[00:05:23] <Rob__> anyone use bobcad?
[00:15:16] <Loetmichel> mornin'
[01:57:58] <Loetmichel> hmmm... anyon here can suggest a tool to stream an usb webcam on the mill with the CNC-PC?
[01:58:15] <Loetmichel> so i cam supervise the mill from a different place?
[01:58:37] <Loetmichel> the Desktop is there per vnc, but i am missing the actual work ;-)
[01:59:33] <Loetmichel> and using a webcam display tool and the vnc link is a bit slow AND captures to much of the small screen
[02:00:46] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=13060 <- thats how i do it at the moment
[02:02:27] <Loetmichel> anyone?
[02:10:15] <Loetmichel> hmm, disconnected... did anyone had a suggestion?
[02:13:01] <archivist> no

[02:17:36] <ReadError> my latest project ;)
[02:24:32] <ProxDem> nice
[02:35:36] <ReadError> still want to find a good domestic CF source
[02:35:48] <ReadError> i may try some dragonplate
[02:54:03] <ProxDem> ReadError: must be a mess machining that
[02:54:59] <ReadError> not at all
[02:55:08] <ReadError> shopvac + dustboot + HEPA
[02:56:16] <WalterN> is there a reason why CO2 lasers are generally used for engraving?
[02:56:50] <WalterN> (for laser engraving)
[02:57:00] <WalterN> or are diode lasers just as good?
[03:04:47] <toastydeath> co2 emits primarly in the infrared spectrum, and the lasing cavity is easily made to handle high output
[03:05:19] <WalterN> yeah
[03:05:33] <WalterN> CO2 is something like 1,500nm wavelength
[03:05:34] <toastydeath> it's also VERY easy to cool
[03:05:42] <WalterN> diode laser is 810nm
[03:05:49] <toastydeath> so when you have a 2kw laser, it's not going to overheat when you run it for an 8 hour shift
[03:06:30] <toastydeath> cheap, easy, and effective.
[03:06:33] <WalterN> sure, for larger power outputs, CO2 is the way to go
[03:07:06] <WalterN> for maybe 80 watts or less, diode does not seem too bad
[03:07:47] <WalterN> I'm wondering about the wavelength difference though
[03:08:18] <WalterN> 1,500nm is what most heat radiates at
[03:08:20] <WalterN> or there abouts
[03:08:27] <toastydeath> not really an issue
[03:08:39] <WalterN> 810nm is essentially red
[03:08:48] <toastydeath> absorbancy is the issue, not emission
[03:12:12] <toastydeath> and also, it mostly just affects cut speed
[03:12:32] <toastydeath> you can cut a mirror, it'll just take awhile.
[03:27:23] <diginet> would it be possible to make your own linear motor for a cnc with a linear optical encoder for feedback?
[04:57:37] <Loetmichel> soo, still has about one sec lag but works more or less... ;-) -> http://www.cyrom.org/palbum/main.php?g2_itemId=14199
[07:27:46] <mrsun> sometimes i wish i had a cnc lathe :P
[07:28:01] <mrsun> a job like these excentric bushings i made today would go so much faster :P
[08:31:59] <L84Supper> pcw_home: http://beagleboard.org/Products/BeagleBone%20Black
[08:32:42] <L84Supper> now $45
[08:34:44] <FinboySlick> The two DSPs on it look like they could be great for machine control.
[08:35:51] <Tuipveus> I have atari with 56001 DSP. hahaa
[08:36:09] <Tuipveus> motorola
[08:37:14] <L84Supper> the SOC also has a Programmable Real-Time Unit and Industrial Communication Subsystem (PRU-ICSS)
[08:37:42] <L84Supper> http://www.ti.com/product/am3359
[08:37:51] <L84Supper> Supports protocols such as EtherCAT, PROFIBUS, PROFINET, EtherNet/IP™, and more
[08:38:20] <L84Supper> nice bump to 1GHz, wish they had 1 GB vs the 512MB of DDR
[08:54:51] <mrsun> http://sphotos-g.ak.fbcdn.net/hphotos-ak-ash4/397853_10151554735658648_1784989011_n.jpg mockup of my X/Z axis, anyone got any sugestion on how i should make the Z ? :)
[08:56:21] <jdh> heh, I have those same cheap clamps
[08:57:01] <mrsun> =)
[08:57:13] <frallzor> me too
[09:02:14] <L84Supper> http://www.b3innovations.com/ nozzle smozzle, everyone seem to shy away from making a decent extruder
[09:17:25] <Guest97804> I have a linuxcnc / hal question. Is this the appropriate place to ask?
[09:17:43] <jdh> ask, and find out!
[09:27:49] <Guest97804> does the order of the pins in a net command important ie is "net probe hm2_5i20.0.gpio.035.in => motion.probe-input" the same as "net IN11 <= hm2_5i20.0.gpio.035.in"
[09:28:46] <cradek> the order doesn't matter, but your example muddies your question and I'm not sure that's what you're asking
[09:30:06] <Guest97804> sorry is net probe hm2_5i20.0.gpio.035.in => motion.probe-input" the same as net probe motion.probe-input <= hm2_5i20.0.gpio.035.in"
[09:33:21] <pcw_home> Yes as cradek says, order is unimportant (except the signal must be first)
[09:33:56] <cradek> also be aware that the arrows are comments/documentation and have no meaning except to humans
[09:35:22] <Guest97804> great thanks. I knew the arrows were just for humans but I wasn't sure about the order.
