[00:00:00] <Tom_itx> i posted a couple links on that the other day
[00:00:53] <jdhNC> http://www.ebay.com/itm/400265126593
[00:01:00] <jdhNC> kind of shallow though... nice price.
[00:01:45] <Tom_itx> 6" might be ok for my needs
[00:01:57] <Tom_itx> i need to lay stuff out and see though
[00:03:06] <Tom_itx> would you stick the heatsink fins out the side or leave them in and put a fan on them: http://tom-itx.dyndns.org:81/~webpage/cnc/psu/heatsink2.jpg
[00:03:55] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/cnc/psu/driver_wiring.jpg
[00:04:33] <andypugh> Tom_itx: I might just leave them inside with no fan as a Plan A. The box surface area is orders of magnitude greater than that of the components you are trying to cool.
[00:04:47] <Tom_itx> yeah
[00:05:09] <andypugh> Yay! cable lacing: http://www.frobenius.com/bletchley/bl032.jpg Bonus points for naming the device.
[00:05:37] <Tom_itx> holy crap
[00:05:45] <Tom_itx> that's gotta be phone equipment
[00:05:58] <andypugh> No.
[00:06:08] <andypugh> There is a clue in the URL

[00:08:57] <Jymmm> somebody call me?
[00:09:13] <Tom_itx> nope
[00:09:16] <jdhNC> people were calling you names but I told them to stop.
[00:09:18] <andypugh> jdhNC: http://en.wikipedia.org/wiki/Bombe (Or how the Poles won the war)

[00:09:32] <Jymmm> jdhNC: no fun in that
[00:09:41] <Jymmm> andypugh: panduit?
[00:09:56] <Jymmm> never heard of it,
[00:10:08] * Tom_itx gives Jymmm some long shoe laces and sends him off to learn about cable lacing
[00:13:17] <Jymmm> When I worked at ____, one of the amp cabinets was just amazing. you could VISUALLY trace every wire in ever harness from point to point. The harness were self-supported. The water cooling hoses didn't use one clamp and never leaked. It was THE MOST BEAUTIFUL wiring job I have ever seen. Far more a work of art than anything else.
[00:14:59] <Jymmm> The amp was in 3 19" rack type cabinets, so you can imagine how much cabling there was.
[00:16:34] <Jymmm> Does anyone know about themo sealing plastics by chance? Specifically PP

[00:18:32] <andypugh> Jymmm: No, I only know anythng about doing it deliberately.

