnos> I'd fix it by putting in the replacement you have waiting for me ;)
[01:41:40] <Jymmm> have
[01:42:28] <SWPadnos> the problem is that you would have to essentially extrude the dome back into a long thin rod, or cut it off and use glue or something
[01:42:37] <SWPadnos> which never seems to work well
[01:43:13] <SWPadnos> we used to use a case like that for our early PocketWizards, but we switched to a screwed-together case at our earliest opportunity
[01:43:27] <Jymmm> Hmmm speaking of surplus.... I went down to that serversurplus today, he would barely give me the time of day and wouldn't bangain even though the ad said "make offer", so I said forget it, $100 for an empty 2U was too much.
[01:44:02] <Valen> pissoff the mechanical timer and put some embded linux device in there with a buttload of triacs
[01:44:17] <Valen> then you can have your dryer email you when its done
[01:44:25] <Valen> better to do that for the washing machine
[01:44:37] <Jymmm> So, I went to Weird Stuff and asked 4 guys if they had any, they all said no. asked a 5th guy, and he found one in the back which was a 8 bay (insteado f4 bay from the ther place) and got it for $50
[01:44:44] <SWPadnos> I'll send you the timer contact diagram, if you'd like to take a shot at it
[01:45:14] <Valen> heh in my "copious free time" TM
[01:45:36] <SWPadnos> probably more than mine at the moment
[01:46:00] <Jymmm> So now I'm the proud owner of a 2U 8 bay sata case
[01:46:11] <SWPadnos> cool
[01:46:13] <Jymmm> and it even has a slim dvdrw drive
[01:46:18] <Jymmm> and floppy
[01:47:18] <Jymmm> and oh gawd... it is *SO* MUCH QUITER than the 1U cases!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
[01:47:31] <Jymmm> QUIETER
[01:47:31] <SWPadnos> heh
[01:47:34] <SWPadnos> MUCH
[01:47:42] <SWPadnos> NO JET ENGINE/FAN UNITS
[01:47:56] <Valen> heh i have a super dodgy 1u next to me atm
[01:48:08] <Jymmm> I could only run the 1U's for 15 minutes before I had to leave, then it take 20 minutes to get my hearing back
[01:48:10] <Valen> its some custom motherboard firewall applience i am trying to update
[01:48:15] <SWPadnos> I had to take out the hard drive coolers from mu SuperMicro 4U/5U case
[01:48:26] <SWPadnos> they're meant for 1U or 2U, and each one of them sounds like a jet
[01:48:37] <Valen> its pretty quiet (comparitivly) but there is no CPU fan and i'm running it with the case off
[01:48:39] <SWPadnos> the four together was unbearable anywhere on the same floor
[01:48:52] <Valen> so i sat a bit of paper over the cpu to the case fan ;->
[01:48:57] <Jymmm> 3x 15,000 RPM Fans @ 56dB each
[01:49:22] <Jymmm> 160db is louder than a damn jet @ 1m
[01:49:57] <Valen> heh cool
[01:50:22] <Jymmm> iirc jet engine is 143db, but I dont know at what distance
[01:50:34] <Valen> there are many jet engines
[01:50:36] <Jymmm> 100m?????
[01:50:42] <Valen> most of the newer ones are "quieter"
[01:50:59] <Jymmm> That's like calling Mj black
[02:03:41] <Valen1> Valen1 is now known as Valen
[02:06:46] <Valen> wow just busted out my new port 80 card on this thing
[02:06:54] <Valen> it makes life soooo easy lol
[02:08:24] <Valen> (this thing is serial console only and bios isnt redirected out to it)
[02:11:36] <Valen1> Valen1 is now known as Valen
[02:13:23] <Valen> I should be getting my new internet today
[02:13:48] <SWPadnos> just in time, it seems
[02:13:57] <Valen> one would hope
[02:14:21] <Valen> wow just busted out my new port 80 card on this thing,it makes life soooo easy lol, (this thing is serial console only and bios isnt redirected out to it)
[02:14:33] <Valen> pretty good investment for $2 or so
[02:16:49] <steve_stallings> steve_stallings is now known as steves_logging
[02:19:21] <Jymmm> echo echo
[02:19:31] <Jymmm> wth is an "port 80 card"?
