| 10:02.26 | chinamill | is there any nice support of making toolpaths and export to g-code with brlcad? |
| 13:10.53 | ``Erik | I don't believe so... one of the developers was working on a seperate tool called "gcam" to generate gcode... |
| 13:12.30 | ``Erik | http://gcam.js.cx/ |
| 13:47.58 | chinamill | Thanks for the tip Erik! |
| 15:18.03 | brlcad | chinamill: i can corroborate that as well.. there's not a means to directly export g-code with brl-cad right now, would be cool if someone added the support but it's not a trivial task and not high on the priority list atm |
| 15:18.54 | *** join/#brlcad cradek (n=chris@pdpc/supporter/active/cradek) |
| 15:19.07 | brlcad | hello cradek |
| 15:19.11 | cradek | hi all |
| 15:20.00 | cradek | I'm a newbie to brlcad, and sorry if everyone says this, but I'm having problems compiling it, is there documentation other than http://brlcad.org/build_CVS.html I should be looking at? |
| 15:20.25 | brlcad | cradek: definitely -- see the INSTALL file for more comprehensive install instructions |
| 15:20.25 | cradek | (I get an autoheader failure from autogen.sh in step 2) |
| 15:20.48 | brlcad | there may also be a doc/README.[some_platform] file for your system with some details too |
| 15:21.06 | brlcad | autoheader failure.. wow |
| 15:21.27 | brlcad | run ./autogen.sh --verbose |
| 15:21.49 | cradek | running, I'll put the output on pastebin |
| 15:24.01 | cradek | http://pastebin.dyndns.org/305 |
| 15:24.03 | brlcad | for what it's worth, autogen.sh failure generally just means there's something wrong with your installed build tools (like an insufficient version of something in the GNU build system) |
| 15:24.22 | cradek | I am a longtime unix developer but have little experience with auto tools |
| 15:24.26 | brlcad | strictly speaking, if you're working from a source distribution (non-cvs), then you shouldn't need to run autogen.sh |
| 15:24.51 | brlcad | i.e. if you have a big ass configure file in the top level, then you probably don't need to run autogen.sh |
| 15:25.09 | brlcad | autogen.sh is only required if you've checked out from cvs or really just want to fully "start fresh" |
| 15:25.15 | cradek | ok, I am using cvs so far, if this isn't easy to fix I'll use a source distribution |
| 15:25.33 | chinamill | there is no rpm:s or similar? |
| 15:26.04 | brlcad | ahh.. configure.ac:1: error: possibly undefined macro: dnl |
| 15:27.05 | brlcad | that means autoconf install is somehow hosed or exceptionally old or running in 2.13 mode |
| 15:27.28 | cradek | Checking autoconf version: autoconf --version |
| 15:27.28 | cradek | Found GNU Autoconf version 2.59 |
| 15:28.00 | brlcad | this wouldn't happen to be debian sarge would it? |
| 15:28.07 | cradek | ubuntu 5.10 breezy |
| 15:28.14 | cradek | so ... sort of |
| 15:28.32 | brlcad | debian used to have a very broken autoconf wrapper script |
| 15:28.50 | brlcad | if you ran it directly, it would report the right version, then proceed to invoke the 2.13 autoconf |
| 15:29.19 | brlcad | that's sort of what seems like is going on here too |
| 15:29.54 | brlcad | another possibility is that you're simply missing the .m4 files for autoconf |
| 15:30.18 | cradek | I'll remove the autoconf2.13 package and hope for the best then |
| 15:30.28 | brlcad | if you have any other system that you can run autogen.sh on, that would also work -- it doesn't have to be run on the same machine, it can be run on any machine |
| 15:31.49 | brlcad | have to run out for a bit, bbl if you still have more issues autogen.sh'ing |
| 15:32.14 | cradek | no change when I remove autoconf2.13 |
