[03:07:12] <spasticteapot> alex_chally: alex_joni: Hello?
[03:40:48] <alex_chally> hi spasticteapot
[03:40:55] <alex_chally> i am not really here becuase I am doing homework
[03:40:56] <alex_chally> but whats up?
[03:41:05] <spasticteapot> If you're not here, then who's talking?
[03:41:06] <spasticteapot> :D
[03:41:15] <spasticteapot> I was hoping to ask how your CNC machine was coming along.
[03:41:18] <alex_chally> i wonder if my professor will notice if I put "magic" as a reason in the middle of a proof
[03:41:24] <alex_chally> spasticteapot, getting along actually
[03:41:33] <alex_chally> I am making the thrust bearing support for my Y axis lead screw
[03:41:41] <alex_chally> after that is done I make an identical one for the X axis
[03:42:10] <alex_chally> then I just have to sort out X axis ballnut mounting, mounting the electical cabinet and installing all the electronics
[03:42:13] <alex_chally> then actually wiring everything up
[03:42:18] <alex_chally> hmm
[03:42:22] <alex_chally> maybe I am not so close?
[03:42:37] <spasticteapot> Eh, that's not so bad.
[03:42:44] <spasticteapot> Are you building your own electronics?
[03:43:15] <alex_chally> well, I am not like growing my own gallium for transistors or anything, but yes
[03:43:35] <alex_chally> I am doing most of the electronics diy from the component level
[03:43:44] <alex_chally> buying drivers and stuff, not making them from scratch
[03:45:05] <alex_chally> oh, and that is of course for 2 axis functionality, then I start on making the Z axis mounts and stuff
[03:45:29] <spasticteapot> Have you assembled the electronics yet?
[03:45:43] <spasticteapot> That's usually the stage in a project where I make the really expensive mistakes. :)
[03:50:17] <alex_chally> spasticteapot, I have gotten all the drivers and motors working on the bench, with the correct power supply
[03:50:20] <alex_chally> but never wired proper
[03:50:34] <alex_chally> as in, in the exact configuration it is going to run in
[03:51:12] <alex_chally> I need to get a bit of sheet steel for a subpanel, and as soon as I do that I am going to drill and tap it, and then add the electronics
[03:51:21] <alex_chally> figure out the wiring after I place everything
[03:51:36] <spasticteapot> Well...hurry up so I can trade you my amp for some speaker boxes!
[03:51:37] <spasticteapot> :D
[03:59:57] <Birdman3131> Birdman3131 is now known as birdman3131|zzzz
[05:17:20] <ries> ries is now known as ries_away
[06:58:33] <L84Supper> http://cgi.ebay.com/Vertical-Machining-Center-Matsuura-RAIII-VMC-No-Reserve-/220641337544?cmd=ViewItem&pt=BI_Mills&hash=item335f3fa0c8
[07:02:43] <L84Supper> many of these CNC centers on ebay are selling for less than the price of moving them
[07:04:25] <archivist> suppose they have been worked till they need replacing and people are frightened of the costs to get then running
[07:05:52] <L84Supper> this one is running, the ones we spotted yesterday came back with: "Is this machine fully functional?" Answer: "I dont know"
[07:06:58] <L84Supper> the controls are always the worst part, I can't believe how bad some of the controllers are
[07:08:08] <L84Supper> this one must hold 25 tools!
[07:08:23] <archivist> most of the potential buyers would not be considering and EMC retrofit :) so that keeps the cost down
[07:09:06] <archivist> tool changer has 30 slots
[07:09:20] <L84Supper> yeah, I've started talking to some of the used CNC brokers about reviving lots of potential CNC machines for fun and profit
[07:09:36] <alex_chally> L84Supper, my step brother has a machine like that at home
[07:09:45] <alex_chally> it is a fucking beast
[07:10:17] <L84Supper> alex_chally: heh, yeah the pallet size and work range is pretty big
[07:10:59] <alex_chally> L84Supper, it is not even that it has a large envelope or footprint
[07:11:37] <alex_chally> it just feels.. massive when you use it
[07:11:43] <alex_chally> it is good.
[07:12:00] <L84Supper> 10,000lbs and 12' x12' footprint (grunts)
[07:12:03] <alex_chally> although his is running the original controller which has 3 8080 cpus in it
[07:12:11] <alex_chally> L84Supper, eeeeexactly.
[07:12:23] <L84Supper> oh wow, I haven't used those since 1989
[07:12:38] <alex_chally> it has a slightly smaller footprint then the machien center we have at school, but about 1/3 heavier
[07:12:52] <L84Supper> built solid
[07:13:20] <alex_chally> L84Supper, in our older machines at school we have one with an 8080, one with an 8086, a p1 pro 133mhz and a pII 233mhz
[07:13:21] <L84Supper> I've got 3K sq ft of new space and 22' ceilings
[07:13:55] <alex_chally> i want space :(
[07:14:11] <alex_chally> I have a 1 car garage with a electronics bench, a lathe and a full sized mill
[07:14:13] <alex_chally> it is... full.
