[02:09:20] <MrSunshine> http://www.youtube.com/watch?v=b1RSl1m5AxY this is the setup i want to use to grind my spindle, but how to indicate that the spindle is straight? (the lathe chuck will never rotate at all) =)
[02:17:52] <archivist> for what definition of straight
[02:18:41] <Deejay> moin
[02:27:55] <MrSunshine> archivist, that the inner spindle shaft is in lign with the lathe in both planes =)
[02:28:32] <archivist> get an alignment bar
[02:28:47] <MrSunshine> in the spindle shaft?
[02:28:51] <MrSunshine> collet
[02:28:52] <MrSunshine> etc
[02:30:14] <archivist> http://www.arceurotrade.co.uk/Catalogue/Measurement/Parallels-Angle-Blocks-Test-Bars
[02:30:21] <archivist> bottom of the page
[02:30:59] <archivist> but first is the bed beyond reproach
[02:32:00] <archivist> a test bar turned between centres to check
[02:32:35] <archivist> any bed twist? do you have a proper level
[02:33:08] <archivist> wear, is the saddle low near the chuck
[02:33:45] <MrSunshine> does it realy mater over such a short distance for a ER collet, i want to regrind the spindle that is in the lathe spindle ... so a testbar i guess wont do me any good as the spindle will be in the way :P
[02:34:14] <archivist> cheap ER are not good for testing against
[02:35:23] <MrSunshine> even if they have some runoff they should be quite straight right? and was thinking to use several collets with several bars and even out the tests
[02:35:45] <archivist> the test bar tell and its use will help you diagnose
[02:36:24] <archivist> the ER chucks I have tried are terrible
[02:36:41] <Jymmm> WHOA 1TB SSD $600 (on sale)
[02:37:39] <MrSunshine> ive checked the bore of my spindle and its off by about 0.08mm and im going to try and correct that without destroying the spindle but that i guess you already know .. problem i have is to get everything in a straight line to eachother, the spindle motor and the grinder =)
[02:37:40] <archivist> the contact length of the collet in the holder is too short to keep it in line,
[02:38:22] <archivist> dont you want to set it at an angle(morse)
[02:39:21] <archivist> have you checked bearing play yet
[02:40:58] <MrSunshine> gonna check it some more before i start the grind but gonna set it up in the lathe so its more rigid than where it is right now =)
[02:41:00] <archivist> I ask that as the act of turning in a loose bearing could show that amount of error
[02:42:54] <MrSunshine> archivist, bearings in what? my spindle motor or the lathe? =)
[02:43:21] <archivist> holding the spindle you are measuring
[02:44:15] <archivist> here I ŧhink you may have to get things right in sequence else you may make it worse
[02:46:04] <MrSunshine> =) gonna check more when ig et it in a more rigid setup .. like in the lathe it goes into for grinding, cause atm on my machine its a bit to flexible to check play etc :P
[02:47:57] <archivist> if dont in its own bearings it has to be right, using another lathe is difficult
[02:48:06] <archivist> dont/done
[02:48:44] <MrSunshine> i have a very hard time to follow what you say :P
[02:49:05] <MrSunshine> the spindle will rotate itself while i grind it, i just use the lathe for holding it in place
[02:50:09] <archivist> your statement "like in the lathe it goes into for grinding" implied you are taking out of one lathe and grinding in another
[02:50:54] <archivist> and at the moment I dont know where you think the errors are
[02:51:07] <MrSunshine> archivist, no, sorry .. this is one of those cheap china spindles (router spindles) =)
[02:51:51] <MrSunshine> http://img.b2bage.com/photo/product2/117268/big-3kw-cnc-router-spindle-motor.jpg
[02:52:31] <archivist> ah crappy er nose
[02:52:46] <MrSunshine> yes =)
[02:53:06] <MrSunshine> hehe , hard to help and explain when no one knows what they are helping with :P
[02:56:59] <Jymmm> Um, I think if i walked into a store asking for "blank cassettes", I'd get a lot of deer-in-the-headlight looks... http://www.frys.com/product/6630354?site=sa:adpages%20page:P6_FRI%20date:012414
[06:57:36] <jthornton> getting meaningful names without name conflicts and run on is fun in python
[07:02:06] <skunkworks> it is probably an art
[07:02:32] <jthornton> lol, and I'm not an artist
[07:03:49] <jthornton> it is fun learning python, gtk and glade
[07:07:47] <Tom_itx> 9° F
[07:08:11] <jthornton> 7f
[07:08:26] * Tom_itx feels much warmer alread
[07:08:28] <Tom_itx> y
[07:40:37] <eric_unterhausen> 5F here
[07:41:26] <eric_unterhausen> gotta go into New York to get into negatives today
[07:42:09] * archivist cuddles a mug of coffee to warms his fingers
[07:50:23] <Tecan> its going to get cold again starting next month
[08:48:07] * JT-Shop suits up in the carhartt's to take the puppy out
[09:00:16] <Vq> jthornton: It is an art and it's not constrained to Python.