[09:37:32] <pcw_home> since I'm a schematic kind of guy, I think of the net command as making a named 'wire'
[09:37:36] <pcw_home> (probe in this case) followed by a list of connected nodes
[09:38:57] <pcw_home> so the order of nodes is not important
[09:39:46] <Guest97804> helpful analogy, thanks peter
[09:41:41] <pcw_home> Now where's the metadata so the the editor knows the types and directions of the pins/parameters so it can color code them :-)
[11:07:29] <WalterN> L84Supper: poke
[11:20:32] <Connor> cradek: You mean the <=, =>, and <=> doesn't do anything ?
[11:21:10] <cradek> right
[11:27:45] <cpresser> cradek: is it allowed to skip them completely
[11:28:26] <cpresser> eg have "net netname signal_1 signal_2 signal_n"
[11:32:23] <pcw_home> Yep, the <=, =>, and <=> are just for looks
[11:33:14] * cpresser would suggest to drop them in the examples.
[11:33:41] <cpresser> those signs always confused me. until i learned it doesn matter which one you use.
[11:34:08] <ssi> I think they're useful for keeping track of what is intended to be inputs or outputs or bidirectional signals
[11:34:41] <jdh> unless you just got it wrong when you typed it.
[11:34:53] <pcw_home> wheres the color hi-lighting?
[11:35:35] <cpresser> ssi: since each net has only one input, just put in in the first place.
[11:35:47] <WalterN> L84Supper: does laser engraving care about what wavelength is used?
[11:35:49] <cpresser> also its possibel to chose signal names which reflect if a signal is input or output
[11:36:24] <pcw_home> you need a netname, not a pin as the first parameter
[11:36:34] <generic_nick|2> pcw_home: got a question for ya. i have a 7i48 on the way, and some pacific scientific digital servo drives. the servo has a resolver that goes to the servo drive and the drive converts it to a quadrature signal that in turn goes to the 7i48. will i have any issues with the 7i48 and this setup since the 7i48 will not be supplying the power for the encoder? i just dont want to fry anything again.
[11:36:35] <pcw_home> (pin or parameter)
[11:36:36] <cpresser> WalterN: yes. some materials are transparent for some wavelengths. glass for example is transparent for visible light, but not for far infrared
[11:37:13] <cpresser> pcw_home: true. i was mor thinking of 'net <netname> <inputpin> <outpin1> <outpin2> ...'
[11:37:31] <WalterN> cpresser: how about for the context of metals?
[11:37:37] <WalterN> and plastics
[11:37:44] <generic_nick|2> pcw_home: also, is polarity for the encoder inputs important?
[11:37:59] <cpresser> WalterN: acrylic is transparent for visible, but not for IR
[11:38:07] <pcw_home> generic_nick|2: you should not have an issue but make sure the drives and PC have a common ground
[11:38:18] <cpresser> metals also have quite different properties.
[11:38:37] <cpresser> i thinkt the mirrors in my co2-laser are made of metal
[11:38:55] <pcw_home> yes changing polarity of a +/- pair will reverse the encoder direction
[11:39:12] <generic_nick|2> right, but i meant in regards to cooking the 7i48
[11:39:13] <WalterN> cpresser: so mostly its a question to if the material is transparent to the wavelength used?
[11:39:47] <cpresser> WalterN: better: the inverse question: will it absorb the light.
[11:39:47] <IchGuckLive> hi all B)
[11:40:29] <cpresser> all incoming light is either: aborbed, refracted or passes the material
[11:40:35] <WalterN> cpresser: and if it does not? can I cover it with a thin layer of something that will?
[11:40:49] <cpresser> nope, then you will just cut your thin layer
[11:42:01] <IchGuckLive> pcb on laser ß
[11:42:16] <IchGuckLive> WalterN: ?
[11:42:22] <WalterN> ..?
[11:42:43] <IchGuckLive> thin layer absorb thinking of cutting pcb on laser
[11:43:25] <WalterN> well, when I got my diode laser for doing this stuff with, I didnt think about different wavelengths being able to do different things
[11:43:44] <IchGuckLive> B)
[11:43:44] <cpresser> WalterN: ist the laser visible?
[11:44:01] <WalterN> CO2 lasers are something like 1,500nm, diode laser is 810nm
[11:44:12] <generic_nick|2> pcw_home: is the /ENCA terminal generally for A+ or A-?
[11:44:26] <pcw_home> A-
[11:44:32] <ssi> / means not, so it's your low pin
[11:44:38] <cpresser> WalterN: CO2-Lasers are around 10µm.
[11:45:08] <WalterN> 1,000nm?
[11:45:12] <ssi> 10,000
[11:45:18] <WalterN> (derp)
[11:45:20] <ssi> :)
[11:45:34] <WalterN> 10,000? I thought they were a lot shorter
[11:45:42] <WalterN> mid-ranged IR
[11:45:45] * WalterN google
[11:45:50] <WalterN> *googles
[11:45:58] <ssi> wiki sez: The CO2 laser produces a beam of infrared light with the principal wavelength bands centering around 9.4 and 10.6 micrometers.
