[00:01:50] <[cube]> ok got the lathe inside and bunch of weight off it
[00:01:52] <[cube]> tmrw have to get it down the stairs
[00:01:56] <[cube]> http://imgur.com/a/SeRdr
[00:03:13] <Jymmm> flattened large cardboard box and some rope
[00:03:25] <[cube]> hmmm
[00:03:46] <[cube]> not a bad idea
[00:04:04] <Jymmm> and two boxes slide nicely on top of each other
[00:04:04] <[cube]> was thinking of bolt it down to two 2x4s
[00:04:06] <[cube]> like 'skis'
[00:04:22] <[cube]> hm
[00:04:23] <Jymmm> but you have carpet, so no need for the 2nd box
[00:04:49] <[cube]> i feel like it would crush right through the box
[00:04:58] <Jymmm> I always carry two flat boxes in the back of the suv, makes loading heavy stff easy
[00:05:16] <[cube]> the reason i say that, is it 'fell' through the plywood crate it came in
[00:05:16] <Jymmm> ok, playwood then cardboard
[00:05:18] <[cube]> while movie it
[00:05:21] <[cube]> *moving
[00:05:53] <[cube]> yeah cardboards not a bad idea
[00:06:02] <[cube]> i have some sheets of masonite too
[00:06:24] <Jymmm> and the weigth.... you'll need a couple of bodies to stop it from flying down the stairs
[00:06:32] <[cube]> yea
[00:06:47] <[cube]> also not afraid of screwing a pullet into the floor
[00:06:49] <[cube]> through the carpet
[00:06:52] <Jymmm> no masonite, just large carboard box, just enough friction
[00:06:55] <[cube]> in the corners, should be okay
[00:07:05] <[cube]> *pulley
[00:07:51] <Jymmm> do you have a carabiner?
[00:08:05] <[cube]> yep
[00:08:09] <[cube]> i have a come a long
[00:08:17] <[cube]> that i used to get it INside
[00:08:22] <[cube]> up a flight of 10 or so stairs
[00:08:27] <Jymmm> Then use a munter hitch or evena double munter hitch
[00:08:48] <Jymmm> climbing rated carabiner
[00:08:51] <Jymmm> locking
[00:09:00] <[cube]> the come a long has straps that should work
[00:09:21] <[cube]> i guess i'll just reverse the process of getting it up stairs
[00:09:49] <[cube]> http://thumbs2.ebaystatic.com/d/l225/m/m2zmSS4IrN7-7uSWvKErKuQ.jpg
[00:10:15] <[cube]> also have a winch....
[00:10:53] <Jymmm> but do you have enough hands to control all that and prevent the lathe from going sideways? lol
[00:11:15] <[cube]> heh I do not :)
[00:11:19] <Jymmm> https://www.youtube.com/watch?v=TOf1Yzu_OS0
[00:11:23] <[cube]> i'll have to call in some favors, for sure
[00:11:42] <[cube]> hmm nice
[00:12:34] <Jymmm> https://www.youtube.com/watch?v=vUZbIi8XJjM
[00:12:36] <[cube]> i'd have to be pretty confident in the pivot point at the top of the stairs :)
[00:12:39] <Jymmm> another example
[00:12:51] <Jymmm> but you can do fine control
[00:13:10] <Jymmm> and just lock off the line if you need to pause
[00:13:29] <[cube]> yeah very cool
[00:13:31] <[cube]> thx
[00:14:01] <Jymmm> test before loading
[00:41:42] <norias> whoa
[00:55:21] <norias> The President of the United States of America announced today
[00:55:32] <norias> that he doesn't have to seek relection
[00:55:46] <norias> so he's just gonna do and say whatever he wants to.
[00:56:29] <norias> Deal with it, people.
[00:57:08] <witnit> Probably what needed done in the first place
[00:57:33] <norias> eh. Could be.
[00:59:27] <XXCoder> nothing more powerful than no reelection president
[00:59:35] <XXCoder> hope he does good.
[00:59:52] <norias> doubt it
[00:59:57] <witnit> not to be negative but consider the long lines at mcdonalds, people dont want to hear about dieting and eating healthy, even though its whats best
[00:59:58] <XXCoder> why?
[01:00:09] <norias> i think the best thing an end of term president can do
[01:00:16] <norias> is not screw too much stuff up
[01:00:31] <witnit> i dont think screwing things up is what he had in mind
[01:00:43] <norias> yeah... no one ever has it mind
[01:00:54] <norias> but it still seems to happen
[01:01:01] <witnit> being idle is the biggest screw up anyone can make
[01:01:13] <witnit> imo
[01:01:42] <XXCoder> tell that to congress
[01:01:48] <XXCoder> freaking CON gress
[01:01:49] <norias> hmmm
[01:01:52] <witnit> my point exactly
[01:01:54] <XXCoder> I want progress not congress
[01:02:09] <norias> what about sexual congress?
[01:02:20] <XXCoder> lol
[01:02:34] <norias> not that i'm offering
[01:02:36] <norias> just saying
[01:02:38] <norias> hey
[01:02:42] <norias> congress isn't always bad
[01:02:59] <XXCoder> yeah but current sure is
[01:03:12] <norias> i ...
[01:03:16] <norias> i don't honestly know
[01:03:24] <witnit> i can say the same
[01:03:27] <norias> i'm not even sure how to measure that
[01:03:27] <XXCoder> know what they did on first day?
[01:03:32] <XXCoder> try to deny women rights
[01:03:45] <norias> ok, this should be interesting
[01:03:47] <norias> how?
[01:03:55] <witnit> yes do tell hahaha
[01:04:11] <XXCoder> actually no. I dont like discussing political things.
[01:04:17] <witnit> understandable
[01:04:19] <XXCoder> im awful on that heh
[01:04:25] <witnit> this is not the place for it :)
[01:04:32] <norias> oh, it's not?
[01:04:34] <norias> sorry.
[01:04:42] <witnit> not really, even though i enjoy it
[01:04:52] <norias> i'll keep that in mind
[01:05:03] <witnit> i think most of the people in here would assume keep hot button topics to a minimum
[01:05:13] <witnit> like racial jokes, i love them but do not share so much :(
[01:05:24] <norias> this has been one of the best / most useful irc chans i've been on in a while
[01:05:31] <norias> so, i'd rather not be the bad guy
[01:05:38] <norias> at least not here
[01:05:55] <norias> :)
[01:06:21] <witnit> usually very straightforward help and lots of "congratulations on getting to that next point in your project" type stuff :)
[01:06:45] <unfy> some folks will do politics here. i tend to agree - it's not the place for it.
[01:06:49] <norias> right on
[01:07:35] <XXCoder> religion poticials and race
[01:07:40] <XXCoder> top 3 buttons
[01:07:56] <norias> no nascar?
[01:07:59] <norias> no f1?
[01:08:01] <witnit> I noticed there is a wonderful hierarchy of passing along support, for example if you know the answer to something you understand well, you really take the load off of the programmers which are working on the next aspect of the community
[01:11:11] <witnit> I recall coming in here asking about how to control floppy drives with stepconf and a year later buying the newest card mesa was putting out and flashing it with bitfiles, specifying encoders and doing pid tuning
[01:12:11] <witnit> never would have learned any of it without good direction from people like xxcoder, archivist, pcw, (its a much bigger list reallly)
[01:12:32] <XXCoder> just basics from me really lol
[01:13:20] <witnit> when you take the time out of your night to link somone the documentation that saved them 10+ hours of failure, its more meaningful than saying "just the basics" :)
[01:13:43] <XXCoder> thanks
[01:15:54] <norias> swell group of fellas
[01:17:43] <witnit> i need to get a video up of some of my linuxcnc machines, I have done 3 retrofits and repaired a 6 axis motoman robot, each machine doing me wonders at the shop to this day
[01:18:49] <Tecan> [cube] you get your printer working ?
