[09:34:40] <ubu-_> hi MrHindsight
[09:34:56] <ubu-_> Do you use linuxcnc camera?
[09:38:24] <MrHindsight> it's helps if you speak Mandarin, and it really helps to get the lowest price by being Chinese, foreigners get instant price bump
[09:39:51] <MrHindsight> ubu-_: Linuxcnc with a camera? yes
[09:44:56] <ubu-_> yes MrHindsight , I don't want busy you :)
[09:45:18] <MrHindsight> ubu-_: just ask away , anyone might answer
[09:45:33] <ubu-_> thansk MrHindsight
[09:46:21] <ubu-_> MrHindsight: I don't install camview
[09:46:58] <ubu-_> how I do it? not packet found ,error.
[09:47:37] <MrHindsight> http://psha.org.ru/debian/README.html
[09:47:48] <MrHindsight> http://psha.org.ru/b/camview-emc.html
[09:48:52] <MrHindsight> if you install other way you really need to know what you're doing or you'll most likely have conflicts
[09:49:06] <MrHindsight> he needs to rewrite that howto to be more clear
[09:50:02] <ubu-_> I read all, but I 'm newbie
[09:50:21] <MrHindsight> did you follow all the steps?
[09:51:45] <ubu-_> yes but look again now, I will came 2 min.

[10:06:11] <_methods> heh
[10:07:47] <ubu-_> "deb " not command found
[10:08:09] <ubu-_> MrHindsight: do you use teamviewer ?
[10:08:18] <ubu-_> or _methods ?
[10:08:20] <ubu-_> :)
[10:13:49] <MrHindsight> which version of Ubuntu?
[10:14:16] <humble_sea_bass> ubuntu - saddest bird
[10:15:08] <MrHindsight> Add to /etc/apt/sources.list (or /etc/apt/sources.list.d/psha.org.ru.list) following line
[10:15:16] <ubu-_> lucic 10.04
[10:15:18] <MrHindsight> deb http://psha.org.ru/debian/ NAME-OF-YOUR-DISTRIBUTION contrib
[10:15:30] <MrHindsight> Replace NAME-OF-YOUR-DISTRIBUTION with one of supported distributions.
[10:16:10] <MrHindsight> so you would use: http://psha.org.ru/debian/ lucid contrib
[10:16:47] <ubu-_> /etc/apt/sources.list (or /etc/apt/sources.list.d/psha.org.ru.list)
[10:16:49] <ubu-_> No such file or directory
[10:17:16] <ubu-_> and
[10:17:34] <ubu-_> http://psha.org.ru/debian/ lucid contrib
[10:17:42] <ubu-_> again No such file or directory

[10:22:39] <ubu-_> MrHindsight: _methods
[10:22:47] <MrHindsight> is the file empty?
[10:23:39] <ubu-_> no
[10:23:44] <MrHindsight> probably not since you wanted to pastebin the contents
[10:24:14] <MrHindsight> so add this line in the repo list: http://psha.org.ru/debian/ lucid contrib
[10:25:13] <ubu-_> http://dpaste.com/1794628/
[10:25:16] <MrHindsight> then save the file
[10:25:50] <MrHindsight> ubu-_: ok then add the line I posted twice
[10:26:18] <MrHindsight> and save the file
[10:26:30] <ubu-_> ok add "http://psha.org.ru/debian/ lucid contrib" or "deb http://psha.org.ru/debian/ lucid contrib"

[11:00:27] <Loetmichel> GNAH, i could cry. 7h machine run.. and then i accidentally hit page down instead of page up.. -> http://www.cyrom.org/palbum/main.php?g2_itemId=14841
[11:00:36] <Loetmichel> what have i done to deserve this?
[11:01:19] <cradek> aww heck.
[11:01:43] <cradek> (7 hours for that??)