[11:45:59] <generic_nick|2> awesome, thanks. yea, believe it or not, i am not an electical engineer :D
[11:46:17] <ssi> ie ~10µm = 10,000nm
[11:46:40] <IchGuckLive> generic_nick|2: only pcw is
[11:46:52] <Jymmm> and SWPadnos
[11:47:05] <generic_nick|2> ssi: power supply works great, machine is running now
[11:47:06] <WalterN> oh I guess
[11:47:07] <WalterN> lol
[11:47:28] <WalterN> anyway, when I got my diode laser, I didnt think about wavelength differences
[11:47:48] <generic_nick|2> just waiting on the 7i48 so i can swap the 7i33 out for it and work on the 4th axis
[11:48:07] <WalterN> 'focus a bunch of power on one spot and its all good'
[11:48:13] <cpresser> WalterN: basically you should be able to work with material which are not transparent for visible light
[11:49:23] <WalterN> https://upload.wikimedia.org/wikipedia/commons/4/48/Commercial_laser_lines.svg
[11:49:55] <ssi> generic_nick|2: excellent :)
[11:50:24] <WalterN> interesting... its lacking diode lasers
[11:51:01] <cpresser> WalterN: i see InGaAs or GaAlAs
[11:51:03] <WalterN> or at least, the 810nm ones
[11:51:37] <cpresser> those are all semiconductor laser types
[11:51:57] <WalterN> yeah
[11:52:10] <WalterN> I dont see the 810nm one though
[11:53:08] <WalterN> oh, 810nm is barely visible too... evidently its close enough to red that I can faintly see some of the beam
[11:53:22] <cpresser> WalterN: its within the GaAlAs block?
[11:53:40] <WalterN> most charts end red at 700-750nm
[11:53:59] <WalterN> cpresser: no idea?
[11:54:36] <cpresser> idea for what exactly?
[11:55:03] <WalterN> cpresser: all I know is that most lasers sold as 'diode lasers' operate at 808nm
[11:55:42] <WalterN> (like mine)
[11:55:43] <cpresser> WalterN: the emitters in laserpointer device are also diode lasers
[11:55:58] <cpresser> and they are visible (red & green are common)
[11:56:29] <WalterN> but they are not sold with that advertisement?
[11:56:36] <WalterN> I donno
[11:56:40] <cpresser> 'diode' just tells the basic princible of physics
[11:56:49] <WalterN> right
[11:56:55] <cpresser> because its 'advertisement' :D
[11:57:13] <cpresser> they never tell the interesing facts, only the ones that may make it sell better
[11:57:47] <WalterN> *shrug*
[11:58:40] <WalterN> *cough* (lol)
[11:59:29] <WalterN> anyway
[12:05:12] <WalterN> I do kinda want to know what they are made of though
[12:05:16] <WalterN> now
[12:05:25] <WalterN> hmm
[12:07:00] <ssi> I wish I had lasers!
[12:07:13] <jdh> then you could charge them.
[12:07:23] <ssi> IM FIRIN MAH LASER
[12:11:29] <generic_nick|2> http://www.youtube.com/watch?v=h_iJe436esA
[12:11:31] <Tecan> (h_iJe436esA) "Shizuoka running on emc2" by "jeepinSD" is "Comedy" - Length: 0:00:51
[12:12:28] <ssi> nick, looks great
[12:12:47] <generic_nick|2> thanks
[12:13:05] <ssi> that's a nice machine
[12:13:08] <ssi> I want to get something like that
[12:13:12] <ssi> something that is cheap cause it needs a retrofit
[12:13:16] <ssi> like my hnc was
[12:13:23] <generic_nick|2> thanks, it's a shizuoka an-s
[12:13:43] <generic_nick|2> has a ATC on it
[12:14:19] <ssi> very nice
[12:14:22] <generic_nick|2> when i got it it was running a bandit I and steppers
[12:14:31] <ssi> poor thing :D
[12:14:36] <generic_nick|2> i know...
[12:14:36] <ssi> what's the spindle on it?
[12:14:37] <ssi> CAT?
[12:14:43] <generic_nick|2> nmbt40
[12:14:54] <ssi> what type of motor?
[12:15:00] <generic_nick|2> 3hp ac
[12:15:14] <generic_nick|2> 3 phase, running on a vfd
[12:15:17] <ssi> gotcha
[12:15:21] <ssi> single gearing?
[12:16:19] <generic_nick|2> it still has low gear but i have never used it. i replaced the varidrive setup with v belts and pulleys. it's set up to run 6k rpm
[12:16:28] <ssi> gotcha
[12:16:32] <generic_nick|2> i run the motor up to 120hz
[12:16:46] <ssi> the bearings will be happy at 6k?
[12:16:48] <generic_nick|2> it was spinning 6k in the video
[12:16:54] <generic_nick|2> probably not lol
[12:16:57] <L84Supper> the spindle was wobbling around all over :)
[12:16:57] <ssi> :D
[12:17:52] <generic_nick|2> dont care, spindle bearings are only $500, and i save way more than that by being able to cut nearly twice as fast.
