[00:27:57] <PCW> well hard drive next
[00:28:26] <Tom_itx> reseat all the connectors
[00:28:28] <sharpen047> ok, how would i test that? i figured XP works and low graphics works?
[00:28:29] <sharpen047> ok
[00:30:47] <sharpen047> same thing. hangs at cursor
[00:31:19] <sharpen047> unplugged cd rom, disabled onboard LAN, took out wifi and par port card
[00:32:31] <sharpen047> seems like a window manager issue almost.
[00:33:50] <asah> sharpen047: can you boot into console mode?
[00:34:04] <sharpen047> yes
[00:34:19] <asah> can you hit ctrl+alt+F4
[00:34:31] <asah> or F1 etc and get a console?
[00:34:44] -!- PCW has quit [Quit: ChatZilla [Firefox 31.0/20140716183446]]
[00:34:49] <sharpen047> doesnt respond if i boot and it hangs but i have the failsafe option in grub
[00:35:06] <asah> so boot untill cursor freezes, then try and view the boot log, or get into a console and check ps ?
[00:35:09] <asah> ah ok.
[00:35:13] <asah> thats unfun.
[00:35:24] <asah> whats the os? ubu 10?
[00:35:39] <sharpen047> im not sure actually. 10 or 12
[00:35:44] <sharpen047> i think 10
[00:36:05] <asah> was this a result of an auto update or any new software packages?
[00:36:10] <asah> potentially?
[00:36:23] <sharpen047> possibly yes
[00:36:38] -!- acdha has quit [Client Quit]
[00:36:53] <sharpen047> it has a bunch it wants to update now
[00:37:13] <asah> can you do: lsb_release -a
[00:38:12] <sharpen047> 10.04
[00:38:21] <asah> 32bit?
[00:38:28] <asah> (probably)
[00:38:31] <sharpen047> yes its a single core amd
[00:38:38] <asah> uname -a
[00:39:16] <asah> we just had a similar issue on an older 12.04 32bit laptop, two days ago.
[00:39:17] <sharpen047> 2.6.32
[00:39:19] <asah> was a repo problem.
[00:39:32] <sharpen047> they support 12?
[00:39:32] <asah> gimme a sec to call my friend.
[00:40:05] <sharpen047> thanks!
[00:41:10] <sharpen047> but again the failsafe graphics mode it boots fine and runs