[02:19:50] <SWPadnos> a diagnostic card that shows the code(s) output to port 0x80 during POST
[02:20:17] <SWPadnos> which can be helpful if you have a list of port 80 codes for a particular machine
[02:20:20] <Jymmm> what's in port 0x80?
[02:20:29] <SWPadnos> it's used for status outputs
[02:20:41] <Jymmm> irq?
[02:20:44] <SWPadnos> at various stages, the BIOS will output different codes to port 80
[02:20:46] <SWPadnos> no
[02:20:49] <Jymmm> base address?
[02:20:51] <SWPadnos> 0x80
[02:20:58] <SWPadnos> out 0x80, AX
[02:21:07] <SWPadnos> or probably AL - only 8 bits
[02:22:25] <Jymmm> http://www.dealextreme.com/details.dx/sku.21997
[02:22:25] <Valen> all I know is its got 2 7 segment displays on it that flash through a set of numbers
[02:22:42] <Valen> and C1 means detecting memory
[02:22:49] <Valen> HAH that is the exact one i got
[02:23:05] <SWPadnos> C1 means that on that motherboard. I don't think the codes are standard
[02:23:08] <Valen> it was hanging at the memory detection, swap some ram around and its all good again
[02:23:21] <Valen> its for a given bios vendor i believe
[02:23:32] <SWPadnos> yeah, and customizable
[02:23:40] <Valen> its actually got a 30 page manual with everything written in it
[02:23:47] <SWPadnos> hmm. that's a good deal. I should probably get one :)
[02:23:56] <Valen> well i swapped the ram around and it all started working
[02:23:58] <SWPadnos> more necessary for a headless unit :)
[02:24:03] <Jymmm> Make it say "FUC U"
[02:24:12] <Valen> they have one that works off the parallel port as well
[02:24:48] <Jymmm> and pcmcia too
[02:25:00] <Valen> that could be handy
[02:26:01] <Jymmm> Damn, I need to get/make standoff's
[02:26:04] <Valen> (i got my card from DX too)
[02:26:14] <Valen> as in PCB mount stuff?
[02:26:15] <SWPadnos> they're friggin expensive to buy
[02:26:30] <Valen> PCB standoffs?
[02:26:39] <SWPadnos> and of course I forgot to include the 3/4" ones I need in my order
[02:26:40] <SWPadnos> yes
[02:27:01] <Jymmm> As in mobo standoffs.... the 2U case has pressed ones, and the ones in the center of the mobo are non exiistant - great way to fubar a mobo
[02:27:03] <SWPadnos> you can get bags of 50 or 100 little 1/4" ones cheap, but get longer ones or other sizes and they're expensive
[02:27:05] <Valen> drop by a computer store, they will probably have a bucket of them you could get a handfull from if you asked nicley
[02:27:09] <SWPadnos> like $1+ each
[02:27:17] <Valen> ahh yeah
[02:27:35] <SWPadnos> I have a bucket of 1/4-ish ones from various cases
[02:27:40] <Jymmm> These are REALLY low profile.... I'll have to make them. I have jar of hardware - nothing comes close
[02:27:51] <SWPadnos> how tall?
[02:27:52] <Jymmm> maybe 1/8" high
[02:27:53] <Valen> oh baby i have an ADSL link light
[02:27:58] <SWPadnos> you'd be surprised what's available
[02:28:16] <SWPadnos> what screw pitch?
[02:28:16] <SWPadnos> err - thread size :)
[02:28:28] <Jymmm> no idea, ut the are no holes in the midle
[02:28:51] <Jymmm> only in four corners
[02:28:53] <SWPadnos> are the existing ones threaded all the way through the case?
[02:29:14] <Jymmm> no blind thread
[02:29:21] <Jymmm> no, blind thread
[02:29:28] <Jymmm> bbiab, TMZ
[02:29:30] <SWPadnos> ok. that doesn't seem to be enough to really grip
[02:29:53] <Jymmm> t-minus 31
[02:30:05] <SWPadnos> TMZ?
[02:33:15] <Valen> back soon (hopefully)
[02:37:45] <steve_stallings> steve_stallings is now known as steves_logging
[02:58:06] <Valen1> Valen1 is now known as Valen
[02:58:25] <Valen> nope no lovin :-<
[02:58:32] <Valen> they say it might be as much as 6 hours before anything starts happening :-<
[02:59:45] <SWPadnos> that's better than the call I got today
[02:59:58] <SWPadnos> "um - you remember how I said your DSL speed would be upgraded within a couple of weeks? ..."
