[00:32:11] <r00t-Shed> jdh, did you cut any knobs?
[00:32:45] <r00t-Shed> i think mine is going to be a little bit too big
[00:32:50] <r00t-Shed> http://i.imgur.com/jwtyz.png
[00:34:10] <djdelorie> is that millimeters, or inches?
[00:34:22] <r00t-Shed> inches but i accident mm in cad
[00:35:00] <Tom_L> JT-Shop what's the thread end diameter?
[00:35:35] <r00t-Shed> dj linuxcnc thinks its a 35inch knob
[00:35:57] <djdelorie> and that's too big? ;-)
[00:36:07] <r00t-Shed> easy to grab!
[00:36:44] <Tom_L> i'm not having much luck with this model. the lathe package is basically 2.5d
[00:36:59] <Tom_L> so i'm finding out

[01:33:49] <gmagno> erm... is there any home command in gcode? I mean, an instruction that would tell the parser that from that moment on it should consider that position as the zero reference (home)?
[01:36:13] <gmagno> scary silence here...
[01:36:17] <gmagno> :-|
[01:36:23] <djdelorie> SSHHHH!!!
[01:36:31] <gmagno> :-X
[01:37:22] <gmagno> djdelorie, you've been helping me a lot :) what can you tell me about this question?
[01:37:30] <djdelorie> it's self-referential?
[01:38:10] <djdelorie> there are eight words in it, and you forgot to capitalize the first one?
[01:38:46] <djdelorie> or did you mean the gcode question?
[01:38:47] <Tom_itx> JT-Shop you asleep?
[01:39:11] <gmagno> djdelorie, the gcode question, what else?
[01:39:29] <djdelorie> I was telling you about the question "what can you tell me about this question?"...
[01:39:48] <djdelorie> I don't know gcode itself that well, I know that "touching off" in linuxcnc sets the part-origin...
[01:39:51] <gmagno> bah... sometimes you complicate life
[01:39:54] <gmagno> :)
[01:41:24] <gmagno> I'm doing a gui for the grbl controller: http://postimage.org/image/z91ju28c5/ and I'm trying to implement a feature similar to the homing used by linuxcnc
[01:52:47] <Connor> okay, can someone point me into the right direction for setting up auto tool changer using the tool table etc ??

[01:55:57] <Connor> Yes? No? Maybe? Go Away? :)
[01:56:12] <jdh> but, the plugs/etc went out today.
[01:56:22] <Connor> Cool.
[01:56:36] <Connor> I need to find a source for cheap scrap alumn...
[01:57:20] <Connor> I need to start design a temp setup for the cylinder until I can get the belt driven spindle working.
[01:57:28] <r00t-Shed> nice
[01:57:33] <jdh> no junk yard there?
[01:57:43] -!- Guthur [Guthur!~user@] has joined #linuxcnc
[01:59:07] <Connor> I just need to find a machine shop or metal supplier who has shorts..
[01:59:35] <djdelorie> you can buy shorts online, but that kinda defeats the purpose...
[01:59:35] <Connor> I need some steel too.
[02:00:01] <Connor> Speedy Metals is nice.. but.. would rather have a local source.
[02:00:45] <jdh> shipping sucks for steel
[02:01:01] <Connor> jdh: My design for the draw bar is kinda cool..
[02:01:41] <Connor> Going take too plates and cut a circle in them (so they're each have half of it).
[02:02:10] <Connor> Those get sandwiched between two other plates with a little slack so they can slide back and force.
[02:02:28] <Connor> those plates will have a large hole large enough for the tophot of the draw bar to go through.
[02:02:44] <Tom_L> what tool plane does a lathe use?
[02:02:56] <jdh> xz
[02:03:45] <Tom_itx> G18
[02:03:51] <Connor> then going to have two bars with 45degree angles cut on them go through the top plate and will engage the plates that can move.. pushing them together.
[02:04:29] <jdh> I have briefly thought of power drawbars, but just can't picture it.
[02:04:46] <Tom_itx> feed tube
[02:05:16] <Tom_itx> oh he's working on spindle?
[02:05:37] <Tom_itx> my local guy has all the aluminum you could dream of

[02:06:56] <Connor> so first 3/4" stroke of the cylinder will cause the tophat to be captured and the last 1/4" will compress the belleville springs.
[02:06:56] <Connor> jdh once I figure it all out I'll have it done up in cad and will send it to you.

[02:08:38] <jdh> you could trade off stroke for pressure
[02:08:39] -!- cevad has quit [Ping timeout: 253 seconds]
[02:08:52] <Connor> how so ?
[02:10:01] <Connor> In the design I'm thinking of, I might even need the full 3/4" of stroke from the 1"
[02:10:07] <jdh> if you had a 2" stroke at half the required pressure, you could lever the cam to give half the stroke and twice the pressure
[02:10:26] <Connor> Oh. well.. Yea.
[02:10:54] <Connor> but, that would require even more complex mechanical design.
[02:11:05] <Connor> not as simple as a direct force pinch style.
[02:11:25] -!- r00t-Shed has quit [Ping timeout: 252 seconds]
[02:11:39] <jdh> so, your cylinder floats above the spindle when not in use?
[02:11:46] <Connor> yup.
[02:12:20] <jdh> I got another 'free' issue of Digital Machinist. It's almost interesting.
[02:12:29] <Connor> I even figured out a way to not have to use air to return it back. Just put a few PSI in the 1 return stage and cap it.
[02:12:35] -!- Tom_L has quit []
[02:12:55] <jdh> it won't hold
[02:13:03] <jdh> might for a while though. Put a spring on it?

[02:13:40] <Connor> Naahh.. I'll just re-pressurize it.. once in a a while.
[02:14:06] <Connor> Those things are pretty air tight...
[02:14:11] <jdh> need a check valve or something to pressurize it.

[02:14:58] <Jymmm> jdh: If I took a 10ft pipe filled it with water, would the bottom of the pipe be equiv pressure as being 10ft underwater?

[02:18:00] <Jymmm> Ok, I want to "test" something that say they are waterproof to 3m
[02:18:17] <Tom_itx> Jymmm you don't watch enough mythbusters
[02:18:17] <jdh> not water resistant?
[02:18:19] <Connor> wouldn't it matter on the size of the pipe ?
[02:18:30] <Tom_itx> remember that vertical tank they made?
[02:18:52] <Connor> which one? the one that busted? or the one out of the tubing ? :)
[02:18:58] <Jymmm> No, says waterproof to 3m for 20minutes
[02:19:08] <Tom_itx> the one they shot bulltet into
[02:19:09] <Jymmm> 30min
[02:19:12] <Tom_itx> bullets*
[02:19:19] <jdh> I wouldn't do it if you like whatever it is,.
[02:19:34] <r00t4rd3d> http://i.imgur.com/WQW6C.jpg
[02:19:37] <Jymmm> why?
[02:19:37] <r00t4rd3d> :D
[02:20:20] <jdh> I've had a lot of waterproof stuff that isn't. A lot of times, it says that the 3m is just static pressure. No splash, no abrupt pressure change
[02:21:15] <Jymmm> And that's what I want to test for =) 30day return policy FTW