[11:03:09] <MrHindsight> fill it in, powder coat, will never notice
[11:03:37] <Loetmichel> cradek: 1/8" mill bit, chinese 6040
[11:03:49] <Loetmichel> so not more than 0,2mm depth per run
[11:03:57] <Loetmichel> tha sheet aluminium was 8mm thick
[11:04:22] <ubu-_> MrHindsight: very much thanks for all
[11:04:37] <cradek> oh yikes, that's a lot of cutting
[11:05:27] <Loetmichel> cradek: see here: https://www.youtube.com/watch?v=9GR2aihu0LQ
[11:05:27] <humble_sea_bass> roofles, NYC's high school drop out rate is at 40%, lowest in decades
[11:05:32] <humble_sea_bass> >>40%<<
[11:08:10] <MrHindsight> what's the unemployment rate for those 1-4 years after getting a Bachelors Degree?
[11:08:38] <ReadError> suppose it depends on the degree
[11:08:44] <MrHindsight> same jobs? with the dropout as their manager at McTaco?
[11:08:46] <ReadError> if you have some worthless art major
[11:08:51] <ReadError> I suppose its pretty high
[11:09:25] <humble_sea_bass> yeah but you normally don't go to art school in NYC if you're poor
[11:09:32] <humble_sea_bass> because they are expensive
[11:09:55] <MrHindsight> they don't have to work anyway
[11:10:26] <roh> Loetmichel: yikes. nice milljob.
[11:10:27] <MrHindsight> how many leave art school in NYC and get commercial art jobs?
[11:10:29] <humble_sea_bass> correct, they have a longer shelf life on their parent's dime
[11:11:02] <humble_sea_bass> if you are in art school, odds are you are not amazing and extroverted
[11:11:38] <MrHindsight> it's not the 50-'s-70's in the US anymore, a degree doesn't help many people
[11:11:45] <humble_sea_bass> my friend who goes by the name Neckface, was in art school for a bit, and was told that he was bad and his style was unsellable, now he is hot shit in the art world
[11:11:48] <ubu-_> humble_sea_bass: do you use psha camview?
[11:12:07] <humble_sea_bass> no ubu i do not
[11:12:23] <MrHindsight> silicon valley salary fixes, H1b visa scams, no jobs.....
[11:12:29] <Loetmichel> roh: especially yikes because thats the back of a cutomers casing
[11:12:37] <Loetmichel> so th holes are visible...
[11:12:59] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=14769
[11:13:02] <humble_sea_bass> I'm still floored. as a product of the NYC public school system, I didn't notice 50% drop out rate back then
[11:13:24] <humble_sea_bass> but I was segregated by the honors program I guess,
[11:13:38] <Loetmichel> (will be coated with blue and dark gray powder before delivering)
[11:14:05] <MrHindsight> aluminum solder rods to the rescue!
[11:14:59] <Loetmichel> MrHindsight: you know that powder coating gets 220°c in the process?
[11:15:08] <humble_sea_bass> that's a tight looking case Loetmichel
[11:15:25] <Loetmichel> so: no normal low temperature solder for aluminium (that i would have here)
[11:15:43] <Loetmichel> i'll try to get the part to our case manufacturaer tomorrow, he has a tig welder
[11:15:50] <Loetmichel> maybe he can fill the hole
[11:16:29] <MrHindsight> should not be a problem since you're coating it anyway
[11:16:53] <Loetmichel> humble_sea_bass: and with the hodd it is even more tight ;-)
[11:16:54] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=14781
[11:16:55] <MrHindsight> just more work :(
[11:18:25] <MrHindsight> that's a good example of where 3d printing is much faster than milling, 7 hrs milling vs 2 minutes SLA
[11:19:06] <Loetmichel> ha, nice
[11:19:15] <MrHindsight> though I'm sure by roughing out with larger tools would save time as well
[11:19:46] <Loetmichel> the manufactuerer has called back... "no problem, come in tomorrow moring and i'll tig that lapes for you!"
[11:19:51] <Loetmichel> <- relieved
[11:20:01] <MrHindsight> but still a cutting tool makes all those plunges for all those holes
[11:20:59] <Loetmichel> MrHindsight: no lager tools on a chinese 6040
[11:21:35] <Loetmichel> that machien is at its max capacity with 3,175mm mill bit and 0,2mm dept into aluminium
[11:22:00] <Loetmichel> its not rigid enough for lager tools
[11:23:28] <MrHindsight> yes, all the ones I've tried can't handle much without twisting
[11:24:25] <MrHindsight> if the gantries were steel it would make a world of difference
[11:24:56] <MrHindsight> the cost would even be lower to manufacture
[11:25:39] <pcw_home> with a nice brown oxide finish...
