[00:00:11] <wb9mjn> He said he got 2.7 turns , instead of 1 ...
[00:00:40] <rcsu> ok, the point is, you see it as a hardware prob, its a new install so i wont disagree at all
[00:00:40] <wb9mjn> Not good to get ahead of things...best to do the measurement first ...
[00:01:20] <rcsu> i dont have the chance to do the exact measure :(
[00:01:29] <wb9mjn> But, a loose ground could generate ground noise and add extra pulses, from AC even, if its a CMOS input....when we get to it, he might try 10 K ohm resistors to improve noise...
[00:01:30] <rcsu> unless you can tell me how
[00:02:07] <rcsu> wb9mjn: not that, ive learned that !
[00:02:16] <wb9mjn> I used a caliper against a fixed portion of the machine...then pushed out the caliper head till it touched the table...
[00:02:44] <rcsu> whats your caliper ?
[00:02:45] <wb9mjn> before and after the movement, record the difference...do it again, in the same direction....
[00:02:59] <alex_joni> rcsu: check google ;)
[00:03:08] <alex_joni> not sure how it's called in german
[00:03:09] <wb9mjn> Should get within .03 mm ...
[00:03:32] <wb9mjn> caliper is a measuring stick, with dial indicator ...
[00:03:50] <alex_joni> rcsu: you could even set the moving speed very low, to get about 1 pulse/second
[00:03:52] <wb9mjn> Starrett, Mitutoyu, Brown and Sharpe ...etc ...
[00:04:11] <alex_joni> and actually look at the stepper
[00:04:11] <alex_joni> and see what's happening
[00:04:28] <wb9mjn> If you see varations more than about .5 mm, and random, you probably have hardware problem...
[00:04:36] <wb9mjn> electronic hardware problem...
[00:05:06] <rcsu> ok, Schieblehre
[00:05:09] <wb9mjn> make that .2 mm ...
[00:05:27] <wb9mjn> writing teacher ?
[00:05:29] <alex_joni> genau
[00:05:40] <rcsu> alex_joni: ok, 1 Pulse/s
[00:05:46] <alex_joni> schreiben is writing
[00:05:52] <alex_joni> schieben is pushing
[00:05:56] <wb9mjn> oops..
[00:06:02] <alex_joni> rcsu: might be also a bit more, but you get the idea
[00:06:18] <wb9mjn> well, last time I had German was 30 years ago, hi..
[00:06:40] <alex_joni> 1mm/min = 400 pulses/min => 6.667 pulses / second
[00:07:10] <rcsu> ehm ?
[00:07:15] <alex_joni> so you need about 0.14 mm/min for 1 pulse/second (if INPUT_SCALE is 400)
[00:08:03] <alex_joni> rcsu: the alternative would be to start only HAL
[00:08:18] <alex_joni> and set up a stepgen with the exact frequency you want
[00:08:22] <rcsu> alex_joni: thats wrong, 400 pulses/mm
[00:08:29] <alex_joni> and use that to drive the motor with 1 pulse / second
[00:08:55] <rcsu> ill try that 1 pulse /s
[00:09:06] <alex_joni> rcsu: if you travel with 1mm/min, and you have 1mm=400 pulses, then you get 400 pulses/min
[00:09:37] <rcsu> thats MAX_VELOCITY = 0.0025, right ?
[00:09:58] <alex_joni> you can enter in MDI: G1X1F0.0025
[00:10:13] <rcsu> too late :)
[00:10:15] <alex_joni> but 0.0025 is a bit low
[00:10:23] <alex_joni> you enter speeds / minute iirc (or was it per second?)
[00:12:20] <wb9mjn> In EMC 1 its /second in the .ini and /min in the G code...
[00:14:00] <wb9mjn> F100 would be good in Metric...
[00:14:34] <wb9mjn> equivalent to 1.666666 in the .ini ...
[00:14:51] <wb9mjn> Or F60, for one turn per second...
[00:14:58] <alex_joni> wb9mjn: he has the ini in metric
[00:15:10] <alex_joni> don't confuse him even more :D
[00:15:20] <alex_joni> F60 should mean = 60 mm/min
[00:15:22] <wb9mjn> That s how I set up my MF-70...I am talking metric...
[00:15:27] <alex_joni> 1 mm / sec
[00:15:31] <wb9mjn> Right....
[00:15:39] <alex_joni> but he wants 1 pulse / second, which is 400 times slower
[00:15:47] <wb9mjn> Oh...sorry...
[00:16:06] <alex_joni> wb9mjn: no problem, thanks for jumping in
[00:16:19] <wb9mjn> F.15 ..
[00:16:28] <wb9mjn> 60/400 ...
[00:16:33] <alex_joni> <alex_joni> so you need about 0.14 mm/min
[00:16:47] <alex_joni> wb9mjn: rounding errors :D
[00:16:54] <wb9mjn> hi ..
[00:19:07] <wb9mjn> Should see some good resonant behavior on the motor axis if you have a knob on it, at that speed...bonk...bonk ....bonk....
[00:20:10] <wb9mjn> If it wiggles, rather than just steps, that s another issue that may force you to a microstepping drive...
[00:20:12] <rcsu> hum, i counted 39 steps for ~90 degrees
[00:20:41] <wb9mjn> What was the X , 1 ? G1X1F.15 ?
[00:22:05] <alex_joni> 40 steps ~90 degrees -> 160 steps / turn
[00:22:53] <alex_joni> with your set up 400 steps / turn -> 400/160 = 2.5 (just about right with what you said earlier)
[00:23:12] <alex_joni> so my guess is that the motor is not 200 steps / turn
[00:23:17] <wb9mjn> Are you sure you have 200 step steppers ?
[00:23:35] <alex_joni> or maybe the drive is not half stepping, but it is multiplying the pulses (unlikely)
[00:23:47] <wb9mjn> 78 step steppers were common at one time...
[00:23:50] <rcsu> no, they only say microangle steppers
[00:24:03] <rcsu> but 788 != 160
[00:24:14] <rcsu> 76 != 160
[00:24:15] <alex_joni> 78 * 2 = 156
[00:24:23] <wb9mjn> So were 39 ...for the big 8 inch floppies...
[00:24:27] <alex_joni> pretty close I'd say :D
[00:24:37] <wb9mjn> 39/2 times 4 =78 ...
[00:24:40] <alex_joni> if you have a 78 steps/turn motor, and half stepping
[00:24:53] <wb9mjn> Yep...
[00:25:14] <alex_joni> 400/156=2.56 (even closer)
[00:25:23] <wb9mjn> micro-angle might be how accurate they are ...hot how high a resolution...
[00:26:14] <wb9mjn> 78*2 =156, instead of 400 ?
[00:26:26] <wb9mjn> Try that ?
[00:26:55] <rcsu> thats very close to what i have observerd !
[00:27:05] <rcsu> thanks a lot
[00:27:46] <alex_joni> rcsu: not the software after all :D
[00:28:09] <rcsu> yes, the BD between my ears :)
[00:28:11] <rayh> I see that the stepper configs don't start here.
[00:28:13] <wb9mjn> good idea to do the 1 pps thing...