[02:30:37] <Jymmm> Hello Dominos, do you deliver?
[02:30:38] <jdh> I can make calls maybe 10 miles out, if I hold the phone up fairly high
[02:31:56] <Jymmm> underwater?
[02:32:09] <jdh> no, on my boat, standing up.
[02:32:21] <Jymmm> awww, where's the fun in that?
[02:33:47] <Jymmm> I wonder if that dice omputer at 130ft voids your iphone warrnaty?
[02:34:35] <jdh> I actually have a $1900 dive computer, but don't tell my wife.
[02:35:48] <Jymmm> nor the cost of all those tanks in your garage =)
[02:36:18] <jdh> I've sold 6 or so fairly recently
[02:36:30] <Jymmm> 80lb?
[02:37:01] <jdh> they weighed a lot more than that
[02:37:08] <Jymmm> capacity
[02:37:23] <jdh> cubic feet
[02:37:27] <Jymmm> I have a 40lb N2 tank
[02:37:46] <jdh> two sets of double 130's, 1 set of 85's
[02:37:53] <Jymmm> ah
[02:38:02] <jdh> 40 lb?
[02:38:05] -!- ScribbleJ has quit [Ping timeout: 246 seconds]
[02:38:11] <jdh> or 40 cubic feet?
[02:38:48] <Jymmm> your right
[02:38:56] <Jymmm> cf
[02:39:16] <Jymmm> I'm confusing with propane tank 5gal / 20lbs
[02:39:25] <jdh> is it 5 gallons?
[02:39:38] <Jymmm> Well 19.x
[02:39:49] <r00t4rd3d> https://www.google.com/#hl=en&safe=off&output=search&sclient=psy-ab&q=john+hudson+diving&oq=john+hudson+diving&gs_l=hp.3...3356.14033.1.14632.,or.r_gc.r_pw.r_cp.r_qf.,cf.osb&fp=b8007472273293c9&biw=1600&bih=722
[02:39:57] <jdh> I got a non-empty one filled the other day, never coudl tell how much was in it. They put in like 3.4 gallons, but no idea how they knew it was full
[02:39:59] <Jymmm> since you can't fill a propane tank 100%
[02:40:00] <r00t4rd3d> is any of that you jdh?
[02:40:07] <jdh> dunno, it's one uglyass url
[02:40:20] <r00t4rd3d> google search
[02:40:31] <djdelorie> there's a plugin to unwrap the url for you...
[02:40:54] <Jymmm> jdh: When I get my 20lb tank refilled, it read 4.7 gallons on avg.
[02:41:05] <Jymmm> sometiems 4.5gallons
[02:41:10] <jdh> none of them looklike me.
[02:41:35] <Jymmm> jdh: I believe it's the back pressure that stops the filling.
[02:41:46] <Jymmm> auto shutoff
[02:41:51] <jdh> so, what does a normalish empty tank weigh
[02:42:13] <djdelorie> if a propane tank is "full" there's no room for vapor to form, so the tank just stops working
[02:42:17] <jdh> she filled it on a scale, but didn't set it.
[02:42:19] <Jymmm> 20lbs is the propane, net weight
[02:42:35] <djdelorie> my tank is 18 lbs empty, 38 lbs full
[02:42:43] <jdh> cool
[02:42:52] <djdelorie> it shoudl have a "tare" marked on the tank, that's the empty weight
[02:43:05] * Jymmm looks...
[02:43:14] <jdh> I have 3 tanks. I like to make sure the one I'm using on the smoker is full enough to last as long as needed.
[02:43:40] <Jymmm> TW 16.6 lbs
[02:43:51] <djdelorie> that would be it - Tare Weight
[02:44:00] <jdh> heh... guess I could have looked for that.
[02:44:29] <Jymmm> I didn't know, I only know about the certification date
[02:44:48] <jdh> cut3d did a nice job on that stl file for the clamp knob
[02:44:50] <Jymmm> top right of the collar, MM-YY
[02:45:06] <jdh> or it looks like it would if this demo version would save toolpaths
[02:45:31] <Jymmm> 10-12 == October 2012, bust be recert every 10 years
[02:45:54] <jdh> propane tanks get retested?
[02:46:00] <Jymmm> Yeah
[02:46:02] <jdh> surely not
[02:46:17] <Jymmm> well, they can hydro them
[02:47:05] <Jymmm> I buy used tanks off craigslist, if it's getting up there or has expired, I just exchange them at Lowes, then refill after that
[02:47:13] <jdh> when mine start looking bad, I take them to the exchange place
[02:47:24] <jdh> or if I need a full one and the cheap fill place is closed
[02:47:58] <jdh> last one I got a lowes/blue-rino felt half full. Didn't weigh it
[02:48:04] <Jymmm> I refill the 20# tanks for $16.34 out the door. that's with 4.6 gallons

[02:48:13] <Jymmm> they onyl fill them to 15lbs =)
[02:48:22] <Jymmm> says so on the label if you read it
[02:48:55] <jdh> $13.25 at the grill store, they have a sign saying they fill them unlike the trade in places.
[02:49:24] <Jymmm> $13 for exchange or refill?
[02:49:32] <jdh> fill
[02:49:42] <Jymmm> thats cheap
[02:49:47] <jdh> I think the exchange is like $28 here
[02:50:08] <jdh> they close at 5:30 during the week, 4:00 on saturdays
[02:50:10] <Jymmm> $22 out the door exchange at lowes

