[00:07:17] <NickParker> Someday, I will truly learn to RTFM.
[00:07:43] <NickParker> I've been putting off my mill conversion for a good 2 weeks because I thought the optos on it didn't work on 5v
[00:07:55] <NickParker> Didn't realize 6i25 outputs are 3.3v...
[00:08:19] <NickParker> converters are in the mail now, it should be all up and running in a few days.
[00:08:34] <XXCoder1> nice
[00:11:27] <NickParker> Poking the optos with actual 5v and feeling the stage thump along a step was pretty satisfying.
[00:11:44] <NickParker> I've done that with little steppers before, but 18 lbs is a new personal record
[01:24:51] <Jymmm> skunkworks_: Is there a more generic term for it by chance?
[01:25:03] <Jymmm> skunkworks_: thanks btw
[02:05:26] <Deejay> moin
[02:57:32] <eneuro> Hello, Could you help me choose vismach simulation http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Vismach for this 3 axis machine (it is like reverse lathe, while tools are rotated and move around mounted workpiece) http://www.linuxcnc.org/index.php/english/forum/49-basic-configuration/27846-cartesian-g-code-to-cylindrical-machine-coordinate?
[03:10:01] <archivist> probably need to write kins for that machine
[03:11:39] <archivist> but a 5 axis mill can also do the same as what you are doing
[03:12:08] <eneuro> but where to do it-do I need change vismach.py ?
[03:14:34] <archivist> your machine is something like XCZ
[03:15:10] <archivist> C being the upward rotary around Z
[03:16:14] <eneuro> but why XCZ and not CYZ?
[03:16:23] <archivist> so it is a transform between XY (cartesian) to XC (vector) via some trig
[03:17:08] <archivist> X or Y not not a lot of difference
[03:18:05] <archivist> here one either works to a convention or just choose something that works for you
[03:18:45] <archivist> the order of YC or CY is the order it is applied in the model
[03:20:22] <eneuro> so it looks like I could send Cangle in LPT X, Yradius as LPT Y, and Z without any conversion in LPT Z..
[03:21:14] <archivist> LPT knows nothing, you can drive any axis as you want
[03:22:35] <eneuro> only reason for this is in my convention X is marked red, Y green, Z blue and machine parts colour is the same...
[03:23:59] <eneuro> I found that vismach is run using standard Hal tool $ halrun -> loadusr 5axisgui . So I need to create hal configuration for vismach?
[03:26:42] <archivist> yes and also the hardware images to match your machine
[03:27:12] <eneuro> I will try to follow this vismach tutorial with 5axisgui example and try to setup my machine...
[03:28:00] <eneuro> but which hardware images? I can make STL files easy in Blender or even generate them in software using my STL library?
[03:28:01] <archivist> so far I have been too lazy to do my 5 axis :)
[03:28:50] <archivist> eneuro, if you look in the examples they are drawn direct in the python
[03:30:17] <archivist> long time since I looked at that code
[03:30:43] <eneuro> yep, but there is also section ".stl or .obj import" but without STL example I guess: part = AsciiSTL(filename="path/to/OBJ_file.obj") maybe could work with my STL?
[03:31:55] <eneuro> why not to do it this way desrcibed in this doc "Use a CAD and export .obj or .stl files for each axis consisting the geometry. The files can be produced using [FreeCAD]: Model the solid for each axis, create a mesh and [export] it as .obj or .stl. " ?
[03:34:01] <eneuro> but ok it does not matter, while I could generate... python code if wanted for this machine if I know how to setup this thing and connect to LinuxCNC...
[03:34:27] <archivist> yes that was not not around when I looked
[03:36:05] <archivist> and I also move my axes around on the machine to do different work so vismach would need an update per job so I stopped looking at it
[03:36:10] <eneuro> I'm not sure how eg. Axis from LinuxCNC will change my vismach machine state? I guess I need to run hal, load my machine or do it something else?
[03:37:03] <eneuro> I'd like to have Axis running and... in another terminal run this vismach machine script?
[03:37:45] <archivist> the hal connections are the key there, they connect vismach to the machine
[03:38:07] <archivist> yes you run the script separately
[03:38:26] <eneuro> nice ;)
[03:38:39] <archivist> then it just works :)
[03:40:39] <eneuro> so, now I will have to try to write this code to crack hal to make this transformation from cartesian xyz, to lets say CYZ, run linuxcnc with Axis and in manual MDI try to move my virtual machine I guess..
[03:43:30] <eneuro> I wonder if there is C/C++ interface to LinuxCNC hal? Then I could try to write my own OpenGL application with my machine simulation I guess?
[03:46:46] <archivist> why reinvent when vismach is already there, but yes anything is possible
[03:47:23] <archivist> kins is the part where you need to think
[03:48:50] <archivist> why are you making the machine this way? is it for large(round) objects
[03:49:03] <eneuro> I prefere C/C++/Java but I can try do it in other language... kins you mean kinematics or this is something special to vismach something else?
[03:49:16] <archivist> kinematics
[03:50:26] <eneuro> but kins in vismach or general using Hal and configure it with LinuxCNC?
[03:51:13] <archivist> kinematics in linuxcnc, vismach reads what the machine is doing
[03:52:22] <eneuro> yep, so I think I need a little break before start hacking linuxCNC HAL :D
[03:57:57] <eneuro> I've found that someones were trying to make LinuxCNC running as diskless machines using network ony and found some manual but to EMC2 http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Debian_Etch_Server_And_Diskless_LinuxCNC_Thin_Clients anyone got it working with latest LinuxCNC 2.5.4?
[04:03:43] <eneuro> "This page describes how to prepare a system with a Debian Etch server and many diskless EMC2 thin clients" why only Debian Etch-why not to simply install latest LinuxCNC with updates and configure it with NFS/SSH/TFTP server?
[04:03:59] <eneuro> on nother machine?
[04:04:04] <eneuro> another
[04:22:13] <eneuro> I was able to install nfs-kernel-server with latest LinuxCNC 2.5.4 updated-lets see if I will be able to setup it his way, the diskless clients can run LinuxCNC without a local harddisk, just inserting network cable? ;)
[07:49:22] <zq_> man
[07:49:28] <zq_> the build system is so broken it ain't even funny
[07:51:47] <archivist> What OS
[07:57:57] <zq_> x86_64-linux-gnu
[07:58:04] <zq_> not that it matters
[07:58:35] <zq_> i rolled back to 2.2.8 when things were less broken
[08:05:10] <archivist> you should be on a 32 bit system with 2.2 that is so old
[08:43:58] <lair82> Is it supposed to be allowable to perform another MDI function before the first function is finished? Reason I ask is, I noticed the other day on one of our turning centers that I performed a tool change, and before it had finished the first change, I entered another change and my tool turret took off spinning. I did this a few more times and it would do it everytime.
[08:45:07] <lair82> Essentially another tool change request was allowed before the first tool change had been acknowledged as finished.
[08:48:37] <_methods> interesting
[08:48:57] <_methods> did it complete teh 2nd tool change command?
[08:49:23] <archivist> sounds a bit like a bug
[08:50:53] <_methods> what happens if you put
[08:50:58] <_methods> T1M6:
[08:51:04] <_methods> T2M6;
[08:51:42] <_methods> does it do 2 tool changes? or just do the last tool change?
[09:27:29] <PetefromTn_> Mmmmoornin' folks.
[09:43:11] <pcw_home> NickParker (shoud you read this later): you can drive 5V OPTOs from the 6I25
[09:45:11] <pcw_home> you connect the OPTO + to 5V the OPTO- to FPGA GPIO pin and set the GPIO pin attributes is-output and is-opendrain
[09:51:40] <NickParker|2> pcw_home: the OPTO - on my drivers are tied together in pairs unfortunately.