[00:28:38] <alex_joni> wb9mjn: yes, too bad it's that hard :D
[00:28:50] <alex_joni> more & more I start to like the feature request a user had
[00:29:00] <alex_joni> to have a wizard helping on the setup
[00:29:06] <alex_joni> for exactly stuff like this
[00:29:16] <alex_joni> screen says: push the limit X+
[00:29:22] <alex_joni> user pushes->ok
[00:29:34] <alex_joni> measure distance traveled on X
[00:29:40] <alex_joni> emc commands 1 mm, user measures
[00:29:49] <alex_joni> emc commands .5m, user measures
[00:29:52] <alex_joni> etc.
[00:30:06] <rcsu> like a wizard
[00:30:20] <alex_joni> yeap
[00:30:25] <alex_joni> for newbies
[00:30:33] <wb9mjn> Your steppers are probably surplus from double or quad density 8 inch floppy drives...
[00:30:34] <alex_joni> advanced users probably won't use it..
[00:30:39] <wb9mjn> Hi...
[00:31:12] <alex_joni> I remember playing with 8 inch floppies as a child
[00:31:27] <wb9mjn> Well, not so much for newbies, unless they are converting a Sherline to EMC 2 ...
[00:31:44] <alex_joni> some 15-20 years ago :D
[00:31:53] <alex_joni> hi ?
[00:32:01] <alex_joni> you keep saying that..
[00:32:08] <rayh> I've still got a toaster full of 8" floppies on the first unix box I ran.
[00:32:08] <wb9mjn> Hi, is ham radio slang for ha ha ha ha...
[00:32:12] <rcsu> but thats a basic test, to get the resolution of your stepper / revolver
[00:32:22] <wb9mjn> Can t get out of the habbit...
[00:32:54] <rcsu> what must be done do do such a druid ?
[00:33:08] <rcsu> to do
[00:33:49] <alex_joni> hrmm.. for that we might need a thingy to convert the ini
[00:34:14] <rcsu> no, thats for advanced users
[00:34:29] <rcsu> a druid is for nebees (like me)
[00:34:37] <wb9mjn> Need something right to convert in the first place, for it to be useful for newbies...
[00:35:02] <wb9mjn> For newbies, need more like a GUI configuration utility...
[00:35:27] <alex_joni> yes. like I described above..
[00:35:52] <wb9mjn> Ask questions, (menus) with fixed selections, and fields for variable entry...
[00:35:58] <wb9mjn> Oops...missed it ...
[00:35:59] <alex_joni> it's in the wiki (under Features something..)
[00:36:34] <wb9mjn> Yep...a wizard...
[00:36:47] <wb9mjn> not a conversion utility ...
[00:36:51] <alex_joni> with a pointy hat :D
[00:37:20] <wb9mjn> and a beard (rayh ?) ...
[00:37:33] <alex_joni> wb9mjn: behave :P
[00:37:55] <rcsu> the prob at all is the faulty hw and OS setup
[00:38:28] <rcsu> its hard to guide that with an wizard
[00:39:50] <rayh> When I proposed a wizard I seem to remember someone saying "if they don't know what they are doing with the ini, they ought not to be trying."
[00:39:55] <alex_joni> yes, and one that can take care of all the problems is unlikely to be built
[00:40:06] <alex_joni> rayh: :P
[00:40:24] <alex_joni> we might want to change some views regarding 'customers'
[00:40:39] <rayh> Good idea.
[00:40:48] <alex_joni> but maybe an online knowledgebase is ok (like the wiki)
[00:41:01] <wb9mjn> Well....we had the same sentiments with NOS..(Network Operating System)....but now Windows Network stuff is all by menus, and some wizzard stuff...
[00:41:34] <alex_joni> a wizard done by 1-2 people has no chance to get all the cases are usually found, but a cooperative approach like the wiki might
[00:41:38] <wb9mjn> But, then , a mess up there could screw half a state packet radio network....
[00:41:38] <rcsu> thats not the leage your are playing :)
[00:42:00] <K4ts_> K4ts_ is now known as k4ts
[00:42:01] <wb9mjn> not crash a machine...
[00:42:08] <alex_joni> rcsu: no, we are a bit above that
[00:42:20] <rcsu> * rcsu grins
[00:42:35] <alex_joni> I'd say emc is far more stable than doze :P
[00:42:40] <alex_joni> and I run both..
[00:43:13] <rayh> what is doze? ;)
[00:43:15] <wb9mjn> NOS ran on DOS, and was a TCPIP stack for the early ham networks...it was OK reliability wise...
[00:43:20] <alex_joni> windoze
[00:43:35] <wb9mjn> It was closely modelled after UNIX IP stack, before Linux existed...
[00:43:42] <rcsu> its not a q of stability nor of usability, its just a q of simpliness
[00:43:48] <alex_joni> wb9mjn: was there a time before? :D
[00:43:59] <alex_joni> rcsu: different users look for different things
[00:44:02] <wb9mjn> Maybe not for you ?
[00:44:03] <Jacky^> woooooo
[00:44:20] <alex_joni> wb9mjn: sure there was.. I had a nice Spectrum in the beginning :)
[00:44:28] <rcsu> * rcsu is a Linux user !
[00:44:35] <alex_joni> rcsu: some want an easy to use desktop machine
[00:44:49] <alex_joni> others want a very robust industrial-grade controller
[00:44:57] <alex_joni> which is OK to be hard to set up
[00:44:57] <Jacky^> after 10000 windows wizard connection sharing is working !
[00:45:04] <Jacky^> damn wizard :/
[00:45:16] <alex_joni> Jacky^: you're just about right in the conversation
[00:45:18] <alex_joni> ROFL
[00:45:19] <rcsu> but if you want success, you need the stupidness setup of windoze
[00:45:24] <Jacky^> :D
[00:45:48] <alex_joni> rcsu: depends how you define success
[00:45:56] <alex_joni> remember it's all GPL
[00:46:13] <wb9mjn> The Debian Linux on a 700 MHz plus machine is not too shabby...
[00:46:15] <rcsu> set up this in a klick :)))
[00:46:16] <alex_joni> maybe one developer won't get his kicks by how many users use EMC
[00:46:32] <wb9mjn> Not a big fan of Red Hat though...
[00:46:37] <alex_joni> he wants a software that works for him, and only for him.. which is ok
[00:47:10] <rcsu> oh alex_joni thats not a success
[00:47:31] <skunkworks> speaking of internet - just found out today that we can get fre long distance, answering service, and 1.5mbs down (was 768kbs) for a dollar less than we are paying now. (phone company/dsl) I think we finally have competition in this area.
[00:47:46] <rcsu> a good software works for other setups too
[00:48:03] <alex_joni> rcsu: again, that might be your definition..
[00:48:14] <rcsu> alex_joni: sure
[00:48:19] <alex_joni> but it's a free software project
[00:48:34] <alex_joni> so everyone is entitled to work towards his goal
[00:48:52] <rcsu> alex_joni: but you cant get broad success until you say your own thing is it
[00:49:25] <alex_joni> I might not care about broad success
[00:49:33] <alex_joni> let's take a scenario
[00:49:38] <alex_joni> I want to sell plasma tables
[00:49:49] <alex_joni> and I want to use emc as a control
[00:49:56] <rcsu> depricated
[00:50:00] <alex_joni> my goal is to make it industrial, ready, etc
[00:50:09] <rcsu> depricated
[00:50:22] <alex_joni> depricated?