[03:44:10] <JessicaRN> hola folks. has anyone used pycam to generate gcode from stls?
[03:45:18] <Thetawaves> on occasion
[03:45:33] <JessicaRN> is it worth the dl?
[03:46:17] <Thetawaves> huh
[03:46:30] <Thetawaves> why don't you give it a try
[03:46:59] <JessicaRN> I'm hoping to create some stls from autodesk's online photo modeler app and then cut them on a fireball? (last statement: is it worth the time to download it?)
[03:47:14] <JessicaRN> what did you think of it?
[03:47:22] <JessicaRN> was it a decent app?
[03:48:03] <Thetawaves> i am a contributor/maintainer
[03:48:14] <Thetawaves> there is a lot of work being done on it right now
[03:48:15] <JessicaRN> of pycam?
[03:48:19] <JessicaRN> cool
[03:48:25] <Thetawaves> it has moved a long long way since the last stable release
[03:48:42] <JessicaRN> so, what are it's main weaknesses at the moment?
[03:49:00] <Thetawaves> nothing, it is godzilla.
[03:49:08] <JessicaRN> lol
[03:49:23] <JessicaRN> it can cut out my mom...
[03:49:25] <JessicaRN> cool
[03:49:46] <Thetawaves> there are other solutions
[03:49:58] <Thetawaves> but if you like to program, pycam is the easiest to get started on
[03:50:00] <JessicaRN> but seriously, when you compare it to bobcam or rhino, how does it stand up?
[03:50:08] <Thetawaves> lol what the fuck
[03:50:20] <Thetawaves> no where near
[03:50:48] <JessicaRN> please expand?
[03:50:49] <Thetawaves> we are open source CNC
[03:50:56] <JessicaRN> yeah, i know.
[03:51:07] <JessicaRN> thats why i ask about the limits of the app
[03:52:04] <JessicaRN> the long and short, will it take an stl file and make a mill toolpath in gcode?
[03:52:08] <Thetawaves> this would be OBVIOUS if you downloaded it and tried it out for your self.
[03:53:22] <JessicaRN> theta, you know, i get that. but there are like 7000 apps out there that all claim to be the best thing since sliced bread. I'm only in here asking questions so I can save a little time and limit my search. doesnt that sound reasonable?
[03:53:49] <uw> pycam is pretty good
[03:53:57] <uw> thats all i use to gen gcode
[03:54:18] <uw> however they dont damn respond to you on their irc chan, which is annoying
[03:54:35] <JessicaRN> you dont go out and drive every car ever manufactured before you decide to buy one. you read reviews and ask ppls opinions before you go shopping.
[03:54:50] <uw> well, thats kinda difffernt
[03:54:54] <uw> cause pycam is free
[03:55:07] <uw> if i could buy a car or get a free one, i wouldnt be really comparing options
[03:55:35] <JessicaRN> uw, if they are all as huffy as theta then I doubt the support is very helpful.
[03:55:58] <uw> oh on pycam? yea i dunno what hes mad at lol
[03:56:03] <Valen> if it took you 30 hours to learn to drive the free car only to find out it didn't do something you needed it would be kinda crappy
[03:56:29] <Valen> i think the general take away is most cam programs are kinda crappy
[03:56:29] <JessicaRN> uw, what do you think of it? what are the big limitations? what are the strengths?
[03:56:31] <uw> fortunately for me, personally, id still be happier with the free car.
[03:56:43] <JessicaRN> valen, thanks for that.
[03:56:55] <r00t4rd3d> pycam is slow to render stuff
[03:56:55] <uw> JessicaRN, well, its not always perfect. sometimes you have to fix what it generates manually
[03:57:10] <Valen> until you get to mastercam or something like that they all suck in their own special ways and they are all good at paticular things
[03:57:12] <Thetawaves> r00t4rd3d, tried it recently?
[03:57:19] <uw> it can be slow, on like 50k and up moves, ill admit
[03:57:20] <r00t4rd3d> i use it every day
[03:57:50] <JessicaRN> uw, poor optimization?
[03:57:58] <Thetawaves> r00t4rd3d, to be clear, you use the development version in the repository?
[03:58:08] <r00t4rd3d> no
[03:58:25] <Thetawaves> i made quite a few commits to speed it up a few months ago
[03:58:31] <uw> JessicaRN, Honestly, not really sure. Its really not bad though, I mean, i can deal with it
[03:58:32] <JessicaRN> valen, what is the current gold standard for cam apps?
[03:58:32] <Thetawaves> haven't made it into the standard version
[03:58:39] <r00t4rd3d> i mainly use it on windows
[03:58:42] <Valen> JessicaRN: probably mastercam
[03:58:44] <JessicaRN> uw, thx
[03:58:50] <Valen> i think its about $10-15k per seat
[03:59:04] <uw> yea see ^
[03:59:16] <Valen> we use rhinocam
[03:59:18] <Valen> v1
[03:59:20] <Thetawaves> r00t4rd3d, yeah, i made it so the toolpath can rotate/move in real time
[03:59:20] <JessicaRN> a flight to shenzen is cheaper... bet you can find it there for $35!
[03:59:29] <uw> ill take a car that is kinda slow with a seat that pinches the balls over some bullshit thats 10-15k
[03:59:38] <Valen> its got some shocking lack of optimisations
[03:59:40] <r00t4rd3d> cut2d is very nice but not free
[03:59:47] <Valen> but its easy to use
[04:00:00] <r00t4rd3d> cut2d is very easy too
[04:00:11] <JessicaRN> valen, have you used rhinos free offering? what are it's limitations?
[04:00:14] <Valen> I also use pcb2gcode
[04:00:22] <Valen> rhino has free stuff now?
[04:00:26] <JessicaRN> yeah
[04:00:34] <JessicaRN> called freemill
[04:00:36] <JessicaRN> i think
[04:01:00] <Valen> well blow me down
[04:01:06] <JessicaRN> is most of what you do cutting pcbs? do you do any complex 3d shapes?
[04:01:18] <Valen> mostly 3d
[04:01:33] <r00t4rd3d> http://i.imgur.com/WQW6C.jpg
[04:01:40] <JessicaRN> uw, luckily I don't have to worry 'bout pinched jiblets
[04:02:29] <JessicaRN> valen, i want to use this for art projects. lots of complex curves and such.
[04:02:57] <Valen> hows pycam at importing models these days?
[04:03:26] <JessicaRN> i'm going to try and start with stls generated by autodesks photo modeler and then modify and cut from those.
[04:03:26] <Thetawaves> it uses inkscape to do the translation
[04:03:30] <uw> haha fair enough!
[04:04:01] <uw> Valen, expect to edit them some...
[04:04:19] <Valen> thats what burnt me for it last time, i use rhino to model it
[04:04:43] <uw> i use autocad and yea, some mods are usually needed
[04:04:45] <Valen> if your doing 2d stuff then look at inkscapes gcode export plugins and such
[04:04:46] <uw> not much though
[04:05:37] <JessicaRN> i might do a pcb now and then, but mostly i'll be cutting sculptural pieces.
[04:05:56] <r00t4rd3d> my favorite programs are Microcarve, Cut2d and Sketchup with Phlatscript plugin.
[04:06:13] <Valen> if its all 2d/2.5d then you could even look at heightmap stuff
[04:06:46] <JessicaRN> funny thing? I own an old gerber prototyping machine. I'm planning on bumping the z axis from .5" to about 6"
[04:07:06] <JessicaRN> microcarve? What is that?
[04:07:19] <r00t4rd3d> image to gcode app
[04:07:33] <JessicaRN> is it 2.5d
[04:07:34] <JessicaRN> ?
[04:07:36] <uw> JessicaRN, whats the make and model on that machine?
[04:07:42] <uw> if you care to share
[04:07:49] <r00t4rd3d> http://microcarve.microcarve.biz/
[04:08:35] <r00t4rd3d> yeah 2.5d
[04:08:47] <r00t4rd3d> cut3d
[04:08:50] <JessicaRN> uw, dunno. I only had about 45 minutes to pick it up so i left a bunch of the guts. I only grabbed the x-y-z platform and the power supply
[04:08:53] -!- dhoovie [dhoovie!~noyeaaaaa@] has joined #linuxcnc
[04:09:01] <r00t4rd3d> is another app, I have it but havent tried it yet
[04:09:13] <JessicaRN> so the model number is no longer with the stuff.
[04:09:31] <uw> oh no! you left guts?
[04:09:39] <uw> guts are important
[04:09:48] <JessicaRN> sadly, i did not get the drivers. I'll need to make my own. the steppers are funky
[04:10:06] <uw> bipolar type?
[04:10:18] <uw> its all good they work just fine
[04:10:24] <JessicaRN> yeah, guts are important, but it was a last minute salvage operation and time was limited
[04:10:26] <uw> my mill is keepin it real with bipolars
[04:10:49] <uw> oh so it was free?
[04:10:51] <uw> nicee
[04:11:29] <JessicaRN> well, kinda. i bought a whole house full of misc crap from the estate of a mad scientist.

[04:12:02] <uw> nice
[04:12:24] <uw> you have already peaked my interested at "mad scientist estate sale"
[04:12:26] <JessicaRN> so, do you have an original gerber as well?
[04:12:40] <uw> no but i am looking for one
[04:12:47] <uw> very much so
[04:12:47] <JessicaRN> ahhh...
[04:12:51] <uw> as well as a pick and place
[04:13:00] <JessicaRN> a pnp would be nice
[04:13:11] -!- FinboySlick has quit [Quit: Leaving.]
[04:13:46] <uw> sho would
[04:13:47] <JessicaRN> i used to have a mitsubishi movemaster arm that was designed for pnp. bought it salvage for $200 and sold it for $2500
[04:14:02] <L84Supper> you never hear stories about slightly irked or mildly neurotic scientists, just mad ones
[04:14:11] <JessicaRN> lol
[04:14:25] <uw> haha yea those movemasters
[04:14:41] <uw> wow 2500 is pretty good
[04:15:09] <uw> i would want the arm, but for that profit margin id probably sell it too
[04:15:43] <JessicaRN> this guy was a biology phd who framed houses for a living. his whole home was converted into a lab and tinkerer's workshop. his family had no idea what to do with all the stuff and i was there at the right time. i made an offer for the whole lot.
[04:16:19] <uw> awesome, any pics?
[04:16:37] <uw> i recently did a simlar thing to a guy who used to work at westinghouse
[04:16:56] <JessicaRN> i have about 4 centerfuges, a few spectrometers, etching tanks, the gerber, the SEM, a sputter coater, and a ton more

[04:17:34] <L84Supper> have you tried the SEM yet?
[04:17:41] <JessicaRN> i have a nice chemistry fume hood I'm selling soon
[04:17:48] <uw> mozmck, where are you located just curious?
[04:17:55] <mozmck> north texas
[04:18:01] <JessicaRN> sold the SEM first off. it paid for everything else
[04:18:06] <L84Supper> JessicaRN, where are they located? (the hoods)
[04:18:11] <JessicaRN> Indiana
[04:18:15] <JessicaRN> I have just one
[04:18:19] <L84Supper> oh really
[04:18:24] <JessicaRN> yeah
[04:18:32] <L84Supper> <--- Chicago
[04:18:40] <L84Supper> what size hood?
[04:18:43] <uw> mozmck, rats, a little far for me (nyc area) do you know the make/model?
[04:18:51] <JessicaRN> sec, i'll get the specs
[04:19:51] <JessicaRN> L84Supper: it looks like this one: http://www.ebay.com/itm/Kewaunee-Scientific-Air-Flow-Fume-Hood-38-KSE-k-s-e-lAB-/190532376221