[00:45:40] -!- amiri_ has quit [Read error: Connection reset by peer]
[00:46:13] <asah> ok, so yes, our issue was nvidia driver update borked system is sameish way
[00:47:23] <asah> the fix was one of: use the bumblebee project to get updated nvidia drivers backported, but you could likely just download new ones and install direct from nvidia as bumblebee doesn’t support 10.
[00:47:45] <asah> other thing he did was to disable all unused serial ports and usb ports in the bios.
[00:48:03] <asah> there seems to be interrupt contention issues with this particular driver combo?
[00:48:07] -!- PetefromTn_ has quit [Quit: I'm Outta here!!]
[00:48:46] <asah> this may be goose chase land, but we had exactly the same symptoms and it happened to us only a few days ago on an older ubu 12 32bit os with an nvidia.
[00:48:49] <sharpen047> what would i do? i dont have any other ports enabled on the bios except the usb ports because i use them
[00:49:09] <sharpen047> which would explain why safe graphics mode works
[00:49:46] <archivist> you can try to dump nvidia drivers and use the generic ones
[00:50:20] <sharpen047> ok ill boot in safe mode and reconfig video
[00:50:28] <sharpen047> although NV drivers mess with realtime anyway
[00:51:38] -!- acdha has quit [Client Quit]
[00:52:47] <asah> if that doesn’t work you can google the ubu-x-swat ppa which has the latest nvidia bits.
[00:52:55] <XXCoder1> damn thats weird surivied crash
[00:53:21] <asah> sudo apt-add-repository ppa:ubuntu-x-swat/x-updates && sudo apt-get update
[00:53:31] <XXCoder1> wrong channel
[00:53:32] <asah> sudo apt-get install nvidia-current nvidia-settings
[00:53:51] <asah> etc...
[00:53:53] <sharpen047> asah it wont let me reconfig video
[00:54:29] <asah> do you see any nvidia drivers installed as packages?
[00:54:39] <asah> dpkg -l |grep -i nvidia
[00:55:09] <sharpen047> asah, i can see part of dmesg. it gave me an erorr list for video devices
[00:55:17] <sharpen047> nouveau is the error
[00:55:35] <sharpen047> EDID error
[00:56:32] <asah> I would remove nouveau
[00:56:38] <asah> and install nvidia-current
[00:57:59] <sharpen047> how do i search for the package install again? sorry havent used console in a while.
[00:59:40] <asah> search for installed packages?
[00:59:48] <asah> dpkg -l |grep -i nvidia
[00:59:52] <asah> will look for nvidia
[01:00:25] <asah> thats a lowercase L on dpkg
[01:00:34] -!- swingley has quit [Ping timeout: 264 seconds]
[01:01:35] <sharpen047> so nouveau1 and xorg video nouveau is installed
[01:02:57] <asah> sudo apt-get remove —purge nvidia*
[01:03:22] <asah> sudo apt-get remove —purge xorg-video-nouveau
[01:04:24] <sharpen047> two - at purge i take it?
[01:04:36] <asah> yes
[01:04:55] -!- Tecan has quit [Quit: Live Long And Phosphor!]
[01:06:10] <sharpen047> cant find xorg-video-nouveau
[01:06:32] <asah> then I would do the ppa lines above so you can get the nvidia binary drivers
[01:06:38] -!- acdha has quit [Client Quit]
[01:06:53] <asah> what is the name of the nouveau packages you found from dpkg -l ?
[01:06:56] <sharpen047> xserver-xorg etc
[01:07:05] <asah> don’t kill xserver-xorg
[01:07:11] <asah> obviously.
[01:07:12] <asah> =)
[01:07:17] <asah> thats a longer reinstall.
[01:07:26] <sharpen047> theres a nouveau for it
[01:07:38] <asah> called xserver-xorg-nouveau ?
[01:07:46] <sharpen047> xserver-xorg-video-nouveau
[01:07:53] <asah> yeah, uninstall that one.
[01:07:59] <sharpen047> done
[01:08:10] <asah> reboot. see what happens.
[01:08:43] <asah> you can check to see if the kernel module gets loaded with : lsmod | grep nouveau
[01:09:24] <sharpen047> giant 480x360 res haha or something
[01:09:31] <asah> =)
[01:09:35] <sharpen047> monitor doesnt support this resolution im guessing
[01:09:54] <asah> well, you don’t have a very good driver anymore =)
[01:09:58] <asah> now to install the nvidia bits.
[01:10:06] <asah> udo apt-add-repository ppa:ubuntu-x-swat/x-updates && sudo apt-get update
[01:10:08] <sharpen047> it doesnt seem like a good one i gues haha
[01:10:12] <sharpen047> ok let me reboot again
[01:11:47] <sharpen047> ok no video output
[01:12:42] <sharpen047> i cant even get a console
[01:13:22] <asah> can you safe/console boot?
[01:13:52] <asah> do you have another graphics port on this computer?
[01:14:01] <asah> like on the motherboard?
[01:14:03] <sharpen047> i do not have another port
[01:14:28] <sharpen047> i cant see anything past the driver loading messages
[01:14:35] <sharpen047> i may have an old CRT
[01:14:35] <sharpen047> brb
[01:15:59] <sharpen047> wow my lights dimmed when i plugged in this 15" crt
[01:16:22] <asah> =)
[01:16:44] <asah> I saw a land line phone in a movie recently. pretty weird how quickly times change.
[01:17:13] tjb11 is now known as tjb1
[01:17:30] <jdh> i still have house phones
[01:17:32] <sharpen047> crt shows no video output either
[01:17:41] <sharpen047> haha we have house phones as well
[01:17:59] <sharpen047> red light so its in sleep mode on monitor
[01:17:59] <jdh> but they are hooked up to a cell device
[01:18:00] <asah> ok, thats a bad reference then. =)
[01:18:16] <asah> if you moved would you install a landline again?
[01:18:19] <sharpen047> still responds to ctrl alt del
[01:18:28] <sharpen047> now what?
[01:18:29] <asah> (I moved recently, and decided not to… anyway)
[01:18:42] <asah> so you have no way to get a console up?
[01:18:42] <sharpen047> use grub for a command line?
[01:18:50] -!- mhaberler has quit [Quit: mhaberler]
[01:18:58] <asah> yeah, boot without graphics.
[01:19:05] <jdh> I wont answer mine.
[01:19:05] <asah> alternate grub entry
[01:19:28] <sharpen047> hm, how would i do that?
[01:19:42] <asah> what options do you have in grub?
[01:20:25] <sharpen047> e to edit commands before booting
[01:20:31] <sharpen047> c for a grub command line
[01:21:17] <asah> how were you “safe mode” booting before?
[01:21:37] -!- acdha has quit [Client Quit]
[01:22:18] <asah> what is the video line you get out of e ?
[01:22:54] -!- sirdancealot has quit [Ping timeout: 250 seconds]
[01:22:56] <sharpen047> it was an option for recovery mode on this kernel
[01:23:09] <asah> and does that boot for you?
[01:23:09] <sharpen047> but this one lets me edit the grub entry before boot
[01:23:18] <sharpen047> it boots but doesnt put out video
[01:23:35] <sharpen047> anything past usb driver loading
[01:24:07] <asah> that is what you get in “recovery mode” ?
[01:24:08] <sharpen047> let me see if i can ctrl alt bspc
[01:24:23] <sharpen047> yes i get that either way
[01:24:23] <asah> what about ctrl alt F1 to get a console up
[01:24:51] <sharpen047> cursor then loads anyway and no output at all from videwo
[01:24:55] <sharpen047> video card
[01:26:29] <asah> grub console should get you going.
[01:27:50] <asah> you need the equiv of GRUB_TERMINAL=console in the grub prompt.
[01:28:00] <asah> (haven’t had to do this in a while thankfully)
[01:28:30] <sharpen047> well im not sure
[01:28:33] <asah> if you do hit e, what do you see?
[01:28:35] <sharpen047> would another video card work?
[01:28:41] <asah> what is the current grub line trying to setup?
[01:28:55] <sharpen047> says grub_console
[01:29:24] -!- Servos4ever has quit [Quit: ChatZilla [SeaMonkey 2.26.1/20140612173529]]
[01:29:33] <sharpen047> grub>
[01:29:40] <asah> what about the e option, that should allow you to edit the grub entry that is currently booting into borked video mode
[01:29:55] <asah> when you do hit e, what grub options are there?
[01:29:56] <sharpen047> right
[01:30:08] <sharpen047> its stuff likeinsmod ext2
[01:30:16] <sharpen047> vmlinuz oiptions
[01:30:19] <asah> GRUB_GFXMODE etc...
[01:30:27] <asah> things like resolutions
[01:30:34] <asah> 800x600x32 etc.
[01:31:26] <sharpen047> i dont see that
[01:31:48] <sharpen047> emacs loading is supported
[01:32:25] <sharpen047> it says at the bottom it is anyway.
[01:33:53] <asah> what is a video mode you know works on your display?
[01:33:57] <asah> 800x600 ?

