[00:00:02] <Jymmmmm> JT-Hardinge: And of course, we can't forget the Blue Pimp Suit... http://www.platinumcostumes.com/images/products/PimptacularRoyalBlueLg.jpg
[00:21:13] <Jymmmmm> tom3p: I guess JT-Hardinge is placing his order - aweful quiet over there
[00:22:18] <aa-danimal-shop> probably poisoning your jerky
[00:23:01] <Jymmmmm> aa-danimal-shop: With as much smoking that JT-Hardinge does, you KNOW much of it has to be road kill
[00:23:51] <JT-Hardinge> * JT-Hardinge tries to find his alien wrench
[00:24:02] <aa-danimal-shop> that dont bother me. what bothers me is how long it's been dead before he scoops it up
[00:24:07] <Jymmmmm> JT-Hardinge: Look up to the sky!
[00:24:09] <JT-Hardinge> the "T" handle one you know
[00:24:27] <Jymmmmm> JT-Hardinge: ET Allen Wrench
[00:24:39] <Jymmmmm> err ET Alien Wrench
[00:24:40] <JT-Hardinge> that's called aging and cost more
[00:25:04] <JT-Hardinge> have you seen it?
[00:25:15] <aa-danimal-shop> lol
[00:25:26] <Jymmmmm> JT-Hardinge: I have Close Encounters on DVD, does that count?
[00:26:15] <Jymmmmm> * Jymmmmm suspects that JT-Hardinge doesn't realize what he said (not what he meant)
[00:26:23] <tom3p> i googled it and found its used on alien screws
[00:26:39] <Jymmmmm> Martian Sex?
[00:26:58] <JT-Hardinge> I remember it well... but not where I placed it last :/
[00:27:09] <Jymmmmm> Like aa-danimal-shop's egg?
[00:27:20] <JT-Hardinge> in the winter I tie a string on it
[00:27:46] <Jymmmmm> JT-Hardinge: Just hide the Speak-And-Spells and you'll be fine.
[00:28:22] <JT-Hardinge> I know where I used it last the summer of 69 at mudstock
[00:29:33] <Jymmmmm> JT-Hardinge: Dude, you didn't even know where your feet were in 69, 70, and 71
[00:30:15] <JT-Hardinge> dude in 69 I had a FM radio
[00:30:45] <JT-Hardinge> and no longer rode a bicycle
[00:31:05] <JT-Hardinge> gas was $0.25 a gallon
[00:31:51] <tom3p> i remember doing gate duty at goose lake rock fest, they gave us a flare and a 2x4. we dropped 'em outside the supervisors tent and made lots of great bargains with people who didnt have tickets.
[00:32:25] <JT-Hardinge> lol
[00:33:52] <JT-Hardinge> DAMM that was some bad ass gas you should have been here Jymmmmm
[00:42:15] <JT-Hardinge> WKAP
[00:43:37] <Jymmmmm> tom3p: So, besides getting more pot and ass then you ever will for the rest of your life, how many STD's did you get too?
[00:46:15] <JT-Hardinge> * JT-Hardinge would watch Fritz the Cat instead of acquiring STD's
[00:48:49] <aa-danimal-shop> man, muriatic acid made my cement floor look like new
[00:50:30] <geo01005> Did you drink it, or put it on the cement?
[00:51:30] <aa-danimal-shop> drank it and peed it on the cement
[00:54:55] <JT-Hardinge> * JT-Hardinge listens to http://www.youtube.com/watch?v=-QnBccG_ChI
[00:58:15] <JT-Hardinge> * JT-Hardinge has completed sorting the m3 from the 6-32 and calls it a night
[00:58:24] <JT-Hardinge> say goodnight Gracie
[01:01:02] <aa-danimal-shop> lol
[01:01:05] <aa-danimal-shop> night!
[01:01:11] <aa-danimal-shop> get that thing running tomorrow!
[01:01:44] <wiggly80234> Hi all, looking for help with StepConf settings for ProboStep drivers. Can anyone suggest?
[01:12:46] <tom3p> SKA! go for it JT
[01:27:21] <Jymmmmm> Jymmmmm is now known as Jymmmm
[03:10:42] <cradek> JT-Hardinge: http://www.youtube.com/watch?v=oi4CSB2HJ-4
[03:16:37] <cradek> also finally made a video of the mill accomplishing something: http://www.youtube.com/watch?v=9HLKXeWqTF0
[03:18:23] <danielfalck> cradek: nice!
[03:18:31] <danielfalck> thanks for the video
[03:18:41] <cradek> unfortunately halfway through I noticed I had the rapids turned way down... it looks slow
[03:18:55] <cradek> oh well :-)
[03:18:55] <danielfalck> make another plate :)
[03:19:01] <danielfalck> selll them
[03:19:03] <danielfalck> sell
[03:19:16] <cradek> I could make those in my sleep
[03:22:23] <cradek> if I'd get the braking resistor installed, I could tap a lot faster
[03:23:42] <danielfalck> I like the gui you have there
[03:25:25] <cradek> thanks - that's touchy
[03:26:05] <cradek> I wrote it because of this machine. no keyboard/no mouse.
[03:27:59] <danielfalck> that's exactly what is needed at a factory
[03:28:28] <danielfalck> all business and nothing extra
[03:28:53] <cradek> yes I think it fills that niche
[03:33:46] <danielfalck> cradek: are you using an air or hydraulic collet closer on your Hardinge?
