[00:13:38] <R2E4> I fried my BBB
[00:13:51] <eric_unterhausen> how'd you do that?
[00:14:32] <R2E4> I got one of those devel capes, and put a terminal between the gnd 5 and 3v
[00:14:50] <eric_unterhausen> that will do it
[00:14:52] <R2E4> I attached the gnd and dont know why, I put 5v on the 5v termnal
[00:15:30] <R2E4> oh yeahdeader than OBL
[00:16:39] <R2E4> was checking my vmc tonight getting ready for retrofit to LinuxCNC
[00:16:52] <R2E4> The plc has 45 relays on it.
[00:17:25] <eric_unterhausen> do you have a schematic?
[00:17:46] <eric_unterhausen> the moore at work has relays driving relays
[00:17:46] <R2E4> I need to buy a boatload of relays but thats going to cost.
[00:18:00] <eric_unterhausen> automation direct
[00:18:23] <R2E4> yeah, schematics, manuals etc...... It all shows about a million contacts
[00:18:42] <eric_unterhausen> that's my favorite
[00:18:52] <R2E4> I have a dl06
[00:18:56] <eric_unterhausen> for whatever reason, the schematics with relays drive me crazy
[00:19:05] <R2E4> and the ZIP I/O expansion
[00:19:56] <R2E4> IT has a 20 position ATC on it.Cant figure that one out yet
[00:20:10] <eric_unterhausen> those things are magic
[00:20:20] <eric_unterhausen> the people that made it probably barely understood it
[00:20:27] <eric_unterhausen> "ship it!"
[00:20:34] <R2E4> The three axis I dont think I'll have a problem with but the spindle servo and the ATC.....
[00:20:42] <R2E4> Dont know if it is going to work.
[00:20:55] <eric_unterhausen> what's so hard about the spindle servo?
[00:21:23] <R2E4> It has weird inputs
[00:21:30] <eric_unterhausen> that will do it
[00:21:38] <eric_unterhausen> like what?
[00:22:33] <R2E4> let me find it
[00:23:05] <R2E4> magnet seperator..... WTF is that?
[00:23:47] <eric_unterhausen> it's a signal?
[00:23:54] <R2E4> Theres 8 motors not including the axis servos
[00:25:45] <R2E4> ok,
[00:26:09] <R2E4> SP Forward, SP reverse, SP orientation SP low gear
[00:26:19] <R2E4> sp tool unclamp
[00:27:42] <eric_unterhausen> that's interesting, they use the magnets for clamping or something?
[00:27:42] <R2E4> looks like transistor turning on relay and its sending ground through each of those
[00:28:47] <R2E4> theres a relay to remove the z axis brake in that schematic
[00:30:21] <R2E4> ITs documented really well, problem is you cant follow anything through it with the machine wiring
[00:33:06] <R2E4> the magnet seperator is a motor
[00:33:59] <R2E4> ITs a fanuc module for the spindle servo
[00:34:19] <eric_unterhausen> that's horrible
[00:34:19] <eric_unterhausen> I am not a huge fan of little number labels on wires, but it sure beats no labels
[00:34:19] <eric_unterhausen> yeah, but what do the magnets do?
[00:34:20] <eric_unterhausen> part of a brake?
[00:35:30] <R2E4> I dont know yet
[00:36:27] <R2E4> sp speed check signal, sp certain speed signal sp zero speed signal spindle alarm orientation finish
[00:37:03] <eric_unterhausen> so it's some stuff to avoid having to do logic in the computer
[00:37:17] <R2E4> theres a cutting monitor output out of the sp servo amp
[00:37:59] <eric_unterhausen> that's cool, wonder how that works
[00:38:07] <eric_unterhausen> are they injecting a signal?
[00:38:20] <eric_unterhausen> or current monitor?
[00:39:07] <R2E4> its an output, to monitor when cutting, dont know how they would do that unless they are measuring the load
[00:39:26] <R2E4> theres a load meter and rpm meter
[00:42:23] <R2E4> I am scared I wont get the spindle servo working, the xyz axis should be no problem
[00:42:35] <R2E4> Then theres the 6 million relays
[00:42:43] <eric_unterhausen> it's possible that some of the complexity can be ignored
[00:43:10] <R2E4> Thats probable
[00:43:46] <R2E4> halogen lamps, I dont even know where they are....hehe
[00:46:42] <R2E4> This machine has a pallet option. Mine doesnt have a pallet changer etc..... but its in the manual, so I have to weed it out.
[00:51:52] <somenewguy> well hopefully you see them before they see you
[00:51:56] <somenewguy> no one likes a surprise hallogne
[00:51:57] <somenewguy> haloegn
[00:52:04] <somenewguy> hal... o forget it i'm goin to bed
[00:55:25] <R2E4> hahaha, magnet seperator motor to inline downstream from coolant pump to remove To remove chips from a sump continuously in an external pumping circuit
[00:59:51] <R2E4> Fanuc Spindle drive A06b-6055-h103
[03:08:22] <Deejay> moin
[03:15:44] <rootB> Hey linuxCNC has anyone here gotten the TB6600 working?
[05:31:54] <jthornton_> rootB, there is some chatter on the forum about the tb 6560 or something like that
[07:37:46] <JT-Shop> hi ho it's off to work we go
[08:06:54] <Jymmm> CNC Power Supply Capacitors... BEMF-Be-Gone http://www.youtube.com/watch?v=EoWMF3VkI6U
[08:21:00] <MrSunshine> yeah! got a package full of router bits today ... but the router is in little bits and pieces :P
[08:28:49] <archivist> kit
[08:31:45] <Jymmm> Nice... http://www.youtube.com/watch?v=GPJao1xLe7w
[09:52:05] <IchGuckLive> hi all B)
[10:02:14] <IchGuckLive> <- hopes all UK cnc friends are still powered and no water in the shop
[10:06:27] <CaptHindsight> Jymmm: the down side is the very high inrush current when the caps have discharged, the alternator will need current limiting since the inrush current can be in the 1,000's of amps if there are good clean connections between alternator and caps
[10:06:53] <Tom_itx> can someone point me to the current 2.6 git source/
[10:06:53] <Tom_itx> ?
