[02:20:32] <Deejay> moin
[06:01:01] <_methods> CaptHindsight: yeah
[06:01:03] <_methods> lol
[07:10:15] <__rob> whats the best way to hold a small diamter bit of ally in a lathe ?
[07:10:27] <__rob> each time I remove it and put it back in, its not running true
[07:10:30] <Tom_itx> collet
[07:10:37] <__rob> right, thought so
[07:11:18] <archivist> morse taper collets are cheap enough
[07:11:47] <archivist> they only work on exact sizes though
[07:12:01] <__rob> there is a colet adapter for this proxxon lathe
[07:12:05] <__rob> its a micro thing
[07:12:23] <__rob> but, I dont have the collet face adapter
[07:12:32] <__rob> I do have a straight shank er20 holder
[07:12:42] <__rob> that should be ok in a 3 jaw chuck no ?
[07:12:42] <archivist> best to do everything in one setting
[07:13:32] <archivist> ER collets are not the best for random clamping bar has to be full length of collet
[09:25:21] <TekniQue> eeeek
[09:25:39] <TekniQue> wrong window
[09:39:06] <gregcnc> do video related issues still cause latency problems in newer hardware?
[09:42:35] <gregcnc> the HP 8000 SFF is close to running well. the cpu idle setting made a huge difference and it now runs about 5us or less, except for random spikes. Feels like related to starting a video on browser or sometimes just switching programs.
[09:43:44] <archivist> load a large text file in gedit, then grab the scroll bar
[09:51:18] <gregcnc> seems like maybe opening a file spiked it, but not consistently.
[09:53:55] <archivist> varies depending on the phase of the moon
[10:00:30] <CaptHindsight> gregcnc: yes, video like X :)
[10:02:57] <CaptHindsight> more and more things that used to be in only the video driver have made it into the kernel and X
[10:04:02] <gregcnc> OK, On the old P3 900 with 8.04 I think i ended up with the vesa driver for the agp card.
[10:06:35] <gregcnc> this is a older 2.7 pre install updated through updater
[10:07:17] <gregcnc> there was a link where you could download all the different iso, but I can't seem to find it?
[10:22:26] <gregcnc> It's just running some glxgears and shows two spikes of ~30us 15 minutes apart.
[10:23:24] <CaptHindsight> opening a large application for the first time tends to cause spikes
[10:23:25] <archivist> things like network, power management and disk interrupts
[10:23:45] <CaptHindsight> flash in firefox was a real latency killer
[10:24:11] <gregcnc> how can i look at interrupts? there was something in a forum post but it doesn't work in wheezy
[10:24:40] <gregcnc> https://forum.linuxcnc.org/forum/18-computer/25927-reducing-latency-on-multicore-pc-s-success
[10:25:23] <CaptHindsight> debian and ubuntu also have everything including the kitchen sink kernels plus the distro starts all sorts of services that you probably don't use
[10:26:04] <gregcnc> are there barebones linuxcnc isos?
[10:26:24] <CaptHindsight> what works depends on which kernel and what version of RTAI you're using
[10:27:28] <CaptHindsight> also is 30uS ok?
[10:27:36] <gregcnc> yeah i gather that
[10:27:54] <gregcnc> my old machine is like 16.
[10:28:09] <CaptHindsight> what cpu is the new machine?
[10:28:29] <gregcnc> coreduo
[10:29:25] <gregcnc> E8400
[10:29:29] <CaptHindsight> try isolcpus=1
[10:30:44] <gregcnc> running that, what made the biggest difference was
http://wiki.linuxcnc.org/cgi-bin/wiki.pl?RealTime
[10:31:21] <archivist> and servo or stepper
[10:31:53] <gregcnc> this mentions using isolcpus=2,3 if you don't turn off HT. bios doesn't have options for turning of HT so that's my next step.
[10:32:15] <CaptHindsight> for a 4 core or more cpu
[10:32:21] <CaptHindsight> you only have 2 cores
[10:33:06] <gregcnc> step/dir unless i cough up enough for another mesa setup to upgrade this machine.
[10:33:11] <gregcnc> " You do this by adding a kernel boot parameter to GRUB: "isolcpus=1" (or "isolcpus=2,3" if you leave HT on)"
[10:34:00] <gregcnc> I understand it the same as you but the author wrote that
[10:34:00] <CaptHindsight> I wrote most of that wiki page
[10:34:29] <CaptHindsight> HT should be on
[10:34:45] <gregcnc> I can't turn it of
[10:35:25] <CaptHindsight> depending on the version of RTAI what happens will change with that parameter
[10:35:53] <CaptHindsight> try =1, then try the =0 or whatever and see if gets better or worse
[10:36:04] <CaptHindsight> RTAI was a train wreck
[10:36:28] <gregcnc> OK, i was going to turn it off to see what happens
[10:37:03] <CaptHindsight> memleak cleaned it up and added all the 64b support and several other things
[10:37:13] <lair82> Hey guys, what is best way to search the irc logs for a conversation I had a few months back?
