#emc | Logs for 2009-07-23

[03:53:15] <jimbo655> When hooking up an encoder to mov e the XYZ axis what are the pin names for hal?
[03:59:39] <SWPadnos> halcmd show pin will tell you :)
[03:59:55] <SWPadnos> (hint - I think they have the letters "jog" in them)
[04:00:25] <jimbo655> Thanks.... How is your evening?
[04:00:32] <SWPadnos> moderate
[04:00:44] <SWPadnos> at least I fixed the washing machine right
[04:01:39] <Valen> gave her some timtams and a glass of red?
[04:01:41] <Valen> ;->
[04:02:01] <Jymmm> Anyone know of any g-code the really shows off backlash?
[04:02:03] <jimbo655> OK. I called and had the airconditioner fixed..... What fun...
[04:02:06] <il[y]a> SWPadnos: `halcmd show pin' in Terminal?
[04:02:23] <SWPadnos> yes, as long as emc is running
[04:02:49] <SWPadnos> you can even do halcmd show pin "*jog*"
[04:02:57] <il[y]a> SWPadnos: what if it's been --enable-run-in-place ?
[04:03:18] <SWPadnos> then the terminal needs to have had scripts/emc-environment sourced
[04:03:42] <il[y]a> sourced? As added to .bashrc file?
[04:04:06] <SWPadnos> no, you use the source command, or the "." command, which is more or less the same thing
[04:04:17] <SWPadnos> like source scripts/emc-environment
[04:05:41] <il[y]a> so I run `emc2-preparation-H--version1/scripts/emc-environment' before I run `emc2-preparation-H--version1/scripts/emc'?
[04:06:06] <SWPadnos> no
[04:06:09] <SWPadnos> you source it
[04:06:16] <il[y]a> source it?
[04:07:12] <il[y]a> ah! it's a command?!
[04:07:12] <il[y]a> ok, i'll try
[04:07:22] <SWPadnos> yes
[04:07:48] <Jymmm> SWPadnos: Ah, finally used those old explosives to fix the washer?
[04:08:00] <SWPadnos> no. new ones
[04:08:02] <il[y]a> ok
[04:08:46] <il[y]a> SWPadnos: what time is currently there where you are? Morning? Half an hour there were no one in the chat.
[04:09:06] <SWPadnos> it's just past midnight for me
[04:09:48] <jimbo655> SWPadnos: I guess what I am realy looking for is how to define the jog wheel (assign the pins) in 5i20-io.hal?
[04:09:58] <il[y]a> jimbo655: it's writen software compensate that straight forward backlash from rapid movements if hardware was calibrated to do that
[04:10:11] <il[y]a> SWPadnos: ok
[04:15:43] <SWPadnos> jimbo655, I'm nto sure. there's likely an example in a sample config and/or the manual
[04:20:30] <jimbo655> Thanks I will look some more....
[04:20:58] <SWPadnos> I bet "man motion" would tell you some stuff too
[04:21:04] <SWPadnos> time for bed. good night
[04:21:12] <jimbo655> night....
[04:21:43] <il[y]a> jimbo655: http://www.linuxcnc.org/docview/html//man/man9/hm2_pci.9.html

[08:37:28] <Valen1> Valen1 is now known as Valen
[08:43:37] <Valen1> Valen1 is now known as Valen
[10:05:15] <piasdom> g'mornin all
[10:06:03] <Valen> sup
[10:06:12] <Valen> ey, looking to get dad a birthday present
[10:06:19] <Valen> I'm thinking some kind of machining book
[10:06:41] <archivist> heh thats a wide price rage
[10:06:49] <Valen> something with tables for cutting speeds, cutter styles that sort of thing
[10:06:57] <piasdom> the small machinist handbook is great...i still use it
[10:07:40] <piasdom> i have one but been looking for another...just can't find he same one
[10:12:43] <Jymmm> http://new.industrialpress.com/products/category_list/MH
[10:13:10] <Jymmm> It's 'machinery' not 'machinest' handbook =)
[10:13:35] <Jymmm> check amazon too
[10:14:28] <archivist> I think both titles exist (with correct spelling)
[10:14:34] <Jymmm> ah
[10:15:18] <Valen> wikipedia says that both exist
[10:15:25] <Valen> but machinists is now defunct
[10:17:50] <archivist> "Handbook for machine designers and draftsmen"
[10:18:21] <Jymmm> Just get him a make magazine subscription and/or books
[10:18:23] <archivist> F. A. Halsey McGraw-Hill Book Company Inc 1913 signed no 262
[10:18:51] <Jymmm> though I wasn't impressed with the book too much.