[01:36:37] -!- acdha has quit [Client Quit]
[01:36:54] <asah> which version of grub? 2 ?
[01:39:25] <Jymmm> 2.1 The sequel
[01:42:36] <asah> add a gfxmode=800x600 line in the linux section
[01:45:42] <sharpen047> asah: 800x600 should work. i have a CRT and a 1080 display here. if it puts anything above 480 i should be fine lol

[01:46:00] <sharpen047> which part is linux section
[01:46:23] <asah> there should be the word “linux” and a bunch of stuff.
[01:46:27] <asah> put it on the next line
[01:47:54] <sharpen047> same thing
[01:48:32] <asah> ok, found another: GRUB_GFXPAYLOAD_LINUX=text
[01:48:41] <asah> do that instead of the gfxmode line
[01:49:11] <Jymmm> Is "nosplash" no longer an option in GRUB2 ?
[01:49:14] <asah> sorry, thats the config var.
[01:49:22] <sharpen047> its here so yes
[01:49:25] <asah> gfxpayload=text
[01:50:16] <sharpen047> same thing
[01:50:29] <asah> fun times.
[01:50:36] <asah> you have another gfx card?
[01:50:43] <sharpen047> yes
[01:51:17] <sharpen047> i have a pile going to goodwill
[01:51:22] <sharpen047> im taking a ton of parts from it
[01:51:29] <Jymmm> Did you : sudo update-grub
[01:51:34] <Jymmm> after updating the file?
[01:51:55] <asah> Jymmm: he can’t get into linux
[01:51:58] <asah> stuck at grub
[01:52:50] <asah> ok. so looking at my /boot/grub/grub.cfg the proper syntax should be “gfxmode text” no quotes and before linux line
[01:53:03] <Jymmm> Boot from a LiveCD and see if you can go from there
[01:53:04] <asah> and before the insmod lines
[01:53:39] <sharpen047> pci based card vs ago
[01:53:43] <sharpen047> agp
[01:53:59] <sharpen047> same thing no video
[01:54:10] <sharpen047> ill start dling new linux cnc cd anyway
[01:54:24] <Jymmm> sharpen047: No video when booting from a LiveCD?
[01:55:17] <sharpen047> i dont have a livecd with me. ill download one now.
[01:55:23] <sharpen047> oh right, i dont have cds
[01:55:34] <sharpen047> USB drive it is
[01:55:37] <Jymmm> Well, a LiveUSB then
[01:55:53] <Jymmm> how old is this box?
[01:55:54] <sharpen047> oh wait. thats what i use to transfer cnc files
[01:56:17] <sharpen047> its an athlon xp. so quite old. since emc doesnt work on multocore computers very well
[01:57:18] <asah> man… sorry, killing your vid drivers should still allow you to boot textmode. =(
[01:57:26] <Jymmm> That's not necessarily true, but ok.
[01:57:42] <Jymmm> It just doens't take advantage of them is all
[01:58:22] <sharpen047> no prob. as far as i see it, i didnt have a working system anyway
[01:58:37] <sharpen047> now to see if it supports usb boot
[01:58:48] <Jymmm> heh
[01:59:37] <sharpen047> ok it booted from the usb
[01:59:47] <sharpen047> its ubuntu, not sure which version
[01:59:54] <asah> Jymmm: I have like 5 headless linux boxes sitting around doing stuff.
[02:00:17] <sharpen047> "try ubuntu" yep
[02:00:30] <Jymmm> sharpen047: I have one box with bunch of VM's running =)
[02:00:49] <sharpen047> good video on this livecd
[02:01:19] <sharpen047> with the slow vid card. i have a "nice" 64 meg video card which is what i removed haha
[02:01:25] <Jymmm> sharpen047: Now, when you edit grub again, MAKE A BACKUP *BEFORE* editing =)
[02:01:40] <sharpen047> grub 2 doesnt save them
[02:01:54] <sharpen047> anything i edit is one time only and reverts on reboot
[02:02:01] <asah> he hasn’t been able to get into his linux.
[02:02:11] <asah> he is stuck at grub, editing grub via “e"
[02:02:16] <sharpen047> ok i have a desktop from livecd
[02:02:18] <Jymmm> I don't care, make a backup.
[02:02:35] <Jymmm> It will CYA.
[02:02:36] <sharpen047> oh its linux cnc cool
[02:02:48] <sharpen047> im pretty sure i have a backup
[02:03:03] <sharpen047> i just cant get to it. but the problem is the video drivers
[02:03:31] <Jymmm> Try VESA
[02:03:47] <Jymmm> if that's still an option
[02:04:12] <zeeshan> what driver is used
[02:04:20] <zeeshan> when ubuntu is in "low video mode" or whatever its called
[02:04:25] <sharpen047> i should reboot with the normal card in it
[02:04:36] <sharpen047> none load right now
[02:04:40] <sharpen047> we removed them all
[02:05:37] <asah> well, we should have only removed the nouveau driver.
[02:05:54] <sharpen047> i see that now
[02:05:59] <sharpen047> haha
[02:06:09] <sharpen047> gotta chroot in now
[02:06:12] <asah> what else did you remove ?
[02:06:28] <asah> did you kill xorg?
[02:07:15] -!- syyl_ has quit [Ping timeout: 246 seconds]
[02:07:49] <sharpen047> nouveau and nvidia only
[02:08:35] <asah> ok, that should be fine.
[02:08:45] <asah> weird you can’t get basic modes.
[02:09:38] <asah> you could install the nvidia binary drivers in your chroot
[02:10:28] <sharpen047> iirc nv drivers caused real time errors in emc
[02:12:52] <asah> nv is the non hardware accellerated nvidia driver.
[02:13:01] <asah> nouveau is the open source driver
[02:13:37] <asah> there is a nvidia driver called nvidia which is their binary driver
[02:13:39] <sharpen047> which explains why i wasnt using nvidia drivers
[02:15:51] <sharpen047> wont boot again
[02:16:26] <asah> what did you mod in your chroot?
[02:16:47] -!- micges has quit [Quit: Leaving]
[02:16:57] <sharpen047> nothing. havent gotten live cd up again
[02:17:08] <sharpen047> installed old card. booted with no mouse so i rebooted again
[02:17:23] <sharpen047> keeps locking up at seemingly random spots.
[02:17:34] <asah> lovely.
[02:18:59] <XXCoder1> "I'm sure I has backup" means nope I don't to me lol
[02:20:40] <sharpen047> booting usb on this pc sucks
[02:20:53] <sharpen047> and i know i have a backup but dont know how old it is or if it has this kernel on it

[02:28:08] <asah> intermittent usb functionality?

