#emc | Logs for 2010-01-18

[00:41:33] <Dave911> Jymmm: OK I went over the wall and downloaded some windows software that can image ext4 Linux drives. I had the Windoze box hardware setup available so that is what I did. The software I used is called R-Drive Image 4.6 and it is free for 15 days. It works very much like Acronis. I may have to buy a copy if this works out ok as Acronis seems to be getting bad. It is just about done...
[00:41:35] <Dave911> ...cloning this one ext4 drive. It is not nearly as fast as Acronis but it seems to be getting the job done.
[00:42:27] <Jymmm> Dave911: I don't promote M$ utilities/apps unless exceptional.
[00:44:35] <Dave911> I'm not promoting it, just saying that it looks like it works .... ext4 seems to be very new. I would have installed ext3 had I realized that and avoided this hassle.
[00:50:16] <Dave911> Also, Partimage doesn't support ext4. When I did a search for "image ext4", the recommendations were Clonezilla. Oh well....
[01:04:46] <MarkusBec> MarkusBec is now known as MarkusBec_away
[01:07:55] <Jymmm> EXT3/4 are JFS
[01:10:35] <tom3p> components get added to threads in the order of appearance in the hal file. and if there are multiple hal files, is the rule 1st unsorted file, first component thru last listed.... till 2nd unsorted file, first component thru last listed... nth hal file , 1st thru last listed?
[01:25:14] <tom3p> wow, ^^^ >unless< over-ridden by a specific priority (eg addf mycomp.myfunc 1 ocurring in the 4th of 33 hal files )

[02:51:35] <danimal_garage> sweet, machine is done. all i need is a little static phase converter for my coolant pump
[02:51:36] <danimal_garage> got all the wiring cleaned up and organized
[02:56:07] <eric_unterhausen> a vfd might be cheaper for a small motor
[02:58:17] <danimal_garage> i was just gunna build a phase converter
[02:59:04] <eric_unterhausen> I have 2 I'd give you, but your weather is too nice and so I can't
[02:59:11] <danimal_garage> haha
[02:59:18] <danimal_garage> newman!
[02:59:23] <eric_unterhausen> if you lived in Wisconsin, no problem
[03:00:07] <danimal_garage> well then i'd have great cheese and Johnsonville bratts
[03:00:20] <danimal_garage> so you'd still be a hater
[03:00:27] <danimal_garage> :)
[03:00:29] <cradek> done?? I'm not familiar with this word... what does it mean?
[03:00:35] <danimal_garage> haha
[03:00:44] <eric_unterhausen> srlsy
[03:00:46] <danimal_garage> well i guess it isnt done
[03:01:02] <danimal_garage> i just realized i would like a real button for my collet
[03:01:11] <eric_unterhausen> I forget about phase converters, do they have to match the amps?
[03:02:45] <danimal_garage> using the mouse to hit the button on the screen sucks
[03:02:45] <cradek> yep
[03:02:45] <danimal_garage> static phase converters need to fall within a certain range
[03:05:52] <cradek> using the mouse for anything sucks
[03:05:52] <danimal_garage> is it easy to link an f key to a pyvcp button?
[03:11:53] <cradek> no, I think it's impossible
[03:11:53] <danimal_garage> first time i've heard that with emc
[03:11:53] <cradek> wellll I'm pretty sure you can't do it in the vcp language
[03:11:53] <cradek> I think AXIS has control of the keyboard
[03:11:53] <danimal_garage> can you make an f key a hal pin?
[03:11:53] <cradek> I bet a toggle with center off, momentary both ways, is what you want
[03:11:53] <cradek> I like those - I use them for jogging on the mill
[03:11:53] <cradek> no AXIS can't do that either (without modification)
[03:11:53] <danimal_garage> that or just a momentary button
[03:11:53] <danimal_garage> i just have one button for open/close in pypyvcp
[03:11:53] <danimal_garage> however it would be nice to have a momentary button for close
[03:11:53] <danimal_garage> for open*
[03:11:53] <tom3p> is the wiki down? i'm waiting 5min now for the upload page to appear
[03:11:53] <danimal_garage> the main page works
[03:11:53] <danimal_garage> however if i click any of the links, it does take a while
[03:11:53] <danimal_garage> hasnt opened a page yet
[03:11:53] <danimal_garage> i'd like the collet open valve to be momentary
[03:11:53] <danimal_garage> no need for it to stay on and leak air
[03:11:53] <tom3p> lucky that the wiki editor is open on client side, i copy the work to local editor till wiki feels better
[03:13:33] <tom3p> danimal_garage: do you have a way to sense that its open and closed ( air on till open , air on till closed )
[03:13:55] <tom3p> 2 proxes maybe
[03:14:11] <danimal_garage> i got some pressure sensors
[03:14:17] <danimal_garage> air pressure sensors
[03:21:10] <ChanServ> [#emc] "This is the #emc channel - talk related to the Enhanced Machine Controller and general machining. Website: http://www.linuxcnc.org/, wiki at http://wiki.linuxcnc.org/"
[03:22:04] <tom3p> 2 solenoids? use a 3way, one side always closing it, the other to the switch which overides and opens it.
[03:22:31] <tom3p> or doe sit leak both ways?
[03:22:48] <danimal_garage> yea, i suppose i could get rid of the collet close pin and just hardwire it. and i can have an output coming off that switch, going to an input on the mesa to release the open button
[03:23:05] <danimal_garage> leaks both ways
[03:23:14] <danimal_garage> 2 3 ways i believe
[03:23:20] <danimal_garage> it's not a 4 way
[03:23:35] <danimal_garage> should be easy now that i think of it
[03:23:39] <tom3p> clamps should default to clamped . leaks is bad. doe sit trap air ( need to vent?)
[03:23:56] <tom3p> does it (dangit)
[03:24:23] <danimal_garage> it has 2 little vent holes in the closer that leak
[03:25:16] <tom3p> meant to blow chips out of the way? or just designed to annoy you?