[09:01:39] <Vq> "There are only two hard problems in Computer Science: cache invalidation and naming things." -- Phil Karlton
[09:02:35] <archivist> cache too small by one byte, enjoy watching your disk thrash
[09:07:31] <JT-Shop> Vq, I've learned a lot about naming things lately
[09:13:18] <Vq> namespaces and scopes are your friends
[09:17:10] <archivist> google images is failing me today, old Sheffield comparator, earlier version I think
[09:33:15] <JT-Shop> namespace I'm not familiar with other than knowing it is there somewhere, self. is my friend in python
[09:37:52] <Jymmm> archivistI dont think it's you. It's been mucking up for a few days now.
[09:47:04] <archivist> I find the newer shape but not the old shape like I have
[09:50:02] <archivist> I got mine working a year ago but had lost the lid, started making a wooden replacement, today having a tidy found the original lid, can chuck it back together now
[09:54:53] <pcw_home> "There are only two hard problems in Computer Science: cache invalidation and naming things." -- Phil Karlton
[09:54:54] <pcw_home> I thought it was:
[09:54:56] <pcw_home> "There are only two hard problems in Computer Science: cache invalidation, naming things, and off by one errors"
[09:59:03] <Jymmm> Eh, the joke is missing Floating Point =)
[10:00:03] <Jymmm> assuming off by one is 012 instead of 123
[10:01:32] <archivist> sometimes it morphs to "There are only 10 hard problems in Computer Science: cache invalidation, naming things, and off by one errors"
[10:01:50] <Jymmm> =)
[10:33:33] <Vq> pcw_home: off by one errors is more common in computer engineering than in computer science though
[10:46:45] <jdh> there are lots of different off-by-ones though
[10:47:38] <Jymmm> jdh: <---- And off by n^3 too ;)
[10:48:34] <archivist> more fun when you didnt know if 10 was hex binary or octal
[10:53:19] <jdh> 0x10, or 010 would remove some ambiguity
[11:37:01] <ssi> so my manual mill has developed a tight spot in the X travel, once per rev
[11:37:21] <ssi> pretty severe one... so much so that you can hear the powerfeed slow down when it hits that spot on every revolution of the screw
[11:37:48] <ssi> is that the ways/gibs? or something with the screw?
[11:38:34] <IchGuckLive> hi all B)
[11:40:36] <IchGuckLive> ssi: what does the dial say in the rev
[11:41:27] <IchGuckLive> <= Today i got lucky owner of a old 32x DVD burner with a open can 500mW diode
[11:42:10] <IchGuckLive> solderd a driver togater and started engraving wood whow what a burn it can go 200mm/min for maybe 5USD parts
[11:42:46] <IchGuckLive> i will test this tomorrw mounted on a DIY so i see how this works out on wood engraving
[12:02:32] <CaptHindsight> http://www.infoworld.com/apple-macintosh-at-30-special-report seems like it was just yesterday
[12:04:16] <CaptHindsight> I remember one reason we kept our PC's was that there wasn't much available for the Mac's for machine and process control
[12:05:32] <CaptHindsight> http://www.infoworld.com/apples-first-macintosh-infoworld-product-of-the-year-winner-11485-234814?source=macintosh_30_index check out some of the PC's especially early laptops in the magazine
[12:07:27] <archivist> ssi, has to be the screw or its bearings
[12:09:47] <CaptHindsight> look at the quality of the drive http://d3nevzfk7ii3be.cloudfront.net/igi/Q1ifW2jIp4glEexo
[12:33:36] <uw> hello

[12:40:07] <IchGuckLive> uw she likes holding here hands like that
[12:41:35] <IchGuckLive> someone knows if there is a spacial piktogramm for carpenter
[12:41:55] <uw> it sure seems it IchGuckLive LOL
[12:42:02] <uw> that or it could be the glue
[12:49:29] <IchGuckLive> someone knows the font linuxcnc ngc is used in
[13:03:15] <CaptHindsight> IchGuckLive: for jpg or bitmaps to something the laser will etch into wood?
