[01:52:02] <Loetmichel> mornin'
[01:57:00] <Loetmichel> ... *boom* there is a hole in the autobahn... they couldnt defuse the 500kg british dud bomb... they had to detonate it in place... result:
http://primavera24.de/top-meldung/schwarz/bombenfund-bei-bauarbeiten-a3-voll-gesperrt/84928 ... aoutobahn A3 will be closes for the next days for repairs :-( (thats on my commute to work...)
[01:59:20] <archivist> too lazy to grind there way in with water jet
[01:59:41] <Loetmichel> archivist: chemical fuse
[01:59:45] <Loetmichel> very unstable
[01:59:59] <Loetmichel> and rusted down beyond recognition
[02:00:53] <archivist> if they were using a remote device to bore a hole to remove the content I dont see a problem
[02:01:56] <Loetmichel> i think the defusers know their job. if they say its to risky to defuse it it is made so ;-)
[02:03:08] <archivist> is there even a water jet cutter for defusing in existence
[02:04:08] <Deejay> moin
[02:05:20] <archivist> Loetmichel, seems the answer is yes
[02:40:37] <IchGuckLive> hi all
[02:40:44] <alex_joni> hi
[02:41:38] <IchGuckLive> somone shoudt have given benjamin the video in my channel about xbox controler OR better the wikipedia linuxcnc report
[02:42:00] <IchGuckLive> Loetmichel: did you got hit by stoines from the blast
[02:43:30] <IchGuckLive> chd: guten morgen
[02:43:37] <IchGuckLive> all clear in mayeen
[02:44:09] <chd> ah, moin. Yes, clear sky :-)
[02:44:33] <IchGuckLive> its cold up there i jheard about freesing temps
[02:44:48] <chd> Mayen near Nürburgring ;-)
[02:45:11] <chd> yes, here we are at 10°C now, started from 6°C
[02:45:14] <IchGuckLive> the high 8 is a cold place to live
[02:46:05] <chd> Yes, around 750m high, but here we are at 300
[02:47:47] <chd> Yesterday I modified the glcanon.py. I found the place where to change the number of decimals - but I got no result in an simulated gmoccapy
[02:48:37] <chd> As I know I don't have to recompile it becuase the python interpreter looks for changed source files by itself, or am I wrong?
[02:49:07] <IchGuckLive> if Benjamin23 joins back pleas direct him towards
http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Using_A_Joypad_To_Move_Your_CNC_Machine
[02:49:50] <chd> Here someone asked before:
http://www.linuxcnc.org/index.php/german/forum/21-axis/27271-show-only-2-decimal-cases-on-dro
[02:50:06] <chd> but I still got three decimals :-(
[02:50:35] <IchGuckLive> gmoccapy uses a other gui interface
[02:52:17] <IchGuckLive> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Simple_Remote_Pendant PLEASE to benjamin if he joins back Thanks
[02:52:31] <IchGuckLive> im off till LATER
[02:52:42] <chd> ok, bye :-)
[03:17:40] <Loetmichel> ich: no, but i heard the bang at home
[03:51:59] <Loetmichel> *gnah* and again 230 eur down the drain... killed abnother shielding glass pane at rubbing in the copper frame :-(
http://www.cyrom.org/palbum/main.php?g2_itemId=14919
[05:03:28] <chd> What is the shielding glass exactly for?
[05:18:52] <archivist_herron> stops oxidization and inclusions
[05:19:11] <archivist_herron> if welding
[05:19:39] <archivist_herron> if cutting do you mean the oxygen, that burns the metal
[05:29:41] <chd> ah ok
[05:38:42] <Valen> chd the glass is conductive, Loetmichel uses them to make special monitors and the like so the NSA can't spy on his government
[06:15:55] <Loetmichel> more precise: the glass has an 0.1mm copper mesh embeddend
[06:16:58] <Loetmichel> chd:
http://www.cyrom.org/palbum/main.php?g2_itemId=12454&g2_imageViewsIndex=1
[06:17:00] <Loetmichel> you see?
[06:17:15] <chd> yes, tnx :-)
[06:19:27] <chd> interesting photos in your gallery :-)
[06:21:16] <Loetmichel> which in special?
[06:21:54] <chd> I'm interested in the cases - do you mill them or via laser/plasma?
[06:22:18] <Loetmichel> mill
[06:22:44] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=14877&g2_imageViewsIndex=1
[06:23:09] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=14160&g2_imageViewsIndex=1 <- there you can see all states
[06:23:38] <Loetmichel> just milling them with slots at the bends and then bending by hand/small vice
[06:24:42] <Loetmichel> most work is to think ricvht for material that vanishes in the bends
[06:24:50] <Loetmichel> so the screw holes iwll fit ;-)
[06:24:54] <Loetmichel> right
[06:25:11] <chd> good work :-) I'am trying to cut my cases with a fine plasma cutter (stainless steel 0,8 and 1mm)
[06:25:20] <chd> Yes, bending is a real science :-)
[06:25:41] <Loetmichel> most case prototypes i do 3 to 4 times;-)
[06:25:48] <Loetmichel> until i worked out all kinks
[06:26:01] <chd> ;-)
[06:27:13] <chd> For this reason I am modifying my bending machine for automatic backstops - to get fitting sheets
[06:28:25] <Loetmichel> as i bend by had: no bending machine ;-)
[06:28:31] <Loetmichel> i have to tink beforehand
[06:28:36] <Loetmichel> think
[06:28:42] <Loetmichel> hand
[06:29:29] <Loetmichel> its 1.5mm Aluminium, AlMg3, milled down to 0,8mm at the bends
[06:29:36] <chd> Really good work. I will glue my cases - that's much easier and you get flat surfaces.
[06:29:40] <Loetmichel> you can bend it by hand if large enough
[06:29:48] <chd> Yes
[06:29:56] <Loetmichel> for smaller stripes you'll need a vice to get it straight
[06:30:24] <Loetmichel> i cant glue. the cases should be RF tight
[06:30:30] <Loetmichel> ABSOLITELY
[06:30:33] <Loetmichel> up to 4ghz
[06:31:02] <chd> ah ok :-)
[06:31:36] <chd> and using copper foil in side is not an option?