[03:25:58] <danimal_garage> i believe it's designed to piss me off
[03:26:08] <danimal_garage> says so in the manual
[03:26:25] <danimal_garage> "piss Dan off------ chapter 11"
[03:29:50] <danimal_garage> i'm uploading pictures now
[03:36:16] <dan1mal> http://smg.photobucket.com/albums/v20/danielwilcox/hardinge/
[03:36:26] <dan1mal> there's some pictures of the lathe
[03:36:44] <dan1mal> still got a couple things i want to do to it, but it's runable
[03:42:11] <dan1mal> learned alot on this project, which is good. i have a few things in store for the mill now.
[03:42:31] <tom3p> danimal_garage: remember how the 3R stuff had vents that cleaned bores and surfaces before clamping?
[03:43:13] <dan1mal> no, we just used their smaller stuff
[03:43:27] <dan1mal> but i know what you mean
[03:44:06] <dan1mal> i had that in mind for my mill's pallet system
[03:44:58] <tom3p> very nice machine!
[03:45:06] <dan1mal> thanks!
[03:45:10] <tom3p> you got neat toys
[03:45:30] <dan1mal> i try :)
[03:46:51] <dan1mal> took me about 2 months to complete
[03:47:09] <dan1mal> granted i didnt work on it for some weeks
[03:47:17] <cradek> are the amps in the right box?
[03:47:50] <dan1mal> nope, they're in a box on the upper left side
[03:48:02] <dan1mal> you can see it in the last picture
[03:48:10] <dan1mal> last 2 pictures
[03:48:12] <cradek> oh ok, cool!
[03:48:15] <dan1mal> has a fan in it
[03:48:33] <dan1mal> thanks!
[03:48:58] <cradek> where's your part chute?
[03:49:08] <dan1mal> the right cabinet just has my vfd, fuses, and soon to be the phase converter for the coolant pump
[03:49:12] <dan1mal> took it off
[03:49:17] <dan1mal> wont be needing it
[03:49:29] <cradek> oh right, you use a 3 jaw
[03:49:42] <dan1mal> i'll be using fixtures mostly
[03:50:04] <dan1mal> i have my own products, and thats all i really make, so not much changes with what'll be run it it
[03:50:04] <cradek> looks different with the covers on - some day I oughta finish mine!
[03:50:14] <dan1mal> ha
[03:50:15] <ries> any python knowledgeable guy/girl here I can ask a small question?
[03:51:20] <dan1mal> i want to get some terminals for the 50 pin connectors, so i can just run them through the side of the enclosure
[03:51:29] <dan1mal> and quickly disconnect the pc as needed
[03:53:22] <dan1mal> still gotta put a mouse tray on it too, but i might just get a touch pad like my mill has
[03:53:36] <dan1mal> right now i just use my knee :)
[04:01:23] <jfigie> Another machine comes to life: http://www.machineability.com/Bridgeport_series_II.html
[04:03:09] <dan1mal> damn, that makes mine look like crap lol
[04:03:15] <dan1mal> nice work
[04:03:16] <cradek> wow! it has resolvers and you swiped the part of the old control that decodes them? that's slick.
[04:04:09] <jfigie> I think they are encoders but they have 125 cycles per rev sine outputs
[04:04:30] <cradek> I love the sign above the monitor!
[04:04:32] <dan1mal> it's impressive
[04:04:56] <jfigie> I did the sign for you guys that did all the work on AXIS
[04:05:17] <cradek> it looks like a video game panel - so cool.
[04:06:42] <dan1mal> i wouldnt kick it out of bed for eating cookies
[04:07:40] <jfigie> cradek: FYI if you want to see what I did to get the keyboard inputs to increase or decrease the jog speed check out the bridgeport_postgui.hal
[04:08:53] <dan1mal> how long did that take you?
[04:09:12] <jfigie> The JogSpeed signal is what I wanted to initialize
[04:09:31] <jfigie> I have been working on it for about 1 year. But not full time
[04:09:43] <jfigie> Too many other more important things
[04:10:42] <dan1mal> yea looks like you put some time into it
[04:12:50] <dan1mal> must be nice having a big enclosure like that to work with
[04:13:11] <dan1mal> everything can fit in there
[04:13:52] <jfigie> I had to move one xformer out to another smaller cabinet on the back
[04:14:20] <dan1mal> still
[04:14:24] <jfigie> In hind sight I don't think putting the mother bd in the cabinet was the best
[04:14:32] <dan1mal> no?
[04:14:34] <jfigie> It is really hard to get to it
[04:14:39] <dan1mal> oh
[04:14:42] <dan1mal> yea
[04:14:49] <jfigie> I am also concerned about heat and vibration
[04:14:59] <dan1mal> i thought about mounting mine to the door of my cabinet
[04:15:05] <jfigie> the Hard drive is mounted on an isolator
[04:15:16] <dan1mal> but the disk drives would be a PITA
[04:15:32] <jfigie> right now it gets to about 80 degrees without the machine working hard
[04:15:50] <jfigie> but I can cut a hole in the door to let cool air in
[04:16:10] <dan1mal> can always put in a fan too
[04:16:12] <jfigie> PITA?
[04:16:17] <dan1mal> pain in the ass
[04:17:44] <dan1mal> i dont have much room for the cd rom
[04:18:03] <dan1mal> however i guess i could leave it out
[04:18:15] <dan1mal> i cant remember the last time i used it on my mill
[04:18:22] <dan1mal> just plug it in when i need it
[04:18:27] <dan1mal> hmm
[05:04:42] <celeron55_> i've made some progress with this http://code.google.com/p/jukumagic/
[05:05:23] <celeron55_> in addition to some menu thinkering etc i was asked to add g-code exporting... http://jukumagic.googlecode.com/svn/wiki/gcode_export_in_heekscad.png
[05:05:39] <celeron55_> that's the result loaded into heekscad 8)
[05:06:24] <celeron55_> now if someone could actually try doing something with that, it'd be nice
[05:22:05] <danimal_garage> like what?