[13:04:25] <skunkworks> I miss the computer shopper...
[13:05:08] <IchGuckLive> CaptHindsight: yes it will
[13:37:50] <IchGuckLive> im off BYE
[13:44:10] <tjtr33> i needed to sync some text to some audio ( not karaoke but more bouncing ball for an explanation ).
[13:44:20] <tjtr33> I found something that may be of interest to to docs people.
[13:44:30] <tjtr33> Popcorn.JS is HTML5 ( good for Ubu/Debian/Firefox ) and can sync text to audio, video to video, video to slideshow etc,
[13:44:31] <tjtr33> http://popcornjs.org/ written in JS so I 'spose its OpenSrc
[13:44:58] <tjtr33> nice demo with Linus explaing what an OS is, a video of him synced to a slideshow
[13:54:25] <tjtr33> this is a great demo of the tool explaining early astronomy http://client.heliozilla.com/aer/demo_06.html ( greeks answer how big the sun was and how far away is it )
[13:58:25] <CaptHindsight> I never understood how so much knowledge could be lost or ignored until I witnessed it firsthand here
[14:34:57] <MarkusBec> http://www.youtube.com/watch?v=arjRtCjI9AQ
[14:38:43] <Tom_itx> repost
[14:40:21] <heathmanc> anybody got a minute to step me through how to set up my signal to a vfd using the abs module?
[14:41:22] <heathmanc> i have a 7i48 and have chosen pwm output type 2
[14:41:38] <heathmanc> and have two pins that i have designated cw and ccw
[14:44:18] <Tom_itx> requires 2 pins?
[14:44:43] <Tom_itx> _ cw - ccw
[14:45:06] <heathmanc> it is a wj200 hitachi vfd, it has options for 2 pins
[14:45:16] <heathmanc> so a 0-10 and direction pins
[14:48:04] <heathmanc> and damned if the internet didn't just die and come back
[14:49:18] <heathmanc> i really don't think i have to have the pins for direction
[14:49:27] <heathmanc> I am only going to run it CW
[14:49:50] <heathmanc> but the 7i48 outputs +-10
[14:53:14] <jdh> is there a seperate on/off, or do the direction pins turn it on?
[14:53:56] <heathmanc> dir pins turn it on from what i can tell
[14:54:59] <PCW> you need to add an absolute component
[14:55:35] <heathmanc> That's what I gather
[14:55:52] <PCW> it will take the signed spindle speed, give you absolute spindle speed and a direction bit
[14:57:00] <heathmanc> I am just really unfamiliar with adding the component
[14:58:15] <PCW> You can get the CW and CCW signals from motion
[14:58:48] <heathmanc> I have that all taken care of in pncconf, just have to load the abs module
[14:59:03] <heathmanc> loadrt abs count=1
[14:59:55] <PCW> addf abs.0 servo-thread
[15:01:28] <heathmanc> can that be added postgui?