[12:18:11] <ssi> well when you burn them up
[12:18:15] <ssi> put some in that'll handle it
[12:18:32] <generic_nick|2> so far they're fine, i've been running it at 6k rpm all day for 3 years now
[12:18:50] <ssi> does the headstock get warm?\
[12:18:52] <generic_nick|2> and they're the original spindle bearings from 1984 i would assume
[12:18:56] <generic_nick|2> nope
[12:19:05] <ssi> carry on then I suppose :D
[12:19:12] <generic_nick|2> lol
[12:19:16] <ssi> measured the runout?
[12:19:26] <generic_nick|2> i have a spare spindle anyways
[12:19:42] <generic_nick|2> no measurable slop in the spindle so far
[12:20:22] <ssi> what do those machines cost on the open market?
[12:20:40] <generic_nick|2> probably 1k or so
[12:20:51] <ssi> I need to find me one
[12:21:01] <ssi> I paid 1k for my HNC :D
[12:21:11] <ssi> plus $1k to fetch it
[12:21:11] <generic_nick|2> same here, it was barely used too
[12:21:14] <ssi> and $5k in tooling
[12:21:14] <ssi> hahaha
[12:21:21] <generic_nick|2> haha
[12:21:27] <ssi> maybe not quite that much
[12:21:36] <generic_nick|2> tooling always costs more than the machine when it comes to hardinge
[12:21:47] <ssi> I think all total with transport and tooling and mesa hardware my whole conversion was about $4500
[12:21:47] <generic_nick|2> mine came with the toolholders fortunately
[12:21:51] <ssi> but i've spent some on tooling since then
[12:21:56] <generic_nick|2> not bad
[12:22:04] <ssi> the guy I bought the lathe from had a ton of tooling,but he charged me for it all a la carte
[12:22:10] <generic_nick|2> i got mine 10 miles away
[12:22:15] <ssi> I got mine in connecticut :P
[12:22:19] <ssi> NOT 10 miles away
[12:22:24] <generic_nick|2> ha
[12:22:43] <ssi> I dragged a trailer from atlanta to connecticut
[12:22:48] <ssi> loaded it on the trailer in the snow with a come along
[12:22:53] <generic_nick|2> i got mine from a machinery dealer. brought it home in the back of a uhaul van and unloaded it with the lift gate lol
[12:22:59] <ssi> and when I got home
[12:23:02] <ssi> I bought a forklift to unload it
[12:23:07] <ssi> now I have a forklift :D
[12:23:10] <generic_nick|2> nice
[12:23:28] <ssi> I bought my surface grinder a couple years back, and the guy loaded it for me with a forklift
[12:23:28] <generic_nick|2> i just drug mine around by hand
[12:23:31] <ssi> when I got it home, I had no way to get it off the trailer
[12:23:35] <generic_nick|2> haha
[12:23:36] <ssi> so I ended up renting a lift
[12:23:39] <ssi> cost me almost $600
[12:23:43] <generic_nick|2> damn!
[12:23:49] <ssi> so when I got the hnc, I said screw that, and boughta $2500 truck
[12:24:03] <ssi> so naturally I need to buy more machines to justify the truck ;)
[12:24:05] <generic_nick|2> i unloaded my surface grinder with a engine hoist
[12:24:17] <ssi> I dunno where the hell I'd put a mill that size though
[12:24:23] <ssi> I need to sell my clausing 12x36
[12:24:29] <generic_nick|2> it's 7000lbs
[12:24:41] <jdh> I'll trade you my Clisby lathe for it
[12:25:14] <generic_nick|2> i need to find a new manual lathe. something with a big swing and short bed
[12:25:21] <ssi> jdh: yea? whassat?
[12:25:23] <ssi> tiny lathe?
[12:25:25] <ssi> that's what google suggests :)
[12:25:31] <jdh> yep
[12:26:02] <ssi> haha that certainly would help me free up shop space :P
[12:26:46] <ssi> my clausing is pretty worn out
[12:26:54] <ssi> it was the first machine I bought
[12:30:40] * frallzor is bored
[12:32:19] <ssi> me too
[12:36:02] <WalterN> oh... I need to get a 3-jaw chuck for a lathe too
[12:36:35] <WalterN> the quick release D type.. or whatever its called
[12:37:41] <WalterN> the one thats on the lathe now does not go on straight
[12:37:47] <WalterN> (manual lathe)
[12:45:04] <syyl> camlock?
[12:59:50] <FinboySlick> Does anyone make a relatively cheap equivalent to these: http://kerigroup.en.made-in-china.com/product/deumsznGhqVl/China-1-5KW-Water-Cooling-Spindle-Motor-and-Matching-Inverter-RKS1500-.html but with a drawbar mechanism? (I imagine it would be pretty complicated but I'm curious.)
[13:11:49] <WalterN> syyl: I guess? I dont really remember what they are called
[13:25:03] <DJ9DJ> namd
[13:27:52] <frallzor> FinboySlick that is the cheap alternative =)
[13:28:10] <frallzor> with drawbar = $$$$$$$
[13:29:30] <FinboySlick> frallzor: Yeah, I figured. You probably just can't do a drawbar system that'll run true at those RPM without spending a lot of time/money.