[03:00:24] <SWPadnos> "well, turns out we're out of capacity in your town, so you need to wait until we upgrade the equipment, which could be several months"
[03:01:06] <Jymmm> ack
[03:01:13] <Jymmm> back
[03:01:13] <SWPadnos> the hidden positive there is that they actually stop overselling service at some point
[03:01:22] <Valen> wow
[03:01:35] <Valen> my problem is i'm getting a naked adsl plan
[03:01:40] <Valen> so they cut the voice line
[03:01:46] <Valen> and you get a VoIP account
[03:01:54] <Valen> atm i have no voice line and no VoIP
[03:02:05] <SWPadnos> so it should be quiet around there
[03:02:30] <Jymmm> Valen: what is tis AT&T?
[03:03:00] <Valen> i have my mobile phone interned connection to irritate you lot with
[03:03:17] <Jymmm> call blocking ftw
[03:03:52] <Jymmm> Valen: are you getting at&t u-vers?
[03:03:59] <Valen> I'm in australia
[03:04:03] <Jymmm> ah
[03:04:07] <Valen> we dont have AT&T here
[03:04:30] <SWPadnos> lucky you
[03:04:38] <Valen> what i'm curious about is my sync speed
[03:04:44] <Valen> but the modem dont want to tell me
[03:05:14] <Jymmm> They were going to install VoIP + Leave the POTS as is but they screwed up and I wouldn't let them disconnect the POTS line, so I never got the VoIP. not a big loss
[03:05:39] <Jymmm> Valen: it'll train for at least a week, sometime two
[03:05:57] <Jymmm> after you get sync
[03:07:02] <Jymmm> The one really nice thing about VDSL is you don't need any filters!!!!
[03:07:30] <Jymmm> But if you're getting VoIP shouldn't matter much anyway
[03:11:56] <Jymmm> You know... for the center holes in the mobo, I think I'll grab some of those nylon standoffs that snap in to the mobo holes. It won't be fastened to the case, but at least the mobo won't flex downward.
[05:32:11] <Valen> W0000000000T!
[05:32:16] <Valen> I HAVE REAL INTERNET!!!
[05:33:03] <toastydeath> I can't believe it's real internet!
[05:33:08] <toastydeath> Easy-spread
[05:33:11] <Valen> well it damn well is!
[05:33:18] <Valen> pageloads are like .1 of a second
[05:33:20] <Valen> not 12
[05:34:22] <Valen> peak transfer speeds are somewhat average
[05:34:27] <Valen> but eh i care little
[08:26:23] <Valen1> Valen1 is now known as Valen
[12:37:32] <Valen1> Valen1 is now known as Valen
[14:08:15] <skunkworks_> jepler: get a chance to tune yet?
[14:09:07] <jepler> skunkworks_: nope, life interferes
[14:09:26] <skunkworks_> I hear you :)
[14:11:13] <cradek> I think my machine is coming early (today)
[14:12:18] <archivist> what new toy?
[14:12:29] <Valen> pizza for dinner or soup
[14:12:32] <cradek> mill
[14:12:56] <archivist> make model?
[14:13:39] <cradek> a video of the same model: http://www.youtube.com/watch?v=_UXd9df0-RM
[14:14:03] <cradek> but mine's not in such a shiny condition
[14:14:11] <Valen> looks not small
[14:14:32] <Valen> yours have the tool changer?
[14:14:36] <cradek> yes same
[14:14:48] <Valen> emc know how to drive that style?
[14:14:57] <cradek> yes
[14:15:01] <Valen> nifty
[14:15:09] <archivist> now I know why you are looking at the toolchanger code :)
[14:15:22] <Valen> oooh does yours have the funky green screen controller still?