[09:51:58] <NickParker|2> It's no big deal, I have converters coming to bump the 3.3v up to 5v
[09:52:01] <CaptHindsight> PCW: http://www.micrel.com/index.php/en/products/lan-solutions/ieee-1588.html do you have drivers for these? or for the standard 10/100 controllers
[10:02:57] <lair82> it will not finish the second tool change, the tool turret will just keep spinning aimlessly until a counter that I programmed in classicladder stops rotation and sends a fault out that the turret is faulted.
[10:06:11] <lair82> My turret is completely controlled through ladder, after it is finished with its change and retracts to the clamped position, i have a 1 second delay until it pulses the motion.tool-changed pin high, just for safety reasons I have that 1 second delay.
[10:08:22] <lair82> This is on a Cincinnati Milacron turning center, machine weight 38,500lbs with a 7 tool disc turret that weighs in around 2500lbs with all tooling loaded, thats why I have lots of safe guards built into my ladder logic.
[10:16:21] <_methods> except the safeguard that keeps it from doing 2 consecutive tool changes lol
[10:48:18] <pcw_home> CaptHindsight: we are using the KSZ8851-16MQL
[10:50:26] <pcw_home> micrel's IEEE1588 MACs are too expensive for us (we would use the much cheaper STM32F4 uproc if IEEE1588 was a requirement)
[10:54:34] <CaptHindsight> Intel lacks the GPU's for me to be interested (among years of bad history) in trying to use them
[10:54:58] <CaptHindsight> ethernet is on all the mini-itx boards
[10:56:23] <CaptHindsight> I keep waiting for someone to beat me to it but all I need is a small form factor Linuxcnc controller at a realistic price
[10:57:17] <SpeedEvil> What do you mean by 'small form factor' - and why are intel GPUs bad?
[10:57:23] <SpeedEvil> My i3's one is fine
[10:57:53] <CaptHindsight> 10-12" tablet sized controller
[10:58:01] <pcw_home> The J1800s are fine also (much better than the Atoms)
[10:58:24] <pcw_home> also lower power
[10:58:30] <CaptHindsight> no coreboot support unless Google decides to put it into a product
[10:58:34] <SpeedEvil> ah
[10:59:00] <pcw_home> coreboot for baytrail is supposed to be available
[10:59:09] <CaptHindsight> i just stopped developing with Intel ~10 years ago unless paid insanely well
[11:00:16] <pcw_home> http://www.phoronix.com/scan.php?page=news_item&px=MTU4OTU
[11:00:37] <CaptHindsight> unless the coreboot port is for the exact mainboard and exact rev you need docs
[11:01:30] <CaptHindsight> plus now we get HD8xxx graphics in the <10W AMD APU's
[11:02:04] <pcw_home> but a slow CPU
[11:03:07] <CaptHindsight> so Intel is out
[11:04:05] <SpeedEvil> I note that my I3 (desktop) is drawing about 18W, now, and I think I can get that to 12.
[11:04:09] <SpeedEvil> In use.
[11:04:23] <pcw_home> Just sayin AMD has nothing in the same ballpark as the baytrails
[11:04:40] <CaptHindsight> not a problem
[11:04:56] <SpeedEvil> On a more silly point - I wonder if a generic intel tablet with thunderbolt can have a thunderbolt->pcie bridge
[11:04:57] <CaptHindsight> Intel just won't work out
[11:06:06] <CaptHindsight> A10's and A20's have enough CPU, and of the AMD APU's have been fast enough as well
[11:08:45] <tjtr33> i got the BBB running linuxcnc last night, and now what to do with this QBboard? ( hint hint nudge nudge )
[11:09:17] <tjtr33> 50" lcd tv was only hdmi i had :)
[11:09:40] <CaptHindsight> all the announcements for Linux support on the Allwinners was premature, all the images are magical mystery distro's
[11:10:07] <tjtr33> awww
[11:10:30] <CaptHindsight> is the display larger than the machine? run simulations at 2X the size of actual
[11:10:47] <tjtr33> 2x simulation is almost for real?
[11:11:30] <CaptHindsight> whats the QB board?
[11:11:43] <tjtr33> CubieBoard ( lazy typist)
[11:12:16] <CaptHindsight> the debian image works with linuxcnc....
[11:12:38] <CaptHindsight> but how it all works and supporting it is a mystery still
[11:13:16] <tjtr33> then i can just try the debian 7.4 sd card
[11:13:35] <tjtr33> ran ok on BBB
[11:13:42] <CaptHindsight> it takes a day or two of fiddling to get linuxcnc to run
[11:13:54] <tjtr33> argh!
[11:14:07] <CaptHindsight> mystery tool chain
[11:14:49] <CaptHindsight> 15 people all race to first post "I have a login prompt" then don't show how they built it
[11:15:14] <cradek> then "who cares just copy my disk image"
[11:15:26] <cradek> that's a disturbing trend
[11:15:29] <CaptHindsight> but that doesn't stop 87 companies from making products with it that almost work
[11:15:54] <CaptHindsight> that's how it's been getting
[11:17:06] <tjtr33> yeah, thats what happened for me. sorry the howto for machinekit is pretty much missing. follow the debian howtos and get real lost. and silly me, i dont know if i can recreate the steps that finally worked.
[11:17:27] <tjtr33> but will note now while it's "fresh" haha
[11:17:51] <tjtr33> imagewriter does NOT work . xzcat does NOT work, dd does
[11:18:16] <CaptHindsight> thats how the ISO's are for the allwinner stuff
[11:18:33] <tjtr33> the startup screen has menus on the overscan so, you have to enable the rt click menus manually
[11:18:34] <CaptHindsight> you see tons of installed packages but many don't work
[11:18:50] <tjtr33> then you can get a terminal, then you can run linuxcnc
[11:19:15] <CaptHindsight> reminds me of all the early Chinese tablets with Linux
[11:19:26] <tjtr33> no idea whats on menu ( if any) it outta my view
[11:20:03] <tjtr33> those were cool I had one with handwrtining input, practiced Big5 charcters
[11:20:11] <CaptHindsight> or you could load an app that wouldn't fit on the desktop and they didn't enable scrolling
[11:20:46] <CaptHindsight> so the checkbox to save screen resize would be below the taskbar :)
[11:21:02] <tjtr33> haha we had that with linuxcnc a few times. 800x600 was new
[11:21:37] <tjtr33> not linuxcnc's fault, more gnome or whatever we used in the day
[11:21:57] <CaptHindsight> yeah or enable panning
[11:22:13] <CaptHindsight> we had panning on the Mac512's
[11:22:45] <tjtr33> oh bigger virtual screen than phy screen yeah
[11:22:55] <CaptHindsight> it was like working by looking through a big keyhole but it worked
[11:23:44] <eneuro> did you tried this diskless LinuxCNC boot from this page? http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Debian_Etch_Server_And_Diskless_LinuxCNC_Thin_Clients I have .TFTP error 1 (File not found)...
[11:23:53] <CaptHindsight> and that was 30 years ago
[11:25:18] <eneuro> after powering diskless PC ... dhcp client sets correct IP...
[11:25:37] <tjtr33> i'd like this solution for schematics pan zoom scale problems ( data way larger than screen ) http://lmnts.lmnarchitects.com/interaction/grasshopper-canvas-meet-kinect/
[11:25:56] <tjtr33> sorry eneuro no experience
[11:31:00] <CaptHindsight> pcw_home: 2khz stepping over ethernet, is that shared between the multiple motors or can you have 4-5 steppers all at 2khz?