[01:19:15] <norias> nice
[01:19:29] <norias> so, ok, honest question
[01:19:40] <norias> every system has it's downsides
[01:19:50] <norias> what are the downsides to linuxcnc
[01:19:58] <norias> i can't imagine emulating plc's etc
[01:20:03] <witnit> learn alot on your own, no true support system
[01:20:10] <norias> is better than or equal to real plc's
[01:20:15] <witnit> better
[01:20:16] <norias> etc
[01:20:27] <norias> how is it better?
[01:20:55] <witnit> i replaced my PLC with a $10 computer and a 10$ relay board and its boasting a cute lil website for monitoring and control
[01:21:09] <witnit> not to mention ondemand reprogramming remotely
[01:21:37] <norias> i'm going to have to think about this one for a bit
[01:21:37] <witnit> with encoder support.....
[01:21:44] <norias> i'm a little dubious
[01:21:47] <norias> that it could be better
[01:21:58] <norias> (depending on your definition of good, i guess)
[01:22:18] <witnit> what makes a plc good?
[01:22:22] <norias> but i could also be naive and uninformed
[01:23:01] <norias> i didn't say i had a good argument!
[01:23:18] <archivist> norias, there is classicladder built in to linuxcnc for the plc part of a machine
[01:23:22] <witnit> linuxcnc has built in ladder logic as well so you have that, cost is lower, and you can modify variables on the fly
[01:23:31] <norias> right, i get that
[01:23:44] <norias> but.. can the performance really be as good?
[01:23:54] <norias> emulating hardware in software?
[01:23:54] <archivist> you can also play with hal to do wonders
[01:24:04] <witnit> like, reliability?
[01:24:13] <norias> naw, just performance
[01:24:14] <archivist> a plc in software too!
[01:24:21] <norias> like line on life following
[01:24:22] <archivist> in/is
[01:24:25] <norias> guh
[01:24:27] <norias> line on line
[01:24:38] <norias> fair point, archivist
[01:24:48] <archivist> it is the same, not emulating
[01:25:07] <norias> hmm
[01:25:32] <norias> yeah, i got to think this one through
[01:25:51] <witnit> I dont want to break your argument, but i really dont think there is an advantage unless you are a big corporation and do not have the people to understand this technology since it is not a global standard
[01:26:13] <witnit> what are your requirments of the plc?
[01:26:24] <archivist> I have three machines under linuxcnc too, a 5 axis mill, a small lathe and a hobbing machine (geared axes)
[01:26:40] <norias> don't get me wrong
[01:26:46] <norias> i bet it's all sorts of awesome
[01:26:58] <norias> but my knowledge of the world
[01:27:06] <norias> indicates thre are always tradeoffs
[01:27:23] <norias> so i just wonder what the tradeoff is with linuxcnc
[01:27:41] <witnit> mine are , hardinge automatic lathe, index b60, and an automatic crossdrilling and deburing tool (yanked one of those junk micrologix things out and used my own relay board and printer port )
[01:27:42] <norias> because it seems to have a lot of great features
[01:28:00] <witnit> ;) :)
[01:28:03] <archivist> the fact it can do almost anything means a little more effort configuring
[01:28:17] <norias> so
[01:28:27] <norias> if i built most of the control logic with say
[01:28:32] <norias> ic's
[01:28:38] <norias> like a bunch of op amps
[01:28:41] <norias> and ...
[01:28:55] <norias> micropressors
[01:29:07] <norias> (i'm kinda tired and had to take pain meds, too)
[01:29:12] <archivist> no need for all that effort
[01:29:25] <archivist> dont re invent the wheel
[01:29:26] <norias> that's basically what the control was
[01:29:30] <norias> that i'm replacing
[01:29:50] <archivist> what does the machine do
[01:29:57] <norias> 3 axis mill
[01:30:17] <archivist> then should be simple to retrofit
[01:30:38] <norias> i'm totally convinced of that part
[01:30:52] <norias> and that's kind of my point
[01:30:56] <norias> i see a lot of benefits
[01:31:02] <norias> and i wonder what the tradeoffs are
[01:31:19] <witnit> but, you cant cnc with a plc
[01:31:25] <norias> maybe there aren't any
[01:31:39] <norias> maybe i'm missing something
[01:31:54] <archivist> witnit, you can, as long as the job is not too variable
[01:31:55] <norias> sometimes some technology is just simply superior
[01:32:37] <norias> but, i would think if that's the case...
[01:32:48] <norias> i should be able to crack open the controller on say
[01:32:49] <archivist> I used to repair a window machine which had a plc
[01:32:56] <norias> a top end DMG
[01:33:06] <norias> and just see a couple servo amps
[01:33:12] <norias> an i/o board
[01:33:17] <norias> and a pc
[01:34:03] <witnit> it sounds like you are about $300 away from a working cnc going this route providing all amps and encoders, switches are good
[01:34:13] <archivist> well replace software on the PC and then you may need a different io card (one compatible) then it should work
[01:34:34] * archivist has to go out now
[01:34:49] <witnit> build us wonderful things!
[01:41:49] <witnit> norias do you know kind of servos/amps/encoders it uses?
[01:42:43] <norias> yeah
[01:42:52] <norias> amps are... glentek ga370
[01:43:02] <norias> drives some brushed dc motors
[01:43:10] <witnit> wow, i built mine using that same rig
[01:43:11] <norias> i forget the encoders off hand
[01:43:19] <witnit> do you need any manuals?
[01:43:31] <norias> for the ga370?
[01:43:32] <witnit> i have them for the motors, boards and encoders i think
[01:43:34] <witnit> yeah
[01:43:41] <norias> i have that one
[01:43:51] <norias> i need to get the encoder one
[01:43:54] <norias> at some point
[01:44:04] <norias> what mesa boards did you use/
[01:44:24] <witnit> i ended up switching to a different amps after i did the initial build
[01:44:41] <witnit> i used the 7i33ta
[01:44:50] <norias> ahh, ok
[01:45:01] <norias> that's the daughter board i thought was right
[01:45:13] <norias> and it's like... uh 5i something
[01:45:15] <norias> for the pci
[01:45:18] <norias> right/
[01:45:23] <witnit> well at first
[01:45:29] <witnit> then i switched to a really low cost card
[01:45:32] <norias> (i have all that stuff on my work computer)
[01:45:37] <witnit> 7i90 and went throught eh printer port
[01:45:40] <norias> why the switch?
[01:45:52] <witnit> much cheaper and it was all i needed
[01:46:06] <witnit> add the 7i90 and the 7i33
[01:46:11] <norias> but you had already bought the more expensive one?
[01:46:29] <witnit> i wiped the board out by not grounding my machine :(
[01:46:35] <norias> oh
[01:47:06] <norias> you mean grounding the 3 phase?
[01:47:11] <witnit> 220 3phase
[01:47:15] <witnit> feedback through encoder
[01:47:23] <witnit> and got it
[01:47:29] <norias> oh
[01:47:48] <norias> well, the power supply stuff was done by an electrician
[01:47:49] <witnit> three phase for the motor on the spindle and dc for the servos
[01:47:51] <norias> for this machine
[01:47:58] <norias> so...
[01:48:12] <norias> i'm thinking that's probably right
[01:49:00] <norias> i'm a machinist who used to do some c coding
[01:49:03] <norias> and digs linux
[01:49:16] <norias> this electrical / electronics side of stuff
[01:49:20] <norias> is going to take me a minute
[01:50:09] <witnit> just get your old floppy drives out, push a couple wires into your printer port and start telling them to move :)
[01:50:25] <witnit> simple as that
[01:51:15] <norias> ahh, ok
[01:51:25] <norias> do i need to yell at them?
[01:51:29] <norias> or say it nice?
[01:51:37] <witnit> just make sure you tell the to G0
[01:51:45] <witnit> cnc joke^
[01:51:51] <norias> yeah, yeah
[01:52:06] <norias> boring mill
[01:52:09] <norias> blah blah
[01:56:28] <witnit> as a machinist, what kinds of machines did you run?