[00:50:27] <alex_joni> how so?
[00:50:39] <rcsu> its far bejond done
[00:50:50] <alex_joni> not really..
[00:50:55] <alex_joni> there are still some issues
[00:50:58] <wb9mjn> For 2 D stuff its probably OK, unless your doing high end routers like les...
[00:51:03] <alex_joni> but that's not important
[00:51:04] <rcsu> yes, plasma is out
[00:51:08] <wb9mjn> For 3D, the TP needs work....
[00:51:22] <alex_joni> wb9mjn: for any xD the TP needs work
[00:51:28] <wb9mjn> Or at least that s the concensus...
[00:51:45] <alex_joni> if I want to do plasma cutting I need high speeds on thin sheets
[00:51:45] <rcsu> think that way towards LCD displays
[00:51:50] <alex_joni> like 1-2 m/sec
[00:52:14] <rcsu> BenQ is nearly to that timings
[00:52:19] <alex_joni> rcsu:that's another thing.. I might want a touch screen GUI for emc
[00:52:20] <rcsu> on LCDs
[00:52:25] <wb9mjn> If you do not maintain speed the same everywhere along the trajectory, does that widen your kerf ?
[00:52:32] <alex_joni> yes
[00:52:48] <alex_joni> and it affects the quality of the cut
[00:53:08] <wb9mjn> So, for a router with a fixed bit with, its more forgiving, unless you have hardware that can go megafeet/min , like les's and thermood...
[00:53:10] <alex_joni> you have one optimal cutting speed (depending on material, current, plasma gas, etc.)
[00:53:11] <k4ts> hello
[00:53:30] <alex_joni> wb9mjn: well plasma is usually m/min cutting speed
[00:53:36] <alex_joni> not that fast
[00:53:37] <wb9mjn> fixed bit width...
[00:53:45] <alex_joni> but a laser.. might be faster
[00:54:05] <wb9mjn> thermwood...that is...
[00:54:06] <alex_joni> seen some nice 12kW lasers lately.. they go through steel like through butter
[00:54:17] <rcsu> no, a laser in this context is really slow
[00:54:32] <alex_joni> not a 12kW laser on .5 mm sheets
[00:54:45] <alex_joni> cutting away at 2-3 m/sec
[00:55:15] <rcsu> you need the speed to 'ablenken' that power
[00:55:19] <alex_joni> you'd be amazed how they work these days :)
[00:56:03] <rcsu> and to controll the lighning
[00:57:09] <rcsu> thanks for your help !
[00:57:13] <rcsu> cu
[00:57:15] <alex_joni> darn connection again
[00:57:20] <alex_joni> later rcsu
[00:57:26] <wb9mjn> your welcome....
[00:59:06] <Jacky^> :-)
[01:09:36] <alex_joni> I'm off to bed
[01:09:38] <alex_joni> night all
[01:09:55] <Jacky^> night alex
[01:10:11] <k4ts> night
[01:42:50] <Jacky^> G night all
[05:32:04] <Jymmm> whats a comment in gcode?
[05:59:27] <Jymmm> Jymmm is now known as Red70sShow
[05:59:28] <Red70sShow> Red70sShow is now known as Jymmm
[12:39:03] <Jacky^> morning :)
[12:46:21] <alex_joni> morning skunkworks
[12:49:21] <skunkworks> morning - whats up?
[12:49:41] <alex_joni> nothing :)
[12:50:16] <Jacky^> morning
[12:50:35] <skunkworks> that might be a good thing. ;)
[12:50:44] <alex_joni> indeed
[12:51:34] <Jacky^> * Jacky^ upgranding his laptop 40.3kB/s 3h32m15s
[12:51:37] <alex_joni> breakfast time
[12:51:45] <Jacky^> bleahh slow dsl here
[12:51:55] <alex_joni> Jacky^: I gaveabout 1.5 kB over here :D
[12:51:58] <alex_joni> have
[12:52:09] <alex_joni> IF thereception is
[12:52:10] <skunkworks> really - what time is it there - it would be considerd breakfast time here.
[12:52:17] <alex_joni> 14:52
[12:52:19] <alex_joni> :P
[12:52:21] <Jacky^> :-)
[12:52:24] <skunkworks> funny
[12:52:34] <alex_joni> yeah.. but I was up till 3 am
[12:52:39] <alex_joni> later guys
[12:52:40] <skunkworks> 6:50
[12:52:43] <skunkworks> take it easy
[12:52:51] <Jacky^> later alex
[12:54:09] <skunkworks> jacky - my wife just found out we can get 1.5mbs down + answering servic + free long distance for a dollar less than we have been paying for our phone service. (used to be 768kbs)
[12:54:29] <skunkworks> must be competition around here now
[12:54:42] <Jacky^> skunkworks, good .. :P
[12:55:19] <Jacky^> here are atlaking about voip since 2003 ..
[12:55:32] <Jacky^> but it wont to take the fly
[12:55:48] <Jacky^> too much business conflict
[12:56:13] <skunkworks> I bet - it has been a round. vontage is one of the popular companies
[12:56:25] <skunkworks> around here
[12:56:37] <Jacky^> k4ts is payng E. 45/mounth for dsl 1024/256 ..
[12:56:46] <Jacky^> here
[12:57:03] <skunkworks> is that just dsl or dsl + phone service?
[12:57:16] <Jacky^> with no phone line
[12:57:18] <Jacky^> just dsl line
[12:57:31] <Jacky^> no voice
[12:57:46] <skunkworks> wow - well I really don't know what we are paying. (shouldn't talk) ;)
[12:58:10] <Jacky^> same dsl of this in France cost about 15 E.
[12:58:23] <Jacky^> here45
[12:58:33] <Jacky^> same company
[12:58:46] <Jacky^> heres Telecom Italia, there Telecom France
[12:58:58] <skunkworks> wow - I know it isn't 15 dollars here - maybe 30 or so.
[12:59:08] <Jacky^> yeah ..
[12:59:34] <skunkworks> hell people are paying 25 dollars for just dialup aol lol
[12:59:49] <Jacky^> :/
[13:00:03] <Jacky^> it may depend on speed too ..
[13:00:11] <skunkworks> I live out in the boonies and ran directway satellite for a few years before dsl (2 way satellite internet)
[13:00:56] <Jacky^> uhm.. my cousin live in a mountains zone, there is no dsl cable line there
[13:01:17] <Jacky^> he tried with the satelite kit but hes disappointed
[13:01:33] <Jacky^> a bit faster of 56 k line , he sayd .. :/
[13:02:57] <skunkworks> yeh - ping time is around 1 second on a good day (damn speed of light)
[13:03:32] <skunkworks> but I could download at a peak of around 4mbs upload was lucky to be 50kbs
[13:03:45] <Jacky^> for download maybe is ok .. but for upload is bad
[13:04:18] <skunkworks> then there was snow/heavy rain outages. Oh and the 168mb download cap per 8 hours ;)
[13:04:27] <skunkworks> but it was better than dialup
[13:04:38] <Jacky^> sure
[13:04:58] <skunkworks> plus the high techness of it :)
[13:05:08] <Jacky^> hehe
[13:05:11] <skunkworks> (transmitting to a sattelite - cool)
[13:05:38] <Jacky^> are you able to do that ?