[10:08:29] <IchGuckLive> Tom_itx: why not the buildbot
[10:08:42] <IchGuckLive> http://buildbot.linuxcnc.org/
[10:08:42] <Tom_itx> because the deb isn't current
[10:08:57] <IchGuckLive> it is stable and best to go
[10:09:10] <Tom_itx> this is for testing
[10:09:23] <IchGuckLive> master branch is from 2nd jan
[10:09:30] <IchGuckLive> so its 2 days old
[10:09:45] <Tom_itx> i tried using the deb and it's broke
[10:10:25] <CaptHindsight> ask in the dev channel
[10:10:45] <Tom_itx> i think they sleep longer than you
[10:10:47] <Tom_itx> :_
[10:11:15] <IchGuckLive> Tom_itx: for standard or xenomai
[10:11:20] <CaptHindsight> it's saturday
[10:11:33] <Tom_itx> i'm not too sure of the difference IchGuckLive
[10:11:55] <Tom_itx> probably standard
[10:11:59] <IchGuckLive> at the Realy front end there is no more ubuntu all devs are at xeno
[10:12:17] <Tom_itx> i wanted to test the new TP
[10:12:49] <Tom_itx> what linux flavor are they using?
[10:13:34] <zultron> What're you trying to do, Tom_itx ?
[10:13:53] <Tom_itx> just do some testing
[10:14:08] <Tom_itx> i wanted to test the new TP out on some hardware for them
[10:14:12] <zultron> Current 2.6 git source is always at git.linuxcnc.org
[10:14:27] <IchGuckLive> Tom_itx: git clone git://git.linuxcnc.org/git/emc2.git tomtest
[10:14:49] <IchGuckLive> git reset --hard origin/master
[10:15:01] <zultron> There you go. :)
[10:15:04] <IchGuckLive> then you are at the front end
[10:15:13] <Tom_itx> then i need to add in the new TP code
[10:15:16] <IchGuckLive> standard ubuntu
[10:15:21] <zultron> I don't think the new TP code is in master, though.
[10:15:26] <Tom_itx> no it isn't
[10:15:44] <Tom_itx> skunkworks was gonna help me install that i believe
[10:15:54] <IchGuckLive> its maybe in cradeks git
[10:16:00] <IchGuckLive> or jepplers
[10:16:04] <Tom_itx> newer than that
[10:16:55] <Tom_itx> the new trajectory planner from robert
[10:17:24] <IchGuckLive> just make a git commit an someone will fill it in the nightly
[10:17:34] <Tom_itx> http://www.youtube.com/watch?v=oUajH5BCOUQ&feature=c4-overview&list=UUHk52YjGT8HryRYmJKSl-lg
[10:17:51] <Tom_itx> looks quite promising
[10:18:57] <IchGuckLive> my simple gcoe maker pocket can do this for years
[10:19:28] <Tom_itx> the read ahead difference is what is impressive
[10:19:29] <IchGuckLive> with chexckbox start inside outside finish rouph
[10:19:43] <Tom_itx> same feed/speed
[10:20:44] <IchGuckLive> just commit it and someone will take care
[10:20:59] <Tom_itx> i'm also new to git :)
[10:21:17] <Tom_itx> always learning
[10:21:19] <Tom_itx> never stop
[10:21:53] <zultron> https://github.com/robEllenberg/linuxcnc-mirror/
[10:22:24] <zultron> That's where the new TP code is being developed. I don't know which branch he's committing to, though. :-/
[10:23:08] <zultron> But the circular-blend-arc-alpha branch was updated 2 days ago.
[10:23:15] <zultron> https://github.com/robEllenberg/linuxcnc-mirror/branches
[10:23:16] <Tom_itx> he built from cradek's code i think
[10:23:18] <IchGuckLive> he is committing against master 2.5.1
[10:25:04] <zultron> I don't understand? Ellenberg's work is based on either master or 2.5, yes.
[10:25:55] <zultron> His working version should be in the above repo, and you can clone your own copy.
[10:26:02] <IchGuckLive> its not master ists the standard branch
[10:26:11] <zultron> https://github.com/robEllenberg/linuxcnc-mirror/tree/circular-blend-arc-alpha
[10:26:43] <zultron> I see.
[10:28:11] <IchGuckLive> as it is a compiled bug fix
[10:28:51] <IchGuckLive> so the fix shoudt be in 2.5.3 already
[10:29:16] <IchGuckLive> im off BYE till later
[10:33:05] <CaptHindsight> besides boat anchor and target practice what do you do with your old 90's era PC's?
[10:33:22] <Tom_itx> rob parts
[10:33:37] <Tom_itx> bench supply with the psu
[10:34:08] <Tom_itx> if it were gold you could retire
[10:35:56] <archivist> if they have a parallel port and enough memory and pass a latency test, use them
[10:36:33] <CaptHindsight> current ubuntu won't install
[10:36:48] <atom1> i had to put 8.04 on one of mine
[10:37:01] <atom1> still runs 2.5 though
[10:37:03] <CaptHindsight> they have Fedora 5-6 on them from 05'
[10:37:49] <CaptHindsight> i think they all have less than a few days of service
[10:37:53] <archivist> I was just looking earlier, two machines are running in 256 meg of ram
[10:38:38] <atom1> i assume you run git as root
[10:39:12] <CaptHindsight> these might have 32 or 64mb, whatever was the min for win95
[10:39:12] <atom1> ?
[10:45:19] <atom1> ok what does: git reset --hard origin/master do?
[10:45:26] <atom1> i get errors executing that
[10:46:11] <cpresser> atom1: i will drop all changes in your current local branch and switch to the branch (eg. checkout) origin/master
[10:57:26] <Jymmm> CaptHindsight: inrush current to/from where, and when?