[07:14:31] <L84Supper> I actually got my space from a co that trades in used CNC centers
[07:14:43] <L84Supper> business in the US is real slow
[07:14:44] <alex_chally> then why are you looking on ebay :p
[07:15:02] <L84Supper> they are all trying to get rich off of each sale :)
[07:15:17] <alex_chally> gah, I wish I had more then 4 hours at a time to work in the shop
[07:15:28] <alex_chally> it is juuuuust enough time to really get into a project for an hour or two, and then stop :(
[07:15:54] <L84Supper> I could buy 5-10 of these for ones they had available
[07:16:30] <L84Supper> http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=280536638408&fromMakeTrack=true&ssPageName=VIP:watchlink:top:en
[07:16:38] <L84Supper> only 3 years old
[07:16:44] <alex_chally> are those steppers?
[07:16:55] <alex_chally> heh, yeah
[07:17:05] <alex_chally> why would someone use 1200ozin steppers?
[07:17:09] <alex_chally> alergic to servos or something?
[07:17:22] <L84Supper> I hate steppers
[07:18:03] <alex_chally> i think hate is a little strong
[07:18:13] <alex_chally> but that is certainly not where I would use them
[07:18:26] <alex_chally> also, USB pc connection
[07:18:26] <elmo40> steppers are less expensive then servos.
[07:18:33] <alex_chally> which means all new hardware for drivers and stuff most likely
[07:18:40] <L84Supper> maybe we can pool some orders and load a container off to you
[07:19:01] <alex_chally> elmo40, yes but at knee mill size I don't really see the point in saving the money there
[07:19:13] <alex_chally> it is not that much different at that size
[07:19:13] <elmo40> true
[07:19:23] <elmo40> but 1200 isn't knee mill size
[07:19:37] <elmo40> well, not for Z anyways ;)
[07:19:45] <L84Supper> I have memories of my childhood with the zip-zip of mighty stepper motors all around me
[07:20:15] <alex_chally> L84Supper, oh yeah, the noise too. I don't think I could handle being in the same room as a bunch of really loud steppers all the time
[07:20:28] <alex_chally> that is actually a great price though
[07:20:33] <elmo40> and servos don't whine?
[07:20:41] <L84Supper> 3 days left on this auction... I bet the price is going to jump since it's almost brand new
[07:20:49] <alex_chally> why do they never put in shots of the ways?
[07:20:51] <elmo40> servos have a higher pitch to them. more annoying then steppers
[07:21:11] <elmo40> alex_chally: because no one thinks they need to show them.
[07:21:20] <alex_chally> elmo40, I find my brain is a bunch better at filtering the more constant pich of a servo
[07:22:10] <alex_chally> elmo40, because I am going to assume that some monkey didn't drop a face mill on the ways :p
[07:22:21] <L84Supper> http://cgi.ebay.com/MAZAK-VQC-20-40B-VERTICAL-MACHINING-CENTER-/120598381067?cmd=ViewItem&pt=BI_Mills&hash=item1c1439420b
[07:22:29] <L84Supper> at least they list the problems
[07:23:33] <alex_chally> L84Supper, yeah, that spindle motor problem scares me
[07:23:40] <alex_chally> that could cost more then the price of the machine to fix
[07:23:41] <L84Supper> I could retrofit with EMC and keep those great control knobs
[07:24:17] <alex_chally> * alex_chally would look for something with a broken CRT or something like that
[07:24:39] <L84Supper> heh, unless I find a deal on a spindle
[07:25:37] <L84Supper> still the 3 axis positioners are worth 1.5K
[07:26:00] <archivist> just get an air con man to refill the freon
[07:26:49] <alex_chally> how many HP does that thing have on the spindle if they need a freon system to cool the motor?
[07:26:53] <alex_chally> it only goes 4krpm
[07:26:54] <L84Supper> <-- has gauges and a freon license
[07:27:06] <alex_chally> L84Supper, heh, in that case
[07:27:35] <L84Supper> it might be due to undersizing the motor and then requiring the cooling
[07:27:44] <alex_chally> "4) The machine has a problem with the monitor, when it is first started the machine is blank, but after the unit heats up you have to restart the machine and the monitor comes on. (The machine does not like real warm or real cold weather.)"
[07:27:54] <alex_chally> that just sounds like bad resistors or caps
[07:28:03] <alex_chally> given the vintage, i would bet nearly blown caps
[07:28:34] <L84Supper> it would get a new PC controller off the bat
[07:29:29] <Poincare> alex_chally: if it's a CRT look for bad solderings near the connectors/drivers for the deflection coils
[07:30:35] <L84Supper> 7) The machine has a RS232 port that is connected to a tape recorder.(The recorder came with the machine from Mazak). It worked OK
[07:31:02] <alex_chally> L84Supper, my stepbrother's matusra has a paper tape reader/writer built in
[07:31:07] <L84Supper> holy crap.... it would be fun to add some old giant tape drives from the 60's for a cool vintage look
[07:31:10] <alex_chally> I want to find some tape for it
[07:32:02] <L84Supper> I need to look for a crane
[07:32:27] <L84Supper> 14' door is my only limitation
[07:33:46] <L84Supper> hmm how do you break 4 tool holders? crashing into the parts or?