[06:31:57] <Loetmichel> would be. but we are producing for the military mostly
[06:32:04] <chd> uhhh ;-)
[06:32:06] <Loetmichel> soldiers and delicate parts dont mix well
[06:32:21] <Loetmichel> do it "idiot proof" and still some soldier will break things off ;-)
[06:33:35] <chd> What software do you use for CAM? I'm still searching for a good one
[06:33:53] <Loetmichel> dont laugh: corelDraw 8 and BoCNC
[06:34:30] <Loetmichel> i just bought cambam, but have to get used to it
[06:35:35] <chd> @corel: if it works - why not?
[06:35:53] <Loetmichel> more or less
[06:36:01] <Loetmichel> its so old that it doesnt run inder win7
[06:36:09] <Loetmichel> i had to set up a VM with xp ;-)
[06:36:37] <Loetmichel> and of course its 2d only
[06:40:46] <chd> for plasma cutting this is ok - I'm also testing Cambam (it runs native under Linux) - looks fine - but I haven't done a real case with it. First the plasma cutter has to run :-)
[06:43:22] <chd> there are also some programs and plugins for dxf->g-code. Inkscape has a good one
[06:46:19] <chd> ok, I will have to work in my laboratory now - sse you later :-)
[06:46:40] <chd> afk
[08:11:36] <zbychuk> Hi, I have d2700mud motherboard with integrated graphics in cpu
[08:12:04] <zbychuk> i disabled all power saving functions in BIOS
[08:12:23] <zbychuk> disabled Hyperthreding
[08:12:40] <zbychuk> added isolcpus=1 to kernel cmdline
[08:13:45] <zbychuk> and when i run 1 instance of glxgears and iceweasel, and then start moving windows on the screen
[08:14:25] <zbychuk> then jitter latecy 25us jumps to about 18000ns
[08:14:35] <SpeedEvil> In principle, integrated graphics will contend with various resources often.
[08:14:43] <SpeedEvil> At least, for example, for RAM bandwidth.
[08:15:05] <SpeedEvil> Non shared memory cards won't in general be nearly as bad.
[08:15:18] <SpeedEvil> also - 25us to 18000ns is an improvement
[08:16:20] <zbychuk> i tried normal video card on another computer with p3 933MHz but it was worse than integrated video
[08:16:38] <zbychuk> it was S3Virge graphics pci card
[08:16:54] <IchGuckLive> hi all B)
[08:17:06] <IchGuckLive> zbychuk: its ok on steppers
[08:17:53] <IchGuckLive> you easy can reatch 20000 steps per second on that timing
[08:18:19] <zbychuk> when i started linuxcnc livecd on d2700mud first time i had 51000ns jitter latecy
[08:18:41] <zbychuk> but it was without any boot parameters or anything like that
[08:18:42] <IchGuckLive> even that will give you more then 15000 per second
[08:18:55] <IchGuckLive> what are you building
[08:19:31] <zbychuk> i am trying to build something like "mantis cnc 9.1"
[08:19:42] <zbychuk> my new hobby :)
[08:19:47] <zbychuk> i think
[08:20:13] <IchGuckLive> so lowest available issues
[08:20:17] <zbychuk> maybe later i will build something more solid
[08:20:27] <IchGuckLive> at minimum price
[08:20:42] <zbychuk> yah, ok thanks
[08:20:47] <IchGuckLive> ehee are you in the world
[08:20:54] <IchGuckLive> where
[08:20:58] <zbychuk> Poland, Europe
[08:21:03] <IchGuckLive> NICE
[08:21:24] <IchGuckLive> you shoudt start at TR16x4 Trapez tread
[08:21:29] <IchGuckLive> cheep stuff
[08:21:41] <zbychuk> I want to widen my skils set
[08:21:44] <zbychuk> ok
[08:21:49] <IchGuckLive> and steüppers low price kit from china TB6560
[08:22:15] <IchGuckLive> there you can go below 200Euros in first place
[08:23:01] <IchGuckLive> but keep in mind there are good semi pros out for 399
[08:23:10] <IchGuckLive> out of the box
[08:23:41] <IchGuckLive> its hard work on self building
[08:24:14] <zbychuk> ok, thanks
[08:47:03] <CaptHindsight> how far back do you have to go to find PC's that had poor latency with integrated graphics?
[08:49:20] <Fuchikoma> Depends on what you consider to be "poor latency" ;)
[08:49:56] <skunkworks_> my guess would be pentium 3/4 tranistion..
[08:50:16] <CaptHindsight> Fuchikoma: I'm referring to the issue that SpeedEvil mentioned ~1/2 hour ago
[08:50:59] <SpeedEvil> That's why I was saying 'in principle'
[08:51:12] <SpeedEvil> I'm really unsure - but it's going to be worse with integrated low-power stuff
[08:51:24] <SpeedEvil> especially as you get to older hw
[08:53:26] <Fuchikoma> CaptHindsight: 18000ns doesn't seem like high latency to me?
[08:54:16] <Fuchikoma> Unless maybe that's a typo for "ms" which would be absolutely terrible
[08:54:45] <CaptHindsight> that's what I'm not sure of, maybe zbychuk can clarify
[08:55:23] <SpeedEvil> well, 25us to 18000us makes more sense
[08:55:48] <SpeedEvil> And 18ms is basically useless
[08:55:51] <Fuchikoma> It would, especially since 18000ns is actually LESS than 25us.
[08:58:01] <pcw_home> and 25 usec is good on an Atom (which may have hardware latencies in the 50 usec region)
[08:58:17] <CaptHindsight> I've only read about older integrated graphics mainboards having poor latency. I wonder if it was the drivers?
[08:59:18] <pcw_home> also older MBs had much lower memory --> video bandwidth
[09:01:13] <CaptHindsight> pcw_home: looks like 3.14 RTAI is working
[09:01:47] <pcw_home> Thats great
[09:03:26] <pcw_home> does it change any of the video issues/worarounds with newer AMD MBs?
[09:03:35] <pcw_home> workarounds
[09:08:47] <CaptHindsight> pcw_home: have yet to find out later today. He has an APU and a R9 290 board. No driver yet for the R9, but I don't think many will use one for the Linuxcnc setup.
[09:13:19] <CaptHindsight> what version kernel is Wheezy up to?