[10:38:14] <CaptHindsight> but he stopped since the xenomai devs and Paolo at RTAI took his work and never gave him any credit, so he stopped
[10:38:15] <cradek> I don't know a good way except to futz around with google
[10:38:40] <CaptHindsight> so I expect RTAI to fall back into disarray
[10:42:54] <FloppyDisk5_25> lair82 - not sure the backlog is saved.
http://superuser.com/questions/636414/how-to-see-chat-history-in-irc-channel
[10:43:56] <FloppyDisk5_25> I've copied/pasted a few things out of hexchat, but that's all I've ever done... And, I saw archivest had done that as well.
[10:44:43] <gregcnc> =0 was a mess
[10:46:54] <CaptHindsight> gregcnc: it's common for settings to get flipped, where what used to work becomes just the opposite, so settings like 1's need to be 0's
[10:47:38] <CaptHindsight> then someone else will change some section of the code and it's back to 1's again
[11:10:38] <PetefromTn_> anyone need a milling attachment for a lathe there is on one facebook for 150 in green bay
[11:13:43] <FloppyDisk5_25> lair82:
http://www.tomsguide.com/answers/id-2052675/irc-channel-history-connected.html looks like either ask or see if the custom/history is saved for this.
[11:21:48] <neckro23> yeah if you wanna log IRC you gotta do it yourself
[11:22:03] <FinboySlick> Or ask the NSA.
[11:22:33] <FinboySlick> I'm pretty sure Jymmm said lots of things about bombs and president and stuff the other day, they should have logs.
[11:28:18] <gregcnc> it may be that flash on the browser is what was causing it
[12:00:18] <Roguish> neckro23; there are copies of both IRC channels available.
[12:00:38] <Roguish> the channels are logged on a pretty regular basis.
[12:00:52] <Roguish> several times a day.
[12:02:41] <PetefromTn_> so you mean all that bullshit I have been typing in here does not just disappear into the ether then? ;)
[12:04:09] <pcw_home> anything you say can and will be used against you
[12:04:12] <ssi> the internet never forgets
[12:05:18] <PetefromTn_> BASTARDS!! :D

[12:06:17] <PetefromTn_> ssi WTH is that? hehehehe
[12:06:26] <ssi> it's jazz, man
[12:06:26] <ssi> jazz
[12:06:55] <PetefromTn_> that ain't no kinda jazz I ever heard.....thankfully ;)
[12:07:30] <ssi> https://www.youtube.com/watch?v=kSZlyNGj3dg
[12:08:45] <PetefromTn_> man I gotta learn to play my Takameni here at some point so I can play with my dog....I could be even MORE famous ;)
[12:11:15] <PetefromTn_> ssi so you are flying to Cali for that job? Are you gonna rent your house here or sell it?
[12:11:21] <ssi> I'm not moving to cali
[12:11:35] <PetefromTn_> you know you want to ;)
[12:11:38] <ssi> just going out for three weeks for onboarding
[12:11:40] <ssi> then I'm full time remote
[12:12:11] <_methods> schweet
[12:12:32] <PetefromTn_> sigh I wanna be full time remote :(
[12:12:37] <_methods> me too
[12:12:48] <ssi> me too
[12:12:53] <ssi> that's why I turned down another job for WAY more money
[12:12:56] <_methods> i can do most of my job from the house
[12:13:03] <_methods> but like today i'm stuck welding all day
[12:13:06] <ssi> like 30k more a year, plus a $5k signing bonus and $40k annual bonuses
[12:13:16] <ssi> but I told them no
[12:13:24] <ssi> because I want to be full time remote
[12:13:26] <PetefromTn_> ssi teach me man I will be your pupil and you can show me how the code flys
[12:13:37] <ssi> PetefromTn_: lol you have a big ladder to climb
[12:13:44] <PetefromTn_> I'm fit ;)
[12:13:52] <ssi> ok tell ya what
[12:13:53] <ssi> https://www.coursera.org/learn/build-a-computer/home/welcome
[12:13:54] <ssi> do that class
[12:14:00] <ssi> if you get through it, we'll talk :)
[12:14:08] <ssi> it's actually pretty easy
[12:14:15] <PetefromTn_> K
[12:14:15] <ssi> they give you everything you need in the lectures and the book
[12:14:25] <PetefromTn_> how much is it>?
[12:14:28] <ssi> it's free
[12:14:32] <PetefromTn_> BEAUTIFUL
[12:14:37] <PetefromTn_> :D
[12:14:38] <ssi> for $49 you can get a certificate
[12:14:57] <ssi> if you don't pay, you can't submit the projects, but you don't need to submit them to measure your progress because they have test cases with them
[12:15:00] <maxcnc> hi all
[12:15:14] <_methods> ugh back to tacking
[12:15:20] <ssi> fwiw, that's a seven week class and I did the whole thing in three days
[12:15:45] <PetefromTn_> I'll get to it right after I finish my house, ..... and clean up my CNC's..... and prep them for shipping......and load up all my worldly belongings....and close on my house....and move to Florida....and find a house....and unload all my stuff....