[02:50:14] <asah> sounds like a fresh install on a new hd might be a good idea.

[03:54:27] <sharpen047> what would you try?
[03:55:00] <asah> I would try the nvidias first. confirm realtime errors, then you could fallback to nv, then to nouveau.
[03:55:15] <asah> that is try the nvidia binary closed source driver.
[03:55:17] <asah> first

[09:51:37] -!- acdha has quit [Client Quit]
[09:52:04] <DarkAlchemist> does that mean I will ruin a board under it? I don't really see how it can help but ruin something unless you could precisely flip it over.
[09:53:17] <SpeedEvil> If you have a largely flat workpiece
[09:53:25] <DarkAlchemist> I am thinking of something like a 2x4 poece of wood under the item I am going to mill but that piece will be all kinds of shot to hell
[09:53:31] <SpeedEvil> Take your spoiler board, and route grooves in it.
[09:53:33] <archivist> it is all in the hands of the user and his jig and how he creates the gcode, there is no one answer for all situations
[09:53:41] <SpeedEvil> Drill into the grooves, not the highs
[09:54:13] <SpeedEvil> err - nvm - that's not a spoiler board
[09:54:17] <archivist> I use packing spacers
[09:54:19] * SpeedEvil is not awake
[09:54:25] <DarkAlchemist> heheh, :)
[09:54:30] <DarkAlchemist> packing spacers?
[09:54:49] <SpeedEvil> If you can fixture the part into the exact same place WRT the spoiler every time - then the drill goes into the same holes
[09:55:25] <DarkAlchemist> yep, but very very hard to do with any sort of repeatability and precision and especially by eye and hand
[09:56:11] <archivist> erm...cnc, very repeatable
[09:56:24] -!- larryone has quit [Ping timeout: 250 seconds]
[09:56:32] <DarkAlchemist> what about some sort of something that would lift the part up by 5mm off of the table but then I wonder when it gets close to the bottom on its final cut around passes?
[09:56:55] <archivist> it is called a spacer/packing
[09:57:18] <DarkAlchemist> the cnc is but putting the object in the precise same spot and making the head come to the exact same spot would require some sort of jig for sure
[09:58:05] <DarkAlchemist> so, lets say the stock is 6061

[09:58:24] <DarkAlchemist> what could I use to lift it up 5mm off of the bed yet it is gripped to work on?
[09:59:03] <DarkAlchemist> only the corners would be lifted so the mill would never touch them

[09:59:10] <archivist> any good metal to hand
[09:59:41] <DarkAlchemist> I think I can make such a jig

[10:02:27] <Loetmichel> re from the landfill/trash power plant... interesting: my car weights exactly 2 tons without me... the papers of the car state 1750kg... it seems i should clean up that pile of junk a bit ;-)
[10:02:40] <archivist> support is dependent on work and cut depth
[10:03:19] <DarkAlchemist> most items will be 10-60mm in depth of various materials
[10:03:53] <DarkAlchemist> so, this is no steel cnc just can do up to Aluminum so shallow passes
[10:04:42] <archivist> if the cut is light enough one gets away with http://www.collection.archivist.info/searchv13.php?searchstr=crossing
[10:04:45] <DarkAlchemist> that is why I was worried as the piece will be free floating in space on that last pass

[10:48:16] <archivist> past close...usable :)
[10:48:42] <Loetmichel> kfoltman: liiks nice. but jou have to get a smaller engraving bit. and/or shift the isolation lines half the tip diameter
[10:49:56] <kfoltman> they're already shifted :) 0.3mm v-bit and 0.8mm endmill for holes and routing
[10:50:37] <Loetmichel> hmm
[10:50:37] <kfoltman> in fact, the reason the outline is so crappy is that it tried to treat the edges as tracks, and mill them on the outside and the inside, need to work on that part a bit
[10:50:43] <Loetmichel> i use a 0,1mm V-bit
[10:51:10] <kfoltman> I have some 0.1mm ones, but want to save them for the SMD boards
[10:51:18] <Loetmichel> ok, that makes sense
[10:51:32] <kfoltman> this is just a basic SPI splitter :)

[10:57:46] <kfoltman> I'm not even sure if using 0.3mm v-bits makes any economical sense, they're not significantly cheaper than 0.1mm, but perhaps less risk of them breaking or getting blunt quickly
[11:03:23] <Loetmichel> kfoltman: i use these: http://www.sorotec.de/shop/product_info.php/info/p179_vhm-fraesstichel-30-.html
[11:03:30] <Loetmichel> they come with "0" tip
[11:03:56] <kfoltman> how long do they last?
[11:03:58] <Loetmichel> you'll need a diamond file to make the vutting widht yourseld
[11:04:09] <Loetmichel> -d+f
[11:04:36] <Loetmichel> at least 5-10 100*160 pcbs if not soo much traces
[11:05:15] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=14507 <- made 5 of these with one bit and still no sign of wear
[11:05:20] <kfoltman> I used this exact one: http://www.ebay.ie/itm/281232558021
[11:06:05] <Loetmichel> 5 full 100*160mm pcbs, not five single boards
[11:06:21] <kfoltman> sounds quite durable

