| 00:21.19 | Maloeran | So I'll have to be in Maryland next friday. Is there any snow left down there? Is the weather clean for bicycles? |
| 00:23.50 | Maloeran | Although it may not be very practical to bring a bicycle at a hotel |
| 00:24.48 | Twingy | there is about half an inch of sleet on the ground |
| 00:25.23 | Maloeran | Yuck. |
| 00:28.58 | Twingy | definetly no flying this weekend |

| 01:06.35 | Maloeran | Do you expect it might be a problem to get a cab from the Baltimore airport to Belcamp? Is it too far away? |
| 01:07.32 | brlcad | it's about a 45-65 minute drive, cost about $50 iirc |
| 01:08.14 | brlcad | there are vans, taxis, shuttles that run all the time |
| 01:08.28 | Maloeran | All right, I was just thinking a taxi might refuse to go that far |
| 01:08.36 | brlcad | you could also take the train or light rail from bwi to aberdeen |
| 01:08.48 | brlcad | nah, they do it all the time |
| 01:08.54 | Maloeran | *nods* Great |
| 01:09.31 | brlcad | might want to schedule it with them beforehand though, you can make a reservation |

| 01:59.43 | Maloeran | Worse!... IriX64s are like duct tape, one never has quite enough |
| 02:00.14 | IriX64 | ill see about mitosis then :) |
| 02:02.16 | IriX64 | so ./configure is the preffered approach? |
| 02:05.39 | Maloeran | Prefered approach for what? |
| 02:08.19 | IriX64 | building brlcad, i was told the more i put on the command line, the less you support me :) |

| 02:31.40 | IriX64 | Maloeran: I'm uneducated what the heck is an opteron? |
| 02:31.49 | dli | Maloeran, enough time to compile openoffice from source :( |
| 02:34.01 | Maloeran | If only so, dli, my laptop battery lasts a hour. I'll have to stock up on batteries |
| 02:34.23 | Maloeran | IriX64, server-class variant of your processor, optimisation rules for GCC are the same |
| 02:34.54 | IriX64 | ty i learned something... you (whatever) you learn. |
| 02:34.55 | dli | Maloeran, you mentioned 2 stops, you have chance to plugin and charge |

| 17:24.31 | Twingy | I just made the stock |
| 17:24.59 | IriX64 | interesting your gcam is NC stuff? |
| 17:25.17 | Twingy | jes |
| 17:25.22 | IriX64 | ermf X comes up ogl coredumps, go figure |
| 17:25.58 | IriX64 | I took care of a vax doing train wheels at the plant interesting lathes they have. |

| 17:26.59 | Twingy | wait till you see the chip amps he built that go inside |
| 17:27.21 | louipc | not bad eh |

