[00:01:38] <robin_z> meep?
[00:01:52] <robin_z> where is that alex_joni when you want him huh?
[00:06:58] <Jacky^> probably around here :P
[00:07:39] <Jacky^> not far from me .. he sayd
[00:10:37] <robin_z> I wanted to ask him some questions about a welding idea
[00:11:50] <Jacky^> :)
[00:19:28] <robin_z> ahh. plate rider bearings ! .. thats what I need!
[00:58:23] <Jacky^> haha

[01:01:07] <Jacky^> DIY virus
[01:01:10] <Jacky^> I have unfortunately been very busy lately and haven't had the time to write a real virus. So please take a couple of minutes to open Windows and randomly delete 10 or 12 files (including a minimum of 3 system files) and then send this message on to everyone on your mailing list.
[01:02:20] <Jacky^> Thank you for your co-operation. PS:. DIY = Do It Yourself :P
[01:09:54] <Jacky^> Gnight
[01:13:04] <robin_sz> pesky internet ...
[05:00:06] <LawrenceG> why so quiet?
[06:26:07] <Jymmm> absuing a punching bag
[07:03:16] <LawrenceG> * LawrenceG learning about KstreamRipper.... VEEERRRYYY Interesting
[07:16:03] <Jymmm> is that a dvd ripper?
[07:17:38] <LawrenceG> Hi Jymmm ... it saves audio streams from internet radio stations
[07:18:16] <Jymmm> ah, ok. I personally couldn't see a reason for doing that. Unless it was internet talk radio.
[07:18:21] <LawrenceG> list of stations at www.shoutcast.com
[07:19:16] <Jymmm> Yeah, I've wanted to setup a jukebox for a long time. Just no time to do it =)
[07:20:44] <LawrenceG> I ripped all my cd's onto the computer and listen to them while in here... random play is much more interesting than changing albums allday
[07:21:57] <LawrenceG> it looks like a 128kb/s audio stream eats about 35k bytes/sec of download bandwidth (10% of cable connection)
[07:23:01] <LawrenceG> the cool thing is you can fit about 2000 songs on a dvd and the newer dvd players will understand mp3 music disks
[07:24:29] <LawrenceG> It was a bummer when Napster got closed down... I got exposed to a lot of new music that one never hears on the radio
[07:25:46] <LawrenceG> nice when one can listen to a song and either drag it to the trash can or keep it for future listening
[07:26:53] <LawrenceG> it was a great way to find new artists and buy their cd's
[07:27:17] <LawrenceG> well... got to run off to bed.... eyes are slamming shut
[07:42:59] <Jymmm> G'Night LawrenceG
[07:50:11] <anonimasu> hm
[07:50:22] <Jymmm> ?
[07:50:57] <ValarQ> morning folks
[07:51:22] <Jymmm> it's still night here for a few more minutes
[07:51:33] <anonimasu> Jymmm: read earlier about lithium grease
[07:51:36] <anonimasu> err your question
[07:51:53] <Jymmm> any comments anonimasu?
[07:51:59] <anonimasu> if I remember it right there are particles in lithium grease..
[07:53:00] <anonimasu> or well particles/thick/
[07:53:25] <Jymmm> The deed has been done. Got a multipurpose lithium grease
[07:53:44] <anonimasu> ah well, there are better grease for that kind of app :)
[07:53:50] <anonimasu> is it for the ways?
[07:53:54] <anonimasu> ways/rails?
[07:53:57] <Jymmm> the rails, ya.
[07:54:01] <anonimasu> ok
[07:54:04] <Jymmm> and the ballscrew too
[07:54:32] <anonimasu> I use some machine oil for my machine
[07:54:55] <Jymmm> See, they only had HUGE grease guns, or one type of smaller gun. The ***ONLY*** grease cartridge available for the smaller gun was lithium
[07:55:09] <anonimasu> :/
[07:55:12] <anonimasu> how's the machine?
[07:55:18] <Jymmm> unless I wanted to pack the gun by hand.
[07:55:37] <Jymmm> it's sad, very very sad.
[07:55:56] <anonimasu> are you experiencing tyhe learning curve?
[07:56:21] <Jymmm> As I got the cartridge in the grease gun, I find that I didnt have enough clearance to get the gun tip on the zirk fitting.
[07:56:44] <Jymmm> one zirk fitting came out
[07:56:53] <anonimasu> ok
[07:57:00] <anonimasu> have you cut anything?
[07:57:08] <Jymmm> the Z axis is binding
[07:57:16] <Jymmm> at the top 2" still
[07:57:57] <Jymmm> the edge if the Z axis pulley ground itself againest the frame because they didn't mount it far enough away
[07:58:13] <anonimasu> :/
[07:58:55] <anonimasu> I hope I can get work done today so I can play withthe USC
[07:58:57] <Jymmm> the T-Nut for the X motor mount stripped out becasue they only used screws that went in 1/8"
[07:59:21] <anonimasu> the project I am working on will be up for testing
[07:59:30] <anonimasu> today :)
[07:59:36] <Jymmm> and to replace this t nut I have to disassembly the 80/20 frame
[07:59:57] <Jymmm> which was aligned using a flat table are parallel bars.