[11:26:10] <MrHindsight> 4 rectangles out of 1/2" ... yes with red oxide finish (already primed)
[11:34:30] <ubu-_> MrHindsight: please help me
[11:40:32] <ubu-_> do I install camunits?
[11:41:42] <MrHindsight> https://code.google.com/p/camunits/wiki/DownloadingAndInstalling
[11:43:42] <ubu-_> thanks I look it. try to night. and back tomorrow. thanks all
[11:43:43] <MrHindsight> but there are conflicts between what psha has as a package and the camunits build
[11:43:53] <ubu-_> you are very kind
[11:44:38] <ReadError> anyone here cut carbon/kevlar sheets?
[11:44:43] <MrHindsight> remember that when you get the bill
[11:47:43] <Jymmm> MrHindsight: Insert credit Card Here --> [ ]
[11:48:27] <humble_sea_bass> REad, I have
[11:50:29] <ReadError> humble_sea_bass, hows it cut?
[11:50:35] <ReadError> edge finish wise
[11:50:44] <ReadError> imagine the kevlar is rough on endmills?
[11:51:11] <humble_sea_bass> you cut it with scissors which will go dull near instantly
[11:51:33] <ReadError> nah these are layed up sheets
[11:51:46] <ReadError> carbon/kevlar verneer w/ a carbon substrate
[11:52:00] <humble_sea_bass> i was doing layups, unless it is embeded in a matrix of epxy you're just not gonna do anything in a mill
[11:53:10] <humble_sea_bass> your edge finish will most likely be terrible
[11:53:55] <ReadError> yea its like a carbonfiber sheet style
[11:54:02] <ReadError> so epoxy yea
[11:57:33] <humble_sea_bass> use an engraving bit and make sure you don't breathe it in
[11:57:50] <humble_sea_bass> also, throughly cleanup after
[11:59:52] <ReadError> ive done a fair amount of CF
[12:00:00] <ReadError> just never anything with a kevlar layup
[12:14:44] <Loetmichel> ReadError: i do occasionally
[12:15:31] <ReadError> how are your results?
[12:16:03] <Loetmichel> usung spiral toothed diamond dust clad TC bits: very well
[12:16:36] <Loetmichel> and for the thinner sheets and the fabric: use a ceramic blade scissor ;-)
[12:19:58] <ReadError> I mostly use those 'diamond burr' style ones

[12:37:11] <IchGuckLive> hi all B)
[12:37:36] <IchGuckLive> its a miss here try almost since last year
[12:38:18] <IchGuckLive> Loetmichel: how long did the flashlightr delivery tahe its not here yet
[12:49:36] <ReadError> MrHindsight, heres some of my projects http://www.dailygusta.com/Phone/
[12:52:51] <MrHindsight> I'm working on composites that can be printed rapidly. Those are perfect examples of SLA carbon fiber/epoxy applications.
[12:53:21] <MrHindsight> then you don't need fasteners
[12:54:27] <MrHindsight> except to fasten to motors or other parts, but you can print complete composites vs have to fasten them together
[12:58:59] * JT-Shop thinks out loud and wonders if there is a way to run a 5i25/7i76/7i76 config without the hardware?
[13:00:12] <JT-Shop> I guess you could make a hal file to create the pins and comment out the hostmot2 part...

[13:20:19] <XXCoder> well it looks cool but dunno
[13:20:40] <MrHindsight> the laminate will work fine
[13:21:23] <MrHindsight> it's just that they went to parker or similar for a quote on the machine
[13:21:47] <archivist> just posh plywood :)
[13:22:47] <MrHindsight> combine that with resin and it could make carbon fiber aircraft parts
[13:23:36] <_methods> shhh don't give them any ideas
[13:24:00] <_methods> they might make something useful
[13:24:25] <XXCoder> theres new type of 3d printer too., it actually prints in 3d and not layers
[13:25:00] <_methods> yeah i saw that
[13:25:05] <MrHindsight> and for plywood furniture they could just have a cam program setup cuts for 1/2" thick material that just gets pinned and glued together
[13:25:12] <XXCoder> combine that with carbon fiber
[13:25:19] <XXCoder> you can make tough 3d stuff
[13:25:33] <MrHindsight> XXCoder: which one is this?