| 17:28.45 | IriX64 | shaper? |
| 17:28.48 | Twingy | yep |
| 17:28.52 | Twingy | cnc mill |
| 17:29.04 | louipc | I guess the tolerance isn't too critical for those |
| 17:30.34 | IriX64 | nice machines those can toll down to .0001 |
| 17:30.34 | IriX64 | err .001 |
| 17:30.34 | louipc | .0001 inch |
| 17:30.34 | IriX64 | :) |
| 17:30.35 | louipc | is standard |
| 17:30.35 | IriX64 | mines old :) |
| 17:30.35 | louipc | for cnc |
| 17:30.35 | Twingy | the machine will provide 0.00003125 tolerance |
| 17:30.35 | Twingy | 1 / (8 * 20 * 200) |
| 17:30.35 | IriX64 | Twingy please the stuff i played with was 30 years ago. |
| 17:30.46 | IriX64 | and i dont trave in the ms very often unless trouble comes up. |
| 17:30.53 | IriX64 | travel too. |
| 17:31.05 | louipc | hah I played with a Minimatic 500 |
| 17:31.17 | louipc | it had the funkmaster flex logo on it |
| 17:31.24 | louipc | no graphical display |
| 17:31.40 | louipc | horizontal CNC mill, pretty damned old |
| 17:32.13 | louipc | it used taped, but it was fitted for code transfer from a computer so I didn't need to worry about that |
| 17:32.13 | IriX64 | we didn't have one |
| 17:32.32 | IriX64 | cincinatti or ohio? |
| 17:32.56 | louipc | japanese |
| 17:34.11 | louipc | you had to manually calculate the tool radius offsets for that too hahh |
| 17:34.44 | IriX64 | pays to take a math course with you're machine shop course :) |
| 17:35.45 | IriX64 | man help me here i have a #ifdef IF_OGL with nothing folowwing it. |
| 17:36.14 | IriX64 | if_ogl.c line 54 |
| 17:36.49 | Twingy | fun, now I can easily make gears |
| 17:37.04 | IriX64 | heh make your own bicycle |
| 17:37.51 | Twingy | jes |
| 17:38.10 | Twingy | I will do a spur gear or sprocket tutorial for next release |
| 17:38.23 | IriX64 | try a worm gear. |
| 17:42.30 | IriX64 | something i'm not groking here if_x has similar but no matching endif or im missing it |
| 17:43.01 | Twingy | worm gear will be easy once I put stuff in for 4th axis |
| 17:43.46 | louipc | hmm I've never done a thread in CAM wonder how that would work |
| 17:43.58 | louipc | a worm gear is just an acme thread yeah? |
| 17:43.59 | Twingy | use a conical or a bull nose |
| 17:44.30 | Twingy | make your helix to make threads per inch, like a common 1/4" 20TPI |
| 17:44.49 | Twingy | then figure out if you want a class 1,2, or 3 fit |
| 17:45.22 | Twingy | the only tricky part is getting it mounted correctly |
| 17:45.56 | louipc | actually now that I think about it it would be pretty simple |
| 17:46.27 | IriX64 | im all wet |
| 17:47.01 | IriX64 | in x ayway you can comment out all if_x with that define:) |
| 17:47.14 | louipc | well TPI is based on feed/rev, the fit is based on internal/external dia, then all you need to define is angle of approach for the different passes |
| 17:47.58 | IriX64 | sigh same for if_ogl |
| 17:52.23 | Twingy | and depth |
| 17:55.29 | IriX64 | if you find /dev/ogl do you want or not want mode to be set to 0? (I know squat about opengl) line 717 if_ogl.c |
| 18:04.49 | IriX64 | is cygtls a TCL think, anybody know? |
| 18:04.56 | IriX64 | thing too |
| 18:44.45 | louipc | but there are canned cycles on cnc lathes for thread turning |
| 19:25.25 | Twingy | but I don't have a cnc lathe |
| 19:25.31 | Twingy | just a 4 axis mill |
| 19:36.16 | Twingy | pattern tool is done |
| 20:21.04 | Twingy | http://js.cx/~justin/images/spur_gear.jpg |
| 20:22.22 | IriX64 | would it be too much to ask for target physical dimensions somewhere on the screen? |
| 20:22.55 | Twingy | the grid isn't enough? |
| 20:23.04 | IriX64 | summary thing |
| 20:23.29 | Twingy | in due time :) |
| 20:23.34 | IriX64 | :) |
| 20:24.44 | Twingy | you would need to use 1/16" end mill for that |
| 20:25.10 | Twingy | otherwise the gear would come out funky looking |