[11:37:30] <eneuro> I was so close and had boot pxelinux screen to boot LinuxCNC from network and changed something and no way... ok it is time to break ;)
[11:38:33] <CaptHindsight> http://www.newegg.com/Product/Product.aspx?Item=N82E16824009610 20" touchpanels for $160
[11:43:39] <jdh> if my mill panel as anywhere near completion, I'd think about buying one
[11:45:17] <IchGuckLive> hi all B)
[11:48:45] <pcw_home> CaptHindsight: 2 KHz servo loop MHz step rates...
[11:48:53] <IchGuckLive> today bearly no minute without a post her in the daylogging
[11:52:11] <CaptHindsight> pcw_home: is that point to point with no switch between nic and nic?
[11:52:51] <pcw_home> Yes point to point (a switch wont hurt much though)
[11:53:10] <pcw_home> (other traffic _will_ hurt)
[11:53:46] <pcw_home> because its still realtime
[11:53:59] <CaptHindsight> so multiple nics on mainboard if you want to expand or have cnc on one nic and internet on another
[11:55:07] <pcw_home> Yes (or use usb/enet for general net usage)
[11:55:34] <CaptHindsight> skunkworks mentioned a laptop that he was using with linuxcnc, I never heard what he had connected and to what port
[11:56:21] <pcw_home> (thats what I have on my test system currently, MB Ethernet for RT USB --> Ethernet for inet)
[11:56:52] <CaptHindsight> a laptop with good latency numbers could use the nic for cnc and USB-ethernet dongle for internet
[11:57:02] <pcw_home> sure
[11:57:36] <pcw_home> or WIFI for inet
[11:57:39] <CaptHindsight> expresscard slots are disappearing form laptops
[11:59:13] <pcw_home> Yeah
[12:00:02] <pcw_home> although even no slot mini itx MBs have MiniPCIE
[12:00:27] <pcw_home> (Just happen to have an adapter...)
[12:03:21] <CaptHindsight> SPI driver still a mess with Allwinner as well
[12:05:00] <CaptHindsight> maybe I'll visit Microcenter, Tiger Direct etc today with Linuxcnc on a flash drive
[12:06:19] <CaptHindsight> after testing laptops 1-2 the salespeople start getting nosy, think you'r hacking or leaving virus or malware on them :)
[12:08:16] <tjtr33> at tiger find the geek saleskid who interested , maybe willing to find a new way to sell some units once qualified
[12:08:33] <tjtr33> on a weekday they got time
[12:08:34] <CaptHindsight> yeah, had him a drive to use
[12:09:34] <tjtr33> go naperville, not schaumburg
[12:09:36] <CaptHindsight> http://www.ebay.com/itm/like/181127388375 LPT to ExpressCard Express Card $12.88
[12:11:09] <pcw_home> spi driver should be less than 20 or so lines of code
[12:11:10] <CaptHindsight> Vernon Hills as well
[12:11:31] <CaptHindsight> for the host?
[12:11:41] <pcw_home> yes
[12:11:43] <CaptHindsight> kernel driver
[12:11:51] <CaptHindsight> no docs
[12:12:03] <pcw_home> kernel driver is a mistake
[12:13:00] <pcw_home> just low level hardware access
[12:13:10] <pcw_home> ban all other access
[12:13:14] <CaptHindsight> http://lkml.org/lkml/2014/2/22/178 oh it's up
[12:13:39] <_methods> http://www.phytec.com/products/single-board-computers/
[12:13:57] <pcw_home> not useful for RT
[12:14:15] <_methods> ah
[12:15:25] <Loetmichel> pcw_home: that depends
[12:15:53] <Loetmichel> Pcnc-DOS had run gread on a 406-100
[12:15:55] <Loetmichel> great
[12:16:30] <Loetmichel> so the cpu should be fast enough. as long as it hasnt to copw eith multiuser/multitasking OSes ;-)
[12:16:32] <IchGuckLive> hi Loetmichel thunder overhad at your hometown
[12:16:52] <Loetmichel> <- suny and hot evening, dont know hat you mean
[12:17:08] <Loetmichel> +n
[12:17:34] <pcw_home> the "not useful for RT" was in response to a SPI kernel driver
[12:18:30] <_methods> http://newsoffice.mit.edu/2014/algorithms-produce-patterns-that-could-hide-public-eyesores-0521#.U30AvlAij9U.twitter
[12:18:37] <_methods> kinda cool
[12:18:48] <Loetmichel> pcw_home: oh sorry
[12:19:00] <Loetmichel> i thought you meant that small arm computer
[12:20:24] <pcw_home> The Vybrids are interesting kind of like a Sitara/PRU done right (with RT processor a full ARM with FP)
[12:21:37] <CaptHindsight> with the SPI kernel driver we now know the registers for the controller
[12:22:15] <pcw_home> the A10 manual has all the registers
[12:23:01] <IchGuckLive> tmart pd20 at 80USD has a A10 inside
[12:23:06] <pcw_home> and a fairly good description (I suspect the SPI is standard ARM boilerplate)
[12:29:13] <CaptHindsight> I forget what the hangup was then with SPI, yeah the resisters are in the User Manual
[12:31:31] <eneuro> finaly I've got ubuntu splash screen while booting regular pc via network from other ubuntu server in VirtualBox (latest LinuxCNC 2.5.4 iso installed updated with tricks from http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Debian_Etch_Server_And_Diskless_LinuxCNC_Thin_Clients#Preparing_a_sample_client_system :) Need only provide LinuxCNC root filesytem while do not exported full yet ;)
[12:33:54] <CaptHindsight> http://www.ebay.com/itm/Parallel-Port-DB25-LPT-Printer-PCI-E-PCI-Express-Card-Adapter-Converter-/170992964709
[12:34:07] <IchGuckLive> eneuro: what is your maingoal to ratch as you doing workarounds now for days
[12:34:15] <CaptHindsight> $9.48 LPT Printer to PCI-E PCI Express
[12:34:37] <pcw_home> Thats pretty cheap
[12:35:03] <IchGuckLive> this cadr dont support EPP its at HP standard
[12:35:19] <pcw_home> are you sure?
[12:35:54] <eneuro> I'd like to have my LinuxCNC machine.. diskless only ethernet cable and external air for cooling and it looks like it is close to setup this network boot today :D
[12:36:01] <CaptHindsight> WCH CH382L
[12:36:33] <CaptHindsight> good enough for steppers
[12:36:39] <pcw_home> no idea, wonder if theres a data sheet around
[12:36:59] <CaptHindsight> once we start using servos the price of the PC becomes much less of an issue
[12:39:15] <eneuro> IchGuckLive: simply build my own first LinuxCNC machine afterhours ;)
[12:39:40] <IchGuckLive> pcw_home: its a 1284-1994. the epp is at 1997
[12:40:02] <IchGuckLive> eneuro: where are you in the world
[12:40:28] <eneuro> somewhere in Europe ;)
[12:40:36] <pcw_home> EPP predates 1994 so it may well support EPP
[12:40:40] <IchGuckLive> im at the french boarde in germnay
[12:41:51] <IchGuckLive> pcw_home: the 1994 has been ruut in Feb 1994 as there where the Epp lanched and standard changed afrer Feb 1994
[12:42:19] <eneuro> SUN is: 2014-05-22.725 17:23:52 UTC (2456800.225 JD) lat: 5*.****N lon: -2*.***E Sun hour azimuth: -67.121 Sun (geo) azimuth: 247.121 Sun elevation: 7.458 Sun CSP power: 420.9 W Day of the year: 142 :D
[12:42:47] <pcw_home> Yes but it makes no sense that a current chip does not support EPP
[12:43:22] <IchGuckLive> agree on that
[12:43:49] <IchGuckLive> the discription says 1994 not 1997
[12:44:20] <pcw_home> from what I read the very first ieee-1284 standard supports EPP
[12:45:05] <eneuro> ok. I have to find why VirtualBox diskless guest does not boot from my ubunti LinuxCNC TFTP server via network, because this makes me crazy it works on normal PC, but under vbox ;)
[12:45:45] <pcw_home> 1997 just adds parallel device status readback
[12:46:14] <Jymmm> Don't make me pullout my 486 (Circa 1989) and look now =)
[12:46:46] <IchGuckLive> Jymmm: i got one runing
[12:47:01] <Jymmm> IchGuckLive: then look in the BIOS
[12:50:57] <IchGuckLive> Jymmm: only sais ibm parport
[12:51:30] <pcw_home> Nanging QinHeng... but no datasheest of the WCH382 however (only older chips)
[12:51:58] <Jymmm> http://retired.beyondlogic.org/epp/epp.htm
[12:52:09] <IchGuckLive> someone shoudt get one on that price and get it testing
[12:52:54] <Jymmm> EPP version 1.7 was released in 1992
[12:53:45] <Jymmm> ...and later adapted into the IEEE 1284 standard.