[11:04:21] <CaptHindsight> Jymmm: current from the alternator into the caps
[11:05:14] <Jymmm> CaptHindsight: And why couldn't those caps in that config take it?
[11:05:30] <CaptHindsight> say you leave the light on the car for a few hours
[11:05:35] <Jymmm> k
[11:05:45] <Jymmm> Well, few minutes =)
[11:06:17] <CaptHindsight> the caps will be like a dead short across the alternator terminal at 0.0007 ohms
[11:06:33] <Jymmm> ah, I see what youre saying
[11:06:51] <Jymmm> Just can't drain them to zero volta (so to speak)
[11:07:27] <ReadError> CaptHindsight: not worth the power to run
[11:08:43] <CaptHindsight> the other problem will be if the car doesn't start after cranking, no reserve capacity
[11:10:05] <CaptHindsight> if you could make them cheaply there was a good idea in the comments about a small battery in parallel with the supercaps to have some reserve
[11:11:34] <CaptHindsight> or just use lithium like the batteries in electric vehicles
[11:12:14] <R2E4__> outputs on 7i77, they outputting the positive or the negative side of field power?
[11:14:01] <R2E4__> I have 12vdc relays and supplying 24vdc field power. Can I trigger the gnd for the relays?
[11:14:19] <CaptHindsight> sure
[11:15:08] <CaptHindsight> oh, but let me check the 7i77
[11:16:07] <Jymmm> JT-Shop: http://www.youtube.com/watch?ca7ZPfkcNqA
[11:16:31] <pcw_home> 7I77 outputs are sourcing outputs (so supply field power to the load)
[11:17:22] <R2E4__> I think they source positive side, which would suck
[11:17:43] <CaptHindsight> yes ^^
[11:18:04] <R2E4__> ok, thanks pcw, then my idea wont work
[11:19:29] <pcw_home> if you have all 12V relays, then use 12v field power
[11:19:55] <R2E4__> I have a mix of relays, 12 and 24
[11:20:20] <pcw_home> thats awkward (and a bit odd)
[11:20:28] <R2E4__> Most of what is in the machine is 24v relays, so I will have to go with 24vdc and obtain more 24vdc relays
[11:21:10] <R2E4__> TYhe plc has around 50 relays in it
[11:21:39] <pcw_home> if you need more outputs that the 7I77 has you can add another remote I/O at another field voltage
[11:22:59] <R2E4__> ah yeah, didnt think of that. will see. I may try and keep the board with all the relays on it and cut the traces and create my own relay board using the existing relays. The plc board has all the relays soldered on it.
[11:23:52] <pcw_home> there is a sinking driver as well if that makes wiring easier (7I72)
[11:23:59] <R2E4__> I'm coming to grips with the drawings, I dont know who did them but they suck....
[11:24:30] <R2E4__> Cant match and trace from drawing to machine
[11:24:30] <eric_unterhausen> drawings always suck
[11:25:02] <pcw_home> Onsemi has a new driver chip that has eight 1/2 bridges so we may eventually have individual sink/source ability
[11:25:14] <R2E4__> The bridgeport drawings are fantastic. Every line and point has a number kkwhich is matched by number label on the wire.
[11:25:18] <CaptHindsight> http://www.youtube.com/watch?v=ylOQq_nnNYs a much better glue gun extruder
[11:25:38] <R2E4__> ah cool.
[11:26:21] <R2E4__> The fanuc spindle driver will be another point of frustration and irritation....lol
[11:28:16] <pcw_home> what interface?
[11:28:35] <R2E4__> not sure yet
[11:28:45] <pcw_home> PN?
[11:29:06] <R2E4__> A06B-6055-103
[11:36:39] <R2E4__> http://irmtl.com/LinuxCNC/VM40/SPdwg.JPG
[11:36:51] <R2E4__> its upside down......I'll fix it
[11:37:48] <pcw_home> Oww
[11:38:58] <pcw_home> looks like just plain old analog
[11:42:01] <R2E4__> The DAO you think is the inmput?
[11:42:15] <pcw_home> (VCMD1 and VCMD2)
[11:42:46] <pcw_home> DA2 31,32
[11:44:13] <R2E4__> ah Jeez... I was looking at Analog out thinking it was out of the SP. Now the 16-2 is the conroller, so that makes sense.
[11:44:27] <R2E4__> Regular spindle PWM output of the 7i77?
[11:45:25] <pcw_home> probably OK but you may want a common mode choke on the 2 wires to keep HP noise from the spindle drive out of th other axis
[11:46:39] <R2E4__> ok,
[11:46:55] <R2E4__> Its coming together slowly, but surely.
[11:47:05] <R2E4__> I need a plan....
[11:49:28] <R2E4__> Have to go overthe ladder diagrams and count actually how many relays is required.
[11:50:05] <R2E4__> Then start looking at how the ATC works.
[11:51:39] <pcw_home> Yeah at some point you will need to understand that to implement the control (in classic ladder, a comp or whatever)
[11:55:19] <atom1> yay! got 2.6 built
[11:56:06] <CaptHindsight> success!
[11:58:38] <atom1> must be sim only?
[12:01:05] <CaptHindsight> pcw_home: were you able to get or even try Axis with your fpga + cubie setup?
[12:01:06] <IchGuckLive> hi all B)
[12:01:43] <atom1> IchGuckLive, got 2.6 built thanks
[12:01:57] <IchGuckLive> nice
[12:02:28] <atom1> the TP was for 2.5 though right?
[12:02:34] <pcw_home> No, I have not had time to mess with it
[12:02:48] <CaptHindsight> we can try next week
[12:03:35] <CaptHindsight> pcw_home: how far along did you get? kernel + linuxcnc installed with some IO activity?
[12:05:54] <pcw_home> I have not actually done anything with the Cubie just made the FPGA daughtercard and then got dragged into other things
[12:06:50] <CaptHindsight> ok, just wondering how much left we have to do
[12:07:24] <CaptHindsight> pcw_home: does the fpga take the place of the baseboard?
