#linuxcnc | Logs for 2012-04-28

[00:04:28] <alex4nder> yoh
[00:06:57] <jdhNC> I guess I should mention 'rm foo.bar' afterwards for completeness.
[00:07:39] <alex4nder> Valen: which intel board?
[00:08:26] <Tom_itx> jdhNC why? microsoft doesn't
[00:23:05] <Jymmm> jdhNC: Initially, I misread the of= as /dev/sdx, BUT my biggest bitch was that you randomly gave a dangerous command not directed to anyoen specifically and more so that you gave no hint that one should be careful not to typo the command as they could fuck things up. People on irc will see some command and just try it out not knowing. A little warning would have been nice for those that have no clue.
[00:24:22] <ReadError> alex4nder
[00:24:27] <ReadError> what kinda backlash you get?
[00:24:37] <jdhNC> someone got you to read mail really fast one time didn't they.
[00:24:40] <ReadError> im at like 0.0034
[00:25:18] <ReadError> Jymmm: im a linux system admin
[00:25:29] <ReadError> i know _alot_ about linux
[00:25:42] <ReadError> not so much about CNC/machining
[00:26:10] <ReadError> and i noticed the of= didnt output to any device
[00:26:12] <ReadError> but rather a file
[00:27:03] <Jymmm> jdhNC: No, just when you have a channel of 500+ on a somewhat learning irc network there have been times that system went poof becasue the person gave no warning. You wouldn't put a knife/gun in the table and walk away for a few moments, would you?
[00:27:28] <ReadError> when in doubt, rm -rf /
[00:27:49] <Tom_itx> it would thin out the fools
[00:27:49] <Jymmm> ReadError: That too you shouldn't just put on irc
[00:27:57] <jdhNC> yeah, that's "read mail really fast"
[00:28:18] <Jymmm> ReadError: and you KNOW better, some don't
[00:28:27] <Tom_itx> irc cops are doing a random drug test tonight
[00:29:15] <Jymmm> Tom_itx: I'll remember that the next time you might need some help and I give a command for you to try.
[00:29:18] <Tom_itx> i wouldn't be foolish enough to try something i didn't first understand
[00:29:29] <Jymmm> Uh huh
[00:29:42] <Tom_itx> so i wouldn't try your command without finding out what it did
[00:29:57] <Jymmm> only out of fear now
[00:30:02] <Tom_itx> nope
[00:30:06] <Tom_itx> just how i roll
[00:30:36] <alex4nder> ReadError: sup
[00:31:01] <alex4nder> ReadError: I'm at about 2 thou on X and Y and .. pretty much nothing on Z
[00:31:31] <Tom_itx> i ask questions here and expect good advice but i'd be a fool if i didn't follow up and find out for myself first
[00:31:46] <ReadError> alex4nder: did you adjust the nuts?
[00:31:47] <ReadError> or stock
[00:31:59] <alex4nder> I adjusted the nuts.
[00:32:08] <alex4nder> well, the nuts that preload the bearings
[00:32:13] <alex4nder> I also broke a set of bearings because of it
[00:32:14] <ReadError> oh i havnt done anything yet
[00:32:20] <ReadError> ide rtfm
[00:32:24] <ReadError> but there is nothing ;/
[00:32:35] <alex4nder> I'd spend some time milling
[00:32:47] <alex4nder> the only reason I even touched mine is because my mill came with handles
[00:32:48] <Tom_itx> are there springs behind the preloaded nuts?
[00:32:51] <alex4nder> no
[00:33:12] <Tom_itx> that would be a good start
[00:33:23] <alex4nder> there is bearing, spacer, bearing, dial bearing, coupler half, nut
[00:33:24] <ReadError> alex4nder: I got it dialed in using compensation
[00:33:29] <alex4nder> ReadError: yah
[00:33:35] <alex4nder> just use your mill
[00:33:37] <ReadError> where i can move it .0001
[00:33:44] <ReadError> with the compensation
[00:33:52] <ReadError> but thats w/o a load
[00:34:07] <alex4nder> what are you measuring 1/10 of a thou with?
[00:34:14] <ReadError> well
[00:34:23] <ReadError> i move it 10x 0.0001
[00:34:28] <alex4nder> sure
[00:34:30] <alex4nder> cool
[00:34:31] <ReadError> and it goes moves 0.001
[00:34:43] <ReadError> i just press it 10 times @ 0.0001
[00:34:49] <ReadError> and it end up being 0.001
[00:35:09] <alex4nder> next you'll be freaking out about your runout. ;)
[00:36:01] <Tom_itx> absolutely
[00:36:29] <alex4nder> ReadError: what're you going to mill this weekend?
[00:37:48] <ReadError> probably just some engraving'
[00:37:55] <ReadError> took some time learning the software
[00:38:02] <ReadError> and getting it set up
[00:38:05] <alex4nder> nice
[00:38:08] <ReadError> but now i think im good too go
[00:38:25] <alex4nder> time to go break something
[00:38:28] <alex4nder> maybe an endmill
[00:38:36] <ReadError> hah yea
[00:38:43] <ReadError> i got some cheap dremel bits
[00:38:45] <ReadError> to test with
[00:38:58] <ReadError> the ball and cone style one
[00:39:24] <Tom_itx> get some real cutters
[00:40:02] <alex4nder> one thing worth noting about those ER16 collets: you can run undersized tools in them, but don't go oversized.