[12:54:50] <CaptHindsight> http://wch-ic.com/download/down.asp?id=116 WCH CH352L data sheet
[12:55:21] <CaptHindsight> ● Supporting such as SPP, Nibble, Byte, PS/2, EPP and ECP etc IEEE1284 parallel/printer port modes.
[12:56:03] <Jymmm> http://www.fapo.com/1284faq.htm
[12:56:39] <CaptHindsight> http://wch-ic.com/download/down.asp?id=117 2nd part of DS
[12:56:59] <pcw_home> its probably similar to the 382
[12:57:26] <Jymmm> Why are we having a EP history lesson?
[12:57:30] <Jymmm> EPP*
[12:57:48] <pcw_home> and it says epp mode is supported (though so to NetMOS Chips but they dont)
[12:58:10] <CaptHindsight> have to get one to try and see!
[12:59:00] <CaptHindsight> Jymmm: found a $10 PCIe to EPP card on fleabay new
[12:59:15] <IchGuckLive> ok i got thunder in the region i need to go BYe for today
[12:59:29] <pcw_home> yep, one hopes it just shows up as a parallel port and doesnt require some magic to enable
[12:59:37] <CaptHindsight> hiding under the bed doesn't work
[13:00:04] <PetefromTn_> Anyone got a good spindle or spindle and axis warmup program for LCNC?
[13:00:05] <tjtr33> yeah but dogs dont listen to reason
[13:00:57] <Jymmm> CaptHindsight: nd you think it's bogus somehow?
[13:01:25] <CaptHindsight> looks like some A10/20 tablets have the SPI lines routed on the board
[13:01:32] <jdh> I got some pcie pport cards. they seem to work fine
[13:01:34] <CaptHindsight> Jymmm: we just don't know yet
[13:02:08] <pcw_home> It just that PCIE PP cards have been more expensive so a $10 one is nice if its any good
[13:02:10] <Jymmm> CaptHindsight: how is this any different than a PCI paraport card?
[13:02:25] <pcw_home> fits in a MB with only PCIE
[13:02:48] <Jymmm> pcw_home: sure, but I mean electrically?
[13:02:58] <jdh> I think mine were $30ish. I only use them for pport hardware dongles though.
[13:03:28] <Jymmm> NEVER EVER USE OR BUY ANYTHING WITH A DONGLE, EVER
[13:03:30] <jdh> for $21,000 I can get new versions of WonderWare(tm) that use software or USB keys instead.
[13:04:49] <CaptHindsight> well the card should be here to find out in about 10 days
[13:05:12] <pcw_home> jymmm will chip in...
[13:05:47] <jdh> yeah, I'm sure.
[13:05:47] <Jymmm> ...with ethernet to IO standard
[13:06:31] <jdh> the window maker for the current version I have won't run in Win7 anyway
[13:08:19] <CaptHindsight> http://www.amazon.com/Parallel-Printer-Express-Adapter-Converter/dp/B00BAO55QY $11.98
[13:08:49] <CaptHindsight> ships from China as well
[13:09:04] <pcw_home> its worth $2.00 (well more) not to have to deal with ebay
[13:09:42] <jdh> dunno about that, I can buy stuff from ebay in just a few clicks and not have to type in anything
[13:09:52] <CaptHindsight> six of one half dozen of the other.... I have more issues with Amamzon :)
[13:10:07] <Jymmm> http://paste.ubuntu.com/7502379/
[13:10:13] <pcw_home> kind of like Frys Its worth at least $50.00 not to have to go there
[13:10:25] <CaptHindsight> I agree
[13:11:13] <jdh> I've never been to a Frys. I always assumed it would be cool. Not so?
[13:11:39] <Jymmm> It is, you just have to know the rules =)
[13:12:14] <pcw_home> I have the same reaction to IKEA they treat people like cattle
[13:12:14] <Jymmm> unwritten rules that is =)
[13:12:28] <pcw_home> no thanks
[13:13:22] <pcw_home> But I'm old and crotchety
[13:13:27] <archivist> ikea has short cuts through the store for the intelligent cattle
[13:13:39] <jdh> I've only seen one Ikea
[13:14:00] <CaptHindsight> http://wch.cn/products.php?page=procontent&id=100
[13:14:40] <archivist> I have about 20 ikea bookshelves
[13:15:43] <CaptHindsight> last time at IKEA they wouldn't sell me their industrial shelving
[13:16:22] <CaptHindsight> same for Home Depot, Menards and Loews
[13:16:52] <Jymmm> My entire ikea collection... http://www.ikea.com/us/en/catalog/products/20169658/ which you can mount to your mill or drill press and great shopping bags since stores in the area dont legally offer them anymore for free http://www.ikea.com/us/en/catalog/products/17228340/
[13:17:04] <archivist> you are not supposed to buy parts of the store only the stock
[13:17:18] <CaptHindsight> now you tell me :)
[13:18:32] <Jymmm> pcw_home: you have grocery bag restrcitions in your area?
[13:19:18] <pcw_home> Not yet
[13:19:50] <Jymmm> pcw_home: Ah, SJ, Campbell do now
[13:21:28] <Jymmm> pcw_home: those 60¢ bags are awesome, bought them off amazon as I didn't want to be cattle =)
[13:24:45] <pcw_home> we use re-usable bags anyway and have a good assortment
[13:25:13] <Jymmm> pcw_home: Yeah, I just got tired of having 50 of them is the problem.
[13:26:08] <CaptHindsight> in China they started charging 2-3 cents for plastic bags
[13:26:19] <CaptHindsight> that wouldn't work here
[13:26:53] <Jymmm> CaptHindsight: New law here, no free bags, if you want a paper bag it's 10¢ each or bring your own
[13:27:23] <Jymmm> CaptHindsight: It started as they were clogging the storm drains.
[13:27:39] <CaptHindsight> so similar only 10¢ vs 2-3¢
[13:27:53] <CaptHindsight> they were clogging everything there :)
[13:28:16] <Jymmm> http://plasticbaglaws.org/city-of-san-jose-releases-bring-your-own-bag-ordinance-implementation-results/
[13:28:25] <CaptHindsight> were you getting bag trees?
[13:28:42] <Jymmm> lol, no.