[13:25:48] <_methods> they're still workin on it
[13:25:54] <_methods> i don'tthink its finished
[13:26:07] <XXCoder> yeah. cant find link
[13:26:17] <_methods> it's all in the pathing
[13:26:27] <MrHindsight> does it extrude?

[13:26:47] <XXCoder> only cnc and all
[13:26:50] <_methods> it does like 3d surfacing toolpaths while extruding
[13:26:56] <MrHindsight> yeah, not really new
[13:27:00] <_methods> no
[13:27:12] <XXCoder> not new, just new combination of tech
[13:27:36] <MrHindsight> most of this is 10-20 years old
[13:27:54] <MrHindsight> the real work is in the materials
[13:28:16] <XXCoder> I saw one that uses carbon fibver material but it was crappy
[13:28:18] <MrHindsight> plus you can't combine tech in the west thats under patent
[13:28:23] <XXCoder> maybve someone will do it better
[13:29:20] <MrHindsight> so if you take FDM and then use DLP the DLP patent holder won't share and say you're infringing
[13:30:11] <MrHindsight> thats why the whole http://americamakes.us/ is such a joke
[13:30:31] <XXCoder> too bad

[14:54:50] <IchGuckLive> im off BYE
[14:56:00] <bertrik> I have a few (possibly newbie-ish) questions
[14:56:19] <MrHindsight> just ask
[14:56:31] <bertrik> At the hackerspace, we have a plan to use an xz-table to do computer-controlled plasma-cutting
[14:57:14] <bertrik> G-code would be the language of choice for the interface between PC cutting application and the cutting-table, right?
[14:57:51] <MrHindsight> if using Linuxcnc to control it
[14:58:15] <bertrik> Looking at the wikipedia page for g-code, I see there's a huge list of g-codes. Is there some way to only implement a subset and still have it work?
[14:58:29] <MrHindsight> if you were hacking a plotter it might be excellon format gerber
[14:58:41] <MrHindsight> you just use the g-codes that you need
[14:58:46] <MrHindsight> if using linuxcnc
[14:59:17] <bertrik> Suppose we use linuxcnc to control it, what minimum set of g-codes should we support in the cutter?
[14:59:40] <MrHindsight> like having 103 keys on a keyboard, you just use the ones you want
[15:00:17] <MrHindsight> linuxcnc supports them all, if your g-code had only 1 code it will still work
[15:01:12] <bertrik> Hm, ok, maybe I don't fully understand what linuxcnc does exactly
[15:01:53] <MrHindsight> it will control all the motion and IO's but it only does what you send it in G-code
[15:02:35] <MrHindsight> http://linuxcnc.org/docs/html/gcode/overview.html
[15:03:16] <MrHindsight> G-code will have the tool paths and timing for when the cutter is ON/OFF
[15:03:33] <MrHindsight> Linuxcnc does nothing without that input
[15:03:50] <MrHindsight> so think of Linuxcnc like your inkjet printer
[15:04:00] <MrHindsight> and G-code is the file you want to print
[15:04:12] <bertrik> Oh sorry, my misunderstanding was that I thought that linuxcnc generated g-code, but it *accepts* g-code
[15:04:18] <MrHindsight> yes
[15:04:32] <MrHindsight> you can manually write g-code or use CAM
[15:05:37] <MrHindsight> http://opencam.sourceforge.net/ is an example
[15:06:25] <MrHindsight> http://openscam.com/
[15:06:44] <bertrik> thanks
[15:10:56] <bertrik> What's the cheapest/simplest kind of adapter that linuxcnc can use to (for example) send a PWM signal to a motor driver?
[15:11:25] <jdh> parallel port
[15:11:35] <MrHindsight> a built in LPT on a mainboard
[15:12:23] <MrHindsight> PCI to LPT cards are $15 and up, PCIe $25 and up
[15:12:35] <bertrik> wow, those (LPTs) are hard to find probably :)
[15:12:48] <MrHindsight> older boards had them built in
[15:12:50] <jdh> I just bought a bunch of PCIe ones for some hardware dongles.