[00:40:43] <alex4nder> there's a range for a reason
[00:41:44] <ReadError> i dont understand why the CR/ER has a different spindle
[00:42:19] <alex4nder> because the threads/size is different
[00:54:01] <ReadError> but why the difference?
[00:55:29] <alex4nder> wait
[00:55:33] <alex4nder> CR means computer ready
[00:55:45] <alex4nder> are you sure you're not talking about the old Taig spindle that the lathe still uses?
[00:55:57] <alex4nder> the 3/4"-16 threads
[00:56:17] <ReadError> nah i remember seeing the CR and ER spindles though
[00:56:29] <alex4nder> there is no CR spindle
[00:57:30] <alex4nder> there's the ER non-CR model, which has an ER16 spindle with a non-continuous duty motor
[00:57:38] <alex4nder> and then there's the actual 3/4"-16 taig spindle
[00:57:51] <alex4nder> which the old mills used, and the lathes still use
[00:58:21] <alex4nder> (which is one of the reasons I waited so long to buy a taig)
[01:03:59] <ReadError> ohhh ok
[02:30:13] <Jymmm> Valen: Just FYI... google MCP73831/2
[02:39:22] <Jymmm> Valen: It has a "Automatic Recharge" if vBAT goes below factory threshold, so may not be good for solar charging in case a cloud goes by and starts a new charge cycle.
[04:24:09] <Valen> Jymmm: they all generally do have that
[04:24:21] <Valen> I have used that charger IC quite recently
[04:24:40] <Valen> its not going to be a big issue for you i don't think
[04:25:30] <Jymmm> Valen: I just wouldn't want to excessively kill the cell due to patchy cloud cover.
[04:26:06] <Valen> whats the voltage the auto recharge starts again? i think it varies for different sub models in that line
[04:26:34] <Jymmm> most do , what, 500 cycles or so. pathcy cloud cover over 6 hours could mean 10-30 (restart) cycles I'm guessing.
[04:26:50] <Valen> well probably not i'm thinking
[04:26:51] <Jymmm> Valen: it's sensative as all hell... 50mV
[04:27:08] <Valen> because the voltage won't actually sag a great deal as a rule
[04:27:54] <Jymmm> You know, I have a cheap data logging DMM. Maybe I just need to toss out my solar blanket and see what it does
[04:28:05] <Valen> its a good place to start
[04:28:16] <Valen> those IC's will be happy with 5V at 500ma
[04:28:23] <Valen> if you can provide that at all times its good
[04:29:00] <Jymmm> I really should get a solar controller, just not sure if the one I'm looking as would be good for charging Li-Ion as it does PWM charging of Gelcells
[04:29:22] <Valen> pwm is just a control scheme
[04:29:33] <Valen> 99% of all modern power electronics is pwm
[04:29:59] <Jymmm> Well, it's intende to help prevent sulfication in LEadAcid gelcells
[04:30:31] <Jymmm> Valen: This is the one I'm considering... http://www.morningstarcorp.com/en/sun-guard
[04:30:33] <Valen> so they presumably boost the voltage output of the PWM stage up somewhat from time to time
[04:31:29] <Valen> their "100% pwm duty cycle" thing is because most of the pwm systems use ringing on the fet to generate voltage to drive the fet
[04:31:38] <Valen> so they cant run at 100% duty cycle
[04:32:45] <Jymmm> PWM Setpoint 14.1 V
[04:35:42] <Jymmm> Valen: Heh, maybe I can find a 10 Farad (not uF), cap to balance out the clouds =) lol
[04:36:03] <Jymmm> Valen: and no bigger than 4 stacked US Quarters or so =)
[04:36:03] <Valen> perhaps not
[04:36:34] <Valen> the problem is when you suck 50% of the charge out of them the voltage is half what you started with
[04:36:34] <Jymmm> Well, maybe not 10F, but I have seen 1F that size
[04:36:50] <Valen> you can get 55F in small packages
[04:37:01] <Jymmm> WOOHOO!!!
[04:37:12] <Jymmm> and less than $4 USD, right? lol
[04:37:57] <Valen> somewhere around that price actually
[04:38:43] <Jymmm> Oh, cool. Maybe that might add some benefit. I have a "shake flashlight" that uses a super cap like that instead of a battery for storage.
[04:41:04] <Jymmm> Valen: did you check out that sony battery?
[04:41:13] <Valen> no?
[04:41:17] <Jymmm> hang on
[04:42:06] <Jymmm> Valen: I got my on sale for $10 USD... http://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=2&ved=0CDwQtwIwAQ&url=http%3A%2F%2Fwww.youtube.com%2Fwatch%3Fv%3DCxO-_E8uqN4&ei=-LibT7raH-3YiALO69hx&usg=AFQjCNGSi-wUyvhScHSE1C1jAZRnIRJYUA
[04:42:38] <Jymmm> Valen: First thing I did was crack it open. It uses an 18650 battery
[04:42:51] <Valen> again thats kinda like saying its a D size battery
[04:42:57] <Valen> doesn't describe the chemistry
[04:43:29] <Jymmm> Valen: Well, I've never seen an 18650 in anythign other than Li-Ion tyvm
[04:44:10] <Valen> theres lithium ion, lithium ion polymer, lithium nano-phosphate and life
[04:44:16] <Jymmm> Valen: just check out the video
[04:44:26] <Valen> eh its somebody flogging some crap
[04:44:39] <Valen> they have a lipo cell and a boost converter
[04:44:44] <Jymmm> http://www.youtube.com/watch?v=CxO-_E8uqN4
[04:44:47] <Valen> aka minty-boost but "professional
[04:45:25] <Valen> and knowing sony if you plug something non sony into it it'll catch fire or be incompatible
[04:45:58] <Jymmm> LOL,well they show a ipad, blackberry, and a sony phone being used.