[11:06:39] <kfoltman> as in, doing G0 Z-30 instead of G0 Z30 ;)
[11:06:49] <Loetmichel> i like the "spiral" cut better than the halved types
[11:07:13] <kfoltman> what's the difference in results?
[11:07:27] <Loetmichel> rest assured: i even managed to weld a carbide mill bit shaft to the vice once
[11:07:46] <kfoltman> oops
[11:07:48] <Loetmichel> (g0 x-100 without g0z50 first)
[11:07:58] <Loetmichel> bumped sideways into the vice
[11:08:43] <kfoltman> can't 100% avoid these accidents
[11:08:50] <Loetmichel> ... steppers skipped, bit at 24krpm. got instant red, then white. as soon as i pressed the emergency the spindle stopped... and the bit was welded into the steel vice ;-)
[11:09:24] <kfoltman> you don't have this kind of accidents with proxxons :D
[11:09:38] <kfoltman> I mean the "instant red" part
[11:09:49] <Loetmichel> i was amazed that the 3mm carbide bit didnt break

[11:11:44] <kfoltman> mine was pretty much un-solderable before I used some IPA and a brush on it
[11:11:55] <kfoltman> no wetting at all

[16:01:04] <mani_> Hi
[16:01:44] <mani_> I compiled machinekit in ubuntu 13.14 with rt9 patch
[16:02:00] -!- raymondhim has quit [Quit: Nothing at all!]
[16:02:24] -!- raymondhim [raymondhim!raymondhim@jessica.totalsyssolutions.net] has joined #linuxcnc
[16:02:51] <mani_> everything is fine , latency-test is very low, event after an hour of watching youtube and copying file
[16:03:50] <mani_> but when runing stepconf in some irregular intervals all the IO freezez for 1 or two seconds and iotop and latency top are not much of a help!
[16:04:25] <mani_> by all IO I mean , keybaord and mouse , network and data streem to parallel port
[16:04:30] <mani_> any idea anyone?
[16:05:04] <mani_> * correction , ubuntu 14.04 with kernel 3.14
[16:05:15] -!- raymondhim has quit [Client Quit]
[16:05:49] <mani_> I can compile the same code on the installation of linuxcnc live cd and it works with no problem at all

[16:12:15] -!- acdha has quit [Client Quit]
[16:13:18] <mani_> hmmm, not much I guess , their code run with no problem with rtai, my guess is it has either something to do with my kernel or rtapi stuff in machinekit

[16:29:24] <pcw_home> another system
[16:30:17] <mani_> my freeze problem is on every IO , the parallel port data streem completely stops for a few moments
[16:30:55] <pcw_home> On the system with problems, nothing seems to make any difference
[16:31:34] <pcw_home> (but my I/O does not stop so probably not the same issue)

[16:31:40] <IchGuckLive> hi all B)
[16:31:43] <mani_> yeah
[16:32:14] <mani_> might be nmi or cache issue , don't know where to start
[16:32:29] <pcw_home> new MB?
[16:33:01] <IchGuckLive> did you turn the second cpu off by default
[16:33:53] <mani_> I checked with isolcpus=1 made no difference
[16:34:15] -!- theorbtwo has quit [Read error: No route to host]
[16:34:29] <pcw_home> in my experience is isolcpus is bad for Preemt-RT
[16:34:31] <IchGuckLive> so maybe a smi on the second cpu kills your port
[16:34:47] <pcw_home> no SMI on AMD
[16:35:07] <JT-Shop> mani_, is there some reason to want Ubuntu 14.04?
[16:35:23] <IchGuckLive> ok got to read the logs first then futher discussion O.O
[16:35:42] <mani_> don't care about 14.04 that much, just the new kernel ....
[16:35:46] <pcw_home> I _think_ master works with 14.04 now
[16:36:52] <mani_> second cpu doesn't cause any hard on the same hardware with live cd installation
[16:37:02] <JT-Shop> bleeding edge always stings a bit
[16:37:50] <mani_> yeah, been on it for 3 weeks now, Its becoming like my F35, too big to fail ; )
[16:37:54] <IchGuckLive> mani_: is it a mill or somthing else
[16:37:54] <pcw_home> try linuxcnc master

[16:40:46] <IchGuckLive> i see im gettng to old as linuxcnc did some major steps forward it is realy time to go for a old man like me
[16:40:55] <pcw_home> well he may not know that master supports preemt-rt now
[16:41:37] <pcw_home> it is more complicated with all the distribution and kernel options (and machinekit also)