[13:30:15] <frallzor> Ive seen those that do cost alot of cash, yet not crazy much
[13:42:18] <andypugh> FinboySlick: If you keep the diameter of the moving parts small, I don't see any reason to expect it to go out of balance.
[13:42:49] <andypugh> All the moving parts of my drawbar fit down the original manual drabar hole.
[13:42:57] <FinboySlick> andypugh: Most of these spindles only expose one end of the shaft and aren't hollow though.
[13:43:17] <andypugh> That complicates things.
[13:43:41] <andypugh> Some of the Chinese spindles have a pneumatic drawbar built-in
[13:44:12] <FinboySlick> andypugh: That was sort of my original question.
[13:44:33] <gammax-Laptop> afternoon all
[13:48:59] <andypugh> FinboySlick: http://www.aliexpress.com/item/24000RPM-Milling-ATC-Spindle-Motor-BT30-4-5kw/538597386.html
[13:49:18] <andypugh> (If it is BT30 it has to have a drawbar..)
[13:50:05] <FinboySlick> andypugh: Not sure how crappy it is, bit it seems like a good price.
[13:50:23] <andypugh> There are more expensive ones, I rather chose the cheapest.
[13:52:45] <skunkworks> https://www.youtube.com/watch?v=iy1Mb6G_VJ0
[13:56:27] <FinboySlick> skunkworks: That's a pretty awesome machine.
[13:56:56] <skunkworks> it isn't mine. just a random video I found
[13:57:16] <FinboySlick> Looks sort of home-built.
[14:04:44] <L84Supper> if you guys find suppliers in the Nanjing, Suzhou, Shanghai, Hangzhou area I can stop by and check them out for you
[14:05:28] <L84Supper> Henan is o the way up to Beijing
[14:13:39] <automata> hi mharbler
[15:32:30] <largecheesepuff> Is there a easy way to disable tool change prompt?
[15:33:12] <mrsun> stop chaning tool ? :P
[15:44:45] <largecheesepuff> :-(
[15:45:08] <frallzor> pretty sure ive seen a way to disable it in the software
[15:45:27] <largecheesepuff> yeah I was just looking for some info...
[15:45:44] <frallzor> or maybe in a configfile or something
[15:46:53] <andypugh> largecheesepuff: What do you want to happen when the G-code specifies a tool change?
[15:49:07] <frallzor> nothing I´d say
[15:49:22] <frallzor> either he doesnt change tool, or he just want it to happen
[16:01:22] <largecheesepuff> andypugh: if I issue a T3 M6 G43 it just prompt me to change to tool and just changes the offset
[16:01:36] <largecheesepuff> it's gang tooled lathe
[16:12:31] <DJ9DJ> gn8
[16:32:44] <chopper79> I have a random issue I keep having on my personal machine. The issue is I can run the same piece of code 4-5 times(random numbers) with no issue and then lets say on the six one the Y and Z will remian doing what they commanded to do, but the X axis will randommly just start cutting a straight line. Then I will shut LinuxCNC down and restart it and cut a coupel more sheets and then the problem comes back. This will happen no matter if I am cutting at 10
[16:34:27] <cpresser> chopper79: you should try to debug this with halscope
[16:34:42] <cpresser> eg take a look at x-commanded-position and x-pos-feedback
[16:40:19] <chopper79> cpresser: Ok, would I be looking for something certain or just monitoring the command and feedback?
[17:02:33] <cpresser> chopper79: most likely they are the same (elese you would get an error). you could also monitor steh stepgens (or encoders, pid-output, ...) for that axis
[17:39:39] <SWPLinux> Jymmm: you around?
[18:02:06] <Jymmm> SWPLinux: yep
[18:02:55] <SWPLinux> Jymmm: me too
[18:03:00] <SWPLinux> got dinner plans?
[18:03:19] <Jymmm> SWPLinux: Just with you baby!
[18:03:36] <SWPLinux> I don't have a baby
[18:03:45] <SWPLinux> but my wife is here too, so maybe she qualifies :)
[18:04:01] <Jymmm> Ah, cool. Same place?
[18:04:03] <SWPLinux> is there a back seat in your truck?
[18:04:14] <Jymmm> Yep
[18:04:17] <SWPLinux> Palace BBQ, Oh yeah
[18:04:29] <SWPLinux> cool. I'll scrunch in there so she doesn't complain
[18:04:54] <Jymmm> scrunch? IT's a full aized SUV, not a tuna can
[18:04:56] <SWPLinux> I was bummed - the Moroccan place I went to the last couple of years has closed.
[18:05:01] <SWPLinux> even better
[18:05:04] <Jymmm> SWPLinux: seats 5 comfortably
[18:05:25] <SWPLinux> how smoky is it these days? (I know you were trying to quit, congrats)
[18:05:39] <SWPLinux> (Sharon is pretty sensitive to smoke, that's why I ask)
[18:06:23] <Jymmm> SWPLinux: Not that much
[18:07:00] <Jymmm> I can toss a trash can back there =)
[18:07:00] <SWPLinux> cool. I think we'll want to eat early-ish, how about you?