[14:15:27] <cradek> yes this is one where it cannot put the old tool back in the original pocket
[14:15:37] <Valen> oh ouch
[14:15:39] <cradek> Valen: dead/missing control
[14:16:08] <cradek> emc support for tools moving among pockets is pretty much done, but not merged yet
[14:17:07] <cradek> actually it could put it back in the original pocket, you'd just have to do two tool change motions
[14:17:19] <cradek> that would be gross
[14:17:40] <Valen> it doesnt seem elegant
[14:17:43] <archivist> far faster to use the free hole
[14:18:01] <Valen> oh wow this is nice
[14:18:02] <SWPadnos> it's only a bit faster
[14:18:11] <archivist> lot faster
[14:18:19] <Valen> i can watch youtube videos with it downloading the video faster than i can play it
[14:18:25] <SWPadnos> you leave the carousel where it was, and at aa new toolchange you swap out, move to new pocket, and swap in
[14:18:39] <SWPadnos> so you have to wait for the toolchanger motion and one extra swap motion
[14:19:02] <Valen> probably double and a half the time
[14:19:20] <SWPadnos> it would be nice to have a helper program for loading tools into a machine like that
[14:19:36] <SWPadnos> "I'm loading tool number 4732 into this pocket"
[14:19:39] <SWPadnos> CLUNK - done
[14:19:51] <Valen> http://www.youtube.com/watch?v=2jm4_HikMqk&feature=related
[14:20:01] <archivist> there should never be a wait for carousel to rotate as that should happen during machining time
[14:20:31] <Valen> depends on if you want to keep your tools in their holes
[14:22:06] <cradek> doesn't matter what pocket the tools are in - that's emc's job to keep track of it.
[14:22:29] <Valen> provided you have the super updated nifty version you have been working on ;->
[14:22:47] <cradek> SWPadnos: to add a tool, you can stick it anywhere and put that info in the tool table.
[14:23:03] <cradek> it's easy...
[14:23:10] <SWPadnos> yeah, I was thinking about making it easier
[14:23:35] <SWPadnos> since you don't know where the tools are at any given point, unloading some tool and loading another one would be tedious
[14:23:37] <cradek> can't be much easier - you have to edit the tool table anyway...
[14:23:54] <SWPadnos> well that's the thing - you don't really have to :)
[14:23:58] <SWPadnos> it kind of depends
[14:24:16] <cradek> you at least need a length
[14:24:18] <SWPadnos> you need the diameter and length information, and that's easy to enter by editing text
[14:26:15] <archivist> tools need a barcode or radio tag
[14:26:51] <cradek> some machines use barcodes.
[14:26:53] <Valen> barcode you could do
[14:27:03] <Valen> rfid would probably unbalance the tool
[14:27:08] <skunkworks_> like dis? http://www.electronicsam.com/images/KandT/conversion/toolchangerspindle.JPG
[14:28:45] <Valen> that has a fair few tools
[14:30:56] <archivist> rfid could be balanced and may be more robust, I can see a barcode being scratched
[14:31:14] <Valen> woyldnt bother it
[14:31:27] <cradek> skunkworks_: did that control forget the tools when turned off, or was the barcode just for verification?
[14:31:54] <cradek> it seems like the tool table would have been a (relatively) large amount of memory if it had to remember them all
[14:32:00] <Valen> i reckon put it on the back face of the tool if possible
[14:32:25] <archivist> cradek, or external db
[14:32:38] <Valen> I spose thats the question, where would you put a RFID tag?
[14:32:50] <Valen> a barcode you could etch into the spindle or something
[14:33:05] <archivist> toolholder body
[14:33:22] <Valen> mmm i spose
[14:34:04] <Valen> I spose it would be worth it as a confirmation really
[14:34:20] <Valen> to ensure that you are using the 2mm engraver not the 80mm face mill
[14:34:27] <archivist> cradek, btw my cnc already has a database server on it so its ready :)
[14:34:37] <Valen> you would only have to make that mistake a few times for it to pay for itself
[14:35:06] <Valen> your not really talking about that much data, i mean even if you had a thousand tools I cant see you busting 3 or 4 mb
[14:35:41] <cradek> I was asking about the control on skunkworks_'s machine becuase I think there were barely 4MB of ram in the world when it was made :-)
[14:36:05] <Valen> heh yeah, back then they knew how to do things efficently though lol
[14:36:57] <cradek> I bet the entire control had only a few dozen bytes of ram equivalent
[14:37:06] <archivist> core
[14:37:14] <Valen> probably a bit more than that
[14:37:28] <cradek> not sure if it had core - it was discrete transistor flipflops
[14:37:28] <Valen> even core came in hundred of byte banks
[14:37:36] <Valen> heh the space shuttle runs on core memory still
[14:37:38] <cradek> maybe he knows...