[08:00:15] <Jymmm> cool
[08:01:03] <Jymmm> I have a DVD ready to play... need to relax a bit. chat at ya later.
[08:01:23] <ValarQ> DVD? this time in the morning?
[08:01:44] <Jymmm> Yeah, been a pretty stressful day.
[08:01:59] <ValarQ> ok, mine has just begun
[08:02:05] <Jymmm> need to unwind
[08:02:21] <Jymmm> it's almost midnight here
[08:02:30] <anonimasu> Jymmm: I am building a system for controlling gearchanges at a racecar ;)
[08:03:20] <Jymmm> anonimasu: If you REALLY want to impress me.... Build a system for controlling dumbasses.
[08:03:34] <anonimasu> Jymmm: I haev no wish to impress you.
[08:03:37] <anonimasu> have..
[08:03:58] <anonimasu> the only thing I wish for is more sleep.
[08:04:49] <anonimasu> Jymmm: 320v pots a end to dumbasses..
[08:05:26] <anonimasu> you just zap them and they end up all nice..
[08:05:37] <ValarQ> i guess 320V could control them...
[08:05:55] <anonimasu> I wish for a zap key..
[08:07:20] <anonimasu> "user error press the ZAP key" *bzzt*
[08:07:39] <ValarQ> :)
[08:09:02] <anonimasu> *looks at 5bears.com*
[08:45:37] <Phydbleep> ValarQ: WARNING! User headspace error, Consult a Neuro-Proctologist NOW... ???
[10:33:08] <ValarQ> Phydbleep: what?
[13:56:03] <Yuga> anyone have les's website?
[14:51:35] <Yuga> anyone have les's website?
[16:57:14] <_AchiestDragon> _AchiestDragon is now known as AchiestDragon
[17:36:47] <Jacky^> halo
[17:46:18] <Jacky^> anyone know how much feedrate can I get using PERIOD = 0.000020 ?
[17:46:39] <Jacky^> is it possible to calculate it ?
[17:47:04] <cradek> your maximum theoretical step rate is half of 1/PERIOD
[17:47:40] <cradek> since the signal can only change once per period, and it takes two changes to make a step
[17:48:21] <Jacky^> hi cradek , I changed PS using a new transformerm 34 V, it go much better now
[17:48:28] <cradek> good
[17:48:48] <Jacky^> but i cant go up to 50 IPM, getting following error
[17:49:03] <Jacky^> I suspect max pulses reached ..
[17:56:52] <Jacky^> i think ballscrews are small :(
[18:08:46] <Jacky^> cradek: 1/0.000020 = 50.000/2 = 25.000 is it right ?
[18:09:03] <Jacky^> what are 25.000, khz ?
[18:41:43] <les> grr
[18:42:01] <Jacky^> O_o
[18:42:01] <robin_sz> trying to scare cats?
[18:42:10] <Jacky^> hi :-)
[18:42:15] <les> I am still trying to find out about emc tool change
[18:42:21] <les> hi robin
[18:42:39] <robin_sz> emc1 or emc2?
[18:42:44] <les> found a nice HSD spindle with ATC
[18:42:47] <les> emc1
[18:43:32] <les> I know there is something there
[18:44:19] <les> I wonder if I need a separate plc
[18:44:33] <robin_sz> I know there is some code .. but I'm not sure there is much in the ways of logic and IO for it
[18:45:16] <les> well if I could just get M06 to talk to an external plc that would be fine
[18:45:38] <les> has to send the tool number of course
[18:45:51] <les> and wait for tool change complete
[18:46:23] <les> need what....three or four bits?
[18:46:29] <robin_sz> and get back a "yeah I did it"
[18:46:36] <les> right
[18:46:37] <robin_sz> and a "no, failed "
[18:46:46] <robin_sz> or "oops, that slot is empty"
[18:47:16] <les> well this hsd is new in box....5 Hp, power drawbar.....$900
[18:47:26] <les> $4700 from distributor
[18:47:44] <robin_sz> bargain
[18:47:47] <robin_sz> bought it?
[18:47:50] <les> it seems
[18:47:58] <robin_sz> eBay?
[18:48:08] <les> I told the seller I prob would.
[18:48:12] <les> yeah ebay
[18:48:22] <robin_sz> ahh
[18:48:33] <les> but I need an inverter
[18:48:55] <les> he also has an HSD inverter, but 3 phase in only
[18:49:17] <les> I would rather not have to run it from the big rotary converter
[18:49:27] <robin_sz> hell no
[18:49:44] <les> Some will run from single phase
[18:49:51] <robin_sz> yeah
[18:49:53] <les> but must be derated perhaps
[18:50:10] <robin_sz> well
[18:50:14] <les> I will call some sales reps and find out
[18:50:20] <robin_sz> its more a question of will the motor rewire
[18:50:47] <les> y-delta?