[07:35:24] <L84Supper> this one works http://cgi.ebay.com/Matsuura-MC-500V-CNC-vertical-mill-VMC-yasnac-M5G-/190420076055?cmd=ViewItem&pt=BI_Mills&hash=item2c55ebc617
[07:38:00] <L84Supper> http://cgi.ebay.com/Ibag-HF170-2-spindle-40KW-/150458885172?cmd=ViewItem&pt=BI_Mills&hash=item23080c6434
[07:38:11] <L84Supper> Ibag HF170.2 spindle 40KW
[07:44:25] <L84Supper> alex_chally : how does he program his mill?
[07:44:59] <alex_chally> L84Supper, it has a floppy drive
[07:45:04] <alex_chally> and I think a serial port
[07:45:24] <alex_chally> but he has been using a floppy because usb floppy drives work better then usb serial ports
[07:46:00] <alex_chally> L84Supper, honestly it was not bad to use, just a steeeeeeep learning curve
[07:46:12] <alex_chally> like, sit down, read 150 pages, spend a few hours hating it
[07:46:37] <alex_chally> but once you figure it all out it is quite functional
[07:46:40] <L84Supper> lol
[07:46:59] <alex_chally> thank god there was a manual though
[07:47:23] <L84Supper> does it take G-code?
[07:47:41] <L84Supper> or does it haver to be setup in RPN or something?
[07:47:57] <alex_chally> it takes g-code
[07:48:00] <alex_chally> pretty standard
[07:48:12] <alex_chally> a bit... archaic in some of the canned cycles and stuff
[07:48:21] <alex_chally> no r values of course, all i and j
[07:49:06] <L84Supper> I'd spend a few days retrofitting
[07:49:53] <alex_chally> L84Supper, it would be worth the time, and I think there was a good electrical diagram in the manual
[07:50:05] <alex_chally> enough to wire up a breakout board for a paraport and get emc controlling it
[07:50:28] <L84Supper> I wonder what they used for position info?
[07:51:08] <mrsun__> gah dremmel mount milled and i freakin forgot to make room for screws to tighten it :P
[07:51:46] <L84Supper> linear encoders or rotary's on the motor shafts or ?
[07:51:52] <alex_chally> L84Supper, dunnknow
[07:52:03] <alex_chally> I have not gotten all up in it
[07:52:13] <alex_chally> AC servos
[07:52:22] <alex_chally> and a huuuuuge coolant pumo
[07:52:25] <alex_chally> pump
[07:52:30] <alex_chally> like 8hp or something
[07:52:32] <L84Supper> I been buying up deals on optical encoder tapes and readers
[07:53:37] <alex_chally> and that about exauhsts my knowledge of the machine
[07:53:47] <L84Supper> thanks for the info
[07:55:05] <L84Supper> it could make for a nice howto for EMC retrofits
[07:55:36] <L84Supper> take lots of pics
[07:57:11] <alex_chally> i should take more pictures
[07:57:19] <alex_chally> i get distracted by actually working though

[12:57:22] <Jymmm> skunky!
[12:58:05] <skunkworks> !
[12:58:19] <Jymmm> skunkworks: what be happening!?
[12:58:43] <archivist> sad for for cicni fans http://www.28dayslater.co.uk/forums/showthread.php?t=51562
[12:58:47] <skunkworks> trying to wake up. What is on the agenda today?
[12:59:22] <Jymmm> skunkworks: The same thing we do every day Pinky... TRY TO TAKE OVER THE WORLD!
[13:01:13] <skunkworks> heh - thought of you while camping... (wife bought coffee bags (1 cup brew bags)) they worked great. similar to your pot brew bags.
[13:01:40] <skunkworks> kinda like tea bags but coffee
[13:03:29] <Jymmm> Heh, cool. Those are kinda pricy, and I usually just leave the pot on the edge of the fire so a cup is ready whenever I want.
[13:05:12] <Jymmm> MY trick is nice in a pinch too, so you can even use a plain old pot or even a coffee can literally
[13:07:16] <Jymmm> skunkworks: I try to find everyday common sense stuff for disaster planning, one of these days I'll actually write the book I've been planning to for centuries =)
[13:07:33] <skunkworks> heh - neat
[13:08:11] <Jymmm> skunkworks: I saw this yesterday, and kinda pissed me off... such bad uninformed advice... http://shine.yahoo.com/channel/food/the-top-foods-you-should-keep-in-case-of-an-emergency-2046609/
[13:10:07] <Jymmm> NEVER had nuts in a disaster kit, they go rancid. Even if vacuum packed.
[13:10:21] <Jymmm> s/had/put/
[13:10:42] <skunkworks> although in an emergancy situation - I don't know if I would be worried about coffee...
[13:11:11] <Jymmm> Almost all of the foods mentioned in that article had high sodium content, which will make you drink more water that you may not have.
[13:11:34] <Jymmm> skunkworks: Well, do you know the #1 thing you need to have to survive a disaster?
[13:11:45] <cradek> surely it's coffee
[13:11:54] <cradek> and jumper cables
[13:11:58] <cradek> wait, that's 2 things
[13:12:07] <cradek> also, good morning :-)
[13:12:08] <Jymmm> cradek: (That's #3 behind the tequilia =)
[13:12:12] <cradek> ha
[13:13:29] <Jymmm> cradek: G'Morning to you too =)
[13:14:38] <Jymmm> Well, the #1 thing is a level head. Many panic, have high anxiety, etc. You could have all the supplies in the world and if you don't have a level head about your situation, most of those things aren't going to do you much good.
