#emc | Logs for 2006-03-16

[01:28:21] <jepler> # For this configuration, OUTPUT_SCALE is not used, because
[01:28:22] <jepler> # EMC always overwrites it on shutdown
[01:28:25] <jepler> Is that true anymore?
[01:28:49] <jepler> (I mean, does emc overwrite OUTPUT_SCALE on shutdown)
[01:28:51] <jepler> (emc2)
[01:29:04] <giacus> jepler: for waht I seen is true
[01:29:06] <cradek> no
[01:29:13] <giacus> no ?
[01:29:21] <cradek> emc2 doesn't rewrite the ini anymore, hasn't for a while
[01:30:00] <cradek> if OUTPUT_SCALE isn't used anymore, we should hurry and take it out of all the inis
[01:30:33] <jepler> which xxx_SCALE is the number of encoder counts per inch(mm)?
[01:30:40] <cradek> INPUT
[01:30:47] <jepler> and OUTPUT_SCALE is what, for servos?
[01:31:04] <cradek> uh, I guess I don't know
[01:31:29] <cradek> # number of encoder ticks / unit
[01:31:29] <cradek> INPUT_SCALE = 200 0
[01:31:29] <cradek> # dac gain for output
[01:31:29] <cradek> OUTPUT_SCALE = 1.000 0.000
[01:31:40] <cradek> (stg.ini)
[01:32:29] <jepler> for univpwn:
[01:32:30] <jepler> # Scaling: The PWM_OUTPUT_SCALE should be the speed
[01:32:30] <jepler> # in UNITS/second (inches/sec or mm/sec) that would be
[01:32:30] <jepler> # reached if the PWM duty cycle was 100%.
[01:33:02] <cradek> how are you supposed to know that?
[01:33:29] <jepler> good question
[01:38:51] <SWPadnos> those scale values have always been somewhat hardware-dependent (in terms of their meaning)
[01:42:22] <cradek> I guess you could hook it up for a second and measure the travel...?
[01:50:03] <SWPadnos> you mean to determine the output scale? (on a univpwm board)
[01:52:29] <giacus> guys, I tried time ago a rudimental driver with emc2 pseudo-pwm, must I say was very disappointed, very slow and poor
[01:52:59] <giacus> I dont in any possible good results from there ..
[01:53:46] <giacus> a microcontroller driver based should be nice
[01:54:06] <giacus> if jepler can get it running , he's a genius
[01:54:22] <giacus> good luck :D
[01:56:07] <Jymmm> Didn't someone here say they had some engravings tooling? Anyone remember what the tip and angle was?
[01:57:03] <cradek> I've done very small engraving with my carbide pcb tools that come to a 60� point
[01:57:55] <Jymmm> do you know what the flat tip width would be on those?
[01:58:13] <cradek> what is flat tip width?
[01:58:43] <Jymmm> the tip is flat across; wodths beign from .01 to .06
[01:58:56] <Jymmm> widths being
[01:59:06] <cradek> I can cut .008 separations on pcbs with them
[01:59:26] <cradek> they're pretty pointy
[01:59:30] <Jymmm> are these the ones that look like rasp files?
[01:59:52] <cradek> no, they look like a perverse pointy drill bit
[02:00:08] <Jymmm> ah, ok.
[02:00:54] <giacus> jepler: here's what I like, but I never tried it.. http://www.jrkerr.com/icproducts.html
[02:01:04] <giacus> you probably already know it
[02:01:05] <Jymmm> I'm ordering some tooling, and thought I'd toss in an engraving tool as well. They offer .005 .01 .02 .03 .04 .05 .06 tip widths in both 30 and 60 degree angles
[02:01:19] <giacus> routines used should be free too
[02:02:43] <giacus> the software section of that website have some interesting file
[02:09:34] <giacus> * giacus is fighting with css sheets style :(
[02:27:29] <jepler> yay, next step of motor spinning complete: emc varies the stepper's speed depending on the freqgen input
[02:27:36] <jepler> unfortunately, freqgen doesn't output more than a 50% duty cycle
[02:27:48] <cradek> yay
[02:29:13] <jepler> the documentation says it should work that way (give >50% duty cycle) but it doesn't seem to
[02:29:49] <cradek> wonder if I have the email about jmk's robot
[02:32:06] <cradek> yes, but he doesn't say much about the hal configuration
[02:35:11] <giacus> jepler: just curious, how much is amplitude you get there ? tried with a scope ?
[02:35:42] <jepler> giacus: I'm looking at the freqgen.0.up output in halscope
[02:36:06] <jepler> giacus: I can see that I get at most a 50% duty cycle (TRUE one base-period, FALSE the next)
[02:36:50] <giacus> I tried with an external scope too, time ago, it was very low for me
[02:39:10] <jepler> however, I'm not measuring the amplitude of anything
[02:39:28] <SWPadnos> it is a step generator, so the 50% duty cycle is expected
[02:39:44] <SWPadnos> if you have a bunch of high periods, it's still only one step
[02:40:46] <giacus> for the test I did with an L293(if I remember well) the torque was near to zero :(
[02:40:49] <jepler> Step type 1 has two outputs, up and down. Pulses appear on one or the other, depending on the direction of travel. Each pulse is one thread period long. If you need a distinct pulse for each step, the frequency needs to be limited to half of the thread rate, to allow for one low period between pulses
[02:40:54] <jepler> However, freqgen allows higher frequencies, up to the thread rate. This allows step type 1 to be used as a pseudo-PWM source, or filtered to use as a D-to-A converter. At the maximum frequency (equal to the thread rate), the up or down output will remain on constantly.
[02:40:58] <jepler> -- hal introduction pdf
[02:42:12] <SWPadnos> ... A filter
[02:42:13] <SWPadnos> and differential amp connected between UP and DOWN can
[02:42:15] <SWPadnos> produce a +/-10V signal, with bandwidth and resolution
[02:42:17] <SWPadnos> determined by the filter (in general, faster bandwidth
[02:42:18] <SWPadnos> gives lower resolution, and vice-versa.) ...
[02:42:20] <SWPadnos> -- freqgen.c
[02:43:13] <giacus> SWPadnos: infact..
[02:43:26] <SWPadnos> though it dfl
[02:43:51] <giacus> whan I tried without filter or amp it was around +/- 1 V
[02:43:52] <SWPadnos> though it does look like stepping_type=1 should do pseudo-PWM, as you expect
[02:45:36] <SWPadnos> are you driving freqgen "manually", or with emc?
[02:46:50] <jepler> I'm starting emc as a way to get all the realtime to work, but right now I'm just doing
[02:47:05] <jepler> 'sets X-vel 5e3' and the like
[02:47:46] <SWPadnos> ok, and the freqgen isn't connected to anything else
[02:47:59] <SWPadnos> err - X-vel isn't connected
[02:52:51] <jepler> right
[02:53:00] <jepler> I think it's simply a bug in freqgen
[02:53:26] <SWPadnos> it could be. I'm looking at the update_freq function now
[02:54:21] <jepler> I made a change and now I can get more than 50% HIGH output
[02:54:33] <SWPadnos> actually, I think the bug is there. there's no special case for the freq limit for type 1
[02:54:44] <jepler> yeah that's basically what I saw
[02:56:20] <CIA-8> 03jepler * 10emc2/src/hal/components/freqgen.c:
[02:56:20] <CIA-8> bugfix: in step_type 1, frequency is 2 times the maxf, since it's permitted for the output signals to be high in successive periods
[02:56:20] <CIA-8> feature: add COUNT output; it directly exports the item show in the hal introduction.pdf as "COUNT".
[02:58:11] <SWPadnos> does that duplicate rawcounts?
[02:59:04] <SWPadnos> nevermind
[02:59:24] <giacus> night
[03:09:46] <SWPadnos> night, all
[03:09:52] <SWPadnos> SWPadnos is now known as SWP_Away
[04:52:15] <A-L-P-H-A> Who's got a lathe able to handle 6.5" dia? I may have a short production run, if the price is right. :) Need to bore a hole ~2", and drill 2 sets of holes. material 6061.
[04:52:42] <Jymmm> A-L-P-H-A: I can do that.... tolernace +- 24"
[04:52:43] <A-L-P-H-A> ~1.5" thick discs of alu 6061.
[04:52:55] <A-L-P-H-A> Jymmm. 2' eh? :) I'll keep you in mind.
[04:53:02] <Jymmm> A-L-P-H-A =)
[04:53:17] <A-L-P-H-A> Short meaning like 20 units.
[04:53:38] <fenn> whatcha makin?
[04:53:44] <A-L-P-H-A> wheel adapters.
[04:53:50] <fenn> for cars?
[04:53:55] <A-L-P-H-A> 4x100 to 5x113.
[04:53:58] <A-L-P-H-A> fenn, yup
[04:54:01] <fenn> hmm no thanks
[04:54:04] <fenn> rather not get sued
[04:54:16] <A-L-P-H-A> 'not for street use'
[04:54:18] <A-L-P-H-A> :)
[04:55:28] <SWP_Away> A-L-P-H-A, I probably have a friend who can do it
[04:55:40] <A-L-P-H-A> SWP_Away, cool.
[04:55:52] <SWP_Away> that's 6.5" diameter?
[04:55:56] <SWP_Away> small stuff ;)
[04:56:07] <SWP_Away> what kind of tolerance?
[04:56:11] <A-L-P-H-A> 6.5" diameter OD... ~2" id.
[04:56:35] <SWP_Away> no problem. can it be manual, or does it need to be a CNC lathe?
[04:56:45] <A-L-P-H-A> SWP_Away, +1 mm is okay. Holes need to be equally spaced, and equidistant.
[04:57:01] <fenn> sounds more like a job for a milling machine
[04:57:10] <SWP_Away> well, he's got a CNC Bridgeport as well, so it may not need to be a lathe
[04:57:13] <A-L-P-H-A> fenn, the drilling yes. the disc, no.
[04:57:24] <SWP_Away> we've also got boring heads for the milling machine
[04:57:31] <A-L-P-H-A> SWP_Away, okay, that works.
[04:57:37] <SWP_Away> SWP_Away is now known as SWPadnos
[04:57:45] <A-L-P-H-A> I forgot about boring heads, even though I have one. :)
[04:57:48] <A-L-P-H-A> I love my lathe too much.
[04:58:10] <SWPadnos> the OD can be turned, and a locator hole put in the center. then do the bolt pattern on the mill
[04:58:22] <A-L-P-H-A> SWPadnos, yup.
[04:58:42] <fenn> * fenn hates tapping with a vengeance
[04:58:44] <SWPadnos> are you starting with a single cylinder, or with thin blanks?
[04:58:58] <SWPadnos> that's what the range of tapmatics are for ;)
[04:58:58] <fenn> 1.5" isn't really thin
[04:59:06] <SWPadnos> it's thinner than 10"
[04:59:33] <A-L-P-H-A> SWPadnos, 1.5" thick cut bars.
[04:59:43] <A-L-P-H-A> so that's why I was saying a lathe... so they could be faced.
[05:00:19] <SWPadnos> ok. does that leave enough room for turning the surface?
[05:00:25] <SWPadnos> (or surfaces)
[05:00:32] <A-L-P-H-A> can I start dealing in mm instead?
[05:00:43] <A-L-P-H-A> the total thickness is 35mm.
[05:01:04] <SWPadnos> heh - sure ;)
[05:01:16] <A-L-P-H-A> fuck it. I'll post the damn jpg of the thing. give me a sec
[05:01:22] <SWPadnos> ok
[05:02:58] <SWPadnos> that's a 165 mm OD?
[05:03:50] <A-L-P-H-A> http://lloydleung.com/gallery/wheel_adapters.png
[05:04:04] <A-L-P-H-A> don't yell at me, I didn't draw it.
[05:04:11] <SWPadnos> will that be around for a day or two?
[05:04:15] <A-L-P-H-A> yeah.
[05:04:18] <A-L-P-H-A> it'll be kicking around.
[05:04:33] <A-L-P-H-A> the outter set of holes is to be M12 (don't know what pitch yet)
[05:04:50] <SWPadnos> ok. I'll send an email with a link to that to my friend, and he'll probably get back to me tomorrow
[05:05:00] <SWPadnos> standard thread though, right?
[05:05:57] <fenn> * fenn squints at the picture
[05:06:17] <fenn> what's the radius of the bolt hole circles?