[09:23:46] <CaptHindsight> pcw_home: the wheezy hybrid iso defaults to using the llvmpipe driver and doesn't need the radeon.modeset=0 kernel parameter
[09:25:48] <CaptHindsight> it has no problem running multiple glxgear windows while playing back HD video and running Linuxcnc
[09:26:29] <CaptHindsight> isolcpus=2.3 parameter is used for the 4 core apu's
[09:33:40] <pcw_home> I thought I would try this MB
[09:33:42] <pcw_home> http://www.newegg.com/Product/Product.aspx?Item=N82E16813138412
[09:37:31] <PetefromTn_> mornin folks
[09:38:14] <dr0w> Seems like I read about some latency issues with linuxcnc and AMD's APUs
[09:38:41] <CaptHindsight> dr0w: you just need the right settings
[09:39:32] <dr0w> Ah.. that's good to know.. those little itx boards have an attractive price point.
[09:40:32] <CaptHindsight> pcw_home: I've had BIOS/EFI problems with Biostar, Not that exact board but their boards in general.
[09:41:37] <CaptHindsight> the new embedded APU boards should out shortly, the older E350 and E450 mini-itx are getting closed out
[09:45:04] <pcw_home> Yeah I would not normally choose Biostar but their the only one with a A4-5000 ATM
[09:45:37] <CaptHindsight> newegg has a good return policy
[09:46:26] <pcw_home> they're
[09:48:21] <pcw_home> Not sure the BIOS issues can be as bad as the Gigabyte J1800, and that was beaten into submission
[10:51:50] <zeeshan> the spindle at speed thing
[10:52:00] <zeeshan> can someone explain what g-codes it effects?
[10:59:30] <CaptHindsight> http://www.chenho.com/ did Taiwan and Madagascar swap islands? :p
[10:59:59] <zeeshan> LOL
[11:44:26] <IchGuckLive> hi all B)
[11:44:57] <jthornton> zeeshan, any G code that uses spindle sync motion
[11:45:18] <jthornton> I think
[11:45:21] <zeeshan> jthornton: i'm trying to ensure my spindle is at speed before executing g01..
[11:45:23] <zeeshan> or g02
[11:45:28] <zeeshan> any linear/radial moves
[11:45:34] <zeeshan> i was really hoping it'd effect those
[11:45:53] <jdh> try it!
[11:46:44] <IchGuckLive> zeeshan:
http://linuxcnc.org/docs/html/man/man9/motion.9.html
[11:47:54] <jthornton> zeeshan, how long does it take to get your spindle up to speed
[11:48:06] <zeeshan> depends on rpm, but if im going from 400 rpm to 1200 rpm
[11:48:13] <zeeshan> about 2 seconds
[11:48:19] <zeeshan> i have a slow ramp on the vfd
[11:48:57] <zeeshan> motion.spindle-at-speed IN BIT Motion will pause until this pin is TRUE, under the following conditions: before the first feed move after each spindle start or speed change; before the start of every chain of spindle-synchronized moves; and if in CSS mode, at every rapid->feed transition.
[11:49:09] <zeeshan> so i guess any linear/arc move is covered
[11:49:13] <zeeshan> cause they are 'feed moves'
[11:49:27] <zeeshan> ok time to try
[11:50:30] <jdh> for your lathe?
[11:52:43] <zeeshan> yes
[12:05:17] <CaptHindsight> 3.14 RTAI works!
[12:07:25] <Jymmm> CaptHindsight: utilizing all the cores?
[12:34:14] <IchGuckLive> zeeshan: is there a need to change rpm at the move
[12:34:25] <IchGuckLive> why not changing at bevor or after
[13:03:21] <IchGuckLive> quiet here ;-)
[13:04:21] <Tom_itx> make some noise!
[13:07:45] <Jymmm> Ahooooooooooooooooooooooooooooga!
[13:15:12] <zeeshan> okay..
[13:15:14] <zeeshan> it seems to work
[13:15:31] <zeeshan> if it goes from 800 rpm to 1000 rpm, itll wait till it hits 1000 before going g01
[13:15:47] <zeeshan> but the thing is if it goes from 1000 rpm to 800 rpm, itll keep going
[13:16:00] <zeeshan> weird.
[13:16:37] <cradek> where are you getting your at-speed signal?
[13:16:38] <skunkworks_> what are you using to sense the spindle speed?
[13:16:45] <skunkworks_> heh
[13:16:46] <zeeshan> haha
[13:16:57] <zeeshan> at speed signal is from the encoder
[13:17:07] <skunkworks_> what hal bits?
[13:17:11] <cradek> encoders don't have at-speed
[13:18:09] <zeeshan> im using the near component
[13:18:19] <zeeshan> and comparing the signals spindle-cmd and spindle-velocity
[13:18:53] <zeeshan> spindle velocity comes from encoder.x.velocity
[13:19:07] <cradek> ok near
[13:19:12] <cradek> what are your near settings?
[13:19:29] <zeeshan> since my spindle-velocity is a small number that comes from the encoder
[13:19:38] <zeeshan> 70:1 ratio..
[13:19:45] <cradek> ??
[13:19:47] <zeeshan> so i do 70*1.05 (within 5%)
[13:19:56] <zeeshan> near.x.scale 73.5
[13:20:14] <zeeshan> that's really the only criteria
[13:20:38] <cradek> I don't understand why your spindle-velocity is off by a factor of 70
[13:20:57] <zeeshan> basically when spindle-cmd is 100rpm , spindle-velocity will output 1.428
[13:21:11] <zeeshan> which is off by a factor of 70
[13:21:13] <zeeshan> i'm not sure lol
[13:21:14] <cradek> usually a spindle should be scaled so one revolution is 1.0 in position, and then the velocity is in rps
[13:21:24] <zeeshan> my encoder.x.position-scale is set to 70
[13:22:02] <cradek> at 100rpm velocity should be 1.667 (100/60)
[13:22:30] <zeeshan> hmm
[13:22:54] <skunkworks_> what is the encoder?