[18:07:02] <SWPLinux> heh
[18:07:15] <Jymmm> is 4 now, when?
[18:08:13] <SWPLinux> Probably no later than 5:30 or so, or at least leave by then
[18:08:37] <Jymmm> SWPLinux: Ok, I need to get gas.
[18:08:45] <Jymmm> SWPLinux: When did you get into town?
[18:08:54] <SWPLinux> wouldn't the Korean food give you gas?
[18:09:29] <SWPLinux> I got in late Sunday night. I've just been really busy into the evenings, when I get tired due to the time change
[18:09:39] <Jymmm> ah
[18:09:50] <Jymmm> you leave tomorrow?
[18:09:58] <SWPLinux> nope, wer
[18:10:02] <SWPLinux> ugh
[18:10:14] <SWPLinux> we're staying an extra day, leaving (from SFO) on Saturday
[18:10:22] <Jymmm> Ah, ok
[18:10:37] <Jymmm> SWPLinux: Do I know where you are?
[18:11:31] <SWPLinux> yes, you do. Same hotel, different room (Hilton, 300 Almaden)
[18:11:31] <Jymmm> =)
[18:12:04] <Jymmm> SWPLinux: room?
[18:12:40] <SWPLinux> 826
[18:13:40] <Jymmm> Okey, let me get moving or I'll never get there =)
[18:14:02] <SWPLinux> I need to see where Sharon is - I think she went to an art museum nearby
[18:55:08] <SWPLinux> Jymmm: How about now? Sharon just got back, and she'll probably be hungry by the time we get to the restaurant
[18:55:44] <Tom_itx> sounds good. we'll all meet you there
[19:07:07] <andypugh> largecheesepuff: For gang tooling, you could just skip M6 and just use the G43.
[19:08:01] <GammaX> hello hellooo
[19:08:12] <Tom_itx> does lcnc have a tool prefetch M or G code?
[19:08:38] <andypugh> But if you have a safe-retract position programmed (and M6 is programmed to go there) then I think you can just net tool-change-request to tool-changed in HAL with no toolchange logic involved and it should be fine. (ie, just take out everything related to hal_manualtoolchange)
[19:08:51] <GammaX> andypugh you mentioned gang tooling... Do you know anything about the anilam lathemate?
[19:08:54] <andypugh> Tom_itx: T can do that.
[19:09:18] <andypugh> GammaX: Not a thing :-)
[19:09:23] <GammaX> damn,
[19:09:57] <Tom_itx> ahh i see... M6 actually initiates the change
[19:10:07] <GammaX> Gotta find someone with that dang machine...
[19:10:22] <andypugh> Tom_itx: ie, if you TN M6 on one line, then TN on the next line, the Hal pins wiggle in such a way as to allow the changer to locate the next tool, then change to it on the _next_ M6.
[19:10:47] <Tom_itx> in some cases it may be quite a few lines before
[19:10:54] <Tom_itx> ie large belt driven changers
[19:11:31] <andypugh> GammaX: After googling, I have seen them before. Like a clamp-on set of CNC slides for a conventional lathe?
[19:11:58] <andypugh> Tom_itx: Yes, you can have the _next_ T after each M6.
[19:12:00] <GammaX> in a tbar for a mill or gang tool setup... how much of a difference should there be between the inner diameter of the post and the hole... that make sense?
[19:12:13] <GammaX> andypugh yes!
[19:12:39] <andypugh> Always seemed quite a neat idea.
[19:13:17] <andypugh> There was a tiny second-op Hardinge with a very similar device on it on eBay the other day.
[19:13:33] <GammaX> andypugh have alink? :D
[19:20:03] <andypugh> GammaX: Ah, not eBay: http://www.go-dove.com/en/event-17197/lot-3001/Servo-Products-Hardinge-M-8001-CNC-Mini-Lathe
[19:20:36] <GammaX> thats is very awkward lol
[19:21:10] <GammaX> and nothing like myne. I have a hardinge hc converter over to a cnc, has 2 tables mounted to another table on the mill.
[19:21:35] <GammaX> If only I could think of a way to start bringin in money with that and my mill...
[19:23:15] <Tom_itx> make stuff and sell it :)
[19:23:29] <GammaX> thats the hard part...
[19:23:34] <GammaX> what do I MAKE?! lol
[19:23:43] <Tom_itx> if i told you then i couldn't do it
[19:23:57] <Tom_itx> what ever happened to danimal?
[19:24:26] <GammaX> Tom_itx what sector do you thinkg, would be best to get into?
[19:24:37] <Tom_itx> no idea
[19:24:44] <Tom_itx> depends on your locale
[19:24:53] <GammaX> denver co!
[19:25:00] <Tom_itx> crack pipes
[19:25:07] <Tom_itx> :)
[19:25:09] <GammaX> this is plausible..
[19:25:28] <Tom_itx> there is more drug traffic from there thru here than you can believe
[19:26:36] <GammaX> Well I cant make glass items BUT I can deff make crack spoons
[19:26:47] <Tom_itx> they set up drug checks along the highway for that
[19:26:57] <andypugh> Where was Danimal based? His web site still looks live: http://www.homebrewedcomponents.com/store.php
[19:27:06] <Tom_itx> andy, californ i a
[19:27:24] <Tom_itx> he was so active for a while then just dissappeared
[19:27:35] <Tom_itx> i suppose that's just irc
[19:28:13] <andypugh> Though I never worked out why he was so active, as all his LinuxCNC stuff was fully functional and making money, and he wasn't involved in development.