[05:06:35] <SWPadnos> 100 and 130 mm bolt hole diameter
[05:06:36] <A-L-P-H-A> fenn, it's draw not exactly right.
[05:06:52] <A-L-P-H-A> radio 50, 165
[05:06:55] <A-L-P-H-A> radius
[05:06:59] <SWPadnos> radii
[05:07:28] <A-L-P-H-A> the outter holes, again. at M12 threaded holes. not 12.00mm holes
[05:07:43] <A-L-P-H-A> I'm going to need like 20 units of them.
[05:07:51] <fenn> oh /me dumb it's on there
[05:08:05] <SWPadnos> and the inner holes are just a shoulder hole for a bolt to go through?
[05:09:45] <A-L-P-H-A> refresh that drawing. I change that top right dimension.
[05:09:51] <A-L-P-H-A> SWPadnos. yes.
[05:09:53] <SWPadnos> nice ;)
[05:10:15] <SWPadnos> and do both faces need to be mirror smooth?
[05:10:19] <A-L-P-H-A> the edges could be bevelled, but not necessary.
[05:10:38] <A-L-P-H-A> SWPadnos, not mirror. Mirror would be nice, easier to sell to people with the BLING factor that will NEVER show.
[05:10:58] <A-L-P-H-A> people are dumb... people like shiney things.
[05:10:58] <SWPadnos> ok, and it's the bolt circles and the thickness that are somewhat critical, but not the OD
[05:11:14] <A-L-P-H-A> OD is not. ID can be 57... max like 58.
[05:11:40] <A-L-P-H-A> the bolt holes are critical... but common, they're tiny holes, which shoudl be able to be done with easy. The location of them are also critical.
[05:12:10] <SWPadnos> it looks like the main issue would be the 4 holes vs 5 holes thing, and making sure that there's enough metal in between
[05:12:21] <A-L-P-H-A> overall thickness needs to be around that size. Doesn't have to be perfect... but they should all be similar if stacked next to each other on a flat surface.
[05:12:53] <SWPadnos> sure. his lathe isn't CNC, but it's "big iron", and nice and smooth
[05:13:00] <A-L-P-H-A> looks like there's like 3mm of material or so between them. Plus all the bulk around it... should be enough, but I'm no engineer.
[05:13:42] <SWPadnos> is the ridge around the center bore on the smae side as the shoulders on the inner bolt circle?
[05:14:13] <A-L-P-H-A> SWPadnos, it's a protruding shoulder.
[05:14:19] <A-L-P-H-A> look on teh bottom pic.
[05:14:25] <SWPadnos> ok - I see it in the lower drawing now
[05:14:34] <A-L-P-H-A> I have pictures too. hang on.
[05:14:44] <fenn> power cross feed looks a lot like CNC machining to the uneducated
[05:15:20] <fenn> or to the educated for that matter
[05:15:24] <SWPadnos> I have a power feed ;)
[05:15:35] <fenn> i feed my chickens the old fashioned way
[05:15:39] <A-L-P-H-A> I have a stepper motor on 3 axis on my mill. :D
[05:15:40] <SWPadnos> but I took it off when I put in vallscrews
[05:15:51] <SWPadnos> ballscrews, too
[05:15:53] <A-L-P-H-A> I would do this, but I can't handle that size on my lathe.
[05:16:00] <A-L-P-H-A> I did too!
[05:16:08] <fenn> SWP so what are you waiting for again?
[05:16:10] <A-L-P-H-A> except my mill hasn't been turned on in over a year I think.
[05:16:27] <SWPadnos> err - nothing
[05:16:35] <fenn> ah yes.. i know that situation well
[05:17:15] <SWPadnos> actually, I need to accurately measure the bearing brackets for X and Y, then design a space saver mount (like the one atElrod Machine), then go mill them
[05:17:15] <A-L-P-H-A> SWPadnos, ask you buddy for a quote for like 12 and 20 units. I can do it via me supplying materials, or not.
[05:17:43] <A-L-P-H-A> http://lloydleung.com/gallery/1.bmp
[05:17:45] <SWPadnos> ok. Aluminum is a bit pricey these days, but I suspect the shipping might make up the difference
[05:17:56] <A-L-P-H-A> SWPadnos, yup. I know.
[05:18:12] <A-L-P-H-A> SWPadnos, perferrably I would do these locally, and inspect them on sight before taking them.
[05:18:15] <fenn> heh what is that? a scale model?
[05:18:18] <SWPadnos> ok. looks easy enough ;)
[05:18:25] <SWPadnos> hell, I could do that
[05:18:28] <A-L-P-H-A> fenn, it's from the guy that wants them done.
[05:18:29] <Jymmm> Jymmm is now known as Red70sShow
[05:18:30] <Red70sShow> Red70sShow is now known as Jymmm
[05:18:32] <SWPadnos> (if I had a lathe)
[05:18:45] <fenn> if i only had a lathe..
[05:18:52] <A-L-P-H-A> I have a lathe, but I can only handle 6". not 6.5", the swing isn't big enough.
[05:18:56] <fenn> what are the rest of the words to that song?
[05:19:23] <SWPadnos> the scarecrow song?
[05:19:31] <SWPadnos> if I only hada brain...
[05:19:43] <A-L-P-H-A> maybe I'll spend the cash, and buy a cheap 8x20 lathe.
[05:19:48] <SWPadnos> heh
[05:20:03] <SWPadnos> I think my friend's is 16x40, but I'm not sure
[05:20:05] <fenn> i dunno why big lathes are so long
[05:20:13] <fenn> seems like most big stuff is short and boxy
[05:20:14] <SWPadnos> it's the x40 part, you know
[05:20:17] <A-L-P-H-A> oh. shit. 10x18 for $1099CDN.
[05:20:24] <SWPadnos> not bad at all
[05:20:27] <A-L-P-H-A> how much at they are HF, or what was that...
[05:20:28] <A-L-P-H-A> other place?
[05:20:34] <SWPadnos> grizzly
[05:20:41] <A-L-P-H-A> $955.65USD (or so)
[05:21:21] <SWPadnos> 9x19 for $795
[05:21:29] <SWPadnos> benchtop
[05:21:39] <A-L-P-H-A> shit, that's quiet a bit difference.
[05:21:50] <SWPadnos> man, even the smallest one is 7x12
[05:21:54] <SWPadnos> $525
[05:22:12] <A-L-P-H-A> 8x12 = $439.99 :/
[05:22:34] <SWPadnos> that's cheap
[05:22:38] <SWPadnos> HF?
[05:22:40] <A-L-P-H-A> yeah
[05:22:42] <A-L-P-H-A> HF
[05:22:47] <A-L-P-H-A> HF doesn't ship to Canada though
[05:23:08] <SWPadnos> I've heard that grizzly tends to be better, but I have no personal experience with HF, so I can't compare
[05:23:35] <SWPadnos> http://www.grizzly.com/products/G9731
[05:23:48] <SWPadnos> that's pretty close to my friend's, except his has a 5HP motor
[05:23:50] <A-L-P-H-A> aren't they all made from the same factory anyways?
[05:24:03] <SWPadnos> sometimes, but they're not necessarily the identical models
[05:24:18] <SWPadnos> oh, and this one is about 33% lighter ;)
[05:24:52] <A-L-P-H-A> 9x20 - $800 from HF
[05:25:07] <SWPadnos> 9x19, $795 from grizzly
[05:25:11] <SWPadnos> close enough ;)
[05:25:24] <A-L-P-H-A> $5 for an extra inch?
[05:25:26] <A-L-P-H-A> :D
[05:25:36] <SWPadnos> it's not the size of the rod...
[05:25:37] <A-L-P-H-A> I somehow doubt there's difference.
[05:25:43] <SWPadnos> it's the magic in the wand
[05:26:13] <A-L-P-H-A> Well... I wouldn't have to pay for shipping. Shipping on that fucker to me would be expensive.
[05:26:15] <SWPadnos> which HF model?
[05:26:25] <A-L-P-H-A> so I'm paying $155 bucks more.
[05:26:43] <A-L-P-H-A> this is a local place. http://busybeetools.ca/cgi-bin/picture?&NETID=0112310316061015134&NTITEM=B2227L
[05:26:51] <A-L-P-H-A> like 10 minutes drive, with a coffee stop.
[05:27:03] <A-L-P-H-A> it's like 5 minutes away from me.
[05:27:14] <A-L-P-H-A> So shipping would be awesome, and service is easy enough too.
[05:27:26] <Jymmm> A-L-P-H-A how far are you from US border?
[05:27:30] <A-L-P-H-A> 2hrs away.
[05:27:32] <SWPadnos> shipping = drive a truck
[05:27:35] <A-L-P-H-A> there's an HF in buffalo.
[05:27:58] <Jymmm> A-L-P-H-A Well, I was thinking having it delivered to a depot and pick it up from there.
[05:28:19] <A-L-P-H-A> SWPadnos, lets say I do get a truck for FREE. Gas is going to cost me like $60bucks. Plus 5hrs of my time.
[05:28:35] <SWPadnos> what do they expect you to cut on a 9x20 lathe that only has a 3/4 HP motor?
[05:28:38] <A-L-P-H-A> Plus I'll need to buy my buddy lunch... +$15 and myself.
[05:28:43] <A-L-P-H-A> SWPadnos, alu.
[05:28:57] <SWPadnos> light cuts, I'd bet
[05:29:16] <A-L-P-H-A> alu is my friend. I don't like the hard stuff... it scares me. :) My buddy has a 2hp next door. big iron in his garage.
[05:29:28] <A-L-P-H-A> I could always replace the motor.
[05:29:29] <SWPadnos> did I mention 5HP? ;)
[05:29:45] <SWPadnos> anyway. I'll send off the mail, we'll see what happens
[05:30:12] <A-L-P-H-A> His is a 13x40... I think. I guess I could maching the bulk on his. and then move it to my mill to machine the holes.
[05:30:35] <A-L-P-H-A> SWPadnos, yeah, if he could get back to me asap, that'd be awesome. Mean time, I'm shopping around for machinists.
[05:30:48] <SWPadnos> sure
[05:30:51] <A-L-P-H-A> linuxCNC needs a job/shop forum on the site.
[05:31:09] <SWPadnos> heh
[05:31:16] <SWPadnos> none of us have working machines though ;)
[05:31:16] <A-L-P-H-A> someone should give me a user account to redo the site. www.firstfire.ca <-- my little co.
[05:31:35] <A-L-P-H-A> Well, that's NO good.
[05:35:34] <SWPadnos> not a bad looking site there
[05:36:38] <fenn> cnczone has some kinda RFQ thingy
[05:36:44] <fenn> i think you have to subscribe though
[05:38:47] <Jymmm> SWPadnos I have a working machine =)
[05:38:53] <fenn> hey shouldn't they be blurry until you mouse over them?
[05:38:55] <SWPadnos> yeah yeah
[05:43:04] <fenn> A-L-P-H-A: http://cncgear.com/joomla
[05:47:56] <A-L-P-H-A> checking
[05:48:17] <A-L-P-H-A> it's better. :)
[05:48:22] <A-L-P-H-A> EXCEPT it's not BEING USED!
[05:49:09] <SWPadnos> Alex is the main driver there, and he's at a trade show this week
[06:04:29] <sed_> dam servo motors are expensive, is there anyone who has a good deal on them out there?
[06:06:28] <A-L-P-H-A> sed_, buy in bulk. :) group orders. :)
[06:07:06] <sed_> I could buy to outfit 2 machines.. but dont think that would get me far
[06:07:07] <SWPadnos> damn - this ebay item number is a steal: 7600667478
[06:07:18] <A-L-P-H-A> you couldn't do a link? :)
[06:07:45] <SWPadnos> can't link, because for some reason, Mozilla decided to stop filling in the location bar ~/
[06:07:50] <SWPadnos> :/
[06:07:52] <SWPadnos> there

[06:08:05] <A-L-P-H-A> SWPadnos, tinyurl extension?
[06:08:08] <Jymmm> A-L-P-H-A *sigh* http://search.ebay.com/7600667478
[06:08:19] <A-L-P-H-A> I didn't even do that... I just put it into the search bar for ebay
[06:08:21] <A-L-P-H-A> :D
[06:08:32] <sed_> unless the reserve is 5k
[06:08:32] <Jymmm> http://search.ebay.com/ITEMNUMBERGOESHERE
[06:08:33] <SWPadnos> now all the pagesa re that address ;)
[06:08:43] <SWPadnos> hey - I get 404 ;)
[06:08:56] <Jymmm> Aluminum 2024 6061 Bar Stock This Whole Rack Goes
[06:09:00] <SWPadnos> (no, I didn't actually try it)
[06:09:21] <SWPadnos> that's a lot of aluminum (about a ton)
[06:09:33] <sed_> good shit..