[13:23:05] <zeeshan> 1 index pulse
[13:23:06] <zeeshan> 1 phase z
[13:24:32] <zeeshan> http://linuxcnc.org/docs/html/examples/spindle.html#_spindle_synchronized_motion_a_id_sec_spindle_synchronized_motion_a
[13:24:43] <zeeshan> i literally copied that to setup the encoder and sync motion
[13:24:52] <zeeshan> the only thing diffeerent is mine says 70 not 100
[13:24:57] <zeeshan> and the pins are different
[13:25:20] <zeeshan> and then i copied the spindle at speed section, and changed the near.0.scale to 70*1.05 = 73.5
[13:26:14] <cradek> 70 is not a multiple of 4 so it's really unlikely to be a correct scale
[13:26:34] <cradek> er oops, you only have one sensor, so it could be right
[13:26:38] <IchGuckLive> im off BYE
[13:26:44] <cradek> how many lines/whatevers are on your encoder/whatever?
[13:26:50] <skunkworks_> wouldn't the scale be set to 1?
[13:26:52] <zeeshan> its got 70 slots
[13:26:56] <skunkworks_> oh
[13:26:59] <zeeshan> skunkworks: no, then it doesnt work
[13:27:08] <cradek> doesn't it count on both edges?
[13:27:08] <zeeshan> because its trying to compare 100 and 1.48
[13:27:34] <zeeshan> i dont thinkso, from what i remember when configuring/testing syncro motion
[13:27:51] <zeeshan> it only triggers when it goes from low to high
[13:27:54] <zeeshan> not high to low
[13:27:57] <skunkworks_> zeeshan, explain the encoder again.. How many channels? abz? az?
[13:27:59] <cradek> you're right
[13:28:16] <cradek> then seems like 70 is the right scale
[13:28:27] <zeeshan> skunkworks: one optical encoder that measures an index slot, and one optical encoder that measures 70 slots
[13:28:36] <skunkworks_> ok
[13:28:37] <cradek> you're confusing rpm/rps (60) and 70 (your scale)
[13:28:53] <cradek> I think
[13:28:57] <zeeshan> so spindle-velocity is output as RPS
[13:29:00] <zeeshan> i gotcha.
[13:29:02] <zeeshan> that would make sense!
[13:29:17] <cradek> if 1.0 in position is one rotation, then definitely the velocity output is rps
[13:29:44] <cradek> that's just how encoder scaling works, and is nothing special about rpm/rps/spindle
[13:31:35] <zeeshan> https://www.youtube.com/watch?v=bC13xRoQaqc
[13:31:37] <zeeshan> here is the action :D
[13:31:54] <zeeshan> poor aluminum getting eaten
[13:32:10] <zeeshan> i really need a tripod
[13:34:32] <cradek> yikes, cover up that ballscrew
[13:34:33] <Jymmm> why is the sindle changing speeds on jogging?
[13:34:45] <cradek> that's CSS, a feature
[13:34:53] <Jymmm> ?
[13:34:58] <Jymmm> css?
[13:35:05] <zeeshan> constant surface speed
[13:35:07] <Connor> Constant Surface Speed
[13:35:29] <Jymmm> Ok, but it's not during a cutting motion, it's when jogging
[13:35:39] <zeeshan> Jymmm: its my g-code
[13:35:46] <zeeshan> i need to enable RPM mode before each G00
[13:35:46] <Connor> Does it both
[13:35:59] <Jymmm> zeeshan: ah ok
[13:36:32] <Connor> on the last pass it steps down each time..
[13:36:50] <zeeshan> Connor: yes
[13:36:58] <zeeshan> but it doesnt seem to wait to get to the correct speed
[13:37:04] <zeeshan> before executing a move
[13:37:04] <Jymmm> Is CSS to maintain the finish?
[13:37:25] <zeeshan> Jymmm: finish / extend tool life
[13:37:34] <Jymmm> k
[13:37:52] <Connor> Too bad your ball screw couldn't be under...
[13:38:00] <zeeshan> its okay that it sticks out
[13:38:08] <Connor> and why do you still have the compound cross slide on it?
[13:38:09] <zeeshan> i just need to put a boot on it
[13:38:15] <zeeshan> connor lazy hahaha
[13:38:46] <zeeshan> thats one of the projects to make a solid tool post
[13:38:46] <Jymmm> zeeshan: pool hose?
[13:38:55] <zeeshan> Jymmm: i was thinking tie rod boots from a car
[13:39:10] <zeeshan> http://garage.projectraine.com/content_guides/240_tierodboots/tierodboots03.gif
[13:39:12] <zeeshan> something like that
[13:39:25] <Connor> zeeshan: Make yourself a multigang tool post holder..
[13:39:55] <zeeshan> connor honestly changing the tools isnt too much work for me
[13:40:09] <zeeshan> the main thing i want to get is a quick change morse taper adapter
[13:40:14] <zeeshan> so i can drill using the qctp
[13:40:22] <Jymmm> zeeshan: I was thinking vacuum cleaner hose
http://www.vacuumspot.com.au/media/catalog/product/cache/1/image/9df78eab33525d08d6e5fb8d27136e95/h/s/hs.jpg
[13:40:34] <zeeshan> hmm that might work!
[13:40:36] <Jymmm> then you have spares too
[13:40:47] <Jymmm> cable tie it on
[13:43:34] <Connor> Vacuum cleaner hose might not work.. depends on the kind you get.. most won't compress...
[13:43:59] <zeeshan> just did some measurements of the two test runs, .95 => .9493, .9506, .85 => .8491, .8487, .75 => .7492, .7493, .5 => .,4970, .4962
[13:44:01] <zeeshan> thats so weird
[13:44:19] <zeeshan> the numbers are within a thou of each other
[13:44:35] <zeeshan> but the .5" diameter is off by 3-4 thou!
[13:44:46] <Connor> It's further out..
[13:44:51] <Connor> from the spindle..
[13:44:56] <archivist> built up edge
[13:44:56] <Connor> maybe run-out
[13:45:06] <zeeshan> it if was flexing
[13:45:11] <zeeshan> i'd think it'd be bigger, not smaller
[13:45:40] <Connor> you checked for backlash ?
[13:46:12] <zeeshan> yes
[13:46:15] <zeeshan> its within a thou
[13:46:21] <archivist> if it has poor finish it is a sign of built up edge on the tool
[13:46:31] <zeeshan> archivist: seems pretty nice!