[05:51:22] <tom3p> is that picture of motion needed to make a stripboard?
[05:57:50] <tom3p> jfigle: very nice machine ( hmm gone already)
[06:03:02] <tom3p> celeron55_: may be of use, source code included http://3dreplicators.com/New%20Front%20Page/Documentation/Tools/Stripboard%20designer.htm
[06:03:15] <danimal_garage> is there any easy way to go from a 50 pin ribbon cable to a d sub connector??
[06:03:32] <danimal_garage> without having to solder 50 pins x3
[06:04:15] <eric_unterhausen> get a scsi cable after searching for hours at a surplus house
[06:08:02] <danimal_garage> do they have adapters to go to a 50 pin ribbon?
[06:08:20] <eric_unterhausen> I have some for motherboards
[06:08:50] <eric_unterhausen> actually, I think I got mine out of old hard drive enclosures
[06:09:30] <danimal_garage> i just want to avoid soldering 150 connections at all costs
[06:09:38] <danimal_garage> actually it'd be more like 300
[06:09:44] <danimal_garage> since i gotta do both ends
[06:09:55] <eric_unterhausen> what cable in between?
[06:10:37] <danimal_garage> whatever, i'd just like to use a regular cable between the machine and the computer instead of ribbon cables
[06:13:39] <danimal_garage> did you see my machine pics?
[06:13:42] <danimal_garage> http://smg.photobucket.com/albums/v20/danielwilcox/hardinge/
[06:13:49] <danimal_garage> it's up and running
[06:15:14] <danimal_garage> is there any way to add a debounce to a ladder?
[06:17:06] <danimal_garage> or do you just use a timer?
[06:21:11] <tom3p> danimal_garage: maybe useful http://www.winfordeng.com/products/cat_brk.php
[06:22:11] <eric_unterhausen> I don't see what a breakout board is going to do for him or I would have mentioned it
[06:23:13] <danimal_garage> still a bit of work involved
[06:23:28] <tom3p> 2 breakout = 50pin ide to db50 adapter
[06:23:35] <tom3p> yeah
[06:23:44] <danimal_garage> i think this will cost me probably 75-$100 to do
[06:23:54] <danimal_garage> at least to do it easily
[06:24:16] <tom3p> for the debounce, handy if you know the circuit chips they're emulating in ladder http://www.cybermike.net/reference/liec_book/Digital/DIGI_10.html
[06:25:32] <danimal_garage> now that i think about it, they have scsi to 50 pin ribbon adapters, but i tihnk they're $20 plus each one
[06:25:47] <danimal_garage> thanks tom3p, i bookmarked that, looks like a handy page
[06:26:02] <danimal_garage> especially for a n00b like me
[06:27:56] <danimal_garage> i need a debounce before my tool changed output coil in ladder
[06:59:16] <EbiDK> EbiDK is now known as EbiDK|AWAY
[07:33:56] <kloeri_> hi cradek
[07:39:46] <Jymmm> cradek: That should help the joins for a bit.
[07:40:16] <cradek> can't load freenode's blog page right now... must be a lot of this.
[07:40:32] <cradek> I was trying to figure out the difference between +r and +R
[07:40:34] <Jymmm> cradek: Botnet attcks
[07:40:40] <cradek> yeah
[07:40:41] <lilalinux_away> lilalinux_away is now known as lilalinux
[07:41:09] <Jymmm> Oh, one is a ban, the other is a mute, both have error messages explainsing to the perosn they need to be registered
[07:41:19] <cradek> kloeri_: hi
[07:41:30] <kloeri_> cradek: +R only allows identified people to talk and +r only allows identified people to join the channel
[07:41:58] <cradek> kloeri_: thanks
[07:42:03] <kloeri_> and my mentioning the blog in a global notice earlier might have affected the server hosting it slightly negatively :)
[07:42:28] <cradek> do they get around the +R with the CTCP VERSION query?
[07:42:44] <kloeri_> no
[07:43:00] <cradek> oh I see, you set +R for us afterward.
[07:43:15] <cradek> thanks (we so rarely have trouble...)
[07:43:16] <kloeri_> +R prevents the spam so all you see from the spam bots are the joins and parting
[07:43:22] <cradek> gotcha
[07:44:43] <Jymmm> +r (block unidentified) This mode prevents users who are not identified with NickServ from joining the channel. Users will receive a server notice explaining this if they try to join.
[07:44:47] <cradek> looks like we may still have one remaining: slcvyuho
[07:44:59] <Jymmm> Jymmm has kicked slcvyuho from #emc
[07:45:11] <Jymmm> +R (quiet unidentified) This mode prevents users who are not identified with NickServ from speaking in the channel. Users will receive a server notice explaining this if they try to speak.
[07:49:11] <Jymmm> Heh, nice lil botnet they have going there.
[07:56:13] <cradek> <!-- This object plays the "hey everybody, I'm watching gay porno!" sound -->
[07:56:23] <cradek> that's sure mature
[07:56:45] <Jymmm> cradek: ?
[07:57:07] <cradek> in their js
[07:57:11] <Jymmm> Ah, heh
[07:57:30] <cradek> document.write(unescape("%3Cscript src='" + gaJsHost + "google-analytics.com/ga.js' type='text/javascript'%3E%3C/script%3E"));
[07:57:59] <cradek> is this the point of it all?
[07:58:46] <Jymmm> Oh I suspect it's just the appitiser
[08:01:15] <lilalinux> lilalinux is now known as lilalinux_away
[08:02:28] <Jymmm> lets see if we're still in the line of fire
[08:14:49] <cradek> goodnight Jymmm
[08:15:01] <Jymmm> cradek: G'night =)
[08:50:24] <lilalinux_away> lilalinux_away is now known as lilalinux
[09:28:10] <celeron55> tom3p: yes, the toolpath in the picture does make the stripboard layout out of raw circuit board material. That's what i was asked to do. :P
[09:28:38] <MarkusBec_away> MarkusBec_away is now known as MarkusBec
[09:30:09] <christel> [Global Notice] Hi all, just a quick heads up that the js spam is still at large, and we encourage you to NOT click any untrusted URLs as the attack will start a HTTP POST connection using your ip to spam further, this could result in a network ban for you. The blog has more information. Please be careful and show some consideration for your fellow ircers! Thank you.