[06:10:01] <A-L-P-H-A> I'll buy on demand. I don't have the room.
[06:10:04] <SWPadnos> if my garage were bigger (or I weren't married), I'd seriously think about it
[06:10:17] <A-L-P-H-A> but the reserve isn't even up there yet.
[06:10:22] <Jymmm> SWPadnos sell the wife, buy the aluminum
[06:10:27] <SWPadnos> hmmm - good plan
[06:10:35] <A-L-P-H-A> heh
[06:10:41] <SWPadnos> if I sell her by Friday, I save the cost of a birthday present, too
[06:10:55] <sed_> Yard metels has a good deal on Aluminum.
[06:11:08] <Jymmm> SWPadnos And you could always get two half her age at a discounted price.
[06:11:13] <A-L-P-H-A> I have two major distributors of metal near me... and I'm good with both places.
[06:11:20] <SWPadnos> hmmmmm
[06:11:23] <A-L-P-H-A> Bring in some fresh coffee... they'll give me shit for cheap. :)
[06:11:27] <A-L-P-H-A> or free.
[06:11:49] <sed_> remnats are a deal
[06:13:28] <A-L-P-H-A> damn ipod.
[06:13:34] <A-L-P-H-A> drained itself of juice.
[06:13:57] <A-L-P-H-A> though it sure is sexy... a nice shiny black 5G ipooh.
[06:14:22] <SWPadnos> I won a 512M nano last year
[06:14:32] <sed_> I dont get ipods
[06:14:33] <A-L-P-H-A> there's a 1/2gig nano?
[06:14:36] <A-L-P-H-A> shuffle or nano?
[06:14:36] <SWPadnos> haven't even plugged it into a computer
[06:14:43] <SWPadnos> shuffle, sorry
[06:14:55] <A-L-P-H-A> shuffles are just glorified usb sticks.
[06:14:57] <A-L-P-H-A> nanos are sexy.
[06:15:13] <A-L-P-H-A> black g5 ipod... the video is awesome.
[06:15:16] <SWPadnos> neither holds a candle to my M-Station ;)
[06:15:20] <A-L-P-H-A> need to find some ipod prawns fo rit.
[06:15:28] <A-L-P-H-A> what the hell is an m-station?
[06:15:35] <A-L-P-H-A> mine's 30 gigs, with VIDEO!
[06:15:43] <A-L-P-H-A> video!!! Sharp sexy video.
[06:15:44] <SWPadnos> the oldest, largest mp3 player you acn find
[06:15:51] <A-L-P-H-A> SWPadnos, lovely.
[06:15:56] <Jymmm> SWPadnos: Even if your wife is 48, you could go half that and get yourelf some of these (not work safe) http://www.trilliumeye.com/photos/24-d-06.jpg You DO remember what those are dont ya?
[06:16:00] <SWPadnos> I have 30G as well, though it takes laptop HDs, so I can upgrade that to 120G now
[06:16:17] <SWPadnos> got a pair of those
[06:16:30] <A-L-P-H-A> anyone able to do sheet metal work in here? look at like 3/16" bar stock to be bent... with a 4 holes, and a slot milled out.
[06:16:31] <SWPadnos> (and they're fine)
[06:16:36] <Jymmm> SWPadnos lol =)
[06:17:14] <A-L-P-H-A> Jymmm, those are sweet tits. my god. they're perfect.
[06:17:24] <A-L-P-H-A> I seriously wonder if they're real... :(
[06:17:42] <Jymmm> A-L-P-H-A it's a pic fomr a plastic surgeon website
[06:17:45] <SWPadnos> it's a cosmetic surgery place
[06:17:51] <A-L-P-H-A> :(
[06:17:54] <A-L-P-H-A> s h i t
[06:17:54] <SWPadnos> more examples: http://www.trilliumeye.com/results/24yrs-d-cup.htm
[06:19:16] <A-L-P-H-A> honestly... I don't know why... I'm more for a chick with REAL tits... even if they are Bs.
[06:19:53] <SWPadnos> hmmm. that reminds me. I should go to bed now ;)
[06:19:55] <fenn> heh jymmm are you suggesting swp get fake tits?
[06:20:03] <A-L-P-H-A> hey.
[06:20:14] <Jymmm> fenn: No, I'm suggesting that A-L-P-H-A get fake tits
[06:20:15] <A-L-P-H-A> http://busybeetools.ca/cgi-bin/picture?&NETID=0112310316061015134&NTITEM=B2227L <-- with this. how hard would it to convert that Z axis to CNC.
[06:20:30] <A-L-P-H-A> the top (X) axis is childs play. just the Z for full length CNC.
[06:23:52] <SWPadnos> good night, guys
[06:23:52] <SWPadnos> SWPadnos is now known as SWP_Away
[06:23:52] <A-L-P-H-A> night SWP_Away.
[06:23:52] <fenn> nighy night
[06:23:52] <SWP_Away> booby time
[06:23:52] <SWP_Away> oops, I mean, sleep time
[06:23:54] <Jymmm> G'Night SWP_Away
[06:24:40] <fenn> A-L-P-H-A: a lot of the things that make something annoying to convert to CNC aren't readily apparent
[06:25:34] <fenn> there's a lot more room for upgrades on a lathe than a mill
[06:25:41] <fenn> extra "stuff" that does something
[06:27:39] <A-L-P-H-A> fenn, see, with my current lathe, I'm stuck at like 93mm(Z) x 100mm (X)
[06:28:00] <A-L-P-H-A> mind you, it does precision work. But I'm like stuck for larger stuff.
[06:28:04] <fenn> ah, on a lathe Z is the long axis (parallel to spindle)
[06:31:26] <A-L-P-H-A> yes.
[06:31:27] <A-L-P-H-A> I'm thinking maybe mod that lathe I posted (busybee) to do something like this. http://www.cnczone.com/gallery/data/500/986tn_P1010004.JPG
[06:34:26] <A-L-P-H-A> I like these things. http://winn.com/bs/disclaimer.html
[06:35:53] <fenn> heh electromagnetic radiation from nuclear blasts
[06:48:56] <Jymmm> nuclear blasts, cell phones, same diff.
[06:54:19] <fenn> jymmm wha a great idea - the nuclear cellphone!
[06:58:27] <Jymmm> =)
[06:58:42] <Jymmm> G'night Folks!
[10:51:28] <anonimasu> hello
[13:32:08] <SWP_Away> SWP_Away is now known as SWPadnos
[13:38:49] <Jymmm> Hornin Folks!
[13:38:55] <Jymmm> Mornin Folks!
[13:40:15] <anonimasu> morning
[13:41:12] <anonimasu> what's up?
[13:41:14] <fenn> jorregelt
[13:42:32] <anonimasu> hat`?
[13:44:25] <fenn> sorry i dont speak hungarian
[13:44:25] <Jymmm> gonna order some tooling... one being an engraver bit.... 60 deg .01 tip
[13:45:19] <anonimasu> err what..
[13:45:39] <Jymmm> trying to find a pic (theri damn website is being worked on)
[13:46:24] <anonimasu> I am finishing my gps interop stuff for work
[13:46:28] <fenn> .01 tip meaning .01" is the minimum feature size or the maximum feature size?
[13:46:34] <anonimasu> waiting for some plcs to ship
[13:47:07] <Jymmm> https://www.onsrud.com search for 37-03
[13:47:52] <Jymmm> https://www.onsrud.com/xdoc/plastics
[13:47:57] <Jymmm> then search
[13:48:06] <Jymmm> what a fscked up website
[13:48:07] <fenn> bad website design
[13:48:18] <Jymmm> and this is their NEW design too
[13:48:19] <fenn> the whole thing is ssl?
[13:48:28] <fenn> you should write a complaint
[13:48:41] <fenn> bad website designers need to be punished
[13:48:42] <Jymmm> I'll just call the outside sales guy
[13:48:45] <fenn> it's self defense
[13:49:18] <Jymmm> anyhow... do you see it?
[13:49:36] <fenn> yeah
[13:50:21] <Jymmm> the .005 is $35, so forget that, I'm just playing. But just not sure on the width I should get
[13:51:06] <fenn> it says $20.35
[13:51:11] <Jymmm> Hmmmm, they havent' updated the pricing.... maybe I SHOULD get it =)
[13:51:38] <Jymmm> but might be a tad weak in the tip
[13:52:08] <Jymmm> you guys do any engraving?
[13:52:17] <fenn> not yet
[13:52:21] <Jymmm> they're good for plastic aluminum and brass
[13:52:23] <anonimasu> same ;)
[13:52:45] <Jymmm> does anyone have any engraved name badges?
[13:52:55] <Jymmm> I need the width =)
[13:52:58] <anonimasu> hm, yes somewhere..
[13:53:04] <fenn> are they all the same width?
[13:53:07] <SWPadnos> like on a door, or to pin on your jacket?
[13:53:14] <fenn> i'd think people with long names would have longer badges
[13:53:14] <SWPadnos> or a desk ...
[13:53:18] <Jymmm> SWPadnos jacket would be a good start
[13:53:29] <anonimasu> usually you size the stuff from the longest name..
[13:53:32] <Jymmm> knowing desk/office door palte would be good too
[13:53:36] <fenn> the longest name huh
[13:53:44] <anonimasu> and make the badges standardized..
[13:53:49] <SWPadnos> about the size of a business card, or for nice ones, much smaller, like 1/2" high, 2-3" wide
[13:53:59] <Jymmm> But the engraving industry uses the panton arm, not cnc
[13:54:02] <anonimasu> making a run for a whole office would be pretty hard..
[13:54:08] <Jymmm> so the width is the width of the tip
[13:54:45] <Jymmm> notice 37-19, it's a set off all the tip widths
[13:56:23] <Jymmm> So, does .010" flat tip sound 'ok'?
[13:56:50] <Jymmm> too narrow?
[13:57:19] <SWPadnos> .010 is about 2/3 point, to put it in text terms
[13:57:46] <fenn> you can cleanly engrave 2 point text with a .010 tip?
[13:57:59] <fenn> or .010 is the size of a 2 point letter
[13:58:05] <SWPadnos> think about the font / point size, figure out the stroke width (with Corel Draw or something), then get the width you need
[13:58:17] <SWPadnos> no, it's a thickness of 0.666 points
[13:58:20] <Jymmm> Ok, assume most of these are 1" tall x 3" wide... http://images.google.com/images?q=engraved%20name%20badge&sa=N&tab=wi
[13:58:26] <SWPadnos> I think 1 pt is 1/72 inch
[13:58:34] <Jymmm> SWPadnos correct
[13:58:47] <fenn> so 12 point Times New Roman is ... how big?
[13:58:57] <SWPadnos> 12/72 inck, or 1/6 inch high
[13:59:14] <Jymmm> http://www.pharmex.com/images/EB-101.jpg
[13:59:38] <fenn> i dunno Jymmm it looks like you have a lot of room for interpretation
[13:59:49] <Jymmm> what would you say the lettering height is there?
[14:00:15] <fenn> http://images.google.com/imgres?imgurl=http://www.stamp-connection.com/images/products/mugshots/prime_itagm.gif&imgrefurl=http://www.stamp-connection.com/products/ITagM.html&h=154&w=144&sz=11&tbnid=lhZSA-IMw8nm0M:&tbnh=91&tbnw=85&hl=en&start=20&prev=/images%3Fq%3Dengraved%2Bname%2Bbadge%26svnum%3D10%26hl%3Den%26lr%3D%26ie%3DUTF-8%26safe%3Doff%26sa%3DN
[14:00:19] <fenn> doh!
[14:00:28] <fenn> anyway they are all 3" wide on that site
[14:01:16] <Jymmm> This is common http://www.stamp-connection.com/products/ITag%201%20x%203.html
[14:01:43] <Jymmm> See the Roby badge?
[14:02:18] <Jymmm> I see subtext, just wondering if I could do both main and subtext with the same tool?