[13:15:11] <Jymmm> If something like coffee, a deck of cards, etc help you maintain a level head as "creature comforts" so be it.
[13:15:37] <cradek> well vanessa says it's peanut butter. she probably knows more than you because she's writing for ... yahoo.com
[13:15:41] <Jymmm> Nothing worse than sitting around in the dark with a wandering mind.
[13:16:22] <Jymmm> lol, well Vanessa can kiss my black ass!
[13:16:46] <Jymmm> and no, I'm not black.
[13:18:46] <Jymmm> and I've tested the tuna stored for 2years, the can leaked.
[13:19:11] <Jymmm> so did other canned foods.
[13:19:37] <Jymmm> make that 18 months
[13:22:05] <Jymmm> Funny thing, Hormel Spam didn't have an expiration date (they do now as of 2yrs ago), I called them up and they said it has an indefinite shelf life if the can has not lost it's seal.
[13:22:53] <skunkworks> isn't anything that is going to last more than a few years have a good amount of salt in it?
[13:23:08] <Jymmm> the bad thing is lately they have had much higher sodium in them than they used to, so again you are drinking more water. So be sure to get the LITE version.
[13:23:50] <Jymmm> skunkworks: Most things, yes. There are some that don't through new types of shelf-stable packaging.
[13:26:10] <Jymmm> skunkworks: There's the whole MRE and dehydrated stuff, but I try to find off-the-shelf everyday items when I can just as a good resource.
[13:27:00] <genehacker> spam has an indefinite shelf life?
[13:27:15] <Jymmm> Most MRE's I think taste nasty, I try a new one every few months hoping that I'll find one that actually tastes good.
[13:27:32] <Jymmm> genehacker: ...if the seal of the can has not been broken.
[13:28:25] <genehacker> so basically if one kept it at room temperature conditions for all eternity the only decay problem the spam would have would be proton decay?
[13:29:11] <Jymmm> Oh fyi... the gum in MRE's is also a laxative. Because that crap will back you up something fierce!
[13:29:34] <ries_away> ries_away is now known as ries
[13:29:52] <Jymmm> genehacker: The US Gov has had stores of spam that are 50yo
[13:30:38] <skunkworks> that just sounds bad.
[13:30:45] <genehacker> do the cans contain any tin in them?
[13:31:15] <Jymmm> skunkworks: I know but it kept our guys alive in WWII (iirc)
[13:31:35] <skunkworks> right
[13:31:36] <Jymmm> genehacker: I doubt it, specially lined aluminum that I know.
[13:31:41] <genehacker> tin is weird, it can turn to dust below a certain temperature, but only very slowly
[13:32:14] <Jymmm> spam is cooked inside the sealed can.
[13:32:44] <genehacker> hmm..., but the cans are made of steel?
[13:33:02] <Jymmm> genehacker: specially lined ALUMINUM
[13:33:10] <genehacker> aluminum?
[13:33:20] <genehacker> the cans might decay before the spam does!
[13:33:26] <Jymmm> genehacker: a non ferus metal
[13:34:14] <genehacker> aluminum doesn't have a fatigue limit, so if the cans undergo thermal or atmospheric cycling(airplane cabins suffer from this problem), they will eventually break
[13:35:03] <genehacker> might take a hundreds of years, but it will happen
[13:35:14] <Jymmm> genehacker: Go buy this http://www.thebookofspam.com/
[13:36:16] <birdman3131|zzzz> birdman3131|zzzz is now known as Birdman3131
[13:38:03] <Jymmm> I love these little cans, perfect serving size for one or two people, but just as expensive as the regular size cans http://en.wikipedia.org/wiki/File:Spam_with_cans.jpeg
[14:25:35] <skunkworks> woohoo - 16X2mbs (we used to have 5X512
[14:25:36] <skunkworks> )
[14:27:43] <Jymmm> skunkworks: don't make me slap you with a 300 BAUD modem!
[14:28:22] <skunkworks> well - we are sort of out in the boonies.
[14:28:57] <Jymmm> cable?
[14:29:03] <skunkworks> yes
[14:29:31] <Jymmm> comcast?
[14:29:44] <skunkworks> charger
[14:29:47] <skunkworks> charter
[14:30:06] <Jymmm> I *think* they filter, just be aware of it.
[14:30:24] <skunkworks> well - this is a business...
[14:30:34] <Jymmm> so?
[14:30:39] <skunkworks> there shouldn't be torrents or porn going on here..
[14:30:43] <skunkworks> :)
[14:30:55] <Jymmm> who said anything about that?
[14:31:16] <skunkworks> maybe I don't know what you are talking about then. :)
[14:32:13] <Jymmm> Sometimes they like to filter/throttle various traffic, even VoIP
[14:32:24] <JT-Work> what does 16X2mbs mean?
[14:32:41] <Jymmm> JT-Work: 16Mbps download, 2 Mbps upload
[14:32:49] <skunkworks> right
[14:32:55] <JT-Work> ok
[14:32:56] <skunkworks> ah
[14:33:59] <Jymmm> JT-Work: Or, 2MBps download, and 250KBps upload
[14:34:32] <Jymmm> Or in his case 0 across the baord
[14:35:13] <skunkworks> 2MBs would be awesome.