[12:11:13] <pcw_home> Yes the Cubie sets on top and you get 3x 50 pin I/O connectors
[12:11:14] <pcw_home> (plus the normal Cubie I/O is relayed to 2x 50 pin 2 mm connectors)
[12:11:38] <CaptHindsight> great, we can finish up the software
[12:11:53] <pcw_home> (since the FPGA interface only uses about 6 I/O pins)
[12:13:25] <pcw_home> well maybe 8 I forget
[12:14:06] <CaptHindsight> just going to control 1-2 steppers and a few I/O at first
[12:58:21] <IchGuckLive> im off BYE have qa nice day where ever you are in the world
[13:14:21] <CaptHindsight> http://oliviervanherpt.nl/3d-printed-beeswax/ now you can really mind your own beeswax
[13:35:11] <lbl> Hi i just wanted to thank the people who helped me yes today ... the spindle is working perfectly now
[13:35:11] <owhite> hey people. I built an instance of linux on 12.04 using xenomai from the documentation found here: http://www.anderswallin.net/2012/12/linuxcnc-on-ubuntu-12-04lts/
[13:35:26] <owhite> The compile worked, the tests look good.
[13:35:54] <owhite> the compile was done with run-in-place
[13:36:10] <owhite> but I cant find an executable for linuxcnc. Any suggestions?
[13:37:09] <CaptHindsight> owhite: did you install or build linuxcnc as well?
[13:37:35] <CaptHindsight> or just build and boot a xenomai kernel?
[13:37:44] <owhite> I ran make and sudo make setuid
[13:38:09] <CaptHindsight> on what system?
[13:38:31] <CaptHindsight> there are also RTAI debs for 12.04
[13:38:47] <eric_unterhausen> my 27" monitor from woot just came in
[13:39:07] <eric_unterhausen> I think I'll install one of those evil nvidia cards and see if I like it
[13:39:18] <owhite> oh, I found some documentation saying RTAI has not been kept up to date.
[13:39:29] <CaptHindsight> yeah, thats old info
[13:39:37] <CaptHindsight> it was updated over the summer
[13:39:38] <owhite> so I used: http://www.anderswallin.net/2012/12/linuxcnc-on-ubuntu-12-04lts/
[13:40:24] <CaptHindsight> owhite: ok so you started with Ubuntu 12.04 and now have a xenomai kernel, now you have to install Linuxcnc
[13:40:24] <owhite> yeah there's a lot of out of date information for linuxcnc.
[13:40:50] <owhite> Capt: yes. I've compiled linuxcnc as well.
[13:41:34] <owhite> and ran the tests successfully described on that page.
[13:41:52] <CaptHindsight> here are the RTAI debs http://www.linuxcnc.org/seb/rtai-for-3.4-prerelease/
[13:42:05] <owhite> thanks.
[13:42:45] <owhite> but I could install those, reboot to that kernal, install the linuxcnc src, recompile, and end up with the same problem. Yes?
[13:43:14] <CaptHindsight> let me find a more complete howto
[13:44:05] <CaptHindsight> not sure what you did to end up without an executable
[13:45:53] <owhite> well it made lots of others :-)
[13:47:45] <owhite> I was trying to do this but couldnt get he RTAI deb to work: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?LinuxCNC_On_Ubuntu_Precise
[13:48:36] <CaptHindsight> yeah thats the latest I know of
[13:49:04] <CaptHindsight> ask in #linuxcnc-devel they are looking for more feedback
[13:49:26] <CaptHindsight> the debs work
[13:49:43] <CaptHindsight> must be some detail you're missing
[13:49:48] <owhite> in the web page or using the link you have above?
[13:49:50] <CaptHindsight> detail/step
[13:50:42] <CaptHindsight> seb just updated that wiki page to the latest info
[13:51:07] <CaptHindsight> my link earlier was just to the git for the debs
[13:51:36] <owhite> okay let me step through it and I'll see where it chokes. hang on.
[13:51:42] <CaptHindsight> they have been updating the dev tree
[13:52:05] <owhite> rebooting the cnc box to a generic kernal
[14:03:09] <owhite> wow apt-get install linuxcnc seems to be working.
[14:04:02] <eric_unterhausen> that's all 32 bit
[14:04:12] <eric_unterhausen> if you are running 64 bit it doesn't work
[14:06:05] <owhite> yeah, I installed a fresh 12.04 32-bit
[14:06:44] <owhite> latency-test is failing, complains "locked memory limit is 64kiB"
[14:06:55] <eric_unterhausen> ya, there is a fix for that on the wiki
[14:07:24] <owhite> :-)
[14:07:48] <owhite> sorry trying to solve issues without dragging other people into it. :-)
[14:08:12] <eric_unterhausen> don't worry, I was whining quite a bit when I was going through that process a week ago
[14:08:33] <eric_unterhausen> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?LockedMemory
[14:09:12] <CaptHindsight> 64bit RTAI is working but I don't think there is a wiki page for it
[14:09:51] <eric_unterhausen> the reason I didn't do the 64 bit was I didn't want to build from source
[14:10:01] <owhite> oh hm the linuxcnc installation seems to have performed that fix.
[14:10:07] <eric_unterhausen> and right now the unified build is a work in progress
[14:10:21] <eric_unterhausen> owhite, you might have to reboot
[14:10:35] <owhite> yeah that's a lot of compiling. I spent a good part of 16 hours yesterday trying that.
[14:10:44] <owhite> okay, will reboot.
[14:12:33] <owhite> damn I wish I could get grub to default to the startup menu
[14:13:01] <eric_unterhausen> I used the graphical grub boot editor on the ubuntu forums
[14:13:30] <CaptHindsight> I'm going to enjoy the warm weather today (-3C) before it gets cold -32C tomorrow
[14:13:47] <eric_unterhausen> http://askubuntu.com/questions/100232/how-do-i-change-the-grub-boot-order
[14:14:12] <owhite> thanks eric_unterhausen
[14:14:29] <eric_unterhausen> first answer. I've heard that they considered changing the name from grub2 to "boot obfuscater"
[14:14:48] <eric_unterhausen> but decided that was too much truth for the linux community to swallow
[14:15:17] <owhite> the reboot worked, and man do i have some nice max jitter numbers.