[14:02:33] <fenn> yeah with your fancy engraving software why not
[14:02:54] <SWPadnos> it'll look a bit weird, unless you do multiple passes on the larger text
[14:03:06] <fenn> i wonder how you do braille dots
[14:03:15] <Jymmm> fenn relief
[14:03:21] <fenn> glue little beads in divets or something?
[14:03:26] <fenn> ll ADA signage MUST have the "dome-shaped" tactile Braille by June, 2006.
[14:03:59] <Jymmm> SWPadnos I still not sure which tip to get though
[14:04:28] <Jymmm> .01 will get into tight spaces, but will that be useful
[14:04:33] <SWPadnos> I think that'll be found by experimentation. I'd get the set and see what works for which size (and style) of text
[14:04:36] <fenn> what is the advantage of bigger tip size?
[14:04:51] <fenn> and isn't 90 degree more common?
[14:04:52] <SWPadnos> faster engraving
[14:04:54] <fenn> and stronger
[14:06:04] <fenn> maybe you should ask onsrud :)
[14:06:14] <Jymmm> already did
[14:06:20] <Jymmm> .01
[14:06:52] <fenn> i'd go with .01 then
[14:07:03] <Jymmm> I want to cut out the plastic too, not sure if I can with this tip
[14:07:20] <Jymmm> beveled of course
[14:07:39] <fenn> * fenn goes back to reading about attiny13
[14:07:47] <fenn> two pwm channels woohoo!
[14:07:56] <Jymmm> fenn go get a butterfly!
[14:08:03] <fenn> no way
[14:08:39] <SWPadnos> eewww - I'm not sure I could live without the extra lpm variants, plus the multiplier
[14:09:40] <fenn> all i have to do is count encoder pulses and maybe pwm the motors and talk to the motherchip
[14:10:12] <fenn> dunno whether to do SPI with a chip select or use i2c
[14:11:17] <Jymmm> fenn are you interconnecting multiple chips via i2c?
[14:11:30] <fenn> yah maybe
[14:11:46] <Jymmm> go with i2c, nice protocol
[14:12:43] <SWPadnos> look closely at the PWM features. I'm not sure which one they put in the tiny parts, but you may find that the smaller mega chips have features you need
[14:13:21] <Jymmm> fenn: http://www.semiconductors.philips.com/acrobat_download/literature/9398/39340011.pdf
[14:13:56] <fenn> what should i be looking for?
[14:14:11] <Jymmm> fenn: Philips wrote i2c, that's the specs
[14:14:16] <fenn> Jymmm: it depends on how much code i need to use it
[14:14:31] <fenn> i'm polling so i have to do stuff in tiny chunks
[14:15:04] <fenn> SWPadnos: what should i be looking for as far as pwm features?
[14:15:25] <SWPadnos> well, the Mega PWM has multiple outputs that can be synchronized
[14:15:37] <SWPadnos> it can run faster for a given clock speed
[14:15:41] <SWPadnos> has higher resolution
[14:15:47] <SWPadnos> (and programmable resolution)
[14:15:52] <Jymmm> bit rate 400kbps, High speed bitrate 3.4Mbps, 10bit addressing (1024 slave addresses)
[14:16:22] <SWPadnos> just things to think about - you should be careful to get one that does what you need in hardware, since you'll need to use software for I2C and other stuff
[14:17:16] <SWPadnos> i2c isn't really meant for off-board communication though
[14:17:32] <Jymmm> fenn whatcha makin?
[14:23:49] <fenn> SWPadnos: i know someone who communicates like 10 feet with unshielded i2c
[14:24:09] <fenn> he just slows down the data rate and filters it
[14:24:25] <SWPadnos> that's OK for personal projects. I usually think in terms of things I'd charge for
[14:25:05] <fenn> jymmm an 8 axis servo control that plugs into the parallel port
[14:25:20] <fenn> and doesn't cost an arm and a leg, and is open-source
[14:25:31] <fenn> and maybe i'll enter it into the avr design competition
[14:28:51] <Jymmm> fenn: bsd license,
[14:29:44] <Jymmm> fenn at least part of it is.
[14:30:08] <Jymmm> fenn might save some typing =)
[14:30:52] <fenn> i think avrlib has something like that
[14:31:04] <Jymmm> When I worked at Philips, I was jsut amazed at there usage of I2C is all.
[14:31:31] <fenn> but like i said i'm going to be doing polling, so i need to break stuff into chunks
[14:32:15] <Jymmm> is that necessary (I dont know)?
[14:32:27] <fenn> #define avr_i2c_wait() while(!(TWCR & (1<<TWINT))) ;
[14:32:35] <fenn> that doesn't look like what i want
[14:32:56] <fenn> (sits and does nothing until it's done)
[14:32:57] <SWPadnos> well, they had to use it a lot, they invented it
[14:33:28] <Jymmm> SWPadnos sure, but they did a damn fine job of it too =)
[14:33:44] <fenn> yep
[14:33:50] <fenn> it's pretty straightforward
[14:33:59] <SWPadnos> oh yeah, I remember when they first came out with it - like in 1989-90 or so
[14:34:14] <Jymmm> I just AHTE polling, fscking USB crap
[14:34:14] <SWPadnos> on the little 8051-like chips, the 751 and 752
[14:34:18] <Jymmm> HATE
[14:34:41] <fenn> why do we use rs232? it sucks!
[14:34:43] <SWPadnos> USB is dumb for many reasons, not just polling ;)
[14:34:52] <fenn> rs485 or something is much better
[14:34:57] <Jymmm> fenn I LOVE my uarts!
[14:35:08] <SWPadnos> RS232 is actaully very good, in the situations it was designed for
[14:35:11] <jepler> SWPadnos: USB sure seems to work, I have a bunch of usb devices and they all do what they're supposed to.
[14:35:20] <Jymmm> I made sure me laptop had serial port when I bough tit
[14:35:32] <fenn> what was rs232 designed for?
[14:35:37] <SWPadnos> true, there's a lot that can be done with USB, but I still think the architecture is silly
[14:35:40] <jepler> from mice with smooth-feeling position updates to hard drives that transfer 20MB/s
[14:35:47] <Jymmm> jepler try getting live raw data from gps via usb - it's crap
[14:35:50] <SWPadnos> it's a lot like the '386 - stupid, but a lot has been done with it
[14:36:14] <anonimasu> insanity polling
[14:36:15] <anonimasu> :)
[14:36:15] <jepler> Jymmm: oh, I've done that too .. the only problems there I chalk up to Microsoft Windows XP
[14:36:25] <SWPadnos> fenn, fairly short-haul, point to point, common ground communications
[14:36:28] <Jymmm> jepler: nix too
[14:36:30] <jepler> (half the time it thinks I've plugged in an insane mouse, not a GPS)
[14:36:42] <Jymmm> jepler lol
[14:36:51] <SWPadnos> funny thing about XP64 - it doesn't support Logitech USB mice
[14:36:56] <SWPadnos> at least, not my MX510
[14:37:03] <anonimasu> I so hate windows
[14:37:23] <Jymmm> jepler Well, I'm lucky that my laptop, gps, and radio all have serial ports =)
[14:37:23] <anonimasu> did I mention I am coding .net right now ^_^
[14:37:25] <SWPadnos> I had to plug in a Microsoft mouse to get it to work (and there had to be a mouse present to even booth the installer)
[14:37:33] <cradek> funny thing about XP64 - people still pay good money for an operating system
[14:37:37] <jepler> I'm getting closer and closer to "windows free" at home. I still have one, but it's never on anymore
[14:37:54] <SWPadnos> cradek, yeah, that is funny
[14:38:18] <anonimasu> wtf.
[14:38:20] <SWPadnos> I just wish that I didn't have to be compatible for my customers and development tools sake
[14:38:29] <anonimasu> * anonimasu does too
[14:38:38] <anonimasu> running games in linux emulated works too
[14:38:58] <SWPadnos> I may spend the cash on VMWare, and just use emulated Win2K until eveything needs XP
[14:39:06] <jepler> anonimasu: with $$$ software like transgaming, or with free emulation software?
[14:39:08] <SWPadnos> then give up and start selling lemonade in hawaii
[14:39:18] <anonimasu> jepler: transgaming
[14:39:48] <anonimasu> jepler: winex will probably work too
[14:39:55] <anonimasu> but the transgaming stuff is very very fast..
[14:40:02] <jepler> For awhile I was signed up for the transgaming "subscription", then I realized it was a huge ripoff and I never actually used the software
[14:40:05] <cradek> a year ago I installed win2000 in qemu
[14:40:39] <SWPadnos> I never got qemu to network on my opteron machine
[14:40:41] <cradek> networking and all
[14:40:47] <cradek> huh
[14:40:49] <SWPadnos> but Win2k was pretty fast under VMWare
[14:40:55] <cradek> well I did...
[14:41:00] <cradek> it's been a long time ago though.
[14:41:07] <SWPadnos> yeah - it seems like it just "shoulda worked"
[14:45:17] <giacus> anyone here familias with css sheets ?
[14:45:21] <giacus> familiar
[14:46:28] <Jymmm> giacus no, why?
[14:46:35] <giacus> http://www.sanavia.it/nvuitalia/demos/frames/frameSimulate.html
[14:46:41] <giacus> I working around that sample
[14:47:01] <giacus> I'd like to understand how to add an image background to the top 'frame'
[14:47:14] <giacus> if using html separated page or the css
[14:47:26] <Jymmm> giacus you REALLY should avoid using frames
[14:47:35] <giacus> theyre not frames ..
[14:47:39] <anonimasu> tables + php is really nice
[14:47:55] <Jymmm> anonimasu dont let the css xealots hear you
[14:48:01] <Jymmm> zealots
[14:48:03] <giacus> :)
[14:48:19] <anonimasu> Jymmm: I dont care too much about zealots.. :9
[14:48:20] <anonimasu> :)
[14:48:27] <giacus> Jymmm: thyre pseudo-frames
[14:48:32] <anonimasu> * anonimasu nods
[14:48:46] <Jymmm> giacus I see that now, thought you meant <Frames>
[14:49:07] <Jymmm> gimme a sec
[14:49:09] <anonimasu> should be good stuff about it on google
[14:49:53] <Jymmm> giacus ok, you have a div there, and you want a background image?
[14:50:02] <giacus> uhm
[14:50:06] <giacus> let me check
[14:50:29] <giacus> looking at the page source
[14:50:39] <giacus> there's <!-- Top Header portion of page - remains unchanged -->
[14:50:39] <giacus> <div id="mastHead">
[14:50:40] <giacus> <h1>Simulating Frames with CSS</h1>
[14:50:47] <Jymmm> giacus I just said that
[14:50:57] <Jymmm> giacus I was asking what you want to do
[14:51:25] <giacus> well, I want to set backgrounfd image but only for the top side
[14:51:34] <giacus> in that code
[14:51:44] <Jymmm> giacus well, gimme the link to the image you wanted to use?
[14:52:02] <giacus> http://giacus.altervista.org/
[14:52:09] <giacus> could be that or similar
[14:52:14] <Jymmm> giacus that's not a image
[14:52:28] <giacus> wjy not ?
[14:52:31] <Jymmm> it'll end in .jpg orwhatever
[14:52:32] <giacus> why
[14:52:44] <giacus> giacus_testata.jpg
[14:52:57] <Jymmm> giacus I want the FULL url
[14:53:14] <giacus> http://giacus.altervista.org/giacus_testata.jpg
[14:55:17] <giacus> in order to get a nice look website I have to learn css :/
[14:55:34] <giacus> is should be doable in a couple of hours
[14:55:37] <Jymmm> background-image: url('http://giacus.altervista.org/giacus_testata.jpg');
[14:55:43] <cradek> if your content is good, people will forgive your look
[14:55:47] <Jymmm> add that just below:
[14:55:55] <giacus> cradek: I know that
[14:55:57] <Jymmm> border: 2px solid #0000DD;
[14:56:33] <giacus> cradek: a bit of smoke in the eyes could be nice :P
[14:56:35] <Jymmm> giacus: FYI... http://www.w3schools.com/css/default.asp
[14:56:39] <cradek> I know from experience with my ugly site!
[14:56:59] <cradek> s/ugly/simple/
[14:57:02] <giacus> im tryng to restiling it using nvu
[14:57:11] <giacus> and vim, better !
