#emc | Logs for 2009-01-10

[01:00:56] <eric_unterhausen> why did I think that mach3 tool comp was better than emc?
[01:14:17] <biqut2> i got the last of my parts in today and discovered my g540 does not come with a db25 cable so now i have to wait on one of those to come in the mail too :(
[01:14:37] <eric_unterhausen> cables are a scam
[01:16:24] <biqut2> yeah the only place in town with them is a office supply store and they are way over priced so i just ordered one
[01:19:32] <biqut2> i was really looking forward to testing my electronics today and now i will have to wait, but i did order a new 48vdc power supply with my $2 cable
[01:22:58] <eric_unterhausen> are you in the u.s.?
[01:23:15] <SWPadnos> Tennessee, by the look of it
[01:23:38] <SWPadnos> biqut2 (n=biqut2@c-68-52-168-73.hsd1.tn.comcast.net) has joined #emc
[01:23:55] <eric_unterhausen> I had to reboot my comp for some reason, didn't see that
[01:28:28] <SWPadnos> ah, so I see
[01:28:29] <biqut2> yeah in in tennessee
[01:28:40] <biqut2> sorry my wife was distracting me
[01:28:53] <eric_unterhausen> where did you get a 48v power supply?
[01:28:55] <SWPadnos> TMI
[01:30:17] <biqut2> SWPadnos, nothing like that she was just asking me something
[01:30:25] <eric_unterhausen> sure
[01:30:26] <SWPadnos> oh. too bad :)
[01:31:30] <biqut2> http://www.web-tronics.com/3048siouposu.html
[01:31:41] <biqut2> PSU^^^^
[01:32:11] <eric_unterhausen> looks like a switcher?
[01:32:50] <archivist> I run a switcher on my steppers
[01:32:59] <biqut2> yeah, it should work ok
[01:33:22] <eric_unterhausen> archivist: you're special, shouldn't you be asleep?
[01:33:45] <archivist> only 1:33 am
[01:34:12] <archivist> no one to tell me its bed time
[01:34:31] <eric_unterhausen> my wife would be happy if I went to bed that early
[01:37:56] <biqut2> my wife would be happy if i stopped building "things", she has me on a budget now
[01:38:06] <eric_unterhausen> I'm sure everyone will be happy to know that I found my ballscrews
[01:38:45] <eric_unterhausen> I used to have a budget, direct deposit to a checking account
[01:38:59] <eric_unterhausen> kids kinda *****t that up
[01:39:54] <biqut2> lol, well i dont have any kids but i had to strike a deal, paint and remodel for a cnc
[01:40:23] <eric_unterhausen> I'm one lighting fixture in the bathroom behind
[01:42:59] <archivist> ebay browsing time :)
[01:42:59] <archivist> 6.3 amps is abit low
[01:43:24] <eric_unterhausen> I'm looking on ebay too, zero budget pretty much screws up the whole idea though
[01:45:47] <SWPadnos> http://www.antekinc.com/price2.html
[01:46:00] <SWPadnos> PS-3N44 is closest, 300W/44V
[01:46:17] <SWPadnos> the 4N44 is 400W/44V, for $94 (vs. $90 for the 300W)
[01:46:45] <biqut2> archivist, from what i was calculating 6vdc 2.8 amp motors, i figured 48vdc 6.3 amp would be enough??
[01:46:50] <SWPadnos> they sell on eBay as well, though the buy-it-now prices are usually pretty close to their web prices
[01:47:44] <biqut2> * biqut2 doesnt do any business on ebay
[01:48:21] <biqut2> ever since they aquired paypal i quit shopping there
[01:48:21] <SWPadnos> either way. the bulk power supply is more suited for motors, and it's in the same price range as the DC supply you linked to
[01:48:36] <SWPadnos> just pointing it out to the others, since you already have a supply on the way :)
[01:49:01] <biqut2> hhmm, will the one i have on the way work for now or should i send it back??
