[03:05:10] <DJ9DJ> morning Jymmm, today I am a few minutes earlier ;)
[03:05:34] <Jymmm> DJ9DJ: Yes, Yes you are.... G'Morning Sir
[03:49:30] <Cylly> moin
[03:49:33] <Cylly> moin
[03:51:33] <DJ9DJ> morning Cylly
[09:40:43] <Jymmm> ReadError: jdh: IF you guys care... http://dx.com/p/universal-intelligent-4-slot-rechargeable-battery-charger-2-flat-pin-plug-100-240v-156756 and http://www.youtube.com/watch?v=Tb1o4lNYNqk
[09:41:22] <Jymmm> ReadError: No USB like I had mentioned before, but does mix chemistry
[10:46:36] <cncinator> hi guys, can anyone tell me why my 2.5.2 doesn't find my freshly inserted tools in the tooltable?
[10:47:31] <Jymmm> Did you restart lcnc?
[10:47:48] <archivist> cncinator, re read the table
[10:48:20] <cncinator> i did, under File and under the tool table
[10:48:27] <archivist> dont have to restart to do it
[10:51:03] <cncinator> restart did it :x
[10:54:35] <cradek> huh, adding a new tool and poking reload tool table works for me
[10:56:22] <cradek> if you can reproduce it, please explain exactly how
[10:58:09] <skunkworks> cncinator: did you try threading yet?
[13:10:43] <cncinator> do i need a index pulse for threading when i have a phase a pulse?
[13:15:56] <pcw_home> if you have only one pulse per turn phase A and index are the same
[13:16:58] <cncinator> i do have only 1 pulse per turn, i get the correct speed output at HAL, but g76 does not move
[13:17:37] <cncinator> it only does the preparation move for the first cut on the X axis, but stays there
[13:19:07] <archivist> have you selected the right mode for a single slot
[13:20:41] <cncinator> what mode?
[13:27:57] <archivist> or connect the index in to the A input, as it is waiting on an index pulse
[13:29:02] <cncinator> you mean a separte cable that connects to the index in to the bob?
[13:29:45] <IchGuckLive> hi all
[13:30:10] <IchGuckLive> second day of total plasma worked fine powermax45 did a 4hr stint
[13:30:20] <IchGuckLive> at 3-12mm
[13:30:31] <IchGuckLive> O.O B)
[13:31:29] <archivist> cncinator, you can do it in hal
[13:32:13] <pcw_home> Yes, inside HAL the parallel port pin that connects to the sensor needs to connect to both A and Index
[13:32:25] <IchGuckLive> does he almost have the trouble with the Z zero
[13:32:38] <IchGuckLive> it is so easy
[13:33:03] <IchGuckLive> i use a Mcode reap to zero the part with G92 Z0
[13:33:24] <cncinator> where do i find the setting in hal?
[13:33:37] <IchGuckLive> you need to write it in
[13:33:58] <IchGuckLive> cncinator: where are you form in the world
[13:34:08] <cncinator> austria
[13:34:12] <IchGuckLive> im in germany
[13:34:21] <IchGuckLive> so it ist better to go german maybe
[13:35:40] <archivist> google is failing to show an example :)
[14:05:06] <IchGuckLive> archivist: http://www.linuxcnc.org/docs/2.4/html/examples_spindle.html#sec:Spindle-Synchronized-Motion
[14:09:48] <skunkworks> cncinator: you need net spindle-phase-z <= parport.0.pin-11-in-not in your hal file - if you don't
[14:10:31] <skunkworks> sorry
[14:10:41] <skunkworks> cncinator: you need net spindle-spindle-index <= parport.0.pin-11-in-not in your hal file - if you don't
[14:11:15] <skunkworks> cncinator: you alrady have net spindle-phase-a <= parport.0.pin-11-in-not
[14:23:11] <skunkworks> jeeze!!!
[14:23:38] <cncinator> hi skunkworks
[14:23:42] <skunkworks> cncinator: net spindle-index <= parport.0.pin-11-in-not
[14:23:51] <skunkworks> wait
[14:24:26] <cncinator> ok
[14:24:47] <skunkworks> Hi
[14:24:52] <cncinator> hey :)
[14:26:15] <cncinator> net spindle-index <= parport.0.pin-11-in-not just gives that allready used pin error
[14:29:21] <cncinator> how to link something that isn't linkable?