[12:15:53] <ssi> yeah that's the problem
[12:16:10] <ssi> I make the money I do because I'm motivated to learn this stuff
[12:16:16] <PetefromTn_> I would actually like to learn it seriously tho...
[12:16:21] <ssi> I neglect all the other aspects of adult life
[12:16:30] <ssi> but in theory I can pay someone else to deal with that shit :D
[12:16:31] <PetefromTn_> if for no other reason than to be able to help my daughter with it.
[12:16:48] <PetefromTn_> who are you kidding
[12:16:54] <ssi> how's she doing with the codeacademy stuff?
[12:17:12] <PetefromTn_> you neglect all aspects of adult life because you are busy playing with airplanes and stereos and CNC's
[12:17:17] <ssi> exactly
[12:17:21] <ssi> ie the fun shit
[12:17:23] <PetefromTn_> she is actually working thru it
[12:17:39] <PetefromTn_> best part is she does it without my having to ask her about it...
[12:18:10] <PetefromTn_> she may just be a gee...I mean a computer coding expert after all ;)
[12:18:40] <ssi> not an expert
[12:18:43] <ssi> expert implies experience
[12:18:50] <ssi> she may have the aptitude and motivation to learn it
[12:18:52] <PetefromTn_> I mean EVENTUALLY
[12:18:57] <ssi> which is the first step in the path to expertitude
[12:19:01] <ssi> expertise :D
[12:19:02] <ssi> haaha
[12:19:12] <ssi> that's all it takes though, aptitude and motivation
[12:19:16] <ssi> everything else is out on the intertubes
[12:19:24] <ssi> just have to be willing to snatch it up and shove it in your brainmeats
[12:19:28] <PetefromTn_> those amazing intertubes
[12:19:45] <PetefromTn_> I need a USB port for mine
[12:19:50] <ssi> I passed my first written test for my flight instructor rating yesterday
[12:19:57] <ssi> one more written, then the MEI checkride
[12:20:10] <PetefromTn_> COOLNESS
[12:20:14] <ssi> I wanted to get it done before I go to cali, but it's not gonna happen
[12:20:28] <ssi> considering I'll be traveling this time two weeks from now
[12:20:47] <ssi> ohshi did I tell you about the concert?
[12:21:27] <PetefromTn_> you were in a concert?
[12:21:44] <ssi> lol not recently
[12:21:56] <ssi> my friends in san francisco have tickets to see david gilmour at the hollywood bowl
[12:22:06] <ssi> and turns out I'm going to be out there when the concert happens
[12:22:14] <ssi> so I bought a pair of (very expensive) tickets one row behind them
[12:22:15] <PetefromTn_> OH DAMN
[12:22:23] <PetefromTn_> TAKE ME!!
[12:22:26] <ssi> and my mom is flying out to san jose, and gonna ride down in the RV to LA with me for the show
[12:22:44] <PetefromTn_> I would say that will be quite an experience
[12:22:46] <ssi> I'm full of excite
[12:22:51] <PetefromTn_> so full of it
[12:22:57] <PetefromTn_> I mean excitedness
[12:22:58] <ssi> much enthuse
[12:23:00] <ssi> very excite
[12:23:01] <ssi> wow
[12:23:05] <PetefromTn_> hehehe
[12:23:27] <ssi> I'm on a mission to turn my life into even more of an adventure than it's been previously
[12:25:02] <PetefromTn_> you go boy :) I am on a similar adventure
[12:25:08] <ssi> you sure are
[12:25:24] <PetefromTn_> Like I can't wait to take my Kayak offshore and catch a monster and go for a ride :D
[12:26:08] <Jymmm> FinboySlick: But the NSA won't give me me email backups from the 90's !!!
[12:26:21] <Jymmm> FinboySlick: WTH?!?!?!
[12:28:26] <ssi> ooh I should finally go visit mesa while I'm out there this time
[12:29:11] <Jymmm> FinboySlick: I need to get all that ASCII art, it's making a comeback don't ya know ;)
[12:29:37] <PetefromTn_> yeah man tell Pete to get crackin' on those Mesa boards productions... ;)
[12:31:36] <FloppyDisk5_25> Watch out for those sharks chopping kayaks:-)
[12:31:44] <FloppyDisk5_25> umm, chomping.
[12:31:56] <ssi> shark-chopping kayaks?
[12:32:04] <ssi> they have a sharp steel keel that cuts sharks right in half!
[12:32:33] <FloppyDisk5_25> Haven't you heard of sharknado?
[12:32:38] <ssi> of course
[12:33:41] <SpeedEvil> simply replace the prop with one from Blendtek
[12:34:44] <ssi> I have a blendtec
[12:34:48] <ssi> the blades are actually quite dull
[12:34:51] <ssi> it just has absurd power and speed
[12:37:17] <PetefromTn_> I have an armored yak
[12:37:29] <ssi> yak 52?
[12:37:37] <ssi> or yak 55
[12:37:39] <ssi> I think I'd rather hav ethe 55
[12:37:42] <PetefromTn_> it is like a nucleoid submarine :)
[12:37:51] <FloppyDisk5_25> nice...

