Back
[00:09:01] <MattyMatt> when they cancelled the local soap, they had trouble selling the sets (they built a real street) because of all the bodies buried under the patio
[00:11:37] <MattyMatt> the fact that all the houses were 3/4 scale, and had hastily bricked missing walls etc didn't help
[00:16:42] <DaViruz> kaylee frye <3
[00:41:18] <Jymmm> Um, she needs a boob job (or at least a push up) http://www.wallpaperbase.com/wallpapers/celebs/jewelstaite/jewel_staite_3.jpg
[00:42:09] <cradek> Jymmm: let's not get started on the things you need
[00:42:21] <cradek> (is she an emc user?)
[00:42:41] <frallzor> TiN coated tools, is that good for metals?
[00:42:52] <Jymmm> Yeah, she's fabricating bra inserts (I hope)
[00:42:57] <cradek> what metals?
[00:43:01] <frallzor> Alu
[00:44:55] <Jymmm> LOL, this is pretty good... http://www.collegehumor.com/video%3A1938053
[00:45:14] <KimK> cradek: I doubt that Jewel Staite is an EMC user, but I'm sure Kaylee Frye uses EMC47 to make replacement parts for the anti-gravity drive.
[00:46:39] <cradek> frallzor: I can't find a recommendation for TiN on Al in MH
[00:47:00] <frallzor> nm, the specs said Alu was fine it seems
[00:47:11] <frallzor> some data on feeds and speeds
[00:48:11] <frallzor> oh nm Ill just countersink some of the holes by hand and skip the ones not needed as it turned out
[00:48:16] <frallzor> cheaper =)
[00:54:58] <Valen> dont you be hating kayley
[01:03:37] <Valen> she be sexeh and if you don't like it she'll brain you with a wrench
[01:07:30] <Valen> </fanboy>
[01:10:08] <Valen> cocatoo is an exotic bird now?
[01:39:32] <Jymmm> Valen: In the US, yes. In AU, a pest as I understand it
[01:40:40] <L84Supper> that bird clearly qualifies to work for the DMV
[01:40:49] <L84Supper> as a manager
[01:40:51] <Jymmm> ?
[02:06:26] <alex_chally> gaaaah
[02:06:38] <alex_chally> * alex_chally spent all day in measurement hell
[02:08:42] <alex_chally> my screws need to be aligned within .002" over 16" horizontally and vertically
[02:10:53] <alex_chally> and I am boring the nut holder out to fit the ball nut, and setting up that square to it is proving slightly difficult
[02:11:22] <cradek> .002 over 16": don't breathe on it
[02:13:47] <alex_chally> cradek, yeah I figure no matter what I do I am going to have to shim it
[02:14:12] <alex_chally> as the nicest indicator I have is only graduated every .0005"
[02:14:31] <alex_chally> so reading between the lines, .00025 +- a bit
[02:18:00] <cradek> so aligned to what within .002? I don't see what you're doing
[02:19:06] <alex_chally> cradek, I believe aial missalignment
[02:19:09] <alex_chally> is the issue
[02:21:25] <alex_chally> hmm, that does not make a lot of sense though
[02:22:09] <alex_chally> the y axis is designed to float on one end, it seems it would droop more then that
[02:22:35] <cradek> (gently suggesting) maybe you are in measurement hell because you don't understand the problem well enough?
[02:23:26] <alex_chally> cradek, well I am in measurment hell because I want the alignment to be at the limits of my measuring equipment, which is well within the capabilities of the machine
[02:29:04] <alex_chally> cradek, well that and the horrifying thought that I might fuck it up. There are no replacement parts to be had and I don't feel like fixing anything
[02:32:10] <Valen> not quite a pest but fuckin noisy lol
[02:33:02] <Valen> why do the screws need to be aligned so precisley?
[02:43:42] <alex_chally> Valen, because that is what it says in the little one page info sheet that came with them :)
[02:43:58] <Valen> heh
[02:44:06] <alex_chally> i mean, that is .00125" per"
[02:44:13] <alex_chally> per 1"
[02:44:27] <alex_chally> which is not actually insane, just kinda difficult
[02:44:30] <alex_chally> er
[02:44:33] <alex_chally> i missed a 0
[02:44:35] <alex_chally> .000125
[02:45:06] <cradek> aligned to what is the question
[02:46:59] <alex_chally> oh, the ways
[02:47:03] <alex_chally> of the axis in question
[02:47:38] <cradek> well at least that's easy to measure then - you hook your indicator to the slidy bit
[02:47:53] <alex_chally> oh yes, it is easy to measure the screw
[02:47:58] <cradek> assuming it slides in a straight line of course
[02:48:20] <alex_chally> the problem is squaring the Y axis nut mount for the boring operation that I need t od o
[02:49:00] <cradek> can't you test that squareness with an indicator in the spindle?