[04:27:08] <L84Supper> JessicaRN, high shear mixers, viscometers, stainless tanks
[04:27:15] <JessicaRN> yeah, a bunch of etchant stuff
[04:28:15] <L84Supper> ferric chloride?
[04:28:33] <uw> nitric acid?
[04:28:42] <JessicaRN> L84Supper: yeah, like a 5 gal jug of powder.
[04:29:08] <JessicaRN> L84Supper: I have a few large dewars. could you use those?
[04:29:12] -!- vladimirek [vladimirek!~vladimire@] has joined #linuxcnc
[04:29:37] <JessicaRN> uw, no nitric
[04:30:02] <uw> ok
[04:30:15] <JessicaRN> i do a lot of my own etching w/ muratic acid
[04:30:40] <djdelorie> mmm... chemicals...
[04:30:51] <JessicaRN> L84Supper: the dewars are stainless
[04:30:53] <L84Supper> also might need some Polymerization Reactors
[04:31:16] <JessicaRN> no idea what those are so i doubt i have them!
[04:34:28] <L84Supper> stainless tanks with lids that are plumed for gases and fluid exchange
[04:34:50] <L84Supper> http://www.godrejped.com/godrej/processEquipment/ProductImages/Polymer-Reactor.jpg
[04:34:55] <JessicaRN> nope. only have the dewars
[04:35:18] <JessicaRN> whatcha makin?
[04:35:26] <L84Supper> polymers
[04:35:37] <JessicaRN> heh
[04:35:43] <JessicaRN> yeah... for what
[04:36:25] <L84Supper> http://www.shcm.es/ing/imagenes_grandes/BAYER%202000.jpg this looks like a fuel tank from a Saturn V
[04:36:53] <L84Supper> JessicaRN, we make photopolymers for 3D printers and also for inks, coatings etc
[04:37:03] <JessicaRN> if you are into that, do you know anything about synthisizing uv curable resins for rp applications? that stuff is SOOO expensive. it would be nice to make it myself
[04:37:20] <L84Supper> heh, how about $40/L?
[04:37:28] <JessicaRN> ahhh... so yes, you do know about that stuff!
[04:37:43] <L84Supper> http://bucktownpolymers.com/polymers.html
[04:37:52] <JessicaRN> $40/L is a pretty good price compared to some I've seen
[04:38:30] <L84Supper> I have hundreds of formulas
[04:39:15] <JessicaRN> can the inexperienced home chemist tackle any of them?
[04:40:20] <L84Supper> DIY heh, sorry no
[04:40:34] <JessicaRN> sux 2 b me
[04:40:48] <L84Supper> safety and also have to buy in large volumes
[04:40:54] <JessicaRN> yeah
[04:41:06] <toner> oooh
[04:41:12] <JessicaRN> so, what part of chi you in? is bucktown your company?
[04:41:13] <toner> polymer manufacture?
[04:41:14] <L84Supper> they don't like to sell chemicals in small containers unless they are $5000/L then it;s ok
[04:43:12] <L84Supper> http://code.google.com/p/lemoncurry/wiki/main
[04:44:16] <JessicaRN> yeah, i've seen that. sexy
[04:44:42] <JessicaRN> makes cnc milling look like stone tools and sticks
[04:44:55] <JessicaRN> so, what part of chi you in? is bucktown your company?
[04:44:57] <L84Supper> will be printing printed circuit boards from fluids later this year
[04:45:21] <L84Supper> no plating, etching, laminating or drilling
[04:45:31] <JessicaRN> tres cool
[04:45:54] <djdelorie> with through-vias?
[04:46:25] <L84Supper> multilayer with through, blind and buried vias
[04:46:37] <djdelorie> sweet
[04:46:51] <djdelorie> resolution?
[04:47:15] <L84Supper> 1/10 UL
[04:47:29] <djdelorie> ultraliters?
[04:47:36] <L84Supper> heh
[04:47:49] <djdelorie> what's that in trace/space rules?
[04:47:50] <L84Supper> UL is 3 mil trace /space
[04:48:02] <L84Supper> 75um for the metric folks
[04:48:15] <djdelorie> so 0.3mil features. Cool. When will it be ready for other DIY'ers?
[04:48:32] <L84Supper> 5um trace space should be pretty common soon
[04:49:00] <JessicaRN> L84Supper: will you be offering the fab services or just the chemicals?
[04:49:17] <L84Supper> printers and fluids
[04:49:43] <L84Supper> there should be some DIY wikis by the end of the year
[04:50:06] <L84Supper> the main problem with DIY are the chemicals
[04:50:19] <JessicaRN> yeah
[04:50:23] <djdelorie> worse than the usual pcb chemicals?
[04:50:49] <L84Supper> I was a bit surprised by the lack of machine building/design skills
[04:51:01] <L84Supper> actually much safer
[04:51:34] <L84Supper> if you've sen the reprap variations you know what i mean
[04:51:53] <JessicaRN> so, what are your printers gonna run?
[04:51:56] <djdelorie> my lab already includes hcl, cucl, sodium carbonate, sodium hydroxide, stannous boroflourate, and probably a few other things...
[04:52:23] <JessicaRN> djdelorie: you need to buy my fume hood...
[04:52:25] <JessicaRN> ;)
[04:52:30] <L84Supper> so I'm not sure how realistic <5mil trace and space DIY might be, some here should be able to do it, others .... not so much
[04:52:35] <djdelorie> I need to buy ANOTHER fume hood at least
[04:52:42] <djdelorie> the first one didn't survive the acids
[04:52:46] <JessicaRN> lol

[04:53:16] <JessicaRN> that is not my listing

[04:55:01] <djdelorie> who, me?
[04:55:10] <JessicaRN> yep!
[04:55:56] <JessicaRN> so will i, prolly.
[04:56:07] <JessicaRN> you live, you die... repeat
[04:56:16] <djdelorie> I don't use that stuff that often. And family medical history disagrees too ;-)
[04:57:09] <JessicaRN> good for you.
[04:57:21] <djdelorie> more likely to die of something else, that's all :-P

[05:43:24] <Loetmichel> ... to qoute Roger murtaugh : " damn, i am to old for this shit!"
[05:43:43] <Loetmichel> in germany
[05:44:44] <JessicaRN> thats a big place. what part? (unlike most americans I know a little about the rest of the world!) ;)
[05:44:58] <Loetmichel> wuppertal
[05:45:30] <JessicaRN> cool. i've been to hamburg, frankfurt, and munich
[05:45:42] <Loetmichel> but as the company was stage rental we had jobs all over germany, even as ar as maroc
[05:45:59] <Loetmichel> far
[05:46:02] <JessicaRN> *nods*
[05:46:29] <JessicaRN> I want to move back to Europe. I think I'll try Italy next.
[05:47:21] <Loetmichel> (that was a nice job, to nuild a stage with laser show and water show in the desert
[05:47:28] <Loetmichel> (west sahara) ;-)
[05:47:32] <Loetmichel> build
[05:47:48] <Loetmichel> in the middle of nowhere ;-)
[05:48:24] <JessicaRN> I saw a great light/water show at planten un blomen hamburg

[05:51:09] <JessicaRN> have fun
[05:51:17] <Loetmichel> .. still sipping on my triple espresso... ;-)
[06:07:00] <JessicaRN> Loetmichel: do you know pycam?
[06:11:05] <Connor> I like CamBam.
[06:11:19] <JessicaRN> free?
[06:11:42] <Connor> No. But really not that bad $$$ wise.. You can use it free for like 40 or so times.
[06:11:57] <Connor> I had a machine that I ran it on for months.. Just left it up all the time.
[06:12:38] <Connor> Very Easy to use.
[06:12:48] <Connor> much easier than most cam's I've tried.
[06:13:10] <JessicaRN> i'm looking to create stls with autodesk 123d catch and the mill them. you think it can do this?

