[03:34:15] <mrsun> a servo motor is that just a bldc motor with an encoder? :)
[03:58:35] <cmorley> That is an example of a servo, but a servo motor is a general term. It can be brushed, or have a resolver or even be hydraulic if you wanna get picky :) a servo motor is a motor with feedback to the motor drive.
[04:03:30] <mk0> is iso file at linuxcnc.org with preinstalled 4.5.1 now?
[04:07:28] <cncbasher> mk0: livecd has version 2.5.1
[04:08:03] <mk0> and this too?
http://dsplabs.upt.ro/~juve/emc/ ?
[04:08:17] <mk0> it says "2012 - April"
[04:09:01] <cncbasher> that is old , use official download from linuxcnc.org
[04:10:27] <mk0> http://www.linuxcnc.org/iso/ubuntu-10.04-linuxcnc3-i386.iso - would it be the latest?
[04:10:38] <Jymmm> They are the same thing
[04:11:04] <mk0> okay, thanks
[05:44:36] <MattyMatt> convert me!
http://www.ebay.co.uk/itm/cnc-lathe-/230891194210
[05:45:17] <toastydeath> i wonder which boards are fucked
[05:45:59] <MattyMatt> all of them I guess
[05:46:23] <MattyMatt> 4 dead boards = probably too many connectors :)
[05:47:35] <toastydeath> sad, that looks like a neat control
[05:48:06] <MattyMatt> it'd be a shame if it's all the servo boards and the controller is fine, but I'm guessing that's unlikely and not unsavable if you're prepared to fix at board level
[05:49:13] <MattyMatt> £2k start price rules me out
[06:07:27] <jthornton> is scrap metal worth that much over there?
[06:40:09] <cncbasher> JT: some people have silly ideas especialy when it come to ebay
[06:40:57] <cncbasher> i only paid £800 for my 2 hardinge cnc's haha
[06:41:52] <cncbasher> scrapped one ffor parts and got more than my money back
[06:42:13] <toastydeath> i think the hope is that someone else can use it
[06:42:32] <toastydeath> at least that's how my old shop felt
[06:42:53] <toastydeath> they'd buy and sell used gear when they needed to experiment with shit even though the machine was worth more as scrap, they just sold it for what they bought it
[06:45:33] <cncbasher> theirs a lot of old machines coming up now due to closures as well
[06:46:57] <cncbasher> and machines which have been unused and companys deciding to get rid to make space and release some cash if they can
[06:47:01] <cncbasher> is a bobus
[06:47:05] <cncbasher> bonus
[06:58:50] <archivist> now item 160932812372 is only 20 miles from me
[07:01:18] <cncbasher> get it bought , i see a prime candidate for conversion
[07:02:25] <archivist> I have 0 money
[07:02:46] <archivist> er less then 0
[07:03:01] <cncbasher> isn't it always the case when something appears ..
[07:04:03] <archivist> I really must stop looking at ebay it is too painful
[07:04:09] <jthornton> looks like a kwik switch spindle
[07:04:42] <jthornton> I've stopped looking at flea bay when drinking and have saved thousands of dollars
[07:05:58] <jdh> but think of all the junk you don't need that you missed out on!
[07:07:50] <jthornton> I have enough of that already
[07:08:54] <jdh> http://www.ebay.com/itm/251191221994
[07:09:01] <jdh> I'd sell mine for $1k less!
[07:10:39] <archivist> and then get a proper machine
[07:11:17] <cncbasher> saves using it as an ornament
[07:24:19] <jthornton> yuck, it is raining and the steel truck will be here any time
[07:25:03] <Tom_itx> oh goodie
[07:25:21] <Tom_itx> better get out the backhoe for him
[07:28:35] <jdh> proper is relative. I have no space for what I would consider 'proper'
[08:08:20] <JT-Shop> yikes the lights just blinked
[08:10:56] <jdh> start of the zombie apocalypse?
[08:10:59] <archivist> but you are in america, I thought that was normal
[08:11:12] <jdh> it's not normal here.
[08:11:12] <syyl_> dont let Jymmm that hear
[08:12:05] <JT-Shop> pretty normal in areas with overhead service which covers most of America excecpt big cities
[08:12:17] <archivist> the way all the electrical supply is up on rotting wooden poles amazes me
[08:12:45] <JT-Shop> we have all new ones after the ice storm a few years ago :)
[08:12:57] <jdh> not rotting yet!
