[00:11:05] <Crom> I want to build a bench like my pops.. 2x4's bolted together with 3/8 all thread, legs are 4x4's tenon'd together with a 2x4 cross bar tenon'd into the front and rear leg
[00:13:18] <Crom> 12' long with the front 3' section with 1/2" cold rolled on top by the garage door for welding on.
[01:15:04] <XXCoder> http://www.marshalltool.com/cgi/CGP2SRIM?PMITEM=PM71DD750X&PARTPG=CGP2LMXE&PAMENU=&PAHDID=000000140029461&PARDID=735727727755777
[01:15:07] <XXCoder> interesting
[01:15:13] <XXCoder> I wonder how effective this is.
[01:15:33] <XXCoder> and it seems to be only drills. what do people use for endmills for example
[01:16:45] <roycroft> an expensive tool grinder
[01:18:18] <XXCoder> got example link?
[01:50:28] <toastydeath> XXCoder, not very effective
[01:50:53] <toastydeath> i can grind drills better by hand than those machines
[01:51:16] <XXCoder> interesting
[01:52:50] <toastydeath> generally, on larger drills you want to split the point or put multiple relief angles on it
[01:52:59] <toastydeath> and even with constant relief it's not very good
[01:53:35] <toastydeath> i am often changing the point geometry on drills in the shop to run them faster/harder in a given material
[01:54:28] <XXCoder> col :)
[01:54:30] <toastydeath> when i have used drill-doctor style machines they often have no relief
[01:54:31] <XXCoder> *cool
[01:54:38] <toastydeath> or do it wrong
[01:54:52] <archivist> or offset one side to adjust size they drill
[01:54:53] <XXCoder> $9 for 123 blocks at marshall. weird
[01:55:10] <XXCoder> too bad 246, ones I want, is always expensive lol
[01:55:51] <toastydeath> 123 blocks are a great scraping project
[01:56:29] <XXCoder> I was supposed to make 123 blocks as part of internshi[
[01:56:31] <XXCoder> never happened
[01:56:42] <toastydeath> if you've got a surface grinder they go pretty fast
[01:57:24] <toastydeath> my shop always made our own rather than buy them
[01:57:24] <XXCoder> cool, though not I nor shop I work at have one
[01:57:39] <toastydeath> mill + scraper is just as good/better
[01:57:53] <XXCoder> shop I interned at had one, but it was still being installed when I got job
[01:57:57] <toastydeath> though getting them orthonormal in general takes a good understanding of setting up angular measure
[01:58:47] <XXCoder> meaning all 3 pairs of oppositing sides is parallel to each other?
[01:59:29] <toastydeath> perpendicular, yes
[01:59:51] <XXCoder> cool
[02:00:09] <XXCoder> wondering if this is worth it
http://www.marshalltool.com/cgi/CGP2SRIM?PMITEM=NA5552432444&PARTPG=CGP2LMCD&PAMENU=&PAHDID=000000140029461&PARDID=735727727755777
[02:00:25] <XXCoder> pretty good sale
[02:00:35] <archivist> parallel is easy, right angle less easy
[02:01:11] <XXCoder> http://www.marshalltool.com/cgi/CGP2SRIM?PMITEM=NE60ES4&PARTPG=CGP2LMXE&PAMENU=&PAHDID=000000140029461&PARDID=735727727755777
[02:01:16] <XXCoder> this is cheaper but dunno
[02:01:32] <toastydeath> i wouldn't get either, but the first link would make an okay beater set
[02:02:48] <toastydeath> i'd rather have one good 8" square
[02:03:23] <archivist> square too big is a pain
[02:03:59] <XXCoder> thats why I am thinking 2, 4 and 6 inches ones is fine
[02:04:16] <archivist> I often find squares not ideal for the job
[02:04:50] <XXCoder> first one I linked to has max error of .0006" which isnt bad
[02:05:02] <archivist> I have a 3", 12" and a mini set 1-2"
[02:05:04] <XXCoder> second one is... blank
[02:05:10] <toastydeath> it's usually per inch
[02:05:21] <toastydeath> they just don't say that in the copy
[02:05:35] <XXCoder> Squareness of the blade edge to the working face of stock is .0006
[02:05:44] <XXCoder> not too clear if its max overall or per inch
[02:05:46] <toastydeath> yeah, that's per inch in squares and level
[02:05:54] <toastydeath> and it's almost never checked in QC
[02:06:24] <XXCoder> .0036" max if its 6 incher
[02:08:07] <toastydeath> a master square is also a good project for scraping, similar to a 123 but only has three faces finished
[02:08:08] <archivist> 3 thou would be terrible
[02:08:45] <XXCoder> it depends on how precise I need it to be
[02:08:52] <XXCoder> though not too sure what I need
[02:08:59] <XXCoder> so probably not buying it for now
[02:10:33] <XXCoder> SH30093 - End Mill Item num. DF104070700D MFG num. 40707-00-D << no picture either, dude how am I supposed to know what size it is :P
[02:12:50] <archivist> a good starter can be an old wooden tool chest and contents
http://www.ebay.co.uk/itm/Job-Lot-Engineers-Tools-Plus-Drill-And-Wooden-Chest-/172280289448
[02:14:08] <archivist> somewhat variable in quality and condition, can have fun restoring and making good
[02:14:17] <XXCoder> I guess so
[02:20:46] <Deejay> moin
[02:23:25] <Crom> hmm K40 laser cutter in the US free shipp $318
[02:26:26] <archivist> cutting paper?
[02:33:43] <archivist> a review
http://www.electricstuff.co.uk/lasercutter.html
[02:33:45] <Deejay> cutting air ;)
[02:33:50] <XXCoder> cutting space itself
[02:36:20] <XXCoder> thats actually better review than other one I read
[02:36:36] <XXCoder> other one guy had to pracially rebuild machine as parts fell out
[02:53:52] <XXCoder> problem with chinese products is you might get a ripoff which is fine, or ripoff of ripoff which might not be fine
[03:09:47] <archivist> hmm cant find the set of squares for sale I got many years ago, it comes complete with a straight/knife edge
[03:17:38] <XXCoder> perfect for machinist assassin ;)
[03:18:02] <XXCoder> why was one edge sharp though?