[02:49:45] <alex_chally> cradek, yes, but there are multiple critical surfaces to possibly measure from and iwas getting discrepant measurements
[02:49:51] <alex_chally> http://www.flickr.com/photos/33383121@N04/4701046799/
[02:49:56] <alex_chally> that is the part that I am cutting
[02:50:16] <alex_chally> I mounted it to an angle plate, and indicated in the bore, but then when I tested against the angle plate I was not square any more
[02:51:48] <alex_chally> so then the question is was this an acceptable amount of missalignment from the factory for the acme threaded nut, or is it a factor that was accounted for in the hand scraping and fitting of that part to the saddle, or a warp in my angle plate (old as hell at a school, who knows who has dropped it)
[02:52:39] <cradek> ok I see what you're up against now :-)
[02:52:57] <alex_chally> if it is an acceptable amount of error for the ACME thread nut, then I should bore it square to the angle plate (and thus the mounting surface of the holder)
[02:53:13] <alex_chally> if it is something that was scraped in, I should bore square to the ohle
[02:53:14] <alex_chally> hole
[02:55:20] <alex_chally> i guess I could put my saddle and table back on the machine, put an indicator on the table and run it across the mounting point and check for relative squareness to the rest of the machine
[02:55:21] <cradek> too bad you can't line bore it somehow with it actually installed on the table
[02:55:46] <alex_chally> if the mount point is parallel to the table, then I should make my bore square to the angle plate
[02:56:01] <alex_chally> if it is not, I should align with the bore
[02:56:06] <cradek> yeah I think I agree
[02:56:14] <cradek> but don't trust any angle plate without checking it of course
[02:56:17] <alex_chally> fuck, that means putting the table back on
[02:56:24] <cradek> some are just for mounting stuff, not squareness
[02:56:37] <alex_chally> it is an adjustable plate, I had to square it
[02:56:44] <alex_chally> really nice one
[02:56:53] <alex_chally> old cast iron, hand scraped
[02:57:03] <alex_chally> made in detroit, could not see a mfgr
[02:57:32] <cradek> why do you have only one chance at this? you're not cutting that original piece are you?
[02:57:39] <alex_chally> I am
[02:57:41] <alex_chally> :D
[02:57:54] <alex_chally> and it is not a common mill
[02:58:06] <cradek> why not make the whole piece?
[02:58:15] <alex_chally> so if I fuck it up I have to ... do that
[03:01:18] <eric_unterhausen> I need to take a trip to HGR
[04:03:51] <elson> anybody still awake?
[04:47:46] <elmo40> alex_chally: where are you located? if you draw it up and send me a .dwg file, i could mill you one out of <insert material here>
[04:47:56] <elmo40> what ACME thread is it, 3/4" ?
[05:18:36] <foxtrot> foxtrot is now known as foxtroll
[05:18:44] <foxtroll> foxtroll is now known as foxtrot
[05:28:42] <elmo40> foxtrot: how are things?
[05:29:27] <foxtrot> elmo40, pretty good, I am trimming my Z axis wood to lower its weight
[05:29:37] <foxtrot> and I upped the current on my motor driver for Z
[05:29:48] <foxtrot> seems to have taken care of the torque issues
[05:30:02] <foxtrot> im still having a lot of trouble consistently milling where I want to
[05:30:23] <foxtrot> im like 33% that I actually hit the material with the dremel
[05:30:29] <foxtrot> the other 33% i miss it completely
[05:30:37] <foxtrot> the other 33% i go like an inch into it
[05:31:05] <foxtrot> im extending my rails and adjusting my gantry outwards another 6" or so
[05:31:13] <foxtrot> to get my workable area above the current 8.5"x3.5"
[05:31:44] <foxtrot> i think I can get to about 12"x10", its just going to be ugly with long rails sticking out the X and Y
[05:31:47] <elmo40> for the most part, weight (in the right areas...) equals rigidity. For the Z, though, it can cause missed steps.
[05:32:21] <foxtrot> i've got a big piece of MDF the entire length of my X axis, and 4 bearings on it, so i think its a little overkill
[05:32:37] <elmo40> no such thing as overkill ;)
[05:32:45] <foxtrot> hehe in machining thats definitely true :)
[05:32:58] <foxtrot> the more I mess with this machine though, the more I want to build a new, bigger, better one
[05:33:06] <foxtrot> fixed gantrys are a pain in the ass
[05:33:12] <foxtrot> I really want a moving gantry
[05:33:23] <foxtrot> with my stage/surface fixed
[05:33:35] <foxtrot> instead of the current way where I have X&Y plates moving all over the place
[05:34:03] <foxtrot> i wish I could find some simple plans for the mechanical aspect of something like that
[05:34:57] <elmo40> get larger motors before you extend things too far.
[05:36:37] <Jymmm> 440 v8 fuel injected
[05:36:43] <elmo40> does it make a nice circle? did you manage to tune the x and y axis properly?
[05:36:54] <elmo40> Jymmm: ahh, good times
[05:37:08] <elmo40> but i was thinking of a 427 3x2 barrel
[05:37:43] <elmo40> is it just me, or does the older Diamondville have Better specs the the more recent Pineview? http://ark.intel.com/Compare.aspx?ids=35641,43098,
[05:38:07] <Jymmm> http://media.photobucket.com/image/351%20blower/johngipson/superchargerpics002.jpg
[05:39:10] <foxtrot> elmo40, I made a circle but it looks a little off
[05:39:22] <elmo40> you need a super charger on a mustang... the only way to make it roll. :-P
[05:39:49] <foxtrot> Ive got relatively powerful motors, I was planning to build a bigger machine and use these same motors (nema17, 24v, 1.8deg, 2.5A) and just put old crappy salvaged printer motors on this machine
[05:39:57] <elmo40> foxtrot: could be many factors.
[05:40:08] <elmo40> nema17?
[05:40:11] <elmo40> powerful?
[05:40:23] <foxtrot> i dont know what powerful means in regard to that
[05:40:24] <alex_joni> elmo40: it's just you
[05:40:30] <foxtrot> nema17 is a mounting standard i think
[05:40:34] <elmo40> same sentence??