[04:46:14] <Jymmm> They are FINALLY changing their attitude it seems
[04:47:28] <Jymmm> Valen: It's slick enough to keep in the glovebox in a pnch
[04:47:46] <Jymmm> pinch
[04:48:07] <Valen> http://www.ladyada.net/make/mintyboost/
[04:49:02] <Jymmm> Valen: http://www.suntekstore.com/goods-14002287-lm2577s_dc-dc_adjustable_step-up_power_supply_module.html
[04:49:45] <Valen> eh something like that
[04:50:04] <Jymmm> I'm still trying to figure out how to MOUNT it before buying it
[04:50:20] <Jymmm> the fours holes are where you solder the leads
[04:51:02] <Jymmm> Valen: Heh, 18V@2A from a pair of AA's =)
[04:52:22] <Jymmm> Valen: that site has couplers and some other linear rail stuff too in the DIY section.
[04:52:37] <Jymmm> Alright, I'm outta here for a while laters!
[06:04:00] <DJ9DJ> tag
[06:04:18] <DJ9DJ> hi everyone
[08:54:29] <JT-Shop> morning
[08:55:25] <archivist> bit of a late morning!
[09:11:00] * Tom_itx watches the sun rise over the hills in swampeast Mo
[09:12:29] <archivist> 3 in the afternoon and not seen the sun yet
[09:12:51] * Tom_itx wonders if all the birds awoke to cannon fire
[09:14:24] <JT-Shop> not yet but today is a good day to install the elevator
[09:17:05] <JT-Shop> no sun here either
[09:18:57] <Tom_itx> hauled a load to the dump and mowed, now i'm sitting here hacking up the weeds
[09:20:55] <archivist> been ground clearing here, space for wood delivery eventually
[09:21:30] <archivist> and digging in the shed for a motor, cant find details on it though
[09:23:43] <Jymmm> JT-Shop: Got Boom?
[09:23:50] <archivist> identifying bldc types seems a black art
[09:24:26] <Jymmm> JT-Shop: Got KaBoom?
[09:26:19] <Jymmm> archivist: they look kinds black box'ish
[09:31:37] <Jymmm> I guess this is one of those spam websites... http://dcelectricmotorss.com/brush-dc-motor/
[09:39:13] <andypugh> archivist: I think you can probably figure them out using logic, but it is quicker just to run through the patterns and see which works.
[09:40:42] <archivist> this one I have here looks like a stepper, but feels like there is no magnetism, but the rotor is magnetised, 5 wire no sensors and 16 slots in the stator
[09:41:25] <archivist> not got a meter on it yet, label states 12v dc
[09:42:38] <andypugh> No sensors is a bit funny.
[09:44:25] <archivist> well the model aircraft outrunner types are sensorless
[09:44:47] <andypugh> But only 3 wires.
[09:46:01] <archivist> I feel this is a strange unipolar stepper
[09:47:08] <archivist> andypugh, have you seen this one http://www.raynerd.co.uk/?p=1562
[09:49:20] <andypugh> That's rather neatly done. He might need an air-stirrer, but I can see it working very well.
[09:52:12] <archivist> does look nice, motor and driver are not that expensive perhaps fleabay motor 110855214840 mounted on shaft and collet holder 150802219480
[10:02:12] <andypugh> Those eBay collet holders are good for all sorts of things like that.
[10:28:28] <skunkworks__> we did something similar on a bigger scale... http://electronicsam.com/images/KandT/spindle/DSC03425.JPG
[10:28:55] <skunkworks__> http://electronicsam.com/images/KandT/spindle/DSC03427.JPG
[10:29:28] <skunkworks__> http://electronicsam.com/images/KandT/spindle/DSC03429.JPG
[10:29:37] <skunkworks__> iirc - it was a wheel balancing motor
[10:31:28] <andypugh> High speed spindle for the K&T?
[10:31:56] <skunkworks__> higher - yes. It does about 10k just plugged in the wall.. (universal motor)
[10:35:59] <skunkworks__> bbl
[10:47:47] <JT-Shop> Jymmm: not yet, but soon
[10:57:35] <alex4nder> hey
[11:02:17] <JT-Shop> http://www.raynerd.co.uk/?p=1557
[11:22:35] <andypugh> That's vaguely similar to my faster CNC dividing head (that I made for gear hobbling)
[11:23:23] <andypugh> <turns off spell-checking>
[11:24:09] * archivist wants to see a hobbled gear up close
[11:27:13] <archivist> I need to cnc http://www.archivist.info/cnc/works/P1010213.JPG, pic when at work, buried here too , a barber coleman hobbing machine
[11:30:59] <andypugh> Looks interesting
[11:32:24] <skunkKandT> andypugh: did you use a bushing or ball bearings?
[11:33:16] <andypugh> Tapir rollers
[11:34:29] <archivist> did the tapir mind
[11:39:08] <andypugh> He was a little Morose.