[15:13:31] <MrHindsight> you just need to avoid the mediatek boards
[15:14:03] <MrHindsight> if you are going to use EPP with an FPGA
[15:15:28] <jdh> if you are going to buy a pci card, you might as well get a 5i25
[15:15:36] <bertrik> Would you think it is doable/fast enough to write a program on a microcontroller to accept g-code and control a motor?
[15:15:52] <jdh> it's been done
[15:16:00] <MrHindsight> heh, like reprap
[15:16:09] <bertrik> yes, a bit like that
[15:16:33] <bertrik> I'm probably underestimating motion control a bit here :)
[15:16:58] <MrHindsight> or just load/install from a CD, edit a config and start cutting
[15:17:13] <MrHindsight> they did as well :)
[15:17:35] <jdh> what problem are you trying to solve
[15:18:10] <cradek> jdh: you sound like me
[15:18:34] <bertrik> jdh: we want to create a computer-controlled plasma cutter, out of an existing xz-table and a plasma cutter torch
[15:18:51] <jdh> cradek: I had added a <cradek> to that but removed it.
[15:18:55] <cradek> haha
[15:19:17] <MrHindsight> bertrik: stepper motors?
[15:19:28] <jdh> bertrik: you can boot a livecd and start cutting, or screw around trying to make some uC work.
[15:20:14] <bertrik> MrHindsight: no, but I don't know exactly what kind of motors it has yet. It has a very crude on/off controller right now
[15:20:24] <MrHindsight> I'm actually a bit intrigued by why someone would want to go the uC route
[15:20:40] <cradek> MrHindsight: NIH syndrome
[15:20:50] <bertrik> if it fits, why not?
[15:20:52] <jdh> it seems to be fairly common
[15:21:17] <jdh> lots of times it seems people just want to find a use for a uC
[15:21:22] <MrHindsight> bertrik: time is of little value, like to write code for fun
[15:21:38] <jdh> "but I only want to do x" or "we only need it to y"
[15:21:39] <bertrik> yes
[15:22:16] <MrHindsight> why not use that energy to solve real problems
[15:22:25] <bertrik> and uC is easier to make real-time than a desktop operating system
[15:22:49] <bertrik> MrHindsight: it's also a learning experience
[15:22:54] <cradek> but that work is done
[15:23:09] <bertrik> I'm not insisting on a microcontroller
[15:25:28] <jdh> see grbl(?) and other avr based ones.
[15:35:01] <FinboySlick> Interesting new take on the singing CNC: https://www.youtube.com/watch?v=CAPS3vvSdV8
[15:36:36] <MrHindsight> I'd rather do that as a plugin for Linuxcnc than write an app for a uC
[15:38:48] <MrHindsight> http://www.computerworld.com/s/article/9247857/Consumers_are_meh_about_3D_printers no kidding
[15:39:55] <MrHindsight> useful consumer printers are years off, it's going to take years to get all the industrial applications working well

[18:58:46] <malcom2073> I have a ballscrew based 3d printer, and it can run up to 100mm/second. I'm having issues with 3d printer firmware, so I want to run linuxcnc if it can do what I need. 3d printers use only G1 movement commands, and I need it to ssmoothly slow down in corners, and smoothly accelerate back up to perimieter speed on straights, is that fairly reasonable to expect from linuxcnc?
[18:59:02] <malcom2073> I have very limited linuxcnc experience, mainly just running it on a mill, not really configuring or getting into the guts of it
[19:01:57] <LatheBuilder> malcom2073 do your gcode files have lots of short moves?
[19:02:07] <malcom2073> LatheBuilder: yeah :/
[19:04:09] <LatheBuilder> I'm new, so can't give you an answer but I've been lurking reading the mailing list for an embarassing amount of time. I understand there is an improved trajectory planner in the works for a later release. That said, try it out and see if the current release is objectionable. For that matter if you have a cnc mill running lcnc, try a hand edited print file on it?
[19:05:01] <malcom2073> LatheBuilder: Not yet, my next step was to give the gcode a try on the full size mill, but I'd have to convert all the feed rates down because the mill can't move nearly as fast as the printer.
[19:05:35] <LatheBuilder> maybe a simple box program with radiused corners. Fewer lines to edit...
[19:05:44] <malcom2073> Ah yeah true
[19:06:11] <LatheBuilder> or rather, arcs converted to line segments.