[02:00:37] <XXCoder> he left
[02:00:56] <witnit> ha yeah i noticed :P i wasnt paying attention
[02:00:57] <XXCoder> myself I ran ancient pmx, haas router, various models of hurco
[02:01:03] <witnit> oooh
[02:01:30] <witnit> i never ran any cnc's i was on manual until i built my own :)
[02:01:40] <XXCoder> nice
[02:01:54] <witnit> what was your favorite interface?
[02:02:03] <XXCoder> hurco
[02:02:08] <XXCoder> dunno what they call it
[02:02:17] <XXCoder> I has zero experence with linuxcnc
[02:03:14] <witnit> it must have been a pretty natural feeling design
[02:05:02] <witnit> i noticed some interfaces are very intimidating for a user
[02:05:27] <XXCoder> haas is intimidating a bit
[02:05:31] <XXCoder> it has strange design
[02:05:44] <XXCoder> hurco is simplier and has more direct buttons to do stuff
[02:05:54] <XXCoder> haas has more buttons but.. noit better there.
[02:06:05] <XXCoder> pmx is very old
[02:06:16] <XXCoder> strange stuff I just learned how to press start lol
[02:06:25] <witnit> heh
[02:06:44] <witnit> are currently doing a linuxcnc build?
[02:07:17] <XXCoder> well techinically
[02:07:24] <XXCoder> havent worked on it for a bit
[02:12:41] <witnit> im doing a complete rebuild of my crossdrilling machine, currently its on a printer port, i have a 7I92 coming so i can put the computer on the other side of the room, and later have the things i need to add a conveyer
[02:14:18] <XXCoder> cool. well time for me to sleep. nighht
[02:14:42] <witnit_> later
[02:31:40] <Deejay> moin
[02:32:46] <Jymmm> hey
[02:34:27] <unfy> o/
[02:36:58] <witnit> mojn!
[02:38:26] <Deejay> \o/
[02:43:51] <DGMurdockIII> Hi again
[02:44:13] <DGMurdockIII> Is linux cnc easy to use
[02:45:24] <unfy> i've not done too much with it, but it seems easy enough
[02:48:29] <Jymmm> DGMurdockIII: Make a LiveCd, try it yourself, read thru the manuals and see for yourself.
[02:48:54] <DGMurdockIII> Ok
[02:49:55] <DGMurdockIII> I now it dose not have a modeling program on it
[02:54:16] <Jymmm> PCW: Frys has Tenergy protected 8650 2600mAh on sale for $6 this week
[02:54:22] <Jymmm> 18650
[03:01:25] <witnit> awwee my router/firewall was up for months and I had to reboot it
[10:10:09] <_methods> http://secupwn.github.io/Android-IMSI-Catcher-Detector/
[10:10:27] <_methods> OT but cool
[11:13:44] <Sandblech_Micha> Hello. I have the Linuxcnc 2.6.5 from the Debian Live CD Installed. Working fine. How can i use the camview-emc in AXIS for my Webcam? I know the WIKI for this, but there is now hints for the DEBIAN Wheezy.
[11:23:51] <archivist> camview does not get a lot of love, you may need to work on it
[11:25:40] <Sandblech_Micha> Is there a alternative for a Video TAB in AXIS?
[11:26:09] <archivist> I am not aware of one
[11:26:53] <cradek> I think camview does not currently have a maintainer, and it shows
[11:27:00] <cradek> please let us know what you come up with
[11:27:13] <cradek> I see more questions than answers about it
[11:28:22] <zeeshan> lol
[11:29:26] <Sandblech_Micha> Maybe i try it in an older Version of Linuxcnc under Unbuntu with camview. I need only to drill PCBs.
[11:31:19] <Sandblech_Micha> This is what i like to use under Linux with the Webcam: https://www.youtube.com/watch?v=tzI445XsPDs
[11:33:06] <Sandblech_Micha> Ok thank you.. Bye
[12:08:58] <albova> hello
[12:11:06] <_methods> hallo
[12:12:05] <albova> is there anyone ?
[12:13:38] <archivist> plenty, just waiting for questions
[12:14:10] <albova> hi i only test this chat
[12:19:27] <zeeshan> lol
[12:20:10] * archivist puts 240 volts across zeeshan to test him
[12:20:18] <zeeshan> zzzzzzzzzzzt

[12:38:29] <tjtr33> to do this kinda work https://www.youtube.com/watch?v=uc8BUu61LvI
[12:54:25] * JT-Shop thinks he will miss his nap today... powder coating 50 parts
[12:55:09] <Tom_itx> aww
[12:55:48] <jdh> it's good to have stuff to do.
[12:56:08] <Tom_itx> 22F
[12:56:16] <JT-Shop> 27f here
[12:56:17] <Tom_itx> i think i'll go out and tan
[12:56:44] <Tom_itx> no, actually i'm gonna work on my control box
[12:56:54] <marmite> 1 calvin here
[12:57:31] <Tom_itx> JT-Shop, are you just baking powdercoat to stay warm?
[12:57:55] <JT-Shop> no, I need to get them done now that I've run them through the HCL
[13:53:57] <_methods> http://volterainc.com/
[13:54:09] <_methods> that thing actually looks kinda cool
[13:57:48] <CaptHindsight> it says two layer but it doesn't have any details on how it does vias
[14:01:46] <CaptHindsight> you can diy one similar with a mini mill, just add a micro valve for dispensing silver ink
[14:01:46] <_methods> i saw it printing a diff blue ink
[14:01:49] <_methods> so i'm not sure
[14:02:01] <CaptHindsight> silver ink recipe http://jordanbunker.com/archives/41
[14:02:07] <_methods> ah cool
[14:02:24] <_methods> looks like they have a hot plate built in too for reflow
[14:02:32] <CaptHindsight> drill vias and print conductive ink into the holes
[14:02:46] <_methods> they didn't show how they were cutting the boards either or drilling anything
[14:02:51] <_methods> i guess its meant to be all smd
[14:02:53] <CaptHindsight> or use silver solder paste
[14:04:17] <CaptHindsight> yeah, the volterainc looks like single sided smt unless they aren't showing everything on the website
[14:05:19] <_methods> i'm sure they want way too much for that
[14:05:23] <CaptHindsight> if thats all it is then you can use a modified thermal inkjet printer and print silver ink onto fr4
[14:05:26] <_methods> i'll just stick to my handy dandy pcb mill
[14:06:41] <CaptHindsight> http://hackaday.com/2013/12/05/instant-inkjet-circuits-with-silver-nanoparticle-ink/
[14:07:21] <CaptHindsight> there was also an Australian group on indegogo or similar that sold you ink and cartridges (HP Gen1)
[14:08:24] <CaptHindsight> http://www.thecrowdfundnetwork.com/silver-nanoparticle-ink-turns-your-printer-into-a-circuit-board-factory/
[14:08:30] <_methods> oh yeah i remember that thing
[14:08:34] <CaptHindsight> https://www.kickstarter.com/projects/1597902824/agic-print-printing-circuit-boards-with-home-print
[14:10:08] <CaptHindsight> silver costs much more than solver so it's only used in limited applications, copper ink is more complicated to make and print with since it oxidizes so rapidly
[14:10:17] <CaptHindsight> solver/silver
[14:11:44] <_methods> just easier to buy copper drops and cut my own
[14:11:50] <CaptHindsight> https://www.kickstarter.com/projects/cartesianco/the-ex1-rapid-3d-printing-of-circuit-boards
[14:12:25] <CaptHindsight> https://www.kickstarter.com/projects/electroninks/circuit-scribe-draw-circuits-instantly
[14:13:05] <CaptHindsight> heh, they took silver ink and put it in a pen and
[14:13:22] <_methods> you mean like the pens they already have lol
[14:13:35] <CaptHindsight> people actually paid for that vs diy or off the shelf
[14:13:39] <_methods> omg and they got $600k
[14:13:46] <CaptHindsight> yup, amazing
[14:13:50] <_methods> sucker born everyday i guess
[14:14:10] <CaptHindsight> I'm trying to see what the actual price of pen with ink was
[14:14:16] <_methods> it's like tv infomercials for hipster douche bags
[14:14:45] <_methods> kickstarter = as seen on tv lol
[14:14:48] <CaptHindsight> looks like $20 for the pen with ink
[14:15:13] <CaptHindsight> 10 for $175
[14:15:35] <CaptHindsight> I really overestimate people
[14:15:43] <_methods> http://www.all-spec.com/products/CW2000.html?gclid=CLj44MnYh8MCFWho7AodZRsAhA
[14:15:44] <_methods> me too
[14:16:02] <_methods> just shows all you need is a pretty picture or video and the suckers will appear
[14:16:15] <_methods> $20 for $9 pen lol
[14:17:30] <CaptHindsight> does it say anywhere how much ink was in them?