[01:49:06] <eric_unterhausen> is a 50mm wide linear rail enough to support a pcb router? like this:
[01:49:08] <eric_unterhausen> http://cgi.ebay.com/INA-44-Linear-Rail-2-Wide-Long-Bearing-Guides-KWVE25_W0QQitemZ390022855281QQihZ02
[01:49:21] <SWPadnos> biqut2, it will work, but it's not ideal (theoretically anyway)
[01:49:53] <SWPadnos> the G250 (inside the G540) is essentially a switching power supply
[01:50:20] <SWPadnos> it's best to feed it with something that can handle current spikes easily and often
[01:50:30] <biqut2> SWPadnos, hhmm ok kewl, and thank you for all your input because i have zero experience with steppers and value the help
[01:50:44] <eric_unterhausen> seems like a lot of people put a cap on the output
[01:50:49] <SWPadnos> bulk power supplies can usually go far over their continuous ratings, like double, for short periods
[01:51:32] <SWPadnos> the supply you got will crowbar or go significantly down in voltage if you try to get too much current out of it
[01:51:35] <SWPadnos> sure
[01:52:02] <SWPadnos> also, it may not be able to regulate as well as it should, with a continuously varying load like a choipper drive
[01:52:09] <SWPadnos> -i
[01:53:39] <biqut2> hhmm i figured worst case senario i could just buy one more down the road and run them in parallel
[01:53:48] <SWPadnos> you could do that
[01:54:01] <SWPadnos> it's probably better to use a bulk supply though
[01:54:26] <eric_unterhausen> might not help that much
[01:54:34] <SWPadnos> regulated supplies will also have worse efficiency (probably), so your cabinet will get warm
[01:55:18] <SWPadnos> then again, maybe not. I'm not sure about that
[01:55:23] <biqut2> i planned for ultimate cooling, 10 80mm fans
[01:55:36] <eric_unterhausen> I should put together some unregulated power supplies out of my transformer collection
[01:57:08] <tomp> control signals in shielded cable usually have the shield connected at just one end ( in my experience).
[01:57:09] <tomp> Is there a rule of thumb for which end? ( eg: velocity command to driver )
[01:57:15] <biqut2> eric_unterhausen, put me together a nice big one and i'll send some money your way, im too lazy to build my own cause im really busy at work lately
[01:57:50] <SWPadnos> tomp, ground at the control end, not at the device end
[01:57:57] <tomp> thx
[01:58:01] <SWPadnos> (dunno why, but that's what I've seen)
[01:58:13] <tomp> same here, ran into a weirdo
[01:58:21] <SWPadnos> I resent that!
[01:58:29] <tomp> :)
[01:58:41] <tomp> and i resemble that
[01:58:47] <SWPadnos> * SWPadnos too
[02:13:55] <eric_unterhausen> I wish I knew someone that had a milling machine
[02:14:19] <archivist_ub> get one then you will
[02:14:49] <eric_unterhausen> what good is that?
[02:15:19] <archivist_ub> you can talk to yourself about milling
[02:15:33] <archivist_ub> make sure you listen though
[02:15:35] <eric_unterhausen> that's a great idea
[02:16:10] <eric_unterhausen> how does an MPG have .0001 accuracy? http://cgi.ebay.com/MICRON-ALLEN-BRADLEY-PULSE-GENERATOR-ENCODER-HANDWHEEL_W0QQitemZ260317485157QQihZ016QQcategoryZ55826QQssPageNameZWDVWQQrdZ1QQcmdZViewItem
[02:17:05] <SWPadnos> well it says .0001 right on it
[02:17:24] <eric_unterhausen> how do they make those things click?