[19:06:40] <malcom2073> Right, I can use one "layer" of the 3d printer code from a simple box with radiused corners
[19:07:41] <LatheBuilder> whereabouts are you?
[19:07:56] <malcom2073> Southern PA
[19:08:21] <malcom2073> USA
[19:09:13] <LatheBuilder> I'm in Omaha NE. also usa. working through my first retrofit now
[19:09:49] <LatheBuilder> does your mill suit your purposes?
[19:10:09] <malcom2073> Ah cool. The big mill I have access to is my dads, we stripped out the stock control system because it was from the 90's, and have it running on emc2 now
[19:11:59] <malcom2073> I'd really like an excuse to use a G540 + beaglebone black to control my printer :-D So if linuxcnc can do what I need, it'd be awesome to convert over to that
[19:12:06] <LatheBuilder> sounds familiar, mine had the same vintage control on it. It gave up the ghost a few years back and it didn't seem usefull to put 1500 repairing it only to have it break again.
[19:12:40] <malcom2073> Yeah heh. His started "losing" parameters halfway through an operation, which isn't bad, unless one of those parameters reverses one of the axis directions :/
[19:12:47] <LatheBuilder> there are several guys playing with bbb's including several devs, and, I believe, the release manager.
[19:12:55] <LatheBuilder> ouch
[19:13:20] <malcom2073> yeah, I've talked with a couple guys who are doing work with it to get it up and running decently
[19:16:07] <LatheBuilder> out of curiosity, why need to use a bbb instead of a small form facter pc? Purely cost?
[19:16:21] <LatheBuilder> or replace need with want
[19:17:30] <LatheBuilder> be back later
[19:17:46] <malcom2073> Mainly want :)
[19:22:50] <MrHindsight> LatheBuilder: I think it started out as a search for a lower cost alternative
[19:23:20] <MrHindsight> the problem with the BBB is the poor gpu so it's mainly good for headless applications
[19:50:40] <XXCoder> finally bouht bunch of wires. gonna wire up to test system soon
[19:51:07] <XXCoder> whats best way to safely offset controller circuit so it dont just lay on wood though?
[19:53:57] <MrHindsight> use standoffs
[19:54:06] <XXCoder> where buy that?
[19:54:19] <MrHindsight> XXCoder: where are you/ US ?
[19:54:25] <XXCoder> washington state
[19:54:49] <MrHindsight> ahh Mouser, Digikey or make your own
[19:55:06] <MrHindsight> do your boards have mounting holes?
[19:55:20] <XXCoder> I guess plastic thick tube would do if correct size.
[19:55:28] <XXCoder> yeah 4 of em
[19:55:32] <MrHindsight> small machine screws and nylon washers and spaces etc
[19:55:38] <MrHindsight> spacers
[19:55:48] <XXCoder> excellent. thanks
[19:56:03] <XXCoder> I'll just mount on wood for now while I test system
[19:56:06] <MrHindsight> just be sure the conductive fasteners don't touch any traces
[19:56:14] <XXCoder> ok
[19:56:49] <MrHindsight> so nylon washers or even just nylon machine screws for temp
[19:57:50] <XXCoder> that'll work.
[20:07:33] <uw> hello
[20:07:55] <uw> user pcw?
[20:08:14] <uw> do you remember the band of the song "flags"
[20:08:29] <uw> you had posted it a while ago but i cant remember the ban
[20:08:30] <uw> d
[20:34:07] <malcom2073> LatheBuilder: I got some test gcode that clearly shows the problem now, and I know how it operates on my printer, so I should be able to give it a shot on linuxcnc and if it runs smoothly, then Iknow that's the way to go :)
[20:52:22] <pcw_home> uw: Blurt (Ted Milton)
[20:52:41] <Noxz> anybody here offering (to make?) couplers?
[20:52:49] <Noxz> rigid
[20:53:11] <Noxz> china messed up the sizing yet again
[20:58:48] <MrHindsight> Noxz: what size do you need?