[13:05:41] <Jacky^> :)
[13:06:11] <Jacky^> my cousin was using phone line 56k for upload ..
[13:06:16] <skunkworks> not any more. ;) dsl is so much more stable.
[13:06:33] <skunkworks> yep - that was an option also here. although they where trying to phase it out
[13:07:08] <skunkworks> they called that 1 way satellite
[13:09:05] <Jacky^> the issue we have here is for upload, too slow
[13:09:31] <Jacky^> we just have offers with poor upload band
[13:09:54] <Jacky^> I hope antitrust will move a bit in the next year ..
[13:10:06] <skunkworks> I have 256kbs - have not tested it though
[13:10:13] <Jacky^> theyre breaking the progress, really :(
[13:10:21] <skunkworks> both here at work and at home
[13:10:25] <Jacky^> yes, on the paper ..
[13:10:31] <skunkworks> right
[13:10:42] <Jacky^> not guaranteed
[13:10:44] <skunkworks> like I said - never done a speed test
[13:11:01] <Jacky^> I do it every mounth
[13:11:37] <Jacky^> im having trouble to use skype too
[13:11:38] <skunkworks> do you have the option of cable internet?
[13:11:44] <Jacky^> for the same reason :(
[13:12:22] <Jacky^> theres some isp selling dsl via optical fiber
[13:12:32] <Jacky^> but youve no public IP
[13:12:38] <Jacky^> are in a big lan ..
[13:13:05] <Jacky^> I think theyre going to copy US style
[13:13:16] <Jacky^> all in one cable, dsl, tv, etc..
[13:13:24] <skunkworks> wow - interesting - that is how I was on direcway satellite -
[13:13:35] <skunkworks> no public ip
[13:13:41] <Jacky^> public IP and a lot of features are available as options
[13:13:42] <skunkworks> sucked
[13:13:52] <Jacky^> :)
[13:14:26] <skunkworks> we have static here at work which is really nice.
[13:15:05] <Jacky^> yeah, this where Im now (k4ts) is static too
[13:15:24] <Jacky^> but she pay about 4 E,/mounth for that
[13:15:36] <skunkworks> right - it is extra here also
[13:15:59] <skunkworks> and I think they still block port 80 outgoing so no web hosting
[13:16:40] <Jacky^> uhm, no, we dont have any block
[13:17:00] <skunkworks> (might be a business thing) I don't know
[13:17:23] <Jacky^> yeah, probably it is
[13:17:39] <Jacky^> launch time ..
[13:17:53] <skunkworks> ;) eat well
[13:18:17] <skunkworks> I assume you ment lunch - not launch (like a rocket)
[13:39:29] <jepler> morning folks
[13:44:09] <skunkworks> morning
[13:44:36] <skunkworks> anything new?
[13:44:48] <Jacky^> connection losted :(
[13:45:06] <Jacky^> Jacky^ is now known as Jacky^launch
[13:46:26] <Jacky^launch> Jacky^launch is now known as Jacky^lunch
[14:03:06] <jepler> skunkworks: not much new here
[14:05:40] <skunkworks> thats ok ;)
[14:23:52] <Jacky^lunch> Jacky^lunch is now known as Jacky^
[14:24:54] <Jacky^> hi jepler , alex_joni
[14:25:08] <alex_joni> hello
[14:28:29] <Jacky^> rain & rain
[14:29:05] <Jacky^> I wonder when we'll made some nice photo here around :(
[14:29:49] <Jacky^> planning to pass 31 night in a restaurant ..
[14:30:18] <Jacky^> are 100 E./people too much ?
[14:30:21] <Jacky^> :D
[14:30:37] <Jacky^> dinner, dance, etc ..
[14:31:30] <Jacky^> it seem 80% of peoples will stay at home here , 31 evening
[14:34:26] <alex_joni> * alex_joni goes to build one of these : http://wading-in.net/Remote.html
[14:36:17] <Jacky^> ahahha
[14:36:23] <Jacky^> cool ]:)
[14:37:03] <Jacky^> damn hackers :P
[14:37:11] <alex_joni> lol
[14:37:20] <Jacky^> :)
[14:38:31] <Jacky^> anyway great camera ;)
[14:39:44] <Jacky^> im tryng to learn how to manually improve performance of my camera ..
[14:39:58] <Jacky^> im just using it in auto-mode
[14:40:14] <Jacky^> not good at all , with this bad weather
[14:40:33] <alex_joni> heh, bad weather is nice too for photographs
[14:40:36] <Jacky^> pics are dark , too dark
[14:40:40] <alex_joni> but it's a bit harder
[14:41:05] <Jacky^> im tryng to do a lot of pics using different settings
[14:41:38] <Jacky^> then compare the results..
[14:42:02] <alex_joni> digital?
[14:42:15] <Jacky^> yes, sony camera
[14:42:26] <alex_joni> then it should be fairly easy
[14:42:34] <Jacky^> it have 7-8 auto mode , and manual settings
[14:43:07] <Jacky^> yeah, it should be
[14:43:44] <Jacky^> but im pretty sure that to get good photos its an art
[14:43:47] <Jacky^> :(
[14:43:55] <alex_joni> what are you shooting?
[14:44:42] <Jacky^> Id like to find best settings for dark ambients
[14:45:01] <Jacky^> like, hall, with neon light
[14:45:16] <Jacky^> and panoramics with bad wheater
[14:45:22] <Jacky^> weather
[14:45:57] <alex_joni> use long exposures for both
[14:46:07] <alex_joni> but that means probably a tripod
[14:46:23] <Jacky^> yeah, tryng to get it as best I can ..
[14:46:44] <alex_joni> smaller apertures, and longer exposures
[14:46:49] <Jacky^> it also have autofocus
[14:47:01] <alex_joni> that's ok
[14:47:09] <Jacky^> but in some case manual focus setting should be better, I suppose
[14:47:23] <alex_joni> very few cases
[14:47:28] <Jacky^> playng around all settings :)
[14:47:38] <alex_joni> ok.. I'm gone.. will be back later
[14:47:47] <Jacky^> bye
[14:47:54] <alex_joni> shoot in Av if your camera has such a program
[14:48:10] <Jacky^> yes,:)
[14:48:17] <alex_joni> there you can set aperture, and it selects exposure
[14:48:31] <alex_joni> check google for tutorials :P
[14:48:33] <Jacky^> good..
[14:48:34] <alex_joni> bye
[14:48:39] <Jacky^> bye
[18:47:39] <Jymmm> What's a comment in gcode?

[19:10:34] <Jymmm> thanks cradek
[19:21:41] <Jacky^> hello
[19:24:55] <Jacky^> hi Jymmm
[19:25:39] <Jacky^> I solved the issue about to share connection ..
[19:26:39] <Jymmm> bought an ethernet router for $20 ?
[19:27:02] <Jacky^> nope, just using the windows wizard ...
[19:27:26] <Jymmm> cool
[19:27:33] <Jacky^> after 3-4 wizard pass, I got it working ..
[19:28:02] <Jacky^> I was thinking iptables was available ..:(
[19:28:32] <Jacky^> I just know 3 command to share connection !
[19:31:36] <Jacky^> I had to run and follow 3-4 times the wizard
[19:37:00] <Jacky^> This evening Pizza with fruits of seaaaaaaaaaaa
[19:37:02] <Jacky^> :D
[19:41:39] <Jacky^> * Jacky^ preparing gastric juices for the battle !