[18:50:56] <robin_sz> yeah
[18:51:08] <les> HSD can tell me
[18:51:19] <robin_sz> 5hp is mid sized, it probably will
[18:51:43] <les> let me show you the unit
[18:55:06] <les> http://cgi.ebay.com/HSD-ES915-Electrospindle_W0QQitemZ7540422799QQcategoryZ92081QQssPageNameZWD1VQQrdZ1QQcmdZViewItem
[18:55:42] <les> looks good huh?
[18:56:02] <les> private email he says it's new in box
[18:56:23] <les> ceramic ball bearings
[18:56:31] <robin_sz> nice
[18:56:35] <les> iso 30 taper
[18:56:41] <robin_sz> buy it dude, before someone else does
[18:57:01] <les> We are just playing tel tag
[18:57:26] <les> all I need is a not doa promise and i'll take it.
[18:57:54] <les> That picture is from man web site
[18:58:26] <les> just need to make sure it wasn't in a flood, etc
[18:58:41] <robin_sz> "new in box" ...
[18:58:45] <robin_sz> says it all really.
[18:58:48] <les> yeah...
[18:59:09] <les> new in box that was underwater?
[18:59:11] <les> heh
[18:59:23] <Jymmm> les LOL I was JUST gonna say that
[18:59:32] <les> that guy lives below sea level really
[18:59:58] <Jymmm> les : Well, just check for kelp =)
[19:00:04] <robin_sz> seen his other adv
[19:00:12] <les> I think he called once and I missed it...
[19:00:18] <robin_sz> http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=7540238696&ssPageName=MERC_VI_RSCC_Pr4_PcN_BIN_Stores_IT
[19:00:27] <les> all but one phone blown out by storm
[19:00:33] <les> looking
[19:00:59] <robin_sz> State of the art PC based CNC Controller with Linux CNC operating systems
[19:01:59] <les> Yeah I want to talk to that guy for sure
[19:02:13] <les> He is on the road this week he said
[19:02:28] <les> seems to be an emc guy
[19:03:07] <les> so why would he give away that spindle?
[19:03:17] <robin_sz> emc?
[19:03:22] <les> heh
[19:03:38] <robin_sz> what makes you think that?
[19:03:59] <les> just the copy in that add
[19:04:23] <les> obviously emc
[19:04:44] <robin_sz> obviously?
[19:05:01] <les> mentioning rs274d makes me think that
[19:05:15] <les> and the linux cnc comment
[19:05:23] <les> what else could it be
[19:05:28] <robin_sz> possibly .. but there are other linux based CNC apckages out there
[19:05:45] <les> closed source ones?
[19:05:53] <robin_sz> yeah
[19:06:07] <les> well could be
[19:06:24] <robin_sz> could be some embedded thing
[19:06:35] <les> yeah he mentions integrated cam
[19:06:36] <robin_sz> ah, no says pc based
[19:06:41] <les> I didn't see that
[19:06:49] <robin_sz> could be weber systems I guess
[19:07:05] <robin_sz> you'll find out soon enough
[19:07:05] <les> hmm
[19:07:08] <les> yeah
[19:07:39] <les> I would buy his VFD too but HSD says 3 phase only for input
[19:07:47] <robin_sz> hey .. you shoudl see the funny stepper drives we found ...
[19:07:59] <les> yeah?
[19:08:04] <robin_sz> oh . yeah
[19:08:10] <robin_sz> so ... 5V stepper ...
[19:08:17] <robin_sz> bag of darlingtons
[19:08:24] <robin_sz> and a 5v supply
[19:08:30] <robin_sz> on, off ...
[19:08:41] <les> heh
[19:08:57] <robin_sz> there is a deluxe version that give 20% more torque ..
[19:09:10] <robin_sz> uses mosfets, so you dont lose 1 v across the darlington
[19:09:30] <les> I was on Skype with Yuga this morning talking drives etc
[19:09:44] <les> He really wants a 2x3 meter machine
[19:09:54] <robin_sz> they guy claims no load speeds of anything up to 120rpm ...
[19:10:14] <robin_sz> 2x3?
[19:10:14] <les> hmm
[19:10:20] <robin_sz> big
[19:10:22] <les> yeah
[19:10:35] <les> We discussed the ramifications of that
[19:10:36] <robin_sz> I bet he want 300mm ox z axis too
[19:10:41] <les> haha
[19:11:14] <les> well I finally said ok....you have lots of time and money right?
[19:11:26] <robin_sz> so hes looking at rack and pinion, big ballscrews servos the size of logs
[19:11:52] <les> I almost would suggest one of the Chinese machines...but a big risk
[19:11:59] <robin_sz> yeah
[19:12:01] <robin_sz> cheap though
[19:12:09] <les> I told him rack on x, ballscrew y and z
[19:12:31] <robin_sz> possibly rack on Y ...