[03:33:53] <cradek> air
[03:34:37] <danielfalck> do you ever use a piston inside the spindle to push stock out against a stop on the turret to set it's length?
[03:35:07] <cradek> nope, but I often use a hook (like a fat parting tool) to cut into the stock and pull it
[03:35:29] <danielfalck> we use air pressure in a lot of lathes to push a piston with o-rings to advance the stock
[03:35:39] <cradek> on some parts I get lucky and can cut away the mess that makes - otherwise I just have to waste it
[03:35:50] <danielfalck> the rear end of the draw tube has a rotary union attached
[03:36:20] <cradek> that sounds like it would work better, but my scheme is very much simpler
[03:36:30] <danielfalck> we position the turret stop the appropriate distance from the spindle, then open the collet
[03:36:47] <cradek> sounds neat
[03:36:53] <danielfalck> the bar pushes out against the stop then we close the collet
[03:37:15] <danielfalck> it only takes about 20 lbs of pressure
[03:37:34] <danielfalck> you can find rotary unions in McMaster Carr (I think)
[03:49:31] <danielfalck> something like this: http://www.deublin-catalog.com/product/17-025-012-17-series
[03:49:53] <danielfalck> to transfer air through the back of the spindle and seal it up
[03:50:45] <cradek> do you use special collets that aren't cut through, or does that just leak?
[03:51:04] <cradek> oh I guess you could use the inside thread for another seal
[03:51:44] <danielfalck> you make a piston with o-rings that is the pusher
[03:51:58] <cradek> oh I get it
[03:52:27] <danielfalck> cut a cone in the front of the piston and it will self center the stock
[03:52:48] <cradek> neat
[03:52:59] <danielfalck> it's so simple once you see it
[03:53:08] <danielfalck> and it's bullet proof
[03:53:47] <danielfalck> I think that Omni Turn uses something similar
[03:55:34] <cradek> so is your plunger 6' and stock 6'? that's a huge stickout if so
[03:56:07] <danielfalck> if you use 4' bars it works pretty well
[03:56:33] <danielfalck> the back end of the spindle is enclosed- some lathes need extensions for the back
[03:56:56] <danielfalck> you could do the same thing on a shorter bar/spindle set up
[03:58:05] <danielfalck> take a picture of your lathe from the front and post it somewhere- I could make you a quick sketch of how it could be done
[03:59:53] <cradek> thanks - I'll bug you about it if I get to where I need it
[04:00:01] <danielfalck> cool
[04:00:18] <danielfalck> when you need to make over 200 of something it will come in handy
[04:01:30] <cradek> I'm probably going to make a couple thousand of these little disks - but it makes 150 in one setup now - no problem
[04:01:47] <cradek> without the follower it was 6!
[04:02:17] <danielfalck> that video was what made me bring up the air bar pusher idea
[04:02:29] <cradek> yep I understand
[04:03:43] <danielfalck> I've been heavily into set up linux software on the mac lately and haven't done anything with emc- I hope to rectify that someday
[04:04:22] <danielfalck> I don't check in much unless I see URLs for youtube videos
[04:04:28] <cradek> heh
[04:04:37] <danielfalck> machine porn
[04:15:01] <tom3p> danielfalck: hey dan, thx for the link on those unions, i needed a high pressure water connection for an edm drill spindle
[04:23:17] <danielfalck> tom3p: good deal
[05:39:26] <ds3> what is the current, intended behavior if a feed rate is not realizeable? i.e. G01 X0 Y0 F200000.00
[05:39:56] <Valen> i believe it is just limited to max feed rate
[05:43:48] <ds3> is there a way to it fault instead?
[05:59:31] <Valen> not that I know of, its a feature not a bug
[05:59:44] <Valen> you can use it to limit the feed rate and change it as you go
[06:00:13] <Valen> you could just process the gcode file though unless your feed rate is being worked out by a formula or some such in the code itself
[06:02:18] <ds3> that is indeed the case
[06:02:43] <ds3> things like turning corners could get interesting
[06:04:25] <Valen> cant just define it with enough margin?
[07:56:46] <ds3> arrrgggg.. what is Axis doing when it loads a file?
[07:57:02] <ds3> it seems to sit there aweful long time when loading a 5-6 line file
[07:58:54] <micges_work> ds3: can you pastebin.ca this file?
[08:00:45] <ds3> sure
[08:02:42] <ds3> http://pastebin.ca/1805506
[08:02:51] <ds3> it is incredibly simple
[08:06:10] <micges_work> how long is it loading?
[08:08:31] <ds3> more then 10minutes
[08:08:36] <ds3> after taht I just kill -9'ed it
[08:08:50] <micges_work> eww
[08:09:13] <micges_work> what system, what emc2 version?
[08:09:13] <ds3> it that time, it has rendered the diagonal line in the preview
[08:09:29] <ds3> 2.3.0 installed off the current livecd
[08:09:46] <ds3> the machine is ancient but I have tried it on slower machines (K6-2/500)
[08:09:57] <micges_work> try upgrade it to latest 2.3.4 emc version
[08:10:22] <ds3> upgrading is not a easy process (no net access)
[08:10:46] <ds3> is there another that is installed by the LiveCD setup?
[08:11:20] <micges_work> live cd was year ago
[08:11:33] <ds3> I understand it may be out of date
[08:13:01] <micges_work> http://www.linuxcnc.org/hardy/dists/hardy/emc2.3/binary-i386/emc2_2.3.4-1_i386.deb
[08:13:26] <micges_work> download to flash and install it on that system
[08:30:39] <ds3> is there a particular change that might be related?