[08:13:00] <JT-Shop> most cost effective way to transmit power over long distances
[08:52:19] <MattyMatt> mm bridgport on a pallet. I quite fancy that myself
[08:53:10] <MattyMatt> newflash: a man was stopped today driving a forklift on the hard shoulder of the M6
[08:54:37] <MattyMatt> it'd fit in a tall transit wouldn't it? they say they have loading facilities
[08:55:53] <archivist> transit may be upset about it, would have to be the twin wheel version that can carry a bit of weight
[09:00:03] <MattyMatt> ah I'm dreaming. nowhere to put it
[09:03:22] <archivist> deliver it to here then
[09:12:16] <MattyMatt> if I can camp nearby :)
[09:14:14] <MattyMatt> meh, I can just afford enough materials to make some fiddly small parts in my bedroom factory. I mustn't get ahead of myself
[09:14:28] <MattyMatt> scale up NEXT year, hopefully#
[09:16:30] <archivist> waiting for next year becomes fruitless after a year or three
[09:49:59] <MattyMatt> if I had acess to credit, I'd agree
[09:50:24] <MattyMatt> as I don't, cashflow is king
[09:55:51] <pcw_home> I see that Bridgeport has a nice crotch stirrer handle
[09:58:47] <skunkworks> our brown and sharp has one. The shuttle levers disengage it. SO it swings down and hits you in the shin
[10:00:10] <syyl_ws> friend has a haas tl2 cnc lathe...
[10:00:32] <syyl_ws> the handwheel of the carriage is a real nutcracker...
[10:00:53] <syyl_ws> when the carriage moves in rapid it can hurt badly :D
[10:02:57] * Jymmm grabs the zombiegun and puts syyl_ws's chestnuts roasting over an open mill out of our misery.
[10:03:12] <syyl_ws> hi Jymmm ;)
[10:03:24] <Jymmm> syyl_ws: Yeah, KMA fucker =)
[10:03:30] <archivist> the group the police sang about that sort of thing "don't stand so close to me"
[10:04:05] <syyl_ws> KMA?
[10:04:56] <tjb1> kiss my...
[10:05:25] <syyl_ws> thats not friendly :(
[10:05:45] <Jymmm> syyl_ws:
http://i42.tinypic.com/2l9pjr.jpg
[10:06:06] <syyl_ws> very visual explanation :D
[10:06:29] <Jymmm> syyl_ws: friendly enough for ya?
[10:06:57] <syyl_ws> :)
[10:07:40] <archivist> that reminds me of a mitutoyo calender
[10:12:50] <tjb1> archivist: Going to share?
[10:12:53] <syyl_ws> mh
[10:12:59] <syyl_ws> good ol' mitutoyo
[10:13:01] <syyl_ws> :D
[10:13:43] <Jymmm> Got Milk?
http://i46.tinypic.com/1zzs206.jpg
[10:13:48] <syyl_ws> i even prefer them over mahr
[10:13:50] <jdh> is 60vac input ever normal for a dc drive?
[10:15:58] <archivist> tjb1, it got left on the wall at the last job :(
[10:17:18] <Jymmm> Riot Cow!

http://i44.tinypic.com/14bizx4.jpg
[10:22:20] <pcw_home> DC drives usually use PWM so yes 60 VAC might be read with a AC voltmeter
[10:34:32] <jdh> no, these are fed from a 60vac transformer
[10:39:21] <pcw_home> directly?
[10:41:46] <jdh> 60vac transformer to the drive. Not sure what the motors run
[10:43:42] <jdh> just thought it was odd. We had spares, but they were the 'normal' part number and were 115vac input. Bardac DC drives.
[10:44:01] <pcw_home> Oh thats possible for say ~90V motors
[10:45:10] <pcw_home> (assuming a bridge rectifier/ capacitor filter in the drive)
[11:28:28] <tom3p> how to tell last time anonimas1 logged in?
[11:28:58] <archivist> !seen anonimas1
[11:29:00] <the_wench> last seen in 2012-09-25 00:21:17GMT 838:59:59 ago, saying Ping timeout: 248 seconds
[11:29:27] <tom3p> thx!
[11:30:24] <Jymmm> archivist: It took you 31 seconds?! Geeze yur slow ;)
[11:30:44] <tom3p> hmm, looong time last seen , i just scored a Heidenhain tnc 406 ( 5 axis cnc control for edm ) and he uses heidenhains
[11:45:26] <Jymmm> !seen jacky
[11:45:53] <Jymmm> !seen archivist
[11:46:26] <awallin> it's make-linuxcnc-looklike-anothercontrol times...
[11:47:37] <Jymmm> iLinux?
[11:48:08] <Jymmm> awallin: samsung might sue you for that =)
[11:52:25] <awallin> yeah I bet the pro cnc-control makers engage in patent-wars too..