[19:28:14] <Tom_itx> GammaX, he was making specialty bike sprockets etc
[19:28:32] <Tom_itx> i'm not involved in developement either
[19:28:51] <Tom_itx> are you planning the long trip to the fest?
[19:28:57] <Tom_itx> in june
[19:29:22] <Tom_itx> that would be a stretch for you i suppose
[19:29:34] <andypugh> Who me?
[19:29:38] <Tom_itx> yes
[19:29:45] <andypugh> Already bought the airline ticket.
[19:29:50] <Tom_itx> really??
[19:29:53] <Tom_itx> cool
[19:29:54] <andypugh> Aye
[19:29:59] <Tom_itx> it's in my home town
[19:30:20] <andypugh> I couldn't see the tickets getting any cheaper.
[19:30:28] <Tom_itx> no they never get cheaper
[19:30:34] <Tom_itx> unless you book standby
[19:30:57] <Tom_itx> were you at the last one?
[19:31:23] <andypugh> No, I have only ever met one other LinuxCNC user.
[19:31:43] <Tom_itx> i'm gonna try to drop by for part of a day at least
[19:31:59] <Tom_itx> i won't have alot to contribute but i thought it would be fun
[19:33:24] <Tom_itx> i've been by Stuart's place many times but never been inside
[19:33:29] <SWPLinux> it
[19:33:38] <SWPLinux> it's smoky, but has lots of machinery
[19:33:42] <SWPLinux> (Stuart's place)
[19:33:50] <Tom_itx> smoke from machines?
[19:33:53] <andypugh> Smoky?
[19:33:59] <SWPLinux> no, from cigarettes
[19:34:01] <Tom_itx> ahh
[19:34:08] <toastyde1th> Oi, what's best lightweight/solid small lathe, in the (12-16)x40 ran ge
[19:34:10] <andypugh> Is that still legal in the US
[19:34:19] <toastyde1th> ideally under 1k lbs
[19:34:30] <Tom_itx> not in public buildings
[19:34:33] <SWPLinux> yep. they have a sign on the front door that says that smoking is permitted on the premesis
[19:34:39] <andypugh> toastyde1th Get something made in the 1970s or earlier.
[19:34:55] <toastyde1th> andypugh, the problem is i'm sorting based on weight here
[19:35:08] <toastyde1th> there are a lot of very heavy small lathes (i know a good amount about heavy shit)
[19:35:29] <toastyde1th> I was hoping someone had a few specific models off the top of their head
[19:35:51] <Tom_itx> you're working on the ship machine shop right?
[19:35:58] <toastyde1th> yeah
[19:36:23] <toastyde1th> there are a few good mills in the thousand pound range, looking around at lathes
[19:37:00] <andypugh> Ah., well, for onboard a ship you need: http://www.lathes.co.uk/adcock&shipleycombination/index.html
[19:37:33] <toastyde1th> haha that probably weighs 10 tons
[19:37:44] <Tom_itx> the titanic probably had one
[19:37:51] <andypugh> Designed for use in boats though.
[19:38:44] <andypugh> Harrison M250 is a fairly compact proper lathe, and 785lbs
[19:38:44] <toastyde1th> it's desined to go into ships
[19:38:51] <toastyde1th> 3000gwt or larger
[19:39:48] <toastyde1th> will look up the harrison ,ty
[19:39:57] <andypugh> Here is the next size up (not a lot heavier) http://www.ebay.com/itm/13-19-x-25-Harrison-Model-M300-Engine-Lathe-/321039246777?pt=LH_DefaultDomain_0&hash=item4abf6e25b9
[19:40:17] <toastyde1th> twice as heavy
[19:40:55] <andypugh> Ah, yes, so it is.
[19:41:13] <toastyde1th> 800 lbs is a good weight
[19:51:51] <Tom_itx> how big a chuck?
[19:54:15] <r00t4rd3d> wood a woodchuck chuck
[19:55:13] <r00t4rd3d> if a woodchuck could chuck wood
[19:57:35] <Tom_itx> seems they go from ~300lb to 1500lb
[19:57:44] <Tom_itx> or more
[19:58:40] <toastyde1th> Tom_itx, was that to me?
[19:58:46] <Tom_itx> yes
[19:59:08] <r00t4rd3d> lol
[19:59:12] <toastyde1th> probably a couple small ones, like an 8-10" manual 3 jaw, a faceplate, and a 4 jaw at the max swing size
[19:59:17] <Tom_L> shipping weight 1154: http://www.northerntool.com/shop/tools/product_40810_40810
[19:59:43] <toastyde1th> bench lathe is probably the way to go, save space
[20:00:58] <toastyde1th> i'd rather have more weight on the lathe than mill anyway
[20:01:16] <Tom_itx> i thought you found a mill but was a tad over your weight
[20:01:23] <toastyde1th> found one that was under
[20:01:25] <toastyde1th> 700 lbs
[20:01:28] <Tom_itx> oh
[20:02:13] <toastyde1th> I can drill and bore on a larger lathe
[20:02:18] <toastyde1th> far more gear
[20:02:25] <toastyde1th> not too much to mill
[20:09:15] <Tom_L> 1015lb http://www.travers.com/87-115-230?Category=UserSearch=lathe||UserSearch=block%20id%2036135%20and%20class%20level3%20id%20298725
[21:00:09] <skunkworks> we just need to get alex over here
[21:14:25] <kizer> really.