[08:31:04] <ds3> i really do not like the idea of upgrade foo just to see if it fixes a problem
[08:31:34] <ds3> this is a pretty fundamental behavior that should not have pushed out if it was really a bug
[08:36:50] <archivist> ds3 it loads instantly here version is 2.2.8
[08:40:18] <ds3> more reason to be upgrade adversed
[08:40:43] <ds3> allthese problems happened when I upgraded to get stepconf... things were working fine with the simulator before
[09:00:36] <MrSunshine> is it posible to turn threads on stuff without having a servo motor as the motor for the lathe? :)
[09:00:45] <MrSunshine> like a tachometer or whatever they call it insted?
[09:01:34] <archivist> you need spindle feedback and an index pulse on a lathe
[09:02:16] <MrSunshine> index pulse?
[09:02:26] <MrSunshine> just something that pulses each round ?
[09:02:32] <archivist> yes
[09:02:51] <archivist> needed so you know a start angle
[09:03:26] <MrSunshine> but it would require just one pulse each turn ?
[09:03:39] <MrSunshine> or would i need a real indexer that gives like 360 pulses or something? :)
[09:04:26] <archivist> some have got away with just the index pulse, I dont recommend
[09:05:44] <MrSunshine> but shouldnt that be as easy as having a say 100mm diameter wheel that i put up in the cnc mill, mill out small cavities for magnets, glue them in, stick it on the lathe and read them with a hal sensor? :)
[09:09:50] <archivist> mill slots for an opto, you need consistency
[09:10:32] <MrSunshine> hmm, a hal sensor wouldnt give me that? :)
[09:10:58] <archivist> magnetic variation and placement
[09:11:04] <MrSunshine> ahh ok =)
[10:28:01] <piasdom> g'mornin all
[10:29:31] <micges_work> hi
[11:03:54] <Valen> blast mah mill innit big enough :-<
[11:06:58] <Valen> why is it allways 250mm too small
[11:07:29] <archivist> you take on jobs too large :)
[11:07:44] <archivist> we all have the same problem though
[11:07:46] <Valen> nah I want to make a decent sized rocket motor in a bit of a fancy way
[11:08:07] <Valen> my longest travel is 500mm long but the part in question is 750
[11:09:00] <archivist> I have machined, moved reclamped in the past
[11:09:25] <archivist> or cheat and use the rotary
[11:09:47] <Valen> not going to work, its a 300mm diamiter 750mm long tube that i want to put channels into on the 750mm long axis
[11:21:31] <jthornton> http://www.linuxcnc.org/component/option,com_kunena/Itemid,20/func,view/catid,12/id,1977/lang,english/
[11:25:11] <archivist> he needs the time mode not speed
[11:25:39] <archivist> or emc needs to understand radius :)
[11:26:23] <alex_joni> archivist: emc2 does radius mode for lathes
[11:26:35] <archivist> this is milling
[11:26:47] <alex_joni> err.. right
[11:26:49] <alex_joni> just read the link
[11:28:17] <jthornton> Valen: when I have to machine a part that is bigger than my travel I make a feature that can be reached with both setups and indicate off that feature for both setups
[11:28:41] <MrSunshine_> Valen, well scale it down 33% then? :P
[11:29:47] <jthornton> If it is something that you don't want to be permanent then use hot glue to hold a gauge block on and indicate off of that for your setups
[12:41:52] <Valen> problem is its longer than the mill bed itself
[12:42:14] <archivist> use a crane on the overhang
[12:42:21] <Valen> ?
[12:42:23] <Paragon39> Hello All, Is there an alternative to this that runs under Linux? http://www.miketreth.mistral.co.uk/centrecam.htm
[12:42:41] <Valen> I spose it could work with some suitably stiff supporting structure
[12:42:47] <Valen> I have enough Z for it
[12:43:37] <archivist> Paragon39, I have done similar in linux
[12:45:01] <Paragon39> Hey archivist good to see you it's been a while since I last visited. Is it online?
[12:45:31] <archivist> no, was a while ago, not that useful for the work I was doing
[12:46:47] <archivist> webcams work in linux ok, I grabbed the image from disk in php and added lines
[12:48:33] <Paragon39> That's a good idea! Are there any alternative that you are aware of for free download?
[12:48:37] <archivist> what was the real problem was lighting, resolution and focus
[12:49:22] <archivist> one really needs a telecentric lens to use for alignment
[12:49:38] <Paragon39> I see...
[12:50:03] <archivist> or I do :)
[12:50:18] <Paragon39> LOL ... :-)
[12:50:31] <Valen> if you align to the centre though the lense shouldn't matter too much?
[12:50:47] <archivist> I want to see the centerline of a milling cutter to a few tenths
[12:51:09] <Valen> put a microscope in front of the camera
[12:51:32] <archivist> then focal distance becomes entertaining
[12:51:44] <Valen> hint, zero your tool first ;->
[12:51:55] <archivist> you cant
[12:52:11] <Valen> you could mechanically zero it no?
[12:52:19] <Valen> so you dont run the tool into the lense?