[21:02:32] <Noxz> I need to measure the china ball screws to vierfy what their specs said.. but.. I beleive, 10mm -> 12.7mm (1/2")
[21:14:09] <MrHindsight> I started getting 6.35mm and i finish them myself
[21:14:52] <Noxz> I might just ream/drill the one side out bigger
[21:15:14] <Noxz> but, these are the 'jaw' kind, and I would much prefer rigid
[21:15:36] <MrHindsight> maybe for the time being until you find the ones you want
[21:15:56] <Noxz> or untill I make my own..
[21:16:00] <Noxz> it takes a cnc to build a cnc
[21:18:14] <XXCoder> nah
[21:18:19] <XXCoder> cnc makes iteasy
[21:18:55] <XXCoder> I plan to make fairly strongly boxed gantry type cnc so its rigid enough to in least slowly mill alum
[21:19:02] <XXCoder> so I can make improved cnc
[21:19:33] <Noxz> I need to do aluminium aswell
[21:20:08] <Noxz> but I dont plan on making the cnc all over.. make enough for 5 axis, but beyond that.. then onto my original project in mind
[21:20:28] <XXCoder> cool. I plan 3 axis
[21:21:01] <Noxz> my controller does 5, and I have 10 steppers... soo... I need another controller ;)
[21:21:12] <XXCoder> 10 axis? heh
[21:21:47] <Noxz> not all on one machine ;)
[21:21:54] <Noxz> well.. maybe
[21:22:00] <XXCoder> I think largest number I ever found was 23 axis for one machine
[21:22:07] <XXCoder> it was wire bender
[21:22:17] <Noxz> yup, that is one of my machines I need...
[21:22:24] <Noxz> except I plan on doing a Cam system
[21:22:25] <XXCoder> I think 12 was largest for non-wire
[21:22:29] <Noxz> so, 5 should be plenty
[21:23:46] <uw> thanks PCW
[21:24:16] <XXCoder> one of possibilities I want to do but probably wont is 8020 lathe project
[21:24:53] <Noxz> I was thinking about 80/20, untill I read their shipping is more expensive to the west coast... but even so.. what would be my alternative?
[21:25:10] <Noxz> as long as it's precise I can justify the money (shipping)
[21:25:16] <XXCoder> yeah shipping is bad :( amazon shipping isnt as bad
[21:25:20] <malcom2073> misumi-usa has decent extrusion
[21:25:23] <XXCoder> prime free even for some of em
[21:25:28] <malcom2073> their shipping is bad too though
[21:25:29] <MrHindsight> Noxz: where are you roughly?
[21:25:54] <Noxz> Silicon Valley
[21:26:01] <Noxz> Bay area, california
[21:26:05] <XXCoder> 8020 can be picked up at seattle right?
[21:26:28] <XXCoder> if so if I ever get money to upgrade and if I really love having a nice cnc, I would build a upgrade
[21:26:30] <MrHindsight> aren't there industrial supply stores that stock t-slot?
[21:26:40] <XXCoder> I dont know how to find em
[21:26:42] <Noxz> iunno
[21:27:01] <Noxz> yeah, it's so easy to look through 80/20 (well, sort of, they only use ebay stores)
[21:28:40] <Noxz> I got convined to try a epoxy+granite base as well
[21:28:46] <Noxz> convinced
[21:28:55] <XXCoder> I do want try make stuff with epoxy
[21:28:59] <MrHindsight> whats a nearby zipcode?
[21:29:15] <Noxz> mine is 95126
[21:29:36] <Noxz> for a ~4'x3' tabletop I am looking at ~$450 before shipping
[21:30:01] <MrHindsight> http://www.gawirth.net http://www.stevenengineering.com http://www.tecopneumatic.com
[21:30:22] <Noxz> I've been told about stevenengineering before
[21:32:49] <MrHindsight> http://www.tslots.com/contact-us Futura is out of Utah
[21:33:40] <MrHindsight> http://www.norcalsystem.com/ in Milpitas
[21:34:05] <Noxz> milipitas is 10mi fro me.. hrrm
[21:34:34] <MrHindsight> http://www.tslots.com/download-catalog
[21:34:44] <Noxz> doesnt look like they offer just 80/20 standalone
[21:35:10] <MrHindsight> http://www.tslots.com/student-support it's a different co called Futura they extrude in Utah
[21:40:55] <MrHindsight> Noxz: call them, they are listed as a disti
[21:43:03] <Noxz> looks like simply requesting for a quote is going to be the easiest
[21:43:15] <Noxz> I gotta sketch everything out ;)
[21:44:11] <Noxz> I have most sketched out.. but.. the joining plates etc are what I'm missing
[21:44:21] <MrHindsight> do you have a miter saw?