[01:24:46] <toast2> turns out, kevlar thread is really slippery and doesn't seem to hold knots well
[01:25:25] <Jymmm> toast2: what are you knotting it for?
[01:25:52] <Jymmm> usually used in weaved products that I've seen, then sewn in layers of soemthign else.
[01:26:05] <djdelorie> when I last used kevlar cord, for model rocketry, I made sure all the knots were inside the rocket and embedded in epoxy.
[01:26:25] <Jymmm> djdelorie: for the chute?
[01:26:28] <djdelorie> yup
[01:26:55] <Jymmm> that reminds me, I need to pick up some phenolic
[01:27:04] <ReadError_> hmmm
[01:27:09] <ReadError_> so visualmill is really nice
[01:27:11] <djdelorie> two strands, folded in the middle to make two loops, then the four ends were braided together to form a cord. The end of the cord was deep inside the rocket, leaving only a loop on the outside
[01:27:13] <Jymmm> Gawd that's gonna be expensive
[01:27:13] <ReadError_> i just need to learn it better
[01:27:17] <ReadError_> still my 1st day with it
[01:27:46] <djdelorie> not for the chute cords themselves, for the tether that the shock cord is connected to
[01:27:58] <Jymmm> between each stage?
[01:28:12] <djdelorie> kevlar - shock cord - chute cords - chute
[01:28:17] <Jymmm> k
[01:28:28] <djdelorie> with the nosecone or upper section in there somewhere ;-)
[01:28:50] <Jymmm> you hope =)
[01:29:29] <Jymmm> 3 2 1... clic...SON OF A BITCH! I knew I forgot something *SWISH*
[01:29:44] <Jymmm> too late now gomer!!!
[01:30:28] <djdelorie> http://www.delorie.com/photos/20041002-cmr814/IMG_3980.JPG
[01:30:59] <Jymmm> Yep, there be the *SWISH*
[01:31:23] <djdelorie> that's my biggest, 9 feet tall, three E9 engines
[01:31:23] <ReadError_> anyone here us a ps3 controller as a pendant?
[01:31:28] <ReadError_> i know alex4nder does
[01:31:32] <ReadError_> but anyone else?
[01:33:17] <Thetawaves> djdelorie, i'm surprised you don't make your own motors.
[01:33:44] <djdelorie> there's an excellent write-up in the rec.model.rockets FAQ about why that's a bad idea, written by a friend of mine.
[01:33:52] <Thetawaves> rocket candy is pretty benign, though not so powerful
[01:34:24] <Jymmm> I know where you can get some Potasium Nitrate if so inclined
[01:34:35] <djdelorie> http://www.ninfinger.org/rockets/rmrfaq.5.html#q18
[01:36:10] <Jymmm> djdelorie: Wuss!
[01:36:31] <djdelorie> a wuss with three 160 volt servo motors in his cnc machine :-)
[01:36:42] <Thetawaves> seems like that faq amounts to 'waaaa it's too hard'
[01:36:58] <djdelorie> read the last paragraph
[01:38:10] -!- ve7it has quit [Remote host closed the connection]
[01:39:34] <Thetawaves> most of it's lost on me, i'll be a hundred feet away from it
[01:39:53] <alex4nder> hey
[01:40:29] <ReadError_> hey alex4nder
[01:40:34] <Thetawaves> but i have worked quite a bit with rocket candy and it is ... weak stuff
[01:40:37] <Thetawaves> difficult to light
[01:40:42] <ReadError_> you use the ps3 controller with that qtsixa ?
[01:40:54] <alex4nder> no
[01:40:56] <ReadError_> it sees it, gets the #s and all
[01:41:01] <ReadError_> but i think its for BT only
[01:41:03] <alex4nder> I just use hal_input and X11's joystick
[01:41:14] <ReadError_> got a copy of you config?
[01:41:26] <alex4nder> back in the lab, but it's easy to setup
[01:41:30] <alex4nder> just man joystick
[01:41:33] <alex4nder> and look at the hal_input examples
[01:41:39] <alex4nder> also I'd suggest installing jstest-gtk
[01:42:47] * Thetawaves is one of those guys more interested in how the motor works than how the rocket flies
[01:43:43] <alex4nder> ReadError_: the only thing that's weird is: you need the hid-sony quirk to turn the PS3 controller 'on'
[01:46:57] <ReadError_> finally got some solid toolpaths alex4nder
[01:47:02] <ReadError_> visualmill ;)
[01:47:11] <alex4nder> what's their removal strategy?
[01:47:22] <ReadError_> very flexible
[01:47:24] * djdelorie enjoys the technical challenge of the build
[01:47:29] <alex4nder> ReadError_: but what is it?
[01:47:37] <ReadError_> i have no idea ;)
[01:47:48] <ReadError_> its got a bunch of different options
[01:47:53] <ReadError_> pocketing, profiling, drilling
[01:48:15] <alex4nder> yah, this is where the difference comes into play
[01:48:32] <alex4nder> let me know how it works out
[01:48:38] <alex4nder> if you remember, make some vidoes
[01:49:38] <ReadError_> of the cuts?
[01:49:57] <alex4nder> yup
[01:49:58] <ReadError_> the only thing i cant figure out, is when i home, then touchoff
[01:50:02] <ReadError_> my z is super high
[01:50:07] <ReadError_> but it will still run
[01:50:15] <ReadError_> im using g54
[01:50:29] <alex4nder> where does your CAM reference its zero? top of the material, or bottom?
[01:50:40] <ReadError_> i have it at the bottom
[01:50:52] <alex4nder> and you're touching off Z there?
[01:50:57] <ReadError_> if i have it at the top, it thinks its negative
[01:51:01] <ReadError_> and says nugusta
[01:51:19] <ReadError_> well, z from the top of the material
[01:51:23] <ReadError_> but
[01:51:26] <alex4nder> so what happens if you move Z to where it thinks 0 is, and then touch off with an offset of 0?
[01:51:29] <ReadError_> i have to account for thickness
[01:51:52] <alex4nder> your CAM software is accounting for thickness though, right?
[01:51:52] <ReadError_> well when i say its high, its like out of bounds high
[01:51:55] <ReadError_> yea
[01:51:59] <ReadError_> i set all that right
[01:52:05] <ReadError_> i just cant find where the offset is
[01:52:31] -!- Tom_L [Tom_L!~Tl@unaffiliated/toml/x-013812] has joined #linuxcnc
[01:53:15] <alex4nder> what I do is I home the mill, fixture the material, and then move the spindle to where I know exactly where it is in relationship to what I'm working on, and then touch off.
[01:53:19] <ReadError_> hmm actually
[01:53:25] <ReadError_> on this machine, its fine
[01:53:33] <ReadError_> i was running in vmware esxi for testing earlier
[01:53:38] <ReadError_> maybe i need to resync my configs