[14:17:45] <_methods> in the kickstarter ones?
[14:18:08] <_methods> i couldn't bring myself to watch the pen one lol
[14:18:13] <_methods> i was laughing too hard
[14:18:29] <_methods> i needed a good laugh though
[14:18:38] <_methods> got 2000 parts coming back :(
[14:18:41] <CaptHindsight> heh, they used Jordans ink
[14:18:42] <_methods> $50k
[14:19:07] <_methods> all the paint is peeling off
[14:19:18] <CaptHindsight> he publish the howto to make it open
[14:20:30] <_methods> http://jordanbunker.com/archives/41
[14:20:31] <mozmck> _methods: ouch!
[14:20:32] <_methods> that one?
[14:20:35] <_methods> yeah ouch
[14:20:38] <CaptHindsight> yes
[14:20:48] <_methods> our painter is fukd
[14:20:55] <_methods> he's probably gonna go out of business from this
[14:21:03] <CaptHindsight> what did he paint?
[14:21:04] <mozmck> I had to re-finish a banjo I made because it started peeling.
[14:21:05] <_methods> and i'll be blasting parts for the next month
[14:21:21] <_methods> he screwed up the acid etch on a bunch of alum parts
[14:21:21] <mozmck> I used a water-based lacquer. Never again.
[14:21:27] <_methods> carc
[14:21:31] <CaptHindsight> mozmck: does it sound any different? :)
[14:21:35] <_methods> all the carc is peeling
[14:21:45] <_methods> well chipping off
[14:21:54] <_methods> you can peel it off with your fingernail
[14:21:58] <_methods> no adhesion
[14:22:01] <_methods> total nightmare
[14:22:09] <CaptHindsight> carc?
[14:22:20] <_methods> NBC paint
[14:22:23] <mozmck> CaptHindsight: no, but for a banjo a couple of months old, the lacquer should not have been coming off!
[14:22:25] <_methods> chemical resistant
[14:22:38] <_methods> nuclear biological chemical paint
[14:22:46] <_methods> made to withstand decon cycles
[14:22:47] <Rab> http://en.wikipedia.org/wiki/Chemical_Agent_Resistant_Coating
[14:22:50] <_methods> yes
[14:23:00] <CaptHindsight> _methods: liquid coating or powder?
[14:23:04] <_methods> liquid
[14:23:07] <_methods> high solid
[14:23:28] <_methods> he should have alodined the parts
[14:23:38] <_methods> but he chose to use that crappy acid etch stuff
[14:23:51] <CaptHindsight> was a two part epoxy or polyester?
[14:24:01] <_methods> i'm not sure exactly
[14:24:31] <_methods> i'd have to see what he ordered
[14:24:39] <_methods> we just give him the color rqmnt
[14:24:45] <_methods> and let him choose his processes
[14:25:08] <_methods> it can be either epoxy or polyester i guess
[14:25:56] <_methods> 4 pallets full of parts though
[14:26:03] <_methods> :(
[14:50:13] <witnit> _methods :( I had a guy run about a 1,000 of a part I make, they were bad and he got them mixxed into the crate with 2,000 ones which were already good and ready to go
[14:50:29] <witnit> needless to say, he checks his parts with much more scrutiny now :)
[14:50:58] <CaptHindsight> and this wasn't even in China
[14:51:52] <CaptHindsight> http://everyspec.com/MIL-SPECS/MIL-SPECS-MIL-DTL/download.php?spec=MIL-DTL-53072C.011404.PDF
[14:54:24] <CaptHindsight> http://everyspec.com/library.php great site for specs by the way
[14:57:50] <CaptHindsight> https://www.youtube.com/watch?v=oetxtZtCFZ8 ok here's another racket, inkjet pen printer, these sell for >$200K
[14:59:08] <CaptHindsight> https://www.youtube.com/watch?v=zYUPG8AG2Vs mini one for $30K
[16:04:12] <zeeshan> CaptHindsight: ink!?
[16:04:12] <zeeshan> CaptHindsight: ink!?
[16:04:13] <zeeshan> :D
[16:12:44] <Rab> Figured out the pinout for my servos...picture from an eBay auction for a different Sanyo-Denki motor with a different encoder, but used the same wire colors and had the color code on the label.
[16:13:23] <Rab> Wired it up, scoped the outputs, worked exactly as hoped.
[16:13:34] <zeeshan> nice
[16:13:38] <zeeshan> the question is
[16:13:42] <zeeshan> what do you intend to do with them?
[16:13:45] <zeeshan> mail them to zeeshan? :D
[16:14:09] <Rab> zeeshan, sure you want to pay postage? They're heavy.
[16:14:15] <zeeshan> :D
[16:14:27] <zeeshan> im just trolling
[16:14:34] <zeeshan> i do need 2 servoces for A and C axis
[16:16:51] <zeeshan> Rab if you ever see a nice fluke multimeter
[16:16:59] <zeeshan> for cheap let me know!
[16:17:31] <zeeshan> http://www.homedepot.ca/product/milwaukee-digital-multimeter/912079

[17:29:04] <zeeshan> furrywoolf
[17:29:07] <zeeshan> where you be?!
[17:33:59] <XXCoder> wolf be at nowhere
[18:01:33] <PetefromTn_> evening folks.
[18:03:59] <furrywolf> heyas
[18:04:44] <furrywolf> grrr, I really wish I had a better internet connection.
[18:05:11] <XXCoder> hey wolf
[18:05:12] <PetefromTn_> well worked day two at my new part time Machine shop job today....
[18:05:25] <XXCoder> how was it
[18:05:38] <PetefromTn_> and my 25 minute drive home turned out to be about two and a half hours or so..
[18:05:52] <furrywolf> traffic, vehicle problems, ?
[18:05:53] <PetefromTn_> any guesses why?
[18:05:58] <_methods> explosions
[18:06:05] <Jymmm> So basically you are in the hole gas vs pay wise
[18:06:06] <PetefromTn_> no
[18:06:08] <XXCoder> superman blcoked the line
[18:06:18] <PetefromTn_> something like that hehe
[18:07:15] <PetefromTn_> actually the President of the United States was in Oak Ridge today speaking and his route home to the Air Force one waiting at Tyson Mcghee Airport in Maryville goes right down the Pellissippi parkway I drive to work on and back every day...
[18:07:49] <PetefromTn_> I was not aware we had that many Police officers/Cars in the country hehe
[18:07:57] <XXCoder> lol not common event eh
[18:07:59] <Jymmm> Obuma mucking it up for everyone... again
[18:08:14] <furrywolf> troll much?
[18:08:20] <PetefromTn_> I swear even the back roads I tried to take were parking lots...
[18:08:46] <PetefromTn_> literally sat in my Bronco listening to Pink Floyd for two and a half hours today
[18:08:56] <XXCoder> did you turn engine off?