[13:46:51] <archivist> I have seen a nice finish from bue too
[13:47:03] <zeeshan> that is a brand new insert btw
[13:47:08] <Connor> Have you enabled backlash compensation to take the remaining out?
[13:47:14] <zeeshan> Connor: yes
[13:47:22] <archivist> lubricate while testing again
[13:47:30] <zeeshan> archivist: good idea!
[13:47:32] <zeeshan> i didnt think of that.
[13:47:34] <zeeshan> brb
[13:47:44] <zeeshan> i'm tired of making this steps btw
[13:47:47] <Connor> I would take a sprint pass too
[13:47:48] <zeeshan> wasting aluminum ;p
[13:47:53] <Connor> spring
[13:47:59] <jdh> or two
[13:48:05] <Connor> yup. or two.
[13:48:06] <zeeshan> yes, but the thing is
[13:48:09] <zeeshan> it's smaller then nominal!
[13:48:21] <zeeshan> so the spring pass will eat even more material if anything
[13:48:32] <jdh> but it will be prettier.
[13:48:37] <jdh> and that's why we have tolerances.
[13:48:48] <archivist> look at the tip, anything stuck on it?
[13:48:56] <zeeshan> yes, an upcoming project requires bearing fits
[13:48:57] <Connor> once you can get it making them consistent.. you can the compensate for that..
[13:49:01] <zeeshan> so it needs to be within a couple tenths
[13:49:09] <zeeshan> if this thing is really that off, ill just program it to be 1 thou bigger
[13:49:10] <jdh> is your zero good? spindle/way alignment?
[13:49:12] <zeeshan> so i can sand it to size
[13:49:25] <zeeshan> jdh, yes zero is good
[13:49:34] <zeeshan> i havent checked spindle/way alignment
[13:49:42] <zeeshan> it could actually be that
[13:49:47] <zeeshan> since it's consitently off in the same location
[14:41:11] <zeeshan> http://i.imgur.com/El0rabJ.png
[14:41:18] <zeeshan> i wonder what would be a good tool to use for this type of part
[14:41:25] <zeeshan> iscar grooving/turning tool?
[14:44:37] <Tom_itx> is that a thread form?
[14:44:46] <zeeshan> yea
[14:44:50] <zeeshan> thats not the issue though
[14:44:53] <zeeshan> i have a tool for that
[14:44:54] <zeeshan> the middle part
[14:45:03] <Tom_itx> roll thread
[14:45:19] <Tom_itx> i've done that quite a bit... they turn out quite nice
[14:45:38] <zeeshan> what do you mean roll thread
[14:45:42] <zeeshan> you want me to form the threads?
[14:45:58] <Tom_itx> we did that alot in brass fittings
[14:46:15] <Tom_itx> double roller thread roll
[14:46:50] <Tom_itx> you _could_ use a single bump roll
[14:50:23] <zeeshan> question for you guys
[14:50:29] <zeeshan> when doing a threading cycle on the lathe
[14:51:00] <zeeshan> does g76 automatically ensure that one side of trhe insert cuts?
[14:51:42] <cradek> read about "Q":
http://www.linuxcnc.org/docs/html/gcode/gcode.html#sec:G76-Threading-Canned
[14:52:17] <zeeshan> sweet :D
[14:53:22] <zeeshan> im an idiot, how did i mess q
[14:53:24] <zeeshan> miss q.
[14:53:24] <zeeshan> :D
[14:57:01] <Tom_itx> how are you cutting the relief?
[14:58:29] <Tom_itx> yeah a small grooving tool would do that
[14:58:55] <Tom_itx> we did alot of internal reliefs that way
[15:53:26] <JT-Shop> the plasma is going on a diet!
[16:04:12] <Jymmm> Ionized water and nitrogen?
[16:07:45] <SpeedEvil> Jymmm: Water soluble cutting fluid.
[16:08:04] <Jymmm> in a plasma?
[16:08:45] * JT-Shop goes to see if the DX32 chokes on 3500 lines of G code
[16:09:22] <CaptHindsight> Jymmm: yes, all cores
[16:09:39] <Jymmm> CaptHindsight: As SMP?
[16:15:53] <CaptHindsight> Jymmm: yes, if you mean symmetrical multiprocessor vs sam monkey peanut
[16:16:15] <Jymmm> =)
[16:17:43] <PCW> mmm peanuts
[16:18:39] <CaptHindsight> but I just tried to reboot a wheezy 3.4-5 pae RTAI machine and the kernel log shows a hardlock on core 3 and keeps trying to shutdown, first time it's happened
[16:19:15] <sharpen047> hey guys, would anyone be able to help me get an embedded video in EMC? i have m player working but would like the offset save as well
[16:20:20] <CaptHindsight> sharpen047: do you refer to the camview stuff for Axis?
[16:20:41] <sharpen047> yes, camview doesnt work. mplayer does
[16:20:50] <sharpen047> i get a shared memory error
[16:21:03] <CaptHindsight> sharpen047: what OS and kernel?
[16:21:25] <sharpen047> ubuntu 10.04 and let me double check.
[16:21:25] <CaptHindsight> ubuntu version #? or is this on wheezy?
[16:22:58] <CaptHindsight> I'm working on the fixed howto for that on the wiki
http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Adding_Camview
[16:22:59] <sharpen047> lucid. 2.6.32
[16:23:16] <sharpen047> oh youre changing it?
[16:23:16] <CaptHindsight> it's a mess
[16:23:40] <sharpen047> no comment :) but youre basically famous!
[16:23:55] <CaptHindsight> well it works but howto get it working is fragmented over 5-6 wiki pages and 10 messages on the mail list
[16:24:23] <sharpen047> im going to attempt to log into freenode on the cnc computer as sharpen048
[16:24:39] <CaptHindsight> I can't help right now
[16:24:59] <CaptHindsight> but I was planning on getting this all straighten out over the next few days
[16:26:43] <sharpen048> alrighty CaptHindsight
[16:27:18] <sharpen048> what would you like to know about the system?
[16:31:58] <sharpen048> video card fan isnt on ugh
[16:37:31] <CaptHindsight> I can't help right now
[16:37:40] <CaptHindsight> but I was planning on getting this all straighten out over the next few days
[16:37:41] <sharpen047> alright. ill keep checking then.