[03:20:08] <plpower> morning from germany
[03:20:18] <XXCoder> hey pluspower
[03:20:50] <plpower> do i need a new swap as LCNC is on 12.04 in a external partition while i try to install wheezy
[03:21:12] <plpower> or simply logical root
[03:21:28] <plpower> auto installer will go for that version
[03:21:36] <plpower> but i do not trust this
[03:21:49] <plpower> better to part with gparted
[03:22:06] <plpower> new external swap and root
[03:22:35] <plpower> is a secondf swap on the disk alowed anyway
[03:24:13] <XXCoder> if I recall swap is just swap, any linux based os can use it, though I'm pretty sure not at same time
[03:25:20] <plpower> ok need to ask on debian i think
[03:47:32] <archivist> XXCoder,
http://www.collection.archivist.info/searchv13.php?searchstr=squares
[03:48:04] <XXCoder> sharp edges
[03:48:08] <XXCoder> interesting indeed
[03:49:17] <archivist> reload that search, updated the text
[03:52:12] <mase-tech> Hi peps
[03:52:25] <XXCoder> hey
[03:52:41] <mase-tech> My educational cnc is ready
[03:52:55] <mase-tech> yesterday I was able to draw a picture :D
[03:53:02] <mase-tech> I am very happy
[03:53:09] <mase-tech> There are things to tweak
[03:53:17] <mase-tech> but it is looking very good
[03:53:50] <XXCoder> got pics?
[03:54:41] <mase-tech> I am drive it with arduino, but next step is to take a pc with breakoutboard better motorstepperdriver and stronger steppers
[03:54:56] <archivist> pics or it didnt happen :)
[03:54:59] <mase-tech> On the pc i will install linux cnc
[03:55:06] <mase-tech> :D
[03:55:16] <mase-tech> I promise to show pictures tomorrow
[03:55:33] <archivist> with linuxcnc you dont need aaaaaarguiNO
[03:56:17] <mase-tech> yes as I told I want to replace the arduino with a linux cnc machine
[03:56:30] <mase-tech> but I have a question
[03:56:47] <mase-tech> linux cnc is very nice as far as I can see
[03:57:04] <mase-tech> but are there good CAMs for linux available
[03:57:45] <archivist> best cam for cnc is insiderearofskullcam
[03:57:46] <mase-tech> friends are using fusion or estlcam. which leads to win and mach3
[03:58:04] <XXCoder> mase-tech: just use windows for cam side
[03:58:12] <archivist> people are using fusion with linuxcnc
[03:58:19] <XXCoder> you can use another computer for cam
[04:00:12] <mase-tech> thats a solution i guess
[04:02:11] <mase-tech> I found a makerspace which I am very active in
[04:03:13] <mase-tech> we have a china cnc like
http://www.ebay.de/itm/CNC-Router-Graviermaschine-Engraver-3040-4-Achs-MACH3-Frasmaschine-3D-printer-/281949208170?hash=item41a57b7e6a:g:Hu4AAOSwNuxXYhly
[04:03:41] <mase-tech> I plan to drive it with linux cnc
[04:03:59] <mase-tech> but this is a teaser
[04:15:04] <Deejay> archivist, ha, just got this yesterday:
http://quadrokopter.net/fraese/messzeugsatz/messzeugsatz2.jpg
[04:15:33] <XXCoder> not too sure what use is those sharp edged angles?
[04:23:20] <archivist> Deejay, looks like a later version of the same thing, with added DIN spec
[04:25:38] <archivist> mine are not stainless, tiny bit of rust on the smallest
[04:26:02] <Deejay> i am not sure if I ever need those ;)
[04:26:23] <Deejay> true precise for me ;)
[04:26:30] <Deejay> *too precise
[04:26:53] <Deejay> but nice to have ;)
[04:26:59] <archivist> I hardly ever use mine either :)
[04:27:50] <archivist> searched for the logo on mine this morning and not found it, no idea who made my set
[04:29:26] <Deejay> hehe
[04:33:18] <archivist> I think many tools just get opened and tested and put away again
[04:35:47] <Deejay> indeed
[04:36:54] <XXCoder> owwww
https://www.youtube.com/watch?v=axjmK_vjYCM
[04:37:19] <XXCoder> good thing that guy walked away
[04:46:57] <archivist> the one underneath was further away than you think
[04:47:21] <XXCoder> yeah though that guy would probably have been hurt or died
[04:47:31] <XXCoder> walking that close to load
[04:48:27] <archivist> nah looked about 15-20 ft below therefore also some distance back from it (on a floor/level below)
[04:49:06] <XXCoder> possible, angles and distances can get tricky woth camera
[04:49:35] <archivist> during privatisation there were many open days at local power stations
[04:50:12] <XXCoder> saw another guy, saw idiot filming himself making stupid mistake with manual mill
[04:50:22] <XXCoder> first he loses hat to running spindle
[04:50:30] <XXCoder> then he makes mistake confusing X and Y
[04:50:32] <XXCoder> uhhgh
[04:50:50] <XXCoder> I have confused + and - directions for given axis but never wrong axis
[05:02:46] <jthornton> morning
[05:20:22] <jthornton> https://www.youtube.com/watch?v=G4-lUNa0CpY
[05:29:45] <XXCoder> and yes offsets is important heh
[05:29:49] <XXCoder> so are tool settings
[05:30:14] <XXCoder> I once drilled a part and into fixture using ball em because someone changed it and forgot to change it back
[05:30:36] <jthornton> I was just learning how to use the lathe lol
[05:31:20] <XXCoder> honestly largest mistake I did as professal machinist (not intern) was forgetting to change tool back from chuck to tool #1. that machine does not check
[05:31:30] <XXCoder> so it bashed chuck into fixture
[05:31:39] <XXCoder> $750 CAT50 chuck scrapped
[05:31:40] <jthornton> this is what I expected to film
https://www.youtube.com/watch?v=isTD6bDF_LI
[05:32:02] <XXCoder> you forgot to walk it in heh
[05:32:21] <XXCoder> I always do when its not standard unload clean load cycle
[05:32:36] <XXCoder> ABS?
[05:32:43] <jthornton> delrin
[05:32:49] <XXCoder> unknown to me
[05:33:47] <XXCoder> I have bunch of nylon pucks dunno what I can do with em
[05:34:08] <XXCoder> with current spindle its too hard to cut lol (no coolant no air)
[05:34:36] <archivist> naughty using the parting tool to pull the bar out
[05:34:49] <jthornton> http://www.mcmaster.com/#8576k17/=13f3puk
[05:35:16] <XXCoder> archivist: why its bad?