[06:15:30] <JessicaRN> the pycam importer has choked on every stl i've tried to open
[06:15:55] <Connor> You using it for CNCing or 3D printing ?
[06:16:02] <JessicaRN> cnc
[06:16:25] <JessicaRN> i wish i had a 3d printer
[06:17:18] <Connor> They're fun.. But a pain to get your settings correct.

[06:24:05] <dhoovie> cambam is great. for 2.5d things
[06:24:21] <dhoovie> never used it for anything else though
[06:25:31] <JessicaRN> only 2.5d?
[06:25:35] <JessicaRN> sucky
[06:25:54] <toastyde1th> most cheap cam packages are shit at everything that isn't 2.5d
[06:26:11] <JessicaRN> anyone used bobcam?
[06:26:22] <dhoovie> yup, tbh never used it for 3d. may work. may....
[06:26:39] <JessicaRN> you likey?

[06:28:18] <toastyde1th> also we might have different definitions of 2.5d
[06:28:32] <JessicaRN> i want to use this mill for sculptural pieces.
[06:28:57] <L84Supper> whats the current price of mastercam?
[06:29:10] <JessicaRN> i'm going to scan found objects using 123d catch and then blend/merge them into art pieces.
[06:29:10] <mrsun> your soul and left foot ?
[06:29:11] <L84Supper> $10K +
[06:29:32] <toastyde1th> JessicaRN, do you have a specific toolpath that you are a looking for?
[06:29:48] <toastyde1th> because on a 3 axis mill, almost every single cam package is going to use a 2.5d toolpath to do contouring
[06:30:10] <JessicaRN> so, just no undercuts?
[06:30:38] <JessicaRN> I'd like to be able to rotate my pieces to get a full 3d cut.
[06:30:58] <toastyde1th> full rotation/undercutting needs a 5+ axis machine, which is why i was curious
[06:31:07] <L84Supper> dhoovie, expensive? the photopolymers are the same price as PLA and dropping
[06:31:31] <JessicaRN> or it needs a 3d machine and someone to manually rotate the piece!
[06:31:41] <toastyde1th> once you have 4 or more axes, then you have a little bit of choice over what kind of toolpath you use
[06:33:03] <JessicaRN> i was under the impression that some of the better apps would allow you to manually rotate your piece and then continue cutting using the same model. am i wrong about this?
[06:33:19] <toastyde1th> no no, you're correct - that's a very standard operation
[06:33:38] <toastyde1th> what I'm referring to is how the machine actually goes about cutting the 3d feature
[06:34:11] <JessicaRN> so, toastyde1th would that be a 2.5 or a full 3d cut?
[06:34:21] <toastyde1th> you can contour with a 2.5d cut
[06:34:41] <toastyde1th> the 2.5d just means the machine goes in a staight line, like X, and moves Z up and down to make the profile
[06:34:42] <JessicaRN> and then rotate and contour another face?
[06:34:46] <toastyde1th> then bumps y up
[06:34:52] <toastyde1th> and makes another pass in X and Z
[06:34:55] <JessicaRN> ahhh
[06:34:56] <JessicaRN> ok
[06:34:59] <toastyde1th> and just keeps doing this until your part is cut
[06:35:19] <JessicaRN> still do complex curves in all three axis?
[06:35:26] <toastyde1th> yes, up to a point
[06:35:42] <JessicaRN> ok, so, just basically no undercutting?
[06:35:50] <toastyde1th> you can undercut with a spherical endmill
[06:35:53] <dhoovie> L84Supper: yeah :D and i love the fact its dropping. hmmm..... moar quality
[06:36:11] <toastyde1th> but you'd have to look at your specific cam package to see if it supports that kind of thing
[06:36:16] <JessicaRN> ok. yeah, i see that
[06:36:36] <JessicaRN> sheesh. i wish i could apprentice with someone
[06:36:36] <toastyde1th> some cam packages handle special endmill shapes, others don't
[06:36:47] <JessicaRN> what do you use?
[06:36:55] <toastyde1th> and i don't have enough exp with cam packages to help, all my exp is with hand-coding in a production environment
[06:36:59] <L84Supper> dhoovie, the old patent holders did nothing for over 20 years, now it's time for a change
[06:37:25] <JessicaRN> you write gcode from scratch toastyde1th ?
[06:37:33] <dhoovie> i like change. change is good. especially when it benefits everyone.
[06:37:41] <toastyde1th> JessicaRN, yes, but it's for parts, not for sculpture/etc
[06:37:58] <toastyde1th> so there's no complex surfaces or contours, it's all straight lines, angles, and circles
[06:38:11] <JessicaRN> how does one code for a curve in 3 axis? like a screw helix?
[06:38:18] <toastyde1th> g2/g3
[06:38:50] <toastyde1th> you tell the machine the two axes that will be the circular motion, and which will be linear
[06:38:52] <JessicaRN> sheesh. i doubt my geometry is that good!
[06:38:53] <dhoovie> also, PLA is sometimes a pain in the butt. and extruders are fussy sometimes. and i hate stringing! but I doubt i will get cheap UV cure resin in this part of the world
[06:38:55] <dhoovie> which sucks
[06:38:58] <toastyde1th> JessicaRN, it's not geometry
[06:39:14] <toastyde1th> gcode is pretty well designed for circular/helical moves
[06:39:14] <JessicaRN> what is it then?
[06:39:27] <L84Supper> dhoovie, what part of the world is that?
[06:39:36] <dhoovie> india :D
[06:39:45] <L84Supper> no problem
[06:39:46] <toastyde1th> it's just putting the machine into the right modes, moving it to the start of the cut, then telling it what kind of cut you're making
[06:39:53] <dhoovie> you'll get resin for sure. but they are going to charge for it
[06:39:59] <JessicaRN> well, so far the only gcode i have written is the really basic g0 stuff
[06:40:11] <L84Supper> dhoovie, give it 6 months
[06:40:18] <toastyde1th> g2/g3 tell the machine to move in an arc
[06:40:23] <toastyde1th> so that you can cut a circle
[06:40:29] <JessicaRN> i guess i need a good gcode tutorial
[06:40:39] <toastyde1th> if you are cutting a circle in X/Y, but tell it to move in Z at the same time
[06:40:46] <JessicaRN> can you suggest a good reference?
[06:40:47] <toastyde1th> it will move in a line in Z, not circular
[06:40:52] <toastyde1th> I learned it the hard way =(
[06:40:56] <dhoovie> well, i still don't have a decent source for abs. unless i import. or I havn't found one. Sooooo.... I don't think I'll be holding my breath
[06:40:59] <L84Supper> dhoovie, whats the import tax from China?
[06:41:05] <toastyde1th> co-worker taught me the basics, then i read the Fanuc manual
[06:41:16] <toastyde1th> i also went to a votech program
[06:41:30] <dhoovie> I really havn't checked to be honest. But it's usually about 20-25%
[06:41:34] <dhoovie> for most things
[06:41:35] <JessicaRN> fanuc?
[06:41:38] <toastyde1th> i am sure there are some good gcode references in the emc wiki
[06:41:46] <toastyde1th> Fanuc is the de facto standard machine control
[06:41:51] <JessicaRN> sounds like an Italian swear word
[06:41:55] <L84Supper> dhoovie, if we find the right partner there we can make it in India
[06:42:20] <JessicaRN> "fanuc you, buddy!"
[06:42:22] <L84Supper> dhoovie, $40 + 25% = $50
[06:42:24] <toastyde1th> haha
[06:42:27] <L84Supper> so not too bad
[06:42:42] <toastyde1th> the one bad thing about knowing fanuc gcode is that emc gcode is fairly different
[06:42:47] <dhoovie> plus shipping? it doesnt turn out cheap in the end. but yeah i guess it's not too bad
[06:42:50] <toastyde1th> it's actually different from most manufactuer controls
[06:43:40] <JessicaRN> Shhh... don't tell anyone, but I'm also using another tool besides EMC
[06:43:46] <JessicaRN> *grins*
[06:43:47] <L84Supper> dhoovie, several components we use for resin is actually made in India, we just need a small factory
[06:43:50] <toastyde1th> lol
[06:44:19] <dhoovie> really? well I hope it happens.
[06:44:40] <dhoovie> and I hope they sell it cheap to the smaller guys :D who only want maybe 10 litres :D
[06:45:08] <L84Supper> dhoovie, most offers from India so far have been a bit sad, but we have been focusing on China, India is next