[14:29:36] <archivist> he also says something like net parport.0.pin-11-in-not => spindle-index => spindle-phase-a fails with error line 54: Pin 'spindle-index' does not exist
[14:31:07] <Skullworks> SF mailing list down?
[14:33:02] <Skullworks> last digest I received was Vol 83, Issue 26 a week ago.
[14:33:52] <cpresser> cncinator: most likely parport.0.pin-11-in-not is already connected to a net
[14:34:01] <cpresser> see if you can rename that net to 'spindle-index'
[14:34:40] <cncinator> ofc its allready connected, i only have one sensor for 'spindle-index' and 'spindle-phase-a'
[14:34:46] <mrsun> hmm using wick feed oiler or drip feed .. that is the question :P
[14:35:13] <skunkworks> cncinator: give me a second.. ;)
[14:35:21] <archivist> cncinator, net parport.0.pin-11-in-not => spindle-index => spindle-phase-a connects two at a time it should work
[14:36:06] <archivist> mrsun, both about the same
[14:37:23] <mrsun> do they booth keep feeding oil till its empty if the oil leaks some or is one of them better? :)
[14:37:24] <cncinator> nope, that just gives Pin 'spindle-index' does not exist
[14:37:31] <mrsun> if you forget to turn of the drip feeder :P
[14:43:00] <skunkworks> archivist: you cant connect a signal to a signal
[14:43:06] <skunkworks> I think
[14:43:47] <archivist> should be able to connect inputs together
[14:46:09] <skunkworks> encoder.0.phase-Z
[14:46:33] <skunkworks> heh
[14:46:37] <skunkworks> net spindle-phase-a encoder.0.phase-A encoder.0.phase-Z
[14:46:39] <skunkworks> net spindle-phase-b encoder.0.phase-B
[14:46:41] <skunkworks> #net spindle-index encoder.0.phase-Z
[14:47:15] <skunkworks> then net spindle-phase-a <= parport.0.pin-11-in-not
[14:47:25] <skunkworks> try that
[14:47:38] <cncinator> evrything into the .hal?
[14:50:39] <skunkworks> well - you need to see what is there and modify..
[14:51:14] <cncinator> it starts now
[14:52:29] <skunkworks> but does it work?
[14:54:10] <cncinator> wohoo
[14:54:16] <cncinator> its threading NOW :D
[14:56:20] <skunkworks> Yah!
[14:57:10] <cncinator> it threaded air, just to test - but i dont think it used the backlash compensation
[15:04:21] <DJ9DJ> threaded air... to put siemens lufthaken in it?
[15:04:58] <cncinator> lol yeah ^^
[15:05:13] <DJ9DJ> ^^
[15:09:35] <skunkworks> cncinator: we also need videos.. :)
[15:10:19] <skunkworks> do you still have net spindle-position encoder.0.position-interpolated => motion.spindle-revs
[15:10:22] <DJ9DJ> yeah, otherwise it did not happen ;)
[15:10:27] <skunkworks> change in your hal file?
[15:19:42] <cncinator> my machine did the best threading job i ever saw in her life!!
[15:19:58] <cncinator> and its rlyrly much faster then with mach3
[15:20:00] <cncinator> amazing
[15:20:49] <archivist> cncinator, when you get brave internal threads http://www.collection.archivist.info/archive/DJCPD/PD/2012/2012_05_06_Leawood/IMG_1240.JPG
[15:22:36] <skunkworks> cncinator: Great!
[15:24:37] <cncinator> archivist, i'll try internal tomorrow- have to rewrite all my old mach3 codes
[15:26:20] <cncinator> that feed correcture is amazing
[15:26:41] <cncinator> i havnt saw that in mach3, guess thats why i had 2 pitches sometimes
[15:27:01] <cncinator> "on the fly correction"
[15:27:12] <archivist> mach is screwed up with regard to threading
[15:29:02] <cncinator> have to upload a image now ^^
[15:30:57] <cncinator> http://i49.tinypic.com/v76xco.jpg
[15:31:02] <cncinator> first linuxcnclathe job M14x1
[15:32:39] <archivist> :)
[15:34:53] <cncinator> thank you guys, again
[15:35:01] <skunkworks> pretty!