[12:52:40] <Paragon39> Thanks for the info Guys... I've got to split as work is calling :-(
[12:53:37] <archivist> tooth form for a clock gear cutter is a pain
[12:54:15] <Valen> want to make sure you don't turn the spindle on if the camera is in it ;->
[12:54:42] <Valen> a really short cable on the camera and a usb extension lead sounds like a good idea to me
[12:56:19] <archivist> I actually want the average width on a curved point of the form to get effective depth of cut
[12:57:03] <archivist> on some thing about 10 thou wide for a watch cutter
[13:52:13] <jthornton> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Adding_More_Controls_To_Simple_Remote_Pendant
[13:52:30] <jthornton> * jthornton is off to work
[14:02:34] <alex_joni> jthornton: fixed your 5i20?
[14:02:52] <JT-Hardinge> not yet
[14:03:48] <alex_joni> :/
[14:19:37] <i_tarzan> archivist, does it mean you use your sight and manually centering for single piece works?
[14:51:09] <archivist> yeas and no, center with some magnifier and adjust cut during the job
[14:51:57] <archivist> currently there is no automated way of setting the depth of cut for certain gear types
[14:52:31] <cradek> with cnc do people really spend much time lining up with scribe or punch marks? I bet I do that once for every hundred times I use an edge for reference
[14:53:04] <archivist> I have to setup every time
[14:53:05] <i_tarzan> gear generators automated
[14:53:21] <cradek> (I'm talking about this webcam application)
[14:54:05] <i_tarzan> edges not for single piece work
[14:55:01] <cradek> I bet I use 90% edges, 9% hole center, 1% scribe or punch mark
[14:55:27] <cradek> a probe is surely better than a webcam for finding edges and hole center
[14:55:43] <cradek> I bet webcam is better than probe for scribe or punch marks
[14:56:11] <archivist> probe cant work for my gear cutters
[15:00:56] <i_tarzan> hole work no good
[15:03:18] <archivist> for me, no available hole and cannot measure from spindle as the change to tool would lose measurement
[15:04:03] <elmo40> any way to use EMC and a CCD camera to do part comparisons? Something similar to this: http://qurl.org/ow0
[15:04:51] <elmo40> compare a sheetmetal stamped part to a CAD drawing.
[15:06:27] <i_tarzan> seems expensive
[15:08:39] <archivist> elmo40, the lens on that is one of the special bits
[15:33:03] <sealive> Hi from Germany.
[15:33:14] <sealive> i just got into the forum
[15:34:41] <sealive> mow with the last things to do on the 3th homemade cnc i will start with linuxcnc
[15:36:27] <sealive> Quest: where in the large docu can i fand the interface settings for the lpt searching quied a wile
[15:36:56] <sealive> i'am used to work with nc-frs
[15:48:30] <JT-Work> sealive: to add another parallel port?
[15:53:12] <sealive> no ! ifound what iam searcht for in getting startet
[15:53:28] <sealive> i first viewd the extend pdf and it wars not there
[15:53:51] <sealive> i have seen that i can change the dataports of the lpt
[15:54:21] <sealive> thats nice cause i got some old pc from robotting that have lost 1 dataport
[15:56:13] <sealive> as i speek Data1 of lpt1 is broken so i cant use it for ncfrs here it seams to work i simply change axis x from 0,1 to 6,7
[15:58:32] <sealive> so i'am impresst and will start to use it as my new cnc-mocion controlll prog!
[16:02:06] <sealive> Thanks till here i wik come back when i run in a problem!
[17:05:24] <aa-danimal-shop> mornin
[17:05:57] <micges> evening
[17:06:28] <aa-danimal-shop> 9 am here
[17:07:23] <micges> 6pm here
[17:07:59] <aa-danimal-shop> where's here?
[17:08:09] <micges> Poland
[17:08:17] <aa-danimal-shop> ahh
[17:08:36] <aa-danimal-shop> California here
[17:09:29] <aa-danimal-shop> Back when i lived in Connecticut, almost every machine shop spoke primarily Polish
[17:10:09] <micges> cool!
[17:12:04] <aa-danimal-shop> I learned pretty much everything i know about machining from the Polish actually :)
[17:15:38] <micges> heh strange, I've lerned primarly from english :D
[17:18:58] <aa-danimal-shop> ha
[17:19:43] <cradek> aa-danimal-shop: http://www.youtube.com/watch?v=oi4CSB2HJ-4
[17:22:00] <elmo40> archivist: i_tarzan: i dont mean to make that machine. i mean to have a webcam take a photo of the piece that was made then use software recognition to compare it to a DWG file.
[17:23:54] <elmo40> micges: my shop is owned by Polish people.
[17:24:07] <elmo40> in Ontario, Canada.
[17:29:41] <aa-danimal-shop> cradek: nice!
[17:31:22] <cradek> I'm going to have to run the cutting oil over to it, with a long flexible hose
[17:31:30] <aa-danimal-shop> i was just gunna ask
[17:31:42] <cradek> after a while, it all heats up and the bar doesn't spin freely anymore (the hole is a very close fit)
[17:31:55] <cradek> it's brass so it doesn't need it for cutting, but the follower does
[17:31:57] <aa-danimal-shop> probably if you didnt, it might wear out or score up your steady rest eventually
[17:32:12] <cradek> yeah, and it should be harder than aluminum anyway
[17:32:25] <aa-danimal-shop> yea
[17:32:48] <cradek> that part is disposable (and currently made poorly compared to the rest of it)
[17:33:15] <aa-danimal-shop> maybe put a little fitting on there to inject the coolant right on the material inside the steady rest?