| 15:32.45 | brlcad | then it must be some other misconfiguration (like the misplaced/uninstalled m4 files) |
| 15:33.23 | brlcad | someone in #ubuntu might have an idea as it used to be incredibly frequent when sarge was popular |
| 15:33.36 | cradek | ok thank you |

| 16:28.06 | ``Erik | twingy, you dont' have any wintergreen oil, do you? |
| 16:29.17 | Twingy | no |
| 16:29.41 | Twingy | got some WD40 though |
| 16:30.03 | ``Erik | tried it, bolts won't budge |
| 16:30.18 | Twingy | use a can of coke? |
| 16:30.40 | ``Erik | haven't tried that yet... supposedly wintergreen is the best, and vinegar is really good, with coke being somewhere below vinegar |
| 16:30.47 | Twingy | if you can figure out a way to let them soak in a pan for 30 minutes |
| 16:31.04 | Twingy | duct tape it, whatever |
| 16:31.14 | ``Erik | so I'm thinking about taking a cup of vinegar out with a brush, or mebbe rubber banding a soaked paper towel |

| 16:32.14 | fenn | making parts :) |
| 16:32.20 | ``Erik | and my dad was a jet mechanic for 20 yrs and a car mechanic before that, so I kinda trust him when he says wintergreen is the hshizzle forrizle |
| 16:32.35 | ``Erik | parts for what? :) |
| 16:33.13 | fenn | well, a cnc machine, some hydraulic valves for a robot, turbine engine parts, foam cores for composite layup |
| 16:33.20 | fenn | and on and on and on |
| 16:33.47 | ``Erik | hobbyist? or work? (if you dont' mind my asking) |
| 16:34.01 | fenn | i'm self employed but i dont make any money.. how's that |
| 16:34.19 | ``Erik | ah, heh... "interested student" ;) *duck* |
| 16:34.46 | fenn | though honestly gcam is not doing things the way i would have done them |
| 16:34.59 | ``Erik | huh, mind if I ask? |
| 16:35.36 | fenn | well the heart of a cam system is the toolpath planning algorithms |
| 16:36.04 | fenn | he seems to be starting off with basic stuff like 3d rendering |
| 16:36.28 | ``Erik | hm, 3d rendering, or basic object description? |
| 16:36.56 | ``Erik | <-- kinda thinks that tool path is one of those problems that the machine can solve and optimize, just tell it what shape you want to have and let it figure the way to make it... |
| 16:38.09 | fenn | i just think it would be smarter to use an already existing library for the 3d data structures and math |
| 16:38.52 | fenn | that's why i was asking all these questions about brlcad's libbn and such |
| 16:40.02 | ``Erik | math is well understood and reasonably easy to implement, tho... I mean, you can slap together solid vector and matrix functions in half a day of mindless work, so why induce a dependancy? |
| 16:40.12 | fenn | lol |
| 16:40.21 | ``Erik | <-- very much likes the idea of libraries, btw, is playing devils advocate |
| 16:41.27 | fenn | is there any interest in STEP import for brlcad? |
| 16:41.56 | ``Erik | in a decent operating system with a decent software install concept, dependancies are a non-issue... on fbsd, just type "make install" and it does it's think... :) I wouldn't mind seeing tcl and tk and itcl/itk, libpng, libz, etc ripped out of the brlcad distro... |
| 16:42.07 | ``Erik | what's "step"? I'm quite ignyant on these things, btw... |
| 16:42.23 | fenn | the file format to end all file formats |
| 16:42.29 | ``Erik | my major contribution so far has been redoing the build system, I don't have the foggiest clue how to model shit :) |
| 16:42.46 | ``Erik | that sounds... slightly biased. |
| 16:42.56 | fenn | for cad systems, it's sorta XML and is extendable to cover all aspects of cad/cae/cam |
| 16:43.23 | ``Erik | although I'm quite sure if someone were to provide the g-step and step-g program patch... it would be appreciated :) |