[14:57:23] <giacus> but im not so familiar with html an css language
[14:57:32] <giacus> thats the problem :(
[14:57:48] <giacus> Jymmm: looking
[14:58:28] <giacus> cradek: sometime (often) peoples is impressed by look and feel
[14:58:33] <giacus> after from contents
[14:58:39] <giacus> I know that ..
[14:59:03] <giacus> Jymmm: well, I tried that line before
[14:59:24] <giacus> result I got i the background is replicated everywhere
[14:59:31] <giacus> also in the other 'frames'
[14:59:43] <giacus> so,, waht the right section for that ?
[15:00:08] <giacus> looking at that code
[15:00:18] <giacus> I think there are 2 ways to get it
[15:00:32] <giacus> set a bacground in a separated html page and link it
[15:00:34] <giacus> or
[15:00:40] <giacus> use the css sheet
[15:00:47] <giacus> that could be better maybe
[15:01:00] <giacus> or not ..
[15:01:08] <Jymmm> giacus try what I gave you please
[15:01:17] <Jymmm> I'd liek to see it
[15:01:25] <giacus> beacuse that image should appear always and only in the top side
[15:02:02] <giacus> Jymmm: have you firefox installed ?
[15:02:14] <giacus> I can tell you in what section I tried it
[15:02:24] <Jymmm> I'd like you to try it now.
[15:02:27] <giacus> so, if you can look at the source code of the page
[15:03:18] <giacus> Jymmm: look this
[15:03:22] <giacus> http://www.sanavia.it/nvuitalia/demos/frames/frameSimulate.css
[15:03:34] <giacus> I changed the line background-color: #CCC;
[15:03:52] <giacus> in the #mastHead section
[15:04:06] <giacus> setting the backgroun image as you sayd
[15:04:25] <giacus> the problem is, the image was replicated and showed in all frames
[15:04:38] <giacus> not in the top only I need
[15:04:40] <giacus> as
[15:04:49] <cncuser> hi folks
[15:04:54] <giacus> hey cncuser
[15:04:55] <jepler> hi cncuser
[15:05:42] <cncuser> hi giacus, jepler :)
[15:05:53] <cncuser> jepler: i noticed something with axis
[15:06:42] <jepler> cncuser: what's that?
[15:06:51] <cncuser> jepler: if i change the naming of the axis. (ini a -> q for example) i can see that in the renderingwindow
[15:07:13] <cncuser> jepler: but i dont see it on the controlpanel. the axis still has the.. seems like hardcoded naming
[15:07:55] <jepler> cncuser: yes, that's true.
[15:08:43] <cncuser> jepler: is it easz to change ? seems zou allreadz use the ini naming. so mazbe just a variable ?
[15:09:00] <cncuser> ok, this is what it looks if i type on a us keyboard :)
[15:09:24] <cncuser> streettalk
[15:09:25] <jepler> cncuser: it could be fixed but IMO an additional problem is the keyboard shortcuts for those axes
[15:09:37] <jepler> Yeah, I have similar problems when I go to germany and try to use the internet cafe
[15:09:52] <cncuser> jepler: right
[15:10:29] <cncuser> jepler: you could add that feature to the next rellease :) add a axis naming / shortcuts config :)
[15:11:02] <jepler> no. I don't indend to add shortcut configuration to axis.
[15:11:09] <cncuser> ok :)
[15:11:38] <cncuser> jepler: is dont mind this thingz. i just seen it with a config and thought this isnt right. :)
[15:11:43] <jepler> you just won't be able to activate axis Q just by typing q.
[15:11:58] <cncuser> shure
[15:12:06] <cncuser> :)
[15:12:13] <jepler> well I just put this in the BUGS file
[15:12:23] <jepler> so at least it's written down somewhere
[15:12:27] <cncuser> :)
[15:12:35] <cncuser> been there, seen that
[15:12:37] <cncuser> :)
[15:12:49] <cncuser> well, anzthing happened ?
[15:12:54] <jepler> not much with axis
[15:12:55] <cncuser> i have 15 minutes left :)
[15:13:04] <jepler> I'm working on the servo version of my etch-a-sketch though
[15:13:11] <cncuser> harhar
[15:13:25] <jepler> last night I got the motors to turn at different speeds based on a PWM signal from the parallel port
[15:13:28] <cncuser> most accurate etchasketch ever
[15:14:05] <cncuser> without a controllerbox ?
[15:14:11] <cncuser> is it that low power ?
[15:14:16] <jepler> I think it'll be about 1800 encoder counts per inch which is a big increase from my current 68/inch with steppers
[15:14:17] <cncuser> a ok
[15:14:17] <giacus> Jymmm: got it working ;P
[15:14:18] <cncuser> servo
[15:14:20] <jepler> let me show you my schematic
[15:14:21] <cncuser> controlol
[15:14:30] <jepler> http://emergent.unpy.net/projects/01142347802
[15:15:35] <jepler> cncuser: the chip takes signals from the parallel port and runs the servo motors. The encoders are read by the parallel port.
[15:15:51] <cncuser> l298 ?
[15:15:54] <jepler> yes, L298
[15:16:21] <cncuser> a it a motordriver :)
[15:16:40] <jepler> so for X axis, emc puts direction on L298 pin 5, inverted direction on pin 7, and a PWM signal on ENABLE_A
[15:16:41] <cncuser> ic
[15:16:45] <jepler> L298 is a dual H bridge
[15:16:53] <cncuser> im no EE
[15:16:59] <cncuser> i dont have much clou at all
[15:17:26] <jepler> oh .. well, a H bridge with PWM input is sufficient to make a DC servo turn in either direction at varying speeds.
[15:17:49] <cncuser> i seperate those things bz usage not by how it works or what the effects are that are used :)
[15:18:26] <cncuser> jepler: icic. so the h bridge is kind of ampiliefer ?
[15:18:31] <jepler> cncuser: yes
[15:19:11] <jepler> cncuser: It can hook either side of the motor coil to V+ or to GND, depending on the inputs. So you can turn the motor either way.
[15:20:20] <jepler> here's the datasheet of the l298: http://www.st.com/stonline/books/pdf/docs/1773.pdf
[15:20:39] <jepler> figure 6 shows how you can use it to control a DC motor
[15:20:49] <cncuser> i wish i did more during the 1 year at ee/school... i think it reallz didnt interest me at all when triangle and starcircuits where discussed :) 2nd month or so
[15:21:14] <jepler> I didn't take anything like that at school .. I've just been learning as a hobby for the past 2 years
[15:21:28] <jepler> I still struggle with the basic stuff like Ohm's Law
[15:21:50] <cncuser> jepler: im on that train too :) but i think it will take 10 zears till i can do anzthing usable. right now its all bad black magic.
[15:21:52] <jepler> but I can copy from datasheets into eagle real good
[15:22:02] <cncuser> hehe
[15:22:07] <cncuser> i do that too
[15:22:50] <cncuser> but, i connect transistors the wrong waz, also diodes, it takes me hours to find ressistors and i have no clou how pullup resistors work or whz
[15:22:57] <rayh> never could remember ohms law e=mc or what?
[15:23:05] <cncuser> harhar
[15:23:12] <jepler> no .. pv=nrt
[15:23:19] <jepler> (ohm's ideal gas law)
[15:23:28] <fenn> ohm was a busy fellow huh
[15:23:58] <jepler> speaking of electronics, I was trying to understand the "current mirror".
[15:24:53] <cncuser> rigth now (because of the lack of internet) i triy to build a digitaljoystickinterface for the parallelport. it so plain stupid, nothing fancz. but i dont have a clou how this could work. i built it. aqnd it doesnt work. 1000s of other people have made that and it works
[15:25:01] <rayh> is the ohm's gas law relevant to the volume of smoke issued from ic's?
[15:25:22] <fenn> no, smoke is not a gas, it's a colloid
[15:25:43] <fenn> that's why you can fit so much smoke into a tiny volume like a transistor
[15:26:28] <fenn> manufacturers spend billions of dollars researching new ways of compressing magic smoke
[15:26:36] <cncuser> http://www.charmed.com/txt/joystick-parport.txt the gamecon thingy.... a bunch of diodes one resistor.... the magical pullup resistor again. which i think just doesnt work because it knows i dont understand what its good for.
[15:26:54] <fenn> cncuser why not use the joystick port?
[15:27:01] <fenn> jmk just submitted a driver the other day
[15:27:22] <fenn> not sure exactly what it does though
[15:27:25] <cncuser> fenn: i got a bunch of competition pros and other arcadestzle jozsticks back from c64 and amiga days
[15:28:05] <cncuser> whatever, different problem, different station.
[15:28:18] <cncuser> hu, still 2 minutes left
[15:28:30] <jepler> cncuser: try this explanation of the pull-up resistor. http://www.seattlerobotics.org/encoder/mar97/basics.html
[15:28:33] <cncuser> anzone wnat to tell me what a pullupresistor is good for in 1>30 mins _
[15:28:37] <cncuser> hehe
[15:28:52] <fenn> if a pin has nothing driving it, noise can make it fluctuate to just about any voltage
[15:29:19] <fenn> you set it to a particular voltage by putting a high value resistor (like 100k) inbetween the pin and your voltage
[15:29:58] <fenn> then when you want to set it to ground, you can sink current faster than the resistor can pass it so the pin ends up at ground
[15:30:08] <cncuser> jepler: thanks, i dont understand a word :)
[15:30:12] <cncuser> bye folks
[15:31:13] <fenn> amazing that you can write 3 pages about pullup resistors
[16:13:55] <giacus> well, I got the backgrond working for the top frame
[16:14:25] <giacus> now I should link some image area to urls
[16:14:32] <giacus> Jymmm: any idea ? :P
[16:15:05] <giacus> I dont want any rollover manu
[16:15:07] <giacus> menu
[16:15:13] <giacus> just a click area
[16:15:58] <giacus> http://archivist.incutio.com/viewlist/css-discuss/32952
[16:16:04] <giacus> this maybe could work ..
[16:17:04] <giacus> but .. it seem doesn't appear to work in I.E. 5.0 & 5.5.
[16:28:10] <anonimasu> hm, does anyone have any experience with vaccum stuf?
[16:28:10] <anonimasu> f
[16:29:54] <fenn> high vacuum or low vacuum?
[16:30:15] <anonimasu> clamps
[16:30:16] <anonimasu> and stuff
[16:30:29] <anonimasu> I took the plunge and ordered a ejector
[16:30:41] <fenn> what's this ejector for?
[16:30:43] <anonimasu> 35$
[16:31:07] <fenn> if you're just making vacuum there are easier ways
[16:31:18] <anonimasu> hm, how?
[16:31:19] <fenn> i used a venturi attached to a faucet
[16:31:31] <anonimasu> I am limited in air for my app..
[16:31:35] <anonimasu> like 4l/min
[16:31:41] <anonimasu> but I dont need lots of vaccum either..
[16:32:09] <anonimasu> fenn: got any drawings of that?
[16:32:19] <anonimasu> or is it just a venturi + a secondary pipe?
[16:32:48] <anonimasu> p-|-o
[16:32:53] <fenn> its really easy to make
[16:32:54] <anonimasu> s
[16:33:02] <anonimasu> something like that and the venturi at the outlet
[16:33:03] <fenn> i read it in a methamphetamine production book
[16:33:14] <anonimasu> lol!
[16:33:46] <fenn> i took a copper pipe and smooshed it flat, and hooked it to a hose faucet, then used an outer pipe to hold a bic pen body at 90 degrees to the water stream
[16:33:55] <fenn> then adjust the pen body in/out until it sucks
[16:34:09] <fenn> i used it to vacuum-clamp fiberglass molds
[16:34:23] <anonimasu> I dont have any water at all
[16:34:24] <anonimasu> :)
[16:34:26] <fenn> ah
[16:34:34] <giacus> hahaha found it !http://www.constile.org/tips/emulare_le_immagini_mappate_con_i_css/emulare_le_immagini_mappate_con_i_css.html
[16:34:34] <anonimasu> and compressed air's cheaper..
[16:34:44] <giacus> damn earth I've under foots :D
[16:35:14] <anonimasu> but I've got a real one on order..
[16:35:22] <anonimasu> if it works nicely I'll copy it and size it down..
[16:35:32] <giacus> :P
[16:35:36] <fenn> try just sticking a tube at 90 degrees to an airstream too
[16:35:44] <anonimasu> they had 10l/min ones..
[16:35:54] <anonimasu> hm, I did the other way then I tried..