[13:00:15] <tiwake> hmm
[13:00:58] <tiwake> whats the best way to tell my business partner that I don't want to anodize large runs of stuff?
[13:01:01] <tiwake> lol
[13:01:32] <tiwake> he is basically starting a company that 'is dependent on me anodizing everything'
[13:02:30] <tiwake> guess I could just say no
[13:05:24] <tiwake> did a batch last night and was pushing about 47amps, 600watts though the parts
[13:05:31] <tiwake> couldent breath

[13:10:55] <tiwake> Jymmm: its not just the person anodizing, its everyone in the shop...
[13:11:10] <tiwake> its just a bad idea to anodize where its currently set up
[13:11:13] <Jymmm> tiwake: They are cheap enough =)
[13:11:28] <Jymmm> respirator for eveybody !!! lol
[13:11:32] <tiwake> heh

[13:13:04] <maxcnc> Deejay: ? did you got the homepage in review
[13:15:08] <pink_vampire> good morning internet,
[13:19:47] <maxcnc> im off long workday going home to familie GN8
[13:20:40] <Deejay> good morning sunshine :)
[13:25:07] <enleth> tiwake: do you have space for a tent outside?

[13:25:40] <pink_vampire> 9.55$ for ONE spring!
[13:26:06] <enleth> tiwake: they are quick to set up and take down, so if your anodizing equipment is on a wheeled cart, you could just run it outside...
[13:27:07] <pink_vampire> I can't find any reasonable source for springs.
[13:27:24] <pink_vampire> I need very small springs
[13:28:04] <pink_vampire> 1.5-2.5mm O.D, and 10-12mm length
[13:31:18] <pink_vampire> the first place that I try was fastenal, and they have only bigger springs :(
[13:34:48] <cradek> what's the application?
[13:42:26] <pink_vampire> probe
[13:43:10] <cradek> you're making it yourself?
[13:43:58] <Lowridah> i've found it's easier to just pick up a big spring assortment and find the appropriate one
[13:44:04] <Lowridah> i buy them at crappy harbor freight
[13:44:20] <cradek> ballpoint pen springs are something like 4mm - can you adjust the design to use those?
[13:44:36] <Lowridah> oh 1.5mm is very very small
[13:44:43] <cradek> yeah
[13:45:03] <cradek> to bend that sharply, the wire would have to be very fine
[13:45:36] <roycroft> or annealed
[13:51:22] <gregcnc> check McMaster for springs
[13:51:43] <gregcnc> but don't search metric sizes
[13:51:49] <cradek> (I think I'd try winding my own, but it might not work that small)
[13:52:25] <gregcnc> I've wound springs that small. I forget why
[13:52:50] <gregcnc> using the smallest guitar wire i could get
[13:52:52] <pink_vampire> I need extension spring
[13:53:53] <pink_vampire> very long and fine wire compered to the regular spring
[13:55:10] <gregcnc> http://www.mcmaster.com/#9432k21/=11d8a4i
[13:56:17] <gregcnc> http://www.mcmaster.com/#extension-springs/=11d8als
[13:57:50] <pink_vampire> 10$ for 16..
[13:58:18] <gregcnc> how many thousand do you need?

[14:00:34] <pink_vampire> I'm joke.. but It's just a piece of metal, like bolt, screw, washer.. why it's cost 1000 times more??
[14:01:47] <gregcnc> springs are not so much a commodity item
[14:02:50] <pink_vampire> I need servo spindle :(
[14:03:14] <anomynou1> why
[14:03:23] <anomynou1> tapping?
[14:03:57] <pink_vampire> to make my own sprigs..
[14:04:06] <anomynou1> sprigs?
[14:04:10] <anomynou1> springs?
[14:04:51] <pink_vampire> yes..
[14:05:24] <gregcnc> my spring box has springs like that in it, probably pulled from junk printers
[14:06:37] <pink_vampire> I don t like junk :(
[14:07:14] <gregcnc> me neither when the printer died I stripped it and it was gone.
[14:07:38] <pink_vampire> I have old printer here..
[14:08:09] <pink_vampire> but I want to use parts with UPC..
[14:09:10] <pink_vampire> something that I can order the same thing..
[14:13:32] <gregcnc> mcmaster prices for springs are fair. lee spring wants 6.95 each for 10 if the one above or $0.724 each /1000
[14:14:10] <pink_vampire> I need a servo spindle :)
[14:14:41] <pink_vampire> or 4th axis
[14:14:57] <Akex_> Or both ;)
[14:15:48] <pink_vampire> I don't think that mach3 support 2 spindles
[14:16:38] <enleth> on topic of servo spindles - is it common to have both a servo and a regular 3-phase induction motor coupled together in the spindle drivetrain? not for simultaneous use of course
[14:16:56] <enleth> obviously it needs to be a brushless servo
[14:17:23] <pink_vampire> I have nema 34 DC motor
[14:18:01] <enleth> this doesn't seem to be a bad idea for any reason in particular, but there might be a catch I'm not seeing
[14:18:53] <gregcnc> additional servo on spindle is common in lathes with C axis
[14:19:33] <pink_vampire> but for making springs, I think to use a screw as a guide for the coils
[14:21:18] <pink_vampire> and I need to make M2 tapping in mild steel (fun)
[14:24:20] <pink_vampire> http://i.imgur.com/q3ioYP2.png
[14:25:14] <enleth> gregcnc: is it usually permanently coupled to the drivetrain like the main motor?