[19:12:50] <les> Concerning his budget...sent him to Hiwin and andantex
[19:13:02] <les> that is about 2/3 of the cost right there
[19:13:18] <robin_sz> rack is a non-trivial engineering task
[19:13:31] <les> did you ever cost up some andantex rack units?
[19:13:39] <robin_sz> nah
[19:13:50] <les> bet they are thousands
[19:13:58] <robin_sz> we have some cheap rack guys here
[19:14:16] <les> hardened anti backlash?
[19:14:22] <robin_sz> I said cheap
[19:14:26] <les> oh.
[19:14:29] <les> haha
[19:14:52] <robin_sz> good enough for a router
[19:15:10] <les> well the soft steel racks etc are plenty cheap
[19:15:18] <robin_sz> yep
[19:15:30] <les> wouldn't live long though
[19:15:33] <robin_sz> fit em up, weld em on :)
[19:16:10] <les> if the pinion at least were hardened....
[19:16:16] <robin_sz> right
[19:16:24] <robin_sz> they usually are
[19:16:38] <les> might live a few hundred hours I would guess
[19:16:46] <les> or till first crash
[19:17:54] <les> couple mm high soft rack tooth driving couple hundred kG....
[19:18:02] <les> hmmm
[19:19:09] <les> even a minor crash would bend those teeth
[19:19:46] <les> oh well I told him to buy andantex anyway...so no problem.
[19:19:47] <les> haha
[19:21:42] <les> Damn I wish I could find where the tool change code is
[19:21:56] <robin_sz> im not sure there is a lot ...
[19:22:08] <robin_sz> theres lots of tool compensartion code
[19:22:21] <robin_sz> and stuff to stop the machine and let you change it by hand
[19:22:34] <les> prob have to write some stuff in a cannonical function
[19:22:54] <les> communication to a plc is a problem
[19:23:03] <les> I looked and there is nothing
[19:23:26] <les> and out of io too
[19:23:35] <les> must send out the tool number
[19:24:33] <les> but how?
[19:24:48] <robin_sz> dont *think* it does
[19:24:48] <les> parport is used up
[19:25:16] <les> as is stg dig io
[19:25:49] <les> could send an analog sig out to a window comparator
[19:25:50] <robin_sz> if it was anywwhere .l it would be in bridgeporttool.cc
[19:25:59] <les> yeah
[19:26:12] <les> checking
[19:26:35] <robin_sz> etc
[19:27:53] <robin_sz> looks like a lot of the logic is done
[19:28:16] <robin_sz> but still needs the "move over here, do this" stuff
[19:29:49] <robin_sz> theres stuff like:
[19:29:51] <robin_sz> ioStatus.tool.toolInSpindle = 0;
[19:30:02] <les> yeah I see it
[19:30:08] <les> but no comms
[19:30:12] <robin_sz> in reallity, you'd want that to come from some external tool detector switch Iguess
[19:30:21] <les> sure
[19:30:46] <robin_sz> so ... *some* of the logic is there
[19:30:56] <les> you need that and a routine to go to where the carosel or holder is
[19:31:01] <robin_sz> but its going to need fleshing out and some IO
[19:31:15] <robin_sz> and ... logic for handling aborts
[19:31:26] <robin_sz> and "try that again"
[19:31:27] <robin_sz> etc
[19:31:29] <les> might be worth it for me if I score that spindle
[19:31:55] <les> remember...turkey call= 24 manual tool changes a day for me
[19:32:06] <les> you know, with wrenches
[19:32:13] <les> I mean spanners heh
[19:32:22] <les> it is not good.
[19:33:04] <les> Heck even using the power draw bar without a carousel would be a big improvement huh?
[19:33:43] <les> ...while I work out an ATC
[19:35:16] <les> getting too much to do....air electricity generator, paint robot, now atc
[19:36:00] <les> but if I don't up that throughput turkey call and air generator project will conflict
[19:36:06] <les> I want to do both
[19:37:08] <les> I WILL do both
[19:39:21] <robin_sz> you *could write it into the gcode
[19:39:43] <les> yeah I was thinking about that
[19:39:53] <robin_sz> pretty poor way of doin git
[19:40:13] <robin_sz> but you might have problems getting it done otherwise
[19:40:33] <les> like T6 is always followed by a motion routine to go where that tool is
[19:40:46] <robin_sz> my view is that "M06 T2" shoudl be all it needs
[19:40:56] <les> yeah
[19:41:01] <robin_sz> retracts the spindle, moves the gantry
[19:41:09] <robin_sz> does whatever it is that it does
[19:41:11] <les> yup
[19:41:38] <les> but a find replace thing WOULD work as a kluge
[19:41:55] <robin_sz> others think that anyting that moves the machien without the interpreter knowing about it is bad and wrong
[19:42:16] <les> hmm
[19:42:26] <robin_sz> persoanlly, I'd just stick it in a toolchange macro
[19:42:33] <les> yeah
[19:42:43] <robin_sz> so different machine could implement whatver macro they needed to do the business
[19:43:11] <robin_sz> but you'll find some umm, hostility, to motion calls from macros
[19:43:17] <les> well one way or another it can be done
[19:43:22] <robin_sz> yep
[19:43:40] <les> need confirm tool locked and unlocked comms
[19:43:57] <les> one io would be enough for that
[19:44:33] <les> steal one of the lesser used parport bits?