[14:15:34] <eric_unterhausen> do a stress test
[14:15:58] <owhite> oh yeah that. I was thinking of running six compiles while doing the latency-test :-)
[14:16:03] <eric_unterhausen> my max jitter was fine until I stressed it a little
[14:16:19] <eric_unterhausen> it turned out on my system that the best stress test was to go to utube
[14:16:43] <eric_unterhausen> someone suggested not going to utube, but that didn't work either
[14:17:07] <owhite> redtube.com :-) ?
[14:18:02] <Loetmichel> re @ home
[14:18:19] <owhite> installing flash seems to be slowing it down pretty good too. :-)
[14:18:38] <eric_unterhausen> once I went to the vesa vid drivers, my latency was fine
[14:18:56] <eric_unterhausen> went up from the unrealistic 4000nS to about 15nS
[14:19:14] <owhite> yeah I'm getting those kind of numbers as well.
[14:19:26] <eric_unterhausen> sorry, 15uS
[14:19:58] <CaptHindsight> what cpu's and chipsets?
[14:20:22] <owhite> I have a mini-ITX running atom and I believe it's 1.8Ghz
[14:21:02] <eric_unterhausen> I have an athlon dual core 2.5ghz on an asrock 790gx
[14:21:14] <owhite> hey I'm just happy I successfully installed linuxcnc.
[14:21:26] <owhite> oh, and dont have to use liveCD.
[14:21:41] <eric_unterhausen> are you going to be using software stepping?
[14:21:52] <owhite> you mean steppers? Yes.
[14:22:30] <eric_unterhausen> you could be using steppers with a mesa or pico system too, just wondering how important latency was
[14:22:49] <owhite> I'm using a mesa.
[14:23:06] <eric_unterhausen> ok, so latency is not that important
[14:23:19] <owhite> upgrading from a pico - which I liked but I'm making a new control board for my laser.
[14:23:53] <eric_unterhausen> any reason why you didn't just go with the livecd?
[14:24:27] <owhite> the 10.04 OS didnt drive my wifi board.
[14:25:08] <owhite> and dont quote me on it but I also think it wasnt driving my display very well.
[14:25:59] <eric_unterhausen> the splash screen on ubuntu 12 is better than the 10 splash screen
[14:26:12] <eric_unterhausen> but I'm not sure about once you get into the OS
[14:26:45] <owhite> I wasnt going to mention the cosmetic stuff, but yeah the 10.04 just looks and feels downright old.
[14:28:44] <eric_unterhausen> I am not a big fan of transparent desktop objects, but I have gotten used to them
[14:29:38] <Loetmichel> owhite: hmmm
[14:29:47] <owhite> ?
[14:30:12] <Loetmichel> first thing i do when istalling a new win7: select design "windows Classic"
[14:30:23] <Loetmichel> ... i LIKE the 10.04 desktop!
[14:30:33] <eric_unterhausen> windows classic has some annoyances though
[14:30:43] <eric_unterhausen> I use an XP system and it drives me nuts
[14:31:04] <eric_unterhausen> I remember when I first got used to XP and then winNT would drive me nuts
[14:31:20] <owhite> well if we're comparing OS's let me tell ya I just became a macOS convert after 10 years of resistance.
[14:31:42] <eric_unterhausen> you can get used to anything
[14:31:55] <eric_unterhausen> I hated unity when it first showed up, but now I'm used to it
[14:32:06] <owhite> install parallels on macOS and you can run any microsoft OS you want. It's amazing.
[14:32:20] <eric_unterhausen> the fact that 10.04 would randomly lock up and 12.04 didn't was a big aspect of that
[14:39:55] <eric_unterhausen> there is so much bad information out there about video cards
[14:40:09] <eric_unterhausen> or rather, changing them on ubuntu
[14:40:25] <eric_unterhausen> I think I might just plop the new card in and hope that it works
[14:40:39] <owhite> outdated docs?
[14:41:59] <eric_unterhausen> ubuntu no longer uses xorg.conf
[14:42:12] <eric_unterhausen> it uses some obfuscated magic
[14:42:18] <Deejay> in 12.04 it does
[14:42:46] <eric_unterhausen> it can, but it doesn't unless you force it to
[14:43:08] <eric_unterhausen> for example, neither of my 12.04 systems us xorg.conf
[14:43:09] <Deejay> yep, if there is no xorg.conf, it gets the information from somewhere else
[14:43:54] <Deejay> first thing after installing was to create xorg.conf and setup everything correctly ;)
[14:44:01] <eric_unterhausen> I think that may help me in this situation
[14:44:12] <Deejay> using xorg.conf I at least know what to do ;)
[14:44:47] <eric_unterhausen> if everything goes right, it's easy to troubleshoot the new way of doing things
[14:45:10] <eric_unterhausen> of course, if everything goes right, you don't need to troubleshoot
[14:45:46] <eric_unterhausen> they have adopted the microsoft method where you can't go onto the internet to complain if the computer doesn't boot
[14:46:06] <Deejay> hrhr
[14:46:34] <eric_unterhausen> I was on a help chat session with HP service and they kept urging me to reboot
[14:46:57] <eric_unterhausen> of course, at that point I would be disconnected from them, so it would not count against their statistics
[14:47:10] <Deejay> lol
[14:49:12] <owhite> hey eric_unterhausen - thanks for your help today - I got rtai debs installed, linuxcnc installed on 12.04 and that grub-customizer is really cool too. Thanks.
[14:49:21] <owhite> see everyone later!