[18:09:07] <PetefromTn_> left work at 4:15 and got home at almost 7PM
[18:09:12] <PetefromTn_> occasionally.
[18:09:28] <PetefromTn_> It was moving about just enough to make that a once in awhile thing.
[18:09:40] <PetefromTn_> I knew it was going to be bad but I HAD NO IDEA>>...
[18:09:57] <PetefromTn_> but as far as work it was pretty good today.
[18:10:13] <PetefromTn_> They had me working on the lathe running some damn stainless parts.
[18:10:14] <XXCoder> thats good. today is one of my very rare sick days
[18:10:22] <XXCoder> really nasty cough
[18:10:22] <PetefromTn_> I HATE STAINLESS
[18:10:29] <PetefromTn_> that sucks..
[18:10:29] <_methods> nice splinters
[18:10:30] <furrywolf> heh, I need to work on someone's bronco... snapped the pinion shaft on the front axle.
[18:11:18] <PetefromTn_> worst part is they had a 3.125" deep pocket in the barstock 1.125" diameter..
[18:11:43] <PetefromTn_> flat bottomed and there had to be a VERY SMOOTH and precise bore and floor to the pocket
[18:11:54] * furrywolf has noticed the new guy always gets the jobs no one else wants
[18:11:58] <PetefromTn_> so plenty of chances for a screwup...
[18:12:40] <PetefromTn_> I managed to make a bunch and they looked sweet and were to spec so I might have impressed them just a tad ;)
[18:13:24] <PetefromTn_> I did break off a 1" drill bit in one tho LOL.. I was able to remove it and get back to finishing that part without scrapping it. Damn bit was all fubared anyways.
[18:13:43] <furrywolf> probably why it broke
[18:13:55] <furrywolf> I need to get good at sharpening bits... I suck at it.
[18:14:29] <PetefromTn_> well actually the flutes were nice but the shank had slipped in the chuck apparently for other guys about a million times so it was really burred up and fugly.
[18:14:29] <furrywolf> or I need to see if 4-axis is enough to sharpen one properly with a diamond wheel in the spindle, and write a program to do it, one or the other. :P
[18:14:56] <PetefromTn_> for a drill bit?
[18:15:07] <furrywolf> I decided a while ago that if I used a faceted instead of conical grind I could do a good job with 4-axis, but I don't remember why I decided that.
[18:15:11] <furrywolf> yes
[18:15:16] <PetefromTn_> we just usually hand sharpen them or buy another one heh
[18:15:24] <furrywolf> yeah, I suck at that.
[18:15:37] * furrywolf sucks at most manual dexterity tasks... soldering SMT sucks!
[18:15:59] <PetefromTn_> drill bits are cheap enough it is usually not worth the time to screw with them other than just a quick cleanup on the wheel.
[18:16:51] <furrywolf> the only cheap bits are chinese, and they're usually useless.
[18:16:57] <furrywolf> a good US-made bit is not cheap.
[18:17:09] <PetefromTn_> the owner who is also a machinist actually told me he recommended some kinda kobalt drills index from Harbor Freight today... Blew my mind.
[18:17:27] <PetefromTn_> but I used a bunch of them today and I gotta admit they were not bad.
[18:17:42] <PetefromTn_> Apparently the whole index is like a hundred bucks or something.
[18:18:05] <furrywolf> I've used the chinese non-cobalt one like that... they're good for one, maybe two holes each...
[18:18:21] <moorbo> PetefromTn_: I imagine with time as they get better, their products will get better
[18:18:47] <PetefromTn_> yeah like I said they were not bad.. they seemed to drill that stainless okay.
[18:19:51] <PetefromTn_> they got a nice little surface grinder over in the corner of the shop that they said had some kinda problem
[18:20:08] * SpeedEvil idly wonders how much force you need to keep a wood-plane blade tracking without the plane
[18:20:09] <PetefromTn_> It looked like it was in good condition overall...
[18:20:31] <PetefromTn_> might have to look it over and make them an offer cheap LOL
[18:26:29] <_methods> you can get surface grinders all day for dirt cheap
[18:26:39] <_methods> i just saw 3 go at auction for like $75
[18:26:50] <furrywolf> grrr!
[18:26:53] <PetefromTn_> yeah but are they fubar'd?
[18:27:05] <_methods> we just got a 4'x8'x16" surface plate for $175
[18:27:15] <_methods> gotta go to atl next week to pick it up
[18:27:31] <_methods> i got 2 lista cabinets for $65 each too
[18:27:32] <PetefromTn_> WOW thats a beast
[18:27:56] <_methods> nice to have all that real estate when you need to inspect big parts
[18:27:57] <SpeedEvil> How many of you are going?
[18:28:06] <_methods> probably just 2?
[18:28:07] <_methods> why
[18:28:15] <SpeedEvil> And/Or have you started taking the roids already?
[18:28:23] <SpeedEvil> Wait
[18:28:25] <_methods> heh that's what riggers ar for
[18:28:29] <SpeedEvil> 4'*8'*16"
[18:28:39] <SpeedEvil> That is ratehr bigger than I read at first
[18:28:46] <_methods> yeah
[18:28:50] <PetefromTn_> shit's hydro heavy LOL
[18:28:53] <_methods> i won't be lifting that lol
[18:28:57] <_methods> 5300lbs
[18:29:00] <SpeedEvil> That's what - 3 tons?
[18:29:03] <_methods> so not that bad
[18:29:30] <_methods> our little forklifts should be able to get it
[18:29:47] <SpeedEvil> Overkill - when the surface plate weighs more than the slab the building is built on
[18:29:57] <PetefromTn_> I need to find a decent used fourth axis for my VMC at one a dem tings..
[18:29:59] <moorbo> OH
[18:30:00] <moorbo> GOD
[18:30:16] <moorbo> the last stepper movement I did had F20....
[18:30:19] <_methods> yeah they had a bunch at that auction i got that plate at
[18:30:21] <moorbo> and now I moved to the opposite corner
[18:30:25] <moorbo> >_<
[18:30:28] <furrywolf> I have a rotary table I was thinking of CNCing for a 4th axis.
[18:30:36] <_methods> they had 2 big 5 axis machines
[18:30:39] <PetefromTn_> what they go for?
[18:30:59] <_methods> i think the one that was 40" x 60" x 24" went for $45k
[18:31:11] <PetefromTn_> no the rotabs..
[18:31:11] <_methods> the other big 8' cinci went for like $110
[18:31:19] <_methods> $110k
[18:31:27] <_methods> oh shit i didn't look
[18:31:35] <XXCoder> man http://www.lileks.com/institute/comicsins/comicads/guns/8.html lot changes since then. train, bus and airplane? yeah right lol
[18:31:36] <_methods> i see so many rotabs i don't even look at them anymore
[18:31:56] <_methods> i'll keep an eye out for you though if you want
[18:32:09] <_methods> you want a full 4th?
[18:32:13] <_methods> or just a rotab?
[18:32:13] <PetefromTn_> yeah man. I would like to get a smokin' deal on one...
[18:32:16] <PetefromTn_> fourth
[18:32:19] <_methods> k
[18:32:23] <_methods> yeah i'll watch
[18:32:34] <PetefromTn_> you are not TOO far away from me aren't ya?
[18:32:39] <_methods> we got 2 haas and 2 yaskawas at the shop
[18:32:44] <_methods> so i really don't evenlook at them
[18:33:03] <PetefromTn_> 5C's or full fourth's?
[18:33:12] <_methods> full 4ths
[18:33:32] <_methods> not sure why we have so many
[18:33:36] <_methods> we only ever use 1 lol
[18:33:39] <PetefromTn_> they got a nice brand new VF3 at the shop I started working in. BRAND SPANKIN!
[18:33:50] <furrywolf> xxcoder: you still can pack guns on trains, busses, and planes... they just have to, in the case of planes, be in checked baggage, unloaded, and in a hard-sided case.