[02:17:30] <archivist_ub> a huge amount of people are confused between resolution and accuracy
[02:17:34] <SWPadnos> they' have balls
[02:17:39] <SWPadnos> or something like that
[02:18:05] <eric_unterhausen> they must have balls, but that seems like it would be hard to rig up
[02:18:06] <SWPadnos> well, the seller is just writing what they think the item says
[02:18:19] <SWPadnos> it was from a machine that had tenths jog resolution
[02:18:48] <eric_unterhausen> I'm a little surprised anyone would put that on the hand wheel
[02:18:59] <eric_unterhausen> most things have at least 2 jog speeds
[02:19:04] <SWPadnos> on EMC for sure, since you can use it for a lot of things
[02:20:45] <eric_unterhausen> I have some fairly coarse encoders, but I'd feel strange about using them without detents
[02:23:31] <archivist_ub> archivist_ub is now known as archivist
[02:23:56] <eric_unterhausen> I like this, router auction on ebay with help setting it up on emc2:
[02:23:58] <eric_unterhausen> http://cgi.ebay.com/Sable-2015-CNC-ROUTER-ENGRAVER-mill-PCBs-engraving_W0QQitemZ190277960527QQihZ009QQcategoryZ55826QQssPageNameZWDVWQQrdZ1QQcmdZViewItem
[02:24:48] <SWPadnos> interesting
[04:40:15] <tomp> re: mps resolution of .0001 . written by a salesman. salesmen are stupid. every one salesman requires at least 2 more engineers to make the product do what the saleman said the product would do.
[04:42:15] <tomp> mpGs
[05:05:58] <tomp> re: ebay minimill w/ emc2 advice... i might look up lukechan66 while here, does look intereting, wonder if Taipei/Taiching/Kaoshungg
[05:06:51] <tomp> one is going for 480USD (15800twD) now on a ebay wannabee http://goods.ruten.com.tw/item/qa?11080815592673#detail
[05:09:29] <tomp> http://www.atnet1000.com/ is mfctrs site
[05:22:52] <tomp> oooh, the cnc is offered right next to this cool oldschool tube amp for guitars http://goods.ruten.com.tw/item/show?11071208459288#pic
[05:25:00] <tomp> and the cnc is going for 390 right now, the 480 is the buy it now price
[05:29:48] <DanielFalck> hi tomp
[05:30:01] <DanielFalck> that is a nice retro looking tube amp
[05:31:19] <DanielFalck> tomp: where are you hanging out these days?
[05:44:03] <tomp> Dan i'm in Taichung Taiwan, for at least another month, een here 2
[05:44:21] <tomp> DanielFalck: hiya hiya hiya
[05:50:54] <DanielFalck> tomp: what are you doing there?
[05:51:30] <tomp> http://imagebin.org/35466 http://imagebin.org/35465 http://imagebin.org/35464
[05:51:45] <tomp> 6 custom machines, new control, new generator,
[05:52:01] <DanielFalck> wow
[05:52:11] <DanielFalck> what are you using to control things? emc?
[05:52:29] <tomp> toady saturday, making servo vables up, damn fine pitch 5o pin scsi2 connectors will make me go blind
[05:53:14] <tomp> not emc2, i wish, this is edm. i use MACcnc from INAV in Barcelona
[06:37:55] <eric_unterhausen> I need to move some holes about 4mm
[07:38:16] <tomp> wow, how does this url resolve with '//' in it ? (it works fine) http://www.linuxcnc.org/docview/html//hal_basic_hal.html#r1_1_4
[07:39:09] <eric_unterhausen> double slash is ignored in linux paths, try it type rm -rf //usr/bin or something
[07:39:26] <tomp> wow! your right i just used /////// !
[07:40:08] <eric_unterhausen> makes life easier
[07:40:13] <eric_unterhausen> for script writers
[07:40:52] <tomp> btw: to move the hole, pound a bar into the old hole or thread a bolt into it, then cut new hole
[07:41:15] <tomp> esp if hole is > 4mm
[07:41:30] <eric_unterhausen> yeah, I used to design structural repairs on airplanes
[07:41:42] <eric_unterhausen> we moved holes all the time
[07:42:49] <eric_unterhausen> need some aluminum bar the right size
[07:51:40] <eric_unterhausen> eric_unterhausen is now known as unterhausen
[10:06:33] <JanVanGilsen> Does pyVCP have a hal ready? if i use "loadusr pyvcp -c mypyvcp myfile.xml" the widgets gets created, but the pins aren't ready yet. It might work putting the net commands in the postgui halfile... but i think something like "loadusr -W pyvcp -c graphtest test2.xml" should also work
[10:09:09] <tomp> (i think ) pyVCP wont stop the pins from being created. pycp just uses pins taht exist. your .hal file should create them and connect trhem to threads
[10:10:18] <tomp> after the hal file creates them ( sans any pyvcp directives) you can see if they exist. then continue debugging after pyvcp is loadusr'd.