[15:02:22] <PCW> in main hal file
[15:02:27] <heathmanc> done
[15:04:53] <heathmanc> the pncconf already added this line
[15:04:54] <heathmanc> loadrt abs names=abs.spindle
[15:05:15] <heathmanc> addf abs.spindle servo-thread
[15:05:53] <PCW> related thread on forum:
[15:05:54] <heathmanc> net spindle-vel-cmd => abs.spindle.in
[15:05:55] <PCW> http://www.linuxcnc.org/index.php/english/forum/38-general-linuxcnc-questions/17444-7i33-pwmgenvalue-question
[15:08:19] <heathmanc> from the looks of it, the pncconf already loads the module and removes the sign
[15:10:52] <heathmanc> how is the scale set up? 0-10v for 10v=24k rpm
[15:12:49] <PCW> pwmscale will be 24000 (or -24000) not sure
[15:14:32] <PCW> (assuming the spindle speed is 24000 at 10V)
[15:15:44] <heathmanc> is that value in the .ini?
[15:15:52] <heathmanc> there is an output scale there for 10.0v
[15:17:30] <heathmanc> or setp hm2_5i20.0.pwmgen.02.scale in the hal
[15:17:39] <heathmanc> like the threa
[15:17:40] <heathmanc> d
[15:17:52] <heathmanc> in my calse pwmgen 3 and a 4i65
[15:18:52] <PCW> the setp hm2_5i20.0.pwmgen.02.scale XXX constant can come from the ini file be a literal constant in the hal file, your choice
[15:19:02] <PCW> or be
[15:19:18] <heathmanc> ok, that makes sense
[15:20:59] <ssi> archivist: any idea what could have caused it to suddelny have that problem in the screw? I'm not aware of anything that happened that might have bent the screw or anything
[15:24:12] <heathmanc> appears to work, 10000rpm gets just over 4v on the aout
[15:27:48] <MarkusBec> did anybody used rs485/rs422 over an mesa card?
[15:28:06] <MarkusBec> with a VFD or other stuff
[15:34:00] <heathmanc_> with a vfd
[15:34:30] <MarkusBec> did it work?
[15:50:23] <heathmanc> no, didn't work
[15:50:27] <heathmanc> this vfd realm is new to me
[15:54:09] <heathmanc> have 5v out to the CW pin to the FW pin on the vfd
[15:54:16] <heathmanc> 4v AOUT
[15:54:22] <heathmanc> got to be a vfd setting i am missing
[15:57:44] <MrSunshine> hehe the outsdie of the spindle was not in any way concentric with the spindle shaft :P
[15:58:03] <MrSunshine> oh well, spindle - mrsun 1 - 0 ... tomorrow i will kick its butt!
[16:00:26] <Jymmm> MrSunshine: Why wait when you can just break a chair over it's head instead
[16:01:58] <MrSunshine> cause i needed a ground shaft etc so i went home to think and get stuff, back at it tomorrow =)
[16:41:50] <Deejay> gn8
[17:00:57] <heathmanc> I have had no luck getting this vfd to cooperate
[17:01:48] <heathmanc> I can run it manually no problem
[17:02:55] <heathmanc> very strange thing though, I have only the analog out/gnd and a direction pin hooked up to it, but when I run a program, I immediately get a joint2 following error
[17:06:28] <JT-Shop> I just told the wife we are the proud owners of a bulldozer... she didn't even flinch
[17:06:39] <skunkworks> heh
[17:07:59] <heathmanc> lol
[17:12:02] <JT-Shop> she did ask what I was going to do with it... then offered up my services to the neighbors
[17:18:47] <MarkusBec> heathmanc: you have galvanic isolation
[17:18:56] <MarkusBec> ?
[17:19:14] <heathmanc> should
[17:19:24] <heathmanc> I am just very unfamiliar with this vfd
[17:21:29] <MarkusBec> ah
[17:21:43] <MarkusBec> did you use it as a servo controller
[17:21:48] <MarkusBec> the pwm out ?
[17:22:10] <heathmanc> yes, a 7i48 with a +-10 signal that has had the sign removed
[17:22:32] <heathmanc> i can confirm i get about 5 volts analog out with a 12000 rpm spindle speed command
[17:22:37] <MarkusBec> if you had no encoder on the motor the counter of the controller will not count
[17:23:02] <heathmanc> no encoder on the spindle
[17:23:16] <MarkusBec> i think you have to set it to open loop
[17:23:33] <heathmanc> i don't get an error following error of anything with it
[17:23:41] <WalterN> anyone here use OpenPLM?