[14:25:27] <pink_vampire> bottom I.D 1.2mm top I.D 3mm length, 7 mm
[14:25:53] <enleth> I imagine it would be possible to make a big hollow shaft servo whose rotor *is* the spindle, too
[14:26:49] <pink_vampire> do you mean to the draw bar?
[14:29:42] <pink_vampire> do you mean to the draw bar?^
[14:29:49] <pink_vampire> enleth: ^
[14:30:39] <enleth> pink_vampire: no, I was talking about a direct drive servo spindle for angular positioning of the spindle
[14:30:53] <enleth> just wondering if it's a thing in the industry
[14:31:21] <pink_vampire> almost all the high speed spindles is direct drive.
[14:32:11] <enleth> but those are not servos
[14:32:50] <pink_vampire> you can put an encoder on them for the low speed..
[14:35:07] * Loetmichel2 just bought himself a new car radio because the old one dosent hold the memory even if it has 12V backup battery all the time... i have really plunged into expense this time and am really interested in how well that will work. If at all: http://www.ebay.de/itm/401018590421 ;-)
[14:45:12] <gregcnc> enleth
http://blog.cnccookbook.com/2012/03/18/c-axis-turning-and-live-tooling-turning-and-milling-on-one-machine/
[14:49:32] <gregcnc> I understand it's also normal to use a brake while c axis is active
[14:51:23] <Sync_> enleth: you can position an async spindle just fine
[14:51:39] <Sync_> but yes, there are a lot of servo spindles
[15:01:30] <enleth> I've even found a guy who retrofitted a servo as the main motor in a bridgeport
[15:02:18] <gregcnc> What do you want to do?
[15:02:22] <enleth> although there is one problem with that if used for positioning: the splines have some considerable backlash
[15:03:08] <enleth> right now, just see what makes sense for a possible future upgrade, no immediate plans
[15:07:03] <gregcnc> unless you want to tap really fast what would it be used for in a mill? I'm asking because I don't know
[15:08:55] <pink_vampire> for M2 bottom tapping it's better to do it by hand? or with servo spindle?
[15:10:24] <gregcnc> tapmatic tapping head if it's more than just a couple holes
[15:13:45] <gregcnc> pink which machine do you have again?
[15:26:26] <pink_vampire> G0704
[15:26:48] <pink_vampire> gregcnc: ^
[15:28:26] <pink_vampire> ?
[15:29:23] <gregcnc> I thought I saw some reasonably priced AC servos/drives for driving the spindle for machines of that size, but can't find it now
[15:31:30] <pink_vampire> for 3 springs to make a servo spindle conversion.. it's (a bit) over kill..
[15:32:28] <Cromaglious_> great I just looked up the IRS form 1040 omb number and it's expired right now
[15:33:00] <Cromaglious_> AGENCY: TREAS-IRS OMB CONTROL NUMBER: 1545-0074 EXPIRATION DATE: 02/29/2016 ICR REFERENCE NUMBER: 201404-1545-009
[15:54:38] <pink_vampire> Cromaglious_: what are you talking about?
[15:57:54] <pink_vampire> how I can fine the SFM of material?
[15:58:01] <pink_vampire> find*
[16:03:09] <gregcnc> cutting speed depends a lot on the tool, best to look it up in the tool makers data
[16:14:19] <pink_vampire> https://www.youtube.com/watch?v=pQZbYyEqYo0
[16:14:23] <pink_vampire> OMG^
[16:15:21] <pink_vampire> gregcnc: I'm talking about bismuth
[16:15:44] <pink_vampire> I think it's similar to lead / copper.
[16:18:24] <Deejay> gn8
[16:55:08] <Cromaglious_> wow someone actually using a ip6 address
[17:13:18] <Lowridah> i think HE still does 4to6 conversion for free
[17:21:20] <__rob> anyone done much anodising ?
[17:21:55] <__rob> only really want to coat specific surfaces, or at least not anodise certain mounting faces
[17:22:17] <Sync_> paint them
[17:23:47] <Lowridah> ive home anodized stuff red
[17:23:53] <Lowridah> you can't do it at home and have it be effective
[17:23:58] <Lowridah> a few months in the sun and it's all pink
[17:24:14] <Lowridah> i did a couple parts in black, now they look like they're just oxy'd aluminum
[17:24:43] <__rob> ahh, was that food coloring ?
[17:24:49] <gregcnc> isn't that an issue with the dye used?
[17:24:52] <__rob> I read somewhere that fades but proper stuff shouldn't
[17:25:04] <Sync_> yup, proper dyes should not fade
[17:29:21] <Sync_> zeeshan|2: make my simulation simulate faster!