[03:07:26] <djdelorie> define "hand"
[03:07:31] <ReadError_> is that some kind of innuendo ?
[03:07:32] <ReadError_> hehe
[03:07:40] <ReadError_> working wood with your hand...
[03:07:46] <toastydeath> jack planes, chisels, back saws
[03:07:47] * ReadError_ has been on the internet too long
[03:07:54] <toastydeath> hand powered tools
[03:07:57] <elmo40> by hand do you mean clamp it to a vice and press Start? ;)
[03:08:13] <djdelorie> I do a little, but usually as part of a larger power-tool project
[03:09:28] <toastydeath> i am looking at buying nothing but hand tools because it's all the room i've got
[03:09:43] <ReadError_> you need a bunk bed
[03:09:46] <jdhNC> all you need is a good knife.
[03:09:48] <ReadError_> more room for activities
[03:10:26] <ScribbleJ> toastydeath, how do you plug yourself into linuxcnc? I'm confused.
[03:10:43] <toastydeath> ?
[03:10:50] <Tom_itx> heh
[03:11:17] <elmo40> ScribbleJ: no plug required. Bluetooth all the way! ;)
[03:11:42] <Tom_itx> good set of chisels and a mallet
[03:12:06] <djdelorie> and a ryoba
[03:12:07] <ScribbleJ> elmo40, if you have a bluetooth you might want to see a dentist.
[03:12:19] <ReadError_> so yall
[03:12:27] <ReadError_> i ordered a d525
[03:12:31] <ReadError_> should be here tomorrow
[03:12:43] <ReadError_> if it sucks, ill turn it into a media pc or something and get the one alex4nder has
[03:13:16] <elmo40> ReadError_: what does alex4nder have?
[03:13:17] <jdhNC> I have an intel d525
[03:13:28] <ReadError_> 4700 something i think
[03:13:32] <ReadError_> i dont have it on this pc here
[03:13:39] <ReadError_> jdhNC, does it suck?
[03:13:49] <jdhNC> nope, great. small, cheap, low latency
[03:13:56] <Tom_itx> it's a good board for linuxcnc
[03:13:57] <ReadError_> what do you get ?
[03:13:59] <Tom_itx> i have one
[03:14:08] <ReadError_> turns out, perfect timing
[03:14:17] <ReadError_> just put 16gb ddr3 in my macbook
[03:14:24] <ReadError_> so i have some dimms for it ;)
[03:14:42] <jdhNC> I only put 2gb in mine, seems fine.
[03:14:55] <Tom_itx> i filled mine, whatever it would hold
[03:14:58] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/intel_atom/atom_index.php
[03:15:14] <Tom_itx> newegg is your friend
[03:15:18] <ReadError_> i think 4gb is the limit
[03:15:25] <ReadError_> i got an amazon gift card from work
[03:15:28] <ReadError_> so i used it
[03:15:35] <ReadError_> plus, amazon prime i got overnight for 3.99
[03:15:39] <jdhNC> I bought mine with an amazon gift card from work
[03:16:12] <ReadError_> ;o
[03:16:14] <ReadError_> lol
[03:16:22] <ReadError_> what kind of latency yall getting?
[03:16:28] <ReadError_> alex4nder was getting 7k with his
[03:16:31] <ReadError_> or something super low
[03:16:40] <Tom_itx> sounds about right
[03:16:58] <jdhNC> I can get mine up higher with IO
[03:17:14] <jdhNC> but, I don't and I'm using a mesa so I don't really care.
[03:17:27] <Tom_itx> same here
[03:17:30] <jdhNC> what size wire do people use for steppers
[03:17:56] <Tom_itx> i'm not sure what i had
[03:18:22] <ReadError_> oh you get about 7k also?
[03:18:36] <Tom_itx> gawd i gotta reset my router...
[03:18:37] <jdhNC> 5k just sitting there

[04:45:22] <joe9> is an intel atom cpu the recommended cpu for linux cnc?
[04:45:38] <joe9> or, is there something better/cheaper?
[04:45:48] <Thetawaves> cheaper than an atom?
[04:45:52] <joe9> i have an amd one, but that has latency issues once in a while.
[04:46:05] <Thetawaves> yeah thats bad
[04:46:13] <joe9> and a celeron cpu that gives overruns within a few mins of starting the latency test.
[04:46:43] <joe9> i am not sure if I can. but, it would be cool if the intel atom cpu is compatible with the celeron.
[04:46:48] <joe9> will have to check.
[04:47:03] <joe9> Thetawaves: do you recommend the intel atom?
[04:47:13] <joe9> i have never used it. but, I have heard it mentioned here before.
[04:47:19] <Thetawaves> i have one, works fantastic
[04:47:32] <joe9> ok, cool. will get that. thanks for the advice.
[04:47:45] <Thetawaves> maximum latency is about 7us
[04:48:44] <Thetawaves> i have Atom 330 2x
[04:50:58] <joe9> do you remember the cpu socket?
[04:51:14] <joe9> i think atom uses socket 441
[04:51:15] <Thetawaves> no
[04:51:17] <joe9> from wiki.
[04:51:35] <joe9> for the celeron, I think the pentium uses the same socket.
[04:52:01] <joe9> will have to check if I can just get a pentium cpu, vs buying a motherboard + atom cpu.
[04:52:40] <joe9> Thetawaves: any experiences with Pentium or Pentium D cpu's?
[04:52:42] <Thetawaves> it cost me 180 for the whole computer
[04:52:52] <Thetawaves> nope
[04:57:36] <joe9> Thetawaves: oh, really. 180 is not that expensive, compared with how much the other parts of the mill cost.
[04:58:18] <Thetawaves> exactly
[04:58:38] <Thetawaves> and i got 2 gigs of ram in that machine
[04:58:42] <Thetawaves> WAY more than it needs
[05:01:06] <joe9> Thetawaves: where did you buy that pc?
[05:01:34] <joe9> Thetawaves: with the atom pc, do you ever get the message about latency while using linuxcnc?