[10:22:53] <piasdom> g'morning all
[11:02:38] <Valen> ey got my dual core atom running
[11:02:41] <Valen> latency of 970 ;->
[11:02:53] <Valen> thats a 30 second run but still
[11:03:07] <Valen> no openGL stuff running yet, need to turn the 3d on
[11:11:16] <Valen> had spam issues have we?
[11:16:32] <micges_work> Valen: yes
[11:17:03] <Valen> looks like they are using it as a base or some such still
[11:34:03] <christel> [Global Notice] Hi all, we're noticing that a lot of clients are flooding off due to autoresponding to repeated version requests, you may wish to set your client NOT to send replies as these replies are not rate limited. As an example; '/set -clear ctcp_version_response or /ignore *!*@* CTCPS' should work in Irssi. For any assistance please visit us in #freenode. Thanks
[11:36:33] <christel> [Global Notice] Duh! Apologies, that should be /set -clear ctcp_reply or /ignore *!*@* CTCPS for Irssi. -- These notices will continue during the attacks, as they are our only way of communicating with the user base, we understand its annoying to some and if you are bothered by them, feel free to '/ignore *!*@freenode/staff/* notice'
[11:46:08] <archivist_emc> this excess flood quit from phreak and krushia are a sign I believe, seeing that in a lot of channels
[11:46:37] <krushia> its ctcp flooding
[11:47:32] <Valen> turn ctcp replies off then?
[11:47:44] <krushia> just did
[11:47:56] <krushia> sucks... i use ctcp a lot
[11:48:01] <Valen> what for?
[11:48:16] <krushia> i run a couple irc b0ts
[11:48:22] <Valen> I see
[11:48:30] <krushia> and at a minimum i need to open dcc
[11:48:59] <krushia> seems konversation has no ctcp response throttling option
[11:49:12] <Valen> ahh sucks
[11:49:32] <Valen> archivist_emc: see my message about that dual atom board?
[11:49:42] <archivist_emc> yes :)
[11:50:42] <Valen> thats pretty nifty for < $200
[11:51:04] <Valen> thats with 2GB of ram and a 250Gb hdd
[11:51:58] <archivist_emc> plug a usb thingy in while the test is running would be interesting
[11:52:07] <Valen> why's that?
[11:52:19] <Valen> I'll need to turn 3D on too, I cant run axis yet
[11:52:23] <Valen> last time that was a bitch
[11:54:11] <Valen> (just wondering why specifically the USB thingie)
[11:54:46] <archivist_emc> I was reading the usb spec again this weekend
[11:56:22] <Valen> mmm?
[11:57:28] <Valen> sounds like a plesant past time ;-P
[11:59:14] <archivist_emc> isochronous pipes :)
[12:02:42] <Valen> I C
[12:02:46] <Valen> well bed time for me
[12:02:47] <Valen> nighty night
[13:00:57] <jthornton> * jthornton wonders if I need to use TTL mode or RS-422 mode on my 7i33?
[15:01:31] <Jymmm> jthornton: to/from what?
[15:01:53] <JT-Work> Jymmm: my encoders on the Hardinge lathe
[15:02:29] <Jymmm> I'd suspect TTL, but that's just a guess.
[15:02:50] <JT-Work> I know just jam the wires and they will sort it out LOL
[15:03:06] <Jymmm> lol, sorta kinda =)
[15:25:20] <cradek> JT-Work: does the encoder have +A -A +B -B +Z -Z?
[15:26:36] <JT-Work> yes
[15:26:53] <cradek> then definitely use rs422 mode
[15:28:15] <JT-Work> cradek: thanks
[15:29:07] <JT-Work> is TTL for when you only have a single signal like plus only?
[15:29:19] <Jymmm> jthornton: See, I TOLD you to use RS-422 and not TTL!
[15:29:23] <cradek> JT-Work: yes
[15:29:29] <JT-Work> thanks
[15:30:04] <cradek> JT-Work: because there's less noise immunity with a single signal, the mesa board does a lot of filtering when you put it in TTL mode. this gives you a much lower top counting speed.
[15:30:17] <JT-Work> thanks
[15:33:12] <Jymmm> cradek: Heh, I had to read what you said about the mesa three times to "oh, I get what he's saying now" =)
[15:34:33] <cradek> was it unclear or was it just you?
[15:35:23] <Jymmm> cradek: You had explained what and why in a single statement
[15:35:30] <Jymmm> jsut took me a bit
[15:36:35] <dan1mal> morning
[15:39:29] <skunkworks_> http://www.electronicsam.com/images/KandT/conversion/zaxis/gears1.JPG
[15:39:36] <skunkworks_> little differnt angle ;)
[15:40:54] <dan1mal> so where was the washer?
[15:41:23] <skunkworks_> http://www.electronicsam.com/images/KandT/conversion/zaxis/gears.JPG
[15:41:35] <skunkworks_> between the 2 lower gears (small ones).
[15:42:07] <dan1mal> ok that makes sense.
[15:42:08] <skunkworks_> it is funny - took grinding off .04 to get rid of .0005 backlash.
[15:42:12] <skunkworks_> :)
[15:42:18] <dan1mal> wow
[15:42:38] <skunkworks_> but that one washer is taking out the slack of 5 gears.
[15:43:24] <dan1mal> well the angle isnt too extreme on the helix
[15:43:47] <skunkworks_> exaclty
[15:44:34] <dan1mal> what's the lead on your ballscrew?
[15:44:43] <dan1mal> .200"/rev?