[16:36:05] <fenn> the other way?
[16:36:13] <anonimasu> air pipe -|-T-- |
[16:36:15] <anonimasu> like that..
[16:36:23] <fenn> i cant understand that
[16:36:23] <anonimasu> when I tried before but that was for coolant..
[16:36:47] <anonimasu> I had the pipe with the input air protruding and I fed it with coolant before the input
[16:36:55] <anonimasu> it sucked quite a bit..
[16:37:01] <anonimasu> in many ways
[16:38:03] <fenn> ok well.. try something like this
[16:38:08] <fenn> =>
[16:38:11] <fenn> |
[16:38:20] <anonimasu> yeah
[16:38:52] <anonimasu> should work.
[16:39:08] <anonimasu> the ejector I'm getting delivered gives 80% vaccum
[16:39:09] <anonimasu> ;)
[16:39:25] <anonimasu> pretty brutal
[16:39:32] <fenn> i dont really know
[16:39:51] <fenn> what's the air pressure at mach 1?
[16:40:04] <anonimasu> no clue
[16:41:09] <anonimasu> http://en.wikipedia.org/wiki/Airspeed
[16:41:16] <fenn> heh already reading it
[16:41:53] <anonimasu> I'll be back in a moment going to cut a tube...
[16:42:25] <fenn> 28372 something or others
[16:42:47] <fenn> about 41psi if it's pascals
[16:44:14] <fenn> wish i had a "units" that solved equations and gave me an answer with some value of units
[16:44:42] <anonimasu> yeah
[16:44:43] <bill2or3> google will do some tf that, for simpler stuff.
[16:44:55] <anonimasu> I think #math has a matlab bot
[16:45:23] <fenn> Vi=sqrt((Pt-P)/.5Po) solve for Pt-P
[16:45:47] <fenn> yeah ##engineering has it too
[16:45:52] <fenn> mathematica
[16:45:55] <anonimasu> is there such a channel?
[16:45:59] <fenn> there is now
[16:46:09] <anonimasu> nice
[16:46:18] <fenn> we mainly talk about electronics and giant robots
[16:46:22] <anonimasu> hehe
[16:46:23] <anonimasu> nice
[16:46:29] <anonimasu> I should be there :)
[16:46:36] <fenn> its not too busy but it's picking up
[16:46:56] <anonimasu> everyone loves robots isnt that right?
[16:47:11] <bill2or3> especially killer robots.
[16:47:15] <anonimasu> yeah
[16:47:46] <fenn> er i mis-spoke
[16:47:50] <anonimasu> I've spent all day hunting for sensors
[16:47:52] <fenn> when i say giant robots i mean exoskeletons
[16:48:02] <anonimasu> oh :(
[16:48:19] <anonimasu> still neat
[16:48:38] <anonimasu> http://www.heason.com/products/linear_motors/linear_motors_1001942168/linear_motors_1001942168_1002019092/linear_motors_1001942168_1002019092.html
[16:49:06] <fenn> i reserve talk of giant robots for #robotics :)
[16:49:42] <anonimasu> hehe
[16:49:47] <fenn> that seems silly.. why not use a high torque servo
[16:50:03] <anonimasu> I dont need the torque
[16:50:13] <anonimasu> ;)
[16:50:13] <fenn> a low torque servo then
[16:50:21] <anonimasu> still that adds drive electronics
[16:51:02] <fenn> and a voice coil doesn't need drive electronics?
[16:51:46] <anonimasu> nope not for the motion I'd want..
[16:51:56] <anonimasu> just something to limit current/voltage
[16:52:53] <anonimasu> fixed motion from a to b with hard stops..
[16:53:48] <fenn> anonimasu: you should join ##microcontrollers so we can convert you to AVR
[16:53:57] <anonimasu> fenn: I got the devel board on my desk..
[16:54:01] <anonimasu> ;)
[16:54:05] <fenn> bah who needs a devel board
[16:54:11] <fenn> i got the breadboard on my bench
[16:54:18] <anonimasu> devel board/programmer
[16:54:24] <fenn> i got your 4 resistors right here
[16:54:25] <anonimasu> I bought one years ago..
[16:54:28] <anonimasu> ;)
[16:55:30] <anonimasu> never made any real thingie with it
[16:56:41] <fenn> i am supposed to be making an encoder counter but i'm wasting away on irc instead
[16:57:14] <anonimasu> hehe
[16:58:17] <anonimasu> hm
[16:58:56] <anonimasu> fenn: the servo idea werent too bad..
[16:59:57] <anonimasu> servos are really cheap
[17:00:31] <fenn> are you thinking RC servo or industrial servo?
[17:00:36] <anonimasu> rc servo..
[19:15:55] <anonimasu> iab
[19:17:13] <bill2or3> Mmmservo
[19:18:38] <anonimasu> :)
[19:41:49] <gene> Hello all

[20:07:33] <alex_joni> ouch... your cvs died
[20:07:47] <bpmw> Hi Guys!
[20:08:19] <fenn> how do i fix that?
[20:08:31] <alex_joni> fenn: no idea :(
[20:08:39] <alex_joni> it should timeout eventually
[20:08:51] <bpmw> Just A quick Question, has anyone got Emc2 to build on Fedora Core 4?
[20:08:53] <fenn> see if it works now
[20:09:00] <fenn> yeah i'm running it right now
[20:09:08] <alex_joni> cvs commit: [20:08:50] waiting for fenn's lock in /cvsroot/emc/emc2/bin
[20:09:13] <fenn> (that last message was to bpmw)
[20:09:24] <alex_joni> fenn: I know ;)
[20:09:43] <alex_joni> fenn: let it be for now.. it'll timeout eventually
[20:10:12] <fenn> that was at least a couple hours ago
[20:10:18] <fenn> oh well
[20:10:32] <alex_joni> :-/
[20:10:43] <Jymmm> loginout,login,logout
[20:10:51] <Jymmm> logout,login,logout
[20:11:03] <alex_joni> Jymmm: not for devel cvs
[20:11:27] <Jymmm> alex_joni logging out should release any locks, no?
[20:11:28] <fenn> i ran cvs again with no problems, no difference
[20:11:40] <alex_joni> Jymmm: there is no logout from cvs
[20:12:10] <alex_joni> fenn: yeah, cvs up works here too, but commiting something to bin/ doesn't work
[20:12:32] <Jymmm> ok, disconnect, connect, dosconnect.
[20:12:42] <alex_joni> disconnect from what?
[20:12:49] <Jymmm> the server
[20:12:53] <fenn> what if i committed something to bin? would it deny me because i have th lock?
[20:13:08] <alex_joni> the lock is on SF's machine from the stuff fenn did a few hours ago
[20:13:11] <alex_joni> fenn: yes
[20:13:28] <SWPadnos> fenn, did you just upgrade your system?
[20:13:35] <bpmw> fenn you are running FC4!
[20:13:37] <fenn> no
[20:13:45] <fenn> what?
[20:13:51] <fenn> * fenn hides
[20:14:10] <SWPadnos> hmmm - I got the same problem last night, I think
[20:14:21] <SWPadnos> it was a differnt problem after upgrading
[20:14:28] <SWPadnos> different, even
[20:14:41] <SWPadnos> Jymmm, have you tried urethane-based paints?
[20:15:10] <Jymmm> SWPadnos: no, does she think it'll work?
[20:15:15] <SWPadnos> no, he does ;)
[20:15:25] <fenn> bpmw: i'm not running straight FC4 but rather FC2 (or was it 3?) with a ton of modifications and upgraded packages
[20:15:42] <SWPadnos> I talked to a friend about it today, and he gave me a bunch of brand names that I don't remember ;)
[20:15:46] <Jymmm> SWPadnos: Hmmm, ok. Actually never heard of urithane paint, will have to look around for it.
[20:15:55] <SWPadnos> but non-water-based was thing one
[20:16:06] <SWPadnos> there are epoxies that are also good, if you keep them thin ehough
[20:16:24] <SWPadnos> you may be able to use a urethane wax as a sealer, then paint over it
[20:16:28] <Jymmm> SWPadnos: eeeeew on the epoxy. Do yo rememebr any of the brands at all?
[20:16:57] <bpmw> fenn, Great I'm gonna try FC4 tonight. Can't seem to get BDI-4.38 to install even. Grub problem. Thanks for the info.
[20:17:07] <SWPadnos> hmm - AC(something)
[20:17:17] <fenn> bpmw: ubuntu is what a lot of people are using
[20:17:24] <SWPadnos> I can email him again, and get it in writing
[20:17:34] <fenn> bpmw: there are debs, so installing emc is like 3 commands
[20:17:37] <Jymmm> SWPadnos cool
[20:17:47] <SWPadnos> bpmw, ubuntu is probably the way to go, if you want easy updates
[20:18:25] <bpmw> Sound good, I'll look for it! Thanks guys!!
[20:18:31] <fenn> bpmw: i had to patch/compile a custom kernel
[20:19:15] <bpmw> Ooh, I dont know if I can handle that.
[20:19:49] <SWPadnos> that was for FC4, not Ubuntu
[20:20:40] <SWPadnos> http://www.ubuntu.com/download
[20:21:04] <alex_joni> bpmw: http://timeguy.com/cradek/emc/ubuntu
[20:21:04] <bpmw> SWPadnos, Thanks I'll get right on it.
[20:21:23] <SWPadnos> heh. start now, especially if you have dial-up ;)
[20:21:48] <fenn> there's also puppy/coolcnc
[20:21:56] <bpmw> LOL , I'm at work right now, BROADBAND baby!
[20:22:09] <gene> Does anyone recall the syntax for something like:#6 - [40 COS * #4] ??
[20:22:17] <fenn> it's a livecd that's only 50MB
[20:22:19] <gene> Does anyone recall the syntax for something like:#6 = [40 COS * #4] ??
[20:22:37] <SWPadnos> you wnat the cosine of #4, multiplied by 40?
[20:22:41] <alex_joni> fenn: cvs commit: [20:22:21] waiting for fenn's lock in /cvsroot/emc/emc2/bin
[20:22:42] <SWPadnos> want
[20:22:47] <alex_joni> :(
[20:22:49] <bpmw> fenn, I tried it last night. Didn't like it much.
[20:22:57] <fenn> cos[#4]
[20:23:49] <gene> No, I want the cosine of 40 * #4, which in this case is the desired radius of the cut
[20:23:54] <SWPadnos> cool. just snagged an operator panel extension cable for my VFD for $8.12 shipped :)
[20:24:11] <SWPadnos> ok, so cos[40 * #4], using fenn's syntax
[20:24:50] <Jymmm> http://www1.chapman.edu/~jipsen/mathml/asciimathcalculator.html
[20:24:59] <fenn> parentheses are [] because ()'s are used for comments
[20:25:06] <fenn> and cosine is a function
[20:25:11] <gene> on my ti-36, wrong answer
[20:25:35] <fenn> ti-36!
[20:25:45] <SWPadnos> is that RPN?
[20:25:52] <gene> in other wors 40cos=.766044443
[20:26:08] <gene> and that * 1.6=
[20:26:11] <SWPadnos> wait, are you trying for a radius, or an endpoint?
[20:26:20] <fenn> cosine is a function
[20:26:21] <gene> 1.22567
[20:26:32] <fenn> cos(40) * 1.6
[20:26:46] <gene> radius stated as an endpoint
[20:26:59] <SWPadnos> ok, endpoint of an arc of some radius
[20:27:17] <SWPadnos> so [#4 * cos[40]]
[20:27:21] <fenn> * fenn hides
[20:27:39] <SWPadnos> and of course [#4 * sin[#4]] for Y
[20:27:43] <SWPadnos> oops
[20:27:49] <SWPadnos> and of course [#4 * sin[40]] for Y
[20:28:18] <gene> ok that looks right, lemme try it
[20:29:02] <fenn> jymmm talk to mbot
[20:29:18] <bpmw> Ok, Download started, talk to you guys later! Thanks again.
[20:29:22] <Jymmm> fenn ?
[20:29:27] <SWPadnos> see ya bpmw
[20:29:34] <fenn> /msg mbot % help
[20:30:17] <Jymmm> i didnt even know we had a bot in here
[20:30:23] <fenn> its not in this channel
[20:30:35] <Jymmm> ah
[20:30:39] <cradek> is g-code trig in degrees?