[11:52:56] <A1Sheds> hmmm, the A/D boards by Mesa are all PC104, anyone have suggestions for A/D cards or USB dongles with EMC support?
[11:53:55] <awallin> A1Sheds: what do you want A/D for? The mesa digital IO can be used (e.g. pulse-widht, pulse-rate) if you don't need that accurate AD
[11:55:32] <A1Sheds> awallin: are there low cost A/D modules with PWM/freq output?
[11:55:52] <A1Sheds> I can build them, but I'm trying to avoid that
[11:56:05] <awallin> A1Sheds: not sure.. I looked at a current-sensing (A/D over shunt resistor) chip from IRF once..
[11:56:51] <A1Sheds> I'm using them to measure temperature and pressure on a machine
[11:57:20] <A1Sheds> 16bits would be nice
[11:57:30] <awallin> or maybe someone wrote an I2C driver for mesa/fpga ?
[11:58:13] <jthornton> doesn't skunkworks use an arduino to measre temperature on the K&T?
[11:58:16] <micges> awallin: for what devices?
[11:58:55] <awallin> micges: I was thinking you could use cheap sensor-chips with an I2C interface and hook them up to custom mesa firmware+dirver. maybe.
[11:59:03] <A1Sheds> there is some arduino support over USB
[11:59:31] <micges> awallin: interesting
[11:59:37] <A1Sheds> that might be the avenue to expand since the A/D is not real time

[12:21:03] <A1Sheds> using what SPI card?

[12:25:24] <alex_joni> A1Sheds: the only AD card I know from mesa is teh THCAD (for plasma THC)
[12:25:51] <Jymmm> !!! THC !!!
[12:26:32] <alex_joni> it should probably work even with a 5i25
[12:26:45] <A1Sheds> I'd like to expand LinuxCNC to control machines that are not tools, things like extruders and injection molding etc
[12:26:52] <alex_joni> A1Sheds: but wait for andypugh or pcw (from mesa)
[12:26:57] <jthornton> it does work with a 5i25/7i76
[12:27:10] <alex_joni> or just drop a link to the devel list, or directly to mesa
[12:27:47] <A1Sheds> he mentioned voltage to freq and using the PWM inputs
[12:28:02] <A1Sheds> but we need AD over SPI or USB
[12:28:26] <Jymmm> O_o
[12:29:13] <alex_joni> the THCAD does frequency to voltage conv.

[12:29:46] <A1Sheds> I'm trying to find it at the Mesa site
[12:30:01] <alex_joni> http://www.mesanet.com/aiodaughter.html
[12:30:03] <alex_joni> last one
[12:40:13] <A1Sheds> only 1 channel of A/D
[12:40:49] <A1Sheds> might be handy for it's intended applications
[12:41:17] <A1Sheds> I'd need 8 -16 for an extruder
[12:42:19] <A1Sheds> there might be 6-8 heat zones in a barrel
[12:43:28] <A1Sheds> i have to check on the SPI drivers
[12:44:11] <A1Sheds> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?SPI_Sub-Driver_For_Hostmot2
[12:58:11] <jthornton> the 1" x 24" long extruder's I had only had 2 zones on the barrel and a few more down the piping, might have been better with 3 zones
[12:59:55] <jthornton> would have been much better if I knew about drying hoppers back then...
[13:00:11] <A1Sheds> moisture issues?
[13:00:38] <A1Sheds> I saw a video of somebody trying to extrude a very wet resin
[13:00:57] <A1Sheds> came out of the nozzle like foam