[20:00:16] <alex_joni> evening
[20:00:52] <Jymmm> hi alex_joni
[20:01:07] <alex_joni> what's up Jymmm?
[20:01:14] <Jymmm> broken tooth
[20:01:19] <alex_joni> ouch
[20:01:46] <Jymmm> nah, I broke the tooth 20+ years agoa nd it was bonded, just needs to be rebonded
[20:01:55] <alex_joni> I see
[20:02:01] <Jymmm> luckily enough
[20:02:08] <Jymmm> knock on wood
[20:02:12] <alex_joni> heh
[20:03:29] <Jymmm> so, found a dentist that can rebond it for $90, one quoted me $500
[20:04:15] <alex_joni> http://wading-in.net/Remote.html
[20:04:19] <Jymmm> just got off the phone with a oral surgeon that I saw 5yrs ago to get copies of xrays so I dont have to pay for them again.
[20:04:23] <alex_joni> just made one of these
[20:04:27] <alex_joni> works great
[20:06:39] <Jymmm> $20 and wireless --> http://www.digitalcamera.it/catalog/images/ML-L3nikon.jpg
[20:06:42] <Jymmm> =)
[20:07:30] <Jymmm> 1/8" thick
[20:08:19] <Jymmm> alex_joni_: 1/8" thick, $20 and wireless --> http://www.digitalcamera.it/catalog/images/ML-L3nikon.jpg
[20:08:54] <alex_joni_> yes, there is one for the canon aswell
[20:09:32] <Jymmm> well, for $20 you just can't beat it.
[20:09:50] <Jymmm> Though, a corded RF remote would be nice too.
[20:09:57] <Jymmm> corder/RF
[20:11:04] <jepler> I don't know if the D50/D70 support a corded remote
[20:11:15] <alex_joni_> hi jeff
[20:11:31] <Jymmm> Heh, I can remote control the camera via USB, but me neither =)
[20:11:56] <alex_joni_> what's a corded remote?
[20:12:27] <Jymmm> alex_joni: you plug in a box to the camera, and the box is a Rx.
[20:12:41] <alex_joni_> ahhh I see
[20:12:44] <Jymmm> oh a corded remote is what you built
[20:12:55] <Jymmm> 20 ft cord
[20:13:07] <Jymmm> remote == away from the camera itself
[20:13:34] <Jymmm> cord/cable/wire etc
[20:13:40] <alex_joni_> right.. the rebels have USB, corded and irda for that
[20:14:16] <Jymmm> I never actually LOOKED if my camera has a corded remote jack, but who knows.
[20:14:31] <Jymmm> It's doens't have a plunger, that I do know.
[20:14:42] <Jymmm> but it has a shitload of jacks on it
[20:15:54] <Jymmm> actually the SB800 has the shitload of jacks.... was even able to trigger the strobe I just bought
[20:16:26] <Jymmm> which I thought was cool, but not TTL =(
[20:28:33] <SWP_Away> cheapskates - buy a set of PocketWizards, increase my income... http://www.pocketwizard.com
[20:28:39] <alex_joni_> alex_joni_ is now known as alex_joni
[20:30:42] <Jymmm> SWP_Away: No need, my camera has built in remote control TTL too
[20:30:53] <SWP_Away> which one?
[20:31:08] <Jymmm> SWP_Away Nikon D70.... supports up to 4 speedlights.
[20:31:28] <SWP_Away> yep - not that they'll work corerctly in fluorescent light
[20:31:38] <Jymmm> SWP_Away They do
[20:31:39] <SWP_Away> correctly
[20:31:58] <SWP_Away> though you can't use the remote triggering anyway - the D70 has no remote port, right?
[20:32:21] <Jymmm> I have a IR remote for it, link to pic scrollup
[20:32:52] <SWP_Away> I've seen that - I was wondering about the standard 10-pin connector, like on the F5 and D1/D2
[20:33:01] <SWP_Away> and F100
[20:33:15] <Jymmm> dont know, dont have one
[20:33:27] <SWP_Away> I mean the D70
[20:33:55] <SWP_Away> I think I checked that one for use in the camera array, and it didn't have the remote port
[20:34:20] <SWP_Away> in any case, when I refer to "my old company" - it's the company that manufactures the PocketWizards
[20:35:25] <Jymmm> much much is a pair?
[20:35:34] <SWP_Away> yes - much much :)
[20:35:43] <Jymmm> how much is a pair?
[20:35:57] <SWP_Away> the Plus is around $300, and the Max is around $500 (per pair)
[20:36:20] <SWP_Away> though they work at much longer ranges, and have loads of features that the in-strobe remotes don't
[20:36:26] <SWP_Away> and they're mssing TTL at the moment
[20:36:29] <SWP_Away> missing
[20:36:29] <Jymmm> they lie http://www.pocketwizard.com/HTML/pwnikond.asp
[20:36:44] <Jymmm> well that's kinda/sorta useless
[20:36:50] <SWP_Away> they lie?
[20:36:57] <Jymmm> no D70 support =)
[20:37:23] <SWP_Away> they explicitly list the D1, D1x, and D1X
[20:37:27] <SWP_Away> diH, I mean
[20:37:28] <Jymmm> at least my SB800/600 have ttl support.
[20:37:34] <SWP_Away> D1H - there, dammit!
[20:37:37] <Jymmm> "D Series"
[20:37:59] <SWP_Away> they should have said "expensive D-Series"
[20:38:07] <Jymmm> that works
[20:38:16] <SWP_Away> though the D50, D70, D100, and D2 didn't exist when the product was introduced
[20:38:28] <Jymmm> (c) 2005 at the BOP
[20:38:48] <dmess> hello all.... trying out a new xmas laptop from bdi install onto the web in 5 mins
[20:38:49] <SWP_Away> I suspect that's due to the header changing or something
[20:38:50] <Jymmm> anyhow...
[20:39:22] <Jymmm> So far, I'm happy with the internal IR remote flash
[20:39:52] <SWP_Away> the flash isn't IR, I think - it actually pulses the flash tube to send commands to the remotes
[20:39:57] <Jymmm> no $25 cables to buy, no cbales to trip over
[20:39:58] <dmess> new camera??? Jymmm
[20:40:50] <Jymmm> dmess: Not new, alex_joni is though
[20:41:20] <Jymmm> SWP_Away: There is some IR on the SB800,
[20:41:34] <Jymmm> as there are groups channels and TTL too.
[20:42:15] <SWP_Away> right - I just think they use the flash tube for signalling, they may be detecting the IR emissions from the tube (I may be thinking of how the Metz strobes work)
[20:42:28] <SWP_Away> it's been a while since I was actively involved in that business
[20:43:08] <dmess> i got a nice new 2.99" reflective telescope with a max of 675 x magnification from my wife who likes me alot
[20:44:25] <jepler> dmess: oh neat
[20:45:18] <alex_joni> nice
[20:45:49] <dmess> we had 14 nights of clear nights from dec 1 to dec 23... been cocked in clouds since...
[20:46:03] <dmess> socked... sorry
[20:46:19] <alex_joni> lol
[20:46:49] <dmess> ive been looking at bird nests on the mall 2 KM away... just for kicks
[20:47:49] <dmess> i COULD see a boob thru a window but if it jiggled id lose it...