[15:40:39] <Jymmm> When you're not sure what to do with a spare 5+HP Motor... http://www.youtube.com/watch?v=GnZUkl0NC5A
[15:45:16] <eric_unterhausen> changing monitors means cleaning the desk == too much work
[15:45:24] <Jymmm> JT-Shop: New accessory for your tractor http://www.youtube.com/watch?v=NTbUrCTJF1I
[15:45:36] <eric_unterhausen> but at least now I know why there aren't any pens in the house
[16:11:47] <R2E4__> Can I connect one of these directly to 7i77? http://irmtl.com/LinuxCNC/VM40/MPG/mpg1.JPG
[16:12:11] <R2E4__> inside http://irmtl.com/LinuxCNC/VM40/MPG/mpg.jpg
[16:14:10] <andypugh> I would think so, yes.
[16:14:26] <andypugh> It looks ot be a simle TTL type single-ended encoder
[16:14:58] <Tom_itx> andypugh do you know where the git is for 2.5.3?
[16:15:31] <andypugh> I don't think I understand the question
[16:15:51] <Tom_itx> where do i find the source
[16:16:03] <andypugh> Where are you looking?
[16:16:16] <Tom_itx> i pulled master from 2.6 today
[16:16:22] <Tom_itx> that's all i've done
[16:16:37] <Tom_itx> but i wanted to test that new TP code
[16:16:46] <Tom_itx> someone suggested it was for 2.5
[16:16:49] <andypugh> It's all the same archive, just checkout v2.5_branch
[16:17:08] <Tom_itx> ok, i'm still learning git as well but i think i can do that
[16:17:26] <Tom_itx> i did get 2.6 compiled and ran it
[16:17:48] <andypugh> "git checkout v2.5_branch" will probably automatically create a new tracking branch and switch to it, as i accidentally found out earlier
[16:18:16] <Tom_itx> where does it put the compiled output?
[16:19:33] <andypugh> Over the top of the 2.6 Run-in-place unless you tell it otherwise
[16:20:19] <Jymmm> HEs probably happier than a clam with his new splitter, but I feel bad for the poor bastard ... http://www.youtube.com/watch?v=8nBhc35ucVk
[16:21:29] <Jymmm> Not sure what's worse, moving the logs, or having to stoop down and hold the button liek that
[16:22:16] <Tom_itx> andypugh how do i use git to check for new changes since i have already downloaded the code?
[16:26:59] <Jymmm> Tom_itx: http://wiki.spheredev.org/Git_for_the_lazy#View_changes
[16:38:42] <Jymmm> JT-Shop: So, how good with your tractor are you??? http://www.youtube.com/watch?v=CuGBpwnWW2I
[16:39:05] <andypugh> Tom_itx: It will tell you if a branch is out of date when you check it out, but I tend to just refexively "git pull"
[16:39:50] <Meduza> how high supply voltage is it reccomended to use with tb6600 drivers?
[16:39:53] <Deejay> gn8
[16:40:03] <uw> bye Deejay
[16:40:14] <Deejay> bye bye uw
[16:40:23] <Jymmm> DN9
[16:40:29] <Deejay> and all others ;)
[16:40:30] <Jymmm> GN9
[16:40:35] * Deejay hugs Jymmm ^^
[16:40:54] <Meduza> is a good switched 48V supply advisable to use?
[16:40:58] <skunkworks> Tom_itx: get master then get this https://github.com/robEllenberg/linuxcnc-mirror/tree/circular-blend-arc-alpha
[16:41:11] <Tom_itx> skunkworks i got master earlier today
[16:41:16] <Tom_itx> compiled 2.6
[16:41:27] <Tom_itx> where do i put that code?
[16:41:32] <Tom_itx> in the same project directory?
[16:41:37] <skunkworks> wait
[16:41:49] <skunkworks> let me find the commands
[16:41:53] * uw waits
[16:42:13] <andypugh> Meduza: It's generally better to not use a switched PSU. The right transformer, rectifier and caps wil tend to be tougher and better for the load (you don't really need good regulation)
[16:42:59] <andypugh> A switched high frequency supply and a switched high frequency load can (I have heard) sometimes not play well together
[16:45:17] <Meduza> i have used switched supplys both with leadshine DM drivers and allegro based ones with no problem
[16:46:07] <Meduza> even if i added a large capacitor just to be sure when using higher current
[16:47:03] <Meduza> the question is more about how sensitive the Toshiba drivers are
[16:49:24] <Meduza> is the 50v max claims correct or is it a spec too much on the limit
[16:49:47] <Jymmm> ...and does it include BEMF too?
[16:50:45] <Meduza> so will a 48v supply blow the drivers at the first time the motors brake or will it work fine
[16:51:11] <jdh> let us know
[16:51:40] <Jymmm> Redneck towtruck... AWESOME http://www.youtube.com/watch?v=mVDzB6mvCgU
[16:51:52] <skunkworks> Tom_itx: http://pastebin.ca/2528184
[16:52:06] <skunkworks> from that point - you build it as you would master
[16:52:11] <Meduza> i have tried the tb6560 before and they were quite sensitive. thought someone in here would have tried the newer higher power tb6600
[16:52:37] <Meduza> so i didn't had to blow one :)
[16:52:39] <skunkworks> (you already pulled master - then you con
[16:52:44] <atom1> skunkworks, do i put it in the same directory as master?
[16:53:29] <skunkworks> you go into the directory master is in - then run the 'remote add command and on..'
[16:53:51] <skunkworks> (you don't have to run the first command as you already have master)
[16:54:11] <skunkworks> if that makes sense
[16:54:18] <atom1> what's circ stand for just out of curiosity?