[05:35:19] <jthornton> I'm open for suggestions on how to pull it out
[05:35:29] <XXCoder> lathes at work use "the claw"
[05:35:37] <XXCoder> dunno what would be aviliable for you
[05:35:49] <archivist> machines I used had a bar feed with a weight
[05:35:59] <XXCoder> actually couple that does not have claw use bar feeder
[05:36:31] <DaViruz> i thought it was rather clever
[05:36:32] <archivist> and a stop in one tool position
[05:36:47] <XXCoder> jthornton: other way is it places the stop and stops spinning, looses collet and m0 wait for you to manually move it to stop
[05:37:12] <XXCoder> though cutout tool move is cool i think heh
[05:38:42] <jthornton> I've done the put a stop out there and wait but I make these by the hundreds
[05:39:12] <jthornton> what does a "claw" look like
[05:39:30] <archivist> the bar tube has a slot and a pusher on the old capstans
[05:40:14] <XXCoder> basically a claw heh but I think its actuated by lathe tool side so I dont think yours would work
[05:40:23] <archivist> cant see the weights in this pic but can see the tubes
http://www.collection.archivist.info/archive/DJCPD/PD/2008/2008_10_07_Richards_of_Burton_clockworks/P1010200.JPG
[05:40:31] <XXCoder> it is 4 pronged and closes on bar stock
[05:40:54] <XXCoder> jthornton: sorry about little vague, I'm mill operator not lathe operator
[05:41:48] <archivist> similar too
http://www.lathes.co.uk/emwee/img0.jpg
[05:42:04] <XXCoder> http://www.royalproducts.com/img/product/upload/Grippex20LBP.jpg
[05:42:24] <jthornton> oh I see the weight now
[05:43:09] <XXCoder> interesting
[05:43:40] <jthornton> so position a stop, open collet, material moves out, close collet and turn
[05:43:49] <archivist> yup very fast
[05:44:14] <XXCoder> probably even faster than cnc bar feed
[05:44:18] <XXCoder> or the claw
[05:44:26] <archivist> I am a poor sod that spent time on a capstan.....
[05:44:57] <jthornton> what is pushing on the bar stock does it rotate or what?
[05:45:52] <archivist> there is a plug in the tube with an ear through the slot
[05:46:24] <XXCoder> btw "claw" is actually named cnc bar puller
[05:46:32] <XXCoder> there is few variants
[05:46:34] <archivist> plug has an internal V for the bar to centralise it....a bit rattles
[05:47:33] <jthornton> https://www.youtube.com/watch?v=SgACQ3PvM1o
[05:47:53] <XXCoder> https://www.youtube.com/watch?v=CTp8Cu1z9o4 interesting variant
[05:48:13] <XXCoder> limited to one size though
[05:52:35] <jthornton> I could make one of those I suppose looks easy enough
[05:52:57] <XXCoder> one you linked to or one of links I linked to?
[05:53:34] <jthornton> that tube one you linked to
[05:53:49] <XXCoder> ah yeah that'd be perfect to match to job
[05:54:30] <XXCoder> I suppose just turn a hollow area with slight hollow inside to make grippers, then mill tube into fingers
[05:55:53] <archivist> only a small diameter range, the other perhaps a bit better
[05:56:23] <XXCoder> archivist: yeah that simple design is better suited to match to job, and he did say he makes a LOT of those plastic thingies
[06:05:58] <jthornton> http://d2n4wb9orp1vta.cloudfront.net/resources/images/cdn/cms/royalbarpuller1b.jpg
[06:06:45] <XXCoder> interesting
[06:08:45] <jthornton> http://cdn.mscdirect.com/global/images/ProductImages/0338858-23.jpg
[06:12:13] <archivist> cnc turn the pullers and put them on your site...profit
[06:12:51] <jthornton> I'd bet they are heat treated and I don't have an oven for that yet
[06:13:17] <archivist> can you sub that out?
[06:13:18] <XXCoder> ypour parts are plastic you probably can make pullers from plastic
[06:13:23] <XXCoder> no heat treatment needed
[06:13:48] <jthornton> I was thinking about aluminum or steel puller
[06:14:16] <jthornton> kinda like the one that mounts next to the parting tool, saves a spot on the turret
[06:14:43] <XXCoder> that'd work yeah, and one more tool slot is a bonus
[06:16:44] <jthornton> but the one that goes over the bar might be easier and faster to make and just turn the other end down far enough to fit in my collet holder
[06:20:52] <XXCoder> most designs have pros and cons
[06:29:58] <XXCoder> hey
[07:02:33] <Tom_itx> jthornton, quite common on bar machines
http://www.pmpa.org/docs/reference/changing-collets-and-pushers.pdf?sfvrsn=0
[07:04:41] <Tom_itx> a feed stop inside the machine would stop it at the right length
[07:08:00] <jthornton> looks complicated to me
[07:13:59] <archivist> the other difference is with a pusher and sensible tube size you can control whip of the bar
[07:14:43] <XXCoder> whip of bar? I guess curved and stuff?
[07:16:09] <archivist> there is a lot of noise at some speeds with the bar hitting the tube wall
[07:18:08] <archivist> there is a danger with a puller that you could pull to a short end that the collet cannot grip properly, the pusher cannot do that, it stops at the rear of the collet
[07:18:59] <jthornton> I'm standing there deburring and packing them so no problem there
[08:05:33] <Oussama> d
[08:06:32] <Oussama> how can i build a new interface for linuxcnc
[08:07:07] <jthornton> start with gscreen
[08:07:15] <jthornton> or build from scratch
[08:07:33] <jthornton> http://gnipsel.com/linuxcnc/gui/index.html
[08:10:58] <XXCoder> nice link
[08:11:54] <Oussama> ok thanks , and how can i install linuxcnc on ubuntu 14.04 LTS
[08:12:41] <jthornton> http://linuxcnc.org/docs/2.7/html/getting-started/getting-linuxcnc.html
[08:18:08] <Oussama> thank you good link
[08:55:38] <Teckel> Hello !
[08:56:04] <Teckel> I've a question about LinuxCNC...
[08:58:33] <Teckel> Is there anyone ?
[08:58:51] <XXCoder> yeah
[08:58:55] <XXCoder> ask your question.
[08:59:00] <Teckel> Oh cool
[08:59:16] <XXCoder> I thought you was typing a long question
[08:59:31] <Teckel> Is possible to connect an USB CNC machine to LinuxCNC, instead of parralel interface ?
[09:00:07] <XXCoder> there is issues with usb, but I suppose? not expert here
[09:00:53] <Teckel> the machine inquestion is a CNC 6040Z and it has ony an USB interface...
[09:01:19] <Teckel> I fear it may be used only with the Mach 3 software on Windows
[09:01:39] <Teckel> Because of the USB interface...