[20:47:51] <Jymmm> alex_joni I thought you got a 300mm lens?
[20:47:59] <alex_joni> yes
[20:48:08] <alex_joni> actually a zoom, 75-300
[20:48:10] <dmess> what cam???
[20:48:11] <Jymmm> alex_joni: must be grainy
[20:48:21] <alex_joni> Jymmm: not at all
[20:48:28] <Jymmm> alex_joni show me
[20:48:32] <dmess> thats a nice lens...
[20:48:38] <alex_joni> it's a bit slow (4.5 but works great)
[20:48:45] <fenn> anyone know the length of a standard cigarette?
[20:48:47] <Jymmm> I have a 18-70, then a 70-300
[20:48:52] <Jymmm> 80mm
[20:48:59] <fenn> thanks
[20:49:15] <Jymmm> fenn Marlboro 100's == 100mm
[20:49:17] <alex_joni> dmess:it's the entry level 75-300, there is a 75-300 with IS and USM
[20:49:18] <dmess> 80 mm id quite different
[20:49:35] <alex_joni> I have 18-55 and 75-300
[20:49:51] <alex_joni> and a few on my film SLR's
[20:49:54] <alex_joni> :)
[20:50:37] <dmess> hmmm the new pentax slr IS SWEET...

[20:51:16] <Jymmm> someone I know just got the pentax, almost equiv to the D70
[20:51:46] <alex_joni> dmess: I like my canon 350D :P
[20:52:31] <dmess> i'll never fight the camera fight ... again... ; )===~~~~
[20:52:38] <alex_joni> :P
[20:52:41] <alex_joni> right
[20:53:05] <dmess> especially with the digi's avail these days
[20:53:31] <dmess> it used to be the man... now its the machine
[20:56:46] <SWP_Away> OK - just ordered a new scope - I hope I can afford to pay for it
[20:57:05] <dmess> o-scope???
[20:57:08] <SWP_Away> yep
[20:57:13] <SWP_Away> MSO6104A
[20:57:17] <SWP_Away> http://www.home.agilent.com/USeng/nav/-536898394.536905493/pd.html
[20:58:00] <SWP_Away> or here: http://agilentdirect.tm.agilent.com/teleweb/comp/ComparisonController.do?NAV_ID=-536898394.0.00&processComparison_params=state%253dprocessComparison&processComparison_encoding=u&button_processComparison=Compare&cmd=button&compId316=yes&compId317=yes&compId318=yes&compId319=yes
[20:58:04] <dmess> i seen one in a cash converters for $245 ...yesterday..i left it to come down some more
[20:58:21] <SWP_Away> huh? what's that in english? :)
[20:58:36] <cradek> pawn shop?
[20:58:54] <cradek> MegaZoom III!
[20:58:55] <cradek> hahaha
[20:59:04] <SWP_Away> yeah - gotta love the marketing types
[20:59:18] <SWP_Away> it's a great feature though
[20:59:48] <cradek> sounds like a fun video game
[20:59:54] <dmess> pawn shop... 245 canuck buck===175 yankee buks
[21:00:13] <SWP_Away> well - the old scopes in the series two (or three) before had Centipede and Tetris in them
[21:00:18] <cradek> $175 is a cheap scope
[21:00:22] <cradek> if it's any good
[21:00:34] <SWP_Away> well - if you buy that scope for $175, I'll pay you $500 for it ;)
[21:00:39] <SWP_Away> assuming it works
[21:00:39] <Jymmm> ...and doesn't weight 85 lbs
[21:01:07] <SWP_Away> the 6000 series is really light
[21:01:31] <SWP_Away> they're smaller than the previous ones (I have a 54622D now), and that includes a compartment to store probes and stuff
[21:01:39] <alex_joni_> alex_joni_ is now known as alex_joni
[21:01:41] <dmess> ill go get spec and the likes first ...if it of use to some one... its here..
[21:02:40] <SWP_Away> there's one of these on eBay right now for $10k - I may get that one instead, if teh guy tells me what options it has, and I have the opportunity to check the serial number for "irregularities"
[21:02:48] <cradek> I'll stick with my antique Tek 466
[21:02:53] <alex_joni> hi chris
[21:02:56] <cradek> hello
[21:02:59] <SWP_Away> much less expensive that way
[21:04:11] <SWP_Away> christ - they're selling those for up to $1k
[21:04:43] <cradek> what mine?
[21:04:47] <SWP_Away> yep
[21:04:50] <cradek> doesn't surprise me
[21:05:06] <SWP_Away> I just did a quick search, and see prices from $250 or so up to $1000
[21:05:15] <dmess> shiite im goonn go grab that one
[21:05:23] <SWP_Away> it surprises me a bit, considering that it's an analog storage scope (right?)
[21:05:29] <cradek> yes
[21:05:37] <cradek> I really like it
[21:05:45] <SWP_Away> we used those in the military, 20 years ago ;)
[21:05:49] <SWP_Away> and I think they were old then
[21:05:58] <dmess> yes...
[21:06:13] <cradek> and they're all still working, maybe I have the one you used to use
[21:06:37] <SWP_Away> if it has a tag saying something like "AN/USM 575", then it might be ;)
[21:06:45] <dmess> STILL WORKING... operant words
[21:07:09] <SWP_Away> but not quite fast enough, or with enough channels, for newer (faster) designs
[21:07:24] <cradek> well I'm a hobbyist
[21:07:30] <SWP_Away> in that case, it's plenty
[21:24:59] <Jymmm> use guys ever use a keyhole bit?
[21:28:43] <Jymmm> got quiet in here
[21:31:57] <fenn> that's "t-slot cutter" to you, mister
[21:32:49] <Jymmm> fenn "Yes, Dear"

[21:34:19] <fenn> well, there's a lot of repetetive stuff, but it looks like it does what you want it to
[21:35:03] <Jymmm> Well, something fubared last night when I ran it is why I asked.
[21:35:06] <fenn> you are cutting the slot first with an endmill right?
[21:35:17] <skunkworks> ;)
[21:35:18] <Jymmm> um, no. (wood)
[21:35:22] <skunkworks> ouch
[21:35:46] <Jymmm> it's that the purposes of the upper cutters?
[21:35:48] <fenn> cut the slot first, then use the slot cutter
[21:36:00] <fenn> it's not really meant for cutting
[21:36:22] <Jymmm> ok, what am I missing here?
[21:36:50] <Jymmm> there really are upper cutters on it.
[21:37:09] <fenn> i believe you
[21:38:10] <fenn> when doing it on metal one always cuts the slot first
[21:38:25] <fenn> it might work in wood without the slot, since you can crush the chips inside the hole
[21:38:33] <skunkworks> to get the correct surface speed/chip load for the major diameter - the small diemeter will have too much chip load.
[21:39:48] <Jymmm> Yeah, it did scream like a banchee last night.
[21:39:58] <skunkworks> do you cut a 2 inch slot in wood at two diffent hights? what happened
[21:40:20] <Jymmm> no, one height.
[21:40:25] <skunkworks> ah
[21:40:36] <Jymmm> does my code show two different heights?
[21:40:56] <Jymmm> * Jymmm first hand written gcode btw
[21:41:04] <skunkworks> no - I lost it after the last z.2
[21:41:46] <skunkworks> what did it do that was wrong?