| 16:43.33 | SWPadnos | fenn, have you actually seen a STEP file spec? (I thought you had to pay, like ISO standards) |
| 16:43.59 | fenn | SWPadnos: there is a free "express schema" which is the basic xml description |
| 16:44.05 | SWPadnos | ah, OK |
| 16:44.08 | fenn | and also you can get preliminary standards for free |
| 16:44.18 | fenn | i havent actually sat down and looked at either of them |
| 16:45.05 | fenn | there is a nist project to convert express to xml |

| 20:19.52 | brlcad | seems as though much of #emc woke up today and decided to go on a field trip .. |
| 20:21.02 | dan_falck | hi brlcad |
| 20:21.08 | dan_falck | yes we did |
| 20:21.26 | dan_falck | we are interested in gcam, which we think is related to brlcad |
| 20:21.48 | dan_falck | fenn and SWPadnos probably are very interested |
| 20:21.55 | dan_falck | cradek too |
| 20:22.14 | dan_falck | Twingy, is gcam your program? |
| 20:22.23 | brlcad | not really related to brl-cad other than it's Twingy's project and he's somewhat related to brl-cad ;) |
| 20:22.34 | dan_falck | ok |
| 20:22.44 | dan_falck | fenn, did you get that? |
| 20:22.49 | brlcad | i.e. it shares no code or functionality, doesn't link to any of brl-cad's libs last I looked unless he changed something :) |
| 20:23.29 | dan_falck | how are you doing these days? |
| 20:23.37 | brlcad | pretty well, keeping busy |
| 20:23.59 | dan_falck | same here. Taking a short break from building a deck |
| 20:24.13 | brlcad | the blasted windows port took up an enormous amount of time, just starting to get back into more useful development |
| 20:24.31 | dan_falck | we still don't use windows at the shop where I work |
| 20:24.35 | dan_falck | OS X |
| 20:24.39 | dan_falck | and linux |
| 20:24.44 | brlcad | likewise |
| 20:24.59 | brlcad | cept for the desk junkies, analysts |
| 20:25.13 | dan_falck | makes it hard to find a CAM program, hence the intense interest in anythin cam related |
| 20:25.15 | brlcad | but not the modelers, developers, and other tech |
| 20:25.37 | dan_falck | the owner of our company said that we would NEVER use windows |
| 20:25.42 | dan_falck | and so far so good |
| 20:25.46 | brlcad | yeah, i was talking to him about making his g-code thing a more general purpose library so that I could hook into it in brl-cad |
| 20:25.53 | dan_falck | cool |
| 20:26.21 | brlcad | well, it would be cool -- depends how much interest gcam in general gets will probably determine if he does |
| 20:26.51 | fenn | sorry i was ignoring irc due to a troll on another channel |
| 20:26.58 | brlcad | yay, trolls |
| 20:27.06 | dan_falck | probably about 20 people from #emc would be interested |
| 20:27.20 | brlcad | how many of those 20 are users and how many are devs? :) |
| 20:27.24 | fenn | ooo yes i wouldnt mind getting my hands on the "real" standard |
| 20:27.38 | fenn | i've been drowning in complicated standard draft documents all day long |
| 20:27.48 | brlcad | fenn: heh, you and half the industry |
| 20:27.58 | fenn | its only like $60 isnt it? |
| 20:28.07 | brlcad | those damn standards are rather expensive for just about any non-commercial use |
| 20:28.14 | dan_falck | fenn could probably tell you how many are developers in the EMC group |
| 20:28.32 | fenn | there are really only like 5 or 6 active developers |
| 20:28.59 | fenn | everyone's in the same boat though |
| 20:29.13 | brlcad | fenn: i forget the details, but the 5 or 6 APs of STEP that I have were somewhere in the 1-2k range, iso lists the costs iirc |
| 20:30.00 | brlcad | which is one part how it's cool that we at least have them to go on, makes it a heck of a lot easier to make an open source library out of them in a manner that anyone could then use |