[13:29:01] <Jymmm> Or I guess so if you look at the pic on that link
[13:29:23] <CaptHindsight> http://www.islandbreath.org/2009Year/2009-09/090923plasticbags.jpg
[13:29:36] <Jymmm> ouch
[13:31:09] <CaptHindsight> PC with touchscreen and stepper driver all in one is all I need for simple machines
[13:31:29] <Jymmm> CaptHindsight: sounds scary
[13:31:31] <CaptHindsight> all-in-one box
[13:33:18] <Jymmm> A DVM can't measure a PWM for peak voltage, can it?
[13:33:28] <CaptHindsight> for a few hundred $$, not $1-2k from the usual industrial vendors
[13:33:40] <tjtr33> only freally slow pwm
[13:33:49] <Jymmm> tjtr33: thanks,
[13:34:01] <CaptHindsight> yeah, it will be an average-ish reading
[13:34:13] <jdh> cheap scope
[13:34:53] <Jymmm> I might just hit Fry's Rental dept and grab a scope.
[13:35:06] <CaptHindsight> I just got 2 500mhz 2 channel digital TEK scopes for under $150 ea with shipping
[13:35:31] <CaptHindsight> they just needed the self calibration performed and one need a foot + line code
[13:35:33] <tjtr33> wanna sell one?
[13:35:38] <CaptHindsight> code/cord
[13:35:57] <CaptHindsight> I'll look for more
[13:36:44] <tjtr33> i know the calibration routine. the probes are pricy tho, that pin that auto knows 10x
[13:36:56] <mozmck> CaptHindsight: what is the samples/second?
[13:37:34] <CaptHindsight> 2ghz or 2.5ghz
[13:37:50] <mozmck> Not too bad.
[13:38:35] <mozmck> Are these the newer small form factor?
[13:38:49] <CaptHindsight> people buy them, run the self calibration and turn them around for 3-4x what they bought them for
[13:39:05] <mozmck> where do they get them?
[13:39:27] <CaptHindsight> auctions and fleabay
[13:40:15] <mozmck> ok. I bought an HP 300 mhz with 1 GSa/s a few years back for 300.
[13:40:21] <CaptHindsight> from vendors that don't specialize in instruments, vendors that have appliances and surplus, they don't know or care about reading the docs
[13:40:29] <mozmck> was the best deal I could find at the time.
[13:40:47] <CaptHindsight> they go fast on ebay
[13:41:04] <mozmck> Came with new 500mhz probes too.
[13:41:21] <CaptHindsight> the older ones had leaky caps
[13:41:46] <CaptHindsight> once leaked it would eat up the traces and insulation/coating on the pcb
[13:41:52] <mozmck> I've heard that about Tek, but not HP? mine is about 1996
[13:42:02] <CaptHindsight> hard to re-calibrate after that
[13:42:30] <mozmck> I put a new battery on the main board and everything looked really good.
[13:42:33] <CaptHindsight> if they have't leaked you can swap caps for <$30
[13:43:02] <mozmck> Not so far. I guess just all the electrolytic caps?
[13:44:49] <CaptHindsight> yes
[13:45:10] <CaptHindsight> the peak worst was ~10 years ago
[13:46:18] <archivist> early 1970's in tube equipment caps would leak and make a good mess
[13:46:28] <tjtr33> just spent morning replacing caps, hurco ps should be good to go now
[13:46:33] <CaptHindsight> there was a water based formula for electrolytics that someone stared selling that didn't have all the secret sauce to make it last
[13:47:03] <CaptHindsight> but it was cheaper and it didn't produce defects for months to years
[13:50:43] <archivist> high value resistors fail open, certain polyester caps from the late 1950-1960s fail short, the plastic on some ics taking in water and corroding the internal connections
[13:51:20] <DaViruz> tantalum caps like to fail short as well
[13:52:20] <archivist> yup had many go in amplifiers
[13:54:40] <CaptHindsight> we have lots of simple applications for automation where I'd prefer Linuxcnc or HAL vs a >$1K PLC with touchpanel
[13:55:16] <jdh> we put PC's everywhere. I would generally prefer a plc+hmi if possible
[13:55:25] <CaptHindsight> 1 or 2 axis systems that just move something from one place to another at given intervals
[13:56:12] <CaptHindsight> PLC+HMI if they weren't so pricey
[13:56:34] <jdh> one time cost
[13:56:43] <jdh> vs. pc hell forever
[13:59:31] <CaptHindsight> I have Linuxcnc boxes that are 8 years old without issue
[14:00:32] <Jymmm> CaptHindsight: Where was that bag tree from?
[14:29:47] <PetefromTn> damn just lost my internet ...
[14:30:03] <PetefromTn> I got a little issue guys.
[14:30:31] <PetefromTn> I just had that big blowout on the machine and had to replace a bunch of stuff.
[14:30:51] <PetefromTn> now the machine is working good again and I am trying to make some parts.
[14:31:19] <PetefromTn> however when I went to touch off some new tools they come up with metric numbers.
[14:31:32] <PetefromTn> all the rest of my tools are in inches.
[14:32:15] <PetefromTn> I tried clicking show in inches and metric and back again but the tool table entries enter in metric.
[14:32:31] <PetefromTn> how do you switch that?
[14:33:22] <PetefromTn> DRO's are all inch right now.
[14:34:11] <jdh> m20/m21?
[14:34:57] <jdh> err... g20/g21
[14:36:05] <PetefromTn> hang on lemme try that.
[14:37:00] <PetefromTn> nope still metric.
[14:37:24] <malcom2073> My adapter cables came! Machinekit here I come :-D
[14:38:50] <PetefromTn_> Okay internet is back on
[14:38:52] <jdh> did you change your .ini?
[14:39:01] <PetefromTn_> I did not change anything...
[14:39:12] <PetefromTn_> I only changed the boards in back of the machine.
[14:39:20] <PetefromTn_> Everything else seems to be working perfectly
[14:39:56] <_methods> machine still has params you need to set?
[14:40:07] <PetefromTn_> My DRO's all show inch numbers
[14:40:11] <_methods> wild
[14:40:29] <PetefromTn_> the tool table shows the saved tools I had before the problem and they are in inch.
[14:40:42] <PetefromTn_> Loading new tools the numbers are metric.
[14:40:55] <_methods> in the actual machine, right?
[14:41:03] <_methods> machines tool table not linuxcnc
[14:41:21] <PetefromTn_> LinuxCNC IS the machines tool table.
[14:42:42] <_methods> so what board did you replace?
[14:43:08] <PetefromTn_> 24 volt power supply and the 7i77 mesanet card.
[14:43:12] <PetefromTn_> and some relays.
[14:44:04] <_methods> ah sorry i thought you replaced a board that was on the machine
[14:44:20] <PetefromTn_> there are no more boards on this machine everything back there is brand new.
[14:44:36] <PetefromTn_> This is an linuxCNC issue.
[14:44:50] <PetefromTn_> Just never seen where the numbers loaded were metric.
[14:44:55] <_methods> any dips on the 7i77?
[14:45:07] <PetefromTn_> Would not be a problem if ALL the numbers were metric in the tool table but they are not.
[14:45:16] <PetefromTn_> checked and matched the dips to the old board.
[14:47:12] <_methods> you try makin a new machine from scratch just to see if you have the same issue?
[14:47:57] <_methods> probably not a very helpful suggestion
[14:48:22] <PetefromTn_> LOL hell no man.
[14:48:32] <PetefromTn_> machine is working great again.
[14:48:42] <PetefromTn_> MPG, spindle, coolant, everything works.
[14:48:47] <PetefromTn_> homing limits
[14:49:01] <CaptHindsight> pcw_home: http://www.parallella.org/board/ did you ever get to play with it? get Linuxcnc on it?