[17:33:28] <cradek> yeah I think so
[17:33:36] <cradek> drill a cross hole and feed it in there
[17:33:40] <aa-danimal-shop> yea
[17:34:02] <aa-danimal-shop> you can use those little push to connect fittings with some 1/8" or 1/4" tubing
[17:34:39] <cradek> also, tapping the big plate for it: http://www.youtube.com/watch?v=9HLKXeWqTF0
[17:35:31] <terrylm> Hi all
[17:35:55] <aa-danimal-shop> showoff lol
[17:35:59] <aa-danimal-shop> hi terrylm
[17:36:25] <terrylm> Lathe cutter comp question...
[17:36:53] <terrylm> strait in tool, strait sides 0.016 radius nose.
[17:38:16] <terrylm> Need it to slide down an inside wall, head toward Z- cutting some curves/tapper and pull out on a wall on the other side of the tool.
[17:38:33] <terrylm> So the tool will be cutting on both sides.
[17:38:39] <terrylm> Used G41.
[17:39:20] <terrylm> Get an error that the radius of the first curve (G2) is too small to reach the end point.
[17:39:52] <cradek> that's not actually a cutter comp error. it just means your arc doesn't make sense
[17:40:06] <terrylm> Looking at where the tool is coming in, it is in the wrong place, too Z+ by half the tool or more.
[17:40:07] <cradek> if you change your G41 to G40 you'll still see that error
[17:40:23] <cradek> is your arc R or IK?
[17:40:33] <terrylm> Used R
[17:40:50] <cradek> ok, check that your R is right, then
[17:41:07] <terrylm> It is, 0.042
[17:41:26] <cradek> then check that your XZ target are right...
[17:41:36] <terrylm> Did.
[17:41:42] <cradek> pastebin the gcode?
[17:41:50] <terrylm> The tool is too far Z+...
[17:42:18] <terrylm> Thus it can not reach the end point because it start in the wrong place.
[17:42:21] <aa-danimal-shop> terrylm: are you compensating for diameter?
[17:42:30] <cradek> ok, so the starting point is not what you expect
[17:42:47] <terrylm> Used a G43, is something else needed?
[17:42:47] <cradek> I recommend turning off g41 and checking the program that way
[17:42:59] <terrylm> OK
[17:43:19] <cradek> then we can see whether we need to work on the cutter comp entry or the basic gcode
[17:43:53] <cradek> or maybe you have the wrong tool orientation, or something like that
[17:44:02] <skunkworks_> cradek: Nice!
[17:44:21] <aa-danimal-shop> not sure if with a G18 if you need to double the I value
[17:44:31] <cradek> he says he's using R format
[17:44:34] <aa-danimal-shop> oh
[17:44:44] <cradek> but yes, I is in radius units
[17:45:33] <aa-danimal-shop> so for a 90 degree corner radius, i would be double k?
[17:45:45] <aa-danimal-shop> in diameter mode that is
[17:45:49] <cradek> no, they would be the same
[17:45:53] <aa-danimal-shop> oh
[17:45:54] <cradek> it's X that's in diameter
[17:45:55] <aa-danimal-shop> ok
[17:46:12] <aa-danimal-shop> that makes more sense
[17:46:27] <terrylm> I am using diameter mode.
[17:47:18] <cradek> diameter mode can be confusing for arcs
[17:49:29] <terrylm> I'm going to step out to the shed and work on it, be back in a bit...
[17:49:30] <terrylm> Almost forgot, I figured the center of the tool for Z touchoff, not either side, that is correct for a strait in tool right?
[17:49:42] <cradek> depends on the orientation
[17:49:51] <cradek> http://www.linuxcnc.org/docs/devel/html/lathe_lathe-user.html
[17:50:23] <cradek> if the end of the tool is round, and you touch off the center of the round, that's orientation 9
[17:51:10] <cradek> make sure you understand that orientation picture
[17:51:33] <cradek> if your tool looks like it's in the wrong place when you turn on comp, I bet you have orientation wrong
[17:52:56] <terrylm> ... orientation is 6, though the tooling is all really backside tooling, AXIS seems to be frontside oriented.
[17:53:32] <cradek> just pay attention to the +X and +Z on that picture when picking orientation
[17:53:50] <cradek> if it's 6 that would mean it points toward -X
[17:54:31] <terrylm> Then 6 is right.
[17:54:40] <terrylm> yes.
[17:54:49] <cradek> ok but 6 does not have the origin at the radius's center
[17:55:03] <cradek> you'd have to touch off the end of it for orientation 6
[17:55:18] <terrylm> OH, the 9?
[17:55:37] <terrylm> then 9
[17:55:53] <cradek> use whichever is easiest to touch off
[17:58:43] <terrylm> OK, if using orientation 9, when touching of in X, doing a test cut, would it be the cut dia. or the dia. + tool radius?
[17:59:01] <cradek> neither
[17:59:09] <cradek> cut dia + tool DIA
[17:59:10] <terrylm> ... or dia. + 2*tool radius
[17:59:16] <cradek> right
[17:59:17] <terrylm> OK
[17:59:22] <terrylm> Thanks
[17:59:31] <cradek> welcome
[18:00:19] <terrylm> The values in the tool table for the tip size are radius even when working in diameter mode, right?
[18:00:51] <cradek> the tool table value is tip diameter
[18:00:59] <cradek> http://www.linuxcnc.org/docs/devel/html/lathe_lathe-user.html
[18:03:10] <terrylm> Oh, missed that, Thanks again. will go try all this in info out...