[12:00:36] <MattyMatt> has anyone thought about porting linuxcnc to pro controllers? or at least the gcode interpreter? what kind of cpu do they have inside?
[12:01:58] <awallin> MattyMatt: that would only make sense if you had cheap access to pro controller hardware
[12:02:46] <MattyMatt> sometimes you do :) we were looking at this earlier
http://www.ebay.co.uk/itm/160932812372
[12:04:29] <MattyMatt> if upgrading was simply a matter of burning a new eprom and piggybacking some more ram in, it'd be neat to use the old control box
[12:05:28] <awallin> I bet the hardware inside those varies a lot..
[12:08:19] <MattyMatt> yeah each one would be a custom project I guess
[12:08:30] <pcw_home> And would be rather dismally slow
[12:09:03] <tom3p> and what about all the open documentation :)
[12:09:08] <pcw_home> My guess is thats a Z80 or some such
[12:09:13] <MattyMatt> bung an arduino in with a pin to eack button, and use it as a big pendant
[12:10:06] <pcw_home> one arduino would probably out run its current CPU
[12:11:22] <tom3p> haha thats a heidenhain 360 control, you actually can get a lot of pinouts from them ( the keyboard is just a matrix plus a fovr pot run off 5v)
[12:11:25] <MattyMatt> yeah documentation would be an issue, if you needed to RE the existing rom
[12:11:53] <tom3p> dont bother trying inside the control, but hacking the peripherals is possible
[12:11:55] <MattyMatt> it says TNC 145 in the listing
[12:12:10] <pcw_home> Is that mid 80's vintage?
[12:12:31] <MattyMatt> yeah amber screen was 80s
[12:12:32] <tom3p> yep, many variants ( 145 has less interp capability/memory/io )
[12:12:59] <MattyMatt> for a few years it was mandatory amber by the ergonomic police
[12:13:42] <pcw_home> And I remember (and you can see) the the amber screens burned-in very quickly
[12:14:28] <MattyMatt> yep they disappeared by 86 when paper white and full color became the fashion
[12:16:07] <pcw_home> I would just gut the box and use the buttons/MPG
[12:16:13] <MattyMatt> yep
[12:16:37] <MattyMatt> mini-itx inside
[12:17:05] <MattyMatt> crt says there's room for a few mesa cards too :)
[12:18:01] <tom3p> tinyurl fails, sorry, but this is repair guide for 145
http://www.google.com/url?sa=t&rct=j&q=tnc+145+service+manual&source=web&cd=3&cad=rja&ved=0CDkQFjAC&url=http%3A%2F%2Fcncdubai.com%2Fspares%2Fmanuals%2FHeidenhain%2FTNC145%2FService%2520instructions%2FService%2520Instructions%2520Heidenhain%2520TNC145%2520controuring%2520control%2520sa145.pdf&ei=UDq-UMrdFcqqywGY-oGoBA&usg=AFQjCNGRRSUWhIy6ag7W37zxEcqIUq-BSQ
[12:19:13] <MattyMatt> neat. I might have a punt for that as I just got wind of a windfall. I don't have transport or anywhere to put it tho
[12:19:19] <pcw_home> TMS9900!
[12:19:32] <MattyMatt> yech :)
[12:19:36] <MattyMatt> ti99/4
[12:19:45] <pcw_home> 16 bit and multiply!
[12:20:02] <pcw_home> BLWP RTWP and all that
[12:20:06] <archivist> registers in ram!
[12:20:06] <MattyMatt> I'm still not RE that rom
[12:20:20] <MattyMatt> z80 I would
[12:21:43] <pcw_home> I still have an old Tek scope with a TMS9900 in it
[12:22:12] <archivist> which model?
[12:23:02] <pcw_home> Its the first 7000 series digital storage mode (7842?)
[12:23:10] <pcw_home> model
[12:24:46] <tom3p> heres much cleaner service pdfs for the 100 series heidenhains
http://content.heidenhain.de/doku/oma_controls/dvd_oma_html/de/index/N12DA1/N12E50/N12E50.html
[12:25:07] <pcw_home> sorry 7854
[12:25:21] <archivist> aw I dont have the manual for that tek to look at the circuit
[12:25:55] <jdh> I used to have a 465b with the storage thing grafted on the top
[12:27:12] <archivist> thing on top was usually a dm44 multimeter
[12:27:18] <pcw_home> so a TMS9900 is about 1 MIP...