[10:11:19] <tomp> i mean, create the signals, verify the signals exist, then go onto pyvcp stuff
[10:18:43] <tomp> and i dont know if there is a 'hel_ready', imo that wasnt the problem
[10:18:54] <tomp> hal
[10:24:28] <JanVanGilsen> I think the pins are created when pyvcp_parse loads the xml-file
[10:41:07] <JanVanGilsen> in bin/pyvcp line 77: pycomp.ready()
[10:45:02] <JanVanGilsen> I found the problem
[10:49:24] <JanVanGilsen> the loadusr -W pyvcp command waits until the pyvcp component is ready, but in "loadusr pyvcp -c myvcp myfile.xml" the component myvcp is created, so the pyvcp component doesn't exist and never gets ready.
[10:50:02] <JanVanGilsen> "loadusr -W pyvcp -c pyvcp myfile.xml" does work
[10:50:36] <JanVanGilsen> I'll file in a bug report
[11:36:42] <JanVanGilsen> done :-)
[11:53:51] <tomp> from http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?PyVCP <quote>loadusr -W means it waits until pyvcp is _started_<end quote>
[11:54:32] <tomp> oh, you found that :) too many hours
[11:55:30] <tomp> not a bug
[12:04:48] <tomp> some of the urls on that wiki page are very stale pastebin urls, dont link to temporary pages please, ressurect your images and send to the wiki
[12:05:06] <tomp> stale like over a year old pastebin :)
[12:46:41] <JanVanGilsen> I still think "loadusr -W pyvcp -c mypyvcp myfile.xml" would be the proper way to load a pyvcp in a halfile
[13:30:42] <JanVanGilsen> Got the racks removed from the puma cabinet, it still is pretty heavy but now we got a chance to get it on the first floor =)
[13:38:18] <BigJohnT> cool
[13:43:35] <JanVanGilsen> http://imagebin.org/35476
[13:43:35] <alex_joni> tomp: I agree, especially since pastebin now defaults to 1 month remembering
[13:52:11] <alex_joni> JanVanGilsen: I just closed your bugreport
[13:52:39] <alex_joni> you need to use -Wn mypyvcp for loaduser to wait for the mypyvcp name
[13:52:50] <alex_joni> as described here: http://www.linuxcnc.org/docview/devel/html//hal_basic_hal.html#r1_1_3
[13:53:08] <BigJohnT> :)
[13:53:51] <alex_joni> BigJohnT: thanks for beeing able to link that :D
[14:20:43] <BigJohnT> on the 5i2x what does the "gate" mean? PCI Anything I/O -- 72 I/O bits – 400K gate Spartan 3 FPGA
[14:21:21] <JanVanGilsen> halrun help loadusr doesn't mention the -Wn
[14:22:26] <alex_joni> BigJohnT: that's hard to define
[14:23:14] <BigJohnT> I guess what I'm asking is a 400k gate faster than a 200k gate???
[14:23:23] <BigJohnT> or something like that
[14:24:48] <BigJohnT> JanVanGilsen: it is in man halrun...
[14:26:12] <JanVanGilsen> Mmm, you realy need toknow where to look then ...