[18:03:28] <cradek> no problem. you will get it :-)
[18:03:37] <aa-danimal-shop> i was making a new pivot mount for my lathe's monitor/keyboard, and i dropped my monitor :(
[18:03:43] <terrylm> Hope so.
[18:03:51] <aa-danimal-shop> now it has about a 4 inch black strip down the middle
[18:03:57] <cradek> aa-danimal-shop: dangit
[18:04:07] <aa-danimal-shop> yea
[18:04:10] <terrylm> bummer....
[18:04:16] <aa-danimal-shop> i wonder if it's fixable
[18:04:23] <terrylm> no
[18:04:31] <terrylm> LCD right?
[18:04:34] <aa-danimal-shop> yea
[18:04:37] <terrylm> no
[18:04:40] <aa-danimal-shop> :(
[18:05:10] <aa-danimal-shop> well at least the pivot came out nice
[18:05:24] <aa-danimal-shop> craigslist, here i come
[18:06:58] <terrylm> Were I live the county goverment has a 'disposal' department that gives things to non-profit orginazations, lots of computer stuff. I work with a non-profit (volunteer), and have gotten LCDs free, computers too.
[18:07:22] <aa-danimal-shop> nice
[18:07:43] <terrylm> See if your local gov. does something like that...
[18:08:05] <aa-danimal-shop> i'm non-profit, but not in the way they mean
[18:08:46] <terrylm> Well, just volunteer with a local non-profit, they are every where and always in need of volunteers.
[18:10:31] <terrylm> Well, I've got to go, try to run my part, then got to go to work... yuck.
[18:10:39] <terrylm> Thanks again all.
[18:12:48] <aa-danimal-shop> found the same one i dropped for $50
[18:12:50] <aa-danimal-shop> locally
[18:12:55] <aa-danimal-shop> a dell 17"
[18:13:27] <aa-danimal-shop> which is ideal because it has some weird mount, and this way i wont have to modify my bracket
[19:30:26] <bosko> Hello everyone!
[19:31:03] <i_tarzan> h
[19:31:14] <aa-danimal-shop> hi
[19:35:10] <jackc> word
[20:03:22] <ds3> is tkemc still available on the LiveCD?
[20:03:32] <JT-Work> yes
[20:03:49] <ds3> how do I tell emc to use that instead of axis?
[20:07:17] <JT-Work> in your ini file
[20:07:40] <ds3> 'k thanks
[20:08:06] <JT-Work> ds3: http://www.linuxcnc.org/docview/html//config_ini_config.html#sub:[DISPLAY]-section
[20:08:40] <ds3> I got 5 tabs open on that site right now :D
[20:10:03] <ds3> OTH, an upgrade to 2.3.4 does seem reasonable... there is one bug fix that might be related
[20:14:46] <ds3> in the docs, a "machine unit" is 1 inch or 1mm, right?
[20:19:07] <MrSunshine_> * MrSunshine_ just did his first buy on ebay :P
[20:19:12] <MrSunshine_> lets see if it arives =)
[20:19:36] <JT-Work> ds3: yes
[20:23:15] <ds3> think I am reloaded with ideas on how to solve this
[20:26:35] <tom3p> if its ideas.. the unit could be furlongs or wan or degrees. the unit is 'the whole thing' , and the descriptions of other many parts in the ini are related to the 'whole thing' like how-many-tiny-bits are in the whole-thing
[20:26:40] <jackc> anyone have ideas as to how many steps/rev i need on my encoder on the lathe spindle for good threading?
[20:27:33] <skunkworks> how are you counting?
[20:28:01] <skunkworks> (hardware or software?)
[20:29:26] <jackc> softwatte, steps in parallel port (thats the idea anyway)
[20:29:37] <jackc> read on the wiki how to do a 1 step/rev for spindle speed control
[20:29:45] <jackc> wondering if i can hack it up enough to do threading
[20:30:20] <jackc> the problem is that too many steps/rev and the PPT cant read it fast enough, so it limits my top spindle speed
[20:30:38] <seb_kuzminsky> jackc: yeah, that's the real problem with servos on a parallel port
[20:31:04] <jackc> i mean i can make a divider for normal use and switch it off for slow-spindle threading maybe
[20:31:08] <jackc> but thats kinda ghetto
[20:31:11] <cradek> jackc: use as high resolution as you can read reliably at the spindle speed you want to use
[20:31:26] <jackc> cradek: whats 'normal' for spindles?
[20:31:32] <cradek> let us know what you come up with and we can check your math
[20:31:43] <jackc> ok ill look for parralel port stats
[20:31:52] <cradek> depends on your desired spindle speed and your base period
[20:32:03] <jackc> hm
[20:32:29] <seb_kuzminsky> jackc: the limiting factor won't be the parport itself, it'll be how frequently you can read it, ie how fast you can reliably make your base thread
[20:33:08] <ds3> I need ideas cuz I am running in the the most rediculous problems
[20:33:14] <jackc> interesting, i figured the hardware itself would be angry but ok
[20:33:22] <ds3> like axis getting stuck loading a 5-6 line program
[20:34:34] <ds3> I'd think if I can get jog to work, running a test program should be a cinch... apparently not
[20:35:35] <tom3p> ds3 dont mess with units yet. describe what you see happen when you try to run a test program
[20:36:03] <ds3> tom3p: I load the program. and it sits there with the busy cursor for at least 9+ minutes
[20:36:12] <cradek> so what's the program
[20:36:25] <ds3> tried it many times and sometimes I even get a rendering in the window
[20:36:39] <tom3p> pastebin the program
[20:36:46] <ds3> where's the channel's logs?