[10:19:09] <Valen> he is always complaining about having difficulty getting nice cuts on the lathe
[10:19:15] <archivist> new or old, or what level, pro / amateur
[10:19:31] <Jymmm> get em a new lathe
[10:19:37] <Valen> self taught, probably an advanced amature
[10:19:45] <Valen> the lathe is ok
[10:19:49] <archivist> or good tooling or nice material
[10:20:18] <Valen> he just got a bunch of nice tools, and built himself a new tool post
[10:20:42] <Jymmm> he has a mill too?
[10:20:57] <Valen> but you know if you don't have the right speeds and feeds your not going to get a good finish no matter how good the tools
[10:20:59] <Valen> yeah
[10:21:08] <Valen> its going to be the first thing CnCed
[10:21:19] <Jymmm> he has a cnc ?
[10:21:36] <Valen> both lathe and mill
[10:21:39] <Valen> its getting there
[10:21:46] <Valen> its half CnCed atm
[10:22:03] <Valen> has the linear scales on it, and a running copy of EMC acting as a DRO
[10:22:13] <archivist> Valen, standard black mild steel will give an awful finish but free cutting mild steel will be like butter
[10:22:27] <Valen> he is building the mounts for the motors and ballscrews now
[10:22:42] <Valen> thats the sort of stuff I would like to have in the book ;->
[10:23:05] <Jymmm> machist handbook has that I believe
[10:23:25] <Valen> its near 3000 pages so i'd hope so lol ;->
[10:24:15] <Jymmm> what about cad/cam software?
[10:24:46] <Jymmm> or shiny new servo motors or drivers
[10:24:53] <Jymmm> or mesa card =)
[10:25:28] <Valen> we just got all shiny new stuff lol
[10:25:36] <Valen> 3 mesa cards
[10:25:47] <Valen> 2 servo boards and a 5i23
[10:26:24] <Jymmm> Fine, a refrigerated keg tap for the shop
[10:26:38] <Valen> not a big drinker
[10:26:48] <Jymmm> a hooker?
[10:26:53] <Jymmm> box of cigars?
[10:27:09] <Jymmm> a hooker with a box of cigars?
[10:27:15] <Jymmm> *shrug*
[10:27:15] <Valen> how about a book about machining ?
[10:27:20] <Jymmm> nah
[10:27:24] <Valen> doesn't smoke and his partner is a former model ;-P
[10:28:18] <archivist> Jymmm, is a supplier here is is reply in another place "<Jymmm> ekneuss: mail order brides"
[10:28:36] <archivist> * archivist is a good stirer
[10:29:20] <Jymmm> archivist: you only get 5%
[10:30:01] <archivist> hmm I want the right 5% of said female
[10:39:39] <Jymmm> archivist: quit being so picky... you got an arm and an eyeball last time, just piece em together. Eventually you'll have a whole one.
[10:41:05] <Jymmm> Well 6th order placed. Hopefully this I won't have to return to this vendor.