[20:30:48] <SWPadnos> it looks it from the examples in the docs
[20:31:09] <fenn> it should be.. entering data in radians could be interesting
[20:31:53] <SWPadnos> yeah - most machinistw ould wonder about circles that repeat every 6 or so degrees
[20:31:57] <SWPadnos> machinists
[20:32:01] <SWPadnos> would
[20:33:57] <gene> How does emc2 count lines when there are a lot of () comment lines?
[20:34:02] <Jymmm> lol gawd I hate junk mail..
[20:34:34] <alex_joni> gene: hard
[20:34:40] <alex_joni> ;-)
[20:35:15] <gene> I use spamassassin, gets 99% of the 5% that is spam here, hard count? I just comnmented line 14 and get the same no digits error as before
[20:35:33] <gene> line 14 is "m101 p#6 q#6
[20:35:37] <gene> line 14 is "m101 p#6 q#6"
[20:35:52] <fenn> gene please dont duplicate lines like that, it drives me nuts
[20:35:57] <Jymmm> signed up for a new account to place an order. For the first name I use: company_name_ordering_from + SMO. SMO == Sold Me Out so when I get crap from other places I'll know who to blame even though I did NOT check the box that says "Would you like stuff from other places"
[20:36:10] <gene> Correcting thb4 missing quote. sorry
[20:36:27] <gene> s/thb4/the
[20:36:29] <Jymmm> fenn that's a very short drive
[20:36:54] <gene> I've been lost on it for 71 years :)
[20:37:10] <fenn> Jymmm: haha
[20:37:14] <Jymmm> =)
[20:37:54] <jepler> gene: If you're talking about the line numbers that axis reports when it is creating the preview plot, the number often refers to the last preceeding line where a "canonical function" was called. This is a line that "does something", like a motion.
[20:37:54] <fenn> i have a steering wheel on my zipper
[20:38:02] <SWPadnos> that's good to know
[20:38:37] <Jymmm> fenn I bet the wifey appreciates that
[20:39:12] <gene> Anyway, line 13 is #6 = [#4 * COS[ 40 ]], and line 15 is a direct #7 = line
[20:39:39] <SWPadnos> and you get an error there?
[20:39:50] <gene> hang on huys, gotta scan something for the missus
[20:39:55] <gene> yup
[20:40:26] <SWPadnos> I wonder how you look at var values?
[20:40:34] <SWPadnos> can msg echo them?
[20:41:19] <cradek> M101 #4
[20:41:21] <jepler> SWPadnos: You can use M101 to print two values at a time. That's what gene's "line 14" is doing.
[20:41:30] <jepler> though I don't know why he's sending #6 twice
[20:41:38] <SWPadnos> oh right - I didn't really look at those
[20:41:48] <gene> cause their aint any dopcs on that thing!!!!!
[20:41:50] <SWPadnos> that was probably also a typ
[20:41:54] <SWPadnos> typo
[20:42:07] <gene> s/dopcs/docs
[20:43:09] <cradek> gcode programming makes me think of intercal
[20:44:12] <jepler> gcode programming's not quite that bad. It's much easier to generate gcode with a real programming language than it is to generate intercal.
[20:44:23] <cradek> true
[20:44:48] <cradek> (I've never written an intercal program, just snickered at it)
[20:45:07] <Jymmm> * Jymmm lol @ cradek
[20:49:21] <cradek> jmkasunich: uh-oh, don't let jepler see you
[20:53:06] <jmkasunich> why?
[20:53:35] <cradek> he's working on the hal config for his servo-controlled etch-a-sketch
[20:53:57] <jmkasunich> and he wants help?
[20:54:00] <SWPadnos> and looking for a PWM HAL component
[20:54:28] <fenn> cant you just use stepgen?
[20:54:28] <jmkasunich> freqgen with step type 1 is about as close as we can get
[20:54:35] <fenn> yeah freqgen even
[20:54:45] <jmkasunich> thats what I did
[20:55:14] <jmkasunich> true PWM is hard to do with an interrupt rate of 20 or 50 or even 100KHz
[20:55:37] <jmkasunich> if you want to do 10KHz PWM with 1% resolution you need a 1MHz clock
[20:55:50] <gene> Ok, me back
[20:55:59] <SWPadnos> well, you can do DDS-like PWM, which is considerably better
[20:56:06] <SWPadnos> for low granularity clocks
[20:56:23] <jmkasunich> thats basically what freqgen mode 1 is
[20:56:26] <SWPadnos> yep
[20:56:54] <SWPadnos> there was a bug in the maxfreq setting code, which jepler fixed
[20:57:05] <jepler> I still think it's wrong
[20:57:16] <jmkasunich> I saw the commit, couldn't review the code... I think it was right in the first place, but...
[20:57:18] <jepler> for type 0 the maxfreq should be 2/period, and for type 1 it should be 1/period ..
[20:57:36] <jmkasunich> thats what it is
[20:57:37] <jepler> but with my change it's now .5/period .. but at least I can get a 100% duty cycle
[20:58:01] <SWPadnos> there wasn't a special case fortype 1
[20:58:14] <SWPadnos> so it got the same maxfreq as type 0
[20:58:33] <jmkasunich> I thought it got the same freq as everything but type 0
[20:58:57] <jepler> Maybe I misread the source code
[20:58:59] <fenn> * fenn goes to bed
[20:59:08] <jepler> but before the change I made, I couldn't get >50% duty
[20:59:43] <jmkasunich> really strange, I could swear it worked for me
[20:59:47] <jmkasunich> looking at code now
[21:01:06] <gene> Near line 12, equalk sign missing in parameter setting, heres lines 10-13
[21:01:41] <gene> #5 = 0.0000
[21:01:43] <gene> (end of x travel in G2 mode)
[21:01:45] <gene> (#6 = 1.22567)
[21:01:47] <gene> #6 = [ #4 * COS [ 40 ] ]
[21:02:07] <jmkasunich> jepler: lets talk about freqgen in -devel
[21:02:11] <gene> line 12 is commented, like line 11
[21:02:21] <jepler> jmkasunich: Will you be around later? I'm at work right now, and can't run emc
[21:02:28] <jmkasunich> probably
[21:02:33] <jepler> jmkasunich: OK, I'll check back later
[21:02:39] <jepler> jmkasunich: thanks for offering! I really appreciate it.
[21:04:08] <jepler> I'm toying with the idea of creating a HTML table quick reference to gcode. I'd like to get opinions on it: http://emergent.unpy.net/index.cgi-files/sandbox/gcode.html
[21:04:50] <cradek> clicking on the gcode should go to the right part of the kramer doc
[21:04:56] <jepler> Yeah, I envision that
[21:05:04] <cradek> the terse format looks useful
[21:07:08] <jmkasunich> nice
[21:08:26] <jmkasunich> cradek: ubuntu question: one of the available updates is a kernel (not the RTAI one, the stock one) If I allow the udate to be installed, will it become my default kernel? I know when you install a new kernel deb it becomes the default, but dunno about updates.
[21:08:32] <gene> The front page looks nice
[21:08:40] <cradek> it'll do what you want
[21:08:44] <jmkasunich> good
[21:10:01] <jmkasunich> jepler: I assume the other headings will have lines under them like Motion and Plane Selection do?
[21:10:16] <jmkasunich> so it will wind up being a couple screens long
[21:10:34] <jepler> jmkasunich: yes
[21:11:28] <jmkasunich> looks good - short enough that if you're just trying to figure out which code does what you don't have to read a book, but with links to details
[21:12:16] <gene> I give up, whats wrong with this line: #6 = [ #4 * [ COS [ 40 ] ] ]
[21:12:35] <Jymmm> Just fyi... looks likes shit with CSS disabled =)
[21:12:42] <gene> where #4 is 1.6000
[21:12:51] <cradek> gene: that line looks fine to me
[21:13:08] <cradek> gene: I wonder if you're getting an incorrect error message (has been known to happen)
[21:13:21] <gene> ok next line :m101 p=#4 q=#6
[21:13:35] <cradek> I think = is not valid
[21:13:50] <bill2or3> I just sketched out a rough idea for a DIY linear bearing, does this look workable?
[21:13:52] <bill2or3> http://scoot.net/gallery/bbs/rail-idea.jpg
[21:13:56] <gene> and that exact syntax does work in other other routnes I've written/hacked :)
[21:14:02] <bill2or3> that's the end view, there would be 2 sets per block.
[21:15:01] <bill2or3> with all the triangle mounts being adjustable.
[21:15:08] <jmkasunich> bill2or3: would only be suitable for very clean environments, or if you equip it with some kind of wipers to keep dirt out
[21:15:47] <LawrenceG> bill2or3: a 3 bearing version would be easier to align
[21:15:55] <bill2or3> I could probablly seal the sides and ends with plexiglass and felt wipers..
[21:16:02] <Jymmm> jepler: Ah, no closign tags... </td></tr> that's probably why
[21:16:34] <bill2or3> good point. although mounting them every 120 degrees would be a bit harder.
[21:16:52] <LawrenceG> bill2or3: 2 on top, one on bottom to adjustable to preload bearings
[21:17:01] <jmkasunich> depending on the orientation of the load, you don't need 120 degrees
[21:17:09] <bill2or3> so at the upper-corners, and the center of the bottom?
[21:17:14] <jmkasunich> depends on the load
[21:17:19] <jepler> Jymmm: My HTML reference says the end tags for TR, TH and TD are optional.
[21:17:20] <bill2or3> you think it'd be ok to have them spaced unevenly?
[21:17:36] <bill2or3> they're not you need </tr>'s
[21:17:42] <bill2or3> or it will nest the rows.
[21:17:46] <Jymmm> jepler: In html 4.01 trans it is, just tosses the browser into quirks mode is all.
[21:17:47] <jmkasunich> for example, if the rod is fixed and the moving bearing supports a heavy table, keep the two top bearings (rigid) and put the adjustable one at bottom center
[21:18:04] <bill2or3> jmkasunich, yeah, I understand.
[21:18:08] <LawrenceG> bill2or3: even 12oclock, 3oclock and 6 oclock if used with opposing bearing block on other side of table
[21:18:39] <LawrenceG> or simpler at 2oclock and 5 oclock
[21:18:57] <jmkasunich> what kind of machine?
[21:19:09] <bill2or3> gantry mill.
[21:19:24] <bill2or3> with Y and Z on the gantry
[21:19:44] <jmkasunich> mill as in metal and high precision, not router as in wood, large workspace, fast?
[21:20:05] <LawrenceG> you need big rails ( or supported ones) to keep the deflections down on long axis
[21:20:28] <bill2or3> small tabletop mill for light metals and plastic.
[21:20:28] <Jymmm> 120 deg allows you to use supported rail/bar
[21:21:15] <jmkasunich> any particular reason you want to use rolling bearings instead of sliding (bronze bushings on steel rod, or dovetail ways, or similer)?
[21:21:31] <bill2or3> not really.
[21:21:54] <bill2or3> I have no machining background, I'm really just figuring this all out as I go.
[21:21:55] <Jymmm> jmkasunich : same as me originally... being cheap =) (more than likely)
[21:22:01] <bill2or3> so if there's a better way, let me know.
[21:22:06] <bill2or3> :-)
[21:22:12] <jmkasunich> bronze bushings are cheaper than bearings
[21:22:24] <jmkasunich> of course a lot depends on what you already have
[21:22:28] <bill2or3> I'd just use abec-5 skate bearings, I have a bunch
[21:22:36] <SWPadnos> but for a riding carriage, bearings should wear better, no?
[21:22:41] <Jymmm> bill2or3 what's the longest travel you plan on having again?
[21:22:44] <bill2or3> and I have a line on some free abec-7 bearings, if I need them
[21:22:52] <jmkasunich> I take it you don't already have a mill _or_ lathe?
[21:22:53] <bill2or3> jymm, that axis would be like 18"
[21:23:06] <bill2or3> jmk, I have a micro-mill and a mini lathe.
[21:23:11] <jmkasunich> SWP: don't be so sure about wear
[21:23:13] <bill2or3> both manually operated.
[21:23:29] <bill2or3> so I can make small stuff.
[21:23:41] <jmkasunich> hardened steel outer race of a ball bearing running on a hard or soft steel rod is a point contact, very high contact pressure
[21:23:46] <gene> Ok, got that working. But whyinhell does it appear that an m101 line thats wrong gets parsed anyway when its commentd out?