[14:38:18] <Valen> i'm getting lots of packet loss
[14:38:24] <Valen> need to reset the modem i thinks :-<
[14:38:46] <Valen> was hoping to avoid all this
[14:43:23] <skunkworks_> cradek: no tool table. You would issue a Twhatever before it was needed - the chain would read each tool untill it found whatever
[14:43:42] <skunkworks_> very old
[14:43:42] <cradek> skunkworks_: so not even length compensation?
[14:43:48] <skunkworks_> nope
[14:44:04] <skunkworks_> that is why emc is going to be so cool.
[14:44:06] <jepler> advance - scan - advance - scan?
[14:44:10] <cradek> figures - that would be an awful lot of storage (a length for each tool)
[14:44:11] <skunkworks_> yes
[14:44:48] <skunkworks_> it would not pause - it would read the rings as it went by. if it found the tool - it would advance 2 more pockets and stop.
[14:44:57] <cradek> neat
[14:45:15] <cradek> can it physically go both ways (I know there was no point to doing it originally)
[14:45:18] <archivist> if tool missing did it error on looping the chain
[14:45:32] <cradek> heh, doubt it!
[14:45:39] <cradek> it would have to keep a count then
[14:46:24] <skunkworks_> yes - it could go both ways.
[14:46:28] <skunkworks_> but didn't
[14:46:30] <skunkworks_> :)
[14:46:44] <cradek> that will be nicer when using emc - it can know which way to go
[14:47:17] <skunkworks_> it could to a startup and run the tool chain all the way around to know where each tool is :)
[14:47:35] <cradek> it will just remember in the tool table
[14:47:38] <skunkworks_> smop
[14:48:11] <cradek> I think I'm going to have mine home the carousel when the first pocket prep happens
[14:48:31] <archivist> no need to be precise when loading if it can read the chain to locate
[14:48:32] <cradek> or maybe at the first machine on - dunno
[14:48:50] <cradek> archivist: the problem is you can only go one way then - might be a long way around
[14:48:54] <skunkworks_> I would have to add a 'index' sensor on the chain for that.
[14:49:05] <skunkworks_> count from this point
[14:49:15] <cradek> yeah actual position feedback would be nicer, but much harder
[14:49:25] <archivist> no a tool marks the psuedo spot
[14:49:40] <skunkworks_> it has a single sensor that fires when each pocket goes by - but that is it
[14:50:08] <skunkworks_> right - as it was.
[14:51:01] <archivist> spin the chain and any tool can be referenced to the first you see
[14:51:39] <cradek> that's true, if you trust the tool table, you can read any one tool and know the carousel position
[14:51:52] <cradek> (that's not easily done in the current architecture, though)
[14:55:10] <EbiDK|AWAY> http://mirror2image.wordpress.com/2009/07/16/augmented-reality-imitate-art/
[14:57:28] <SWPadnos> put a second sensor track on it, and space the marks on the second track different numbers of pockets apart. Once you pass two of them, you know where you are
[14:58:06] <cradek> true and you could even do that in hal (because you don't need access to the tool table)
[14:58:10] <SWPadnos> right
[14:58:28] <SWPadnos> getting the spacings -> positions info into HAL would be a little tricky
[14:58:30] <cradek> I bet there's an optimal pattern :-)
[14:58:37] <cradek> what a geek-trap that is
[14:58:37] <SWPadnos> fibonacci
[14:58:38] <ilya_> which "convert" do i need to compile documentation with lyx 1.5.3 if "checking for LyX version... 1.5.3 | configure: WARNING: LyX documentation should only be edited with LyX version 1.3.x | checking for convert... none | configure: error: no convert, documentation cannot be built"
[14:59:06] <cradek> I think convert is part of imagemagick
[14:59:41] <jepler> use apt-file to determine what package contains a file, or just type the command name at the prompt if it's a command.