[06:47:31] <dhoovie> tbh, if you can find the right person to work with it's fairly easy in india

[06:48:06] <L84Supper> but corruption got in the way, we just need the right connections and partners
[06:48:30] <dhoovie> L84Supper: haha yeah you need to know how to 'play' the system.
[06:48:56] <L84Supper> it generally involves some 20%+ non income generating "partner" to move ahead
[06:48:58] <dhoovie> and by that i don't mean just giving in to corruption. but generally being able to deal with people here

[06:53:00] <Connor> After you define the machine operation.. You go in to the options of operation and set the type of tool..
[06:53:32] <Connor> what type of endmill you using ?
[06:53:51] <JessicaRN> lol @ L84Supper
[06:54:07] <JessicaRN> Connor: dunno yet. I have a lot of choices
[06:54:18] <JessicaRN> probably a small ball mill
[06:54:29] <Connor> I think Bull nose or ball is in it..
[06:55:16] <Connor> All kinds of Tutorials online and a forum.. I mostly use it for 2.5d stuff..
[06:55:40] <JessicaRN> conner, i just imported a part i d/led from 123d catch, but its orientation is screwy. how can i reorient the part?
[06:56:09] <L84Supper> JessicaRN, China is a bit like Soylent Green with some humanity, they are the true capitalists
[06:56:14] <Connor> Orientation screw in what way? Rotated wrong?
[06:56:31] <JessicaRN> IT'S PEOPLE!!!
[06:56:40] <Connor> I think you can select the whole part using the shift button and highlight..
[06:57:25] <JessicaRN> Connor: the part I d/led is a wall hanging. its default orientation is vertical but for milling I want it to be hort.
[06:57:57] <Connor> highlight the whole part.
[06:58:12] <Connor> edit transform.
[06:58:24] <L84Supper> hmm so lets see, communists that are actually capitalists, and we have a supposed democratic republic turned fascist.... but don't tell anybody
[06:58:25] <Connor> and you should be able to rotate it
[06:58:44] <JessicaRN> hmmm. i cant see to select it
[06:59:11] <Connor> hold down alt key and use the mouse to rotate the axis
[06:59:15] <JessicaRN> it does -act- like i'm selecting it.
[06:59:24] <Connor> it should turn red.
[06:59:44] <JessicaRN> that just rotates the viewing axis
[07:00:23] <L84Supper> anyone try the comedi + EMC stuff?
[07:00:27] <JessicaRN> even "select all" doesnt turn it red
[07:01:23] <Connor> I'm not sure how to rotate it like that...
[07:01:39] <Connor> might be easier to do it in the CAD package and save it back out.
[07:01:41] <JessicaRN> foo
[07:01:52] <JessicaRN> ok
[07:04:41] <Connor> rotate will do it I think..you may have to use the X y or Z buttons on keyboard to select the correct axis to rotate around...
[07:05:39] <JessicaRN> Connor: Here is the part I'm playing with: http://www.123dapp.com/obj-Catch/Sun-Face/725400
[07:05:59] <JessicaRN> I'm trying to get it to lay flat on the xy
[07:06:25] <Connor> I don't have account to download it with.
[07:06:40] <JessicaRN> ok
[07:07:36] <Connor> But, I see what your saying. They have it hanging on the wall.. and you need laying flat on the "table" :)
[07:07:57] <Connor> Would be trivial in Inventor to rotate it.
[07:08:18] <JessicaRN> dont have inventor

[09:33:44] <anonimas1> tho i spent like 2 weeks getting my post to a decent stage where i dont have to worry about it
[09:34:08] <Tom_itx> if i saw a lathe file for linuxcnc i could fix one pretty easy
[09:34:38] <Tom_itx> does yours use G96?
[09:34:48] <Tom_itx> constant surface speed...
[09:35:06] <anonimas1> yes
[09:35:24] <Tom_itx> i think most lathes do
[09:35:35] <anonimas1> only thing not working is the drill cycle so i post that as separate moves
[09:35:54] <anonimas1> the fanuc manuals are abysmal.
[09:36:15] <Tom_itx> heh
[09:36:41] <Tom_itx> i found my old okuma lathe pocket reference the other day
[09:36:44] <anonimas1> as i didnt have a drill chuck when i were working on the post it werent a big deal
[09:37:05] <anonimas1> but all other canned cycles works as expected
[09:37:18] <Tom_itx> have you tried rigid tapping with it?
[09:37:35] <anonimas1> too old control im planning on making a floating chuck for that
[09:38:00] <Tom_itx> get a reversing head for it
[09:38:07] <anonimas1> i have one :)
[09:38:24] <anonimas1> but it's too big to fit the lathe
[09:38:29] <anonimas1> (long)
[09:38:33] <Tom_itx> you don't like it?
[09:38:40] <Tom_itx> oh
[09:39:01] <anonimas1> can only have like 300mm tools sticking out from the turret or else the wall will be near
[09:39:39] <anonimas1> i have only 6 toolspots so space is premium
[09:39:47] <anonimas1> i'll build a rear turret someday
[09:39:51] <anonimas1> err second.
[09:39:55] <Tom_itx> bbl, gotta do a few things here
[09:40:18] <anonimas1> got the plc to send serial commands to another plc to handle things like bar pulling too
[09:40:26] <anonimas1> so i can customize whatever i like
[09:40:28] <anonimas1> :)
[09:40:31] <anonimas1> macro b is neat

[12:19:32] <Loetmichel> 120 done, next batch 300
[12:19:48] <r00t4rd3d> how did you dust protect them?
[12:20:00] <r00t4rd3d> just filter material on the fans, openings?
[12:20:10] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=13447&g2_imageViewsIndex=1
[12:21:17] <r00t4rd3d> heh
[12:21:25] <r00t4rd3d> so somewhat dust protected :)
[12:22:21] <Loetmichel> in the aluminium shell is a dust filter like the ones in kitchen exhausts
[12:23:23] <r00t4rd3d> youve blocked off the normal intakes, now it will suck harder on the cracks that are still open
[12:23:59] <Loetmichel> there is nothing blocked. the filter is nearly withoudt drag
[12:24:18] <Loetmichel> and the "ohter cracks" are shut with copper/aluminium foil tape
[12:24:25] <Loetmichel> for EMI reasoins
[12:24:38] <Loetmichel> the filter frame is teh only intakle left ;-)
[12:25:20] <TekniQue> http://www.f1-2000.co.uk/
[12:25:29] <r00t4rd3d> turn one on, take a hand full of saw dust and sprinkle down over top of it then open it
[12:25:30] <TekniQue> some impressive handiwork
[12:26:54] <Loetmichel> r00t4rd3d: did
[12:27:00] <Loetmichel> no holes left
[12:28:47] <mazafaka> How do you fix the coil on the plastic?
[12:33:11] <mazafaka> Oh, it's tape? but is it reliable and durable?
[12:34:55] -!- psha[work] has quit [Quit: leaving]
[12:35:12] <mazafaka> So it creates larger inner pressure usinf air coming through the filter and therefore does not take any dust inside?
[12:35:42] <mazafaka> Why not just super-duper computer with no fans at all? :)

[16:31:47] <JT-Shop> nice
[16:32:53] <anonimas1> i still have micro streaks though, and i dont know why
[16:34:55] <jdh> what's a microstreak? (other than the obvious)
[16:35:08] <anonimas1> a line appearing no a milled surface
[16:35:53] <syyl> a microsteak?