[15:46:51] <skunkworks_> 3 rev per inch
[15:48:09] <dan1mal> thats more than half a degree of rotational slop you had
[15:49:00] <dan1mal> if you know the angle of the helix on the gears, you could actually calculate how much you had to remove from the washer
[15:50:10] <skunkworks_> yes. (we didn't) ;)
[15:50:51] <skunkworks_> that gear is about a foot into the machine - and only access is though a 4"x4" holes
[15:51:40] <dan1mal> youch
[15:51:46] <Jymmm> skunkworks_: and the problem is?
[15:52:27] <skunkworks_> no problem. Thank you sir! Can I have some more!
[15:52:54] <Jymmm> skunkworks_: Sure, just take the cat of nine tails off the wall and have at it!
[15:53:49] <dan1mal> sme lathe pictures: http://smg.photobucket.com/albums/v20/danielwilcox/hardinge/
[15:55:00] <skunkworks_> the adjustment was never made. The washer had the original grinding marks on it - and a serial number on both sides. so that is about 40 years of wear. give or take
[15:55:14] <dan1mal> wow
[15:55:47] <skunkworks_> the maitenence department these came out of only had a hammer and chisle for tools.
[15:55:51] <skunkworks_> we figure.
[15:55:54] <dan1mal> no serial number on there anymore :)
[15:56:23] <dan1mal> most just use duct tape
[15:59:10] <skunkworks_> dan1mal: very nice!
[15:59:23] <dan1mal> thanks!
[15:59:57] <dan1mal> it's pretty much up and running, i just need some sort of static phase converter for my coolant pump
[16:03:03] <dan1mal> i also want to put a fan in the enclosure where the vfd is
[16:22:32] <tom3p> re: index only homing. one description described it as 'move to a scribed line and then home'
[16:22:32] <tom3p> so, if i had a vernier of 20" length, then i might jog to 15.6" and home AND get a dialog asking the value?
[16:22:32] <tom3p> that'd be like heidenhain's Distance Coded Scales that have Z phase indexes every cm.
[16:22:32] <tom3p> Those scales also have a coarse position encoded on an extra track.
[16:22:32] <tom3p> Merely crossing 2 Z marks tells the homing operation where home is.
[16:28:24] <cradek> tom3p: the idea is you the user know how to place the axis between two particular indexes. so you do that, then when you tell emc to home, it does the index search only, and you're homed
[16:28:35] <tom3p> cool
[16:29:14] <JT-Work> dan1mal: cool
[16:29:58] <JT-Work> dan1mal: can you just use a starting circuit with some run caps on your coolant pump?
[16:30:42] <danimal_garage> thanks!
[16:30:56] <danimal_garage> i think thats what cradek uses
[16:31:24] <danimal_garage> gotta figure out the run caps though
[16:31:56] <danimal_garage> i found somethnig that says 70uf per HP
[16:31:59] <skunkworks_> I would think a inexpensive vfd.. It can't be that many hp..
[16:32:02] <danimal_garage> does that sound about right?
[16:32:11] <danimal_garage> 1/6 hp
[16:32:32] <cradek> I don't recommend what I did. It has trouble starting when it's cold.
[16:32:46] <danimal_garage> how cold?
[16:33:43] <danimal_garage> doesnt get much below 60 here
[16:36:09] <danimal_garage> i guess i can do a vfd
[16:37:08] <JT-Work> I think it is 75-100 for the start caps and the run caps whatever it takes to balance the voltage
[16:37:29] <cradek> my shop gets down to 45
[16:37:41] <cradek> soybean oil is kind of thick at 45
[16:37:49] <danimal_garage> youch 45 is cold
[16:38:58] <JT-Work> for $125 you can get a drive GS1-21P0 from Automation Direct
[16:39:09] <JT-Work> 1hp
[16:39:29] <JT-Work> http://www.automationdirect.com/adc/Shopping/Catalog/Drives/GS1_%28120_-z-_230_VAC_V-z-Hz_Control%29/GS1_Drive_Units_%28120_-z-_230_VAC%29/GS1-21P0
[16:39:49] <JT-Work> I'm glad when my shop gets up to 45F
[16:40:15] <cradek> 45 is the lowest setting on the thermostat...
[16:40:36] <cradek> keeps the coolant from freezing and also seems to prevent condensation
[16:40:44] <danimal_garage> lol
[16:40:55] <danimal_garage> i dont have heat in my garage
[16:41:22] <danimal_garage> i have attic vents so all the heat would go right out anyways
[16:41:54] <danimal_garage> the guy i bought my 2 vfd's from had some smaller ones... i'm gunna see what he wants for them
[16:42:32] <danimal_garage> he's local too
[16:42:52] <danimal_garage> i got my big ones for $50 each, so i bet i can get the smaller ones for cheaper
[16:45:32] <danimal_garage> eh he's got one for $65, a 1.5hp version
[16:46:21] <danimal_garage> dammit it's a 380-460v
[16:50:44] <danimal_garage> yess he's got another one for $45
[16:50:59] <danimal_garage> and it's the right voltage
[17:02:21] <micges_> hello all
[17:02:21] <danimal_garage> damn the manual doesnt say if it can run from single phase
[17:02:21] <danimal_garage> hi micges_
[17:13:05] <lilalinux> lilalinux is now known as lilalinux_away
[17:13:12] <lilalinux_away> lilalinux_away is now known as lilalinux
[17:25:17] <lilalinux> lilalinux is now known as lilalinux_away
[17:52:19] <JT-Work> danimal_garage: I ran some 3ph in 3ph out Toshiba's years ago controlling a magnet on a vibratory feeder
[17:53:14] <danimal_garage> cradek: do you happen to know the ratio between hi and low gears on the hnc: my eyeball tach saysabout 3.75:1, how far off am i? i dont have an encoder yet
[17:53:25] <danimal_garage> cool, and it worked?