[11:39:56] <andypugh> (Sorry, in the Motor Club we always talk about "morose tapirs" rather than "Morse tapers"
[13:15:51] <tom3p> hello, how would i find source for visiteur's offset in kinematics?
[13:15:52] <tom3p> ""I have it for the nozzle height control - customized thc HAL module calculates the offset and then I feed it in kinematics module.""
[13:16:08] <cradek> ask him, I guess
[13:16:34] <tom3p> i see i edited that from 'where would i to how would i, shame on me
[13:16:37] <cradek> we have some thc type stuff in our distribution, but I don't know if it's what he's talking about
[13:17:50] <tom3p> its a different approach from John Thorntons (next line in quote makes that specific), i'll try to catch him online thx
[13:18:11] <cradek> is he here sometimes? I'm not sure
[13:18:23] <cradek> I think he might be list only
[13:18:56] <tom3p> old irc history ""<viesturs> Peter, thanks for the explanatio..."" not often tho
[13:20:14] <tom3p> btw i got openSCAM running the CDS.ngc, now if i could virtually mike it, i could virtually certify the virtual machine :)
[13:20:42] <tom3p> there a new .deb on openSCAM site
[13:20:51] <andypugh> You only see Visteurs here when he is on a customer site and horribly stuck.
[13:20:57] <cradek> cool!
[13:21:08] <cradek> I ran it but didn't really see it working right
[13:21:15] <cradek> andypugh: oh right, that guy, I forgot :-)
[13:25:26] <tom3p> http://imagebin.org/210144
[13:26:17] <andypugh> You mean there is a FOSS CAM package that actually works?
[13:26:59] <tom3p> a strange new usage of the word 'work' that i was previously unaware of ( A Dent )
[13:27:11] <tom3p> works pretty good so far
[13:27:55] <archivist> wrong to call it cam as it is a visualiser http://openscam.com/
[13:28:14] <tom3p> or is it 'WORK?!?' ( M G Krebs )
[13:28:21] <tom3p> SimulatedCAM
[13:28:45] <archivist> simulated cnc
[13:29:35] <tom3p> yes thats better
[13:30:55] <tom3p> 5 min ETA till done 'cutting'
[13:49:51] <tom3p> http://imagebin.org/210149 didnt render , then did, and crazy angle to try to get light better ( hey its new software )
[13:54:11] <andypugh> Pretty
[15:43:15] <andypugh> I just realised, my Youtube channel has 55 subscribers. That's a little scary.
[15:48:30] <jdhNC> you r0ck.
[15:50:10] <andypugh> hmm, skunkworks has a lot more views (100,000) and 35 subscribers.
[15:50:46] <MrZulu> mmm
[15:55:46] <alex4nder> hey
[15:55:54] <DJ9DJ> gn8
[15:58:47] <Tecan> nitric acid eats steel ? neat brb
[16:05:23] <archivist> andypugh, there seems no logic to the number of views one gets
[16:06:53] <archivist> hmm 65 subscribers, I should make more vids
[16:07:06] <andypugh> Sounds like you should, you are a star!
[16:07:33] <archivist> one of the vids has huge numbers
[16:11:43] <andypugh> link?
[16:13:19] <archivist> my channel is davethearchivist
[16:17:34] <archivist> I wonder about pulling the final gcode test cut of an escape wheel as I get dislikes because it shows the previous test cuts
[16:18:13] <andypugh> Half a million views of the helical gear is a lot.
[16:18:54] <archivist> youtube keeps wanting me to add adverts probably because of the qty
[16:19:10] <pfred1> yeah monetize!
[16:19:10] <andypugh> Yeah, you could be a hundredaire
[16:19:23] <archivist> pence maybe
[16:19:41] <pfred1> google cashed in that is for sure
[16:20:20] <ReadError> pfred1: what did you grab today at the flea market?
[16:20:38] <pfred1> ReadError flea market tomorrow garage sales today
[16:21:11] <pfred1> ReadError it was slim pickins out there today though I did get this http://i.imgur.com/xXo9K.jpg
[16:21:31] <ReadError> lol nice cant beat free
[16:21:39] <pfred1> yeah the price was right
[16:21:43] <ReadError> break it down for the steppers ;)
[16:21:50] <pfred1> if it doesn't work
[16:21:54] <CareBear\> I'd like free storage space
[16:22:15] <pfred1> I nessed up the cartridge on my other one running PNP Blue through it for making PCBs
[16:22:37] <pfred1> so I won't be doing that with this one
[16:23:31] <archivist> I bid a pound on a colour laser today got beat 1,20 !!
[16:23:42] <pfred1> CareBear\ this wasn't free but it was extremely cheap http://img7.imageshack.us/img7/8210/72363334.jpg
[16:24:42] <ReadError> i forsee pfred1 on an episode of hoarders in the future
[16:24:45] <Loetmichel> pfred1: looks like some work to do there
[16:25:00] <pfred1> Loetmichel how so?