[16:37:48] <sharpen047> thanks
[16:37:58] <CaptHindsight> straightened
[16:38:06] <CaptHindsight> it a mess isn't it?
[16:38:14] <CaptHindsight> it's even
[16:38:28] <sharpen047> haha yes it is. i have 6 tabs open for it atm
[16:38:40] <sharpen047> i cant tell which part is which either.
[16:38:57] <CaptHindsight> you need his (psha's) packages
[16:39:15] <sharpen047> i have them, in the ini folder for the machine.
[16:39:23] <CaptHindsight> and it has a file hosted on his site Use this version of halio.c: upload:halio.c
[16:39:25] <sharpen047> camview is the problem
[16:39:32] <CaptHindsight> http://wiki.linuxcnc.org/uploads/halio.c
[16:39:39] <sharpen047> i cant open camview to set up a chain
[16:40:05] <sharpen047> it tells me there is a shared memory problem and that i need 9 more bits
[16:40:24] <CaptHindsight> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Adding_Digital_Zoom_To_Camview-Emc thee is some info here, but I haven't rewritten it yet
[16:40:47] <CaptHindsight> ah 9bit bytes! I should have patented that back in the 80's! :)
[16:41:13] <CaptHindsight> bbl
[16:41:57] <Deejay> gn8
[16:42:09] <sharpen047> later thanks for the help haha
[16:44:07] <Jymmm> WTF?! Can't get xylene, or napatha at home depot in Calif now???
[16:44:25] <syyl> whats it used for?
[16:44:29] <syyl> making napalm?
[16:44:35] <Jymmm> they're solvents
[16:44:55] <syyl> ah ok
[16:45:04] <Jymmm> Even "MEK substitute" now *sigh*
[16:46:18] <CaptHindsight> yeah, silly
[16:46:22] <sharpen048> RTAPI: Locked memory limit is 10240KiB, recommended at least 20480KiB.
[16:46:51] <sharpen048> but root# ulimit -l 40960
[16:47:40] <CaptHindsight> sharpen047: when you use a installer CD from Linuxcnc it sets up the memory limits
[16:48:05] <CaptHindsight> when you install from scratch it's a common oversight
[16:49:08] <sharpen048> i reset it
[16:49:13] <sharpen048> its 40960
[16:49:22] <sharpen048> 20480 is half as much
[17:14:50] <CaptHindsight> sharpen047: does it work now?
[17:18:35] <sharpen048> i got it to work but changing camview-emc -C to -w
[17:18:51] <sharpen048> the buttons dont work and say failed to open "buttonnamehere"
[17:19:01] <sharpen048> like camon or camoff
[17:19:18] <sharpen048> camera works. has about a 2 second delay but i can live with it
[17:20:35] <CaptHindsight> sharpen047: care to write up the procedure for installing and config?
[17:20:54] <CaptHindsight> I'll edit it, add to and put it on the wiki
[17:21:10] <CaptHindsight> any clear info is helpful :)
[17:21:25] <CaptHindsight> on one page even better
[17:23:16] <sharpen048> i just followed instructions by bonny. if i get the buttons to work i can fix the spelling errors haha
[17:26:33] <CaptHindsight> sharpen047: the bottom half of this page?
http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Axis_Embed_Video
[17:26:37] <sharpen048> so far the instructions are hard to follow but i dont have working buttons so it isnt much better than just mplayer
[17:27:21] <sharpen048> yes, "and this is way how to get it. "
[17:27:32] <CaptHindsight> lol
[17:28:22] <sharpen048> theres stuff like that all over the place in there.
[17:30:18] <sharpen048> CaptHindsight: i wouldnt mind rewiting it if i had working buttons. let me work on the buttons and get back to you
[17:35:46] <sharpen048> CaptHindsight: And we need to make another HAL file (campins.hal in zip file) for cam support<--- not sure what this means? we need to make a hal file? isnt it already in the zip file?
[17:37:58] <CaptHindsight> uh huh? :)
[17:38:49] <CaptHindsight> "In my mind"....
[17:39:30] <sharpen048> did you write that stuff?
[17:39:42] <JesusAlos> hi
[17:40:35] <CaptHindsight> sharpen048: I started editing this page
http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Adding_Camview
[17:40:41] <JesusAlos> I have a lott noise problems when put on the inverter of spindle
[17:42:07] <JesusAlos> there are a interface lpt inmunizate noise?
[17:42:28] <sharpen048> JesusAlos: what stepper controller are you using?
[17:42:50] <JesusAlos> use leadshine and RTA
[17:43:18] <JesusAlos> but only appear noise when start inverter
[17:44:04] <JesusAlos> and attacks to joints 0,1,2 and Estop
[17:51:28] <sharpen048> CaptHindsight: i cant figure out why its not wanting to open the files. i press the button like save xyz and it says cant open _camstore
[18:02:04] <PCW> VFD inverters are great noise generators with 350V square waves outputs and current spike driven ground bumping
[18:03:37] <PCW> line filter on VFD power, common mode choke on motor wires can help
[18:04:55] <CaptHindsight> wow, 30-45 degrees of movement by hand and these nema23 steppers are putting out >24V
[18:05:34] <Jymmm> CaptHindsight: wire two togehter. turn one, the other turns too
[18:05:57] <CaptHindsight> power one from another, sure
[18:06:26] <CaptHindsight> put them in a circle and it's perpetual motion :)
[18:06:48] <Jymmm> try it
[18:07:22] <CaptHindsight> I wonder what the back emf is on these at 1k rpm?
[18:08:12] <sharpen048> i used a nema 17 for a speedo for my car :P
[18:11:12] <zeeshan> anyone have experience with vnmg inserts?
[18:11:25] <zeeshan> vcmt and vnmg ,main difference is the clearance angle at the front
[18:11:35] <zeeshan> n has 0 clearance angle, and c has 7 deg.
[18:11:50] <zeeshan> i have a holder that holds vnmg inserts, but i only have vcmt inserts
[18:12:01] <zeeshan> i dont see why the vcmt insert wont work in the vnmg holder :P
[18:12:11] <zeeshan> or am i missing something.