[14:49:07] <PetefromTn_> it is all good just dunno why my tool table entries are doing this metric switch.
[14:52:48] <PetefromTn_> any ideas guys?
[14:54:45] <_methods> you try setting inch units in tool.tbl with a text editor and see if they stay inch?
[14:56:44] <PetefromTn_> you mean just open the table in gedit and change or is there a setting for the tool table in the config?
[14:56:51] <_methods> yeah
[14:56:54] <_methods> just use gedit
[14:57:00] <_methods> then reload table
[14:57:13] <_methods> i have no idea just a thought
[14:58:17] <MrHindsight> http://www.aliexpress.com/item/Industrial-grade-touch-screen-embedded-15-inch-LED-all-in-one-computer-6-COM-LPT-Tablet/1446714753.html Bingo
[15:00:09] <PetefromTn_> I guess I can try it but I have retried touching off several times now and deleting the generated numbers and switching show inch and show metric etc.
[15:00:12] <PetefromTn_> No luck so far.
[15:01:28] <PCW> CaptHindsight: is the parallela actually available? last time i looked they had production issues and were not taking orders
[15:04:25] <MrHindsight> PCW: taking new orders but currently out of stock
[15:07:28] <MrHindsight> sorry register to find out about updates to order :/
[15:07:42] <PCW> its interesting and should make a nice linuxcnc platform (though only 24 FPGA I/O bits or so) so about $250 for more I/O and actual connecotrs
[15:10:33] <PCW> The parallela potentially allows making a very high performance headless linuxcnc platform (very high CPU/FPGA bandwidth, good FP)
[15:11:26] <PCW> capable of 20 KHz servo threads or better
[15:13:36] <Jymmm> whats teh easest way to ghetto together a function generator?
[15:13:48] <PCW> ebay
[15:14:05] <Jymmm> PCW: MORE ghetto
[15:14:11] <bertrik> there's this chip that does all basic waves, XR-something IIRC
[15:14:21] <MrHindsight> maybe parallella with A20 daughter card
[15:14:58] <MrHindsight> but its all vapor right now
[15:15:52] <PCW> I suspect they are using the cheapest zynq so 666 MHz dual core
[15:16:00] <bertrik> Jymmm: I was thinking of XR2206 probably
[15:17:11] * Jymmm grabs the laser and heads to richmond!
[15:26:32] <Jymmm> Heym how they do that?! Looked like a clean sinewave https://www.youtube.com/watch?v=YaI6LT233kA
[15:29:26] <demimsy> is there any way to prevent a subroutine from running when another one is already being issued?
[15:30:15] <demimsy> really i would like to wait for the first subroutine to finish then execute the second; however, the second seems to stop the other subroutine
[15:51:49] <MrHindsight> 23" cap touch monitors are under $200 now
[15:52:23] <Jymmm> as they fall off the truck?
[15:52:49] <NickParker|2> Can I use these to drive 5v optos from my 6i25? https://www.sparkfun.com/products/12009
[15:52:57] <NickParker|2> Drive the high side of them that is, low sides are tied together.
[15:53:51] <NickParker|2> er, may have answered my own question. http://dlnmh9ip6v2uc.cloudfront.net/datasheets/BreakoutBoards/Logic_Level_Bidirectional.pdf Looks like the 5v side is just pulled up with a 10k, so it's probably not good for any sane amount of current.
[15:54:50] <MrHindsight> Nick001-shop: should work with optos check how much current drive the optos need for the 6i25
[15:55:15] <NickParker|2> They supposedly need 10mA
[15:55:26] <NickParker|2> but they've got a 10k and a diode built in protecting them
[15:55:32] <NickParker|2> er
[15:55:32] <NickParker|2> a 1k
[15:56:29] <MrHindsight> http://www.adafruit.com/datasheets/BSS138.pdf
[15:57:39] <MrHindsight> but sparkfun soldered in 10k's
[15:58:31] <NickParker|2> Ok I'm silly, dad just suggested a way simpler solution: Just use some 7400 chips that do nothing.
[15:59:04] <NickParker|2> ie for each signal hook it into one side of an OR gate
[15:59:17] <NickParker|2> They can take 3.3v input and put out 5v
[16:01:37] <PCW> probably easier to just use OPTOs with common anode at 5V
[16:02:03] <NickParker> PCW: The optos are built into my driver boards, which I'd really rather not modify in any way.
[16:04:02] <PCW> the 6I25 (and all of our FPGA I/O cards) are designed for active low outputs
[16:04:04] <PCW> so be aware tha active high devices may turn on at power up
[16:05:37] <NickParker> Yeah I caught that bit in the manual.
[16:05:55] <NickParker> My drivers have enable pins that I'm just hooking up to a physical switch.
[16:07:07] <NickParker> I'm gonna run to the local junk shop now for some parts. ty everyone
[16:24:06] <Deejay> gn8
[16:35:02] <tjtr33> ethercat for machinekit http://www.youtube.com/watch?v=M1LxQBjttWg ( posted by Michael Haberler to machinekit mail list )
[16:35:09] <tjtr33> ^^^ real servos on BBB
[16:40:38] <SpeedEvil> PRUs would seem a simpler option
[16:41:18] <PetefromTn_> Well just finished the first program that I ran since I blew up the machine and fixed it. Ran absolutely perfect. I just lived with the metric tool table entries until I can figure out why they are that way. It would be nice to get it fixed because I don't like having to figure out the conversion when I input tool comp adjustments LOL
[16:46:00] <MrHindsight> looks like nobody is going to beat me to ARM + FPGA with HD HDMI, IO, USB + ethernet
[17:06:58] <Jymmm> MrHindsight: Since you seem to have looked intensively at the laser controller pcb, What would you guess the amplitude and max freq would be for the PWM signal going to the laser?
[17:07:30] <Jymmm> I cna't power a laser power meter because ppl wouldn't return them. bastards.
[17:07:33] <Jymmm> But...
[17:08:37] <Jymmm> What I thught was use my killawatt meter and fir the laser from the controller and manually (function generator or pure voltage source) and compare the amperage drawn
[17:09:12] <Jymmm> IF thet are relativelt the same, then the tube is fubar.
[17:09:41] <Jymmm> If not, then the control signal is fubar
[17:09:47] <Jymmm> sound reasonable?
[17:10:38] <CaptHindsight> http://oi61.tinypic.com/153lhtc.jpg laser board
[17:11:23] <Jymmm> CaptHindsight: Yes, thats the pic I posted yesterday
[17:11:59] <CaptHindsight> everything looks like logic level except may that upper right area, didn't examine that closely
[17:12:20] <Jymmm> ttl, as in 3.3v?
[17:12:33] <CaptHindsight> yeah
[17:12:44] <Jymmm> Couldn't be 5v or 12v ?
[17:13:51] <CaptHindsight> the A/D operates from +5 to +15 or dual supplies
[17:14:16] <CaptHindsight> http://www.analog.com/static/imported-files/data_sheets/AD7228.pdf
[17:15:51] <CaptHindsight> the microcontrollers are 5V
[17:17:42] <CaptHindsight> the FIFO is 5V
[17:18:04] <CaptHindsight> https://www.idt.com/document/dst/720072017202-datasheet
[17:18:37] <Jymmm> I'm just not sure what the laser requires to fire at full power.