[15:35:35] <cncinator> cant understand now why some ppl still use mach3 lol
[15:36:10] <skunkworks> they are all waiting for mach4 ;)
[15:37:21] <cncinator> mach4 got discontinued... ?
[15:37:37] <skunkworks> no - it just isn't out yet.. been years.
[15:38:12] <cncinator> at the arcsoft forum it says they implented the "worked on mach4 features" just to mach3 and thats it :x
[15:42:54] <skunkworks> any video? ;)
[15:43:51] <cncinator> need my telephone to hang out the window for 3g tethering xD
[15:44:03] <cncinator> ill do one tomorrow with internal threading
[15:44:36] <cncinator> or do you want a external thread?
[15:45:42] <skunkworks> whatever you got ;)
[15:46:01] <cncinator> ill do what u want :P
[15:46:06] <cncinator> int / ext?
[15:46:31] <skunkworks> ext
[15:46:41] <cncinator> dimension?
[15:47:34] <cncinator> stainless / alu?
[15:49:14] <skunkworks> oh - whatever you are working on. Don't do anything special..
[15:49:56] <cncinator> ;)
[15:53:41] <cncinator> thanks again, and bb until tomorrow :)
[17:34:28] <asdfasd> just burned a CD with last linuxcnc, but when boot asking for user and pass, I cant find anything about that, how to login
[17:34:54] <Jymmm> hit enter
[17:35:38] <asdfasd> authentification failure
[17:35:44] <asdfasd> and then start over again
[17:36:18] <Jymmm> Didn't it ask you during install for a userid to create?
[17:36:30] <asdfasd> not installed yet
[17:36:36] <asdfasd> first boot from cd
[17:36:55] <Jymmm> downoaded from where?
[17:37:20] <asdfasd> http://linuxcnc.org/index.php/english/download
[17:37:31] <asdfasd> EU mirror
[17:37:46] <asdfasd> then md5 check fine
[17:37:52] <asdfasd> then burned a CD
[17:37:59] <asdfasd> then boot from CD
[17:46:31] <asdfasd> it look like bad CD on the next boot show something different, Im going to burn now another CD
[17:49:21] <DJ9DJ> gn8
[17:52:51] <skunkworks> asdfasd: is it a text login? or gui?
[17:57:18] <asdfasd> gui, but the CD is bad, now Im burning another
[18:09:43] <asdfasd> now installation begin properly, it look like linux smell my fear :)
[18:20:56] <Skullworks> The trick to being a computer Wizard is having a full collection of curses as well as mastery of shell commands.
[18:39:03] <Jymmm> Ah hell no... fdisk, dd, and a stack of OS ISO's is all ya need.
[18:39:57] <Jymmm> rsync doens't hurt either
[18:42:51] <cpresser> real wizards use butterflies. http://xkcd.com/378/
[18:54:59] <asdfasd> installed, now charge pump frequency too high, can I make it 5khz
[19:04:27] <andypugh> asdfasd: I would imagine so.
[19:08:19] <Tecan> is there such thing as a compressed file system ?
[19:08:33] <Tecan> for main os use
[19:09:25] <Tecan> guess thats what the archive is fore, just most of the time large archives are slow to use
[19:11:23] <andypugh> There used to be, but I think it rarther went out of fashion.
[19:11:39] <cpresser> some are still used for read-only filesystems
[19:11:49] <andypugh> http://en.wikipedia.org/wiki/Doublespace
[19:12:06] <asdfasd> andypugh: the input optocoupler for charge pump is slow, and cant pass through higher than 5khz
[19:12:29] <andypugh> I have been in the workshop, and not paying attention.
[19:12:39] <cpresser> Tecan: i recall that there is also a rw-fs for FUSE
[19:12:42] <andypugh> What sort of system is it?
[19:13:34] <andypugh> asdfasd: If you are running charge-pump in software then it always runs at the base thread rate
[19:13:46] <andypugh> (probably 20kHz or so)
[19:14:15] <andypugh> If you need a slower one, consider using one pin of a velocity-mode quadrature-mode stepgen
[19:19:25] <asdfasd> I will try now...