[10:54:27] <Valen1> Valen1 is now known as Valen
[12:09:07] <Valen1> Valen1 is now known as Valen
[13:13:27] <cradek> ugh, the machine docs say a certain diameter on the pull stud is 17mm +0 -0.011 and the translate that to 0.67 +0 -0.0004
[13:17:43] <cradek> (they)
[13:18:51] <archivist> dorks probably used excel and didnt have enough decimal places showing
[13:23:23] <archivist> measure a sample see if metric or not
[13:33:40] <cradek> BT-40 - definitely the metric is right
[13:33:44] <cradek> (no sample)
[13:48:56] <archivist> http://www.techniksusa.com/wood/psbt.htm
[13:52:04] <archivist> its a google nightmare to find the real spec
[13:53:09] <Valen1> Valen1 is now known as Valen
[14:21:53] <Jymmm> m12 ~= .5" ?
[14:52:00] <Valen1> Valen1 is now known as Valen
[14:55:19] <Valen1> Valen1 is now known as Valen
[15:08:20] <Valen1> Valen1 is now known as Valen
[16:06:13] <geo01005> when selecting a transformer do you use the peak current or the average current?
[16:06:28] <archivist> average
[16:07:02] <geo01005> so if you have a load that is 30 amps, but switched with a 50% duty cycle you only design for 15amps right ?
[16:07:11] <archivist> but it depends on holdup in the psu how close to peak you may wich to get
[16:08:01] <archivist> define 50% eg how long
[16:08:29] <geo01005> say you are switching the load at 10khz with a 50% duty cycle.
[16:09:00] <archivist> then the real average
[16:10:02] <archivist> smoothing caps will be doing a lot of work
[16:10:47] <archivist> at 10khz its not a simple design
[16:10:56] <geo01005> yes, I need lots of them to meet the ripple current.
[16:11:32] <geo01005> I really wish I had an electrical engineering to work with on this project.
[16:12:01] <SWPadnos> note that a transformer rated in VA should be derated by a factor of around 1.8 to get useful DC watts
[16:12:19] <SWPadnos> though you will be able to go much higher for short periods
[16:12:30] <archivist> I did a job where I was given a spec, "12v transformer" so I designed around that, then it arrived, it was a switcher at about 10khz, my diodes nearly melted the solder
[16:12:35] <SWPadnos> also, increasing capacitance will put more stress on the transformer
[16:13:13] <archivist> and peak diode currents during charging will be interesting
[16:13:19] <SWPadnos> yes
[16:13:29] <SWPadnos> especially with too much capacity on the DC side
[16:13:50] <geo01005> sounds like I'm in over my head right?
[16:14:00] <archivist> and the magnetics have fun in those conditions, then overrate somewhat
[16:14:26] <archivist> nah you can do the maths
[16:15:01] <geo01005> I'm having a hard time finding a transformer with the right specifications for this application.
[16:15:19] <archivist> get one wound maybe
[16:15:47] <geo01005> I'm trying to get quotes for one right now.
[16:16:14] <archivist> once upon a time you would be able to find a local transformer and motor winding company
[16:16:54] <archivist> loads shut, we have a few coil winding machines here from a company
[16:17:07] <geo01005> I know of one about an hour away, but they probably want big $$$
[16:17:56] <SWPadnos> where does the 10 kHz spec come from? (is this for a motor power supply?)
[16:18:16] <geo01005> SWPadnos, this is for an EDM like power supply.
[16:18:30] <geo01005> might go up to 100 khz.
[16:18:43] <archivist> what voltage
[16:18:56] <geo01005> 70-100VDC
[16:19:04] <SWPadnos> are you trying to find an input transformer (from AC mains to power your unit), or something within the supply for the step-up function?
[16:19:09] <geo01005> hopefully lower frequency work though.
[16:19:13] <archivist> and whos limiting peak current
[16:19:24] <geo01005> power resistors.
[16:19:30] <SWPadnos> nasty
[16:19:47] <geo01005> this is for AC mains to the 70-100VDC.
[16:20:11] <SWPadnos> what kind of current in each pulse?