[14:35:29] <Jymmm> skunkworks: That's what you have
[14:36:25] <Jymmm> I think I have 18/1
[14:36:55] <skunkworks> heh - yes I do. (never thought about it like that)
[14:37:16] <JT-Work> I have 256kbit x 128kbit
[14:37:20] <Jymmm> skunkworks: =)
[14:37:41] <JT-Work> better than my old dialup at 49k
[14:37:44] <Jymmm> JT-Work: Hey it's better than dialup connection or speed
[14:37:59] <skunkworks> better than satellite also. IMHO
[14:38:10] <Jymmm> for latency yeah
[14:38:27] <skunkworks> yes
[14:38:33] <JT-Work> yea, when I get that speed it is nice but being a wireless radio line of site connection sometimes it sucks
[14:38:52] <Jymmm> JT-Work: you're on microwave?
[14:39:15] <JT-Work> don't think it is a microwave
[14:39:26] <Jymmm> JT-Work: radio dish on roof?
[14:39:51] <JT-Work> antenna on my tower at the top of the hill behind my house
[14:40:24] <Jymmm> JT-Work: (Microwave), Yeah, you'll get the latency we're talking about with satellite
[14:40:36] <JT-Work> a rectangle looking thing with a cat 5 cable down to my shop
[14:40:37] <skunkworks> my uncle has the same setup - he is having issues with it. The trees betweeen him and the base are gettting bigger.
[14:41:00] <JT-Work> I have the same problem with trees or squirrels or something
[14:41:02] <elmo40> plus, when it rains...
[14:41:12] <Jymmm> Yeah, Wifi/Microwave/Satellite don't like water (leave of trees)
[14:41:21] <Jymmm> leaves
[14:41:36] <elmo40> citizens have the worst frequency spectrum. the best ones are consumed by military
[14:41:45] <Jymmm> can go thru concrete no problem, just not water.
[14:42:37] <elmo40> anyone use the gcode plugin for Inkscape?
[14:42:44] <skunkworks> well - satellite was better than dialup... But almost any other option is better. (I didn't have any options - so it worked well for me)
[14:42:57] <elmo40> should a 2200 node image take more then 5min to convert on an Intel i5 computer?
[14:43:41] <madsci44> no
[14:43:46] <Jymmm> elmo40: ask the magic 8 ball
[14:44:32] <madsci44> I've done that many nodes on old p4's and never took quite that long - but then there are more than one exporter plugin so idonno
[14:44:34] <Jymmm> 2200node via inkscape, I'd say yes.
[14:44:51] <elmo40> ok, done. 7min.
[14:46:07] <elmo40> 542KB file :/
[14:47:08] <madsci44> does yours convert curves elmo?
[14:51:18] <elmo40> I see I and J curves, so that would be a yes
[14:51:22] <elmo40> it isn't all points ;)
[14:51:47] <madsci44> yeah that would take longer :) mines the old points/lines only one
[14:52:46] <elmo40> what do you use?
[14:58:14] <madsci44> Its just the old first one they made on that page with the different links and descriptions - it only does line segments
[14:58:54] <madsci44> works ok for my stuff, easy to modify to generate the extra codes i needed
[15:00:09] <madsci44> I originally got it from here ; http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?InkscapeHowto the versions towards the bottom
[15:02:46] <madsci44> the only thing i would add if i knew enough python would be a way to sort the the paths
[15:07:22] <elmo40> such as, what part to machine first?
[15:08:16] <madsci44> yeah
[15:10:52] <elmo40> that HowTo is very old ;)
[15:11:06] <madsci44> no doubt
[15:11:12] <madsci44> what are you using?
[15:13:05] <elmo40> the dev 1.6 version
[15:13:22] <elmo40> if I remember correctly, the 1.5 version had macros in it.
[15:13:31] <elmo40> this one doesn't...
[15:14:20] <madsci44> i should go try that again - back in the stone age when i first tried i didnt get very far with that one
[15:20:13] <elmo40> it has turned out rather well
[15:20:16] <elmo40> I am impressed
[15:23:07] <elmo40> madsci44: here
[15:23:09] <elmo40> http://www.cnc-club.ru/forum/viewtopic.php?f=15&t=35&start=0
[15:23:13] <elmo40> latest 'stable' is 1.5
[15:26:24] <madsci44> cool
[15:38:32] <tom3p> its 3D too !? i didnt think inkscape was 3D but heres a boat hull (note: it's tagged as buggy) http://www.cnc-club.ru/forum/download/file.php?id=153&sid=ac014ff14c21705f1b2f2af60ac65226&mode=view

[16:03:30] <elmo40> need to do a solid cost benefit analysis to make it worth while
[16:11:07] <alexfloca_> hello all
[16:11:55] <alexfloca_> i have a big problem starting the emc2 with the rt ubuntu hardy on my pc
[16:12:20] <alexfloca_> the regular hardy distribution starts well but the real time kernel fails all the time
[16:13:00] <cradek> hi alexfloca_. how does it fail?