[14:59:46] <jepler> apt-file search bin/convert
[14:59:50] <jepler> imagemagick: usr/bin/convert
[15:00:22] <jepler> maybe the problem of spacing marks on the second trac kis related to the Golomb Ruler problem http://en.wikipedia.org/wiki/Golomb_ruler
[15:00:34] <SWPadnos> yes, it is
[15:01:02] <ilya_> ok
[15:01:04] <SWPadnos> luckily someone made a table for us ;)
[15:01:56] <SWPadnos> but I think a Golomb ruler is "overconstrained" for this application (unless you want to be able to recover from a missing marker)
[15:03:45] <ilya_> cradek: graphicsmagick-imagemagick-compat, imagemagick
[15:03:53] <SWPadnos> imagemagick
[15:04:02] <SWPadnos> it's listed in the build-deps I think
[15:08:58] <ilya_> SWPadnos: heh, no time to read essential docs as always ;)
[15:14:26] <skunkworks_> the easiest would be just to put 3 sensors on it - one index and 2 for quadature. run it around once until you hit the index then you know where you are - create a little up/down counter that turns over at 60
[15:15:05] <SWPadnos> that might reqiure you to move the carousel 59 times before finding the index though
[15:15:39] <SWPadnos> if you use 8(ish) index marks, you['d only have to move between 5 and 10 (ish) times
[15:20:31] <ilya_> OK... i'll change sim-card in the midnight and download that imagemagick, all those 1400 Kb!
[15:20:31] <ilya_> i will build documentation for pleasure
[15:20:48] <SWPadnos> you may need other things too. I'd make a list
[15:21:30] <ilya_> SWPadnos: j/k I can load 30 Mb each 0:00-9:00 for 0.3 USD
[15:21:55] <SWPadnos> sure. I'd make a list of packages to download and do them all during the cheap times :)
[15:22:18] <ilya_> later this day, now, i would better eat a soup,yeah!
[15:23:34] <ilya_> eating, cleaning floors, a life of a handsome men!
[15:23:46] <ilya_> j/k :P
[15:23:59] <SWPadnos> um. yeah.
[15:25:12] <ilya_> sorry
[15:25:57] <ilya_> So, /docs directory actually contains whole `current' documentation?
[15:26:28] <cradek> yes /docs in the git checkout is the current
[15:29:43] <ilya_> cradek: no, `docs' in the $HOME/emc2-2.3.1/docs from emc2_2.3.1.tar.gz
[15:30:13] <cradek> those are the docs that went with that version
[15:30:21] <cradek> I'm not sure what you're asking by "current"
[15:33:32] <ilya_> cradek: those presented at that time
[16:09:51] <Jymmm> SWPadnos: Check out what I got for $50... http://www.cidesign.com/product_detail.jsp?productID=60&region=us
[16:10:26] <Jymmm> from weird stuff
[16:36:02] <skunkworks_> heh these old xseries ibm rackmount servers are pretty cool
[16:36:34] <skunkworks_> this one is a 1.133ghz dual proccessor.
[16:36:50] <skunkworks_> raid installed with 6 drive bays.
[16:37:48] <skunkworks_> old enough to still have drivers for novell 4.11 (don't ask)
[16:38:07] <SWPadnos> if it had drivers for Novell 386, I'd be surprised :)
[16:38:27] <SWPadnos> Jymmm, nice. does it have the SATA-II drive bays?
[16:38:59] <SWPadnos> hmmm. how deep is it, and did they have another one? :)
[16:39:10] <SWPadnos> eek. 26.5"
[16:43:06] <SWPadnos> well. I'm happy with my machining skill (such as it is) today
[16:43:22] <cradek> what did you do?
[16:43:26] <SWPadnos> I managed to tap into this aluminum tube correctly
[16:43:43] <cradek> neat
[16:43:46] <SWPadnos> it's a 7/8 OD / 5/8 ID tube, and I had to drill a 49/64 hole, then tap to 13/16-20
[16:44:19] <SWPadnos> and none of the threads breached the OD, so it must have been pretty well centered and parallel
[16:44:19] <cradek> just figuring out whether 49/64 is between those two numbers is reason for celebration
[16:44:23] <SWPadnos> heh
[16:44:32] <SWPadnos> 48/64 is 3/4
[16:44:45] <SWPadnos> so the outer wall is pretty thin
[16:44:57] <SWPadnos> 7/128 per siide, if I centered it perfectly
[16:45:06] <cradek> nice job then
[16:45:13] <SWPadnos> thanks
[16:45:39] <SWPadnos> now I have to see how to wire the stuff that goes inside, such that the wires stay connected when I screw in the components on the ends :)
[16:57:27] <Jymmm> SWPadnos: Yes, it has all 8 bays + SATAII backplane. Actually I asked 4 ppl if they had any 2U and all said no. When i asked the 5th person, he went in back for a while, then carried it out.