[17:23:41] <heathmanc> one of the other axis gives a following error
[17:23:43] <heathmanc> it's strange
[17:23:57] <heathmanc> if i turn off the vfd, the machine operates as normal
[17:24:21] <heathmanc> basically, i'm not sure this is wired up correct
[17:24:34] <MarkusBec> hmm
[17:24:35] <MarkusBec> ok
[17:24:37] <PCW> electrical noise maybe
[17:24:46] <Einar_> I second that!
[17:25:00] <heathmanc> that's what i figure
[17:25:02] <PCW> VFDs are notoriously noisy
[17:25:04] <MarkusBec> did you use shielded cables
[17:25:21] <heathmanc> not at the moment, but it is going to
[17:25:28] <heathmanc> i have it, but was only testing
[17:25:40] <heathmanc> i suppose I will go change it out now
[17:25:53] <PCW> make sure the VFD is grounded well
[17:26:18] <MarkusBec> hm with my vfd the Light of the tubes in the roam with the VFD was modulating with the RPM :)=
[17:26:24] <Einar_> The manual for the drive should outline grounding practice.ood g
[17:26:30] <MarkusBec> cheap china vfd
[17:26:53] <MarkusBec> after it I used shielded cables an a donfoss VFD :)
[17:27:47] <Einar_> Shielded cable may make things worse if you don't ground the shield properly!
[17:27:49] <MarkusBec> heathmanc: maybe you need an aditional Line filter
[17:28:01] <MarkusBec> Einar_: yes
[17:28:15] <MarkusBec> you have to ground it on one side
[17:28:42] <MarkusBec> and only on one side
[17:28:46] <PCW> also to keep ground bumping from VFD to PC to a minimum you might consider a common
[17:28:47] <PCW> mode choke or a couple of 100 Ohm series resistors in the analog out/analog gnd pair going to the VFD
[17:29:38] <PCW> (at the VFD end)
[17:31:00] <Einar_> Use fine stranded wire for ground. Run the grounds to one common point. Don't connect signal ground to a point further from your ground point on a ground carrying noise (in this case the VFD).
[17:31:58] <Einar_> Like my collegue says: "VFD's are our best friends and worst enemies in industry."
[17:32:06] <heathmanc> switched to shielded wire, same result
[17:32:30] <JT-Shop> did you ground the shield?
[17:32:45] <heathmanc> yes, manual says ground it to the same wire as the analog ground
[17:32:47] <heathmanc> only one end
[17:32:56] <heathmanc> on the vfd
[17:33:02] <JT-Shop> ok
[17:33:18] <heathmanc> spindle never makes an attempt to move
[17:33:26] <JT-Shop> if you ground it on both ends you create a current loop
[17:33:28] <MarkusBec> Einar_: RED glowing ground wires :)
[17:33:42] <Einar_> If your machine runs fine when the VFD is not powered up, but faults when spindle is running, you got a noise problem.
[17:33:56] <heathmanc> ok
[17:34:10] <MarkusBec> heathmanc: can you make a picture of your installation
[17:34:18] <heathmanc> vfd runs fine with the machine in manual mode
[17:35:01] <Einar_> Nevermind how the VFD runs. Check that your machine moves as it should with the VFD passive first!
[17:36:15] <PCW> are you saying that this (servo system) runs fine without the VFD on?
[17:36:20] <heathmanc> yes
[17:36:33] <heathmanc> and now i just moved the vfd a little further away, and machine runs fine, but no spindle movement
[17:36:46] <heathmanc> so, that noise issue appears to be resolved
[17:36:53] <heathmanc> had it on the bench testing it out
[17:37:09] <heathmanc> but something is amiss in the config of this vfd
[17:37:28] <heathmanc> should be simple
[17:38:21] <heathmanc> 3 wires going to this thing
[17:38:31] <heathmanc> analog out/gnd and right now just a CW
[17:38:34] <Einar_> A wrong config of VFD should not cause a following error. Maybe if you have spindle feedback, but I think you do not.