[18:14:57] <sharpen048> CaptHindsight: may have fixed buttons
[18:15:38] <JesusAlos> i found this interface
[18:15:40] <JesusAlos> http://benezan-electronics.de/shop/popup_image.php?pID=51
[18:15:50] <JesusAlos> it seems good
[18:15:59] <JesusAlos> any body use it?
[18:16:38] <sharpen048> CaptHindsight: nevermind. no output whatsoever
[18:28:28] <CaptHindsight> yikenzie! 264,70€ for a LPT breakout board?
http://benezan-electronics.de/shop/product_info.php?cPath=1_4&products_id=61&language=de
[18:29:52] <CaptHindsight> JesusAlos: you can find others that work fine for less
[18:31:45] <JesusAlos> CaptHindsight: as what? please
[18:31:49] <gonzo_nb> rops_nogs
[18:31:58] <gonzo_nb> shrops
[18:32:24] <gonzo_nb> ugh, whong chan
[18:32:40] <gonzo_nb> wrong
[18:33:00] <CaptHindsight> JesusAlos: do you need the spindle support or just Step, Direction and some IO for limit and home switches?
[18:34:25] <sharpen048> CaptHindsight: now i get "all axes missing with g92"
[18:34:48] <JesusAlos> CaptHindsight: yes 0,1,2 and Estop inputs. 3 axis step direction outputs and 0-10V for spindle
[18:36:29] <CaptHindsight> JesusAlos:
http://www.ebay.com/itm/310702269807
[18:37:57] <CaptHindsight> http://www.ebay.com/itm/111149514180
[18:39:23] <JesusAlos> I was try this last option
[18:39:35] <JesusAlos> and was several noise problems too
[18:40:36] <CaptHindsight> the documentation is terrible
[18:42:44] <JesusAlos> I see the difference of price but the benezan-electronics board seems very inmunized noise
[18:42:47] <sharpen048> which one haha
[18:44:25] <JesusAlos> I'm off
[18:44:27] <JesusAlos> thank
[18:44:33] <JesusAlos> by
[18:58:15] * LeelooMinai scratches the head
[19:00:25] <LeelooMinai> I am making a place in my room for cnc machine and floor drill - it will be just 6x 10ft long cedar 2 by 6. Not sure about the weights, but the floor drill is a medium size I guess, and the cnc will weight maybe, hmmm, 60kg? Should I worry I put those two by the wall?
[19:01:01] <LeelooMinai> I guess people put heavy aquarium and such in rooms... so maybe I should not worry too much?
[19:03:00] <chris33> h im going to be using a tb6560 controller for my shapeoko and i want use linux but i want run it from a sbc like a pi or beagleboard has anyone modded a pi or similar and added a parallel port to one
[19:03:34] <JT-Shop> there is a beagleboard section on the forum
[19:03:51] <sharpen048> ok CaptHindsight i found that the hal file isnt opening buttons
[19:04:45] <LeelooMinai> Hmm found spec for the drill - 151 pounds - I guess that's nothing I should worry about, right?
[19:05:00] <JT-Shop> how much do you weigh?
[19:05:17] <LeelooMinai> No idea:)
[19:05:59] <LeelooMinai> I googled that there's some standard of 40 punds per square feet load for normal homes
[19:06:22] <LeelooMinai> But it may be average, not point load (?)
[19:06:41] <LeelooMinai> Well, it must be, because otherwise a person would make a hole in the floor...
[19:06:47] <JT-Shop> heh
[19:07:06] <JT-Shop> jump up and down and if the floor doens't collapse your oke
[19:07:23] <zeeshan> http://img.auctiva.com/imgdata/1/4/2/8/7/3/9/webimg/688147512_o.jpg
[19:07:29] <zeeshan> whats the point of the thing that goes below the insert?
[19:07:33] <LeelooMinai> Unfortunatelly those 2x6 cedar planks I have will be parallel to joists not across them
[19:07:36] <zeeshan> i never had this on my old tool holders
[19:08:27] <JT-Shop> it provides support for the insert and when you crash you can replace it
[19:08:55] <zeeshan> so its a bumper
[19:08:57] <LeelooMinai> btw, did anyone here do something for cnc (say small table with inserts) from concrete?
[19:08:57] <zeeshan> :D
[19:09:37] <LeelooMinai> I read about kitchen countertops people make from concrete and though if this could be used somehow for cnc table - as it's dirt cheap
[19:11:44] <JT-Shop> some use granite with epoxy
[19:12:28] <LeelooMinai> Hmm, that may be not as cheap as concrete probably
[19:13:00] <sharpen048> anyone else familliar with camview?>
[19:13:45] <sharpen048> or ui files for that matter
[19:15:14] <JT-Shop> ui?
[19:16:02] <sharpen048> im trying to add buttons to axis
[19:16:13] <sharpen048> trying to get offsets to work with camview addon
[19:24:49] <sharpen048> ahh i am so lost
[19:25:16] * Jymmm hands sharpen048 two sticks to rub together
[19:25:25] <sharpen048> haha
[19:25:37] <sharpen048> all these attachments dont work correctly.
[19:26:12] <Jymmm> sharpen048: It's like a mixer, only one at a time.
[19:26:28] <sharpen048> care to try?
[19:26:41] <sharpen048> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Axis_Embed_Video
[19:27:01] <sharpen048> at the bottom there is a menu option set you download and install in the ini folder
[19:28:53] <sharpen048> reboot be right back
[19:31:48] <sharpen047> Jymmm: ok back]
[19:32:12] <Jymmm> sharpen047: Got the fire started yet?
[19:33:13] <sharpen047> haha, nope nothing
[19:33:47] <Jymmm> sharpen047: Ok, grab two gallons of gas and a road flare
[19:34:19] <Jymmm> sharpen047: ...also, if you have any bars of magnesium
[19:34:30] <sharpen047> flint is all i have
[19:34:46] <Jymmm> steel wool and a car battery?
[19:35:16] <Jymmm> wooden pencil, toilet paper, and a 120V outlet?
[19:36:16] <Jymmm> sulfur, potasium nitrate, and carbon?
[19:41:39] <Jymmm> Calcium hypochlorite and brake fluid?

[19:42:58] <zeeshan> i wonder if this is a good deal
[20:06:40] <PetefromTn_andro> Good evening folks.