[21:14:31] <kizer> linux for machinists
[21:14:41] <kizer> thats better than crack
[21:16:01] <kizer> i'd like to get it to run within crunchbang
[21:19:15] <kizer> i am browsing the site and can't see where the source code is and that is probably because i have consumed too much caffeine
[21:23:02] <Tom_itx> http://git.linuxcnc.org/gitweb
[21:29:41] <kizer> thank you
[21:29:49] <kizer> how does it run on pi?
[21:32:35] <kizer> ah i found info on that
[21:32:39] <kizer> well, this is awesome
[21:32:51] <kizer> another project to confuse the fk out of me until i understand
[22:51:14] <generic_nick|2> http://farm9.staticflickr.com/8266/8682778256_d6a63a13f0_b.jpg
[22:51:38] <kizer> generic_nick|2: cool
[22:51:45] <kizer> what did you use to make it?
[22:52:36] <generic_nick|2> thanks. http://farm9.staticflickr.com/8383/8681666143_649c95a711_b.jpg
[22:52:44] <generic_nick|2> my shizuoka mill
[22:53:02] <kizer> and what program
[22:53:03] <generic_nick|2> new product ill be making for another company.
[22:53:12] <generic_nick|2> masterscam
[22:53:25] <kizer> scam? is that a mispelling
[22:53:37] <Tom_itx> ja
[22:53:59] <generic_nick|2> i didnt design it
[22:54:04] <kizer> okay i get it. well i can only wonder if linuxcnc is comparable to mastercam
[22:54:04] <generic_nick|2> i just machine it
[22:54:21] <Tom_itx> it depends on their post
[22:54:31] <Tom_itx> i wrote one for my smartcam for linuxcnc
[22:55:03] <Tom_itx> generic_nick|2, you didn't draw it?
[22:55:08] <generic_nick|2> no
[22:55:46] <generic_nick|2> i helped him design it so that i can machine it efficiently, but he did all the modeling
[22:57:43] <generic_nick|2> i gotta make about 1000 of those a month
[22:58:22] <generic_nick|2> crossing my fingers that my mill lasts a couple months so i can buy a new one.
[22:58:28] <gammax-Laptop> 1000 of what? I came in late?
[22:58:35] <generic_nick|2> http://farm9.staticflickr.com/8383/8681666143_649c95a711_b.jpg
[22:58:48] <generic_nick|2> cnc machined trucks
[22:59:05] <gammax-Laptop> oh nice
[22:59:09] <generic_nick|2> thanks
[22:59:10] <gammax-Laptop> myust be a decent contrac
[22:59:31] <generic_nick|2> yea should be decent
[22:59:51] <kizer> generic_nick|2: do you have an angle on the axles?
[23:00:03] <gammax-Laptop> generic_nick|2, if you dont mind me asking, how did you get the contrsact? im in the phase of aquiring work...
[23:00:15] <generic_nick|2> angle?
[23:00:19] <kizer> like camber
[23:00:33] <generic_nick|2> there's no camber
[23:00:40] <kizer> just an illusion k
[23:01:08] <generic_nick|2> GammaX: ive been doing some random work for him for a few years. he just asked me if i wanted to make these
[23:01:22] <generic_nick|2> i met him through the guy who does my waterjetting
[23:01:44] <gammax-Laptop> nice!
[23:02:39] <generic_nick|2> takes me about 15 minutes for the hanger and base. i think i can cut the program down to 10-12 minutes for both
[23:02:56] <gammax-Laptop> generic_nick|2, what kinda mill you got?
[23:03:07] <generic_nick|2> shizuoka an-s
[23:03:26] <gammax-Laptop> never heard of it but im assuming its faster than my 45rf! lol
[23:03:35] <generic_nick|2> big knee mill with a toolchanger
[23:03:39] <gammax-Laptop> rf45*?
[23:03:50] <generic_nick|2> weighs about 7000lbs i think

[23:05:44] <generic_nick|2> san diego ca
[23:06:18] <gammax-Laptop> ah nice
[23:06:28] <gammax-Laptop> anyone in here from denver area?
[23:06:29] <generic_nick|2> u?
[23:06:48] <gammax-Laptop> besides me? lol
[23:19:25] <t12> how do you handle the work flips
[23:34:08] <gammax-Laptop> anyone recomend my next cnc mill? i need some ideas to move past the rf45.....
[23:48:55] <generic_nick|2> bridgeport, shizuoka, etc
[23:50:11] <generic_nick|2> t12: were you talking to me? multiple fixtures and a 4th axis
[23:53:45] <t12> yeah
[23:53:46] <t12> ahh ok