[09:01:58] <XXCoder> something like
https://sc02.alicdn.com/kf/UT8xziGXkRaXXagOFbXK/200401017/UT8xziGXkRaXXagOFbXK.jpg ?
[09:02:11] <jthornton> Teckel: no
[09:02:50] <Teckel> yes that's it
[09:04:00] <XXCoder> well the way I understand it usb is usually not good because of latency
[09:04:09] <XXCoder> but then it may be different dunno
[09:05:21] <Teckel> but on the linuxcnc wizard, i've found only the parallel way to connect any machine...
[09:05:30] <Teckel> nothing about usb
[09:06:31] <archivist> Teckel, remove the control motion connect a bob to a pc parallel then direct to stepper drivers in the control
[09:06:56] <archivist> usb has latency problems
[09:07:57] <Teckel> okay
[09:08:44] <Teckel> i'm not sure to understand your solution with a "bob" ... ? Can you explain more ?
[09:09:02] <Teckel> (sorry for my little english, I usually speak french...)
[09:09:08] <Teckel> :-)
[09:09:25] <archivist> break out board
http://www.ebay.co.uk/itm/321905519866
[09:10:28] <archivist> the bob provides isolation and drives the step dir inputs on the stepper drivers in the control
[09:11:41] <archivist> not all bob cards are created equal :)
[09:11:45] <Teckel> okay. so if I understand just, the schema of connection is: CNC router (usb) -> bob (usb) > bob (parallel) > computer (parallel) ?
[09:12:25] <archivist> no
[09:12:40] <archivist> no usb at all
[09:13:04] <archivist> the usb on that bob is a power input not a signal
[09:13:17] <Teckel> okay
[09:13:59] <Teckel> so this card must control directly the controllers of router, with bypassing usb controller ?
[09:14:27] <archivist> the stepper drivers of the control
[09:14:50] <archivist> yes bypass the usb controller
[09:15:00] <Teckel> ok.
[09:15:48] <archivist> I presume you are currently using mach3?
[09:17:13] <Teckel> no, I have not tried yet, because waiting a part from transporter
[09:17:36] <Teckel> but to make a first test, I will certainly try with mach3 on Win xp
[09:17:47] <Teckel> have you experience about mach3 ?
[09:18:01] <Teckel> is it "usable" ?
[09:18:09] <archivist> just hear stories about it
[09:18:22] <sel> don't try to talk about windows here, archivist will scold you
[09:19:18] <archivist> only if you "sell" it
[09:19:31] <Teckel> okay no problem, normal !
[09:20:06] <Teckel> the goal for me is to finally use linuxcnc
[09:20:12] <Teckel> very good reputation
[09:20:16] <Teckel> stability, etc...
[09:20:31] <sel> I'm not going to sell my machine
[09:20:55] <archivist> sell = promote windows and mach3
[09:20:56] <Teckel> yep
[09:22:30] <Teckel> so, for finishig discussion, for using CNC 6040z on linuxcnc, I must buy a Breakout board and modify the CNC 6040 case to connect it directily to the breakout card, and with parallel to the PC ?
[09:22:31] <Teckel> just ?
[09:23:17] <archivist> something like that yes
[09:23:30] <Teckel> okay
[09:24:29] <archivist> when I see 6040 I am not aware of what the controller has
[09:25:08] <Teckel> so i will testing the machine on mach3 and the parallel port will be a good upgrade later...
[09:25:41] <sel> ok archivist, but I said my software was proprietary never said it was mach3 :-)
[09:26:01] <Teckel> I will take informations about wich breakout board will "match" with 6040
[09:27:40] <archivist> that one I showed (available from many places) is used by a number of us without problems
[09:28:29] <archivist> not all 6040 have a full control anyway some I just looked at have parallel port input
[09:28:38] <Teckel> okay it's good to know, thank you
[09:29:38] <archivist> do you have a link to the 5040z you are getting
[09:31:22] <archivist> this is parallel, not usb
http://www.ly-cnc.com/product/CNC_6040Z-S80_Router__4axis_Engraver-en.html
[09:32:01] <archivist> should just work after configuring linuxcnc
[09:42:46] <Teckel> the 6040Z I have is only usb...
[09:44:17] <Teckel> like this:
http://www.china-cncrouter.com/upfile/a_0/20160418194525432.jpg
[09:47:14] <malcom2073> Ifyou're unlucky, they use an all-in-one control board inside. If you're lucky, you can detach the USB microcontroller part, and hook linuxcnc direct up to the stepper drivers via a breakout board
[09:50:19] <archivist> if single card cut the tracks between micro and stepper driver chips, some electronics knowledge required
[09:51:32] <Teckel> okay I see
[09:51:40] <Teckel> Thank you very much
[10:23:47] <tiwake> I want a desktop Power8 computer
[10:25:21] <tiwake> woah, thats cheap
[10:27:03] <tiwake> herm
[10:28:05] <tiwake> I'd still rather have one of AMD's ARM computers
[13:15:36] <Erant> pcw_home: For some reason my 7i78 setup has started acting up recently. I was suddenly losing steps on one of the axes, and now it seems as if the direction signal's being intermittently de-asserted. I checked all the wiring, and while doing that I noticed U6 was getting hot. U5 is fine. Did the differential transceiver fail?
[13:21:01] <pcw_home> The 7I78 has a inverting and a non inverting buffer ( U6 is a 74HCT541 or 74ACT541)
[13:21:03] <pcw_home> Sounds like a damaged chip
[13:21:31] <Erant> k, I'll see if replacing it helps.
[13:23:39] <pcw_home> Make sure you dont tie any outputs to 5V or ground ( don't laugh we've seen people do this to unused differential pair pins )
[13:23:56] <Erant> Heh. Yeah, no.
[13:24:36] <Erant> I buzzed all of the pairs out to GND, each other, etc. etc. No shorts.
[13:25:17] <pcw_home> warm CMOS buffer chip with no load says bad chip
[13:25:47] <Erant> It's easy to replace and test. I've ruled everything else out.
[13:26:11] <dioz> does kerf depend on cutter? how hard is a x-y table to build?
[13:26:43] <Erant> kerf depends on a shitton of things.
[13:26:55] <archivist> kerf depends on cutter and quality of spindle (how true it runs)
[13:27:37] <archivist> cutting load and machine flex adds an error term
[13:27:38] <Erant> archivist: What about deflection? (though I guess that's partly down to the cutter)
[13:27:45] <Erant> Right
[13:28:09] <archivist> but that would generally be an offset cut
[13:28:16] <dioz> well.. i guess a x-y gantry. for upto 4' x 4' sheet metal.