[20:11:28] <sharpen047> does anyone know how to get the camera offsets to work in emc?
[20:16:50] <Valen> we wrote them on the whiteboard next to the mill then do the maths ;->
[21:09:33] <os1r1s> Tom_itx: You around?
[21:42:11] <archivist> zeeshan, common on screw cutting tools to modify the lean/angle of the tip for screw cutting
[21:43:40] <zeeshan> archivist: yes
[21:43:54] <zeeshan> archivist: do you have a morse taper quick change tool holder for your quick change tool post?
[21:44:07] <archivist> no
[21:44:21] <zeeshan> ;/
[21:45:01] <zeeshan> http://www.accusizetools.com/0250-0205-7-8-2mt-bxa-morse-taper-holder/
[21:45:03] <jdh> I have a jacobs chuck that fits mine. not a morse though
[21:45:13] <zeeshan> i dont understand
[21:45:18] <zeeshan> how this thing holds mt2 mt3 mt4 ?
[21:45:25] <zeeshan> or any taper to begin with!
[21:45:33] <zeeshan> looks like they have the wrong pic..
[21:45:46] <XXCoder> https://www.youtube.com/watch?feature=player_embedded&v=VjE0Kdfos4Y#t=114
[21:45:51] <zeeshan> but regardless, i dont see how it holds 3 different tapers
[21:45:53] <zeeshan> with the same holder
[21:46:06] <XXCoder> hammer makes everything fit heh
[21:46:39] <Connor> zeeshan: The sleeve insert.
[21:46:58] <zeeshan> hm
[21:47:06] <zeeshan> so the holder without any sleeve is mt4
[21:47:09] <zeeshan> and they you can step it down to mt2?
[21:47:14] <zeeshan> *they = then
[21:47:56] <Connor> I dunno
[21:48:04] <archivist> not sure my toolpost is big enough
[21:48:23] <Connor> Wouldn't think the sleeves would be accurate enough though..
[21:48:29] <zeeshan> yea
[21:48:44] <Connor> That looks more like a boring bar holder to me..
[21:48:49] <Connor> But, I dunno.
[21:48:54] <zeeshan> im pretty sure its the wrong pic
[21:48:58] <zeeshan> cause it doesnt match up with the other ones
[21:49:05] <zeeshan> theres 2 top set screws in that sleeve pic
[21:49:08] <zeeshan> but they dont exist in the other pics
[21:49:35] <Connor> look at the PDF
[21:49:44] <zeeshan> yea
[21:49:48] <zeeshan> it says 2mt..
[21:49:58] <zeeshan> i guess if im doing really big drilling
[21:50:01] <zeeshan> i'll just use the tail stock
[21:50:22] <Connor> That pic with the sleeve is the heavy duty boring bar holder.
[21:51:19] <Connor> What is a USA Style QTC post ?
[21:51:31] <zeeshan> basically means itll fit aloris tool posts
[21:51:35] <zeeshan> or dorian
[21:51:45] <zeeshan> ok bed time!
[22:22:39] <RyanS> http://www.tormach.com/blog/tts-superfly-cutters-a-modern-update-to-an-old-shop-standard/ I'm trying to understand paragraphs 5 and six, how is the power divided equally amongst each tip? I didn't think there would be the same amount of load on each tip simultaneously
[22:23:33] <XXCoder> captioned nice
[22:25:48] <XXCoder> bellows cover cover lol
[22:26:38] <RyanS> what
[22:27:02] <XXCoder> thats what guy in video said about that cover that covers Y bellows cover
[22:28:11] <RyanS> so you don't have to brush all chips from the creases
[22:28:15] <XXCoder> indeed
[22:28:40] <XXCoder> "they look hot" "lets grab some to show" lol
[22:29:57] <XXCoder> awesome though. its fairly rare to see cpations
[22:30:02] <RyanS> everyone likes hot chips :)
[22:30:02] <XXCoder> expecially on that subject
[22:30:24] <XXCoder> so if I added hot sauce on those hot chips, would it be hot hot chips?
[22:31:33] <RyanS> Now you are making my joke even worse
[22:31:55] <XXCoder> I know. o have dad jokes even though I has no kids lol
[22:33:51] <FinboySlick> Just had a look, he seems to be cutting relatively deep on the trailing end when he's on the steel block, makes me wonder how well the head is trammed.
[22:34:31] <RyanS> Does it make sense that a single point cutter outperforms face mill considering it's a small machine
[22:34:57] <Valen> does make a nice sound on that first pass
[22:36:14] <RyanS> Only thing with this machine is I will have to use a step down transformer because it's 115v
[22:38:13] <Valen> is he selling the cover cover?
[22:38:28] <RyanS> who
[22:38:35] <Valen> i mean they get as much focus as the fly cutter
[22:39:06] <RyanS> It's a bit hard to focus on a spinning object :)
[22:39:14] <Valen> lol
[22:39:59] <RyanS> Paradoxically, they sell one of these
http://www.tormach.com/store/index.php?app=ecom&ns=catshow&ref=multicat_modinsert_facemill_38mm at a rip-off price. However
[22:51:26] <RyanS> Valen , how many tools do you typically find yourself using for any one CNC job? gets expensive with around a dozen toolholders
[22:52:00] <Valen> we don't have toolholders
[22:52:07] <Valen> just a ER something chuck
[22:52:16] <Valen> an ATC would be a boon to us ;->
[22:52:36] <Valen> so we go to great lengths to minimise tool changes lol
[22:53:36] <Tom_itx> manual is a big pita
[22:57:42] <RyanS> When I finally muster up enough courage or stupidity to buy a tormach 770 im] going for a pneumatic drawbar
[22:58:16] <Valen> we are going to make a new spindle
[22:58:26] <Valen> it will have some form of ATC
[22:58:46] <RyanS> The ATC is out of the question, far too expensive
[22:59:14] <RyanS> I don't have the knowledge to design one myself
[23:00:04] <RyanS> Besides, do I really want to leave the machine unattended.... I don't think so
[23:12:53] <Valen> eh, doesn't matter too much really
[23:13:23] <Valen> but there is unateended and there is it can do everything without me screwing with it every 5 minuted