[12:28:06] <jdh> it was a mulitimeter, and did horiz & vert measurments with cursor controls
[12:28:49] <jdh> too big to keep around
[12:28:59] <tom3p> haupt-rechner is tms 9995
[12:38:13] <pcw_home> I guess the 9995 was a couple of times faster (an still capable of running DX10!)
[13:00:44] <IchGuckLive> hi all B)
[13:00:55] <DJ9DJ> hi there
[13:02:34] <IchGuckLive> just brok my bit so i stopped milling
[13:03:04] <jdh> why didn't you stop right before it broke?
[13:03:22] <IchGuckLive> ureol Block came loose
[13:06:11] <DJ9DJ> hrhr
[13:06:23] <DJ9DJ> do you only have one bit?
[13:06:33] <DJ9DJ> sorry, did you only... ;)
[13:06:57] <awallin> when I did parts in MDF I used double-stick tape to hold them to the table... has some limitations though..
[13:08:05] <DJ9DJ> hehe, that is what i also do
[13:08:10] <DJ9DJ> double-sided tape :)
[13:08:12] <IchGuckLive> DJ9DJ: no i got hole boxes of but im fustraiting so i stopped
[13:08:15] <DJ9DJ> for wood
[13:09:35] <IchGuckLive> it wars the old fault on Linuxcnc to travel strait to the last point so it went to the part after stopping and correcting the speed
[13:09:35] <IchGuckLive> i lost manyparts on this issue
[13:09:44] * DJ9DJ tried tape for aluminium last time. bad idea, workpiece got loose...
[13:10:00] <IchGuckLive> video is up and youtube is calculating
[13:10:27] <syyl_ws> works for aluminum too, DJ9DJ
[13:10:28] <syyl_ws> :D
[13:10:41] <DJ9DJ> yeah, but not for taping alu on mdf :D
[13:10:44] <syyl_ws> but the part has to have enough surface...
[13:10:45] <syyl_ws> oh
[13:10:54] <DJ9DJ> alu on alu/steel may work ;)
[13:11:01] <syyl_ws> i glue it to a ground piece of steel..
[13:11:07] <DJ9DJ> :)
[13:11:18] <syyl_ws> for small parts i use superglue
[13:11:23] <IchGuckLive> http://www.youtube.com/watch?v=MzdHzjEX2og
[13:11:32] <DJ9DJ> you know, thats the difference between pro and newbie ;)
[13:11:35] <syyl_ws> if i cant chuck it in the vice..
[13:12:27] <IchGuckLive> i got 4 m6 below fixed but it seams to be not enoph on this material clamping is better
[13:12:54] <syyl_ws> metric threads in ureol dont hold up
[13:13:00] <syyl_ws> use a threaded insert
[13:13:05] <archivist> my small parts live on the end of solid till parted off
[13:13:13] <DJ9DJ> panzergewinde!
[13:13:23] <DJ9DJ> (tank thread?) *G*
[13:13:31] <IchGuckLive> yes this woudt work #
[13:13:39] <IchGuckLive> also wood screws
[13:14:35] <IchGuckLive> 50cm till Exit break button is way to long on 800mm/min
[13:14:52] <IchGuckLive> if your reaction time is also added
[13:15:12] <IchGuckLive> MAN i shoudt have nown this
[13:15:12] <DJ9DJ> hihi
[13:15:34] <IchGuckLive> ok give it a next chance tomorrow
[13:18:01] <syyl_ws> why are you going that slow on ureol?
[13:19:20] <IchGuckLive> mill is a chees
[13:20:35] <IchGuckLive> i know on calculations 20k rpm times 0.1mm per teeth and 2 teeth i can go 4000mm/min
[13:27:01] <IchGuckLive> ok by
[14:59:13] <adb> hand lathe
http://www.youtube.com/watch?v=XEibt31OlCA
[15:20:50] <andypugh> There are still chair bodgers using pole lathes in the UK.
[15:22:51] <andypugh> http://www.youtube.com/watch?v=_Inzxe25j9M
[15:23:32] <adb> nice
[15:27:09] <JT-Shop> the lathe construction seems very similar
[15:39:43] <JT-Shop> does the stepconf jog use double step or somehow differ from running in Axis?
[15:40:56] <andypugh> Can you go in to "test axis" then run halcmd show all in the terminal to show what the setup is?
[15:41:31] <mk0> B.C.