[14:31:20] <JanVanGilsen> Maybe changing this on the pyvcp page would help =)
[14:31:40] <BigJohnT> which page is that JanVanGilsen
[14:31:43] <JanVanGilsen> also the html of the new meter is a bit messed up: http://linuxcnc.org/docs/devel/html/hal_pyvcp.html#r1_5_7
[14:32:38] <JanVanGilsen> in 1.2: "halrun -I loadusr pyvcp -c mypanel tiny.xml"
[14:33:11] <JanVanGilsen> maybe better to write: halrun -I loadusr -Wn mypanel pyvcp -c mypanel tiny.xml
[14:34:25] <BigJohnT> I had trouble once with the first one
[14:34:42] <BigJohnT> btw, I've corrected the halrun help loadusr
[14:34:57] <JanVanGilsen> thx
[14:37:33] <BigJohnT> hmmm both seem to work for me
[14:37:48] <BigJohnT> did you have trouble with halrun -I loadusr pyvcp -c mypanel tiny.xml
[14:38:51] <JanVanGilsen> If you tipe it in manualy pins are created b4 you can type in the next net command =)
[14:39:58] <BigJohnT> I'm not sure I understand what you mean... can you expand it a bit?
[14:41:21] <alex_joni> BigJohnT: nope, not faster
[14:41:25] <alex_joni> they are equally fast
[14:41:29] <alex_joni> but you can fit more hardware inside
[14:41:32] <alex_joni> e.g. more stepgens
[14:42:00] <BigJohnT> ok I knew there had to be some improvement in some area :)
[14:42:29] <alex_joni> an FPGA is basicly a chip that contains some basic blocks like or gates and such
[14:42:43] <alex_joni> when you make a hardware design you "tell" it how things get connected
[14:42:59] <BigJohnT> field programmable gate array :)
[14:43:01] <alex_joni> the FPGA as such has all possible connections, you just define which ones are used, and which not
[14:43:04] <alex_joni> indeed
[14:43:23] <BigJohnT> so the 400k has twice as many gates as the 200k
[14:43:36] <alex_joni> right
[14:43:42] <BigJohnT> thanks
[14:43:44] <alex_joni> np
[14:44:27] <alex_joni> BigJohnT: writing loadusr pyvcp in a hal file, without using -W or -Wn won't stop executing the hal file until the component finished loading
[14:44:29] <BigJohnT> I guess that the Spartan 3 is newer than the Spartan II
[14:44:47] <alex_joni> so the execution gets to the next hal command from the hal file, which might connect some pins
[14:44:56] <alex_joni> but those pins might not exist yet, so it will error out
[14:45:16] <alex_joni> using -W or -Wn will basicly halt the halfile execution until the component finished loading and exporting pins
[14:45:24] <alex_joni> then it's safe to do pin linking
[14:45:51] <alex_joni> BigJohnT: in this case spartan 3 vs. 2, I think it's correct, but as a basic rule it's a different product family
[14:46:02] <JanVanGilsen> alex_joni: thx 4 explaining the problem
[14:46:44] <BigJohnT> for the tiny.xml example it would not be needed but for use in a .hal file it is
[14:47:28] <BigJohnT> and I don't see that it is explained properly in the manual
[14:47:49] <BigJohnT> I got it now JanVanGilsen
[14:48:21] <alex_joni> BigJohnT: bug me if it needs more clarification :)
[14:48:42] <BigJohnT> ok
[15:37:33] <tomp> haha an FPGA is a high rise building made of a zillion rooms with no doors nor windows, just 4 walls, ceiling & floor... you have to make connections to make it real building
[15:37:50] <alex_joni> tomp: heh
[15:46:48] <tomp> thats 2 biz in OZ using EMC for retrofits, Aksys PTY and cnce-aus.com
[15:48:39] <tomp> both so new thier webpages are still the unfinished basic format handed out by thier IP
[15:49:20] <tomp> arghm midnite again bye bye
[16:41:09] <jepler> wow. http://www.flickr.com/photos/jeriellsworth/2835524263/
[16:43:39] <alex_joni> jepler: cool.. wonder how big a drawn cpu would be :D
[16:46:59] <JanVanGilsen> We've moved the puma cabinet to the first floor, we did had to strip the whole thing because it's so heavy
[16:47:31] <SWPadnos> JanVanGilsen, your bug report isn['t a bug
[16:47:46] <JanVanGilsen> Yes i realised it :)
[16:47:52] <SWPadnos> you need to use loadusr -Wn
[16:47:53] <SWPadnos> ok :)
[16:48:05] <JanVanGilsen> its a manual issue :D
[16:48:19] <SWPadnos> halcmd -h loadusr
[16:48:22] <SWPadnos> or man halcmd
[16:48:28] <SWPadnos> would tell you the answer ;)
[16:49:00] <JanVanGilsen> i did seek it in "halrun help loadusr"
[16:49:13] <SWPadnos> halrun or halcmd?