[17:53:32] <danimal_garage> hmm
[17:54:45] <danimal_garage> i have a fried york vfd, i should try and fix it to see if that'll wwork
[18:05:56] <danimal_garage> hmmm doesnt look like my old vfd is friend afterall
[18:06:36] <danimal_garage> it was giving me hardware faults before, but i took it apart and blew all the chips out of it and i no longer get the fault
[18:11:50] <JT-Work> yea, the feeders were made in Germany and set up for 50Hz and would not feed with 60Hz LOL
[18:12:04] <danimal_garage> ha weird
[18:12:12] <JT-Work> so we plunked a vfd in there to tune the feeder
[18:12:20] <JT-Work> brb
[18:16:18] <danimal_garage> hey it works!
[18:16:29] <danimal_garage> runs off of single phase just fine
[18:16:51] <danimal_garage> cool, i love it when i can use the stuff i have
[19:13:51] <Guest239> Test
[19:30:56] <JT-Work> it didn't work
[19:36:40] <danimal_garage> the vfd did :)
[19:36:47] <JT-Work> cool
[19:37:15] <danimal_garage> little overkill, it's a 2.2kw drive, and only a .16kw motor
[19:37:34] <danimal_garage> but i have it already, so it's free
[19:37:42] <JT-Work> free is the best kind
[19:39:06] <danimal_garage> yep
[20:40:14] <lilalinux_away> lilalinux_away is now known as lilalinux
[20:47:54] <bucky> heya Jymmm
[20:57:18] <bassogigas> is it safe and useful to upgrade from 2.2.5 to 2.3.x?
[21:00:32] <micges> make backup of your configs before upgrade, and you can always back to 2.2.5 if you want
[21:00:43] <micges> then it will be safe
[21:03:40] <Casainho> Hello :-)
[21:04:15] <Casainho> Does anyone tested the trick: "Height probing for PCB isolation routing"? :: http://phk.freebsd.dk/CncPcb/
[21:38:58] <andypugh> Does anyone know a UK source of machinable graphite rod? (Cheaper than Goodfellow, that is)
[21:40:29] <archivist_emc> the graphite rods for nuclear bombs co ltd back of the chinese take away selafield
[21:41:35] <archivist_emc> dunno if carbolite still exists
[21:42:22] <andypugh> As furnace maker yes.
[21:42:57] <andypugh> Ah well, it was a query from a friend. I already found them Goodfellow (£377 for a 12" x 1" rod) and Erodex.
[21:43:46] <archivist_emc> iirc carbolite used to make stuff like that too
[21:43:54] <archivist_emc> hence the name
[21:44:45] <archivist_emc> their 26ft bed lathe was rescued and is now in a museum, was a fun job :)
[21:47:46] <GonMD> i *hate* surfacing an MDF table. would prolly help if my shop vac would actually retain everything in took in.
[21:56:17] <LawrenceG> GonMD, you can build a sacrificial table addition like I use for PCBs. It used mdf blocks to get the right height and then a top peice of lexan which I surfaced and then drilled/tapped a 1" grid of 10-24 holes
[21:56:43] <LawrenceG> GonMD, http://members.shaw.ca/swstuff/spindle-encoder.html second picture shows the table addition
[21:57:21] <GonMD> oh, very cool.
[21:57:36] <LawrenceG> cheap and easy
[21:58:04] <GonMD> ill give that a shot.
[21:58:35] <LawrenceG> I used contact cement to hold the mdf and lexan together
[22:06:31] <GonMD> i must say. if MDF dust were white, my garage would look awfully suspicious
[22:11:42] <Dave911> Trying to get EMC2 running on an Atom 330 Mitx intel board with Karmin 9.10 SMP and a custom kernel compile.
[22:11:44] <Dave911> I'm very close, but I ran into a snag.
[22:11:45] <Dave911> For some reason it appears that when I load a EMC config that uses the stepgen and Parport, EMC2 attempts to load the RTAI Parport module, then I get an error saying that the resource is already taken, which of course it was since it was already recognized by Linux when the OS was first loaded. It seems like EMC2 should unload the original Parport module and then load the RTAI realtime...
[22:11:47] <Dave911> ...Parport module but that isn't happening and I have no idea as to why. A very similar Linux configuration works fine in a Uniprocessor setup. So ?? I'm not sure what to do next.
[22:11:48] <Dave911> Here is the output of the dmesg http://pastebin.com/m1c626371
[22:11:50] <Dave911> Any ideas? FWIW, I'm writing all of this up so I can put it into the Wiki and avoid some future pain..
[22:12:05] <Dave911> I meant Karmic ..:-)
[22:12:29] <andypugh> Which EMC?
[22:12:38] <Dave911> 2.3.4
[22:13:28] <andypugh> I think you need Parport_PC modularised rather than installed
[22:14:07] <andypugh> I get a related problem that I need to install a module before 2.4 will run.
[22:14:23] <Dave911> So you think that in the kernel compile config it somehow got checked as a non-module
[22:14:46] <andypugh> Possibly.
[22:14:54] <andypugh> does lsmod list it?
[22:15:07] <Dave911> Let me check.. brb
[22:16:06] <phreak> archivist_emc: what is this flood of which you speak?
[22:16:54] <archivist_emc> phreak, did you see any notices from freenode
[22:17:14] <phreak> ...
[22:17:18] <Dave911> Yes, it is listed as "parport" and it is being used by partport_pc
[22:17:27] <archivist_emc> phreak, [Global Notice] Hi all, we're noticing that a lot of clients are flooding off due to autoresponding to repeated version requests, you may wish to set your client NOT to send replies as these replies are not rate limited. As an example; '/set -clear ctcp_version_response or /ignore *!*@* CTCPS' should work in Irssi. For any assistance please visit us in #freenode. Thanks
[22:18:16] <Dave911> gosh typos... being used by parport_pc
[22:18:36] <phreak> looking now
[22:18:59] <Dave911> The actual EMC2 rev is from a tarball off of source forge labeled 2.3.4-1
[22:19:10] <andypugh> it's "parport" you need unloaded.