[13:14:58] <Jymmm> evena kid could do it!
[13:15:05] <Jymmm> ages 3+
[13:15:35] <A1Sheds> yeah, that's it, only more expensive
[13:15:54] <A1Sheds> nothing gets past you Jymmm :)
[13:16:05] <Jymmm> if ya paid more than $12, you got ripped off
[13:16:47] <A1Sheds> I wish that all products came with info in 12 languages
[13:16:56] <Jymmm> A1Sheds: you have both extruder and mold injection?
[13:17:12] <A1Sheds> Jymmm: we build custom machines
[13:17:25] <A1Sheds> lab protos etc
[13:17:43] <Jymmm> so not operate them or make dies?
[13:17:58] <A1Sheds> we can make dies
[13:18:26] <A1Sheds> we only run them to test either the new type of machine or the new type of plastic
[13:18:32] <Jymmm> thermoset or aluminum extrustion
[13:19:08] <A1Sheds> either + thermoplastics and elastomers
[13:19:38] <A1Sheds> we mostly work on new materials
[13:20:31] <Jymmm> what is the biggest bitch with a dies profile?
[13:20:44] <Jymmm> thick walls?
[13:21:21] <A1Sheds> bad designs
[13:21:35] <Jymmm> but what makes it a bad design?
[13:22:08] <A1Sheds> mostly thin walls over too long a distance
[13:22:32] <A1Sheds> you can machine about anything but will it actually work in production
[13:22:39] <Jymmm> and what does that do?
[13:22:43] <JT-Shop> A1Sheds: yea mosture issues with the plastic as we only had 110% humidity in New Orleans all the time almost
[13:23:22] <JT-Shop> cold cut was the worst as it was talc filled and would suck up the water
[13:34:53] <A1Sheds> http://www.youtube.com/watch?v=wE_KTLlrdMA&feature=related @1:10 you can see a typical old school control panel with 10 heat controllers
[13:36:40] <JT-Shop> this is similar to what we had http://www.youtube.com/watch?v=xtyHFKE_Y2k
[13:37:46] <JT-Shop> but ours were of a much simpler design
[13:38:19] <A1Sheds> never saw a feed rate in NPM (nails per minute)
[13:39:02] <JT-Shop> this is the whole process http://www.youtube.com/watch?v=CUTTmtLKD2g
[13:40:02] <JT-Shop> we had a whole row of the purple machines that made nails
[13:40:10] <A1Sheds> so they arent forged :)

[13:41:59] <A1Sheds> what dia tube?
[13:42:04] <Jymmm> 1/2"
[13:42:30] <A1Sheds> sealed like a polybag?
[13:42:50] <Jymmm> Like a toothpaste tube (crimp) maybe.
[13:43:01] <Jymmm> maybe no crimp if it's a pita
[13:43:23] <Jymmm> and maybe two sheets of paper thin walls =)
[13:43:26] <A1Sheds> http://www.youtube.com/watch?v=AHTcEq6_W74

[13:44:21] <A1Sheds> few mills
[13:44:53] <Jymmm> .7mm wall thickness (about)
[13:45:00] <A1Sheds> what rate? tubes per minute etc

[13:46:20] -!- JT-Shop has quit [Quit: Leaving]
[13:47:16] <A1Sheds> more power for that thickness

[13:48:24] <A1Sheds> sounds good

[13:54:34] <Jymmm> Timer 1-8 seconds
[13:55:07] <A1Sheds> and 8 seconds wasn't long enough? if so then it just wasn't getting hot enough

[14:09:05] <A1Sheds> Jymmm: how did the laser cutter air filter work out?
[14:09:16] <Jymmm> Got razor blade, but I'm wondering why none of them are the "clear" silicon
[14:09:27] <A1Sheds> or mold it yourself
[14:10:09] <A1Sheds> laser cut a strip out of some sheet as a mold
[14:11:55] <Jymmm> the air scrubber? Initially I want the blower IN the same enclosure, but that didn't work out as the desinty of the pellets was too much. I've since pulled the blower out and haven't had a chance to redesign the innerards to accomidate the less denstiy of pellets into thinner layers.
[14:12:43] <Jymmm> you would never think pellets could affect airflow as much as they did

[14:14:42] <Jymmm> MY issue is I designed it for one thing, and having to dramatically make changes to have thinner layers

[15:45:07] <ctjctj> cradek: I can make the spindle perpendicular to the table. I've got enough adjustment for tilting the spindle. It is making the XY cutting plane parallel to the table. So it looks like I'll need to adjust the table some way. So much fun.

[15:51:34] <archivist> not a bad thing, as it makes it accurate
[15:52:39] <ctjctj> I have shitty power to the garage where cnc is. Which means that cutting pine is not much of a problem but cutting the MDF requires me to stand there with the dust collector for an hour or two while things cut. (Power means that I can't trust the drivers)