[21:41:50] <Jymmm> z.2 iirc is "safe height"
[21:42:10] <Jymmm> well, it WAS .4 instead of .375
[21:42:45] <Jymmm> so that ripped the piece off the table for one
[21:43:08] <dmess> its sinometer yb4328 20 MHz 0-scope
[21:43:09] <Jymmm> it was way too deep, than it should have been, and I did measure it too.
[21:43:34] <Jymmm> skunkworks so I think my code is fubared somewhere
[21:44:01] <dmess> what shape you trying to machine>>
[21:44:05] <fenn> the code is fine, at least in theory
[21:44:13] <fenn> feeds might be wrong etc
[21:44:14] <skunkworks> emc2
[21:44:18] <skunkworks> ?
[21:44:25] <Jymmm> dmess this shape ---------------------- =)
[21:44:42] <Jymmm> skunkworks no 1
[21:44:44] <Jymmm> ,
[21:44:51] <dmess> how BAD can your code be...???
[21:45:03] <Jymmm> dmess scroll up to find out =)
[21:45:05] <skunkworks> did you do a g92 in mdi to set the hight you wanted for z then run the program?
[21:45:27] <fenn> ew g92==icky
[21:45:30] <fenn> use g54
[21:45:34] <skunkworks> fenn - right
[21:45:41] <Jymmm> what you see is what I did
[21:45:45] <skunkworks> that is why I was asking - does some funky stuff
[21:45:50] <dmess> guys from my perspective g92 is unnecessary... and the cause of alot of issues
[21:45:51] <skunkworks> ah
[21:45:52] <fenn> z=0 was the top of the blank right?
[21:46:08] <Jymmm> correct
[21:46:22] <skunkworks> how thick was the t-slot cutter?
[21:46:35] <Jymmm> 3/8"
[21:46:40] <Jymmm> into mdf
[21:46:46] <fenn> how was it held down?
[21:46:59] <Jymmm> edge clampped
[21:47:19] <dmess> how wide
[21:47:36] <skunkworks> wouldn't -.375 cut right at the surface then
[21:47:47] <Jymmm> when I look at the piece, it went at least .1" more than it should have (deep)
[21:47:57] <Jymmm> .375" wide,
[21:48:11] <dmess> it sucked the mdf UP that far my friend
[21:48:20] <fenn> i'm thinking the shaft was pushing on the un-cut mdf at the top of the cut
[21:48:54] <Jymmm> maybe not enough chip removal
[21:48:57] <dmess> the cutter needs ver fine plunges to avoid grabbing
[21:49:19] <dmess> when the chip builds up and adheres
[21:50:13] <fenn> dmess this is mdf, you aren't gonna have any chip buildup
[21:50:39] <Jymmm> fenn maybe no place for the chip to actually go... as still in the recessed slot
[21:50:47] <dmess> if you are more than 4:1from where you are clamping.. it will suck UP though
[21:51:00] <Jymmm> 4:1 ?
[21:51:09] <fenn> Jymmm: yeah you could try "pecking" like in a peck drill cycle
[21:51:15] <fenn> but moving sideways not up and down
[21:52:04] <Jymmm> hmmmm, never considered a keyhole to be so envolved =)
[21:52:24] <Jymmm> fenn I see what you're saying there, to clear out some of the chips
[21:53:04] <Jymmm> not the best pic, but this is what I sorta have... http://sherwoodcreationsinc.com/images/products/X-181.jpg
[21:54:22] <fenn> i dont think there will be enough relief on the upper cutters to allow easy cutting
[21:55:00] <fenn> so it pushes the piece to the side, then when it backs out it digs into the rear wall of the entry hole and pulls UP when the bit retracts
[21:55:24] <fenn> or something like that
[21:55:49] <Jymmm> fenn: ok, so endmill, then keyhole bit. Both using the same gcode above should do it?
[21:55:55] <fenn> yeah
[21:56:53] <fenn> the endmill should help with chip extraction too
[21:56:54] <Jymmm> Are keyhole bits meant to upcut the larger hole upon extraction? O---------------O
[21:57:01] <fenn> no
[21:57:29] <Jymmm> this one does have cutters where that would be this is why I ask
[21:57:42] <Jymmm> s/this/the case/
[21:58:05] <fenn> look at the relief on the top edge of the bit
[21:58:24] <fenn> if it's angled, go for it, but if it's a 90 degree angle it won't cut anything and will probably break something
[21:58:55] <Jymmm> * Jymmm grabs loop
[21:59:21] <Jymmm> It's the same angle on top as it is on the bottom.
[21:59:39] <Jymmm> /--------\
[21:59:47] <fenn> like a bowtie?
[21:59:55] <fenn> er, half a bowtie
[22:00:55] <fenn> well, only one way to find out
[22:01:22] <fenn> i'd be worried about chips clogging in the hole on the way up though
[22:01:28] <skunkworks> what is the hight of the slot that it is supposed to make?
[22:01:46] <Jymmm> fenn didn't think of that.
[22:02:00] <Jymmm> skunkworks depth?
[22:02:17] <Jymmm> from surface to max depth is .375"
[22:02:46] <skunkworks> right - but what is the dimention of the cutter? 3/8 by what thickness
[22:03:05] <fenn> jymmm try it on blue styrofoam or wax first to see what happens with the chips
[22:03:19] <fenn> if they melt, that means it won't work on mdf
[22:03:22] <Jymmm> skunkworks 3/8" x 3/8"
[22:03:49] <Jymmm> fenn an the old mel tthe shit out of shit test =)
[22:03:52] <Jymmm> melt
[22:04:15] <Jymmm> I like it =)
[22:04:25] <fenn> i just thought of it
[22:05:02] <Jymmm> Well, though it's a PITA, your endmill+tslot I think is KISS
[22:05:23] <fenn> well you gotta do a toolchange already, what's another toolchange
[22:05:34] <Jymmm> What about my feedrates ?
[22:05:39] <fenn> no idea
[22:05:52] <skunkworks> spindle speed?
[22:06:02] <Jymmm> skunkworks 8k to 25k
[22:06:36] <Jymmm> I went slower on them to do minimal damage to the finished piece
[22:06:45] <fenn> .375*2pi*rpm*feed/12 = sfm
[22:07:15] <skunkworks> so then what is a good sfm for mdf?
[22:07:23] <skunkworks> (I don't know)
[22:07:26] <fenn> er whoops that formula's wrong sorry
[22:07:50] <fenn> there's two factors, sfm and chipload
[22:08:14] <fenn> .375*2pi*rpm/12 = surface speed
[22:08:21] <fenn> in feet/min
[22:08:27] <Jymmm> in IPM ?
[22:08:31] <Jymmm> heh, was just asking that
[22:08:39] <fenn> that's a different concept than feed
[22:08:51] <fenn> it's the speed of the cutting blade relative to the workpiece
[22:09:17] <Jymmm> divide by 60
[22:10:09] <fenn> ipm/rev/number of teeth = chipload
[22:10:37] <fenn> ipm/(rev*teeth)
[22:10:54] <Jymmm> I really have to program that into my calculator sometime
[22:11:02] <ajoni> ajoni is now known as alex_joni
[22:11:15] <skunkworks> need one of the need slide calculaters - quick and easy
[22:11:22] <fenn> .006 to .010 seems to be the rule for mdf
[22:11:25] <fenn> chipload
[22:11:26] <Jymmm> HP 20s
[22:13:37] <Jymmm> OT... it's sad that HP only has 3 calculators anymore.