[13:28:32] <dioz> 14 gauge would be the thickest
[13:28:43] <archivist> laser/plasma?
[13:29:18] <dioz> i'd end up getting a extension for my plasma cutter and fabricating a bracket to hold the gun
[13:29:34] <Erant> pcw_home: What's the package on those buffer chips?
[13:29:46] <pcw_home> TSSOP
[13:30:09] <Erant> Do I want a 100 of them for $2.50...
[13:30:44] <CaptHindsight> yes for spares :)
[13:31:58] <archivist> dioz, you may get directional kerf variation if a nozzle is damaged
[13:32:05] <CaptHindsight> whats the smallest 8b or 16b micro in die form? Who has the smallest die?
[13:32:43] <dioz> archivist. replace consumables. i think a majority of it comes down to speed and tip size
[13:32:54] <dioz> is my logic anyways
[13:33:01] <archivist> worrying about the die...premature optimisation :)
[13:33:49] <dioz> show me links to diy gantry systems. what motors or servos are typical? any hydrolic rigs?
[13:34:15] <CaptHindsight> archivist: 8bit micros don't use really small gate geometries like 32b
[13:34:39] <archivist> not aware of links to hydraulic servos and cnc and linuxcnc
[13:35:04] <CaptHindsight> if they did I figure you could have die <3um square
[13:35:43] <archivist> I think IO pads will start limiting
[13:35:54] <dioz> i can come by lots of hydraulic stuff... on the low low
[13:36:18] <CaptHindsight> archivist: the whole thing would have to be <6um in diameter
[13:36:48] <Erant> Your bond pads start dominating at some point.
[13:37:02] <archivist> does anybody make any die that small
[13:37:05] <CaptHindsight> it would not have a bond pads
[13:37:17] <CaptHindsight> archivist: what I'm wondering
[13:37:20] <archivist> no bond=no IO
[13:37:27] <Erant> Though the smallest micro we've made at work that I'm aware of... Sec.
[13:37:51] <CaptHindsight> if I did it with organic semiconductors then it could be rolled up or folded
[13:38:38] <CaptHindsight> yes, no IO it's stand alone, it would be more of a SOC
[13:38:50] <CaptHindsight> the size of a red blood cell
[13:39:20] <archivist> it is still talking to something/getting power from
[13:39:37] <Erant> 1.25 mm^2
[13:39:56] <CaptHindsight> yeah enormous
[13:40:09] <archivist> more like I expected
[13:40:22] <Erant> That's at 130nm feature size
[13:40:48] <CaptHindsight> how many gates?
[13:40:52] <Erant> Majority goes into digital logic, 83K gates. (0.44 mm^2)
[13:40:59] <CaptHindsight> oh big
[13:41:13] <Erant> Then EEPROM is 16x256b at 0.33m^2
[13:41:54] <Erant> ROM, RAM is the rest.
[13:42:49] <Erant> But they get an insane amount of them out of a single 12" wafer.
[13:44:55] <archivist> when I were a lad they this much on a wafer
http://www.collection.archivist.info/archive/Lucas/PS/PB7B/ps2282.jpg
[13:45:21] <CaptHindsight> I'm just running the numbers on silicon vs organic semiconductor processors vs using actual neurons to build nanoscale devices
[13:45:47] <archivist> for scale
http://www.collection.archivist.info/archive/Lucas/PS/PB7B/ps2281.jpg
[13:45:54] <CaptHindsight> not really a whole lot of R&D out there on practical designs
[13:51:29] <CaptHindsight> how to power silicon gates from glucose?
[13:52:12] <CaptHindsight> is silicon just not practical?
[13:52:29] <CaptHindsight> are organic semiconductors any better?
[14:03:06] <dioz> so what you guys are telling me is no one has any diy/homemade instructions for a x-y gantry?
[14:03:35] <archivist> there are many gantry designs on the web
[14:03:38] <CaptHindsight> NAND and NOR gates for 14nm FinFet avg power = 87nW x 20k gates = 1.74mW
[14:04:42] <Erant> archivist: If I remember correctly, they were getting somewhere between 20 000 - 40 000 chips out of a wafer.
[14:04:52] <CaptHindsight> Erant: how much power does that chip draw at lower speeds say <1Mhz?
[14:05:01] <dioz> so last night i was falling asleep on the couch and 3 times the gf woke me up. so i threw a little water at her with made her move all my bedding to the hallways. so i pretended to throw hers on the front lawn and really i put it on the couch. so she took a bunch of my computer hardware and put it outside
[14:05:12] <archivist> Erant, rather more than the 1960s :)
[14:05:49] <dioz> so i hid her purse and credit cards. then i gave her back her credit cards and made it so she couldn't get her car out of the garage and i hid her cellphone
[14:06:00] <dioz> odds are i'm going home to divorce papers
[14:06:11] <dioz> so i wanna build a big x-y gantry
[14:06:40] <Erant> CaptHindsight: It was a peak-load type chip (it was actually an authentication chip doing ECDSA) so I'm not sure if I can find the numbers easily.
[14:06:43] <Erant> It was very little though
[14:07:34] <Frank_13> guys, im going nuts trying to figure out which is the best combination of timing belts and pulleys for me, so much information and stuff
[14:08:01] <Frank_13> im trying to make a reduction drive for a cnc router
[14:08:24] <dioz> archivist. gimme, on your opinion, the best one...
[14:08:47] <Frank_13> what pitch should i choose? does it matter the GT2 or GT or whatever spec?,
[14:08:59] <Erant> dioz: That Old Tony has a really good video on making a proper one.
[14:09:16] <Erant> Well, several.
[14:09:35] <Erant> (In fact, all his videos are well worth watching.)
[14:09:36] <Erant> https://www.youtube.com/user/featony
[14:09:40] <dioz> thnx. basically i'm pretty much a master fabricator... but there's no point in reinventing the wheel
[14:09:44] <dioz> you feel me?
[14:09:45] <Frank_13> i dont have any machine to make them
[14:09:58] <Erant> Frank_13: I picked the cheap ones.
[14:09:59] <Erant> :)
[14:10:39] <Frank_13> ok, what are you moving?
[14:10:48] <Erant> Z axis
[14:11:03] <Erant> Fairly light machine, 200W servos.
[14:11:07] <archivist> dioz, I dont have a gantry, best depends on function
[14:11:10] <Frank_13> im moving 150kg
[14:11:12] <Frank_13> heh
[14:11:17] <Frank_13> 2 servos 1kw each
[14:11:20] <Frank_13> for X axis
[14:12:17] <Erant> Oh snap. Yeah, ignore the cheap recommendation :)
[14:12:24] <Erant> There should be spec sheets for 'm though.