[17:32:06] <Lowridah> yea i used rit, maybe a specific and specialized dye would work better
[17:32:16] <Lowridah> i'll just take parts in from now on though, it's not worth the effort imo
[17:33:04] <Sync_> I had good results
[17:33:25] <Sync_> and it is not a lot to do, just etch them clean and anodize
[17:33:45] <__rob> what about tool marks in pockets and stuff ?
[17:33:53] <__rob> you polish that out first ?
[17:34:25] <Lowridah> yea i forget most people don't workshop in a little apartment, it's probably no chore when you have the space
[17:36:58] <Sync_> obviously __rob
[18:11:55] <gregcnc> I found an old lucid lynx iso and it runs stable at 22us servo, 12us base from the cd on the HP8000 with no random spikes
[18:59:39] <andypugh> Lowridah: My workshop is a small-size single garage. A bit tightt with a lathe, a mill, a lathe-mill combo, welding stuff, workbench, motorcycle and bicycle.
[19:13:44] <pink_vampire> hi
[19:14:06] <Crom> there you is pink_vampire
[19:14:53] <pink_vampire> hi Crom
[19:15:02] <Crom> that thing earlier was about the tax form 1040. It contains a OMB number and this morning when I ran it, it said it was expired
[19:17:03] <pink_vampire> you need to pay more attention to certain stuff..
[19:18:52] <Crom> I got a print out of the page, than ran it again this afternoon and it had magically changed from 2/29/2016 to 3/31/2016
[19:19:04] <Crom> and I printed that out as well
[19:21:20] <pink_vampire> I have a problem with something that I design. I want to make it ridgid, but it's look bulky :(
[19:21:54] <Crom> material?
[19:22:04] <pink_vampire> steel
[19:22:19] <Crom> gussets?
[19:22:49] <Crom> too long?
[19:23:30] <pink_vampire> I don't have a lathe, so it make it complicated to make.
[19:23:57] <Crom> what state are you in?
[19:24:04] <pink_vampire> NY
[19:24:20] <Crom> how big of piece are we talking?
[19:24:21] <Sync_> pink_vampire: FEM and topology optimization
[19:24:42] <pink_vampire> Sync_: what do you mean?
[19:24:45] <Crom> will it fit in a flat rate large, medium, or small box?
[19:25:28] <Crom> I have a lathe
[19:25:39] <pink_vampire> I'm very limitd with the stuff that I can cat un the G0704.
[19:26:06] <pink_vampire> it's a touch probe.
[19:26:31] <Sync_> pink_vampire: that's how you make it rigid and non bulky at the same time
[19:26:31] <Crom> ahhh one of those...
[19:27:02] <pink_vampire> Sync_: ?
[19:27:43] <Crom> I'm not great at threading, but I can turn a body for you
[19:27:56] <pink_vampire> I have very good design that based on 1/4" X 2" steel bar
[19:28:07] <Sync_> well, if you want rigidity and lightess, you should probably run simulations
[19:28:25] <pink_vampire> but I can't make it close
[19:29:19] <pink_vampire> I know it can work fine without a case.
[19:29:19] <Crom> url?
[19:29:41] <Sync_> well, you can turn parts on your mill just fine
[19:29:51] <Sync_> put a tool into your vise and chuck the part
[19:30:22] <pink_vampire> I need to make internal thred
[19:30:48] <Sync_> so?
[19:31:23] <Crom> hmm so I need to pick up a threading boring bar
[19:31:33] <Sync_> grind a tool and mill the thread
[19:33:12] <archivist> make a thread mill
http://www.collection.archivist.info/searchv13.php?searchstr=thread+mill
[19:34:27] <Tom_itx> archivist what size threads is that made to cut?
[19:34:50] <archivist> whatever insert one puts on it
[19:35:11] <Crom> thread milling is pretty easy on a cnc machine
[19:35:17] <Tom_itx> well let me reprase that... what size bar is that?
[19:35:40] <archivist> about 25-30mm dia
[19:37:53] <Tom_itx> for OD ID or both?
[19:38:11] <pink_vampire> one sec
[19:38:15] <pink_vampire> phone,
[19:38:25] <archivist> it was for external threads
[19:43:03] <pink_vampire> I'm back
[19:44:06] <pink_vampire> I'm trying to a avoid complicated parts.
[19:45:27] <Tom_itx> why?
[19:45:49] <pink_vampire> mop
[19:46:56] <pink_vampire> more complex parts, mean more machining time for no reason
[19:47:30] <Sync_> then design your part simpler
[19:47:40] <Sync_> or just make the tool and mill your thread
[19:47:44] <Sync_> or buy a thread mill
[19:48:55] <pink_vampire> but the main problem to make it this way, is the cover.
[19:49:31] <Crom> with a boring head, boring bar, and run the head backwards
[19:50:11] <pink_vampire> I don't have a borinr
[19:50:25] <pink_vampire> boring bar*
[19:50:58] <pink_vampire> just regular and mills and fly cutters.
[19:51:08] <Sync_> buy or make one
[19:52:22] <pink_vampire> but anyway I want to make it from the steel bar that I have..
[19:54:14] <pink_vampire> I need to get better material..
[19:54:54] <pink_vampire> 1" rod..