[05:40:41] <Jymmm> alex_joni: No
[05:40:47] <alex_joni> Jymmm: why?
[05:41:01] <Jymmm> alex_joni: Find NEMA17 with 230inoz or better
[05:41:15] <foxtrot> I just wish I could 100% master controlling location and workpiece distances in emc
[05:41:27] <foxtrot> everyones tried to help me but i just cant comprehend it properly
[05:41:27] <elmo40> foxtrot: my tiny nema23's are not enough power for my wee 9" x14" mill...
[05:41:47] <alex_joni> Jymmm: I was talking about Diamondville vs. Pineview
[05:41:53] <elmo40> foxtrot: if your Z is still acting up, it could be missing steps due to weight.
[05:42:03] <elmo40> alex_joni: just looks like it.
[05:42:06] <Jymmm> alex_joni: Sounds like minoe league baseball teams
[05:42:09] <Jymmm> monir
[05:42:11] <Jymmm> minor
[05:42:15] <alex_joni> Jymmm: it is :D
[05:42:22] <alex_joni> majour league is AMD
[05:42:24] <elmo40> less watts consume, almost half the transistors but practically the same 1.6GHz speed
[05:42:27] <Jymmm> alex_joni: *SMACK*
[05:42:49] <elmo40> what ma i missing?
[05:42:52] <Jymmm> alex_joni: Hey, a friend gave me a "portable computer"
[05:42:53] <elmo40> both 64-bit
[05:43:00] <foxtrot> elmo40, thats why i was going to trim the wood
[05:43:33] <alex_joni> "Additionally, TDPs are often specified for families of processors, with the low-end models usually using significantly less power than those at the high end of the family."
[05:43:35] <elmo40> foxtrot: do you have the link for your picture?
[05:43:57] <elmo40> alex_joni: true. but 1.6 vs 1.66 isnt much of a difference
[05:44:14] <alex_joni> elmo40: and integrated graphics for the Pineview
[05:44:15] <elmo40> but 13W compared to 8W is a lot!
[05:44:17] <Jymmm> alex_joni: (not this one - I wish) http://www.chassis-plans.com/rugged-portable-lunchbox-computer/mp3x17-3lcd-portable-computer.html
[05:44:41] <alex_joni> Jymmm: for some values of "portable"
[05:44:49] <elmo40> ya, u can carry it :P
[05:45:06] <Jymmm> That's still awesome =)
[05:45:10] <alex_joni> http://www.chassis-plans.com/rugged-portable-lunchbox-computer/images/mp3x17-soft-case-1280.jpg
[05:45:17] <Jymmm> But mine is only a single 15" LCD
[05:45:32] <Jymmm> alex_joni: Yeah, I have one of those too
[05:45:44] <elmo40> the power supply is AC :-P
[05:45:49] <Jymmm> but it's canvas
[05:45:49] <foxtrot> http://imagebin.ca/img/gq9tlr.jpg
[05:46:12] <foxtrot> worst. quality. picture. ever.
[05:46:19] <Jymmm> Come on, this IS awesome... http://www.chassis-plans.com/rugged-portable-lunchbox-computer/images/mp3x17-fnt-open-kbd-1280.jpg
[05:46:21] <elmo40> foxtrot: i thought only the plexi is moving.
[05:46:50] <elmo40> and you did have a better pic before...
[05:46:50] <alex_joni> Jymmm: I didn't say it isn't
[05:47:05] <fenn> lunchbox, where's the he-man and pink unicorns
[05:47:15] <Jymmm> alex_joni: liar, you just didn't SAY it - doen'st mean you didn't think it =)
[05:47:18] <foxtrot> that better picture was before i attached the dremel/electronics
[05:47:34] <foxtrot> elmo: the wood/plexi is moving
[05:48:19] <alex_joni> elmo40: also DMI vs. DSB http://en.wikipedia.org/wiki/Direct_Media_Interface
[05:48:28] <alex_joni> fenn: they're heading your way
[05:48:49] <fenn> better take more drugs
[05:49:39] <Jymmm> alex_joni: I'm planning on using it for cnc controller. Install maybe an atom board
[05:50:02] <Jymmm> alex_joni: I have a dual paraport pci card too
[06:07:58] <alex_chally> foxtrot, how goes it?
[06:24:34] <alex_joni> Jymmm: portable CNC controller?
[06:24:45] <alex_joni> now that's an idea for Aram K :P
[06:40:00] <Jymmm> alex_joni: aram what?
[07:41:59] <foxtrot> alex_chally, good man
[07:42:03] <foxtrot> sorry was at the grocery store
[07:42:28] <foxtrot> im still having trouble with getting my distances right
[07:42:44] <foxtrot> but i just think its my own stupidity
[07:42:48] <foxtrot> youve tried to explain it to me
[07:42:55] <foxtrot> im just not getting it
[07:43:00] <foxtrot> and still drilling into the board
[07:43:15] <foxtrot> emc keeps only letting me move like .1" total on my Z axis at times
[07:43:22] <foxtrot> im just confusing myself
[08:05:33] <alex_chally> http://www.r44sales.com/1992R22BetaforSaleSN2139.html
[08:05:34] <alex_chally> i want that
[08:06:19] <alex_chally> foxtrot, when you set the travel for you X axis, did you tell it that you wanted travel in the - direction not the + direction?