[16:13:39] <alexfloca_> one second i will write exactly what i get
[16:13:45] <cradek> great thanks
[16:14:23] <alexfloca_> meanwhile, te configuration is a intel atom 1.6 Ghz (hyperthreading disabled) with sata hdd and 1 Gb of RAM
[16:14:39] <alexfloca_> i tried to run it with a normal hdd but i get similar errors
[16:14:54] <cradek> that all looks pretty innocent so far
[16:15:03] <elmo40> normal being IDE ?
[16:15:06] <alexfloca_> yes
[16:15:22] <cradek> anymore, pata and sata are equally normal
[16:15:58] <alexfloca_> yes, i had this same problem in the past with a computer and all the problems disapared when running the computer with a normal ide
[16:16:01] <alexfloca_> hdd
[16:19:01] <skunkworks> is it the intel atom? the d945gclf2?
[16:19:26] <alexfloca_> yes it is intel atom, the chipset i think is also d945
[16:20:01] <alexfloca_> one moment i am waiting for the error message
[16:20:28] <alexfloca_> the yellow bar of ubuntu is traveling from left to right and back... :)
[16:20:41] <alexfloca_> for a while now
[16:20:59] <skunkworks> you are booting off of the livecd?
[16:21:00] <alexfloca_> so i get
[16:21:25] <alexfloca_> udevd-event[1274]: run_program: '/sbin/modprobe' abnormal exit
[16:22:28] <alexfloca_> i first tried to make a bootable usb drive afterwards i burned a live cd
[16:22:34] <alexfloca_> i get the same errors
[16:22:45] <alexfloca_> and afterwards the busybox
[16:23:16] <alexfloca_> i tried all possible bios settings combinations and no use, i get the same just the error number changes
[16:23:24] <alexfloca_> from 1274 into eg. 1278
[16:24:02] <alexfloca_> any ideea what it might be?
[16:24:17] <alexfloca_> the normal ubuntu distribution is bootable and i get no errors
[16:24:55] <alexfloca_> the ubuntu 8.04.4 is ok, 8.04 also has some issues
[16:25:10] <cradek> hmm, that's not a good sign then
[16:26:13] <alexfloca_> the emc with ubuntu 6 works fine but i get some real time issues because of the smi
[16:26:26] <archivist_attic> I just did a google, is the hardware too new for 8.04
[16:26:42] <skunkworks> if it is - in fact the d945gclf2 - it is known to work just fine.
[16:26:51] <elmo40> try 10.04 :)
[16:26:54] <skunkworks> (I have used it...)
[16:28:24] <alexfloca_> ok, but how do i get the real time kernel installed on the 10.04?
[16:29:35] <cradek> just download the debs from linuxcnc.org/mozmck/ and install them
[16:30:39] <alexfloca_> ok, i will give it a try
[16:31:39] <skunkworks> there was a guy on here with the d945gclf2 board having issues. It supposidly was the monitor not being detected correctly. (odd)
[16:31:47] <alexfloca_> i just disabled the onboard ethernet controller and i get the busy box directly, no error message, jut the busy box
[16:33:15] <alexfloca_> the monitor works fine, i tried other monitors, and i get the same issue
[16:37:17] <alexfloca_> ok, booted with no splash and the last thing i get is EXT3-fs: Unrecognized mount option "mode=755" or missing value
[16:37:55] <cradek> are you booting the live cd, or is this after install?
[16:38:35] <alexfloca_> booting the live cd, i can't install it
[16:40:05] <archivist_attic> did you do an md5 check on the cd
[16:40:23] <alexfloca_> yes, it is fine
[16:40:41] <alexfloca_> i also get the same issue when booting it from an usb disk
[16:46:36] <alex_chally> i dunnknow if any of you have seen this site
[16:46:37] <alex_chally> http://www.howround.com/
[16:46:41] <alex_chally> kinda cool though
[16:54:27] <genehacker> anyone around here use 3d printers?(reprap is excluded)
[16:55:36] <genehacker> especially any that use the stereolithography process?
[16:56:00] <SWPadnos> is that the real question?
[16:56:27] <SWPadnos> I haven't directly used any, but I have had STL parts made before, as well SLS and other "3d printing" processes
[16:59:50] <elmo40> alex_chally: kinda cool indeed. drilling non-round holes is kinda cool
[17:04:24] <Jymmm> SWPadnos: howdy
[17:04:30] <SWPadnos> hi
[17:04:43] <alexfloca_> hi
[17:07:02] <alex_chally> elmo40, hehe, i actually have a friend who is a beginning mech E student who gave me a small part to make that had like 4 internal pockets with square edges
[17:07:54] <alex_chally> i just kinda looked at the drawing in horror, explained the difficulty and then we redesigned the part
[17:08:47] <elmo40> is it a digital file? I want to see :)
[17:09:14] <Jymmm> alex_chally: what do you think crazy glue is for
[17:10:29] <elmo40> lol
[17:10:33] <elmo40> or welding.
[17:13:09] <archivist_attic> or broaching
[17:13:21] <alex_chally> elmo40, I will see if I can find it
[17:13:40] <alex_chally> we just had to re-arange some things and just cut relief pockets for the corners
[17:13:45] <alex_chally> it was a fairly easy fix
[17:14:13] <alex_chally> any of you guys do any silicone molding?
[17:14:27] <alex_chally> I have been thinking of using machinable wax to make the casts
[17:17:33] <spasticteapot> alex_chally: I've been looking into that myself.
