[08:01:31] <jthornton> er
[09:04:54] <WillenCMD> Morning
[09:06:50] <WillenCMD> Or afternoon depending on where you are i guess
[09:08:09] <jthornton> morning
[09:08:32] <jthornton> dang rain killed my internet last night
[09:08:56] <jthornton> ah the fun of having WildBlue satellite internet
[09:12:09] <Tom_itx> jthornton point it at mars and see what it's up to
[09:12:52] <jthornton> I don't think I want to move it...
[09:13:16] <Tom_itx> those models came in nicely
[09:13:29] <Tom_itx> but not all are good layouts for machining
[09:13:58] <jthornton> cool, I've always said I can design a part in SW that you can't make
[09:14:11] <Tom_itx> they were made to be printed
[09:14:26] <jthornton> 3-D printed?
[09:14:34] <Tom_itx> i thought the idea of printers was to test parts for production :)
[09:14:38] <Tom_itx> yes
[09:23:12] <Tom_itx> it's somewhat interesting comparing the 2 processes though
[09:26:07] <archivist> mid afternoon coffee break
[09:29:38] <L84Supper> jthornton, how do you handle downloading ISO's of Linux distros or even LinuxCNC over WildBlue?
[09:29:58] <L84Supper> don't they have a limit of 500MB/day or something similar?
[09:30:34] <jthornton> I don't think it is that low
[09:31:11] <jthornton> the usage meter is broken and they say if you use way way way too much we might throttle you back
[09:31:42] <jthornton> of course bad weather seems to throttle me enough LOL
[09:32:05] <L84Supper> sadly it's the same with ATT DSL
[09:32:30] <L84Supper> even with Comcast cable on real heavy days
[09:32:55] <archivist> I dont have a throttle, they just meter and sand abusive invoices for going over ones limit
[09:36:04] <L84Supper> http://www.hughesnet.com has the daily bandwidth cap
[09:37:09] <jthornton> they are nasty and mean, my unknowing neighbor got a $350 bill his first month
[09:37:27] <L84Supper> we seem to get throttled by every service, comcast, ATT, Clear etc
[09:37:42] <L84Supper> sometimes for a day sometimes a few days
[09:37:48] <r00t4rd3d> heh, and I get called out for off topic.
[09:38:08] <L84Supper> when trying to download LinuxCNC ISO's
[09:38:10] <L84Supper> :)
[09:38:44] <r00t4rd3d> no worries, that only pertains to me
[09:38:49] <jthornton> LOL
[09:39:12] <archivist> there are levels and amounts of off topic
[09:39:15] <jthornton> I'm working on a LinuxCNC tutorial
[09:39:51] <archivist> Im cleaning up the sliding head lath and dreaming of cncing it
[09:40:16] <archivist> found its first restoration date, 1965
[09:41:23] <Tom_itx> ww2 surplus?
[09:41:31] <jthornton> mhaberler seems to be busy today
[09:43:22] <archivist> Tom_itx, I think it dates from the early 1950's but not sure cannot read the importers/sellers badge where it is at the moment
[09:44:18] <L84Supper> QuickCutCNC.com NEW Interactive Quotes for CNC Machining...... I bet anything submitted will require some "consulting help" from them
[09:46:15] <archivist> hmm expensive but the right manual in the wrong country ebay 170429943375
[09:47:03] <archivist> I wonder if one gets an original or a copy
[09:47:59] <archivist> and neg feedback confirms, copies!
[10:54:41] <skunkworks__> http://www.youtube.com/watch?v=SVdr-WZTcpA
[11:03:09] <jthornton> very nice
[11:03:47] * jthornton needs a BLDC controller that will do odd things
[11:05:57] <skunkworks__> odd things?
[11:06:24] <Tom_itx> is that plexiglas?
[11:07:44] <Tom_itx> oh i see now :)
[11:07:46] <Tom_itx> nm
[11:07:57] <Tom_itx> the first angle looked transparent
[11:12:58] <jthornton> yea, spin to stall then reverse so many degrees
[11:14:04] <jthornton> then stop
[11:16:38] <skunkworks__> hal?