[16:58:05] <Jymmm> SWPadnos: came with a slim DVDRW +FDD too
[16:58:25] <Jymmm> IDE thankfully
[16:59:24] <Jymmm> SWPadnos: What's kinda funny/cool is there is a place for a 9th hdd internally. So you could install OS on it, then use the 8 hotswap as NAS for data
[17:01:40] <Jymmm> SWPadnos: And it is *SO* QUIET compared to the 1U's I have
[18:30:55] <DaViruz> hm, got the bearing out of my noisy servo now, it seems smooth and nice, but the balls rattles alot if i shake it, but i can't feel any excessive play. could the "loose balls" account for the knocking sound it makes when the servo rotates?
[18:31:51] <DaViruz> the servo was nice and quiet until the damn thing fell onto the concrete floor yesterday..
[18:32:22] <SWPadnos> sounds like you're 1 ball short of a full race
[18:32:53] <DaViruz> its sealed, i doubt there are balls missing :/
[18:34:08] <archivist> sealed dont normally rattle
[18:34:33] <DaViruz> the noise also depended on the orientation of the servo. if i held it shaft down it was virtually silent, but if i had the shaft horisontal it made a lot of noise, and shaft upwards it made noise but not alot
[18:35:52] <archivist> could be raceway damage , there will be orientations where the dents are avoided
[18:36:03] <DaViruz> i wish i could just throw the whole thing away and get a new servo off ebay, but there aren't any :/
[18:36:35] <DaViruz> i've tried rotating the bearing with my fingers and loading it in different ways and try to feel if there's damage
[18:36:50] <DaViruz> but it feels smooth
[18:37:14] <SWPadnos> did the motor fall onto the shaft?
[18:37:55] <DaViruz> im not sure really, there is a small dent in the shaft, but the big dents are on the corners of the flange
[18:38:01] <SWPadnos> hmm
[18:38:23] <SWPadnos> what you describe seems consistent with a fall directly onto the shaft, which might have put little dents on the back of the race
[18:38:39] <SWPadnos> when you hold it shaft-down, the shaft and rotor push toward the other side of the race
[18:38:57] <DaViruz> yeah, i was thinking the same thing
[18:39:07] <DaViruz> until i got it out and couldn't feel anything
[18:40:21] <DaViruz> there's virtually no radial play, there is some radial play however, perhaps 0.3mm
[18:40:30] <DaViruz> err, there is some axial play
[18:40:52] <DaViruz> but this servo has probably seen industrial life since 1998 so i guess that is expected
[18:41:50] <archivist> a pair of bearings wont cost much
[18:42:28] <DaViruz> to get the rear bearing out i will have to remove the locator for the encoder, i'm not sure if i want to do that
[18:42:49] <DaViruz> i have no idea if the servo drive depends on correct index from the encoder for commutation or somethiung like that
[18:43:34] <DaViruz> of course it does hold position without revolving at startup so i suppose that's unlikely
[18:43:56] <archivist> encoder still ok after the drop?
[18:44:06] <DaViruz> as far as i can tell
[18:44:21] <DaViruz> the servo still works fine, except for a knocking sound which occurs about once per revolution
[18:44:56] <DaViruz> which would be consistent with a bent shaft :/
[18:45:56] <DaViruz> i should have put an indicator on it and checked runout before taking it apart :/
[18:59:45] <cradek> DaViruz: does it have brushes?
[18:59:58] <DaViruz> no, 3ph ac
[19:00:46] <DaViruz> at least i assumed ac servos were brushless, i may be wrong?
[19:03:51] <DaViruz> hmm, on a second thought it must be brushless
[19:09:43] <turkshea-> turkshea- is now known as turkshead
[19:15:17] <rich66> hey
[22:21:04] <DaViruz> yay, assembled the servo with the old bearings again, and the noise was gone
[22:21:31] <DaViruz> i cant quite figure out how to set the preload on the bearings though, if there's even supposed to be preload
[22:22:08] <DaViruz> if i preload in one direction, it's quite, if i preload in the opposite direction it's noisy, and with no preaload it's noisy
[22:22:27] <DaViruz> which would seem to support the idea that one bearing is damaged in one axial direction