[19:45:06] <robin_sz> could do
[19:45:08] <les> or....
[19:45:11] <robin_sz> or add another port
[19:45:25] <robin_sz> easier in emc2 I think
[19:45:40] <robin_sz> hmm apart from the motion
[19:45:56] <les> used a limit switch to operate a plc to check status...estop if failed
[19:45:58] <robin_sz> seen the USB io exapnder from US DIgital?
[19:46:11] <les> no
[19:46:17] <robin_sz> cute
[19:46:19] <robin_sz> and cheap
[19:46:42] <les> exapnter?
[19:46:43] <robin_sz> and nice IO pins ... as in IO
[19:46:53] <robin_sz> in or out 32 bits
[19:47:52] <les> I am running the adsl modem/router now from usb
[19:47:56] <les> have to
[19:48:03] <les> ethernet got fried
[19:48:08] <robin_sz> oopsy
[19:48:11] <robin_sz> thats HARD to do
[19:48:23] <les> I think it is not as good
[19:48:27] <robin_sz> in the storms?
[19:48:33] <les> yeah
[19:48:39] <robin_sz> wow
[19:48:43] <les> the other router EXPLODED!
[19:48:45] <robin_sz> you need lightning arrestors
[19:48:48] <robin_sz> heh
[19:48:52] <les> yeah
[19:49:00] <robin_sz> I lost some modems that way ...
[19:49:06] <robin_sz> relay was kinda "open plan"
[19:49:06] <les> literally blew up MOVs
[19:49:43] <les> and got to the mb through ethernet and poped the on board stuff
[19:49:51] <les> but otherwise mb is ok
[19:49:52] <robin_sz> get a lightning arrestor ... mine was 100 GBP, but not had trouble since
[19:50:14] <robin_sz> lost a modem every 6 months beofre that
[19:50:27] <les> I will do that....It was a freak thing...but happens every few years
[19:50:58] <les> virtually everyone in town here lost their tv
[19:51:24] <les> fot long sparks/plasma coming out of the mains outlets
[19:51:27] <robin_sz> thats careless
[19:51:28] <les> foot
[19:51:46] <les> and
[19:51:57] <les> we had an earthquake last night
[19:52:01] <robin_sz> heh
[19:52:07] <robin_sz> r7?
[19:52:11] <les> and tropical storm coming
[19:52:21] <les> r5
[19:52:22] <robin_sz> welcome to climate change
[19:52:26] <les> just a jiggle
[19:52:56] <les> heh
[19:53:00] <les> yeah
[19:53:17] <robin_sz> still, you'll enjoy it more whan you are walking into town
[19:53:18] <les> let's see...looking at wather data...
[19:53:51] <robin_sz> I see oil is heading for $70/bbl
[19:53:52] <Jymmm> les : Told ya to stop making moonshine undergrounds in those abandonded mine shafts. See what happens when Stil #22 explodes?! You caused an earthquake!!!!
[19:54:08] <les> haha
[19:54:13] <robin_sz> Jymmm: you dont know where he lives
[19:54:19] <les> 52.25 in rain so far this year
[19:54:32] <robin_sz> Jymmm: 1) its too wet for anything underground
[19:54:47] <robin_sz> 2) they are *proud* of their moonshine stills out there
[19:54:47] <les> water...
[19:55:12] <les> aw all the moonshiners now make meth
[19:55:17] <robin_sz> heh
[19:55:21] <les> i make beer
[19:55:29] <robin_sz> Jymmm: so waht was the figure from that test?
[19:55:30] <les> then I make urine.
[19:56:30] <cncuser> hi folks )
[19:57:03] <les> howdy cncuser
[19:57:12] <robin_sz> evenig
[19:57:29] <robin_sz> austria?
[19:57:33] <cncuser> jo les, robin
[19:57:43] <cncuser> yes, austria
[19:58:48] <robin_sz> * robin_sz puts on some lederhosen
[19:58:52] <cncuser> my pc brokedown 2 weeks ago, i started emc 3 weeks ago ;) i am back
[19:59:22] <les> got it working?
[19:59:37] <cncuser> probs compiling, mom
[19:59:40] <cncuser> mes away ;)
[20:00:22] <robin_sz> ooh, rabbit ...
[20:00:28] <les> I compile ok but stick with an old version
[20:00:34] <robin_sz> you know .. I could shoot that from here
[20:00:46] <les> out the window?
[20:00:53] <robin_sz> yeah ...
[20:01:11] <robin_sz> but since its sitting in my neighbours bedroom window, I probably shouldnt
[20:01:20] <les> heh
[20:01:27] <les> prob rabid?