[11:19:24] <jthornton> something smaller like ardunio would be better
[11:31:23] <Tom_itx> jthornton an xmega would be better suited to do complex pwm etc
[11:33:24] <jthornton> like this? http://www.youtube.com/watch?v=gYRRcmjVmBg
[11:35:13] <tjb1> Hey jthornton, the square tubing is ASTM A500 Grade B
[11:35:19] <Tom_itx> probably so
[11:35:25] <jthornton> hey
[11:35:36] <Tom_itx> it is a 3.3v chip though
[11:41:06] <Tom_itx> and they're cheap
[11:41:47] <Tom_itx> jthornton, who did that one?
[11:42:16] <skunkworks__> http://www.youtube.com/watch?v=uZ4kAY96JfE
[11:42:19] <jthornton> dunno just a grroogle search
[12:01:55] <archivist> skunkworks__, is that guy using the right kind of tap!
[12:07:00] <skunkworks__> ?
[12:08:21] <archivist> the youtube link you pasted :)
[12:11:09] <skunkworks__> I like the spiral taps - but all have worked ok rigid tapping..
[12:11:53] <archivist> spiral is correct for rigid, his looked a bit like hand taps
[12:13:28] <archivist> I like spiral for hand use too :)
[12:16:56] <skunkworks__> yes
[12:21:38] <ScribbleJ> There are different kinds of taps?
[12:23:25] <syyl_> of course
[12:24:20] <syyl> for trough-holes, blind holes, that one for machine use, that for synchronous spindles, hand taps, tapping taps
[12:26:06] <skunkworks__> I have a couple of 10-32 spiral taps.. I guard them with my life. They are awesome for both rigid tapping and hand tapping
[13:16:08] <archivist> ScribbleJ, once you have used a spiral tap in anger you will never want hand taps again :)
[13:16:34] <ScribbleJ> When I retire hand taps from my collection, will I hire a bugler to play taps for them?
[13:16:57] <archivist> 4 slides freed up on the sliding head \0/
[13:18:32] <JT-Shop> archivist has visions of sugar plumbs and cnc controlled slides in his head now
[13:19:57] <archivist> considering how long it spent in the rain and since last use, it is beginning to slide/move like a very well made lathe
[13:21:08] <archivist> found a brochure on a forum for its later brother http://www.practicalmachinist.com/vb/general/bechler-10-lathe-243337/
[13:22:37] <ScribbleJ> http://www.youtube.com/watch?v=kWTlSaatOsA&feature=youtu.be
[13:25:38] <JT-Shop> interesting brochure
[13:25:43] <archivist> look at the cycle time http://www.youtube.com/watch?v=TDxvBHXklJo
[13:25:49] * JT-Shop knows how a swiss works now
[13:31:43] <archivist> gibs are interesting, they taper into the v not along the slide
[13:53:48] * mrsun is now an owner of a band cold saw =)
[13:53:57] <mrsun> one of those you can tilt up and use as a metal bandsaw =)
[14:06:16] <syyl> one of those chinese ones? :D
[14:06:24] <syyl> most important machine in my shop
[14:22:26] <syyl> random question: is it possible to add a Gxx code to linuxcnc, that, for example runs the code for a square pocket?
[14:22:44] <syyl> without c-knowledge
[14:24:31] <skunkworks__> o-words?