[17:24:23] <Tom_itx> right
[17:24:43] <JT-Shop> which I like much better than Ubuntu >12
[17:25:17] <archivist> FinboySlick, I used a granite table many years ago at a previous job
[17:25:39] <FinboySlick> archivist: The price/accuracy ratio seems a little off.
[17:25:45] <IchGuckLive> FinboySlick: its best for mesuring parts
[17:26:09] <archivist> it seems cheap for the claimed accuracy
[17:26:12] <Tom_itx> yeah the only difference is the grade of them but most are plenty accurate enough
[17:26:28] <Tom_itx> size drives the price up too
[17:26:47] <FinboySlick> Shipping will likely be a bitch too.
[17:26:59] <archivist> go and collect
[17:27:10] <CaptHindsight> FinboySlick: I use them since they are local for me
[17:27:23] <CaptHindsight> I use the smaller ones for machine bases
[17:27:38] <Tom_itx> we had a large one in the shop
[17:27:50] <Tom_itx> probably 3 x 6 x 6"
[17:28:20] <Tom_itx> half of it usually got used to lean against looking at blueprints
[17:29:36] <archivist> if you are less fussy and can measure, try a granite floor tile, I have looked at the reflected light in the shops and they seem more flat than I would have expected
[17:29:44] <CaptHindsight> I also have surface plates from Enco, I;m not sure if it was a typo or web store mistake but their 24 x 36 surface plates with the table were lower cost than just the surface plate alone
[17:30:40] <Tom_itx> this was used for most of the part checking: http://clearwateren.com/quality-assurance.php
[17:31:13] <archivist> background is a granite tile http://www.collection.archivist.info/archive/DJCPD/PD/2014/2014_01_19_Cyprus_gears/IMG_1733.JPG
[17:32:14] <FinboySlick> CaptHindsight: I'll be sure to check for both then.
[17:32:38] tronwzrd is now known as tronwizard
[17:33:06] <CaptHindsight> http://www.use-enco.com/CGI/INPDFF?PMPAGE=363&PMITEM=640-1960
[17:33:34] <Tom_itx> really just depends on the accuracy required
[17:34:31] <CaptHindsight> $190.98 for just the stand, $193.04 for the table with the plate :)
[17:35:25] <PetefromTn_> afternoon guys.
[17:35:32] <PetefromTn_> and gals LOL
[17:35:35] <Tom_itx> build a stand
[17:36:22] <CaptHindsight> so for $3 you get the plate with the stand
[17:36:31] <CaptHindsight> $3 more
[17:36:34] <Tom_itx> heh
[17:36:49] <Tom_itx> call and try that logic on them
[17:36:51] <CaptHindsight> the plate is grade B
[17:36:56] <LeelooMinai> I guess they really want to get rid of those stands:)
[17:37:26] <CaptHindsight> the stands are just grey powder coated angle iron
[17:37:46] <PetefromTn_> nice I love my granite surface plate.
[17:38:03] <Tom_itx> you can build a stand for probably $20 in scrap material or less
[17:38:22] <PetefromTn_> I did not buy or build a stand but repurposed an old computer server rack into it LOL
[17:38:22] <CaptHindsight> lower than the shipping cost
[17:38:26] -!- toner has quit [Ping timeout: 250 seconds]
[17:38:27] <LeelooMinai> I always wanted one, but they are, kind of unshippable - heavy like a samll elephant.
[17:38:35] <Tom_itx> then ship it to JT-Shop for powdercoat :)
[17:39:01] <FinboySlick> LeelooMinai: I have a feeling that'll be my situation too.
[17:39:23] <Tom_itx> check a local craigslist
[17:39:53] <archivist> I got an ex army surplus cast iron plate, was a happy bunny when I got it

[17:40:46] <Tom_itx> you should get out more often
[17:41:08] <CaptHindsight> FinboySlick: how large an area do you need?
[17:41:33] <zeeshan> LeelooMinai: you suck at finding stuff
[17:41:39] <Tom_itx> even a nice sized piec of 1/2" glass would be better than nothing

[17:41:50] <zeeshan> go get one
[17:41:53] <zeeshan> its 38$ locally
[17:41:59] <FinboySlick> CaptHindsight: 24x36 is what I'm looking at. It don't think I'd ever need to check anything larger than that.

[17:45:51] <zeeshan> mississauga is closer
[17:46:14] <PetefromTn_> you could probably strap it to your bike handlebars LOL
[17:46:19] <zeeshan> hah
[17:46:43] <LeelooMinai> Right, and If I crashed into a car, that would be first time when biker killed a car driver.
[17:47:17] <PetefromTn_> since when do bikers care about car drivers? hehe
[17:47:47] <PetefromTn_> I could probably tote my granite plate on my recumbent bike would not want to go too far with it
[17:49:29] <PetefromTn_> before I got my granite plate I was using a ground chunk of granite I got from a local monument shop. they gave it to me for free as it was a goof up apparently. when I asked them how flat they thought it might be they said it would be pretty damn flat due to their polishing processes.
[17:49:40] <PetefromTn_> It sure was prettier than my granite plate LOL.

[17:53:12] <PetefromTn_> Yeah basic layout using the height gauge scribing and measuring flatness of parts I was planning to do offline measurement of my toolholders but I have yet to machine the custom mount for it.
[17:53:18] <archivist> it is a must have that usually sits doing nothing
[17:53:50] <FinboySlick> archivist: Same goes for a lot of other tools.
[17:53:50] <PetefromTn_> I try to keep a clean towel on it when not being used but lately I find myself putting my machines keyboard on top of it while I work. Not a good practice.
[17:54:03] <Tom_itx> test bench for first articles...
[17:54:22] <PetefromTn_> sure some tools get seldom used but they have their purpose that none of the other tools can do when you need it.
[17:54:23] <archivist> FinboySlick, there is always the milling machine table
[17:54:48] <FinboySlick> archivist: You're funny.
[17:55:14] <JT-Shop> yea, like my surface grinder... I rarely use it but when I need it nothing else will do
[17:55:23] <archivist> well some machines are flat, how is yours coming on
[17:55:31] <PetefromTn_> Damn I would love to have a nice small manual surface grinder.
[17:55:55] <FinboySlick> archivist: Still no room to actually work on it. It'll probably have to wait another year before I can actually get started on it.
[17:56:14] <PetefromTn_> when I worked in the shop over there they used them for all sorts of stuff. Most notably to modify cutter shanks for clearances and other things.