[17:17:45] <spasticteapot> Smooth-On products are generally regarded as pretty idiotproof.
[17:18:23] <spasticteapot> Also, fairly affordable, though it is worth noting that some "1 gallon" kits contain 1 gallon of part A and 1 gallon of part B, while some "1 gallon" kits contain 1 gallon of part A and one ounce of catalytic hardener.
[17:18:46] <spasticteapot> None of them actually contain one gallon of the advertised product, which seems like someone in marketing needs a visit from Mr. Cluebat.
[17:19:15] <alex_chally> spasticteapot, i was thinking machinable wax because after the casting is done I can just recast the wax into billet and make a new mold
[17:19:38] <alex_chally> with one of those vaccumes that sits on a 5 gallon bucket I could probably seriously minimize material loss
[17:19:40] <spasticteapot> Are you moulding silicone or using it to make a mould?
[17:19:49] <alex_chally> moulding silicone
[17:20:25] <spasticteapot> What are you moulding?
[17:20:45] <alex_chally> spasticteapot, well the idea came about after a pot holder got wet and I burnt my hand on a cast iron skillet that had been in the oven for a while
[17:21:07] <alex_chally> so i wanted to make slip on silicone pot handle covers
[17:21:26] <spasticteapot> I'd just get some silicone tape (I know such a thing exists) and wrap it around.
[17:21:26] <alex_chally> obviously I coiuld cast those straight off the pot handles, but I figured if I was playing with silicone I might as well learn how to cast it properly
[17:21:38] <spasticteapot> 2-part silicone is kinda pricey stuff.
[17:22:11] <alex_chally> spasticteapot, I am willing to deal with the price so I can know how to make silicone parts in the future
[17:22:23] <alex_chally> obviously it would be easier to just buy a product like that
[17:22:26] <alex_chally> i bet someone makes it :)
[17:22:28] <spasticteapot> Fair enough.
[17:22:41] <spasticteapot> Anywho, Smooth-On has a variety of products and some tutorial videos.
[17:23:01] <elmo40> http://www.hobbysilicone.com/
[17:23:45] <alex_chally> spasticteapot, I also have been itching to do some ceramic slip casting
[17:23:51] <spasticteapot> I'd go with Smooth-On OOMOO 25.
[17:23:56] <alex_chally> and apparently silicone molds are good for pulling off
[17:24:05] <spasticteapot> It's their "idotproof 2-part no-fuss" product.
[17:24:19] <spasticteapot> It's intended for making molds, but it should work for pot-grips too.
[17:24:43] <spasticteapot> http://www.youtube.com/v/dcRv__zNxYE&autoplay=1
[17:25:03] <spasticteapot> http://www.youtube.com/v/dcRv__zNxYE&autoplay=1
[17:25:05] <spasticteapot> Oops.
[17:25:13] <spasticteapot> Anyway, I think you get the idea.
[17:38:24] <IchGuckLive> good eveneng from the cold side of germany
[17:42:13] <elmo40> how cold?
[17:42:21] <IchGuckLive> <20
[17:42:26] <elmo40> what city?
[17:42:33] <IchGuckLive> K-town
[17:42:39] <elmo40> don't know that one.
[17:42:47] <IchGuckLive> Kaiserslautern
[17:43:10] <elmo40> The current temperature in Ramstein, Germany is 20.0?C (6:55 PM CEST on July 22, 2010). Conditions: Mostly Cloudy. Humidity: 95%. Dew Point: 19.0?C. Pressure: 29.98 in 1015 hPa (Falling).
[17:43:12] <IchGuckLive> in Dresden still 35
[17:43:17] <elmo40> might rain, too
[17:43:35] <IchGuckLive> you got it
[17:44:29] <IchGuckLive> i testet today the python scripts on ther new 2.4.2
[17:45:17] <IchGuckLive> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Simple_EMC_G-Code_Generators
[17:45:42] <elmo40> and?
[17:46:19] <IchGuckLive> at bezel i added Feedrate
[17:47:09] <IchGuckLive> i will also rite a new one for outboring some scketches on base of grid
[17:48:35] <IchGuckLive> is there a number nown how many users from witch country are in use of EMC
[17:49:42] <IchGuckLive> WHY to now it woudt be good to overright these Scripts as Metric/inch woudt be easy with checkbox to do
[17:50:20] <cpresser> IchGuckLive: there is a user-map: http://www.linuxcnc.org/component/option,com_google_maps_insight/
[17:50:35] <IchGuckLive> cpresser: Thanks
[17:52:45] <cpresser> i am just registering myself...
[17:54:56] <IchGuckLive> im not registert so it gives me no numbers
[17:56:13] <IchGuckLive> a lot of scale modell builder in the Metric world love EMC
[18:02:26] <IchGuckLive> By for today
[18:11:46] <mrsun__> argh, image-to-gcode need a "roughing tool" also ...
[18:12:04] <mrsun__> so i can have a bigger mill for the roughing then change to a smaller one
[18:18:11] <alexfloca> hello all
[18:18:24] <alexfloca> herei m again with the intel atom
[18:18:47] <alexfloca> i just installed 10.04 and works great
[18:19:03] <alexfloca> also installed the rt kernel patches
[18:20:02] <skunkworks> neat - so far so good?