[22:19:19] <phreak> no such
[22:19:46] <archivist_emc> phreak, you were off and on for a while also [Global Notice] Duh! Apologies, that should be /set -clear ctcp_reply or /ignore *!*@* CTCPS for Irssi
[22:20:11] <phreak> i have konversation
[22:20:15] <Dave911> that's what I was thinking... The same EMC2 version with the same kernel but in a uniprocessor setup doesn't have this issue..
[22:21:52] <andypugh> I admit to being a Linux noob, but I have the issue where I need to insmod parport to run 2.4
[22:22:13] <Dave911> both ParPort and ParPort_pc are seen as modules
[22:22:25] <andypugh> so you could try rmmod parport (or parport_pc) and then try emc again
[22:23:13] <phreak> archivist_emc: I put something in the config, dunno if it helps any
[22:23:34] <Dave911> >>I have the issue where I need to insmod parport to run 2.4
[22:23:36] <Dave911> Interesting .... ok well I was wondering about that .... I'll try unloading parport and then run emc2, I may try unloading both ... brb
[22:25:39] <archivist_emc> phreak, was only for about 10 minutes today
[22:30:47] <Dave911> andypugh: That works.. I had to remove 3 programs that were depending on the parport module, ppdev, lp, and parport_pc
[22:30:49] <Dave911> I wonder what the heck ppdev does?? perhaps that is a module that emc is not expecting to be there so it gives up? sound like a development module potentially.
[22:31:14] <andypugh> What do you have in the /etc/modules file?
[22:31:18] <Dave911> programs ..--> modules
[22:31:34] <Valen> ppdev is not in 9.10's apt-cache search
[22:36:37] <Dave911> I need to backup here a bit ... these modules are swapped out on the fly obviously as needed.. and ppdev is being loaded by the os on startup as it is tied to the parport module...
[22:36:39] <Dave911> soo.... I don't understand what you mean Valen.
[22:37:15] <Valen> just saying ppdev isnt a package and isn't mentioned by any packages
[22:37:50] <Dave911> Let me look at that again.. I appreciate you looking..
[22:38:11] <Valen> its probably a kernel module or something like you say
[22:38:24] <Valen> if you want to stop it from loading I believe you can blacklist modules
[22:39:41] <Dave911> Yep, I bet I checked something that was experimental in the kernel compile config and that got sucked in....perhaps ??
[22:39:59] <Dave911> it was definitely "ppdev"
[22:40:31] <Valen> its probably just loading up to manage the hardware for a printer or something
[22:41:22] <Dave911> Would something like that be in the kernel compile config ??
[22:41:40] <Valen> no, you could remove support for it but blacklisting is probably easier
[22:42:00] <Valen> if everything works when you rmmod
[22:42:25] <Valen> http://www.cyberciti.biz/tips/avoid-linux-kernel-module-driver-autoloading.html
[22:44:43] <Dave911> Yep, worked fine when I rmmod'ed three modules ... ok
[22:44:45] <Dave911> Cool, I'll find the hangup and blacklist the module if I can't figure out how it got there!
[22:44:47] <Dave911> Valen: Thanks!
[22:44:48] <Dave911> andypugh: Thanks! I'll report back.. :-)
[22:45:03] <Valen> have the fun
[22:48:04] <Valen> oh hey Dave911 did you get one of those dual core atom boards?
[23:01:33] <jt-plasma> wow I actually got three wires connected on the hardinge
[23:09:35] <ds3> for the US folks, does anyone have recommendations on 220V power connectors for bench top 220V machineary? somehow I don't think the 2 standard flat blades used for 115V is a good idea to use at 220V
[23:10:26] <andypugh> Why not? The current is lower...
[23:11:02] <ds3> potential for confusion
[23:11:16] <andypugh> I like these a lot: http://www.neutrik.com/us/en/industry/204_390365502/powerCON_20_Amp_productlist.aspx
[23:11:23] <Dave911> The best are the 3 prong twist lock plugs for us 220 VAC single phase.. the cheapie solution are the 2 flat prongs and the one ground prong. I don't remember the nema numbers
[23:11:24] <ds3> that'd mean I have the exact same out with 220V as a 110V outlet and it sounds like a plan for disaster
[23:11:48] <ds3> L6-20 and L6-15 are the twist locks rated at 220V
[23:12:10] <Dave911> Don't do that... my Dad saved money doing that and plugged a shop vac into the circuit! It went really fast for a few minutes and then ......puff..
[23:12:18] <ds3> are the flat prongs parallel just like the stock 110 ones?
[23:12:43] <Dave911> They are twisted 90 degrees
[23:12:58] <ds3> andypugh: those look specialized
[23:13:05] <andypugh> IEC 60309?
[23:13:09] <andypugh> http://en.wikipedia.org/wiki/IEC_309
[23:13:27] <ds3> andypugh: right... the L6-15 and L6-20's do that: http://www.nooutage.com/nema_configurations.htm
[23:13:31] <Dave911> Actually 220 volt 3 prong twist locks are not bad $ wise
[23:14:16] <andypugh> PoweCON are surprisingly cheap, assuming you can get them in the US
[23:14:47] <ds3> problem there is my 110:220 xformer has a 2 round hole european plug but the machinery (chinese import) has 3-4 different connectors on it and the just supplied poorly fitting adapters :( feels like a fire hazard to me
[23:15:14] <andypugh> Yes, PowerCON is available in the US.
[23:15:15] <andypugh> http://www.markertek.com/Cables-Connectors-Adapters/Power-Connectors-Adapters/Neutrik-USA-Inc/NAC3FCA.xhtml
[23:15:18] <Dave911> I meant the 6-15R is the cheapie.. Note that the R stands for receptacle and a P means plug..
[23:15:27] <ds3> andypugh: what industry uses them? I have see the L6-xx's in telco and in NOC's a lot
[23:15:40] <andypugh> PowerCON is broadcast PA et
[23:15:54] <ds3> ah...