[20:01:48] <robin_sz> its inside on the first floor, lets assume its a pet
[20:02:00] <robin_sz> we dont have rabies in the UK
[20:02:11] <les> do rabbits get rabid (or rabbid)
[20:02:16] <robin_sz> no idea
[20:02:17] <les> no rabies?
[20:02:19] <les> hmm
[20:02:23] <robin_sz> they get myxy
[20:02:34] <robin_sz> and lead posining
[20:03:36] <les> animals doing unusual things here are often rabid
[20:03:57] <robin_sz> rabies has not made it to the UK, france etc yes, UK no
[20:04:05] <robin_sz> except for the odd bat
[20:04:14] <robin_sz> like once every 20 years
[20:04:17] <les> I see
[20:05:08] <les> well, I had better get to work. I am 6 days behind due to the storm
[20:05:13] <robin_sz> heh
[20:05:19] <les> No internet= out of business
[20:05:22] <robin_sz> hv generators?
[20:05:39] <les> foot long plasmas?
[20:05:46] <robin_sz> ahh
[20:05:49] <robin_sz> hmm
[20:05:53] <les> few hundred thousand volts I guess
[20:06:01] <robin_sz> so ... you are developping a HV generator
[20:06:10] <les> oh...yes
[20:06:14] <robin_sz> the entire town got nuked with foot long plasma out of the mains sockets
[20:06:21] <robin_sz> hmmm ....
[20:06:24] <les> yup
[20:06:38] <les> I only need 100kv 5 watts
[20:06:38] <robin_sz> sounds "coincidental"
[20:06:43] <les> heh
[20:07:04] <les> And it appears that my gizmo will do it!
[20:07:09] <robin_sz> neat
[20:07:14] <les> "No moving parts"
[20:07:16] <robin_sz> and how often does the reed snap?
[20:07:17] <les> !!
[20:07:25] <les> no reeds
[20:07:27] <les> heh
[20:07:33] <robin_sz> cute
[20:07:41] <robin_sz> does it deafen dogs?
[20:08:04] <les> well....10^5 pascal overpressure...
[20:08:14] <les> 40 kHz
[20:08:22] <les> but going up to about 75
[20:08:29] <robin_sz> 120db at 1m?
[20:08:38] <les> more
[20:08:46] <robin_sz> coo
[20:08:51] <les> very nonlinear
[20:08:59] <les> supersonic shock wave
[20:09:06] <robin_sz> needs hearing protection?
[20:09:16] <les> so linear analysis does not work
[20:09:31] <les> I do have protection yes
[20:09:45] <robin_sz> what about for user of the product?
[20:09:55] <les> if focused, sound of that intensity will light fires
[20:10:06] <robin_sz> or will it be enclosed and silenced?
[20:10:18] <les> inside gun handle
[20:10:52] <les> course if I screw up it will focus on the users brain and make an instant vegtable
[20:10:53] <robin_sz> gotta get it under 80dbA I guess
[20:11:16] <les> fortunately a weighting does nor go that high
[20:11:28] <robin_sz> firtuneatley?
[20:11:36] <les> hey ultrasonic cleaners are safe right?
[20:11:42] <robin_sz> mmmm ...
[20:12:02] <robin_sz> I always understood that just because it was too high to hear
[20:12:10] <les> just don't use em to wash your hair
[20:12:12] <robin_sz> did not mean it was too high to damage your hearing
[20:12:15] <robin_sz> loud is loud
[20:12:31] <les> yeah but volume velocity is really low
[20:12:51] <robin_sz> so runs off a ballon full of air for a week
[20:12:59] <les> oops I'm being linear again
[20:13:18] <les> uses about 0.7 scfm right now
[20:13:30] <les> not much
[20:13:34] <robin_sz> nope
[20:13:39] <robin_sz> not for the applicatrion
[20:13:52] <robin_sz> I just sold my screw compressor
[20:13:55] <les> right ...some of the guns use 10+ I guess
[20:14:01] <robin_sz> WAY too big for what I needed
[20:14:02] <Jacky^> it's 35 V capacitors
[20:14:09] <Jacky^> ops,
[20:14:17] <Jacky^> ok for 32 V ps ?
[20:14:21] <robin_sz> 62CFM
[20:14:26] <les> yikes
[20:14:35] <robin_sz> FAR too big ...
[20:14:44] <robin_sz> sold it to a guy setting up a body shop ...
[20:14:47] <robin_sz> eerrrr ...
[20:14:51] <robin_sz> ah well,
[20:15:00] <robin_sz> it will keep him warm in winter
[20:15:03] <les> I need more air...about 5 kW at least
[20:15:42] <robin_sz> for the shop?
[20:15:45] <les> I am throwing a lot of money back into the business
[20:15:54] <robin_sz> get a hydorvane
[20:15:58] <robin_sz> hydrovane
[20:15:59] <les> To keep from buying airplanes I guess
[20:16:06] <cncuser> ill be back
[20:16:07] <cncuser> ;)
[20:16:09] <les> k
[20:16:54] <les> If I just buy tools I can resist airplanes and girly Audis
[20:17:20] <robin_sz> right ..