[16:34:21] <Connor> What is a good diameter for a fly cutter?
[16:34:55] <roycroft> big enough to do the work you need to do and small enough that your mill can handle it :)
[16:35:27] <Connor> Well.. I guess the question is.. what's the best fit for my mill then.. :)
[16:38:38] <andypugh> What sort of mill/
[16:38:40] <andypugh> ?
[16:38:47] <Connor> G0704
[16:39:19] <Connor> I think BF20 style/size over the pond..
[16:39:23] <andypugh> plastic gears?
[16:39:44] <Connor> I think it does have some yes... I plan to upgrade to belt drive at some point.
[16:40:02] <andypugh> Well, if you get a flycutter you will be upgrading sooner than you think.
[16:40:16] <Connor> Eh?
[16:40:27] <roycroft> i don't use fly cutters, personally
[16:40:47] <roycroft> i have a 3" carbide insert face cutter on my x3 and it works fine
[16:41:05] <roycroft> i don't go hogging 0.050" at at time with it
[16:41:08] <roycroft> at a
[16:41:12] <andypugh> flycutters cut very intermittently, and bang the same tooth every rev. Then it falls off.
[16:41:45] <roycroft> if you have a small mill you need to keep your feeds and speeds correct, but take light cuts
[16:41:45] <andypugh> Using a flycutter is why mine now has metal gears in the head.
[16:41:52] <djdelorie> I own a fly cutter. For my lathe. I'm not sure what the point is.
[16:42:10] <andypugh> And if I had known then what I know now, I wouldn't have done that either, as it is far too loud for comfort.
[16:42:53] <andypugh> It does depend how many flies you want to cut, and how big they are. Mosquitos are probably OK on a Mini-Mill, bluebottles probably not :-)
[16:43:47] <roycroft> bug zappers are more fun
[16:43:58] <roycroft> they're only noisy for a brief moment, when you know the thing is working
[16:44:08] <roycroft> you need good ventilation with a bug zapper, though
[16:45:04] <Connor> Mosquitos, bluebottles ??
[16:45:44] <andypugh> I was being whimsical, sorry.
[16:46:52] <andypugh> If your mill has plastic gears in the head, then I wouldn't use a flycutter. I did, and it broke.
[16:47:08] <andypugh> If the main gears in the head are metal, then it's probably fine.
[16:48:09] <andypugh> It does look like yours is a bigger, better machine than mine, so it might not apply.
[16:48:35] <Connor> Does it matter what your cutting with your statement? I primarily cut aluminum.
[16:49:29] <andypugh> Not really, the problem is that the gears unload while the cutter is cutting air, then bang together when the cutting tip enters the work.
[16:49:52] <andypugh> It's no problem at all with a vee-belt drive.
[16:57:18] <archivist> if the cut is light enough any mill should handle it
[16:57:37] <archivist> with the emphasis on light cut
[16:58:48] <roycroft> which is what i've been saying
[16:58:51] <archivist> and be careful about balance
[16:59:21] <roycroft> the only caveat being if it's a really large fly cutter you need to know if your mill can turn slowly enough to get the right speed
[16:59:55] <roycroft> if your lowest speed is 200rpm you might have trouble with a big fly cutter

[17:26:02] <cradek> I used a dual PIII-1000 for a long time
[17:26:17] <cradek> I replaced it with a P4 which seems no faster
[17:27:53] <joe9> cradek: is PIII better than a celeron for latency purposes? I tried a celeron and it has latency spikes once a minute or so.
[17:28:10] <joe9> the celeron is not good enough for linuxcnc, atleast the one that I had.
[17:28:23] <cradek> celerons aren't good enough for anything

[17:37:14] <joe9> i am trying with a PIII http://codepad.org/vGNJKrvG now. let me see how it works.
[17:37:23] <joe9> an old machine that I had lying around.
[17:37:39] <Loetmichel> my new CPU for linuxCNC is a c2d ;-)
[17:37:49] <joe9> what is a "c2d"?
[17:37:54] <Loetmichel> core 2 duo
[17:38:01] <Loetmichel> 2.8 or 3ghz
[17:38:09] <Loetmichel> (dont remember)
[17:38:34] <joe9> i noticed that the cpu speed does not seem to be the issue. the issue seems mostly to do with some power management features or bad drivers.
[17:38:46] <joe9> or something else.
[17:38:49] <Loetmichel> joe9: more or less right
[17:39:16] <Loetmichel> but the cpu has to have a minimum power ;-)
[17:39:17] <joe9> i am hoping that with a PIII, I avoid the corner cases faced by the celeron and Amd.
[17:39:40] <Loetmichel> hmmm
[17:39:56] <Loetmichel> the new machine i am building for a co-worker has a p4 inside
[17:40:05] <Loetmichel> 3ghz
[17:40:31] <Loetmichel> but there is the non-existent-3d-power of the onboard graphics chip the issue i think
[17:42:00] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=13089&g2_imageViewsIndex=1 <- sufficient, but could be better ;-)
[17:43:24] <joe9> Loetmichel: how much did the p4 cost? I might just use the p4 with the celeron socket.
[17:43:38] <Loetmichel> joe9: 0.0
[17:43:45] <Loetmichel> got it from the company
[17:43:51] <joe9> the socket seems to be the same for both.

[18:15:38] <IchGuckLive> andypugh: my 26 IBM A50 did manage to get below 10000 with that
[18:15:54] <ReadError_> IchGuckLive: I found one for EMC2
[18:16:07] <IchGuckLive> use Fanuc F11
[18:16:26] <IchGuckLive> this will give you a very good resault
[18:17:00] <IchGuckLive> in freemill its the 11m
[18:17:20] <ReadError_> i cant see where in the gcode its going down below the work surface
[18:17:22] <ReadError_> very strange
[18:17:55] <ReadError_> hmm that does it correctly actually
[18:18:03] <ReadError_> but its missing my drill routine
[18:18:03] <IchGuckLive> did you set the zero to the negativ from the part block
[18:18:26] <andypugh> IchGuckLive: You would need a bigger mill.
[18:19:13] <IchGuckLive> the mill is actuly 5m in x 2m in y and 1,5m in z with a 0.3 acuracy
[18:19:37] <ReadError_> VisualMill is very nice otherwise..
[18:19:56] <IchGuckLive> foam negatices or positives with 200 stepwidth
[18:21:16] <IchGuckLive> ReadError_: on that why arend you using heekscad for this it also gets here some good resaults
[18:21:51] <IchGuckLive> ReadError_: i expect the part showing is the reaseon
[18:22:18] <IchGuckLive> joe9: hows it going on opencascade
[18:22:28] <andypugh> Yes, and Mt Rushmore is 18m in Z, 30m in x….