[16:54:31] <eric_unterhausen> well, ubuntu worked with the new graphics card once I set my bios right
[16:54:58] <Meduza> the thing is that i am trying to help a younger friend (17) to build his first cnc router and i dont have any transformers in the right size just lying around but could give him a 48v 12A switched supply that I have :)
[16:55:13] <skunkworks> atom1: that is what I called the directory that I put master in
[16:55:35] <skunkworks> you use whatever directory you pulled master into'
[16:55:58] <atom1> right
[16:56:40] <atom1> multitasking here but i will catch up on what you're telling me soon
[17:12:27] <kengu> what is the chinese ripoff version of this: http://www.geckodrive.com/geckodrive-step-motor-drives/g540.html
[17:14:32] <eric_unterhausen> doubt they would bother to clone that
[17:59:47] <R2E4__> Do I need these buttons?
[17:59:51] <R2E4__> http://irmtl.com/LinuxCNC/VM40/IMG_0403.JPG
[18:00:43] <eric_unterhausen> ya, every one
[18:04:57] <R2E4__> That sucks, cause none of dem work....hehe kaboshed!!!
[18:05:38] <andypugh> You have a 7i77?
[18:05:39] <R2E4__> gots to cut that monitor out, and recreate a mount for a computer linuxcnc monitor.
[18:06:10] <R2E4__> yup
[18:06:36] <andypugh> If those are a matrix keyboard (which seems very likely) then you could probably interface them via a 7i73 connected to the 7i77
[18:07:25] <R2E4__> If you look up closely, most of them are warn out down to the underlying button. no skin left
[18:07:47] <andypugh> Ah, OK, then start from scratch
[18:08:19] <andypugh> You can still use a matrix keyboard and a 7i73 if that suits you
[18:08:24] <eric_unterhausen> haas has a lot of buttons too, don't really see the need
[18:09:10] <R2E4__> I need more i/o which is important. Havent figured out which card I am going to use to connect to 7i77
[18:12:16] <andypugh> You can also wire a matrix KB to GPIO using the matrix_kb HAL component which can be a lot more economical than wiring each button directly. (for example, an 8x8 matrix is 16 HAL pins and 64 buttons). Note that the buttons don't have to be physically in a matrix, they just need to be wired that way
[18:12:58] <eric_unterhausen> the moore control we have has 8 buttons, more than enough
[18:13:04] <R2E4__> thats a good idea.
[18:13:14] <andypugh> This picture (not my workshop) shows a rather nice scratch-built console that a chap I know made for hois lathe: https://picasaweb.google.com/lh/photo/Qll6-unQntbnBFe2fjfNbSE34QWor4gUzfw_1O9qsPw?feat=directlink
[18:13:35] <eric_unterhausen> one is hydraulic power, don't think you need that
[18:14:41] <eric_unterhausen> looks like a really nice panel, too bad there is no straight on view
[18:14:52] <R2E4__> here is ATC... http://irmtl.com/LinuxCNC/VM40/ATC/IMG_0411.JPG http://irmtl.com/LinuxCNC/VM40/ATC/IMG_0416.JPG
[18:15:29] <eric_unterhausen> the machine looks pretty clean, how is it inside?
[18:16:24] <R2E4__> PLC http://irmtl.com/LinuxCNC/VM40/PLC/IMG_0388.JPG http://irmtl.com/LinuxCNC/VM40/PLC/IMG_0395.JPG http://irmtl.com/LinuxCNC/VM40/PLC/IMG_0410.JPG
[18:16:59] <R2E4__> Inside cabinet... http://irmtl.com/LinuxCNC/VM40/Control%20Cabinbet/cab1.JPG
[18:17:39] <R2E4__> All the pics I took today are here. http://irmtl.com/LinuxCNC/VM40/ Been working oncleaning it.
[18:20:01] <eric_unterhausen> I think I see two lube/hydraulic pumps?
[18:20:27] <eric_unterhausen> mpg looks simple enough
[18:21:58] <eric_unterhausen> you might not need anything more about the servo amps than the simple schematic that you have
[18:23:17] <FinboySlick> pcw_home: Got a couple minutes to spare?
[18:23:44] <eric_unterhausen> just ask
[18:24:05] <FinboySlick> eric_unterhausen: Me you mean?
[18:24:15] <eric_unterhausen> ya
[18:24:38] <FinboySlick> This isn't really linuxcnc related. Just something I know pcw_home might have insight on.
[18:25:31] <eric_unterhausen> irc protocol is to ask the real question, no preamble
[18:26:13] <andypugh> FinboySlick: I know a fair bit about Mesa stuff, especially the LinuxCNC interface
[18:26:37] <FinboySlick> eric_unterhausen: Technically, the C part of IRC is for chat but fine.
[18:27:46] <FinboySlick> andypugh: It's not Mesa related either. Just trying to figure out what might be wrong with a mobo and he's the only guy I know with good insight on that kind of circuitry. Wondering what might cause pre-kernel clockspeed to sink horribly. Are those regulated by capacitors usually?
[18:28:32] <eric_unterhausen> how do you know pre-kernel clockspeed is sinking?
[18:29:19] <FinboySlick> eric_unterhausen: It's mostly a guess, it takes ages to get through POST, grub, decompressing the kernel. Once it's decompressed, things are at a normal speed.
[18:30:14] <FinboySlick> Since there were no hardware or environmental changes, I'm thinking it's a faulty component.
[18:30:39] <eric_unterhausen> all motherboard problems are capacitor related
[18:30:49] <FinboySlick> The seconds countdown in grub (when you make selection) take about 30 seconds per second to count down.
[18:31:07] <eric_unterhausen> Chinese cap manufacturers are now working hard to make sure there is no cosmetic evidence of failed caps
[18:31:32] <eric_unterhausen> weird
[18:32:10] <FinboySlick> So it's as if post used one clock and the kernel used another or some odd thing like that.
[18:32:19] <eric_unterhausen> do you really think that post is slower?
[18:32:44] <eric_unterhausen> the cpu controls the clock, your bios may have gone wanky
[18:33:30] <FinboySlick> Could be. Just don't know enough hardware to know if it really is the CPU or some sort of reference clock circuitry.
[18:34:03] <FinboySlick> The CPU is performing quite well now that it has loaded the kernel.