[14:28:37] <JT-Shop> syyl: you can in master or just make a subroutine
[14:29:01] <syyl> hmm
[14:29:06] <JT-Shop> http://linuxcnc.org/docs/html/gui/ngcgui.html#_db25_example
[14:29:40] <syyl> i wanted to avoid ngcgui ;)
[14:29:49] <syyl> my goal was just running it in the mdi
[14:30:12] <syyl> type Gxx (position) (size) (depth) etc
[14:31:10] <JT-Shop> o<square> [1][2][3] call
[14:31:31] <JT-Shop> http://linuxcnc.org/docs/html/gcode/o-code.html#_calling_files
[14:31:46] <JT-Shop> you can pass up to 30 parameters
[14:32:18] <syyl> i think, thats what i wanted :D
[14:32:28] <JT-Shop> there you go
[14:41:50] <syyl> tank you, JT-Shop
[14:41:58] <syyl> that will work for me \o/
[15:05:24] <JT-Shop> welcome
[15:20:19] <r00t4rd3d> I wish someone would hurry up and post No Easy Day ebook
[15:27:20] <L84Supper> "05:00 somewhere in the Indian Ocean. Seal Team 6 was glistening in man dew waiting for orders that would go down in history"
[15:42:03] <JT-Shop> hmmm I've hooked up my X encoder to the 7i77 but I don't see any encoder counts...
[15:43:02] <micges> got power?
[15:45:42] <alex_joni> got milk
[15:46:54] <JT-Shop> my guess is you actually have to have the wires in the correct places for it to work
[15:47:11] <alex_joni> heh
[15:49:20] <JT-Shop> yep I have confirmed that the wires must be connected to the correct places or you won't see your encoder counts
[15:50:44] <alex_joni> no wireless encoder counts?
[15:54:00] <JT-Shop> no counts without 5v
[15:54:16] <JT-Shop> index works :)
[15:56:59] <alex_joni> JT-Shop: cool
[15:59:03] <micges> alex_joni: have some new projects near cnc?
[15:59:45] <alex_joni> hmm.. not really
[16:00:01] <alex_joni> mostly bots :)
[16:09:14] <DJ9DJ> gn8
[16:10:19] <Jymmm> alex_joni: they're all bots in one form or another
[16:14:52] <alex_joni> right
[16:15:26] <alex_joni> now we could digress into a philosophical debate about how they feel and if they are alive
[16:16:09] <Jymmm> No we couldn't =)
[16:22:11] <Jymmm> alex_joni: At least not on IRC, in a pub sure =)
[16:26:29] <micges> hmm, beer, I need beer
[16:41:34] <r00t4rd3d> http://i.imgur.com/WHV2C.jpg
[17:47:56] * JT-Shop hands micges a cold home brew
[18:13:57] * r00t4rd3d twists up a fatty and passes it
[18:15:07] <andypugh> Interesting talk at Geek-camp. A chap has found 10,000 unsecured PLCs connected to the internet.
[18:15:47] <andypugh> (He was/is a researcher in computer security)
[18:16:10] <r00t4rd3d> are any in irans nuke facilities?
[18:16:27] <andypugh> Clearly that came up in conversation.
[18:16:37] <r00t4rd3d> really?
[18:17:37] <andypugh> Stuxnet was really specific though, whereas it spread widely, it only actually did anything bad when controling specific VFDs connected to specific PLCs in a specific IP address range.
[18:18:55] <andypugh> I was also rather impressed by the chap who can make a key for a lock in less than a minute. With the lock in-situ.
[18:20:44] <andypugh> Here he is in action: http://youtu.be/Bj9KEmLWRek
[18:20:47] <t12> theres amazing stuff sitting on the internet unpassworded
[18:20:55] <t12> lots of NMRs
[18:21:17] <JT-Shop> to answer your question there is no way to filter user names like you suggested
[18:22:03] <andypugh> Pity
[18:27:15] <JT-Shop> yes
[18:27:33] <andypugh> An interesting point was that MD5 authentication is client-side based. You can see the hash to match in the page source. Googling the hash will frequently return the plaintext.
[18:27:53] <JT-Shop> wild
[18:28:58] <r00t4rd3d> give up some hashes
[18:30:06] <JT-Shop> well X and Y encoders are connected and seem to work in the correct direction :)
[18:35:05] <t12> andy: context?
[18:39:39] <andypugh> t12: Getting into the web-interface of a SCADA system
[18:41:21] <t12> its not md5 c&r?