[17:38:42] <heathmanc> the following error is resolved
[17:39:18] <heathmanc> it was on the z axis, just related to noise
[17:40:01] <Tom_itx> what max rpm are most of those chinese spindles?
[17:40:05] <Einar_> I usulally run the VFD with a pot and wire jumpers first to check that I got the inputs figured out correctly before I wire it up.
[17:40:08] <Tom_itx> seems most are rather high
[17:42:59] <Einar_> So your problem now is the spindle does not run?
[17:45:46] <heathmanc> right, spindle doesn't run
[17:45:54] <heathmanc> tom, i think they are 24k rpm
[17:46:53] <Tom_itx> i was thinking they were rather high
[17:47:11] <Tom_itx> wonder why they don't have lower rpm higher torque ones
[17:48:14] <heathmanc> have the vfd set for a sourcing input
[17:49:08] <heathmanc> 5vdc from the 7i37com
[17:49:31] <Einar_> What is your A002 parameter?
[17:50:06] <heathmanc> 1
[17:50:42] <Einar_> Then you should be able to run it from the operator panel.
[17:52:59] <Einar_> Sorry. I was to quick. Pg. 3-13 says it is controlled by inputs if A002=1.
[17:53:54] <JT-Shop> PCW, when you have two 7i76 boards do you get 10 stepgens automagicly or do you need to spell it out in the config line?
[17:54:51] <PCW> of not specified at all you will get 10 (most HM2 stuff is like that, all enabled unless specified)
[17:54:58] <PCW> if not
[17:55:34] <PCW> (assuming 7i76x2 5i25/6i25config)
[17:55:56] <Einar_> It seems Pg.4-16 says connecting 1 to P24 should make it run FWD. I'm just skimming the manual quickly here, so may have missed something.
[17:57:16] <JT-Shop> ok thanks
[17:57:34] <Tom_itx> jt, workin on your config?
[17:58:17] <Einar_> Getting late here. I found the manual here if you don't have it: http://www.clrwtr.com/PDF/Hitachi/Hitachi-WJ200-User-Manual.pdf
[18:01:23] <heathmanc> I have the manual, just not having much luck
[18:01:43] <JT-Shop> helping a guy out with 2 7i76 cards
[18:02:13] * JT-Shop is looking for the minimal hal commands to get the pins for the 5i25
[18:02:36] <Einar_> Do as I said: Use jumper wires and a potmeter first to verify that you got your VFD parameters right.
[18:02:45] <heathmanc> is this an issue because it is in sensorless vector mode?
[18:03:05] <micges> JT-Shop: loadrt hostmot2
[18:03:07] <heathmanc> i imagine that isn't right
[18:03:50] <micges> JT-Shop: loadrt hm2_pci config="sserial_port_0=0000xxxx"
[18:04:03] <JT-Shop> thanks
[18:04:03] <micges> JT-Shop: show pin hm2_5i25
[18:06:59] <Einar_> heathmanc: It should still turn if you did not choose the best control algorithm. I would start out with Free V/f first though, and see it running.
[18:07:35] <heathmanc> the autotuning and everything went great, and i have been using this from the operator panel, i will give it a shot
[18:07:57] <Einar_> Did you buy the motor and VFD as a package, these params should areary be optimized.
[18:08:27] <Einar_> OK. Then what you need to do is transfer it from OP to digital inputs.
[18:08:46] <Einar_> And analog speed control.
[18:08:58] <heathmanc> elaborate, the package didn't come together
[18:09:28] <Einar_> Do that with a pot first. The drive will not know the difference between a pot and analog from your controller.
[18:10:04] <heathmanc> right, i just don't have one on hand
[18:10:06] <Einar_> Assuming you use 0-10V speed control.
[18:10:11] <heathmanc> yes, 0-10
[18:10:51] <Einar_> If you have an adjustable bench PSU then use that.
[18:11:05] <PCW> 2 resistors will do for a pot (or tie the input to +10 for full speed)
[18:11:23] <Einar_> Yes.
[18:11:24] <heathmanc> right, just not sure where this is going.. i have verifiable voltage at the input
[18:11:49] <heathmanc> VFD show run, just a whine from the spindle with a 5v input..