[20:36:55] <ds3> I pasted bin it last night but lost the URL
[20:36:57] <seb_kuzminsky> logger_emc: bookmark
[20:36:57] <seb_kuzminsky> Just this once .. here's the log: http://www.linuxcnc.org/irc/irc.freenode.net:6667/emc/2010-02-22.txt
[20:37:21] <tom3p> http://www.linuxcnc.org/irc/irc.freenode.net:6667/emc/
[20:37:43] <ds3> http://pastebin.ca/1805999
[20:38:30] <ds3> it is hard to get much simplier then this as a test program :D
[20:40:51] <tom3p> ok, it loaded in the blink on an eye here and runs ok, so... try a stock program from the emc install.
[20:51:43] <ds3> tom3p: what version?
[20:52:19] <ds3> I know that if I strace it, it is looping between X server I/O and waiting on futex'es
[20:55:25] <seb_kuzminsky> ds3: Is the rest of your system responsive while Axis is trying to load your program? Can you open new windows, browse the web, etc? what's your base period? maybe rtai is using so much cpu that there's none left over for linux
[20:56:22] <ds3> seb_kuzminsky: it is responsive enough that i can open an xterm to run top
[20:56:33] <cradek> any error on emc's stdout/stderr?
[20:56:39] <ds3> top shows a load of 3-4 but I donno if it is CPU bound or RTAI messing with the load calculator
[20:56:56] <seb_kuzminsky> i think rtai doesnt show up on linux's load, or in top
[20:57:05] <ds3> I don't think so based on looking at the /tmp/*emc* files but I donno for sure as I used the link that stepconf generated to start it
[20:57:40] <cradek> run it in a terminal
[20:58:01] <tom3p> yah run emc from a terminal
[20:58:13] <ds3> seb_kuzminsky: I from testing, I had 30000 as the base period and I up'ed it to 50000 just to try to eliminate that possiblity
[20:58:25] <ds3> okay, I will add that to the list of things to try
[20:59:31] <ds3> when axis loads a file, what exactly does it do?
[20:59:53] <cradek> interprets it to generate the preview
[20:59:57] <ds3> from what i can tell, it parses it once to generate teh rendering but is there anything else it could possibly be hanging on?
[20:59:59] <cradek> on our machines anyway
[21:00:14] <cradek> you're going to have an error on stdout. see what it is.
[21:00:16] <ds3> this is a very simple stepper setup (pure stepconf config)
[21:00:29] <ds3> Okay.
[21:00:34] <cradek> don't sit here guessing what might be wrong - troubleshoot
[21:00:58] <ds3> I am not near the shop at the moment so I am putting together a list of things to try tonight
[21:01:08] <cradek> oh, I see
[21:01:09] <ds3> but the fact that you are sure there is an error is very reassuring
[21:01:16] <bosko> Dear! As i see all brain masters are there. I have a question for you, regarding a machine config. Friend have a old Press&Brake machine, and my question is: What is the simplest way to put axis to certain position? Via keyboard, lets say to 5 centimeters, and then add +1 centimeter?
[21:01:35] <cradek> g0 x5
[21:01:40] <cradek> er g0 x50
[21:01:43] <cradek> then g0 x60
[21:02:07] <bosko> Can i do it from VCP? with huge display?
[21:02:54] <cradek> you can't enter an mdi command on a vcp panel
[21:03:08] <cradek> and I think there are no keyboard entry widgets
[21:03:38] <bosko> Press (hydraulic valves-combination of them) can be done in ladder logic, is that correct?
[21:03:56] <cradek> yes of course
[21:03:58] <ds3> side note - I sat through a Mach3 demo and their stuff is remarkably like EMC2... donno if you guys are feeding into them or vice versa
[21:04:00] <bosko> So directly in MDI window?
[21:04:21] <cradek> ds3: mach3 uses the old public domain emc interpreter from the old days
[21:04:33] <ds3> cradek: I mean the UI
[21:04:45] <seb_kuzminsky> cradek: cool, i did not know that
[21:04:54] <ds3> they have a bit more polished probing setup but other then that it is remarkably alike
[21:05:04] <cradek> ds3: no idea about that. I am sure some ideas are common on every cnc control
[21:05:30] <ds3> I wish the fanuc or haas stuff did as many things :D
[21:05:49] <ds3> or course right now, I'll settle for anything that just works ;)
[21:06:20] <bosko> cradek: Is there any other way to insert MDI command from interface. It can be done from USB joysticks, but not from keyboard?
[21:06:32] <cradek> I bet our probing is actually more powerful. they probably have probing-related buttons that we don't.
[21:06:39] <seb_kuzminsky> bosko: joysticks jog, they dont do mdi
[21:06:51] <cradek> bosko: you use a keyboard to enter an mdi command: you simply type it
[21:06:58] <ds3> no doubt about that...but that's a UI function
[21:07:01] <cradek> bosko: do you know what mdi is?
