[00:01:50] <tom3p> re hal, i see it ought to be 'source fname.hal' too bad it doesnt work for me :(
[00:03:52] <tom3p> when halruns saves the current configuration for a u32 pin, it saved "setp ena-const-u32.0.value 00000007" which it cannot load "01feb2010.hal:18: value '0000000E' invalid for U32"
[00:05:41] <tom3p> err copied wrong pin to describe that "setp ena-const-u32.1.value 0000000E"
[00:09:05] <tom3p> editing those long hex values to simple ints fixes the load error
[00:09:32] <tom3p> "setp ena-const-u32.1.value 14" is otay pankie
[00:16:37] <Danimal-office> ds3: what kind of hardinge? hnc?
[00:17:22] <ds3> I thought most the hardinages use that t grove mount on the taper?
[00:17:46] <Danimal-office> what lathe do you have?
[00:17:53] <Danimal-office> hnc?
[00:18:17] <tom3p> hey some of the code that parses a list and generates hal files automaticly (sorta) already exists in the halun save function !
[00:18:32] <ds3> no at hardinage
[00:18:36] <ds3> not a
[00:19:48] <Danimal-office> well there's a few different hardinge lathes, with different spindle noses
[00:20:24] <Danimal-office> mine has the hardinge taper with the t shaped slot
[00:20:37] <Danimal-office> most hnc's are threaded
[00:21:06] <Valen> whats peoples opinions on round rail with linear slides for a gantry mill
[00:21:13] <Danimal-office> the chnc i believe has a more modern mount
[00:21:14] <Valen> supported rail, with ball bearing slides
[00:22:27] <Danimal-office> Valen: linear bearings have a little play in them, which isnt absorbed by friction like ways
[00:22:56] <Valen> could it be preloaded out?
[00:22:59] <tom3p> not my opinion, nut machine tool manufacturers: small light cutting machines have round ( graphite drilling machines, wood routers ) square (ibeam) rails used for cutting metal.
[00:23:05] <tom3p> but
[00:23:13] <Danimal-office> i wouldnt use linear bearings for milling
[00:23:27] <jt-plasma> Danimal-office: I have the phase converter up and running :)
[00:23:41] <Danimal-office> jt-plasma: nice!! pics?
[00:23:48] <tom3p> roto phase or electronic?
[00:23:53] <Danimal-office> roto
[00:24:07] <Valen> what would you use? and where would you get it?
[00:24:22] <jt-plasma> http://i47.photobucket.com/albums/f163/johnplctech/Hardinge/interface01.jpg
[00:24:24] <Danimal-office> i prefer ways
[00:24:28] <jt-plasma> http://i47.photobucket.com/albums/f163/johnplctech/Hardinge/interface02.jpg
[00:25:03] <jt-plasma> phase converter motor is very quiet too :)
[00:25:11] <Danimal-office> nice
[00:25:15] <Danimal-office> clean work
[00:25:22] <Valen> can you buy them as bolt on type things?
[00:25:39] <jt-plasma> not cleaned up yet LOL
[00:25:53] <Danimal-office> cleaner than mine
[00:26:12] <Danimal-office> Valen: you can buy xy tables with ways
[00:26:23] <Valen> for mega$ though
[00:26:33] <Danimal-office> get what you pay for
[00:26:36] <Valen> this is for a gantry type mill made from epoxy granite
[00:27:04] <Valen> The idea is to make it somewhat modular so you can upgrade it as you get better bits
[00:27:09] <Danimal-office> all i know is i used linear bearings on a machine i built and the vibration wasnt too good for the cut
[00:27:12] <Valen> IE from slides, to ways
[00:27:45] <Valen> the gantry is looking like its going to weigh ~150kg (300lb's) for a .5m cube of machining volume
[00:27:52] <Danimal-office> ways seem to absorb the vibrations caused by interupted cuts a little better
[00:28:21] <Danimal-office> you can try to preload them i guess
[00:28:40] <Danimal-office> i got close tollerance ones and it was still not so hot
[00:28:59] <Valen> they also seem pretty light on the load ratings
[00:29:05] <ds3> ah... all the ones i have seen have that T shaped grove
[00:29:06] <Valen> what were you cutting with them?
[00:29:18] <Danimal-office> i guess with a 300lb machine, you wont be doing tons of heavy cuts though
[00:29:28] <Danimal-office> alumininuminum
[00:29:29] <ds3> one is a HLV, IIRC and the other is a clone
[00:29:32] <Valen> 300lb's for the gantry by itself
[00:29:34] <jt-plasma> Danimal-office: you get your spindle sorted out?
[00:29:45] <Valen> without slides or motors or any other steelwork
[00:29:53] <Danimal-office> jt-plasma: no, had to finish that job first
[00:30:00] <Valen> on a "large benchtop" machine ;->
[00:30:22] <Valen> 20 inches of travel in 3 axies
[00:30:55] <jt-plasma> * jt-plasma had a successful evening so I'm heading in before I break anything
[00:31:07] <tom3p> jt-plasma: nice work
[00:31:16] <jt-plasma> thanks tom3p
[00:31:28] <Valen> tis shiny
[00:32:03] <tom3p> Valen: how many axis ? with a given work volume, the machine volume always increases with a/b/c/u/v/w
[00:32:19] <Valen> 3 axis,
[00:32:27] <tom3p> cool, np
[00:34:14] <Valen> http://www.vapourforge.com/gemill/GE1.jpg is the first plan
[00:36:19] <Valen> we are thinking though of running the Z axis through the center of the gantry and putting 4 rails on it
[00:36:45] <Valen> so there is something like an X shape there
[00:40:23] <Danimal-office> yawn
[00:40:43] <Danimal-office> Valen: cool
[00:40:49] <Danimal-office> i'm tired
[00:41:04] <Danimal-office> long weekend of work
[00:41:39] <Danimal-office> ds3: the hlv isnt a cnc, is it?
[00:43:11] <Danimal-office> The guys doing retrofits to hardinge lathes on here (including me) usually start with a lathe that's already a cnc, like the hnc or chnc
[00:45:45] <ds3> Danimal-office: not from factory but I don't see why someone can't refit it
[01:34:20] <ds3> \
[01:38:03] <Jymmm> SWPLinux: Hey, how was last night?
[01:38:37] <SWPLinux> OK
[01:38:52] <Jymmm> SWPLinux: chaos?
[01:38:55] <SWPLinux> it was pretty slow for the first hour or so
[01:38:57] <SWPLinux> then chaos
[01:39:07] <SWPLinux> the hilight for me was probably Weird Al :)
[01:39:07] <Jymmm> Lady gaga?
[01:39:17] <Jymmm> link?
[01:39:23] <SWPLinux> no, she didn't stop in, but the fan they made up to look like her did
[01:39:31] <SWPLinux> or him, or whatever she is
[01:39:34] <SWPLinux> he
[01:39:36] <SWPLinux> whatever
[01:39:38] <Jymmm> heh
[01:39:43] <SWPLinux> eonline.com?
[01:41:14] <Jymmm> snooki HAHAHAHA
[01:41:23] <SWPLinux> heh
[01:41:27] <SWPLinux> from Jersey SHore?
[01:41:34] <Jymmm> yeah
[01:41:36] <SWPLinux> The Situation also stopped in
[01:42:40] <Jymmm> OH Weird al turned out great!!!
[01:43:13] <Jymmm> Usher was the lamest
[01:43:24] <SWPLinux> yeah
[01:43:29] <SWPLinux> "I think I'll stand here"
[01:44:48] <Jymmm> SWPLinux: how did handing out the usb sticks work out?
[01:45:38] <SWPLinux> OK. it was a little bit of a wrinkle in the workflow - the person doing the web videos was also rendering the 720P videos for the sticks, which then got written on another computer
[01:45:55] <SWPLinux> and then walked across the set to the person, if they bothered to hang around for it (which they often didn't)
[01:45:58] <Jymmm> SWPLinux: AVI to GIF =)
[01:46:10] <SWPLinux> heh
[02:05:05] <Jymmm> SWPLinux: Hey, no audio, it be perfect and low overhead
[02:24:04] <SWPLinux> time to run. see you all later
[02:35:41] <Jymmm> What came first... the chicken or the puppy? http://i46.tinypic.com/m8hekj.jpg
[02:38:09] <Danimal-office> the phsycologist
[03:22:15] <Valen> wth is all that about?
[04:43:28] <tom3p> archivist: what did ERD stand for in your ERD diagrams? ( organizing bookmarks )
[04:45:02] <danimal_garage> extra rediculous diagrams
[04:50:51] <tom3p> heh, i like the work yoyoek ?? did with blender & just saw another utility that creates bas-reliefs http://wiki.blender.org/index.php/Reference/Windows/Nodes/Composite_Nodes/#Bas_relief (hey, walk like an egyptian)
[04:51:04] <tom3p> for cnc
[07:44:25] <Jymmm> join ##php

[13:41:38] <Valen> the the latest on the mailing list?
[13:41:47] <Valen> I have G-CODE program about 70 Mb and 2300000 lines. EMC loads it very very slow. Any ways to do system faster?
[13:41:59] <Valen> hmm a 70mb text file loads slowly? really
[13:53:55] <archivist> he might mean Axis loads it slowly
[13:56:22] <Valen> I believe he does
[13:57:51] <Valen> cant think what you would need that many lines to cut
[13:58:41] <archivist> large item with curves and a cam program with no clue
[13:59:51] <Valen> even so
[14:00:29] <Valen> to me the answer is fix the 70mb file not axis
[14:01:02] <archivist> probably cannot fix the cam program
[14:01:19] <cradek> you can tell AXIS to stop generating preview by adding a comment like (AXIS,stop)
[14:01:24] <Valen> most of them seem to have post processors though
[14:01:56] <cradek> http://www.linuxcnc.org/docs/devel/html/gui_axis.html#r1_11_7
[14:02:16] <cradek> oh none of you are the asker are you
[14:02:17] <Valen> tried firefox mobile today
[14:02:21] <Valen> no
[14:02:37] <Valen> I was just commenting at a guy complaining about the 70mb file loading slowly
[14:02:50] <cradek> I understand
[14:23:36] <tom3p> hah, read some code that changes the way a micro handled pwm, and the author said if you changed the control registers, it would 'pooch' all the routines that used the timer. i had to find out what 'pooch' meant. the 1st definition was 'exactly what you think it means'
[15:39:09] <Nick001> Axis-lathe - Is there a touchoff for it and how to load it Is there a GUI for the offset table?
[15:39:52] <cradek> yes there's touch off, it's the button that says "touch off"
[15:40:38] <cradek> I'm not sure if you're asking about coordinate system origin or tool length
[15:40:47] <cradek> but, you can set either with the touch off button
[15:49:33] <Nick001> Turn tool to set for x0 and z0 from the home position - m6 t1 g46 h1,,,
[15:50:34] <cradek> do you mean g43?
[15:50:43] <Nick001> right
[15:51:16] <Nick001> im not in front of the machine right now
[15:51:47] <cradek> I feel like I still don't understand your question. Can you say again what you are trying to do?
[15:54:13] <Nick001> home position is 10" from the spindle on z - need to input a # in the offset table to get z within working distance of the spindle. x is about 3" fron splindle c/l
[15:55:10] <cradek> to set the Z zero of your workpiece, move your reference tool there (the one with zero tool offset) and use touch off, leave the default setting of G54 on the pulldown, leave the default number of zero, and click OK
[15:55:23] <cradek> you'll see the readout go to Z=0
[15:56:37] <cradek> this moves Z of the default G54 coordinate system's origin to that point
[15:58:03] <Nick001> there's 8 tools to load into offsets and that's if I don't double or triple up the tools an a station. Isn't g54 one of the mill's work offsets?
[15:58:56] <cradek> don't confuse a work offset (origin of your workpiece) with a tool offset (each tool's difference in position compared to the reference tool)
[16:00:48] <cradek> you can also use touch off to set a tool offset, by selecting "tool" in the pulldown menu
[16:00:54] <Nick001> ok newer concepts from the old Hardinge stuff - I'll go giveit a try. BTW any info on separating the 90v power supply and GE servo amp from the rest of the Hardinge wiring?
[16:01:47] <cradek> I don't have any general info on that but maybe I could help with a more questions once you dig into it
[16:02:46] <Nick001> I'll have to put pics & schematics up on my site
[16:03:25] <cradek> oops I meant to type "more specific questions"
[16:04:59] <Nick001> pics says it better and easier to point out what needs to be separated
[16:45:17] <Danimal-office> selecting tool in a pulldown menu?
[16:49:36] <Danimal-office> hmm apparently i dont have that pulldown menu
[16:50:32] <cradek> it's in 2.3
[16:50:46] <cradek> on the touch off screen
[16:50:49] <Danimal-office> i have the newest versions
[16:51:08] <Danimal-office> i dont think i have a touch off screen
[16:51:14] <cradek> sure you do
[16:51:21] <cradek> it's what you get when you poke the touch off button
[16:51:40] <Danimal-office> didnt see one
[16:51:47] <Danimal-office> i'll go look
[16:51:50] <cradek> one what? the button?
[16:51:56] <cradek> I'm so confused
[16:53:04] <Danimal-office> all there is when i hit the touch off button is a dropdown menu with work offsets
[16:53:29] <cradek> if you have a tool loaded, you'll see the option to touch off the tool
[16:53:49] <cradek> maybe you didn't have a tool loaded
[16:54:06] <Danimal-office> hmm
[16:54:37] <Danimal-office> good to know, i hate having to go to the tool table all the time
[16:56:27] <Danimal-office> it changes the offset that's loaded, not the tool, right? so if i have t3 in the machine, but i'm using h32 with it, it'll change the h32, and not h3, right?
[16:57:11] <cradek> no
[16:57:28] <cradek> in that case it would change the entry for t3 in the tool table
[16:57:40] <Danimal-office> oh
[16:57:48] <Danimal-office> darn
[16:58:26] <Danimal-office> i used my lathe the other day for the first time
[16:58:31] <Danimal-office> worked pretty good
[17:01:14] <Danimal-office> i can see the manual lathe getting far less use
[17:01:29] <cradek> that's a good sign
[17:02:48] <Danimal-office> btw, i'll get your parts out today. got stuck with a hot job i had to get out faster than possible so i've been slacking on everything else
[17:03:08] <cradek> there is no hurry - whenever you have time.
[17:03:28] <Danimal-office> the job is finally done, thank god. at least this run, still got a ton more
[17:04:01] <Danimal-office> i gotta ship some stuff today so i'll get it done with the rest
[17:04:32] <Danimal-office> i think i'm gunna pick up another one of those vfd's for my mill's coolant pump
[17:06:01] <Danimal-office> i have an idea.... the coolant tank is in the base of the machine, so it's cast iron and rusts like crazy... i'm going to add an external coolant tank, and have the coolant pumped out of the internal tank and into the external tank as the machine runs
[17:06:39] <cradek> you can't drain directly into the external tank?
[17:06:41] <Danimal-office> because it's impossible to catch all the coolant before it gets into the machine's tank
[17:07:00] <cradek> yuck
[17:07:02] <Danimal-office> i can, but it'll still get some in the base
[17:07:15] <cradek> I love the coolant setup on my mori
[17:07:28] <Danimal-office> it splashes over the side of my enclosure quite often
[17:07:36] <cradek> it's all external and based on huge holes in the table you could throw a brick through
[17:07:47] <Danimal-office> yea, those are nice
[17:07:55] <cradek> it never plugs and coolant always flows into the tank
[17:08:26] <Danimal-office> we had one of those in the toolroom in one of the places i worked back east
[17:09:08] <SWPadnos> so nice to be back east
[17:09:20] <Danimal-office> never used it though, it was sort of the other toolmaker's mill. he had his, and i had mine
[17:10:10] <Danimal-office> mine was a mitsubishi with some crappy windows based controller. it sucked
[17:10:20] <Danimal-office> no g codes, all conversational
[17:10:44] <Danimal-office> SWPadnos: says who lol
[17:11:12] <SWPadnos> says me. I'm finally sitting in my own chair drinking my own coffee again
[17:12:08] <Danimal-office> last time i talked to my parents, my dad was raking snow off the roof
[17:12:29] <SWPadnos> oh, there was a little falling when the plane came in last night, but nothing to speak of here
[17:12:33] <SWPadnos> it is colder than LA though
[17:13:08] <Danimal-office> i think i would rather be in VT than LA though
[17:13:19] <SWPadnos> yep, most of the time :)
[17:13:28] <Danimal-office> LA is a bit crazy for me
[17:13:49] <SWPadnos> yep
[17:13:55] <Danimal-office> San DIego is a little more laid back
[17:14:06] <Danimal-office> depending on where you are
[17:14:11] <SWPadnos> the strange thing is it took us less time to drive from downtown to LAX than it did to wait in the security line at LAX
[17:14:28] <Danimal-office> ha
[17:14:31] <SWPadnos> usually it takes hours to drive anywhere
[17:14:44] <Jymmm> Nah
[17:14:49] <SWPadnos> in LA
[17:14:59] <Jymmm> You just have to knw where to drive
[17:15:18] <Danimal-office> i avoid LA like the plague
[17:15:18] <SWPadnos> yeah, don't
[17:15:22] <Danimal-office> lol
[17:15:47] <SWPadnos> luckily, there was a great sushi restaurant across the street from the hotel
[17:15:57] <Jymmm> lol
[17:16:23] <Danimal-office> however, the last time i went to VT, a huge hole in the road almost swallowed my buick
[17:16:30] <Danimal-office> litterally
[17:16:45] <SWPadnos> heh
[17:17:04] <SWPadnos> way back when, there was a guy called the "pothole bandit"
[17:17:06] <Jymmm> Yeah, lets bombs VT
[17:17:19] <SWPadnos> he'd go around planting trees in the potholes in Burlington
[17:17:24] <Danimal-office> hahha
[17:17:25] <Jymmm> lol
[17:17:29] <Danimal-office> this was in burlington!!
[17:17:40] <Jymmm> That gets the point across I gess
[17:17:43] <SWPadnos> were you here ~20 years ago? :)
[17:17:57] <Danimal-office> ha, i was 8 20 years ago
[17:18:13] <SWPadnos> well, an ambulance broke an axle in a pothole, so he decided to make them more noticeable
[17:18:16] <SWPadnos> heh
[17:18:34] <Danimal-office> i tell you what though, the dmv in VT had the shortest line ever
[17:18:46] <Danimal-office> in fact i was first AND last in line
[17:18:57] <SWPadnos> it varies, but I haven't waited more than 10 minutes in the last 10 years or so
[17:19:50] <Danimal-office> nice
[17:20:10] <Danimal-office> and i believe VT has a pretty bitchin machinery museum
[17:20:22] <Jymmm> SPARTACUS (2010) on netflix is AWESOME!!!
[17:20:41] <Danimal-office> Jymmm: watch instantly?
[17:20:47] <Jymmm> yeah
[17:20:51] <Danimal-office> sweet
[17:20:55] <Jymmm> it's a series
[17:20:59] <Danimal-office> oh
[17:21:14] <Jymmm> three episodes are up there
[17:21:36] <SWPadnos> oh ywah, in Springfield
[17:21:38] <SWPadnos> yeah
[17:22:03] <SWPadnos> apparently Springfield used to be the ball bearing capitol of the world or something
[17:22:19] <Jymmm> and bart simpson
[17:22:36] <SWPadnos> yes, they did select our Springfield as *the* springfield
[17:22:49] <Danimal-office> did they?
[17:22:55] <SWPadnos> after all, we have an aging nuclear plant nearby :)
[17:22:56] <SWPadnos> yep
[17:23:04] <Danimal-office> congrats!
[17:23:06] <SWPadnos> the premiere of the Simpsons movie was there
[17:23:07] <Jymmm> SWPadnos: Ya know... you CAN eat like Homer
[17:23:09] <SWPadnos> or something
[17:23:14] <SWPadnos> mmmmm. donuts
[17:23:25] <Jymmm> SWPadnos aka Homer
[17:23:32] <SWPadnos> but I moved away from Springfield 35 years ago
[17:24:06] <Jymmm> You can take the Homer out of Springfield, but not out of the donut shop!
[17:27:02] <Jymmm> They WAY OVER embelish the blood - the FX guys must of had a field day on a the blood packs
[17:27:07] <Danimal-office> it's all ball bearings these days
[17:27:13] <Danimal-office> and 30 weight motor oil
[17:28:31] <Danimal-office> i watched a couple dirty harry movies the other day... they have come a long way in in the department of fake blood
[17:29:07] <Danimal-office> looked like they just shot clint with a paintball gun
[17:29:17] <Danimal-office> it looked more orange than red
[17:30:04] <Danimal-office> damn, already 9:30. guess i should get some work done
[19:34:31] <alex_joni> here's a nice machine http://www.apexauctions.com/auction/lotForAuction.htm?lotId=36281&utm_source=IMS&utm_medium=Email&utm_campaign=Hauni%20Machinetools%20US
[19:40:39] <archivist> wont fit in the house !
[19:40:50] <alex_joni> build a bigger one :)
[19:41:10] <frallzor> that machine can mill you a new one
[19:45:01] <renesis> guys
[19:45:15] <renesis> atom mobos, ok for realtime?
[19:46:32] <skunkworks_> decently consistant... from my experience. (using the stock emc install - just a but under 20us jitter)
[19:47:24] <renesis> hmm
[19:47:40] <renesis> thats about the same as my sempron thing
[19:49:16] <skunkworks_> kim!
[19:50:27] <frallzor> anyone doing an interesting build and got a nice log? =)
[20:48:49] <andypugh> Does Gantrykins actually do anything useful at the moment? I can see that in the future it might be handy in a schema where each joint exports a motor-posn-cmd etc and has its own limit switch inputs, but I don't think that is the case now?
[20:49:58] <frallzor> ohh a new geckodrive
[20:50:18] <andypugh> Aye, I got that sticky-footed spam too.
[20:51:34] <andypugh> And ignore that Gantrykins comment, I think I might have been missing something
[20:52:17] <frallzor> bloody snow
[20:52:28] <WalterN> generally snow is white
[20:53:07] <andypugh> I was definitely missing something. I see that the axis gui now uses joints..
[21:01:20] <danimal_garage> WalterN: sometimes yellow
[21:01:36] <danimal_garage> but Frank Zappa would advise you not to eat it
[21:01:40] <archivist> naughty
[21:03:28] <danimal_garage> ugh this working crap is for the birds
[21:06:47] <WalterN> lol
[21:06:54] <WalterN> you dont like playing with plastic?
[21:08:45] <danimal_garage> ehh
[21:08:57] <danimal_garage> makes a damn fluffy mess
[21:09:20] <WalterN> I thought that was the fun part
[21:09:27] <WalterN> aside from the smell
[21:09:37] <danimal_garage> not when your shop is in a 2 car garage
[21:10:10] <WalterN> with the cars?
[21:10:18] <danimal_garage> HA!
[21:10:26] <WalterN> :-P
[21:10:33] <danimal_garage> not with 12 tons of iron in here
[21:10:40] <andypugh> Better than glowing-red lumps of steel.
[21:10:58] <danimal_garage> andypugh: if they're red, you're doing something wrong
[21:11:12] <andypugh> Or using CBN tooling :-)
[21:11:26] <archivist> friction welding :)
[21:11:50] <danimal_garage> i'm talking about regular milling and turning, smartasses lol
[21:12:04] <danimal_garage> obviously a foundry will be a different story
[21:12:18] <andypugh> I have some CBN tools for machining ballscrews. The salesman said that if the chips were not coming off as sparks, my spindle speed was too low. He opined that the process was best seen as single-point grinding.
[21:13:12] <danimal_garage> at least i got these guys to revise their parts after they saw my bill
[21:17:48] <tom3p> wow you didnt have a cost in before?
[21:18:13] <danimal_garage> i gave them a ballpark
[21:18:25] <tom3p> and how'd they turn out? was the wall a problem?
[21:18:27] <danimal_garage> i was within the ballpark
[21:18:38] <danimal_garage> they came out decent
[21:18:58] <tom3p> great, doing more by removal or going onto the mold?
[21:19:23] <danimal_garage> i gotta do at least 56 more by machining
[21:19:38] <danimal_garage> and then we discuss the mold
[21:19:57] <danimal_garage> but they revised the part so i can eliminate some ops
[21:20:18] <tom3p> sounds like you had hairballs on some cuts "damn fluffy mess"
[21:20:45] <danimal_garage> yea, on some lathe ops
[21:20:49] <tom3p> so you must've kept the cutter honed sharp
[21:21:02] <danimal_garage> just used off the shelf inserts
[21:21:10] <tom3p> nice going, good to hear monetary success storeis with emc2
[21:21:37] <danimal_garage> thanks! i actually make a living with my machines
[21:21:57] <danimal_garage> so emc has been very helpful
[21:22:14] <danimal_garage> glad i went with emc rather than mach
[21:23:07] <danimal_garage> i just cant see them working as well as they do with mach
[21:24:05] <danimal_garage> and i cant see them working as well as they do without this channel
[21:27:56] <danimal_garage> hmm so i got 2 enclosures i can use for my mill's pc... one is 6x16x27 and the other is 11x16x20. the second one is in better shape. wonder what one i should use for my pc, relays, mesa boards, etc
[21:28:19] <danimal_garage> anyone have any thoughts?
[21:28:53] <danimal_garage> either will work for now, i'm thinking for down the road when i may add something to it
[21:29:02] <danimal_garage> not sure what that something would be though
[21:31:09] <alex_joni> dragons
[21:31:10] <andypugh> Go for the biggest one, it will still be too small :-)
[21:33:06] <danimal_garage> bigger in cubic feet, or bigger in footprint? the shoter deeper one is actually bigger in cubic feet
[21:33:19] <danimal_garage> that's my dillema
[21:33:23] <andypugh> Mine will be about the same size as your bigger one (it is basically 5U, a 1U server as the PC, a 2U box for the interfaces, wiring, drivers and power supplies and 2U for the VFD, filters and assosciated relays.
[21:33:35] <tom3p> put everything on a plate that can be removed and put back, make all the wiring AWAY from the edges so you can get your meathooks in there
[21:33:56] <frallzor> fuck snow =(
[21:34:07] <tom3p> does not sound like fun
[21:34:11] <andypugh> No, that would be silly.
[21:34:23] <danimal_garage> it's like 70 here lol
[21:34:42] <andypugh> Centigrade?
[21:34:46] <danimal_garage> i better stop saying that before noone helps me
[21:34:48] <frallzor> http://www.youtube.com/watch?v=1gh558Q3uSU
[21:35:04] <danimal_garage> yes, centigrade... i'm in the firey depths of hell
[21:35:29] <alex_joni> u deserved it, probably
[21:35:33] <tom3p> :) i got pic pwm down into the nS range (heh and very good latency haha)
[21:35:41] <danimal_garage> ha
[21:36:02] <alex_joni> ;)
[21:42:09] <danimal_garage> i'd like to get a smaller bare-bones mobo
[21:42:19] <danimal_garage> for both the lathe and mill
[21:44:08] <danimal_garage> how do you guys keep your boards secure when you're not using a computer case?
[21:44:21] <danimal_garage> like pci baords and whatnot?
[21:45:45] <ries> frallzor: Delta lloyd makes a lot of these advertisements... they are really good
[21:48:07] <frallzor> I see
[21:50:46] <KimK> Hi all. John has a US Digital encoder card and I am trying to help him make use of it. I have it installed in my system and am seeking help and advice. Here's a link to more info: http://www.pastebin.ca/1776257 Thanks in advance for any help or advice.
[21:51:37] <frallzor> bloody snow will slow my build down =(
[21:52:27] <alex_joni> KimK: it seems you'll have to take their driver and make a new one based on it
[21:53:13] <alex_joni> a emc2 HAL driver I mean
[21:53:34] <KimK> alex_joni: because of the RTAI business?
[21:53:36] <alex_joni> but before blindly copying, adapting, you'll have to check their licensing too
[21:53:43] <alex_joni> because that's how emc2 works
[21:53:56] <alex_joni> it doesn't use linux drivers.. different domain
[21:54:14] <alex_joni> imagine there are actually 2 different PCs inside your computer
[21:54:20] <alex_joni> one is running linux
[21:54:27] <alex_joni> the other one is running RTAI/realtime
[21:54:52] <alex_joni> now you put in the card.. with their drivers linux sees it, but emc2 doesn't
[21:55:13] <alex_joni> with the emc2 HAL driver (which needs to be written, adapted) emc2 sees it, but linux doesn't
[21:56:49] <cradek> mesa 7i43p is $79 qty1 and will give you up to 12?? encoder inputs, already fully supported by the emc2 drivers
[21:58:34] <andypugh> And if you don't want 12 encoders, you can have PWMs, Stepgens, GPIO instead
[21:58:38] <alex_joni> you'll certainly spend more than 80$ for a new driver
[21:58:47] <tom3p> logger_emc bookmark:
[21:59:06] <KimK> John says this one was $15 (instead of $350 new list) and doesn't need another parallel port, LOL
[21:59:07] <tom3p> logger_emc: bookmark
[21:59:10] <alex_joni> logger_emc: bookmark
[21:59:10] <alex_joni> Just this once .. here's the log: http://www.linuxcnc.org/irc/irc.freenode.net:6667/emc/2010-02-02.txt
[21:59:24] <tom3p> ?
[21:59:50] <alex_joni> tom3p: you got some strange extra chars in there
[22:00:11] <tom3p> i cant see 'em, people have said that before....
[22:01:17] <cradek> er maybe you can only get 8 encoders per 7i43 with our firmwares (but you get 8 pwm/dir for servos too)
[22:02:15] <cradek> there's also a 4 encoder, 4 pwm/dir, 4 stepper firmware
[22:02:21] <KimK> This might be a lot of work, but I would like to try it. I need to learn more about this end of things.
[22:02:38] <tom3p> alex your explanation of 2 pcs was worth dog-ear- ing
[22:03:13] <cradek> KimK: (if you can get decent documentation a driver for basic functionality might not be very hard.)
[22:05:50] <KimK> We have US Digital's link to a 158kB tar.gz file at: http://www.usdigital.com/download/86 I will need plenty of help and advice. cradek, are you up for a visit sometime? (Don't worry, I'm in Minneapolis right now;)
[22:07:33] <cradek> KimK: wish you could have come this weekend - we had a lot of fun working on the bridgeport retrofit and several other projects
[22:08:15] <KimK> I caught a little about it on IRC earlier, saw some of the pictures. Where was your mini-fest?
[22:08:49] <cradek> it was in my shop and garage
[22:08:53] <alex_joni> pictures? I missed those
[22:08:56] <cradek> there are pictures?
[22:09:30] <KimK> Not sure, maybe they were sam's skunkworks project?
[22:09:32] <alex_joni> cradek: big brother is watching you
[22:09:46] <cradek> ah, could be. separate event :-)
[22:10:00] <alex_joni> or was it squirt watching?
[22:10:21] <cradek> I wish we had taken pictures of the bridgeport retrofit, but we didn't take the time
[22:10:42] <alex_joni> seb gets the job to take pictures of it working at least
[22:10:56] <KimK> John and I have talked about visiting Sam and his Dad sometime, but nothing definite yet.
[22:11:20] <KimK> John asks what kind of Bridgeport is it?
[22:11:26] <cradek> yep, seems like you are pretty close to him. are you guys coming to cnc workshop in ann arbor?
[22:11:33] <cradek> it's a series 1 servo machine, r2e3
[22:11:34] <skunkworks_> http://www.electronicsam.com/images/KandT/conversion/xaxis/
[22:12:10] <danimal_garage> cradek: i'm trying to arrange some way to get out there
[22:12:21] <cradek> we did the retrofit saturday :-)
[22:12:34] <cradek> well it went into sunday, but just a bit
[22:13:12] <KimK> cradek: yes, in 11.25 hours, I read, congratulations.
[22:14:04] <seb_kuzminsky> cradek, andypugh: the 7i43 supports only 8 encoder channels, not 12
[22:14:05] <danimal_garage> u did a retrofit in 11 hours??
[22:14:18] <danimal_garage> impressive
[22:14:20] <cradek> nope, it took 11:15
[22:14:37] <seb_kuzminsky> oh right, you already said that
[22:14:46] <danimal_garage> took me over a month for the hardinge lol
[22:14:51] <andypugh> All numbers bigger than 5 look the same to me. :-)
[22:14:52] <cradek> well we were making chips at 11:15, we tuned servos a little more the next morning
[22:15:08] <danimal_garage> nice
[22:15:38] <cradek> then we engraved an EMC2 AXIS logo and called it done
[22:15:47] <seb_kuzminsky> heh
[22:15:56] <seb_kuzminsky> still gotta figure out why the Z servo is running so hot
[22:16:14] <cradek> yeah it's a bit grumbly
[22:16:47] <KimK> John's next Bridgeport project (the one he got from Terry in Sioux City, IA) is a Series II r2e3, so it's about 6500 lbs(?), a little bigger than a Series I.
[22:17:31] <cradek> neat - sounds familiar.
[22:17:44] <cradek> hope it goes as easy as ours did.
[22:18:13] <cradek> he will like a servo machine a lot better :-)
[22:20:59] <andypugh> I am having a bit of fun messing about with configs on my VM. I have set up a machine using Gantrykins, and it gangs the 1 and 3 joints together neatly as expected. (and switches from X,Y,Z to joints 1,2,3 in the Axis gui too, which is rather nice. However, I would expect 4 joints for a 4-motor setup? Jogging Joint 1 only moves the Axis.1.motor-posn-cmd, (which is fine) but there is no checkbox to choose joint 3 to jog that.
[22:20:59] <andypugh> suspect I am missing something in the config files?
[22:21:15] <andypugh> Is "JOINTS = 4" a valid entry in the INI?
[22:22:13] <KimK> John says "not!" (as easy as your). And John already is liking servos better than steppers, but his 2nd Bridgeport will be steppers too, due to availability. Three-phase steppers and drives already in hand (1500 in-oz!). This one has lots of mechanical issues to deal with first. Oiling system probably plugged, needs adapters to accept 3-phase stepper motors, lots of cleanup, etc.
[22:23:12] <danimal_garage> sounds like the same size as my shizuoka
[22:24:22] <andypugh> OK, the answer is "Yes". Sorry for being too lazy to spend the 10 seconds finding out.
[22:27:49] <KimK> It's about that size, but no tool changer. It does have qwick-switch 300 though. (Similar to MTB30 with lugs). I'm also almost done with a Kasuga retrofit and that's very similar to a Shizuoka, I think both originally came with a Bandit control and a Dana/Summit tool changer.
[22:33:03] <skunkworks_> KimK: need to cnc? http://www.youtube.com/watch?v=2fUcCoj7APQ
[22:33:04] <skunkworks_> ;)
[22:47:11] <KimK> Thanks Sam, nice pictures, John and I look forward to seeing it in person sometime.
[22:47:42] <KimK> cradek: did you happen to look at that US Digital tar.gz and is that anything that could serve as a starting point?
[22:51:25] <ries_> ries_ is now known as ries
[22:52:21] <andypugh> Bah! There is one huge drawback with IRC, if you find an elegant answer to somebodies question when they are offline, there isn't much you can do about contacting them.
[22:53:22] <Eric_K> that's what they all say
[22:55:06] <tom3p> "cnc workshop in ann arbor" is there some announcement?
[22:56:27] <skunkworks_> http://bbs.homeshopmachinist.net/showthread.php?t=36635
[22:57:49] <tom3p> thx i thought emc2 wkshop, thats a 'Digital Machinist CNC Workshop' which is also nice
[22:57:52] <KimK> andypugh: That's why I usually leave IRC online when I can. I often don't even bother to add _afk, which I suppose is bad form. But I too prefer leaving the channel open.
[22:57:52] <Eric_K> Roland give up on the idea?
[22:59:18] <tom3p> oh i see RayH is giving a lecture, so it >is< emc2 also
[23:00:12] <KimK> Sorry, forgot to answer the Q on 2010 CNC workshop earlier. John is still thinking it over. I'm probably going to go, unless I can't for some reason.
[23:00:18] <tom3p> i dunno, i dont think to use homeshopmachinist as first srource for info on emc2
[23:05:02] <andypugh> That's likely to confuse Bevins (who I tracked down via the YouTube video he posted)
[23:09:23] <andypugh> Is there any sort of emblem that represents "Open Source" in general in the same way as Tux does Linux?
[23:11:22] <andypugh> It seems there is, but I have never seen it. http://www.opensource.org/logo-usage-guidelines
[23:11:30] <archivist> I should bring my bot in, it has a !later nick message

[23:29:43] <tom3p> andypugh: ^^^
[23:30:48] <andypugh> Thanks tom3p
[23:48:54] <tom3p> damn! " Attendee cost:$125 – before March 1, 2010" now i know how to make money in cnc
[23:51:03] <andypugh> I wonder if home-made shring-fit holders would succeed?
[23:51:09] <andypugh> (shrink-fit)
[23:51:09] <tom3p> for anyone going, also proud lake recreation area is pretty close & camping is cheap ( plus 30 amp connection) other local provate campgrounds have wifi & ~ 30$/pop
[23:51:24] <tom3p> got the heater?
[23:51:44] <andypugh> Got a blowtorch.
[23:51:48] <tom3p> heh
[23:52:53] <andypugh> I was thinking about a set of drills in Tormach-style holders with their lenghts tool-tabled.
[23:53:26] <tom3p> setting tool length away from machine?
[23:53:41] <tom3p> (like a setter station)
[23:53:44] <andypugh> Though I guess a lot of ER16 collets wouldn't be a lot more work to make. (in fact, probably easier)
[23:54:06] <andypugh> No, just lengths that don't change the way they do in a chuck.
[23:54:32] <tom3p> hmm the emc thomas deckel cutter grinder tool setter
[23:55:15] <tom3p> i think the sons name was thomas
[23:55:41] <tom3p> the old man mad eth emachine tools, the son made the cutter grinder
[23:56:11] <Eric_K> OT: GE shipped me a stove that didn't have all the parts, now they can't figure out how to get me the parts.
[23:56:34] <tom3p> they come in a new stove ;)
[23:56:45] <Eric_K> or not
[23:57:03] <Eric_K> thinking about just taking it back and letting sears figure it out
[23:57:20] <tom3p> hmm, >you< can become the parts house (except for #127b )
[23:57:46] <Eric_K> for whatever reason, companies have gotten away from listing the part numbers for anything
[23:57:55] <Eric_K> makes getting parts nearly impossible
[23:58:24] <Eric_K> had that problem with Pella on a door. "I need the little plastic doojerwhacky that holds the screen in the track"
[23:58:50] <andypugh> Dagnabbit! My dad had one of those Deckel cutter-grinders. We could never find a use for it, and scrapped it..
[23:59:18] <andypugh> Now I see them on eBay for thousands.
[23:59:45] <Eric_K> I'm going to need the tourette's support group in a minute