[18:11:53] <heathmanc> and no movement
[18:12:54] <Einar_> Is this an async spindle or PM?
[18:13:10] <Einar_> If PM your accel param may be too agressive.
[18:15:01] <Einar_> A pot would give a smooth enough accel whatever your param setting is.
[18:15:38] <heathmanc> 9v battery did nothing
[18:15:54] <heathmanc> the spindle feels sorta stiff when i give it the run/forward input
[18:17:43] <heathmanc> just one setting i don't understand, this A005 setting
[18:17:55] <Einar_> Try setting F002=10.
[18:17:56] <heathmanc> [AT] analog type
[18:18:37] <WalterN> anyone use OpenPLM before?
[18:18:59] <heathmanc> no change
[18:19:42] <heathmanc> lol, so easy before i started to control it with linuxcnc, change the frequency and hit run!
[18:19:51] <jdh> WalterN: I have to use Enovia
[18:20:17] <jdh> I'm sure there are more obtuse and absurd ways of doing things, but I've never seen them.
[18:20:46] <Einar_> Please keep linuxcnc out of the equation until you can control it using jumper wires and preferrably a pot or adjustable PSU.
[18:21:28] <heathmanc> oh, I know it's not me and linuxcnc
[18:21:42] <heathmanc> it's just me
[18:21:48] <WalterN> jdh: never heard of it before, nor have I used any PLM type of software before... as I understand it, they are designed to keep track of drawings and programs and stuff for one specific part?
[18:22:22] <jdh> WalterN: more or less. tracks everything related to a part
[18:22:41] <WalterN> jdh: alright, and thats exactly what I need... (heh)
[18:23:28] <jdh> parts, specs, changes, revs, etc
[18:23:34] <WalterN> yeah
[18:23:54] <WalterN> jdh: know of any good ones besides OpenPLM thats open source?
[18:24:03] <jdh> only one I've ever heard of.
[18:24:21] <jdh> it's not a trivial undertaking and requires robust infrastructure
[18:24:42] <WalterN> what? setting up OpenPLM?
[18:24:57] <jdh> no, writing a PLM package
[18:25:06] <WalterN> oh, yeah... heh
[18:25:16] <jdh> but, you need good DB practices. backups, journaling, etc.
[18:26:45] <WalterN> yeah, at the moment I have a debian minimal install sitting here on a raid1 array doing nothing... I'll figure out backup once I get the PLM software working
[18:27:12] <Einar_> One hour past midnight here. I'll go counting sheeps.
[18:27:37] <heathmanc> I will try to use the hitachi software so I can look at this easier
[18:29:06] <WalterN> bleh
[18:29:16] <WalterN> it seems OpenPLM does not have an IRC channel
[18:29:27] * WalterN rages
[18:29:35] <jdh> ask for a refund
[18:29:57] <WalterN> they want me to sign up or something to download the software
[18:30:14] <WalterN> to the "OpenPLM Professional Network"
[18:30:36] <WalterN> I wonder if its in apt
[18:30:56] <micges> heathmanc: what is your wiring atm between inverter and lcnc?
[18:31:42] <heathmanc> i have a 7i48, with analog out + going to "O", and analog ground to "L"
[18:32:03] <heathmanc> and then I am jumpering the fwd/run at the moment.. P24 to 1
[18:33:02] <micges> do you have 24V logic powered on inv?
[18:33:20] <heathmanc> i am using the 24v from the VFD for logic
[18:33:26] <heathmanc> at the moment
[18:33:41] <heathmanc> once i sort this out, the 7i37 com will provide the fwd/rev inputs
[18:33:56] <micges> ok
[18:34:44] <micges> what pin is have 24V output?
[18:34:53] <heathmanc> P24
[18:35:08] <heathmanc> PLC and L are jumpered for sourcing input
[18:35:33] <micges> ah ok I got it
[18:38:35] <micges> got shortbar between PLC and L pins?
[18:43:46] <micges> ok so you have analog in, and forward
[18:45:02] <micges> isn't needed to be 'start' pin somewhere?
[18:45:25] <WalterN> jdh: ugh... they want me to buy it in order to download the latest version.