| 20:30.13 | brlcad | without needing to buy their own copy |
| 20:30.42 | fenn | oh wow |
| 20:30.56 | dan_falck | fenn: so now we know that gcam is Twingy's program. |
| 20:31.19 | fenn | ap203 and ap214 are the ones i was interested in |
| 20:31.25 | fenn | and step-nc whatever that is |
| 20:31.36 | fenn | looking at the file format it doesnt seem too complicated really |
| 20:31.40 | brlcad | to get the COMPLETE iso spec for STEP, it's roughly in the 10-15k range and would fill at least one 20' library shelf if printed |
| 20:31.50 | fenn | its all the buzzwordage that is hard to dig through |
| 20:32.09 | brlcad | 203 and 214 are by far the most interesting, though little ones like 11 and 21 become handy when writing a parser |
| 20:32.53 | fenn | i would like to make a portable library that could be used in more than just brlcad |
| 20:33.34 | brlcad | it's a shame that the dev that was working on it ran off, he was making good progress |
| 20:34.26 | brlcad | had taken over the nist parser, updated to the latest step spec, got it working more cross-platform, got it parsing some example step files |
| 20:34.52 | fenn | it wasnt terry hancock was it? |
| 20:34.56 | brlcad | all pretty low level still, no hook functionality |
| 20:35.15 | fenn | i've been reading this over and over, trying to psych myself up: http://www.freesoftwaremagazine.com/articles/free_matter_economy_4?page=0%2C2 |
| 20:35.41 | brlcad | heh, it was a terry |
| 20:35.46 | fenn | awesome |
| 20:35.53 | brlcad | but afaik, his last name wasn't hancock |
| 20:36.07 | brlcad | ridder according to sf project account |
| 20:36.11 | fenn | oh |
| 20:36.29 | fenn | he wrote a bunch of stuff about a "gnu cad/cam" a long time ago |
| 20:37.10 | brlcad | vaguely remember |
| 20:37.29 | brlcad | i've read some other stuff from hancock, mostly good ideas but definitely not ridder |
| 20:37.32 | fenn | oh man sourceforge is so pathetic |
| 20:38.10 | brlcad | ridder is a rather bitter guy that doesn't like object oriented designs in general, so somehow I doubt he'd be pushing for a python layer that converts step to xml :) |
| 20:39.12 | brlcad | he seemed to like lower level libraries, straightforward simple C apis |
| 20:39.36 | fenn | i actually dont know which is more appropriate for a file format library |
| 20:40.22 | brlcad | i like and agree with most of hancock's ideas, though there's a reason step wasn't done in xml (and it's not because it predated xml or anything) |
| 20:40.43 | fenn | why is that, do you know? |
| 20:40.49 | brlcad | the spirit of that article I like, though a lot of the technical detail is less than appealing |
| 20:41.16 | fenn | making a new language to describe a file format seems kinda overboard |
| 20:41.25 | fenn | or maybe i'm missing something |
| 20:41.44 | brlcad | several reasons it wasn't but probably the most significant one that comes to mind is that step is effectively meant to be the combination of every CAD/CAM/CADD vendor's needs |
| 20:42.18 | fenn | and xml isnt complex enough? :) |
| 20:42.35 | brlcad | and for a huge subset of those area domains, encoding their data into xml is a non-starter due to utter information explosion (about two orders of magnitude) |
| 20:42.47 | brlcad | express is pretty complicated in itself |
| 20:42.57 | brlcad | but it's somewhat more condensed than xml |
| 20:42.59 | fenn | i thought the schema was just a description of the file format |
| 20:43.36 | fenn | is there like "introduction to the STEP thingy" document somewhere |