[08:07:05] <foxtrot> what do you mean
[08:07:21] <foxtrot> i was homeing it all the way to the left (-)
[08:07:29] <foxtrot> so i was setting travel to 0 to 8.5
[08:07:39] <alex_chally> foxtrot, in your ini file you specify the limits of your axis in both + and - direction
[08:07:48] <alex_chally> ah
[08:07:48] <alex_chally> see
[08:07:57] <alex_chally> travel is from -8.5 to 0
[08:08:01] <alex_chally> not 0 to 8.5
[08:10:17] <alex_chally> foxtrot, does that answer your question?
[08:10:51] <foxtrot> ohhh that must be whats wrong for my Z
[08:10:55] <foxtrot> what should i make the Z travel be
[08:11:09] <foxtrot> if I want its home to be at the top
[08:11:11] <foxtrot> and then it to come down
[08:11:26] <alex_chally> whatever the total travel of your Z axis is, but in the negative direction
[08:11:52] <alex_chally> i don't know if you do maths, but -|ztravel
[08:11:54] <alex_chally> |
[08:11:55] <alex_chally> damnit
[08:12:03] <alex_chally> -|ztravel|
[08:18:48] <Valen> questoion, tuing up our mill, I get it fairly close, then i use FF1 to zero out the position error when its running at one speed
[08:19:01] <Valen> thing is when i change the speed the error changes
[08:20:03] <foxtrot> so like
[08:20:15] <foxtrot> 0 to -6.5 if my Z travel is 6.5?
[08:20:23] <foxtrot> and then I move it all the way up and press home
[08:20:42] <Valen> you can put home anywhere in your travel btw
[08:20:48] <Valen> we have 0 at the bottom
[08:21:00] <Valen> but "home" at the top (if we used home switches)
[08:21:23] <foxtrot> well my problem now is getting it to actually make contact with the workpiece
[08:21:46] <foxtrot> its complicating things because im just using the premade examples
[08:22:07] <Valen> so whats the problem specifically?
[08:22:35] <foxtrot> umm
[08:22:37] <foxtrot> stupidity :)
[08:22:40] <foxtrot> user error :)
[08:23:02] <Valen> of course, but what paticular aspect ;-P
[08:23:45] <foxtrot> well i keep either milling into the air above my workpiece
[08:23:50] <foxtrot> or drilling through my table
[08:24:16] <Valen> have you touched off?
[08:24:23] <foxtrot> where should i touch off
[08:24:53] <Valen> your G code specifies heights in it
[08:25:04] <Valen> you need to tell EMC where the 0 in that gcode is
[08:31:52] <alex_chally> foxtrot, [01:20:17] <foxtrot> 0 to -6.5 if my Z travel is 6.5?
[08:31:53] <alex_chally> [01:20:25] <foxtrot> and then I move it all the way up and press home
[08:31:54] <alex_chally> this is correct
[08:31:58] <alex_chally> or, a correct way to do it
[08:32:02] <Valen> can you pastebin the code?
[08:32:11] <foxtrot> there is no code just yet
[08:32:18] <foxtrot> im trying to mill EMC2AXIS
[08:32:33] <alex_chally> foxtrot, you really should try to just do a square first
[08:32:37] <alex_chally> and a circle
[08:32:59] <alex_chally> a LOT more information can be figured about the machine (length reported vs length traveled among other things)
[08:33:08] <alex_chally> backlash can be calculated
[08:33:08] <Valen> eh its fun to press play and see things work though
[08:33:14] <alex_chally> and it will be a bit more predictable
[08:33:22] <Valen> can you pastebin the code?
[08:33:28] <Valen> I think its Z is at 0
[08:33:44] <Valen> or just the first bit of it at least
[08:34:15] <Valen> axis was the first thing we ran as well I think ;->
[08:34:51] <alex_chally> foxtrot, so with the change in the Z axis settings to a negative number, can you get all your axis properly homed?
[08:35:40] <Valen> all the mills I have seen have Z increasing as you go away from the table
[08:35:41] <foxtrot> yup
[08:36:02] <foxtrot> well I home it and then I press - to move closer to the table Valen
[08:36:14] <alex_chally> foxtrot, ok, so let me tell you a little story about a guy we like to call G54
[08:36:26] <Valen> what do the co-ordinates do
[08:37:39] <alex_chally> foxtrot, G54 is a command that sets what I will call a work co-ordinate system
[08:37:43] <djwez> hi guys! i have been trying to set up stepgen and ive been reprogramming all the files but now im getting an error when i lunch emc2.. it says parport.0.pin-24-out does not exist
[08:38:23] <alex_chally> foxtrot, a work co-ordinate system allows you to set a new 0 point anywhere you wish, after your machine is homed at it's limits
[08:39:34] <alex_chally> foxtrot, that would allow you to, for example, have multiple vices set up and to run the same job on each one, or quickly set your tool to run a couple inches above the part in the air so you can test the code for large errors
[08:40:03] <Valen> its also set at the start of most gcode files
[08:40:17] <Valen> as in setting which workspace your in
[08:40:36] <alex_chally> yes
[08:40:40] <Valen> I think its probably above his pay grade just at the moment
[08:41:04] <Valen> give the guy some success and lets get a pen drawing of axis on a bit of paper ;->
[08:41:18] <alex_chally> Valen, I was going to help him do a little program :)
[08:41:58] <alex_chally> and learning g54 makes life less frustrating
[08:42:48] <Valen> foxtrot needs to learn alot of Gcode before he can start using it,
[08:43:22] <alex_chally> Valen, also it will keep him from crashing in X and Y, as the axis software limits will work
[08:43:24] <foxtrot> i'd like to do a little program :)
[08:43:49] <Valen> G54 doesn't stop crashes
[08:44:09] <Valen> homing and limits are done in machine units, axis etc is in G54 by default
[08:44:20] <Valen> you need to take explicit action to get into machine units
[08:44:23] <alex_chally> oh?