[16:37:28] <syyl> thats bizzare

[16:38:08] <syyl> hm
[16:38:17] <syyl> chips that get cought and pulled trough again?
[16:38:46] <syyl> doesnt look like a systematic error in the surface
[16:39:36] <anonimas1> flood coolant should keep that from happening
[16:39:49] <syyl> mh yes
[16:39:53] <syyl> works at least for me ;)
[16:40:10] <JT-Shop> are you using a dead sharp insert for aluminum?
[16:41:05] <Jymmm> jdh: If a midget gets a boob job, does that still make her a B-Cup in the regular world?
[16:41:28] <anonimas1> no :) im using a carbide insert cutter
[16:41:33] <anonimas1> (at the moment)
[16:41:40] <anonimas1> i'll try a new endmill tomorrow.
[16:42:18] <JT-Shop> they make inserts for aluminum and they are sharp as a razor
[16:42:27] <JT-Shop> and leave a nice finish
[16:42:44] <syyl> we might call it mirror finish
[16:42:56] <syyl> or get a good endmill for aluminum
[16:45:50] <syyl> with no or a special coating for aluminum...
[16:46:43] <anonimas1> theese inserts are of grade f40m
[16:47:16] <anonimas1> for steel and superalloys :D
[16:47:49] <syyl> mh, almost perfect for aluminum ;)

[18:01:46] <Tom_itx> did you get your ball end made?
[18:01:57] <JT-Shop> no, I've been sidetracked
[18:02:09] <Jymmm> archivist: There is no room for paper, not even folded, rolled, curled, not bigger, not smaller, no green eggs and ham.
[18:02:20] <Tom_itx> i have a couple files if you wanna look at em. one is a finish cut and the other is 3 or 4 passes and a finish cut
[18:02:28] <JT-Shop> sure
[18:02:31] <Tom_itx> i wasn't sure how big a cut you were taking
[18:02:38] <JT-Shop> CAM cutter comp?

[18:02:51] <Tom_itx> it's only the ball end, not the thread end
[18:03:22] <JT-Shop> right the thread end is made first then the screwed into the fixture
[18:03:29] <JT-Shop> then the ball end it turned

[18:06:15] <Tom_itx> i'll post an image of what i have as well. set zero to the end of the ball z is the centerline
[18:06:22] <Tom_itx> err x is
[18:06:57] <Tom_itx> why do you need comp?
[18:08:01] <JT-Shop> I don't need comp, just asked the question wrong I guess
[18:08:39] <Tom_itx> posting image..
[18:09:09] <Tom_itx> if i had a gcode file for your lathe i could fix the template

[18:12:49] <Tom_itx> JT-Shop, would you rather start cutting from the left and finish at the ball?
[18:13:02] <Tom_itx> i wasn't sure
[18:13:08] <Tom_itx> it's an easy fix
[18:13:45] <Tom_itx> also how big a step over do you make on each pass?
[18:13:59] <Tom_itx> i think i went .015 over the initial radius comp
[18:14:42] <Tom_itx> the toolpath shown follows the nose radius centerpoint
[18:15:06] <archivist> I would start right and cut left due to material strength reasons
[18:15:39] <Tom_itx> well i did
[18:15:57] <Tom_itx> but the ball tip may finish better if you went the other way, i'm not sure
[18:16:36] <Tom_itx> oh, JT-Shop also what's the hex material size? i figured 3/8"
[18:17:33] <Tom_itx> it's using constant surface speed mode so the S and F are probably way off

[18:21:19] <Tom_itx> it should be ok anyway. it was .365 or so. i can repost if you want
[18:21:34] <jthornton> no, that's fine
[18:22:00] <Tom_itx> how big a cut were you taking on the initial cuts?
[18:22:20] <jthornton> 0.020"
[18:22:22] <Tom_itx> i can change that easily too
[18:22:27] <Tom_itx> it's .015 in the model
[18:23:05] <Tom_itx> what feed / speed are you using on it?
[18:23:30] <jthornton> iirc 3k and 2ipm
[18:23:47] <Tom_itx> what's G92 do to that?
[18:23:53] <Tom_itx> i wasn't sure

[18:34:54] <jthornton> that doesn't look correct the left edge should be at 87 degrees not 93
[18:35:14] <jthornton> looks pretty much like my path
[18:35:34] <Tom_itx> lemme see if i can change it, still learning about setting the tool geometry

[18:49:07] <Tom_itx> yeah a tiny bit

[23:05:45] <gene77> Hi Guys; problem with face.py, will not write output file or transfer to linuxcnc. Fix available?
[23:05:52] <Tom_itx> were you gonna run that code or just compare it?
[23:05:59] <Tom_itx> just curious how it did
[23:06:09] <JT-Shop> do you have Axis loaded when you run face.py?
[23:06:16] <gene77> yes
[23:06:16] <JT-Shop> Tom_itx: working on it now
[23:06:39] <JT-Shop> does it give you the option to "Save to Axis" or something like that?
[23:07:44] <gene77> I set the default dir to/home/gene/linuxcnc/nc_files, did help. It can see other files when it open the filename dialog though (no, just write to file)
[23:08:35] <JT-Shop> did you run face.py "from Axis"? via file open in Axis I think
[23:08:53] <gene77> I set the default dir to/home/gene/linuxcnc/nc_files, did not help. It can see other files when it open the filename dialog though (no, just write to file) yes, ran it from axis
[23:09:43] <JT-Shop> did you set the filter option in the ini file?
[23:10:06] <andypugh> halrun
[23:10:13] <gene77> I think so, but lemme check, that was yonks ago.
[23:10:15] <andypugh> Wrong window..
[23:11:22] <JT-Shop> Tom_itx: your using the K offset in the G18 plane only I and J is valid in G18

[23:14:27] <JT-Shop> .tmp is a hidden directory
[23:14:30] <Jymmm> /var/tmp
[23:14:48] <gene77> right, ls -la doesn't show in in my home dir
[23:15:50] <JT-Shop> I just ran face.py from axis and it works
[23:15:59] <gene77> That tmp in /var is owned by root, useless to me
[23:16:10] <Jymmm> gene77: type: env<enter>
[23:16:20] <Tom_itx> JT-Shop does the J correlate to the z move?
[23:16:33] <Tom_itx> x to I and z to J?
[23:16:35] <JT-Shop> when you open it from Axis if you don't see "Write to Axis" it doesn't know Axis is alive
[23:16:53] <JT-Shop> I = X J = Z
[23:16:59] <JT-Shop> yep