[16:20:27] <geo01005> old school EDM power supply, only like %25-30 efficient.
[16:20:30] <SWPadnos> actually, that won't matter much to the transformer - those current spikes will be fed from the DC caps
[16:20:33] <archivist> almost a straight off line switcher
[16:20:52] <geo01005> yeah, but the peak current will be between 10-60 amps.
[16:21:09] <geo01005> I'm going to do some experimental designs to get the right parameters.
[16:21:13] <Jymmm> geo01005 you need a custom xfmr?
[16:21:30] <geo01005> Jymmm, I might :)
[16:21:37] <Jymmm> qty?
[16:21:40] <geo01005> 1
[16:21:42] <SWPadnos> you choose the transformer for average power, and choose the caps for peak current (and voltage of course)
[16:21:45] <Jymmm> han on
[16:22:35] <Jymmm> geo01005 location?
[16:22:40] <geo01005> So I was looking at using a transformer designed for 480 on the primary and 120 on the secondary, to 4:1 winding ratio.
[16:22:42] <geo01005> Utah.
[16:22:59] <geo01005> Then use that transformer to go from my 208 to 52 volts.
[16:23:20] <Jymmm> sucks to be you... but http://www.mcitransformer.com/ They will wind custom ransformers, one off's too
[16:23:30] <geo01005> Then rectified that would give around 70 volts.
[16:24:09] <geo01005> But the transformer would have to be rated like 4 time the KVA under those conditions.
[16:24:40] <geo01005> thanks for the link Jymmm, I'll check them out.
[16:24:51] <Jymmm> they're nice ppl too
[16:26:32] <geo01005> I hoped to find a used xfmr....
[16:28:26] <SWPadnos> you should only search locally. a transformer big enough for you will weigh 75-125 pounds
[16:29:05] <geo01005> Yes, I know they will be large and expensive to ship.
[16:29:21] <cradek> beware the power rating decreases proportionally if you run at a lower input voltage
[16:30:08] <SWPadnos> and double-check your real power requirements. I'd be surprised if you really need 60A average at 100V
[16:30:47] <geo01005> No, I suspect that is will only be about 30 amps max average current.
[16:30:51] <cradek> wow, for what?
[16:30:59] <SWPadnos> EDM supply
[16:31:03] <cradek> ah
[16:31:22] <geo01005> lighting up LEDs ;)
[16:34:12] <archivist> lighting LED's is a lot different to EDM
[16:34:42] <geo01005> well it is sort of a light emitting capacitor right :)
[16:34:54] <geo01005> light = failed capacitor.
[16:36:49] <archivist> arc lamp
[16:41:52] <antichip> lol metal vapor arc lamp. cool
[16:48:20] <jimbo655> Is there a sample *io.hal file that shows the setup for a jog wheel?
[16:51:07] <SWPadnos> a quick search of the wiki yields this: http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?JogWheel
[16:52:42] <geo01005> so the power rating of a xfmr is based first on resistive heating and second on magnetic saturation right?
[16:52:50] <SWPadnos> no
[16:53:00] <SWPadnos> it's based on whatever the manufacturer rated it on
[16:53:15] <jimbo655> Thanks
[16:53:29] <archivist> some push the saturation a bit
[16:53:42] <SWPadnos> you need a certain amount of mass per watt, so a 2 kVA transformer will be about the same size regardless of the ratio or voltage ratings
[16:53:48] <archivist> specially the cheaper stuff
[16:55:29] <archivist> some design the magnetic saturation to provide current limiting
[16:56:02] <geo01005> I'm trying to justify using a 480-120 transformer on 208 to get 52 vac.
[16:57:03] <archivist> remember the tx is not designed for the greater current in that case
[16:57:23] <geo01005> I guess I haven't read enough about transformer to figure that out.
[16:57:24] <archivist> it wont have the right copper
[16:57:35] <SWPadnos> right - it needs to be derated linearly with respect to the primary voltage
[16:57:47] <geo01005> linearly huh?