[16:49:34] <BigJohnT> SWPadnos: I fixed the lack of -Wn in "halrun help loadusr"
[16:49:37] <JanVanGilsen> BigJohnT updated it already
[16:49:50] <SWPadnos> yep, I saw the commits (thanks)
[16:50:27] <SWPadnos> does halrun actually do anything with "help loadusr" arguments?
[16:50:39] <BigJohnT> yep
[16:50:47] <SWPadnos> oh. cool
[17:29:23] <motioncontrol> good evening
[17:29:32] <motioncontrol> at all
[17:30:09] <motioncontrol> i want speack with jepler for my problex the axis position visualization
[17:31:43] <motioncontrol> jepler is occupated
[17:32:28] <alex_joni> motioncontrol: as a general rule, ask questions in here and if/when people are around to answer them, they will
[17:32:51] <motioncontrol> the problem i have resolv
[17:33:20] <alex_joni> motioncontrol: even writing the explanation here helps, as the channel is logged and indexed by google ;)
[17:34:52] <motioncontrol> ok the information is important.The kernel 2.6.17 with the patch rtai3.5-cv not fuction ok on asus pro5 mother board
[17:35:39] <motioncontrol> i have compile and use rtai with success with 2.6.23 and rtai3.6
[17:36:14] <motioncontrol> i have one question for use the pyvcp is possible help
[17:37:22] <alex_joni> sure, but simply ask your question, don't ask for permissions..
[17:37:39] <motioncontrol> ok thanks
[17:37:57] <motioncontrol> i want personalize the hmi the emc2
[17:39:16] <motioncontrol> i see the pyvcp use , but i don't understad the use the hal command
[17:41:01] <BigJohnT> the latest doc on pyvcp http://www.linuxcnc.org/docs/devel/html/hal_pyvcp.html
[17:41:32] <motioncontrol> i create with gedit one file and save this file in usr directory or in another directory for next step loadusr w namefile pypcv -c namefile.xml?
[17:41:33] <alex_joni> hmm.. BigJohnT beat me to it
[17:41:40] <BigJohnT> and a very basic HAL doc http://www.linuxcnc.org/docs/devel/html/hal_basic_hal.html
[17:42:03] <BigJohnT> alex_joni: :)
[17:42:04] <motioncontrol> ok thanks
[17:42:39] <BigJohnT> usually you put the file in your emc/configs/myconfig directory along with your other config files
[17:42:52] <TomBrown> TomBrown is now known as TomBrown_
[17:42:59] <TomBrown_> TomBrown_ is now known as TomBrown
[17:44:07] <motioncontrol> ok thank.is possible control emc2 with exsternal software,example labview of national Instruments?
[17:44:10] <TomBrown> TomBrown is now known as TomBrown_
[17:44:31] <alex_joni> motioncontrol: theoretically it might be, currently it's not implemented
[17:44:40] <alex_joni> but since it's open source there is nothing that could stop you :)
[17:45:01] <TomBrown_> TomBrown_ is now known as TomBrown
[17:45:45] <motioncontrol> ok.is possible read one library .dll for read and write the pin or the parametar?
[17:46:03] <alex_joni> there is a "library" for python
[17:46:17] <alex_joni> but it certainly not a dll (those are only for windows)
[17:46:50] <TomBrown> Gents, is there any advantage at all to 64 bit emc? As far as I can tell, there is zero advantage so I'm looking at keeping everything 32 bitt, despite having a 64 bit capable system..