[08:44:29] <alex_chally> huh, I was unaware of that
[08:44:37] <alex_chally> * alex_chally has not actually used EMC that much
[08:44:53] <Valen> everything is done in workplace cordinates
[08:44:57] <alex_chally> k
[08:45:32] <Valen> you need a Gsomething Xfoo Yfoo to tell it to go places in machine cords, its mainly used for stuff like tool changers etc aparently
[08:46:16] <Valen> to run the axis program he needs to touch off his Z at the right height, I'm just not sure what plane that is written for
[08:47:04] <alex_chally> Valen, interesting, all of the comercial controlers I have used make extensive use of having the machine co-ordinate system be seperate from the workplace co-ordinate system
[08:47:16] <Valen> it is seperate
[08:48:12] <Valen> but all G1's etc are done in workplace cords
[08:48:39] <Valen> you can set a workplace to have the same origion as the machine i believe
[08:51:37] <Valen> the emc2axis files initalisation line sets to G54 as i recall
[08:51:49] <Valen> i just don't know what height it does its "cuts" at
[08:56:41] <alex_chally> HMM
[08:57:03] <alex_chally> foxtrot, I am writing a quick program, what diameter is your cutter?
[08:58:46] <foxtrot> you mean my tooltip?
[08:58:58] <alex_chally> yes
[08:59:13] <Valen> if you can pastebin the first 4 lines i can get you running the axis program in a few minutes
[08:59:15] <Valen> tops
[08:59:46] <foxtrot> .101"
[09:02:05] <alex_chally> foxtrot, you should pastebin that code for valen
[09:02:11] <alex_chally> http://pastebin.com/
[09:02:16] <foxtrot> what code?
[09:02:20] <foxtrot> the EMC2AXIS?
[09:02:23] <Valen> yes
[09:02:58] <Valen> I just want to make sure of what height it wants to run at
[09:03:24] <Valen> also the first line is a good thing to explain all about workspaces and the like ;->
[09:03:55] <bricofoy> djwez, there is no pin 24 on a stadart //port, so there is a mistake in your HAL file
[09:04:09] <bricofoy> standart
[09:05:10] <bricofoy> djwez, max output pin is 17
[09:05:42] <djwez> ja so i found out. goign to have to make a new controler board
[09:06:15] <foxtrot_mill> Valen: the #1 #2 #3 #4 lines?
[09:06:27] <bricofoy> to be clearer, pins 1 2 3 4 5 6 7 8 9 14 16 and 17 are outputs, and 10 11 12 13 and 15 inputs
[09:06:28] <Valen> first 10 or 20 just to make sure
[09:07:47] <Valen> assuming you can copy and paste it
[09:08:13] <foxtrot_mill> i cant, that machine doesnt have net access
[09:08:18] <foxtrot_mill> so this might take a while
[09:08:23] <Valen> ok stop
[09:08:31] <Valen> it must be on the interweb somewhere
[09:08:47] <Valen> whats its name exactly?
[09:09:41] <foxtrot_mill> axis.ngc
[09:09:55] <foxtrot_mill> /usr/share/axis/images/axis.ngc
[09:10:50] <Valen> images
[09:10:56] <Valen> ok i didnt look there lol
[09:11:20] <Valen> why no net?
[09:11:54] <Valen> ok the cutting plane is at 0
[09:12:19] <Valen> so the easy way is to jog your machine down to where you want to start the start of the E
[09:13:05] <foxtrot_mill> its a desktop and i only have wireless
[09:13:24] <Valen> so put the tool on the point where you want the cut to start
[09:13:34] <Valen> then select X and press touch off
[09:13:40] <Valen> do the same for Y and Z
[09:14:06] <Valen> the cone should be at the same point in the view in axis then
[09:14:14] <Valen> jog up away from the part
[09:14:44] <Valen> set the feed override to like 5%
[09:14:47] <Valen> then run it
[09:14:59] <alex_chally> THAT FEEDOVERIDE STEP IS IMPORTANT
[09:15:06] <alex_chally> just sayin'
[09:15:07] <Valen> lol yeah
[09:15:15] <Valen> oh and put your hand over the estop button
[09:15:26] <alex_chally> and don't stick your dick in it
[09:15:41] <Valen> for the first try you might want to put the Z an inch above the table
[09:15:56] <Valen> gtg bbs
[09:16:02] <Valen> have fun
[09:20:41] <foxtrot_mill> ok im about to try
[09:25:28] <valen_mobile> did it work?
[09:27:42] <Fox_M|afk> Fox_M|afk is now known as Fox_Muldr
[09:29:39] <foxtrot_mill> im not sure yet
[09:29:45] <foxtrot_mill> hmm i set my Z home to -5.0
[09:30:04] <foxtrot_mill> and then i open emc and jog it to it sproper location (5 inches above table)
[09:30:18] <foxtrot_mill> and in the upper left corner it shows -4.7 for some reason
[09:30:59] <foxtrot_mill> and it shows the little white arrow thingas being *below* the EMC2AXIS logo
[09:31:34] <bricofoy> did youy touch off Z ?