[18:24:40] <ktchk> Hi did anyone built heekscnc under ubuntu 12.04 lts?
[18:24:48] <IchGuckLive> mount Rushmore i think is in the standart of heekscad includet
[18:24:51] <A1Sheds> is thee a new framework?
[18:25:10] <A1Sheds> or should we stick with USB+arduino for now?
[18:25:11] <IchGuckLive> i made also more stl for US national points
[18:26:04] <andypugh> A1Sheds: That was an unworkable idea, when I tried to copy it, so I did it all a very different way.
[18:26:05] <ReadError_> IchGuckLive: using that processor, its drilling my holes backwards
[18:26:20] <ReadError_> its going up instead of down lol

[18:36:21] <IchGuckLive> i see first why is the part offset not Zero in the middel of the big hole ?

[18:47:39] <IchGuckLive> yes
[18:47:53] <IchGuckLive> the Z offset is the H 2 is the linenumber
[18:48:03] <IchGuckLive> you can combinate that with all

[22:39:02] <andypugh> 8500 is less than 10600 in the maths I learned at school.
[22:39:33] <r00t4rd3d> 2gig of 10600 14.99 2g of 8500 , 19.99
[22:39:52] <andypugh> I only have 1 gig, that's plenty for LinuxCNC

[22:47:05] <r00t4rd3d> that should work in the 525mw right?
[22:48:08] <alex4nder> it will work

[22:57:30] <robin_sz> I trust you all are well and enjoying a fine evening
[22:58:02] <robin_sz> could I enquire what you fine gentlemen would suggest as a free PCB layout tool?
[22:58:14] <robin_sz> my board is too big for the free version of Eagle :(
[22:58:30] <Tom_itx> i'm partial to eagle but i'm beyond the free part
[22:58:35] <Tom_itx> geda maybe?
[22:58:39] <Tom_itx> i've never used it
[22:58:42] <r00t4rd3d> the pirate bay
[22:58:54] <robin_sz> err, not PB
[22:59:05] <djdelorie> geda/pcb is what I use
[22:59:12] <djdelorie> but I'm biased :-)
[22:59:18] <robin_sz> ive heard of one guy coming unstuck with a dodgy eagle license
[22:59:31] <robin_sz> the board house he sent the files to reported him
[22:59:34] <Tom_itx> i paid for one
[22:59:35] <r00t4rd3d> they dont have a listing anyways
[22:59:47] <robin_sz> geda
[22:59:55] <robin_sz> does it have schematic capture too?