| 20:43.48 | brlcad | yeah, there's an AP for it that you can buy :) |
| 20:44.12 | brlcad | there's minimal good on-line resources on step |
| 20:44.30 | brlcad | a few industry articles give an intro on it, should be easily found with a search |
| 20:44.36 | fenn | i've skimmed through 23 out of 1600 folders.. |
| 20:44.50 | fenn | i read some modern machine shop articles |
| 20:45.17 | fenn | in fact i dont even care why they did it |
| 20:45.19 | brlcad | helps if you toss in the numerical standard id |
| 20:45.23 | brlcad | i.e. iso 10303 |
| 20:45.35 | fenn | yeah those 1600 are all about 10303 |
| 20:45.56 | fenn | http://www.tc184-sc4.org/SC4_Open/SC4_Work_Products_Documents/STEP_(10303)/ |
| 20:46.18 | brlcad | http://en.wikipedia.org/wiki/ISO_10303 |
| 20:47.34 | brlcad | ug, sc4 is an iso parrot, that's article's about as well written as the step APs themselves |
| 20:48.21 | brlcad | this one isn't too bad: http://www.mel.nist.gov/msidlibrary/doc/jcise1.pdf |
| 20:49.30 | brlcad | nist has a load of useful information, they dumped a lot of time and resources into step about a decade ago that they have given to the community since |
| 20:49.38 | fenn | hm - the development of step is one of the largest efforts ever undertaken by ISO |
| 20:49.49 | brlcad | i'd believe that |
| 20:50.44 | brlcad | the standard really is utterly enormous and complex as it covers just about every single aspect of dealing with a "product" |
| 20:50.57 | fenn | i've noticed :) |
| 20:51.02 | brlcad | from designing it to creating it to selling and distributing or analysing it, etc |
| 20:51.31 | brlcad | not just the computer geometric representation, that's just one small part of it |
| 20:51.48 | brlcad | (hence the 203 and 214.. there really are hundreds of protocols) |
| 20:54.59 | fenn | sometimes i think they must be joking with some of these flowcharts |
| 20:56.36 | brlcad | sadly, they usually are not |
| 20:57.54 | brlcad | since it's almost entirely industry driven, "most" presentations and write-ups aren't meant to be "easy" or "clear" -- they're worked on by people that are paid to do so and often the more verbose or the more obscure, the better they're doing their job ;) |
| 20:58.19 | fenn | well it makes me laugh regardless |
| 20:58.30 | fenn | maybe i'll feel differently once i get my hands dirty |
| 20:58.50 | brlcad | just seeing the iso spec makes me cry sometimes |
| 20:59.12 | brlcad | reading it makes baby seals die I think |
| 20:59.43 | fenn | do you notice signs of rectal bleeding after a protracted coding session :) |
| 21:00.15 | brlcad | hehe |
| 21:26.41 | Twingy | yea I saw the bike |
| 21:26.51 | Twingy | it'll be a while before its out though |
| 21:27.24 | Twingy | and unless they are using non-standard materials for the proton exchange membrane then it's likely to cost $10k or so |
| 21:27.46 | Twingy | and all that will get you is about 1HP |
| 21:36.24 | brlcad | that's odd.. it's supposed to be shipping already |
| 21:36.42 | Twingy | that would be company suicide |
| 21:36.56 | Twingy | they are looking for manuf partners |
| 21:37.09 | brlcad | it was in a best new product of the year list |
| 21:37.11 | Twingy | and like I said, unless they can figure out how to get rid of the platinum and graphite manuf process... |
| 21:37.23 | Twingy | it's a great product, just not practical from an economic stand point |
| 21:37.38 | brlcad | i'd get one even at 10k |
| 21:37.52 | Twingy | I would to if I had the money |
| 21:37.56 | Twingy | *too |
| 21:37.58 | brlcad | unless it was unusable on the interstate, but it didn't seem like that was the case |