[09:31:42] <bricofoy> you
[09:31:47] <foxtrot_mill> no
[09:31:51] <foxtrot_mill> not yet
[09:32:18] <bricofoy> so it's normal the EMC2AXIS preview is not zt the place you want
[09:33:00] <bricofoy> jog the Z axis to the place you want to mill the EMC2AXIS logo, then touch off Z
[09:33:13] <valen_mobile> you need. to touch off homing is not a requirement
[09:33:16] <bricofoy> and the preview will be ok with the real world :)
[09:34:28] <bricofoy> when you touch off, you say to EMC where the 0 of your work is, this as nothing to do with machine home position
[09:35:42] <bricofoy> setting the machine home is required for axes limits to work.
[09:36:18] <valen_mobile> limits are for pussies ;-)
[09:36:49] <bricofoy> so, basically, if you don't have home switches, first you jog to the _machine_ 0 (machin home) then home all your axes there
[09:37:09] <bricofoy> then jog to your work 0 and touch off
[09:37:12] <foxtrot_mill> it keeps adding .3
[09:37:24] <valen_mobile> its a g54 thing
[09:37:41] <foxtrot_mill> like i went into stepconf and changed my -5 to 0 to 5 to 0
[09:37:44] <valen_mobile> your homing still or are you zeroing
[09:38:35] <foxtrot_mill> im trying to home
[09:39:19] <valen_mobile> it will be off by your cordinate offset then
[09:39:24] <valen_mobile> so leave it
[09:39:47] <foxtrot_mill> well when i do that it says out of range
[09:39:51] <foxtrot_mill> because its 5.3
[09:43:50] <valen_mobile> set yiu limits large
[09:44:35] <valen_mobile> get it working then when yiu get what all the bbits do use them
[09:45:08] <foxtrot_mill> ok
[09:45:17] <foxtrot_mill> where are you ircing from? :)
[09:46:02] <valen_mobile> kfc
[10:05:42] <valen_mobile> running yet?
[10:06:12] <foxtrot> no I still cant get it to even run the program
[10:06:25] <foxtrot> i think im about to give up for the night, its 6AM and my brain is starting to hurt
[10:06:28] <foxtrot> thanks for all the help
[10:06:31] <foxtrot> im sorry I let you down :(
[10:07:50] <valen_mobile> lol
[10:08:02] <valen_mobile> turn the home and limits off
[10:08:14] <valen_mobile> like make the limits 10000000000

[11:58:02] <alex_joni> sdada
[11:58:24] <alex_joni> hrmm.. screen froze up
[12:09:29] <elmo40> very interesting. The Mazak I work on uses this 'card computer' setup: http://www.datasheetarchive.com/SCE8653711-datasheet.html
[12:09:42] <elmo40> only 133MHz ;)
[12:11:41] <elmo40> the newer machine, 2005, uses this: http://www.ibase-i.com.tw/ib300.htm
[12:11:47] <elmo40> 300MHz CPU.
[12:13:30] <elmo40> but the thing that i dont understand... i can shut down the computer and STILL run a program. I think the computer is only for the UI. Somewhere else, after you load the gcode into memory, is actually running the machine. I would like to know how they do that.
[12:30:04] <JT-Hardinge> it's magic
[12:41:18] <elmo40> cool link for the tinkering kind : http://www.packratworkshop.com/
[12:41:59] <foxtrot> hiya
[12:42:22] <elmo40> foxtrot: morning
[12:42:39] <foxtrot> * foxtrot wants to redesign his mill
[12:42:49] <foxtrot> * foxtrot also wants to fix his current one
[12:45:22] <bricofoy> foxtrot, wow, just a short sleep time :P
[12:46:11] <foxtrot> i havent been to bed
[12:46:35] <foxtrot> i think im just going to sleep tomorrow night
[12:46:52] <bricofoy> :P
[12:47:38] <bricofoy> I often do that when I repair car. far more efficient during the night, as noone comes to bother me
[12:48:43] <cpresser> finally, I finished the most important part in converting my mill to emc2: I added a sticker :D
[12:48:46] <cpresser> http://ca.rstenpresser.de/~cpresser/tmp/emc2.5pre_lenny/linux_cnc_sticker.jpg
[12:59:37] <JT-Hardinge> nice
[13:00:25] <elmo40> i need to pick up some of those linear bearing thingies...
[13:00:31] <elmo40> would make my machine run SO much better
[13:00:37] <elmo40> cpresser: love it :)
[13:15:26] <elmo40> http://www.openrp.com/
[14:11:00] <elmo40> anyone need to make a simple gear? http://woodgears.ca/gear_cutting/template.html
[14:11:47] <elmo40> can alter the angle to make a star ;)
[14:14:44] <i_tarzan> helical?
[15:38:00] <elmo40> http://zwibbler.com/
[15:44:47] <John_f_> cool have you used it yet?
[15:50:58] <elmo40> it feels like beta
[15:54:59] <pcw_home> Its cute but having to log in makes it obnoxious (at least to me)
[15:55:00] <pcw_home> that what I like about pastebin, simple file upload/download and no login needed
[15:58:57] <elmo40> login? for what?
[16:01:17] <DanielFalck> to save or share
[16:08:30] <tom3p> how about a cad to sketch converter? make it look like pencil work? http://infosthetics.com/archives/2010/06/bing_destination_map_automatic_napkin_sketching_of_maps.html
[16:27:37] <mikegg> pcw_home: www.bugmenot.com
[16:28:11] <mikegg> sometimes it works, sometimes not.
[16:35:42] <Jymmm> http://sfbay.craigslist.org/sby/tls/1821877118.html
[16:40:51] <Endeavour_> Endeavour_ is now known as EndeavourPM
[18:42:36] <Jymmm> * Jymmm drops a swarf... BAM!