[23:19:45] <JT-Shop> gene77: does the bottom right button say "Quit"?
[23:19:53] <gene77> yes
[23:19:54] <Tom_itx> JT-Shop wouldn't M5 work the same on a lathe?
[23:20:01] <gene77> yes
[23:20:05] <JT-Shop> then it does not know Axis is alive
[23:20:16] <Tom_itx> i wonder why they didn't just do that
[23:20:23] <gene77> but axis ran it!
[23:20:48] <andypugh> Tom_itx: T000000 turns off tool offsets and unlads the tools on some lathes, I think
[23:20:54] <Tom_itx> oh
[23:21:03] <andypugh> halrun
[23:21:03] <JT-Shop> it looks for something specific just a sec
[23:21:06] <Tom_itx> yeah i spoke too soon i was referring to S0000
[23:21:08] <andypugh> Did it agai
[23:21:10] <Tom_itx> sry
[23:21:10] <andypugh> n
[23:21:12] <gene77> and it looks like /var/tmp is wide open for perms, and I do own a couple of files in it.
[23:21:38] <joe9> i home the machine everytime I start it up. Is that common? or, is there anyway that I can save the x,y,z values between restarts?
[23:21:42] <Connor> okay, so, I want to start working on the hal config and stuff for a ATC..
[23:21:58] <JT-Shop> that doesn't have anything to do with it "seeing" axis
[23:22:06] <Connor> can anyone give me USEFUL info on that
[23:22:20] <Connor> for toolchanges.. I.E. a sample hal file or something..
[23:23:02] <JT-Shop> gene77: it looks for IN_AXIS = os.environ.has_key("AXIS_PROGRESS_BAR")
[23:23:56] <gene77> John, would this be related to isolcpus? How the heck do I add that to my ini?
[23:23:59] <JT-Shop> joe9: homing after a power cycle is normal also after using the e-stop on a stepper machine
[23:24:53] <joe9> JT-Shop: thanks.
[23:25:02] <Connor> anyone? :)
[23:25:42] <JT-Shop> gene77: I don't think it is related to either one
[23:25:50] <andypugh> Connor: It's complicated
[23:25:56] <andypugh> What sort of ATC?
[23:26:13] <gene77> ISTR I saw something along those lines in the wiki, might be a starter guide anyway
[23:26:23] <Connor> andypugh: I know. To start off, a simple rack at the end of the table.
[23:27:14] <gene77> and the env, from another term session, has no such string in its env John
[23:27:31] <JT-Shop> gene77: if you go File > Open in Axis then navigate to face.py and open it does a spinner replace the mouse pointer when over Axis?
[23:27:38] <Connor> which means, I'll have different positions for each tool.. later on.. it'll be a carousel or some other form that will only require 1 position.
[23:27:44] <gene77> lemme check
[23:27:55] <JT-Shop> gene77: are you running axis from a terminal?
[23:28:07] <gene77> yes John
[23:28:15] <gene77> yes again
[23:28:37] <JT-Shop> I wonder if that has anything to do with it?
[23:28:46] <andypugh> well, http://www.linuxcnc.org/docs/devel/html/remap/structure.html is the docs, and in master there is an example config in sim/remap/rack-tolchange
[23:28:49] <JT-Shop> can you run it from the CNC menu?
[23:29:58] <JT-Shop> no, I just ran axis sim from a terminal and worked fine.
[23:30:02] <Connor> What version of linuxcnc is that ?
[23:30:10] <andypugh> Connor: Master
[23:30:17] <Connor> my sim doesn't have sim/remap
[23:30:34] <JT-Shop> gene77: split in half and run the Axis sim and then face.py to see if something is borked on your config
[23:30:48] <andypugh> Connor: Which version are ou on?
[23:31:30] <Connor> 2.5.0 SIM and 2.5.2 or something on my mill.
[23:31:32] <JT-Shop> dang that was 4 years ago that I wrote that LOL
[23:31:36] <gene77> I can run it from the menu, and I can run it from the launcher icon, no change in the quit buttom lower right corner
[23:31:51] <JT-Shop> try running the Axis sim
[23:31:54] <Connor> was going to get the basic config working in the sim then port it over to the machine
[23:31:59] <JT-Shop> someone is in a time warp
[23:32:04] <andypugh> Connor: You need a 2.6 version. Toolchange is so much simpler with remap
[23:32:39] <Connor> okay. What's the easiest way to upgrade both my SIM and my main machine? and will I break anything? :)
[23:32:50] <andypugh> It is basically too much of a game to move the machine axes during toolchange prior to that.
[23:33:02] <andypugh> Connor: Buildbot
[23:33:11] <andypugh> buildbot.linuxcnc.org
[23:33:43] <Tom_itx> JT-Shop do you use G96 (Constant Surface Speed) on your lathe?
[23:33:57] <andypugh> And try not to break it, but don't guarantee not to.
[23:34:00] <gene77> sim version is not in the,nu
[23:34:09] <gene77> sim version is not in the CNC menu
[23:34:31] <Tom_itx> the S word is a constant surface speed in feet per minute instead of spindle speed i believe
[23:34:43] <Connor> okay, so I take it master is the 2.6 dev branch
[23:34:50] <andypugh> Aye
[23:35:06] <andypugh> Try the sim on the sim machine first
[23:35:15] <Connor> okay.. so, I'm on 10.04
[23:35:19] <Tom_itx> damn i'm gonna have to get the book out
[23:35:29] <andypugh> ?
[23:35:39] <Connor> looking to figure out which build to grab..
[23:35:51] <JT-Shop> Tom_itx: most of the time except for drilling, tapping, and tiny things
[23:35:58] <Tom_itx> andypugh i'm trying to mod a lathe template
[23:36:16] <JT-Shop> seems face.py is a bit ill behaved if you want to save to a file if you launched it from axis
[23:36:35] <Tom_itx> JT-Shop, their format is wrong anyway for it acording to the linuxcnc docs
[23:37:19] <Tom_itx> i need to add a parameter and change the S speed to D speed and add the rate as the S word
[23:37:21] <gene77> You are shooting for the understatement of this half hour? :)
[23:37:23] <andypugh> Connor: deb http://buildbot.linuxcnc.org/ lucid master-sim
[23:37:23] <JT-Shop> that something you change in the template?
[23:37:31] <Tom_itx> i can
[23:37:50] <Tom_itx> it's very flexible
[23:37:55] <Tom_itx> it's all in the knowing how
[23:37:57] <JT-Shop> gene77: I mean face.py doesn't give you a graceful way to exit if you save to a file
[23:37:59] <Tom_itx> and i'm rusty
[23:39:09] <andypugh> Tom_itx: Bathing in Diet Coke will help
[23:40:30] <JT-Shop> or caustic soda
[23:40:31] <gene77> I'll be, I found the file, it put it in the $conf dir!
[23:40:42] <Tom_itx> i have quite a few i could choose from. dynapath, cn102x (whatever that is), mazak, okuma and about a dozen others
[23:40:57] <gene77> wtf?
[23:41:53] <gene77> A couple hdogs just arrived, time out for 10 min
[23:42:00] <Tom_itx> fanuc 6t
[23:42:02] <JT-Shop> what file
[23:42:18] <JT-Shop> I thought you said a couple of hogs
[23:43:11] <gene77> the output file
[23:43:33] <gene77> i told it told it to write
[23:43:39] <JT-Shop> did you set the NC file directory?
[23:44:05] <JT-Shop> still puzzles me why face.py can't see that Axis is alive
[23:44:08] <gene77> yes, right where it is...
[23:44:58] <Connor> okay. got the 2.6 build on my sim machine.
[23:45:09] <Connor> now how do I get the remap stuff ?
[23:45:12] <JT-Shop> when go to CNC Linuxcnc the sims don't show up?
[23:48:31] <andypugh> Connor: It's just there, the sim/remap/rack toolchange should work
[23:48:57] <Connor> found it.. it's having issues runnning.. can't find ../../core_sim.hal
[23:48:58] <andypugh> Oh, ah, well, <puzzled>
[23:49:30] <andypugh> Ah, yes, you know I couldn't find that file earlier.
[23:49:40] <andypugh> let me experiment
[23:49:48] <Connor> it's in the Axis directory though..
[23:50:01] <Connor> needs to be looking in ../../axis maybe ?
[23:51:38] <gene77> nother one, I ran python path-to-face.py, set the nc_directory, but when I went back to look, still in the same invocation, it had defaulted to /home again. So it is not saveing that pref
[23:54:31] <JT-Shop> gene77: you running 2.5?
[23:54:35] <gene77> yes
[23:55:04] <JT-Shop> and you don't see any sample configs when you run CNC > LinuxCNC to pick from?
[23:55:06] <gene77> latest build I think, but the buildbot hasn't offered a new one in a week or so.
[23:55:29] <Connor> okay.. what the heck is toplevel.py ?
[23:55:40] <gene77> No samples, just the ones I've made over the years
[23:56:37] <andypugh> Connor: It is actually in configs/common/core_sim.hal
[23:56:49] <gene77> My back is telling me to stick a fork in it, its done, see you all on the ML later.
[23:57:09] <JT-Shop> ok
[23:57:21] <Connor> I don't have a configs/common
[23:57:51] <andypugh> Not at all?
[23:57:56] * JT-Shop listens to Autobahn by Kraftwerk
[23:57:59] <andypugh> Or not in the config tree?
[23:58:17] <Connor> not in my ~/linuxcnc/configs/
[23:59:03] <andypugh> No, it is probably hiding in /usr/linuxcnc/docs or somewhere equally stupid
[23:59:39] <andypugh> You might need to find it and copy it to somewhere useful. Welcome to the Bleeding Edge "-(