[18:34:11] <PetefromTn_> has tool and spindle remote probing and fourth axis pretty sweet it is also the extended travel one.
[18:34:13] <XXCoder> yeah there is people who use the fact that they have to use their own lock
[18:34:23] <XXCoder> and guns list include starter gun
[18:34:31] <_methods> wow haas with tool probe lol
[18:34:37] <XXCoder> it does not fire bullets but just caps
[18:34:43] <_methods> stupid haas
[18:34:48] <_methods> they nickle and dime you to death
[18:34:49] * furrywolf wonders what the difference between a rotary table and a full fourth axis is...
[18:34:54] <_methods> $5k for lights
[18:34:59] <_methods> oh you want a door?
[18:35:02] <_methods> $4k
[18:35:03] <XXCoder> does anyone here like haas
[18:35:10] <PetefromTn_> I do
[18:35:13] <_methods> 20mb ram
[18:35:17] <_methods> that will be $10k
[18:35:23] <furrywolf> xxcoder: on planes, fire is an even bigger risk than the security risk.
[18:35:24] <_methods> oh you want usb
[18:35:29] <_methods> that's anohter $20k lol
[18:35:51] <PetefromTn_> actually they told me the whole thing was like $85k or something like that..
[18:35:55] <_methods> i just drip feed all of ours
[18:36:03] <_methods> and use a flashlight
[18:36:10] <PetefromTn_> LOL
[18:36:19] <XXCoder> the gaintass router haas cost just $100k (pre-options)
[18:36:23] <PetefromTn_> They also have a big leadwell V40
[18:36:34] <XXCoder> giantass
[18:36:56] <furrywolf> so... what do you add to a rotary table to make it a full fourth axis? I usually figure a chuck screwed to a rotary table is a pretty good 4th axis...
[18:37:11] <_methods> your controller
[18:37:45] <_methods> the controller moves the rotab
[18:38:21] <furrywolf> wouldn't that be implied? heh
[18:38:31] <_methods> no a rotab is just a rotab lol
[18:38:34] <_methods> you move it by hand
[18:39:45] <furrywolf> in the context of adding a 4th axis to a cnc mill, I'd figure it implied cnc too. lol
[18:40:19] <_methods> i've used plain old rotabs on 3 axis vmc's before
[18:40:34] <_methods> sometimes you just need a chuck or whatever in there
[18:41:00] <furrywolf> I currently have a non-cnc rotary table I want to stick a stepper to, to use as a 4th axis...
[18:41:50] <PetefromTn_> LOL Red forman is on Star Trek Voyager hehe
[18:42:25] <XXCoder> heh little change to red foreman and it sounds like comic consection themed villian
[18:42:29] <furrywolf> methinks you mean "was", as I think that stopped airing a long time ago...
[18:43:02] <PetefromTn_> no I mean IS as in I IS watching it right now LOL
[18:44:06] <furrywolf> voyager always annoyed me too much to watch. it's like a comittee-designed star trek... let's pick a cast of characters based on the maximum potential for interpersonal conflicts instead of actual plot...
[18:44:42] <PetefromTn_> yeah but.....three words.....SEVEN OF NINE!!!
[18:45:25] <_methods> PetefromTn_: what price are you lookin for on 4th and what size?
[18:45:56] <PetefromTn_> CHEAP!!!! oh yeah and did I mention.....CHEAP!! LOL
[18:46:03] <_methods> $200?
[18:46:04] <PetefromTn_> an eight inch or so would be fine.
[18:46:12] <PetefromTn_> sure
[18:46:12] <_methods> k
[18:46:22] <_methods> i'll watch for ya
[18:46:26] <Tom_itx> that's what she said
[18:46:35] <PetefromTn_> I guess it depends on what it is really....
[18:46:37] <_methods> hehe
[18:46:50] <furrywolf> notice the original star trek was about the cast fighting external problems, with the only interpersonal conflicts being humorous jibes between the three stars... while in voyager, what, HALF the fucking episodes are about characters having conflicts with each other in some fashion? vulcan vs human vs marquis vs borg etc etc etc...
[18:46:54] <PetefromTn_> if it is real nice I might be able to scrape up some more...
[18:47:12] <_methods> well i wouldn't pay more than $200 lol
[18:47:16] <_methods> i see them go for that
[18:47:22] <PetefromTn_> NICE...
[18:47:31] <_methods> i just saw a bridgeport go for $475
[18:47:38] <_methods> killed me
[18:47:46] <_methods> not enough room in the garage
[18:47:47] <PetefromTn_> furrywolf Honestly my favorite trek series is DS9...similar interpersonal relationships all the time.
[18:47:51] <furrywolf> hrmm, where are you seeing an 8" cnc table go for $200? on ebay I've only seen manual tables anywhere in that range...
[18:48:01] <_methods> ebay lol
[18:48:20] <_methods> i'm not giving up my secret fishin holes man
[18:48:33] <furrywolf> pete: ah, ds9... let's add spirituality and religion into a world that's supposed to have, according to roddenberry, advanced enough to eliminiate all that crap...
[18:49:24] <PetefromTn_> yeah well be that as it may...I like it.
[18:49:47] <PetefromTn_> and I don't really want to get into an argument about what it should or should not have been....I am too tired.
[18:49:52] <furrywolf> lol
[18:50:23] * furrywolf googles
[18:50:26] <furrywolf> "I condemn false prophets, I condemn the effort to take away the power of rational decision, to drain people of their free will -- and a hell of a lot of money in the bargain. Religions vary in their degree of idiocy, but I reject them all. For most people, religion is nothing more than a substitute for a malfunctioning brain." (Gene Roddenberry)
[18:50:29] <furrywolf> there we go. :)
[18:50:53] <furrywolf> he ever so slightly didn't like religion...
[18:55:55] <_methods> CaptHindsight: http://www.voxel8.co/
[18:57:01] <furrywolf> if you come across a cheap cnc 5"-6" table, let me know. :P
[18:57:26] * furrywolf only has a chinese mill/lathe combo machine, that won't fit anything larger
[18:57:32] <furrywolf> my current table is tiny...
[18:57:41] <_methods> 5" table?
[18:57:43] <furrywolf> it came with my sherline, and is appropriately scaled for it. :)
[18:57:45] <_methods> cnc ?
[18:57:46] <furrywolf> rotary table
[18:57:48] <_methods> oh
[18:57:52] <_methods> ok
[18:57:55] <_methods> yeah i'll watch out
[18:58:06] <CaptHindsight> _methods: looks like they added more info
[18:58:17] <_methods> that's another one
[18:58:37] <_methods> apparently 2015 is the year of 3d pcbs lol
[18:58:40] <CaptHindsight> saw that a few days ago
[18:58:52] <CaptHindsight> FDM with a nozzle for silver paste
[18:59:12] <_methods> thing is $9k lol
[18:59:30] <CaptHindsight> and 10 supposed patents
[18:59:41] <_methods> i can get 2 x2's and build a bad ass 3d printer for that price lol
[18:59:45] <CaptHindsight> slow and expensive, low res
[19:00:13] <CaptHindsight> and still only single sided
[19:00:22] <_methods> yeah
[19:01:28] <furrywolf> if I ever decide to build a 3d printer, I'll probably just chuck an extruder in the spindle of my mill... no reason to build a new xyz stage for the fun of it.
[19:01:34] <CaptHindsight> but all the glue gun nuts will go apeshit over it
[19:02:09] <CaptHindsight> I call it "Filament Fetish"
[19:02:20] <furrywolf> lol
[19:02:41] <SpeedEvil> furrywolf: It's a _lot_ of cycles on the mill slides
[19:03:05] <furrywolf> speedevil: not any more than pocket milling in a hard material with shallow cuts...
[19:03:10] <SpeedEvil> true
[19:03:17] <furrywolf> and there's no stress on them at all, unlike pushing a cutter through metal.