[17:47:49] <alex_joni> TomBrown: not that I know of
[17:48:14] <motioncontrol> ok. the emc write data on memory interface , who i can read this data?
[17:48:43] <TomBrown> Thanks Alex.
[17:49:03] <motioncontrol> example the classiladder read pin on hal which?
[17:50:13] <alex_joni> motioncontrol: I didn't understand that
[17:50:47] <motioncontrol> excuse my english
[17:52:37] <alex_joni> motioncontrol: no problem.. just try to explain it differently
[17:54:20] <motioncontrol> the labview on windows can read and write parameter in .dll fuction.In linux is present one equivalent the .dll library.I want use the emc without interface, but i want control the pin with exsternal software, for example labview.You thing is possible?
[17:55:42] <motioncontrol> ofr interface i thing at axis, xemc, mini ecc.
[17:55:53] <alex_joni> theoretically everything is possible (or almost anything)
[17:56:02] <alex_joni> but not necessarely practical to do ..
[17:56:11] <alex_joni> there is a user interface called halui
[17:56:48] <alex_joni> it basicly provides HAL pins for controlling emc2
[17:57:20] <alex_joni> a similar component could be written to be controlled by something else, but I don't know enough about labview to comment
[17:57:57] <motioncontrol> how start the halui?
[17:58:43] <alex_joni> you put HALUI = halui in your ini file in the [HAL] section
[18:00:38] <motioncontrol> ok thanks, i use the virtualmachinewhere on windows and start emulation the linux debian etch with realtime patch, i ceck this command.thanks for all
[18:01:08] <alex_joni> if you use a virtualmachine, then I see no point in using realtime
[18:02:36] <motioncontrol> i have compile the emc2.2.8 whith .config only parameter.i have add patch reatime at the 2.6.20 kernel and fuction low , but good.
[18:02:39] <alex_joni> you can use a regular unpatched linux, and compile emc2 for simulation
[18:03:15] <motioncontrol> yes only simulation i don't have the hardware on my noteboock
[18:03:56] <motioncontrol> i have another machine with mesa m5i20 pci card with analog drives for ceck the realtity sistem
[18:05:16] <alex_joni> ok
[18:05:41] <motioncontrol> thanks for all
[18:31:59] <JymmmEMC> This is so screwed up.... it's now $100 fine for digging thru the recycling bins!
[18:32:08] <JymmmEMC> in the City of SJ
[18:46:52] <jmkasunich> so?
[18:47:17] <jmkasunich> if there was a fine for digging thru trash bins that would be something to complain about
[18:47:24] <jmkasunich> but recycling bins, not so much
[18:47:43] <jmkasunich> the company doing the recycling probably takes a loss on some materials, makes it up on others
[18:48:05] <jmkasunich> if scroungers take all the "hi grade" stuff, the recycling company loses money, and eventually stops recycling
[18:48:50] <jackc> jmkasunich: we have the issue here
[18:49:15] <jackc> the problem is when youre asleep and $randomGuy comes and roots through it, throwing it all around outside nad making a huge noise at 3am
[18:49:47] <jmkasunich> s/guy/crackhead/ probably
[18:50:06] <jackc> ehn i dont judge, not everypoor person is a crackhead
[18:50:11] <jackc> though there is a correlation
[18:50:14] <jmkasunich> true
[18:50:37] <jmkasunich> I guess its better to have them picking from recycle bins than stealing pipes from houses (a problem here)
[18:50:51] <jackc> or ground cables from phone poles, a problem here
[18:51:28] <jmkasunich> even if those who steal cable/pipe aren't crackheads, I _do_ judge them
[18:51:33] <jackc> true that
[18:51:39] <jackc> im not saying theyre good people
[18:51:42] <jmkasunich> that has got to be the least effecient form of theft there is
[18:51:52] <jmkasunich> benefit to thief <<< cost to victim
[18:52:03] <jmkasunich> the difference is just gone
[18:52:23] <jmkasunich> at least if a thief steals $50 cash, the victim only loses $50
[18:52:36] <jmkasunich> a thief stealing $50 in pipe or wire can cost the victim thousands
[18:53:28] <jmkasunich> </rant>
[18:54:11] <jmkasunich> we have some folks here who drive around on trash day and pick up metal, etc
[18:54:16] <JymmmEMC> Well it's the only income for many hungry ppl. and the regulars always clean up after themselves. Just not right imo
[18:54:30] <jmkasunich> I support that, and make a point of setting such stuff out separately
[18:54:32] <jackc> yeah
[18:54:51] <jmkasunich> they don't go thru recycle bins tho (at least I've not seen it), and they don't make a racket at 3am
[18:56:07] <jmkasunich> what it comes down to is character - you can be poor and still be a decent person, or you can be scum at any income level
[19:35:27] <shrdlu-> is the default axis file in the examples folder?