[14:12:56] <Frank_13> yeah im checking on the mechmate forum to see what they used
[14:13:29] <archivist> dioz, Frank_13 here is in the middle of building one
[14:13:51] <CaptHindsight> Erant: just wondering
[14:14:20] <Erant> It was low mW for sure. Either single or low double digit.
[14:15:42] <Frank_13> only if i could find a pic..
[14:15:51] <Erant> Atmel fabbed it, fairly impressed with them.
[14:16:18] <dioz> 150kg's. holy
[14:16:23] <Erant> ST too. NXP not so much :/
[14:16:32] <Frank_13> 150kg the gantry
[14:17:09] <dioz> tbh i don't know the terms... are the rails part of the gantry?
[14:17:13] <CaptHindsight> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?GantryPlasmaMachine belt driven
[14:17:35] <dioz> thnx capt
[14:17:53] <CaptHindsight> just swap for ballscrews
[14:18:00] <dioz> btw hindsight is usuly 20/20
[14:18:03] <dioz> jfyi
[14:19:10] <dioz> idk what material to build with. i'm thinking some kknd of laminate
[14:19:22] <dioz> unless i need the steels
[14:19:30] <CaptHindsight> steel laminate
[14:19:43] <CaptHindsight> steel and polymer granite
[14:19:46] <archivist> fire and water, metal
[14:19:56] <Frank_13> but ur building a router a mill a plasma? what
[14:20:44] <CaptHindsight> you can have rails on the gantry for the z axis and rails for the gantry that it rides on
[14:20:57] <dioz> what do they call the axis that moves the router bit up and down?
[14:20:58] <CaptHindsight> on the X or Y
[14:21:05] <CaptHindsight> Z axis
[14:21:35] <dioz> is there a z axis with plasma? probably only to "pull the trigger" ?
[14:21:55] <Frank_13> to adjust the height, in a plasma machine thats very important
[14:21:59] <CaptHindsight> http://s151.photobucket.com/user/wachuko/media/Garage/cnc_machine_axes_zpsdgdl9hsa.png.html
[14:22:08] <archivist> torch height control
[14:22:32] <dioz> i'd do that manually.
[14:22:40] <dioz> with snakes and ladders
[14:22:44] <dioz> tbh
[14:23:14] <dioz> consumables arent consistant through their lifetime
[14:23:18] <dioz> if you feel me
[14:23:20] <archivist> dioz, here is another with linuxcnc
http://gnipsel.com/shop/plasma/plasma-gallery.xhtml
[14:23:28] <dioz> yes!!!!
[14:23:40] <dioz> this is why i ask cause you guys know...
[14:23:54] <dioz> just point me over yonder and i'll go
[14:23:58] <archivist> the plate warps so most do it automatically
[14:24:05] <Frank_13> ur consumables will last 5x times or more if you have a torch height control
[14:24:08] <CaptHindsight> http://www.cnczone.com/forums/diy-cnc-router-table-machines/74145-cnc.html
[14:24:39] <CaptHindsight> http://www.cnczone.com/forums/diy-cnc-router-table-machines/168692-cnc.html

[14:25:26] <dioz> i'm down for manual torch height control
[14:25:27] <CaptHindsight> http://www.cnczone.com/forums/diy-cnc-router-table-machines/117609-cnc.html
[14:25:47] <CaptHindsight> use the Google
[14:26:56] <dioz> i lol cause my first year apprenticeship books say that a plasma cutter is supposed to start a cut with 45 degrees before going straight down.
[14:27:44] <dioz> idk why . it don't say.
[14:27:49] <dioz> i assume safety
[14:28:54] <dioz> to avoid blow back and sparks in the face
[14:29:07] <Tom_itx> keep your head outta the way
[14:29:24] <Frank_13> if i remember correctly the thc goes up a bit when firing up then gets to the recommended or setted height paramter for cutting
[14:29:29] <Tom_itx> they're likely talking about manual plasma cutters
[14:30:23] <dioz> manually cutting yes. we weren't allowed to use guides and had to maintain distance 1/16 inch away from metal manually
[14:30:48] <dioz> i said "this id the dumbest shit in the world"
[14:30:54] <CaptHindsight> avoid plasma cutting any type of container that contains combustible fluids!
[14:30:57] <archivist> the cnc thc measures the voltage to keep it constant
[14:31:06] <dioz> then iwrecked the tip
[14:31:08] <CaptHindsight> do not plasma cut C4
[14:32:04] <dioz> i seen a youtube video about milling rebar
[14:32:05] <CaptHindsight> avoid using or handling fireworks near your plasma cutter
[14:32:23] <dioz> so i tried it. i thought it would chatter. it is possible
[14:32:50] <archivist> avoid using a plasma or laser in a wooden building
[14:33:52] <Tom_itx> or hay barn
[14:34:21] <archivist> hay.....oops been there done that
[14:34:23] <CaptHindsight> do not store, handle or manufacture explosives while operating a plasma or laser cutter
[14:34:50] <Tom_itx> only exception to that is on the 4th of July
[14:34:59] <archivist> was using a gas axe :)
[14:35:15] <CaptHindsight> obvious legal disclaimers now required to be included with all plasma cutters
[14:35:31] <dioz> i don't get it
[14:35:38] <dioz> u callin me dumb?
[14:36:01] <dioz> i'm a motherfucking ddos king
[14:36:02] <CaptHindsight> just making fun of what would be required in the USA
[14:36:31] <archivist> and I HAVE set fire to hay
[14:36:31] <gregcnc> eh you'd still get sued
[14:37:13] <archivist> one regular in here HAS burnt his house down
[14:37:26] <CaptHindsight> forgot about that
[14:37:53] <CaptHindsight> left his laser on and walked out of the room for 1 minute
[14:38:07] <dioz> oh i'm not a yank. not offended anymore
[14:38:34] <Tom_itx> does ddos make you smarter than the rest?
[14:38:54] <Tom_itx> and i don't think you are, rucas is
[14:39:18] <dioz> ddos means i have more to prove i think
[14:39:27] <dioz> based on the fact i have a small penis
[14:39:39] <dioz> but w/e
[14:40:27] <dioz> btw your links are spot on
[14:51:40] <Frank_13> lol
[15:06:53] <dioz> what is considered a big table?