[19:03:44] <furrywolf> and, that implies I'd ever use it more than twice. :P
[19:06:23] <CaptHindsight> zeeshan: ink?
[19:07:42] <CaptHindsight> _methods: http://static.squarespace.com/static/54a59cdce4b0e8454933affc/54a6ed46e4b0970e0f112f11/54a6efb6e4b0d05e1aa753a8/1420226486958/antenna2.jpg?format=500w
[19:08:04] <CaptHindsight> not sure if this pic is part of that printer or some better project
[19:08:08] <_methods> wow
[19:08:32] <_methods> nice
[19:08:34] <CaptHindsight> http://www.voxel8.co/about/ it's one of the images from the About page
[19:08:54] <_methods> that doesn't look like what i saw that thing putting out lol
[19:09:19] <CaptHindsight> that is a nozzle on a pneumatic valve
[19:09:38] <CaptHindsight> we put those on little gantry printers all the time
[19:10:22] <_methods> interesting
[19:10:31] <_methods> what do you use for metering?
[19:11:39] <CaptHindsight> http://imagebin.ca/v/1nbjHlg3CndI
[19:12:50] <CaptHindsight> http://imagebin.ca/v/1nbjgQvB5Czw the valves are like this
[19:13:13] <_methods> how much do those things run
[19:13:19] <CaptHindsight> you adjust the fluid pressure and the amount that the valve opens
[19:13:26] <_methods> i'd like to make a cnc solder paste disp with one of those
[19:13:26] * furrywolf spots the harbor freight t-handle ball-nose hex wrench set
[19:13:51] <CaptHindsight> that gives you a set flow rate
[19:14:21] <CaptHindsight> you just toggle the valve on/off at the start/end of each segment
[19:14:23] <_methods> assuming your medium is same viscosity?
[19:14:43] <CaptHindsight> yes, it's the same viscosity at a given temp
[19:14:51] <CaptHindsight> unless it's poorly mixed
[19:15:12] <_methods> interesting
[19:15:24] <_methods> so how much do those setups run?
[19:15:34] <_methods> and how much air/psi?
[19:16:04] <_methods> sorry for all the questions
[19:16:12] <CaptHindsight> Nordson sells the vales for $500-1K, and a 3 axis gantry for $60K
[19:16:24] <furrywolf> capt: what are you making, anyway? (I missed the first part of this conversation)
[19:16:54] <CaptHindsight> 125psi max on the valve, 0-70psi on the fluid
[19:17:20] <_methods> well the valve price blows my 2nd plan for it lol
[19:17:33] <CaptHindsight> furrywolf: we are just discussing some printed circuit board printers
[19:17:36] <_methods> i was thinking about making a cnc bar bot with that valve lol
[19:17:42] <CaptHindsight> used on ebay for ~$100
[19:17:56] <_methods> everyone uses those peristatlic pumps
[19:18:31] <_methods> i guess i could buy one of those valves and make a ghetto copy for my bar bot
[19:18:33] <CaptHindsight> depends on the pressure and flow rate you need
[19:19:29] <furrywolf> wouldn't a bar bot have tolerances more than adequately served by cheap options?
[19:19:49] <_methods> yes and no
[19:19:51] <CaptHindsight> http://www.ebay.com/itm/EFD-Valve-Air-Pressure-70-psi-4-8-Bar-Dispense-Valve-/221632312223
[19:20:22] <_methods> it's food grade so anything food grade is usually a PITA
[19:21:04] <CaptHindsight> depending on viscosity you could just use a syringe and syringe pump
[19:21:15] <_methods> yeah alcohol
[19:21:18] <CaptHindsight> they just don't respond as quickly
[19:21:28] <_methods> i just want simple and eaasy to clean
[19:21:38] <furrywolf> what do the new coke machines use, and how long before they hit the scrapyards?
[19:22:04] <_methods> and something besides peristaltic
[19:23:02] <_methods> syringe and syringe pump would probably do the trick
[19:24:03] <furrywolf> http://en.wikipedia.org/wiki/Coca-Cola_Freestyle those
[19:24:10] <furrywolf> (had to google for the name, never used one)
[19:24:14] <_methods> yeah the ebola machine
[19:25:19] <furrywolf> ?
[19:25:50] <_methods> everyone goin up there and puttin their bugger fingers all over the machine
[19:26:13] <_methods> you have to touch this nasty screen with little kids booger hand prints all over it
[19:26:58] <furrywolf> I'm more thinking it's only a matter of time before they start getting scrapped, and probably have a quite nice assortment of precise metering pumps.
[19:27:02] <_methods> i call them the coca ebola machines
[19:27:19] <furrywolf> I don't drink soda... I call them foul-tasting sugarwater machines.
[19:30:17] <furrywolf> figure every cartridge slot has a very precise pump or valve associated with it...
[19:31:28] <_methods> CaptHindsight: thanks for the syringe pump idea that one hadn't crossed my mind
[19:35:06] <CaptHindsight> http://www.3ders.org/articles/20141002-italian-studio-lab-unveils-open-source-syringe-extruder-for-fdm-3d-printers.html ghetto version
[19:36:22] <LeelooMinai> Could be good for making cookies though
[19:36:29] <_methods> hah and here i was thinking of using a linear actuator
[19:36:45] <furrywolf> for a barbot you'll need a lot more speed than that design has.
[19:37:22] <_methods> not or like a real bar
[19:37:36] <_methods> i just want to make something for the house that's cheap and sanitary
[19:37:57] <_methods> s/or/for

[19:38:56] <furrywolf> edible mexican food?
[19:39:02] <CaptHindsight> lol
[19:39:06] <furrywolf> :P
[19:39:08] <LeelooMinai> How did they manage to pull that off...
[19:39:35] <furrywolf> I actually like mexican food... I dislike most of the stuff sold as mexican food.

[19:42:10] <furrywolf> I don't think I want any "food" that can be extruded from a syringe.

[20:05:08] <jdh> what do people use for modeling for low end 3d printers?
[20:05:37] <malcom2073> jdh: I use solidworks
[20:05:56] <jdh> what free software do people use for modeling for low end 3d printers?
[20:06:06] <malcom2073> freecad, openscad, designspark mechanical
[20:06:10] <malcom2073> wait, I have a link for you
[20:06:46] <malcom2073> jdh: http://reprap.org/wiki/Useful_Software_Packages
[20:07:15] <jdh> thanks
[20:07:18] <malcom2073> But the most common ones I hear about are openscad, freecad, and sketchup
[20:26:53] <SpeedEvil> Blender.
[20:26:58] <SpeedEvil> If you are clinically insane.
[20:30:28] * Jymmm raises hand
[20:31:00] <Jymmm> oh clinically, not institutionally, lowers hand.
[20:33:13] <_methods> ok both
[20:33:22] <_methods> now get your hand back up
[20:34:05] <SpeedEvil> After spending ~ a week or so fighting it - I've come to the conclusion that - with the right tutorials - blender could be a usable - perhaps not great - CAD program for simple stuff.
[20:34:08] <_methods> the local hackerspace got a free shapeoko from a contest
[20:34:23] <_methods> they asked me to come in there and help them learn how to use it lol
[20:34:36] <SpeedEvil> The problem is that 99.9% of the tutorials are 'ok, now click this button, and wave the mouse around till it's about in the right place'
[20:34:42] <SpeedEvil> which isn't ideal for much CAD.
[20:34:43] <_methods> there's this guy in there i can't stand named stewart
[20:35:00] <_methods> i'm gonna go in there and for the sample part i'm gonna carve a paynis with his name on it
[20:35:16] <SpeedEvil> You _need_ to understand local and global axis, the coordinate system, and how to snap to crap.
[20:35:27] <malcom2073> Blender is an art program isnt it?