[17:19:01] <eneuro> Hello linuxcnc-dev ;) Just made working copy "$ git clone git://git.linuxcnc.org/git/linuxcnc.git linuxcnc-dev" and reading README file but can NOT find any ./configure script in linuxcnc-dev/src to compile linuxcnc with simulation enabled? I do not like to destroy this fresh working copy :D
[17:19:52] <CaptHindsight> http://www.xilinx.com/support/documentation/data_sheets/5200.pdf the FPGS IO's were 3v/5V compatible
[17:20:01] <CaptHindsight> FPGA's
[17:21:05] <Jymmm> CaptHindsight: I guess I reallyy can't cinfirm anythign without a scope?
[17:21:10] <Jymmm> confirm*
[17:22:33] <CaptHindsight> http://cdn.liliputing.com/wp-content/uploads/2013/12/a80-optimus-board-680x596.jpg hardly any GPIO
[17:23:06] <CaptHindsight> Jymmm: yeah, all you can do is measure power supply levels or static signals
[17:23:31] <CaptHindsight> <--- walking out the door BBL
[17:23:41] <Jymmm> Bu Bye!
[17:47:32] <Jymmm> Can you take a scope directly to the output of a L298N by chance?
[18:09:35] <eneuro> Who knows if I compile LinuxCNC with "$ ./configure --enable-simulator" hal will be usable? I have starnge message: "It seems that ./configure completed successfully. However, the configuration is for a simulator only, no RT capabilities will be used. In this mode no control of hardware is possible. Drivers won't be built." ????
[18:47:59] <tjtr33> Jymmm, you could try a sample & hold with a peak detector if thats easier than scrounging a scope http://tinyurl.com/ofq6wed
[19:15:27] <Tom_itx> any suggestions getting networking back up on 10.04?
[19:15:44] <Tom_itx> last shutdown things were find but now i can't figure out how to get it connected
[19:21:25] <Tom_itx> or tips on how to diagnose..
[20:03:36] <CaptHindsight> Tom_itx: wired or wireless?
[20:04:07] <CaptHindsight> isn't there a connection manager in 10.04?
[20:05:43] <Tom_itx> wired
[20:05:49] <Tom_itx> it's a software problem
[20:05:57] <Tom_itx> but i can't seem to figure it out
[20:06:18] <Tom_itx> ifconfig shows eth0 but no ip on it
[20:06:33] <Tom_itx> wiring is good, tried different cables etc
[20:07:20] <Tom_itx> it says the cable is disconnected but it isn't
[20:07:37] <Tom_itx> and now the icon for networking is gone at the top right status bar
[20:08:01] <Tom_itx> some stupid gui thing is borked i bet
[20:08:36] <_methods> you hit it with a sudo service networking restart?
[20:08:37] <Tom_itx> i even tried entering a manual ip with no luck
[20:08:47] <Tom_itx> not yet, i'll try that
[20:08:56] <CaptHindsight> ubuntu broke ifconfig
[20:09:14] <CaptHindsight> I'm just glad when the connection manager works
[20:09:19] <_methods> it probably won't work but it's worth a shot
[20:10:07] <Tom_itx> unknown instance
[20:10:15] <Tom_itx> it's not running apparently
[20:10:37] <PetefromTn_> Damn we are getting some NASTY storms here right now..
[20:11:05] <_methods> service --status-all
[20:11:12] <_methods> is networking there?
[20:11:24] <PetefromTn_> My friend who lives a couple miles over has some hail and it is DARK and menacing looking right now LOL
[20:12:23] <Tom_itx> _methods, there's a question mark beside it
[20:12:38] <Tom_itx> network-interface
[20:12:41] <PetefromTn_> what are we talking about here?
[20:12:45] <Tom_itx> network-manager
[20:12:51] <Tom_itx> networking
[20:13:02] <Tom_itx> all [ ? ]
[20:13:26] <CaptHindsight> i think ubuntu has some secret cache for the network config that gets borked
[20:13:56] <PetefromTn_> define borked...
[20:14:02] <Tom_itx> not working
[20:14:09] <PetefromTn_> aah
[20:14:46] <CaptHindsight> http://www.urbandictionary.com/define.php?term=borked
[20:15:45] <PetefromTn_> HEY that is what happened to my machine when I smoked those boards!!
[20:15:46] <_methods> the ? means it's started by upstart
[20:15:49] <Tom_itx> i can use thumbdrive networking but i'd rather not
[20:16:00] <PetefromTn_> sneakernet.
[20:16:01] <_methods> sudo initctl list
[20:16:14] <_methods> will show upstart service status i believe
[20:16:19] <CaptHindsight> I wish uninstalling the app would remove every trace of it
[20:17:16] <Tom_itx> _methods says networking is running
[20:17:34] <_methods> k so it is running
[20:17:43] <Tom_itx> network manager process 771
[20:17:49] <_methods> now just gotta figure out why it's not geting an ip address
[20:18:05] <Tom_itx> network interface eth0 running also
[20:18:09] <_methods> not sure why restart didnt work
[20:18:41] <Tom_itx> networking start/waiting
[20:19:25] <_methods> maybe sudo service network-manager restart
[20:19:34] <_methods> if that's what's makin the problems
[20:21:28] <_methods> wireless is always an adventure with linux for some reason
[20:21:37] <_methods> it's gotten way better though the last few years
[20:22:01] <Tom_itx> that brought back the icon at the top
[20:22:06] <Tom_itx> but no joy
[20:22:09] <_methods> damn
[20:22:27] <Tom_itx> says wired network device not managed
[20:22:37] <Tom_itx> i did enter some manual things in interfaces though
[20:22:42] <Tom_itx> i can remove them
[20:22:53] <_methods> what did you change?
[20:23:10] <Tom_itx> auto eth0
[20:23:28] <_methods> well you're tryin to get your wifi up right?
[20:24:03] <Tom_itx> no, hardwired
[20:24:32] <_methods> oh shit ok
[20:24:38] <_methods> well that's usually easier to fix
[20:26:26] <_methods> did you do ifdown eth0
[20:26:30] <_methods> then ifup eth0
[20:27:13] <XXCoder1> hry sll
[20:27:23] <_methods> sudo ifdown eth0 && sudo ifup eth0
[20:27:41] <Tom_itx> just a sec, it's rebooting
[20:28:01] <_methods> ah
[20:28:19] <_methods> well rebooting is better than what i just said lol
[20:28:35] <Tom_itx> i tried that anyway earlier
[20:28:38] <_methods> yeah
[20:28:46] <_methods> damn wonder if your card is dead
[20:28:57] <Tom_itx> shouldn't be
[20:29:10] <Tom_itx> it's lit up on the switch
[20:29:10] <_methods> what happened to make it go out?
[20:29:17] <Tom_itx> no idea
[20:29:33] <Tom_itx> shut down one day and next time i booted it wouldn't connect
[20:29:42] <Tom_itx> i did make some router changes inbetween
[20:29:47] <Tom_itx> but nothing that would cause that
[20:30:02] <_methods> you dind't do any mac filtering or anything did you'
[20:30:47] <_methods> no make any changes to the dhcp server?
[20:31:01] <Tom_itx> no
[20:31:40] <_methods> only thing i can think of at this point is to wireshark it and see what's goin on that way
[20:31:51] <_methods> see what's goin on with the dhcp requests
[20:32:02] <_methods> are you using dhcp?