[21:07:36] <ds3> I could use a USB joystick MDI input
[21:07:48] <ds3> it is one the last few reasons I have a keyboard in the shop
[21:08:21] <cradek> touchy lets you do mdi without a keyboard
[21:08:29] <cradek> and oh is it cool
[21:09:08] <ds3> is there a page? touchy in the wiki didn't turn up anything
[21:09:36] <bosko> I think /hope so. It stands for Manual Data something. Basically, command line interface for manual command ..
[21:09:37] <cradek> http://www.linuxcnc.org/docs/devel/html/gui_touchy.html
[21:10:06] <ds3> odd that didn't get found *shrug*
[21:10:15] <cradek> it's not wiki, it's in the docs
[21:10:31] <ds3> oh and the wiki doesn't search docs?
[21:10:37] <cradek> hm, that's some pretty basic documentation :-)
[21:10:42] <cradek> no, they are sadly unrelated
[21:10:46] <ds3> DOH
[21:11:15] <ds3> I like it...
[21:11:34] <ds3> now if only emc ran on an ARM board or something with a real SPI bus
[21:11:35] <bosko> There is a touchy interface somewhere else, i have seen it..
[21:11:57] <cradek> ds3: mdi page (slightly out of date picture): http://timeguy.com/cradek-files/emc/touchy-mdi.png
[21:13:03] <ds3> that loosly resembles what FANUC had, IIRC
[21:13:34] <cradek> perhaps there are no new ideas under the sun
[21:13:52] <ds3> that UI makes me want to get a TS setup
[21:14:13] <ds3> and I have a nice LCD/TS ready to go but it is not x86 friendly
[21:14:20] <bosko> http://www.cnczone.com/forums/showthread.php?t=92072
[21:14:27] <bosko> That is touchy
[21:15:00] <cradek> yes
[21:15:20] <cradek> my machine with a touchy panel http://timeguy.com/cradek-files/emc/jr.jpg
[21:15:31] <ds3> can touchy be run remotely on a non RTAI machin for UI only?
[21:15:52] <bosko> AND MY CONGRATULATIONS TO YOU, Mr. Chris!
[21:16:04] <cradek> you could use remote X to do that, but the hard controls need to be hooked to the realtime machine of course
[21:16:41] <bosko> I see i need to go into python...
[21:17:23] <ds3> I ought to find out if the LiveCD kernel has support for CDC ethernet
[21:17:49] <cradek> compared to machine tools, touchscreens aren't that expensive
[21:18:05] <cradek> you want one that will hold up to coolant/oil
[21:18:13] <ds3> compared to what I can buy TS's for.... TS's for PC's are outright expensive
[21:18:51] <cradek> $17.99 http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=290404024553
[21:18:53] <clytle374> touchscreens don't go the best with greasy finger either
[21:18:55] <ds3> the problem is no one makes a 7-8" monitor for use with desktop PCs
[21:19:37] <seb_kuzminsky> lol, a crt touchscreen
[21:19:37] <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/"
[21:19:40] <cradek> true, it's hard to find little ones
[21:19:49] <bosko> cradek: Basically you have done already what i think i need.
[21:19:53] <ds3> I can get brand new 7" TS's cheap
[21:19:59] <cradek> seb_kuzminsky: they are sturdy...
[21:20:06] <ds3> if the PCs output a raw LCD signal, that is just trivial to do
[21:20:06] <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/"
[21:20:20] <bill2or3> what about those screens for cars? I think some of them have vga in.
[21:20:36] <cradek> bill2or3: I foolishly bought one - the touchscreen part failed after about 20 minutes of use
[21:20:40] <ds3> bill2or3: how much?
[21:20:40] <bill2or3> d'oh.
[21:20:55] <cradek> they're surely just the cheapest crap it's possible to make
[21:20:55] <bill2or3> I think they're < $200ish
[21:21:00] <bill2or3> go china!
[21:21:03] <ds3> ouch... $200ish is steep
[21:21:32] <ds3> a 7" display can be build for sub $100 in small volume and sub $50 in large enough volume
[21:21:52] <ds3> but the TSC controller is a pain on the PCs
[21:21:58] <cradek> maybe there's a better brand I suppose...
[21:21:59] <ds3> s/TS/TSC/
[21:22:05] <bill2or3> * bill2or3 won 4 centent CN0142 drivers. :-)
[21:22:06] <ds3> the other way around
[21:22:10] <bill2or3> thanks ebay.
[21:22:16] <cradek> I'd buy a microtouch crt before I'd buy another new chinese special one
[21:22:28] <cradek> (actually I have a microtouch crt on my lathe)
[21:22:39] <ds3> I'd much rather see emc running on an ARM ;)
[21:22:55] <celeron55> how about getting a screen and the touchscreen film separately?
[21:23:17] <ds3> celeron55: you'd still need a TSC
[21:23:24] <bill2or3> I bought a separate TS overlay for a laptop and installed it.
[21:23:29] <cradek> they do make add-on overlays
[21:23:50] <celeron55> http://www.dealextreme.com/details.dx/sku.12561
[21:23:58] <ds3> they sell kits to do that for the eeePC's
[21:24:11] <cradek> they are adequate but you get more error because of space between the touch panel and the monitor
[21:24:13] <bill2or3> that's where I got it, even, except it was a 10" version.
[21:24:17] <ds3> but eee's don't offer PP's
[21:24:35] <bill2or3> it arrived broken, the whole thing was a pain in the ass.
[21:25:01] <bosko> What about some POS terminals?
[21:25:12] <bosko> Like for restaurants etc...
[21:25:14] <ds3> drivers