[16:25:01] <Loetmichel> but could be a nice place to live ;-)
[16:25:12] <pfred1> yeah i have seen folks living rougher
[16:25:17] <archivist> hoarders++
[16:25:22] <Loetmichel> pfred1: roof, walls for example
[16:25:24] <pfred1> luckily I can't see that thing form my house
[16:25:57] <andypugh> Did you see the laser printer I bought from eBay? It looked smaller in the advert. https://picasaweb.google.com/lh/photo/MgB989_mA9lWpQyLHLqPodMTjNZETYmyPJy0liipFm0?feat=directlink
[16:25:58] <pfred1> it took me over 300 feet of extension cords to get power down there to build it
[16:26:06] <pfred1> through dense woods
[16:26:13] <Loetmichel> i would like to live in a house more sturdy and with a more durable roof, and WHITE walls
[16:26:28] <archivist> hoarding is a fine hobby, always have something to play with...just cannot find it
[16:26:32] <pfred1> andypugh that is a pallet
[16:26:33] <andypugh> What's your roof?
[16:26:44] <Loetmichel> (or a light color, nothing dark, especially in non isolated wood walls)
[16:27:06] <Loetmichel> archivist: get som memory training
[16:27:11] <syyl_> you could use that little printer as a anchor
[16:27:13] <pfred1> this is my house it is kind of plain http://i.imgur.com/leC6i.jpg
[16:27:32] <archivist> Loetmichel, nah, its called a database and a search engine
[16:27:44] <Loetmichel> i am a "messie"... but i KNOW whre my stuff is... "this pile over there, about 20cm from top"
[16:28:09] <pfred1> I can't think in terms of metric
[16:28:13] <Loetmichel> archivist: dont need that, have enough internal "grey" memory
[16:28:17] <Loetmichel> 8"
[16:28:28] <pfred1> 8" I can understand
[16:28:33] <archivist> I moved half a ton up the garden today
[16:28:47] <pfred1> I've been doing a lot of gardening lately
[16:29:14] <pfred1> my garden is the size of a lot of people's whole back yards
[16:30:34] <pfred1> my solar pond pump is in the blink
[16:30:35] <Loetmichel> archivist: some time in the pas i had do clean up because it was TOO messy at work. my bos came in the workshop, stopped, looked startled... cam slowly and with an unbelieving face to my desk...
[16:30:39] <archivist> my house circa 1960's http://www.collection.archivist.info/archive/house/page0073.jpeg
[16:30:40] <pfred1> on the blink even
[16:31:10] <Loetmichel> ... knocks on the table... "There is a desk unterneath that? Never seen that before!"
[16:31:11] <Loetmichel> ;-)
[16:31:23] <archivist> Loetmichel, tidying is fatal, never can find anything afterwards
[16:31:26] <pfred1> archivist is that Norman Bates i spy in the top window?
[16:32:35] <pfred1> we don't have street lights around here
[16:35:12] <Loetmichel> archivist: me in the old company where that happened: http://www.cyrom.org/palbum/main.php?g2_itemId=3610
[16:37:42] <archivist> I see everything gets taped up
[16:37:47] <pfred1> this is part of the street I live on no street lights http://i.imgur.com/VtlOd.jpg
[16:37:58] <Loetmichel> archivist: stage rental company
[16:38:04] <pfred1> I just don't drive here at night
[16:38:42] <Loetmichel> pfred1: coward ;-)
[16:38:53] <archivist> you can make a noise at night I cannot
[16:39:02] <pfred1> Loetmichel if you knew how many deer lived around me
[16:39:16] <Loetmichel> so you get a sunday dinner free
[16:39:17] <Loetmichel> ;-)
[16:39:22] <pfred1> Loetmichel when i say herds shoulder ot shoulder for acres I am not exagerrating
[16:39:36] <pfred1> I've seen it
[16:39:59] <Loetmichel> i've hit a wild hog some time ago with my old car...
[16:40:10] <Loetmichel> i know what that means.
[16:40:15] <r00t4rd3d> http://i.imgur.com/lNYra.jpg
[16:40:20] <Loetmichel> @ 50MPH or so
[16:40:40] <pfred1> on top of it there is nowhere around here to go at night anyways
[16:40:55] <Loetmichel> result: http://www.cyrom.org/palbum/main.php?g2_itemId=5453
[16:41:03] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=5456&g2_imageViewsIndex=1
[16:41:21] <Loetmichel> and the hog wasnt in better condition
[16:41:56] <pfred1> I knew a kid that hit a 7 point buck in a 71 Nova and bent the hood over the roof of the car
[16:42:07] <pfred1> it looked like he hit a brick wall
[16:42:13] <Loetmichel> i can imagine
[16:42:25] <pfred1> I saw it and I can't imagine
[16:42:26] <Loetmichel> 1000 pounds of pure muscle and bone
[16:42:39] <Loetmichel> that IS like hitting a wall
[16:42:54] <pfred1> this car was bent in the shape of a J
[16:43:13] <pfred1> kid was alright though tough bugger
[16:43:33] <pfred1> I think well he says he was only doing 65
[16:43:36] <Loetmichel> congrats to him/her
[16:44:28] <Loetmichel> my accident was on a street to the woods from work home
[16:44:31] <Loetmichel> in the dark
[16:44:43] <pfred1> it gets super foggy around here a lot too
[16:44:48] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=5480
[16:45:57] <pfred1> I think for a while the English settled here and they must have felt right at home
[16:45:59] <Loetmichel> the last ting i remember before the chras was "what the f*** does the sheep in the middle of the street?" *BANG*
[16:46:34] <pfred1> they delay school because of fog here
[16:46:38] <Loetmichel> (realized that tas was a hog not a sheep i had only when the police came and shoot it)
[16:47:09] <Loetmichel> pfred1: so what?