[19:20:08] <Tecan> seems the bigger my home lucks partition gets the more crunching happens at boot
[19:20:20] <Tecan> luks
[19:22:36] <Tecan> fuse sounds fn rad
[19:24:13] <Tecan> need that for my videogames
[19:26:10] <pcw_home> for 500 Hz you can toggle an output pin at the servo thread rate
[19:26:37] <Tecan> manually ?
[19:26:49] <Tecan> hehe
[19:27:27] <pcw_home> Thats pretty fast for manual....
[19:27:53] <andypugh> Yes, good point, addf the charge pump to the serv-thread instead and see what happens
[19:29:58] <andypugh> I think I need a bigger milling machine. https://plus.google.com/photos/108164504656404380542/albums/5747722155741347649/5856099195071654466?banner=pwa
[19:31:37] <andypugh> Hard to hold-down work when it is bigger than the table.
[19:35:38] <pcw_home> rather hard to reach the center of the work as well
[19:42:59] <Skullworks> andy - what do you have on there for a spindle motor?
[19:43:30] <Skullworks> for the mill spindle
[19:51:14] <pfred1> who wrote the configure script for LinuxCNC?
[20:03:58] <andypugh> Skullworks: It's a 750W 3-phase motor. I gave up on the original DC motor when the commutator went, and took the drive with it.
[20:05:43] <Skullworks> I picked up an AL framed 1.1Kw 4 pole 3ph to put on my wobbly Seig X3.
[20:06:54] <andypugh> Pretty much the same idea, then.
[20:06:57] <Skullworks> figured anything bigger would help the machine destroy its self
[20:07:36] <andypugh> If I was doing it again I would just ignore the gears in the head and have a direct belt drive, just for quietness.
[20:08:14] <andypugh> As it is, I replaced the gars with steel ones, and converted it to oil-filled.
[20:08:35] <Skullworks> thats my plan 1.5 to 1 underdrive and over speed the motor
[20:09:13] <andypugh> The oil-filled conversion was basically just a sheet of brass shim beteen the two castings, and an oil seal at the bottom.
[20:09:16] <Skullworks> for tapping torque
[20:09:32] <Skullworks> what type oil?
[20:10:39] <andypugh> Some random gear oil I had lying about :-)
[20:11:06] <andypugh> This was an interesting setup for the oil seal. (the mill was in bits, see) https://plus.google.com/photos/108164504656404380542/albums/5747722155741347649/5598931059779269058?banner=pwa
[20:30:55] <skunkworks> andypugh: how is the other mill coming?
[20:31:51] <andypugh> Slowly. Though I used it today
[20:32:06] <andypugh> I have a motorised Z and manual XY at the moment
[20:32:29] <skunkworks> neat
[20:32:46] <andypugh> Y just needs the 8i20 fitting and the servo tuning
[20:33:23] <andypugh> X needs a casting, a ballscrew, a nut....
[20:33:39] <skunkworks> That will be a nice stout machine
[21:38:17] <tjb1> Anyone have a pentagon drywall hoist?
[21:39:03] <jdh> nope, only a hexagon
[21:39:08] <pcw_home> does that only work on pentagonal sheetrock?
[21:39:16] <tjb1> It's a brand
[21:39:34] <pcw_home> no one here but us SAs
[21:39:37] <tjb1> They have a 6020 model and a 6022 model and the only difference I have found is the color
[21:39:38] <jdh> mine's not really so much a drywall hoist as a 1/4-20 nut
[21:40:12] <tjb1> Harbor Freight only had part A but not part B?
[21:45:26] <jdh> just a hexagon
[21:59:30] <uminded> Anybody know why my stepgen.0.step is always FALSE? http://pastebin.com/BUngrTRH
[22:07:33] <andypugh> uminded: What's the step-length?
[22:09:24] <uminded> I tried 1, 10, 100 and the dir pin is toggling but not the step
[22:15:12] <Valen> its quite possible that you just aren't seeing it
[22:16:39] <uminded> I moved my net to dir. I know my driver is working now.
[22:16:59] <uminded> What would be a good test to see how fast of a step train I can output?
[22:17:51] <pcw_home> the latency test
[22:19:02] <uminded> what command should I run, just the basic latency-test and capture its output
[22:23:21] <uminded> better yet, any test that doesnt require a display