[20:17:25] <robin_sz> and .. speaking of which
[20:17:29] <robin_sz> I must go do soem work
[20:17:30] <les> ?
[20:17:38] <les> haha
[20:17:39] <robin_sz> earn some $$$
[20:17:42] <robin_sz> later
[20:17:44] <les> me too.
[20:24:32] <Jymmm> les : Here ya go.... http://www.fu-fme.com/
[20:24:42] <Jacky^> hey Jymmm
[20:25:37] <Jacky^> I bought 24V transformer, now steppers are working better
[20:25:48] <Jymmm> cool beans
[20:26:13] <Jacky^> i need to change capacitors of PS
[20:26:35] <Jacky^> do you think 35 V capacitors are ok for 32 V ?
[20:26:57] <Jymmm> Personally, I wouldn't. More is always better.
[20:27:20] <Jacky^> 50 V could be better ..
[20:27:24] <Jymmm> yeah
[20:27:34] <Jacky^> ok :)
[20:29:34] <AchiestDragon> an other good roule of thumb with power supplys is current rating , if you need say 2A from it use a 4A psu ,
[20:31:28] <Jacky^> AchiestDragon: i've not much experience about :(
[20:32:13] <Jacky^> I bought a transformer 220V - 24 V 200 VA
[20:32:22] <Jymmm> ok, this just bugs me in general... When in the hell have someone said "Power Supply Unit", you say "Power Supply". it's PS damnit, not PSU!!!
[20:32:39] <Jacky^> my motors are 2A/phase i think is enough..
[20:32:56] <Jacky^> 3 axis
[20:33:17] <Jymmm> AchiestDragon not directly targeted at you, just everything I see 'PSU' in email/forum/etc it bugs the crap out of me =)
[20:33:26] <AchiestDragon> lol
[20:33:45] <AchiestDragon> psu is the proper abbreviation for it
[20:34:07] <Jacky^> that's ok
[20:34:07] <Jymmm> When have you EVER actually spoke the words "Power Supply Unit" ?
[20:34:12] <AchiestDragon> 24v on a 200va psu is about 8a
[20:34:34] <Jacky^> its enough..
[20:35:11] <Jacky^> 8000 uF capacitors should also be ok
[20:35:38] <Jacky^> i will use small capacitors
[20:35:45] <Jymmm> * Jymmm can tell that Jacky^ didn't read the whitepaper.
[20:35:48] <AchiestDragon> so if you got 2a phase then 6a total , usualy you dont drive 3 phases at once unless your half stepping , then you got 12A total :(
[20:35:49] <Jacky^> instead of big capacitors
[20:36:15] <Jacky^> Jymmm: not yet (at all) i'm tryng to translate and understand :\
[20:36:28] <Jymmm> Jacky^ ah, ok.
[20:36:39] <Jacky^> small capacitors should be more 'fast' on peak current
[20:36:46] <Jacky^> for what I know ..
[20:36:59] <Jacky^> maybe better
[20:37:19] <AchiestDragon> the rtansformer you have should do , would recomend dubblining it if the machine is going to be in almost constant use
[20:38:12] <AchiestDragon> or the transformer is goning to get hot and will cook the insulation if on 24/7
[20:38:50] <Jacky^> ok
[20:39:03] <AchiestDragon> if using the machine for say 2 to 3hrs at a time then should be ok with the one you have
[20:39:23] <Jacky^> it should no suffer , first, because is oversized
[20:39:48] <Jacky^> second, also have heat sink with fan up
[20:41:11] <Jacky^> i was reading in whitepapers, in some case an additional capacitor 470 uF is used on drivers
[20:41:16] <Jacky^> interesting ..
[20:41:17] <AchiestDragon> the problem you may have if half stepping (driving 2 phazes at the same time per stepper ) and running in all 3 axis at the same time is that the motors get less power than otherwise
[20:42:23] <Jacky^> 2 phase at the same time ? of the same motor ??
[20:42:38] <Jacky^> it sound to me strange ..
[20:43:19] <Jacky^> anyway i'm using half winding motors
[20:43:51] <AchiestDragon> 4 phase steppers sequence one then the next etc , when half stepping you leave the last one on and power the next so it moves half way between the two so half a step
[20:44:09] <Jacky^> ah.. ok
[20:48:29] <Jacky^> how much axis emc can use ?
[20:48:34] <Jymmm> 6
[20:49:01] <Jacky^> nice :P
[20:49:40] <Jacky^> for 6 axis need to use 2 parport right ?
[21:12:02] <cradek> no
[21:12:15] <cradek> there are 12 bits on a parallel port
[21:14:36] <Jacky^> cradek: thanks
[21:14:56] <cradek> of course you then need the other parallel port for things like home switches
[21:16:13] <Jacky^> i know pin 2-8 are used now ..