[20:32:31] <Tom_itx> yes
[20:32:55] <Tom_itx> i'm gonna sit on it tonight i think. my head's killin me
[20:33:10] <_methods> usually best lol
[20:33:15] <skunkworks_> I have had linksys routers stop communicating with ubuntu machines.. (rebooting them fixed it)
[20:33:24] <Tom_itx> gotta get wireshark on the box first
[20:33:27] <skunkworks_> (rebooting linksys routers)
[20:34:09] <Tom_itx> skunkworks_ this is an ubiquiti edgemax router
[20:34:22] <_methods> nice
[20:34:28] <_methods> i love my ubiquiti
[20:34:29] <Tom_itx> and i've tried rebooting it as well
[20:34:35] <Tom_itx> i have their wifi too
[20:34:39] <Tom_itx> like it as well
[20:34:39] <_methods> yeah me too
[20:34:44] <_methods> i got unifi ap pro
[20:34:52] <Tom_itx> no pro here
[20:34:54] <_methods> i kill all my neighbors lol
[20:34:59] <Tom_itx> yep
[20:35:01] <_methods> i crush all their signals
[20:35:16] <Tom_itx> that's why i got it because of too much local traffic
[20:35:17] <_methods> i have one at 1 and another at 11
[20:35:33] <Tom_itx> do you have an edgemax?
[20:35:36] <_methods> the rest of the neighborhood has to squeezin the middle
[20:35:44] <Jymmm> Tom_itx: why not plug a ether in and get wireshark installed
[20:35:45] <_methods> nah i have 2 ap pro's
[20:35:53] <_methods> he's got it wired
[20:36:00] <Tom_itx> Jymmm how's that gonna work out you ninny
[20:36:20] <Jymmm> Tom_itx: OSI biotch!
[20:36:20] <Tom_itx> eth0 is wired
[20:36:25] <XXCoder1> _methods: mke you house a faraday cage
[20:36:30] <XXCoder1> no mroe outside inference
[20:36:31] <_methods> heheh good idea
[20:36:39] <_methods> my HOA would love that
[20:36:39] <XXCoder1> but then you cant take device outside and expect it to work
[20:36:52] <_methods> plz ignore the metal cage over my house lol
[20:36:53] <XXCoder1> well with network*
[20:37:56] <Tom_itx> i did an ip scan the the other day and found a fed wifi in the neighborhood
[20:38:54] <XXCoder1> cage? why?
[20:38:58] <XXCoder1> just use alum foil
[20:39:02] <_methods> heheh
[20:39:10] <XXCoder1> you gonna use something for windows :P
[20:39:31] <XXCoder1> coat inside (ones that connects to outside) with foil, paint over em
[20:39:35] <XXCoder1> looks awesome I guess? lol
[20:39:43] <XXCoder1> you gonna cover floor and ceiling too lol
[20:40:29] <Jymmm> Tom_itx: Once you get wirehsark installed, you dicount eth0 and bring up wifi and start looking at everythng. from phy all the way up to app layer
[20:41:23] <Jymmm> Tom_itx: what wifi card/chipset you using?
[20:41:47] <_methods> did you try sudo dhclient?
[20:42:08] <_methods> well hell nm you rebooted it should have done that
[20:42:25] <_methods> i have no idea what you have goin on without a wireshark dump
[20:42:26] <Jymmm> And why does ubuntu have so much trouble with wifi, when every othrer debian based distro doens't
[20:43:02] <Tom_itx> Jymmm, i'm not using wifi on this
[20:43:02] <Jymmm> Hell, knoppix does a better job much of the time
[20:44:30] <Tom_itx> i'll try to get wireshark loaded on it
[20:44:41] <Jymmm> Tom_itx: Ah, my mistake. how in the heck did you muck up eth0?
[20:44:48] <Tom_itx> no clue
[20:45:00] <Jymmm> Tom_itx: do you have a 10.04 livecd you could boot from?
[20:45:05] <Tom_itx> sure
[20:45:22] <Jymmm> Tom_itx: try it as a test and see if you have eth0
[20:45:32] <Jymmm> w/o and manual config that is
[20:46:45] <Jymmm> Tom_itx: If it works, then you can dump it's config and compare it to your installed version
[20:46:49] <Tom_itx> what do you push when the cd comes up?
[20:47:00] <Tom_itx> i had to do something to get it to work right but i forgot what
[20:47:11] <Jymmm> F2 ?
[20:47:14] <Jymmm> F10?
[20:47:16] <Jymmm> F12
[20:47:17] <Tom_itx> or i could just reinstall from the live cd
[20:47:21] <Jymmm> to boot to other device
[20:47:29] <XXCoder1> surifcate to gods of linux?
[20:47:34] <Jymmm> No, doent reinstall, you might hav ethe same issue again
[20:48:15] <Jymmm> If the LiveCd works, then you eliminate hardware probelm
[20:50:35] <Jymmm> YAY! My BNC-F to banana scre terminals are on their way!!!
[20:52:34] <jp_mill> Ah finally fixed my stepper stall problem!!!
[20:52:35] <jdh> banana screw terminals?
[20:52:40] <jdh> loose wire?
[20:53:06] <jp_mill> series vs parallel
[20:53:36] <Tom_itx> Jymmm, auto eth0 connection established
[20:53:39] <Jymmm> jdh: http://www.digikey.com/product-detail/en/1452/501-1122-ND/604317
[20:53:42] <jdh> that would do it.
[20:53:44] <Tom_itx> not a hardware issue
[20:54:00] <Tom_itx> but i sorta knew that already
[20:54:10] <jdh> there are bananas inside those posts?
[20:54:33] <Jymmm> jdh: and coconuts too... pina colada time!
[20:54:46] <Jymmm> Tom_itx: Not 100% you didn't =)
[20:54:59] <Tom_itx> sure i did
[20:55:00] <skunkworks_> I was thinking the opposite bnc-f.. think we have a ton of those..
[20:55:04] <Jymmm> Tom_itx: HW failiures happen al the time, never assume
[20:55:16] <jdh> I have the other side BNC with bananas
[20:55:19] <skunkworks_> heh - bnc-m
[20:55:27] <Tom_itx> now, where do i get wireshark for linux
[20:55:41] <Tom_itx> i'll have to put it on a thumbdrive
[20:55:42] <Jymmm> sudo apt-get install wireshark
[20:55:48] <Tom_itx> duh
[20:55:58] <Tom_itx> how's that gonna happen?
[20:56:34] <Jymmm> Tom_itx: right now you look at the net config and compare it to your fubar'ed one
[20:56:40] <Jymmm> mount the hdd
[20:56:54] <Tom_itx> already shut it down
[20:57:23] <Jymmm> Tom_itx I told you to compare it earlier... DUH
[20:57:40] <Jymmm> alright, I'm off to the store
[20:59:51] <Jymmm> Tom_itx: you only need wirehsark if you have intermittant issues. Right not it's purely a config issue that you need to compare to a known good (livecd) with yours
[21:00:13] <Tom_itx> what files should i be looking at?
[21:01:33] <jp_mill> when homing to a limit sw, the DRO should zero out on that axis to whatever the home value is in the ini correct?
[21:06:32] <PetefromTn_> Depends I think there is a couple different Home options.
[21:07:06] <PetefromTn_> http://linuxcnc.org/docs/html/config/ini_homing.html
[21:14:49] <Valen00> ey PCW you about?
[22:11:21] <pcw_home> Yeah
[23:33:19] <zeeshan> is it true you need phase a and phase b
[23:33:24] <zeeshan> to be able to tap on a lathe?
[23:33:47] <zeeshan> or can you get away with index and phase a
[23:34:34] <cradek> to tap you must have a and b, otherwise the reversal can't be measured and followed
[23:35:01] <zeeshan> so basically i need a wheel with 2 different markeings 90 degrees apart
[23:35:11] <zeeshan> 2 different markings sets i mean
[23:35:22] <cradek> no, you need two sensors 90 degrees apart -- i.e. an encoder
[23:35:48] <zeeshan> ah that'll be harder to do
[23:35:51] <zeeshan> will need a fancy bracket