[19:56:11] <pink_vampire> maybe brass insted of steel
[19:57:10] <pink_vampire> something that will be easier to machine
[19:58:21] <Sync_> steel should not be a problem
[19:58:59] <pink_vampire> I have hot rolled steel from home depot
[19:59:24] <_methods> you mean rebar lol
[20:00:22] <_methods> they rip people off so bad on the metal they sell
[20:00:56] <_methods> every time i walk by that metal rack i laugh for about 5 minutes
[20:01:31] <gregcnc> sure, but markup has to be inline with all the other junk they sell
[20:02:20] <pink_vampire> I'm trying to find the link for it
[20:05:47] <pink_vampire> http://www.homedepot.com/p/Everbilt-2-in-x-3-8-in-x-36-in-Plain-Flat-Bar-800237/204331419
[20:05:50] <pink_vampire> this one
[20:06:40] <pink_vampire> _methods: , gregcnc ^
[20:06:53] <_methods> hahah
[20:06:59] <_methods> you can get a 20' stick for that price
[20:08:17] <pink_vampire> where you get your materials?
[20:08:49] <pink_vampire> and al
[20:08:58] <gregcnc> I picked up some cast iron direct from durabar, the price was great even at minimum order
[20:09:40] <pink_vampire> and also it get hardend if I machine it slow.
[20:09:56] <pink_vampire> durabar is a place?
[20:10:03] <gregcnc> for small pieces, places like speedmetals.com onlinemetals.com even mcmaster
[20:10:06] <gregcnc> foundry
[20:10:24] <gregcnc> speefymetals.com
[20:10:28] <gregcnc> carp
[20:10:39] <gregcnc> speedymetals.com <
[20:10:39] <_methods> i need to get some durabar i need to make some straight edges and angled straight edges
[20:10:43] <pink_vampire> the shipping is very expensive,
[20:11:20] <gregcnc> yes, check for a local place. we have metalsupermarkets around here
[20:11:35] <pink_vampire> where is here?
[20:11:45] <gregcnc> chicagoland
[20:11:55] <pink_vampire> ;(
[20:12:36] <gregcnc> http://metalsupermarkets.com/store-finder/ there's one in NYC
[20:13:30] <pink_vampire> Fairfield, New Jersey, 07004
[20:13:58] <gregcnc> just across the bridge?
[20:14:50] <pink_vampire> lt's see
[20:15:35] <gregcnc> there are plenty of metal distributors around, but few will cut just a few inches for you at a rate that's not stupid
[20:15:54] <gregcnc> there's always ebay
[20:17:42] <pink_vampire> I don't care to get large bars
[20:17:56] <pink_vampire> I have a bandsaw
[20:21:45] <pink_vampire> what is the cheapes and easiest steel to work with?
[20:22:22] <_methods> cold rolled
[20:23:01] <PetefromTn_> hot rolled is generally cheaper
[20:23:53] <_methods> cold rolled is easier to work with
[20:23:58] <PetefromTn_> yeah
[20:23:59] <_methods> 12L14
[20:24:04] <_methods> is easiest to machine
[20:24:40] <andypugh> EN1A
[20:25:13] <pink_vampire> what is EN1A?
[20:25:24] <andypugh> I buy a lot of metal from eBay. Plenty of folk there buy 3m lengths and sell short bits.
[20:26:12] <PetefromTn_> I get some good deals on ebay as well if I can't get it locally quicker
[20:26:12] <andypugh> It’s a UK spec. Actually one that went out of use in abotu 1970 (all the EN numbers did) but are still common-parlance.
[20:26:31] <pink_vampire> so.. I want to get long bar cheap and cut it as I need..
[20:26:41] <andypugh> http://www.ebay.co.uk/sch/i.html?_from=R40&_trksid=p2050601.m570.l1313.TR6.TRC2.A0.H0.XEN1A.TRS0&_nkw=EN1A&_sacat=0
[20:27:09] <andypugh> If you want a fill bar (3m) then any metals stockist will be happy to sell you one.
[20:29:02] <andypugh> The EN numbers came in during the war, a rationalised set of steels with only as much alloying elements as needed. Nowadays youhave EN1A as mild steel for things that don’t matter. EN8 for more hightly-stressed things and EN24 for when you need something properlt strong.
[20:29:16] <pink_vampire> how much is reasonable price for 2" by 2" 3m
[20:29:45] <andypugh> square?
[20:29:51] <pink_vampire> yes
[20:30:27] <andypugh> https://www.metals4u.co.uk/mild-steel/square/bright-square/50mm/p3174
[20:30:32] <andypugh> That’s about $300
[20:30:34] <PetefromTn_> easiest way to find out is to check with onlinemetals and metals depot for these you can generally get it locally for a bit less
[20:32:04] <pink_vampire> just to get an approximation
[20:32:58] <pink_vampire> BRB
[20:33:00] <andypugh> Bear in mind that that is 60kg (272lbs) of metal.
[20:33:54] <pink_vampire> have to go for
[21:19:02] <Erant> Are there any USB UART dongles that are an especially good or bad idea with LinuxCNC?