[20:35:28] <malcom2073> heh
[20:35:36] <malcom2073> It has to look good, not be precise :P
[20:35:56] <SpeedEvil> malcom2073: basically yes. It's got so many features it is also usable - sort of as a solid modeler - if you know what bits not to touch.
[20:36:06] <malcom2073> yeah
[20:36:19] <malcom2073> I used it a while back, but realized I'm not in the slightest artistic, so I stick to CAD programs for 3d modeling stuff heh
[20:36:56] <SpeedEvil> But 'what bits not to touch' include stuff like random keypresses - alt-B for examlpe, instead of shift-b sets you to a fun mode where you've just wiped out all of the view - until you re-press alt-b.
[20:37:00] <SpeedEvil> shift-b is box select
[20:37:25] <malcom2073> lol
[20:38:58] <SpeedEvil> Or 'I now have a lovely solid model of a gearbox, but I can't work out how to remove the orange fur'
[20:39:41] <malcom2073> lol
[20:40:04] <malcom2073> Anyone here played with any of the DIY servobelt drive systems?
[21:16:52] <t12> sdfsdf
[21:16:54] <t12> er
[22:11:12] <furrywolf> hate my connection, so much...
[22:25:17] <Computer_Barf> are angled gibs supposed to settle with gravity?
[22:25:29] <Computer_Barf> https://www.youtube.com/watch?v=QjUTJi3Xk5o
[22:27:01] <Computer_Barf> this mod he reverses the head plate as to gain movement, but I wonder about the gibs being upside down like that, and also the rigidity affected by the lack of length on the bottom causing cantilever flex
[22:27:53] <furrywolf> gibs should be supported by an adjustment mechanism of some kind, either locking screws for straight gibs, or a slide mechanism for tapered gibs. gravity should have nothing to do with your mill's adjustments...
[22:29:39] <Computer_Barf> yes the g0704 has screws that hold the gibs in place, but i figured that there was some reasoning behind the tapered gibs being on top
[22:30:20] <_methods> wtf is up with that video
[22:30:23] <_methods> shit refuses to load
[22:30:36] <_methods> .wmv
[22:30:53] <furrywolf> I didn't even bother trying to load the video. it's youtube, so I know it's going to suck.
[22:31:20] <Computer_Barf> played fine for me , but ive noticed youtube acting funky lately. This new autoplay feature seems to cause videos to randomly skip to the next video mid play for me.
[22:31:37] <_methods> it's .wmv takin forever to load
[22:31:52] <Computer_Barf> how do you know its a .wmv on youtube/
[22:32:12] <_methods> it says .wmv on it?
[22:32:15] <XXCoder> title name
[22:32:25] <_methods> and besides he's using mach
[22:32:34] <_methods> so that's like 2 strikes against already lol
[22:33:22] * _methods gives up and goes back to looking at diy pipe benders
[22:33:38] <Computer_Barf> lol. well hoss does have alot of g0704 material, he sells the plans and such so alot of the g0704 folks get some info from him.
[22:34:15] <Computer_Barf> I got my kit from someone else but hoss has videos up on most every mod on these machines
[22:34:40] <_methods> his website is a train wreck
[22:34:55] <Computer_Barf> I do admit, i find his voice a bit hard to listen to
[22:35:26] <furrywolf> between youtube's shit player (the best way to watch youtube videos is to download them and use a proper player), and my lack of bandwidth (>ten times download time to play time ratio), I just ignore youtube links.
[22:35:56] <Computer_Barf> I often use youtube-dl when i find a channel I like
[22:36:03] <_methods> shit i'll be smoking crack and watching youtube all night
[22:36:16] <_methods> but not .wmv youtube lol
[22:57:13] <zeeshan> https://www.flickr.com/photos/128539016@N05/16216978566/

[22:57:15] <zeeshan> :D
[22:59:43] <SpeedEvil> Woo!
[22:59:54] <zeeshan> i dont understand something
[22:59:56] <zeeshan> with the main breaker off
[23:00:06] <zeeshan> i have 17.1 Vac between l1 and ground/n
[23:00:10] <zeeshan> l2 and ground/n
[23:00:11] <zeeshan> wtf!
[23:00:38] <SpeedEvil> Connect a 10K resistor across it
[23:00:40] <SpeedEvil> - the meter
[23:00:51] <SpeedEvil> you're seeing capacitive coupling of adjacent wires
[23:01:11] <zeeshan> that much?
[23:01:14] <zeeshan> 17.1??!
[23:01:15] <zeeshan> vac
[23:01:38] <furrywolf> and this is why you don't share servo drive and encoder wires in the same bundle, for example. :P
[23:01:55] <SpeedEvil> zeeshan: into what is presumably a 1M input impedence meter.
[23:02:10] <SpeedEvil> this is a whole 300 microwatts or so of leakage
[23:02:33] <zeeshan> i feel like its some retarded capacitor
[23:02:35] <SpeedEvil> It might - if you short it - produce 30uA
[23:02:36] <zeeshan> plugged into the wall
[23:02:44] <SpeedEvil> zeeshan: it is. Adjacent wires are capacitors
[23:02:53] <zeeshan> which adjacent wires?
[23:02:56] <zeeshan> i turned off the main breaker
[23:03:00] <zeeshan> there are no adjacent live wires
[23:03:02] <SpeedEvil> ah
[23:03:25] <furrywolf> power supplies tend not to let capacitors leak back to the line
[23:03:36] <zeeshan> FREE EN ERGY guys
[23:03:39] <zeeshan> FREE ENERGY. i have discoverd it!
[23:04:22] <furrywolf> now try taping toast, buttered side up, to the back of a cat.
[23:04:45] <zeeshan> i wonder which device is pumping voltage
[23:05:04] <zeeshan> im gonna try turning of all the breakers and see what happerns
[23:05:08] <zeeshan> to isolate whats generating it
[23:05:19] <zeeshan> i mean 17Vac isnt enough to shock you
[23:05:25] <zeeshan> but im curious
[23:05:44] <furrywolf> if you're getting AC, it's definitely not some random capacitor leaking back to the line... it's picked up noise or a ground loop.
[23:06:16] <furrywolf> any non-active stored power would be producing dc
[23:06:31] <zeeshan> thats a good point
[23:06:58] <furrywolf> set your meter to its lowest current scale and see how many uA you get. :P
[23:07:21] <zeeshan> ill check tomorrow
[23:07:25] <zeeshan> i cant kill the pwoer now
[23:07:28] <zeeshan> downloading stuff :)
[23:08:15] <zeeshan> i dont know how im gonna fish wire through this
[23:10:20] <Tom_itx> fiberglass tape
[23:10:36] <zeeshan> i cant even make it past the first elbow
[23:10:40] <zeeshan> its getting stuck at a lip
[23:10:42] <zeeshan> w/ just one wire.. lol
[23:10:44] <zeeshan> yet along 3!
[23:10:46] <zeeshan> *alone
[23:16:03] <SpeedEvil> furrywolf: very few meters can do ACuA
[23:17:06] * furrywolf would consider "0" an acceptable reading. :P
[23:17:46] <furrywolf> also, my $39.99 chinese one does
[23:18:13] <furrywolf> I really, really hate my internet connection. right now I'm downloading firefox at 5.2K/sec. I might as well get a modem.
[23:28:48] <furrywolf> dialup would have a lot better reliability and latency...
[23:29:53] <XXCoder> what isp?
[23:30:24] <furrywolf> virgin mobile 3g
[23:30:38] <SpeedEvil> Is it poor signal?
[23:30:52] <SpeedEvil> or are you on 2g
[23:30:57] <furrywolf> it shows 2-3 bars...
[23:30:58] <XXCoder> ouch
[23:30:59] <furrywolf> 3g
[23:31:04] <XXCoder> 3g isnt that slow
[23:31:22] <furrywolf> xxcoder: it'll go up to 100K/sec when everyone isn't home and online
[23:31:40] <furrywolf> in a couple hours it'll work great. it'll also work great when I get up in the morning.