[16:57:48] <SWPadnos> (so you'll get 208/480 * the kVA rating otu of it)
[16:57:51] <SWPadnos> yes
[16:58:07] <geo01005> I was thinking squared because the resistive losses
[16:58:09] <SWPadnos> then derate again since you're using it in a DC application, this time by a factor of 1.8
[16:58:11] <SWPadnos> no
[16:58:16] <archivist> its designed at a certain ampere turns
[16:58:17] <geo01005> power=i^2*r
[16:58:27] <SWPadnos> you're using the same current in the secondary
[16:58:37] <SWPadnos> that's why you derate linearly
[16:58:39] <geo01005> ahh, I see.
[16:58:57] <SWPadnos> a 408:240 transformer rated at 2400 vA essentially has a 10A output
[16:59:26] <SWPadnos> if you use it at 204 (as a 204:120), it's still 10A, so it's 1200 vA
[16:59:30] <SWPadnos> or you melt the wire
[17:01:01] <geo01005> I suppose I should say that I was going to use a three phase xfrm, so another 1.73 for that right?
[17:01:18] <SWPadnos> I don't think so
[17:01:38] <SWPadnos> they all feed the same DC bus, so you get full power out of it
[17:01:40] <geo01005> hmm, that is what all the selection guides say...
[17:01:48] <archivist> a 3 phase is really 3 singles
[17:01:50] <SWPadnos> unless you only connect one phase to a bridge rectifier
[17:02:21] <geo01005> like on this page: http://www.electricalpowertransformer.com/acme-transformer-selection.html
[17:02:36] <geo01005> down in the three phase section.
[17:04:34] <geo01005> "(1) To determine three phase KVA when volts and ampers are known:
[17:04:36] <geo01005> Three Phase KVA =Volts x Amps x 1.73 /1000"
[17:05:42] <SWPadnos> you don't have a 3-phase load with known volts and amps
[17:05:53] <Valen1> Valen1 is now known as Valen
[17:05:54] <SWPadnos> you have a 1-phase load with more or less known volts and amps
[17:06:02] <geo01005> ahh, I see that.
[17:06:27] <archivist> you can 3 phase rectify
[17:06:51] <archivist> to single dc
[17:07:01] <ilya_> So, have someone tried to compile in simulation mode on 9.04 as in the `Installing EMC2'?
[17:07:08] <geo01005> so say 73 volts DC at 30 average amps = 2200 VA
[17:07:49] <geo01005> 2200*(480/208)*1.8=9100 VA
[17:08:09] <geo01005> so a 10KVA xfmr is a minimum.
[17:09:54] <SWPadnos> ilya_, yes, I have compiled on 9.04. I don't remember how though :)
[17:11:48] <ilya_> SWPadnos: interesting if 5.5 of `Installing EMC' is OK. I'm on a GPRS again and can't even set up the networking without the wvdial program.
[17:16:53] <Valen> Probably easiest to not bother with a "transformer" for that kind of thing
[17:17:04] <Valen> look inside a PC power supply for a base idea.
[17:17:23] <Valen> rectify your incoming AC (put a power factor correcting first stage on it)
[17:17:57] <Valen> then run that through a step down style transformer
[17:18:21] <Valen> but you run that at 10+khz (at those power levels try to keep it at 26 or so khz)
[17:18:28] <Valen> (otherwise it'll whine like a bitch)
[17:19:02] <Valen> and you wind up with a power transformer that's about the size of a pack of cards that'll do what you want
[17:19:12] <Valen> its still really not trivial but still
[17:19:29] <Valen> for "testing" I'd be tempted to do a "badboy" style power supply
[17:20:01] <Valen> rectify incoming mains, then a straight buck regulator (a diode bridge, a buttload of caps and a mosfet basically)
[17:21:45] <Valen> but all that is a project in itself
[17:21:56] <geo01005> Valen, I had a speced a switching power supply to begin with, but where the switching frequency of the power supply was on the same order of the switching of the load it cause some problems.