[18:43:03] <ds2> Jymmm: are you machining sodium again? ;)
[18:43:41] <Jymmm> ds2: Just two days to go!!!
[18:43:49] <ds2> 2days til ?
[18:44:06] <Jymmm> ds2: Um, Independency Day
[18:44:23] <ds2> oh... that's boring here... no fireworks allowed
[18:44:47] <Jymmm> ds2: They are seling in Gilroy and Newark
[18:45:09] <ds2> Jymmm: real fireworks or the those miniwinejug thingies with the strings?
[18:45:24] <Jymmm> BUT... In Gilroy, you can only purchase packs, no individuals
[18:45:53] <Jymmm> ds2: I like safe and sane. I prefer lights over sound.
[18:46:11] <Jymmm> If I want sound, I'll pull out the glock.
[18:46:29] <ds2> =)
[18:46:59] <Jymmm> ds2: You're in S SJ, you should see them too
[18:47:31] <ds2> Jymmm: different expectations, I suppose.
[18:48:14] <Jymmm> Well, what do you expect since the city and many businesses no long have a fireworks show now.
[18:48:35] <Jymmm> Just the morters than ppl set off.
[18:48:41] <ds2> in other states, it gets more visual
[18:49:13] <Jymmm> Well, kick the dumbasses that have nfc and catch the neighborhoof on fire
[18:49:23] <Jymmm> then they'll allow fireworks again.
[19:43:49] <moop> So i've blown my driver circuits anyone have any suggestions?
[19:45:27] <moop> I think maybe uln2003 is no good for driving dc motors?
[19:46:18] <archivist> uln2003 is ok WITHIN its ratings :)
[19:46:43] <moop> I think maybe something strange happened?
[19:47:07] <ds2> how big of a DC motor are you using?
[19:47:23] <moop> I was under the impression that any number of darlingtons could be paralleled to give greater current?
[19:47:57] <archivist> only if you do some external power sharing
[19:48:09] <moop> I was running 7 in parallel which should have covered 3.5A??
[19:48:28] <ds2> don't you need a load balancing resistor?
[19:48:39] <archivist> 7 of them
[19:49:02] <moop> I dont know the motor ratings but looked like it was only drawing 1.1A?
[19:49:34] <archivist> did you have external resistors to power share
[19:49:35] <ds2> otherwise, you get stuff like thermal run away... one of them hogs current... so it gets hotter...which in turn causes it to hog more current...repeat til one pops, then the next one and then the next one....
[19:49:47] <moop> no external resistors
[19:50:07] <John_f_> doesn't matter if one transistor heats up is starts hogging current
[19:50:12] <moop> http://82.152.150.86/ppj/
[19:50:12] <archivist> you cannot parallel bipolars like you did
[19:50:43] <moop> should show a .jpg of my notes
[19:50:50] <archivist> or you can but the smoke gets out
[19:51:10] <moop> magic smoke escapes??
[19:52:26] <moop> I just spent 2 hours and a dollars worth of components, and now i feel like I have been cheated by ebay
[19:53:04] <moop> I have a search for power sharing resitors on google, thanks for advice
[19:53:31] <archivist> you also failed in your diagram, thats incorrect to reverse the motor current
[19:54:00] <moop> I always get diodes the wrong way round
[19:54:43] <archivist> its more basic than that, you need an H bridge
[19:56:02] <moop> H bridge are expensive, i wanted to use uln2003 as I had some in my junk box
[19:56:39] <moop> but i think an h bridge maybe the way to go
[19:57:06] <archivist> you need to source AND sink current
[19:58:07] <moop> the uln circuit did work for 5 minutes
[19:59:43] <moop> and its probably 20 times cheaper than an h bridge circuit
[20:00:31] <moop> but i guess my circuit idea has major faults or someone would have used it before
[20:13:54] <alex_joni> ss/away
[20:14:15] <Jymmm> alex_joni: SS/Minow
[20:18:18] <archivist> * archivist torpedoes Jymmm's SS/Minow
[21:20:36] <JT-Hardinge> I wondered what happened to the SS Minnow
[21:21:14] <alex_chally> JT-Hardinge, http://en.wikipedia.org/wiki/S._S._Minnow#S.S._Minnow_today
[21:22:09] <SWPadnos> The Professor made a nuclear reactor, which blew up, acting like a very effective giant flare, so they all got rescued. Except the boat, because it had been previously broken by some attempts to glue it back together.
[21:25:18] <JT-Hardinge> Skipper Shoes are getting harder and harder to find any more and use to be my favorite leisure shoe
[21:27:06] <alex_chally> JT-Hardinge, I am beginning to suspect you are a thousand years old
[21:27:07] <alex_chally> :-p
[21:28:37] <L84Supper> Dawn Wells or Tina Louise..... who would you rather be shipwrecked with? was the old question
[21:29:09] <JT-Hardinge> close to that I think
[21:29:11] <SWPadnos> Dawn Wells
[21:29:59] <SWPadnos> or Donna Douglas :)
[21:30:22] <L84Supper> the professor had built quite a few machines by the end of the series
[21:30:26] <SWPadnos> yeah
[21:31:08] <DanielFalck> with bamboo and that one transistor radio that they had
[21:31:38] <L84Supper> wow i just saw a recent pic of Donna Douglas..... getting my memory eraser out
[21:32:10] <SWPadnos> I think Bob Denver was in a movie where he played a bartender at some tropical bar, and at one point he said to a customer (while holding a couple of coconut-shell cups) "You know, I used to know a guy who could build a nuclear reactor out of a couple of these, but he couldn't fix a 3 foot hole in a boat"
[21:32:27] <L84Supper> heh I saw that film
[21:32:32] <SWPadnos> heh
[21:32:48] <alex_chally> anyone else here use Dropbox?