[16:47:24] <pfred1> it points out how bad it is
[16:47:31] <Loetmichel> drive slower, only so fast that you can break in the rest-visibility
[16:47:38] <pfred1> this area is really prone to the stuff
[16:47:44] <Loetmichel> brake
[16:48:01] <pfred1> ah it gets so bad you can't see over your own hood
[16:48:26] <pfred1> I mean we really get fog
[16:50:13] <Loetmichel> so buy a pair of IR googles ;-)
[16:50:28] <pfred1> I think that would be a viable solution
[16:51:56] <pfred1> I live between Hollyville and Angola on this map http://g.co/maps/4e7z9
[16:52:30] <pfred1> so I might as well live on a houseboat
[16:52:33] * Loetmichel in the middle of germany
[16:53:01] <Loetmichel> THAT is an option i was contemplating before i got married
[16:53:13] <pfred1> actually i think i might just be in Hollyville
[16:53:38] <pfred1> although I am in the Angola phone exchange
[16:54:05] <pfred1> which is sweet because that means i have fios
[16:54:35] <pfred1> they had to run over 900 feet of fiber from the pole to my house
[16:55:00] <pfred1> just to go through my front yard
[16:56:33] <pfred1> Loetmichel we're very proud of our watchtowers we still have keeping an eye out for Germans here
[16:57:21] <pfred1> Loetmichel http://www.trekearth.com/gallery/photo144245.htm
[16:57:42] <pfred1> I hear it wasn't a cushy assignment in the war either the flies were terrible!
[16:57:42] <Loetmichel> pfred1: not really useful...
[16:58:05] <Loetmichel> IF the germans would invade the us you wuoldnt see them... until its to late ;-)
[16:58:18] <pfred1> ah we caught the bunch that tried
[16:59:27] <pfred1> but yeah there are committies to save the towers now a days and everything
[16:59:46] <pfred1> personally i htink they're eyesores
[17:00:31] <andypugh> Not as weird as these
[17:00:32] <andypugh> http://subterrain.org.uk/maunsell/part4.html
[17:00:47] <pfred1> andypugh you guys have Sealand
[17:00:55] <pfred1> which is on a WW2 gun platform
[17:02:00] <pfred1> at least no one has ever tried to turn any of our towers into a sovereign nation
[17:03:10] <pfred1> http://en.wikipedia.org/wiki/Principality_of_Sealand
[17:04:19] <pfred1> I wonder how that guy from washington state is doing?
[17:04:48] <pfred1> ah ha they found a body
[17:06:21] <pfred1> I think this guy is going to put the nail into the whole prepper movement
[17:06:58] <andypugh> I haven't the slightest idea what you are on about.
[17:07:06] <pfred1> http://www.google.com/hostednews/ap/article/ALeqM5iM5TtetRXKQIF_ljSVAe0buRTAag?docId=3f19b0be80a7442ead91d5e49437c97f
[17:07:21] <pfred1> andypugh prepping is an American thing I think
[17:08:28] <andypugh> I think I can guess what it is about. "Preparedness"?
[17:08:50] <pfred1> andypugh those nuts belong in rubber padded cells
[17:09:00] <andypugh> They are the major bad-guys in "The Postman" and the saviours of the world in "Out of the Dark"
[17:10:17] <pfred1> you can't prepare for doomsday
[17:10:20] <andypugh> "Out of the Dark" makes a convincing case why everyone should have at least two Barratt rifles. Though to be honest a rather promising book is ruined by the arrival of vampires.
[17:11:11] <pfred1> this guy triggered hos own personal doomsday and he didn't last 2 days
[17:12:22] <pfred1> I read a book by Dean Ing called Pulling Through that was about the topic
[17:13:06] <pfred1> OMG I'm rich! http://www.amazon.com/Pulling-Through-Dean-Ing/dp/0441690505
[17:13:38] <pfred1> apparently it is a much sought after tome
[17:55:31] <andypugh> pfred1: I have a copy of this: http://www.amazon.com/Some-Unusual-Engines-L-Setright/product-reviews/0852982089
[17:57:49] <pfred1> andypugh I cannot agree with this review
[17:58:19] <pfred1> "many neat things have happened since 1971" yeah who walked on the Moon?
[17:58:21] <andypugh> How about http://www.amazon.co.uk/Some-Unusual-Engines-L-Setright/product-reviews/0852982089

[19:42:20] <Tom_itx> JT-Shop around?
[19:42:54] <Tom_itx> i wondered if the connectors on the 203v can be mounted to the pins vertical or horizontal... it looks like they can
[19:43:13] <jdhNC> if they fit, you can.
[19:43:18] <jdhNC> I have those on some other things
[19:43:37] <Tom_itx> i mean, it looks like the connector was made to do both
[19:43:52] <jdhNC> the connectors are.
[19:44:06] * Tom_itx logs that in memory
[19:45:14] <ReadError> if i fits, i sits
[20:30:18] <Jymmm> ReadError: Do you need to buy three tickets on airlines for yourself?
[20:34:29] <ReadError> cutting my first ;)
[20:34:43] <ReadError> Jymmm, no im not that respectful
[20:34:50] <Jymmm> lol
[20:36:33] <ReadError> first thing im cutting on new mill: the DERP face
[20:37:00] <ReadError> in acrylic
[20:37:26] <Jymmm> What rpm is your spindle?