[21:16:42] <Jacky^> sorry.. no ..
[21:17:35] <Jacky^> pin 2-7
[21:20:10] <Jacky^> I want to build a small arm using 6 small steppers, just for fun
[21:20:58] <Jacky^> some ULN ic should enough maybe ..
[21:22:01] <cradek> you still need somethign to interpret the step/dir
[21:22:15] <cradek> you could do phase outputs but that would take two full parports for 6 axes
[21:24:04] <Jacky^> ok, i've 3 parports(2 isa 1 pci)
[21:24:21] <cradek> wow
[21:24:24] <Jacky^> surplus cards but are working fine
[21:24:27] <Jacky^> :)
[21:24:36] <cradek> then phase outputs will be simplest
[21:24:42] <Jacky^> it will help me to learn more
[21:26:30] <Jacky^> I want to try something like an arm that write with a pencil ..
[21:26:55] <Jacky^> it will be hard, but funny :)
[21:27:02] <cradek> sounds like complicated kinematics
[21:27:36] <Jacky^> something like this: http://www.sorgonet.com/robotics/sicario/
[21:27:47] <Jacky^> but i don't like this project
[21:28:07] <Jacky^> it doesnt use Linux, and are a little expensive..
[21:28:27] <Jacky^> i want to try with small steppers, just for fun
[21:29:07] <Jacky^> also, the sicario project use DC motors.. if I understand well
[22:30:55] <Jymmm> Jymmm is now known as Red70sShow
[22:30:56] <Red70sShow> Red70sShow is now known as Jymmm
[22:56:52] <Jacky^> well, PS circuit updated :)
[22:57:18] <Jymmm> 42KVDC @ 1KA
[22:57:27] <Jacky^> haha
[23:03:44] <cncuser> rehi
[23:03:57] <Jacky^> cncuser: wb
[23:04:43] <cncuser> i got an adeos patched kernel, rtai installed (/usr/realtime) and the emc2 cvs source
[23:04:50] <cncuser> kernel is 2.4.29
[23:05:19] <cncuser> i get Makefile:5: /usr/src/linux-2.4.29/../../Makefile.inc: No such file or directory , make[4]: *** No rule to make target `/usr/src/linux-2.4.29/../../Makefile.inc'. Stop
[23:05:36] <cncuser> when running make after doing src/configure rtdir=/usr/realtime
[23:05:47] <cncuser> anyone any ideas ?
[23:09:00] <Jacky^> cncuser: it seem wrong src dir
[23:09:30] <cncuser> hmmm
[23:09:33] <Jacky^> if I remember well, someone sayd to compile in home dir ..
[23:10:05] <cncuser> hmm, ok i try
[23:10:37] <Jacky^> good luck ;)
[23:11:16] <cncuser> hmm, didnt work
[23:12:33] <cncuser> ic it mixes up something
[23:12:44] <cncuser> checking /usr/src/kernel-headers-2.6.10-adeos/include/linux/version.h usability... yes
[23:12:56] <cncuser> sh-2.05b# cat /proc/version
[23:12:56] <cncuser> Linux version 2.4.29-adeos
[23:13:01] <cncuser> :)
[23:20:35] <cncuser> i also have a 2.6.19 adeos kernel installed, but it is not active, gonna find out howto specify to use 2.4.29
[23:21:42] <cncuser> ./configure --with-rtai=/usr/realtime ;)
[23:24:04] <CIA-9> 03jmkasunich * 10emc2/src/hal/utils/ (6 files): modified scope to save settings on shutdown and restore them on startup, horizontal and vertical working, more later
[23:24:16] <cncuser> i updatet the wiki
[23:25:49] <cncuser> cia-9: ah, i reconized when i used it last time. it kept the axisvalues. nice behavior
[23:48:58] <robin_sz> meep?
[23:49:30] <robin_sz> * robin_sz wonders if he ought to say "meep" mor often
[23:52:13] <Jacky^> ciao robin_sz :)
[23:52:33] <robin_sz> bon soir mon brave
[23:52:39] <Jacky^> hehe
[23:56:02] <Jacky^> Here information on Epson stepper motors
[23:56:32] <Jacky^> I messured the phase current thru the coils of serveral epson stepper motors. Used a small ressistor to mesure max and min currents thru a coil.
[23:56:52] <Jacky^> Re: Here information on Epson stepper motors
[23:57:01] <Jacky^> plz tell me about the ratings of the stepper motor like torque, input voltage and the current.
[23:57:04] <Jacky^> thank you.
[23:57:06] <Jacky^> lol
[23:57:30] <Jacky^> how is possible to measure current of stepper ?
[23:58:49] <robin_sz> sorry, was on another channel
[23:59:18] <robin_sz> be more clear with the question
[23:59:42] <robin_sz> do you mean "how is it possible to measure the actual current"
[23:59:45] <robin_sz> or ...
[23:59:51] <robin_sz> do you mean "how is it possible to measure the rated current"