[18:41:43] <t12> oh or you mean
[18:41:46] <t12> its all in js or something
[18:41:53] <t12> both the request and auth
[18:42:41] <andypugh> That is what was said.
[18:44:21] <t12> heh
[18:46:44] <r00t4rd3d> Pretty sure thats a good felony charge.
[18:47:32] <r00t4rd3d> if you do it, cover your tracks
[18:51:22] <JT-Shop> BP knee mill conversion under way... XYZ encoders hooked up and scaled
[18:53:30] <JT-Shop> I love questions like this about craigslist items "Whats your bottom dollar on this"
[18:53:54] <JT-Shop> I respond "make me a decent offer"
[18:55:02] <JT-Shop> and you never hear back from them...
[18:56:42] <r00t4rd3d> i like when you get your CL title emailed to you with a ? at the end
[18:56:54] <r00t4rd3d> Custom Wood Signs?
[18:57:17] <JT-Shop> or "is it still for sale?" sdhfslen1234@gmail.com
[18:57:30] <r00t4rd3d> then I reply yeah? and get penis pill emails
[18:57:59] <JT-Shop> I never reply to emails from craigslist or text messages outside of my area code
[18:58:07] <r00t4rd3d> ive found if the sent from and the reply to address are different, dont bother, spammers.
[18:58:30] <JT-Shop> I do report every email if that does any good
[18:59:10] <JT-Shop> http://semo.craigslist.org/mcy/3215486930.html
[18:59:40] <r00t4rd3d> is that your stuff?
[18:59:55] <JT-Shop> yea, do you like the spammer notice?
[19:00:22] <r00t4rd3d> no i like the honda
[19:00:32] <r00t4rd3d> is that an old XR?
[19:00:57] <r00t4rd3d> ahh XL
[19:01:05] <JT-Shop> the red one yea it is an XL200R]

[19:06:05] <r00t4rd3d> xr250r
[19:06:06] <t12> anyone ever swap ball bearings for a ballscrew?
[19:06:21] <JT-Shop> later version of mine I assume
[19:06:33] <r00t4rd3d> yeah kinda
[19:06:44] <JT-Shop> I was looking for a xl250 when I found the xl200r
[19:07:13] <JT-Shop> I like the exhaust better on the xr
[19:07:49] <r00t4rd3d> mine is an 04
[19:08:11] <JT-Shop> mine is a '4
[19:08:18] <r00t4rd3d> sat in a garage for most of its life
[19:08:31] <r00t4rd3d> was bought for a wife and she never rode it, scared.
[19:08:59] <JT-Shop> best kind od deal to find
[19:09:11] * JT-Shop hears the dinner bell ringing
[19:09:18] <r00t4rd3d> i paid 1000 for it
[19:12:27] <r00t4rd3d> does your wife really ring a bell?
[19:13:06] <r00t4rd3d> http://www.rainymood.com/
[19:14:24] <r00t4rd3d> heh, i just scared my dog with that
[19:14:39] <r00t4rd3d> i think he is in the tub
[19:17:07] <r00t4rd3d> my dog is mean too, doesnt like anyone, doesnt like to be pet, a little bit of thunder and he morfs into a giant pussy.
[19:23:42] <MattyMatt> I had an xl125r
[19:24:37] <MattyMatt> it was stolen before I could take my test, so I didn't bother with legal learner bikes after that :)
[19:24:57] <MattyMatt> 500cc triumph next
[19:32:41] <r00t4rd3d> i keep mine in a locked garage and chained to a fuel oil tank
[19:48:17] <tjb1> hey r00t
[19:52:09] <r00t4rd3d> yeah
[19:53:12] <r00t4rd3d> whats up

[21:31:15] <r00t4rd3d> Its about time for off topic hour isnt it?
[21:44:30] <tom3p> jthornton, nice tutorial! fyi on bottom of page 6e, the link to next page is said to be 'Next: Part 6e Creating Jog Buttons 6e' ( easy to see its really 6f)