[18:20:09] <alexfloca> but when installing the emc deb's i get a error: breaks existing packge emc2 ....
[18:20:16] <alexfloca> yes...
[18:20:24] <alexfloca> so far so good
[18:20:41] <alexfloca> but i get this error and emc wont start
[18:24:45] <skunkworks> (I have not played with installing the 10.04 packages...)
[19:23:11] <mrsun__> for wood, is up or down milling prefered?
[19:23:23] <mrsun__> down should be better right ? .. cause that would cut the fibers insted of splint them of ?
[19:23:47] <moop> moop is now known as moopy
[19:31:35] <frallzor> i dont know the terms
[19:31:43] <frallzor> but imagine a wheel on the ground :P
[19:31:47] <frallzor> that way
[19:36:09] <mrsun__> ye so it turns the same way i feed
[19:36:25] <mrsun__> but alot faster then the feed so it wont act as a wheel ;P
[19:36:50] <mrsun__> ough
[19:36:56] <mrsun__> 844min milling time :P
[19:37:02] <mrsun__> i need a faster machine ;P
[19:38:14] <frallzor> exactly
[19:38:23] <frallzor> thats why i love my 18k rpm =P
[19:38:43] <frallzor> it loves wood
[19:38:45] <mrsun__> have a dremel on it atm
[19:39:22] <mrsun__> but i would like to have a like 1 - 2mm ball nose mill insted of the dremmel ball engraving stuff :(
[19:39:36] <mrsun__> as i could take a bit deeper cuts and lower the speeds insted =)
[19:57:26] <lepton> Does anyone happen to have a pyvcp.xml file that uses "grid" to lay out widgets?
[19:57:57] <lepton> There's some talk of it on old mailing list archives, but no example code I can find on the forum or wiki
[20:21:07] <spasticteapot> Is anyone here familiar with Autodesk Inventor?
[20:34:07] <jthornton> lepton: it is in the manual
[20:34:58] <lepton> grid is?
[20:35:46] <jthornton> if you mean table yes
[20:35:49] <lepton> There's info on tables
[20:36:08] <lepton> I'm interested in grid, as a different widget/feature
[20:36:35] <jthornton> ah, grid afaik is not part of pyvcp
[20:36:48] <jthornton> as in a python grid I assume you mean
[20:37:18] <lepton> yeap
[20:37:36] <lepton> Someone (on one of the many tabs I have open) somewhere was talking about trying it out in pyvcp
[20:37:46] <lepton> but I don't know if anything came of that
[20:38:11] <jthornton> if they did they would have to add it to pyvcp afaik
[20:38:30] <lepton> Yeah, seems like it
[20:38:40] <lepton> So I think we can safely assume it's not in there
[20:39:24] <lepton> Fortunately I can do what I need to do with just tables, but grid would be neat for making things... more pretty
[20:39:35] <lepton> Because if there's one thing a CNC controller needs to be, it's pretty
[20:39:56] <lepton> real time control, modbus, ladder logic, that's all secondary
[20:39:56] <lepton> :P
[20:40:00] <jthornton> you can do the same thing and be pretty with hbox and vbox
[20:40:08] <lepton> That's what I'm doing right now
[20:40:20] <lepton> I'm having trouble with justification of different elements, though
[20:40:43] <lepton> For example, if I'm using hbox to arrage 3 LED indicators, and I want one left justified, one centered, and one right center justified
[20:40:48] <lepton> I can seem to pull that off
[20:40:55] <lepton> but then I'm not never adept at xml
[20:41:02] <lepton> very*
[20:41:28] <jthornton> actually the table is a grid... just looking at the code
[20:43:44] <jthornton> you might have to put spacer containers or something to get that...
[20:45:16] <lepton> Yeah, that's what I'm doing right now
[20:45:28] <lepton> It kind of reminds me of making html pages in the 90's
[20:45:32] <lepton> tables everywhere!
[20:46:01] <jthornton> yea, it ain't pretty but it's all we got
[20:47:16] <lepton> Well, it's a few orders of magnitude better than what I've been working with
[20:47:23] <lepton> I'm pretty happy with how our GUI is coming together, all things considered
[20:47:52] <lepton> But it would be cool to integrate more advanced (hopefully pythonic) GUI features
[20:47:54] <jthornton> you could also put each led inside of a vbox with the text below and enough spaces to make it look pretty
[20:48:17] <lepton> I was happy when I realized you could type into a spinbox
[20:48:27] <lepton> I was concerned there wasn't an easy way to type in numerical values
[20:48:28] <jthornton> you could always code something up to do that
[20:48:51] <lepton> Indeed! I'm just unfortunately dealing with a backlog of things that I need to code
[20:49:07] <lepton> not the least of which being an Arduino Modbus Master that integrates with HAL
[20:49:23] <jthornton> for some reason there is a patch for the spin box to make the enter key save the value typed in
[20:49:46] <jthornton> other wise you have to use the arrows to go up one or down one for the number you typed in to "take"
[20:50:18] <lepton> Oh boy, I hadn't noticed that yet
[20:50:21] <lepton> Thanks for the heads up
[22:44:13] <Fox_Muldr> Fox_Muldr is now known as Fox_M|afk
[22:57:37] <lepton> Anyone know a quick and easy way to make text bold in pyvcp?