[15:44:24] <JT-Shop> halcmd just returns the help for halcmd
[15:44:44] <andypugh> "halcmd show all"
[15:45:02] <JT-Shop> ok, it just clicked in my brain too
[15:47:05] <JT-Shop> I see a paraport reset time, but don't know if it is on or not
[15:47:16] <JT-Shop> http://linuxcnc.org/index.php/english/forum/49-basic-configuration/25909-stepper-runs-better-in-stepconf-than-in-axis#27214
[15:51:56] <skunkworks> I would guess with axis running - his jitter is a lot worse.. I wonder if he ran glx gears and a youtube vid while stepconf jogging
[15:52:04] <skunkworks> it would sound worse
[15:52:27] <skunkworks> has he evern latency tested the machine?
[15:58:44] <andypugh> JT-Shop: halcmd show thread shows that the reset function is running in the fast thread.
[15:59:21] <JT-Shop> is it supposed to?
[15:59:40] <andypugh> Yes
[16:00:04] <JT-Shop> I must have missed it
[16:36:11] <DJ9DJ> gn8
[18:18:02] <JT-Shop> Yea! the 308 made 18 parts and didn't trip out
[19:03:02] <tjb1> JT-Shop: Yay!
[21:47:38] <jdh> any analog help around? This is a plot of mV from a pressure transducer. The downward slope is expected, the spastic samples are not.
http://www.artichoke.org/psi-mv.png
[21:54:00] <Tecan> everyone's trying to make pressure transducers these days like woody norris
[21:54:35] <jdh> ?
[21:56:35] <Theta9> what kind of filter do you have?
[21:57:17] <jdh> none :)
[21:58:23] <Theta9> what does your adc input stage look like?
[22:00:11] <jdh> 0-5vdc from the transducer to a voltage divider to teh ADC chip
[22:00:31] <Theta9> voltage divider?
[22:00:38] <Theta9> ADC is 3.3v or something?
[22:00:49] <jdh> 2.048 I think
[22:01:04] <jdh> http://www.abelectronics.co.uk/products/3/Raspberry-Pi/7/ADC-Pi---Raspberry-Pi-Analogue-to-Digital-converter
[22:01:08] <jdh> that's the board
[22:04:35] <Theta9> does the addition of a capacitor from the input the ground help?
[22:05:27] <jdh> tried a 1uF, did nothing
[22:06:49] <Theta9> how long is the cable?
[22:07:01] <jdh> the readings have a 45ish mV jitter. If I take all pressure off the transducer, the ADC reads 0VDC, but a digital voltmeter reads 40mV ish
[22:07:28] <Theta9> what is the jitter on your power supply?
[22:07:36] <jdh> about 3ft of cat5 with power on one pair, signal on the other (same ground)
[22:08:46] <jdh> dvm shows 10mV on the power
[22:09:56] <jdh> I tried a 47uF on the 12v supply also
[22:16:07] <AR_> what is the output of the transducer, jdh
[22:16:10] <AR_> what voltage
[22:16:23] <jdh> 0-5vdc
[22:16:39] <AR_> ok
[22:16:47] <AR_> and what accuracy are you trying to get?
[22:17:05] <jdh> 1psi would be nice, 5 would be ok
[22:17:20] <jdh> but, it should be better than that
[22:17:34] <AR_> and how many mV per 1psi?
[22:18:43] <AR_> if you need to detect changes of <200mV, i suggest you add filtering
[22:19:01] <jdh> .86mV/psi
[22:19:24] <jdh> I think... 0-5800psi, 0-5vdc
[22:19:55] <AR_> holy crap
[22:20:05] <jdh> I have a differnt one (does 0.5-4.5vdc out) working on an arduino and it's fine.
[22:20:10] <AR_> and you need that whole range?
[22:20:23] <jdh> max is 4200 or so
[22:20:32] <jdh> I don't like to run my compressor higher than that
[22:20:52] <AR_> well, i know you will not get that accuracy without filtering and sheilding
[22:22:02] <jdh> I would have thought so too, but my other one reads perfectly on the other ADC.
[22:22:47] <AR_> odd
[22:23:27] <jdh> it's a different transducer. physically 2x as large
[22:23:29] <Tom_itx> what does the other one do on that adc?
[22:23:37] <Tom_itx> isolate the problem
[22:24:00] <jdh> haven't tried. different pinout on the M12 and I'd have to cap the gas line.
[22:24:04] <jdh> but, I'll try that tomorrow I guess.
[22:26:05] <Tecan> shit iForgot to pull down my pants before pooping again..hehjk
[22:47:48] <Tom_itx> Tecan seems you isolated your problem
[22:48:34] <Tecan> perhaps this was not the bestplacetopostit
[22:48:48] <jdh> I was just going to let it go.
[22:49:34] <Tecan> is it a euphamism for poop ?
[23:07:23] <ben98216> woot woot