[22:13:45] <fenn> feed = 48 to 80 ipm at 8000 rpm, can you do that?
[22:16:44] <Jymmm> but not so slow that it'll friction char the piece
[22:17:19] <fenn> 80 ipm is a lot faster than i expected actually
[22:18:36] <Jymmm> fenn I can do 200 IPM under MS-DOS =)
[22:19:26] <fenn> i think steppers are a dumb idea
[22:20:31] <alex_joni> fenn: depends on the application
[22:20:40] <alex_joni> in some areas they are the best
[22:21:05] <fenn> well, not cnc milling machines
[22:21:48] <dmess> whow??
[22:21:57] <dmess> whom???
[22:22:03] <fenn> dmess: stepper motors
[22:22:39] <Jymmm> Yeah, and Mariss fucking with me about them =)
[22:22:42] <dmess> steppED
[22:22:54] <Jymmm> or his stepper drivers that is.
[22:24:04] <dmess> stepper drivers are fubared??
[22:24:31] <Jymmm> dmess JAS
[22:25:14] <Jymmm> it was a thread on the yahoo gecko groups when I asked MAriss if his drives prevent mid-band 100% or 99.999% of the time and he said 101% of the time.
[22:25:41] <dmess> as the dukes say... kill em all.....
[22:26:11] <fenn> i'm making a gun.. a revolver
[22:26:16] <fenn> it shoots cigarettes
[22:26:23] <Jymmm> lol
[22:26:35] <fenn> you stick the gun in your mouth and pull the trigger and it blasts a flaming cigarette into your mouth
[22:26:37] <dmess> giv'er
[22:26:46] <alex_joni> fenn: into your guts :D
[22:26:55] <alex_joni> through the stomach
[22:27:10] <fenn> relatively weak explosion, maybe 20 ml of air + 1 ml butane
[22:27:52] <dmess> at 20 L and 1 L we lookin for a fine BOOM
[22:28:44] <fenn> yeah but this is pointed at your face remember
[22:29:06] <fenn> i'll be surprised if it actually works
[22:30:20] <dmess> i wanna see before and after pics..
[22:33:31] <alex_joni> dmess: of his face?
[22:37:41] <dmess> i would think thats where the stuffs gonna happen... i figure
[22:38:05] <alex_joni> probably won't notice anything
[22:38:20] <alex_joni> *grin*
[23:07:20] <dmess> : )
[23:16:32] <dmess> i should get to try my new telescope tomorrow night...maybee... please.... ;(
[23:16:44] <alex_joni> heh, I have one too
[23:16:52] <alex_joni> but I guess I don't have time for it :)
[23:17:26] <dmess> make time for the cosmos cause it makes time for you
[23:18:37] <dmess> there is a messier marathon in february...
[23:19:01] <alex_joni> I'm not sure how to use it though, never made the time to figure it out :D
[23:20:11] <dmess> i see... my wife got me a nice 3 " reflector telescope for xmas.... i love that woman...
[23:20:38] <dmess> so i dont know how to use IT either yet...
[23:20:40] <alex_joni> I'm not even sure what kind mine is :D
[23:20:52] <alex_joni> I know it has a mirror inside
[23:21:02] <alex_joni> about 8-10 cm
[23:21:35] <dmess> sounds about the same..
[23:21:55] <alex_joni> * alex_joni hunts for a pic
[23:22:06] <dmess> big barrel that you look into the side of??
[23:23:17] <alex_joni> yup
[23:23:44] <dmess> is the image upside down??? or have you even noticed??
[23:23:52] <alex_joni> nope
[23:23:59] <alex_joni> didn't notice
[23:24:05] <alex_joni> I looked at the moon once
[23:24:11] <alex_joni> wasn't that thrilling :D
[23:24:16] <alex_joni> except it was very bright
[23:24:36] <dmess> LOL... mine needs a Barlow lens to rectify the image upright
[23:25:12] <dmess> and the MOON is way bright with any reflector scope yes
[23:26:15] <alex_joni> http://www.greiner-petter.de/assets/images/Telesk4.jpg
[23:26:18] <alex_joni> this one
[23:28:12] <dmess> mine has a 900mm focul lenthg as opposed to 700mm... all else looks the same
[23:29:11] <alex_joni> wonder if I could fit my camera and take some pictures with it
[23:29:30] <dmess> im planning on trying...
[23:29:58] <alex_joni> ok, let me know how it goes
[23:30:13] <alex_joni> also.. watch out for robin_sz, he seems to know a bit about teleskopes
[23:31:27] <dmess> i tried to view thru the cel the phone cam the other night... but i was tooo drunk... lol
[23:33:01] <alex_joni> lol
[23:34:22] <dmess> even with the 20mm lens its a far shot
[23:34:40] <alex_joni> how do you plan on fitting a camera to it?
[23:35:59] <dmess> i was thinking of a light web cam and a piggyback mount
[23:36:14] <alex_joni> how about a serious cam?
[23:37:18] <dmess> serious cam need serios mounting... to be able to focus on the mirrror directly
[23:38:37] <dmess> mine is supposed to be mobile to all extent so i cant build too serious
[23:40:31] <dmess> but the proper combo of tube length and lens.. sufficient electrical tape.... and support ... is all is needed
[23:42:15] <alex_joni> this looks nice: http://www.astroworks.com/
[23:44:27] <fenn> heh i wonder if it has adaptive optics
[23:44:30] <dmess> probably a little out of my wifes price range...
[23:45:35] <alex_joni> http://www.astroworks.com/specifications.html
[23:45:38] <alex_joni> it's NICE ;)
[23:45:58] <dmess> my 14 yr son got a new guitar... 11 yr old daughter got a keybord... and the middle boy has stopped singing since xmas... someone TAKE ME AWAY...
[23:46:37] <alex_joni> * alex_joni sends your middle boy a set of drums
[23:46:52] <dmess> dont you dare...
[23:47:06] <alex_joni> e-drums, with a big AMP
[23:47:29] <dmess> no i got the little dingtar amp
[23:47:50] <alex_joni> http://dsplabs.cs.utt.ro/~juve/blog/index.cgi/
[23:48:00] <alex_joni> just started my blog ;)
[23:50:23] <dmess> what to do with that eh...
[23:50:36] <alex_joni> keeping track of my website
[23:50:43] <alex_joni> as I'm too lazy to edit php anymore :)
[23:50:51] <alex_joni> and I mostly want to add little comments
[23:51:02] <alex_joni> so blog is the way to go
[23:51:33] <dmess> how does it work??
[23:51:55] <alex_joni> you edit it from the browser
[23:52:08] <alex_joni> like a wiki
[23:52:08] <alex_joni> only a bit smarter
[23:52:11] <dmess> in html??
[23:53:25] <alex_joni> nope, you use some markup
[23:53:35] <alex_joni> like [title this is a title]
[23:54:38] <alex_joni> here's an example page: http://www.logarithmic.net/pfh/aether?action=showcode
[23:54:41] <dmess> just readin.... gotta go out for a bit.. back later... ; )
[23:54:50] <alex_joni> ok.. later