[21:46:12] <Benjamin23> ha

[21:48:30] <Benjamin23> coreldraw? wow, I haven't heard that name in a long time
[21:49:05] <Benjamin23> did you build you CNC machine, buy parts/kit, or buy one outright?
[21:49:09] <jthornton> we normally just ask the question
[21:49:34] <jthornton> 1 and 3
[21:49:59] <Loetmichel> build all of them
[21:50:10] <Loetmichel> exept the one at the company
[21:50:39] <jthornton> I use gedit or OneCNC
[21:51:00] <jthornton> depends on the machine, my CHNC I use ngcgui for 95% of the ops
[21:51:26] <Loetmichel> ... occasionaly i use notepad
[21:51:40] <jthornton> oh and sheetcam on my plasma usually
[21:51:59] <Benjamin23> interesting. I see there are many options, and resourcefulness is key if someone is going to build one
[21:52:35] <jthornton> depends on the type of machine your after if you can cheaply build one that works or not
[21:52:45] <Benjamin23> I've been looking for free cad files to build a CNC from another CNC cutter, or 3D printer, or both, but not having too much luck
[21:53:47] <jthornton> what are you building a router, a glue gun???
[21:53:58] <Benjamin23> I'd like to begin with a simple dremel CNC cutter, and then move on
[21:54:36] <Loetmichel> Benjamin23: do yourself a favor: shed that demel
[21:54:45] <jthornton> Loetmichel, has some very nice routers that he built
[21:54:59] <Loetmichel> and use at LEAST a proxxon tool
[21:55:00] <jthornton> as mentioned a dremel is not a CNC spindle
[21:55:09] <Loetmichel> (ib/e to be precise)
[21:55:28] <Benjamin23> I'm sure he does, and would like a very pretty gold coin for them
[21:55:28] <Loetmichel> the dremels are notoriously weak
[21:55:32] -!- jrcharney has quit [Quit: leaving]
[21:55:50] <Loetmichel> no
[21:55:58] <jthornton> and the spindle is mounted in rubber I think
[21:56:17] <Benjamin23> got that part about the dremels. Very fast, and very noisy for the dremels.
[21:56:19] <Loetmichel> i aim at desinging a kit that can be sold for less than 1000 eur... and do that since 2009 ;-)
[21:56:24] <Loetmichel> i dont sell anything now
[21:56:31] <Benjamin23> that's too bad
[21:56:36] <Loetmichel> he meant to look at my pics and get ideas
[21:56:42] <Benjamin23> it's also to bad 1000EUR is about 1600USD
[21:56:43] <jthornton> yep
[21:57:00] <Benjamin23> well, send me a link if you don't mind, Loet

[22:40:37] <Loetmichel> yeah, thats 2mm fr4

[22:41:31] <Loetmichel> its light and extremely rigid
[22:41:38] <Loetmichel> but a bit on the expensive side
[22:41:45] <tjtr33> what do you cut with? fr eats up most tooling
[22:42:17] <tjtr33> also highly insulative ( i make edm fixtures with it ;)
[22:42:35] <Loetmichel> tungsten carbide tools
[22:42:38] <Loetmichel> what else?
[22:42:39] <tjtr33> carbide even dulls quickly ( for me )
[22:42:45] <Loetmichel> it does
[22:42:57] <Loetmichel> i have some TC tools taht are diamond dus coated
[22:43:02] <Loetmichel> that lasts longer
[22:43:25] <tjtr33> TC = WoCu?
[22:43:39] <tjtr33> no, forget that
[22:43:40] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=364 <- second from the right
[22:43:48] <Loetmichel> tungsten carbide
[22:44:20] <tjtr33> thx!
[22:44:29] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=2967 <- Tungsten carbide with diamond coating
[22:45:10] <Loetmichel> http://www.sorotec.de/shop/index.php/cat/c56_Spiral-Toothed-Coated-Spiral-Toothed-Coated.html <- bought them there
[22:47:03] <tjtr33> bookmarked, thx! at 10$/1mm dia, it would cut well & last ( upcut, hi-helix... nice )
[22:49:11] <Loetmichel> i usually got about 100m slot from an uncoated one, and boult 500m from a coated one
[22:49:25] <Loetmichel> s/boult/about
[22:56:07] <Benjamin23> how long do the tungsten carbide bits last
[22:57:07] <Loetmichel> Benjamin23: depends on the material
[22:57:32] <Loetmichel> like i said above: about 100 meters slot in 3mm fr4 (pcb material)
[22:57:44] <Loetmichel> about forever in plastics
[22:57:52] <Benjamin23> interesting
[22:58:21] <Benjamin23> I was concerned about that. But for the amount of material for an inexpensive part compared to a CO2 laser tube
[22:58:22] <Loetmichel> tjtr33: the coated bits have interesting capabilites.
[22:58:51] <Loetmichel> if you have a spindle capable of 80krpm you can shove a 2mm bit thru fr4 with F4000
[22:59:11] <Loetmichel> and thats from the manufactureres datasheet
[22:59:57] <Loetmichel> and 6mm deep into the material...
[23:00:06] <Loetmichel> i had problems getting rid of the dust...
[23:00:17] <Loetmichel> the vacuum hadnt enough volume ;-)
[23:02:01] <tjtr33> Loetmichel, sorry was away, I only have 30K, but would consider new spindle if i get enuf need for cutting FRP (4M/min! )
[23:02:05] <Benjamin23> 80k rpm?
[23:02:41] <tjtr33> yeah its router stuff, past most mill speeds
[23:03:13] <Benjamin23> that is fast. Loet: what program do you use to design PCBs?
[23:03:24] <Loetmichel> target 3001
[23:03:35] <Loetmichel> and it isnt fast
[23:03:54] <Loetmichel> professional pcb routers have 120kRPM spindles
[23:04:14] <Loetmichel> they dont drill, they punch
[23:04:16] <Loetmichel> :-)
[23:04:26] <Loetmichel> "time is money"
[23:04:37] <Loetmichel> did that myself on carbon
[23:04:56] <Loetmichel> https://www.youtube.com/watch?v=mj8sGEf8Wf8
[23:05:06] <Loetmichel> but wiht a 3mm drill bit and only 24krpm
[23:05:07] <Benjamin23> is PCB design what you do for a living
[23:05:25] <SpeedEvil> I've idly wondered about the 500K RPM experimental air-bearing spindles
[23:05:33] -!- swingley has quit [Ping timeout: 260 seconds]
[23:05:37] <Loetmichel> no, i shield it tech against eavesdropping
[23:07:46] <tjtr33> i thought you meant carbon like in SenkErodieren https://www.youtube.com/watch?v=6VmDRpeh9sI
[23:08:48] <Benjamin23> alright. Can laser of some type be used to etch PCBs?
[23:10:10] <SpeedEvil> Benjamin23: yes - but generally not well
[23:10:22] <SpeedEvil> Unless it's an expensive laser
[23:10:29] <SpeedEvil> copper vapour lasers can cut copper well
[23:11:21] <Benjamin23> interesting
[23:12:44] <SpeedEvil> But a 20W CVL is not very inexpensive
[23:12:52] <Loetmichel> Benjamin23; unlikely
[23:13:02] <Loetmichel> because copper reflects very well.
[23:13:08] <Loetmichel> and disperses heat
[23:13:23] <Loetmichel> the base material( fr4) does the opposite
[23:13:27] <SpeedEvil> Copper is actually used as a cavity mirror for FR4
[23:13:34] <SpeedEvil> err
[23:13:36] <SpeedEvil> For CO2
[23:13:47] <Loetmichel> SpeedEvil: exactly
[23:13:53] <SpeedEvil> Bare polished copper works just fine for that
[23:13:55] <Loetmichel> you CAN cut copper with co2
[23:14:12] <Loetmichel> but you need LOTS of power and a means of blackening it
[23:14:16] <SpeedEvil> For blue, or green lasers it absorbs enough to be cut - thouh it is hard to cut
[23:14:23] <Loetmichel> and the base material will be cut as well
[23:15:31] <Benjamin23> sounds like a simple router spindle is what I will use
[23:15:34] <Loetmichel> SpeedEvil: the problem isnt cutting the copper
[23:15:49] <Loetmichel> bit NOT removing the base material in the process ;-)
[23:16:31] <Loetmichel> Benjamin23: if you have the money: get a chinese 800W watercooled 3 phase ac spindle with vfd
[23:16:58] <Benjamin23> nope. Going to have to real creative and resourceful
[23:17:06] <Loetmichel> they are not sooo expensive and a complete diffrent league from routers... not to mentoin dremel/proxxon tools
[23:17:31] <Loetmichel> Benjamin23: they are not that expensive
[23:17:42] <Loetmichel> and spare you from a LOT of headache
[23:17:46] <Benjamin23> does the speed have anything to do with the amount of material cut, or is it torque?
[23:17:53] <Loetmichel> diameter
[23:18:07] <Loetmichel> as smaller the bit, as higher the rpm
[23:18:35] <Loetmichel> if you want to make pcbs: buy such a cnc6040
[23:18:45] <Loetmichel> it doesnt get better for that money
[23:18:51] <Benjamin23> for the purpose of cutting faster, not necessarily forcing the bit, but just cutting material faster in order to enable moving along at after rate?
[23:19:15] <Loetmichel> https://www.youtube.com/watch?v=jMXxjT4nNxg
[23:19:58] <Loetmichel> Benjamin23: the linear speed a cutting edge has to do to cut efficient has to stay constant
[23:20:12] <Loetmichel> so if the tool gets smaller the RPM must rise