[15:08:00] <dioz> what sizes do sheet metal usually come in? i think i should know that
[15:08:54] <Duc> what thickness of metal
[15:09:11] <Duc> usually plates come in 4x8 but some places have 5x10
[15:09:35] <dioz> max 14 gauge
[15:09:39] <dioz> mild steel
[15:09:39] <JT-Shop> you can get much bigger than 5' x 10'
[15:10:39] <Tom_itx> think shipyard
[15:12:00] <Tom_itx> http://www.tmtco.com/products/plates-steel-sizes.html
[15:12:07] <Duc> true but most fab shop would receive only 5x10
[15:12:43] <Tom_itx> 96" x 12'
[15:12:49] <dioz> rolls
[15:12:59] <dioz> is wat they usually get
[15:13:08] <dioz> with a hydraulik sheer
[15:13:17] <dioz> blankin the fuck out
[15:13:31] <dioz> or a laser cutter
[15:17:39] <Duc> either way most home tables or small business tables are 4x4, 4x8 or 5x10 in size
[15:18:39] <dioz> archivist: in the table is there usually water?
[15:18:59] <dioz> wouldn't that be messy?
[15:19:27] <Duc> nah the water takes up a crap load of the dust from plasma cutting unless you have a downdraft table
[15:19:40] <Duc> I happen to have a 5x5 water table at home
[15:19:47] <dioz> that gnipsel rig you linked
[15:19:54] <dioz> holy fuck does that unit ever look overkill
[15:20:07] <dioz> the whole portion that holds the cutter just seems about a billion times too big
[15:20:09] <Tom_itx> he tends to do things right
[15:20:37] <archivist> dioz, you want really big
http://www.collection.archivist.info/archive/mirror/cnc/Travelling_Gantry_Machine.pdf
[15:20:37] <dioz> http://gnipsel.com/shop/plasma/images/plasma-19.jpg
[15:21:12] <dioz> archivist: i seen huge the other day. i was at a kramer repair facility installing their duct and they had a 6 ton gantry crane
[15:21:20] <Duc> that Z axis looks overkill
[15:21:32] <archivist> 6 ton is little
[15:22:10] <archivist> that PDF is a 250 ton gantry
[15:22:22] <Duc> I was thinking the plasma one. the gantry mill is cool to see that size in person
[15:22:55] <dioz> i think i'll make it out of laminate wood for starters
[15:23:19] <Duc> go 80/20 for the gantry for a plasma
[15:23:24] <archivist> wood and plasma does not seem sensible
[15:24:09] <dioz> archivist: i will eventually machine pieces accordingly
[15:24:16] <dioz> but wood is easier to start with
[15:24:27] <dioz> the rails will be metal though
[15:24:28] <archivist> it burns
[15:24:30] <Duc> now days there is some really good kits out there
[15:24:35] <archivist> plasma is hot
[15:24:37] <dioz> Duc: how much?
[15:25:08] <dioz> archivist: the table will be a grid table with consumable slats
[15:25:17] <dioz> but the rails and runners will be wood
[15:25:22] <dioz> they won't touch the hot
[15:26:11] <dioz> i just see wood being cheaper and easier to get it all down and functioning
[15:26:44] <Duc> dioz: trying to find the link but MC on pirate4x4 makes a good kit
[15:26:48] <dioz> making parts on either the mill or the lathe takes a while
[15:26:56] <archivist> I use wood for book shelves and hand work bench legs
[15:27:38] <Duc> and for electronics I would recommmend Candcnc hands down the best for home
[15:28:10] <dioz> i have lots of hydraulics
[15:28:26] <dioz> looking at ways to measure movement
[15:29:01] <Duc> not sure hydrualics would have the speed you need for the table
[15:29:25] <dioz> fare enough
[15:30:09] <dioz> in that case i'll have as much to worry about wood as i do rubber pullies and plastic gears/cams
[15:31:36] <dioz> roper whitney bead roller just came up on kijiji
[15:31:50] <dioz> i called.. busy... busy. busy... finally it isn't busy
[15:31:52] <dioz> and they already sold it
[15:31:56] <dioz> it was on there for 2 minuteds
[15:32:00] <Duc> stepper motors and gear drive on a rack works well
[15:32:02] <dioz> TWO MINUTES
[15:34:02] <dioz> Duc: idk if i like the idea of the motor being moved back and forth... seems like more weight on the frame
[15:34:17] <dioz> i mean it could just be grams we're talking about
[15:34:36] <dioz> what do i know
[15:36:10] <dioz> and when i think of top of the line drifter chassis for rc-cars
[15:36:15] <dioz> i think belt driven
[15:36:47] <dioz> maybe completely unrelated
[15:37:28] <Duc> alot of people have the motors on the gantry. I have dual y motors and the z axis is driven across the table with one z motor. 620oz units
[15:38:34] <dioz> 21 grams in a ounce?
[15:39:06] <jdh> remind me to not buy drugs from you
[15:39:10] <dioz> ;]
[15:39:39] <dioz> 7 grams in a quarter
[15:39:53] <dioz> 3.5 grams in a 1/8th
[15:40:30] <Duc> I have no clue
[15:40:33] <dioz> and a gram is $10
[15:41:29] <dioz> or $80 depends what you're getting
[15:43:36] <Duc> almost have ac in the garage. found a 22,000 BTU portable unit for 250.
[15:44:16] <dioz> nice!
[15:45:17] <dioz> you spend a lot of time out there in the heat of the day?
[15:45:34] <dioz> you live on the equator or something?
[15:49:20] <Duc> live in AL, USA
[15:49:33] <Duc> garage is stress relieve for me but not at 95 degrees
[15:51:19] <dioz> ah. yah i feel you
[15:52:22] <dioz> with all the motors being on the grantry itself i guess that reduces cable routage
[15:53:07] <dioz> could even route asingle overhead
[15:55:51] <Duc> I used IGUS cable tray to route one bundle onto the gantry
[15:57:05] <dioz> i could make cable tray if needed
[15:57:15] <dioz> i have access to unlimited sheet metal pretty much
[15:57:16] <dioz> for free
[16:00:12] <Duc> what is your budget for this
[16:00:51] <dioz> depends what i come up with for prices on step motors
[16:00:58] <dioz> or whatever the primary drivers are gonna be
[16:01:07] <dioz> the rest i can fabricate
[16:03:06] <Duc> this is what I was thinking about for the IGUS
http://www.ebay.com/itm/Igus-z-08-40-028-cable-track-chain-147-cm-/121877284734?hash=item1c6073c77e:g:CikAAOSwJb9WqOZH
[16:03:50] <Duc> is probably a $5,000-7,000 project
[16:04:44] <dioz> yah idk... hang a cable from a tree with a support spring
[16:04:49] <dioz> to prevent it from wobbling around
[16:05:14] <Duc> people have done that
[16:05:26] <Duc> plasma cam used to do something like that
[16:06:14] <dioz> the way i see it is... i'mma build it as cheap as i possibly can
[16:06:21] <dioz> cut all the corners
[16:06:23] <dioz> just to get it working
[16:08:20] <Duc> Eh, doesnt work out good that way
[16:08:41] <dioz> i'm pretty much a pro with wood
[16:08:43] <Duc> 14GA requires fast movement and that means rigid
[16:08:57] <Duc> setup to remove messy lines
[16:19:30] <dioz> well... what i'm basing my idea off
[16:19:36] <dioz> is a drafting table with a built in t-square
[16:22:11] <t12> can anyone translate?
http://imgur.com/a/eGlOs
[16:22:26] <t12> assuming 10ghzish power amp/generator?