[18:45:55] <WalterN> where is the source code? I'll compile it myself
[18:46:18] <heathmanc> yes, shortbar between plc and l
[18:46:24] <heathmanc> analog in and forward
[18:46:58] <micges> ok I don't see any other pin you should connect
[18:47:00] <WalterN> when I click on 'become a professional member' thing, it leads me to a web page that does not exist
[18:47:24] <heathmanc> right, so I assume it's a vfd config problem
[18:51:20] <Tom_itx> http://sourceforge.net/projects/openplm/
[18:51:29] <Tom_itx> what about that?
[18:52:29] <Tom_itx> mmm no files
[18:52:40] <micges> heathmanc: did you double checked initila configuring at page3-5?
[18:55:01] <micges> ah I see you can run it from panel
[18:55:43] <heathmanc> settings match 3-5 default values
[18:56:06] <micges> heathmanc: must be config problem about external controlling or simmilar
[18:56:22] <heathmanc> i will sort it out eventually
[18:56:49] <micges> ok, just tell me A001 param value?
[18:57:12] <Tom_itx> WalterN, http://wiki.openplm.org/trac/browser/main
[18:57:15] <Tom_itx> ?
[18:57:57] <WalterN> Tom_itx: oh, for the source files... it seems like they might have abandoned the website... doing some more searching
[18:58:11] <Tom_itx> http://openplm.org/docs/dev/en/admin/ht_1_install_server.html
[18:58:41] <micges> heathmanc: and param A002
[18:59:36] <Tom_itx> you gotta register to download
[18:59:53] <Tom_itx> http://wiki.openplm.org/trac/register
[19:00:26] <WalterN> yeah I did
[19:01:57] <WalterN> might be good to update my server too... heh
[19:02:06] <Tom_itx> seems opensource that's not so open
[19:02:14] <WalterN> yeah
[19:02:38] <WalterN> "DOWNLOADS_VIEW privileges are required to perform this operation on openPLM-2.0.1.tar.gz"
[19:02:46] <WalterN> when I'm signed in
[19:03:06] <heathmanc> a002 is 1
[19:03:09] <WalterN> evidently they want me to buy something for the latest version
[19:03:35] <WalterN> Tom_itx: http://wiki.openplm.org/trac/discussion/topic/64
[19:04:38] <micges> heathmanc: and A001?
[19:05:01] <heathmanc> a001 is 1
[19:06:24] <Tom_itx> seems like alot of dead ends
[19:06:55] <WalterN> there was a guy in here who uses OpenPLM
[19:06:58] <WalterN> hmm
[19:07:36] <WalterN> it was zultron
[19:07:40] <WalterN> zultron: poke
[19:07:43] <WalterN> :3
[19:09:16] <zee-ipad> hi
[19:10:20] <WalterN> oi
[19:12:03] <zee-ipad> im so confused with the dir+ dir- pul+ pul- wiring on my stepper driver
[19:12:06] <zee-ipad> http://www.automationtechnologiesinc.com/wp-content/uploads/downloads/2012/08/KL-8070D.pdf
[19:13:00] <zee-ipad> on pg 7 in that pdf they clearly show that you need 5v vcc input to dir+ and pul+
[19:13:36] <zee-ipad> http://probotix.com/manuals/PBX-RF_manual.pdf
[19:13:59] <zee-ipad> in my breakout board im not sure where i should be picking up the 5vdc from
[19:14:36] <zee-ipad> im not using the pbx headers but rather using the screw terminals
[19:20:04] <zee-ipad> looks like i need to use the pbx headers to get 5v blah
[21:17:46] <skunkworks> I didn't know alice hill was appointed president of slashdot media... Anyone remember the 'hard edge' column of the computer shopper?
[21:18:53] <eric_unterhausen> computer shopper had a lot of content for what it was
[21:22:12] <skunkworks> killed a lot of tees thoug
[21:22:19] <skunkworks> or treees
[21:22:45] <skunkworks> whatever- trying to type with wet hands
[22:53:58] <archivist> ssi a lock or adjusting nut or grub screw, whatever it needs a bit of investigation