[20:38:15] <ReadError> 10k
[20:38:42] <ReadError> seems to be running fine
[20:55:59] <ReadError> millin
[20:56:05] <ReadError> 0.00 for all load averages ;/
[21:15:51] <djdelorie> Not CNC but you metalworkers will appreciate this... I turned my first thread on my 90 year old Southbend lathe: http://www.delorie.com/photos/southbend-lathe/img_2671.html
[21:16:09] <djdelorie> 3/8" x 32 tpi
[21:24:08] <jdhNC> PCW?
[21:25:46] <andypugh> That looks a lot more like a thread than some of mine.
[21:27:27] <djdelorie> my attempt at a 3/8 x 8tpi was very messy, and snapped. I should have tried a 16tpi as that's a standard size, but I wanted something gentle and measurable :-)
[21:27:58] <djdelorie> I was more interested in trying out the chuck and threading gears than actually making something useful
[21:30:27] <ReadError> thread cutting and gear cutting is like machine porn for me ;o
[21:30:32] <jdhNC> DJ: was that always motor driven, or converted at some point?
[21:30:37] <andypugh> Does it have a thread counter?
[21:31:30] <djdelorie> From what I've read, it was designed for shops that had a single large motor that powered all the tools via ceiling-mounted shafts. The motor cage and motor were added post-WWII but the parts came from the original kit
[21:32:00] <andypugh> I have a very similar looking Colchester.
[21:32:01] <djdelorie> Ii.e. the step pulley and v-pulley)
[21:32:25] <djdelorie> My wife has told me that NO I cannot make that lathe a CNC machine :-)
[21:32:29] <jdhNC> I used to work in a chemical plant that had a shop that still had the overhead pulleys
[21:32:36] <andypugh> The 6tpi cross-slide screw with a 1"dia thimble is a bit limiting...
[21:33:04] <andypugh> djdelorie: Does she take well to being proven wrong?
[21:33:18] <djdelorie> One interesting factor on this lathe is that the compound slide does not have a dial indicator on it, you have to guess how far your advancing it.
[21:33:27] <jdhNC> that wouldn't be a nice thing to do to it.
[21:33:45] <jdhNC> you could add a DRO though.
[21:33:51] <djdelorie> She says (rightly so) that "that would be just... wrong." So, my little chinese lathe will likely be the victim if I decide to go that route.
[21:34:06] <andypugh> djdelorie: On the Colchester we tend to fasten a dial indicator onto it to measure cross-slide movement.
[21:34:14] <djdelorie> I thought of that too
[21:34:35] <andypugh> And I agree, it would be wrong to throw so much of it away to convert.
[21:34:39] <djdelorie> I have a mag-base dial indicator I've been using to calibrate it. It's 0.072" per handle rotation, approximately.
[21:35:30] <andypugh> I made the same decision, and converted a cheap Chinese lathe. There is an unexpected problem with this though, you end up with a cheap Chinese lathe still, and that is a real limitation.
[21:36:11] <djdelorie> yeah. Turns out (he he) the ginormous antique lathe is better for turning tiny screws than the tiny modern chinese lathe.
[21:36:34] <jdhNC> a lot more mass for stability.
[21:36:36] <andypugh> djdelorie: 14tpi? Mine is 0.1666" per rev. So .333" on diameter. Which is a bit too much, really.
[21:37:17] <djdelorie> Perhaps I'll get an antique metal mill and use it and the antique lathe to rebuild the chinese lathe :-)
[21:37:53] <djdelorie> jdhNC: the chinese lathe's tool holder is not sturdy enough, the tool keeps getting dragged under the work instead of cutting it. I suspect the gibs or dovetails are the wrong size.
[21:38:05] <djdelorie> it has a lot of wiggle in it
[21:38:36] <jdhNC> which cheap chinese lathe?
[21:39:54] <djdelorie> andypugh: Could be. The crossfeed screw is 8 tpi - the dial goes from 0 to 124
[21:40:15] <djdelorie> it's an older version of the grizzly 7x12
[21:41:13] <djdelorie> but the previous owner tried to convert it from metric to english feed screws, so I have a mishmash of parts in it
[21:41:20] <jdhNC> the 8x's are much sturdier. My jet 9x does the same thing.
[21:42:04] <jdhNC> heh, got a price of $199 shipped for chinese machined ballscrews/nuts for my chinese mill
[21:42:51] <jdhNC> can you fit a ballscrew on a 7x crossslide?
[21:43:26] <andypugh> djdelorie: One part of a CNC conversion is to junk the whole compound slide, so you do gain a fair bit or rigidity that way.
[21:43:32] <djdelorie> I doubt it
[21:44:08] <djdelorie> andypugh: that makes sense. The compound isn't needed that much when the computer can do it all with the other axes
[21:44:41] <jdhNC> a new cross slide with ganged tooling would be nice
[21:44:48] <andypugh> It isn't needed _at_all_
[21:45:02] <djdelorie> jdhNC: I don't think it's the screw that's the problem, I think it's the dovetails and gibs. The gibs don't hold the toolrest *down* like they should
[21:45:53] <jdhNC> I meant for cnc'ing it. Turning a ballscrew would be better than that existing screw.