[16:27:23] <synx508> Seems to have too many pins to be a dummy load/power meter
[16:51:33] <Roguish> hey. what's the best distro to start with for a JA system configuration? wheezy, jessie, mint, ????
[16:56:49] <JT-Shop> I like mint
[17:23:12] <FloppyDisk> does mint chocolate chip ice cream count?
[17:24:21] <Deejay> gn8
[18:24:31] <Jymmm> FloppyDisk: Absolutely
[18:30:44] <Jymmm> I have a (chinese?) thread (rack adj foot) that comes VERY close to 20 (.086) TPI per starrett thread pitch gauge. Is there a metric thread that comes close to that by chance?
[18:31:21] <Sync> 1.25mm
[18:32:03] <Jymmm> Metric threads confuse me, what does this mean: M2.2x0.25 ???
[18:32:42] <Jymmm> I know 1/4"-20 is 1/4 diameter and 20 TPI.
[18:34:10] <FloppyDisk> m6x1.0 is 6mm dia and 1 thread every 1 mm...
[18:34:30] <FloppyDisk> Your's is 2.2mm dia and a thread every 0.25mm
[18:35:03] <Jymmm> FloppyDisk: Ah, ty
[18:35:38] <FloppyDisk> The only difference (I could be wrong) is that SAE does it in Threads per incn (like you said), but divide 1/20 and you have the length of one thread.
[18:35:59] <FloppyDisk> The problem is that it would in some odd ball thousands of an inch and no-body would want to talk that way...
[18:36:21] <FloppyDisk> I'm full in on SAE, from the midwest originally, but I do like metric... Ugh..
[18:36:23] <Jymmm> heh
[18:37:02] <FloppyDisk> It makes sense in a lot of cases and easy to scale up or down... Plus, I could cut my wrench and socket inventory in half - hahahah.
[18:37:08] <Sync> FloppyDisk: describing it as 1 thread every 1mm is strange
[18:37:12] <Sync> just say the pitch is 1mm
[18:37:31] <FloppyDisk> You're right...
[18:38:36] <Jymmm> I know the thread is bigger than 1/4"-20, but smaller than 3/8"-16. I measured the outside threads and got .305" or 7.747mm
[18:39:08] <Jymmm> So, M8x1.25 ???
[18:40:26] <Sync> hm, unlikely with that diameter
[18:41:42] <Sync> or it could be a shitty screw
[18:41:50] <Sync> yeah, probably a regular M8 screw
[18:42:05] <Jymmm> It's a foot for shelving
[18:42:17] <Jymmm> adjustable for leveling
[18:42:45] <Sync> yeah, probably a regular m8 screw then
[18:44:23] <Sync> (regular, in the sense that it is the standard pitch)
[18:44:27] <Sync> which is 1.25mm
[18:44:54] <Sync> but you would not call it M8x1.25, you'd probably get yelled at here if you do in a drawing
[18:45:56] <Jymmm> Well, I mean in the hardware store looking for a nut to confirm
[18:46:09] <Jymmm> it looks to be a fine pitch
[18:47:23] <Jymmm> On this thread pitch gauge, it says "20 - .086", but I can't figure out what the .086 is?
[18:48:45] <Jymmm> It's an old version of this
http://www.starrett.com/metrology/product-detail/metrology/metrology-products/precision-measuring-tools/fixed-gage-standards/Screw-Pitch-Gages/6
[18:49:09] <Sync> in the hardware store I only get M8 screws
[18:53:50] <archivist> in metric screw threads you only mention the pitch if it is different to the usual coarse standard
[18:56:00] <Jymmm> Is 1.25 course or fine?
[18:56:26] * SpeedEvil turns the pitch dial to 'very fine' and gets a diamond screw.
[18:57:11] <Sync> Jymmm: it is the regular one.
[18:57:21] <Jymmm> Sync: k
[18:57:21] <Sync> which would be coarse
[18:57:36] <Jymmm> and fine would be?
[18:57:38] <Sync> (fine is not defined as a single pitch)
[18:57:52] <Jymmm> for M8 that is
[18:57:55] <Sync> yes
[18:58:03] <Sync> one fine would be 1mm
[18:58:09] <Jymmm> k
[18:58:23] <Sync> but there also is .75
[18:58:23] <Jymmm> ty
[18:58:39] <Sync> and .5 and .25
[18:59:21] <Sync> which are all DIN 13-2 or ISO 261 iirc
[19:00:32] <acmehendel> having trouble compiling linuxcnc I am getting an error around libreadline related to rs274
[19:11:52] <archivist> acmehendel, most important with a question like that is the actual error message
[23:04:29] <acmehendel> archivist where would I post the error message?
[23:08:31] <CaptHindsight> pastebin.com
[23:14:47] <acmehendel> Build error:
http://pastebin.com/ymrhVywz
[23:14:57] <acmehendel> Need help fixing this build error
[23:17:49] <CaptHindsight> your version of readline is most likely too old
[23:19:05] <CaptHindsight> Linuxcnc on Slackware!
[23:36:09] <acmehendel> What version should I get?
[23:36:15] <acmehendel> and how do I check the version I have now?
[23:37:40] <CaptHindsight> t12: looks like a Soviet era miniaturized cell phone amplifier :)
[23:37:57] <CaptHindsight> you should see the size of the cell phone!
[23:50:11] <t12> hah
[23:50:15] <t12> i wonder if i should crack it
[23:50:18] <t12> need translator first
[23:50:28] <XXCoder> crack what?
[23:50:45] <t12> that russian RF thinger
[23:52:43] <XXCoder> is it software?