[17:22:43] <geo01005> Ideally I would just use a switching supply set up so that it acts like a constant current supply and forget the power resistors for current limiting.
[17:22:44] <Valen> integrate the two
[17:23:00] <Valen> what actual output waveform are you after?
[17:23:32] <geo01005> are you familiar with EDM power supplies?
[17:23:36] <Valen> nope
[17:24:26] <geo01005> this is a good intro: http://www.make-it-better.us/article.cfm?articleID=35
[17:26:02] <skunkworks_> http://www.electronicsam.com/images/KandT/conversion/diodes.JPG
[17:26:09] <skunkworks_> My diodes ;)
[17:27:23] <geo01005> I'm going for the 1970-1985 style generator : http://www.make-it-better.us/images/articles/35_history_3.jpg
[17:27:57] <Valen> nothing too fancy
[17:28:07] <Valen> hmmm
[17:28:24] <Valen> Heres a thought, nfi if it'd work
[17:28:35] <Valen> put a coil across your part
[17:28:44] <Valen> (transformer style)
[17:29:24] <Valen> ramp some current through the primary then stop it suddenly
[17:29:29] <Valen> think car ignition coil
[17:29:46] <Valen> no capacitor needed, the energy storage is in your primary coil
[17:29:49] <geo01005> yeah, there are a few patents with a generator like that.
[17:29:51] <Valen> you have your isolation
[17:30:03] <Valen> typical ;->
[17:31:15] <Valen> if its not for profit you can still do it
[17:31:33] <skunkworks_> this is awesome.. http://www.astromart.com/news/news.asp?news_id=967
[17:31:46] <skunkworks_> ^but the moon landing was fake! ;)
[17:33:08] <pjm> u can see where the LRO is : http://lroc.sese.asu.edu/whereislro/
[17:33:12] <pjm> fake!!!
[17:33:36] <pjm> i expect the loonies will be saying NASA has photoshopped the LRO images to add in the apollo stuff
[17:34:07] <geo01005> Valen, I know that there are some better generator topologies out there for EDM, but I not actually using it for EDM.
[17:34:21] <Valen> so what are you trying to do?
[17:34:33] <geo01005> So, for now, I'm sticking to the old school stuff.
[17:35:07] <geo01005> I would need to you sign an NDA to tell you, sorry :(
[17:35:59] <Valen> I'd also have to be awake
[17:36:06] <Valen> both are unlikley ;->
[17:45:58] <ilya_> So, will the `linux-rt' metapackage add all necessary kernel modules to compile emc2_2.3.1?
[17:50:45] <SWPadnos> no. linux-rt has nothing to do with EMC2 or RTAI
[17:52:30] <ilya_> SWPadnos: then which RTAI modules
[17:52:38] <ilya_> in linux ubuntu
[17:52:57] <SWPadnos> the ones from linuxcnc.org
[17:53:11] <SWPadnos> unless you want to compile RTAI for yourself, and then compile EMC2
[17:53:42] <ilya_> SWPadnos: the ones from stock repositories for ubuntu 9.04
[17:53:52] <ilya_> without compiling RTAI
[17:54:15] <SWPadnos> is there an RTAI in the stock repositories for 9.04?
[17:54:23] <SWPadnos> RTAI and -rt are *not* the same thing
[17:55:11] <ilya_> oh :(
[17:55:37] <ilya_> so, i will have to compile RTAI in this case
[17:56:04] <SWPadnos> yes
[19:06:28] <antichip> I'm having an issue where I have no working cd burner or cd's, plenty of CF cards and usb memsticks though, any suggestions?