[21:33:33] <SWPadnos> the one on linuxcnc.org?
[21:33:57] <Jymmm> SWPadnos: I was going to ask you something, but I forgot. So, let me know when you remember, ok?
[21:34:03] <SWPadnos> will do
[21:34:13] <SWPadnos> I think it had to do with LED lighting or power supplies
[21:34:37] <Jymmm> SWPadnos: No, that was charger circuits. But this was somethign else.
[21:35:27] <SWPadnos> the packages all arrived
[21:35:37] <LawrenceG> cool... the SS minnow is about 5 minutes drive from here....
[21:35:44] <Jymmm> SWPadnos: Ah, very cool. I completely forgot about them.
[21:35:53] <SWPadnos> good for you :)
[21:35:53] <Jymmm> SWPadnos: Get your cords?
[21:36:05] <SWPadnos> yep. they're thick :)
[21:36:25] <Jymmm> SWPadnos: Yeah they are. Good stuff maynard!
[21:36:46] <SWPadnos> at least one of the lenses broke in shipment - oh well
[21:37:03] <SWPadnos> still a good deal
[21:37:25] <Jymmm> SWPadnos: Really? I even packed in newspaper and everything
[21:37:34] <Jymmm> so it wouldn't bounce around
[21:37:58] <Jymmm> I guess good for spare parts then
[21:38:31] <Jymmm> SWPadnos: He's still happy with them?
[21:38:44] <SWPadnos> I think maybe there was a piece of hardware under the lens in one package
[21:38:54] <SWPadnos> yep, happy they're with them
[21:39:02] <SWPadnos> huh, yoda speak
[21:39:08] <Jymmm> SWPadnos: Just the grill
[21:39:30] <Jymmm> SWPadnos: I taped newspaper to each of the lenses
[21:39:53] <Jymmm> SWPadnos: Musta been the Ooooops Gorillas - could get it replaced under the insurance
[21:40:11] <SWPadnos> oh yeah, they were insured, weren't they
[21:40:25] <Jymmm> SWPadnos: $100 per package iirc
[21:40:46] <SWPadnos> I got an invoice for $40 also - apparently the shipper number was missing on 4 of the packages, and they charge $10 to look it up (per package - jerks)
[21:42:34] <Jymmm> SWPadnos: BULLSHIT
[21:42:53] <Jymmm> SWPadnos: I have the copies right here, the acnt# is on every single one of them.
[21:43:05] <SWPadnos> can you mail those to me?
[21:43:48] <Jymmm> SWPadnos: As long as Oooooooooops ins't involved
[21:43:57] <SWPadnos> USPS, your favorite :)
[21:44:40] <Jymmm> Yeah, I can do that
[21:44:57] <SWPadnos> thanks
[21:45:19] <Jymmm> SWPadnos: Just email me the $0.86 =)
[21:45:32] <SWPadnos> I'll DCC it to you right now ;)
[21:45:46] <Jymmm> liar
[21:46:04] <SWPadnos> yep, that's me
[21:47:16] <SWPadnos> so there :P
[21:47:45] <Jymmm> SWPadnos: Fucker!
[21:47:59] <SWPadnos> maybe later, she's not even home yet
[21:48:05] <Jymmm> SWPadnos: It's in quotes. That's liek crossing your fingers when you say "I promise"
[21:48:27] <SWPadnos> oh, isn't that funny
[21:48:36] <Jymmm> =)
[21:48:51] <SWPadnos> I figured that I'd need the quotes since it's multiple words, but I guess that's not true with Take Command/32
[21:49:04] <Jymmm> Take what?
[21:49:34] <SWPadnos> the Win32 version of 4DOS
[21:49:38] <Jymmm> ah
[21:54:54] <Fox_Muldr> Fox_Muldr is now known as Fox_M|afk
[22:04:38] <alex_chally> so my enclosure came w/o a sub pannel
[22:04:49] <alex_chally> any problem with making one out of like 3/8" plywood or something
[22:05:55] <SWPadnos> usually you tap the sub-panel when you want to mount things on it - metal is definitely better
[22:06:01] <SWPadnos> it's also a nice ground plane
[22:07:34] <alex_chally> that is what I was thinking
[22:07:51] <alex_chally> hmm, I have some old 1/4" steel plate in my garage
[22:07:55] <alex_chally> but it is pretty warped up
[22:08:45] <alex_chally> maybe I should go purchase a proper bit of sheet
[22:09:45] <SWPadnos> probably
[22:56:13] <moop> has anyone ever tried orocos?
[22:57:33] <moop> would be interested if anyone has any comparisons between orocos and emc?
[23:05:42] <Jymmm> moop: orocos is a tookit, not a full blown application like EMC is
[23:08:40] <moop> i thought emc was a toolkit, programs like axis are the applications built on it?
[23:09:49] <alex_chally> w00t, new PSU works great
[23:09:58] <Jymmm> AXIS is just one of many UI's.
[23:10:10] <alex_chally> moop, my understanding is that EMC is a command line program and AXIS is a gui
[23:24:48] <andypugh> I think there is a bit more to it than that. I think there are features only available from code, not the command line, for example.
[23:25:15] <andypugh> Anyway, what I have been doing today...