| 20:25.17 | IriX64 | dont know the mill just the computer that drives it. |
| 20:25.41 | Twingy | jes, but the mill requires a cutting tool |
| 20:25.50 | Twingy | and it needs to be the right size |
| 20:26.03 | IriX64 | ah got it i call it a bit |
| 20:26.42 | IriX64 | mmm thats a lathes tool tho right? |
| 20:26.50 | IriX64 | mine i mean. |
| 20:26.51 | Twingy | lathe uses a cutting tool |
| 20:27.02 | Twingy | mill uses and end-mill |
| 20:27.12 | IriX64 | got it |
| 20:27.28 | Twingy | think I will cut a few gears when I get my cnc back |
| 20:27.37 | Twingy | broach them as well |
| 20:27.46 | IriX64 | broach? |
| 20:27.51 | Twingy | yes, broach a key way |
| 20:28.08 | IriX64 | don't know the term broach |
| 20:28.30 | Twingy | can either broach a key way and 2 collars, or broach a key way with a set screw |
| 20:29.33 | Twingy | I wonder if I can make gears for my servos with 1/50" end mill |
| 20:30.17 | IriX64 | thats a fine tool |
| 20:30.20 | Twingy | that gear is 3,651 lines of g-code |
| 20:30.46 | IriX64 | you just punch that out and feed it to the machine? |
| 20:30.54 | Twingy | yep |
| 20:31.10 | Twingy | run it with a 1/16" at 1.5 ipm 6.5k rpm |
| 20:31.20 | Twingy | probly take 3 or 4 hours to cut |
| 20:31.55 | IriX64 | the bigger the end mill the longer right? do i understand that? |
| 20:32.01 | Twingy | nope |
| 20:32.08 | IriX64 | other way? |
| 20:32.11 | Twingy | you can buy any end mill imaginable |
| 20:32.39 | Twingy | you will snap longer ones easier if you don't know what you are doing |
| 20:32.51 | Twingy | or damager your machine if > 1/8" or so |
| 20:32.54 | Twingy | *damage |
| 20:33.00 | IriX64 | i meant longer timewise |
| 20:33.09 | Twingy | depends on the steppers |
| 20:33.13 | Twingy | and the spindle speed |
| 20:33.30 | IriX64 | your g-cam calculates those obviously |
| 20:33.42 | Twingy | if you are 40k rpm, vertical mill, with 800oz-in steppers and coolant, cut through Al like butter |
| 20:33.54 | IriX64 | ah |
| 20:33.55 | Twingy | nope, I let the machinist put what they want in |
| 20:34.22 | Twingy | different speeds give different finishes |
| 20:34.31 | Twingy | also do certain wear and tear on the end mill |
| 20:34.41 | Twingy | for a production run you tune this to what you need |
| 20:35.08 | Twingy | after you machine stuff for a while you can usually guess with in 10% of what the most optimal value will be |
| 20:35.15 | Twingy | for that specific machine |
| 20:35.21 | Twingy | for a different machine, totally different |
| 20:35.31 | IriX64 | get to know your equipment huh? |
| 20:35.36 | Twingy | the taig, yep |
| 20:35.48 | Twingy | this isn't like ray-tracing |
| 20:35.55 | Twingy | where you press a big red button and it does its thing |
| 20:36.15 | Twingy | it's a little more intimate than that |
| 20:36.18 | IriX64 | is g-cam what am i trying to say here whats the status of g-cam? |
| 20:36.28 | IriX64 | readiness wise |
| 20:36.32 | Twingy | it's stable |
| 20:36.37 | Twingy | as of last 2 releases |
| 20:36.39 | IriX64 | good job |
| 20:36.46 | Twingy | not bug reports as of last release |
| 20:36.47 | Twingy | *no |
| 20:36.53 | Twingy | just feature requests |
| 20:37.08 | IriX64 | enjoy :) |
| 20:37.11 | Twingy | got a $32 donation last night |
| 20:37.46 | Twingy | now I will start building up a part library |
| 20:37.47 | IriX64 | people used to send me donations for my not-for-profit bs years ago |
| 20:37.55 | IriX64 | *bbs |
| 20:38.06 | Twingy | gears, sockets, mounts, etc |
| 20:38.53 | Twingy | make them available on the wiki |
| 20:38.53 | Twingy | would be nice to see a generation of open source hardware made available in gcam |
| 20:38.58 | Twingy | electronics and mechanical |
| 20:56.34 | clock_ | Twingy: I have some open source hardware but unfortunately it isn't done in gcam http://ronja.twibright.com |