[21:19:10] <Erant> Chipsets, more accurately.
[21:24:31] <CaptHindsight> Erant: USB for what?
[21:25:12] <CaptHindsight> real time doesn't work over USB unless you put the real time on the USB device side vs PC side
[21:26:28] <Erant> Oh, I know.
[21:26:35] <Erant> This is for a little LCD status display
[21:26:43] <Erant> Nothing critical.
[21:27:25] <Erant> (Also, USB is a bad idea for anything real time no matter where you put the RT component)
[21:30:12] <CaptHindsight> then it's just down to if the drivers for your device are in the kernel
[21:30:59] <Erant> Yeah, I was hoping to just find a damned CDC device, but those are rare-ish.
[21:33:07] <FloppyDisk5_25> Erant - This USB-serial was recommended years ago by Parker Compumotor for the gemini brands
[21:33:08] <FloppyDisk5_25> http://www.amazon.com/gp/product/B00009L598
[21:33:35] <FloppyDisk5_25> There were issues because the gemini's rec'd HEX instead of ASCII and these seemed to work better. I have 2 of them.
[21:33:41] <FloppyDisk5_25> No idea on linux, though. Sorry.
[21:37:23] <Erant> I have a pile of them here that I mostly use on Mac OS X, I'll just see if I can find one of the ones I didn't convert to TTL.
[22:07:11] <pink_vampire> hii all I'm back.
[22:09:36] <pink_vampire> Tom_itx: ? gregcnc? PetefromTn_? _methods?
[22:11:15] <gregcnc> Capthindsight looks like onboard graphics runs better than the old ati card in this HP8000. full screen youtube still spikes it but only 15-20us
[22:11:31] <pink_vampire> http://www.ebay.com/itm/New-99-99-Magnesium-Metal-Rod-Mg-18mm-x-100mm-High-Purity-1PC-/281579481602?hash=item418f71ea02:g:~kkAAOSwyQtVpLMv
[22:11:43] <pink_vampire> what do you think about that?
[22:12:03] <gregcnc> fire starter?
[22:12:42] <pink_vampire> noo
[22:12:53] <pink_vampire> to machine it..
[22:13:23] <pink_vampire> than the chips...
[22:13:32] <gregcnc> start a fire
[22:13:58] <gregcnc> why magnesium?
[22:14:27] <pink_vampire> I don't know I just saw it..
[22:14:39] <pink_vampire> and it's look cool..
[22:15:01] <gregcnc> it will oxidize
[22:16:59] <pink_vampire> you can put it in mineral oil
[22:17:34] <gregcnc> not me
[22:18:24] <gregcnc> for appearance you want something that doesn't need attention
[22:20:29] <pink_vampire> i think the coolest thing to do from magnesium is self dissolve implants
[22:20:37] <yasnak> anyone ever built any cnc "material handling" type robot setups? one maybe with vision?
[22:21:33] <pink_vampire> yasnak: what do you mean?
[22:21:56] <yasnak> well, i have a laser marker that must be ran by someone basically pick and placing parts into a fixture and the laser running
[22:21:58] <yasnak> over and over
[22:22:04] <yasnak> seems like a waste, wanted to automate it
[22:22:15] <yasnak> without the 100k industrial pricetag
[22:32:34] <MrHindsight> yasnak: opencv
[22:32:41] <yasnak> yeah?
[22:32:57] <MrHindsight> http://opencv.org/
[22:32:58] <yasnak> i'll look into it...i want to build this or find a solution
[22:33:25] <MrHindsight> https://www.youtube.com/watch?v=Pe2RACwiEbg Circle recognision - opencv to linuxcnc
[22:34:45] <MrHindsight> one of my goal is to use opencv along with some pick-n-place on Linuxcnc
[22:34:53] <yasnak> yeah
[22:34:56] <MrHindsight> no *dunio version
[22:35:17] <yasnak> I want to build something exactly like that on the cheap as a quick fix, then go ahead and get the big rig when demand comes
[22:35:51] <MrHindsight> http://delta.firepick.org/
[22:36:29] <MrHindsight> I understand that the goal was low cost pick-n-place but this is just way too ghetto
[22:36:59] <yasnak> has anyone ever built one?
[22:37:10] <MrHindsight> http://delta.firepick.org/documentation/
[22:37:19] <yasnak> i mean it looks well documented...but i know how engineers can somewhat lose it when it comes to actually working haha
[22:37:33] <MrHindsight> the main dev was off in China building some other crappy version pick-n-place
[22:42:35] <PetefromTn_> Huh I ordered some replacement screws for my Maritool Facemill when I bought it and broke two of them now testing in steel and could not for the life of me find the replacement screws anywhere...
[22:43:04] <PetefromTn_> I took out my big box of receipts to work on my taxes and found them in a small baggie in the bottom of the box ;)
[22:44:27] <yasnak> mrhindsight, you build one i'll buy it haha
[22:44:47] <yasnak> im kidding, i'll look into this. need to find time, onto the weekends!@
[23:56:04] <[cube]> quick little cnc project for you guys to tackle this weekend:
