[03:29:16] <atex57> rayh: Has anyone been reccording your classes? I can't get there till Thur evening and wanted to hear your stuff.
[04:07:44] <JymmmEMC> JymmmEMC is now known as MrAsshole
[04:09:32] <MrAsshole> MrAsshole is now known as JymmmEMC
[06:36:18] <reychan> hallo :)
[06:36:58] <reychan> i have one little problem with emc2, please help!
[06:38:33] <fenn> please state the nature of the problem
[07:05:51] <ds2> EMC == Emergency Machine Controller? :)
[08:26:28] <archivist> * archivist reads survey results wish it was easier to find31.91% more links!! for google to find
[08:53:43] <dimas_> hi all
[08:55:47] <dimas_> are there 8-phase stepper motors is use nowadays?
[08:55:54] <dimas_> in use
[09:03:21] <Sweeper> dimas_: somewhere, probably...
[09:07:00] <dimas_> is it oblosete solution? is there 8-phase stepper driver or 8-phase mode in available drivers?
[09:07:57] <archivist> there is microstep in most modern drivers for normal stepper motors
[09:10:05] <dimas_> I think it's not only microstep but 8-wire motors that may be unusual today
[09:10:14] <dimas_> am I right?
[09:12:53] <archivist> I have motors with 8 wires, I dont call them 8 phase
[09:15:20] <archivist> coils are in pairs and can be series or parallel connected
[09:15:53] <dimas_> great
[09:16:05] <dimas_> what your motors are?
[09:21:12] <archivist> http://www.arceurotrade.co.uk/Catalogue/Stepper-Motors second one down
[09:21:49] <archivist> download data for connection details
[09:22:57] <dimas_> thanks, and I will check agiecut's schematics later today
[11:00:42] <acemi_> acemi_ is now known as acemi
[11:20:45] <rayh> Hi atex57 sorry I missed your question. No we were not able to get recording.
[11:21:45] <alex_joni> hey rayh
[11:21:52] <rayh> Hi Alex.
[11:22:05] <alex_joni> hope all is well on your end :)
[11:22:17] <rayh> Yep. Doing great.
[11:22:38] <alex_joni> great
[11:22:55] <rayh> I hear that the tooling is arriving today so that Roland can make his motor mounts.
[11:23:18] <rayh> cradek has been working on the gcode
[11:24:05] <rayh> SWPadnos got EMC2 talking to a frequency drive using modbus yesterday.
[11:24:51] <rayh> It was great to see it running a program and spinning the spindle using serial.
[11:25:47] <alex_joni> cool
[11:25:57] <alex_joni> the modbus stuff sounds nice
[11:28:06] <rayh> Yep. I've already got a project for it.
[11:28:17] <Sweeper> so what's a good way to talk to embedded devices over 300'ish distances? preferably using cat5?
[11:28:54] <rayh> The lab with Steve's PMDX-112 is really awesome for learning HAL.
[11:29:56] <rayh> Sweeper, Does this need to be real time?
[11:30:11] <Sweeper> rayh: not really
[11:30:17] <alex_joni> Sweeper: ethernet probably
[11:30:22] <alex_joni> either copper or fiber
[11:30:34] <rayh> Good.
[11:30:39] <Sweeper> gah. ethernet modules are spendy D:
[11:30:47] <rayh> bbiab.
[11:30:48] <alex_joni> Sweeper: two cans on a string?
[11:30:52] <Sweeper> and also complicated to talk to :v
[11:31:14] <BigJohnT> that's what I use
[11:31:15] <Sweeper> I was hoping there was some nice bus protocol I could use
[11:32:01] <alex_joni> maybe rs485..
[11:33:18] <Sweeper> oh yes....
[11:33:25] <Sweeper> 100kbits at 1200 is plenty
[11:34:16] <Sweeper> that's 1200 METERS
[11:34:23] <Sweeper> pretty :3
[11:37:14] <alex_joni> you only need a voltage shifter
[11:37:24] <alex_joni> most micros have a serial port
[11:39:27] <Sweeper> yea
[11:39:50] <Sweeper> I think I shall use it for home monitoring/automation
[11:41:00] <alex_joni> there are some existing protocols for that
[11:41:06] <alex_joni> usefull if you need existing sensors
[11:42:03] <alex_joni> don't remember the name though..
[11:42:04] <Sweeper> eh, I'll be haxing my own
[11:42:09] <alex_joni> x-something
[11:42:09] <Sweeper> modbus runs over it
[11:42:24] <BigJohnT> x10
[11:42:39] <Sweeper> I got this awsome pdf about making your own sensor packages
[11:50:22] <BigJohnT> link?
[11:55:19] <alex_joni> http://www.parkwayreststop.com/archives/2714 <- whee
[12:06:58] <BigJohnT> YEA! SheetCam works on 6.06 now
[12:07:27] <alex_joni> nice
[12:08:15] <BigJohnT> bbl time to slop the hogs and walk the dog
[12:08:21] <skunkworks> morning alex.
[12:08:27] <skunkworks> trip day today.
[12:08:43] <skunkworks> might have to ford a few rivers ;)
[12:09:55] <archivist> where a gps comes in useful, find new route when blocked
[12:10:25] <skunkworks> oh - it is already in the truck :)
[12:11:48] <archivist> I first used one driving in France around striking truck driver roadblocks
[12:12:33] <jepler> a gps can find a different route, but won't know if it's blocked
[12:14:42] <archivist> true
[12:14:46] <als> take the boat down the lake
[12:21:07] <skunkworks> yes - but it is easy to find other routes to get there.. I am sure dad will update the maps right before we go.
[12:25:26] <atex57> Skunkworks: Are you going down 61 to the Quad Cities?
[12:27:15] <skunkworks> we nomrally take 61 thru dubuque and davenport
[12:28:45] <skunkworks> actually - we may take 35 down (I don't know if we have decided)
[12:29:08] <skunkworks> that ends up in debuque also
[12:30:35] <atex57> 61 is a simpler route. Holler if you see road problems. I will be taking 61 down tommorow.
[13:15:38] <cradek> skunkworks: don't forget to bring water
[13:18:30] <skunkworks> cradek: that is on the list. Thanks :)
[13:19:02] <cradek> you're coming tonight?
[13:19:55] <cradek> bonk
[13:20:25] <alex_joni> so he said
[13:22:51] <cradek> good morning alex
[13:23:21] <cradek> we are keeping a list of task bugs for you to fix when you get back.
[13:23:30] <cradek> :-)
[13:24:20] <skunkworks> cradek: yes. we should be leaving this afternoon
[13:24:53] <skunkworks> anything we might have - you guys might need?
[13:25:10] <skunkworks> (I will be keeping tabs on here until we leave)
[13:26:29] <alex_joni> cradek: cool
[13:26:37] <cradek> I would have asked for a 4-48 die the other day, but then I realized I have a lathe
[13:26:55] <skunkworks> heh
[13:27:00] <cradek> alex_joni: I was joking actually
[13:27:22] <alex_joni> oh, even better :)
[13:27:26] <skunkworks> bbl
[13:27:45] <cradek> but if you feel like fixing some task bugs, let us know
[13:28:09] <alex_joni> well.. depends on what you consider a bug
[13:28:32] <alex_joni> if you say task concept is a bug, and it should be reorganized.. then I might not feel like fixing it :D
[13:30:37] <cradek> yuck, I see that nobody has filed a bug report for the one we were talking about - using resume from line doesn't turn the spindle on [and maybe doesn't do other things like turn on coolant]
[13:40:32] <renesis> omg
[13:40:56] <renesis> guys, boss guy has magically forgot the agreed up price range we talked about at 1st interview
[13:41:19] <renesis> so for first paycheck, CAD design, CAM programming, CNC operation, $150K holz-her router thing
[13:41:23] <renesis> $10/hr
[13:41:53] <renesis> cuz he also forgot when i said 'yeah no way i would have taken that other job if the money mattered at that point in my life'
[13:42:21] <renesis> paid last guy $18/hr
[13:42:35] <renesis> and i have to do 3 hours a bus a day to get there and back
[13:42:58] <renesis> jezus fuck if i wanted quicky-mart wages i would have found a closer job
[13:43:08] <renesis> so i talked to him about it yesterday in the morning
[13:44:00] <renesis> and hes like ill tell you whats up in an hour, said something in between $12-13, which i wont stay for, because thats not really fair for just CNC operation alone =(
[13:44:12] <renesis> so yeah no word all day yesterday, even tho we talked all day
[13:44:29] <renesis> they almost have no clue whats up with that machine, either, heh
[13:45:06] <renesis> they post to machine and post to file, when they output from CAM program
[13:45:31] <renesis> but then they close out the serial terminal editor, before doing ANYTHING rs232 related
[13:46:00] <renesis> because whats actually going on is theyre saving the files to the machine on an networked drive
[13:46:04] <renesis> not archiving them
[13:46:57] <renesis> when i saved the file to my work directory for backup, it fucked shit up because next time they tried to post to the machine theyre like WHY DIDNT THE FILES POST
[13:47:27] <renesis> all their files posted to my project working directory
[13:49:19] <archivist> sounds like a boss as well clued to wage rates as here
[13:49:49] <renesis> i had an electronics QA tech job for $10/hr
[13:49:52] <renesis> when i was in school
[13:50:16] <renesis> because money didnt matter to me i wanted to learn how this guy ran his test lab/little warehouse
[13:50:26] <renesis> so he thought he could pay me that
[13:50:36] <renesis> 1st interview, him: so how much?
[13:50:46] <renesis> me: low/mid 20s?
[13:50:58] <renesis> him: perfect
[13:51:40] <renesis> AND THEN we had a dialog, maybe 3 or 4 minutes, about how people come in asking for like $14 or $15 and hes like 'but thats insane, thats not enough!'
[13:52:42] <renesis> shady mfkr, if i stay its for $15 with agreed up raise schedule to im at his old guys rates, mostly because everyone else in the company seems cool, and even bossguy is cool except for this
[13:52:46] <renesis> anyway, grrr, etc
[13:56:46] <renesis> o
[13:57:15] <renesis> is it normal to MDI M6T# and for the machine not to load the tool length offset?
[13:57:27] <renesis> i had to be like D# to get it to load those
[13:57:49] <renesis> i dont think the has or bridgeport or fadal things were like that, but i dont think i did a ton of MDI
[13:58:13] <renesis> im pretty sure you didnt write the gcode for them like that
[13:58:47] <renesis> and i think S word went on the spindle enable block
[14:02:43] <renesis> anyway, this NUM Trace controller shit is horrible, i miss emc on my fairy mill at home
[17:31:34] <skunkworks> uh - a ladder...
[17:44:41] <fusion_crank> Hello
[17:45:39] <fusion_crank> does anyone have any experience with Smithy's EZ-Trol
[17:46:39] <SWPLinux> I think the guy who wrote it is here
[17:47:15] <fusion_crank> It looks great. Is it open source?
[17:47:27] <jepler> not as far as I Know
[17:47:39] <fusion_crank> It looks mach-like,
[17:47:46] <SWPLinux> bummer
[17:47:54] <fusion_crank> rats
[17:48:57] <fusion_crank> it has the 2 things that are missing from EMC from my point of view, conversational and lager dro's
[17:49:14] <fusion_crank> larger dro's that is
[17:49:37] <fusion_crank> beer dro
[17:49:47] <fusion_crank> s would be good too
[17:51:36] <SWPLinux> hang on, someone who knows is on the way
[17:51:55] <SWPLinux> EMC2 has come conversational stuff in development
[17:52:03] <SWPLinux> sonme
[17:52:03] <SWPLinux> some
[17:52:03] <SWPLinux> argh
[17:52:16] <SWPLinux> fusion_crank, meet mshaver
[17:52:26] <SWPLinux> mshaver, meet fusion_crank :)
[17:52:31] <fusion_crank> glad to meet you
[17:52:49] <SWPLinux> he may be able to answer your question(s)
[17:53:05] <fusion_crank> I hope so
[17:53:41] <mshaver> I hope so too!
[17:54:00] <mshaver> what did you want to know?
[17:54:39] <fusion_crank> I am looking for the EZ-Trol modification of EMC2
[17:54:58] <fusion_crank> I like the larger DRO's and conversational programing
[17:55:14] <mshaver> It's available from Smithy when you buy their system
[17:56:06] <fusion_crank> there-in lies the problem, I already have a system, I just want to buy the software
[17:57:43] <mshaver> I think that you should call sales at (800)476-4849. Ask for Kerry. I don't think we've sold just the software before, but I don't know why they wouldn't. Of course I'm not in sales...
[17:58:52] <fusion_crank> I have a call in to them, I don't know if I spoke to Kerry. I am waiting on a return call. I was doing my homework in the mean time.
[17:59:14] <fusion_crank> I hope the price isn't too high
[17:59:21] <fusion_crank> It looks great
[17:59:36] <mshaver> I'll call them & tell them to wake up & call you back! Can I reference a name?
[17:59:47] <fusion_crank> Mike Johnson
[18:00:14] <fusion_crank> thank you for your help
[18:00:32] <mshaver> I'll call now. If you have any other questions after you get it, I can answer them, or connect you with the programmer who knows all.
[18:00:38] <skunkworks> mshaver: is smity there?
[18:00:40] <mshaver> You're welcome!
[18:00:49] <skunkworks> *smithy
[18:00:50] <fusion_crank> Awsome!
[18:01:23] <mshaver> Yes, sort of. We didn't bring any machines to exhibit, but several folks are here to soak up the atmosphere ;)
[18:01:37] <skunkworks> Cool :)
[18:08:00] <mshaver> ´╗┐fusion_crank: I just tried to call, but can't get thru on my cell. I'll send an e-mail to Kerry instead. If you don't hear back from them, fell free to call me at (443)789-4628.
[18:10:53] <fusion_crank> thanks!
[18:12:19] <fusion_crank> this intrwaweb thing is pretty cool, I'll bet it takes off some day
[18:37:04] <tomp> emc2 big dro http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?PyVCP
[18:37:44] <fusion_crank> thank you!
[18:42:51] <fusion_crank> This looks very interesting, but probably above my level of expertise. I'll have to study it at length.
[19:26:21] <fusion_crank> I have another question regarding the Shuttle Express. I asked this on CNC Zone and was told it can't be done. I'd like to interface the Shuttle express with EMC2. I use it with my demo if Mach3 and its great.
[19:27:20] <fusion_crank> I was told it can't work with EMC and that doesn't make sense to me. If it can be made to work with mach, it should be able to be made with EMC2. Why does the OS matter?
[19:30:15] <alex_joni> fusion_crank: surely it can be done, it all depends on how much effort you want to invest on it
[19:30:50] <alex_joni> as it is now, there is no simple connect and configure though
[19:30:57] <alex_joni> (for some reason that eludes my memory)
[19:31:03] <skunkworks> fusion_crank: I was the one that replied to you on cnczone. (samco)
[19:31:06] <skunkworks> bbl
[19:31:16] <alex_joni> safe trip samco
[19:31:19] <fusion_crank> thank you for the reply
[19:31:58] <fusion_crank> I wish I had the background to figure out such a problem
[19:32:45] <fusion_crank> it is such a slick tool for touching off a setup
[19:33:54] <awallin> fusion_crank: see here http://article.gmane.org/gmane.linux.distributions.emc.user/2112
[19:34:11] <fusion_crank> here is my problem with joy pads, you can move 2 axis at once, when I am touching off, I only want to move one.
[19:35:02] <fusion_crank> is there a way to make it so you have to hold a button to select an axis and then the direction at the same time to prevent the 2 axis move?
[19:36:39] <fusion_crank> I read that article, I wonder how Mach overcame this problem
[19:39:06] <awallin> conventional jog-wheels that output quadrature pulses work very well with emc2
[19:41:51] <fusion_crank> are there any tricks you use for touch-off and setups while using a joypad? I have one, but it just seemed odd and clumsy.
[20:02:46] <BigJohnT> fusion_crank: yes you can move only one axis at a time with a joypad as well as select the speed
[20:05:58] <fusion_crank> how do you move only one axis of you inadvertently push the joystick a little of 90 degree angles?
[20:08:21] <tomp> most joysticks are 'digital' (buttons under the stick) fewer are analog ( pots under the stick). the button type wont notice anything minor off '90 degrees'. the analog ones can be used by software that ignores small values.
[20:08:56] <tomp> both can be used by software that ignores other directions or only applies to one direction
[20:09:09] <fusion_crank> I use my mill to do cnc and manual machining. If I am cutting a groove in a part, I don't want the cut to wander. I only want to change axis when I intend to
[20:09:11] <tomp> dierection/axis
[20:10:07] <fusion_crank> so set a larger dead zone in the center?
[20:10:32] <tomp> disengage the cnc, use gib locks, just like on a real mill or get complicated
[20:11:15] <tomp> you could still have the dro while cranking
[20:11:15] <pjm_> archivist : btw i found a replacement IPM module in the UK for 30 quid brand new!
[20:11:26] <archivist> nice
[20:22:50] <anonimasu> if your cnc mill does wander when you do cutting you probably shouldnt mill with it..
[20:23:22] <anonimasu> * anonimasu has been there before :p
[20:23:36] <anonimasu> where axes got pulled out of position making the edges ~
[20:23:48] <anonimasu> ^_^
[20:23:59] <archivist> and me, stopped fixed column properly , restarted
[20:24:21] <anonimasu> I bought bigger servos :)
[20:24:33] <fusion_crank> no, by wander I mean I am cuting a groove in the x axis by pressing the x axis joystick and for a moment my thumb wanders up in the y just a bit and so does the mill
[20:25:01] <archivist> I was to keen to play, the column was just clamped to the base
[20:26:24] <anonimasu> :)
[20:35:40] <tomp> fusion_crank: if you want the cnc to mill the slot, just issue feeds and a G01 blah command. the cnc's just is to eliminate wandering or stop with an error
[20:36:44] <tomp> and, you can write software that only moves the one axis despite your thumb's errant ways
[20:37:13] <anonimasu> * anonimasu nods
[20:37:36] <anonimasu> jog is only good for setting up parts .)
[20:38:35] <fusion_crank> Oh, but it is so convienient for cutting too ;-)
[20:38:52] <fusion_crank> except for the wandering bit
[20:39:49] <archivist> I would only jog with a defined key that only moves what I want
[20:46:36] <BigJohnT> fusion_crank: sorry customers came in for a visit
[20:47:25] <BigJohnT> fusion_crank: use the two joysticks for X and Y and use buttons for Z
[20:47:55] <fusion_crank> ooo, I like that!
[20:48:23] <BigJohnT> as in my example on the wiki site use the speed buttons as the enable so if you move a stick nothing happens unless your finger is also on the speed button
[20:50:11] <fusion_crank> which wiki is that please?
[20:50:17] <BigJohnT> brb
[20:51:01] <BigJohnT> EMC wiki! step by step here http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Simple_Remote_Pendant
[20:51:39] <fusion_crank> thank you!
[20:51:43] <BigJohnT> np
[20:51:50] <BigJohnT> * BigJohnT goes back to work
[20:56:54] <fusion_crank> Thank you all for your help. Gota go! Bye.
[20:58:36] <BigJohnT> anonimasu: I use the jog buttons on my mill to cut all the time... squaring up an edge and things like that.
[20:59:20] <BigJohnT> I use the feed override to get the cut speed (defaults to 40 IPM) and it only allows you to jog one axis at a time...
[20:59:40] <archivist> we have a toy cnc here where jog buttons is the only safe way (needs emc upgrade)
[21:05:33] <BigJohnT> you just have to convince the manager to let you do it!
[21:06:16] <archivist> I need to get the owner to let me be the owner
[21:06:50] <BigJohnT> that's even better :)
[21:06:54] <archivist> he says yes anyway, but I dont like messing with things I dont own
[21:07:11] <archivist> or dont get paid to do
[21:08:23] <archivist> I dont think an upgrade is much work on it at all as its just a crap controller to be replaced
[21:34:01] <tomp> i have a tiny screen on this eeepc. isnt virtual screen size handled by Xconfig? i cant find anything like it ( i used to use virtual screensizes back when)
[21:39:49] <alex_joni> good night all
[22:02:33] <dmess> hi all
[22:46:16] <tomp> changing to a virtual screen size wasnt very intuitive. the man xorg.conf would make you think it was adding "SubSection "Display" | Virtual blah blah | EndSubSection" but its that plus "Modes blah blah blah in the subsection plus setting gnome's Screen Resolution 'wizard' plus a hard reboot ( log out/in & ^altBKSP has no effect)
[22:48:12] <tomp> (hardy har har 8.04)
[22:59:37] <dmess> im stayin put with what i have working till i get another box..