| 21:38.20 | Twingy | wait a few years, a substitute catalyst will be researched |
| 21:38.31 | Twingy | I bet you that bike doesn't exceed 30mph |
| 21:38.33 | brlcad | you'll have it all sorted out by then? :) |
| 21:38.41 | Twingy | me? no, some university |
| 21:38.45 | brlcad | heh |
| 21:39.02 | Twingy | to give you an idea |
| 21:39.06 | Twingy | fuelcellstore.com |
| 21:39.12 | Twingy | look at the prices of those fuel cell stacks |
| 21:39.18 | Twingy | that store skims about 10% off the top |
| 21:39.50 | Twingy | 1 HP on that will get you 25 - 30mph (~750W) |
| 21:40.00 | Twingy | look how much a 750W fuel cell costs |
| 21:40.28 | Twingy | now factor in the cost of the bike and shipping |
| 21:41.07 | Twingy | figure you have some group in china building those for $5/hr |
| 21:41.28 | Twingy | best case scenario you're at $10k in a mass production |
| 21:41.45 | brlcad | most bikes are 10-30k |
| 21:42.05 | brlcad | so for something "high end" niche like this, I wouldn't be surprised if it were 30-50k |
| 21:42.08 | Twingy | you can get many gas crotch rocket bikes for $5-$6k |
| 21:42.15 | Twingy | and they do 100mph, not 25 - 30 mph |
| 21:42.15 | brlcad | not new |
| 21:42.19 | Twingy | yes new |
| 21:42.28 | Twingy | I almost bought a suzuki |
| 21:42.34 | Twingy | I'll pull up the url if you like |
| 21:42.38 | brlcad | nah |
| 21:42.39 | Twingy | I actually sat on it |
| 21:42.44 | Twingy | went to bel air to check it out |
| 21:42.48 | brlcad | for 6k? |
| 21:42.51 | Twingy | right next to the mexican place |
| 21:42.54 | Twingy | $5,995 |
| 21:42.58 | brlcad | that's crazy.. how many cycles? |
| 21:42.59 | Twingy | yellow and blue |
| 21:43.16 | Twingy | they have about 50 in that shop |
| 21:43.33 | Twingy | gets ~50mpg |
| 21:44.09 | Twingy | the #1 problem with fuel cells right now is the catalyst, platinum is just too expensive |
| 21:44.50 | Twingy | I am 100% confident fuel cells will take off, but they need to be re-engineered slightly |
| 21:45.06 | Twingy | they are 2 - 4x more energy dense than lithium polymer batteries |
| 21:45.17 | Twingy | 1800psi - 3200psi respectively |
| 21:46.09 | Twingy | and that's at 50% efficiency (standard) |
| 21:47.10 | Twingy | btw, investing in platinum over the next few years is not a bad idea |
| 21:56.52 | Twingy | time for my run, bbl |
| 23:00.54 | Twingy | back |
| 23:19.04 | dan_falck | Twingy: is gcam yours? |
| 23:20.49 | Twingy | yes |
| 23:21.46 | dan_falck | there are a few of us from the #emc channel interested in it |
| 23:22.02 | Twingy | great |
| 23:22.12 | dan_falck | so august release then? |
| 23:22.13 | Twingy | I use it on my taig cnc |
| 23:22.39 | dan_falck | cool |
| 23:22.50 | Twingy | yea, some time in aug, I'll be doing alot of traveling in the next month, AZ, IL, MA, NJ |
| 23:23.05 | Twingy | 6 weeks actually |
| 23:23.31 | dan_falck | would you be game for a few us playing with it before then? |
| 23:23.57 | Twingy | I can't guarantee it compiles on anything other than freebsd right now |
| 23:24.17 | dan_falck | that's ok. we're used to the challenge |
| 23:24.23 | Twingy | it requires gtk+, opengl, automake/conf |
| 23:24.32 | dan_falck | ok |
| 23:24.48 | Twingy | k, poke me tonight, I've been working through a todo list all day on it |
| 23:24.58 | dan_falck | ok thanks |
| 23:25.15 | Twingy | I'll give you the 5 minute break down on what it is and what it is not |
| 23:25.19 | dan_falck | fenn will be happy too ;) |
| 23:25.22 | dan_falck | ok |
| 23:25.46 | Twingy | don't expect it to rival mastercam or anything, ttyl |
| 23:25.57 | dan_falck | that's ok |
| 23:27.41 | dan_falck | I need to go out and work on the deck. bbl |