[19:10:52] <archivist_attic> antichip, look in the email archive and on the wiki, someond did experiment with a usb stick
[19:11:52] <SWPadnos> antichip, do you have access to a machine with Ubuntu 8.10 or 9.04? (even from a LiveCD)
[19:13:43] <SWPadnos> if so, you can download the EMC2 ISO to that machine, and use the application under System->Preferences (I think - could be Administration) that makes bootable USB sticks
[19:14:15] <SWPadnos> you point it at an ISO file, and it makes the stick bootable, complete with persistent file system
[19:14:29] <SWPadnos> (using the ISO you told it to use)
[19:16:41] <skunkworks_> really?
[19:16:43] <skunkworks_> neat
[19:17:19] <BJT-Work> cool
[19:19:09] <SWPadnos> yep
[19:19:30] <SWPadnos> I think it might not have worked quite right in 8.10, but it works great in 9.04
[19:20:08] <BJT-Work> does it work on 8.04?
[19:20:22] <SWPadnos> I don't know if there's a package for 8.04
[19:20:28] <BJT-Work> ok
[19:20:37] <SWPadnos> it's just an application though, so no reason why it couldn't work
[19:20:46] <SWPadnos> you can create an 8.04 disc, of course
[19:20:55] <SWPadnos> err - an 8.04 USB stick
[19:25:40] <ilya_> usb-creator from 9.04 when it creates 8.04's bootable usb disk, changes 8.04 so it mounts any usb flash disk as a CD-ROM and it actually "Can not be mounted"
[19:25:59] <ilya_> use usb-creator for 8.10 or 9.04 vrsions only
[19:26:24] <ilya_> and, RTAI-kernel, can not mount usb devices by default
[19:26:56] <ilya_> although, there is a trick in wiki.linuxcnc.org
[19:39:42] <ilya_> back-port for 8.04, usb-creator, and pythin-central-0.6.7 upgrade
[19:58:03] <antichip> I will look into that later tonight.
[19:58:11] <antichip> thank-you
[21:53:31] <DaViruz> i just busted a perfectly good 750W ac servo out of pure stupidity :(
[21:54:26] <DaViruz> hit the wrog button with it laying on my work bench, and the damn thing spins out of control and hits the floor
[21:54:48] <DaViruz> still works but makes a horrible noise..
[21:55:47] <archivist> may just need bearings fixing/replacing
[21:56:00] <DaViruz> yea, seems to be the front bearing that's busted
[21:57:20] <DaViruz> didn't seem to be anything that held the end plates positively located against the center part, i hope it won't be terribly misaligned when i put it back together again..
[21:59:02] <DaViruz> the darndest thing, the front bearing seemd a bit loose in the front plate.. i couldn't feel any play, but the outer race rotated freely..
[21:59:42] <DaViruz> there's a clamp plate that prevents it from doing so when in operation, but still seems a bit odd
[22:39:58] <jimbo655> Looking at the jog wheel wiki.. They have used added buttons for axis selection and resolution selection. Is it possable to use the axis and resolution in the interface to do this part and just have a jog wheel or do I have to implement there whole interface?
[22:44:27] <Guest413> anyone home?
[22:44:37] <Guest413> Guest413 is now known as Trab9000
[22:44:38] <Trab9000> hi

[22:45:28] <archivist> well past work time
[22:45:29] <Trab9000> anyway, I'm looking for some help.
[22:45:43] <Trab9000> oh, well sorry ot hear that.
[22:45:48] <Trab9000> err to
[22:50:00] <Guest413> opps
[22:50:20] <Guest413> Guest413 is now known as Somethingotherth
[22:50:41] <Somethingotherth> guess they didn't like my nick
[22:50:48] <Somethingotherth> Somethingotherth is now known as Trab9001
[22:51:08] <Trab9001> anyhow.
[22:51:41] <archivist> your nick is not your connection problem
[22:52:06] <Trab9001> i got it.
[22:52:14] <Trab9001> cable sucks in my town lately
[22:52:40] <Trab9001> hopefully I can hold a connection for a bit and maybe get some insight.