[23:21:48] <Benjamin23> where does torque come in? Or is a relation between speed and torqe, ie, the spindle does not slow down when cutting something at a desired cut rate?
[23:22:46] <Loetmichel> the latter
[23:23:18] <Loetmichel> in my experience the 800W chinses spindles have way enough torqe
[23:23:43] <Loetmichel> the dremels at 100W havent, though

[23:27:27] <jdh> my chinese 1.5kw seems pretty spiffy. And quiet
[23:29:15] <Loetmichel> right

[23:35:09] <tjtr33> is a 7i33's ENA really an enable of PWM (enables the Aout created from PWM and DIR)? and is not an amplifier enable?
[23:35:59] -!- asdfasd has quit [Ping timeout: 264 seconds]
[23:36:05] <pcw_home> its just an active high ENA out signal
[23:36:40] <pcw_home> (inverse of the active low enables on the FPGA side)

[23:37:50] <tjtr33> if a servo drive has an ENABLE pin, is this what gets connected? ( i'd guess not )
[23:38:39] <pcw_home> no, unless it can take 5V CMOS levels
[23:39:37] <pcw_home> new daughter cards (7i48, 7I77 etc) have OPTOS for that function
[23:40:02] <tjtr33> cool, but i already have 7i33 and 7i37s
[23:40:37] <Benjamin23> ok, say I get a CNC6040 or the 3040. Does linuxCNC work with it "out of the box" or is there some other crazyness that needs to be done to make it work?
[23:41:08] <jdh> I plugged mine in and it worked.
[23:41:30] <tjtr33> thats no fun
[23:41:40] <jdh> actually, it was what I was hoping for.
[23:41:51] <Benjamin23> and what it the difference between the L, C, T models?
[23:41:51] <pcw_home> you can usually use a 7I37 output for drive enable (unless its one of the odd ground to disable ones)
[23:42:05] <jdh> having to remember to turn the spindle on is a pain though. Need to fix that.

[23:43:07] <tjtr33> pcw_home, i think it _is_ what you describe, but i'd run a relay dry contact NC to short it to gnd, and on command, open the relay & un-inhibit the drive
[23:43:34] <tjtr33> SMAC LAA-5
[23:44:15] <pcw_home> yeah some old drives are like that which seems weird (a broken wire enables the drive)
[23:44:33] <tjtr33> haha thats right!
[23:45:35] <tjtr33> internal 9V pull up to 1k res to /inhibit. and another pin /inhibit-return internall cnxd to gnd
[23:45:39] <pcw_home> we are considering using form B SSRs as an option on some cards (you can get photo MOSFET form B (NC) SSRs)
[23:45:41] <pcw_home> same pinout and size as the OPTOS we use
[23:46:08] <pcw_home> a bit more expensive but not terrible
[23:46:32] <pcw_home> most people just use a NC relay
[23:47:00] <pcw_home> some drives have solder options to reverse the logic