[19:47:07] <shrdlu-> oh, I can just save it. I see
[19:57:33] <skunkworks> heh
[19:57:40] <skunkworks> don't know if this went thru
[19:57:42] <skunkworks> http://imagebin.ca/view/6xBRbgP.html
[19:57:47] <skunkworks> top trace pwm - bottom trace driver enable.
[19:58:44] <jmkasunich> something screwy there
[19:59:06] <jmkasunich> shouldn't they both be the same freq, just different duty cycles?
[20:00:33] <skunkworks> bottom trace - goes low when the current limit it tripped - then at the next rising edge the enable goes back high.
[20:00:47] <skunkworks> *next rising edge of the pwm signal.
[20:01:26] <unterhausen> clean that nasty stuff off your scope
[20:01:46] <skunkworks> hard to tell but the current trips at about 3/4 of the pwm signal.
[20:02:16] <skunkworks> if that makes sense
[20:02:24] <unterhausen> jmkasunich: exactly twice the frequency for some reason?
[20:02:54] <skunkworks> It makes sense to me but that might not mean anything..
[20:02:55] <skunkworks> ;)
[20:03:15] <unterhausen> it's going into current limiting every other cycle?
[20:03:30] <jmkasunich> might be "subharmonic oscillation" - something that happens with current mode control
[20:03:42] <jmkasunich> but usually only when duty cycle exceeds 50%
[20:15:39] <skunkworks> better? http://imagebin.ca/view/M867s6.html ;)
[20:16:22] <alex_joni> the smudge is still there
[20:16:29] <skunkworks> sorry ;)
[20:16:53] <unterhausen> that's not a smudge, it's part of a peanut butter sandwich
[20:17:20] <unterhausen> skunkworks: what did you change?
[20:18:09] <skunkworks> playing around with the current limit pot..
[20:19:06] <JanVanGilsen> http://imagebin.org/35497
[20:19:45] <skunkworks> JanVanGilsen: cool :)
[20:19:51] <JanVanGilsen> the large graph isn't that nice because the print screen function is to slow :p
[20:21:20] <JanVanGilsen> it seems that it builds the image in vertical rows...
[20:21:42] <alex_joni> looks like horizontal to me :)
[20:21:44] <JanVanGilsen> sorry horizontal
[20:22:37] <JanVanGilsen> alex_joni: you corrected me faster then I did myself
[20:23:29] <alex_joni> I'll try to be slower the next time
[20:25:23] <JanVanGilsen> I think the graph-widget is ready for some extensive testing
[20:38:22] <JanVanGilsen> graph.patch: http://pastebin.ca/1305352
[20:38:58] <JanVanGilsen> also includes 2 code changes in the meter widget (cleanup)
[20:40:24] <alex_joni> that's surely a long component :)
[20:40:53] <JanVanGilsen> yeah lotsa scalelines and such =)
[20:42:22] <JanVanGilsen> it was quite short when I started it: http://imagebin.org/34967
[22:22:15] <alex_joni> good night all