[21:46:38] <andypugh> Here is my cross-slide balls crew conversion, there might be some useful ideas there: http://www.cnczone.com/forums/mini_lathe/63621-mini_lathe_cross_slide_ballscrew-2.html
[21:46:41] <djdelorie> andypugh: the only use I can think of is if your toolrest didn't rotate to point the tool the way you wanted. I doubt that's a problem though, but the chinese toolrest has stops every 90 degrees
[21:47:12] <andypugh> You change tool, in that case.
[21:47:32] <djdelorie> jdhNC: I suppose so, in that case. I hadn't taken it apart far enough to know what it's like in there.
[21:52:53] <jdhNC> anyone use a pwmgen on a 7i43 and/or 7i47?
[21:53:16] <andypugh> Yes, I use one for spindle control on a 7i43
[21:53:27] <jdhNC> when I exit emc, it gets pulled high, puts out about 1.5mA
[21:54:00] <jdhNC> which is enough to confuse this pwm->analog board (C41)
[21:54:03] <andypugh> Yes. You probably want to use it as a current-sinking pin
[21:54:14] <jdhNC> is that configurable somewhere?
[21:54:30] <andypugh> Well, it's a hardware not software change
[21:55:14] <jdhNC> would a 2.2k to gnd work?
[21:55:43] <Jymmm> jdhNC: WHAT?! I thought that board of your has a chargepump?
[21:56:04] <jdhNC> nope, but you would think it would act similarly
[21:56:23] <Jymmm> Not if it it's not in your mechanical estop chain
[21:56:42] <jdhNC> I meant lack of a valid PWM should make it drop out.
[21:56:58] <Jymmm> Not necessarily.
[21:57:26] <Jymmm> But, if you exit emc, there would be not chargepump, which owuld prevent the spindle from turning
[21:57:27] <jdhNC> it seems to see it as max value
[21:57:50] <Jymmm> s/not/no/
[21:58:16] <jdhNC> chargepump seems like a good addition for safety. This would annoy me anyway though.
[21:58:33] <Jymmm> jdhNC: Get a safety relay off ebay too
[21:58:48] <Jymmm> It's WELL WORTH THE MONEY time and effort
[21:59:05] <andypugh> jdhNC: It is possible that 5V to the PWM terminal and wiring the 7i43 to the GND would work, but I suspect that would rather confuse the REV terminal.
[22:01:14] <andypugh> Outputs floating high when off is a "Feature" of the FPGA chip.
[22:02:12] <jdhNC> the board is powered by 5V also, the power and signal have a common ground
[22:02:28] <Jymmm> jdhNC: Got 24VDC source?
[22:02:42] <jdhNC> yeah
[22:02:51] <Jymmm> jdhNC: http://www.ebay.com/itm/STI-Omron-SR103AM01Safety-Monitoring-Relay-Dual-Channel-with-24VDC-Input-NEW-/330720612220?pt=LH_DefaultDomain_0&hash=item4d007c0f7c
[22:03:28] <jdhNC> cheap.
[22:03:33] <Jymmm> jdhNC: Be aware that the wiring can be confusing until you "get it" how it works.
[22:03:37] <andypugh> What do they actually do?
[22:04:02] <jdhNC> like a multipole, multi-coil contactor
[22:04:14] <Jymmm> jdhNC: no, more than that
[22:04:26] <Jymmm> It's hard to explain.
[22:04:40] <jdhNC> that was the simple explanation.
[22:05:06] <andypugh> Eeek! 4am!
[22:05:09] <andypugh> Night all
[22:05:14] <jdhNC> seeya
[22:05:19] <Jymmm> cconditions have to exist to reset the relay. If triggered, will prevent from being reset until the conditons reexist
[22:05:22] <andypugh> The raster trajectory planner can wait for tomorrow.
[22:05:33] <djdelorie> for you, it *is* tomorrow...
[22:09:16] <Jymmm> This is just too cool... http://www.youtube.com/watch?v=xjzX1puYq-4&feature=share
[22:10:15] <Jymmm> jdhNC: go grab the manual for that safety relay, it might help explain it more.
[22:10:38] <jdhNC> I understand safety relays fine.
[22:10:38] <jdhNC> but, thanks,.
[22:10:42] <Jymmm> k
[22:11:21] <jdhNC> and I agree... first time I had to use one, I just thought wtf? for quite a while.
[22:12:33] <Jymmm> My WTF was mostly due to the fact that I have an illuminated BRB and RESET buttons and I wanted them lit based upon the status of the estop chain
[22:12:54] <Jymmm> If estop was triggered, I wanted the BRB to light up.

[22:13:46] <Jymmm> that sucks! should I look at the pic now?
[22:13:50] <jdhNC> I have those controlled by the PLC. It monitors the safety relay
[22:14:09] <jdhNC> Read: image2gcode?

[23:15:42] <toastydeath> chaps, off topic but needed:
[23:15:58] <toastydeath> does anyone have any resources at all on creating graphics that are accurate to data
[23:16:08] <toastydeath> pref in inkscape or gimp, but anything at all would help
[23:21:15] <freespace> i have done accruate pcbs in inkscape by just setting the units to mm, if that helps
[23:35:23] <toastydeath> yeah, using the point editor stuff is probably what will wind up happening
[23:35:41] <toastydeath> but I've seen references made to other methods of doing it
[23:36:07] <alex4nder> hey
[23:37:17] <toastydeath> yo