[23:01:11] <Tom_itx> i'm not worried about it anyway
[23:01:22] <robin_sz> well, yeah. I prefer not to use dodgy licenses
[23:01:31] <robin_sz> buy one or use gpl, easy
[23:01:35] <Tom_itx> i don't send the board files anywhere
[23:01:38] <djdelorie> robin_sz: start here: http://www.delorie.com/pcb/docs/gs/
[23:01:52] <Tom_itx> your board goes beyond the free license?
[23:02:01] <Tom_itx> you could get a student license
[23:02:02] <djdelorie> although there's a one-click import function in pcb now, instead of gsch2pcb
[23:02:07] <Tom_itx> or not for profit...
[23:02:23] <robin_sz> truesells
[23:02:28] <andypugh> djdelorie: Ah, that sounds good, and only 10 years after it became an obvious thing to do.
[23:02:33] <Tom_itx> since element 14 bought them i don't know their pricing structure anymore
[23:02:47] <robin_sz> let me go and look if geda sucks or is lovely
[23:02:55] <djdelorie> a lot of things are obvious after the fact ;-)
[23:03:06] <alex4nder> heh
[23:03:10] <alex4nder> yah, that's pretty innovative
[23:04:03] <andypugh> I am moving to gEDA on my Mac. I was happy enough with DesignSpark, but prefer to run native.
[23:04:33] <djdelorie> there's a #geda on OFTC that I hang out on, if anyone needs real-time help with it
[23:04:45] <roycroft> i'm starting to use geda
[23:04:48] <roycroft> it seems quite capable
[23:05:51] <robin_sz> Tom_itx, its 965 eur, too much for me
[23:06:12] <robin_sz> i need more than 100 x 160
[23:06:16] <roycroft> it's not very well-behaved on os x, though
[23:06:24] <r00t4rd3d> robin_sz, #arduino might be able to point you in the right direction also
[23:06:27] <Tom_itx> ok
[23:06:58] <robin_sz> Tom_itx, the hobbyist would be fine, apart from the 100 x 160 limit, which sucks ass
[23:07:07] <andypugh> Under Windows, DesignSpark is pretty good, and is free from RS. (as in, they have promised it will always be free). I think Farnell bought Eagle. (OK, Internet rumour, no checking)
[23:07:54] <Tom_itx> robin_sz, yeah i don't worry with that on mine
[23:08:24] <djdelorie> the first eagle component I used had the wrong pin spacing. It was a db25 connector too :-P
[23:08:53] <andypugh> I had hoped that DesignSpark would interface nicely with RS parts catalogues, but it really doesn't. Which seems like a missed opportunity. It would be immensely nice for the RS part number to bring up schematic and layout.
[23:09:12] <robin_sz> is designspark free?
[23:09:15] <Tom_itx> i started using eagle about ver 2.xx and just kept going
[23:09:20] <andypugh> You do at least know where you are with gEDA
[23:09:36] * robin_sz places a capacitor on the schematic
[23:09:47] <robin_sz> so far so good
[23:10:15] <Tom_itx> andypugh can you edit packages of symbols with it if you find out you have the wrong package?
[23:10:16] <robin_sz> I take it that geda back annotates between the pcb and the schematic?
[23:10:26] <Tom_itx> i would hope so
[23:10:30] <Tom_itx> that's basic
[23:10:34] <djdelorie> there's a netlister that extracts all the information from the schematics that the pcb layout tool needs
[23:10:40] <djdelorie> File->Import runs it :-)
[23:11:01] <andypugh> robin_sz: Yes, it's free. But not Free. Tom_itx Yes, you can. http://www.designspark.com/pcb
[23:11:03] <djdelorie> there's no *back* annotation yet, just *forward* annotation
[23:11:14] <robin_sz> but a netlist wont tell it what the package is will it?
[23:11:15] -!- pfred1 [pfred1!~pfred1@unaffiliated/pfred1] has joined #linuxcnc
[23:11:16] <andypugh> But please note that I am using gEDA now.
[23:11:29] <djdelorie> so all connectivity and attribute changes need to be done in the schematic tool, then imported.
[23:11:36] <robin_sz> ok
[23:11:54] <pfred1> I've thought about using gEDA
[23:11:59] <djdelorie> yes, the netlister includes the package. It's the footprint= attribute on the schematic symbol. Go read the tutorial I linked to ;-)
[23:12:07] <robin_sz> okies
[23:12:51] <Tom_itx> sounds like you have plenty of help here with it
[23:12:51] <andypugh> As far as I can see, with all of them, you need to create a schamatic and a layout for almost any compoment, as they never have the one you just bought in the library. And it is a complete pain in the neck with all of them.
[23:12:57] <djdelorie> the corresponding gschem tutorial is at http://wiki.geda-project.org/geda:gsch2pcb_tutorial but only read up to "Generate PCB files..."
[23:13:03] <robin_sz> i was just sort of surprised it let me pick a capacitor to put on the scmeatic without being offered a choice of footrpints

[23:13:18] <Tom_itx> andypugh yeah, i have a growing library
[23:13:18] <djdelorie> robin_sz: you get to choose the footprints later :-)
[23:13:22] <robin_sz> andypugh, eagle does at least have all the relevant SMD packagaes for most things
[23:13:31] <Tom_itx> although eagle is much better with it's libs lately
[23:13:36] <robin_sz> in only do smd
[23:13:48] <pfred1> I always end up having to make some part
[23:13:48] <djdelorie> andypugh: we've been building web-based package designers, like http://www.gedasymbols.org/user/dj_delorie/tools/dilpad.html
[23:14:00] <robin_sz> neat
[23:14:13] <robin_sz> lets hope they have one for an ECC83 ;)
[23:14:17] <Tom_itx> robin_sz, eagle also added that refpackages.lbr with lots of layouts
[23:14:26] <robin_sz> yeay
[23:14:30] <andypugh> I found making new parts in Eagle really frustrating. DesignSpark is a bit better, but still not exactly smooth. gEDA os just, well, Linuxy. There are two ways to do it, and a battleground about which is best.
[23:14:46] <pfred1> andypugh you and me both I always sweat out making parts
[23:14:48] <djdelorie> the geda list has had quite a few philosophical discussions on how to "best" manage libraries
[23:14:49] <robin_sz> and I use the designspark eagle library a lot :)
[23:14:50] <Tom_itx> i don't think any are seamless
[23:15:02] <djdelorie> andypugh: way more than just two :-)
[23:15:03] <robin_sz> oh did I mean sparkfun library

[23:33:41] <Tom_itx> there are chickens running wild on Gran Caymen now after the hurricane went thru there. they can't catch them all
[23:33:53] <djdelorie> the logic is: an egg and the adult it grows into have the same DNA, therefor must be the same species. However, an adult and the egg it lays need not be, so the change from "not a chicken" to "chicken" must have happened when the egg was made