[21:23:46] <Jymmm> bill2or3 have you consider any bowing (drooping) with unsupported rail?
[21:23:55] <jmkasunich> and very unhappy about metal chips or dirt
[21:24:14] <bill2or3> I have some 1" stainless steel round, I'd use two of them, I'm hoping that will be strong enough not to bow.
[21:24:15] <jmkasunich> bronze bushings on rod is a surface contact, low contact pressure, oil film
[21:24:20] <cradek> gene: submit bug reports if you find interpreter bugs
[21:24:22] <jmkasunich> sweeps away most dirt and chips
[21:24:36] <Jymmm> bill2or3 ah, ok.
[21:24:42] <jmkasunich> bill: how big is the rod?
[21:24:49] <bill2or3> I'm worried that bronze bushings would get play in them as they wear down.
[21:24:55] <gene> Watch stainless for gauling...
[21:24:57] <jmkasunich> duh. I didn't see the 1"
[21:24:58] <bill2or3> jmk, just a hair under an inch
[21:25:04] <bill2or3> pretty beefy stuff.
[21:25:23] <bill2or3> I got it at a local freight salvage place.
[21:25:39] <jmkasunich> what is the finish?
[21:25:48] <jmkasunich> mill finish isn't all that smooth or round
[21:26:58] <bill2or3> I dont know the terms, but it's pretty smooth and shiny.
[21:27:05] <bill2or3> not like extruded aluminum.
[21:27:48] <bill2or3> not surface-ground, but still smooth.
[21:28:20] <jmkasunich> I'm afraid you'll be unpleasantly surprised by how that works with the bearings
[21:28:47] <bill2or3> how so? there will be enough variation that keeping all the bearings touching wont happen?
[21:28:48] <jmkasunich> think about it - the OD of the bearing is a cylinder about 1" dia, as is the rod
[21:28:55] <jmkasunich> they're at right angles to each other
[21:28:56] <bill2or3> ok.
[21:29:04] <bill2or3> yeah, tiny tiny contact area.
[21:29:13] <jmkasunich> lots of pressure at that tiny area
[21:29:19] <jmkasunich> the bearing is hardened steel
[21:29:27] <jmkasunich> the rod, if stainless, isn't likely all that hard
[21:29:37] <jmkasunich> you might wind up with a track mark in the rod
[21:29:41] <bill2or3> I think maybe I'm putting too much emphasis on keeping the friction low.
[21:30:00] <bill2or3> since the bearing-friction is tiny compared to the cutting forces anyway.
[21:30:11] <jmkasunich> also, if metal chips get in there, they'll either jam it up, or be driven into the surface of the rod by the high contact pressure
[21:30:42] <jmkasunich> thats why all but the biggest, fastest machines use metal-on-metal ways with oil, instead of rolling elements
[21:31:05] <jmkasunich> routers are different - they are much faster, so the friction becomes a problem
[21:31:09] <bill2or3> my other idea was 2 rollers out of delrin, with a Vee profile.
[21:32:07] <bill2or3> maybe that'd be better.
[21:32:31] <jmkasunich> one of the more challenging things with any two-rail design is getting the rails parallel
[21:32:52] <jmkasunich> if you have 0.001" of play in your bearings, the rods have to be parallel to better than that to avoid binding
[21:33:20] <jmkasunich> unless you specifically design it to be tolerant of that
[21:33:24] <bill2or3> yeah, I'd make the rod-mounts adjustable.
[21:33:25] <jmkasunich> for instance, if you are using rollers
[21:33:48] <jmkasunich> on rod #1, have rollers at 2, 6 and 10 o-clock
[21:34:01] <jmkasunich> on rod #2, have rollers at 12 and 6 o-clock
[21:34:45] <bill2or3> so I'm spreading the loading evenly thru the 360deg ?
[21:35:21] <jmkasunich> so rod #1 handles vertical and side loads, rod #2 handles vertical loads only and tolerates some side-to-side misallignment
[21:35:27] <bill2or3> I see.
[21:35:33] <jmkasunich> same principle as lathes with one V way and one flat way
[21:36:00] <bill2or3> I'd never thought of that. thanks for pointing it out.
[21:36:46] <jmkasunich> actually for rod 1 you could do 12, 3, 6, 9 o-clock, would be easier to build
[21:36:53] <jmkasunich> rod 2 would have 12 and 6 only
[21:37:16] <bill2or3> yeah, 4 points would be a lot easier than 3
[21:37:18] <jmkasunich> make the 3 and 6 bearings adjustable to fit the rod
[21:37:37] <bill2or3> since I dont have an angle-vise, or any way to hold work at odd angles.
[21:38:01] <jmkasunich> do you have a micrometer that reads to better than 0.001"?
[21:38:17] <bill2or3> no
[21:38:18] <jmkasunich> before you decide to use the rods you have, measure them for taper and roundness
[21:38:24] <bill2or3> I have a dti though
[21:38:38] <jmkasunich> that won't help here
[21:38:44] <bill2or3> ok.
[21:38:57] <jmkasunich> actually the DTI would be good for testing for straightness
[21:39:03] <bill2or3> you're talking about a "C" shaped micrometer, not regular calipers, right?
[21:39:16] <jmkasunich> yes
[21:39:22] <bill2or3> * bill2or3 thinks.
[21:39:45] <jmkasunich> for straightness, rest the ends of the rods in v-blocks, put the dti in the middle, and rotate slowly
[21:39:45] <bill2or3> actually, I may have some in my "things that belonged to my grandfather" collection.
[21:39:50] <bill2or3> :-)
[21:40:02] <bill2or3> I'll have to check when I get home.
[21:40:11] <jmkasunich> the v-blocks don't have to be fancy
[21:40:40] <bill2or3> ok.
[21:40:46] <jmkasunich> for roundness, measure the diameter of the rods at several angles
[21:41:03] <bill2or3> I understand that part.
[21:41:09] <jmkasunich> 12 o-clock, 3 o-clock, etc
[21:41:27] <jmkasunich> and for taper, measure at both ends and several places in the the middle
[21:41:42] <bill2or3> got it.
[21:41:53] <jmkasunich> your machine will only be as accurate as the rods, so its good to know what you have before you get to far
[21:42:30] <Jymmm> what about using a piece of string to check the rods for bowing too
[21:42:49] <jmkasunich> ?!?
[21:43:03] <jmkasunich> we're looking for bows of 0.001" here
[21:43:54] <jmkasunich> bill2or3: good rods aren't too expensive
[21:44:19] <jmkasunich> 1" diameter 1045 steel TGP (turned, ground and polished) is about $10 for 18" from metal express
[21:45:31] <jmkasunich> 1045 hard chromed is about $12

[22:02:25] <jmkasunich> jepler: running an old freqgen here (before your change) and I have no trouble getting 100%
[22:02:46] <jmkasunich> contact me when you get home, somethings probably wrong with your hal config, not the freqgen module
[22:02:56] <jepler> jmkasunich: alright
[22:03:57] <jmkasunich> g-code table - very nice
[22:04:04] <jmkasunich> hi ray
[22:06:04] <bill2or3> $10 isn't bad at all.
[22:06:16] <bill2or3> could I use some 1" drill-rod, or is it not hardened?
[22:06:40] <rayh> Hi John
[22:07:01] <jmkasunich> bill: drill rod is usually more expensive
[22:07:10] <rayh> jmkasunich, you still on the road?
[22:07:15] <jmkasunich> neither drill rod nor the 1045 are hardned
[22:07:20] <jmkasunich> no ray, just got back
[22:07:30] <jmkasunich> (3 hours early, I was able to catch an early flight)
[22:07:30] <rayh> Great. Good to be home.
[22:07:33] <jmkasunich> yep
[22:08:09] <jmkasunich> bill: the hard chrome 1045 is probalby the best wearing, that chrome coating is harder than hardened steel
[22:08:27] <bill2or3> thanks for the advice jmk.
[22:08:27] <CIA-8> 03jmkasunich * 10emc2/src/ (Makefile hal/utils/meter.c): Made some minor improvements to halmeter and added a man page for it
[22:08:41] <bill2or3> is metalexpress pretty good, price-wise?
[22:08:51] <rayh> Ho-wah! That's good.
[22:08:58] <jmkasunich> crap, forgot the cvs add
[22:08:58] <bill2or3> I have a Metals Supermarket locally, which is where I get most of my stock.
[22:09:11] <jmkasunich> they probaby have similar pricing
[22:09:18] <rayh> btw we need to .gz these and have the make install put them in the right place.
[22:09:23] <bill2or3> plus no shipping. :-)
[22:09:54] <rayh> The new gnome desktop help has a search function.
[22:10:03] <CIA-8> 03jmkasunich * 10emc2/docs/man/man1/halmeter.1: Made some minor improvements to halmeter and added a man page for it
[22:10:42] <jmkasunich> I think the .gz part is optional, if an uncompressed version exists man will use it
[22:10:55] <jmkasunich> and I think the make install does install them in the right place
[22:11:18] <cradek> it does, and they get in the deb properly
[22:11:21] <jmkasunich> I have cradek's deb installed here, and it has working man page for halcmd
[22:11:49] <rayh> Yep you're right.

[22:17:21] <jmkasunich> quick reference for g-code
[22:17:44] <jmkasunich> it will eventually have links to the appropriate section in the cramer document for more detail
[22:19:49] <rayh> * rayh looking
[22:25:02] <rayh> Problem is that the kramer doc is dated.
[22:25:29] <cradek> it's still good for many things, but I agree some things need to be updated
[22:25:39] <rayh> And I believe that editing it requires a commercial package.
[22:25:45] <cradek> too bad we don't have "source" for it
[22:25:53] <cradek> yikes.
[22:26:09] <jmkasunich> its pdf?
[22:26:20] <cradek> it's some kind of auto-generated html
[22:26:31] <cradek> so we could edit the html I suppose, but that's not the "source" format
[22:27:11] <rayh> One small nit G54 -> G59.3 are modal or at least act like modal.
[22:27:36] <gene> Nother silly Q: How do I adjust the size of the 'cutter' dot in asix?
[22:27:37] <rayh> I like the layout a lot.
[22:27:54] <cradek> gene: you mean the cone?
[22:28:11] <rayh> Someday we should add the o word
[22:28:15] <gene> Yeah cept I'm looking at the xy presentation
[22:28:57] <cradek> rayh: g54 etc are explicitly modal group 12
[22:29:22] <cradek> gene: you can't, it's auto-sized based on the program extents. you can turn it off if it's in the way (edit menu?)
[22:29:38] <gene> Also, maybe I need to slow PERIOD down, but axis locks for minutes at a time if I change gfx views
[22:29:58] <cradek> gene: you have something terribly wrong if it does that, it changes instantly
[22:30:12] <rayh> Okay. On the emergent page they are listed as non modal
[22:30:33] <cradek> rayh: yep, bug
[22:31:05] <gene> Humm, needs a green point dot when turned off so you can still see where its at.
[22:32:25] <rayh> cradek, very small one ;
[22:32:33] <gene> yippers
[22:33:46] <jepler> I probably got some of the URLs wrong, haven't checked them yet .. but updated again: http://emergent.unpy.net/index.cgi-files/sandbox/gcode.html
[22:34:48] <cradek> jepler: did you see the bug report (g54 etc are modal)
[22:35:28] <jepler> cradek: nope, missed it
[22:35:52] <cradek> http://www.isd.mel.nist.gov/personnel/kramer/pubs/RS274NGC_3.web/RS274NGC_33a.html#1001063
[22:35:59] <cradek> this shows that they are modal group 12
[22:37:01] <cradek> this looks great, you should link to it from the front page of the wiki
[22:38:42] <cradek> jmkasunich: a nit about halmeter: the button should be Apply, not ACCEPT
[22:40:22] <jepler> updated again: fixed g54, added one line for all O- words
[22:41:10] <cradek> jmkasunich: (and if the buttons really yell at you like the man page says, that should be fixed too (OK, Apply, Cancel))

[22:42:35] <skunkworks> cradek - ran my oword spiro program on the actual machine. I don't think it could do the math quick enough on the 450mhz or something. where is the link to the torcher test program?
[22:43:00] <cradek> what do you mean? what problem do you see?
[22:43:03] <skunkworks> it was pretty jerky - not smooth at all.
[22:43:12] <cradek> tort.ngc is in cvs somewhere
[22:43:21] <skunkworks> ah - I will look.