[21:44:51] <MrHindsight> they charge like $1 per cut
[21:45:28] <Noxz> most of the pecies I want will be 4' lengths
[21:45:35] <Noxz> and, if they can do it more accurate
[21:45:56] <Noxz> I don't have time/want to cut 100 peices to length myself
[21:51:31] <humble_sea_bass> you think they are going to be more accurate?
[21:51:48] <humble_sea_bass> give or take a 1/16 probably
[22:46:25] <humble_sea_bass> https://www.youtube.com/watch?v=uL6e3co4Qqc
[23:10:53] <MrHindsight> tiny linear motors
[23:13:15] <humble_sea_bass> they just look fun
[23:13:19] <humble_sea_bass> like slot racers
[23:13:31] <MrHindsight> they should make a toy version
[23:15:52] <MrHindsight> http://www.youtube.com/watch?v=I4DHfNtZGts&amp;lr=1
[23:16:05] <MrHindsight> Wall-Climbing Robot
[23:16:37] <humble_sea_bass> thanks geckos
[23:17:00] <MrHindsight> http://www.sri.com/engage/products-solutions/electroadhesion
[23:18:57] <MrHindsight> http://www.youtube.com/watch?v=WC8XtH9i7qk bigger version
[23:22:34] <MrHindsight> clamping pressures in the range of 0.5 to 1.5 N per square cm of clamp (0.8 to 2.3 pounds per square inch)
[23:22:49] <MrHindsight> power (on the order of 20 microwatts/Newton weight held)
[23:24:22] <MrHindsight> they combine it with the electroactive polymers
[23:29:08] <MrHindsight> http://www.grabitinc.com/news-videos.php
[23:30:09] <humble_sea_bass> the cardboard box handling video is the best one
[23:30:23] <humble_sea_bass> with the electro adhesive conveyor belt
[23:34:47] <MrHindsight> they don't seem to be doing much with it
[23:35:05] <MrHindsight> I wonder if their prices are too high
[23:35:05] <humble_sea_bass> picking up stationary
[23:35:37] <MrHindsight> no real design wins for the grippers or the muscle
[23:36:50] <humble_sea_bass> joe blow would be happy with a vaccuum probably
[23:37:38] <MrHindsight> probably just military applications
[23:39:30] <MrHindsight> the funding probably doesn't allow for any small scale applications
[23:41:18] <MrHindsight> Nike’s investment was part of Grabit’s $3 million Series A round on Monday
[23:42:39] <humble_sea_bass> they probably see a payoff for manufacturing those newage skintight running/swimming suits
[23:42:48] <humble_sea_bass> those things are just panels
[23:42:49] <MrHindsight> 40mW of power will be able to allow 11 square feet of an electroadhesive to be able to support 440lbs
[23:43:13] <MrHindsight> 40 lbs per sq ft
[23:43:17] <humble_sea_bass> that's kind of brutal
[23:43:47] <MrHindsight> 4.4oz per sq inch
[23:44:10] <MrHindsight> whats one atmosphere?
[23:44:47] <MrHindsight> 14.6
[23:45:23] <MrHindsight> so it's about 1/3 that of a vacuum gripper
[23:45:29] <MrHindsight> now i see why
[23:46:47] <MrHindsight> so I'd need 5 sq ft of glove to climb a wall :)
[23:46:54] <MrHindsight> on each hand
[23:47:20] <MrHindsight> so Spiderman Paddles vs gloves
[23:49:44] <MrHindsight> the minibots are more practical
[23:51:35] <MrHindsight> I've only seen two at a time being controlled, not sure if they are moving randomly or through planned/controlled paths
[23:51:57] <MrHindsight> all the groups were moving in synch
[23:52:39] <humble_sea_bass> i think it is a path
[23:52:47] <humble_sea_bass> literally like a slot car
[23:54:04] <MrHindsight> might be more like a 2d linear motor
[23:54:22] <MrHindsight> but they can turn them off/on individually