[23:16:20] <andypugh> They do a very similar loudspeaker connector with 4 poles, I am using those for 3-phase motors and they are popular for Steppers too.
[23:16:30] <ds3> I'd check mcmaster but mcmaster's site don't like my browser on hand :(
[23:17:23] <Dave911> You can buy the 220 volt flat plugs and recpts and the twist locks at Home Depot, Lowes etc, assuming that you are in the US ds3? I know Andy is over the pond..
[23:17:58] <ds3> Dave911: yes, I am in the US... I am trying to avoid them for cost reasons... I priced them out for an overhead power drop and they were $$$$$
[23:18:00] <andypugh> I really like them, they go in and twist to latch in a very satisfying way. The contacts are long pins mating with lots of plated fingers, and they don't make contact until latched. All in all rather nice, especially for the price.
[23:18:40] <ds3> what about the 2 pin european connectors?
[23:18:43] <andypugh> Under $10 for a plug-socket combo
[23:18:52] <ds3> andypugh: at Lowes?!
[23:19:08] <andypugh> I meant PowerCON, at the URL I posted above
[23:19:18] <ds3> Oh
[23:19:46] <andypugh> You could use UK plugs and sockets, 240V 13A rated, with a fused plug.
[23:20:24] <andypugh> (I don't like the European plugs :-)
[23:20:44] <ds3> http://www.epanorama.net/documents/groundloop/schuco_male.gif
[23:20:50] <ds3> that's what I am calling a european plug
[23:21:11] <andypugh> Have a look at http://en.wikipedia.org/wiki/Domestic_AC_power_plugs_and_sockets
[23:21:16] <andypugh> It's not that simple.
[23:21:19] <ds3> nice thing about the european plugs is they are somewhat common at the surplus piles around here
[23:22:04] <Valen> use australian 240V plugs?
[23:22:08] <ds3> andypugh: I looked at that page... trying to gather a bit more concensus
[23:23:19] <ds3> Valen: so that's what they are called... the AU plug is part of the adapter stack the seller uses :(
[23:23:37] <andypugh> For equipment I would use the Neutrik PowerCON connectors (in fact, I did) as Commando (IEC 60309) are too bulky. After that I like the UK mains plug (shrouded terminals, shutters on the sockets).
[23:24:13] <Valen> If you wanted to you could just use IEC plugs, the ones computers use
[23:24:36] <Valen> they come in a number of amp ranges and locking configurations
[23:24:50] <ds3> Valen: I am seriously considering that unless someone points out an issue with that
[23:25:04] <ds3> I can get those cables cheap and connectors are plentiful
[23:25:59] <Valen> I cant see a problem with them? if they meet the amp ratings
[23:27:23] <ds3> 'k
[23:27:54] <andypugh> I have used them internally. But I still advocate the PowerCON connectors if you can get them locally. The IEC C14 plugs are 10A rated, the PoerCONs are 20A
[23:28:17] <Valen> if your not putting 20A through them then theres not much point ;->
[23:28:28] <Valen> you can get those IEC plugs at 20A too
[23:28:44] <Valen> they use them on UPS and power strip stuff
[23:28:59] <andypugh> That's 16A according to Wiki
[23:29:05] <Valen> those powercon ones do look pretty good
[23:29:08] <andypugh> http://en.wikipedia.org/wiki/IEC_connector
[23:29:14] <ds3> the ratings on the machine is about 600W
[23:29:28] <ds3> and it is going to be limited by a 110:220V xformer to 1000W
[23:29:57] <ds3> I know the IEC connectors are use on telcom equipment; just never seen it on machinery
[23:30:11] <andypugh> So, 3A then? use nails and sellotape :-)
[23:31:08] <Valen> 22cal bullets for fuses
[23:31:42] <andypugh> Audible warning of overload, what could possibly go wrong?
[23:32:16] <Valen> aim the bullet at the power switch, your set ;->
[23:34:04] <andypugh> One thing that might not be obvious, the powerCON connectors are physically about the same size as an IEC connector. That was the main advantage for me, as I wanted 3 connectors on a 2U module.
[23:34:28] <Valen> http://en.wikipedia.org/wiki/IEC_60309 thats what he needs ;->
[23:35:44] <andypugh> Yes, that is what I was going to use, and is pretty much ubiquitous for equipment in the UK and europe. But the sockets especially are pretty bulky.
[23:38:17] <andypugh> Anyway, at 600W almost anything will do, so pick a colour you like. I have a day trip to germany tomorrow, so need to try to grab some sleep
[23:40:30] <ds3> uh...errr... I did say "bench top"
[23:40:42] <ds3> if I were doing a CNC refit on a bridge....
[23:41:07] <Dave911> andypugh:
[23:41:09] <Dave911> Valen: The hangup was the lp module, was grabbing the parport_pc module. So I put blacklist lines in to the blacklist.conf file for both lp and parport_pc and that prevented parport_pc from loading up on startup. What is strange is that lp was still loaded even though it is blacklisted. Regardless since parport_pc is not loaded, emc2 came up, loaded the realtime Parport module and it...
[23:41:10] <Dave911> ...works, no errors at all with a
[23:41:12] <Dave911> stepper configuration.
[23:41:33] <ds3> the irritating thing is all of this is preventing me from getting to the more interseting part of the setup... configuring EMC :(
[23:41:35] <Dave911> Thanks!
[23:43:35] <Valen> no worrues
[23:46:16] <Dave911> Wow, those IEC plugs are reasonably priced?? I know the welder plugs I have seen like that are pretty costly.
[23:46:18] <Dave911> Those almost look like the plugs used on semi trailers here - those are 7 pin plugs but I think the rating is 24 volts max or something similar..
[23:46:20] <Dave911> ds3 if you find those are reasonable in the US.. please let me know as they look really nice :-)
[23:46:21] <Dave911> Seems like they get all of the cool stuff in Europe first.. ;-)
[23:48:19] <ds3> uh... let me get a picture of the ones I am referring it :)