[18:34:29] <FinboySlick> (I'm using the machine right now)
[18:35:21] <FinboySlick> Whatever is wrong during POST and BIOS is still wrong during GRUB and the decompressing bit of loading the kernel.
[18:35:41] <eric_unterhausen> the kernel sets a batch of chipset/cpu registers
[18:36:00] <eric_unterhausen> you can look in dmesg to see if there are any hints
[18:36:40] <eric_unterhausen> you also may want to turn off the graphical boot and watch the boot messages scroll by
[18:36:49] <FinboySlick> There's no graphical boot.
[18:37:07] <eric_unterhausen> what os?
[18:37:31] <FinboySlick> It's a custom gentoo setup.
[18:38:28] <FinboySlick> I'm parsing dmesg now to see if I notice anything odd.
[18:38:53] <atom1> skunkworks, seems to be compiling
[18:39:10] <atom1> can i copy my configs into this once it's done?
[18:43:29] <FinboySlick> Nothing out of the ordinary... I'll try to reset/flush everything bios related.
[18:57:40] <skunkworks> atom1: I think so - just be sure to add the required settings to the traj section of the ini
[18:59:10] <atom1> where are the compiled files located?
[19:00:26] <skunkworks> ARC_BLEND_ENABLE = 1
[19:00:27] <skunkworks> ARC_BLEND_FALLBACK_ENABLE = 1
[19:00:29] <skunkworks> ARC_BLEND_OPTIMIZATION_DEPTH = 50
[19:00:30] <skunkworks> ARC_BLEND_SMOOTHING_THRESHOLD = 0.4
[19:00:32] <skunkworks> ?
[19:00:48] <atom1> ahh yeah for the new planner
[19:02:09] <atom1> make: cscope: Command not found
[19:02:10] <atom1> make: *** [cscope] Error 127
[19:02:40] <skunkworks> well - install cscope..,.
[19:03:45] <atom1> once it compiles, where are the output files located?
[19:03:55] <atom1> so i can edit the ini etc to add my configs
[19:05:20] <atom1> what's it mean to run in place? just a sim?
[19:05:46] <skunkworks> oh - once it compiles - they are in the directory that you built it in - rip
[19:07:01] <skunkworks> so you go into that directory - type . ./scripts/rip-enviroment
[19:07:05] <skunkworks> then linuxcnc
[19:12:06] <skunkworks> it should see your configs if they are in the normal linuxcnc directory..
[19:12:09] <FinboySlick> Hmm... Well it's fixed now but I'm not sure what it was.
[19:12:48] <atom1> they are
[19:13:14] <atom1> well... i think they are
[19:39:19] <andypugh> Night all
[20:04:56] <skunkworks> Tom_itx: any luck?
[20:35:32] <Tom_itx> yeah
[20:35:43] <Tom_itx> i gotta copy over some configs though
[20:35:48] <Tom_itx> on the other hdd
[20:35:56] <Tom_itx> i swapped them out to avoid any problems
[21:05:29] <atom1> skunkworks, not sure what's going on just yet. it tries to load the config then quits
[21:06:30] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/cnc/configs/sherline/bitfiles/dmesg.txt
[21:06:36] <Tom_itx> there's the dmesg output from it
[21:07:18] <Tom_itx> oh wait.. do i need to edit the configs?
[21:11:31] <atom1> same thing after adding the ARC_BLEND stuff
[21:21:17] <atom1> hmm, any ideas?
[22:08:56] <eric_unterhausen> well, my garage door is on the internet
[22:15:25] <Jymmm> sounds like a dumb idea to me
[22:15:34] <eric_unterhausen> ya, bad ideas abound
[22:15:47] <eric_unterhausen> you have to enter a code to open/close
[22:16:03] <Jymmm> Dont forget to post your ATM PIN number too
[22:17:03] <eric_unterhausen> there's only 10000 of them
[22:17:31] <Jymmm> not necessarily
[22:17:41] <eric_unterhausen> it's probably not as bad as your bank forcing you to have an online account
[22:20:46] <eric_unterhausen> I should look at my internet traffic, it's probably sending out packets at some rate
[22:29:55] <eric_unterhausen> I figure my family leaving the garage door open because they are a batch of flakes was going to cost me some tools at some point
[22:30:06] <eric_unterhausen> and so now I can check the door if I want
[22:34:39] <Jymmm> you could jsut set a 2hr timer to automatically clsoe the garage door
[22:34:57] <Jymmm> ...with a 5 minute warning
[22:35:55] <FinboySlick> Oooh! Make that a 100HP air raid siren ;)
[22:36:12] <FinboySlick> It'll break the habit of forgetting it open ;)
[22:37:35] <eric_unterhausen> I tried installing the app on my wife's phone, her password didn't work
[22:37:53] <eric_unterhausen> I tried to get her to try to login on her computer, too lazy, will do it tomorrow
[22:38:34] <Jymmm> Install a trian horn IN the house, when the garage is left open more than 15 minutes.... GUARNTEE it'll with =)
[22:38:45] <Jymmm> work*
[22:39:11] <eric_unterhausen> when you open the garage door from the internet, the opener beeps like crazy
[22:39:14] <Jymmm> No internet, no passwords, no too lazy for this, or forgot that, bullshit
[22:39:15] <eric_unterhausen> dogs love that
[22:39:58] <eric_unterhausen> this is how spammers get gmail addresses
[22:41:31] <Jymmm> eric_unterhausen: So now Google has access to your home =)
[22:42:00] <Jymmm> physical access that is
[22:42:55] <eric_unterhausen> I was too lazy to put the deadbolt on the door, so you can just lift the garage door anyway
[22:43:05] <Jymmm> lol
[22:43:52] <eric_unterhausen> If I lived somewhere with a higher crime rate, I'd worry about it
[22:44:03] <RyanS> This is odd.. Goliath gun & spiral flute taps with TiN coating are 20% cheaper than bright.. wtf.
[22:44:31] <RyanS> Unless that's a large quantity discount
